Description

In the present invention, when the end of the tissue paper protruding from the upper surface plate of the box is pulled up, the tissue paper can be pulled out, and the end of the next tissue paper protrudes from the upper surface plate and is stored inside the box. The present invention relates to a tissue paper box in which a large number of tissue papers can be withdrawn sequentially and sequentially.

  A conventional typical tissue paper box is a paper cuboid box as shown in FIG. 3, and a cutout portion surrounded by a cut line is provided at the center of the upper surface plate b of the box body a. When the cut portion is cut along the cut line, an opening c is formed. The opening c is closed by a film-like synthetic resin sheet d attached to the back surface of the upper surface plate b, and the synthetic resin sheet. A straight slit e is provided in the center of d in the longitudinal direction of the box body a, and the tissue paper f stored therein can be intermittently and sequentially drawn out through the slit e.

  Generally, after the stored tissue paper is used up, it is incinerated as garbage, or the empty box is crushed to be flat and discarded as resource garbage. The empty boxes collected as resource waste are used as raw materials for recycled paper. However, since the film-like synthetic resin sheet d is attached to the empty box, the synthetic resin sheet d must be peeled off before being discarded as resource waste or after being accumulated as resource waste. For this reason, the operation of peeling the synthetic resin sheet d is troublesome, and there is a problem that the workability at the time of paper recycling is lowered.

In order to solve such a problem, for example, a synthetic resin sheet with a slit is abolished, slits are formed at both ends of the tissue paper outlet, and the both sides of the tissue paper are pulled out to the slit, and as it is pulled out The next tissue paper is also sandwiched between the slits so that the rising state is maintained, and bending slits are provided in a substantially C shape on both sides of the slit. Patent Document 1 describes a tissue paper box that facilitates the withdrawal of tissue paper.
Japanese Patent Laid-Open No. 9-30573

  According to the tissue paper box in which the synthetic resin sheet as described above is abolished, it is possible to save the trouble of peeling the synthetic resin sheet when used as a raw material for recycled paper after use. However, when using as a tissue paper box, the both ends of the tissue paper are only supported by being sandwiched between the slits formed at both ends of the outlet, so that when pulling out the tissue paper There is a problem that it is easily detached from the slit. If the tissue paper is removed from one of the slits, the drawer operation cannot be performed smoothly, and the tissue paper may be twisted or torn. Problems such as being stable or falling off the slits on both sides and falling into the box are likely to occur. In addition, since the outlet is exposed on the top plate, there is a problem that even if the size of the outlet is set to the minimum necessary, dust or the like can enter the box and contaminate the stored tissue paper. It was.

  The present invention has been made to solve the problems of the conventional tissue paper box, and is a tissue paper box in which the synthetic resin sheet is abolished, and the tissue paper is twisted or torn. It is an object of the present invention to provide a tissue paper box that can be smoothly drawn out, can stably maintain the subsequent rising state of tissue paper, and can suppress entry of dust and the like.

As means for achieving the above object, claim 1 of the present invention is that a large number of tissue papers are stored in a stacked state inside a box body formed in a rectangular parallelepiped or a cube, and each tissue paper has an end portion between each other. A tissue paper box that is engaged by folding and is configured to intermittently and sequentially pull out the tissue paper from a take-out slit provided on the top plate of the box body,
A first flap and a second flap are formed adjacent to each other on the upper surface plate of the box body;
Both the first flap and the second flap are elastically connected to the upper surface plate at the base end side edge,
A non-linear slit is formed by opening an adjacent opposite side edge portion through a cut line,
The first flap has a base end side edge portion formed in a straight line parallel to the side edge of the upper surface plate, and an opposite side edge portion formed in a substantially convex arc shape by a cut line. Are respectively connected to the ends of the base side edges,
The second flap is formed in a linear shape with the base end side edge parallel to the side edge of the top plate, and the opposing side edge is a substantially convex arcuate opposing side edge in the first flap. And a straight line portion located on both ends of the curved portion is formed by a cut line, and an end portion of the straight line portion is connected to an end portion of the base side edge portion. And the round part is provided in the connection location of a curved part and a straight part, It is characterized by the above-mentioned.

