The present invention relates to an absorbent article such as a sanitary napkin or the like, and more particularly to an absorbent article which is capable of suppressing distortion, wrinkles, and the like of the flap portion extending outward in the width direction of the absorbent body at the rear portion of the absorbent article.

Patent Document 1 discloses a sanitary napkin as an absorbent article, which has a fin that extends outward in the width direction from the rear portion of the absorbent article, and is embossed by the embossing process. The uneven portion is formed. The rear flap of the sanitary napkin of Patent Document 1 is increased in rigidity by embossing. By increasing the rigidity of the rear flap, it is possible to prevent the occurrence of distortion, wrinkles, and the like of the rear flap when worn.

[Patent Document 1] Japanese Laid-Open Patent Publication No. 2003-339765 (Fig. 1, paragraph 0016, etc.)

However, the above-mentioned physiological sanitary napkin has the following problems.

In the sanitary napkin described in Patent Document 1, since the rigidity of the rear flap is relatively high, there is a possibility that the rear flap cannot be appropriately arranged along the body curve. Therefore, the sanitary napkin cannot be fitted to the body, causing leakage of body fluid, and there is a fear that the sense of wear is deteriorated. Moreover, since the rear fin portion is hard, there is a case where wrinkles, creases, and the like are formed, for example. Wrinkles, creases, and the like come into contact with the wearer, causing a deterioration in the sense of wear.

The present invention has been made in view of the above problems, and an object of the invention is to provide an absorbent article which can suppress wrinkles, twists, and the like of a flap portion during wear, and can prevent wear along the body arrangement of a wearer. Feeling worse.

In order to solve the above problems, the absorbent article of the present invention has an absorbent article having a front-rear direction (longitudinal direction L) and a width direction (width direction W) orthogonal to the front-rear direction, and is characterized in that it has absorption a body portion (body portion 2) of the body (absorbent body 30); a wing portion (wing portion 43) that protrudes outward in the width direction from the body portion and that is folded toward the non-skin contact surface side of the wearer's underwear; a fin portion (wing portion 60) that protrudes outward in the width direction from the main body portion at a position rearward of the wing portion, and the fin portion is formed such that a length of the fin portion in the width direction is formed as a constricted neck (first constricted portion 61) having a shorter length in the width direction than the region before and after the first region; a first wing that protrudes outward in the width direction from the constricted portion at a position on the front side of the constricted portion a second flap portion (second flap portion 64) that protrudes outward in the width direction from the constricted portion at a position closer to the rear side than the constricted portion, and a second flap portion (the second flap portion 64) The fin portion is formed to be recessed in the thickness direction of the fin portion Depression portion (recessed portion 70), the recessed portion toward the rear of the train, from the inside to the outside in the width direction extending in the width direction.

The wing portion is a portion to which the force is applied from the outer side toward the inner side in the width direction when the wearer closes the foot. The fin portion is disposed further rearward than the wing portion, and when the force is applied from the outer side in the width direction toward the inner side in the width direction, the force is applied from the front side where the wing portion is located toward the rear side. At this time, the fin portion is deformed by the constricted neck as a base point, and the force from the front can be absorbed.

Since the force applied to the flap portion from the side of the wing portion is absorbed by the constricted portion, the force transmitted toward the rear of the neck portion can be reduced. Therefore, it is possible to prevent the force from the wing portion side from propagating to the entire flap portion, and it is possible to prevent wrinkles, distortion, and the like from occurring in the entire flap portion.

Further, since the depressed portion is formed so as to extend outward from the width direction inner side in the width direction toward the rear side so that the depressed portion is along the direction in which the force is applied, the depressed portion becomes the folding starting point, and the flap portion can naturally fold. Therefore, even if the flap portion is not reluctantly fitted to the body or the underwear. Therefore, it is less likely to cause disordered wrinkles in the flap portion, and it can be deformed without discomfort, and a firm wearing feeling can be obtained.

