(First embodiment)
With reference to FIGS. 1-3, the package of the absorbent article which concerns on the 1st Embodiment of this invention is demonstrated. FIG. 1 is a plan view of a package for absorbent articles, and FIG. 2 is a rear view of the package for absorbent articles. 3 is a schematic cross-sectional view taken along the line AA shown in FIG. The absorbent article packaging body 100 includes an absorbent article 1 and a packaging sheet 70 for packaging the absorbent article 1. The absorbent article 1 according to the present embodiment is, for example, a sanitary napkin.

  The absorbent article 1 is individually wrapped in the package 100 of the absorbent article by folding the packaging sheet 70 and the absorbent article 1 in a state where the absorbent article 1 is disposed on the packaging sheet 70. 1 and 2 show a state in which the absorbent article 1 is opened after individually packaging the absorbent article 1 with the packaging sheet 70.

  The absorbent article 1 includes a top sheet 10 that comes into contact with the wearer's skin, a liquid-impermeable back sheet 20 that does not transmit liquid, and an absorber 30. The absorber 30 is disposed between the top sheet 10 and the back sheet 20. Therefore, the absorber 30 is shown with a broken line in FIG. The absorbent body 30 is disposed at the central portion in the longitudinal direction L and the width direction W of the absorbent article 1. In addition, the absorbent article 1 includes wing portions 43 and 44 provided outside the absorbent body 30 in the width direction W orthogonal to the longitudinal direction L in the plan view shown in FIG. Furthermore, the absorbent article 1 includes side sheets 41 and 42 provided outside the absorber 30 in the width direction W.

  The top sheet 10 is a liquid-permeable sheet that transmits liquid such as body fluid. The top sheet 10 covers at least the surface of the absorber 30. The top sheet 10 is not particularly limited as long as it is a sheet-like material having a structure that allows liquid to permeate, such as a nonwoven fabric, a woven fabric, a perforated plastic sheet, and a mesh sheet. Either natural fibers or chemical fibers can be used as the woven or non-woven material. The topsheet 10 of the present embodiment is an air-through nonwoven fabric. The core of the fiber is polyethylene terephthalate, the sheath is 2.2 dtex of polyethylene, and the fiber length is 51 mm. A hydrophilic oil agent is applied to the surface of the fiber. The physical properties of the surface sheet are preferably such that the 5% elongation strength in the intersecting direction intersecting the conveying direction of the absorbent article in the manufacturing process of the absorbent article is 0.6 N / 25 mm or less, and 5 in the CD direction. It is more preferable that the% elongation strength is 0.3 N / 25 mm or less.

  The back sheet 20 has substantially the same length as that of the top sheet 10. The back sheet 20 may be a film mainly composed of polyethylene, polypropylene, or the like, a breathable resin film, a sheet obtained by bonding a breathable resin film to a nonwoven fabric such as spunbond or spunlace. The back sheet 20 is preferably made of a material having flexibility that does not cause a sense of incongruity when worn. The back sheet 20 of the present embodiment is constituted by a liquid-impermeable polyethylene film.

  The absorber 30 includes hydrophilic fibers and pulp. The absorber 30 includes a lower layer absorber 31 and an upper layer absorber 32 stacked on the lower layer absorber 31. The upper layer absorber 32 is smaller than the lower layer absorber 31 in the longitudinal direction L and the width direction W. In addition, the lower layer absorber 31 and the upper layer absorber 32 may be comprised separately, and may be integrated. Moreover, the lower layer absorber 31 and the upper layer absorber 32 are bonded together by a hot melt adhesive.

The absorber 30 including the lower layer absorber 31 and the upper layer absorber 32 is formed of a material that can absorb body fluid such as menstrual blood. The absorbent body 30 may be formed by laminating hydrophilic fibers or powder by the airlaid method, an airlaid sheet obtained by forming hydrophilic fibers or powder into a sheet shape by the airlaid method, or a tissue (for example, It may be formed by placing pulverized pulp mixed with a superabsorbent polymer on a basis weight of 15 g / m ² ) and wrapping it with a tissue.

  The top sheet 10 is embossed in a pin shape having a diameter of 2 mm. The embossing may be a hinge-like embossing as conventionally used. Moreover, the surface sheet 10 and the absorber 3 are joined by a hot melt adhesive.

