DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper packaging box which can be used as an accumulation box for products after opening a box containing a large number of individually packaged products.

[0002]

As this type of packaging box, a front and rear wall plate for forming a box body so that the opened box body can be displayed and stored in an aligned state as a collection box as it is. And, a strip-shaped fastener with two upper and lower perforations is applied to the four wall boards of both side wall boards, the fastener is pulled from a cut in the middle, and the box is opened by separating the perforations of the four peripheral wall boards. Are known.

[0003] In such opening with a zipper, the zipper becomes longer as the separation proceeds, which makes the zipper easy to cut in the middle or the perforation does not go as expected. Often takes time. Further, the fastener is liable to become garbage after being opened, and there is also a problem that the perforation is easily cut and broken due to bending of the fastener when the fingertip is hooked on the fastener when the box body is grasped as a packaging box before opening.

Further, a cut line formed by a single perforation is formed around the four wall plate of the box, and the opening clue of the cut line is formed on the plate surface by forming the cut line of the side wall plate downward. In some cases, the protruding piece is formed by pushing it in, and the finger is inserted into the gap created to open it.However, in such a packaging box, all the cut lines in the side wall plate are cut off and the protruding part is cut off. The protruding part must be pushed deeply into the upper part of the part until the cue by the fold is made, and if there is not enough pushing room inside the box, the product inside will be an obstacle to pushing,
Opening clues are less likely to form. Therefore, it may not be used for a packaging box for storing a product individually packed in a paper box in a full box.

[0005] The packaging box having the above-mentioned opening means and also serving as an accumulation box is increasingly being used for medical products and pharmaceuticals in addition to individually packaged confectionery and retort foods. In pharmacies and dispensing rooms, medicines are often stored in boxes, so they can be kept in their original storage condition after opening and can be easily taken out of packaging. The box is handy. In particular, in the case of individually wrapped products with heavy contents such as drip solutions, cardboard can be used for the box, so it is very convenient.However, in the past, the box could be damaged unless opened carefully. Or, because of the difficulty in forming the opening cue, it is desired to have a structure that can be opened as easily as possible and furthermore the remaining amount can be easily confirmed.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a packaging box having an opening line with one perforation on at least a three-wall plate of a box body.
The opening clues on the side of the box can be easily formed by the deformation of the corners, and the box can be easily opened simply by pulling or pushing up the top of the box from the deformed portion. It is an object of the present invention to provide a packaging box which can be stored in a box as it is while keeping the alignment, and which also serves as an easy-to-open stacking box.

[0007]

SUMMARY OF THE INVENTION The present invention according to the above object has an opening line formed by perforations in a three-walled or four-walled plate of the front and rear wall plates and one of the side wall plates. A packaging box formed by continuously forming perforations of the front and rear wall plates of the line in the same direction, wherein the corner of the box body of the one side wall plate is
It is formed so that perforations can be separated by partial pressure deformation by fingers, so that the upper part of the box can be separated and opened upward from the opening line. The perforations of the front and rear wall plates of the continuously formed opening line are formed to be inclined from the upper corner end of the boundary with the other side wall plate to the perforation end of one side wall plate, respectively.
The upper part of the box is configured so that it can be separated and opened upward from the opening line while keeping the other side wall plate as it is.

The present invention is also directed to a sewing machine which is connected to the perforated line and partially weakened vertically on a plate surface above the perforated line of the one side wall plate, and a lower part of the opening line of the front and rear wall plates. The eyes are formed to be detoured downward, so that the corners of the box can be easily deformed under pressure.

Further, in the present invention, a weakening line is formed along the corner of the box between the plate surface on the perforation of the one side wall plate and the plate surface on the perforation below the opening line of the front and rear wall plates. It is intended to be configured vertically so as to easily form the pressure deformation of the corner of the box body, and to form the perforation of the one side wall plate upward and to form the front and rear wall plate. A weakening line is formed obliquely toward the upper corner on the plate surface above the perforation below the opening line, so that the box corner can be easily deformed under pressure.

[0010] The perforation line of the opening line in the above configuration is preferably a perforation shape having no jagged edges at the opening edge because it is used as an accumulation box after opening. The weakening line is preferably a ruled line, but may be a perforation in some cases, and the cover plate of the box body is not limited to a one-sided cover but may be a double-sided cover.

In the present invention having the above-described structure, the opening cue is formed only by partially pressing and deforming the corner of the box body with the finger. Only requires pulling or pushing up the upper part of the box from the deformed part, and the perforation of the opening and closing line is easily cut off and opened, so the stored product in the box becomes an obstacle to pushing in and the opening cue The opening can be performed extremely easily without being affected by the individually wrapped product or the storage state without making the formation of the package difficult.
