Description

[Detailed Description of the Invention] This invention relates to an assembly type box made from a thin plate material such as cardboard, and its purpose is to facilitate one-touch assembly.

This invention will be explained based on an illustrated example.
, 3.4 are walls forming each side of the peripheral wall of the box B whose front shape is square, and these wall portions 1.2, 3.4
constitute a rectangular peripheral wall plate 8 that continues sequentially in the same direction via the fold lines 5, 6, and 7.

Narrow folded parts 9 are formed on both sides of each wall part 1 to 4 (the upper and lower sides in FIG. By this box B
Plate pieces 10, 11゜1 constituting the front or back part of
2.13 is coupled.

The basic shape of the plate pieces 10 to 13 is a right-angled isosceles triangle with the sides of the walls 1 to 4 as hypotenuses, and an outer edge 10 to be described later.
a, 11 a, 12 a.

13a and insertion pieces 10b, 11b, 12b
, 13b are formed.

The outer edges 103 to 13a appear approximately diagonally on the surface of the front or back portion of the box B when the plate pieces 10 to 13 are interlocked with each other, and the peripheral wall plates 8
The same side of each plate piece 10 to 13 (
It is formed in a diagonally convex curve shape on the right side in Fig. 1.

In addition, the insertion pieces 10b to 13b are the outer edges 108 to 1 of the adjacent plate pieces 10 to 13 (plate piece 10 in the case of plate piece 13), respectively.
It is inserted into the back side of the plate 3a, and the endmost plate piece 10 is formed to be slightly larger than the other plate pieces.

However, the folded portions 9 on both sides of each wall portion 1 to 4...
With the plate pieces 10 to 13 folded inward, the plate pieces 10 to 13 are attached to each wall part 1 to
4, between the walls 1, 4 at the ends of the peripheral wall plate 8 and the adjacent walls 2, 3 (i.e.,
between the walls 1 and 2 and between the walls 3 and 4), the insertion pieces 11b and 13b of one of the plate pieces 11 and 13 are placed on the back side of the outer edges 10a and 12a of the other plate pieces 10 and 12. In the polymerized state, they are bonded together using a bonding means such as an adhesive or a paper staple.

And the plate pieces 10, 11, 12 joined together in this way
．． 13, the insertion side plate pieces 11 and 13 are bent along diagonal fold lines 14° and 15, respectively, and
The walls 1 and 4 at both ends are bent along fold lines 5 and 7 on the center side, thereby folding the entire both end portions toward the center.

16 is a protrusion for insertion. As mentioned above, before assembly, the box of this invention has both ends folded toward the center to form a flat shape, and when assembled, both ends are opened like double doors, as shown in Figure 2. The wall portions 14 at both ends are made to stand up against the wall portions 2 and 3 located in the middle.

Then, while bending the two right-angled parts along the center fold line 6, insert the insertion piece 10b of the plate piece 10 of one part (the left part in FIG. 2) into the plate piece 13 of the other part.
The insertion piece 12b of the plate piece 12 is inserted into the back side of the outer edge 11a of the adjacent plate piece 11.

By inserting in this manner, the plate pieces 10 to 13 are intertwined with each other at the central portions of the front and back sides, forming a box B whose six sides are covered.

On the front and back sides of this box B, the outer edges 10a to 13a of each of the plate pieces 10 to 13 are exposed, creating a square-shaped pattern.

Note that the outer edges of each of the plate pieces 10 to 13 may be formed into a convex curved shape or may be formed into a straight line.

The box of this invention has the structure described above, and is assembled by standing up the walls at both ends and bending the two left and right parts along the center fold line, which eliminates the troublesome work of fitting the pieces together. It is extremely easy to assemble with one touch.

In addition, since there are folded parts on both sides of each wall, the assembled box is strong and durable, and the board pieces interlock with each other without any play, which increases the strength from this point as well. do.

Claims (1)

[Scope of utility model registration request] The walls that form the peripheral wall of a box with a square front shape are successively continued in the same direction to form a rectangular peripheral wall plate, and the front side of the box is connected through narrow folded parts on both sides of each wall of this peripheral wall plate. The plate pieces constituting the front or back part of the box are interconnected, and each plate piece has an outer edge that appears approximately diagonally on the surface of the front or back part of the box. An insertion piece that is inserted into the back side of the outer edge of one plate is provided, and the insertion piece of one plate is inserted between the wall at the end of the peripheral wall plate and the adjacent wall. This is an assembly type box in which both end portions are folded toward the center by joining the plates in an overlapping state on the back side and bending the plate pieces on the insertion side along diagonal fold lines.
