Definitions
- the present invention relates to a dispenser for the dosed dispensing of at least two components received in one reservoir respectively, wherein a separate pumping device is assigned to each reservoir and the pumping devices are equipped with an actuation device for dispensing the components from an output device which is connected to the reservoirs, wherein the actuation device acts on the pumping devices indirectly via a dosing device and the dosing device is equipped with a setting device which can be actuated to change the position of a transmission element acting on the pumping devices for setting the quantity ratio of the components.
- Document EP 1 104 336 A1 discloses a dispenser of the type specified above, which has a setting device for setting the quantity ratio of the components, the setting device having a transmission element which can be swiveled about a swivel axis and which acts on the pumping devices upon execution of a swivel movement.
- the swivel axis of the transmission element is rotated about the vertical axis of the dispenser by means of a setting device.
- an actuation force is exerted on an actuation section of the transmission element for dispensing the components from the reservoirs, such that the transmission element is swiveled about the swivel axis which runs transversely to the longitudinal axis of the dispenser in response to the exertion of the actuation force.
- the translational actuation being necessary in the known dispenser for the purpose of executing a swivel movement of the transmission element about the swivel axis of the transmission element being transversely oriented to the longitudinal axis, in practical applications permits only a very inaccurate dosing of the total quantity of the two components dispensed from the output device.
- the output of a reproducible dispensing quantity of the two components using the known actuation device is only possible when the transmission element executes a full cycle about the swivel axis.
- the output of only a partial quantity of the possible maximum quantity is hardly possible in a reproducible manner, since the reproducible output of a partial quantity requires a correspondingly reproducible execution of a partial cycle of the transmission element.
- the execution of a defined cycle of the transmission element is scarcely possible in the light of the overall very short distance traveled by the transmission element when a swivel movement is executed.
- the present invention is based on the object of providing a dispenser which enables an accurate dosing of a dispensing quantity composed of two components.
- both the setting device for setting the quantity ratio of the components and the actuation device for dispensing the components from the output device, for the purpose of actuation can be rotated about a longitudinal axis of the dispenser.
- the user of a dispenser basically perceives it more convenient to execute the actuations or the settings, which are to be performed by the user at the dispenser during use, by carrying out similar manual movements.
- the manipulation of the dispenser is not required to be altered between the setting of the mixing ratio of the components and the actuation for dispensing of the components in the set mixing ratio. Instead, in both cases a rotational movement about the longitudinal axis of the dispenser needs to be executed.
- the invention is based on the aspect that, for ergonomic reasons, it is much easier for the user of such a dispenser to execute a reproducible rotational movement than it is to execute a translational movement, in particular, in any instance where the travel path available for effecting the translational movement is rather short.
- the setting device of the dosing device has an adjusting housing which can be rotated about the longitudinal axis of a reservoir housing, in which the reservoirs for receiving the components and the pumping devices are received, and in which adjusting housing the transmission element is arranged in a rotationally fixed manner with respect to the adjusting housing and so as to be axially displaceable on the longitudinal axis of the adjusting housing for actuating the pumping devices, wherein the transmission element has a contact surface of an annular design or being formed as a ring segment which has a surface contour changing in shape along its circumference and interacting with the pumping devices.
- the special design of the setting device thus makes it possible to convert a manual rotational movement of the adjusting housing, caused by the user acting upon the adjusting housing from the outside, into an axial or else translational movement of the transmission element, so that on the one hand an advantageous rotational displacement of the setting device with a view to ergonomics is enabled by the user and, on the other hand, the axial adjusting movement of the transmission element enables a functionally reliable actuation of the pumping devices, wherein the horizontal orientation of the transmission element with respect to a vertical orientation of the longitudinal axis of the dispenser is always maintained.
- the setting of the desired quantity ratio between the two components provided for the dispensing is performed by merely rotating the transmission element about the vertical axis of the dispenser and of the adjusting housing until the relative position of the transmission element with respect to the pumping devices is reached, in which the different contact regions of the transmission element defining the quantity ratio are assigned to the pumping devices.
- the actuation device for dispensing the components can have an actuating housing which can be rotated about the longitudinal axis of the dispenser relative to the adjusting housing, said actuating housing being equipped with a guide arrangement to enable the axial displacement of the transmission element, wherein a first guide device of the guide arrangement, which is formed in the actuating housing, interacts with a second guide device of the guide arrangement, which is formed independently of the actuating housing, for converting a rotary movement of the actuating housing into an axial movement of the transmission element.
- the second guide device has a guide section having an axially oriented guide slot and a pin arrangement positioned at the transmission element with at least one radial guide pin which penetrates through the guide slot and with its contact end interacts with the first guide device of the actuating housing.
- the actuating housing for the purpose of forming the first guide device, on its inner wall being coaxially arranged with respect to the guide section of the adjusting housing has a guide path having a contact contour interacting with the contact end of the guide pin and controlling the axial movement of the transmission element, so that the coaxial arrangement of the actuating housing with respect to the adjusting housing enables an overall compact design of the dispenser.
