According to the present invention, in order to achieve the above object, the invention according to claim 1 is characterized in that, in a rectangular parallelepiped assembly box, when unfolded, the right and left end plates and the upper and lower plates are arranged with respect to the side plate. Of the left and right wife plates, one wedge plate is provided with a hook-shaped slit from substantially the center of the upper end toward the center of the wedge plate, and the other wife plate is provided with a hook-shaped slit from substantially the lower end toward the center of the wedge plate. For the sheet member, the hook-shaped slits of the left and right endplates are formed by combining the sheet members provided in opposite positions so that the hook-shaped slits of the left and right endplates respectively mesh up and down. It was a box composed of two sheet members. As described above, since the hook-shaped slits are engaged vertically, the two sheet members act so as to be locked and fixed in the vertical and horizontal directions. Also, the left and right end plates are formed double, and the open end of the end plate is engaged with the inside of the bent corner of the other sheet member.

[0005] The invention according to claim 2 relates to a sheet member used for the assembly box according to the invention according to claim 1, comprising left and right end plates and upper and lower plates with respect to the side plate when unfolded. A sheet member for an assembling box, in which a hook-shaped slit is provided on one of the end plates from substantially the center of the upper end toward the center of the end plate, and the other end plate is provided with a hook-shaped slit from the lower end substantially from the center toward the center of the end plate. did.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows an unfolded state of the sheet member 10 for an assembly box according to the present invention, and a portion shown by a dotted line shows a bending position. On the left side of the side plate 11, the wife plate 12,
A wife plate 13 is provided on the right side, an upper plate (cover plate) 14 is provided above the side plate, and a lower plate (bottom plate) 15 is provided below the side plate. A hook-shaped slit 12a is provided on the left end plate 12 from substantially the center of the lower end toward the center of the end plate, and an inner upper plate (inner lid) 14a is provided on the upper portion. Here, the slit is formed from the substantially central portion of the lower end. In order for the two end plates to overlap when the hook is engaged, it is necessary to adjust the vertical slit position according to the horizontal width of the hook. Because there is. A hook-like slit 13a is provided on the right end plate 13 from substantially the center of the upper end toward the center of the end plate, and an inner lower plate (inner bottom plate) 15a is provided at a lower portion. When such a sheet member is actually cut, the hook-shaped slit and the cutout 14b of the upper plate and the cutout 15b of the lower plate are performed simultaneously with the outer shape. The material of the sheet member is not limited to corrugated paper, cardboard, or a thin resin sheet.

Next, a method of combining two sheet members into a box will be described. As shown in FIG. 2, the sheet member 10 and the sheet member 20 cut into the same shape are opposed to each other, the hook-shaped slits 13a and 22a provided on the end plate are engaged, and the hook-shaped slits 12a and 23a are also engaged. Let it. At this time, as shown in FIG. 3, the open end 12b of the end plate 12 and the open end 23b of the end plate 23 are engaged so as to be located inside the box. Although not shown, the opposite end plate is also engaged so that the open ends 13b and 22b are located inside the box. When engaged in this manner, the end plate of the box is formed double, and the open ends of the end plate are fixed inside the bent corners of the corresponding sheet members, thereby preventing the boxes from being deformed to each other. Further, when engaging the hook-shaped slit portion, the assembling work is facilitated by bending one of the end plates slightly left and right at the fulcrum by bending the slit portion. 2 and 3 show a hook shape cut in a straight line, but as shown in FIG. 4, if the slit located at the center of the end plate is formed into an arc-shaped slit 16, a sheet member When combined, the overlapping part of the wife plate becomes S-shaped and the center is easy to determine. Further, when the sheet member is cut into a shape, as shown in FIG. 4, if the outer shape is corrugated 17, troubles such as fingertips being cut off by the edge of the sheet member when handling the sheet member or box can be prevented. In addition, since a small step portion is formed in the engaging portion of the hook-shaped portion, when the fingertip is hooked on this portion, the handling of the box is easy.

[0008]

According to the present invention, hook-shaped slits are provided on the right and left end plates of the two sheet members in the upside-down direction.
Since the box is assembled by engaging the hook-shaped slits, parts and members different from sheet members such as metal fittings and adhesives are not required, and excellent collection and recyclability is achieved. Since the upper and lower displacements are locked, the shape retention as a box is also good.

Since the end plate is formed in a double structure and the open end is held inside the bent corner of the other sheet member, the open end does not open outward, and the strength as a box is excellent. Stacking is also possible, the sheet thickness per sheet member can be made smaller than before, and the weight can be reduced as a whole.
