Description

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 tissue paper storage box having a bent piece that can be cut and raised at the bottom.

[0002]

2. Description of the Related Art Generally, a tissue paper storage box stores tissue papers that are stacked in a folded state and can be continuously taken out one by one at the time of use. When the remaining amount of tissue paper becomes low, the tissue paper may not come out continuously from the outlet. Therefore, a bendable piece that can be cut and raised is formed on the bottom of the tissue paper storage box, and when the remaining amount of tissue paper is low, the bendable piece is cut and raised toward the inside of the storage box to lift the tissue paper. The tissue paper storage box that is used is widely used.

However, in the tissue paper storage box of this type, after the bent piece is cut and raised, the bent and bent piece may be collapsed under the influence of the weight of the remaining tissue paper. It was In order to prevent such collapse, for example, in Japanese Utility Model Publication No. 2-42621, the shape of the refraction piece is carefully devised so that two refraction pieces are formed so that these refraction pieces support each other. A tissue paper storage box is disclosed.

As shown in FIG. 8, the bending piece formed on the bottom of the tissue paper storage box has folding lines 50A and 50B which are parallel to each other, and outer ends 51A and 51B of the folding lines 50A and 50B. Of the crease lines 50B and 50A, which are adjacent to each other by the outer perforation lines 53A and 53B that connect the inner ends 52B and 52A of the crease lines 50B and 50A, and the central tear line 54 that connects the fold line inner ends 52A and 52B. Has been formed. The central tearing perforation 54 extends from the fold line inner ends 52A and 52B toward the opposite refraction piece, and has a point symmetric fixed point 55 and fold lines 50A and 50B.
Arc-shaped portions 57A and 57B which are connected to two base points 56A and 56B, which are intersections with a virtual perpendicular line L ′ passing through the inner ends 52A and 52B of B, to form overhang portions 61A and 61B, respectively.
And the base points 56A and 56B are connected in a wavy manner in one cycle, and the overhanging portion 62 extends in the same overhanging direction as the overhanging portions 61A and 61B.
It is constituted by an inverted S-shaped or S-shaped portion 58 forming A and 62B. And the refraction pieces 60A, 60B
After cutting and raising, both refraction pieces 6 at the base points 56A and 56B.
0A and 60B are mutually locked and supported.

[0005]

However, in the tissue paper storage box disclosed in the above publication, the bending piece formed at the bottom has a virtual line connecting the inner ends of the fold line to both fold lines. Since it is vertical, at the time of use, the birefringent pieces merely support each other only in the vertical direction at the locking point.

For this reason, the locking force of the two refracting pieces is not so large, and it is conceivable that the two bending pieces will collapse under the influence of the weight of the remaining tissue paper. In particular, since no force relation acts in the direction along the crease line,
If a force is applied to the outside of both bending pieces, for example, if the bottom surface of the tissue paper storage box faces vertically upward and bends along the fold direction, the locked bending pieces will be It was something that went off.

Therefore, an object of the present invention is to provide a tissue paper storage box in which a pair of refracting pieces that can be cut and raised are formed on the bottom so that the tissue paper can be easily taken out even when the remaining amount of the tissue paper becomes small. In order to provide a tissue paper storage box in which the locking force of both the refraction pieces held in a locked state at the time of cutting and raising is large and the locking relationship between the both refraction pieces does not easily collapse.

[0008]

In order to solve the above-mentioned problems, the present invention is directed to a common dehiscence perforation,
Two unseparable perforation lines that are continuous with this, leaving two fold lines that are parallel to each other and formed at the base end and that can be cleaved and cut and raised in opposition to each other. In a storage box in which a bending piece is formed at the bottom of the box, at the common perforation perforation, a locking portion that bites into each bending piece side is formed, and when both the bending pieces are raised in these locking portions. It is characterized in that they are configured to be locked to each other, and an intersecting angle between a line connecting the innermost parts of the respective locking portions and the standing fold line is an obtuse angle.

[0009]

In the tissue paper storage box according to the present invention, the intersection angle between the line connecting the locking points forming a substantial locking relationship and the standing fold line is an obtuse angle. For this reason,
When the bent pieces are cut and used, the bent pieces that are locked to each other are pressed against each other along the fold direction. Therefore, even if a force is applied to the outside along the fold direction, for example, even if the bottom of the tissue paper storage box bends vertically upward, the locking relationship between the refraction pieces is unlikely to collapse. .

