An erectable and collapsible container including a plurality of side walls joined along a plurality of wall hinges providing articulation between the side walls. A bottom wall is attached to the side walls at edge hinges providing articulation between the side walls and the bottom wall. At least one flexible gusset portion is provided extending between one or more of the side walls and the bottom wall, and the gusset portion is movable with the bottom wall in response to movement of the side walls and the bottom wall between collapsed and erected configurations. Structure is provided for maintaining the side walls in the erected configuration such that the side walls define a generally rigid or semi-rigid structure. A pair of opposed flexible panels extend from the side walls and define a bag-like upper portion extending from the support structure and forming a sealable opening for the container.
