Description

[Technical field]

[0001] The present disclosure relates to tissue storage box packaging. [Background technology]

[0002] Nowadays, tissues are widely used in various aspects of daily life, not only for blowing your nose, but also for wiping off minor stains, as napkins, etc. Most general-purpose tissues are stored in paperboard storage boxes, and are commonly packaged in sets of five boxes wrapped in film.

[0003] In recent social circumstances, there is a demand for environmentally friendly, large-capacity tissues that can be replaced less frequently. Increasing the number of tissues per box reduces packaging materials and improves transportation efficiency. In order to supply large quantities to users at low cost, it is necessary to produce them using a multi-stand interfolder (multiple-row) processing machine.

[0004] Patent Document 1 discloses a compact box of tissues in which the height of the storage box per number of tissues stored is reduced. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2001-286414 A Summary of the Invention [Problem to be solved by the invention]

[0006] In storage boxes (tissue paper storage boxes) that store a large amount of tissues (tissue paper), the height of the storage box tends to increase as the number of tissues increases. However, if the height of the storage box is too high, the phenomenon in which tissues fall into the storage box when there are only a few tissues left (hereinafter referred to as the "drop back phenomenon") is more likely to occur. On the other hand, if the height of the storage box is made too low in order to prevent the drop back phenomenon, the initial removal of the tissues becomes difficult, and there is a possibility that the tissues may tear or two sheets may be removed in a row. In addition, if the basis weight or paper thickness is reduced or the paper strength is increased to prevent the tissues from tearing, the texture will be damaged.

[0007] In addition, the larger the capacity of a tissue paper storage box, the heavier it becomes, so the weight of a product (tissue paper storage box package) in which five large-capacity tissue paper storage boxes are packaged together in film also increases. For this reason, in a typical film package with a handle film, when the handle film is grasped and moved, the tissue paper storage box located at the height where the handle film is attached may deform, or the film (handle film and exterior film) may break.

[0008] Therefore, the present disclosure aims to provide a tissue paper storage box packaging body that can prevent deformation of the tissue paper storage box and breakage of the film even when packaging a large-capacity, compact tissue paper storage box that can reduce the occurrence of dropback, ensure the initial removal of the tissue paper, and reduce tearing of the tissue paper when removed. [Means for solving the problem]

[0009] In order to solve the above problems, the present disclosure provides a tissue paper storage box package including a plurality of tissue paper storage boxes stacked one on top of the other and storing tissue paper in a pop-up style so that it can be removed, an exterior film that packages the plurality of tissue paper storage boxes, and a handle film whose both ends are welded to the exterior film and function as handles when carried, wherein the direction in which the tissue paper is pulled out from the tissue paper storage box is the CD direction of the tissue paper, the tensile strength of the tissue paper in the pulling direction when dry is 100 gf / 25 mm or more and 200 gf / 25 mm or less, the number of sets of the tissue paper stored in the tissue paper storage box is 230 sets or more and 300 sets or less, the value expressed by the formula: (height of the tissue paper storage box (mm)) / (length of the tissue paper in the pulling direction (mm) / 2) is 0.6 or more and 0.75 or less, and the basis weight of the tissue paper storage box is 300 g / m 2 More than 400g / m 2 the thickness of the handle film is 50 μm or more and 60 μm or less, the width of the handle film is 40 mm or more and 60 mm or less, when a load of 3 kg is applied in the length direction to the handle film which is 50 mm wide and 100 mm long, the value expressed by the formula: ((length of the handle film under a load of 3 kg (mm) - 100 (mm)) / 100) x 100 (%) is 20% or more and 40% or less, and the weight of the tissue paper storage box packaging is 1150 g or more and 1500 g or less. Effect of the Invention

[0010] According to the present disclosure, it is possible to provide a tissue paper storage box packaging body that can prevent deformation of the tissue paper storage box and breakage of the film even when packaging a large-capacity, compact tissue paper storage box that can reduce the occurrence of dropback, ensure the initial removal of the tissue paper, and reduce tearing of the tissue paper when removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, X indicates the longitudinal direction of the tissue paper storage box, Y indicates the lateral direction of the tissue paper storage box, and Z indicates the up-down direction. The direction indicated by the arrow Z indicates the upward direction.

