DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 10 thereof, a new container insulating device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 10, the container insulating and cooling system 10 generally comprises a covering 12 for a container 14 to insulate the container 14 from changes in a desired temperature as well as specifically remove heat from the container 14. However, the system 10, as will be discussed below, may also be used to add heat to the container 14. Depending on the configuration of the system 10, the container 12 may be any container 14 and in particularly one used for holding beverages such as bottles, cans and the like. However, the system 10 may be used with virtually any other container 14 where the user would like the container 14 to be retained in a cold state, such as kegs, bottles, cups, glassware, jugs, growlers or other containers. The container 14, however, may be particularly suited to the system 10 and include a peripheral wall 16 having a plurality of indentations 18 therein for reasons which will be described below.
The covering 12 includes a perimeter wall 20 that has an upper edge 22 and a lower edge 24. The perimeter wall 20 has an inner surface 26 and an outer surface 28. The upper edge 22 defines an opening 30 extending into an area bounded by the perimeter wall 20. A bottom wall 32 may be attached to the lower edge 24 of the perimeter wall. As shown in FIGS. 2 and 3, the bottom wall 32 may only be partially attached to the lower edge 24 to allow for folding of the bottom wall 32 during storage of the covering 12. However, the bottom wall 32 may be provided that co-extensive with the lower edge 24.
The perimeter wall 20 comprises a flexible material which, more particularly, may comprise a resiliently stretchable material. This will allow the perimeter wall 20 to conform to the size and shape of the container 14 on which it is being positioned. Alternate variations may be utilized including the usage of a plurality of sections of the perimeter wall 20 which would include non-flexible sections and resiliently stretchable sections. Another variation may include the perimeter wall having break therein extending through the upper 22 and lower 24 edges and a closure used to releasably close the break. The closure may include a hook and loop closure, zipper, snaps and the like.
The perimeter wall 20 may include at least one layer 34 comprising an insulating material. The perimeter wall 20 may include a plurality of layers 34, 36 wherein one layer 36 is provided that is water resistant to prevent fluids from wicking through the perimeter wall 20. The water resistant layer 36 and the insulating layer 34 may comprise the same layer. Insulating and water resistant properties of the perimeter wall 20 will ensure that a user of the system 10 will be able to comfortable grip the covering 12.
The inner surface 26 of the perimeter wall includes one or more cells 38. The cells 38 may be positioned within in an innermost layer of the perimeter wall 20 or simply attached to the inner surface 26. Each of the cells 26 is comprised of a water permeable and flexible material to allow water to flow into the cells 26 and therefore the cells 26 may be comprised of a mesh material. Each of the cells 38 has an absorbent material 40 therein. The absorbent material 40 expands when hydrated to such that the absorbent material fills 40 and expands the cells 38. The absorbent material 40 may comprise any material that readily absorbs water and increases in size several times. One class of such materials are super absorbent polymers which are known to increase their size by greater than 50 times. Other materials, such as sodium bentonite may be used which swell at approximately 12-15 times their original size. Additional materials such as food starches may also be used due to their expansion properties. Materials such as sodium bentonite may have some advantages for reusability since they may be dehydrated easily and thereafter be hydrated again. Essentially, any material may be used which absorbs large quantities of water and increase size at least 300%. It should be noted that a single cell 38 may be provided which covers a portion of inner surface 26 or covers the entirety of the inner surface 26.
Should the container 14 include indentations 18, the cells 38 will be positioned so that each is aligned with one of the indentations 18. Though the indentations 18 and cells 38 are each shown as elongated vertically, they may be horizontally orientated instead or have any suitable geometric shape which may include decorative shapes. The cells 38 expand into an aligned one of the indentations 18 such that the perimeter wall 20 is secured to the container 14. This prevents the covering 12 from rotation with respect to the container 14. Alternatively, or in addition to the combination of the cells 38 and indentations 18, adhesive 42 may be positioned on the inner surface 26 to adhesively secure the inner surface 26 to the container 14. The adhesive 42 may be positioned at one or more points on the inner surface 26 and may be positioned between the cells 38 as shown in FIG. 10.
In use, the covering 12 is placed in water 44 so that the absorbent material absorbs the water and expands which in turn expands the cells. The cells 38, by expanding will push outwardly and frictionally engage the container 12 to retain the covering 12 on the container 14. However, the covering 12, before being placed on the container 14, may be placed in an environment that freezes the water 44 in the cells 38. Thus frozen, the cells 38 when placed the container 14, will chill the container 14 or retain the container 14 in a chilled condition. After hydration of the absorbent material, the covering 12 may be placed on the container 14 and the container 14 and covering 12 each placed in a cooled environment, such as a refrigerator, so that the absorbent material and the container 14 are both cooled. Thereafter, when the container 14 is removed from the refrigerator, the covering 12 will help retain the container 14 in a cooled condition. Because the perimeter wall 16 is stretchable, the covering 12 will readily conform to the shape of the container 14 on which it is positioned.
Furthermore, it should be understood that the absorbent material 40 may instead be filled with heated water or hydrated and then heated to retain the container 14 in a warmed condition. Moreover, one or more of the coverings 12 may be placed in water at a selected temperature and to retain a container 14 at that selected temperature. For example, a plurality of coverings 12 may be placed in an ice water bath and then removed as needed to receive a container to cool the container. The covering 12 may be utilized as a label wrapper for the container 14 that will also effectively retain the container at the selected temperature. Thus, the covering 12 may be hydrated after it has already received the container 14 and thereafter hydrated and cooled or hydrated with water of a selected temperature.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
