Problems to be solved by the utility model

Since the absorbent article is circulated in the storage space or carried by a user, the storage body may receive an external force before the absorbent article is used in a circulation process or the like. At this time, if the absorbent article in the storage body is excessively pressed, the absorbent core may locally become hard, and the absorption performance may be impaired or the wearing feeling may be deteriorated. In order to eliminate such a drawback, it is considered that the sheet joint portion is easily opened, and the storage space is opened when the storage body receives an external force, so that the absorbent article is hard to receive the external force. However, if the sheet joint portion is easily opened, the absorbent article may not be kept sanitary.

The present utility model has been made in view of the above problems, and an object of the present utility model is to provide an absorbent article storage body that can keep the absorbent article sanitary and can suppress local deformation of the absorbent article.

Solution for solving the problem

In the absorbent article storage according to one aspect, the absorbent article having the absorbent core is stored in the storage space formed by the storage sheet. The storage body has a sheet engaging portion that engages the storage sheets with each other in a folded state in which the storage sheets are folded into a valley shape. The sheet joining portion has an in-sheet joining portion that joins inner surfaces of the storage sheets to each other to close the storage space, and an out-sheet joining portion that joins the storage sheets of the valley-folded portions of the storage sheets to each other. The joining strength of the in-sheet joining portion is lower than the joining strength of the in-sheet joining portion.

At least the following matters will be apparent from the description of the present specification and the accompanying drawings.

In the absorbent article storage according to one aspect, the absorbent article having the absorbent core is stored in the storage space formed by the storage sheet. The storage body has a sheet engaging portion that engages the storage sheets with each other in a folded state in which the storage sheets are folded into a valley shape. The sheet joining portion has an in-sheet joining portion that joins inner surfaces of the storage sheets to each other to close the storage space, and an out-sheet joining portion that joins the storage sheets of the valley-folded portions of the storage sheets to each other. The joining strength of the in-sheet joining portion is lower than the joining strength of the in-sheet joining portion. When an external force is applied to the storage body, a force is applied to the absorbent article stored therein. The sheet-engaging portion engages the receiving sheets of the valley-shaped folded portion with each other. Therefore, the valley fold portions are opened by the engaged state of the engaging portions being engaged from the engaged state to the disengaged state, and the volume of the storage space of the storage body becomes large. At this time, since the bonding strength of the in-sheet bonding portion is low, the bonded state of the in-sheet bonding portion tends to be released before the in-sheet bonding portion when an external force is applied to the container. The engagement of the engaging portion is released to increase the volume of the storage space while maintaining the engaged state of the engaging portion to maintain the state of closing the storage space. Therefore, when an external force is applied to the storage body, the absorbent article can be stored hygienically while maintaining the sealability of the absorbent article, and local deformation of the absorbent article can be suppressed.

According to a preferred embodiment, the housing has a 1 st surface and a 2 nd surface facing each other in the 1 st direction, and a 3 rd surface and a 4 th surface disposed between the 1 st surface and the 2 nd surface and facing each other in the 2 nd direction. The valley fold portions are provided to both the 3 rd and 4 th faces. The sheet-engaging portion and the valley-shaped folded portion are provided to at least one of the 3 rd surface and the 4 th surface. According to the present utility model, valley-shaped folded portions are provided on both surfaces facing each other across the storage space. The storage volume of the storage space can be made to be appropriately different depending on the opening degree and the closing degree of the valley-shaped folded portion. Further, by adjusting the volume of the storage space in the sheet-bonded portion sandwiching the two surfaces facing each other with the storage space interposed therebetween, local deformation of the absorbent article inside can be suppressed.

According to a preferred embodiment, the in-sheet joint is a welded part formed by welding inner surfaces of the storage sheets to each other, and the in-sheet joint is an adhesive part formed by joining outer surfaces of the storage sheets of the valley-folded portions to each other with an adhesive. According to the present utility model, the bonding method is different between the on-chip bonding portion and the off-chip bonding portion, and therefore the bonding strengths can be easily made different. Further, by forming the off-chip joint portion with an adhesive that can be re-bonded after peeling, the volume of the storage space can be appropriately adjusted, for example, by reducing the storage space after enlarging the storage space once.

According to a preferred embodiment, the in-sheet joint is a welded joint formed by welding inner surfaces of the receiving sheets to each other. The sheet-external engagement portion is a welded portion formed by welding an inner surface of the storage sheet of the 1 st surface and an inner surface of the storage sheet of the 2 nd surface with an opening formed in the storage sheet of the valley-shaped folded portion. According to the present utility model, the intra-chip bonding portion and the inter-chip bonding portion can be obtained by the same bonding method. Further, by making the opening areas of the openings appropriately different, the bonding strength can be appropriately adjusted.