Claim 2 of the present invention, the tissue paper for box according to claim 1, the length A proximal edge of the first flap to the side edge length G of the top plate 0 .9G>A> 0.5G, and the height E from the base side edge to the top of the substantially convex arcuate opposing side edge is 0 with respect to the edge length H of the top plate. 8H>E> 0.2H, and the length D of the base end side edge portion of the second flap is 0.9G>D> 0.5G with respect to the side edge length G of the top plate. The height F of the substantially concave arc-shaped opposite side edge from the base side edge to the rounded part is 0.8H>F> 0.2H with respect to the edge length H of the top plate. It is characterized by being.

According to a third aspect of the present invention, in the tissue paper box according to the first or second aspect , a finger is placed at a substantially central portion of a region where the first flap and the second flap are adjacent in an arc shape. A substantially semicircular opening for hooking is connected to the first flap side and provided through a cut line.

  According to the first aspect of the present invention, since the extraction slit in the tissue paper box is a non-linear slit, the rising state of the tissue paper can be stably maintained as compared with the linear slit. . Thereby, the synthetic resin sheet used conventionally becomes unnecessary, and the time which peels off a synthetic resin sheet when using as a raw material for recycled paper after use can be saved. In addition, the process can be reduced when the box is manufactured, and the cost can be reduced. Furthermore, since the non-linear slit is closed by the tissue paper maintained in the rising state, it is possible to prevent dust and the like from entering the box.

According to the first aspect of the present invention, since the base end side edges of the first flap and the second flap are both formed in a straight line parallel to the side edge of the top plate, a relatively long dimension is provided. By securing, the elastic force between the first flap and the second flap can be improved. Moreover, since the opposing side edge part of a 1st flap and a 2nd flap is formed by tying together in a substantially uneven | corrugated arc shape by a cut line, when a cut line is opened, a substantially arc-shaped curve part and this curve It is possible to easily form a non-linear slit composed of straight portions positioned on both ends of the portion. Furthermore, since the rounded portion is provided at the connection portion between the curved portion and the straight portion, the resistance at the connection portion between the curved portion and the straight portion can be weakened when pulling out the tissue paper. Will not be twisted or torn.

According to the second aspect of the present invention, by setting the sizes of the first flap and the second flap to the sizes of the appropriate ranges as described above, a non-linear slit of a preferable form is formed, In addition, an appropriate elastic force can be applied to each flap. As a result, the tissue paper can be easily pulled out, the rising state of the subsequent tissue paper can be reliably maintained, and the intrusion of dust or the like can be suppressed.

According to the third aspect of the present invention, the first semi-circular opening for hooking a finger is provided in the first central portion of the region where the first flap and the second flap are adjacent to the concave and convex arc shape. Since it is provided via a cut line connected to the flap side, a non-linear slit can be easily formed by first opening the opening when opening and then opening along the cut line.

  Next, an embodiment of a tissue paper box according to the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view showing an embodiment of a tissue paper box according to the present invention. FIG. 2 is a perspective view showing a use state of the tissue paper box according to the present invention.

  In FIG. 1, reference numeral 1 denotes a box body formed in a rectangular parallelepiped (in some cases a cube) with relatively thick paper, and is cut by a known method to form an original pattern by providing stamped lines and cut lines at predetermined locations. Then, the original pattern is mechanically folded and glued at a required location for factory production. The description of the production process of the box body 1 is omitted. In addition, 200 sets of tissue papers are usually stored in a stacked state in the box body 1, and one set of tissue papers is a two-layered one, and the ends of each set are folded and engaged with each other. By doing so, the pop-up type can be pulled out intermittently.

  A first flap 2 and a second flap 3 are formed adjacent to and opposed to the upper surface plate 1 a of the box body 1. The first flap 2 has a base end side edge 2a formed in a straight line parallel to one side edge of the upper surface plate 1a as viewed from above, and an opposed side edge 2b formed in a substantially convex arc shape. The base side edge 2a is stamped when forming the original pattern, and the opposite side edge 2b is cut.

