FIELD OF THE INVENTION
The present invention relates generally to beverage coolers and to re-freezable cooler inserts which are designed and configured to receive, transport, and cool beverage containers.
BACKGROUND OF THE INVENTION
There is multitude of different types of coolers and cooler inserts for keeping food and beverages cool, or warm, until such items are consumed. These coolers and inserts come in a wide variety of shapes and sizes. Some coolers have hard outer and inner shells, some have soft outer and inner shells, and some are simply have a nylon fabric serving as the covering for the cooler itself or for individual packages of refrigerant material. Similarly, cooler inserts come in variety of shapes and sizes. Some cooler inserts have a hard outer shell, some cooler inserts package their refrigerant material inside a soft flexible plastic covering, and some require the user to fill the cooler insert with a refrigerant material of some kind, generally water, before use.
In order to maintain the temperature within the beverage/food compartment of a cooler, some type of insulating material is disposed between the outer and the inner shells of the cooler. One of the most common insulating materials used in these types of coolers is a high density foam material which is generally adequate at maintaining a cool or warm temperature within the cooler. Some of the most common means to cool the interior of most generic coolers include blocks of ices, cubed ice, crushed ice, cold water, and cooled or frozen individual packages of refrigerant. These and other methods utilized to cool the interior of a cooler, as well as the use of some cooler inserts, often present undesirable results.
The use of ice blocks or ice cubes as a coolant, as well as the use of hard-shelled cooler inserts, limits the number and manner in which beverages or food items can be arranged within the cooler resulting in an inefficient use of the cooler's interior space. Although crushed ice can be manipulated to some extent within a cooler's interior, there remains space between the crushed ice particles which cannot be used for more efficient packing of beverages or food. Although the use of cooler inserts with refrigerant packaged in a soft plastic covering provides some limited flexibility with regard to the interior space of a cooler, the positioning of these cooler inserts may shift during transportation of the cooler. Regardless of which form of ice is used as a coolant, as the ice melts undesired consequences can occur. As ice melts, the position and arrangement of the beverages or food items within the cooler will shift in the resulting ice water. Retrieving beverages by hand from melted ice water can be unpleasant due to the cold temperature of the water as well as its wetness if a person prefers or needs to maintain dry hands. The possibility of contaminating food items and beverages also exits with melted ice water should the water be able to get inside the packaging of such items. If using ice or cold water as a refrigerant, it can become contaminated by dirt or other debris which in turn may contaminate the beverages or food items within the cooler. Also, depending on the nature of the contaminated ice, its disposal may have an undesired environmental impact or health risk. Additionally, the contaminated ice or cold water will need to be replaced which may or may not be possible if a source for more ice or cold water is not available. Furthermore, often when ice is used as a coolant it will be necessary to purchase new ice once the ice has melted and discarded. The use of ice or cold water as a refrigerant will also result in the necessity of the cooler needing to be thoroughly cleaned after each use. The aforementioned issues related to the use of ice and cold water as a refrigerant also exits with the refrigerants used for cooler inserts. For example, in the event the integrity of the cooler insert exterior become damaged and allow its refrigerant to leak into a cooler's interior, the items within the cooler may become spoiled or contaminated, disposal of the refrigerant may contaminate the environment and the person using the cooler, and a thorough cleaning of the cooler becomes necessary.
Accordingly, there remains room for improvement and variation within the art.

A cooler insert 10 for cooling beverages or food items is illustrated in FIGS. 1 to 7. In accordance with a preferred embodiment of the present invention, a cooler insert 10 is illustrated in FIGS. 1 to 7 comprising a hexahedrical container 11 which includes a plurality of cylindrical deep beverage receptacles 21 extending from a top side 13 of the hexahedrical container 11 into a hollow interior 41 of the hexahedrical container 11. As used herein, the term “hexahedrical” container is defined and intended as a polyhedron having six sides. The hollow interior 41 of the hexahedrical container 11 contains a refrigerant material 42 to cool a beverage container 51 placed within the deep beverage receptacles 21 or any food items place adjacent to, or in the proximity of, the exterior surface 12 of the hexahedrical container 11. Additionally, the hexahedrical container 11 includes a bottom side 14 with a plurality of shallow beverage receptacles 31 extending upward into the hollow interior 41 of the hexahedrical container 11 to facilitate stacking multiple cooler inserts having one or more beverage containers 51 within the deep beverage receptacles 21, and to provide additional cooling to any beverage containers placed in a lower cooler insert 10.
