Abstract
An inflatable insulated barrel cooler comprising a cylindrical, open topped, closed bottom, container constructed of sheet plastic or vinyl reinforced fabric. The cooler is somewhat rigid when inflated and in use yet is easily stored when collapsed. Insulation is provided by the trapped air of inflation. The cooler accommodates both 1/2 and 1/4 barrel sizes by incorporating a sleeve insert.
Claims11
An inflatable barrel container comprising:
- (a) a generally cylindrical container having an open top, a flexible, inflatable, closed bottom and a generally cylindrical, flexible, inflatable side wall(s), said container sized to approximately retain a barrel in spaced-apart registration with said wall(s), said side wall(s) including a plurality of interconnected, inflatable sections, said sections being generally tubular and attached to each other and interconnected to said bottom;
- and,
- (b) a valve in one of said inflatable sections to permit inflation,
- whereby when said collapsed container is inflated with air or the like gas through said valve, a semi-rigid container results which is self supporting, and a barrel may be easily placed inside said container with coolant placed in said space between said barrel and said wall(s), the barrel contents will thereby be kept at a constant temperature by the insulating value of said air-filled sections.

An inflatable barrel container comprising:
- (a) a generally cylindrical container having an open top, a flexible inflatable closed bottom and generally cylindrical, flexible and inflatable side wall(s), said container sized to retain a barrel in spaced-apart registration with said wall(s), said side wall(s) including a plurality of interconnected sealed inflatable sections, said sections being generally tubular and annular and circular in cross section, said sections attached to each other by their outer surfaces in stacked registration and interconnected and attached to said bottom;
- (b) a valve in one of said inflatable sections to permit inflation;
- (c) a drain proximate said container's bottom;
- and,
- (d) a generally parallelpipedal inflatable sleeve insert having an open top and bottom, and a continuous, double-sided, hollow wall, said wall including interiorly spaced-apart, Z-shaped brackets, said bracket's top and bottom bars defining the interior width of said wall, said insert sized so that when said container and said sleeve are inflated, said sleeve is retained in close registration within said container's wall(s).

An inflatable barrel container comprising:
- (a) a generally open parallelpipedal container having an open top, an inflatable bottom and inflatable side walls, said bottom being a hollow, sealed, parallelpiped interconnected to said side walls, said side walls each being a hollow parallelpiped and interconnected to each adjoining side wall;
- (b) a plurality of Z-shaped reinforcement brackets intermittently located inside said bottom and said side walls to provide dimensional control and to determine the interior dimension of said bottom and side walls;
- (c) a valve on one of said inflatable sections to permit inflation;
- (d) a drain extending from said container's interior proximate said container's bottom to the exterior of said container;
- and,
- (e) a generally parallelpipedal inflatable sleeve insert having an open top and bottom, and inflatable side wall(s), said walls being generally continuous and double-walled, hollow panels, said wall(s) including interiorly spaced-apart Z-shaped brackets, said brackets top and bottom bars defining the interior width of said wall(s), said insert sized so that when said container and said sleeve are inflated, said sleeve is retained in close registration with said container's wall(s).
