The second flap cut lines 28, 28 extend from the edge portions on both sides of the opposing longitudinal direction lines of the contour cut line 21 toward both longitudinal ends of the upper panel 7 and reach both longitudinal ends of the upper panel 7. There is no length in the range. The length of the second flap cut lines 28, 28 is not particularly limited. However, if the length is short, the significance of the presence of the second flap portions 27, 27 for expansion is weakened. If the length is too long, the strength of the top panel 7 is weakened. Accordingly, the length is set so as to fulfill the significance of the presence of the second extension flap portions 27, 27 and the strength of the top panel 7 is not significantly reduced. In the reference example, the length of the second flap cut lines 28, 28 is the length between the longitudinal end portion of the take-out port 20 formed by the contour cut line 21 and the longitudinal end portion of the top panel 7. The length is approximately 1/2 to 1/4.

In the reference example, the two opposing second flap cut lines 28, 28 are formed in a shape in which the respective tip portions 28a, 28a are bent so that the corners 29, 29 are arcuate in the opposing direction. Has been. Further, the width of the second flap portions 27 and 27 for expansion formed by the second flap cut lines 28 and 28 is the same as the width of the second opening portions 24 and 25 of the take-out port 20 formed by the contour cut line 21. Any of width, narrow width, and wide width may be used. When the width of the second extension flap portions 27, 27 is narrower or wider than the width of the second opening portions 24, 25, the connecting portion between the second flap cut lines 28, 28 and the contour cut line 21 Are connected in a curved or straight line. By doing so, when the sanitary paper 2 is taken out from the take-out port 20, it can be drawn out with a small frictional resistance.
In the reference example, the width of the second flap portions 27 and 27 for expansion formed by the second flap cut lines 28 and 28 is the width of the second opening portions 24 and 25 of the take-out port 20 formed by the contour cut lines 21. It is wider.
In the reference example, the upper panel 7 is opposed to the second flap portions 27 and 27 for expansion that extend the extraction port 20 at both ends in the longitudinal direction of the extraction port 20 formed by the contour cut line 21. However, the present invention is not limited to this, and the second flap portion 27 for expansion is provided only at one end in the longitudinal direction of the outlet 20. Two opposing second flap cut lines 28 for forming may be provided.

Each of the first flap portions 22 and 22 and each of the second expansion flap portions 27 and 27 is provided with an easy curve portion 30 that imparts elasticity and flexibility. The easy-curve portion 30 is provided at the root portion of each of the first flap portions 22 and 22 and each of the second expansion flap portions 27 and 27.

In the reference example, one to a plurality of easy curve portions 30 are provided in each of the first flap portions 22 and 22 and the second expansion flap portions 27 and 27.
In the reference example, each of the first flap portions 22 and 22 and each of the expansion second flap portions 27 and 27 are provided with easy-curve portions 30 that impart elasticity and flexibility. However, the present invention is not limited to this. The easy curve part 30 may be provided in any one of each 1st flap part 22 and 22 and each 2nd expansion flap part 27 and 27 instead of a thing. The easy curve portion 30 is preferably a ruled line, but a weakening method such as perforation may be used. A ruled line intended to be easily bent due to weakening uses an effect of being easily bent along the ruled line due to a decrease in strength at the boundary of the ruled line. In the reference example, the easy curve portion 30 is a ruled line.

Further, the upper panel 7 is positioned around and intersects the take-out port 20 formed by the contour cut line 21 and the expansion second flap portions 27 and 27 formed by the second flap cut lines 28 and 28. Ribs 32 including the ruled line portions 31 are provided in a plurality of locations. In the reference example, the take-out port 20 and the expansion second flap portions 27, 27 are sandwiched between the take-out port 20 and the expansion second flap portions 27, 27 on diagonal lines in the longitudinal direction and the short direction. The rib 32 is formed by crossing the ruled line portions 31 formed in an arcuate shape back to back. The ruled line portion 31 to be the rib 32 uses the compression of the ruled line portion and the bending strength due to the linear three-dimensional structure.

  The box body 1 having such an unfolded structure is formed by folding the back panel 6, the top panel 7, the front panel 8, the bottom panel 9, and the glue allowance panel 19 from the fold lines 3, 4, 5, 18. The panel 19 is bonded to the back panel 6, and the folding panels 16 and 17 connected to the left and right edges of the back panel 6 and the front panel 8 are folded from the folding lines 14 and 15, and the top panel 7 and the bottom panel 9 The side panels 12 and 13 connected to the left and right edges are folded from the folding lines 10 and 11 and overlapped on the outside of the folding panels 16 and 17, and the side panels 12 and 13 are bonded.

  In this box 1, before the side panels 12 and 13 are bonded, the sanitary paper 2 that is alternately folded and stacked so as to be taken out in a pop-up manner is stored, and the side panels 12 and 13 are bonded and sanitized. The paper storage box is completed (FIG. 1).

