Abstract
A container has a wall member; a front panel; and a rear panel generally parallel to and spaced apart from the front panel. The front and rear panels are connected about their peripheries to the wall member which extends between the front and rear panels to define a volume. The rear panel, the front panel and the wall member is a unitary, blow molded member including a generally rigid shell, and a plurality of flexible membranes each of which has a periphery and a surface. The periphery of the flexible membranes is bonded to the generally rigid shell. The surfaces of the flexible membranes are separated from the generally rigid shell to form a plurality of unbonded areas between the surfaces of the flexible membranes and the generally rigid shell. Air is contained within the unbonded areas, thereby forming a plurality of air pockets between the flexible membranes and the generally rigid shell.
