    Abstract: A case for packing small objects such as writing utensils, watches, lighters and the like. A lower part made from a deep-drawn foil material has vertical side walls and a centrally arranged trough-shaped depression and constitutes at least a partial structural support for the casing. Further support is provided by a relatively stiff bottom part. The lower part has a step shoulder along at least one edge and hinge recesses in the two side walls adjoining that edge and aligned with the step shoulder. A lid, preferably of a stiffer material, has a pair of opposed hinge pins along one edge, which hinge pins are received in the recesses as the said edge of the lid is supported at least in part on the step shoulder. The lower part may have additional step shoulders along other side walls to support the lid in the closed position thereof.