- a detent for the direction of rotation or a definition of a possible direction of rotation can be realized if the axially oriented guide slot formed in the guide section at its lower end has a pin catch for receiving the radial guide pin to define a direction of rotation of the actuation device.
- a particularly advantageous design of the dispenser which contributes to further enhancing the reproducibility of defined dispensing quantities of the dispenser, for the purpose of defining an initial position of the actuation device, in which the pumping devices are not acted upon by the transmission element, has a spring device between a stop formed at the guide section and the transmission element, so that the initial position can be accurately detected by the user with a view to haptics in that resistance against the rotational displacement of the actuation device is minimized in the initial position.
- the stop is formed at the axial end of a pin formed at the bottom of the guide section and extending through an opening formed in a bottom of a central sleeve-shaped indentation of the transmission element, and if the spring device is formed as a helical spring which is arranged in an annular space formed between the pin and the indentation and which extends between the stop and the bottom.
- a latching device which is disposed at an axial end of a latching pin, which is arranged in the guide section, which latching device, in the transmission element being disposed in the initial position, engages behind an edge of a central opening in the transmission element.
- the constructional measures for defining the initial position of the actuation device are carried out in a particularly simple manner, it proves to be advantageous to ensure a reliable functioning if the guide path arranged in the inner wall of the actuating housing is formed as a guide groove, the groove edges thereof, which run in parallel to one another, receiving the guide pin between them.
- the guide section is formed by the adjusting housing and the pin arrangement with the at least one guide pin is formed at the transmission element, such that when the adjusting housing is rotated, the guide section is correspondingly rotated as well.
- the adjusting housing performs an advantageous double function, so that it is possible to correspondingly reduce the number of individual parts.
- a latching device is formed between the adjusting housing and the reservoir housing, which latching device has a plurality of latching positions for a defined assignment of contact regions of the transmission element being formed on the contact surface, and plungers acting on pumping pistons of the pumping devices.
- the latching device facilitates the repeated setting of a relative rotational position between the adjusting housing and the reservoir housing for the purpose of reproducibly setting a mixing ratio.
- the setting of a once set mixing ratio between the components can also be secured by the latching device.
- the latching device is formed as a modular latching unit which can be inserted between the reservoir housing and the adjusting housing and which can be actuated as a function of the direction of rotation with respect to the reservoir housing to enable the relative rotation of the adjusting housing, it is possible to set the direction of rotation by simply exchanging the latching device.
- the latching unit has a first latching element of an annular design which can be connected to the reservoir housing in a rotationally fixed manner, and a second latching element of an annular design, which can be connected to the adjusting housing in a rotationally fixed manner, wherein the latching elements interact with one another via a latching engagement which is produced in a common annular plane with the aid of latching projections, said latching projections being formed by a toothed pawl section, such that the latching unit can be realized by saving a great deal of material and space.
- An elastically resilient latching engagement is enabled if one of the two latching elements has the toothed pawl section only in a ring segment.
- a particularly accurate relative alignment between the reservoir housing and the adjusting housing is enabled if the latching device has a latching axle which is connected to the reservoir housing and which engages with a hub of the transmission element being formed as a latching sleeve to produce a latching engagement.
- latching projections formed on the circumference of the latching axle interact with latching projections formed on the bore wall of the sleeve to produce the latching engagement.
- a particularly functionally reliable design is enabled if the latching projections are formed by a toothed pawl section.
- the guide section is connected to the reservoir housing in a rotationally fixed manner
- the pin arrangement is formed as a guide ring having at least one guide pin.
- the transmission element is received in the guide ring so as to be rotatable and is connected to the adjusting housing in a rotationally fixed manner by means of a radial engagement device, such that when the adjusting housing is rotated, a relative rotation with respect to the guide housing is effected by the same as well. In this way, it can be prevented that the plungers of the pumping devices are acted upon by a torque when a force is exerted on the plungers.
- the engagement device has a setting sleeve in which the transmission element is received in a rotationally fixed manner and so as to be axially displaceable, wherein the setting sleeve produces an engaging connection to the adjusting housing via a setting pin which penetrates radially through the guide section in a setting groove
- the adjusting housing can be formed as an adjusting ring.
- a latching device is formed between the setting sleeve and the guide section, which latching device has a plurality of latching positions for a defined assignment of contact regions of the transmission element being formed on the contact surface, and plungers acting on pumping pistons of the pumping devices, in spite of a possible simple design of the adjusting housing as a ring, a reproducible setting is enabled.
- the contact regions are formed on the contact surface of the transmission element by contact ledges which are arranged in a stepped sequence, irrespective of the surface contour and topography changing along the circumference of the transmission element, it is ensured that identical contact conditions are always created between the transmission element and the plunger independently of the relative position of the transmission element with respect to the plungers of the pumping devices.
- the contact ledges are formed by blind bores which are arranged in a horizontal surface of the transmission element, a particularly accurate adaptation between the contact regions and the plungers of the pumping devices is enabled, such that otherwise potentially occurring wear and tear can be avoided.

