Abstract: A plastic shoe box assembly includes a folding body made of a transparent and semi-transparent plastic material, side cover plates, an upper cover plate, and fastening lugs. The folding body is formed with shallow grooves such that the folding body is foldable along the shallow grooves into a U-shaped body, and has front and rear end portions provided with slide grooves. The side cover plates may be inserted into the slide grooves from an upper end of the U-shaped body, and has stop blocks and resilient retaining members engageable with stop grooves and retaining grooves for coupling purposes. The upper cover has front and rear ends connected to the fastening lugs, which has color or number indications. After assembly, projections at the inner edges of the fastening lugs can engage fastening holes in the side covert plates to position the upper cover plate. The shoe box assembly saves storage space prior to assembly, and can be quickly assembled when desired.

Abstract: A compact disc holder combination includes a flat carrier having a positioning through hole and a pair of clasp slots oppositely disposed therein at suitable positions, and a pair of clasp seats. At least one of the clasp seats having a pawl for holding a compact disc. Each clasp seat is provided with a plurality of posts and insert holes on a rear side thereof. The clasp seats are fitted onto opposite surfaces of the carrier at the positioning through hole in such a manner that the posts of one clasp seat fit into the insert holes of the other clasp seat while the insert holes of the one clasp seat receives the posts of the other clasp seat. Their connection may be reinforced by welding or using an adhesive agent. Both clasp seats may be provided with a pawl for keeping two compact discs on opposite surfaces of the carrier. The grip slots facilitate placement or removal of smaller size compact discs.

Abstract: A field glasses comprising a flat, rectangular bottom shell, a flat, rectangular cover shell, an object lens assembly pivoted to said bottom shell at one end and supported by a torsional spring into a vertical position, an eyepiece assembly pivoted to said bottom shell at an opposite end and supported by a torsional spring into a vertical position permitting the eyepieces thereof to be respectively in line with the object lenses on said object lens assembly, and two opposite folding side strips foldably connected between said bottom shell and said cover shell at two opposite sides. Pushing said object lens assembly and said eyepiece assembly inwards respectively causes the field glasses to be collapsed into a flat, pocket size structure for carrying in a pocket.

Abstract: A disk storage box comprised of two pivoted shells connected by two axle caps with a hollow shaft retained therebetween to hold a plurality of flat disk holders. Lifting one shell from the other causes said axle caps to rotate said hollow shaft, permitting said flat disk holders to be spread out like a fan for arranging laser disks or floppy disks conveniently. Stop strips are made in connecting rings on one shell to confine said axle caps to be rotated within a fixed angle.
