Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to tissue storage boxes. [Background technology]

[0002] In recent years, growing consumer awareness of hygiene has led to an increase in demand for disposable sanitary tissue paper and wipers. This trend in increasing demand is evident not only among medical institutions and nursing care facilities, but also among general consumers. This has led to a demand for more hygienic storage boxes for sanitary tissue paper and wipers (tissue paper storage boxes). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-18010 [Patent Document 2] Patent No. 4095841 [Patent Document 3] Special Publication No. 55-46949 Summary of the Invention [Problem to be solved by the invention]

[0004] Paper cartons are often used as tissue paper storage boxes. The opening of a paper carton is generally connected by a perforation, and when used, the perforation is torn off to remove the tissue paper (including sanitary tissue paper and wipers). However, this poses hygiene issues, such as the outer perforation tearing when the carton is torn off, and the opening being left open once the carton is torn off, allowing foreign objects to get in from the outside.

[0005] In addition, when removing the tissue, the unevenness of the perforated tearing section can damage the tissue, which is particularly noticeable with spunlace nonwoven fabrics, where the fibers that make up the tissue have a higher degree of freedom of movement with each other than paper.

[0006] Furthermore, if the surface of a rectangular paper carton where the opening is located (for example, the top surface) is not integrated with the side surface (if the top surface can be opened and closed), when removing the tissue paper, friction between the tissue paper and the edge of the opening causes the surface of the paper carton where the opening is located (the top surface) to follow, resulting in a gap between the top surface and the side surface and making removal difficult.

[0007] Therefore, an object of the present disclosure is to provide a tissue paper storage box that can ensure excellent ease of removal of tissue paper and allows the tissue paper to be used hygienically. [Means for solving the problem]

[0008] The inventors conducted extensive research and discovered that by cutting the opening in the shape of the opening from the beginning, rather than by separating it from a perforation, it is possible to prevent the aforementioned decrease in ease of removal due to separation, and by providing a lid, it is possible to use the container hygienically, which led to the completion of the present invention.

[0009] Furthermore, we found the optimal conditions for the position and size of the insert piece and insert port that secure the top and side surfaces so that the surface (top surface) of the tissue paper storage box with the removal opening does not follow when the tissue paper is removed.

[0010] Specifically, the present invention provides the following:

[0011] In order to solve the above problems, a first aspect of the present invention is a tissue paper storage box that stores tissue paper in an internal storage space so that it can be removed in a pop-up manner, and is equipped with a front and rear portion that stand up on both sides of the storage space in the front-to-back direction, a pair of side portions that stand up on both sides of the storage space in the width direction, a top portion that has an opening and that bends and extends rearward from the upper edge of the front portion, closing the upper part of the storage space in an openable and closable manner, and from which the tissue paper can be removed from the opening, and a lid portion that is tiltably supported on the upper edge of the rear portion, bends and extends forward from the upper edge of the rear portion, covering the opening on the top portion from above, and that can be tilted upward from the closed state to change to an open state in which the opening is opened.

[0012] A second aspect of the present invention is a tissue paper storage box of the first aspect described above, comprising a pair of first flaps that bend inward in the width direction from the upper edges of the pair of side portions and are positioned below the top portion, a pair of insertion slots that extend in the front-to-back direction and open upward and are provided at the bend between the pair of side portions and the pair of first flaps, and a pair of insertion pieces that bend downward from both end edges in the width direction of the top portion and are inserted into the pair of insertion slots.

[0013] A third aspect of the present invention is a tissue paper storage box of the second aspect, wherein the front-to-back length of the pair of insert pieces is set to 30% to 45% of the front-to-back length of the upper edges of the pair of side portions, and the distance from the front ends of the upper edges of the pair of side portions to the front-to-back center positions of the pair of insert pieces is set to 65% to 75% of the front-to-back length of the upper edges.

[0014] A fourth aspect of the present invention is a tissue paper storage box according to any one of the first to third aspects, comprising a second flap that bends downward from the rear edge of the upper surface portion and is positioned in front of the rear surface portion, and a pair of notches that extend inward in the width direction from both widthwise ends of the bent portion between the upper surface portion and the second flap, and the rear ends of the pair of first flaps are inserted into the pair of notches to restrict the upward movement of the second flaps.

