Description

[Detailed Description of the Invention] The present invention relates to an improvement in a packaging box with perforations for opening.

Paper boxes used to package paper towels, paper napkins, tissue paper, etc. usually have perforations on at least one side for opening the box, and various ways to make opening the box easier have been proposed and put into practice. has been made into However, a common drawback of these conventional products is that the excessive force exerted on the box at the start of opening often causes the surface of the box to be cut beyond the perforations, spoiling the aesthetic appearance of the packaging box. Ta.

The present invention provides a novel packaging box that eliminates the above-mentioned drawbacks by having a double box wall at the beginning of opening.

The packaging box of the present invention can be made by three-dimensionalizing a cardboard material having a developed shape as shown in FIG. 1, for example. In the figure, A is a top plate, B is a front plate, C is a glue plate for joining top plate A and front plate B, D is a back plate, E is a bottom plate, F and G are side plates, and H is a It is a glue board.
At the center of the lower end of the glue plate C, a tab 1 for opening the box is formed in the shape of a tongue. There are two perforations 2 in an inverted V-shape from both base ends of the knob 1 toward the boundary between the gluing plate C and the top plate A, and then to the boundary between the top plate A and the back plate D. Two perforations 3 are made parallel to each other, and a press line for bending the knob 1 is provided between both base ends of the knob 1 (that is, between the starting ends of the two perforations). 4 has been applied. At the top of the front panel B, there are two perforations 2 and 2 in the shape of an inverted V.
A notch 5 (a line or elongated groove that penetrates to the back surface) is made to connect both starting ends of the perforation of the book.
These two perforations 2, notches 5 and front plate B
The trapezoid formed by the upper side is approximately congruent with the trapezoid formed by the two perforations 2 in the gluing plate C, the press line 1, and the boundary line between the gluing plate C and the top plate A. be.

The three-dimensional construction of the cardboard material shown in FIG. 1 may be carried out using any procedure as long as the final step is to join the top plate A and the front plate B using the glue plate C. In the final step, the gluing plate C is bent and glued so as to overlap the upper surface of the front plate B as shown by the arrow in FIG. The adhesive is
The adhesive is applied to the back surface of the slat plate C and/or the upper surface of the front plate B, for example, continuously or intermittently, over substantially the entire width, as shown by the two-dot chain line in FIG. In this way, the packaging box of the present invention having an appearance as shown in FIG. 3 is assembled.

As is clear from the above description, in the packaging box shown in FIG. 3, the upper wall of the front plate has a double structure;
Roughly overlap perforation 2 of gluing plate C (3rd
(Although not visible in the figure), there is a perforation 2 on the front plate B (in other words, the perforation is formed through the double wall), and the bending press line 4 of the knob 1 is approximately overlapped. (not visible in Figure 3)
Notch 5 is present.

The packaging box shown in FIG. 3 is opened by first bending the tab 1 along the press line 4, then pinching it with the fingers and pulling it upward. As mentioned above, the area around the knob 1 is reinforced with a double wall structure, and the perforation 2 is provided through the double wall, and there is a front plate between the starting ends of the perforations. Since the notch 5 penetrating B is provided in advance, by pulling up the knob 1, the wall can be easily removed without causing any damage to the wall.
The box can be opened to the state shown in FIG.
In Fig. 4, C' is the cut-off glue plate, A' is the cut-off top plate, and B' is the cut-off top plate.
The front plate is attached to C' and separated, 2' and 3' are the perforations that are separated, 5' is the cut that is separated, and 6 is the contents of the packaging box.

After opening the box and taking out the required amount of contents, remove the pulled-up tongue-like object (1, C′,
(consisting of B' and A') functions as the lid of the packaging box. This lid is closed by inserting the knob 1 into the inside of the box (on the back side of the front panel B).
Useful to protect contents from dust and contamination.

As described above, the packaging box of the present invention has reinforced double walls, so there is no damage to the surface when the box starts to be opened, and there is no possibility of damage, especially in the case of a packaging box intended for interior goods. Therefore, the practical value is high because the design effect does not deteriorate due to this.