Now specifically referring to FIGS. 1, 3, and 4, one embodiment of a cooler insert 10 is shown comprising a hexahedrical container 11 having an exterior surface 12 including a top side 13 and a bottom side 14. Additionally, the hexahedrical container 11 includes a plurality of deep beverage receptacles 21 arranged in a parallel configuration and extend from the top side 13 of the exterior surface 12. Referring to FIG. 4, the deep beverage receptacles 21 also have a cylindrically shaped side 22 which emanates downward to a bottom 23. Now referring to FIGS. 2, 3, and 4, the hexahedrical container 11 also includes a plurality of shallow beverage receptacles 31 extending from the bottom side 14 of the exterior surface 12. Referring to FIG. 4, the shallow beverage receptacles 31 have a cylindrically shaped side 32 emanating upward to a top 33. As shown in FIGS. 3, 4, and 5, the shallow beverage receptacles 31 located on the bottom side 14 of the exterior surface 12 of the hexahedrical container 11 are co-axially aligned with the deep beverage receptacles 21 located on the top side 13 of the exterior surface 12 of the hexahedrical container 11. In similar fashion, the diameters of the deep beverage receptacles 21 and the shallow beverage receptacles 31 are equal in a preferred embodiment of the present invention. Now referring to FIGS. 1 and 4, the hexahedrical container 11 also includes a hollow interior 41 that is configured to provide a fluid-tight reservoir. The hollow interior 41 is surrounded by the exterior surface 12 of the hexahedrical container 11 and the plurality of cylindrically shaped sides 22, 32 of the deep beverage receptacles 21 and the shallow beverage receptacles 31, as well as the bottom 23 of the deep beverage receptacle 21 and the top 33 of the shallow beverage receptacles 31. Additionally, now referring to FIGS. 1 and 3, a refrigerant material is disposed within the hollow interior 41 of the hexahedrical container 11 and therefore enables the cooler insert 10 to cool not only beverage containers within and in communication with the deep beverage receptacles 21 and the shallow beverage receptacles 31, but also others items in direct communication with, or adjacent to, the exterior surface 11 of the cooler insert.
As shown in FIGS. 1, 3, 5, 6, and 7, in one embodiment of the present invention each of the deep beverage receptacles 21 on the top side 13 of the hexahedrical container 11 are designed and configured to enclose a substantial portion of a beverage container body 53 such that most of the beverage container 51 is exposed to the cooling effect of the refrigerant material 42 housed within the hollow interior 41 of the hexahedrical container 11. The beverage container 51 has a top portion 52 that is not enclosed by the deep beverage receptacle 21 which permits easy access to the beverage container for removal from the deep beverage receptacle 21.
A preferred embodiment of the present invention is illustrated in FIGS. 2, 3, 4, and 5, wherein each of the shallow beverage receptacles 31 of the hexahedrical container 11 has a depth sufficient to at least partially enclose the top portion 52 of an inserted beverage container 51 when a first cooler insert is stacked on top of a second cooler insert containing one or more beverage containers 51, wherein the first cooler insert 10 may or may not contain one or more beverage containers.
In a preferred embodiment of the present invention a translucent gel refrigerant material 42 as shown in FIG. 3 is disposed within the hollow interior 41 of the hexahedrical container 11, and is used to cool the beverage container 51 placed within the deep beverage receptacle 21. Non-water, or gel refrigerants, or such other similar refrigerant material possessing the necessary heat or cold retaining properties, can be used in the present invention to keep the content of beverage containers cold.
As illustrated in FIGS. 1 and 2, additional embodiments of the present invention may include an exterior surface 12 for the hexahedrical container 11 which is manufactured from a heat conductive polymer, such as but not limited to, polyethylene, polypropylene, styrene, acrylonitrile butadiene styrene, acetal, K resin styrene butadiene copolymers, Nylon 6/6, polyethylene terephthalate, and thermos-plastic elastomers.
Referring to FIG. 3, a preferred embodiment of the present invention includes a hexahedrical container 11 having a transparent exterior surface and a translucent gel refrigerant material 42 disposed within the hollow interior of the hexahedrical container. A plurality of small clear, or translucent, plastic particles 43 are dispersed and suspended within the translucent gel refrigerant. It is intended that the plastic particles appear as ice crystals floating within the translucent gel refrigerant.
In another embodiment of the present invention, referring to FIG. 6, the hexahedrical container 11 has a shape which conforms to the interior shape of a small cooler 61.
Referring to FIGS. 1 and 2, in still another embodiment of the present invention the configuration of exterior surface 12 includes two parallel rows of three deep beverage receptacles 21 on the top side 13 of the hexahedrical container 11 and two parallel rows of three shallow beverage receptacles 31 on the bottom side 14 of the hexahedrical container 11 with the deep beverage receptacles 21 being co-axially aligned with the shallow beverage receptacles 31. This configuration and packaging for six-pack beverages is often used in the retail sale of six-packs of bottled water, as well as cans of soda, beer, and juice. The bottles and cans for such six-pack beverages can often be placed directly into the cooler insert without the need to first remove the plastic collar used to by the vendors of these beverages for packaging and distribution.
