Description

The present invention relates to a packaging paper box such as a cardboard box, and more particularly to a packaging paper box that can easily peel off an adhesive tape for sealing such as an OPP adhesive tape, a kraft adhesive tape, or a cloth adhesive tape used at the time of packaging.

In the conventional cardboard box, a rectangular cylindrical body is formed by four body wall parts including an opposing first body wall part and an opposing second body wall part, and is formed at upper and lower edges of the first body wall part. The outer flap is connected, and the inner flap is connected to the upper and lower edges of the second body wall portion.

When packaging, the lower inner flap and outer flap are folded in advance to form the bottom, and in this state the product etc. are stored inside the box, and then the upper inner flap and outer flap are folded, Generally, a sealing pressure-sensitive adhesive tape is bonded from the butted portion to the upper portion of the second body wall portion.

In order to open the packaged cardboard box in this way, the end of the sealing adhesive tape is raised by raising a nail or the like strongly at the end of the sealing adhesive tape at the upper part of the second body wall. Is gripped with a finger and peeled off, but there is an inconvenience that it takes time.

In particular, OPP (stretched polypropylene) pressure-sensitive adhesive tape, which has been widely used in recent years as an adhesive tape for sealing because of its low cost, is relatively thin because it has excellent strength, and its adhesive strength is high. It is very difficult to wake up a part.

It is also possible to run the cutter knife etc. at the butt of the outer flap to cut the sealing tape for sealing and open the cardboard box. There is a risk of damaging products and the like, and careful work must be taken.

In addition, even if the cardboard box is opened using a cutter knife or the like in this way, when the cardboard box is recycled and repulped, it is necessary to remove the sealing adhesive tape remaining in the cardboard box. There is no change in the need to peel off the material.

Therefore, conventionally, a corrugated cardboard box has been known in which a separable area slightly larger than the width of the sealing adhesive tape is formed in the upper central portion of the second body wall so that the sealing adhesive tape can be easily peeled off. (See Patent Document 1).

In this conventional cardboard box, when the adhesive tape for sealing is bonded and packaged from the abutting portion of the outer flaps to the upper portion of the second body wall portion, the end of the adhesive tape is positioned in the separable region. Adhere.
When opening, the finger is pushed into the box from the push-in part to raise the separable area, and by holding the finger with the finger and pulling up the separable area, the sealing tape is sealed. It is intended to be peeled off.

Utility Model Registration No. 3164053

In this conventional cardboard box, it is possible to grasp the separable area and peel off the sealing adhesive tape, so that it takes time and effort to raise the end of the sealing adhesive tape by placing a nail or the like on the sealing adhesive tape. It is possible to easily peel off the sealing adhesive tape without need.

However, at the time of opening, the upper part of the second body wall part is completely separated by the separable area, so that a hole slightly larger than the width of the sealing adhesive tape is opened at the upper part of the second body wall part.
Also, in order to grasp the separable area, it is necessary to push the finger from the push-in part to the inside of the box, and when the can etc. are packed in the box without a gap, the finger cannot be pushed in There is also a problem that the separable area cannot be grasped.

After opening the cardboard box, it is necessary to be able to reuse it from the viewpoint of ecology. In this case, however, the adhesive for sealing is removed by removing the separable area as before. If a hole that is slightly larger than the width of the tape is opened, it will not be possible to bond the sealing tape for reuse (reuse), and the hole will weaken the strength of the second body wall, making it a packaging box. The problem that it becomes impossible to use arises.

The present invention has been made to solve the above-described problems. When opening, the adhesive tape for sealing can be rolled up without trouble, and the raised portion is grasped with a finger. It is an object of the present invention to provide a wrapping paper box in which the sealing adhesive tape can be easily peeled off.

In order to solve the above problems, the present invention is configured as follows.

The wrapping paper box of the present invention (Claim 1) is characterized in that an easily peelable processing group for the sealing adhesive tape is formed on the upper surface of the central portion in the width direction of the second body wall portion.

When packaging with a wrapping paper box, products etc. are stored inside the box, then the upper and inner flaps are folded and formed on the upper surface of the second body wall from the butted portion of the outer flaps The adhesive tape for sealing is adhered to the easily peelable processed group.
At this time, since the pressure-sensitive adhesive tape for sealing is located in the easy-peeling group, the pressure-sensitive adhesive tape for sealing is attached to the easy-peeling group in an easy-to-peel state.
Thus, when opening, the sealing adhesive tape can be lightly raised with a toe or the like within the easy-peeling processing group, and the sealing adhesive tape can be easily peeled off by grasping it with a finger.

The easy-peeling group includes a large number of small hole groups, a large number of convex part groups, a large number of concave part groups, a large number of cut groups, or a combination thereof (Claim 2).

Further, when a recess forming auxiliary part (for example, a cut line or a hole) is formed in the wall body in the easy peeling processing group (Claim 3), the sealing adhesive tape is removed from the surface of the box by the concave forming auxiliary part. If it is pushed inward and recessed, the adhesive tape for sealing can be deformed and floated.
Therefore, it can be easily peeled off without the troublesome trouble of rolling up the adhesive tape for sealing with a toe or the like.
Unlike the conventional case, it is not necessary to push the finger into the inside of the box, and even if the can of the contents is packed without any gaps, it is only necessary to push the dent forming auxiliary part toward the inside of the box and dent it to seal. The tape can be floated, and the sealing tape for sealing can be easily grasped with a finger.

It is preferable that the dent formation assisting portion is visible from above the sealing adhesive tape. Therefore, for a packaging paper box having a structure in which the dent forming assisting portion is formed, a transparent OPP adhesive tape is used as the sealing adhesive tape. It is suitable for the case.

The easy-peeling process group may be formed on an easy-peeling surface obtained by applying a release agent having a component structure with excellent peelability to the wall surface. In this case, the easy-peeling process group and the easy-peeling surface The adhesive tape for sealing can be easily peeled off by both easy peeling actions.

As described above, according to the present invention, since the sealing adhesive tape can be easily peeled off, the opening operation is facilitated, and the sealing adhesive tape is not required to be removed when repulping. Therefore, recycling becomes easy.

Also, even when the wall surface may be peeled off by the sealing tape when opening, unlike the conventional case, a large hole will not be opened in the upper part of the second body wall part, so as a packaging box Can be maintained and can be reused.