In opening the sanitary paper storage box thus completed, the finger hole cut line 26 provided in the second opening portion 24 of the take-out port 20 formed by the contour cut line 21 is pushed and opened, The finger is inserted and pulled up, the contour cut line 21 is cut , the portion surrounded by the contour cut line 21 is cut , and the take- out port 20 is opened (FIG. 4).

The sanitary paper 2 located at the uppermost portion stored in the box 1 is taken out from the take-out port 20 thus opened. At this time, in the reference example, one second opening portion 24 of the second opening portions 24 and 25 formed on both sides of the first opening portion 23 in the take-out port 20 is a wide surface. If it takes out from the 2nd opening part 24 of this, a finger will be easy to put in the taking-out opening 20, and the sanitary paper 2 can be picked easily.

  When the sanitary paper 2 is taken out from the take-out port 20, the first flap portions 22, 22 protruding in the direction approaching the long sides 20 a, 20 a of the take-out port 20 in the process of taking out the sanitary paper 2 are pushed up. The first opening portion 23 having a narrow width between the first flap portions 22 and 22 is widened, and the second expansion slit formed by second flap cut lines 28 and 28 provided at both ends in the longitudinal direction of the take-out port 20. The flaps 27 and 27 are pushed up, and the take-out port 20 expands in the longitudinal direction by pushing up the second extension flaps 27 and 27. Accordingly, the frictional resistance between the take-out port 20 and the sanitary paper 2 is reduced accordingly. Thus, the sanitary paper 2 can be easily taken out from the take-out port 20.

In particular, in the reference example, the second flap cut lines 28 and 28 are formed in a shape in which the respective distal end portions 28a and 28a are bent so that the corner portions 29 and 29 are arcuate in the opposing direction. When the paper 2 is taken out, the sanitary paper 2 is pulled out to one side of the longitudinal end of the take-out port 20, and the sanitary paper 2 pushes up one of the expansion second flaps 27 so that the sanitary paper 2 is expanded. The sanitary paper 2 can be received by the corner portion 29 formed in an arc shape even when the second flap cut line 28 that forms the root portion of the second flap portion 27 is near the tip end portion 28a side. Therefore, the frictional resistance between the end of the take-out port 20 in the longitudinal direction and the sanitary paper 2 drawn out is small, and the sanitary paper 2 can be smoothly taken out from the take-out port 20.

In the reference example, the second extension flaps 27 and 27 are wider than the widths of the second opening portions 24 and 25 of the take-out port 20. By pushing up the second flap portions 27, 27, the take-out port 20 is greatly expanded and opened, and the frictional resistance between the take-out port 20 and the sanitary paper 2 can be further reduced. 2 can be taken out more easily.

In the reference example, the first flap portions 22 and 22 and the expansion second flap portions 27 and 27 are provided on the root portion, the first flap portions 22 and 22 and the expansion second flap portions 27 and 27. Since each of the first flap portions 22 and 22 and each of the expansion second flap portions 27 and 27 are provided with easy-curve portions 30 that impart elasticity and flexibility, the sanitary paper 2 is removed in the process of being taken out. The first flaps 22 and 22 and the expansion second flaps 27 and 27 that have been pressed in the take-out direction by the paper 2 are bent with a light press due to the presence of the easy-curve 30 and are easily pushed up. The frictional resistance between the mouth 20 and the sanitary paper 2 can be further reduced, and the sanitary paper 2 can be taken out from the take-out port 20 more easily.

  In addition, after the sanitary paper 2 is taken out, the first flap portions 22 and 22 and the second extension flap portions 27 and 27 released from the press by the sanitary paper 2 have the take-out port 20 narrowed by a restoring force. The next sanitary paper 2 drawn out after the sanitary paper 2 is taken out by the narrow first opening portion 23 formed between the restored first flap portions 22 and 22 can be While being able to hold | maintain reliably, the approach of dust etc. in the box 1 can be decreased as much as possible by each returned 2nd expansion flap parts 27 and 27 for expansion.

In the reference example, the top panel 7 is positioned around the take-out port 20 formed by the contour cut line 21 and the second flap portions 27 and 27 for expansion formed by the second flap cut lines 28 and 28. The rib 32 composed of the crossed ruled line portions 31 sandwiches the take-out port 20 and the second extension flap portions 27 and 27 in the longitudinal direction and the short direction of the take-out port 20 and the second extension flap portions 27 and 27. Since it is provided on a diagonal line, it is possible to reinforce the periphery of the take-out port 20 and the expansion second flap portions 27 and 27 in the upper surface panel 7 of the box body 1, and is surrounded by the contour cut line 21 from the upper surface panel 7. When the sanitary paper 2 is taken out from the take-out opening 20 and when the box body 1 is manufactured, the area around the take-out opening 20 of the upper panel 7 and the expansion second flap portions 27 and 27 is cut. It is possible to reduce the damage caused by the applied load. Further, the presence of the rib 32 can enhance the design of the box 1.