[0015] A fifth aspect of the present invention is a tissue paper storage box according to any one of the first to fourth aspects, wherein the protrusion of the convex portion located on the edge of the outlet and protruding toward the inside of the outlet is 0.2 mm or less.

[0016] A sixth aspect of the present invention is a tissue paper storage box according to any one of the first to fifth aspects, wherein the width of the opening in the upper surface portion is set to 78% to 83% of the width of the tissue paper. [Effects of the Invention]

[0017] According to the present disclosure, excellent ease of removal of tissue paper can be ensured, and the tissue paper can be used hygienically. [Brief explanation of the drawings]

The front-to-back direction (depth direction) of the tissue paper storage box 10 is the direction along arrow Y in the figure, with arrow Y indicating the forward direction (near side). The width direction (left-to-right direction) of the tissue paper storage box 10 is the direction along arrow Z in the figure, with arrow Z indicating the left side when viewing the tissue paper storage box 10 from the front side.

[0021] Fig. 1 is a perspective view of a tissue paper storage box 10 according to one embodiment of the present invention. Fig. 2 is an expanded plan view of the tissue paper storage box 10 according to one embodiment of the present invention. Fig. 3 is an enlarged view of part III in Fig. 2. Fig. 4 is a perspective view of a corner of the tissue paper storage box 10 of Fig. 1 as viewed from the direction of arrow IV.

[0022] As shown in Figure 1, the tissue paper storage box 10 according to this embodiment is a tissue paper storage box 10 that stores stacked tissue paper 1 in a pop-up style so that it can be removed. Inside the tissue paper storage box 10, a storage space 11 for storing the tissue paper 1 is defined.

[0023] The thin paper 1 of the present invention includes, for example, sanitary thin paper such as tissue paper, toilet paper, paper towels, table napkins, kitchen paper, and kitchen towels, as well as paper or nonwoven wipers. The thin paper 1 may be made of paper, natural fiber, synthetic fiber, or the like, but examples include nonwoven fabrics such as meltblown nonwoven fabrics, spunlace nonwoven fabrics, and composite nonwoven fabrics formed by laminating these. The effect is particularly pronounced with spunlace nonwoven fabrics, with the effect being even more pronounced when the basis weight is 30 gsm to 70 gsm and the thickness is 0.3 mm to 0.45 mm.

[0024] 1 and 2, the tissue paper storage box 10 is formed by folding a single sheet of cardboard (plate-shaped body) called a carton blank. The tissue paper storage box 10 comprises a storage box body 12 for storing tissue paper 1, and a lid portion 13 supported on the storage box body 12 so as to be tiltable.

[0025] The paperboard (plate-shaped body) serving as the base material of the thin paper storage box 10 is paperboard for paper containers, and in particular, white paperboard is preferred. Its basis weight is 320 g / m 2 ~450 g / m 2 is preferred.

[0026] In this embodiment, the storage box body 12 is a rectangular parallelepiped box body, and includes a lower surface portion 14, a front surface portion 15, a rear surface portion 16, a pair of left and right side surface portions (a pair of side surface portions) 17, 18, a pair of left and right first flaps (a pair of first flaps) 19, 20, a pair of left and right insertion ports (a pair of insertion ports) 21, 22, an upper surface portion 23, a second flap 24, a pair of left and right slits (a pair of cutout portions) 36a, 36b, and a pair of left and right insertion pieces (a pair of insertion pieces) 25, 26. In this embodiment, the length L1 in the front-rear direction of the storage box body 12 is longer than the length L2 in the vertical direction, and the length L3 in the width direction is longer than the length L1 in the front-rear direction (L2 < L1 < L3). Note that the relationship among the length L1 in the front-rear direction, the length L2 in the vertical direction, and the length L3 in the width direction of the storage box body 12 is not limited to the above.

[0027] The lower surface portion 14 of the storage box body 12 is a portion that partitions the lower part of the storage space 11, and in this embodiment, it is formed into a rectangular plate shape that is long in the width direction by combining a plurality (four) of plate-shaped portions 14a to 14d (see FIG. 2).