- the pin catch 96 interacts with the guide pin 49 of the transmission element 40 , which is guided in the guide slot 95 , such that when the actuating housing 93 of the actuation device 90 is rotated in a clockwise direction, the transmission element 40 is moved upward on the longitudinal axis 25 by the guide web 63 .
- the actuating housing 93 is rotated in an anti-clockwise direction, a translational upward movement of the transmission element 40 is blocked on the longitudinal axis 25 as a result of the retention of the guide pin 49 in the pin catch 96 .

Description
- This application is a United States National Phase application of International Application PCT/EP2011/073811 filed Dec. 22, 2011 and claims the benefit of priority under 35
U.S.C. § 119 of German Patent Applications DE 10 2011 114 568.4 filed Sep. 30, 2011 and DE 10 2011 116 054.3 filed Oct. 18, 2011, the entire contents of which are incorporated herein by reference. - The present invention relates to a dispenser for the dosed dispensing of at least two components received in one reservoir respectively, wherein a separate pumping device is assigned to each reservoir and the pumping devices are equipped with an actuation device for dispensing the components from an output device which is connected to the reservoirs, wherein the actuation device acts on the pumping devices indirectly via a dosing device and the dosing device is equipped with a setting device which can be actuated to change the position of a transmission element acting on the pumping devices for setting the quantity ratio of the components.
- Document EP 1 104 336 A1 discloses a dispenser of the type specified above, which has a setting device for setting the quantity ratio of the components, the setting device having a transmission element which can be swiveled about a swivel axis and which acts on the pumping devices upon execution of a swivel movement. For the purpose of setting the dosing device, the swivel axis of the transmission element is rotated about the vertical axis of the dispenser by means of a setting device. Subsequent to setting the dosing device an actuation force is exerted on an actuation section of the transmission element for dispensing the components from the reservoirs, such that the transmission element is swiveled about the swivel axis which runs transversely to the longitudinal axis of the dispenser in response to the exertion of the actuation force.
- The translational actuation being necessary in the known dispenser for the purpose of executing a swivel movement of the transmission element about the swivel axis of the transmission element being transversely oriented to the longitudinal axis, in practical applications permits only a very inaccurate dosing of the total quantity of the two components dispensed from the output device. Moreover, the output of a reproducible dispensing quantity of the two components using the known actuation device is only possible when the transmission element executes a full cycle about the swivel axis. By contrast, the output of only a partial quantity of the possible maximum quantity is hardly possible in a reproducible manner, since the reproducible output of a partial quantity requires a correspondingly reproducible execution of a partial cycle of the transmission element. However, the execution of a defined cycle of the transmission element is scarcely possible in the light of the overall very short distance traveled by the transmission element when a swivel movement is executed.
- Thus, the present invention is based on the object of providing a dispenser which enables an accurate dosing of a dispensing quantity composed of two components.
- Moreover, it is an object of the invention to provide a dispenser which can be actuated in a simpler manner and thus provides a higher level of actuating convenience on the part of the user.
- In the inventive dispenser, both the setting device for setting the quantity ratio of the components and the actuation device for dispensing the components from the output device, for the purpose of actuation, can be rotated about a longitudinal axis of the dispenser.
- According to the invention, use is made of the aspect that the user of a dispenser basically perceives it more convenient to execute the actuations or the settings, which are to be performed by the user at the dispenser during use, by carrying out similar manual movements. The reason can be seen in particular in the light of the aspect that in the inventive dispenser, the manipulation of the dispenser is not required to be altered between the setting of the mixing ratio of the components and the actuation for dispensing of the components in the set mixing ratio. Instead, in both cases a rotational movement about the longitudinal axis of the dispenser needs to be executed.
- Moreover, the invention is based on the aspect that, for ergonomic reasons, it is much easier for the user of such a dispenser to execute a reproducible rotational movement than it is to execute a translational movement, in particular, in any instance where the travel path available for effecting the translational movement is rather short.
- In a preferred embodiment of the dispenser, the setting device of the dosing device has an adjusting housing which can be rotated about the longitudinal axis of a reservoir housing, in which the reservoirs for receiving the components and the pumping devices are received, and in which adjusting housing the transmission element is arranged in a rotationally fixed manner with respect to the adjusting housing and so as to be axially displaceable on the longitudinal axis of the adjusting housing for actuating the pumping devices, wherein the transmission element has a contact surface of an annular design or being formed as a ring segment which has a surface contour changing in shape along its circumference and interacting with the pumping devices.
- In this advantageous embodiment the special design of the setting device thus makes it possible to convert a manual rotational movement of the adjusting housing, caused by the user acting upon the adjusting housing from the outside, into an axial or else translational movement of the transmission element, so that on the one hand an advantageous rotational displacement of the setting device with a view to ergonomics is enabled by the user and, on the other hand, the axial adjusting movement of the transmission element enables a functionally reliable actuation of the pumping devices, wherein the horizontal orientation of the transmission element with respect to a vertical orientation of the longitudinal axis of the dispenser is always maintained.