The side sheets 41 and 42 are sheet materials that cover the outer side in the width direction of the absorbent article, and are disposed on both sides of the top sheet 10. The side sheets 41 and 42 can be selected from the same material as the top sheet 10. However, in order to prevent menstrual blood from flowing over the side sheets 41 and 42 to the outside of the absorbent article 1, it is preferable to have hydrophobicity or water repellency. The side sheets 41 and 42 of the present embodiment are spunbonded nonwoven fabrics having a basis weight of 22 g / m ² . For example, the fiber core is polypropylene and the sheath is polyethylene.

  The side sheets 41 and 42 cover a part of the side edge of the absorber 30 and the wing parts 43 and 44. An inner end 41E in the width direction of the side seat 41 is disposed adjacent to the first longitudinal fold FL1 on the outer side in the width direction than a first longitudinal fold FL1 described later. The inner end portion 42E in the width direction of the side seat 42 is disposed adjacent to the second longitudinal fold FL2 on the outer side in the width direction than a second longitudinal fold FL2 described later.

  In the absorbent article 1, the periphery of the surface sheet 10, the side sheets 41 and 42, and the back sheet 20 is joined, and the absorber 30 is enclosed. As a method for joining the top sheet 10 and the back sheet 20, any one or a combination of heat embossing, ultrasonic waves, or hot melt adhesive can be used.

  In the back sheet 20, the adhesive 50 is applied to the surface in contact with the undergarment in a plurality of regions (see FIG. 2). The adhesive 50 is intermittently disposed along the longitudinal direction L of the back sheet 20. The adhesive 50 is also provided on the surface in contact with the undergarment in the wing portion 43 and the wing portion 44. In the state before use, the adhesive 50 is in contact with the packaging sheet 70, and the packaging sheet 70 prevents the adhesive from deteriorating before use. And the packaging sheet 70 is peeled by the wearer at the time of use. In addition, you may comprise so that it may prevent that an adhesive agent deteriorates before use with protective sheets consisting of papers other than the packaging sheet 70. FIG. As the adhesive, for example, a hot melt adhesive can be used.

  The packaging sheet 70 packages the absorbent article 1 individually. The packaging sheet 70 has a facing surface 71 that faces the absorbent article 1 on the back sheet 20 side of the absorbent article 1 and a non-facing surface 72 that is positioned outside in a state in which the absorbent article 1 is accommodated.

  Note that the packaging sheet 70 may be subjected to surface processing such as round dot embossing or satin embossing on the surface of the packaging sheet 70 for the purpose of improving the texture or the like. Examples of the material of the packaging sheet 70 include various films such as plastic films such as polyethylene, polypropylene, and polyester, nylon films, a breathable film stretched with a filler such as barium sulfate, and a film laminated with a nonwoven fabric. Can be mentioned. Furthermore, the surface of the packaging sheet 70 is subjected to a treatment that allows the surface to be peeled without reducing the adhesive strength of the adhesive.

  The absorbent article 1 and the packaging sheet 70 are folded at a predetermined folding position along the width direction W and the longitudinal direction L with the surface sheet 10 of the absorbent article 1 inside. In a state where the absorbent article 1 is folded, one end portion in the longitudinal direction L of the packaging sheet 70 is adhered to the packaging sheet 70. The edge part of the packaging sheet 70 is stuck to a part of the packaging sheet 70 by the adhesive tape 75.

  Next, a method for folding the absorbent article package 100 will be described. 4 to 6 are perspective views schematically showing a folding process of the package 100 of absorbent articles. The folding process of the absorbent article packaging body 100 includes an absorbent article placing process, a first folding process, a second folding process, a joining process, and a third folding process.

  In the absorbent article placement step, the absorbent article 1 is disposed on the packaging sheet 70. The packaging sheet 70 and the back sheet 20 of the absorbent article 1 face each other. In addition, you may arrange | position the absorbent article 1 on the packaging sheet 70 of the dimension which wraps one absorbent article 1 separately, for example, a predetermined space | interval is provided on the packaging sheet continuous along a conveyance direction. You may comprise so that several absorbent articles may be arrange | positioned emptying. In the present embodiment, for convenience of explanation, a folding method will be described using a package of absorbent articles for packaging one absorbent article.