[0028] The front surface portion 15 of the storage box body 12 is a portion that partitions the front of the storage space 11, bends upward from the front edge of the lower surface portion 14, and stands up along the front edge of the lower surface portion 14. That is, the front surface portion 15 stands up in front of the storage space 11. The front surface portion 15 is formed in a plate shape that intersects the front-rear direction. In this embodiment, the front surface portion 15 is formed in a rectangular plate shape that is long in the width direction. At the center in the width direction of the upper end portion of the front surface portion 15, a lid cutout portion 27 that is cut out downward (semicircularly in this embodiment) from the upper edge of the front surface portion 15 is formed. The lid cutout portion 27 is used when opening the lid portion 13. From the lower edge of the front surface portion 15, the plate-shaped portion 14a that constitutes the lower surface portion 14 extends rearward in a bent manner. That is, the lower edge of the front surface portion 15 and the front edge of the lower surface portion 14 (plate-shaped portion 14a) are continuous with each other.

[0029] The rear surface portion 16 of the storage box main body 12 is a portion that defines the rear of the storage space 11, and is bent from the rear edge of the lower surface portion 14 and stands up along the rear edge of the lower surface portion 14. That is, the rear surface portion 16 stands up behind the storage space 11. The front surface portion 15 and the rear surface portion 16 stand up on both sides of the storage space 11 in the front-to-rear direction. The rear surface portion 16 is formed in a plate shape that intersects with the front-to-rear direction. In this embodiment, the rear surface portion 16 is formed in a rectangular plate shape that is elongated in the width direction. From the lower edge of the rear surface portion 16, a plate-like portion 14b that constitutes the lower surface portion 14 bends and extends forward. That is, the lower edge of the rear surface portion 16 and the rear edge of the lower surface portion 14 (plate-like portion 14b) are continuous with each other.

[0030] The left and right side portions 17, 18 of the storage box main body 12 are portions that partition both sides (left and right sides) of the storage space 11 in the width direction, and are bent from both widthwise edges of the bottom surface portion 14 and stand up along both widthwise edges of the bottom surface portion 14. In other words, the left and right side portions 17, 18 stand up on both widthwise sides of the storage space 11. The left and right side portions 17, 18 are formed in the shape of plates that intersect with the width direction. In this embodiment, the left and right side portions 17, 18 are formed in the shape of rectangular plates that are long in the front-to-rear direction. From the lower edges of the left and right side portions 17, 18, plate-like portions 14c, 14d that constitute the bottom surface portion 14 are bent and extend inward in the width direction (toward each other). That is, the lower edge of the left side surface portion 17 and the left edge of the bottom surface portion 14 (plate-shaped portion 14c) are continuous with each other, and the lower edge of the right side surface portion 18 and the right edge of the bottom surface portion 14 (plate-shaped portion 14d) are continuous with each other. The left and right side surface portions 17, 18 also bend and extend rearward from both left and right end edges of the front surface portion 15. That is, the front edge of the left side surface portion 17 and the left edge of the front surface portion 15 are continuous with each other, and the front edge of the right side surface portion 18 and the right edge of the front surface portion 15 are continuous with each other. The rear surface portion 16 also bends and extends rightward from the rear edge of the left side surface portion 17. That is, the rear edge of the left side surface portion 17 and the left edge in the width direction of the rear surface portion 16 are continuous with each other. The rear edge of the right side surface portion 18 is adhered to a glue tab portion 28 (see FIG. 2) that extends continuously from the right edge of the rear surface portion 16 in the width direction.

[0031] The left and right first flaps 19, 20 of the storage box body 12 bend inward in the width direction from the upper edges of the left and right side surface portions 17, 18 and extend in the front-to-rear direction along the upper edges of the left and right side surface portions 17, 18. That is, the outer edge of the left first flap 19 in the width direction and the upper edge of the left side surface portion 17 are continuous with each other, forming a bent portion 30a between the left first flap 19 and the left side surface portion 17. Furthermore, the outer edge of the right first flap 20 in the width direction and the upper edge of the right side surface portion 18 are continuous with each other, forming a bent portion 30b between the right first flap 20 and the right side surface portion 18. That is, the bent portions 30a, 30b are bent portions 30a, 30b between the pair of side surface portions 17, 18 and the pair of first flaps 19, 20.