(First embodiment)

The absorbent article 1 according to the first embodiment will be described with reference to Figs. 1 to 3 . 1 is a plan view of an absorbent article, and FIG. 2 is a rear view of the absorbent article. Figure 3 is a cross-sectional view taken along line A-A' of Figure 1. The absorbent article 1 of the present embodiment is, for example, a sanitary napkin.

The absorbent article 1 has a surface sheet that abuts against the wearer's skin. 10; a liquid impermeable inner sheet 20 that does not allow liquid to pass through; and an absorbent body 30. The absorber 30 is disposed between the surface sheet 10 and the back sheet 20. Therefore, the absorber 30 is shown by a broken line in FIGS. 1 and 2. The absorber 30 is disposed at a central portion along the longitudinal direction L and the width direction W of the absorbent article 1 in the front-rear direction.

The absorbent article 1 includes a main body portion 2 having the absorbent body 30, a wing portion 43 disposed closer to the outer side in the width direction than the main body portion 2, and a rear side of the wing portion 43 disposed closer to the width direction than the main body portion 2. The outer flap portion 60. The wing portion 43 is configured to be folded back toward the non-skin contact surface side of the wearer's underwear.

Fig. 1 shows a region RA of a wing portion in the longitudinal direction; and a region RB of a fin portion in the longitudinal direction. The flap portion of the present embodiment is a region extending outward in the width direction from the main body portion 2, and extends rearward from the rear end portion of the wing portion. The rear end portion of the wing portion of the flap portion 60 which is the front end portion is located between the wing portion 43 and the flap portion 60, and is located at the innermost portion in the width direction. The rear end portion of the flap portion 60 is a portion which is closer to the rear end portion of the absorbent article and which is more inwardly contracted than the front and rear regions. The rear end portion of the flap portion of the present embodiment is aligned with the rear end portion of the first recess portion 71 to be described later. Further, the rear end portion of the flap portion 60 may coincide with the rear end portion of the absorbent article or may not coincide with the rear end portion of the absorbent article.

Further, the absorbent article 1 further includes a side sheet 41 that is provided on the outer side of the absorber 30 in the width direction W. The main body portion 2 is a region in which the absorber 30 is disposed in a plan view, that is, a region in which the surface sheet 10, the back sheet 20, and the absorber 30 are laminated.

The surface sheet 10 is a liquid permeable sheet that can permeate a liquid such as a body fluid. The surface sheet 10 is a surface covering at least the absorber 30. The surface sheet 10 is a non-woven fabric, a woven fabric, a perforated plastic sheet, a mesh sheet, or the like, and a sheet-like material having a structure through which liquid can pass therethrough is not particularly limited. As a material such as woven fabric or non-woven fabric, natural fibers, chemical fibers, and the like can be used.

The inner sheet 20 has a length substantially the same as the length of the surface sheet 10. In the inner sheet 20, a sheet in which a permeable air-permeable resin film is bonded to a non-woven fabric such as a polyethylene sheet, polypropylene or the like, a permeable air-permeable resin film, a spun bond, or a water needle can be used. The inner sheet 20 is preferably a material having a softness which does not cause discomfort when worn. The inner sheet 20 is preferably liquid-impermeable and moisture-permeable, and the microporous sheet which can be subjected to elongation treatment by melting an olefin-based resin such as polyethylene or polypropylene and mixing the inorganic filler Composition.

The absorbent body 30 contains hydrophilic fibers and pulp. The absorbent body 30 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 powders by an air-laid method, or may be an air-laid sheet in which a hydrophilic fiber or a powder is formed into a sheet by an air-laid method. Alternatively, it may be formed by disposing a pulverized pulp mixed with a superabsorbent polymer on a thin paper (for example, a basis weight of 15 g/m ² ) and then wrapping it on a thin paper.

