Definitions
- the present disclosure generally relates to assemblies that include a container and a removable closure associated therewith. More specifically, the present disclosure relates to a closure having a tab, which is configured to facilitate removal of the closure from an associated container.
- Container assemblies are useful for storing products therein.
- container assemblies may be used to store prepared food products, such as soups, pastas, and other foodstuffs.
- Container assemblies may include a container and a removable a closure.
- the container includes a removable top portion that may be separated from the rest of the container to expose the contents therein.
- the container holds a quantity of dry, liquid, or semi-liquid product, such as foodstuffs, therein.
- the container may have a generally cylindrical shape and a generally flat bottom.
- the cylindrical portion of the container defines a cavity suitable to contain the product.
- the flat bottom stabilizes the container when the container is placed on a flat surface, such as a table. Users may withdraw the product within the container through an opening in the top of the container.
- Some containers are made of materials that may be placed in a microwave oven, enabling users to heat the product within the container easily and quickly.
- the container may further include a lip that defines the opening in the top of the container after the removable top portion is separated from the lip.
- the lip may be part of a separate structure that is attached to the generally cylindrical wall of the container, or alternatively may be formed integral with the cylindrical wall. The lip may cooperate with the closure to ensure the closure remains secured to the container.
- the removable top portion closes the opening in the top of the container to prevent the product within the container from spilling and/or leaking from the container through the opening. Additionally, the removable top portion may form an air and liquid impervious seal that preserves the freshness of a food product stored within the container.
- the removable top portion When closing the opening of the container, the removable top portion is connected to the lip.
- the removable top portion may include a pull tab or other similar device to assist a user in detaching the removable top portion from the rest of the container. Once the removable top portion has been detached from the container, it may not be reattached thereto.
- the closure is configured to be removably connected to the container.
- the closure fits over the lip and the removable top portion.
- the closure may be coupled to the container to prevent some of the food product within the container from splattering out of the container while the food product is being heated in a microwave oven.
- the closure may define a space into which the lip of the container is fitted when the closure is connected to the container to ensure the closure remains coupled to the container. Removal of the closure from the container does not require a separate tool; however, removal of the closure from the container may be relatively difficult since the closure may need to be temporarily distorted and forced over the lip.
- some closures incorporate movable locking portions to facilitate removal of the closure from the container.
- the movable locking portions block removal of the closure from the associated container; however, when moved to a second position the locking portions allow removal of the closure from the container.
- Such closures may still be difficult to remove from a container because the locking portions may require use of a relatively large removal force or may be inconveniently situated.
- known locking portions that do not require the use of a large removal force tend to only lightly engage the container and may easily become undesirably separated from the container.
- a container and closure assembly includes a container defining an opening and having a lip positioned around the opening.
- the lip defines a top surface, a bottom surface, and an outer surface therebetween.
- the container and closure assembly also includes a closure configured to be attached to the container.
- the closure includes a top portion defining a circular periphery, and a first skirt portion extending downwardly from the circular periphery to form a cylindrical structure defining a first internal closure space.
- the closure also includes a second skirt portion extending downwardly from a first part of the cylindrical structure.
- the second skirt portion has a first side edge and a second side edge that are spaced apart from each other to form a gap.
- the closure also includes a tab extending downwardly from a second part of the cylindrical structure and positioned in the gap.
- the closure further includes a first vertex segment attached to the second skirt portion, a second vertex segment attached to the tab, and a plurality of spaced apart ribs.
- the plurality of spaced apart ribs are positioned at least partially in the first internal closure space, and are attached to both the top portion and the cylindrical structure.
- a closure includes a top portion defining a circular periphery, and a first skirt portion extending downwardly from the circular periphery to form a cylindrical structure defining a first internal closure space.

- a user may separate the top portion from the rest of the container 14 .
- the top portion is separated by grasping a pull tab connected to the top portion, and pulling the pull tab away from the container 14 as is known in the art. Separation of the top portion from the container 14 creates the opening 30 through which the food product may be withdrawn from the container.
- the user reattaches to the closure 18 to the container 14 after removing the top portion.
