Abstract: An eggbox, which is a one-piece moulding of plastics sheet material, comprises a base part having egg-receiving pockets and a cover part having corresponding pockets hinged together along mutually adjacent rims so that the cover part can be folded over the base part to close the latter. In the closed position, the parts are fastened together at their rims opposite the hinge by cooperating studs and slots formed respectively on the two parts. The slots are of key-hole shape and, when the cover part is closed, the studs initially engage in the wider portions of the slots and are urged into engagement with the narrower portions by the inherent resiliency of the parts in order to fasten the parts together. A second set of cooperating studs and slots, which interengage in the manner of press-stud fasteners, are formed centrally of the base and cover parts in order to assist in fastening the parts together.

Abstract: A pour spout for a carton is formed from the carton material in two superimposed panels. The outermost panel has an opening and a tab member, the first end of which is connected to the remainder of the panel at a fold line. The second or opposite end of the tab member is part of the perimeter of the opening. The first and second ends of the tab member are defined by parallel rows of perforations. The inner panel includes a tab member which is aligned with the first tab member. A pair of wing members extend from fold lines at opposite side edges of the inner tab member. The wing members may have an arcuate edge and may include a projection which will limit pivotal movement of the spout formed by the tab members and wing members. The superimposed panels may be overlapping side panels, overlapping top panels, or a combination of side panels and top panels having extensions which overlap the side panels. In one embodiment, a separate insert serves as the innermost panel.

Abstract: Interlocked partition strips are shown and described wherein each strip has a number of spaced parallel slots which divide the strip into segments or sections. All but one end segment have lock tab projections near one edge extending into the slots in one direction. Also, the one end segment and all other segments but the remaining end segment have lock tab projections spaced inwardly from such one edge, the latter projections extending through the slots in the same direction, but opposite to the direction in which the projections adjacent the edge extend. Thus, each slot has two spaced, oppositely directed lock tabs extending through it. At the opposite edge of each strip are spaced tab receiving openings to be interfitted with lock tab projections of a transverse strip.
