  With reference to FIGS. 1-7, the absorbent article 1 which concerns on embodiment, and the package 100 of the absorbent article which packaged this absorbent article 1 with the packaging sheet 70 are demonstrated. FIG. 1 is a plan view seen from the skin contact surface side of the absorbent article package, and FIG. 2 is a rear view of the absorbent article package. 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 packaging mode of the absorbent article 1 will be described in detail later.

  The absorbent article 1 includes a liquid permeable top sheet 10 that transmits liquid, a liquid impermeable back sheet 20 that does not transmit liquid, and an absorbent main body 1A having an absorbent body 30 and a width wider than the absorbent main body 1A. And a flap portion 1B extending outward in the direction. The absorbent main body 1 </ b> A is a portion where the topsheet 10, the backsheet 20, and the absorber 30 are laminated, and the flap portion 1 </ b> B is a portion on the outer side in the width direction than the absorber 30.

  The absorber 30 is disposed between the top sheet 10 (or the sheet material 80 containing Chinese medicine material) 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.

  The flap portion 1B includes a wing flap portion 43 disposed on the outer side in the width direction of the excretion opening contact region that contacts the excretion opening of the wearer, and a hip flap portion 44 disposed rearward of the wing flap portion 43. Prepare. Further, the absorbent article 1 includes a side sheet 41 provided outside the absorbent body 30 in the width direction W.

  The excretory opening contact region is a region that contacts the vaginal opening of the wearer in the absorbent article 1, and, for example, when the absorbent article 1 is worn on the wearer's underwear, It is an area | region arrange | positioned between opening. The center of the excretion opening contact area is the center in the longitudinal direction and the width direction of the area where the wearer's excretion opening contacts. For example, in an absorbent article having a wing flap, the longitudinal center of the wing flap is the longitudinal center of the excretory opening contact region. Moreover, in the absorbent article which does not have a wing flap part, the position where the length dimension of the width direction of an absorber is the shortest becomes the center of the longitudinal direction of an excretion opening | mouth contact | abutting area | region.

  The top sheet 10 is a liquid-permeable sheet that transmits liquid such as body fluid. The top sheet 10 covers at least the surfaces of the absorber 30 and the sheet material 80. 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.

  In order to suppress the propagation of liquid on the top sheet 10, the surface of the top sheet 10 on the skin contact side may be subjected to uneven processing, or by applying air when forming the top sheet 10 made of a non-woven fabric, You may form the unevenness of a fabric weight. Moreover, you may provide between the surface sheet 10 and the absorber 30 the second sheet for drawing in a bodily fluid from the surface sheet 10 side to the absorber 30 side.

  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 absorbent body 30 includes an absorbent sheet 31 made of a tissue or a non-woven fabric, and an absorbent core 32 disposed on the skin contact side of the absorbent sheet 31 and laminated with pulp fibers. The absorbent core 32 includes a lower absorbent core 32A that is in contact with the skin contact side surface of the absorbent sheet 31, and an upper absorbent core 32B that is in contact with the skin contact side surface of the lower absorbent core 32A. Have.

  An absorption sheet can be formed with a tissue or a nonwoven fabric. As a nonwoven fabric which comprises an absorption sheet, it is a nonwoven fabric which consists of thermoplastic fibers, Comprising: The nonwoven fabric which performed the hydrophilic process and the nonwoven fabric which consists of hydrophilic fibers can be used. In addition, an airlaid sheet obtained by forming hydrophilic fibers or powder into a sheet by an airlaid method can be used as the nonwoven fabric constituting the absorbent sheet.

  The absorbent core 32 is configured by laminating pulp fibers. The pulp fibers of the absorbent core 32 are not covered with a tissue or a nonwoven fabric and are in contact with the topsheet 10. The absorption core 32 functions as a laminated body in the present invention.

  The absorbent core 32 is smaller than the absorbent sheet 31 in the longitudinal direction L and the width direction W. The upper absorbent core 32B is smaller in the longitudinal direction L and the width direction W than the lower absorbent core 32A. The upper absorbent core 32B is configured such that the weight of the absorbent material is higher than that of the lower absorbent core 32A, and is disposed in the central area CA including the excretory opening contact area.

  The upper absorbent core 32B is provided in a region surrounded by the compressed portion in which the topsheet 10 and the absorbent body 30 are compressed in the thickness direction in the plan view shown in FIG. Central area | region CA is an area | region enclosed by the 1st pressing part mentioned later in planar view.

