Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a folding box according to the first embodiment of the present invention, in which a body 1 and a lid 2 are separated, as viewed from below. The body 1 is provided with a wing piece 3 having a lower part slightly outwardly protruding on an outer side surface of two opposing side walls thereof, and a lid 2.
Is provided with a step portion 4 for locking the wing piece 3 on the inner side surface of the two side walls corresponding to the wing piece 3, and the wing piece 3 and the step portion 4 constitute locking means. The locations where the wing pieces 3 and the step portions 4 are formed are not limited to the two side walls as shown in FIG.
Alternatively, four side walls or one side wall may be used. The lid 2 further includes a punching lid 5 that can be punched from the outside.

The body 1 has a pattern 10 as shown in FIG.
And assemble it. The pattern 10 includes a bottom surface 11, a pair of long side rising walls 12, a folded wall 13 extending outside each long side rising wall 12, a pair of short side rising walls 14,
And, it has a folded wall 15 extending outside each short side rising wall 14 (when the bottom surface 11 is a square, the concept of the long side and the short side disappears). Each folded wall 13,
15 is the same height as the long side rising wall 12 and the short side rising wall 14, respectively.

Each of the folded walls 13 and 15 is slightly extended outwardly, and comes into contact with the bottom surface 11 at the time of assembling.
7 is formed. A projection 18 is formed on one of the engagement pieces (an engagement piece 17 in the figure) as an engagement means and enters under the other engagement piece during assembly. 19 is a long side rising wall 1
It is a bent connecting piece for connecting the second side and the short side rising wall 14.

In each short side rising wall 14, a notch 20 with an upper side left uncut is made, so that the lower portion protrudes outward at the time of assembling and the step portion 4 formed on the inner surface of the lid 2.
One or a plurality of wing pieces 3 (1 in the figure) are formed. In order to make the wing piece 3 easily fall out of the notch 20 and to easily protrude outward, it is preferable that the notch 20 be slightly wide.

To assemble the pattern 10, for example, the long side rising wall 12 is raised vertically with the folded wall 13 folded on the long side rising wall 12, and then the bent connecting piece 19 is moved inward. After raising the short side side rising wall 14 vertically while bending, the folded wall 15 is bent so as to sandwich the bent connecting piece 19. Thus, body 1 is formed,
At this time, the wing piece 3 connected only to the upper side comes out of the cut 20 and the lower part slightly projects outward (see FIG. 6A).

The cover 2 is provided with a paper pattern 10 as shown in FIG.
Bend a and assemble. This pattern 10a is the top surface 2
1, a pair of long side rising walls 22, each long side rising wall 22
Has a folded wall 23, a pair of short side rising walls 24, and a folded wall 25 extending outside each short side rising wall 24 (when the top surface 21 is square, Does not have the concept of the long side and the short side.) Each of the folded walls 23 and 25 has the same height as the long side rising wall 22 and the short side rising wall 24, respectively.

Further, the long-side folded wall 23 is slightly extended outward to form an engaging piece 26 which comes into contact with the top surface 21 at the time of assembly to perform a shape-retaining action. And the short side folded wall 25
Is also slightly extended outward to form an inner folding piece 27. 29 is a long side rising wall 22 and a short side rising wall 24.
And a bent connecting piece for connecting the two.

A recessed wall 34 is formed in each of the short-side folded walls 25 by making cuts 30 on both sides and making one bent curve 31-33 on the upper side and two cut curves 31-33 on the lower side. An opening window 35 is formed at the center of the recessed wall 34, in other words, at the portion corresponding to the punch-out lid 5 when the short-side folded wall 25 is folded on the short-side rising wall 24. The folding curve 31 is slightly shifted outward from the folding curve 36 between the short-side folded wall 25 and the inner folding piece 27. The shift interval corresponds to the interval between the bent curves 32 and 33.

An example of an assembling method of the pattern 10a is as follows.
First, the inner folding piece 27 is folded on the short-side folded wall 25 and usually adhered (arrow a in FIG. 4). At this time, the fold curve 36 slightly deviates from the fold curve 31 of the concave wall 34, and the lower curve 32 has two fold curves 32 and 33 on the lower side. Becomes a mountain fold, so that the fold curve 31 can be bent. As a result, a recessed wall 34 whose lower portion is slightly inclined from the short-side folded wall 25 is formed, and the step portion 4 is formed (see FIG. 5).

