Problems to be solved by the invention
When the absorbent article is inserted into the hem pocket, the absorbent article (individual package) is pressed and inserted in the thickness direction in a state where a plurality of the absorbent articles are stacked. In this case, if the absorbent article is excessively pressed, the absorbent core may become locally stiff, and the absorbent performance may be impaired or the wearing sensation may be deteriorated. Therefore, in order not to excessively press the absorbent article, the laminate of the absorbent article is inserted with a margin with respect to the inner dimension of the package. If the internal dimensions of the package bag and the external dimensions of the laminate are made different in this way, the positions of the receiving pieces at the piece joint portions are easily shifted from each other. Therefore, it is sometimes difficult to form the sheet joint portion aesthetically.
In addition, when producing the storage body of the absorbent article, a plurality of storage bodies are continuously produced, the sheet joint is formed, and the storage sheet is cut in the vicinity of the sheet joint, thereby obtaining each storage body. In this case, a sheet edge portion in which the receiving sheets are stacked without being bonded to each other may be formed on the outer side of the sheet bonding portion. If the storage pieces are offset from each other in the storage body in which the piece edge portions are formed, the offset of the storage pieces from each other is easily noticeable in the piece edge portions, and the appearance may be impaired. Further, if the storage sheets are shifted from each other in position, the shifted portions may be caught, and the sheet joint may be unintentionally opened by the catching. Therefore, there is a possibility that the absorbent article cannot be stored in a sanitary manner.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a storage body for an absorbent article and a package group for an absorbent article, which can prevent the aesthetic deterioration of the storage body due to a sheet edge portion extending from a sheet joint portion and can sanitarily store the absorbent article.
Solution for solving the problem
In the absorbent article storage according to one aspect, a plurality of absorbent articles having absorbent cores are stored in a storage sheet made of thermoplastic resin. A sheet joint part formed by mutually jointing the storage sheets and a sheet edge part formed by extending the storage sheets to a position which is positioned outside the storage body than the sheet joint part are arranged on the 1 st surface of the storage body. The sheet engaging portion and the sheet edge portion are contiguous in the extending direction and have a predetermined length in the extending direction. The length of the sheet edge portion in the extending direction is shorter than the length of the sheet engaging portion in the extending direction.
The package group of absorbent articles according to one aspect includes a plurality of storage bodies for absorbent articles. The storage body includes a 1 st storage body and a 2 nd storage body having a longer length in the extending direction than the 1 st storage body. The 1 st length in the extending direction of the portion of the 1 st housing body obtained by adding the sheet joining portion and the sheet edge portion is the same as the 2 nd length in the extending direction of the portion of the 2 nd housing body obtained by adding the sheet joining portion and the sheet edge portion.

Detailed Description
(1) Summary of the embodiments
At least the following matters will be apparent from the description of the present specification and drawings.
In the absorbent article storage according to one aspect, a plurality of absorbent articles having absorbent cores are stored in a storage sheet made of thermoplastic resin. A sheet joint part formed by mutually jointing the storage sheets and a sheet edge part formed by extending the storage sheets to a position which is positioned outside the storage body than the sheet joint part are arranged on the 1 st surface of the storage body. The sheet engaging portion (11) and the sheet edge portion (12) are contiguous in an extending direction (Z) and have a predetermined length in the extending direction. The length (Z12) of the sheet edge portion in the extending direction is shorter than the length (Z11) of the sheet joint portion in the extending direction. According to the present invention, since the length of the sheet edge portion in the extending direction is relatively short, even when the sheet edge portion is disposed along the outer surface of the 1 st surface without standing up, it is difficult for the sheet edge portion to obstruct display of the design of the 1 st surface of the storage body or the like. Further, since the length in the extending direction of the sheet edge portion is relatively short, even when the sheet edge portion stands up, deterioration in the appearance due to unstable arrangement of the sheet edge portion having relatively low rigidity can be suppressed. On the other hand, since the length of the sheet joint portion in the extending direction is long, the joint strength of the sheet joint portion can be ensured. Therefore, even if the user erroneously wants to unseal the sheet joined portion, the user cannot unseal the sheet joined portion, and can continuously and hygienically store the absorbent article.
According to a preferred embodiment, the receiving sheet has a 1 st region and a 2 nd region which are joined at the sheet joining portion and are overlapped in a separable manner at the sheet edge portion. The sheet edge portion has a root end on the sheet joint portion side and a tip end on a side of the sheet edge portion opposite to the root end. In a natural state of the storage body, a 1 st virtual line (FL 1) connecting the root end and the tip end of the sheet edge portion at the 1 st region forms an angle of 25 degrees or less with respect to the extending direction. In a natural state of the storage body, an angle of a 2 nd virtual line (FL 2) connecting the root end and the tip end of the sheet edge portion at the 2 nd region with respect to the extending direction is 25 degrees or less. According to this aspect, since the two sheet edge portions stand up and are not arranged along the outer surface of the 1 st surface, the sheet edge portions are less likely to obstruct the display of the design of the 1 st surface of the storage body, and the like, and the aesthetic deterioration of the storage body can be suppressed.