- In particular, when the transmission element acts upon the pumping devices, relative movements between the transmission element and the pumping devices are not produced, which may give rise to wear and tear, potentially preventing a reliable and desirably durable as well as secure use of the dispenser.
- The setting of the desired quantity ratio between the two components provided for the dispensing is performed by merely rotating the transmission element about the vertical axis of the dispenser and of the adjusting housing until the relative position of the transmission element with respect to the pumping devices is reached, in which the different contact regions of the transmission element defining the quantity ratio are assigned to the pumping devices.
- Advantageously, the actuation device for dispensing the components can have an actuating housing which can be rotated about the longitudinal axis of the dispenser relative to the adjusting housing, said actuating housing being equipped with a guide arrangement to enable the axial displacement of the transmission element, wherein a first guide device of the guide arrangement, which is formed in the actuating housing, interacts with a second guide device of the guide arrangement, which is formed independently of the actuating housing, for converting a rotary movement of the actuating housing into an axial movement of the transmission element.
- A particularly functionally reliable, and at the same time easily implementable design of the second guide device, is enabled if the second guide device has a guide section having an axially oriented guide slot and a pin arrangement positioned at the transmission element with at least one radial guide pin which penetrates through the guide slot and with its contact end interacts with the first guide device of the actuating housing.
- It is equally particularly advantageous if the actuating housing, for the purpose of forming the first guide device, on its inner wall being coaxially arranged with respect to the guide section of the adjusting housing has a guide path having a contact contour interacting with the contact end of the guide pin and controlling the axial movement of the transmission element, so that the coaxial arrangement of the actuating housing with respect to the adjusting housing enables an overall compact design of the dispenser.
- A detent for the direction of rotation or a definition of a possible direction of rotation can be realized if the axially oriented guide slot formed in the guide section at its lower end has a pin catch for receiving the radial guide pin to define a direction of rotation of the actuation device.
- A particularly advantageous design of the dispenser, which contributes to further enhancing the reproducibility of defined dispensing quantities of the dispenser, for the purpose of defining an initial position of the actuation device, in which the pumping devices are not acted upon by the transmission element, has a spring device between a stop formed at the guide section and the transmission element, so that the initial position can be accurately detected by the user with a view to haptics in that resistance against the rotational displacement of the actuation device is minimized in the initial position.
- It is particularly advantageous if the stop is formed at the axial end of a pin formed at the bottom of the guide section and extending through an opening formed in a bottom of a central sleeve-shaped indentation of the transmission element, and if the spring device is formed as a helical spring which is arranged in an annular space formed between the pin and the indentation and which extends between the stop and the bottom. By means of this measure, a secure housing for the spring device is created so that the function of the spring device is equally ensured even over a long period of use of the dispenser.
- Alternatively to the design of the dispenser with a spring device, for the purpose of defining an initial position of the actuation device, it is equally advantageously possible to make provision for a latching device which is disposed at an axial end of a latching pin, which is arranged in the guide section, which latching device, in the transmission element being disposed in the initial position, engages behind an edge of a central opening in the transmission element.
- In this embodiment of the dispenser, wherein the constructional measures for defining the initial position of the actuation device are carried out in a particularly simple manner, it proves to be advantageous to ensure a reliable functioning if the guide path arranged in the inner wall of the actuating housing is formed as a guide groove, the groove edges thereof, which run in parallel to one another, receiving the guide pin between them.
- It is equally particularly advantageous if for forming the second guide device the guide section is formed by the adjusting housing and the pin arrangement with the at least one guide pin is formed at the transmission element, such that when the adjusting housing is rotated, the guide section is correspondingly rotated as well. In this way, the adjusting housing performs an advantageous double function, so that it is possible to correspondingly reduce the number of individual parts.
- In a particularly advantageous embodiment of the dispenser, for the purpose of the defined relative arrangement of the adjusting housing with respect to the reservoir housing, a latching device is formed between the adjusting housing and the reservoir housing, which latching device has a plurality of latching positions for a defined assignment of contact regions of the transmission element being formed on the contact surface, and plungers acting on pumping pistons of the pumping devices. On the one hand, the latching device facilitates the repeated setting of a relative rotational position between the adjusting housing and the reservoir housing for the purpose of reproducibly setting a mixing ratio. On the other hand, the setting of a once set mixing ratio between the components can also be secured by the latching device.
- If the latching device is formed as a modular latching unit which can be inserted between the reservoir housing and the adjusting housing and which can be actuated as a function of the direction of rotation with respect to the reservoir housing to enable the relative rotation of the adjusting housing, it is possible to set the direction of rotation by simply exchanging the latching device.
- It is particularly advantageous if the latching unit has a first latching element of an annular design which can be connected to the reservoir housing in a rotationally fixed manner, and a second latching element of an annular design, which can be connected to the adjusting housing in a rotationally fixed manner, wherein the latching elements interact with one another via a latching engagement which is produced in a common annular plane with the aid of latching projections, said latching projections being formed by a toothed pawl section, such that the latching unit can be realized by saving a great deal of material and space.