  The second flap 3 has a base end side edge portion 3a formed in a straight line parallel to the other side edge of the upper surface plate 1a as viewed from above, and an opposing side edge portion 3b substantially the same as that of the first flap 2. A substantially concave arcuate curved portion 3b (A) along the convex arcuate opposing side edge 2b, and a predetermined length from both ends of the curved portion 3b (A) to the corner of the upper surface plate 1a. The base end side edge 3a is stamped when forming the original pattern, and the opposite side edge 3b is cut. Yes. In this case, the cut line of the curved portion 3b (A) in the second flap 3 is common to the cut line of the opposing side end portion 2b in the first flap 2 in the tying state. In addition, rounded portions 3c are provided at connection points between the curved portion 3b (A) of the second flap 3 and the linear portions 3b (B) located on both sides thereof.

  Reference numeral 4 denotes a substantially semicircular opening for hooking a finger, and the first flap 2 and the second flap 3 are provided at a substantially central portion of an arc-shaped adjacent region via a cut line. ing. In this case, the base end side edge 4a of the opening 4 is not provided with a cut line, but is formed with a push rule and connected to the first flap 2 side. Therefore, the cut line of the opposite side edge 3a in the second flap 3 is blocked by the base end side edge 4a of the opening 4 but through the substantially semicircular cut line in the opening 4 The whole will be continuous.

  The embodiment of the tissue paper box according to the present invention is configured as described above, and in order to open the box body 1, a finger is placed on the opening 4 to cut a substantially semicircular cut line, and this cut line The cut line provided in the opposing side edge 2b of the first flap 2 following the slit is cut open, and provided in the rounded portion 3c of the opposing side edge 3b and the straight portions 3b (B) on both sides of the second flap 3. Cut the cut line. The curved portion 3b (A) of the second flap 3 is cut open simultaneously with the opening of the opposing side edge portion 2b of the first flap 2.

  After opening the box body 1, the first flap 2 is slightly opened, fingers are inserted, and when the edge of the top tissue paper stored in the box body 1 is picked up, the edge of the tissue paper is The second flap 3 can be raised along the opposing side edge 3b. By using this standing state, the tissue paper can be used. That is, as shown in FIG. 2, in the upper surface plate 1 a of the box body 1, a non-linear slit S is formed by the curved portion 3 b (A) and the straight portion 3 b (B) of the second flap 3.

  When the tissue paper box is used, a pair of tissue papers P can be pulled out by grasping an end of the tissue paper P protruding in a rising state from the slit S and pulling it up straight. At this time, along with the upward movement of the tissue paper P, the first flap 2 opens with the proximal end side edge 2a provided with the stamped rule as a support portion, and at the same time, the second flap 3 also provides the stamped rule. The base end side edge portion 3a is opened as a support portion. Thereby, the pulling-out resistance of the tissue paper P can be weakened, and the tissue paper P can be pulled out lightly. Further, the tissue paper P is pulled out while being sandwiched between the slits S, but the opening 4 is substantially semicircular and is connected to the curved portion 3B (A) and the straight portion 3b (B) of the second flap 3. Since the rounded portions 3c are respectively provided at the locations, the tissue paper P is not twisted or torn by contact with the tissue paper P.

  When the tissue paper P is completely pulled out, the pull-out resistance is lost, and the first flap 2 closes elastically with the proximal edge 2a provided with the crease provided as a support, and at the same time, the second flap 3 Also, the base end side edge portion 3a provided with the push ruler is closed by elasticity with the support portion. As a result, the protruding end portion of the tissue paper following the drawn tissue paper P is sandwiched in the slit S and stopped to be in a rising state. At this time, as shown in FIG. 2, the protruding end of the tissue paper stands up in a bent state along the non-linear slit S, and a total of 3 of the opening 4 and the rounded portions 3c located on both sides thereof. Since the pressure is applied at the location, the rising state of the tissue paper can be maintained stably. The direction in which the opening 4 pushes the tissue paper and the direction in which the rounded portions 3c located on both sides push the tissue paper are in opposite directions in the plane, so the balance of force is almost balanced.