According to a preferred embodiment, the sheet engaging portion and the sheet edge portion extend along a 1 st direction orthogonal to the extending direction. The receiving sheet has a 1 st region and a 2 nd region joined at the sheet joining portion and overlapped in a separable manner at the sheet edge portion. The sheet joint portion has a plurality of pressing portions in which the 1 st region and the 2 nd region are pressed together. The pressing portion has a 1 st pressing portion (41) recessed from the 1 st region side toward the 2 nd region side and a 2 nd pressing portion (42) recessed from the 2 nd region side toward the 1 st region side. The 1 st pressing portion and the 2 nd pressing portion are arranged so as to be offset in either one of the 1 st direction and the extending direction. According to the present embodiment, by providing the 1 st pressing portion and the 2 nd pressing portion, the sheet joint portion is easily restored even if deformed against an external force, and therefore the sheet edge portion and the sheet joint portion are easily maintained in the raised state. Further, since the sheet joined portion is easily restored even if deformed, local application of force to the absorbent core is suppressed, and the absorbent performance can be maintained.
According to a preferred embodiment, the 1 st pressing portions and the 2 nd pressing portions are alternately arranged in the 1 st direction. According to the present invention, a plurality of deformation starting points are formed in the sheet joint portion along the 1 st direction. Therefore, the sheet joint portion is easily restored upon deformation, and the sheet joint portion and the sheet edge portion are easily maintained in the standing state. Further, since the sheet joined portion is easily restored even if deformed, local application of force to the absorbent core is suppressed, and the absorption performance can be further maintained.
According to a preferred embodiment, the sheet joint portion has: the high compression part of the pressing part and the low compression part with relatively lower compression degree than the high compression part are provided. According to the present invention, since the high compression portion and the low compression portion having different rigidities are formed in the sheet joint portion, the deformation starting point is formed in the sheet joint portion due to the difference in rigidity. Therefore, the sheet joint portion is easily restored upon deformation, and the sheet joint portion and the sheet edge portion are easily maintained in the standing state. Further, since the sheet joined portion is easily restored even if deformed, local application of force to the absorbent core is suppressed, and the absorbent performance can be maintained.
According to a preferred embodiment, the sheet joint portion is provided with a coloring region for coloring the receiving sheet. At least a part of the pressing portion is provided in the colored region. The colored areas carry pigment or ink and tend to increase in stiffness as compared to the non-colored areas. By providing the pressing portion in the colored region, the colored region can be easily raised, and the sheet joint portion can be more easily maintained in the raised state.
According to a preferred embodiment, the tip of the edge portion of the sheet is formed in a zigzag or wavy shape. According to the present invention, a plurality of deformation starting points separated in the 1 st direction are formed at the tip end of the sheet edge portion. Therefore, the sheet edge portion is easily restored when deformed, and the sheet edge portion is easily maintained in the raised state.
According to a preferred embodiment, the sheet engaging portion and the sheet edge portion extend along a 1 st direction orthogonal to the extending direction. The storage body has a 2 nd surface (102) disposed opposite to the 1 st surface (101). The sheet joint portion and the sheet edge portion are provided on the 2 nd surface. The sheet engaging portion of the 1 st surface and the sheet engaging portion of the 2 nd surface are inclined in the same direction with respect to a virtual line along the 1 st direction. According to the present aspect, the sheet joint portion of the 1 st surface and the sheet joint portion of the 2 nd surface are inclined in the same direction, so that the torsional force is not applied to the absorbent core of the absorbent article, and the absorption performance can be ensured.
According to a preferred embodiment, the sheet engaging portion and the sheet edge portion extend along a 1 st direction orthogonal to the extending direction. The storage body has a 2 nd surface (102) disposed opposite to the 1 st surface (101). The sheet joint portion and the sheet edge portion are provided on the 2 nd surface. The sheet engaging portion of the 2 nd face and the sheet engaging portion of the 1 st face are inclined in opposite directions with respect to a virtual line along the 1 st direction. According to the present invention, the sheet joint portion of the 1 st surface and the sheet joint portion of the 2 nd surface are inclined in opposite directions, so that the storage body can be stably arranged by the forces acting and supported by the respective sheet joint portions in different directions.
According to a preferred embodiment, the housing has a 2 nd surface disposed opposite to the 1 st surface. The sheet joint portion and the sheet edge portion are provided on the 2 nd surface. When the interval in the extending direction between the 1 st-surface sheet joined portion and the 2 nd-surface sheet joined portion is G11, the length in the extending direction of the absorbent article is Z20, the length in the extending direction of the 1 st-surface sheet joined portion is Z111, and the length in the extending direction of the 2 nd-surface sheet joined portion is Z112, (z111+z112) > (G11-Z20) is satisfied. According to the present embodiment, (z111+z112) is a region which is relatively rigid and difficult to deform. On the other hand, (G11-Z20) is a length in which the absorbent article can move in the storage body, and is an area that is easily deformed. Since the length of the region that is liable to be deformed is short, (z111+z112) can suppress misalignment of the storage bodies with each other and suppress displacement of the absorbent article in the storage bodies.
According to a preferred embodiment, Z111 < (G11-Z20) and Z112 < (G11-Z20) are satisfied. According to this aspect, (G11-Z20) is a length of a space in the storage body that can absorb the displacement of the absorbent article, and is a relatively easy-to-deform region. Since Z111 (Z112) is shorter than (G11-Z20), deformation of the absorbent article can be suppressed even if the 1 st-surface sheet joint portion (or the 2 nd-surface sheet joint portion) is pressed toward the inside of the storage body.
According to a preferred embodiment, the sheet engaging portion and the sheet edge portion extend along a 1 st direction orthogonal to the extending direction. The storage sheet has a 1 st region and a 2 nd region which are joined at the sheet joining portion and are overlapped in a separable manner at the sheet edge portion. When the length of the shift in the 1 st direction between the 1 st region and the 2 nd region is X13, Z111 > X13 is satisfied and Z112 > X13 is satisfied. According to the present embodiment, if the length X13 in the 1 st direction of the misalignment (extending portion) is longer than the length in the extending direction of the sheet joint portion 11, the extending portion becomes conspicuous to cause deterioration in appearance, and the extending portion may be caught to cause the sheet joint portion to be unintentionally unsealed. However, since Z111 > X13 and Z112 > X13 are satisfied, the width of the sheet joint portion is ensured to be equal to or longer than the length of the extension portion, and thus deterioration in appearance can be suppressed, and unintentional opening of the sheet joint portion can be suppressed.
