IMPROVEMENTS IN OR RELATING TO BOXES OR PACKS FOR PACKAGING EGGS, FRUIT OR OTHER ARTICLES

摘要

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.
