Abstract
Abstract An inflatable box of resilient sheet material such as rubber or vinyl, comprising a plurality of inflatable panels integrally joined along fold lines to provide a bottom wall, side walls and a top wall which may also function as an openable cover. The box may be made water-tight by providing non-inflatable folds or webs of waterproof material integrally joining each side panel to the side panels adjacent thereto along their respective adjoining edges. An air valve is provided in one of the inflatable panels to introduce air under pressure in that panel, and into the other inflatable panels through connecting passageways. The panels are inflated when they are lying flat. They are then folded along fold lines to form the box, and the panels are held in such position by side wall fasteners. A fastener may also be provided on the top cover panel to hold it in closed position. The air filled inflatable panels provide good insulation against heat transfer, so the box is particularly useful as an ice chest and for storing or transporting items packed in ice. When not being used as a box or container, the panels may be deflated whereupon the box may be folded into a compact unit for storage.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
275 words
An inflatable container, comprising a plurality of waterproof inflatable panels, including a bottom inflatable panel, a first end inflatable panel adjacent one end of said bottom inflatable panel, a first side inflatable panel adjacent one side of said bottom inflatable panel, a second side inflatable panel adjacent the opposite side of said bottom inflatable panel, a plurality of waterproof non-inflatable panels of flexible sheet material each having four sides adjacent ones of which are substantially normal to each other and opposite ones of which are substantially parallel to each other, a first of said non-inflatable panels having a first side edge connected along a side of said first end inflatable panel and a second side edge connected along an adjacent side of said first side inflatable panel, a third side edge of said first non-inflatable panel including first fastener means thereon for cooperative fastening engagement with second fastener means, a second of said non-inflatable panels having a first side edge connected along an opposite side of said first end inflatable panel and a second side edge connected along an adjacent side of said second side inflatable panel, a third side edge of said second non-inflatable panel including said second fastener means thereon for cooperative fastening engagement with said first fastener means when said bottom, side and end inflatable panels are folded into a box configuration, said first non-inflatable panel is triangularly folded on itself and folded against said first end inflatable panel, said second non-inflatable panel is triangularly folded on itself and folded against said first non-inflatable panel whereupon said first and second fastener means come into registration with each other for fastening engagement together.
