Summary of the Invention

Problems to be Solved by the Invention

[0004] The container circulates in the sales process while housing a plurality of absorbent articles, and is further carried by the user. The container is subject to external forces during the process of being taken in and out during transportation, being displayed during sales, or being carried after purchase. The external forces received by the container vary depending on the handling method. When a large external force is applied to the container, an external force is also applied to the absorbent articles inside the container, and the absorbent articles may be deformed before use. If the absorbent articles are deformed before use, problems such as leakage may occur due to the absorbent articles being wrinkled during wearing, or a sense of discomfort may occur during wearing.

[0005] This invention has been made in view of the above problems, and aims to provide a container for absorbent articles that can suppress deformation of absorbent articles contained within the container. [Means for solving the problem]

[0006] An absorbent article container holds an absorbent article having an absorbent core, enclosed by a container sheet. The container has a joint that joins the outer surfaces of the folded container sheet when the container sheet is folded inward in a valley fold in a first direction. The joint has a first joint and a second joint located further outward in the first direction than the first joint. The joint strength of the second joint is lower than that of the first joint. [Brief explanation of the drawing]

[0007] [Figure 1] Figure 1 is a perspective view of a container for an absorbent article according to an embodiment. [Figure 2] Figure 2 shows the containment sheet that makes up the container for the absorbent article. [Figure 3] Figure 3 is a plan view of the folded surface of the storage sheet in its unfolded state. [Figure 4] Figure 4 is a schematic diagram showing a cross-section of the container for the absorbent article according to the first embodiment. [Figure 5] Figure 5 is a schematic diagram showing a cross-section of a container for absorbent articles of a different form. [Modes for carrying out the invention]

[0008] (1) Outline of the Embodiment The following matters become clear from this specification and the accompanying drawings: The absorbent article housing according to Embodiment 1 houses an absorbent article having an absorbent core, which is housed in a housing sheet. The housing has a joint that joins the outer surfaces of the housing sheet when it is folded in a valley fold toward the inside in a first direction. The joint has a first joint and a second joint located further outward in the first direction than the first joint. The joint strength of the second joint is lower than that of the first joint. According to this embodiment, because the joint strength of the second joint is lower than that of the first joint, the joint of the second joint is easily released. When an external force is applied to the housing, the release of the joint of the second joint absorbs the deformation of the housing and suppresses the deformation of the absorbent article inside.

[0009] In a preferred embodiment, the invention according to Embodiment 2 may have the following features in the invention according to Embodiment 1. The containment sheet has an ink-present region on the outer surface of the containment sheet where ink is disposed, and an ink-non-present region on the outer surface of the containment sheet where no ink is disposed. The first joint joins the ink-non-present regions together. At least a part of the second joint joins the ink-present regions. The first joint joins the ink-non-present regions together, so ink dissolution does not occur, and it is easy to ensure joint strength. On the other hand, at least a part of the second joint causes ink dissolution, making it difficult to ensure joint strength. Therefore, the joint strength of the second joint can be lower than that of the first joint. The second joint is located further out in the first direction than the first joint and is easily visible to the user. Since at least a part of the second joint joins the ink-present regions, the aesthetic appearance of the area visible to the user can be enhanced by printing.

[0010] In a preferred embodiment, the invention according to Embodiment 3 may have the following features in the invention according to Embodiment 2: The second joint joins the ink-containing regions together. This embodiment also makes it possible to lower the bonding strength of the second joint to that of the first joint. Furthermore, since the first joint joins the ink-free regions together and the second joint joins the ink-containing regions together, it is easy to create a difference in bonding strength between the first and second joints.

[0011] In a preferred embodiment, the invention according to Embodiment 4 may have the following features in the invention according to Embodiment 2: The second joint joins the ink-containing regions. This embodiment also allows the joint strength of the second joint to be lower than that of the first joint. Furthermore, one surface of a pair of opposing surfaces may have a continuous area where no ink is present, while the other surface may have both an area where no ink is present and an area where ink is present. Surfaces with a continuous area where no ink is present do not experience ink dissolution, thus improving their aesthetic appearance.

[0012] In a preferred embodiment, the invention according to embodiment 5 may have the following features in the invention according to embodiment 1 or 2: The second joint comprises a second inner joint and a second outer joint located outside the second inner joint in the first direction. The joint strength of the second outer joint is lower than that of the second inner joint. According to this embodiment, because the joint strength of the second outer joint is lower than that of the second inner joint, when an external force is applied to the container, the joint of the second outer joint is released, absorbing the deformation of the container and suppressing the deformation of the absorbent article inside.

[0013] In a preferred embodiment, the invention according to embodiment 6 may have the following features in the invention according to embodiment 5: The second internal joint joins the ink-present region and the ink-non-present region. The second external joint joins the ink-present regions together. The second internal joint joins the ink-non-present region and the ink-present region, resulting in less ink dissolution than the second external joint and making it easier to ensure joint strength. On the other hand, the second external joint results in more ink dissolution than the second internal joint, allowing for lower joint strength. The second external joint is located further out in the first direction than the second internal joint and is more easily visible to the user. Since at least a portion of the second external joint joins the ink-present region, the aesthetic appearance of the user-visible area can be enhanced by printing.