According to a preferred embodiment, the off-chip joint is provided at a position inside the 2 nd direction of the housing body than an outer end edge of the 2 nd direction. According to this aspect, the engagement of the tab-shaped engagement portion is suppressed from being accidentally released when an external force is applied to the outer edge in the 2 nd direction of the housing, and the tab-shaped engagement portion is released when a large external force, which may apply a force to the absorbent article in the housing space, is applied, thereby protecting the absorbent article inside.

According to a preferred embodiment, the in-chip joint portion is formed over the entire area of the storage body in the 2 nd direction. The sheet-engaging portion is formed in a partial region of the storage body in the 2 nd direction. According to the present utility model, since the in-sheet joint is formed over the entire area of the storage body in the 2 nd direction, the absorbent article stored in the interior can be kept sanitary by joining the in-sheet joint over the entire area of the storage body in the 2 nd direction. On the other hand, since the sheet external connection portion is formed in a partial region of the housing in the 2 nd direction, the volume of the housing space is suppressed from being greatly changed by the engagement and non-engagement of the sheet external connection portion, and the user can continue to use without discomfort even when the engagement of the sheet external connection portion is released.

According to a preferred embodiment, the housing has a 3 rd direction orthogonal to the 1 st direction and orthogonal to the 2 nd direction. The in-sheet joint portion is provided at a position inside the 3 rd direction than an outer end edge of the housing body in the 3 rd direction. According to this aspect, the joining of the joining portions in the sheet is suppressed from being accidentally released, and the sanitary absorbent article can be kept inside. Further, since the receiving pieces that are not joined to each other are arranged in a separated state at the outer side in the 3 rd direction than the in-piece joint portion, the receiving pieces can be gripped and the in-piece joint portion can be released, respectively. Therefore, the operation of unsealing the container can be easily performed.

According to a preferred embodiment, the housing has a 3 rd direction orthogonal to the 1 st direction and orthogonal to the 2 nd direction. The in-sheet engagement portion is provided outside the 3 rd direction of the storage space. The in-sheet joint portion is located further to the outside in the 3 rd direction than the in-sheet joint portion. According to the present utility model, when a force is applied from the outer edge of the housing in the 3 rd direction, the engagement is released before the engagement portion in the sheet contacts the engagement portion in the sheet. Therefore, accidental release of the joining portion in the sheet is suppressed, and the absorbent article can be kept sanitary.

According to a preferred embodiment, the housing has a 3 rd direction orthogonal to the 1 st direction and orthogonal to the 2 nd direction. The in-sheet engagement portion is provided outside the 3 rd direction of the storage space. The in-sheet joint is located further outside in the 3 rd direction than the out-sheet joint. According to the present utility model, since the in-sheet joint portion is located further inward in the 3 rd direction than the in-sheet joint portion, the volume of the housing space enclosed by the in-sheet joint portion can be directly increased or decreased by the joining and non-joining of the in-sheet joint portion.

According to a preferred embodiment, at least part of the off-chip joining portion overlaps the on-chip joining portion in the thickness direction of the receiving sheet. According to this aspect, when the joining force of the sheet joining portion is to be released, for example, when the container is opened, the sheet joining portion and the sheet joining portion are easily peeled off at one time. Therefore, the operation of unsealing the container can be easily performed.

According to a preferred embodiment, the bonding strength of the off-chip bonding portion is 1.0N/25mm or more and 20.0N/25mm or less. As a result of intensive studies by the applicant, it was found that the joining strength of the sheet-external joining portion was 1.0N/25mm or more, and the joined state was easily maintained even for external forces normally applied during circulation, and that the joining strength of the sheet-external joining portion was 20.0N/25mm or less, and the joining could be released under strong external forces affecting the absorbent article inside.

According to a preferred embodiment, the off-chip joint is provided on the bottom surface of the housing. According to this aspect, if the folded storage pieces are not joined to each other, there is a case where a space is formed between the folded storage pieces or the folded storage pieces are offset from each other, and it is difficult to stabilize the folded storage pieces when the storage body as the bottom surface is placed. However, since the sheet-engaging portion is formed on the bottom surface, stability when the storage body is placed can be improved.

According to a preferred embodiment, the off-chip joint is provided on the upper surface of the housing. According to the present utility model, if the folded storage pieces are not joined to each other, the following defects may occur: the folded storage tabs are unfolded from each other to deteriorate the appearance, or the folded storage tabs are accidentally hit against the edges of the storage tabs due to the folded storage tabs being unfolded from each other. However, since the sheet-bonded portion is formed on the upper surface, deterioration in appearance and defects due to hitting edges can be suppressed.

