As shown in FIG. 1, the toilet paper package 1 of the first embodiment is formed of a laminate 10 in which a plurality of toilet papers 20 are stacked, and a package 40 in which the laminate 10 is placed inside.

<Laminated body>
As shown in FIG. 2, the laminate 10 is formed into a rectangular parallelepiped shape. In this specification, for ease of understanding, when viewed from the arrow in FIG. The right side facing the left side is called the fourth side 14, the top side is called the fifth side 15, and the bottom side facing the top side is called the sixth side 16.

The laminate 10 is formed by folding and stacking a plurality of toilet papers 20 in a pop-up manner. Although the toilet paper 20 of the first embodiment is formed of two plies by laminating two sheets of toilet paper, it can also be formed of three or four plies by laminating three or four sheets of toilet paper.

The length of the laminate 10 is not particularly limited, but the laminate 10 of the first embodiment has a length in the width direction, that is, a distance between the third surface 13 and the fourth surface 14 of approximately 105 mm, and a length in the front-back direction. The length, that is, the distance between the first surface 11 and the second surface 12, is approximately 110 mm, and the length in the vertical direction, that is, the distance between the fifth surface 15 and the sixth surface 16, is approximately 220 mm. Thereby, the package 40 can be easily attached to an existing toilet holder via the engaging portion 39 of the package 40.

As shown in FIG. 3, the folded edge 21A of the toilet paper 21 is located on the left side, the front side part 21B extends from the folded edge 21A to the right front, and the rear side part 21C extends from the folded edge 20A to the right rear. It is formed by

The folded edge 22A of the toilet paper 22 adjacent to the front side of the toilet paper 21 is located on the right side, the front side portion 22B extends forward left from the folded edge 22A, and the rear side portion 22C extends rearward left from the folded edge 22A. It is formed as follows. Further, the folded edge 23A of the toilet paper 23 adjacent to the rear side of the toilet paper 21 is located on the right side, the front side part 23B extends from the folded edge 23A to the front left, and the rear side part 23C extends from the folded edge 23A to the rear left. It is formed by extending to. In FIG. 3, three adjacent sheets of toilet paper 20 are shown with reference symbols 21, 22, and 23, respectively, for ease of explanation.

The front side 21B of the toilet paper 21 is inserted between the front side 22B and the rear side 22C of the toilet paper 22, and the rear side 21C of the toilet paper 21 is inserted between the front side 23B and the rear side 23C of the toilet paper 23. inserted in between. Thereby, when the toilet paper 20 located at the frontmost side of the stacked body 10 is pulled out to the front side, the toilet paper 20 adjacent to the rear side of this toilet paper 20 can be pulled out to the front side.

The basis weight of each sheet of thin paper constituting each ply of the toilet paper 20 is set to 10.0 to 25.0 g/m ² . Thereby, sufficient tear resistance and good texture of the toilet paper 20 can be ensured, and sufficient water-disintegrability can be maintained. The basis weight is a value measured in accordance with JIS P 8124 (1998).

Each sheet of toilet paper 20 has a thickness of 100 to 150 μm. Thereby, it is possible to ensure that the toilet paper 20 has sufficient resistance to tearing and has a good texture. The paper thickness was measured using a dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho) under the same conditions after thoroughly conditioning the humidity of the test piece under the conditions of JIS P 8111 (1998). This is the value. More specifically, after confirming that there is no dirt, dust, etc. between the plunger and the measuring table, lower the plunger onto the measuring table, move the memory of the dial thickness gauge, and set the zero point. Next, raise the plunger and place the test piece on the measuring table, then lower the plunger slowly and read the gauge at that time. At the time of measurement, care was taken to ensure that the terminal of the metal plunger (circular plane with a diameter of 10 mm) struck perpendicularly to the plane of the paper. Note that the load during this paper thickness measurement was approximately 70 gf.

