The hydrochromic material may have a first appearance when in a dry form and a second appearance, different from the first appearance, when the hydrochromic material becomes hydrated.
Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 60/578,826 filed on Jun. 14, 2004, which is incorporated herein by reference.
- 1. Field of the Invention
- The present invention is directed to a container and a method(s) for making and using a container. More particularly, the present invention is directed to a container that may change appearance in the presence of condensation on an exterior surface of the container.
- 2. Description of the Related Art
- Concession stands at sports stadiums, ballparks and other public venues represent a huge income source for many of these public facilities. The distribution of food and beverages can significantly increase the profits derived from such public facilities. However, a problem persists at concession stands with inventory control in which food and beverages that are not pre-packaged for the employees may be readily distributed to the public without recording the sale for the benefit of the concession stand owner.
- This problem is particularly acute in concession stand operations that rely on beverages poured on demand by the employees for the customer. Often variations in the volume of liquid poured varies from one container to the next container, such differences in volume and other factors render it very difficult for a concession stand owner to determine whether an employee is pocketing a sale for himself or providing free samples to the public.
- Currently preferred solutions for maintaining inventory control of beverages poured on demand utilize inventory control of the beverage containers and/or beverage fountains and taps that can dispense pre-measured amounts of the beverage. In this way, cup inventory control coupled with records of the number of pre-measured beverages dispensed can be used to determine losses in inventory. One drawback to this solution is the ability of employees to provide refills of cups already sold to the public. Employees can easily refill an existing cup and charge for the beverage without detection by concession stand management while pocketing the income for himself or providing a free refill to the customer.
- Solutions have been devised to stop inventory losses from refills provided by employees. One such solution, disclosed in U.S. Pat. No. 5,820,951 to Codell Industries, Inc. includes the use of thermo-chromic ink on the beverage container that changes colors when the temperature of a beverage container changes between predetermined hot and cold temperatures. Thus, pouring a cold beverage into a cold beverage container will result in a color change and pouring a hot beverage into a hot beverage container will result in a color change. This solution while fit for its intended purpose of providing some degree of inventory control has drawbacks as the color change is not permanent allowing for customers or others to reset the containers by simply adding a hot beverage to a container intended for a cold beverage or a cold beverage to a container intend for a hot beverage. Moreover two separate sets of cups need to be held in inventory, one for cold beverages and one for hot beverages. Furthermore, keeping track of color changes depending upon whether the drink is supposed hot or cold can lead to confusion by the concession stand employees as to whether the cup is already used. Finally, transportation of beverage containers is not usually provided in temperature-controlled environments. Thus, cold beverage containers shipped or stored in cold temperatures at or below the color-changing threshold may be rendered unfit for their intended purpose. Likewise, beverage containers shipped in hot temperatures at or above the color-changing threshold may also be rendered unfit for their intended purpose. Thus, the need exists for a way to provide automatically marked or identified cups that have been used for a sale of beverages from cups that are remaining in inventory.
- In some aspects, a container may include walls to form a receptacle, and a hydrochromic material associated with at least a portion of the peripheral wall. The hydrochromic material may be visible from the exterior of the container. The hydrochromic material may have a first appearance when in a dry form and a second appearance, different from the first appearance, when the hydrochromic material becomes hydrated.
- In accordance with some aspects, a method of making a container includes connecting a bottom wall with a peripheral side wall, providing a dry hydrochromic material having a first appearance that substantially matches an appearance of the peripheral side wall, and applying the dry hydrochromic material to at least a portion of the peripheral wall such that the hydrochromic material is visible from an exterior of the container. The hydrochromic material has a second appearance, different from the first appearance, when the hydrochromic material becomes hydrated.
- In some aspects, an inventory control method includes providing a container configured to contain a product, introducing a product into the container, and changing indicia on at least a portion of the container when condensation forms on the container. The indicia is visible from the exterior of the container.
