Description

The present invention relates to a sticking box on which a decorative paper is stuck on the surface.

The sticking box is made by sticking decorative paper on the surface of the fabric box, and since it is possible to obtain a sticking box with various appearances by changing the material and color pattern of the decorative paper, it is used for packaging various products. It is widely used as a box (packaging box) (Paper Document 1).

The dough box is usually formed by bending a core material made of thick paper such as cardboard or corrugated cardboard. The decorative paper usually consists of a single sheet of paper having a shape corresponding to the unfolded shape of the cloth box. For example, when the dough box is composed of a rectangular base (bottom) and a rectangular side wall that stands up from its four sides, the decorative paper is extended to the rectangular corresponding to the base of the dough box and its four sides. , It has a shape in which four rectangles having the same width as the side wall portion of the dough box and having a height larger than the side wall portion are combined. Since the decorative paper has such a shape, when the decorative paper is adhered to the outer surface of the fabric box, the decorative paper protrudes from the upper part of the side wall portion of the fabric box. This protruding portion (folded portion) is bent inside the dough box and attached to the inner surface of the side wall portion.

When the packaging box consists of a box body and a lid to be placed over the box body, a recess (close) for finger hooking may be formed in the center of the lower end (opening side end) of the side wall portion of the lid. In particular, in the case of a lid that covers the entire box body, providing a recess at the opening-side end of the side wall of the lid makes it easier to put a finger on the lid, and the lid can be easily removed from the box body.
In a sticking box in which such a recess is formed in the side wall, a boundary between the opening side end of the side wall and the recess so that when the decorative paper is attached to the side wall, the decorative paper can be folded back along the recess. A cut is made in (2 places) to divide the folded part.

Jitsuto 3072369 Gazette Japanese Unexamined Patent Publication No. 2010-064351

Conventionally, it has been common to make a linear cut (slit) in the decorative paper at the divided portion of the folded portion. In this case, the folded piece of the decorative paper from the opening side end of the side wall portion and the folded piece from the edge of the recess overlap with each other, so that a thick overlapping portion is generated, which makes the appearance worse and a gap between the box body and the lid. There was a problem that it would occur.
Further, Patent Document 2 describes a folding machine that automatically attaches decorative paper to a fabric box. The folding mechanism of this folding machine is a folding portion with respect to one side wall portion of the fabric box. Is bent at the same time and pressed against the inner surface of the side wall portion. Therefore, it cannot be used when the folded pieces overlap as described above.

Here, a lid having a recess for finger hooking on the side wall has been described as an example, but also in the case of the box body, the recess is provided on the side wall in order to make it easy to take out the articles contained therein from the box body. In this case, there was a problem similar to that of the lid. Further, there is a similar problem not only when a recess is provided in the side wall portion in order to enhance the functionality of the pasting box, but also when a recess is formed in the side wall portion in order to enhance the design of the pasting box.

The problem to be solved by the present invention is to clean the folding back of the decorative paper in a sticking box having a recess at the end on the opening side, and in the case of a sticking box with a lid, to achieve high-precision occlusion between the box body and the lid. It is to make it possible and to make the folding machine usable.

The present invention made to solve the above problems
A pasting box composed of a dough box having a recess at the opening end and one or more sheets of decorative paper attached to the surface of the dough box.
The slits formed at the positions corresponding to both ends of the recesses of the decorative paper are both V-shaped slits.

In the above configuration, since the slits formed at both ends of the recess of the decorative paper are both V-shaped, the folded piece bent at the outer opening end of the recess and the folded piece bent at the recess. Can be prevented from overlapping with.
Further, since the folding piece at the opening end on the outside of the recess and the folding piece at the recess can be bent at the same time, a folding machine as described in Patent Document 2 can be used.

When the dough box has a polygonal bottom plate and a plurality of rectangular side wall portions rising upward from a plurality of sides of the bottom plate (that is, when the pasting box is a box body), the opening end is said to be said. It is the upper end of the side wall. Further, when the dough box has a polygonal top plate and a rectangular side wall portion that rises downward from a plurality of sides of the top plate (that is, when the pasting box is a lid), the open end is It is the lower end of the side wall portion. When the recess is a recess for finger hooking, the recess is usually provided on two opposing side walls.

When the dough box has the above configuration, the decorative paper has a shape corresponding to the bottom plate or top plate of the dough box and a shape corresponding to the side wall portion, and further has a shape in which a folded portion bent at the upper end or the lower end of the side wall portion is added. The V-shaped slit is formed in a folded-back portion that is bent at the upper end or the lower end of the side wall portion having a recess.
It should be noted that slits are generally formed not only at the portions corresponding to both ends of the recess but also at the portions corresponding between both ends of the recess, but the slits may be linear and V. It may be in the shape of a letter.

Further, in the pasting box having the above configuration, it is preferable that the recess is trapezoidal and a linear slit is formed at a portion corresponding to the boundary between the hypotenuse and the upper bottom.
In this case, it is more preferable that the linear slit is a straight line perpendicular to the opening end on the outside of the recess.
Further, it is preferable that one of the two sides defining the V-shaped slit is perpendicular to the open end of the dough box.

According to the present invention, even if the sticking box has a recess at the end on the opening side, the folding back of the decorative paper in the recess can be cleaned. Therefore, in the case of a sticking box with a lid, the box body and the lid are highly accurate. Allows for a good occlusion. Further, since the folded piece of the opening end on the outside of the concave portion and the folded piece of the concave portion can be bent at the same time, the decorative paper can be attached using the folding machine.