According to a preferred embodiment, the receiving sheet has a cutout. The air can be discharged from the storage space to the outside through the slit when the pressure of the storage space is increased. According to this aspect, when a user lifts the storage body, the pressure in the internal space rises, and the air in the storage space is discharged outward through the slit. The volume of the storage space can be adjusted not only by the off-chip joint portion but also by the air coming in and out through the slit.

In the description of the drawings below, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and 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. The storage body 1 stores the absorbent article 20 in the storage space 5 of 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 the storage sheet 10 and joining the storage sheet 10 via the sheet joining portion. The absorbent article 20 is accommodated in the accommodation space 5. The number of the absorbent articles stored in the storage space 5 may be 1 or a plurality. 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 stored in the storage space 5 only in the state of an article (sanitary napkin, disposable diaper, etc.) used at the time of use, or may be stored in the storage space 5 in a state of being individually packaged by an individual packaging sheet (not shown). The housing space 5 of the present embodiment is provided in a central portion of the housing body 1 in the 3 rd direction D3, and on both sides of the housing space 5 in the 3 rd direction D3, an in-chip engaging portion 36 described later is disposed. The storage body 1 has a hole 7 for hanging the storage body on a hook or the like. The hole 7 is an opening formed in the storage piece 10.

The housing 1 has a 1 st direction D1, a 2 nd direction D2, and a 3 rd direction D3 which are orthogonal to each other. In the standing state of the housing body 1 shown in fig. 1, the 1 st direction D1 is a depth direction, the 2 nd direction D2 is a lateral direction extending in the left-right direction, and the 3 rd direction D3 is an up-down direction. The standing state is a state in which characters shown in the storage body and the up-down direction of the design are aligned with the up-down direction in the standing state, and is a state in which the front surface is disposed toward the front side for arrangement of characters or the like of the storage body. In other embodiments, the 1 st direction may be a horizontal direction, the 2 nd direction may be a depth direction, the 3 rd direction may be an up-down direction, in other embodiments, the 1 st direction may be a depth direction, the 2 nd direction may be an up-down direction, and the 3 rd direction may be a horizontal direction, in other embodiments, the 1 st direction may be an up-down direction, the 2 nd direction may be a depth direction, and the 3 rd direction may be a horizontal direction.

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 Yimengda torque tester and EX-0762 were prepared in a constant temperature and humidity chamber (20.+ -. 2 ℃ C., 60.+ -. 5% RH). The load cell was set to 50N for tension and compression and the torque was set to 1N. (2) the samples were cut as shown in Table 1. (3) Jig intervals as shown in table 1 were set such that 50mm×20mm tapes were attached 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. (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) In the measurement, 5 times were performed with different samples, and their average value was used as the bending stiffness value.

The storage sheet 10 may be formed of a resin film and formed into a bag shape. The housing 1 may have 1 st to 4 th surfaces 101 to 104. The 1 st to 4 th surfaces 101 to 104 may be rectangular surfaces, or may intersect in a curved shape instead of perpendicularly intersecting each other at boundaries intersecting each other. The 1 st surface 101 and the 2 nd surface 102 are disposed opposite to each other in the 1 st direction D1, and the 3 rd surface 103 and the 4 th surface 104 are disposed opposite to each other in the 2 nd direction D2. The 1 st and 2 nd faces 101 and 102 may have at least faces extending in the 2 nd and 3 rd directions D2 and D3. The 1 st surface 101 and the 2 nd surface 102 are arranged with a gap in the 1 st direction D1. The 1 st surface 101 forms a front surface in a standing state of the housing 1 shown in fig. 1, and the 2 nd surface 102 forms a rear surface. The 3 rd surface 103 and the 4 th surface 104 may have at least surfaces extending in the 1 st direction D1 and the 3 rd direction D3. The 3 rd surface 103 and the 4 th surface 104 are arranged between the 1 st surface 101 and the 2 nd surface 102, and are arranged with a gap in the 2 nd direction D2. The 3 rd surface 103 and the 4 th surface 104 constitute side surfaces of the housing body 1 in a standing state. The storage body 1 is constituted by a so-called gusset bag, and the 3 rd surface 103 and the 4 th surface 104 are valley-folded toward the inside in the 2 nd direction D2. That is, the valley-shaped folded portions are provided on the 3 rd surface 103 and the 4 th surface 104.