[0014] In a preferred embodiment, the invention according to Embodiment 7 may have the following features in the invention according to Embodiment 5. The second inner joint and the second outer joint join the ink-present region and the ink-non-present region. The ink area ratio, which is the area ratio of the ink-present region per unit area of ​​the second outer joint, is higher than the ink area ratio of the second inner joint. According to this embodiment, the second inner joint experiences less ink dissolution than the second outer joint, making it easier to ensure joint strength. On the other hand, the second outer joint is located further out in the first direction than the second inner joint and is more easily visible to the user. Because the area ratio of the ink-present region of the second outer joint is high, the aesthetic appearance of the area visible to the user can be enhanced by printing.

[0015] In a preferred embodiment, the invention according to Embodiment 8 may have the following features in the invention according to Embodiment 1. The containment sheet has an ink-present region on its outer surface where ink is disposed, and an ink-non-existent region on its outer surface where ink is not disposed. The first joint joins the ink-non-existent region and the ink-present region, and the second joint joins the ink-present region. In this embodiment as well, the joint strength of the second joint can be made lower than that of the first joint. Furthermore, since an ink-non-existent region is not provided on one of the pair of opposing surfaces, the aesthetic appearance of the containment can be further improved by the design of the ink-present region, etc.

[0016] In a preferred embodiment, the invention according to embodiment 9 may have the following features in the invention according to any of embodiments 1 to 8: The joint area ratio, which is the area of ​​the joint portion per unit area of ​​the second joint, is smaller than the joint area ratio of the first joint. This embodiment also makes it possible to lower the joint strength of the second joint to that of the first joint. The second joint is located further out in the first direction than the first joint and is more easily visible to the user. Because the joint area ratio of the second joint is small, warping and melting of the sheet due to deformation during joining can be suppressed, and the aesthetic appearance can be maintained.

[0017] According to a preferred embodiment, the invention according to aspect 10 may have the following features in the invention according to any one of aspects 1 to 9. The bending rigidity of the region where the second joining portion is provided is lower than the bending rigidity of the region where the first joining portion is provided. If the bending rigidity of the region where the second joining portion is provided is high, when a force is received from the outside in the first direction of the container, the region where the second joining portion is provided deforms and does not absorb the force, and there is a risk that the force is transmitted to the inside of the container and the absorbent article is deformed. However, since the bending rigidity of the second joining portion is low, the region where the second joining portion is provided deforms to absorb the external force, and deformation of the internal absorbent article can be suppressed.

[0018] According to a preferred embodiment, the invention according to aspect 11 may have the following features in the invention according to any one of aspects 1 to 10. The housing sheet has a vertex located inside in the first direction of the valley fold portion and a pair of opposing surfaces extending outward in the first direction from the vertex. The first joining portion and the second joining portion join the opposing surfaces to each other. The second joining portion is provided at a distance from the outer end in the first direction of the opposing surface. According to this embodiment, when an external force is applied to the outer end in the first direction of the opposing surface, the non-joining region between the second joining portion and the outer end in the first direction of the opposing surface becomes a buffer region, and the force applied to the second joining portion can be reduced.

[0019] In a preferred embodiment, the invention according to embodiment 12 may have the following features in the invention according to any of embodiments 1 to 11. The storage sheet has a vertex located on the inside in the first direction of the valley fold portion, and a pair of opposing surfaces extending outward from the vertex in the first direction. The first joint and the second joint join the opposing surfaces together. The storage sheet has perforations formed thereon extending from the outer end of the opposing surface in the first direction toward the inside in the first direction. The perforations and the second joint are spaced apart in a second direction perpendicular to the first direction. According to this embodiment, when a user carries the storage unit, they may place their fingers or the like near the second joint. At this time, because the perforations and the second joint are spaced apart in the second direction, the force applied to the perforations can be reduced, and the problem of the perforations unintentionally opening can be suppressed.

[0020] In a preferred embodiment, the invention according to embodiment 13 may have the following features in the invention according to any of embodiments 1 to 12. The storage sheet has a vertex located on the inside in the first direction of the valley fold portion, and a pair of opposing surfaces extending outward from the vertex in the first direction. The pair of opposing surfaces have a first opposing surface and a second opposing surface that face each other. The bending stiffness of the outer end of the first opposing surface in the first direction is higher than the bending stiffness of the outer end of the second opposing surface in the first direction. According to this embodiment, because the bending stiffness of the outer end of the first opposing surface in the first direction is relatively high, the portion where the first opposing surface and the second opposing surface join is tilted towards the second opposing surface. Therefore, it becomes difficult for force to be applied equally to both the first opposing surface and the second opposing surface, and the force can be distributed. Thus, deformation that causes the first opposing surface and the second opposing surface to separate from each other can be suppressed.

[0021] According to a preferred embodiment, the invention according to Embodiment 14 may have the following features in the invention according to any one of Embodiments 1 to 13. The storage sheet has a vertex located inside the valley-folded portion in the first direction, and a pair of opposing surfaces respectively extending outward in the first direction from the vertex. The pair of opposing surfaces has a first opposing surface and a second opposing surface facing each other. The storage sheet has an ink presence region where ink is disposed on the outer surface of the storage sheet, and an ink absence region where no ink is disposed on the outer surface of the storage sheet. The ink absence region is provided at the outer end in the first direction of the first opposing surface. The ink presence region is provided at the outer end in the first direction of the second opposing surface. According to this embodiment, it is easy to grasp the boundary between the first opposing surface and the second opposing surface and the position of the joint portion by the difference between the ink presence region and the ink absence region.

