FIGS. 1 , 3) are fixedly disposed on opposite sides of upper frame 3 to permit easy carrying ofcontainer 10 when inflated and loaded with articles. In addition, a typical latch mechanism 58 (FIG. 1 ) is provided to releasablysecure lid 44 toupper frame 32 whenlid 44 is pivoted to its down, or closed, position. Additionally, a combination air intake and air outflow nozzle 60 (FIGS. 1 , 3), as is known in the art, extends through anopening 62 inlower frame 50, and has one end providing access intoair chambers 20, 28, which are all pneumatically interconnected. - To inflate the
air chambers 20, 28 of cooler 10,nozzle 60 is attached to a source of pressurized air as is known in the art, and the pressurized air is introduced intoair chambers 20, 28, thus inflating the cooler 10 into the shape shown inFIG. 1 . The source of air pressure is removed when theair chambers 20, 28 are fully inflated. To deflate theair chambers 20, 28, thenozzle 60 is manipulated, as is known in the art, to allow air under pressure to escape the air chambers, thereby deflating theair chambers 20, 28 and collapsing cooler 10. - If desired, a drain hose (not shown) extending from the bottom 22 of compartment 11 to the outside of
lower frame 50 may be provided to remove water or other liquids that may accumulate in cooler 10 during use. - In an embodiment, the cooler 10 of the present invention includes a collapsible reinforcing retainer generally designated by the numeral 64 (
FIGS. 5 , 6, 7) that may be either securely fastened or removably inserted throughopening 34 and opened inside compartment 11. Referring toFIGS. 5 , 6 and 7, the reinforcingretainer 64 of the disclosed embodiment comprises anupper rim 66 of rigid material such as ABS plastic, wire or equivalent material and mimicks the shape of the upper extent of the compartment 11.Retainer 64 also comprises alower rim 68 also composed of a rigid material such as ABS plastic, wire or equivalent. Lower rim 68 mimics the shape of the outer extent ofbottom portion 22 of the inside compartment 11 of cooler 10. - Extending between
rims elements 70, each having a central pivotable andreleasable locking mechanism 72 that is known to those skilled in the art. As an example, atypical locking mechanism 72 will automatically lock the upper and lower parts of stiffeningelements 70 as shown inFIG. 7 when the two parts reach a co-planar position. To unlock stiffeningelements 70, slight finger pressure is applied to the outside of eachlocking mechanism 72, forcing themechanism 72 to allow relative pivotal movement of the two parts of stiffeningelements 70, as shown inFIG. 6 . Continued pivotal movement between the two parts of each stiffeningelement 70 will result inrims FIG. 5 . - It is clear that when reinforcing
retainer 64 is inserted into compartment 11 of cooler 10, and the retainer is moved to its position shown inFIG. 7 , that theretainer 64 will supplement the strength and rigidity of sidewalls 12 of the cooler whenair chambers 20, 28 are fully inflated. - To begin use of the cooler 10, a source of air pressure is applied to nozzle 60 (
FIGS. 1 , 3) to fully inflateair chambers 20, 28. When fully inflated, the air chambers expand and cooler 10 will assume the shape and configuration shown inFIGS. 1 and 2 . If reinforcingretainer 64 is already inserted into compartment 11, and if theupper rim 66 andlower rim 68 are attached to an upper portion ofpanels 16 and to the outer edges ofbottom 22 ofcontainer 10 respectively, theretainer 64 will expand vertically from the position shown inFIG. 5 , through the position shown inFIG. 6 , and end up in the position shown inFIG. 7 , with stiffeningelements 10 automatically engaging into a locked position, as explained above. Also, as air chambers are filled with air,upper frame 32 moves vertically away fromlower frame 50, as seen inFIG. 1 . In the position shown inFIGS. 1 and 2 , the cooler 10 is ready to be used by inserting and/or removing beverage, food and coolant items into or out of compartment 11 throughopening 34 whenlid 44 is opened.Handles 56 can be used to manually transport the cooler 10 to its desired location. - After the cooler 10 has been utilized, the present invention provides a novel enclosure for storage and transportation of the
container 10. After removal of all beverages, food and coolant items from compartment 11,nozzle 60 is manipulated to release all of the air fromair chambers 20, 28. As the removal of air continues,upper frame 32 moves lower asflexible sidewalls 12 collapse, until thelower lip 74 ofouter flange 38 of theupper frame 32 abutsupper lip 76 offlange 54 oflower frame 50, as illustrated inFIGS. 3 and 4 . Referring toFIG. 4 , as theupper frame 32 contactslower frame 50, thesidewalls 12 ofcontainer 10 fold into cavity 78 (FIG. 4 ) formed by the first and second cavities ofupper frame 32 andlower frame 50, respectively. - In the embodiment wherein reinforcing
retainer 64 is inserted into or in place in compartment 11 during use of the inflated container, as air is removed fromair chambers 20, 28, finger pressure is applied to the outer side of locking mechanism 72 (FIGS. 5 , 6, 7) to pivot stiffeningelements 70 into the unlocked position shown inFIG. 6 . Continued deflation ofcontainer 10 and the corresponding movement ofupper frame 32 towards contact withlower frame 50 results in reinforcingretainer 64 completely collapsing into the position shown inFIG. 5 while remaining inside the foldedsidewalls 12 and inside cavity 78 (FIG. 4 ). Thus, theflexible sidewalls 12 ofcontainer 10 and the collapsible reinforcingretainer 64 are secured insidecavity 78 automatically when air is removed fromair chambers 20, 28. - Once
upper frame 32 contactslower frame 50 as seen inFIGS. 3 and 4 , the inflatable portions ofcontainer 10, as well as the collapsed reinforcingretainer 64 are securely nested incavity 78. The upper andlower frames lid 44 secured in a closed position via corresponding upper andlower latch elements 58, thus provide a rigid, yet relatively small storage package for the deflated containers. Latches 80 (FIGS. 3 and 4 ) releasably clampupper frame 32 tolower frame 50 to form the rigid transport and storage enclosure.Handles 56 may be used to manually transport the rigid enclosure. - The foregoing description of an illustrated embodiment of the invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or to limit the invention to the precise form disclosed. The description was selected to best explain the principles of the invention and practical application of these principals to enable others skilled in the art to best utilize the invention in various embodiments and various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention not be limited by the specification, but be defined by the claims set forth below.