  In the standing state of the tissue paper, the slit S is closed by sandwiching the tissue paper, and the opening 4 is pushed between the second flap 3 by pushing the tissue paper, and the second flap 3 from which the opening 4 is removed. The side vacant area is blocked. Further, since the first flap 2 is also closed, there is almost no gap between the skirts of the opposite side edge 2b and the upper surface plate 1a. In addition, there is almost no gap between both skirts of the straight line portion 3b (B) and the upper surface plate 1a in the second flap 3. Thereby, since there is almost no gap in the upper surface plate 1a, it is possible to prevent dust and the like from entering the box body 1 in the rising state of the tissue paper.

  The tissue paper is pulled out intermittently, and each time the first flap 2 and the second flap 3 are repeatedly opened and closed by an elastic action using the base end side edges 2a and 3a provided with the stamped rule as support portions. . By repeating such an opening and closing operation, the elastic action of the first flap 2 and the second flap 3 is gradually deteriorated, resulting in settling. When settling occurs, the holding force to keep the protruding end of the tissue paper following the pulled out tissue paper in a standing state may drop and fall into the box body 1, and if this happens, it will hinder continued use. Will come. It is desirable that the elastic force of the first flap 2 and the second flap 3 is maintained until all the tissue paper stored in the box body 1 is used up.

  The elastic forces of the first flap 2 and the second flap 3 are mainly related to their sizes, so that the width of the tissue paper P drawn from the slit S is taken into consideration and the first flap 2 and the second flap 3 Change the size of the flap 3 of the test in several ways, test whether the stored tissue paper is used up to the end without dropping, and also check whether the tissue paper is torn when pulled out Observed.

  In the above test, as shown in FIG. 1, the length of the base end side edge 2a of the first flap 2 is A, and the base end side edge 2a of the substantially convex arcuate opposing side edge 2b is extended from the top. And the length of the base side edge 3a in the second flap 3 is D, and the length from the base side edge 3a of the substantially concave arcuate side edge 3b to the rounded part 3c. The height was F. And the length of the side edge in the upper surface board 1a of the box main body 1 was set to G, and the length of the edge was set to H.

  Samples of Examples 1 to 9 were manufactured by changing the sizes of A, E, D, and F, and a pull-out test was performed using a representative product shown in FIG. 3 as a comparative example. The test results are shown in Table 1 below.

  According to the test results in Table 1, all of Examples 1, 2, 4, 4, 5, 7, and 8 can pull out the tissue paper to the end, and tearing occurs at the time of pulling out. There wasn't. In each of Example 3, Example 6, and Example 9, the tissue paper dropped halfway and could not be pulled out to the end, and there was a case where tearing occurred at the time of pulling out. In the comparative example, the tissue paper could be pulled out to the end, and no tearing occurred at the time of pulling out.

  From this test result, the first flap 2 is good if A is in the range of 0.6G ≦ A ≦ 0.8G and E is 0.3H ≦ E ≦ 0.6H, and E is 0. .8H or more is impossible. That is, it has been found that it is not good if the height E of the substantially convex arcuate opposing side edge 2b is too high. The second flap 3 facing the first flap 2 is also good if D is in the range of 0.6G ≦ D ≦ 0.8G and F is 0.3H ≦ F ≦ 0.6H. It becomes impossible when it is 0.8H or more. As a result, if the curve portion 3b (A) of the slit S is too curved, the pull-out resistance of the tissue paper P is increased, and the first flap 2 and the second flap 3 are prematurely crushed. It is thought that the tissue paper will be easily broken.

  From the above, it is preferable that A is 0.9G> A> 0.5G and E is in the range of 0.8H> E> 0.2H. Correspondingly, it was found that D is also 0.9G> D> 0.5G, and F is preferably in the range of 0.8H> F> 0.2H.

  The present invention can be suitably used for a tissue paper box. Since the synthetic resin sheet is not used, the tissue paper box according to the present invention is suitable for the paper recycling industry to be used as used paper after use.

It is a top view which shows embodiment of the box for tissue paper which concerns on this invention. It is a perspective view which shows the use condition of the box for tissue paper which concerns on this invention. It is a perspective view which shows the conventional box for typical tissue paper.
