PROBLEM TO BE SOLVED: To costlessly produce a case for refreshing granular materials which can be conveniently carried and appropriately used by every small quantity and which is excellent in the pressure resistance during use, by use of the minimum number of parts in a stable assemblying process. SOLUTION: This card-shaped case is assembled with a rectangular tray- shaped bottom member 20 and a rectangular cover member 10 by fitting a plurality of sets of protrusion and recession bosses projected on the inside face of the bottom member 20 and the cover member 10. A part of the side wall of the bottom member 20 is formed to integrally shape a hinge cap 50 with the bottom member 20. Projections 52a, 52b formed on both side faces of the hinge cap 50 are fixed to the protrusion formed on the outside face of an outlet partition wall formed on the bottom member 20, so as to freely open or close it, and a fitting stopper is formed to contact the top of the recessed boss when the protrusion and recession bosses are fitted, at the outer periphery of the protrusion boss. The outside face of the hinge cap 50 is provided with protrusions and recesses. |
