ABSTRACT:
A self-erecting container which is collapsible into a flat storage position. The container includes a top member with an opening into the container, a bottom member and a plurality of walls extending between the top member and bottom member. The walls pivot with respect to the top member and the bottom member. Further, each wall has upper and lower wall sections which pivot with respect to each other. A bracket is suspended within the container by a plurality of elastic members. Each elastic member extends between the inner surface of one of the walls and the bracket. The elastic members bias the container into an erected position. When an external influence overcomes the bias, the walls collapse such that the container assumes a flat position. Alternatively, the container may be biased by an elastic band connected to the inner or outer surfaces of the walls of the container.
