Description

  The present invention relates to an absorbent article such as a sanitary napkin.

  Patent Document 1 discloses a sanitary napkin as an absorbent article having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body disposed between the top sheet and the back sheet. The sanitary napkin in which the pressing part which compressed the absorber and the surface sheet in the thickness direction of the absorbent article was formed is described. The compression part of patent document 1 is comprised by the large diameter recessed part which dented the surface sheet and the absorber partially in the thickness direction, and the small diameter recessed part further recessed rather than the large diameter recessed part in the large diameter recessed part. ing.

JP-A-8-71105 (FIG. 2, paragraph 0014, etc.)

  The surface sheet of the sanitary napkin described above is composed of thermoplastic fibers. When forming the pressing part, the absorbent article is compressed while partially heating from the top sheet side to the back sheet side. Since the part in which the pressing part of the top sheet is formed is stretched while being heated to the back sheet side, it may be formed into a film. In particular, since the portion of the top sheet where the small-diameter recesses are formed is stretched while being heated further from the state where the large-diameter recesses are formed to the back sheet side, the formation of a film is prominent.

  When the surface becomes a film, it becomes difficult to draw body fluid into the surface sheet. Therefore, the bodily fluid discharged from the wearer may not be sufficiently drawn by the face sheet and remains on the face sheet, and the wearer's feeling of wearing may deteriorate.

  This invention is made | formed in view of the above-mentioned subject, suppresses the fall of the draw-in property of the body fluid of a surface sheet by forming a pressing part, and can suppress the deterioration of a wearer's wearing feeling. An object is to provide an absorbent article.

  In order to solve the above-described problems, an absorbent article according to the present disclosure includes a liquid-permeable top sheet (top sheet 10), a liquid-impermeable back sheet (back sheet 20), and the top sheet and the back sheet. An absorbent article (absorbent article 1) having an absorbent body (absorbent body 30) disposed between the top sheet and the absorbent body in the thickness direction of the absorbent article. A plurality of compressed compressed parts (compressed parts 80) are formed, and the compressed parts are formed in a central area (central area CA) including the center of the excretory opening contact area disposed to face the excretion opening of the wearer. Provided and intermittently formed in a plurality of point-like central pressing parts (central pressing part 81), provided on the outer side in the width direction of the absorbent article than the central area, and the longitudinal direction of the absorbent article Longitudinal pressing part (longitudinal pressing part) 2), and the longitudinal direction pressing portion is recessed from the top sheet side toward the back sheet side, and the central pressing portion is recessed from the back sheet side toward the top sheet side. It is a summary.

  In the absorbent article according to the present disclosure, since the central pressing portion formed in the central region is recessed from the back sheet side to the top sheet side, compared to the central pressing portion compressed from the top sheet side to the back sheet side. In addition, damage due to heat in the surface sheet is reduced. Therefore, the surface sheet can be prevented from being formed into a film, and the body fluid discharged from the wearer can be drawn in by the surface sheet. It can suppress that a bodily fluid remains on a surface sheet, and can improve a wearer's feeling of wear.

  Since the center pressing part is arrange | positioned intermittently, the damage by the heat | fever at the time of formation of a pressing part in a surface sheet is not formed continuously. For example, when the central squeezed portion is continuously formed, damage due to heat continues, so that it is difficult to draw the discharged body fluid into the surface sheet, and the body fluid may travel on the surface sheet. However, since the part which has not received the damage by a heat | fever is arrange | positioned between center pressing parts, it can prevent that a bodily fluid spreads on a surface sheet.

It is the top view seen from the skin contact surface side of the absorptive article concerning a 1st embodiment. It is a schematic cross section of the AA cross section shown in FIG. It is a schematic cross section of the BB cross section shown in FIG. It is a figure for demonstrating the arrangement | sequence state of a center pressing part. (A) is the state visually recognized from the surface sheet side, (b) is the state visually recognized from the back sheet side. It is the top view seen from the skin contact surface side of the absorptive article concerning a 2nd embodiment.

The absorbent article 1 according to the present embodiment is, for example, a sanitary napkin.

  In the following description of the drawings, 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 ratios of dimensions are different from actual ones. Accordingly, specific dimensions and the like should be determined in consideration of the following description. Moreover, the part from which the relationship and ratio of a mutual dimension differ also in between drawings is contained.

  In addition, in the following schematic cross-sectional view, for convenience of explanation, the thickness dimension of the absorbent article is shown enlarged compared to the length dimension in the longitudinal direction and the width direction, but in the actual absorbent article, The dimension in the thickness direction is smaller than the length dimension in the longitudinal direction and the width direction.

  The absorbent article according to the embodiment is a daytime sanitary napkin. The absorbent article has a front region located on the front side of the wearer in the longitudinal direction and a rear region located on the rear side of the wearer, and the length of the front region in the longitudinal direction is the rear side. It is the same as the length in the longitudinal direction of the region.