- Other aspects, advantages and novel features of the invention will become more apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings wherein:
-
FIG. 1 is a side elevation view of an exemplary container having a first appearance in accordance with some aspects of the invention; -
FIG. 2 is a side elevation view of the container ofFIG. 1 having a second appearance in accordance with some aspects of the invention; -
FIG. 3 is a bottom view of an exemplary container in accordance with aspects of the invention; -
FIG. 4 is a cross-sectional view of the container ofFIG. 1 taken along line IV-IV; and -
FIG. 5 is a cross-sectional view of the container ofFIG. 2 taken along line V-V. - An exemplary embodiment of a
container 110 is shown inFIG. 1 . Thecontainer 110 may be described as including aperipheral wall 112 and abottom wall 114. Theperipheral wall 112 and thebottom wall 114 may be formed of plastic (including, but not limited to, PP=Polypropylene and PET=Polyester), paper, wax-coated paper, or other suitable materials for beverage containers. It will be appreciated by those skilled in the art, that typically for hot liquids, the container is formed from an insulated material such as a light, resilient polystyrene plastic sometimes referred to as Styrofoam™ or may include an insulated holder such as a ring or corrugated cardboard to insulate the holder's hand from the hot liquid; while cold beverages are typically served in a container of non-insulated material. Theperipheral wall 112 and thebottom wall 114 cooperate to define areceptacle 116. Thereceptacle 116 is configured to contain a beverage, for example, an alcoholic beverage (beer), soft drinks (soda or carbonated beverages), juice, coffee, hot chocolate, tea or water. - Advantageously, an exposed
surface 118 of theperipheral wall 112 includes a layer ofhydrochromic material 120 applied thereon to provide an intelligent packaging layer that reacts to the presence condensation on thelayer 120. - Preferably the hydrochromic material is produced in a printing ink form suitable for use in conventional printing systems. Furthermore, the hydrochromic material is such that it can be readily applied to any type of container material. The hydrochromic material to form
layer 120 may be applied to thesurface 118 by, for example, standard printing or silk screening processes known to those of ordinary skill in the art. In some aspects, thehydrochromic layer 120 may be applied to a label (not shown), which in turn is attached to the container. - In one preferred embodiment, the hydrochromic ink is preferably produced from comestible ingredients such as, but not limited to, a soy bean oil derivative.
- The
hydrochromic layer 120 has at least two different, visibly discernible appearances. By way of example as shown inFIG. 1 , thelayer 120 has a first appearance before a container is used to hold a liquid. The first appearance may be similar to that of the exposedsurface 118 such that thelayer 120 is minimally visible or opaque. Alternatively, thelayer 120 may be clearly visible. By hydrating thehydrochromic layer 120, for example, by causing condensation to form on the exposedsurface 118, thehydrochromic layer 120 changes from the first appearance to a second appearance, as shown inFIG. 2 . The first appearance may comprise, for example, a first color, and the second appearance may comprise, for example, a second color that is different than the first color. The condensation may be caused by introducing abeverage 122, for example, a chilled beverage, a heated beverage, or a room-temperature beverage, into thecontainer 110 to afill line 124. As shown inFIG. 2 , the portion of thehydrochromic layer 120 corresponding to the filled region may then change to the second appearance. - With the exception of hot drinks such as coffee, tea, or hot chocolate, most concession stand beverages, such as beer, juice and soft drinks, are typically served chilled with ice at temperatures between 36° and 43° F. The introduction of beverages into the
receptacle 116 causes condensation to form on the exposedsurface 118 and thehydrochromic layer 120, thereby changing thelayer 120 from the first appearance to the second appearance. Condensation forms under the principle that there are three temperatures one for the cup, one for the beverage and one for the ambient air. When combined by the introduction of a beverage into the container, the three temperatures of ambient air, container and beverage creates condensation that causes the change in the hydrochromic layer. Sufficient condensation may be formed each time the beverage is added whether it is hot or cold. Additionally, moisture may be transferred to the container from the palm of a person's hand or by wiping the container after each pour with a damp cloth. - In a preferred embodiment, the second appearance is maintained permanently, even when the