Additional embodiments of the present invention include the hexahedrical container being designed and configured to enclose various of kinds of beverage containers such as beer cans, soda cans, water bottles, juice cans, milk cartons, and other beverage containers. The size, shape, and depth of the deep beverage receptacles on the top side of the cooler insert, as well as the size, shape, and depth of the shallow beverage receptacles on the bottom side of the cooler insert can be configured as needed to accommodate the specific shape and size for different kinds of beverage containers.
An additional embodiment of the present invention includes a hexahedrical container in which the depth of the beverage receptacles located on the top side of the hexahedrical container is the same as the depth for the beverage receptacles located on the bottom of the hexahedrical container. This configuration of the cooler insert eliminates receptacles on a specific side of the cooler insert as being designated to receive either the top portion or the bottom portion of a beverage container. Additionally, the orientation of such an embodiment of a cooler insert is not a factor when stacking multiple cooler inserts with beverage containers on top of one another.
To use the present invention the cooler insert is placed into a freezer, or other cold environment, for at least one hour prior to use to adequately decrease the temperature of the gel refrigerant housed within the hollow interior of the cooler insert. Once gel refrigerant within the cooler insert has had sufficient time to cool or freeze, appropriate sized beverage containers are placed within the deep beverage receptacles until the beverage is removed by the user for consumption of the beverage container contents. A single cooler insert can be use by itself when cooling a small number of beverage containers. Or, multiple cooler inserts can be used when cooling a larger number of beverage containers. When using multiple cooler inserts for larger numbers of beverage containers, the cooler inserts can be stacked on top of each other to maximize cooling efficiency. Additionally, referring to FIG. 6, the single cooler insert can be designed and configured to fit inside a small cooler to maximize cooling efficiency and to facilitate transportation of the cooler insert and its beverage container contents. Likewise, referring to FIG. 7, multiple cooler inserts can be designed and configured to fit inside a large cooler to maximize cooling efficiency and to facilitate transportation of the cooler inserts and their beverage containers.
The previous versions of the present invention have many advantages including the ability for the cooler insert to be used as a single cooler insert, together with multiple cooler inserts if desired or necessary, or alone as a stand-alone cooler. When multiple cooler inserts are used, the design, configuration, and inter-cooperation between the deep beverage receptacles and the shallow beverage receptacles allow for the stable stacking of the cooler inserts. Additionally, when the cooler inserts are used in a stacked configuration, the beverage containers in the lower beverage receptacles receive maximum cooling since very little of the beverage container's surface is not enclosed within a beverage receptacle. Additionally, the cooler insert is environmentally friendly since its refrigerant material is housed within the fluid-tight hexahedrical container that is manufactured from durable materials. As such, there is no need to replace the refrigerant material, nor is there a possibility of pollution as there may be with other systems in which the refrigerant material can be lost, or must be replaced after use, such as certain non-water refrigerants, as well as contaminated ice or water, that may pollute the ground. The cooler insert also requires no, or very little, maintenance due to its design and the materials from which it is manufactured. In the event the cooler insert becomes dirty, it can be easily cleaned and rinsed with water in preparation of its return to use. Therefore, the cooler insert can be used repeated over an indefinite period of time. However, when ice is used as a refrigerant and becomes contaminated with dirt or debris, the ice must be discarded and replaced. When the cooler insert is used in its six-pack configuration, there is no need to remove the plastic packaging ring which is often used in the retail sales and distribution of six-packs of beverages such as soda, beer, and bottled water until a beverage container is removed from the cooler insert. Since the refrigerant material is sealed with the fluid-tight interior of the cooler insert, there is no need to purchase ice or other refrigerant material. The cooler insert is simply placed in freezer or other cold environment for at least one hour prior to use to allow sufficient time for the gel refrigerant to cool or freeze. Additionally, since ice is not used as the refrigerant material, there is no opportunity for leaks or items getting wetting un-necessarily. The cooler insert is also adaptable for use with existing hard-shell coolers of various sizes and kinds, as well as coolers constructed from nylon fabric materials. Unlike traditional coolers, the present invention is free from associated water leaks or fabric tears. Additionally, not only does the cooler insert cool beverage containers within its beverage receptacles, it also provides cooling temperatures to other items that are otherwise adjacent to the cooler insert's exterior surface. The gel refrigerant within the cooler insert's hollow interior that surrounds the cooler insert's beverage receptacles is also in direct communication with exterior surfaces of the cooler insert which in turn provides additional cooling surfaces which can be utilized. The cooler insert can also be designed, configured, and manufactured to accommodate beverage containers having a variety of shapes and sizes.

The words used are words of description rather than of limitation. It is to be understood that changes and variations may be made by those of ordinary skill in the art without departing from the spirit or the scope of the present invention. In addition, it should be understood that aspects of the various embodiments may be interchanged, either in whole, or in part. Therefore, the spirit and scope of the invention should not be limited to the description of the preferred versions contained herein.
