ABSTRACT:
A bowl shaped container having a polygonal shaped bottom section; rectangular, square, or trapizoidal side sections; and top closure material which folds down in a spirling fashion, which may or may not lock, included in the design. The container will be preferably formed from a single sheet of foldable material, which, through a unique folding process, creates the bottom, side panels and top closure. The description defines an open bowl shaped polygonal container with top covering material which folds down toward the center of the top of the container in a generally spiral fashion. The container provides a receptacle which can be closed through a folding action, and can be reopened to the near flat state again without great effort.
