In the description that follows, like parts are marked throughout the specification and drawings with the same reference numerals. The drawing figures might not be to scale and certain components can be shown in generalized or schematic form and identified by commercial designations in the interest of clarity and conciseness.

In accordance with the present disclosure, a reusable cooler for distribution of beverage containers is provided that eliminates the need for ice to be used to maintain the beverage containers at a cold temperature. The present disclosure includes a number of exemplary embodiments, such as a first embodiment that is stackable, has open sides with drop-in thermal packs, and which has a digital temperature sensor and an associated display. A second embodiment is soft sided and foldable and also has a digital temperature sensor and associated display. A third embodiment is closed-sided, filled with a reusable thermal solution and has a digital temperature sensor and associated display. In these exemplary embodiments, the digital temperature sensor and associated display can be powered by a solar photovoltaic array, a battery or can be a passive type indicator that uses color changing materials or other suitable passive devices. The dimensions of the reusable cooler can be optimized for predetermined products, such as cans, bottles, long necks or other suitable containers. Interior spacers can also be provided, to improve the ability of the reusable cooler to maintain cold beverage temperatures. A replaceable logo cover or pocket can also be used, to allow the exterior of the reusable cooler to be customized for predetermined sporting events.

FIG. 1 is a diagram of a cooler 100 in accordance with an exemplary embodiment of the present disclosure. Cooler 100 has hard sides and corresponding slots 104, 106, 106 and 108 in each side to hold thermal packs (not explicitly shown). The remainder of each sidewall of cooler 100 can be filled with insulation. The thermal packs are typically frozen, but could alternatively be heated. Cooler 100 is optimized for maintaining the temperature of beverages that have already been cooled or heated, and as a result does not require ice to be used to cool beverages down or other internal temperature adjustment materials.

The term “thermal pack” as used herein refers to a suitable package containing a suitable substance (solid, liquid, gas or gel) with thermal properties that allow it to act as a heat source or heat sink for packaged food and beverages. In one exemplary embodiment, the thermal packs can be stored in a freezer or cooler prior to use, then inserted into cooler 100 for use and removed from cooler 100 after use. Thermal packs can be layered in rows, disposed between individual food or beverage containers or layers or food or beverage containers, or otherwise used in place of ice.

In addition to slots 102, 104, 106 and 108, cooler 100 includes vents in the interior sides (not explicitly shown) to improve heat transfer from the beverage containers to the thermal packs. A photovoltaic array 122 is disposed on flexible insulated cover, and is operatively coupled to digital display and thermocouple 102, which is used to display the interior temperature of cooler 100. Additional digital displays and thermocouples can also or alternatively be provided on other sides of cooler 100. In addition, a removable inner floor panel is used to store additional thermal packs.

Cooler 100 is stackable, and can be filled and stored in a walk in freezer for subsequent use. Cooler 100 can be formed by blow molding or other suitable processes, and can be customized with colors, patterns, logos, advertising or other designs, which can be applied after the molding process, which can be removable or which can otherwise be provided. In one exemplary embodiment, digital display and thermocouple 102 can also or alternatively provide a digital message, advertising, or other suitable data.

Cooler 100 can include openings 112 and 114 for handles, support straps or other suitable devices to allow a user to easily carry cooler 100, such as to sell beverages in a sports arena or other suitable locations.

In operation, cooler 100 is prepared for use in food or beverage sales by loading frozen thermal packs into slots 104, 106, 106 and 108, and then loading chilled food or beverage containers into the interior of cooler 100. Alternatively, heated food and beverages and heated thermal packs can be used where suitable. Cooler 100 can then be stored in a walk-in cooler and stacked with other instances of cooler 100. A user then retrieves a stocked and chilled cooler 100, and can distribute chilled or heated foods and beverages to others, such as during a sporting event, a musical event or other suitable events.

FIG. 2 is a cut-away view 200 of a cooler 100 in accordance with an exemplary embodiment of the present disclosure. Cut-away view 200 shows thermal pack vents 202, 204 and 206 that improve the heat transfer capability between thermal packs 208A and 208B, which are disposed inside of the walls of cooler 100, and food or beverages stored in cooler 100. As can be seen in cut-away view 200, the thermal packs 208A and 208B are inserted into the walls of cooler 100 until they are below the location of opening 112, so as not to interfere with handling of cooler 100.

FIG. 3 is a cut-away view 300 of a cooler 100 in accordance with an exemplary embodiment of the present disclosure. Cut-away view 300 shows thermal pack vents 302, 304 and 306 that improve the heat transfer capability between thermal packs 208A, 208B and 208C, which are disposed inside of the walls of cooler 100, and food or beverages stored in cooler 100. As can be seen in cut-away view 300, the thermal packs 208A, 208B and 208C are inserted into the walls of cooler 100.

FIG. 4 is a diagram of cooler 400 in accordance with an exemplary embodiment of the present disclosure. Cooler 400 is covered with a soft flexible material on each sides, on the top and on the bottom, with wall and floor cavities that are sealed and filled with a suitable thermal solution (solid, liquid, gas or gel refrigerant), which allows cooler 400 to be stored in a freezer or other suitable locations for a predetermined period of time, until the thermal solution has solidified or otherwise reached a predetermined temperature. In one exemplary embodiment, cooler 400 can be stored in a folded configuration, then filled with food or beverage containers while it is unfrozen and placed in a freezer until it reaches a predetermined temperature, as indicated by digital display and thermocouple 102. In this manner, cooler 400 occupies less space until it is being prepared for use, and remains flexible until it is frozen in preparation for use, at which point it becomes easier to handle for the purpose of beverage sales.

FIG. 5 is a diagram of cooler 500 in accordance with an exemplary embodiment of the present disclosure. Cooler 500 has wall and floor cavities that are sealed and filled with a suitable thermal solution (solid, liquid, gas or gel refrigerant), which allows cooler 500 to be stored in a freezer or other suitable locations for a predetermined period of time, until the thermal solution has solidified or otherwise reached a predetermined temperature. In one exemplary embodiment, cooler 500 can be filled with food or beverage containers while it is unfrozen and then placed in a freezer until it reaches a predetermined temperature, as indicated by digital display and thermocouple 102.