[0022] According to a preferred embodiment, the invention according to Embodiment 15 may have the following features in the invention according to any one of Embodiments 1 to 14. The storage sheet has a vertex located inside the valley-folded portion in the first direction, and a pair of opposing surfaces respectively extending outward in the first direction from the vertex. The pair of opposing surfaces has a first opposing surface and a second opposing surface facing each other. In the first direction, the outer edge of the first opposing surface is located outside the outer edge of the second opposing surface. According to this embodiment, when an external force is applied to the outer end in the first direction of the container, the portion where the first opposing surface protrudes more than the second opposing surface becomes a buffer region, and the force applied to the second joint portion can be reduced. Therefore, unintended separation of the second joint portion can be suppressed, the absorbent article can be protected, and the aesthetic appearance of the container can be maintained.

[0023] In a preferred embodiment, the invention according to embodiment 16 may have the following features in the invention according to any of embodiments 1 to 15. The housing has an upper surface and a lower surface that face each other. The joint has an upper joint provided on the upper surface and a lower joint provided on the lower surface. The first joint of the upper joint and the first joint of the lower joint are provided spaced apart in the first direction. The distance in the first direction between the first joints in the upper joint is different from the distance in the first direction between the first joints in the lower joint. According to this embodiment, the region between the first joints does not have a first joint and has low rigidity, making it prone to becoming a buffer region. Furthermore, the region between the first joints includes a region between the vertices of the valley fold portion, which has fewer sheets than the valley fold portion, and functions as a buffer region. Because the length of the buffer region in the first direction differs between the top and bottom surfaces, when a force is applied from the outside in the first direction of the containment, both the top and bottom surfaces do not deform in the same way, and the deformation of one side can suppress the deformation of the other side.

[0024] In a preferred embodiment, the invention according to embodiment 17 may have the following features in the invention according to any of embodiments 1 to 16. The housing has an upper surface and a lower surface that face each other. The joint has an upper joint provided on the upper surface and a lower joint provided on the lower surface. The area of ​​the first joint on the upper joint is larger than the area of ​​the first joint on the lower joint. When a user grasps the housing, it is easier to hold the upper surface than the lower surface. Because the area of ​​the first joint on the upper surface is relatively large, it is easy to maintain the joined state of the first joint even when an external force is applied to the upper surface. On the other hand, the lower surface is the bottom surface when the housing is placed, and if the area of ​​the first joint is too large, the rigidity may be locally high only at the location of the first joint, and the housing may not be able to be placed stably. However, because the area of ​​the first joint on the lower surface is relatively small, the housing can be placed stably.

[0025] In a preferred embodiment, the invention according to embodiment 18 may have the following features in the invention according to any of embodiments 1 to 17. The containment sheet has a base layer having a thermoplastic resin and an ink layer on which ink is applied on the outer surface of the base layer. The melting point of the ink is higher than the melting point of the base layer. According to this embodiment, when the base layer is welded at a temperature at which it melts, the ink is less likely to melt, discoloration of the ink can be suppressed, and the aesthetic appearance can be maintained.

[0026] (2) Composition of the container for absorbent articles The absorbent article container 1 (hereinafter referred to as "container 1") according to the embodiment will be described below with reference to the drawings. In the following drawings, identical or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of each dimension may differ from those of reality. Therefore, specific dimensions should be determined by referring to the following explanation. In addition, there may be parts where the relationships and ratios of dimensions differ between drawings.

[0027] Figure 1 is a perspective view of a container 1 according to an embodiment. The container 1 contains absorbent articles 20 by a storage sheet 10. The container 1 has a storage space 5 inside which absorbent articles 20 are contained, formed by folding the storage sheet 10 and joining the storage sheet 10 via a joint. The absorbent articles 20 are contained in the storage space 5. There may be one or more absorbent articles contained in the storage space 5. Examples of absorbent articles 20 include disposable diapers, sanitary napkins, incontinence pads, and panty liners. The absorbent articles 20 may be stacked in the thickness direction within the container 1. The absorbent articles 20 may be contained in the storage space 5 in the state of articles to be used at the time of use (sanitary napkins, disposable diapers), or they may be contained in the storage space 5 in the state of being individually packaged by individual packaging sheets (not shown).

[0028] The storage unit 1 has three mutually orthogonal directions: a first direction D1, a second direction D2, and a third direction D3. The first direction is the direction in which the storage sheet 10 is folded in a valley fold, and the storage sheet 10 is folded in a valley fold toward the inside of the first direction D1. The second direction D2 is the direction in which the perforations 18 (described later) and the joints are separated, and the perforations 18 and the joints are separated in the second direction D2. In the upright state of the storage unit 1 shown in Figure 1, the first direction D1 is the horizontal direction extending left and right, the second direction D2 is the depth direction, and the third direction D3 is the up and down direction. The upright state is a state in which the storage unit 1 is positioned so that the up and down directions of the characters 15 and design 16 shown on the storage unit 1 match the up and down directions in the upright state, and the surface corresponding to the front of the arrangement of characters etc. on the storage unit 1 is positioned facing forward. Furthermore, in other forms, the first direction may be horizontal, the second direction may be vertical, and the third direction may be depth; or the first direction may be depth, the second direction may be horizontal, and the third direction may be vertical; or the first direction may be depth, the second direction may be vertical, and the third direction may be horizontal; or the first direction may be vertical, the second direction may be depth, and the third direction may be horizontal; or the first direction may be vertical, the second direction may be horizontal, and the third direction may be horizontal to depth.