  The density of the absorbent sheet 31 is higher than the density of the absorbent core 32, and both the absorbent sheet 31 and the absorbent core 32 are arranged along the longitudinal direction and extend outward in the width direction from the first pressing portion described later. The bodily fluid guided to the outer side in the width direction than the first pressing portion diffuses into the absorbent sheet having a relatively high density, and the bodily fluid is also transported to the lower region of the absorbent core 32. Since the absorption efficiency is improved by diffusing body fluid, it is difficult to exceed the absorption capacity in the central region including the excretory opening contact region.

  In the present embodiment, the upper absorbent core 32B and the lower absorbent core 32A are integrated. The upper absorbent core 32B and the lower absorbent core 32A may be configured separately or may be integrated. The absorbent core 32 according to the present embodiment is formed by integrating an upper absorbent core 32B and a lower absorbent core 32A. When the absorbent sheet 31 and the absorbent core 32 are configured separately, they may be bonded together with an adhesive such as a hot melt adhesive.

  Between the absorber 30 and the surface sheet 10, the sheet material 80 containing a Chinese medicine material is provided. The sheet material 80 is disposed at least in the excretion opening contact region. The excretory opening contact region is a region that is in close contact with the wearer. By providing the sheet material 80 in the central region including the excretory opening contact region, it becomes easy to impart Chinese medicine components to the wearer. Further, the excretory opening contact region is a region where the body fluid is most discharged. By providing the sheet material 80 in the central region, the odor of the body fluid can be reduced by the scent component, and the wearing feeling can be improved.

  The sheet material 80 is in contact with the pulp fibers of the absorbent core. The sheet material 80 has a rectangular sheet shape in plan view, and has four corners 80A, 80B, 80C, and 80D that are an outer end in the longitudinal direction and an outer end in the width direction. The corners of the sheet material have front corners 80A and 80B located on the front side and rear corners 80C and 80D located on the rear side. The configuration of the sheet material 80 will be described in detail later.

  In a plan view, a compressed portion is formed around at least a part of the sheet material 80. The pressing part is formed by compressing the absorber 30 and the topsheet 10 at least in the thickness direction. The pressing part includes a first pressing part 23 arranged along the longitudinal direction on the outer side in the width direction than the sheet material 80, and a second pressing part 24 arranged on the outer side in the longitudinal direction from the sheet material 80. The 2nd pressing part 24 is arrange | positioned rather than the corner | angular part 80A, 80B, 80C, and 80D of the sheet | seat material 80 in the width direction.

  Specifically, the second squeezed portion 24 is disposed on the outer side in the longitudinal direction and on the inner side in the width direction than the front corner portions 80A and 80B of the sheet material 80, and on the inner side in the longitudinal direction and in the width direction than the front corner portions 80A and 80B. The 1st pressing part 23 is arrange | positioned on the outer side. The 1st pressing part 23 and the 2nd pressing part 24 are isolate | separated and arrange | positioned.

  For example, when the 1st pressing part 23 and the 2nd pressing part 24 are continuously arrange | positioned cyclically | annularly and the sheet | seat material 80 is arrange | positioned inside, the corner | angular part of the sheet | seat material 80 will interfere with an annular | circular shaped pressing part, and a sheet | seat material In some cases, the area of the substrate could not be increased sufficiently.

  However, since the 1st pressing part 23 and the 2nd pressing part 24 are arrange | positioned separately, and the corner | angular part of the sheet | seat material is arrange | positioned in the clearance gap, the 1st pressing part 23 and the 2nd pressing part 24 continue. Compared with the arrangement | positioning arrange | positioned, a corner | angular part can be arrange | positioned between the 1st pressing part 23 and the 2nd pressing part 24, and the sheet | seat material of a wider area can be arrange | positioned.

  Furthermore, since the 1st pressing part 23 and the 2nd pressing part 24 are parted and are not connected, it can suppress that a bodily fluid spread | diffuses excessively along a pressing part. For example, if the body fluid that diffuses along the first compressed portion diffuses along the second compressed portion, the body fluid may excessively diffuse in the longitudinal direction. However, the longitudinal direction outer side edge part of a 1st pressing part is parted with the 2nd pressing part, and can suppress the spreading | diffusion of the bodily fluid from a 1st pressing part to a 2nd pressing part.

