ABSTRACT:
A collapsible container in the form of a thin sheet material body which is capable of being collapsed by being folded upon itself. When unfolded the body assumes a cone shaped or pyramid shaped chamber. Incorporated within the body is a center section which can be deflected into a cone shape or pyramid shape which is oppositely oriented to the cone shape or pyramid shape of the chamber. The deflected center section will function to retain the container in its expanded position thereby permitting the chamber to be used for small foodstuff particles such as pretzels, potato chips, popcorn and the like. There is a further embodiment which does not require deflection but is constructed of multiple parts that are assembled in a similar cone shape or pyramid shape configuration to form two separate chambers.