According to a preferred embodiment, the sheet joint portion may be provided with a display portion for displaying information of the absorbent article. According to the present invention, the display portion of the sheet joint portion is used to draw attention of the user, so that the sheet edge portion is made less noticeable, and the deterioration of the appearance due to the sheet edge portion can be suppressed.
The package group of absorbent articles according to one aspect includes a plurality of storage bodies for absorbent articles. The storage body includes a 1 st storage body and a 2 nd storage body having a longer length in the extending direction than the 1 st storage body. The 1 st length in the extending direction of the portion of the 1 st housing body obtained by adding the sheet joining portion and the sheet edge portion is the same as the 2 nd length in the extending direction of the portion of the 2 nd housing body obtained by adding the sheet joining portion and the sheet edge portion. The lengths in the extending direction of the entire storage bodies of the 1 st storage body and the 2 nd storage body are different, but the lengths (1 st length and 2 nd length) of the portions obtained by adding the sheet joining portion and the sheet edge portion together are the same. The 2 nd container is larger than the 1 st container, and the proportion of the sheet joint portion and the sheet edge portion is lower, thereby improving the beauty. Further, the ratio of the sheet joined portion and the sheet edge portion is different, but since the 1 st length and the 2 nd length are the same, the consumer easily recognizes that the package group is the 1 st container and the 2 nd container.
(2) Structure of storage body for absorbent article
Hereinafter, a case 1 (hereinafter, case 1) for an absorbent article according to an embodiment will be described with reference to the drawings. In the description of the drawings below, the same or similar parts are denoted by the same or similar reference numerals. However, the drawings are schematic, and it should be noted that the ratio of the dimensions and the like are different from the actual ratio and the like. Thus, specific dimensions and the like should be determined with reference to the following description. Further, the drawings may include portions having different dimensional relationships and proportions.
Fig. 1 is a perspective view of a housing 1 according to an embodiment. Fig. 2 is a plan view of the storage body 1. Fig. 3 (a) and 3 (B) are enlarged views of a portion a of fig. 2. Fig. 3 (a) shows a natural state, and fig. 3 (B) shows an extended state. Here, the natural state means that the storage body 1 is placed on a flat plate, the sheet joint portions on both sides are held horizontally with the hand and the extending direction, and the sheet joint portion 11 is pulled to the outside in the extending direction Z to such an extent that wrinkles on the front and rear surfaces of the storage body are not visible. Then, the stretched hand was released and left to stand at 20.+ -. 2 ℃ and 50% humidity for 30 minutes. The extended state is a state in which the sheet joining portions on both sides are gripped by hands, and the sheet joining portion 11 is pulled outward in the extending direction Z to such an extent that wrinkles on the front and rear surfaces of the housing are not visible. In the structure in which the sheet joining portion is formed in the region overlapping the fold formed in the storage sheet when joining the storage sheet, the sheet joining portions on both sides may be stretched until the fold other than the fold overlapping the sheet joining portion is not visible.
The storage body 1 packages a plurality of absorbent articles 20 with the storage sheet 10. The storage body 1 has a storage space 5, and the absorbent article 20 is stored in the storage space 5 by folding and joining the storage sheet 10 to the storage sheet 10. A plurality of absorbent articles 20 are accommodated in the accommodation space 5. Examples of the absorbent article 20 include disposable diapers, sanitary napkins, incontinence pads, and panty liners. The absorbent article 20 may be stacked in the thickness direction of the absorbent article 20 in the storage body 1. The absorbent article 20 may be housed in the housing 1 in a state of being only the main body 21 (sanitary napkin, disposable diaper, etc.) used at the time of use, or may be housed in the housing 1 in a state of being individually packaged by the packaging sheet 22 (see fig. 2).
The absorbent article 20 can be used as is well known as the absorbent article 20. However, it is preferable that the absorbent article 20 having a relatively soft absorbent core can be suitably used. As will be described later, the storage body 1 according to the present embodiment is configured to suppress local stiffening of the absorbent core. Specifically, the region of the absorbent article 20 including the absorbent core may have a bending stiffness value of 5.0mN·m to 35.0mN·m in the longitudinal direction and the width direction. The bending stiffness is measured, for example, according to the following procedure. (1) A torque tester made of IMADA and EX-0762 were prepared in a constant temperature and humidity chamber (20.+ -. 2 ℃ C., 60.+ -. 5% RH). The load sensor was set to 50N for stretching and compression, and the torque was set to 1N. (2) the samples were cut as shown in Table 1. (3) The jig was adhered to both ends of the sample in the measurement direction so that the longitudinal direction thereof was perpendicular to the measurement direction, and grip portions were formed at both ends of the sample in the measurement direction, as shown in table 1. (4) The samples were mounted on a jig, and the maximum torque values (mn·m) thereof were measured under the conditions shown in table 1. (5) The measurements were performed 5 times with different samples, their average value being taken as bending stiffness value.