FIG. 3 is a cross-sectional view of the tissue paper storage box. FIG. 4 is an explanatory diagram of the manufacturing process of a tissue paper storage box packaging, where (a) shows the process of packaging multiple tissue paper storage boxes with an exterior film, and (b) shows the process of attaching a handle film. Note that FIGS. 2 and 3 show the state in which the tissue paper is being pulled out from the outlet of the tissue paper storage box. Also, FIG. 3 shows a schematic diagram of the tissue paper.

[0014] [Tissue paper storage box packaging] As shown in Fig. 1, the tissue paper storage box packaging 10 according to the present disclosure is a tissue paper storage box packaging 10 in which a plurality of tissue paper storage boxes 20 (five in this embodiment) are stacked one on top of the other and packaged with an exterior film 30. A portable handle film 40 that functions as a handle when carrying the tissue paper storage box packaging 10 is fixed to the exterior film 30 of the tissue paper storage box packaging 10. In other words, the tissue paper storage box packaging 10 includes a plurality of tissue paper storage boxes 20, the exterior film 30, and the handle film 40. When carrying the tissue paper storage box packaging 10, a worker can carry it by gripping the handle film 40, as shown in Fig. 1.

[0015] (Weight of tissue paper storage box packaging) The weight of the tissue paper storage box packaging 10 is 1150g or more and 1500g or less. If the weight of the tissue paper storage box packaging 10 is lower than 1150g, it is difficult to secure the number of sets of tissue paper 21 (see Figures 2 and 3), and it is difficult to obtain a large-capacity tissue paper storage box 20. On the other hand, if the weight of the tissue paper storage box packaging 10 is heavier than 1500g, when the handle film 40 is grasped and carried (hereinafter simply referred to as "when carrying the tissue paper storage box packaging 10"), deformation of the top tissue paper storage box 20 located at the height position where the handle film 40 is attached (hereinafter simply referred to as "deformation of the tissue paper storage box 20") may occur. In addition, when carrying the tissue paper storage box packaging 10, at least one of the handle film 40 and the exterior film 30 (hereinafter simply referred to as "films 30, 40") may break.

[0016] (Tissue paper storage box) As shown in Figures 2 and 3, the tissue paper storage box 20 is a box that stores tissue paper 21 (tissues in this embodiment) inside in a pop-up style and can be taken out. The tissue paper storage box 20 is a box having a top surface 20a having an outlet 22 for the tissue paper 21, a bottom surface 20b facing the top surface 20a, and four side surfaces 20c, 20d, 20e, and 20f that connect the top surface 20a and the bottom surface 20b. The tissue paper storage box 20 is formed into a box shape by folding the flaps (not shown) of the top surface 20a, the bottom surface 20b, and the four side surfaces 20c, 20d, 20e, and 20f from a single sheet of cardboard material called a carton blank, and bonding the abutting portions of the flaps with a hot melt adhesive or the like. The bottom surface 20b does not have a structure that pushes the tissue paper 21 upward when the tissue paper 21 inside becomes low. The tissue paper storage boxes 20 are stacked so that their bottom surfaces 20b face the top surfaces 20a of the other tissue paper storage boxes 20. The five tissue paper storage boxes 20 of the tissue paper storage box package 10 are stacked in a row one above the other, with the top surfaces 20a on top and the bottom surfaces 20b on the bottom, and are wrapped in an exterior film 30.

[0017] In the following description, the longitudinal direction of the top surface 20a through which the outlet 22 extends is referred to as the "X direction," and the transverse direction (width direction) perpendicular to the longitudinal direction of the top surface 20a is referred to as the "Y direction." In addition, the direction in which multiple tissue paper storage boxes 20 are stacked is referred to as the up-down direction.