The dry tensile strength of the toilet paper 20 in the longitudinal direction is set to 150 to 800 cN/25 mm. Thereby, it is possible to ensure that the toilet paper 20 has sufficient resistance to tearing and has a good texture.

The wet tensile strength of the toilet paper 20 in the lateral direction is set to 15 to 75 cN/25 mm. As a result, it is possible to improve the durability of wiping in a wet state and the sense of security when wiping after using a so-called shower toilet. Further, the wet tensile strength in the lateral direction of the toilet paper 20 is set to be 0.09 or more relative to the dry tensile strength in the lateral direction. This makes it possible to achieve both good feel and durability.

The longitudinal direction of the toilet paper 20 is also called the MD direction and is the flow direction during paper making, and the lateral direction of the toilet paper 20 is also called the CD direction and is perpendicular to the flow direction (MD direction) during paper making. It is the direction.

The dry tensile strength is a value measured in accordance with JIS P 8113 (2006). More specifically, a test piece is used that is cut to a width of about 25 mm (±0.5 mm) x a length of about 150 mm in both the vertical and horizontal directions. The test piece is measured in multiple plies. The test machine used is Minebea Co., Ltd.'s load cell tensile tester TG-200N and an equivalent machine. Note that the gripping interval is set to 100 mm, and the pulling speed is set to 100 mm/min. Measurement is performed by tightening both ends of the test piece into the grips of the testing machine, applying a tensile load to the paper piece in the vertical direction, and reading the indicated value (digital value) when the paper breaks. Five sets of samples were prepared for each of the longitudinal and transverse directions, and each sample was measured five times, and the average of the measured values was taken as the dry tensile strength in each direction. The dry tensile strength of the product was measured by stacking multiple sheets according to the number of plies of the product. The dry tensile strength of the base paper was also measured by stacking multiple sheets according to the number of plies of the product.

Wet tensile strength is a value measured in accordance with JIS P 8135 (1998). Specifically, a test piece is used that is cut to a width of about 25 mm (±0.5 mm) x a length of about 150 mm in both the vertical and horizontal directions. If the tissue paper has multiple plies, measure the multiple plies as they are. The test machine used is Minebea Co., Ltd.'s load cell tensile tester TG-200N and an equivalent machine. Note that the gripping interval is set to 100 mm, and the pulling speed is set to 50 mm/min. The test piece used was one that had been cured for 10 minutes in a dryer at 105°C. After tightening both ends of the test piece to the grips of the testing machine, apply water horizontally to the center of the test piece in a width of about 10 mm using a flat brush moistened with water, and then immediately apply water in the vertical direction to the paper piece. Measurement is performed by applying a tensile load to the paper and reading the indicated value (digital value) when the paper breaks. Five sets of samples are prepared for each of the longitudinal and transverse directions and measured five times each, and the average of the measured values is taken as the wet tensile strength in each direction. Wet tensile strength was also measured by stacking multiple sheets according to the number of plies in the product.

The softness of the toilet paper 20 is set to 1.8 to 3.5 cN/100 mm. Thereby, good softness of the toilet paper 20 can be ensured. Softness is a value measured based on the handle-o-meter method in accordance with JIS L 1096 E method (1990). However, the size of the test piece is 100 mm x 100 mm, and the clearance is 5 mm. Each ply is measured 5 times in the longitudinal and lateral directions, and the average value of all 10 measurements is taken as the average value. Note that softness is unitless, but considering the size of the test piece, cN/ It is sometimes expressed in units of 100 mm.