The housing body 1 has a 5 th surface 105 and a 6 th surface 106, and the 5 th surface 105 and the 6 th surface 106 are provided with the housing pieces 10 extending outward in the 3 rd direction D3 from the 1 st surface 101 to the 4 th surface 104, respectively. The 5 th surface 105 and the 6 th surface 106 are arranged with a space in the 3 rd direction D3. The 5 th surface 105 is located on one side of the 3 rd direction D3 with respect to the 1 st surface 101 to the 4 th surface 104, and the 6 th surface 106 is located on the other side of the 3 rd direction D3 with respect to the 1 st surface 101 to the 4 th surface 104. In the present embodiment, the 5 th surface 105 forms the bottom surface of the housing body 1, and the 6 th surface 106 forms the upper surface of the housing body 1.

The sheet joining portion joins the storage sheets 10 to each other in a folded state in which the storage sheets 10 are folded into a valley shape. Fig. 2 is a view showing a folded state of the storage sheet before the sheet joining portion is formed. The storage sheet of the 3 rd surface 103 and the storage sheet of the 4 th surface are formed with valley-folded portions 50, and the valley-folded portions 50 are valley-folded inward in the 2 nd direction D2 starting from an apex 51 located near the center in the 1 st direction D1. Fig. 3 (a) to (d) are cross-sectional views of the housing shown in fig. 1. Fig. 3 (a) is a sectional view taken along the line A-A shown in fig. 1, fig. 3 (B) is a sectional view taken along the line B-B shown in fig. 1, fig. 3 (C) is a sectional view taken along the line C-C shown in fig. 1, and fig. 3 (D) is a sectional view taken along the line D-D shown in fig. 1. As shown in fig. 3 (a), in the folded state in which the storage sheet 10 is folded into the valley shape, 4 layers of the storage sheet 10 are arranged in such a manner that the valley-shaped folded portions of the 1 st surface 101, the 3 rd surface 103 (or the valley-shaped folded portion of the 4 th surface 104) and the 2 nd surface 102 overlap each other on the storage side portion 1S as the outer end portion in the 2 nd direction D2 of the storage body 1. In the folded state, only two storage sheets 10 are arranged in the storage center portion 1C (the inner portion in the 2 nd direction D2 with respect to the valley-shaped folded portion) which is the center in the 2 nd direction D2 of the storage body 1, with the 1 st surface 101 overlapping the 2 nd surface 102. The sheet joining portion has an in-sheet joining portion 36 that joins the inner surfaces 11 of the storage sheets 10 to each other and closes the storage space 5, and an out-sheet joining portion 37 that joins the storage sheets 10 of the valley-folded portions of the storage sheets 10 to each other.

The intra-sheet joint 36 defines a storage space 5 in which the absorbent article 20 is stored. The receiving space 5 is opened by releasing the in-sheet engagement portion 36. The in-sheet engagement portion 36 may extend in the 2 nd direction D2. The intra-sheet engaging portion 36 may have an 1 st inner engaging portion 31 that engages the inner surface 11 of the receiving sheet 10 of the 1 st face 101 and the inner surface 11 of the receiving sheet 10 of the 2 nd face 102, a 2 nd inner engaging portion 32 that engages the inner surface 11 of the receiving sheet 10 of the 2 nd face 102 and the inner surface 11 of the receiving sheet 10 of the 3 rd face 103, a 3 rd inner engaging portion 33 that engages the inner surface 11 of the receiving sheet 10 of the 1 st face 101 and the inner surface 11 of the receiving sheet 10 of the 3 rd face 103, a 4 th inner engaging portion 34 that engages the inner surface 11 of the receiving sheet 10 of the 1 st face 101 and the inner surface 10 of the receiving sheet 10 of the 4 th face 104, and a 5 th inner engaging portion 35 that engages the inner surface 11 of the receiving sheet 10 of the 2 nd face 102 and the inner surface 11 of the receiving sheet 10 of the 4 th face 104. In the mode in which the valley-folded portions of the 3 rd surface 103 and the valley-folded portions of the 4 th surface 104 are partially formed, the 1 st inner joint portion 31, which joins the 1 st surface 101 and the 2 nd surface 102, may be formed over the entire region of the storage body in the 2 nd direction D2, and the storage space 5 may be closed only by the 1 st inner joint portion 31, with respect to the intra-sheet joint portion 36. The in-sheet engagement portions 36 of the present embodiment are provided on both outer sides of the storage space 5 in the 3 rd direction D3. However, in the modification, the storage sheet 10 may be continuous on one side of the storage space 5 in the 3 rd direction, and the in-sheet engaging portion 36 may be provided only on the other side of the storage space 5 in the 3 rd direction D3.