- An elastically resilient latching engagement is enabled if one of the two latching elements has the toothed pawl section only in a ring segment.
- A particularly accurate relative alignment between the reservoir housing and the adjusting housing is enabled if the latching device has a latching axle which is connected to the reservoir housing and which engages with a hub of the transmission element being formed as a latching sleeve to produce a latching engagement.
- It is advantageous if the latching projections formed on the circumference of the latching axle interact with latching projections formed on the bore wall of the sleeve to produce the latching engagement.
- A particularly functionally reliable design is enabled if the latching projections are formed by a toothed pawl section.
- In an advantageous embodiment for forming the second guide device, the guide section is connected to the reservoir housing in a rotationally fixed manner, and the pin arrangement is formed as a guide ring having at least one guide pin. Moreover, the transmission element is received in the guide ring so as to be rotatable and is connected to the adjusting housing in a rotationally fixed manner by means of a radial engagement device, such that when the adjusting housing is rotated, a relative rotation with respect to the guide housing is effected by the same as well. In this way, it can be prevented that the plungers of the pumping devices are acted upon by a torque when a force is exerted on the plungers.
- If the engagement device has a setting sleeve in which the transmission element is received in a rotationally fixed manner and so as to be axially displaceable, wherein the setting sleeve produces an engaging connection to the adjusting housing via a setting pin which penetrates radially through the guide section in a setting groove, the adjusting housing can be formed as an adjusting ring.
- If, for the purpose of the defined relative arrangement of the adjusting housing, a latching device is formed between the setting sleeve and the guide section, which latching device has a plurality of latching positions for a defined assignment of contact regions of the transmission element being formed on the contact surface, and plungers acting on pumping pistons of the pumping devices, in spite of a possible simple design of the adjusting housing as a ring, a reproducible setting is enabled.
- If, according to a particularly advantageous embodiment, the contact regions are formed on the contact surface of the transmission element by contact ledges which are arranged in a stepped sequence, irrespective of the surface contour and topography changing along the circumference of the transmission element, it is ensured that identical contact conditions are always created between the transmission element and the plunger independently of the relative position of the transmission element with respect to the plungers of the pumping devices.
- Moreover, if the contact ledges are formed by blind bores which are arranged in a horizontal surface of the transmission element, a particularly accurate adaptation between the contact regions and the plungers of the pumping devices is enabled, such that otherwise potentially occurring wear and tear can be avoided.
- Advantageous embodiments of the dispenser will be described hereinafter in more detail with reference to the drawings. The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

FIGS. 1 , 2 and 3 in an overall view illustrate adispenser 20 which, as essential component, has amanipulation device 22 which is connected to areservoir housing 21 and which combines asetting device 23 with anactuation device 24, wherein thesetting device 23 and theactuation device 24 are each connected to thereservoir housing 21 relative to each other and so as to be rotatable about alongitudinal axis 25 of thedispenser 20 with respect to thereservoir housing 21. - As is illustrated in particular in
FIGS. 2 and 3 , thereservoir housing 21 essentially serves for receiving tworeservoirs valve device mixing device 30, each valve device being assigned to one reservoir and here arranged above thereservoirs reservoir housing 21, and is finally supplied from the mixing device to anapplicator surface 32 via acommon output device 31, from which surface the mixed components, in the case of thedispenser 20 that is formed as a lip cream applicator in the present case, can be applied to the lips of the user. For covering theapplicator surface 32 when thedispenser 20 is not in use thereservoir housing 21 is equipped with anapplicator cap 33. - As is illustrated in particular in
FIG. 2 ,pumping devices reservoirs reservoirs pistons plunger transmission element 40, which is a part of thesetting device 23 of themanipulation device 22. - The
manipulation device 22 shown inFIG. 2 andFIGS. 4 and 5 is connected to thereservoir housing 21 via alatching connection 41 shown inFIG. 2 . Thesetting device 23 has an adjustinghousing 43, the lower part thereof being formed as aguide section 44 for receiving thetransmission element 40. Thetransmission element 40 in the present case is formed in a sleeve-like manner and has acontact surface 45 being formed of an annular design at the upper axial end of the transmission element and being equipped with a sequence of contact ledges 46 (FIG. 6 ) of an annular design, which in the present case are formed bybottoms 47 of blind bores 48 provided in thecontact surface 45. Thetransmission element 40 at its outer wall has two guide pins 49 being diametrically opposed to each other and being each axially guided in aguide slot 50 formed in theguide section 44 of the adjustinghousing 43 as an oblong hole. - As is apparent from a combined view of