[ Table 1 ]
The storage sheet 10 may be formed of a resin film and formed into a substantially rectangular shape. The housing 1 may be a hexahedron having 1 st to 6 th surfaces 101 to 106 in a substantially rectangular shape. The 1 st to 6 th surfaces 101 to 106 may be rectangular surfaces. The 1 st to 6 th surfaces 101 to 106 may intersect each other in a curved line, instead of perpendicularly intersecting each other. The 1 st surface 101 and the 2 nd surface 102 are arranged to face each other, the 3 rd surface 103 and the 4 th surface 104 are arranged to face each other, and the 5 th surface 105 and the 6 th surface 106 are arranged to face each other. The 1 st surface 101 is a surface provided with a sheet joint portion 11 described later. In a case where the sheet joining portion 11 is provided on a plurality of surfaces (the sheet joining portion 11 of the present embodiment is provided on the 1 st surface 101 and the 2 nd surface 102), any one of the surfaces on which the sheet joining portion 11 is formed may be the 1 st surface 101. A cut line 3 may be formed in the storage body 1, and the cut line 3 is used to form an opening for taking out the absorbent article 20. The shear line 3 of the present embodiment is provided on the 1 st surface, and extends along the 1 st direction X with a gap in the 2 nd direction Y from the sheet joint portion 11.
The housing 1 has a 1 st direction X, a 2 nd direction Y, and an extending direction Z, which are orthogonal to each other. The 1 st surface 101 and the 2 nd surface 102 are surfaces surrounded by a side extending in the 1 st direction X and a side extending in the 2 nd direction Y. The 1 st face 101 and the 2 nd face 102 are separated in the extending direction Z and are opposed to each other. The 3 rd surface 103 and the 4 th surface 104 are surfaces surrounded by a side extending in the 1 st direction X and a side extending in the extending direction Z. The 3 rd surface 103 and the 4 th surface 104 are separated in the 2 nd direction Y and are opposed to each other. The 5 th surface 105 and the 6 th surface 106 are surfaces surrounded by a side extending in the 2 nd direction Y and a side extending in the extending direction Z. The 5 th face 105 and the 6 th face 106 are separated in the 1 st direction X and are opposed to each other. In the storage body 1 of the present embodiment, the 3 rd surface 103 and the 4 th surface 104 have a large area, and the 3 rd surface 103 forms the front surface and the 4 th surface 104 forms the back surface, respectively, out of the 1 st surface 101 to the 6 th surface 106. The 5 th surface 105 constitutes an upper surface, and the 6 th surface 106 constitutes a lower surface. The 1 st face 101 and the 2 nd face 102 constitute side faces. In the state shown in fig. 1, the 1 st direction X extends in the longitudinal direction, the 2 nd direction Y extends in the depth direction, and the extending direction Z extends in the lateral direction. The extending direction Z is a direction in which a sheet joining portion 11 and a sheet edge portion 12 described later abut.
The storage sheet 10 may be made of a sheet made of thermoplastic resin. The storage sheet 10 may be a laminate sheet formed by stacking at least a sheet made of a thermoplastic resin and other sheets. The sheet joining portion 11 is a portion where the receiving sheets 10 are joined to each other. The portions may be joined by welding such as thermal welding or ultrasonic welding, or may be bonded by an adhesive. The sheet edge portion 12 is located outside the sheet joint portion 11 in the extending direction Z. The sheet edge portion 12 is a portion where the receiving sheets 10 are not joined to each other or a portion where the receiving sheets 10 are joined to each other with a weaker joining force than the sheet joining portion 11. The sheet engaging portion 11 and the sheet edge portion 12 extend along the 1 st direction X. The sheet engaging portion 11 and the sheet edge portion 12 are contiguous in the extending direction Z, and have a predetermined length in the extending direction Z. The sheet joint portion 11 and the sheet edge portion 12 are provided on the 1 st surface 101. The sheet joining portion 11 and the sheet edge portion 12 may be provided on a surface other than the 1 st surface 101, and in the present embodiment, may be provided on the 2 nd surface 102. In this embodiment, the structure extending in a certain direction is a concept as follows: not only the structure parallel to the direction but also the structure extending at less than 45 degrees with respect to the direction. Preferably, the sheet engaging portion 11 and the sheet edge portion 12 may be inclined by less than 10 degrees with respect to the 1 st direction X, and more preferably, the sheet engaging portion 11 and the sheet edge portion 12 may be inclined by less than 5 degrees with respect to the 1 st direction X.
Next, the structure of the storage body 1 configured as described above for storing the absorbent article 20 in a sanitary manner while suppressing the deterioration of the aesthetic appearance of the storage body 1 will be described in detail. As shown in fig. 3 (a) and 3 (B), the length Z12 of the sheet edge portion 12 of the housing body 1 in the extending direction Z is shorter than the length Z11 of the sheet joint portion 11 in the extending direction Z. In general, a flexible material is often used for the storage sheet 10. Therefore, unless otherwise mentioned, the positional relationship and the length of the present embodiment are measured in the extended state of the storage body 1. Therefore, Z12 < Z11 can be satisfied in a state where the sheet joining portion 11 and the sheet edge portion 12 are elongated in the extending direction Z. In a configuration in which the length Z11 in the extending direction Z of the sheet joining portion 11 and the length Z12 in the extending direction Z of the sheet edge portion 12 are changed in position in the 1 st direction X, the positions of the sheet joining portion 11 and the sheet edge portion 12 adjacent to each other are compared. Specifically, a virtual line parallel to the extending direction Z may be drawn, and Z12 < Z11 may be satisfied on the virtual line. In the case of the storage body 1 of the present embodiment, the length of the sheet edge portion 12 in the extending direction Z is relatively short. Therefore, even when the sheet edge portion 12 is arranged along the outer surface of the 1 st surface 101 without standing up, the sheet edge portion 12 is difficult to prevent the display of the design or the like of the 1 st surface 101. Further, even when the sheet edge portion 12 is raised, deterioration of the appearance due to unstable arrangement of the sheet edge portion 12 having relatively low rigidity can be suppressed.