[0018] (Gram weight of tissue paper storage box) The basis weight of the tissue paper storage box 20 is the basis weight of the paperboard material called carton blanks that constitutes the tissue paper storage box 20, and is 300 g / m 2 More than 400g / m 2 The basis weight of the tissue paper storage box 20 is 300 g / m 2 If the thickness is lower than 400 g / m, the tissue paper storage box 20 may be deformed when the tissue paper storage box package 10 is carried. 2 If the thickness is higher than 310 g / m, the weight of the tissue paper storage box package 10 increases, and there is a possibility that the films 30, 40 may break when the tissue paper storage box package 10 is carried. 2 More preferably, the upper limit of the above range of the basis weight of the tissue paper storage box 20 is 350 g / m 2 It is more preferable that:

[0019] (Storage box dimensions) The length LC of the tissue paper storage box 20 in the X direction (longitudinal direction) is preferably 200 mm or more and 260 mm or less, more preferably 210 mm or more and 250 mm or less, and even more preferably 220 mm or more and 240 mm or less. The length WC of the tissue paper storage box 20 in the Y direction (transverse direction) is preferably 90 mm or more and 130 mm or less, more preferably 95 mm or more and 125 mm or less, and even more preferably 100 mm or more and 120 mm or less.

[0020] Moreover, the height HC (length in the Z direction) of the tissue paper storage box 20 is preferably 60 mm or more and 74 mm or less. If the height HC of the tissue paper storage box 20 is set lower than 60 mm, the initial removal of the tissue paper 21 is reduced. On the other hand, if the height HC of the tissue paper storage box 20 is set higher than 74 mm, the tissue paper 21 becomes difficult to pick up and the drop-back phenomenon is more likely to occur.

[0021] (tissue paper) The tissue paper 21 is stored in a stacked state in the internal space of the tissue paper storage box 20 so that it can be removed in a pop-up style from the outlet 22 on the top surface 20a of the tissue paper storage box 20. The tissue paper 21 is preferably a set of two-ply tissue, and is preferably prevented from peeling by knurling (crimper, edge embossing) processing or the like. The tissue paper 21 of this embodiment is a set of two-ply tissue that is folded alternately in a pop-up style by a multi-stand interfolder type processing machine, and the direction (pulling direction) of the tissue paper 21 removed from the outlet 22 of the tissue paper storage box 20 is the CD (Cross Direction). The CD direction is perpendicular to the MD (Machine Direction) direction of the tissue paper 21.

[0022] When processing the tissue paper 21, first, two plies (two sheets) of raw sheet (not shown) are overlapped to form a sheet having a predetermined basis weight and thickness. Next, the obtained sheet is knurled, and then the sheets are folded and stacked so that they overlap each other using a multi-stand interfolder (processing machine). The stacked sheets are then compressed and cut to a predetermined size to form a stack (sometimes called a "clip"). The stack of tissue paper 21 obtained in this way is filled into a paper tissue paper storage box 20 (sometimes called a "carton").

[0023] In this way, when the tissue paper 21 is processed using the multi-stand type interfolder, the direction in which the tissue paper 21 stored in the tissue paper storage box 20 is pulled out is the CD direction. As shown in Figure 3, the tissue paper 21 in the tissue paper storage box 20 is folded in a V-shape in cross section when viewed from the short side direction of the tissue paper storage box 20, and is stored in a pop-up style so that it can be removed.

[0024] (Number of pairs) The number of sets of tissue paper 21 stored in the tissue paper storage box 20 is between 230 and 300. If the number of sets of tissue paper 21 is less than 230, a large-capacity tissue paper storage box 20 cannot be obtained, and the drop-back phenomenon is likely to occur. On the other hand, if the number of sets of tissue paper 21 is more than 300, the tissue paper 21 is likely to tear when removed.

[0025] (Dimensions of sanitary tissue paper) The length of the thin paper 21 in the pull-out direction (CD direction) is preferably 150 mm or more and 240 mm or less. If the length of the thin paper 21 in the pull-out direction is shorter than 150 mm, the drop-back phenomenon is more likely to occur. On the other hand, if the length of the thin paper 21 in the pull-out direction is longer than 240 mm, the volume of the clips increases when stacked, making it difficult to obtain a compact thin paper storage box 20. It is more preferable that the lower limit of the above range of the length of the thin paper 21 in the pull-out direction is 180 mm or more. It is more preferable that the upper limit of the above range of the length of the thin paper 21 in the pull-out direction is 210 mm or less.