The sheet external engagement portion 37 engages the valley-shaped folded portion of the storage sheet 10. The sheet-external bonding portion 37 may have a 3 rd external bonding portion 38 that bonds the valley-folded portion of the 3 rd surface 103 and a 4 th external bonding portion 39 that bonds the valley-folded portion of the 4 th surface 104. In the present embodiment, the valley-shaped folded portions are provided on both the 3 rd surface 103 and the 4 th surface 104, but in a modification, the valley-shaped folded portions may be provided on only either the 3 rd surface 103 or the 4 th surface 104. The valley-shaped folded portion may be provided on a surface other than the 3 rd surface 103 and the 4 th surface 104, and the sheet-bonding portion 37 may be provided on a surface other than the 3 rd surface 103 and the 4 th surface 104. The off-sheet joining portion 37 may join the valley-folded portions directly to each other by an adhesive or the like, or may join the valley-folded portions indirectly by forming an opening in the receiving sheet constituting the valley-folded portion and joining other portions of the receiving sheet through the opening.

The storage body 1 of the present embodiment is configured to be able to suppress local deformation of the absorbent article 20 while keeping the absorbent article 20 sanitary. Next, a structure for suppressing local deformation of the absorbent article 20 while keeping the absorbent article 20 sanitary will be described in detail. The bonding strength of the in-sheet bonding portion 37 may be lower than that of the in-sheet bonding portion 36. In the structure in which the plurality of the in-sheet joint portions 37 are formed, the lowest joining strength in the in-sheet joint portions 37 may be lower than the joining strength of any one of the in-sheet joint portions 36. More preferably, the highest bonding strength in the in-sheet bonding portion 37 is lower than the bonding strength of all the in-sheet bonding portions 36. In addition, the bonding strength can be measured as follows. (1) The measurement sample was extracted with the joint of the measurement object at the center, and the length was 100mm×width was 15 mm. (2) An aluminum tape having a dimension of 50mm×25mm was attached to both ends of the measurement sample in the longitudinal direction so that the jig interval became 50mm, and grip portions were formed at both ends of the measurement sample in the measurement direction. (3) The measurement sample was mounted on a jig, and its maximum torque value was measured at a tensile speed of 500 mm/min. (4) In the measurement, 5 times were performed with different samples, and their average value was used as the bonding strength.

When an external force is applied to the storage body 1, a force is applied to the absorbent article 20 stored therein. The off-sheet engaging portion 37 engages the valley-shaped folded portion 50. Therefore, the valley fold portions 50 are opened by the engaged state of the engaging and disengaging from the engaging and disengaging state of the sheet outer engaging portions 37, and the volume of the housing space 5 of the housing body 1 becomes large. At this time, since the bonding strength of the in-sheet bonding portion 37 is low, the bonded state of the in-sheet bonding portion 37 tends to be released before the in-sheet bonding portion 36 when an external force is applied to the housing body 1. The engagement of the sheet outer engagement portion 37 can be released to increase the volume of the storage space 5 while maintaining the engaged state of the sheet inner engagement portion 36 to maintain the state of closing the storage space 5. Therefore, when an external force is applied to the storage body 1, the absorbent article 20 can be stored hygienically while maintaining the sealability of the absorbent article 20, and local deformation of the absorbent article 20 can be suppressed.

The valley-shaped folded portion 50 is provided on both the 3 rd surface 103 and the 4 th surface 104, and the sheet-bonded portion 37 may be provided on at least either one of the 3 rd surface 103 and the 4 th surface 104. According to the present embodiment, valley-shaped folded portions are provided on both surfaces facing each other across the storage space 5. The volume of the storage space 5 can be made to be appropriately different depending on the opening degree and the closing degree of the valley-shaped folded portion. Further, by adjusting the volume of the storage space 5 in the off-chip joint 37 of the two surfaces facing each other across the storage space 5, it is possible to suppress local deformation of the absorbent article 20.

The intra-sheet joint 36 may be a welded part obtained by welding the inner surfaces 11 of the storage sheets 10 to each other, and the outer-sheet joint 37 may be an adhesive part obtained by joining the outer surfaces 12 of the storage sheets 10 of the valley-folded portions to each other with an adhesive. Specifically, the 1 st inner joint 31, the 2 nd inner joint 32, the 3 rd inner joint 33, the 4 th inner joint 34, and the 5 th inner joint 35 are fusion welds, and the 3 rd outer joint 38 and the 4 th outer joint 39 are adhesive bonds. According to this aspect, the bonding method is different between the in-chip bonding portion 36 and the in-chip bonding portion 37, and thus the bonding strengths can be easily made different. Further, by configuring the off-chip joining portion 37 with an adhesive that can be re-bonded after peeling, the volume of the storage space 5 can be appropriately adjusted by, for example, reducing the storage space 5 once the storage space 5 is enlarged.

