ABSTRACT:
A collapsible container includes plural side walls joined so as to be movable between a generally flat condition, and an erected condition whereby an interior area of preselected cross-sectional geometry is defined. A bottom wall is removably coupled to a lower region of the side walls when in their erected condition. The bottom wall thus serves, at least in part, to assist in maintaining the side walls in their erected condition. A peripheral seal is provided with the bottom wall so that when it is coupled to the side walls, the bottom and side walls will be sealed to thereby minimize (if not eliminate) leakage therebetween. Preferably, the seal is flexible and is outwardly flared so that when the bottom wall is coupled to the side walls, the seal will engage the latter and be inwardly flexed against its tendency to flare outwardly. This inward flexion of the seal ensures that sealing contact is maintained between the seal and the side walls. The seal may also be provided by an annular bead formed on a peripheral edge of the bottom wall which seats with an annular concavity formed on the side walls and thus effectively seal the bottom and side walls thereat.