  The absorbent article 1 configured as described above is deformed inward in the width direction with the first pressing portion as a base point when pressed from the outer side in the width direction while being worn by the wearer. FIG. 4 is a diagram schematically showing a deformation mode of the absorbent article 1 in the mounted state. FIG. 4 is based on the cross section shown in FIG. FIG. 4A shows a state before the deformation, and FIG. 4B shows a state after the deformation.

  In the state before a deformation | transformation, as shown to Fig.4 (a), the sheet | seat material 80 of the absorbent article 1 is a substantially smooth state, and is arrange | positioned facing a wearer's excretion opening | mouth. In a state where a force from the outer side in the width direction toward the inner side in the width direction is applied to the central region where the upper absorbent core 32B is disposed from this state, as shown in FIG. 4 (b), the pair of first pressing parts 23 Deforms inward in the width direction.

  When the absorbent article 1 is pressed from the outer side in the width direction to the inner side in the width direction, the absorbent core on the inner side in the width direction is pressed through the pressing part. At this time, the surface of the absorbent core on the sheet material side is not provided with a tissue or the like, and the pulp fibers are in contact therewith. In addition, the pulp fiber is relatively soft and softly deformed.

  Therefore, when the absorbent article 1 is pressed inward in the width direction, the pulp fibers are easily deformed into a convex shape, and the deformation of the pulp fibers is not suppressed by the tissue or the like, and thus propagates directly to the sheet material 80. To do. Compared to the state before the deformation, the upper absorbent core 32B approaches the wearer side. Therefore, the top sheet 10 and the sheet material 80 are arranged closer to the wearer.

  Moreover, the 2nd pressing part is extended in the width direction. When a force is applied from the outer side in the width direction toward the inner side in the width direction, the second pressing part suppresses deformation toward the inner side in the width direction, and the absorbent core between the first pressing parts is excessively deformed into a convex shape. Can be suppressed.

  Furthermore, a pressing part is the 3rd pressing part 25 arrange | positioned ahead rather than the 2nd pressing part 24 located in the front side, and the 4th pressing part arrange | positioned rather than the 2nd pressing part 24 located in the back side. And a point-like squeezing part 27 arranged on the outer side in the width direction than the first squeezing part 23 and on the outer side in the longitudinal direction than the second squeezing part 24.

  A plurality of the point-like compressed parts 27 are formed at intervals. The point-like compressed part 27 is arranged on the outer side in the width direction than the first compressed part 23, and is not arranged on the inner side in the width direction than the first compressed part 23. Therefore, when a force is applied from the outer side in the width direction toward the inner side in the width direction by the wearer's leg or the like, a region (a dotted pressing part is formed in the width direction outer side than the first pressing part). (Region), while maintaining a smooth state, the region on the inner side in the width direction than the first pressing portion (region where the upper absorbent core 32B is disposed) can easily approach the wearer side.

  Moreover, the area | region of the width direction outer side from the 1st pressing part 23 becomes rigid by the point-shaped pressing part 27 being formed, and becomes easy to transmit the stress from the width direction outer side to the 1st pressing part 23. . Therefore, the sheet material 80 arranged on the inner side in the width direction than the first pressing portion 23 is more likely to be in close contact with the wearer, and the components of the Chinese medicine material can be imparted to the wearer.

  Moreover, the center of the longitudinal direction of the 1st pressing part 23 is the convex shape which protrudes toward the width direction outer side, Comprising: The length of the width direction of the 1st pressing part 23 is comprised longest. Therefore, when a force is applied to the absorbent article from the outer side in the width direction to the inner side in the width direction, it becomes easy to secure the height of the deformed portion, and the sheet material 80 is easily adhered to the body. . Moreover, the body fluid which diffuses along the 1st pressing part moves toward the width direction inner side gradually toward a longitudinal direction outer side. Therefore, side leakage can be suppressed.

  In addition, the pressing part of an absorbent article should just be formed by pressing at least the surface sheet 10 and the absorber 30 in the thickness direction T, and can employ | adopt various structures. For example, it can be formed by pressing or embossing, and the shape thereof may be a lattice network or a honeycomb shape. Moreover, although the 1st pressing part 23 and the 2nd pressing part 24 of this Embodiment are each comprised by the several pressing part arrange | positioned discontinuously, even if formed continuously in linear form Good.