[0010]

EXAMPLES The present invention will be specifically described below with reference to examples. FIG. 1 is a bottom view of a tissue paper storage box according to the present invention. On the bottom surface 20 of the tissue paper storage box 10, outer perforations 30A, 30B, a central perforation 31, and two standing folds 32A parallel to each other,
Refractive pieces 40A and 40B that can be cut and raised by 32B are formed. The position where the refraction pieces 40A and 40B are formed is preferably at the center of the tissue paper storage box bottom 20 and at a position facing the tissue paper outlet 11 provided at the top of the storage box (see FIG. 4).

FIG. 2 is an enlarged view of the refraction pieces 40A and 40B.
Shown in. The outer perforations 30A and 30B are formed by connecting the outer ends 33A and 33B of the fold lines 32A and 32B and the inner ends 33D and 33C of the other fold lines 32B and 32A, respectively.

The central perforation 31 has a fold line inner end 33.
Refraction pieces 40A and 40B originating from D and 33C, respectively.
To form the upper locking pieces 41A and 41B projecting in the direction of the opposite refracting piece, respectively.
The upper protrusions 31A, 31B extending up to 4B and the lower locking pieces 42A, 42B protruding in the same direction as the upper protrusions 31A, 31B are formed on the bending pieces 40A, 40B, respectively. It is constituted by a lower protrusion 31C (corresponding to an S-shape, an inverted S-shape) that connects the points 34A and 34B and the symmetry point 35. Also, the upper locking piece 4
1, the lower locking piece 42 constitutes a locking portion,
When the bending pieces 40A, 40B are erected, the locking portions bite into the bending pieces 40B, 40A of the other party. Locking point 34
Corresponds to the deepest part of the locking part.

The central perforation 31 has a point-symmetrical shape with the symmetry point 35 as a symmetry point because it is locked when it is cut and raised and used. And the locking points 34A, 3
An angle θ formed by an imaginary line L connecting 4B and the fold lines 32A and 32B is set to 95 °.

Refraction pieces 40A, 4 used by cutting and raising
As shown in FIGS. 3 and 4, 0B is contacted and locked at the locking points 34, but since the imaginary line L has an inclination, the bent pieces 40A, 40B is slightly bent in the direction opposite to the direction indicated by the arrow.
Restoring force is generated in the bent bending pieces 40A and 40B,
The restoring force urges the upper locking pieces 41A and 41B in the directions indicated by the arrows, and the bending pieces 40A and 40B are firmly locked at the locking points 34. Therefore, for example, even when the bottom surface 20 is bent toward the inner surface of the tissue paper storage box 10, the bent and bent pieces 40 are cut and raised.
The locking relationship between A and 40B almost never collapses.

Further, as shown in FIG. 5, the bending pieces 40A, 40B in the tissue paper storage box 10 of this type.
Is usually torn by a thumb or the like. At this time, if the fold lines 32A and 32B are parallel to the body portions 21A and 21B of the bottom surface 20, the bending of the bending pieces 40A and 40B becomes easy. .

The present invention is not limited to the embodiment shown here, and the engaging portions are formed on both the refraction pieces, and the line connecting the innermost portions of the engaging portions and the standing fold line. The crossing angle may be an obtuse angle. Therefore, for example, as shown in FIG. 6, the center line may be on the same straight line except for the cut portion. Also, as shown in FIG.
It is also possible to adopt an aspect in which each fold line is not connected to the dehiscence perforation.

If the angle θ formed by the imaginary line L connecting the locking points 34A and 34B and the fold lines 32A and 32B is too large, the S-shaped portion and the inverted S-shaped portion are caught and the distortion becomes large. It becomes difficult to press and mold with fingers. In view of this point, as a result of experiments performed by the present inventors, the angle θ
Is affected by the size and material of the refracting piece,
It has been found that it is desirable to set in the range of 120 °, and the most preferable angle within that range is 95 °.

[0018]

As is apparent from the above description, according to the present invention, the locking force of the two refraction pieces that are in the locked state at the time of cutting and raising is increased, and thus the locking relationship between the both refraction pieces is increased. It is possible to provide a tissue paper storage box that does not easily collapse.
