Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tissue paper storage box, and more particularly to a tearing perforation for a tissue extraction opening formed on the upper surface of the storage box.

[0002]

2. Description of the Related Art Generally, a tissue paper storage box accommodates tissue papers that are stacked in a folded state, and when used, the tissue papers can be continuously taken out one by one from an upper outlet. There is. In this case, as shown in FIG. 5, the outlet has a rectangular perforation 52 formed on the upper surface of the tissue paper storage box 50 in a product state, and the unsealing piece surrounded by the perforation 52. It is formed by cutting out 51. The arcuate cutout 51a formed at the end of the unsealing piece 51 is a fingertip insertion portion for inserting a finger when tearing the unsealing piece 51.

[0003]

However, in the case of the conventional tissue paper storage box 50, the opening piece 5 is used.
When 1 is cut along the perforation, there are problems that the edges of the cut end become uneven and the appearance and touch are poor. In addition, the perforations do not cut cleanly from one cut to the next, and the top layer of the surrounding paper with color and design is thinly peeled off, causing a problem such as the appearance around the cut edge becoming worse. Was there.

Therefore, a main object of the present invention relates to a perforation forming perforation formed on the upper surface of the tissue paper storage box, and when the opening piece is cut off, the surrounding paper is not thinly peeled off, and It is intended to provide a tissue paper storage box with a beautiful cut edge around the entire circumference.

[0005]

In order to solve the above-mentioned problems, the present invention stores tissue paper in a superposed state,
In a tissue paper storage box in which a tearing perforation is formed along the outlet shape for forming a tissue paper outlet in the upper surface portion thereof, the tearing perforation is cut along the entire circumference thereof and a tie. It is formed as a double perforation with an inner perforation and an outer perforation consisting of parts, and the cutting line when dehiscing is such that the cut parts of the inner perforation and the outer perforation are alternately moved back and forth. It is a feature.

In this case, preferably, the outlet is divided into an intermediate portion and both end portions in the longitudinal direction, and in the intermediate portion, both the inner perforation line and the outer perforation line are the length of the cut portion and the tie portion. While substantially the same, the inner perforation and the outer perforation are formed substantially evenly so that the cut portions of each perforation have a zigzag arrangement, while the cut portions are formed at both ends in the longitudinal direction. The inner perforation is formed while being dominant, and the outer perforation is formed so that the cut portion of the outer perforation is located outside the tie portion of the inner perforation.

[0007]

In the present invention, the dehiscence perforation is formed as a double perforation consisting of an inner perforation and an outer perforation consisting of a cut portion and a tie portion all around the perimeter of the dehiscence perforation. Lines alternate between the cuts of the inner and outer perforations.
Therefore, in order to form the tissue paper outlet, when one end side of the unsealing piece is picked up and the perforation is torn open, the cutting line alternates between the cut portion between the inner perforation and the outer perforation. , It is cut cleanly around the entire circumference of the outlet, and the appearance is not damaged. In addition, the edge portion of the take-out port does not have irregularities and has a smooth feel.

In the case of the second perforation forming example,
At both ends in the longitudinal direction, since it is difficult to apply a force particularly in the direction along the perforations, the surface layer of the surrounding design paper tends to be peeled off from the tie portion as a starting point, but in the present invention, the cut portion is The inner perforation is formed while being dominant, and the outer perforation is formed so that the cut portion of the outer perforation is located outside the tie portion of the inner perforation, so the first starting point of tearing is The dehiscence can be facilitated and the cut can be reliably and neatly cut along the perforations. On the other hand, in the middle part, the inner perforated line and the outer perforated line are set to have the same lengths as the cut part and the tie part, and the cut parts of the respective perforations are arranged in a zigzag arrangement so that the cut parts are arranged in a zigzag pattern. To form the outer perforations almost evenly,
When tearing up the perforation by picking up one end of the unsealing piece and pulling it up, the cutting line surely and beautifully cuts while the cutting line alternates between the cut parts between the inner perforation and the outer perforation. Will be done.

