Abstract
A container (10) with lower and upper parts of formed plastic sheeting, is constructed of two identical elements (12, 14) that can close and latch to each other to form a closed container by turning a second of the elements upside down to make it the upper element, and pressing it down against the lower first element. The lower element includes a base wall (20) which is the bottommost wall and which has a vertical axis (22), upstanding side walls (24), and a flange (30) extending radially away from the top of the side walls. Along a left half (34) of the lower element, the flange forms an upward projection(s) (42), and along the right half (36) of the lower element the flange forms an upwardly-opening groove (44). Each projection and groove extends in a zig-zag line along the flange.
