<p>Collapsible container has a base and sides moulded from a synthetic plastics material and includes, at least partially encapsulated during moulding, elongate metal reinforcing elements. The reinforcing elements of the sides engage with those of the base to provide integral hinges. Interlock means at the hinges are arranged such that when, after initial moulding of the container base and sides in a flat condition, the sides are folded-up, the interlock means prevent return of the sides to the flat condition so that the container may thereafter be collapsed only by folding the sides inwardly over the base.</p> |
