Therefore, if the insertion piece is inserted into the notch portion provided on the tongue piece, and the engaging portion provided on the insertion piece is engaged with the peripheral portion of the notch portion, the insertion piece is It will not be unnecessarily removed from the notch. That is, the lid wall is securely fixed to the peripheral wall of the box body.
On the other hand, if the user applies an external force to the packaging box to break the cut line, it is easy to remove the insert from the peripheral wall of the box body (cut it into thousands). If the insert piece is cut off from the peripheral wall of the box body, the fixing of the lid wall to the peripheral wall of the box body is released even if the engagement between the engaging portion and the peripheral edge of the cut-out portion is not released. And the lid wall opens easily.

  In the present invention, the insertion piece protrudes from the tip of the portion surrounded by the cut line (hereinafter referred to as the surrounding portion) on the peripheral wall of the box body. When the lid wall is closed, for example, if an external force is applied to the surrounding portion from the outside of the packaging box, the cut line is easily broken. The user cuts out the insert piece from the peripheral wall of the box body together with the surrounding portion.

  In the present invention, the cut line is partially broken, so that it is easy to break.

In the present invention, a crease is provided at a boundary portion between the insertion piece and the peripheral wall of the box body. Part of the cut line (both ends of the line) is disposed at both ends in the length direction of the fold.
When the lid wall is closed, if an external force is applied from the outside of the packaging box to the part surrounded by the line center part of the cut line and the crease (hereinafter referred to as the line surrounding part), the line center part of the cut line is Easily breaks. At this time, if the fold is fold-folded when viewed from the outside and the line surrounding portion is pushed into the inside of the packaging box, a new opening is formed in the box body. If a finger is inserted into the inside of the packaging box from this opening and an external force is applied from the inside of the packaging box, both ends of the cut line are easily broken. The user cuts out the insertion piece from the peripheral wall of the box body together with the line surrounding portion.

  In the present invention, the insertion piece is supported between the two cuts in the peripheral wall of the box body.

  In the case of the packaging box of the present invention, the lid wall is useless by inserting the insertion piece into the notch and engaging the engaging portion provided on the insertion piece with the peripheral edge of the notch. Opening can be suppressed. On the other hand, when the user breaks the cut line, the fixing of the lid wall to the peripheral wall of the box body is released, so that the lid wall can be easily opened.

Therefore, it is suppressed that the cover wall 3 of the packing box 1 packing the articles is unnecessarily opened.

When opening the packaging box 1, the user applies an external force to the packaging box 1 to break the cut line 5. More specifically, first, the user applies an external force to the portion surrounded by the line center portion 52 and the crease 61 (hereinafter referred to as the line surrounding portion 22a) from the outside of the packaging box 1 to the rear. Then, the line center part 52 breaks easily. Next, the user pushes the wire surrounding portion 22 a into the inside of the packaging box 1. At this time, the line surrounding portion 22a swings backward about the crease 61, and the tongue piece 32 swings backward, so that an opening is formed in the front wall 22. Next, the user inserts a finger into the inside of the packaging box 1 through the opening formed in the front wall 22 and applies an external force to the packaging box 1 from the inside to the top of the packaging box 1. Then, both ends 51 and 51 of a line break easily.
In this way, the user cuts out the insertion piece 4 from the front wall 22 together with the line surrounding portion 22a. As a result, the fixing of the lid wall 3 to the front wall 22 is released. Therefore, the lid wall 3 is easily opened. At this time, it is not necessary that the engagement between the engaging portions 41 and 41 and the peripheral edge portion of the notched portion 33 is released.

The part to be cut off together with the insertion piece 4 in the box body 2 is only the line surrounding portion 22a. That is, even if the insertion piece 4 is cut off, the degree of breakage of the box body 2 is small. Therefore, it is easy to reuse the opened packaging box 1 as an article storage box.
The vertical direction of the box body 2 may be the front-rear direction or the left-right direction. The length L1 may be longer than the length L2 or the length L3. The lid wall 3 is more securely fixed to the front wall 22 by gluing the insertion piece 4 to the lid main body 31 or packing the line surrounding portion 22a to the tongue piece 32 when packing the article.

FIG. 5 is a perspective view schematically showing the packaging box 1 according to Embodiment 2 of the present invention. FIG. 6 is a plan view schematically showing the blank 10 of the packaging box 1. 5 and FIG. 6 correspond to FIG. 2 and FIG. 3, but illustrations other than the upper portions of the packing box 1 and the blank 10 are omitted.
The packaging box 1 according to the present embodiment has substantially the same configuration as the packaging box 1 according to the first embodiment. However, the packaging box 1 according to the present embodiment does not include the inner partition 27, the connecting portion 11, and the adhesive margin 17, and instead of the cut line 5 and the fold line 61 of the first embodiment, the fold line 62 and the cut line. 63 is provided. Hereinafter, differences from the first embodiment will be described, and other parts corresponding to those of the first embodiment are denoted by the same reference numerals and description thereof will be omitted.

The fold line 62 corresponds to the composite fold line of the first embodiment.
The cut line 63 is an oval perforation, and in the upper side portion of the front wall 22, the support portion 282 (and thus the fold line 62 extends from the left side of the left cut 28 to the right side of the right cut 28. That is, it is provided so as to surround a boundary portion between the insertion piece 4 and the front wall 22. When the length L1 of the present embodiment is longer than the length of the fold line 62 in the left-right direction, the cut line 63 may be provided inside the support portion 282.

When opening the packaging box 1, for example, the user applies an external force to the portion surrounded by the cut line 63 (hereinafter referred to as the surrounding portion 22 b) from the outside of the packaging box 1 to the rear. Then, the cut line 63 is easily broken. That is, the user cuts off the insertion piece 4 from the front wall 22 together with the surrounding portion 22b. As a result, the fixing of the lid wall 3 to the front wall 22 is released. Therefore, even if the engagement between the engaging portions 41 and 41 and the peripheral portion of the notch 33 is not released, the lid wall 3 is easily opened.
The packaging box 1 as described above has an advantage that the opening procedure is simple, although the degree of breakage of the box body 2 at the time of opening is larger than that of the packaging box 1 of the first embodiment.

Embodiment 3. FIG.
FIG. 7 is a perspective view schematically showing the packaging box 1 according to Embodiment 3 of the present invention. FIG. 8 is a plan view schematically showing the blank 10 of the packaging box 1. 7 and 8 correspond to FIGS. 5 and 6.
The packaging box 1 according to the present embodiment has substantially the same configuration as the packaging box 1 according to the second embodiment. However, the packaging box 1 of the present embodiment is provided with a cut line 64 instead of the cut line 63 of the second embodiment. Hereinafter, differences from the second embodiment will be described, and other parts corresponding to the second embodiment will be denoted by the same reference numerals, and description thereof will be omitted.

The cut line 64 has cuts 28 and 28 and a perforation 65. The perforation 65 connects the lower ends of the cut lines 28, 28.
