The present invention relates to an improved collapsible square case having a square open top and being particularly adapted for holding a plurality of items. The case includes a pair of opposed corner panels. Each of the corner panels has a flat side and a corner wall formed integral with one edge of the respective flat side being substantially perpendicular to the flat side. Each of said corner panels being an integral molded plastic panel. Said flat sides are parallel to each other. Said corner walls are parallel to each other. A pair of flat panels, each having one edge hingedly connected to a corner wall and the opposite edge connected to the edge of the flat side of the other corner panel. Each of the flat panels being an integral molded plastic part. A floor panel being an integral molded plastic part. Said floor panel being hingedly connected to the lower edge of a flat side of one of the corner panels. All of the panels being adapted to be subjected to high temperature and moisture to clean the panels. Raising of the floor panel adjacent to its respective flat side allows the case to collapse and placing hingedly connected flat panels in an attitude whereby each flat panel is in substantially the same plane as the respective flat side. A collapsed case may be stacked on top of another like collapsed case.

A collapsible square case having a square open top particularly adapted for holding a plurality of items comprising, in combination, a pair of opposed corner panels, each of said corner panels having a flat side and a corner wall formed integral with one edge of the respective flat side and extending substantially perpendicular to the respective flat side, each of said corner panels being an integral molded plastic part, said flat sides being parallel to each other, said corner walls being parallel to each other, a pair of flat panels, each of said flat panels having one edge hingedly connected to a corner wall and the opposite edge of the flat panel connected to the flat side of the other corner panel, each of the flat panels being an integral molded plastic part, and a floor panel being an integral molded plastic part, said floor panel being hingedly connected to a lower edge of flat side of one of the corner panels, whereby the panels may be subjected to high temperature heat and moisture for cleaning the panels, and raising of the floor panel allows the case to collapse with the floor panel adjacent to its respective flat side and the hingedly connected flat panels placed in an attitude whereby each flat panel is in substantially the same plane as the respective flat side, a collapsed case may be stacked on top of another collapsed like case, a pair of posts formed integral with a flat side of one of the corner side panels, each of said posts being substantially perpendicular to the flat side, the flat side of the other corner side panel having a plurality of receptacles for receiving the posts, each of the flat panels having a receptacle for receiving a post, whereby a pair of like cases being opened and placed adjacent to each other allow the posts of one case to fit into the receptacles of the other case for stabilizing the positioning of the cases, and when the cases are collapsed and the cases are stacked in a collapsed attitude, the posts mate with the receptacles to stabilize the stack.