  In the first folding step, as shown in FIG. 4, the packaging sheet 70 and the absorbent article 1 are along the longitudinal direction L from the end region side including one end side of the absorbent article 1 in the width direction. The first longitudinal fold line (see FIG. 1) is folded back inward from the base point FL1. In the second folding step, as shown in FIG. 5, the packaging sheet 70 and the absorbent article 1 are moved in the longitudinal direction L from the end region side including the other end side of the absorbent article 1 in the width direction W. The second width fold line FL2 (see FIG. 1) along the line is folded back inward.

  Next, in the joining step, the absorbent article 1 and the end portion in the width direction of the packaging sheet 70 which are folded back with the second longitudinal fold line FL2 as the base point are adhered to the packaging sheet 70 by the adhesive 50. By this step, the absorbent article 1 is individually packaged by the packaging sheet 70. In the present embodiment, the widthwise ends of the packaging sheet 70 folded back from the first longitudinal fold FL1 and the second longitudinal fold FL2 are bonded by the adhesive 50, but the width of the packaging sheet 70 It is not necessary to bond the end portions in the direction. Moreover, you may adhere | attach the bonding method of the width direction edge part of the packaging sheet 70 by heat welding, crimping | compression-bonding, or ultrasonic welding.

  In the third folding step, as shown in FIG. 6, the packaging sheet 70 and the absorbent article 1 are separated from both ends in the longitudinal direction L of the absorbent article 1 by the first width fold FW1 along the width direction W. Folded inward from the second width fold FW2 (see FIG. 1). By performing the above-described steps, the absorbent article packaging body 100 is folded and miniaturized.

  By folding in this way, the absorbent article 1 can be compactly packaged by the packaging sheet 70. Specifically, the absorbent article and the packaging sheet can be reduced to about 1/9 compared with the case where the planar area of the absorbent article and the packaging sheet is expanded, so that the absorbent article can be made compact. By reducing the size of the absorbent article 1, when storing it in a bag such as an accessory case or a pochette, it does not occupy a large space for storing the bag, and can be easily carried. Further, by packing the absorbent article 1 in a compact manner, it can be placed in the hand even when it is not folded when being carried in a toilet or the like during use, and can be kept from being seen by others.

  Further, the first longitudinal fold FL1 and the second longitudinal fold FL2 in the state in which the package 100 of the absorbent article folded in this way is opened are on the outer side in the width direction of the absorbent body 30, and from the side sheets 41 and 42. Is also located on the inner side in the width direction. As shown in FIG. 3, the first longitudinal crease FL1 and the second longitudinal crease FL2 are formed in a region where the top sheet 10 and the back sheet 20 overlap. The first longitudinal crease FL1 and the second longitudinal crease FL2 do not overlap the absorber 30 and the side sheets 41 and 42 in the thickness direction T. Accordingly, the crease caused by the first longitudinal fold FL1 and the second longitudinal crease FL2 is formed only on the top sheet 10 and the back sheet 20. In general, the top sheet 10 and the back sheet 20 have lower rigidity than the absorber 30. No creases remain on the top sheet 10 and the back sheet 20. Note that the rigidity in the present specification means the degree to which an object resists deformation when an external force is applied to the object to cause deformation. For example, the higher the rigidity, the greater the resistance to deformation and the stronger the crease when folded.

  Therefore, it is difficult for folds in the longitudinal direction to remain, and when the absorbent article 1 is attached to the underwear, the absorbent article 1 can be prevented from floating from the underwear due to the fold. Furthermore, it is possible to prevent a problem that it is difficult for the absorbent article to expand outward in the width direction due to a crease extending in the longitudinal direction. The wearer can easily place the absorbent article along the inner surface of the undergarment, or can easily fold the wing portion on the non-contact surface side of the undergarment to improve wearability. Can do.

  In addition, side sheets 41 and 42 are provided on the outer sides in the width direction of the first longitudinal folds FL1 and the second longitudinal folds FL2, and have rigidity in the outer side in the width direction than the first longitudinal folds FL1 and the second longitudinal folds FL2. Highly structured. Therefore, the packaging body of the absorbent article is caused by the difference in rigidity between the portion where the first longitudinal fold FL1 and the second longitudinal fold FL2 are formed and the portion outside in the width direction from the first longitudinal fold FL1 and the second longitudinal fold FL2. The opening force is easily applied to both sides in the width direction of the absorbent article 1 at the time of opening, and the absorbent article is easily developed.