The absorbent body 30 of the present embodiment is composed of a protective paper (not shown) in which pulp such as cotton pulp or synthetic pulp is laminated to a basis weight of 100 to 300 g/m ² . Furthermore, the absorbent body 30 may have a substantially uniform thickness or a non-uniform thickness. The protective paper is used to hold the shape of the pulp, and for example, crepe paper, tissue paper, or the like can be used.

The absorbent body 30 has a shape extending in the front-rear direction and is slightly smaller than the inner sheet 20. The length of the absorbent body 30 in the width direction W corresponds to the femoral spacing of an adult female, which is about 50 to 80 mm. The absorber 30 is attached to the inner sheet 20 by an adhesive such as hot melt adhesive. Further, in the present embodiment, the absorber 30 and the surface sheet 10 are adhered by a hot melt adhesive.

The absorbent body 30 is provided to include at least a center of a discharge opening abutting region that abuts the wearer's excretory opening. The center of the excretory opening abutment region coincides with the center in the longitudinal direction and the width direction of the central region where the wearer's excretory opening abuts. For example, in an absorbent article having a wing portion, the center of the wing portion in the longitudinal direction is the center of the longitudinal direction of the central region. Further, in the absorbent article having no wing portion, the position at which the length dimension of the absorbent body in the width direction is the shortest is the center in the longitudinal direction of the central region. Further, the excretory opening abutment region is included in an area that abuts the wearer's inter-femoral portion and is located between the wearer's feet.

The side sheets 41 are disposed on both sides of the surface sheet 10. Similarly to the surface sheet 10, the side sheet 41 is disposed closer to the skin contact surface side than the absorber 30, and constitutes a part of the surface sheet of the present invention. The side sheets 41 are selectable from the same material as the surface sheets 10. However, in order to prevent menstrual blood from flowing over the side sheet 41 and flowing toward the outside of the absorbent article 1, it is preferable to have hydrophobicity or water repellency. The side sheet 41 covers a part of the side edge of the absorber 30, and the wing portion 43 and the flap portion 60.

The side sheet 41 of this embodiment is constituted by a hot air non-woven fabric. Hot air non-woven fabric is soft and has a good touch. When the flap portion is disposed along the body, the feeling of wear can be further enhanced by lifting the texture of the flap portion.

Further, in the wing portion 43 and the flap portion 60, an intermediate sheet 35 is provided between the side sheet 41 and the back sheet 20. The intermediate sheet 35 is composed of a hot air non-woven fabric. Since the hot air non-woven fabric blows hot air to the non-woven fabric, the blown air is passed through the blown air to restore the bulkiness, so that it is soft and has a good touch. When the flap portion is disposed along the body, the wearing feeling can be further enhanced.

By providing the intermediate sheet 35, a difference in thickness, a difference in rigidity, and the like are formed at the boundary between the region where the intermediate sheet is disposed and the region where the intermediate sheet is not disposed. For example, the flap portion 60 is easily deformed with the end portion of the intermediate sheet as a base point.

The intermediate sheet 35 is intermittently joined at least to the side sheet 41 via an adhesive. The intermediate sheet of the present embodiment is then applied to the surface sheet 10 and the back sheet 20 via a hot melt adhesive disposed in a spiral shape. By intermittently joining the intermediate sheet 35 to the surface sheet 10 or the like, the intermediate sheet 35 can be partially moved relative to the surface sheet, and a soft texture can be maintained.

In the absorbent article 1, the peripheral edges of the surface sheet 10, the side sheets 41, and the back sheet 20 are joined, and the absorber 30 is housed. As a method of joining the surface sheet 10 and the back sheet 20, one of hot embossing, ultrasonic, or hot melt adhesive may be used, or a plurality of them may be combined.

In the inner sheet 20, on the surface in contact with the undergarment, a rear portion to which an adhesive is applied in a plurality of regions is provided (see Fig. 2). The rear part has a rear side provided on the main body portion for fixing the absorbent article 1 to the central end portion 51 of the crotch portion of the undergarment, and a rear side of the wing portion 43. a wing attachment portion 52 that is inserted into the crotch portion for fixing the wing portion 43; and a wing portion that is provided on the inner side of the flap portion 60 for fixing the flap portion to the rear portion of the underwear to be fixed The sheet is followed by a portion 53.