FIGS. 5 , 7 and 10 theguide section 44 of the adjustinghousing 43 at its lower end has a latchingedge 52 adjacent to a bottom 51, which engages behind a latchingweb 55 formed on an inner wall 53 of an actuatinghousing 54 of theactuation device 24 for producing alatching connection 56 between the actuatinghousing 54 and the adjustinghousing 43. - In the latched engagement between the actuating
housing 54 and the adjustinghousing 43, as is in particular shown inFIGS. 10 and 11 , thetransmission element 40 is guided with the aid of acentral bearing sleeve 57 on apin 58 formed at the bottom 51. Thepin 58, in the case of the exemplary embodiment shown inFIG. 10 , at its upper end is equipped with astop 59, here formed as an axial retaining ring, which stop is arranged opposite to a bottom 60 of the bearingsleeve 57 and together with said bottom respectively forms an axial support for ahelical spring 61 arranged on thepin 58. The embodiment shown inFIG. 10 thus enables an axial displacement of thetransmission element 40 on thepin 58 counter to the compressive force generated in this process by thehelical spring 61. In this axial displacement, thetransmission element 40 is guided by the guide pins 49 in theguide slots 30 of theguide section 44 of the adjustinghousing 43. - As is apparent from a comparison of
FIGS. 10 and 12 , which illustrate different cross-sectional views of themanipulation device 22, the blind bores 48 being arranged in thecontact surface 45 of thetransmission element 40 for forming thecontact ledges 46 have different depths, so that the contact ledges formed by thebottoms 47 of the blind bores 48 are disposed at different levels with respect to acentral contact plane 62. Differing herefrom,FIG. 12 illustratescontact ledges 46 being diametrically opposed to each other at a level differing from the level of the centralcontact surface plane 62, so that upon axial displacement of thetransmission element 40 counter to the effect of thehelical spring 61, when theplungers contact ledges 46, saidplungers pistons pumping devices - In
FIGS. 10 and 12 thetransmission element 40 is shown in different cross-sectional views of themanipulation device 22 in its initial position, in which thehelical spring 61 has its maximum possible relaxation and the guide pins 49 abut against the lower stop of theguide slots 50. For the axial displacement of thetransmission element 40 in theguide section 44, the actuatinghousing 54 of theactuation device 24 on its inner wall is equipped with a guide path, in particular shown inFIG. 13 , which here is formed as aguide web 63 having acontact contour 64 which abuts against the guide pins 49 of the transmission element 40 (FIG. 10 ), so that a relative movement of the actuatinghousing 54 of theactuation device 24 about theaxis 25 with respect to the adjustinghousing 43 of thesetting device 23 causes an axial movement of thetransmission element 40 corresponding to the course of thecontact contour 64. - The
contact contour 64 of theguide web 63 has anindentation 65 defining the initial position of thetransmission element 40 such that corresponding to thecontact contour 64 shown inFIG. 13 , a relative movement of the actuatinghousing 54 about thelongitudinal axis 25 in a clockwise direction causes thetransmission element 40 to be axially moved upwardly along anupwards ramp 66. Upon reaching aramp vertex 67, which is illustrated inFIG. 13 in dash-dotted lines, in response to the pretensioning force of thehelical spring 61, thetransmission element 40 is caused to move along anupwards ramp 68 back into asecond indentation 69 which is diametrically opposed to thefirst indentation 65, wherein the actuatinghousing 54 has executed a rotation of 180° about thelongitudinal axis 25. - In the axial forward movement of the
transmission element 40 specified above in the adjustinghousing 43 of thesetting device 23, the adjustinghousing 43 is disposed in a defined relative arrangement with respect to thereservoir housing 21, so that the rotational position of thetransmission element 40 is not changed either with respect to theplungers - As already specified beforehand with reference to
FIG. 10 , the rotational position of the transmission element shown inFIG. 2 , wherein thecontact ledges 46 being diametrically opposed to each other are arranged at the same level, gives rise to a correspondingly identical axial displacement of theplungers pumping devices device 30 and to be dispensed therefrom through theoutput device 31 to theapplicator surface 32. For setting a different mixing ratio between the components received in thereservoirs housing 43 of thesetting device 23 can be rotated about thelongitudinal axis 25 together with the actuatinghousing 54 of theactuation device 54 arranged thereon until axiallyflush contact ledges 46 are assigned to theplungers FIG. 12 , so that contacting of saidcontact ledges 46 in response to a subsequent forward movement of the transmission element against theplungers housing 54 with respect to the adjustinghousing 43 causes theplungers reservoirs device 30 and to be dispensed to theapplicator surface 32. -
FIGS. 14 and 15 in another embodiment show amanipulation device 70 which comprises asetting device 71 and anactuation device 72, which have an adjustinghousing 73 and an actuatinghousing 74 as well as atransmission element 75, which compared to the adjustinghousing 43, the actuatinghousing 54 and thetransmission element 40 of themanipulation device 22 in particular shown inFIGS. 10 and 12 , have modifications which will be explained hereinafter. - For defining an initial position of the
actuation device 72, a latchingpin 78 is provided in aguide section 76 of the adjustinghousing 73 at the bottom 77, said latching pin at its axial end having a latchingdevice 80 formed by elastically formed latchingnoses 79 and engaging behind an openingedge 81 of acentral opening 82 in thetransmission element 75. - For guiding guide pins, which are not shown in greater detail in the view according to
