Description

  The present invention relates to a tissue paper box that is easy to dispose of and can be easily disassembled after use.

  A rectangular parallelepiped or cubic paper box used for storing thin paper such as facial tissue is bulky as it is after use and is discarded in a disassembled form. The dismantling operation is performed in three stages: the operation of opening the upper and lower flaps, the operation of opening the left and right inner flaps, and the operation of flattening the paper box. In one operation, it is fixed with an adhesive such as hot melt. The upper and lower flaps on the side of the paper box are peeled off. In order to make this easier, there are some which have perforations on the side of the paper box. (See Patent Documents 1 and 2).

JP-A-5-32279 JP 2002-29580 A

  However, since the left and right inner flaps close the opening after the upper and lower flaps are cut open at the perforation, it is necessary to open the left and right inner flaps. During the operation of opening and flattening the inner flap, a finger may touch the tip corner of the inner flap and be injured. An object of the present invention is to provide a paper box in which disassembly is further facilitated and safety is improved by omitting an operation of opening the inner flap in the disassembly operation.

(1) Of the four side surfaces connected from the top surface of the paper box having the tissue paper outlet, the two parallel side surfaces of the opening for inserting the tissue paper are a pair connected from the other two side surfaces. The inner flap and a pair of upper and lower outer flaps connected to the top surface or the bottom surface, after inserting the tissue paper, the inner flap is folded inward, then the lower flap and the upper flap are folded in this order, the side opening The part is closed. The top and bottom outer flaps overlap at the tip.
The side surfaces are closed by joining the inner flap and the upper and lower outer flaps with hot melt or vinyl acetate adhesive.
(2) In the present invention, the upper outer flap or the lower outer flap is provided with a disassembling perforation or cut, and further, a disassembling perforation or cut is provided at a predetermined position of the pair of inner flaps, and the inner flap and the upper and lower outer flaps are joined The upper and outer flaps and the lower and outer flaps overlap each other.
(3) Disassembling perforations or notches for upper and lower outer flaps or lower and outer flaps are provided in the lateral direction along the upper edge of the flap on the outer periphery of the portion to which the adhesive is applied or in the vicinity thereof (slightly outside the adhesive applying portion). In the central portion, a portion pinched with an arcuate finger is provided.
(4) The pair of left and right inner flaps are provided with perforations or cuts (A) extending in the lateral direction at positions overlapping the disassembling perforations or cuts provided in the upper and lower or lower outer flaps. A perforation or cut (B) for longitudinally cutting the inner flap is provided in the vicinity of the bent crease line.
(5) Upper and lower outer flaps by making the joint strength of the left and right inner flaps and the upper and lower outer flaps and the lower outer flap higher than the breaking strength of the disassembling perforations or cuts (A) and (B) provided in the inner flaps When disassembling, the perforations or cuts provided in the inner flap are destroyed at the same time, and the broken pieces can be disassembled while being joined to the upper and outer flaps and the lower and outer flaps.
(6) The breaking strength of the disassembling perforations or cuts provided in the inner flap is preferably 50 gf or more and 300 gf or less. If it is less than 50 gf, the perforation or incision strength is too weak and may break due to equipment in the flap joining process. If it exceeds 300 gf, the perforation will not break if there is a variation in joining strength. There is a possibility of disconnection.
(7) The adhesive for joining the left and right inner flaps to the upper and lower outer flaps and the lower outer flap is applied to the inside of the upper and lower outer flaps, but the position is in the vicinity of the disassembling perforation, from 1 mm to 12 mm. It is desirable to apply to the inside (the base side of the flap) of the upper and lower outer flaps, respectively, for the dismantling perforations or cuts. This is because when the upper and lower outer flaps are disassembled, the moment of the peeling force acting on the joint portion of the inner flap is reduced, so that the upper outer flap and the lower outer flap and the inner flap are less likely to be peeled off. This is because the perforation or incision for breaking the inner flap can be broken and separated while the lower and outer flaps are joined.
(8) The bond width of the perforation or the cut portion is 0.2 mm or more and 1.0 mm or less, and the ratio of the bond portion to the total length of the perforation or the cut portion is preferably about 2 to 15%.

When disassembling and disposing of a conventional paper box with dismantling perforations on the upper or lower flaps, break the arc-shaped perforations on the upper or lower outer flaps and remove the upper and lower outer flaps from there. Cut along the perforation to break the joint with the left and right inner flaps, open the left and right inner flaps, flatten, reduce the bulk and discard. That is, three stages of operations are necessary: an operation of opening and closing the upper and lower flaps of the side surface, an operation of opening the inner flap to the left and right, and an operation of flattening. Here, according to the present invention, a predetermined perforation or a cut is provided in the inner flap, and the upper and lower outer flaps are joined at a predetermined position. By adjusting the joining strength and the strength of the inner flap perforation or the cut portion, Since the inner flap is destroyed and removed simultaneously with the flap opening operation, the operation of opening the left and right inner flaps can be omitted. It is also possible to avoid injury by touching the inner flap tip corner with a finger. In addition, the perforations or cuts of the inner flap are hidden inside the upper and lower outer flaps and are not exposed to the outside when the tissue paper box is used. It is not mixed in.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. This is for illustrative purposes and is not intended to limit the invention.