In the state before use, the adhesive is in contact with a release sheet (not shown). The release sheet is used to prevent the occurrence of deterioration of the adhesive before use. Also, when used, the wearer peels off the release sheet.

Further, in the absorbent article which does not have the release sheet, it is also possible to prevent the adhesive from being deteriorated before use by the packaging sheet in which the absorbent article is individually packaged. When the adhesive is in contact with the packaging sheet, it is desirable to carry out the treatment of peeling off the adhesive on the surface of the packaging sheet without lowering the adhesive force of the adhesive.

In the absorbent article 1, a press portion 80 that compresses the surface sheet 10 and the absorbent body 30 in the thickness direction is formed. Further, the press portion may be formed by at least pressing the surface sheet 10 and the absorber 30 in the thickness direction T, and various structures can be employed. For example, it can be formed by press working, embossing, or the like, and its shape may be a lattice mesh or a honeycomb shape.

The fin portion 60 is formed with a plurality of constricted portions, and the length in the width direction is formed to be shorter than the length in the width direction of the front and rear regions. The neck portion has a first constricted portion 61 on the front side and a second constricted portion 62 on the rear side.

The flap portion 60 has a first flap portion 63 located further forward than the first constricted portion 61, and a second flap located further rearward than the first constricted portion 61 and further forward than the second constricted portion 62 The sheet portion 64 is located at a third flap portion 65 that is located further rearward than the second constricted portion 62.

The first flap portion 63 is located at the inner end portion in the width direction of the wing portion 43 from the rear inner end portion 43RI to the first constricted portion 61, and the rearward inner end portion 43RI faces rearward. Extending outside in the width direction. The first maximum width position (outer end portion) 63 WM of the first flap portion 63 located on the outermost side in the width direction is located closer to the outer side in the width direction than the first constricted portion 61. The first maximum width position 63 WM is located further rearward than the center of the first fin portion 63 in the front-rear direction.

The second flap portion 64 is in a region from the first constricted portion 61 to the second constricted portion 62 which is the rear end portion of the first flap portion 63, and goes rearward from the first constricted portion 61. Extending to the outside in the width direction. The second fin portion 64 is located at the second maximum width position (outer end portion) of the outermost width direction, and is located closer to the outer side in the width direction than the second constricted portion 62. The second maximum width position 64 WM is located further rearward of the center of the second fin portion 64 in the front-rear direction.

The third flap portion 65 is in a region from the second constricted portion of the second flap portion 64 which is the rear end portion to the rear end portion of the flap portion, and goes rearward from the second constricted portion 62 , extending outward in the width direction. The third maximum width position (outer end portion) 65WM of the third flap portion 65 located on the outermost side in the width direction is located closer to the outer side in the width direction than the second constricted portion 62. The third maximum width position 65 WM is located further rearward than the center of the third fin portion 65 in the front-rear direction.

Fig. 4 is a view schematically showing a state in which the absorbent article 1 is worn on the underpants. Figure 5 is a cross-sectional view taken along line B-B of Figure 4; The force from the outer side toward the inner side of the width direction due to the movement of the wearer or the like acts on the It is disposed in an area sandwiched by the wing portion 43 of the proximal portion of the inter-femoral portion.

The wing portion 43 is a portion to which the force is applied from the outer side in the width direction to the inner side when the wearer closes the foot. The flap portion 60 is disposed at a position rearward of the wing portion 43. When the external force is applied from the outer side in the width direction to the inner side, the force is applied from the front side where the wing portion 43 is located rearward.