FIG. 14 but which are identical to the guide pins 49 of thetransmission element 40, in aninner wall 83 of the actuating housing 74 a guide path is formed as aguide groove 85 and has groove edges 86, 87 extending in parallel to each other and receiving the guide pins between them, so that both in the event of an upward movement and in the event of a downward movement of the transmission element 75 a reliable positive engagement is produced between the guide device of the actuatinghousing 74 formed by theguide groove 85 and thetransmission element 75. -
FIG. 16 illustrates adispenser 88 which, analogous to thedispenser 20 shown inFIGS. 1 to 3 , is equipped with areservoir housing 21 which is equipped with asetting device 89 and anactuation device 90, which together form amanipulation device 91 and are arranged on a commonlongitudinal axis 25 with thereservoir housing 21. - The
manipulation device 91 is illustrated in an exploded view inFIG. 17 and comprises an adjustinghousing 92 of thesetting device 89 and an actuatinghousing 93 of theactuation device 90. A comparison with themanipulation device 22 shown inFIG. 5 of thedispenser 20 illustrates that the adjustinghousing 92 is equipped with aguide section 94 which, in contrast to theguide section 44 of the adjustinghousing 43, is equipped with aguide slot 95, which at its lower end has apin catch 96 being formed here as a recession. Thepin catch 96 interacts with theguide pin 49 of thetransmission element 40, which is guided in theguide slot 95, such that when the actuatinghousing 93 of theactuation device 90 is rotated in a clockwise direction, thetransmission element 40 is moved upward on thelongitudinal axis 25 by theguide web 63. By contrast, when the actuatinghousing 93 is rotated in an anti-clockwise direction, a translational upward movement of thetransmission element 40 is blocked on thelongitudinal axis 25 as a result of the retention of theguide pin 49 in thepin catch 96. Theguide slot 95 of the adjustinghousing 92 formed in this manner thus defines a direction of actuation and rotation for theactuation device 90. - The
manipulation device 91 of thedispenser 88 further differs from themanipulation device 22 of thedispenser 20 in that it has a modularly formed latchingdevice 97 which has two latchingelements reservoir housing 21 and the adjustinghousing 92, such that the latchingelement 98 is connected in a rotationally fixed manner to thereservoir housing 21 viasurface recessions projections reservoir housing 21 come into engagement. The latchingelement 99 haspawl projections element 99 is connected to the adjustinghousing 92 in a rotationally fixed manner. A latching engagement is produced between the latchingelement 98 and the latchingelement 99 with the aid of atoothed pawl section element 98 and at the latchingelement 99, respectively, and which enables a relative rotation of the latchingelements FIG. 17 with the aid of inclined tooth flanks 108 only in an anti-clockwise direction, so that in the embodiment shown inFIGS. 16 and 17 of thedispenser 88, theactuation device 90 can be actuated in a clockwise direction and thesetting device 89 can be actuated in an anti-clockwise direction. -
FIGS. 18 and 19 in another embodiment show adispenser 110 with amanipulation device 120 which, in contrast to the previously explaineddispenser 88, has a latching device 111 which has a latchingaxle 112 being connected to thereservoir housing 21 in a rotationally fixed manner and engaging with a hub formed as a latchingsleeve 113 of atransmission element 114, thereby producing a latching engagement between atoothed latching section 115 formed on the outer circumference of the latchingaxle 112 and atoothed latching section 116 formed on the bore wall of the latchingsleeve 113. The latchingaxle 112 is equipped with a disc-shapedaxle base 117 which at its upper edge hasprojections reservoir housing 21, and produces a rotationally fixed connection to thereservoir housing 21. -
FIG. 21 illustrates a cross-sectional view of themanipulation device 120 shown inFIG. 20 having the latchingaxle 112 engaging with the latchingsleeve 113 of thetransmission element 114, wherein in the shown exemplary embodiment, thetoothed latching section 115 of the latchingaxle 112 in the cross-section has symmetrically formed latchingteeth 121 which come into engagement with thetoothed latching section 116 of thetransmission element 114 formed by latchinggrooves 122. Due to the symmetrical design of the latchingteeth 121, the latching engagement between the latchingaxle 112 and the latchingsleeve 113 enables a relative rotation both in a clockwise direction and in an anti-clockwise direction. - In contrast hereto, a latching
axle 123 shown inFIG. 23 has atoothed latching section 124 having latchingteeth 125 which are formed in a pawl-like manner and with inclined tooth flanks 126, which enable a relative rotation between the adjusting housing 43 (FIG. 19 ) and the reservoir housing 21 (seeFIG. 18 ) only in an anti-clockwise direction by the latchinggrooves 122 of thetoothed latching section 116 of thetransmission element 114. -
FIGS. 24 to 26 show another embodiment of amanipulation device 130 which, just like themanipulation devices reservoir housing 21, wherein in contrast to themanipulation devices manipulation device 130 has aguide section 132 being formed independently of an adjustinghousing 131 and being formed as a guide housing and being connected in a rotationally fixed manner to thereservoir housing 21 via afastening ring 133 formed at the upper end thereof by means of alatching connection 134. - As is apparent in particular from a combined view of