[0026] The length of the thin paper 21 in the direction intersecting (perpendicular) to the unwinding direction (MD direction) is preferably 155 mm or more and 245 mm or less. If the length of the thin paper 21 in the direction intersecting the unwinding direction is shorter than 155 mm, the drop back phenomenon is more likely to occur. On the other hand, if the length of the thin paper 21 in the direction intersecting the unwinding direction is longer than 240 mm, the thin paper 21 will be more likely to get caught in the slit of the outlet 22 when unwinding, making it difficult to unwind. It is more preferable that the lower limit of the above range of the length of the thin paper 21 in the direction intersecting the unwinding direction is 200 mm or more.

[0027] (Relationship between the length of tissue paper and the height of the tissue paper storage box) The value represented by the following formula (1) is equal to or greater than 0.6 and equal to or less than 0.75. (Height HC of tissue paper storage box 20 (mm)) / (Length of tissue paper 21 in the pull-out direction (mm) / 2) (1) If the value represented by the above formula (1) is set lower than 0.6, the height HC of the tissue paper storage box 20 becomes too short relative to the half length of the tissue paper 21 in the pull-out direction, so that the drop-back phenomenon can be suppressed, but the initial take-out property of the tissue paper 21 decreases, and the tissue paper 21 may be torn or two sheets may be taken out in succession. On the other hand, if the value represented by the above formula (1) is set higher than 0.75, the height HC of the tissue paper storage box 20 becomes too long relative to the half length of the tissue paper 21 in the pull-out direction, so that the drop-back phenomenon is likely to occur as the tissue paper 21 decreases. From the viewpoint of achieving both drop-back prevention and take-out property, it is more preferable that the lower limit of the above range of the value represented by the above formula (1) is 0.60 or more, and it is more preferable that the upper limit of the above range is 0.63 or less.

[0028] (Tensile strength of tissue paper DCDT) The tensile strength DCDT (Dry Cross Direction Tensile strength) in the pulling direction (CD direction) of the thin paper 21 when dry is 100 gf / 25 mm or more and 200 gf / 25 mm or less to ensure a suitable feel and texture. If the tensile strength DCDT of the thin paper 21 is lower than 100 gf / 25 mm, the strength in the pulling direction becomes too low, and the thin paper 21 becomes easily torn when the thin paper 21 is removed. On the other hand, if the tensile strength DCDT of the thin paper 21 is greater than 200 gf / 25 mm, the thin paper 21 becomes too hard and has a poor feel to the touch.

[0029] (Measurement of tensile strength) The tensile strength DCDT of the tissue paper 21 is measured based on JIS P 8113. However, the test piece is a 25 mm wide tissue paper 21 (2 ply), the pulling speed is 300 mm / min, the distance between the gripping tools is 100 mm, and the test piece is kept in equilibrium under the temperature and humidity conditions specified in JIS P 8111 (23±1°C, 50±2% RH) and then measured.

[0030] (paper thickness) The thickness per 10 plies of the tissue paper 21 (hereinafter simply referred to as the "thickness of the tissue paper 21") is preferably 0.38 mm / 10 ply or more and 0.75 mm / 10 ply or less. If the thickness of the tissue paper 21 is thinner than 0.38 mm / 10 ply, the strength will be too low and the tissue paper 21 will be easily torn when the tissue paper 21 is removed. On the other hand, if the thickness of the tissue paper 21 is thicker than 0.75 mm / 10 ply, the height of the clip will be too high when a large capacity is used, making it difficult to obtain a compact tissue paper storage box 20.

[0031] The paper thickness is measured using the following method. The device used is a thickness gauge (a dial thickness gauge "PEACOCK" manufactured by Ozaki Manufacturing Co., Ltd.). The measurement conditions are a measurement load of 3.7 kPa and a gauge head diameter of 30 mm. The sample is placed between the gauge head and the measurement table, and the gauge is read when the gauge head is lowered at a speed of 1 mm per second or less. One measurement is performed with 10 sheets of 1 ply (5 sets of 2 ply sheets) stacked together, and the measurement is repeated 10 times to average the measurement results.