EXAMPLES The present invention will be described in detail below based on examples.
FIG. 1 is a perspective view of a tissue paper storage box according to the present invention, and FIG. 2 is an enlarged plan view of an outlet portion. On the upper surface 1A of the tissue paper storage box 1, tearing perforations C are formed along the shape of the outlet for forming the outlet for the tissue paper. The inside in which the perforation C for tearing is formed becomes the unsealing piece 2, and the unsealing piece 2 is removed at the start of use, and an opening for taking out the tissue paper contained therein is formed.

As shown in detail in FIG. 2, the tearing perforation C is formed as a double perforation along the entire circumference of the outlet according to the present invention by an inner perforation 20 and an outer perforation 21. Has been done. In the following, in more detail, in the case of the present embodiment, the take-out port is connected to the intermediate portion 11
And the both end portions 10 in the longitudinal direction are divided, and the formation mode of the double perforation is changed in each region. First, in the intermediate portions 11 and 11, as shown in FIG. 3, the inner perforations 20 and the outer perforations 21 are cut into the lengths M ₁ and M _{2 of the} cut portions 20b and 21b and the tie portions 20a and 21.
While the lengths T _{1 and} T _{2 of a} are the same, the inner perforations 20 and the outer perforations 21 are evenly formed so that the cut portions 20b and 21b of the perforations have a zigzag arrangement.

In this case, the cut portions 20b, 21b
Lengths M ₁ and M ₂ and lengths T of the tie portions 20a and 21a
Specifically, the length of _1, T ₂ is 0.7 mm to 1.5 mm
It is good to set the degree. In the illustrated example, the cut portions 20b of the inner perforation 20 and the outer perforation 21 are
A double perforation is formed with the lengths M ₁ and M _{2 of} 1b and the lengths T _{1 and} T ₂ of the tie portions 20a and 21a being exactly the same. While slightly lengthening the length M ₂ of the portion 21b,
The length T ₂ of the tie portion 21a may be made slightly shorter by that amount, and the cut portions 20b and 21b may have a slight overlap margin in relation to the cut portion 20b of the inner perforation 20.

On the other hand, in the both longitudinal end portions 10 and 10, the inner perforation 20 is formed while the cut portion is dominant, that is, the length of the cut portion 20b is extremely long, and the inner perforation 20 is formed. Tie part 20a
The outer perforation 21 is formed so that the cut portion 21b of the outer perforation 21 is located outside of. When the opening piece 2 is cut off and removed, the end portion 10 in the longitudinal direction becomes the first cleavage point, so that it can be easily cleaved with a small force. In addition, in both longitudinal end portions 10, especially, the outer perforations 21 have only the cut portions scattered,
Although it may depart from the general concept of perforations, in the present invention, in the sense that the tie portion and the cut portion are alternately repeated along a predetermined straight line or curved virtual line even if it is irregular. , Perforated within the concept.

If the distance d between the inner perforation 20 and the outer perforation 21 is too large, the cut piece 2 is simply cut along the inner perforation 20 when the opening piece 2 is cut off and removed. D = 0.5 to 1 mm, and preferably d = 0.5 to 1 mm, so that the opening / closing piece 2 can be reliably and cleanly cut and removed while the line alternates between the cut portions 20b, 21b between the inner perforation 20 and the outer perforation 21. It is good to set it to about 0.6 to 0.8 mm.

Further, fingertip insertion portions 3 necessary for cutting and removing the unsealing piece 2 are formed at both ends in the longitudinal direction of the unsealing piece 2. The fingertip insertion portion 3 is a semi-circular perforation having a pair of 90-degree arc-shaped cut lines 3c and 3c for forming a finger-tip hole and a tie portion 3a in the middle, and a radial line of the semi-circular perforation. The fold line 3b is formed in the part. In removing the opening piece 2, the fingertip is pushed into one of the fingertip insertion portions 3 and 3, and then the fingertip is inserted into the fingertip insertion portion 3 as shown in FIG.
It is pulled up upward while being hooked on, and is torn open along the double perforation C and removed.

By the way, in the present invention, the opening piece 2,
That is, the shape of the outlet is not limited to the above example. For example, the shape may be an appropriate shape such as a rectangular shape or an elliptical shape.

[0016]

As described above in detail, according to the present invention, the surrounding paper is thinly peeled off when the opening piece is cut off according to the perforation forming perforation formed on the upper surface of the tissue paper storage box. Not only that, it can be a tissue paper storage box that has a beautiful cut edge over the entire circumference.