- a user places the closure 18 on top of the container 14 such that the internal closure space 166 surrounds the upper portion of the container 14 .

Additionally, the top portion 50 of the closure 18 prevents the food product from boiling over or spattering as the microwave oven heats the food product. Additionally, the vent holes 66 permit steam to advance out of the container and closure assembly 10 . After the microwave oven has heated the food product to the desired temperature, the closure 18 may be removed from the container 14 as described above.

Description
- The present disclosure generally relates to assemblies that include a container and a removable closure associated therewith. More specifically, the present disclosure relates to a closure having a tab, which is configured to facilitate removal of the closure from an associated container.
- Container assemblies are useful for storing products therein. In particular, container assemblies may be used to store prepared food products, such as soups, pastas, and other foodstuffs. Container assemblies may include a container and a removable a closure. The container includes a removable top portion that may be separated from the rest of the container to expose the contents therein. In use, the container holds a quantity of dry, liquid, or semi-liquid product, such as foodstuffs, therein. The container may have a generally cylindrical shape and a generally flat bottom. The cylindrical portion of the container defines a cavity suitable to contain the product. The flat bottom stabilizes the container when the container is placed on a flat surface, such as a table. Users may withdraw the product within the container through an opening in the top of the container. Some containers are made of materials that may be placed in a microwave oven, enabling users to heat the product within the container easily and quickly.
- The container may further include a lip that defines the opening in the top of the container after the removable top portion is separated from the lip. The lip may be part of a separate structure that is attached to the generally cylindrical wall of the container, or alternatively may be formed integral with the cylindrical wall. The lip may cooperate with the closure to ensure the closure remains secured to the container.
- The removable top portion closes the opening in the top of the container to prevent the product within the container from spilling and/or leaking from the container through the opening. Additionally, the removable top portion may form an air and liquid impervious seal that preserves the freshness of a food product stored within the container. When closing the opening of the container, the removable top portion is connected to the lip. The removable top portion may include a pull tab or other similar device to assist a user in detaching the removable top portion from the rest of the container. Once the removable top portion has been detached from the container, it may not be reattached thereto.
- The closure is configured to be removably connected to the container. In particular, before use, the closure fits over the lip and the removable top portion. Additionally, after the top portion has been removed from the rest of the container, the closure may be coupled to the container to prevent some of the food product within the container from splattering out of the container while the food product is being heated in a microwave oven.
- The closure may define a space into which the lip of the container is fitted when the closure is connected to the container to ensure the closure remains coupled to the container. Removal of the closure from the container does not require a separate tool; however, removal of the closure from the container may be relatively difficult since the closure may need to be temporarily distorted and forced over the lip.
- In order to securely engage the container, but be readily removable therefrom, some closures incorporate movable locking portions to facilitate removal of the closure from the container. When in a first position the movable locking portions block removal of the closure from the associated container; however, when moved to a second position the locking portions allow removal of the closure from the container. Such closures, nonetheless, may still be difficult to remove from a container because the locking portions may require use of a relatively large removal force or may be inconveniently situated. Additionally, known locking portions that do not require the use of a large removal force tend to only lightly engage the container and may easily become undesirably separated from the container.
- What is needed, therefore, is an improved container assembly. What is further needed is a closure that securely attaches to an associated container when coupled to the container, yet is readily removable therefrom.
- According to one embodiment of the present disclosure, a container and closure assembly is provided. A container and closure assembly includes a container defining an opening and having a lip positioned around the opening. The lip defines a top surface, a bottom surface, and an outer surface therebetween. The container and closure assembly also includes a closure configured to be attached to the container. The closure includes a top portion defining a circular periphery, and a first skirt portion extending downwardly from the circular periphery to form a cylindrical structure defining a first internal closure space. The closure also includes a second skirt portion extending downwardly from a first part of the cylindrical structure. The second skirt portion has a first side edge and a second side edge that are spaced apart from each other to form a gap. The closure also includes a tab extending downwardly from a second part of the cylindrical structure and positioned in the gap. The closure further includes a first vertex segment attached to the second skirt portion, a second vertex segment attached to the tab, and a plurality of spaced apart ribs. The plurality of spaced apart ribs are positioned at least partially in the first internal closure space, and are attached to both the top portion and the cylindrical structure. When the closure is secured to the container, the top surface of the lip is positioned in contact with the plurality of spaced apart ribs, the bottom surface of the lip is positioned in contact with both the first vertex segment and the second vertex segment, and the outer surface of the lip is positioned in contact with the second skirt portion.