When the absorbent article 20 is inserted into the hem pocket (storage sheet 10), the plurality of absorbent articles 20 are pressed and inserted in the thickness direction in a stacked state. At this time, if the absorbent core is excessively pressed, the absorbent core may become locally hard, and the absorption performance may be impaired or the wearing feel may be deteriorated. Therefore, in order not to excessively press the absorbent article 20, the laminate of the absorbent article 20 is inserted with a margin with respect to the inner dimension of the bag. When the internal dimensions of the bag and the external dimensions of the laminate are made different in this way, the positions of the receiving sheet 10 at the sheet joining portion 11 and the sheet edge portion 12 are easily shifted from each other. Fig. 4 is an enlarged view of the portion B shown in fig. 1, showing the misalignment of the storage pieces 10. As shown in fig. 4, when the sheet joint 11 is formed in a state in which the storage sheet 10 on the 3 rd surface 103 side and the storage sheet 10 on the 4 th surface 104 side are shifted in the 1 st direction X, a portion (corresponding to the sheet joint 11) obtained by joining the two storage sheets and a portion (a portion indicated by a diagonal line in fig. 4 and a reference numeral 13) obtained by joining only one storage sheet (the storage sheet 10 on the 4 th surface 104 side in fig. 4) are formed. Therefore, an extension portion 13 in which one storage sheet extends is formed at a position outside the 1 st direction X of the sheet joining portion 11 formed by joining the two storage sheets 10, and a portion (corresponding to the sheet edge portion 12) at which the two storage sheets overlap without joining is formed at a position outside the extension direction Z of the sheet joining portion 11. If the length of the sheet edge portion 12 in the extending direction Z is relatively long, the extending portion 13 formed by the misalignment of the storage sheets 10 is also easily noticeable, and the appearance may be impaired. However, since the length Z12 in the extending direction Z of the sheet edge portion 12 is short, the misalignment of the storage sheets 10 can be made less noticeable. On the other hand, since the length Z11 in the extending direction Z of the sheet joint portion 11 is long, the sheet joint portion 11 having relatively high rigidity stands up, and the sheet edge portion 12 is also easily lifted up following the sheet joint portion 11. By raising the sheet edge 12 as well, the deterioration of the appearance of the storage body 1 due to the sheet edge 12 along the 1 st surface 101 (lodging) can be suppressed. Further, since the length Z11 in the extending direction Z of the sheet bonding portion 11 is long, the bonding strength of the sheet bonding portion 11 can be ensured. Therefore, even if the user erroneously wants to unseal the sheet joined portion 11, the user cannot unseal the sheet joined portion, and can continuously and hygienically store the absorbent article 20.
The length Z11 of the sheet joint 11 in the extending direction may be 1mm or more, and preferably 1.5mm or more. Further, the length Z12 in the extending direction of the sheet edge portion 12 may be less than 1.5mm, and preferably may be less than 1.0mm. The ratio of the length Z12 in the extending direction of the sheet edge portion 12 to the length Z11 in the extending direction of the sheet joint portion 11 may be less than 1.0, but may be preferably 0.7 or less.
As shown in fig. 3 (a), the storage sheet 10 may have a 1 st region R1 and a 2 nd region R2 joined at the sheet joining portion 11 and overlapped in a separable manner at the sheet edge portion 12. The 1 st region R1 is located on the 3 rd surface 103 side and is located in a region extending from the 3 rd surface 103. The 2 nd region R2 is located on the 4 th surface 104 side and is located in a region extending from the 4 th surface 104. The sheet edge portion 12 has a root end 121 on the sheet joint portion 11 side and a tip end 122 on the opposite side of the sheet edge portion 12 from the root end 121. In the natural state of the storage body 1, an angle α formed by the 1 st virtual line FL1 of the root end 121 and the tip end 122 of the connecting piece edge portion 12 in the 1 st region R1 with respect to the extending direction Z may be 25 degrees or less. In the natural state of the storage body 1, the angle β formed by the 2 nd virtual line FL2 of the root end 121 and the tip end 122 of the connecting piece edge portion 12 in the 2 nd region R2 with respect to the extending direction Z may be 25 degrees or less. According to this structure, since the two sheet edge portions 12 stand up and are not arranged along the outer surface of the 1 st surface 101, the sheet edge portions 12 hardly prevent display of the design of the 1 st surface 101 or the like.
The angle between the 1 st virtual line FL1 and the 2 nd virtual line FL2 is 50 degrees or less. If only one of the regions stands up and the other is disposed along the outer surface of the 1 st surface 101, the 1 st region R1 and the 2 nd region R2 are disposed apart, and if one of the regions is caught or the like, the 1 st region R1 and the 2 nd region R2 are pulled in the direction of being apart, which may cause the sheet joint portion 11 to be unintentionally opened. However, since the 1 st region R1 and the 2 nd region R2 form an acute angle of 50 degrees or less and are disposed along each other, the sheet joint portion 11 can be prevented from being unintentionally unsealed. The angle between the 1 st virtual line FL1 and the 2 nd virtual line FL2 may be 50 degrees or less, but may be 25 degrees or less, and may be 10 degrees or less.
