Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a packaging box in which the lid flap can be bent and fixed to the outer surface of the side wall plate after the box is opened.

Problems to be solved by conventional techniques and ideas During the distribution process, there are cases where a large number of packaging boxes used for transporting products are opened to transfer products, take parts in and out, etc. In this case, the lid flap of the packaging box gets in the way of the work, so countermeasures have been taken such as cutting off the lid flap or bending the lid flap and hanging it with a band so that it can be fixed to the outside surface of the side wall board. However, all of these measures have the drawback of requiring a great deal of effort.

The present invention provides a packaging box in which the lid flap can be bent and immediately fixed to the outer surface of the side wall board after opening the box.

Means for Solving the Problems In order to achieve the above problems, the packaging box of the present invention is a packaging box in which a lid flap is connected to the side wall plate via a fold line, and two notches are provided from the side wall plate to the lid flap. When the lid flap is folded back towards the outer surface of the side wall plate along the fold line and the notched part sandwiched between the two notches is pushed down to the outside or inside of the side wall board, the fallen notch part will be folded between the notches. It is formed so that it can be locked.

In the present invention, it is preferable to provide an appropriate number of two-striped notches depending on the number of lid flaps that need to be fixed. In this case, in consideration of workability, etc., the two notches may be placed on the inside of the packaging box or placed on the outside. All you have to do is choose which one to defeat. In general, in the above case,
It is more convenient to tilt it outward. Furthermore, as shown in 41d in Figs. 1 and 2, depending on the shape of the two notches, the lid flap can be fixed even if it is folded to the inside or outside of the packaging box. . The width of the two cuts is optional, but
It is preferable that one finger can fit inside.

Embodiment An embodiment of the packaging box of the present invention is shown in FIGS. 1 and 2.

This packaging box includes two pairs of lid flaps 11, 12, two pairs of side wall plates 21, 22, and two pairs of bottom plates 31, 32.
and one glued piece 51.

This example packaging box has side wall plates 21, 21, 22, 22.
There are two notches 41a, 41b, 41c, 4 between the
1d is provided, and cut portions 42a, 42b, 42c, 42 sandwiched between these two cuts
d, the lid flaps 11, 11, 12, 12 are connected to the side wall plate 2 through the fold lines 110, 110, 120, 120.
1, 21, 22, 22, and then folded to the outside or inside of the side wall plates 21, 21, 22, 22, these cut portions 42a, 4
2b, 42c, and 42d can be locked between the notches. That is, in Figure 2,
The cut portion 42a has a portion below the fold line 110 that is larger than the minimum dimension between the cuts 41a (located above the fold line 110). Notch part 4
2b is the minimum dimension between the notches 41b (broken line 120
12)
It has above 0. The cut portion 42c has a portion below the fold line 110 that is larger than the minimum dimension between the cuts 41c (located above the fold line 110). As shown in FIG. 2, the notch portion 42d is shifted laterally along the fold line 120, and the right end of the notch portion 42d is such that the upper part of the fold line 120 is on the inside than the lower part, and the cut part 42d In the left end portion of 42d, the upper portion of the broken line 120 is located outside the lower portion.

Function and Effect of the Invention Therefore, when opening the packaging box of the present invention containing a product (not shown) and carrying out work to take out and take out the product, the lid flaps 11, 11, 12, 12 should be aligned with the fold line 1.
Side wall plate 2 via 10, 110, 120, 120
1, 21, 22, and 22, and then use a fingertip to insert the cut portion 42a on the outside of the side wall plate 21, the cut portion 42b on the inside of the side wall plate 22, and the cut portion 42c on the outside of the side wall plate 22. is on the outside of the side wall plate 21, and the notch part 42d is on the outside of the side wall plate 22. When the notch part 42a is folded down to the outside of the side wall plate 22, the notch part 42a is between the notches 41a, the notch part 42b is between the notches 41b, and the notch part 42 is
c is between the notches 41c, and the notches 42d are between the fold lines 1
The ends of the portions below 20 are respectively locked on the same end side of the notch 41d.

According to the present invention, the lid flap can be immediately tilted and fixed to the outside or inside of the side wall plate with just a light fingertip, and work efficiency is greatly improved.

Furthermore, according to the present invention, it is only necessary to make a slight cut in the box board, so manufacturing is extremely inexpensive.
Furthermore, there is no risk of degrading the appearance of the box itself.