- According to yet another embodiment of the present disclosure, a closure is provided. The closure includes a top portion defining a circular periphery, and a first skirt portion extending downwardly from the circular periphery to form a cylindrical structure defining a first internal closure space. The closure further includes a second skirt portion extending downwardly from a first part of the cylindrical structure. The second skirt portion includes a first side edge and a second side edge that are spaced apart from each other to form a gap. The closure further includes a tab extending downwardly from a second part of the cylindrical structure and positioned in the gap. The closure still further includes a first vertex segment attached to the second skirt portion, a second vertex segment attached to the tab, and a plurality of spaced apart ribs. The plurality of spaced apart ribs are each positioned at least partially in the first internal closure space and are attached to both the top portion and the cylindrical structure.

FIG. 7 is a fragmentary, side elevational view of the closure of the container and closure assembly ofFIG. 1 , however, showing an alternative shape of the top portions of theslits - According to the present disclosure and referring now to
FIG. 1 , a container andclosure assembly 10 is shown. The container andclosure assembly 10 includes acontainer 14 and aclosure 18. Thecontainer 14 holds a quantity of dry, liquid, and/or semi-liquid product. In particular, thecontainer 14 may be used to contain a food product for human consumption. Accordingly, thecontainer 14 may be made from materials that are conventionally used for the storage and after-purchase heating of food products. Specifically, thecontainer 14 may be made from materials that enable a user to heat the food product stored within thecontainer 14 by placing thecontainer 14 in a microwave oven, as described below. - As shown in
FIG. 2 , thecontainer 14 includes abody 22 and alip 26. Thebody 22 may have any shape that is suitable to contain a food product. For instance, thebody 22 may have an approximately cylindrical, elliptical, rectangular, or other polygonal shape. The bottom of thebody 22 is closed to contain the food product therein; however, anupper end 34 of thebody 22 defines anopening 30 through which a product contained within thecontainer 14 may be withdrawn. - Referring now to
FIG. 3 , thelip 26 includes surfaces that cooperate with theclosure 18 to secure theclosure 18 to thecontainer 14. Thelip 26 is connected to theupper end 34 of thebody 22, and is positioned completely around theopening 30. Thelip 26 may be separately made and connected to thebody 22. For instance, thelip 26 may be a metallic component that is coupled to apolymeric body 22 as is conventional in the art of containers of this type. Alternatively, thelip 26 may be integrally formed with thebody 22 by a thermoplastic molding process so that both thelip 26 and thebody 22 collectively define a single polymeric component. - The
lip 26 defines atop surface 38 and abottom surface 42. Thelip 26 further defines anouter surface 46 positioned between thetop surface 38 and thebottom surface 42. Each of thetop surface 38, thebottom surface 42, and theouter surface 46 are configured to interface with a portion of theclosure 18 when theclosure 18 is coupled to thecontainer 14. Depending on the shape of the lip 26 a distinct separation between thetop surface 38,bottom surface 42, andouter surface 46 may not be readily discernable. For instance, thelip 26 may have a largely rounded shape without sharp corners to define the surfaces. Accordingly, thetop surface 38,bottom surface 42, andouter surface 46 refer to the top, bottom, and outer portions of thelip 26 regardless of whether the surfaces are clearly defined. - A top portion (not illustrated) of the
container 14 may be removably connected to thelip 26 of thecontainer 14. The top portion may cover theopening 30 and provide an air-tight seal for thecontainer 14. Accordingly, food products may be stored in thecontainer 14 for a substantial period of time without spoiling. A circular score line (not shown) may be defined in the top of the container to facilitate separation of the top portion from the lip so as to allow easy opening and access to the contained food product without the need for an additional tool such as a can opener. Additionally, the top portion may include a pull tab (not shown) to facilitate separation of the top portion from the rest of thecontainer 14. - The