[0029] The absorbent article 20 can be any well-known absorbent article 20 as appropriate. However, preferably, an absorbent article 20 with a relatively soft absorbent core can be used. This is because, as described later, the container 1 of this embodiment is configured to suppress local hardening of the absorbent core. Specifically, the absorbent article 20 may have a bending stiffness value of 5.0 to 50.0 mN·m in the longitudinal and width directions in the region including the absorbent core. This bending stiffness is measured, for example, by following the procedure below. (1) Prepare an IMADA torque testing machine, EX-0762, in a constant temperature and humidity chamber (20°C, 65%RH). Set the load cell to 50N for tension and compression, and the torque to 1N. (2) Cut out the sample as shown in Table 1. (3) Attach 50mm x 20mm cloth tape to both ends of the sample in the measurement direction, with the length of the tape perpendicular to the measurement direction, so that the jig spacing is as shown in Table 1, thereby forming gripping parts at both ends of the sample in the measurement direction. (4) Attach the sample to the jig and measure its maximum torque value (mN·m) under the conditions shown in Table 1. (5) The measurement is performed five times with different samples, and the average value is adopted as the bending stiffness value. [Table 1]

[0030] As shown in Figure 1, the container 1 may have a rectangular shape and include a first surface 101 to a sixth surface 106. The first surface 101 to the sixth surface 106 may be rectangular surfaces, and their intersecting boundaries may not intersect perpendicularly but curved. The first surface 101 and the second surface 102 are positioned opposite each other with a gap in the second direction D2, the third surface 103 and the fourth surface 104 are positioned opposite each other with a gap in the first direction D1, and the fifth surface 105 and the sixth surface 106 are positioned opposite each other with a gap in the third direction D3. The first surface 101 and the second surface 102 may have surfaces extending in at least the first direction D1 and the third direction D3. The first surface 101 constitutes the front of the container 1 in the upright state shown in Figure 1, and the second surface 102 constitutes the back. The third surface 103 and the fourth surface 104 may have surfaces extending in at least the second direction D2 and the third direction D3. The third surface 103 and the fourth surface 104 constitute the side surfaces of the container 1 in an upright state. The fifth surface 105 and the sixth surface 106 may have surfaces extending in at least the first direction D1 and the second direction D2. The fifth surface 105 constitutes the "upper surface" of the present invention, and the sixth surface 106 constitutes the "lower surface" of the present invention. The joints of the container sheet 10 may be provided on at least the fifth surface as the upper surface and the sixth surface as the lower surface.

[0031] The container 1 according to this embodiment is configured to suppress deformation of the absorbent article 20 contained within the container 1. Next, the configuration for suppressing deformation of the absorbent article 20 contained within the container 1 will be described in detail. The configuration for suppressing deformation of the absorbent article 20 contained within the container 1 can be broadly classified into four forms. Figure 2 is a schematic diagram showing the folded state of the container sheet 10 before the joint portion of the container sheet 10 is formed. Figure 3 is a plan view of the folded surface 11 of the container sheet 10 in an unfolded state. Note that in Figures 2 and 3, the ink-present and ink-non-present regions, which will be described later, are shown, and the characters 15 and design 16 provided on the container 1 are omitted. Figures 1 to 3 show containers that are commonly applicable to the first to fourth forms. Figure 4(a) is a schematic cross-sectional view of the upper joint portion 95 of the container according to the first form along the first direction D1, and Figure 4(b) is a schematic cross-sectional view of the lower joint portion 96 along the first direction D1. Figure 5 is a partial cross-sectional view of the upper joint 95 in a different embodiment, along the first direction D1.

[0032] The container 1 is formed by a so-called gusset tube bag. The container sheet 10, in the cylindrical state shown in Figure 2, has a pair of foldable surfaces 11 and a pair of non-foldable surfaces 12. The foldable surfaces 11 and non-foldable surfaces 12 are arranged alternately and connected to each other in the cylindrical state. One surface of the foldable surface 11 constitutes the third surface 103, a part of the fifth surface 105 connected to the third surface 103, and a part of the sixth surface 106. The other surface of the foldable surface 11 constitutes the fourth surface 104, a part of the fifth surface 105 connected to the fourth surface 104, and a part of the sixth surface 106. Also, one surface of the non-foldable surface 12 constitutes the first surface 101, a part of the fifth surface 105 connected to the first surface 101, and a part of the sixth surface 106. The other side of the non-folding surface 12 constitutes the second surface 102, a part of the fifth surface 105 which is connected to the second surface 102, and a part of the sixth surface 106.

[0033] The storage sheet 10 is made of a sheet material such as a resin film, and its outer surfaces are joined together by a joint to form a bag shape, as shown in Figure 1. The pair of folded surfaces 11 are valley-folded toward the inside in the first direction D1. That is, the folded surface 11 is the surface in which the valley-fold portion is formed, and the non-folded surface 12 is the surface in which the valley-fold portion is not formed. The joint joins the outer surfaces of the storage sheet 10 that constitute the folded surface 11 when the folded surface 11 is folded in a valley fold. The storage body 1 has an internal joint (not shown) that joins the inner surfaces of the storage sheet 10 when it is folded. The internal joint connects the inner surfaces of the non-folding surfaces 12 in the central region 1C (the region sandwiched by the vertices of the valley folds in the first direction D1) as shown in Figure 4, and connects the inner surface of the folding surface 11 to the inner surface of the non-folding surface 12 in the side region 1S (the region where the valley folds are formed).

