Abstract: A photographic print and storage unit includes a frame and a tray. A stack of photographs is held within the tray and against the frame by a set of stack lifting members activated when the frame and tray are closed. The stack lifting members include a cam plate that is compressed by the closing of the frame to lift a flexible finger against the bottom of the stack pressing the stack against the inner surface of the frame regardless of the number of pictures in the stack. An integral negative tray stores the negatives and a leg, detachably molded to the tray, may be used in conjunction with a series of mounting holes to provide support to the storage unit for tabletop display. The tray and frame are molded in one piece and attached by means of a living hinge of molded material.

Abstract: A toy packaging is disclosed, which comprises a generally cylindrical container having an open end that is closable by a cap, and, in combination with this container, the toy hat that is removably fixable onto the upper end of the container, the hat having a cut-shaped portion sized to fit onto a child's head. Advantaeously, the cup-shaped portion of the toy hat is of such a diameter as to snuggly fit onto the upper end of the container, and a full-sized picture of a child's face is provided onto the wall portion of this container adjacent the upper end thereof. Thereby, when the toy hat is press-fitted onto the container, it seems to be worn by the child whose face is on the picture. This toy packaging is particularly well designed for use to sell, store and put away toys construction blocks including coupling elements making them detachably stackable onto the other.

Abstract: A container is provided with an inner container body and an outer sleeve. The inner container body (which is preferably, but not necessarily, a one-piece structure) includes upper and lower essentially rigid portions and a flexible liner portion therebetween. In one embodiment, the sleeve is positioned between opposing annular upper and lower ledge surfaces defined by the upper and lower rigid portions, respectively, so as to positionally separate the same. Most preferably, the sleeve is sized so that its upper and lower edges are respectively seated against the upper and lower ledge surfaces so as to exert a tension force upon the flexible liner. This tension force, in turn, causes the upper and lower portions of the inner container body to be compressively coupled to upper and lower edges of the sleeve (e.g., by biasing the upper and lower ledge surfaces into seated contact with the sleeve's upper and lower edges, respectively).

Abstract: A food container comprises top and bottom members, with the bottom member including a lower base wall and an upwardly extending side wall. Spaced apart downwardly extending depressions are formed in the lower base wall, and each of these depressions has an inside wall surface spaced inwardly from the surrounding side wall. The inside wall surfaces of the depressions collectively define an outline, and the top member has a raised central portion the outline of which is substantially identical to but slightly smaller than the outline defined by the depressions. This relationship enables the raised central portion of the top lid member to interlockingly fit between the depressions when assembled food containers are stacked one above the other. The raised central portion of the top lid member has less height than the depressions which spaces the lower base wall from the raised central portion when assembled containers are stacked.

Abstract: A disk shipper is configured so as to allow the disk contents to be handled either by their internal diameter or by their external diameter. The bottom of the disk shipper is further configured so as to be compatible with certain existing disk carriers in transferring the disk contents to the particular disk carrier and vice versa. Since the particular disk carrier with which the bottom of the disk shipper is compatible prohibits external diameter handling, the novel disk shipper bottom facilitates transposing the disks into a configuration that permits both external and internal diameter handling. Supporting members inside the disk shipper maintain the disks in axial alignment preventing relative motion of the disks during handling.

Abstract: In a plastic molded tote box having one lid or opposed lids that will shingle with other lids in the open position when the box and like boxes are nested, the maximum horizontal dimension for the shingled lids, as measured outwardly from the adjacent box side wall (lid flare), is reduced by tapering the lid rib structure toward the hinge, and/or by tapering the outboard lid skirt toward the hinge, and/or by flaring one or more lid flanges, particularly the inboard flange. The latter two structural features permit increased nesting of the lid side skirts or channels, which in the closed position of the lid overlie the box side walls.