  In addition, the sheet material 80 in the present embodiment is configured to be separable from the absorber 30. For example, when the absorbent article is used for a long time, the absorbent body 30 may be swung by moisture or the like, and the absorbent body 30 may not be deformed in a convex shape toward the wearer. However, since the sheet material 80 is separable from the absorber 30, even if the absorber 30 is not deformed into a convex shape due to the deformation, the top sheet 10 and the sheet material 80 are dissociated from the absorber 30, and the surface The sheet 10 and the sheet material 80 can be deformed to the body side.

  The top sheet 10, the sheet material 80, the absorber 30, and the back sheet 20 may be joined to prevent the respective interlayer separation. These joints can be used alone or in combination with embossing, ultrasonic waves, hot melt adhesives, and the like. Further, the absorber may be embossed in order to prevent the absorber from being deformed or twisted when worn, or to adjust the thickness of the absorber.

  The side sheets 41 are disposed on both sides of the top sheet 10. The side sheet 41 can be selected from the same material as the top sheet 10. However, in order to prevent menstrual blood from flowing over the side sheet 41 to the outside of the absorbent article 1, it is preferable to have hydrophobicity or water repellency. Specific examples include spunbond nonwoven fabrics and SMS nonwoven fabrics. In particular, an air-through nonwoven fabric is preferable in order to reduce irritation to the skin due to rubbing.

  The side sheet 41 covers a part of the side edge of the absorber 30 and the flap portion 1B. The inner end portion 41E in the width direction of the side seat 41 is disposed adjacent to the first longitudinal fold FL1 and the second longitudinal fold FL2 outside the first longitudinal fold FL1 and the second longitudinal fold FL2, which will be described later, on the outer side in the width direction. ing.

  In the absorbent article 1, the periphery of the surface sheet 10, the side sheet 41, 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.

  A plurality of adhesive regions coated with an adhesive are provided on the surface of the back sheet 20 that contacts the undergarment. The adhesive region includes a main body adhesive region 51 (see FIG. 3) provided on the non-skin contact side surface of the absorbent main body 1A and a flap adhesive region 52 provided on the non-skin contact side surface of the flap portion 1B. (See FIG. 3). In addition, although the flap adhesion area | region 52 which concerns on this Embodiment is provided only in the wing flap part 43, you may be provided in the hip flap part 44. FIG.

  In a state before use, the main body adhesive region 51 is covered with a main body sheet 61 as a release sheet, and the flap adhesive region 52 is covered with a flap sheet 62 as a release sheet. The main body sheet 61 and the flap sheet 62 prevent the adhesive from deteriorating before use.

  The main body sheet 61 is disposed between the main body adhesive region 51 and the packaging sheet 70. The surface of the main body sheet 61 on the main body adhesive region 51 side is subjected to a mold release process and is configured to be separated from the main body adhesive region 51. The surface of the flap sheet 62 on the side of the flap adhesive region 52 is subjected to a mold release process, and is configured to be separated from the flap adhesive region 52.

  The main body sheet 61 and the flap sheet 62 are each bonded to the packaging sheet 70 via an adhesive. The main body sheet and the flap sheet side surface of the packaging sheet 70 have a main body bonding area 65 to which an adhesive for bonding the main body sheet 61 is applied, and a flap bonding area 66 to which an adhesive for bonding the flap sheet 62 is applied. Are provided in plural.

  The main body adhesion region 65 has a streak shape extending in the longitudinal direction, has a width shorter than the main body adhesion region 51, and is arranged side by side more than the main body adhesion region 51. In addition, the flap adhesion region 66 has a shorter width than the flap adhesion region 52 and is arranged side by side more than the flap adhesion region 52.

  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 plastic films such as polyethylene, polypropylene, and polyester, various films such as nylon films, films laminated with nonwoven fabrics, and the like.

  Since the main body sheet 61 and the flap sheet 62 are bonded to the packaging sheet 70, when the absorbent article 1 is separated from the packaging sheet 70, the main body sheet 61 and the flap sheet 62 are separated from the packaging sheet 70 and the absorbent article 1. The adhesive region 52 is exposed.