At this time, since the first constricted portion 61 and the second constricted portion 62 are formed in the flap portion 60, the flap portion 60 is deformed by the first constricted portion 61 and the second constricted portion 62 as base points. And absorb the power from the front side. For example, the force applied from the side of the wing portion 43 is absorbed by the first constricted portion 61, and the force transmitted to the rear of the first constricted portion 61 can be reduced. Therefore, it is possible to prevent the force from the front side from propagating to the entire flap portion, and it is possible to prevent wrinkles, distortion, and the like from occurring in the entire flap portion.

Moreover, the maximum width positions of the first flap portion 63, the second flap 64, and the third flap portion 65 are respectively disposed at positions closer to the rear side than the center of each fin portion in the longitudinal direction. For example, when the maximum width position of each of the fin portions is located on the front side, only the front side portion of the fin portion is partially bent, and the entire fin portion cannot absorb the force.

However, by setting the maximum width position of each of the fin portions to the rear side of the center in the front-rear direction of each of the fin portions, it is possible to absorb the force in the entire fin portion, and it is possible to suppress the occurrence of wrinkles locally.

Further, the second maximum width position is located closer to the outer side in the width direction than the first maximum width position, and the third maximum width position is located closer to the outer side in the width direction than the second maximum width position. That is, the maximum width position of the wing portion located at the rear is located at the maximum width position of the wing portion located at the front. Closer to the outside of the width direction. Therefore, the force transmitted from the front can be absorbed by the front flap portion, and then absorbed by the rear flap portion. That is, it is possible to absorb power in stages. Moreover, since the width becomes wider toward the rear, it can be arranged along the underpants.

In the fin portion 60, a depressed portion 70 recessed in the thickness direction T is formed. As shown in FIG. 3, the depressed portion 70 is such that the side sheet 41, the intermediate sheet 35, and the back sheet 20 constituting the surface sheet are compressed in the thickness direction. The recessed portion 70 has a first recessed portion 71 extending rearward from the rear inner end portion 43RI of the wing portion 43 and a second recessed portion 72 that branches from the first recessed portion 71 and reaches the first constricted portion 61; The recessed portion 71 is branched and reaches the third recessed portion 73 of the second constricted portion 62; and the third recessed portion 71 is branched from the first recessed portion 71, and reaches the third maximum width position 65WM located on the outer side in the width direction of the third fin portion 65. The fourth depressed portion 74.

The depressed portion is compressed toward the thickness direction from the side of the surface sheet toward the side of the inner sheet. By forming the depressed portion 70 by compressing from the side of the front sheet toward the side of the inner sheet, it is possible to suppress cracking of the inner sheet composed of the film when the depressed portion is formed. In the present embodiment, the side of the side sheet 41 constituting the surface sheet is compressed toward the sheet side.

The second recessed portion 72, the third recessed portion 73, and the fourth recessed portion 40 are configured to extend outward in the width direction from the inner side in the width direction toward the rear side. By forming the depressed portion so as to extend outward in the width direction from the inner side in the width direction toward the rear side, since the depressed portion is in the direction in which the force is applied, the depressed portion becomes the starting point of the folding, and the flap portion can be naturally folded. Therefore, the flap portion 60 does not reluctantly match the body and the pair of panties. therefore, In the fin portion, it is less likely to cause disordered wrinkles, and it can be deformed without discomfort, and a firm wearing feeling is obtained.

Further, the outer end portion in the width direction of the third recessed portion 73 is configured to be positioned in the second constricted portion 62. With this configuration, the force transmitted through the third recessed portion 73 easily reaches the second constricted portion, and the second constricted portion 62 and the third recessed portion can be easily folded as a base point.

Further, as shown in FIG. 2, the recessed portion 70 is provided at a position where it does not overlap the fin rear portion 53 in the thickness direction T. Since the recessed portion 70 and the flap rear portion 53 are not overlapped, the flap portion is not folded by the end portion of the undergarment and the flap portion, so that the subsequent position of the undergarment is not affected, and The flap portion 60 is folded. Therefore, it is possible to prevent the flap attachment portion 53 from being peeled off from the undergarment, and it is easy to maintain the subsequent position in the entire absorbent article 1.
