Description

  The present invention relates to a packaging box for packaging an object to be packaged such as toilet paper or kitchen towel.

  2. Description of the Related Art Conventionally, a packaging bag in which an object to be packaged such as toilet paper or kitchen towel is packaged with a package film is known. Since the packaging bag generally uses a soft and high strength package film, it has not been easy to open. For this reason, the packaging bag has a problem that the package film is torn when the consumer tries to open the bag forcibly, the appearance is poor, and the packaged body is difficult to store.

  Therefore, a pair of side plates and end plates are connected to form a square cylindrical peripheral wall, a pair of end plates are arranged vertically, a lid is connected to the front end of one side plate, and the rear wall is closed A holding piece is continuously connected to the front end of the other side plate, a crease line and a score line are formed in the holding piece to form a cut portion, and the holding space is not limited by the holding piece when storing articles. The capacity state, the medium capacity state in which the holding piece is folded so as to be wound along the crease line, and the first spacer are formed, and at least a part of the cut line is cut and the cut portion is folded so as to be wound along the crease line. There is known a packaging box in which a spacer is formed and a small capacity state in which a second spacer is fitted between a first spacer remaining below and a rear wall can be selected (see Patent Document 1).

  According to the packaging box described in Patent Document 1, since the package is packaged with paper, cardboard, or the like that is harder than the package film, it is easy to open, so the appearance after opening does not deteriorate. Moreover, the packaging box of the invention described in Patent Document 1 can be provided with cut lines and crease lines, so that the accommodation space of the packaging body can be made variable according to the accommodation volume of the packaging body. However, in the storage space, the partition position for storing the packaged body is changed inside the packaging box, and the whole packaging box is not downsized. Therefore, there is a drawback in that a useless space in the entire packaging box increases as the packages are sequentially taken out.

  Therefore, it is a packaging box used for packaging a packaged body made of raw confectionery such as a short cake, and a dividing line for dividing the box body vertically into the approximate center in the height direction of the peripheral wall of the box body Is provided along the circumferential direction (see Patent Document 2).

A case where the consumer takes out four toilet papers P from the first-stage packaging unit 10a will be described as an example.

First, in the state shown in FIG. 7, when the four toilet papers P are taken out from the packaging box 1a, the consumer cuts the upper surface wall portion 300 by making a cut along the perforation line A15.
Next, the consumer makes a cut along the perforation lines A11 to A14, and removes the handle T from the attaching / detaching portions 420a and 520a.
Next, the consumer folds the left wall portion 400 and the right wall portion 500 so as to be the upper lid of the second stage packaging portion 1000a. That is, the consumer folds the left wall portion 400 and the right wall portion 500 to a position in contact with the bottom hole portion 600 via the crease lines B11 and B12.
Next, the front wall portion 100 and the rear wall portion 200 are folded to the inner wall side via the crease line B13 and the crease line B14, and the handle T is attached to the detachable portions 1420a and 1520a of the second stage packaging portion 1000a.
By the above deformation operation, the packaging box 1a is reduced in size by reducing the volume of the four toilet papers P as shown in FIG. 8, and is packed in the remaining packaging parts 1000a and 2000a. The toilet paper P that has been used can be continuously sealed.

  As described above, according to the packaging box 1a according to the first modification, the same effect as that of the packaging box 1 according to the first embodiment is exhibited, as compared with the packaging box 1 according to the first embodiment. The number of perforation lines and crease lines is small, and the deformation operation for miniaturization is easy.

  In addition, the packaging box 1a includes attachment / detachment portions 420a, 520a, 1420a, 1520a, and 2420a that allow the handles T for carrying the packaging box 1a to be detachably attached to the left wall portion and the right wall portion of the packaging portions 10a, 1000a, and 2000a. , 2520a. Therefore, every time the consumer deforms and downsizes the packaging box 1a via the handle T, the consumer always attaches the packaging box 1a to the left wall part and the right wall part of another packaging part. Can be portable.

The scope of the present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the number of toilet paper that can be accommodated in the packaging box is not limited to the number exemplified in the first embodiment and the first modification. In other words, in Embodiment 1 and Modification 1, each toilet has a structure that can store two toilet papers. When two trays are used, a total of four toilet papers are stored, but each toilet has three toilet papers. 2 stages (6 total) or 3 stages (9 total), or 2 stages (8 rolls in total) that can accommodate 4 toilet paper in each stage. Of course it is also possible.

Moreover, in Embodiment 1 and Modification 1, each packaging part is configured to be connected vertically, but may be configured to be connected horizontally.
Furthermore, although toilet paper was illustrated as a packaged body, it may be another household thin paper wound in a roll shape such as a kitchen towel, or may be other than household thin paper.
