DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging type packaging box capable of hanging and displaying products.

[0002]

2. Description of the Related Art Conventional hanging packaging boxes are, for example,
As disclosed in Japanese Utility Model Application No. 4-65410,
The box includes a box for storing a product, an upper lid piece formed at the top of the box so as to be openable and closable, and a hanging piece extending from the side of the box body on the opposite side to the upper lid piece. The hanging piece of the packaging box has a through hole for hanging, and is formed such that the paper piece extended from the side of the box body is folded so that the tip of the folded portion is located inside the box body. The folded portion is provided with a locking piece that is inserted into an insertion slit formed in a ruled line portion between the upper lid piece and the insertion piece. The locking piece is formed at a substantially central portion of the folded portion through an arc-shaped cut line.

[0003] Then, the insertion piece of the upper lid piece is inserted into the box body, the locking piece of the hanging piece is slightly raised from the cut line, and is inserted into the slit of the upper lid piece, thereby engaging with the slit of the upper lid piece. The upper piece is locked by engaging the stop piece and not being opened.

[0004]

In the case of the above-mentioned prior art, since the upper lid piece is held only by the locking piece, stress concentrates on the cut end of the cut line in which the locking piece is formed, and the engaging portion is not engaged. The end of the cut line that forms the notch is easy to tear,
The strength of the locking piece itself was also weak. Therefore, the holding force of the locking piece is also weak, and the upper cover piece is easily lifted up by the impact force due to the vibration of the box or the movement of the contents, or the cut line is easily torn open. In addition, when the upper cover piece is lifted, dust and foreign matter easily enter the inside of the box, which is a problem in terms of safety and health.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a hanging type packaging box in which the lid is not easily opened and the lid is not easily detached even by vibration or the like. Aim.

[0006]

Thereafter, as shown in FIGS. 1 and 3, the locking piece 70 is inserted into the locking hole 40 of the insertion piece 35. As a result, as shown in FIG. 3, the locking notches 43 at both ends of the locking hole 40 are engaged with the engaging projections 7 at both ends of the locking piece 70.
2 and the locking piece 70 and the upper lid piece 30 are held unopened.

In the hanging packaging box of this embodiment, the locking piece 70 and the connecting piece 71 are formed above the side surface 18, and the upper lid piece 30 can be reliably held by a simple structure of cutting out the locking piece 70 and the connecting piece 71. . Further, since the locking notch 43 is provided, the engagement between the locking hole 40 and the locking piece 70 can be performed easily and reliably.

Next, a second embodiment of the hanging type packaging box of the present invention will be described with reference to FIGS. Here, the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted. In this embodiment, a locking piece 80 having an arcuate upper end is provided at the center of the edge of the insertion piece 35,
At both ends of the locking piece 80, locking projections 82 are provided.
Further, the folded portion 61 of the hanging piece 60 is extended so as to be located inside the box body, a locking hole 84 is formed in the extended central portion, and locking notches 86 are provided at both left and right ends. I have.

Further, the hanging piece 60 has a fold line 62.
The suspension holes 64 and 65 are formed at symmetrical positions with respect to. Further, a slit 88 is formed in the upper central portion of the side surface 18 of the folded portion 61 facing the locking piece 80 in the vertical direction.

The method of assembling the hanging-type packaging box according to this embodiment is performed before or after storing the product in the box.
Glue 66 is applied to two places on the back surface of the folded portion 61 of the box forming piece 10, and the fold line 62 is folded forward to glue the back surface of the folded portion 61 to the back surface of the side surface 18. In this state, the hanging hole 6
4 and the hanging hole 65 face each other and overlap.

Further, after storing the product, the upper flap 51 is folded forward at a right angle at the folding line 53, and the upper lid piece 30 is folded at the folding line 32 as shown in FIG. The stop piece 80 and the insertion piece 35 are inserted into the inside of the side surface 18, and at the same time, the locking piece 80 is inserted into the locking hole 84. In addition, the notch 88 of the side surface 18 makes the locking piece 80
4 makes it easy to insert. As a result, as shown in FIG. 6, the locking notches 86 at both ends of the locking hole 84 and the locking projections 82 at both ends of the locking piece 80 engage with each other, and the locking piece 80
And the upper lid piece 30 is held so as not to be opened.