[0032] (Basic weight) The basis weight of one ply of the thin paper 21 (hereinafter simply referred to as the "basis weight of the thin paper 21") is 9 g / m 2 More than 15g / m 2 The basis weight of the thin paper 21 is preferably 9 g / m or less. 2 If the basis weight of the thin paper 21 is smaller than 15 g / m, the thin paper 21 is easily torn when the thin paper 21 is taken out. 2 If it is greater than this, the feel is poor. Basis weight is measured according to JIS P 8124.

[0033] (Exterior film) 1 and 4, the exterior film 30 is a resin film that packages multiple stacked tissue paper storage boxes 20. The exterior film 30 covers the multiple stacked tissue paper storage boxes 20 in all directions (both sides in the X direction, both sides in the Y direction, and both sides in the Z direction).

[0034] Examples of resin films used for the exterior film 30 include LDPE (low density polyethylene), LLDPE (linear low density polyethylene), HDPE (high density polyethylene), CPP (unoriented polypropylene), and films obtained by blending or mixing these materials. Also, these films may be laminated, coated, or multi-layered with different materials. Examples of the different materials include OPP (oriented polypropylene), EVOH (ethylene vinyl alcohol copolymer), Ny (nylon), PET (polyethylene terephthalate), and PVDC (polyvinylidene chloride).

[0035] (Handle film) The handle film 40 is a resin film that functions as a handle to be held when carrying the tissue paper storage box package 10.

[0036] Examples of resin films used for the handle film 40 include LDPE (low density polyethylene), LLDPE (linear low density polyethylene), HDPE (high density polyethylene), CPP (unoriented polypropylene), and films obtained by blending or mixing these materials. Also, these films may be laminated, coated, or multi-layered with different materials. Examples of the different materials include OPP (oriented polypropylene), EVOH (ethylene vinyl alcohol copolymer), Ny (nylon), PET (polyethylene terephthalate), and PVDC (polyvinylidene chloride).

[0037] The handle film 40 extends long in the X direction (the longitudinal direction of the tissue paper storage box 20), and both ends 40b in the X direction are fixed to the exterior film 30 on the side. The middle part 40a in the X direction of the handle film 40 extends in the X direction along the exterior film 30 covering the top surface 20a of the tissue paper storage box 20A located at the top of the multiple tissue paper storage boxes 20, and is not fixed to the exterior film 30. The both ends 40b of the handle film 40 bend downward from both ends of the middle part 40a in the X direction, extend along the exterior film 30 on the side, and are welded (fixed) to the exterior film 30 by heat sealing. In this embodiment, the both ends 40b of the handle film 40 are welded by heat sealing to the exterior film 30 covering the side parts 20e, 20f of the tissue paper storage box 20A located at the top of the multiple tissue paper storage boxes 20. When gripping the handle film 40, the middle portion 40a of the handle film 40 is gripped.

[0038] (Handle film thickness) The thickness of the handle film 40 is 50 μm or more and 60 μm or less. If the thickness of the handle film 40 is thinner than 50 μm, the handle film 40 may break when the thin paper storage box package 10 is carried. On the other hand, if the thickness of the handle film 40 is thicker than 60 μm, the load is concentrated on the welded exterior film 30, and the exterior film 30 may easily break. In addition, since the rigidity of the handle film 40 is high, deformation of the thin paper storage box 20 may occur. In addition, the lower limit of the above range of the thickness of the handle film 40 is more preferably 52 μm or more. In addition, the upper limit of the above range of the thickness of the handle film 40 is more preferably 56 μm or less. The thickness of the handle film 40 is measured in accordance with JIS K 7130.

