ABSTRACT:
A container for food articles including a tray upon which the articles can be stacked, and opposed side members hingedly secured to the tray to retain the articles in the stacked disposition. The side members are moveable between an open position where the articles can readily be stacked or removed from the tray, and a closed or raised position where the sides are secured in place and the articles are restrained from lateral movement relative to the tray due to the inward shape of the side members. Cooperating means are provided in the lower portion of the inward portion of the side members and in the tray to hold the side members in the raised position. The side members can be formed such that in the closed position they are substantially open along the top to expose the top of the stacked articles, and along the ends or sides a small portion of the articles can be exposed to enable access for insertion of the articles into the container or facilitate their removal. The container can be vacuum molded and can be attached along common edges of the side members of adjacent containers to form a multiplicity of containers in a single molding operation.
