[Detailed description of the invention] The present invention relates to a case mainly used for writing pens, etc., in which two-tiered cases are interconnected and a lid is attached to the case.The illustrated embodiment is a square plate. A pair of upper and lower writing case bodies 1, 1' made of hard synthetic resin having a shape are provided with sleeves 1-2, 2' penetrating vertically over the entire back wall. An engaging protrusion 6... is provided on the side wall surface, and an engaging protrusion 14..., 14'... is provided on both the inner and outer wall surfaces, and two separate engagement protrusions are provided. Both sides plates 4, 4' are arranged in a bendable manner on both sides of the foldable bottom part 4'', and the above-mentioned engaging protrusions 6 are fitted onto the outer surfaces of these side plates 4, 4'. Engagement recess 5... and hook-shaped projections 15 that engage with the above-mentioned hook-shaped projections 14..., 14'... on the inner and outer surfaces thereof. ..., 15'...
A synthetic resin hinge member 3 is constructed, and a thermoplastic synthetic resin sheet 8 is wrapped around a core material 7 made by polymerizing sponge on the top surface of cardboard, and a coreless continuous portion 9 is constructed. Exterior plate 1 with both upper and lower plates 10 and 11 integrally arranged on both sides

2. Insert the side plates 4, 4' of the hinge member 3 between the inner wall surface of 2' and the coreless continuous portion 9 of the exterior plate 12, and the engagement provided on the side plates 4, 4'. Recessed portion 5 (slip) 2. Engagement protrusion 6 provided on the inner side surface of 2'

4..., 14'...... to make it impossible to remove the side plates 4.4' from the sleeves)-2, 2', and furthermore, the outer plate 12 is continuous without a core. A hook-shaped projection 1 provided on the inner surface of both side plates 4, 4' of the hinge section 3 is inserted into the engagement hole 13 provided in the section 9.
5 and the rib) 2 and 2' outer wall surfaces with hook-shaped protrusions 1
By fitting the retaining part 4', the exterior plate 12 cannot be distally disposed, and both the upper and lower printing plates 10, 11 are attached to the upper and lower parts of the upper and lower pencil case bodies 1, 1'. It is installed so that both openings can be opened and closed.

As described above, the present invention provides slits penetrating vertically in the backs of a pair of upper and lower case bodies, inserts both sides of the hinge member that can be folded into two into the slits of each case body, and inserts the two side plates of the hinge member into the slits of each case body. By fitting and engaging the retaining protrusions and hook-shaped protrusions provided on the sides of the slit with the engagement recesses and hook-shaped protrusions provided on the slit, both sides of the case body cannot be removed from the snot. Since they are arranged side by side and opened and closed in a two-tiered state, it is extremely easy to connect the pair of case bodies so that they can vibrate freely.In addition, both the upper and lower heat plates are integrated on both sides of the continuous coreless part. The coreless continuous part of this exterior plate is inserted into the slits of both the upper and lower case bodies, and the slit and the side plate are inserted into the retaining holes provided in the coreless continuous part. By fitting the engaging parts of each engaging protrusion, the exterior plate was attached to both the upper and lower case bodies in a state in which both the upper and lower lid plates opened and closed the upper and lower openings of both the upper and lower case bodies, so the above two-tiered case This also has the advantage of being extremely easy to attach the lid to.

Claims (1)

[Scope of utility model registration request] A slit is provided in the back of the pair of upper and lower case bodies that passes through the upper and lower sides, and both sides of the hinge member that can be folded in half are inserted into the slit of the case body, and the engaging recesses and hook-shaped protrusions provided on the side plates are inserted. By fitting and engaging the retaining protrusions and hook-shaped protrusions provided on the sides of the slit, and making it impossible to remove the two side plates from the slit, both the upper and lower case bodies can be opened side by side, creating a double-layered structure. In addition, an outer plate is formed in which both the upper and lower plates are integrally connected on both sides of the coreless continuous part, and the coreless continuous part of this outer plate is inserted into the slits of the upper and lower case bodies. In addition, by fitting the above-mentioned engaging portions of the slits and the retaining protrusions provided on the side plate into the retaining holes provided in the coreless continuous portion, both the upper and lower plates can be attached to the upper and lower case bodies. A case that is attached to open and close the upper and lower openings of both case bodies.