[0034] The joint comprises a first joint 80 and a second joint 90 located further outward in the first direction D1 than the first joint 80. The first joint 80 is located on the side of the vertex 53 of the valley fold portion. The joint strength of the second joint 90 is lower than that of the first joint 80. When an external force is applied to the container 1, the container 1 deforms, and the absorbent article 20 inside may deform along with the deformation of the container 1. Since this external force is applied from the outside of the container 1, it is more likely to be applied to the second joint 90, which is located further outward in the first direction D1 than the first joint 80. With this configuration, since the joint strength of the second joint 90 is lower than that of the first joint 80, the joint of the second joint 90 is easily released. When an external force is applied to the container 1, the release of the joint of the second joint 90 absorbs the deformation of the container 1 and suppresses the deformation of the absorbent article inside.

[0035] The joint strength can be measured by the following method: (1) Take a sample measuring 100 mm in length and 15 mm in width, with the joint to be measured in the center. (2) Attach 50 mm x 25 mm aluminum tape to both ends of the length of the sample, with a jig spacing of 50 mm, to form gripping parts at both ends of the sample in the measurement direction. (3) Attach the sample to the jig and measure its maximum torque value at a tensile speed of 500 mm / min. (4) The measurement is performed five times with different samples, and the average value is adopted as the joint strength. The unit is N / 25 mm. The joint strength in the non-jointed area is 0 N / 25 mm.

[0036] The first joint 80 and the second joint 90 may be adjacent to each other or spaced apart in the first direction D1. The first joint 80 and the second joint 90 may have an elongated shape with a longer length in the first direction D1. Furthermore, a configuration in which the joint strength of the first joint 80 and the joint strength of the second joint 90 are different may be due to differences in welding strength (temperature, pressing force) such as heat welding, differences in the bonding area per unit area, or differences in the composition of the materials being joined (the composition of the sheet joined by the first joint and the composition of the sheet joined by the second joint 90).

[0037] As shown in Figures 2 and 3, the storage sheet 10 may have an ink-present region R2 on its outer surface where ink is placed, and an ink-absent region R1 on its outer surface where no ink is placed. In Figures 2 and 3, the ink-present region R2 is the area with hatching, and the ink-absent region R1 is the area shown in white. Note that the ink-present region R2 is the area on the outer surface of the storage sheet 10 where ink is placed, and the ink-absent region R1 is the area on the outer surface of the storage sheet 10 where no ink is placed, and this includes, for example, an area where ink is placed in the inner layer of the storage sheet 10, and a layer other than ink (a laminate layer) is placed on the outer side of that ink layer.

[0038] As shown in Figure 4, in the first embodiment, the first joint 80 may join two ink-free regions R1, and at least a part of the second joint 90 may join two ink-present regions R2. The second joint 90 only needs to join two ink-present regions R2 in at least a part. The second joint 90 in the first embodiment may have a portion that joins two ink-free regions R1 and two ink-present regions R2. The first joint 80 joins two ink-free regions R1, so ink dissolution does not occur, and it is easy to ensure joint strength. On the other hand, the second joint 90 joins two ink-free regions R1 and two ink-present regions R2, so ink dissolution occurs, and it is difficult to ensure joint strength. Therefore, the joint strength of the second joint 90 can be made lower than that of the first joint 80, and deformation of the absorbent article inside can be suppressed. Furthermore, an ink-free region R1 can be continuously provided on one of the pair of opposing surfaces described later, and an ink-free region R1 and an ink-present region R2 can be provided on the other surface. On the surface where the ink-free region R1 is continuously provided, ink dissolution does not occur, and its aesthetic appearance can be improved. The second joint 90 of the first embodiment may have a portion that joins the ink-present regions R2 together. The first joint 80 joins the ink-free regions R1 together, so ink dissolution does not occur, and it is easy to ensure joint strength. On the other hand, the second joint 90 joins the ink-present regions R2 together, so ink dissolution occurs, and it is difficult to ensure joint strength. Therefore, the joint strength of the second joint 90 can be made lower than that of the first joint 80, and deformation of the absorbent article inside can be suppressed. Furthermore, since the first joint 80 joins two ink-free regions R1 and the second joint 90 joins two ink-present regions R2, it is easy to create a difference in bonding strength between the first joint 80 and the second joint 90. In addition, the second joint 90 is located further out in the first direction D1 than the first joint 80, making it more visible to the user. Since at least a portion of the second joint 90 joins the ink-present regions R2, the aesthetic appearance of the user-visible area can be enhanced by printing.

[0039] Furthermore, in the configuration shown in Figure 4, the second joint portion includes both a portion that joins the ink-free region R1 and the ink-present region R2, and a portion that joins the ink-present regions R2 together, but the configuration is not limited to this. As shown in Figure 5(a), the first joint portion 80 may join the ink-free regions R1 together, and the second joint portion 90 may join the ink-present regions R2 together over the entire surface. Alternatively, as shown in Figure 5(b), the first joint portion 80 may join the ink-free regions R1 together, and the second joint portion 90 may join the ink-present region R2 and the ink-free region R1 over the entire surface.

[0040] As shown in Figure 5(c), in the second embodiment, the joint area ratio of the second joint 90, which is the area of ​​the jointed portion per unit area, may be smaller than the joint area ratio of the first joint 80. The joint area ratio per unit area is the ratio of the area of ​​the joined portion to the area surrounding the outer edge (outer edge in the first direction and outer edge in the direction perpendicular to the first direction) of the region where each joint (e.g., the first joint) is located. For example, the joint area ratio of intermittently joined joints is lower than that of joints joined over the entire surface. In the second embodiment as well, the joint strength of the second joint 90 can be lower than that of the first joint 80. In addition, the second joint 90 is located outside the first direction D1 than the first joint 80 and is more easily visible to the user. Because the joint area ratio of the second joint 90 is small, warping and melting of the sheet due to deformation during joining can be suppressed, and the aesthetic appearance can be maintained. In the second embodiment, the first joint 80 and the second joint 90 may both join ink-present regions R2 together, or they may both join ink-non-present regions R1 together. In the embodiment shown in Figure 5(a), both the first joint 80 and the second joint 90 join ink-non-present regions R1 together, the second joint 90 is intermittently arranged in the first direction D1, and the first joint 80 is continuous with the first direction D1. The lengths of the first joint 80 and the second joint 90 in the direction perpendicular to the first direction D1 are the same. Therefore, the joining area ratio of the second joint 90 is lower than that of the first joint 80. Furthermore, the embodiment may have configurations of both the first and second embodiments, that is, the second joint 90 may join ink-present regions R2 together, and the joining area ratio of the first joint 80 may be higher than that of the second joint 90.