receptacle 116 is emptied and the condensation removed from the exposedsurface 118 and thelayer 120. - Accordingly, a purveyor of beverages, such as a concession stand manager, can monitor the
container 110 to determine whether thecontainer 110 is being filled for the first time or being refilled by visually observing the appearance of the exposedsurface 118 and thehydrochromic layer 120. When thelayer 120 is applied to a large portion of the exposedsurface 118, as shown inFIG. 1 , the color of thelayer 120 can be viewed from a distance thereby permitting even the use of security camera's to monitor unauthorized refills. Even if thelayer 120 covers only a portion of the exposedsurface 118 as shown in theFIGS. 1 and 2 , it will be appreciated by those skilled in the art that thelayer 120 may cover the entire exposedsurface 118 or a smaller area as needed for visual recognition of thelayer 120. - It will further be appreciated by those skilled in the art that by applying the
hydrochromic layer 120 using standard printing processes thelayer 120 may be arranged in any predetermined form such as a message, for example, “NO REFILLS”, or a predetermined design. The design may simply be an indication to concession workers that the container has been used and is not to be refilled. Alternatively or additionally, thehydrochromic layer 120 may be arranged in a predetermined form of an advertisement, for example, a logo or design. It should also be appreciated that the first appearance and/or the second appearance of thehydrochromic layer 120 may be multi-colored. - In one embodiment, the container 310 (
FIG. 3 .) includes a layer ofhydrochromic material 320 arranged in a machine-readable form or pattern 326, for example, a barcode. A machine reader such as barcode scanner (not shown) may be configured to sense the pattern 326 with thelayer 320 in first and second appearances. Upon sensing the presence of thelayer 320 in the first appearance, the scanner may send a signal to a processor (not shown) such that the processor may determine that an unused container is present and that a beverage may be dispensed. Upon sensing the presence of thelayer 320 in the second appearance, the scanner may send a signal to the processor such that the processor may determine that a previously used container is present and that a beverage should not be dispensed. A scanner of the type suitable for this purpose is disclosed in U.S. Pat. No. 5,820,951. - It should be noted that other machine-readable configurations might be implemented with the hydrochromic ink without departing from the spirit of the invention. For example, the exposed surface of the
container 310 may include a light reflective material or barcode printed using a non-hydrochromic ink. The hydrochromic ink may be of a form that varies in opaqueness. That is it transitions from or into an opaque form to or from non-opaque image or pattern thereby blocking the reflective material or barcode image when the hydrochromic ink is in an opaque form. In the case of using reflective material, a standard electric eye configuration adapted to sense the presence or absence of the reflective material maybe used to sense whether the container may be refilled. - In an alternative form of this embodiment, the hydrochromic layer may be printed with a machine-readable unique identifier for each cup or a series of cups so that a machine reader can track the number of refills used for this cup. Such a configuration is particularly desirable where the uses of novelty cups are used. Often the novelty cups are sold at a much higher price than the cost of a normal beverage; however, consumers are often offered refills in the novelty cups at a discounted price. By employing a machine-readable unique identifier, concession stand operators can track or even limit the number of refills available per cup. Alternatively where each unique identifier refers to a series of cups, different series can be released on different days, at different events or for different beverages, such as domestic or imported beer. Thus, a concession operator may be able to limit the refills only to cups in series that is purchased that day, for that event or for that beverage type. It will be appreciated by those skilled in the art that the number of possible uses for a unique identifier on a cup may be used for a number of different configurations. Thus the examples provided above are intended to be exemplary and not limiting to such uses of a unique identifier.