The welded portion may be a welded portion such as a thermal welded portion or an ultrasonic welded portion. The storage sheet (for example, the inner surface) is provided with a layer (polyethylene layer) that can be welded under relatively low temperature or low energy conditions, such as a layer made of thermoplastic resin. For comparison of the temperatures, the welding temperature of the inner surface layer may be lower than the welding temperature of the outer surface layer. The storage sheet 10 may have at least a layer that can be welded under relatively low temperature conditions, and may be a laminate sheet formed by stacking other layers. In order to provide the intra-sheet joint portion and the inter-sheet joint portion according to embodiment 1, the inner surface of the receiving sheet may be formed of a layer capable of being welded, and the outer surface of the receiving sheet may be formed of a layer capable of being welded or a layer (for example, a layer made of a non-thermoplastic resin) capable of being welded under a condition higher in temperature or higher in energy than the layer on the inner surface. With this storage sheet, the welding process is performed over the entire region in the 2 nd direction D2 of the storage body 1 in a state where the valley-shaped folded portion is formed, whereby only the portions of the inner surfaces 11 of the storage sheet 10 facing each other are welded to form the in-sheet joint portion 36. However, in the region where the outer surfaces 12 of the receiving sheet 10 in the valley-folded portion face each other, it is difficult to weld by the welding process. By providing an adhesive portion for adhering the valley-shaped folded portions after the fusion process, the container 1 of embodiment 1 can be obtained. Further, polypropylene may be disposed as a layer constituting the outer surface of the receiving sheet. By printing with the polypropylene layer, the designability of the storage sheet can be improved.

The sheet-external engagement portion 37 may be provided at a position further inward in the 2 nd direction D2 than the outer end edge of the 2 nd direction D2 of the housing body 1. More specifically, as shown in fig. 3 (b), the outer edge 37E in the 2 nd direction D2 of the sheet-external joint portion 37 is located inside the 2 nd direction D2 than the outer edge in the 2 nd direction D2 of the 3 rd surface 103. The sheet-bonding portion 37 may be provided over the entire region in the 2 nd direction D2 of the valley-folded portion, or may be located further inward in the 2 nd direction D2 than the outer edge of the 2 nd direction D2 of the valley-folded portion (in the present embodiment, the outer edge in the 2 nd direction of the 3 rd surface). If the sheet external engagement portion 37 is provided at the outer edge of the 2 nd direction D2 of the housing body 1, the engagement of the sheet external engagement portion 37 may be accidentally released when an external force is applied to the outer edge of the 2 nd direction D2 of the housing body 1. However, since the sheet-bonded portion 37 is provided at a position further inward in the 2 nd direction D2 than the outer edge of the 2 nd direction D2 of the housing body 1, the sheet-bonded portion 37 is prevented from being accidentally released when an external force is applied to the outer edge of the 2 nd direction D2 of the housing body 1, and the sheet-bonded portion 37 is released when a large external force, which may be applied to the absorbent article 20 in the housing space 5, is applied, so that the inner absorbent article 20 can be protected.

The in-sheet joint 36 may be formed over the entire region of the housing 1 in the 2 nd direction D2, and the in-sheet joint 37 may be formed over a partial region of the housing in the 2 nd direction. Here, the entire area of the storage body 1 in the 2 nd direction D2 may be an area that encloses the storage space 5. According to the present embodiment, since the in-sheet joint portion 36 is formed over the entire region in the 2 nd direction D2 of the storage body 1, the absorbent article 20 stored therein can be kept sanitary by joining the in-sheet joint portion 36 over the entire region in the 2 nd direction D2 of the storage body 1. On the other hand, since the sheet external connection portion 37 is formed in a partial region of the housing body 1 in the 2 nd direction D2, the volume of the housing space 5 is suppressed from greatly changing due to the engagement and non-engagement of the sheet external connection portion 37, and the user can continue to use without discomfort even when the engagement of the sheet external connection portion 37 is released.

The in-sheet engagement portion 36 may be provided at a position inside the 3 rd direction D3 than the outer end edge of the 3 rd direction D3 of the housing body 1. It is particularly preferable that the upper surface of the storage body 1 is provided at a position inside the 3 rd direction D3 than the outer edge of the storage piece 10 constituting the outer edge of the 3 rd direction D3 of the storage body 1. If the in-sheet engagement portion 36 is provided at the outer end edge of the storage body 1 in the 3 rd direction D3, the engagement of the in-sheet engagement portion 36 may be accidentally released when an external force is applied to the outer end edge of the storage body 1 in the 3 rd direction D3. However, since the in-sheet joining portion 36 is provided at a position inside the 3 rd direction D3 than the outer end edge of the 3 rd direction D3 of the storage body 1, the joining of the in-sheet joining portion 36 is suppressed from being accidentally released, and the sanitary condition of the absorbent article 20 inside can be maintained. Further, since the storage sheets 10 that are not joined to each other are disposed in a separated state at positions outside the in the 3 rd direction D3 than the in-sheet joint portion 36, the in-sheet joint portion 36 can be released by holding the storage sheets 10, respectively. Therefore, the operation of unsealing the container 1 can be easily performed. Similarly, the sheet-external engagement portion 37 may be provided on the inner side of the outer end edge of the housing 1 in the 3 rd direction D3. It is possible to suppress the unexpected release of the engagement of the off-chip engagement portion 37.