[0032] The left and right insertion openings 21, 22 of the storage box body 12 are openings for inserting the left and right insertion pieces 25, 26, and are provided at bending portions 30a, 30b between the left and right first flaps 19, 20 and the left and right side surface portions 17, 18. The left and right insertion openings 21, 22 are formed as elongated holes extending in the front-rear direction and open upward. The front-rear length of the left and right insertion openings 21, 22 is set to a length that allows the left and right insertion pieces 25, 26 to be inserted. In this embodiment, the front-rear length of the left and right insertion openings 21, 22 is set to be slightly longer than the front-rear length L4 of the left and right insertion pieces 25, 26, which will be described later. In addition, the front-to-rear positions of the left and right insertion openings 21, 22 relative to the bending portions 30a, 30b of the left and right first flaps 19, 20 and the left and right side portions 17, 18 are set to positions where the left and right insertion pieces 25, 26 can be inserted (positions facing the left and right insertion pieces 25, 26).

[0033] The top surface 23 of the storage box body 12 is a portion that closes the top of the storage space 11 in an openable / closable manner and is formed in a plate shape that intersects in the vertical direction. In this embodiment, the top surface 23 is formed in a rectangular plate shape that is elongated in the width direction. The top surface 23 bends and extends rearward from the upper edge of the front surface 15. That is, the front edge of the top surface 23 and the upper edge of the front surface 15 are continuous with each other. The top surface 23 is tiltably supported on the upper edge of the front surface 15 and closes the storage space 11 from above. The storage space 11 can be opened upward by tilting the rear end of the top surface 23 forward and upward. That is, the top surface 23 closes the top of the storage space 11 in an openable / closable manner. Both widthwise ends of the top surface 23 are located above the left and right first flaps 19, 20. That is, the left and right first flaps 19, 20 are located below the top surface 23. A lid flap insertion hole 31 into which a lid flap 29 (described later) of the lid portion 13 can be inserted is formed in the widthwise center of the front end edge of the top surface portion 23. The lid flap insertion hole 31 is formed longer on both sides in the widthwise direction than the lid cutout portion 27 of the front surface portion 15, and is connected to the lid cutout portion 27.

[0034] The top surface 23 has a take-out opening 32 through which the tissue paper 1 can be taken out of the storage space 11. The take-out opening 32 has a generally oval central portion 32a and left and right extension portions 32b, 32b that extend symmetrically from the central portion 32a to both sides in the width direction and are shorter in the front-to-back direction than the central portion 32a, and is formed as a long hole that is long in the width direction. The center of the central portion 32a of the take-out opening 32 is located at the center of the top surface 23 in the width direction and the center in the front-to-back direction.

[0035] The widthwise length L5 of the take-out opening 32 is set to 72% to 88% of the total widthwise length L6 of the thin paper 1, and preferably 78% to 83%.

[0036] The access opening 32 on the top surface 23 is pre-formed in an open state before the tissue paper storage box 10 is completed as a product. In this embodiment, a perforated cut portion is provided around the periphery of the access opening 32 on the top surface 23 before the access opening 32 is formed. The access opening 32 is formed by neatly cutting away the area inside the perforations (the area inside the access opening 32) along the perforations when the tissue paper storage box 10 is in the state of a single sheet of cardboard before it is assembled, or after it is assembled. In this way, the access opening 32 is pre-formed in an open state before the tissue paper storage box 10 is completed as a product. When the area inside the perforations (the area inside the access opening 32) is cut away, a plurality of protrusions 34 (portions cut along the perforations) protruding toward the inside of the access opening 32 remain on the edge 33 of the access opening 32 (see FIG. 3). As shown in FIG. 3, the amount of protrusion L10 of the multiple protrusions 34 from the edge 33 of the access opening 32 toward the inside of the access opening 32 is kept to 0.2 mm or less (only one protrusion 34 is shown in FIG. 3). In this embodiment, the access opening 32 is formed by providing a perforated cut portion around the access opening 32 on the top surface 23 before the access opening 32 is formed and then cutting away the area inside the perforation, but this is not limited to this. For example, the access opening 32 may be formed by punching a predetermined position on the top surface 23 using a press or the like when the tissue paper storage box 10 is in the state of a single sheet of cardboard before assembly.

[0037] The second flap 24 of the storage box body 12 bends downward from the rear edge of the top surface portion 23 and extends widthwise along the rear edge of the top surface portion 23. In other words, the upper edge of the second flap 24 and the rear edge of the top surface portion 23 are continuous with each other, forming a bent portion 35 between the second flap 24 and the top surface portion 23. The second flap 24 is located in front of the upper end of the rear surface portion 16.

