<p>PURPOSE: To store a video film cassette having one size out of several kinds of sizes by minimum remodeling. CONSTITUTION: A upper section 1, a bottom 2 and a lid 3 are made of a somewhat hard plastic material and assembled to form a box container. The bottom 2 and the lid 3 are formed integrally, and the thickness along a line 4 is reduced to form a hinge. Two steps 23 and 24 of a side wall 22 have their corners between three side planes of two rectangles shown respectively by dashed lines 27 and 28. The remaining side plane of each rectangle extends into the lid 3, and each rectangle defines the outline of a video cassette. To store a smaller cassette, an insert shown by broken a line 29 is placed in a clearance 31 between side walls 17 and 22 before the cassette is inserted.</p> |