Fig. 5 (a) and 5 (B) are diagrams schematically showing a cross section of the sheet joint portion 11. Fig. 5 (a) and 5 (B) are cross sections based on the center in the extending direction of the sheet joint portion 11. Fig. 5 (a) shows the sheet joint portion 11 of the present embodiment, and fig. 5 (B) shows the sheet joint portion 11 of the comparative example. The sheet bonding portion 11 includes a plurality of pressing portions 40 in which the 1 st region R1 and the 2 nd region R2 are pressed together. The pressing portion 40 may be provided in plurality along the 1 st direction X. The pressing portion 40 may have a 1 st pressing portion 41 recessed from the 1 st region R1 side toward the 2 nd region R2 side and a 2 nd pressing portion 42 recessed from the 2 nd region R2 side toward the 1 st region R1 side. That is, the pressing portion 40 is formed by being pressed from the 1 st region R1 side and is also formed by being pressed from the 2 nd region R2 side. The 1 st pressing portion 41 and the 2 nd pressing portion 42 are arranged so as to be offset in either one of the 1 st direction X and the extending direction Z. That is, the position of the 1 st pressing portion 41 and the position of the 2 nd pressing portion 42 in the 1 st direction X may be different, or the position of the 1 st pressing portion 41 and the position of the 2 nd pressing portion 42 in the extending direction Z may be different. In the present embodiment, the position of the 1 st pressing portion 41 and the position of the 2 nd pressing portion 42 in the extending direction Z coincide, and the position of the 1 st pressing portion 41 and the position of the 2 nd pressing portion 42 in the 1 st direction X are different.
For example, in a configuration having only the pressing portion 40 pressed from one side of the 1 st region R1 and the 2 nd region R2 as in the comparative example shown in fig. 5 (B), the bending stiffness with respect to the external force from the one side and the bending stiffness with respect to the external force from the other side are different. Therefore, the sheet edge portion 12 and the sheet joint portion 11 are difficult to maintain in a standing state, and the design of covering the outer surface of the housing 1 may deteriorate the aesthetic appearance of the housing. However, by providing the 1 st pressing portion 41 and the 2 nd pressing portion 42, the sheet joining portion 11 is easily restored in deformation against any external force in any direction, and therefore the sheet edge portion 12 and the sheet joining portion 11 are easily maintained in the raised state. Further, since the sheet joint portion 11 is easily restored even if deformed, local application of force to the absorbent core is suppressed, and the absorbent performance can be maintained.
The 1 st pressing portion 41 and the 2 nd pressing portion 42 may be alternately arranged in the 1 st direction X. Since the 1 st pressing portion 41 and the 2 nd pressing portion 42 are alternately arranged in the 1 st direction X in which the sheet joining portion 11 extends, a plurality of deformation starting points are formed in the sheet joining portion 11 along the 1 st direction X. Therefore, when the sheet joining portion 11 is deformed, the original state is easily restored, and the sheet joining portion 11 and the sheet edge portion 12 are easily maintained in the raised state. Further, since the sheet joined portion 11 is easily restored even if deformed, local application of force to the absorbent core is suppressed, and the absorption performance can be further maintained.
The sheet engaging portion 11 may have: a high compression portion of the pressing portion 40 and a low compression portion having a relatively lower compression degree than the high compression portion are provided. The compression degree can be compared with the amount of press-in during compression or the depth of the compressed portion. In the present embodiment, the 1 st pressing portion 41 constitutes a high compression portion, and the 2 nd pressing portion 42 constitutes a low compression portion. Since the sheet joint portion 11 is formed with the high compression portion and the low compression portion having different rigidities, the deformation starting point is formed in the sheet joint portion 11 due to the difference in rigidity. Therefore, the sheet joint portion 11 is easily restored upon deformation, and the sheet joint portion 11 and the sheet edge portion 12 are easily maintained in the standing state. Further, since the sheet joint portion 11 is easily restored even if deformed, local application of force to the absorbent core is suppressed, and the absorbent performance can be maintained.
In fig. 1, for convenience of explanation, the shapes of the sheet joint portion 11 and the sheet edge portion 12 of the 1 st face 101 are shown differently from the shapes of the sheet joint portion 11 and the sheet edge portion 12 of the 2 nd face 102. However, the housing 1 may have the same shape as the sheet joint 11 and the sheet edge 12 of the 1 st surface 101 and the sheet joint 11 and the sheet edge 12 of the 2 nd surface 102. As shown in the sheet joint 11 of the 2 nd surface 102, a coloring region R3 for coloring the storage sheet 10 may be provided in the sheet joint 11. The colored region R3 is a region where the storage sheet is colored with pigment or ink. At least a part of the pressing portion 40 may be provided in the colored region R3. The colored region R3 tends to be increased in rigidity as compared with the non-colored region due to pigment or ink. By providing the pressing portion 40 in the colored region R3, the colored region R3 is easily raised, and the raising property of the sheet bonding portion 11 is more easily maintained.
As shown in fig. 1, 2 nd side, the tip 122 of the sheet edge portion 12 may be formed in a zigzag or wavy shape. Since the tip 122 of the sheet edge portion 12 is zigzag or wavy, a plurality of deformation starting points separated in the 1 st direction X are formed in the tip 122 of the sheet edge portion 12. Therefore, the sheet edge portion 12 is easily restored when deformed, and the sheet edge portion 12 is easily maintained in the raised state. Further, compared with a structure in which the tip 122 of the sheet edge portion 12 is in a straight line shape, the area of the sheet edge portion 12 can be suppressed and the length in the extending direction Z of the sheet edge portion 12 can be ensured. By suppressing the area of the sheet edge portion 12, the area of the outer surface of the container covered by the sheet edge portion 12 can be suppressed, and the deterioration of the appearance can be suppressed. Further, since the sheet edge portion 12 is easily restored even if deformed, local application of force to the absorbent core is suppressed, and the absorption performance is easily maintained. As shown in fig. 1 at the 1 st surface 101, the tip 122 of the sheet edge portion 12 may be linear.