  The adhesive 50 is not disposed in the region overlapping the first longitudinal fold FL1 and the second longitudinal fold FL2 in the thickness direction T, but on the inner side in the width direction and the outer side in the width direction with respect to the first longitudinal fold FL1 and the second longitudinal fold FL2. Has been placed. For example, the adhesive 50 for bonding the packaging sheet 70 and the absorbent article 1 is provided on the outer side in the width direction of the first longitudinal fold FL1 and the second longitudinal fold FL2, so that the first longitudinal fold FL1 and the second longitudinal fold FL1 When a force is applied to the packaging sheet 70 in an attempt to develop the longitudinal crease FL2 as a base point, a force is applied to the absorbent article in a direction in which both side portions in the width direction of the absorbent article 1 develop, and the absorbent article 1 becomes easier to deploy.

  The wing parts 43 and 44 are thinner than the absorber 30 and relatively easily wrinkled. In addition, an adhesive is attached to the back surfaces of the wing parts 43 and 44, and the adhesives adhere to each other when the wing parts 43 and 44 are folded back to the non-contact surface side of the underwear. Wrinkles may occur. However, since the absorbent article can be easily developed, the wing portions 43 and 44 can be appropriately folded back to the back side, and a problem that wrinkles occur in the wing portions 43 and 44 can be prevented.

(Second Embodiment)
Next, the absorbent article packaging body 101 according to the second embodiment will be described in detail with reference to FIGS. 7 and 8. In the following description of the embodiment, a configuration different from that of the first embodiment will be described, and description of the same configuration will be omitted. FIG. 7 is a plan view seen from the skin contact surface of the package 101 of the absorbent article according to the second embodiment, and FIG. 8 is a schematic cross-sectional view of the BB cross section of FIG.

1A of absorbent articles which concern on 2nd Embodiment differ from the absorbent article 1 which concerns on 1st Embodiment, and the absorber 30 is arrange | positioned on the width direction outer side of 1st longitudinal fold FL1 and 2nd longitudinal fold FL2. Yes. The first longitudinal crease FL1 and the second longitudinal crease FL2 overlap the lower layer absorber 31 in the thickness direction T. The lower layer absorbent body 31 is provided with a low-rigidity area LA having a lower rigidity than the rigidity of the central portion located at the center in the longitudinal direction L and the width direction W of the absorbent body 30. In FIG. 7, the low-rigidity area LA is indicated by oblique lines. The central portion is a portion located in the center in the longitudinal direction of the absorber 30 and in the center in the width direction, and is a portion where the upper-layer absorber 32 is disposed in the present embodiment. Moreover, the center part may be comprised so that the area | region which contact | abuts an excretion port may be included. The central portion is configured to have a higher basis weight than portions other than the central portion. The basis weight of the central portion is, for example, 400 to 800 g / m ² .

  The low-rigidity area LA is configured to be thinner than the thickness of the absorber 30 where the upper-layer absorber 32 is disposed and lower than the basis weight of the absorber 30 where the upper-layer absorber 32 is disposed. The rigidity of the low-rigidity area LA is lower than the part where the upper-layer absorber 32 is disposed. The low rigidity region LA is disposed so as to overlap at least the first longitudinal fold FL1 and the second longitudinal fold FL2 in the thickness direction. More preferably, the low-rigidity area LA is disposed so as to straddle the first longitudinal fold FL1 and the second longitudinal fold FL2 in the width direction W. The length in the width direction of the low-rigidity area LA is, for example, 2 to 10 mm, and a more preferable length is less than 5 mm. In addition, it is not preferable that the length in the width direction of the low-rigidity region is 10 mm or more because the absorbent article in the low-rigidity region LA may be distorted.

  As a method for forming the low-rigidity region, for example, when manufacturing an absorbent body by laminating pulverized pulp, a protrusion is provided in a portion corresponding to the low-rigidity region of the plate on which the pulp is deposited, The thickness can be reduced. As the plate, a mesh plate can be used. By adjusting the thickness of the protrusion, the basis weight and thickness of the low-rigidity region can be adjusted. In addition, for example, a low rigidity region can be formed by stacking a plurality of sheets to form an absorbent body and reducing the number of layers of the sheets that are stacked only in the low rigidity region.

  According to the package of the absorbent article configured as described above, the first longitudinal fold FL1 and the second longitudinal fold FL2 are formed in the low-rigidity region, so that the absorption by the first longitudinal fold FL1 and the second longitudinal fold FL2 is performed. The body folds can be made difficult to remain.