[0041] As shown in Figure 5(d), in the third embodiment, both the first joint 80 and the second joint 90 join an ink-free region R1 and an ink-present region R2, and the ink area ratio, which is the area ratio of the ink-present region R2 per unit area of ​​the second joint 90, may be higher than the ink area ratio of the first joint 80. In the third embodiment as well, the bonding strength of the second joint 90 can be lower than that of the first joint 80. The second joint 90 is located outside the first direction D1 compared to the first joint 80 and is more easily visible to the user. Because the ink area ratio of the second joint 90 is high, the aesthetic appearance of the area visible to the user can be enhanced by printing.

[0042] As shown in Figure 5(e), in the fourth embodiment, the first joint 80 may join the ink-free region R1 and the ink-present region R2, and the second joint 90 may join the ink-present regions R2 together. For example, one of the pair of opposing surfaces described later (for example, the first opposing surface 51) may be provided with an ink-present region R2 (without providing an ink-free region R1), and the other surface (for example, the second opposing surface 52) may be provided with both an ink-free region R1 and an ink-present region R2. In the fourth embodiment as well, the joining strength of the second joint 90 can be made lower than that of the first joint 80. Furthermore, by providing only an ink-present region R2 on one of the pair of opposing surfaces (without providing an ink-free region R1), the aesthetic appearance of the container 1 can be further improved by the design of the ink-present region R2. Also, since an ink-free region R1 is not provided on one surface, it becomes easier for the user to distinguish between the first opposing surface 51 and the second opposing surface 52 based on the presence or absence of the ink-free region R1.

[0043] In the first to fourth embodiments, the region inside the first joint 80 in the first direction D1 and outside the vertex 53 in the first direction D1 may consist of two ink-existing regions R2 facing each other, two ink-non-existent regions R1 facing each other, or two ink-existing regions R2 and two ink-non-existent regions R1 facing each other. The region inside the first joint 80 in the first direction D1 and outside the vertex 53 in the first direction D1 is a region where opposing surfaces face each other but are not joined and do not affect the joining. Therefore, the configuration of this region is not particularly limited.

[0044] As shown in Figure 4, the second joint 90 may have a second inner joint 91 and a second outer joint 92 located further outward in the first direction D1 than the second inner joint 91. The joint strength of the second outer joint 92 may be lower than that of the second inner joint 91. External forces acting on the housing are more likely to act on the second outer joint 92, which is located further outward in the first direction D1 than the second inner joint 91. With this configuration, because the joint strength of the second outer joint 92 is lower than that of the second inner joint 91, when an external force is applied to the housing, the joint of the second outer joint 92 is released, absorbing the deformation of the housing and suppressing the deformation of the absorbent article inside.

[0045] In the first embodiment, the second internal joint 91 joins the ink-containing region R2 and the ink-free region R1, while the second external joint 92 may join the ink-containing regions R2 together. The second internal joint 91 joins the ink-free region R1 and the ink-containing region R2, resulting in less ink dissolution and easier securing of joint strength compared to the second external joint 92. On the other hand, the second external joint 92 results in more ink dissolution than the second internal joint 91, allowing for lower joint strength. Furthermore, the second external joint 92 is located further out in the first direction D1 than the second internal joint 91, making it more visible to the user. Since at least a portion of the second external joint 92 joins the ink-containing region R2, the aesthetic appearance of the user-visible area can be enhanced by printing.

[0046] The bending rigidity of the region where the second joint 90 is provided may be lower than that of the region where the first joint 80 is provided. If the bending rigidity of the region where the second joint 90 is provided is high, when a force is applied from the outside in the first direction D1 of the housing, the region where the second joint 90 is provided will not absorb the force by deforming, and the force will be transmitted to the inside of the housing, potentially causing deformation of the absorbent article. However, because the bending rigidity of the region where the second joint 90 is provided is low, the deformation of the region where the second joint 90 is provided absorbs the external force, suppressing deformation of the internal absorbent article. Furthermore, the bending rigidity of the region where the second outer joint 92 is provided may be lower than that of the region where the second inner joint 91 is provided. With this configuration, the deformation of the region where the second outer joint 92 is provided absorbs the external force, further suppressing deformation of the internal absorbent article. Preferably, the bending rigidity of the region where the second outer joint 92 is provided < the bending rigidity of the region where the second inner joint 91 is provided < the bending rigidity of the region where the first joint 80 is provided. Since the bending rigidity of the joint located on the outer end side of the first direction D1 of the containment is relatively low and increases gradually toward the inside in the first direction, the sealed state of the containment can be maintained while absorbing external forces by releasing the joint located on the outer end side, and the absorbent article can be protected hygienically while suppressing deformation of the absorbent article.