The water disintegration of the toilet paper 20 is set to 60 seconds or less. As a result, when the toilet paper 20 is disposed of under flushing water in a flush toilet or the like, the possibility that the toilet paper 20 will quickly unravel and clog the pipes is greatly reduced. Water degradability is a value measured in accordance with JIS P 4501 (1993). More specifically, a test piece that had been cured at 105°C for 3 minutes was prepared, a 300ml beaker containing 300ml of water (water temperature 20±5°C) was placed on a magnetic stirrer, and the rotation speed of the rotor was adjusted. Adjust to 600±10 revolutions/minute. A test piece with a side of 114±2 mm is placed in it, and a stopwatch is pressed. The rotational speed of the rotor drops to approximately 500 rotations due to the resistance of the test piece, and increases as the test piece loosens. When the rotation speed has recovered to 440 rotations, the stopwatch is stopped and the time is measured in seconds. The results of ease of unraveling are expressed as the average of 5 tests performed. The rotor is disk-shaped with a diameter of 35 mm and a thickness of 12 mm.

Raw material pulp for toilet paper 20 includes mechanical pulps such as ground wood pulp (GP), pressure-rised ground wood pulp (PGW), and thermomechanical pulp (TMP); semi-chemical pulp (CP), and softwood high-yield unbleached kraft. Chemical pulps such as pulp (HNKP), softwood bleached kraft pulp (NBKP), hardwood unbleached kraft pulp (LUKP), and hardwood bleached kraft pulp (LBKP); recovered paper pulps such as deinking pulp (DIP) and waste pulp (WP) Fibers other than pulp may be included.

One kind or two or more kinds of pulp can be selected and used. Preferably, it is a chemical pulp that does not contain fillers or foreign substances. In particular, a material containing more LBKP (also called L wood or hardwood pulp) than NBKP (also called N wood or softwood pulp) is used. That is, chemical pulp having a ratio of NBKP to LBKP (NBKP/LBKP) of 50/50 to 30/70 is suitable. Since the fiber thickness of NBKP is thicker than that of LBKP, the larger the amount of NBKP, the bulkier it becomes. Further, the raw material pulp may contain woody plants and herbs such as straw pulp, bamboo pulp, and kenaf pulp. Also, waste paper pulp may be blended, but since it is difficult for waste paper pulp to exhibit "softness", it is extremely desirable that it is composed only of virgin pulp NBKP and LBKP.

On the other hand, fibers other than pulp include polyester fibers such as polyethylene terephthalate, polybutylene terephthalate, and copolymers thereof, polyolefin fibers such as polyethylene, polypropylene, and polystyrene, acrylic fibers such as polyacrylonitrile, acrylic fibers such as modacrylic, Polyamide fibers such as nylon 6, nylon 66, and nylon 12, synthetic fibers such as polyvinyl alcohol fibers, polyvinylidene chloride fibers, polyvinyl chloride fibers, urethane fibers, semi-synthetic fibers such as triacetate fibers and diacetate fibers, and viscose rayon. , copper ammonia rayon, polynosic rayon, regenerated cellulose fibers such as lyocell, and chemical fibers such as regenerated fibers spun from a solution of collagen, alginic acid, chitin, etc., can be included. The polymer constituting the chemical fiber may be in the form of a homopolymer, modified polymer, blend, copolymer, or the like.

<Cylindrical packaging material>

As shown in FIG. 4, the cylindrical packaging material 30 is formed into a cylindrical shape by joining one side in the width direction of the planar packaging material 30A to the other side.

In this specification, in order to facilitate understanding, the front side of the cylindrical packaging material 30 is referred to as a front part 31, the surface opposite to the front part is referred to as a back part 32, and the left side is referred to as a left side in the direction of the arrow in FIG. It is called a surface part 33, and the right side opposite to the left side is called a right side part 34.

The left side part 33 of the cylindrical packaging material 30 has a folded part 33A formed on the inside so that the right side end of the left side part 33 forms a valley, and the right side part 34 has a folded part 33A formed so that the left side end of the right side part 34 forms a valley. A folding portion 34A is formed on the inside so that the folding portion 34A is formed on the inside. Moreover, the upper parts of the front part 31, the left side part 33, and the right side part 34 are open, and the lower parts of the front part 31, the left side part 33, and the right side part 34 are open.