[0039] (Handle film width) The width of the handle film 40 (length in the Y direction) is 40 mm or more and 60 mm or less. If the width of the handle film 40 is shorter than 40 mm, there is a possibility that the handle film 40 may break when the tissue paper storage box package 10 is carried. On the other hand, if the width of the handle film 40 is longer than 60 mm, it becomes difficult to hold as it is wider than the fingers of the hand, and the amount of film used increases. The width of the handle film 40 is preferably 50 mm.

[0040] (Handle film stretch) When a load of 3 kg is applied in the length direction (direction crossing the width direction) to a handle film 40 having a width of 50 mm and a length (direction crossing the width direction) of 100 mm, the value represented by the following formula (2) is greater than or equal to 20% and less than or equal to 40%. ((Length of handle film 40 at 3 kg load (mm) - 100 (mm)) / 100) x 100 (%)...(2) If the value represented by the above formula (2) is lower than 20%, the strength of the handle film 40 is too strong, and when the tissue paper storage box package 10 is carried, the uppermost tissue paper storage box 20A may be deformed, or the heat seal portion between both ends 40b of the handle film 40 and the exterior film 30 may break. On the other hand, if the value represented by the above formula (2) is higher than 40%, the strength of the handle film 40 is too low, and the handle film 40 may stretch and break when the tissue paper storage box package 10 is carried. In addition, it is more preferable that the lower limit of the above range of the value represented by the above formula (2) is 25% or more. In addition, it is more preferable that the upper limit of the above range of the value represented by the above formula (2) is 30% or less.

[0041] The length of the handle film 40 when loaded with 3 kg is measured, for example, using a Tensilon universal testing machine (e.g., A&D Co., Ltd.'s STB-1225S benchtop material testing machine). Specifically, a handle film 40 with a width of 50 mm is prepared as a sample, the distance between the upper and lower chucks of the Tensilon universal testing machine is set to 100 mm, and the sample is set in the upper and lower chucks. When setting the sample in the upper and lower chucks, the sample is set so that it extends in the length direction between the upper and lower chucks. Then, the sample is pulled at a speed of 300 mm / min, and the distance between the chucks when the load applied to the sample becomes 3 kg is measured as the length of the handle film 40 when loaded with 3 kg. In the above formula (2), the original length (100 mm) is subtracted from the measured length of the handle film 40 when loaded with 3 kg to determine the elongation of the handle film 40 when loaded with 3 kg, and the determined elongation of the handle film 40 when loaded with 3 kg is divided by the original length (100 mm) and then multiplied by 100 to convert the unit into %.

[0042] (Manufacturing process for tissue paper storage box packaging) Next, the manufacturing process of the tissue paper storage box package 10 will be described with reference to Fig. 4. In Fig. 4, the dashed line A indicates the MD direction of the exterior film 30, the dashed line B indicates the TD (Transverse Direction) direction of the exterior film 30, the two-dot dash line C indicates the TD direction of the handle film 40, and the two-dot dash line D indicates the MD direction of the handle film 40.

[0043] When manufacturing the tissue paper storage box packaging 10, first, a tissue paper storage box 20 product containing tissue paper 21 is manufactured, and then multiple (e.g., five) manufactured tissue paper storage boxes 20 are stacked on top of each other.

[0044] Next, as shown in Fig. 4(a), the exterior film 30 is tightly wrapped around the multiple tissue paper storage boxes 20 to surround the four side portions 20c, 20d, 20e, and 20f of the multiple tissue paper storage boxes 20 stacked on top of each other, forming a cylindrical shape. At this time, the exterior film 30 is wrapped so that the MD direction of the exterior film 30 is the circumferential direction surrounding the four side portions 20c, 20d, 20e, and 20f of the multiple tissue paper storage boxes 20, and the TD direction of the exterior film 30 is the up-down direction of the multiple tissue paper storage boxes 20. With the exterior film 30 tightly wrapped around the multiple tissue paper storage boxes 20, both ends of the exterior film 30 in the MD direction are welded together by heat sealing.

