Abstract
An improved container construction, particularly useful for arranging and securing a plurality of separable items therein. The unassembled container has a generally planar configuration and contains a bottom wall defining a floor upon which the items to be packaged are placed. The container includes side walls which are connected to adjacent floor edges by hinge lines. Shoulder members are formed on the floor and surfaces of the side walls adjacent each hinge line, and serve to define closure limits for the side walls when the container is assembled.
Claims9
A tray-like container formed of foamed polystyrene, which can be stacked with unassembled in a generally planar configuration prior to use, comprising:
- a bottom wall of generally planar configuration having a bottom surface and a floor surface upon which items to be packaged can be placed;
- a plurality of side walls surrounding said bottom wall each being formed so as to lie in a plane parallel to said floor surface when open, each of said side walls being contiguously connected to one edge of said floor surface of said bottom wall by hinge lines therebetween and having an upward extent substantially smaller then the smallest lateral extent of said bottom wall;
- abutment means formed on said container adjacent said hinge lines positioning said side walls over said bottom wall at a predetermined acute angle with respect to said floor surface and disposing free outer corner edges of said side walls in a single plane;
- and
- plastic film shrunk-fit across the top of said container enclosing articles therein and forming a planar sheet across said free outer corner edges of said side walls.