Particularly in the reference example, the intersecting ruled line portion 31 that becomes the rib 32 intersects the ruled line portion 31 formed in an arcuate shape in a back-to-back manner, so that the outlet 20 of the top panel 7 and the second extension flap The ribs 32 can forcibly disperse loads from all directions around the portions 27, 27, and the take-out port 20 and the expansion second flap portions 27, 27 in the upper surface panel 7 of the box 1 can be dispersed. The reinforcement around can be further improved.

6 and 7 show a first example of the embodiment of the sanitary paper storage box according to the present invention, FIG. 6 is an enlarged plan view of this example, and FIG. 7 is an explanatory view showing a use state of this example. is there.
This example is for also the reference example and the basic structure, the same portions as in Reference Example omitted denoted by the same reference numerals.

The sanitary paper storage box of this example has a pair of first flap portions 22, 22 on both long sides 20 a, 20 a of the take-out port 20 formed by a contour cut line 21 provided on the top panel 7 of the box 1. An arc-shaped cut line 34 is provided that forms an arc-shaped piece 33 having a convex shape from the root portion of each of the first flap portions 22, 22 toward the tip end side. The arc-shaped piece 33 having a convex shape formed by the arc-shaped cut line 34 has a substantially arc shape in this example, but may have a substantially quadrangular shape with R at the corner.

Other configurations are the same as those of the reference example described above. However, in this example, two opposing second flaps for forming an expansion second flap portion 27 for expanding the extraction port 20 at one end in the longitudinal direction of the extraction port 20 formed by the contour cut line 21. A score line 28 is provided.

According to the sanitary paper storage box of this example configured as described above, the first flap portions 22, 22 that are pressed in the take-out direction by the sanitary paper 2 in the process of taking out the sanitary paper 2 are arcuate cut lines 34. (See FIG. 7; sanitary paper is not shown), but the arc-shaped piece 33 is left, so the surface receiving the pushing force becomes small, and the surface is easily pushed up by bending with a light press. As a result, the frictional resistance between the take-out port 20 and the sanitary paper 2 can be further reduced. This makes it possible to narrow the between the first flap portion 22, 22 facing each other, between the ends of opposing flap portions 22, 22, i.e. more reliably hygienic paper 2 and popup in the first opening portion 23 It can be held in.

  In addition, when the sanitary paper 2 is taken out, the first flap portions 22 and 22 are easily pushed up by taking out the sanitary paper 2, so that it is possible to reduce friction noise when taking out the sanitary paper 2.

  Moreover, after taking out the sanitary paper 2, each 1st flap part 22 and 22 released from the press by this sanitary paper 2 can return easily to the state which narrowed the taking-out port 20 with the restoring force, and each returned The next sanitary paper 2 drawn out after the sanitary paper 2 is taken out can be reliably held by the narrow first opening portion 23 formed between the first flap portions 22 and 22.

8 and 9 show a second example of the embodiment of the sanitary paper storage box according to the present invention, FIG. 8 is an enlarged plan view of this example, and FIG. 9 is an explanatory view showing a use state of this example. is there.
This example is for also the reference example and the basic structure, the same portions as in Reference Example omitted denoted by the same reference numerals.

The sanitary paper storage box of this example is formed by opposing the second flap portions 27 and 27 for expansion at both ends in the longitudinal direction of the take-out port 20 formed by the contour cut line 21 provided on the upper panel 7 of the box body 1. Two second flap cut lines 28, 28 are provided, and each of the second expansion flaps 27, 27 extends from the root portion of each of the second expansion flaps 27, 27 toward the distal end. An arc-shaped cut line 34 that forms an arc-shaped piece 33 having a convex shape is provided. The arc-shaped piece 33 having a convex shape formed by the arc-shaped cut line 34 has a substantially quadrangular shape with corners as R in this example, but may have a substantially arc shape. Other configurations are the same as those of the reference example described above.
According to the sanitary paper storage box of this example configured as described above, the second flap portions 27 and 27 for expansion that have been pressed in the removing direction by the sanitary paper 2 in the process of taking out the sanitary paper 2 are arc-shaped cuts. Although the arc-shaped piece 33 formed by the wire 34 is left to be pushed up (see FIG. 9; sanitary paper is not shown), the arc-shaped piece 33 is left, so that the surface receiving the pushing force becomes small, and it is easily bent and curved with a light pressure. As a result, the frictional resistance between the take-out port 20 and the sanitary paper 2 can be further reduced.

  In addition, when the sanitary paper 2 is taken out, the second flap portions 27 and 27 for expansion can be easily pushed up by taking out the sanitary paper 2, and the friction noise when the sanitary paper 2 is taken out can be reduced.

  In this example, two opposing second flap cut lines 28, 28 that form the second flap portions 27, 27 for expansion are provided at both ends in the longitudinal direction of the take-out port 20. However, the present invention is not limited to this. The two second flap cut lines 28 facing each other for forming the expansion second flap portion 27 are provided only at one end in the longitudinal direction of the take-out port 20. Also good.
