Claim:
A storage/transport container comprising: a plurality of walls defining an upwardly open vessel having an upper rim; a generally flat cover panel hinged on one of the walls and having an inner edge, the rim having opposite to the one of the walls another inner edge, the cover panel being pivotal into a closed position with the inner edges juxtaposed; retaining formations projecting generally perpendicularly from the inner edge of the cover panel and oppositely from the other inner edge that fit together in the closed position; and hooks formed on the edges, positioned so as to be opened directly away from each other in the closed position, and each having a hook part spaced from the respective inner edge, the hooks normally being spaced apart but, on deformation of the cover panel, hooking together with each hook part engaging between the other hook part and the inner edge of the other hook part and preventing separation of the edges.