closure 18 of the container andclosure assembly 10 may be detached from thecontainer 14 to expose the top portion of the container. After theclosure 18 is detached from thecontainer 14, the top portion may be separated from the rest of thecontainer 14 to create theopening 30 through which a food product may be withdrawn from thecontainer 14. Thereafter, as shown inFIG. 1 , theclosure 18 may be reattached to thecontainer 14. Then, the container and closure assembly 10 (now without its container top portion) may be placed in a microwave oven for heating of the food product contained in thecontainer 14. - The
closure 18 may be made from materials conventionally used for the storage and after-purchase heating of food products. Exemplary, materials for making theclosure 18 include, but are not limited to, polypropylene (“PP”) and other injection moldable thermoplastics. Specifically, theclosure 18 may be made from nucleated PP having a density of approximately 0.800 to 1.00 grams per cubic centimeter and a melt index of approximately 50 to 170 grams per 10 minutes. - As shown in
FIGS. 1-3 , theclosure 18 includes atop portion 50, askirt portion 54, and askirt portion 58. Thetop portion 50 defines a periphery of theclosure 18. In particular, thetop portion 50 may define acircular periphery 62; however, thetop portion 50 may define a periphery of any shape as required by the shape of theopening 30. Thetop portion 50 may have a diameter between approximately 9.0 to 12.0 centimeters and may be formed of a material having a thickness of approximately 0.20 to 0.60 millimeters. Additionally, thetop portion 50 may include a plurality of vent holes 66 to allow steam to pass throughclosure 18. - Referring to
FIGS. 1-3 , theskirt portion 54 extends downward from thecircular periphery 62 of thetop portion 50 to form acylindrical structure 70 defining aninternal closure space 74. Theskirt portion 54 may extend downward from thecircular periphery 62 approximately 0.30 to 0.70 centimeters. Theskirt portion 54 may have a thickness of approximately 0.4 to 0.8 millimeters. - Referring now to
FIG. 1 , theskirt portion 58 extends downward from apart 78 of thecylindrical structure 70. In particular, theskirt portion 58 may extend downward from thepart 78 of thecylindrical structure 70 approximately 0.7 to 1.2 centimeters. Theskirt portion 58 includes aside edge 82 and aside edge 86 that are spaced apart from each other to form agap 90. As shown most clearly inFIG. 5 , theskirt portion 58 may also include abottom skirt portion 94 that defines askirt ridge 98. Theskirt ridge 98 extends from theside edge 82 to theside edge 86. Additionally, when theclosure 18 is secured to thecontainer 14 theskirt portion 58 contacts theouter surface 46 of thelip 26. - The
closure 18 further includes a plurality of spaced apartribs 102 that increase the rigidity of theclosure 18. Theribs 102 are positioned at least partially in the firstinternal closure space 74 and are attached to both thetop portion 50 and thecylindrical structure 70. Theribs 102 may be located completely within the firstinternal closure space 74 as shown inFIG. 2 . Theribs 102 extend from the top portion 50 a distance approximately equal to the distance theskirt portion 54 extends from thecircular periphery 62. As shown inFIG. 4 , theribs 102 have a width W that is between approximately 3.0 to 10.0 millimeters. Additionally, theribs 102 may be approximately equally spaced apart along thecylindrical structure 70 as shown inFIG. 4 . - When the
closure 18 is coupled to thecontainer 14, theribs 102 are configured to become seated upon thelip 26, as shown inFIG. 5 . In particular, theribs 102 define a plurality of bottom rib edges 106 configured to contact thetop surface 38 of thelip 26 when theclosure 18 is secured to thecontainer 14. Additionally, the bottom rib edges 106 define a plane P. The plane P forms a boundary between theskirt portion 54 and theskirt portion 58. In particular, theskirt portion 54 is located above the plane P, and theskirt portion 58 is located below the plane P. - Referring again to