[0038] As shown in FIG. 2, the left and right slits 36a, 36b of the storage box body 12 are provided at both widthwise ends of the bent portion 35 between the second flap 24 and the top surface portion 23. The left and right slits 36a, 36b are formed as notches extending inward in the widthwise direction from both widthwise ends of the bent portion 35 between the second flap 24 and the top surface portion 23. As shown in FIG. 4, the rear ends of the left and right first flaps 19, 20 are inserted into the left and right slits 36a, 36b. The second flap 24 is locked by the insertion (biting) of the left and right first flaps 19, 20 into the left and right slits 36a, 36b. The rear ends of the left and right first flaps 19, 20 are inserted into the left and right slits 36a, 36b, restricting the upward movement of the second flap 24 and thereby restricting the upward tilting of the rear end of the top surface portion 23. 4 shows the state in which the right-side first flap 20 is inserted into the right-side slit 36b, but the left-side first flap 19 is also inserted into the left-side slit 36a, just like the right-side. Also, in this embodiment, left and right slits (cutouts) 36a, 36b are provided at both ends in the width direction of the bent portion 35 between the second flap 24 and the top surface portion 23, but the cutouts are not limited to slits and may have other configurations as long as they are cut out so that the rear ends of the left and right first flaps 19, 20 can be engaged.

[0039] The left and right insertion pieces 25, 26 of the storage box body 12 are bent downward from both widthwise edges of the top surface portion 23 and inserted into the left and right insertion openings 21, 22. The left and right insertion pieces 25, 26 are provided integrally with the top surface portion 23.

[0040] The front-to-back length L4 of the left and right insertion pieces 25, 26 is set to 27% to 50% of the front-to-back length L7 of the upper edges of the left and right side portions 17, 18 (in this embodiment, approximately the same as the front-to-back length L1 of the storage box main body 12 and the front-to-back length L8 of the top surface portion 23), and preferably set to 30% to 45%.

[0041] The distance L9 from the front ends 37 of the upper edges of the left and right side portions 17, 18 to the center position of the left and right insertion pieces 25, 26 in the front-to-rear direction is set to 63% to 77% of the length L7 of the upper edges of the left and right side portions 17, 18 in the front-to-rear direction, and preferably set to 65% to 75%. In other words, the center position of the left and right insertion pieces 25, 26 in the front-to-rear direction is set between the position that divides the upper edges of the left and right side portions 17, 18 in the front-to-rear direction at 63:37 (front side:rear side) and the position that divides it at 77:23, and preferably between the position that divides it at 65:35 and the position that divides it at 75:25, with the total length L7 of the upper edges of the left and right side portions 17, 18 being 100%.

[0042] As shown in FIGS. 1 and 2 , the lid 13 is tiltably supported on the upper edge of the rear surface 16, allowing the access opening 32 of the top surface 23 to be opened and closed. The lid 13 bends and extends forward from the upper edge of the rear surface 16, covering the entire top surface 23 from above and thereby covering the access opening 32 of the top surface 23 from above. The lid 13 can be placed in a closed state (not shown) in which the access opening 32 of the top surface 23 is covered from above, or in an open state (see FIG. 1 ) in which the free end 38 of the lid 13 is tilted rearward and upward from the closed state to expose the access opening 32. A lid flap 29 is provided in the center of the width of the lid 13 on the free end 38 side. The lid flap 29 is formed to a length that allows it to be inserted into the lid flap insertion hole 31 on the front edge of the top surface 23, and bends and extends downward from the free end 38 of the lid 13 (downward in the closed state).

[0043] In the tissue paper storage box 10 configured as described above, the access opening 32 on the top surface 23 is pre-formed in an open state before the tissue paper storage box 10 is completed as a product. This allows the edges of the access opening 32 to be pre-formed smoothly (flat), unlike when perforations are provided on the top surface 23 and the user of the tissue paper 1 cuts away the area inside the perforations to form the access opening for the tissue paper 1. For example, as in this embodiment, the protrusion amount L10 of the multiple protrusions 34 from the edge 33 of the access opening 32 to the inside of the access opening 32 can be kept to 0.2 mm or less. This reduces friction by preventing the tissue paper 1 from catching on the edge 33 of the access opening 32 when the tissue paper 1 is being removed, thereby reducing upward movement of the top surface 23 and ensuring excellent accessibility for the tissue paper 1.