[0047] The bending stiffness can be measured using the Gurley rigidity test method. The rigidity is measured as follows. For matters not specified, the method follows JIS L1913:2010 "General Nonwoven Fabric Test Methods" "6.7.4 Gurley Method". (1) Prepare a No. 311 Gurley flexibility tester manufactured by Yasuda Seiki Seisakusho Co., Ltd. in a constant temperature and humidity chamber at 20°C and 65% RH. (2) Cut the sample to a size of 38 mm × 12.5 mm (length direction × width direction) and prepare the sample for measurement. (3) Place the sample in a Gurley flexibility tester and measure its stiffness (1st time). Then, reverse the front and back of the sample and place it in the Gurley flexibility tester to measure its stiffness (2nd time). Calculate the average value of the stiffness measurements from the two measurements mentioned above. (4) Repeat the above measurement a total of five times with different samples, and adopt the average of the above average values ​​as the stiffness / softness. Furthermore, the bending rigidity is compared under the same conditions for the configuration (number of sheets, materials) of the storage sheets 10 joined by the first joint 80 and the configuration of the storage sheets 10 joined by the second joint 90.

[0048] The storage sheet 10 may have a vertex 53 located inside the first direction D1 of the valley fold portion, and a pair of opposing surfaces 50 extending outward from the vertex 53 in the first direction D1. The vertex 53 and the pair of opposing surfaces 50 are provided on the folding surface 11. The pair of opposing surfaces 50 have a first opposing surface 51 and a second opposing surface 52 facing each other. The first opposing surface 51 and the second opposing surface 52 sandwich the vertex 53. The vertex 53 becomes the fold of the valley fold portion. The first joint portion 80 and the second joint portion 90 join the opposing surfaces 50 together. The second joint portion 90 may be provided spaced apart from the outer end of the opposing surface 50 in the first direction D1. That is, a non-jointed region NR may be provided between the second joint portion 90 and the outer end of the opposing surface 50 in the first direction D1, where the opposing surfaces 50 are not joined together. With this configuration, when an external force is applied to the outer end of the opposing surface 50 in the first direction D1, the non-jointed region between the second joint 90 and the outer end of the opposing surface in the first direction D1 becomes a buffer region, thereby reducing the force applied to the second joint 90.

[0049] The inner edge of the first joint 80 in the first direction D1 may reach the vertex 53, or it may be spaced apart from the vertex 53. For example, if the inner edge of the first joint 80 and the vertex 53 are spaced apart in the first direction D1, a non-jointed region is provided in a certain range extending outward from the vertex 53 in the first direction D1, where opposing surfaces are not joined. This non-jointed region acts as a buffer region, suppressing the propagation of external force to the absorbent article when an external force is applied to the housing.

[0050] The storage sheet 10 may have perforations 18 extending from the outer end of the opposing surface 50 in the first direction D1 toward the inside of the first direction D1. The perforations 18 and the second joint 90 may be spaced apart in the second direction D2 which is perpendicular to the first direction D1. When a user carries the storage body 1, they may place their fingers or other body parts near the second joint 90. At this time, since the perforations 18 and the second joint 90 are spaced apart in the second direction D2, the force applied to the perforations 18 can be reduced, and the problem of the perforations 18 unintentionally opening can be suppressed. The perforations 18 only need to extend from the outer end of the opposing surface 50 in the first direction D1 toward the first direction D1, and as in this embodiment, they may be formed across both ends of the fifth surface in the first direction D1, or they may be formed on a part of the fifth surface 105 in the first direction D1. Furthermore, the perforations 18 may be provided on both sides of the joint (first joint 80, second joint 90) in the second direction D2, or they may be provided only on one side of the joint in the second direction.

[0051] The bending stiffness of the outer end of the first opposing surface 51 in the first direction D1 and the bending stiffness of the outer end of the second opposing surface 52 in the first direction D1 may be different. It is sufficient that, in at least one of the pair of opposing surfaces (the opposing surface on the third side and the opposing surface on the fourth side), the bending stiffness of the outer end of the first opposing surface 51 in the first direction D1 and the bending stiffness of the outer end of the second opposing surface in the second direction are different. In this embodiment, a welded portion 55 is formed at the edge of the first opposing surface 51 in the first direction D1, where the containment sheets 10 are welded together, while no welded portion 55 is formed at the edge of the second opposing surface 52 in the first direction D1. If the bending rigidity of the outer end of the first opposing surface 51 in the first direction D1 is the same as the bending rigidity of the outer end of the second opposing surface 52 in the first direction D1, the angle of the joint between the first opposing surface 51 and the second opposing surface 52 is unlikely to tilt to one side. When a force is applied to the outer ends of the first opposing surface 51 and the second opposing surface 52 in the first direction D1, the force is applied equally to both the first opposing surface 51 and the second opposing surface 52, which may cause the first opposing surface 51 and the second opposing surface 52 to deform and separate from each other. However, because the bending rigidity of the outer end of the first opposing surface 51 in the first direction D1 is relatively high, the joint between the first opposing surface 51 and the second opposing surface 52 tilts towards the second opposing surface 52. Therefore, it becomes less likely that the force is applied equally to both the first opposing surface 51 and the second opposing surface 52, and the force can be distributed. Thus, deformation that causes the first opposing surface 51 and the second opposing surface 52 to separate from each other can be suppressed. Furthermore, the welded portion 55 extends continuously along the boundary between the folded surface 11 and the non-folded surface 12. Therefore, the welded portion 55 may be formed continuously on the first surface 101, the third surface 103, the fifth surface 105, and the sixth surface 106.

