Description

[Detailed description of the invention] [Industrial application field] This invention relates to a packaging paper box for pharmaceutical products, etc., and more specifically, it relates to a packaging paper box that is easy to open and whose safety is guaranteed. , used in the field of packaging.

[Prior Art] In order to make it easier to open a paper box sealed with tape or the like to ensure the safety of the contents, for example, Utility Model Publication No. 39310 of 1981 or Utility Model Publication of 1988 A device as described in Publication No. 156421 is known.

[Problems to be solved by the invention] Among the above-mentioned conventional technologies, in the former, a fingertip hook is provided as an opening means, but this fingertip hook is provided on the same plane. ,
The problem with this is that it is difficult to reach the tip of the toe.

On the other hand, in the latter case, a through-hole is provided that is large enough for the fingertip to be inserted as an opening means, and although this solves the above problem, the insertion piece of the top lid is inside the through-hole exposed to the outside. However, there is still a problem in terms of safety.

[Means for solving the problem] The paper box of this invention is a normal paper box in which the top cover and the upper part of the side wall are sealed with tape or the like, and a tear line surrounding the sealing tape is provided on the upper part of the side wall, and the paper box It has a structure in which two upper and lower folding lines are provided in the horizontal direction, and a sealing tape is pasted beyond the lower folding line.

[Example] Hereinafter, this invention will be described in more detail based on drawings showing an example of this invention.

Figure 1 is a perspective view of the paper box of this invention, and the structure of the paper box itself and the fact that a sealing tape 3 is attached between the top lid 1 and the front side wall 2 are the same as the conventional paper box. .

A tear line 4 surrounding the sealing tape 3 is provided at the upper part of the front side wall 2. The perforation line 4 may be a perforation as shown in the drawing, but it may also be a half cut. In the case of perforations, it is preferable that the cuts be relatively long. Although the shape of the tear-off piece 5 formed by the tear-off line 4 is arbitrary, it is preferable that the interval between the two vertical tear-off lines 4a, 4b is about the width of a finger used when opening the package.

Two upper and lower folding lines 6a, 6b are provided in the horizontal direction between the two cutting lines 4a, 4b. The folding lines 6a and 6b may be a folding line (Thomson), a half cut, a cut line, or a perforation, but it is preferable that the upper folding line 6a is a folding line and the lower folding line 6b is a half cut. preferable. When the folding lines 6a and 6b are opened, the lower folding line 6b becomes a peak and the upper folding line 6a becomes a trough, so that the center part 5a of the tear-off piece is
and the lower part 5b overlap to form a knob part. Therefore, it is preferable that the vertical length of the central separation piece 5a and the lower separation piece 5b is the same, and that the length is suitable for pinching with fingertips. Further, the positions where the folding lines 6a and 6b are provided are not particularly limited, but preferably close to the upper side of the front side wall 2.

The front end of the sealing tape 3 attached between the top lid 1 and the front side wall 2 extends to below the lower folding line 6b.

When opening the paper box of this invention, first push the lower part of the tear-off piece 5b inside the paper box body, then the cut-off line 4 on the lower side is cut off, the folding line 6b becomes a peak, and the folding line 6a becomes a valley. As a result, the cut-off piece 5a and the cut-off piece 5b overlap to form a knob portion. When this is pinched and pulled, the entire tear-off piece 5 is separated from the front side wall 2 of the paper box, and the paper box is unsealed.

[Effects] The paper box of this invention is extremely easy to open as described above while maintaining safety. In particular, even when a relatively hard item is stored, such as a press-through pack, there is a slight gap at the top of the paper box, so the folding line 6a,
If 6b is provided near the upper side of the front side wall 2, opening can be easily performed.

Another feature of this invention is that such excellent effects are achieved without adding any new processes compared to conventional paper boxes.
