Title: Collapsible container

Abstract: A collapsible container with or without a lid for carrying and storing articles comprising at least one side plate formed in its inner surface with recessed portions aligned along one end thereof and each having a vertical pin supported by opposed walls defining the recessed portion, and another adjacent side plate having hinge projections provided on one of its opposite ends adjacent to the first-mentioned side plate. The hinge projections rotatably retain the vertical pins in engagement therewith to render the container completely collapsible. Each of the hinge projections disengageably abuts against an outer wall defining each of the recessed portions to impart increased buckling strength to the container.