In the front part 31 of the cylindrical packaging material 30, a breaking line 37 is formed at the center in the width direction and extends linearly in the vertical direction. Note that the breaking line 37 is formed to extend from the upper end to the lower end of a flat surface 41 of the packaging material 40, which will be described later. Thereby, the front part 31 is pulled in the width direction to break the break line 37 to form a draw-out opening, and the toilet paper 20 contained in the cylindrical packaging material 30 can be easily pulled out.

The basis weight of the packaging material 30A forming the cylindrical packaging material 30 is 50 to 200 g/m ² . If the basis weight is less than 50 g/m ² , it will be difficult to maintain the shape of the package 40 formed from the cylindrical packaging material 30, and if the basis weight is more than 200 g/m ² , it will be difficult to fold. It may become difficult to form the package 40 easily. Further, it is preferable that the packaging material 30A has a basis weight of 70 to 130 g/m ² . Thereby, the third surface 13 and fourth surface 14 of the laminate 10, whose number of stacked sheets has been reduced due to the drawer, can be folded into the left folding section 34A formed on the left side surface 43 of the package 40 and the right folding section 34A formed on the right side surface 44. The stacked body 10 can be supported by the portion 34A to prevent the stacked body 10 from falling downward.

The paper thickness of the packaging material 30A is 100 to 300 μm. If the paper thickness is less than 100 μm, it will easily tear if water droplets adhere to the surface, and if the paper thickness exceeds 300 μm, it may be difficult to fold and the package 40 may not be formed easily.

Further, it is preferable that the packaging material 30A is water-decomposable like the toilet paper 20. As a result, when the packaging material 30A is disposed of under flushing water in a flush toilet or the like, the possibility of the packaging material 30A quickly unraveling and clogging the pipes is greatly reduced.

Raw material pulp for packaging material 30A includes mechanical pulp such as ground wood pulp (GP), pressure-rised ground wood pulp (PGW), and thermomechanical pulp (TMP); semi-chemical pulp (CP), and softwood high-yield unbleached kraft. Chemical pulps such as pulp (HNKP), softwood bleached kraft pulp (NBKP), hardwood unbleached kraft pulp (LUKP), and hardwood bleached kraft pulp (LBKP); recovered paper pulps such as deinking pulp (DIP) and waste pulp (WP) Examples include.

One kind or two or more kinds of pulp can be selected and used. Preferably, it is a chemical pulp that does not contain fillers or foreign substances. In particular, a material containing more LBKP (also called L wood or hardwood pulp) than NBKP (also called N wood or softwood pulp) is used. That is, chemical pulp having a ratio of NBKP to LBKP (NBKP/LBKP) of 50/50 to 30/70 is suitable. Since the fiber thickness of NBKP is thicker than that of LBKP, the larger the amount of NBKP, the bulkier it becomes. Further, the raw material pulp may contain woody plants and herbs such as straw pulp, bamboo pulp, and kenaf pulp. Also, waste paper pulp may be blended, but since it is difficult for waste paper pulp to exhibit "softness", it is preferable that it is composed only of virgin pulp NBKP and LBKP.

The inner surface of the packaging material 30A is preferably coated with a starch adhesive, a resin heat sealing material, or the like. Thereby, for example, one side in the width direction of the packaging material 30A can be easily joined to the other side to easily form the cylindrical packaging material 30. In addition, when coating the inner surface of the wrapping paper 30A with a resin heat-sealing material or the like, it is preferable that the proportion of pulp in the wrapping paper 30A is 60% or more. This makes it possible to reduce the amount of discarded resin and reduce microplastics floating in the ocean.

<Toilet paper packaging>
As shown in FIG. 5, in order to form the package 40 of the toilet paper package 1, the folded part 33A of the left side part 33 and the folded part 34A of the right side part 34 of the cylindrical packaging material 30 are raised up. Shape into a rectangular parallelepiped with open top and bottom.