[0052] As shown in Figures 2 to 4, an ink-free region R1 may be provided at the outer end of the first opposing surface 51 in the first direction D1. An ink-present region R2 may be provided at the outer end of the second opposing surface 52 in the first direction D1. With this configuration, the boundary between the first opposing surface 51 and the second opposing surface 52, and the position of the joint, can be easily determined by distinguishing between the ink-present region R2 and the ink-free region R1. Therefore, it is possible to suppress the release of the joint state due to unintentional contact of fingers or other objects with the joint. The ink-free region R1 is provided along the boundary between the folding surface 11 and the non-folding surface, and spans the folding surface 11 and the non-folding surface 12. On the folding surface 11 and the non-folding surface 12, an ink-free region R1 is provided with a certain width (10 mm or less, preferably 5 mm or less) from the boundary, and an ink-present region R2 is provided adjacent to the ink-free region R1. Furthermore, the first opposing surface 51 on which the ink-free region R1 is provided may be the same as the first opposing surface 51 on which the welded portion 55 (the portion with high bending rigidity) is provided. With this configuration, the outer edge of the first opposing surface 51 becomes more conspicuous and easier to distinguish from the second opposing surface 52.

[0053] As shown in Figure 4(a), in the first direction D1, the outer edge of the first opposing surface 51 may be located further out than the outer edge of the second opposing surface 52. Therefore, the first opposing surface 51 extends further out than the second opposing surface 52. Thus, when an external force is applied to the outer end of the container in the first direction D1, the portion of the first opposing surface 51 that protrudes beyond the second opposing surface 52 becomes a buffer area, reducing the force applied to the second joint 90. Thus, unintended separation of the second joint 90 is suppressed, the absorbent article is protected, and the aesthetic appearance of the container is maintained.

[0054] As shown in Figure 4, the joint may have an upper joint 95 provided on the upper surface (fifth surface 105) and a lower joint 96 provided on the lower surface (sixth surface 106). The first joint 80 of the upper joint 95 and the first joint 80 of the lower joint 96 are provided spaced apart in the first direction D1. The distance (G95) between the first joint 80s in the upper joint 95 in the first direction D1 may be different from the distance (G96) between the first joint 80s in the lower joint 96 in the first direction D1. The region between the first joint 80s is a region where no first joint 80s are provided, has low rigidity, and is likely to become a buffer region. Because the length of the first direction D1 of this buffer region differs between the upper and lower surfaces, when a force is applied from outside the first direction D1 of the housing 1, both the upper and lower surfaces do not deform in the same way, and the deformation of one side can suppress the deformation of the other side. Furthermore, in the valley-fold portion (side region 1S shown in Figure 4), four storage sheets 10 are stacked, while in the region inside the first direction D1 from the valley-fold portion (central region 1C shown in Figure 4), two storage sheets 10 are stacked. The first joint 80 is provided in the portion where four storage sheets 10 are stacked, and is located near the vertex 53 (for example, adjacent to the vertex 53). Therefore, the region between the first joint 80 in the first direction D1 has fewer storage sheets 10, resulting in lower rigidity and making it prone to becoming a buffer region. Because the length of the buffer region in the first direction D1 differs between the top and bottom surfaces, when a force is applied from the outside of the storage body in the first direction D1, both the top and bottom surfaces do not deform in the same way, and the deformation of one side can suppress the deformation of the other side.

[0055] The area of ​​the first joint 80 at the upper joint 95 may be larger than the area of ​​the first joint 80 at the lower joint 96. For example, the length of the first joint 80 at the upper joint 95 in the first direction D1 (lateral direction) may be longer than the length of the first joint 80 at the lower joint 96 in the first direction D1, or the length of the first joint 80 at the upper joint 95 in the third direction (third direction shown in Figure 3) may be longer than the length of the first joint 80 at the lower joint 96 in the third direction. When a user grasps the container, it is easier to hold the upper side than the lower side. Because the area of ​​the first joint 80 on the upper surface is relatively large, it is easy to maintain the joined state of the first joint 80 even when an external force is applied to the upper surface. On the other hand, the lower surface is the bottom surface on which the container is placed, and if the area of ​​the first joint 80 is too large, the rigidity will be locally high only at the location of the first joint 80, which may prevent the container from being placed stably. However, because the area of ​​the first joint 80 on the lower surface is relatively small, the container can be placed stably. Also, the area of ​​the second joint of the upper joint and the area of ​​the lower joint 96 may be different. In a configuration where the area of ​​the joint of the upper joint 95 and the area of ​​the joint of the lower joint 96 are different, the area of ​​the ink-free region R1 corresponding to the upper joint and the area of ​​the ink-free region R1 corresponding to the lower joint 96 may be different.

[0056] The storage sheet 10 may have a base layer made of thermoplastic resin and an ink layer on the outer side of the base layer where ink is applied. The melting point of the ink may be higher than the melting point of the base layer. With this configuration, when the sheets are welded at a temperature at which the base layer melts, the ink is less likely to melt, discoloration of the ink can be suppressed, and the aesthetic appearance can be maintained. The ink layer, which has an ink with a melting point higher than the melting point of the base layer, may constitute the outer surface of the storage sheet 10, and a second ink layer, which has an ink with a melting point lower than the melting point of the base layer, may be provided between the ink layer and the base layer. With this configuration as well, when the sheets are welded at a temperature at which the base layer melts, the ink constituting the outer surface of the storage sheet 10 is less likely to melt, discoloration of the ink can be suppressed, and the aesthetic appearance can be maintained.