FIG. 1 , theclosure 18 includes atab 110 that may be moved or pivoted from a default or relaxed position (see FIG. 3—solid lines) to an unrelaxed position (see FIG. 3—phantom lines). When thetab 110 is located in the unrelaxed position, theclosure 18 is unlocked from thecontainer 14 and may be easily removed therefrom. On the other hand, when thetab 110 is located in its relaxed position, theclosure 18 is locked to (or positively engaged with) thecontainer 14. - The
tab 110 extends downward from apart 114 of the cylindrical structure 70 (see, e.g.,FIG. 1 ). As shown inFIG. 4 , thetab 110 is positioned in agap 90 defined by arib 118 and arib 122. In particular, therib 118 has a surface that defines a plane P1. Likewise, therib 122 has a surface that defines a plane P2. Thetab 110 is located completely between the plane P1 and the plane P2 to enable thetab 110 to move easily from its relaxed position (solid inFIG. 3 ) to its unrelaxed position (phantom inFIG. 3 ). Additionally, thetab 110 defines a width that extends from theside edge 82 to theside edge 86. The width of thetab 110 is approximately 1.0 to 3.0 centimeters. - Referring now to
FIGS. 6 and 7 , theclosure 18 defines aslit 126 and aslit 130 that forms thetab 110. Theslits tab 110 from theskirt portion 58. Theslit 126 is defined between theside edge 82 of theskirt portion 58 and thetab 110. Likewise, theslit 130 is defined between theside edge 86 of theskirt portion 58 and thetab 110. Additionally, the position of theslits slit 126 may be located between the plane P1 and the plane P2. Likewise, theslit 130 is located between the plane P1 and the plane P2. - The
slit 126 and theslit 130 each extends from the bottom to the top of theskirt portion 58. Theslits first skirt portion 54. As shown inFIGS. 6 and 7 , theslit 126 defines aclosed slit end 134 and theslit 130 defines aclosed slit end 138. Both theclosed slit end 134 and theclosed slit end 138 lie within the plane P. Note that theclosed slit end 134 and theclosed slit end 138 do not extend into theskirt portion 54. Alternatively, as shown inFIG. 7 , the closed slit end 134′ and the closed slit end 138′ may have a rounded or radiused shape. - The process used to form the
slits closure 18. For instance, if theclosure 18 is formed utilizing an injection molding machine, theslits closure 18 corresponding to theslits slits closure 18 after the rest of theclosure 18 is formed. For example, a heated cutting instrument or a traditional cutting instrument may be used to cut theslits closure 18. - As shown in
FIG. 3 , thetab 110 may include abottom tab portion 142 which defines atab ridge 146. Thetab ridge 146 may frictionally engage a user's finger to enable thetab 110 to be easily pivoted from the relaxed position (solid lines) to the unrelaxed position (phantom lines). Thetab ridge 146 may extend from theslit 126 to theslit 130 as shown inFIGS. 6 and 7 . - The
closure 18 further includes at least two detents provided as protrusions, protuberances, orvertex segments closure 18 to thecontainer 14. Thevertex segment 150 is attached to the skirt portion 58 (seeFIGS. 2 and 4 ). Thevertex segment 154, as shown inFIGS. 2 , 3, 4, 6, and 7, is attached to thetab 110. When theclosure 18 is coupled to thecontainer 14, thevertex segments lip 26 to secure theclosure 18 to thecontainer 14. To remove theclosure 18 from thecontainer 14, thetab 110 is moved to the unrelaxed position (as shown in phantom inFIG. 3 ) so that thevertex segment 154 is disengaged from thelip 26 thereby permitting theclosure 18 to be easily removed from thecontainer 14. - The
vertex segment 150 has a length that extends for a distance at least partially around theskirt portion 58. In particular, thevertex segment 150 extends for a distance D1 as shown inFIG. 4 . Similarly, thevertex segment 154 has a length that extends for a distance at least partially around thetab 110. In particular, thevertex segment 154 extends for a distance D2 as shown inFIG. 4 . For example, thevertex segment 154 may extend from theslit 126 to theslit 130. The distance D1 is approximately equal to the distance D2. - Referring to