The in-sheet joint portion 36 may be provided outside the 3 rd direction D3 of the storage space 5, and the in-sheet joint portion 37 may be positioned outside the in-sheet joint portion 36 in the 3 rd direction D3. When a force is applied from the outer edge of the housing 1 in the 3 rd direction D3, the engagement of the sheet-engaging portion 37 is released before the sheet-engaging portion 36 hits the sheet-engaging portion 37. Therefore, accidental release of the in-sheet joint 36 is suppressed, and the absorbent article 20 can be kept sanitary. The sheet-engaging portion 37 may be provided in the storage sheet 10 at a position separated from the region surrounding the storage space 5 without overlapping the region surrounding the storage space 5. According to this structure, the storage sheet 10 surrounding the area of the storage space 5 is not directly deformed by the engagement and non-engagement of the off-sheet engagement portion 37, but the volume of the storage space is indirectly changed by the deformation of the storage sheet 10 in the area other than the area surrounding the storage space 5. Therefore, the deformation of the absorbent article 20 can be suppressed by suppressing the extreme change in the volume of the storage space 5.

In the modification, the in-sheet joint 36 may be provided outside the 3 rd direction D3 of the storage space 5, and the in-sheet joint 36 may be located outside the in-sheet joint 37 in the 3 rd direction D3. That is, the sheet-external engagement portion 37 may overlap with the region surrounding the storage space 5 in the storage sheet 10. According to this structure, since the in-sheet joint portion 37 is located further inward in the 3 rd direction D3 than the in-sheet joint portion 36, the volume of the storage space 5 closed by the in-sheet joint portion 36 can be directly increased or decreased by the joining and non-joining of the in-sheet joint portion 37.

At least part of the sheet external engagement portion 37 may overlap with the sheet internal engagement portion 36 in the thickness direction of the storage sheet 10. According to this embodiment, when a force to release the engagement of the sheet engagement portions is applied, for example, when the container 1 is opened, the sheet engagement portions 37 and the sheet engagement portions 36 are easily peeled off at a time. Therefore, the operation of unsealing the container 1 can be easily performed. In the modification, the sheet external bonding portion 37 may be disposed only in a region that does not overlap with the sheet internal bonding portion 36 in the thickness direction of the storage sheet 10.

The joining strength of the sheet external joining portion 37 may be lower than that of the sheet internal joining portion 36, but is preferably 1.0N/25mm or more and 20.0N/25mm or less. As a result of intensive studies by the applicant, it was found that the joining strength of the sheet-external joining portion 37 was 1.0N/25mm or more, and the joined state was easily maintained even for external forces normally applied during circulation, and that the joining strength of the sheet-external joining portion 37 was 20.0N/25mm or less, and that joining could be released under strong external forces that affect the absorbent article 20 inside.

The sheet external engagement portion 37 may be provided on the bottom surface of the housing body 1. In the present embodiment, the 5 th surface 105 is provided with the external sheet joint portion 37. If the folded storage sheets 10 are not joined to each other, there are cases where a space is formed between the folded storage sheets 10 or the folded storage sheets 10 are offset, and it is difficult to stabilize when the storage body 1 as the bottom surface is placed. However, since the sheet external engagement portion 37 is formed on the bottom surface, stability when the storage body 1 is placed can be improved.

The sheet external engagement portion 37 may be provided on the upper surface of the housing body 1. In the present embodiment, the 6 th surface 106 is provided with the off-chip bonding portion 37. If the folded storage sheets 10 are not joined to each other, the following defects may occur: the folded storage tabs are unfolded from each other to deteriorate the external appearance or accidentally hit the edges of the storage tabs 10 due to the folded storage tabs 10 being unfolded from each other. However, since the sheet external engagement portion 37 is formed on the upper surface, deterioration in appearance and defects due to hitting edges can be suppressed.

