Abstract
A trash container having a base and sides, at least a portion of the sides being formed of resilient horizontal pleated material throughout the circumference thereof, and a plunger fitting within the trash container and having a horizontal cross-section conforming to the internal horizontal cross-section of the trash container, the plunger including lips extending about the periphery thereof and shaped and dimensioned to fit over the upper edges of the sides. Alternatively, the top of the container may be used as a plunger. Pressure on the plunger will cause the sides to compress the pleated material, permitting the plunger to be pressed downwardly on the trash and compacting it. In a modification, the sides are rigid and the resilient pleated material is in the top of the container. The pleated or other resilient material has a memory and, so, will return to its original shape after pressure is removed.