[0045] Next, as shown in Fig. 4(b), both sides in the TD direction of the exterior film 30 protruding from both the top and bottom of the multiple tissue paper storage boxes 20 are folded at positions along the top surface part 20a located at the uppermost side of the multiple tissue paper storage boxes 20 and the bottom surface part 20b located at the lowermost side, and are welded by heat sealing. Specifically, of the exterior film 30 protruding from both the top and bottom of the multiple tissue paper storage boxes 20, two opposing flap-shaped sides are folded toward each other, and then another two opposing flap-shaped sides are folded toward each other in the same manner, and these folded parts are sealed by heat fusion or the like. In other words, the multiple tissue paper storage boxes 20 stacked on top of each other are caramel-wrapped with the exterior film 30.

[0046] Next, as shown in FIG. 4(b), with the middle portion 40a of the handle film 40 aligned with the top surface 20a of the uppermost tissue paper storage box 20A, both sides of the handle film 40 in the X direction are folded downward, and both ends 40b of the handle film 40 are heat-sealed to the exterior film 30 on the side.

[0047] Although the present invention has been described based on the above embodiment, the present invention is not limited to the contents of the above embodiment, and can be modified as appropriate without departing from the scope of the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on this embodiment are naturally included in the scope of the present invention.

[0048] The present invention will be described below with reference to examples, but the present invention is not limited to these examples in any way.

[0049] Tissue storage box packages of Examples 1 to 8 and Comparative Examples 1 to 15 were created under the conditions shown in Tables 1 to 3. 2-ply (two layers per set) tissue was stored as the thin paper in the tissue storage box packages of Examples 1 to 8 and Comparative Examples 1 to 15. The tissue storage box packages of Examples 1 to 8 and Comparative Examples 1 to 15 have the same tissue basis weight, thickness (paper thickness), and sheet tensile strengths DMDT and DCDT.

[0050] The tissue paper storage box packages of Examples 1 to 8 and Comparative Examples 1 to 15 were subjected to the following three evaluations (evaluation of "drop back", evaluation of "top box deformation", and evaluation by "handle swing test").

[0051] (Drop Back) The "drop back" evaluation was an evaluation of the occurrence of the drop back phenomenon, in which 50 panelists were asked to use one tissue paper storage box, the average number of times the box dropped back, and an evaluation was made according to the following criteria. ○: Drop back occurred in 1 or less people ×: Drop back occurred to 2 or more people

[0052] (Top box transformation) The "top box deformation" evaluation was performed on the deformation of the topmost tissue paper storage box (sometimes called the "top box") among multiple tissue paper storage boxes. The tissue paper storage box package was lifted by grasping the handle film, and then the box was allowed to drop 30 cm while still grasping the handle film, and stopped in the air. This was repeated 10 times to check whether the top surface of the top box was deformed, and evaluation was performed according to the following criteria. ◯: The fold line on the short side of the top surface of the top box was not deformed. ×: The fold line on the short side of the top surface of the top box was deformed, and the top surface or the short side was broken.

[0053] (Handle swing test) The evaluation by the "handle swing test" is based on the results of the handle swing test. In the handle swing test, the tissue paper storage box package is lifted by grasping the handle film, and then, while still grasping the handle film, it is allowed to naturally drop 30 cm and stopped in mid-air. This is repeated and the number of times is counted until the welded part between the handle film and the exterior film breaks or until the handle film itself breaks. Evaluation was then performed according to the following criteria. ○: The number of times until the handle film etc. breaks is 30 or more ×: The number of times until the handle film etc. breaks is 29 or less

[0054] The results obtained are shown in Tables 1 to 3.

[0055] [Table 1]

[0056] [Table 2]

[0057] [Table 3]

[0058] As shown in Tables 2 and 3, in Comparative Examples 1 to 3, 6, 7, and 10 to 12, the number of sets was less than 230 sets, and they cannot be considered tissue paper storage boxes that store a large amount of tissue paper.In addition, the other Comparative Examples received low ratings in each of the above evaluations.

[0059] As shown in Table 1, it has been confirmed that the present disclosure can provide a tissue paper storage box packaging body that can prevent deformation of the tissue paper storage box and breakage of the film even when packaging a large-capacity, compact tissue paper storage box that can reduce the occurrence of dropback, ensure the initial removal of the tissue paper, and reduce tearing of the tissue paper when removed.