Next, a storage body 1X according to embodiment 2 will be described with reference to fig. 4 (a) and (b). Fig. 4 (a) is a cross-sectional view based on the line A-A shown in fig. 1, and fig. 4 (b) is a cross-sectional view based on the line D-D shown in fig. 1. In the description of embodiment 2, the same components as those of embodiment 1 are given the same reference numerals, and the description thereof is omitted. The in-sheet joint portion 37 and the in-sheet joint portion 36 of embodiment 2 are each constituted by a welded portion. The in-sheet joint portion 37 is provided in a region overlapping with the in-sheet joint portion 36, and is formed together (simultaneously) with the in-sheet joint portion 36 in the manufacturing process. A plurality of openings 15 are formed in the receiving sheet 10 of the valley-folded portion. The plurality of openings 15 are formed to penetrate the storage sheet 10 at intervals. The size of the opening may be 1.0mm or more and 5.0mm or less.

The in-sheet joint 36 of embodiment 2 is a welded part obtained by joining the inner surfaces 11 of the storage sheets 10 to each other by welding, and the in-sheet joint 37 is a welded part obtained by joining the inner surfaces 11 of the storage sheets 10 of the 1 st surface 101 and the inner surfaces 11 of the storage sheets 10 of the 2 nd surface 102 by welding through the openings of the valley-shaped folded portions. In the housing side portion 1S of the housing body 1, an external sheet joint portion 37 is formed in a region where the opening 15 is formed, and an internal sheet joint portion 36 is formed in a region where the opening 15 is not formed. In this embodiment, the sheet-external engagement portion 37 engages the storage sheet 10 of the valley-folded portion with the inner surface 11 of the 1 st surface 101 and the inner surface 11 of the 2 nd surface 102 by sandwiching the storage sheet. Focusing on the 1 st surface 101 and the 2 nd surface 102, the in-chip bonding portion 37 also has the function of the in-chip bonding portion 36. Since the openings 15 are formed in the valley-folded portions, if the entire region of the 2 nd direction D2 of the storage body 1 can be welded in a state in which the valley-folded portions are formed, the portions of the inner surfaces 11 of the storage sheet 10 facing each other can be welded together, and the intra-sheet joint portions 36 and the inter-sheet joint portions 37 can be formed together, so that the storage body 1X of embodiment 2 can be obtained. That is, the intra-chip bonding portion 36 and the inter-chip bonding portion 37 can be obtained by the same bonding method. Further, by making the opening area of the opening 15 appropriately different, the bonding strength can be appropriately adjusted

The present utility model has been described in detail with reference to the above embodiments, but it is clear to those skilled in the art that the present utility model is not limited to the embodiments described in the present specification. The present utility model can be implemented as modifications and variations without departing from the spirit and scope of the present utility model as defined in the appended claims. Accordingly, the description of the present utility model is intended to be illustrative, and not limiting.

The area of the in-sheet joint may be larger than the area of the in-sheet joint. Further, the in-sheet joint portion 36 and the in-sheet joint portion 37 may each be constituted by an adhesive portion with an adhesive. In this modification, the type of adhesive of the in-sheet joint portion 36 may be made different from the type of adhesive of the in-sheet joint portion 37. The in-sheet joint portion and the out-sheet joint portion may both extend in the 2 nd direction D2, may both extend in the 3 rd direction D3, or may extend in the 3 rd direction D3 while the other extends in the 2 nd direction D2.

The storage sheet 10 may have a slit 40, and may be configured to be able to discharge air from the storage space 5 to the outside through the slit 40 when the pressure of the storage space 5 is increased. The notch 40 may be a hole formed at a position separated from the in-sheet joint 36 and the out-sheet joint 37 as shown in fig. 1, or may be a portion formed by the opening 15 of the storage sheet 10 formed in the valley-folded portion of embodiment 2 shown in fig. 3 (a) to (d) and the inner surfaces of the storage sheets are not joined to each other by the opening 15. The cutout 40 may be provided in the storage sheet 10 in a region surrounding the storage space 5. With such a storage body, when a user lifts the storage body, for example, the pressure in the internal space rises, and the air in the storage space 5 is discharged outside through the slit. Not only the volume of the storage space 5 is adjusted by the off-chip joint 37, but also the volume of the storage space 5 can be adjusted by the air coming in and out through the slit 40.

The notch 40 of embodiment 1 shown in fig. 1 may be provided on at least any one of the 1 st to 4 th surfaces 101 to 104, but is preferably provided on each of the 1 st to 4 th surfaces 101 to 104. The slit 40 of the present embodiment is provided in two on each of the 1 st to 4 th surfaces 101 to 104. The slit 40 has a width of 2mm in the lateral direction, and penetrates the 1 st to 4 th surfaces 101 to 104 of the storage sheet 10. The distance between adjacent slits 40 in the lateral direction was 2mm. In the present embodiment, a total of 8 cutouts 40 are provided in the storage sheet 10, but the shape, number, and arrangement of the cutouts 40 are not limited thereto. The maximum dimension of the cutout 40 may also be greater than the maximum dimension of the aperture 15.