Next, the short side folded wall 25 is folded inward, and the short side rising wall 24 is raised in a state where the short side folded wall 25 is overlapped with the short side rising wall 24. Then, the bent connecting piece 29 is folded inward while the long folded side connecting piece 29 is folded inward. The side-side rising wall 22 is raised, and finally the bent connecting piece 29
The long-side folded wall 23 is folded back so as to wrap around, and the shape is retained using the engaging pieces 26.

The lid 2 manufactured in this manner is put on the body 1 containing the goods as appropriate, and the step 4 is positioned below the lower end of the wing 3 on the outer surface of the body 1. To reach
The wing piece 3 whose lower part projects outwardly escapes into the space created on the step portion 4 (FIG. 6A). Even if the user tries to remove the lid 2 in such a state, the lid 2 cannot be removed because the wing 3 hits the step portion 4. That is, the sealed state of the product is maintained.

In order to remove the lid 2 from such a state, the lid 2
What is necessary is just to push inwardly the push-out lid 5 which exists in the outer surface of this with a finger | toe. By this punching operation, the punching lid 5 pushes the wing piece 3 inward through the opening window 35, and as a result, the wing piece 3
Is disengaged from the step portion 4 so that the locking action is released, and the lid 2 can be removed (FIG. 6B).

It should be noted that even if the push-out lid 5 is once pushed out, when the pressing force against the push-out lid is released, the push-back lid 5 immediately returns to its original state and has no action on the wing piece 3, so that the lid 2 can be removed. Often disappears. for that reason,
When removing the lid 2, the push-out lid 5 is lifted while being pressed with a finger.

The above-mentioned patterns 10 and 10a are merely examples, and a body 1 having a wing piece 3 whose lower part is slightly outwardly formed on the outer side surface of two opposing side walls, and this wing piece. If the lid 2 is formed on the inner side surfaces of the two side walls corresponding to the step 3, the stepped portion 4 for locking the wing piece 3 and the punching lid 5 capable of being pushed out from the outside can be formed. Needless to say, a pattern may be used.

In the second embodiment, the wings 41, 42 are provided on both the outer wall of the body 1 and the inner wall of the lid 2, and the wings 41 of the body 1 are provided.
The lower part projects outward, and the wing piece 42 of the lid 2 projects the upper part outward (FIG. 7). The wing piece 41 may be formed in the same manner as the wing piece 3.
Usually, the lower end of the lid 2 is formed by bending inward.

Also in this case, when the lid 1 is put on the body 1 and pushed down, the upper end of the wing piece 42 passes the lower end of the wing piece 41, and at the same time, the upper part of the wing piece 42 and the lower part of the wing piece 41 move outward. Tilt,
The two wings 41 and 42 are locked and locked.
The lid 2 cannot be removed as it is (FIG. 8).

In order to release the locked state, a method in which the pushing cover 5 is provided may be used. However, from the viewpoint of avoiding re-locking, it is preferable to cut or break the wing piece 42. . For that purpose, for example, a perforation 43 is formed in a portion corresponding to the wing piece 42 on the outer surface of the lid 2, and a portion including the wing piece 42 on the outer surface can be cut off by pressing the perforation 43 (FIG. 9). As a result, once the wing piece 42 is cut off to release the lock, and after the lid 2 is opened, the lock is not applied even if the lid is closed again.

The third embodiment uses an adhesive means as the lock means. To this end, for example, an appropriate amount of an adhesive 45 is applied to the outer surface of the body 1 and / or the inner surface of the lid 2, and a release paper 46 is fixed thereon (FIG. 1).
0). A perforation 47 for excision is provided at least around the adhesive 45 application portion on the side of the lid 2.

In this case, when the cover 2 is covered, each release paper 4
6 and cover the lid 2 at a stretch, and adhere the portions to which the adhesive 45 is applied. Then, when releasing the locked state and opening the lid 2, the adhesive portion is removed from the perforation 47. Note that a perforation 47 may also be provided on the side of the body 1 to remove the adhesive portions of both the body 1 and the lid 2 at the same time.
