ABSTRACT:
A tidy box made entirely of polypropylene consists only of two parts fitted together after moulding. One part, the lower part, forms the base of the box together with a lid provided on one side with a catch or fastening lug and on the other side with a pull handle. The lid is made integral with the base by a polypropylene hinge so that the whole forms a single piece. The other part, the upper part, forms side parts, a top, back and front, the latter forming a fixed frame for the lid without any bottom cross-member, and the top has a notch and retaining edge for co-operating with the lid catch or fastening lug, the whole again forming only a single piece.