The sheet joint portion 11 may be provided with a display portion for displaying information of the absorbent article 20. The information on the absorbent article includes the product name, brand mark, type (sanitary napkin, disposable diaper), performance (winged, night use), and shape and name of the character of the absorbent article. The display portion of the sheet joining portion 11 attracts the attention of the user, so that the sheet edge portion 12 is made relatively inconspicuous, and the deterioration of the appearance due to the sheet edge portion 12 can be suppressed. The display unit may be formed by printing the storage sheet 10 or by the pressing unit 40. Specifically, the predetermined information (character pattern, character) may be expressed by an aggregate of the plurality of pressing portions 40, or the predetermined information may be expressed by the shape of each pressing portion 40 (character is expressed by the outline of each pressing portion).
In the colored region R3, the color of each pressed portion 40 of the storage sheet may be lighter than the color of the surrounding non-pressed portion (portion that is not pressed). The presence of the pressing portion is easily made noticeable by the difference in color. Therefore, the user can grasp the tightness of the housing body 1 by the presence of the pressing portion, and can obtain a sense of confidence in the sanitary surface, and the display portion can be made conspicuous when the display portion is constituted by the pressing portion 40. In the case where the pressing portion has the high compression portion and the low compression portion, the color of the high compression portion may be lighter than the color of the low compression portion. The presence of the high compression portion is easily made noticeable by the difference in color. Therefore, the display portion, the design, or the sealing property of the housing 1 can be displayed by utilizing the difference between the color of the high compression portion and the color of the low compression portion.
Fig. 6 (a) and 6 (B) are diagrams showing an example in which the sheet joint portion 11 is provided on both the 1 st surface 101 and the 2 nd surface 102. As shown in fig. 6 (a), the sheet bonding portion 11 of the 1 st surface 101 and the sheet bonding portion 11 of the 2 nd surface 102 may be inclined in the same direction with respect to the virtual line FL3 along the 1 st direction X. That is, the sheet joining portions 11 are inclined in the same direction with respect to the virtual line FL3 when the housing body 1 is viewed from one side surface (for example, the 1 st surface 101). The inclination in the same direction may be in a state of non-uniform angle, as long as the inclination direction is the same. For example, in the form shown in fig. 6 (a), the sheet engaging portion 11 of the 1 st surface 101 and the sheet engaging portion 11 of the 2 nd surface 102 are inclined from the 5 th surface 105 side toward the 6 th surface 106 side (from the upper side toward the lower side in fig. 6 (a) and 6 (B)) and from the 3 rd surface 103 side toward the 4 th surface 104 side (from the distal side toward the proximal side in fig. 6 (a) and 6 (B)). If the sheet joined portion 11 of the 1 st surface 101 and the sheet joined portion 11 of the 2 nd surface 102 are inclined in opposite directions, a force in the twisting direction is applied to the absorbent article 20 housed therein, and there is a possibility that the absorbent core may be twisted or partially hardened, resulting in a decrease in the absorption performance. However, since the sheet joint portion 11 of the 1 st surface 101 and the sheet joint portion 11 of the 2 nd surface 102 are inclined in the same direction, the force in the twisting direction is not applied to the absorbent core, and the absorption performance can be ensured.
In the modification, as shown in fig. 6 (B), the sheet joining portion 11 of the 1 st surface 101 and the sheet joining portion 11 of the 2 nd surface 102 may be inclined in opposite directions with respect to the virtual line FL3 along the 1 st direction X. That is, the sheet joint 11 of the 1 st surface 101 and the sheet joint 11 of the 2 nd surface 102 intersect each other when the housing 1 is viewed from one side surface (for example, the 1 st surface 101). For example, in the form shown in fig. 6 (B), the sheet joint 11 of the 1 st surface 101 is inclined from the 5 th surface 105 side toward the 6 th surface 106 side (from the upper side toward the lower side in fig. 6 (a) and 6 (B)) and from the 3 rd surface 103 side toward the 4 th surface 104 side (from the distal side toward the proximal side in fig. 6 (a) and 6 (B)), and the sheet joint 11 of the 2 nd surface 102 is inclined from the 5 th surface 105 side toward the 6 th surface 106 side (from the upper side toward the lower side in fig. 6 (a) and 6 (B)) and from the 4 th surface 104 side toward the 3 rd surface 103 side (from the proximal side toward the distal side in fig. 6 (a) and 6 (B)). According to this embodiment, since the sheet joint portions 11 of the 1 st surface 101 and the sheet joint portions 11 of the 2 nd surface 102 are inclined in opposite directions, the storage body 1 can be stably arranged by the forces that the respective sheet joint portions 11 act and support in mutually different directions. In order to stably arrange the storage body 1, the sheet joint portion 11 of the 1 st surface 101 and the sheet joint portion 11 of the 2 nd surface 102 may not be inclined in the opposite direction as a whole, but may be inclined in the opposite direction at a portion (for example, an amount of 1/3 or more of the length of the sheet joint portion) close to one side of the bottom surface of the storage body.