FIG. 1 is a perspective view showing a configuration of a flap of one side opening of a tissue paper box according to an embodiment of the present invention. Dismantling perforations are made on the lower outer flap.
FIG. 2 shows a perspective view when the flap on one side of the tissue paper box of the present invention is closed.

In the conventional tissue paper box, as shown in FIG. 3, the lower outer flap 3 and the upper outer flap 2 are respectively joined to the inner flap 4 with an adhesive. When the paper box is disassembled, the perforation of the lower outer flap is the first stage. The upper outer flap 2, the lower outer flap 3, and the inner flap 4 are peeled off, the left and right inner flaps in the second stage are opened to the outside, and then the third stage paper box is flattened.

In the present invention, assembling of the side surface on the opening side where the tissue paper bundle is inserted is as shown in FIG. 1, the left and right inner flaps 4 are folded oppositely to the opening side, and the lower and outer flaps 3 are folded, Flap 2 is folded. As shown in FIG. 4, the adhesive for joining the flaps is partially applied to the inner part of the upper outer flap 2 and the lower outer flap 3, the part 5 overlapping the inner flap and the part 6 overlapping the upper and lower outer flaps. To do. The disassembling perforation 7 is provided in the lateral direction in the vicinity of the portion overlapping the upper and outer flaps of the upper edge of the lower outer flap (FIG. 6A). This perforation may be a notch. An arc-shaped portion is provided at the center of the disassembling perforation 7, and this portion is first broken at the time of disassembling and pulled up in the direction of the top surface, and the upper and outer flaps are peeled and disassembled. The disassembling perforation 7 may be provided on the upper and outer flaps (FIG. 6B).

In the present invention, as shown in FIG. 7, the inner flap is provided with a perforation or a notch for disassembly. The inner flap perforation or incision consists of a lateral direction (horizontal direction) (A) and a longitudinal direction (substantially vertical direction) (B). The lateral perforation or incision (A) is a perforation for dismantling the lower outer flap. Alternatively, it is provided at substantially the same position as the cut. The vertical perforations or incisions (B) bend in the vicinity of the inner flap bent crease (D) and intersect the lateral perforations or incisions (A) at the intersection (C). The vertical perforations or cuts (B) do not overlap the bent crease lines (D) except at both ends. The vertical perforations or cuts (B) may be straight. Longitudinal perforations or incisions (B) should not overlap with the bent folding lines of the inner flap as much as possible. When the vertical perforation or incision (B) overlaps with the bent folding ruled line of the inner flap, the repulsion to the outside is weakened when the inner flap is bent, and the pressing force at the time of joining the upper and lower flaps to the inner flap is weakened and adhesion is achieved. become weak.

In the present invention, as shown in FIG. 4 as an example, the flap bonding adhesive is applied and bonded in the vicinity of the disassembling perforations or cuts applied to the lower outer flap. As shown in FIG. 5, the adhesive is applied to a position 1 to 12 mm away from the perforation or cut portion 7, preferably (A) is 5 to 12 mm, and (A) is 2 to 5 mm. Although FIG. 4 shows the case where the lower outer flap is provided with the disassembling perforation, even when the upper outer flap has the disassembling perforation or the cut, it is applied and joined at the same position as described above. The smaller the distance from the perforation or cut 7 to the joint, the smaller the joint peeling moment acting on the joint with the inner flap when opening the upper outer flap or lower outer flap from the perforation or cut. When the outer flap and the lower outer flap are peeled off, the disassembling perforations or cuts made on the inner flap without breaking the joint with the inner flap are easily separated.

In the present invention, the disassembling perforations or cuts may be used in combination. The perforation or cut portion 7, (A), (B) is provided with a bond portion (uncut portion), the width is 0.2 mm to 1.0 mm, and the ratio of the disassembled portion to the bond portion is 2 It is desirable that it is ˜15%. The breaking strength of the disassembling perforations or cuts is preferably 50 gf or more and 300 gf or less. If it is less than 50 gf, the strength of the perforation or the notch is too weak, and there is a possibility that it will be broken by equipment in the flap joining process, and if it exceeds 300 gf, there is a possibility that the joining will come off if the joining strength varies.

FIG. 8 shows the disassembled state of the side surface of the tissue paper paper box of the present invention.

FIG. 9 is a measurement diagram of the breaking strength of the perforation or the cut and the bonding strength of the flap joint.
Measured according to JIS-k6854-3.