[0044] In addition, since it is possible to prevent the tissue paper 1 from getting caught on the edge 33 of the removal opening 32 when removing the tissue paper 1, it is possible to prevent damage (such as tearing) to the tissue paper 1 caused by getting caught on the edge 33 of the removal opening 32 (for example, the unevenness of the perforations).

[0045] Furthermore, since the protrusion amount L10 of the multiple convex portions 34 from the edge portion 33 of the removal opening 32 to the inside of the removal opening 32 is 0.2 mm or less, as described in the examples below, the upper surface portion 23 is prevented from moving upward when the tissue paper 1 is removed, ensuring excellent removal properties of the tissue paper 1 and reducing damage to the tissue paper 1.

[0046] In addition, since the upper surface portion 23 can be prevented from moving upward when the tissue paper 1 is removed, gaps can be prevented from occurring between the rear surface portion 16 and the left and right side surface portions 17, 18 and the upper surface portion 23, allowing the tissue paper 1 to be used hygienically.

[0047] The lid 13 can be placed in a closed state, covering the access opening 32 on the top surface 23 from above, or in an open state, tilting upward from the closed state to open the access opening 32. When the tissue paper 1 is not in use, the lid 13 is placed in the closed state to cover the access opening 32 on the top surface 23 from above, and when the tissue paper 1 is in use, the lid 13 is placed in the open state to open the access opening 32 and remove the tissue paper 1. This allows the tissue paper 1 to be used hygienically.

[0048] Furthermore, left and right insertion openings 21, 22 are provided at bends 30a, 30b between left and right first flaps 19, 20 and left and right side sections 17, 18, and left and right insertion pieces 25, 26 integrally formed on top section 23 are inserted into left and right insertion openings 21, 22. This further reduces the upward movement of top section 23 when tissue paper 1 is removed upward, thereby reducing gaps between rear section 16 and left and right side sections 17, 18 and top section 23, allowing tissue paper 1 to be used hygienically.

[0049] Additionally, the front-to-rear length L4 of the left and right insertion pieces 25, 26 is set to 30% to 45% of the front-to-rear length L7 of the upper edges of the left and right side portions 17, 18, and the distance L9 from the front ends 37 of the upper edges of the left and right side portions 17, 18 to the center positions of the left and right insertion pieces 25, 26 in the front-to-rear direction is set to 65% to 75% of the front-to-rear length L7 of the upper edges of the left and right side portions 17, 18. Therefore, as described in the examples below, when the tissue paper 1 is removed upward, the upper surface portion 23 can be prevented from moving upward, allowing the tissue paper 1 to be used hygienically.

[0050] Left and right slits 36a, 36b are provided at both widthwise ends of the bent portion 35 between the second flap 24 and the top surface 23, and the rear ends of the left and right first flaps 19, 20 are inserted into the left and right slits 36a, 36b. The rear ends of the left and right first flaps 19, 20 are inserted into the left and right slits 36a, 36b to restrict the upward movement of the second flap 24, thereby restricting the upward tilt of the rear end of the top surface 23. This further reduces the upward movement of the top surface 23 when the tissue paper 1 is removed upward, thereby reducing the occurrence of gaps between the rear surface 16 and the left and right side surfaces 17, 18 and the top surface 23, allowing the tissue paper 1 to be used hygienically.

[0051] Thus, according to this embodiment, excellent ease of removal of the thin paper 1 can be ensured, and the thin paper 1 can be used hygienically.

[0052] Additionally, the widthwise length L5 of the take-out opening 32 of the top surface 23 is set to 78% to 83% of the widthwise length L6 of the tissue paper 1. Therefore, as described in the examples below, when tissue paper 1 is taken out, the next piece of tissue paper 1 falls into the storage space 11 of the storage box body 12, which is known as "drop-back," and this can be prevented.

[0053] The present invention will be described below with reference to examples, but the present invention is not limited to these examples in any way.

[0054] The tissue paper storage boxes of Examples 1 to 7 and Comparative Examples 1 to 4 were produced.