(Third embodiment)
Next, the absorbent article packaging body 102 according to the third embodiment will be described in detail with reference to FIG. 9. FIG. 9: is the top view seen from the skin contact surface of the package 102 of the absorbent article which concerns on 3rd Embodiment. In the absorbent article 1B according to the third embodiment, the absorbent body 30 is provided on the outer side in the width direction of the first longitudinal fold FL1 and the second longitudinal fold FL2 similarly to the absorbent article 1A according to the second embodiment. However, the configuration of the absorbent article 1A according to the second embodiment and the low rigidity region is different.

  The absorber 30 is provided with a low rigidity region whose rigidity is lower than that of the upper layer absorber 32. The low rigidity region is a region where the slit 33 provided in the absorber 30 is formed. The slits 33 are provided intermittently along the first longitudinal fold FL1 and the second longitudinal fold FL2. If the length of the slit 33 in the longitudinal direction is increased, the folds of the absorber 30 are difficult to remain. However, if the length of the slit 33 in the longitudinal direction is too long, the rigidity of the absorber 30 in the longitudinal direction may be lowered. Therefore, it is desirable that the length between the slits in the longitudinal direction is, for example, 5 mm or more.

  As a method for forming the low-rigidity region, for example, a slit is formed by sandwiching an absorber between a pair of rolls including a roll having a blade (upper shaft) and a roll with a groove (lower shaft). Can do. In addition, for example, when manufacturing an absorbent body by laminating pulverized pulp with a mesh-like plate, a slit is formed by providing a protrusion or the like in a portion corresponding to the slit so that the pulp does not accumulate on the protrusion. can do.

  Next, the absorbent article packaging body according to the modification will be described in detail with reference to FIGS. 10 and 11. FIG.10 and FIG.11 is a schematic cross section of the AA line shown in FIG. 1 of the package of the absorbent article which concerns on a modification. As shown in FIG. 10, the absorbent article packaging body 103 according to Modification 1 has the absorbent body 30 in the thickness direction T on the outer side in the width direction with respect to the first longitudinal fold FL1 and the second longitudinal fold FL2 of the absorbent body 30. A compressed squeezed portion 22 is formed. Moreover, the compression part 23 which compressed the absorber 30 and the surface sheet 10 to the thickness direction T is formed in the width direction inner side with respect to 1st longitudinal fold FL1 and 2nd longitudinal crease FL2 of the absorber 30. As shown in FIG. The portion where the pressing portion is formed has high rigidity. A difference in rigidity is generated between the first longitudinal fold FL1 and the second longitudinal fold FL2 and the width direction inner side and the width direction outer side.

  By increasing the rigidity of the absorbent body on the outer side in the width direction than the first longitudinal fold line FL1 and the second longitudinal fold line FL2, a force to open the absorbent article 1 on both sides in the width direction is applied when the absorbent article package is opened. It becomes easy to develop the absorbent article. In addition, by increasing the rigidity of the absorbent body on the inner side in the width direction than the first longitudinal fold line FL1 and the second longitudinal fold line FL2, the first longitudinal fold line FL1 and the second longitudinal fold line FL2 that are most exerted when the absorbent article package is opened. The rigidity with respect to the longitudinal crease FL2 can be increased, and the durability against the force during deployment can be increased.

  In the absorbent article packaging body 104 according to the modified example 2, the elastic members 60 are provided on the side sheets 41, 42 provided on the outer side in the width direction than the first longitudinal fold FL1 and the second longitudinal fold FL2. Three elastic members 60 are provided along the longitudinal direction L of the absorbent article 1. The elastic member 60 is a rubber thread of 470 dtex, and is disposed between the side sheets 41 and 42 that are folded back in a state of being stretched about 1.3 times in the longitudinal direction. When the elastic member 60 contracts, the side sheets 41 and 42 contract, and a leak-proof wall is formed on the outer side in the width direction of the absorber 30. When the leak-proof wall is provided in this manner, the side sheets 41 and 42 are overlapped and contracted by the elastic member, and therefore, the rigidity of the absorber 30 positioned on the outer side in the width direction than the first longitudinal fold FL1 and the second longitudinal fold FL2. The package of the absorbent article can be easily developed due to the difference in rigidity.