Next, the lower part of the cylindrical packaging material 30 made into a rectangular parallelepiped shape is caramelized, that is, the lower part of the front part 31 of the cylindrical packaging material 30 is folded toward the back part 32 side, and the lower parts of the left side part 33 and the right side part 34 are folded. The lower part of the cylindrical packaging material 30 is closed by folding it to the right side part 34 side and the left side part 33 side, respectively, and folding the lower part of the back part 32 to the front part 31 side to form the bottom surface 46 of the package 40. As a result, the bottom surface 46 of the package 40 is formed by laminating four layers of wrapping paper 30A, increasing the rigidity, and can suppress deformation due to the weight of the laminate 10 placed inside the package 40. In the first embodiment, before the laminate 10 is placed inside, the lower part of the rectangular parallelepiped-shaped cylindrical packaging material 30 is folded to form the bottom surface 46 of the package 40. The bottom surface 46 of the packaging body 40 can also be formed by folding the lower part of the rectangular parallelepiped-shaped cylindrical packaging material 30 after it has been packed inside.

In this specification, in order to facilitate understanding, when viewed from the arrow in FIG. The right side thereof is referred to as a right side surface 44, the surface on which a mounting portion 47 (described later) is formed is referred to as a top surface 45, and the surface opposite to the top surface 45 is referred to as a bottom surface 46.

As shown in FIG. 6, the laminate 10 is inserted from the top of the cylindrical packaging material 30 and placed on the bottom surface 46 of the packaging body 40. At this time, the stacking direction of the laminate 10 is inserted along the front-back direction, that is, the direction from the front surface 41 to the back surface 42 of the package 40, and the longitudinal direction of the laminate 10 is inserted in the vertical direction, that is, the package 40 Insert along the direction from the top surface 45 to the bottom surface 46 of. Note that the front part 31, back part 32, left side part 33, and right side part 34 of the cylindrical packaging material 30 facing the laminate 10 are the flat surface 41, the back surface 42, the left side 43, and the right side of the packaging body 40, respectively. Form 44. Further, as described above, the upper and lower ends of the break line 37 formed in the cylindrical packaging material 30 are located at the upper and lower ends of the plane 41 of the packaging body 40.

As shown in FIG. 7, the upper part of the cylindrical packaging material 30 is folded into a pillow shape, that is, the upper part of the left side part 33 of the cylindrical packaging material 30 is folded to the right side part 34 side, and the upper part of the right side part 34 is folded to the left side part 33 side. After folding, the upper part of the front part 31 and the upper part of the back part 32 are joined with glue or the like to form an extension part 38 to close the upper part of the cylindrical packaging material 30, and the top surface 45 of the packaging body 40 is closed. Form. Thereby, the package 10 can be prevented from falling off from the package 40.

As shown in FIG. 8, the extending portion 38 is bent downward at approximately the midpoint in the vertical direction, and the upper end portion of the extending portion 38 is joined to the lower portion of the extending portion 38 via glue or the like. Thereby, a substantially circular engagement portion 39 extending in the width direction above the top surface 45 of the package 40 can be formed.

The length of the package 40 is not particularly limited, but the length of the engagement part 39 of the package 40 in the width direction is set to 107 to 120 mm, and the inner diameter of the engagement part 39 is set to 25 to 45 mm. is preferable. A typical toilet paper holder is compatible with a toilet roll width of 107 to 114 mm, so that the toilet paper package 1 can be used by being attached to an existing toilet paper holder. If it is less than 107 mm, there is a possibility that it will fall off from the toilet paper holder during use, and if it exceeds 120 mm, it will be easy to hold onto the toilet paper holder, but it will be difficult to attach it.

The length in the width direction of the package 40 of the first embodiment is 109 mm, which is 3 to 5 mm longer than the length in the width direction of the laminate 10 to be packed, and the length in the front-rear direction is 109 mm. The length is 114 mm, which is 3 to 5 mm longer than the length in the width direction. Thereby, it is possible to suppress the collapse of the stacked body 10 whose volume has decreased due to the toilet paper 20 being pulled out.