  In addition, a hot-melt-type adhesive agent can be used for an adhesive and an adhesive agent, for example. In addition, the main body sheet and the flap sheet can be made of paper, film, or nonwoven fabric that has been subjected to a treatment release treatment that allows the main sheet and the flap sheet to be peeled without reducing the adhesive strength of the adhesive. For example, a sheet obtained by coating a polyethylene terephthalate or polypropylene film with a silicone resin or a sheet obtained by laminating a polyethylene film coated with a silicone resin on paper can be used as the main body sheet 61 and the flap sheet 62.

  The absorbent article 1 and the packaging sheet 70 configured in this manner 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 facing inward. 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.

  Then, based on FIG. 5, the sheet | seat material 80 containing a Chinese medicine material is demonstrated in detail. 5A and 5B are views showing the sheet material 80, where FIG. 5A is a plan view, and FIG. 5B is a cross-sectional view taken along the line BB in FIG. (C) is a figure which shows the modification of the bodily fluid diffusion part mentioned later. At least a part of the sheet material 80 is surrounded by the compressed portion in plan view.

  The sheet material 80 is composed of a mixed material 81 obtained by mixing at least pulp-containing absorbent material and Chinese medicine material, and an exterior sheet 82 disposed on the surface sheet side surface of the sheet material and the surface side of the sheet material laminate. Has been.

Specifically, the herbal medicine material of the sheet material 80 may be at least one of herbal medicines, Toba, Toki, and Katsuki. Chinese medicine material according to the present embodiment, mugwort the basis weight 7 g / m ^2, angelica of basis weight 7 g / m ^2, is constituted by Koubushi having a basis weight of 7 g / m ^2.

The effects of cocoon leaves are warming the body, increasing appetite, promoting bile secretion and hemostasis, and can include abdominal pain, heartburn, diarrhea, constipation, nosebleeds, hematuria, and hemorrhoids.
As the effect of Toki, gynecological diseases can be mentioned as blood replacement, tonic and analgesic for poor blood color, coldness, and blood circulation disorder.
Examples of the efficacy of Kobushi include menstruation, blood purification, analgesia, gynecological diseases such as menstrual irregularities, menstrual pain, menopause as sedatives, chronic gastritis, duodenal ulcer, and neurogenic gastritis.

  It is desirable that the sheet material 80 is disposed in the excretion opening contact area that contacts the excretion opening of the wearer. The length of the sheet material 80 in the width direction is, for example, 20 to 60 mm, and preferably 20 to 40 mm. The length in the longitudinal direction of the sheet material is 20 to 120 mm, preferably 50 to 80 mm.

Moreover, the absorption pulp mixed with a Chinese medicine material can use the same thing as the absorption pulp used for the absorption sheet 31. FIG. The density of the sheet material 80 is desirably higher than the density of the absorbent core 32. Specifically, the density of the absorbent core of the present embodiment is 0.5 to 0.10 g / cm ³ , and the density of the sheet material is 0.10 to 0.30 g / cm ³ .

  When the density of the sheet material 80 is higher than the density of the absorbent core 32, the body fluid in the sheet material can be drawn more easily, and menstrual blood staying on the skin can be drawn in instantaneously. Further, since the density of the sheet material is relatively high, the rigidity is not easily lowered even when exposed to a high humidity environment such as when the absorbent article is used for a long time, and the sheet material 80 can be prevented from being swayed. .

  Since the density of the sheet material 80 is relatively high, the diffusibility of body fluid is increased, and even a small amount of menstrual blood can be contacted with many Chinese herbal medicine materials. Generally, the Chinese medicine component of the sheet material is easily diffused effectively by touching the liquid. Therefore, by increasing the diffusibility of the sheet material 80, it becomes possible to exhibit the effects of more Chinese herbal medicine components even with a small amount of menstrual blood.

  Moreover, the sheet | seat material 80 is not arrange | positioned and the pressing part is not formed in the area | region between the sheet | seat material and 1st pressing part in the width direction. Therefore, the area between the sheet material and the first pressing part in the width direction has a lower density than the area where the sheet material is arranged, and the density is lower than the area where the first pressing part is formed. Become.

  Generally, when a large amount of menstrual blood is discharged at a time, menstrual blood moves on the top sheet without passing through a high-density sheet material. At this time, by providing the low density region between the sheet material and the first pressing portion, menstrual blood that has moved on the top sheet can be drawn to the absorber side by the low density region. Therefore, side leakage can be suppressed.

  The sheet material 80 is formed with a body fluid diffusion portion 83 for diffusing body fluid in the longitudinal direction of the absorbent article.