FIG. 2 , thevertex segments closure 18 to thecontainer 14 by overlapping with thelip 26. In particular, when theclosure 18 is secured to thecontainer 14 thebottom surface 42 of thelip 26 is positioned in contact with thevertex segments vertex segments upper surface bottom surface 42 of thelip 26 when theclosure 18 is coupled to thecontainer 14. Theflat surfaces bottom surface 42 of thelip 26 between approximately 0.8 to 1.5 millimeters. A greater amount of overlap between theflat surfaces bottom surface 42 of thelip 26 may result in aclosure 18 that is more securely coupled to thecontainer 14. For instance, when thetab 110 is in its relaxed position (solid inFIG. 3 ), theflat surface 158 and theflat surface 162 are configured to abut thebottom surface 42 of thelip 26. Accordingly, theflat surfaces closure 18 from being removed from thecontainer 14 when thetab 110 is in the relaxed position. As mentioned above, however, thetab 110 may be moved to its unrelaxed position (phantom inFIG. 3 ) in whichflat surface 162 is spaced apart from theupper end 34 of thecontainer 14 and does not overlap thebottom surface 42 of thelip 26. When thetab 110 is in its unrelaxed position, theflat surface 162 is spaced apart from thelip 26 thereby permitting theclosure 18 to be easily removed from thecontainer 14. - As shown in
FIGS. 2 and 3 , the position of thevertex segments internal closure space 166. In particular, theskirt portion 58 and thetab 110 lies in anannular space 170. Theannular space 170 encircles theinternal closure space 166. Both thevertex segment 150 and thevertex segment 154 are located in theinternal closure space 166. - In operation, the container and
closure assembly 10 may be used to contain a food product contained therein. Typically, a user prepares the food product stored within thecontainer 14 for consumption by first removing theclosure 18 from thecontainer 14. To remove theclosure 18 from thecontainer 14 the user grasps thetab 110 and moves it from its relaxed position to its unrelaxed position in the direction of arrow A shown inFIG. 3 . While holding thetab 110 in its unrelaxed position, the user applies an upward force to theclosure 18 in the direction of arrow B shown inFIG. 2 to lift thevertex segment 154 away from thelip 26. Oncevertex segment 154 has been lifted away from the lip, theclosure 18 may be easily removed from thecontainer 14. Thereafter, pressure on thetab 110 may be relaxed so that thetab 110 returns to its relaxed state. - After removing the
closure 18 from thecontainer 14, a user may separate the top portion from the rest of thecontainer 14. The top portion is separated by grasping a pull tab connected to the top portion, and pulling the pull tab away from thecontainer 14 as is known in the art. Separation of the top portion from thecontainer 14 creates theopening 30 through which the food product may be withdrawn from the container. - If the user desires to heat the food product stored in the
container 14, the user reattaches to theclosure 18 to thecontainer 14 after removing the top portion. To reattach theclosure 18 to thecontainer 14, a user places theclosure 18 on top of thecontainer 14 such that theinternal closure space 166 surrounds the upper portion of thecontainer 14. Next, the user applies a downward force to thetop portion 50 in the direction of arrow C shown inFIG. 2 thereby causing thevertex segments lip 26 of thecontainer 14 as described above. The downward force may also be applied to thecircular periphery 62 until theupper surface 38 of thelip 26 is seated upon the bottom rib edges 106. - Once the
closure 18 has been reattached to thecontainer 14, the container andclosure assembly 10 may be placed in a microwave oven to heat the food product contained in thecontainer 14. Thevertex segments closure 18 remains securely coupled to theclosure assembly 10 during the heating process. Additionally, thetop portion 50 of theclosure 18 prevents the food product from boiling over or spattering as the microwave oven heats the food product. Additionally, the vent holes 66 permit steam to advance out of the container andclosure assembly 10. After the microwave oven has heated the food product to the desired temperature, theclosure 18 may be removed from thecontainer 14 as described above. - Variations and modifications of the present invention as described above are possible; however, all variations and modifications which are obvious to those skilled in the art to which the present invention pertains are considered to be within the scope of the protection granted by this Letters Patent.