As shown in fig. 2, z111+z112 > (G11-Z20) can be satisfied when the interval in the extending direction Z between the sheet joined portion 11 of the 1 st surface 101 and the sheet joined portion 11 of the 2 nd surface 102 is G11, the length in the extending direction Z of the absorbent article 20 is Z20, the length in the extending direction Z of the sheet joined portion 11 of the 1 st surface 101 is Z111, and the length in the extending direction Z of the sheet joined portion of the 2 nd surface is Z112. The length Z20 in the extending direction Z of the absorbent article 20 may be the length of the entire absorbent article including the wrapping sheet. (z111+z112) is a region which is relatively high in rigidity and is difficult to deform. On the other hand, (G11-Z20) is a length in which the absorbent article can move in the storage body, and is an area that is easily deformed. Since the length of the region that is liable to be deformed is short, (z111+z112) can suppress misalignment of the absorbent article 20 in the storage body 1 while suppressing misalignment of the storage bodies. If (G11-G20) is short, the absorbent article 20 is less likely to move in the storage body, and the absorbent article 20 is less likely to be damaged. Therefore, the quality of the absorbent article is easily ensured. On the other hand, since (z111+z112) is long, the buffer region is formed in the state where the storage body is disposed in the container (z111+z112), and therefore the absorbent article is less likely to be damaged, and the quality of the absorbent article is likely to be ensured.
The interval G11 in the extending direction Z between the sheet joined portions may be longer than the length Z20 in the extending direction Z of the absorbent article, and the length Z20 in the extending direction Z of the absorbent article 20 may be longer than the length Z21 in the extending direction Z of the main body 21. The absorbent article 20 can be held in the housing body in a state where the package sheet (individual package body) of the absorbent article is not folded. Further, it is preferable that when the length in the extending direction Z of the main body portion 21 in the absorbent article is Z21, z111+z112 > (G11-Z21) can be satisfied. According to this structure, (G11-Z21) functions as a buffer zone, and the quality of the absorbent article can be more easily ensured.
It is possible to satisfy Z111 < (G11-Z20) and Z112 < (G11-Z20). (G11-Z20) is a length of a space in the storage body capable of absorbing the displacement of the absorbent article, and is a relatively easy-to-deform region. Since Z111 (Z112) is shorter than (G11-Z20), deformation of the absorbent article 20 can be suppressed even if the sheet joint portion 11 of the 1 st surface 101 (or the sheet joint portion 11 of the 2 nd surface 102) is pressed toward the inside of the storage body 1.
As shown in fig. 4, in the configuration in which the 1 st region R1 and the 2 nd region R2 are shifted in the 1 st direction, when the shift length in the 1 st direction X of the extension portion 13 is X13, Z111 > X13 and Z112 > X13 can be satisfied. If the length X13 of the offset (extending portion) is longer than the length of the sheet joint portion 11 in the extending direction, the extending portion becomes conspicuous to deteriorate the appearance, and the extending portion 13 may be caught to cause the sheet joint portion to be unintentionally unsealed. However, since Z111 > X13 and Z112 > X13 are satisfied, the width of the sheet joint portion is ensured to be equal to or longer than the length of the extension portion, and thus deterioration in appearance can be suppressed, and unintentional opening of the sheet joint portion 11 can be suppressed. The ratio of X13 to Z111 and the ratio of X13 to Z112 may be less than 1.0, but may be preferably less than 0.5, and more preferably may be less than 0.3. According to this structure, the extension portion 13 is less conspicuous, and the deterioration of the appearance of the storage body can be further suppressed. In addition, when forming the sheet joint portion 11, the extension portion 13 may be subjected to joining processing together with the region where the sheet joint portion 11 is formed. At least two receiving sheets overlap in the region where the sheet joint 11 is formed, but only 1 receiving sheet is arranged in the extending portion 13. Therefore, there is a case where the receiving piece of the extension portion 13 is unintentionally broken due to the bonding process. Therefore, the extension portion may be a portion (not pressed) where the joining process of the receiving piece is not performed.
Next, a package group 100 of absorbent articles (hereinafter, package group 100) will be described with reference to fig. 7. The package group 100 includes a plurality of the above-described storage bodies 1. The housing of the present embodiment includes a 1 st housing 51 and a 2 nd housing 52. The length Z51 of the 1 st housing 51 in the extending direction Z is longer than the length Z52 of the 2 nd housing 52 in the extending direction Z. Further, the length in the 1 st direction X of the 1 st housing 51 may be longer than the length in the 1 st direction X of the 2 nd housing 52, and the length Y51 in the 2 nd direction Y of the 1 st housing 51 may be longer than the length Y52 in the 2 nd direction Y of the 2 nd housing 52. The 1 st length Z511 of the portion of the 1 st housing body 51 obtained by adding the sheet joining portion 11 and the sheet edge portion 12 along the extending direction Z is the same as the 2 nd length Z521 of the portion of the 2 nd housing body 52 obtained by adding the sheet joining portion 11 and the sheet edge portion 12 along the extending direction Z. Here, the 1 st length Z511 and the 2 nd length Z521 are substantially the same length, and the error thereof is within 5% of the length of one. The lengths in the extending direction of the entire storage bodies of the 1 st storage body 51 and the 2 nd storage body 52 are different, but the lengths (1 st length Z511 and 2 nd length Z521) of the portions obtained by adding the sheet joining portion 11 and the sheet edge portion 12 together are the same. The 1 st housing 51 is larger than the 2 nd housing 52, and the proportion of the sheet joint portion 11 and the sheet edge portion 12 is low, thereby improving the appearance. Further, the ratio of the sheet joining portion 11 to the sheet edge portion 12 is different, but since the 1 st length Z511 and the 2 nd length Z512 are the same, the consumer easily recognizes that the package group is the group of the 1 st storage body 51 and the 2 nd storage body 52.
The present invention has been described in detail using the above embodiments, but it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and variations without departing from the spirit and scope of the present invention as defined in the appended claims. Accordingly, the description of the present invention is intended to be illustrative, and not restrictive.