- With such arrangements, unauthorized refilling of the
containers 310 can be prohibited. At the same time, attempted refilling of containers can be made known to the establishment by identifying and/or recording the same through the processor. - Referring now to
FIGS. 4 and 5 , a layer ofhydrochromic material 420 may be applied to afirst surface 432 of asubstrate 430. Thesubstrate 430 may be, for example, a plastic, a paper, or a wax-coated material. Thesubstrate 430 may be shapeable into, for example, a container, such as a container configured to contain a beverage. The layer ofhydrochromic material 420 may include one ormore coloring compositions 422, for example, pigments and/or masking agents and a bonding resin, printing ink, and/orfixation agent 424. - The bonding resin, printing ink, or
fixation agent 424 is selected such that the resin, ink, oragent 424 may bond the one ormore coloring compositions 422 to thesubstrate 430 via a standard flexographic or screen printing process known to persons of ordinary skill in the art. The bonding resin, printing ink, andfixation agent 424 is also selected such that the resin, ink, oragent 424 can absorb moisture to hydrate the one ormore coloring compositions 422, for example, caused by condensation on thesubstrate 430, but can also retain the hydrated coloring compositions with minimal bleeding. The one ormore coloring compositions 422 may include two or more coloring compositions such that an initial, non-hydrated appearance of the coloring compositions masks a final, hydrated appearance of the one or more coloring compositions. The initial and final appearances may be colors, and the initial and/or final appearance may include one or more colors. The one ormore coloring compositions 422 may be applied in a dry form, for example, powder or crystal. - As shown in
FIG. 5 , when a liquid 440, for example, a chilled beverage, comes into contact with aregion 436 of asecond surface 434 of thesubstrate 430, condensation developing on thefirst surface 432 may be absorbed by the bonding resin, fixation agent, and/orprinting ink 424 and the one ormore coloring compositions 422 in acorresponding region 438 of thefirst surface 432. Thesecond surface 434 is on the opposite side of thesubstrate 430 from thefirst surface 432. As a result, the one ormore coloring compositions 422 may change from the initial appearance to a final appearance. For example, the initial appearance of thehydrochromic material 420 may be a yellow color. Upon hydration, a red coloring may mix with the yellow, thus changing the appearance of thehydrochromic layer 420 to an orange color. - With this arrangement, the hydrochromic layer may change from the first appearance, shown in
FIG. 4 , to the second appearance, shown inFIG. 5 , to give a concession worker a visual indication that the container formed of thesubstrate 430 was previously filled with a beverage, thus helping to prevent unauthorized refills. - In the presently preferred embodiment of this invention, the transition of the hydrochromic ink when it is hydrated is intended to be permanent, thus drying of the container surface will not cause the hydrochromic material to transition back into its dry state.
- Furthermore, it will be appreciated that the cups utilizing a hydrochromic material are not subject to temperature fluctuations during transport and storage. While exposure to humidity may affect the hydrochromic material, exposure to humidity during transport and storage of the containers may be controlled by simply packaging the container in plastic bags which is generally already done today for sanitary considerations. Furthermore for novelty cups or other odd shaped containers, a removable layer (not shown) may be included to overlie to the hydrochromic material to protect it from humidity during transport and storage. This layer would then be removed at the time of purchase to expose the hydrochromic material to condensation.
- In another preferred embodiment, the hydrochromic material is used as a visual indicator to communicate that the sanitary condition of the container has been maintained during transport and storage prior to use by the consumer. Often QSR's (Quick Service Restaurants) and convenience stores put containers out or provide self serve dispensers for their customers. The container area can get messy and either store employees or customers may unknowingly return containers that have already received a beverage to the stack of clean containers. In this instance the hydrochromic layer is used to indicate that the container has not been stored or transported under sanitary conditions or has already received a beverage. In this way customers and employees may then dispose of the container without using it.
- It will be apparent to those skilled in the art that various modifications and variations can be made to the container and method of the present disclosure without departing from the scope of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only.