As shown in FIG. 1 and the like, the stacking direction of the laminate 10 housed in the package 40 is provided along the front-rear direction, that is, the direction from the front surface 41 to the back surface 42 of the package 40. Thereby, all the laminated toilet paper 20 can be easily pulled out from the drawer opening formed by pulling and breaking the break line 37 formed on the front surface 41 of the package 40 in the width direction.

The longitudinal direction of the laminate 10 housed in the package 40 is provided along the vertical direction, that is, the direction from the top surface 45 to the bottom surface 46 of the package 40. Thereby, as shown in Table 1, the resistance to pulling out the toilet paper 20 can be suppressed, and even a person with a disability who cannot freely use one arm due to a disability can easily pull out and use the toilet paper 20.

<Measurement of withdrawal resistance>
(Measuring method)
The pull-out resistance in the vertically placed state (the state in which the longitudinal direction of the laminate 10 is arranged along the vertical direction) is formed on the front surface 41 of the package 40 by fixing the bottom surface 46 of the package 40 to a surface plate. Break the break line 37 to form an outlet, sandwich the vertical center of the toilet paper 20 in the stacked body 10 with a clip (Kokuyo Co., Ltd. double clip 25 mm width), and place the toilet paper 20 on the front side 41. On the other hand, the peak of the resistance value (gf) when pulled out in the normal direction was measured using a digital force gauge (Model: Z2-20N, manufactured by Imada Co., Ltd.). Note that the laminate 10 was made using 180 sets (360 pieces) of Elleair Audust tissue.

The pull-out resistance in the horizontally placed state (the state in which the longitudinal direction of the laminate 10 is provided along the width direction) is formed on the front surface 41 of the package 40 by fixing the left side surface 43 of the package 40 to a surface plate. Break the break line 37 to form an outlet, sandwich the center part of the toilet paper 20 in the width direction of the stacked body 10 with a clip (Kokuyo Co., Ltd. double clip 25 mm width), and insert the toilet paper 20 on the front side 41. On the other hand, the peak of the resistance value (gf) when pulled out in the normal direction was measured using a digital force gauge (Model: Z2-20N, manufactured by Imada Co., Ltd.). Note that the laminate 10 was made using 180 sets (360 pieces) of Elleair Audust tissue.

(Measurement result)
The average value of the pull-out resistance measured five times in the vertically placed state was 0.77 kgf, and the average value of the drawer resistance measured five times in the horizontally placed state was 1.04 kgf. It was found that the pull-out resistance in the vertically placed state was approximately 25% smaller than the pull-out resistance in the horizontally placed state.

As shown in FIG. 1 etc., the break line 37 formed on the front face 41 of the package 40 extends linearly in the vertical direction from the upper end to the lower end of the front face 41 at the center of the front face 41 in the width direction. There is. As a result, the resistance to pulling out the toilet paper 20 is further suppressed, and even a person with a disability who is unable to use one arm due to a disability can more easily pull out and use the toilet paper 20.

Next, a toilet paper package 1 according to a second embodiment will be described. Identical members are given the same reference numerals and their explanations will be omitted.

As shown in FIG. 9, the front face 41 of the package 40 of the toilet paper package 1 of the second embodiment has a substantially S-shaped shape at the center of the front face 41 in the width direction, for example, when viewed from the front. A breaking line 37A is formed which projects in an arc shape from the center toward the left side surface 43, and whose lower part projects in an arc shape from the center in the width direction toward the right side surface 44. The upper and lower ends of the breaking line 37A are located at the upper and lower ends of the plane 41 of the packaging material 40, and the radius of the upper and lower arcs is the same. Thereby, the resistance to draw out the toilet paper 20 is further suppressed, and the toilet paper 20 can be more easily pulled out and used even by a person with a disability who is unable to use one arm due to a disability. Further, it is possible to further suppress the collapse of the stacked body 10 whose volume has decreased due to the toilet paper 20 being pulled out.
