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.

A box or pack for packaging eggs, fruit or other articles, in which a base part having mutually parallel rows of article-receiving pockets is formed in one piece with a hollow cover part, the parts being hinged together along mutually adjacent rims substantially parallel to the rows of article-receiving pockets so that the cover part can be folded about the hinge from an open position to a closed position in which it is inverted over the base part and closes the open, upper ends of the pockets therein, characterised in that the cover part is fastened in its closed position by one or more cooperating studs and slots formed respectively on the two parts adjacent their rims opposite the hinge, the or each slot extending transversely to the axis of the hinge and being wider at or adjacent one end, whereby when the cover part is closed, the cooperating stud is initially engageable with the wider portion of the slot and is urged into engagement with the narrower portion by the inherent resiliency of the base and cover parts in order to fasten the two parts in the closed position.