FIGS. 25 and 26 , theguide section 132 is equipped withguide slots 135 in which aguide pin 136 of a pin arrangement being formed as aguide ring 137 is each received so as to be axially guided therein. - Furthermore, in particular
FIG. 25 illustrates that a latchingengagement 138 is produced at the lower end of theguide section 132 between theguide section 132 and anactuating housing 139 of anactuation device 162 being arranged on theguide section 132 so as to be rotatable. The actuatinghousing 139 on itsinner wall 140 has aguide web 141 having acontact contour 142 being formed with a defined gradient, such that when the actuatinghousing 139 is relatively rotated on theguide section 132, the guide pins 136 slide along thecontact contour 142 and thereby execute an axial movement in theguide slots 135 of theguide section 132, said axial movement being directed either upwardly or downwardly as a function of the direction of rotation of the actuatinghousing 139 and resulting in theguide ring 137 executing a corresponding upward or downward movement. - Provision is made for a
helical spring 148 on apin 144 being formed at a bottom 143 of theguide section 132, said helical spring with one end thereof being supported against a bottom 145 of atransmission element 146 received in theguide section 132 and with the other end thereof being supported against astop 147 arranged on thepin 144. Thehelical spring 148 thus provides for thetransmission element 146 abutting against theguide ring 137, wherein a cup-shapedprojection 149 of thetransmission element 146 engages with aring opening 150 of the guide ring 137 (FIG. 25 ). At the same time, the helical spring ensures that the guide pins 136 of theguide ring 137 in a defined manner rest on the contact contour irrespective of theguide ring 137 executing either an upward movement or a downward movement in theguide section 132. - As is in particular apparent from a combined view of
FIGS. 26 and 27 , in the manipulation device 130 asetting device 161, which serves for the defined setting and rotation of thetransmission element 146 on thelongitudinal axis 25 of themanipulation device 130, is composed of several parts and in addition to the adjustinghousing 131 being formed of an annular or sleeve design here comprises a settingsleeve 151 which is arranged concentrically with respect to the adjustinghousing 131 inside theguide section 132. The settingsleeve 151 is equipped with asetting pin 152 which protrudes radially outwardly and penetrates through a settinggroove 153 being formed in theguide section 132, and upon engagement with aguide pocket 155 formed on aninner wall 154 of the adjustinghousing 131, produces a rotationally fixed connection to the adjustinghousing 131, such that when the adjustinghousing 131 is rotated about thelongitudinal axis 25 of themanipulation device 130, the settingsleeve 151 is forced to rotate as well. In this manner, the radial travel path being traveled by thesetting pin 152 is limited byradial stops groove 153. As is apparent in particular from a combined view ofFIGS. 25 and 27 , thetransmission element 146 on its inner wall is equipped with acontact surface 159 havingcontact ledges 170 in aring segment 160, which are arranged in a longitudinal direction along the circumference in both directions so as to ascend starting from a low positionedcentral contact ledge 170 defining a central position. - As is illustrated in particular in
FIG. 25 , thetransmission element 146 at itsouter wall 172 hasfollower projections 173 engaging withfollower receptacles 175 formed on aninner wall 174 of the settingsleeve 151. By means of this aspect, thetransmission element 146 is axially displaceable within the settingsleeve 151 and is received in the settingsleeve 151 in a rotationally fixed manner with respect to thelongitudinal axis 25 of themanipulation device 130, such that when the outer adjusting 131 housing is rotated about thelongitudinal axis 25, thetransmission element 146 executes a corresponding rotation about thelongitudinal axis 25 as well. - For the purpose of the defined relative arrangement of the adjusting
housing 131, thetransmission element 146 and theguide section 132 being connected in a rotationally fixed manner to thereservoir housing 21, a latching device 171 shown inFIG. 28 is provided between the settingsleeve 151 and theguide section 132, such that a latchingnose 176 being formed at the outer wall of the settingsleeve 151 interacts with a plurality of latchingcatches 178 being formed along the circumference in the inner wall of theguide section 132, wherein by overcoming a rotational resistance, which determines a defined latching position, a change can be made between the settingsleeve 151 and the guide section from a defined rotational position, in which the latchingnose 176 engages with afirst latching catch 178, into another defined rotational position, in which the latchingnose 176 engages with another latchingcatch 178. - Due to the advantageous guiding and receiving of the
transmission element 146 in theguide ring 137, during the axial displacement of theguide ring 137 within theguide section 132 in response to a rotation of the actuatinghousing 139 with respect to theguide section 132 being arranged at thereservoir housing 139 in a rotationally fixed manner, a torque is not transmitted to thetransmission element 146, so that a torque of thetransmission element 146 cannot act on theplungers pumping devices FIG. 2 , which may give rise to component failure of theplungers - While specific embodiments of the invention have been shown and described in detail to illustrate the application of the principles of the invention, it will be understood that the invention may be embodied otherwise without departing from such principles.