[0055] The first take-out property is an evaluation of the difficulty of the upper surface portion 23 to move upward when the tissue paper 1 is taken out upward. ◎: Almost no tracking ○: There is occasional tracking, but it is not a problem ×: Easy to follow

[0056] The second removability is evaluated by a sensory test to measure the resistance encountered when grasping and removing the tissue paper 1 (whether it can be pulled out smoothly), and also includes evaluations of the first removability and the third removability described below. ◎: Good ○:Normal ×: Bad

[0057] The third removability was an evaluation of damage to the tissue paper 1 when the tissue paper 1 was removed. ◎: Almost no damage ○: Damage is rare but not a problem ×: Easy to break

[0058] The fourth item, ease of removal, is an evaluation of the difficulty of the next tissue paper 1 dropping back when the tissue paper 1 is removed. ◎: Almost no drop back ○: Drop backs are rare but not a problem ×: Easy to drop back

[0073] As shown in Table 1 above, in Examples 1 to 7 in which the "front-to-back center position of the left and right insertion pieces 25, 26" is set between the position dividing the total length L7 of the upper edges of the left and right side portions 17, 18 into 63:37 and the position dividing it into 77:23, and the "front-to-back length L4 of the left and right insertion pieces 25, 26" is set to 27% to 50% of the total length L7 of the upper edges of the left and right side portions 17, 18, it was confirmed that when the tissue paper 1 is removed upward, the upper surface portion 23 does not easily follow (first removal ability: "◎" or "○"), and the tissue paper 1 can be removed smoothly (second removal ability: "◎" or "○"). On the other hand, in Comparative Example 1, in which the "center position of the left and right insert pieces 25, 26 in the front-to-back direction" was set at a position that divided the total length L7 of the upper edges of the left and right side portions 17, 18 into 40:60, and the "length L4 of the left and right insert pieces 25, 26 in the front-to-back direction" was set to 25% of the total length L7 of the upper edges of the left and right side portions 17, 18, it was confirmed that when the tissue paper 1 was removed upward, the upper surface portion 23 tended to follow (first removal property: "x"), and the tissue paper 1 could not be removed smoothly (second removal property: "x").

On the other hand, in Comparative Example 2, in which the "widthwise length L5 of the take-out opening 32" was set to 60% of the total widthwise length L6 of the tissue paper 1, it was confirmed that the widthwise length L5 of the take-out opening 32 was too narrow and the tissue paper 1 could not be smoothly taken out (second take-out property: "×"). In addition, in Comparative Example 4, in which the "widthwise length L5 of the take-out opening 32" was set to 96% of the total widthwise length L6 of the tissue paper 1, it was confirmed that the widthwise length L5 of the take-out opening 32 was too long (too wide) and was easy to drop back (fourth take-out property: "×").

[0076] In addition, in Examples 1 and 2, in which the "widthwise length L5 of the take-out opening 32" was set to 78% to 83% of the total widthwise length L6 of the tissue paper 1, it was confirmed that the tissue paper 1 could be taken out well (second take-out property: "◎") and there was almost no drop-back (fourth take-out property: "◎").On the other hand, in Example 6, in which the "widthwise length L5 of the take-out opening 32" was set to 72% of the total widthwise length L6 of the tissue paper 1, it was confirmed that the tissue paper 1 could be taken out normally (second take-out property: "○"), but was more difficult to take out compared to Examples 1 and 2.In addition, in Example 7, in which the "widthwise length L5 of the take-out opening 32" was set to 88% of the total widthwise length L6 of the tissue paper 1, it was confirmed that there was rare drop-back compared to Examples 1 and 2 (fourth take-out property: "○"). In other words, it was confirmed that excellent take-out ability of the thin paper 1 can be reliably ensured by setting the "widthwise length L5 of the take-out opening 32" to 78% to 83% of the total widthwise length L6 of the thin paper 1.

[0077] In addition, in Examples 1 to 7, in which the "protrusion amount L10 of the convex portion 34 of the edge 33 of the dispensing opening 32" was set to 0.2 mm or less, it was confirmed that the tissue paper 1 was less likely to break (third removability: "◎" or "◯") and could be smoothly removed (second removability: "◎" or "◯"). On the other hand, in Comparative Example 3, in which the "protrusion amount L10 of the convex portion 34 of the edge 33 of the dispensing opening 32" was set to 0.5 mm, it was confirmed that the tissue paper 1 got caught on the convex portion 34 of the edge 33 of the dispensing opening 32, making it difficult to remove the tissue paper 1 smoothly (second removability: "×") and that the tissue paper 1 was easily damaged (third removability: "×"). In other words, it was confirmed that setting the "protrusion amount L10 of the convex portion 34 of the edge 33 of the dispensing opening 32" to 0.2 mm or less is reliably effective in ensuring excellent removability of the tissue paper 1.