  In the present embodiment, a sanitary napkin for daytime is described as an example, but the present invention can also be applied to a sanitary napkin for nighttime. The sanitary napkin for night use is configured such that the length of the rear region is longer than that of the front region.

  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.1 and FIG.2. 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 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 back sheet 20 has substantially the same length as that of the top sheet 10. As the back sheet 20, a polyethylene sheet, a laminated nonwoven fabric mainly composed of polypropylene, a breathable resin film, a spunbond, a sheet obtained by bonding a breathable resin film to a nonwoven fabric such as spunlace, or the like can be used. 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 is desirably liquid-impervious and moisture-permeable, and can be constituted by a microporous sheet obtained by stretching a melt-kneaded inorganic filler such as polyethylene or polypropylene. .

The absorber 30 includes hydrophilic fibers and pulp. The absorber 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 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 absorbent body 30 according to the present embodiment is configured by wrapping a pulp obtained by laminating cotton-like pulp, synthetic pulp, or the like at a basis weight of about 100 to 300 g / m ² with protective paper (not shown).

  The absorber 30 has a shape extending in the front-rear direction, and is approximately one size smaller than the back sheet 20. The length of the absorbent body 30 in the width direction W corresponds to the crotch interval of an adult female and is approximately 50 to 80 mm. In this Embodiment, the absorber 30 and the surface sheet 10 are adhere | attached with the hot-melt-adhesive 60 (refer FIG. 2).

  The side sheets 41 and 42 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 cover a part of the side edge of the absorber 30 and the wing parts 43 and 44.

  Between the top sheet 10 and the absorber 30, a top side intermediate sheet 71 is provided. The surface side intermediate sheet 71 is bonded to the absorber 30 and the surface sheet 10 via the hot melt adhesive 60. The surface side intermediate sheet 71 may be a liquid-absorbent sheet, and may be formed of the same material as the surface sheet 10, for example.

  A back surface side intermediate sheet 72 is provided between the back sheet 20 and the absorber 30. The back side intermediate sheet 72 is bonded to the absorber 30 and the back sheet 20 via the hot melt adhesive 60. The back side intermediate sheet 72 is made of a nonwoven fabric such as an SMS nonwoven fabric.

  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.

  The absorbent body 30 includes a central area CA including the center of the excretory opening contact area disposed to face the excretion opening of the wearer, and a first area FA disposed on the outer side in the longitudinal direction from the central area CA. Have.

  The center of the excretory opening contact area is the center in the longitudinal direction and the width direction of the area in which the wearer's excretion opening contacts, and coincides with the center of the central area. For example, in an absorbent article having a wing portion, the center in the longitudinal direction of the wing portion is the center in the longitudinal direction of the excretory opening contact region. Moreover, in the absorbent article which does not have a wing 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 excretory opening contact region is included in a region that contacts the wearer's crotch, and is located between the wearer's legs. In the present embodiment, the center in the longitudinal direction and the center in the width direction of the absorber 30 coincide with the center of the excretory opening contact region and the center of the central region.

  The absorbent article 1 is formed with a pressing portion 80 formed by pressing (embossing) at least the top sheet 10 and the absorbent body 30 in the thickness direction. The pressing unit 80 includes a dot-shaped central pressing unit 81, a longitudinal pressing unit 82 extending along the longitudinal direction L, a first width pressing unit 83 and a second width pressing unit 84 extending along the width direction W. And the point-like 1st pressing part 85. The pressing part according to the present embodiment is formed by pressing the top sheet 10, the top intermediate sheet 71, the absorber 30, and the back intermediate sheet 72.

  Since the pressing part is formed including the back side intermediate sheet 72, the state where the absorber 30 is sandwiched between the top sheet 10 and the back side intermediate sheet 72 is maintained even when the absorbent material is not included by the tissue or the like. it can. Therefore, even when the absorber 30 absorbs body fluid, the shape of the absorber 30 is easily maintained.

  The longitudinal direction compression part 82, the 1st width direction pressing part 83, and the 2nd width direction pressing part 84 are compressed and formed toward the back surface sheet 20 side from the surface sheet 10 side, and a back surface sheet is formed from the surface sheet 10 side. It is recessed toward the 20 side.

  On the other hand, the center pressing part 81 and the 1st pressing part 85 are compressed and formed toward the surface sheet 10 side from the back surface sheet 20 side, and are dented toward the surface sheet 10 side from the back surface sheet 20 side.

  In addition, as shown in FIG. 2, the absorber 30 is pressed from the back surface sheet 20 side to the top sheet 10 side by the dot-shaped pressing part 81 and is deformed so as to protrude to the top sheet side. However, for example, in the case of a thin absorbent body, the absorbent material in the portion where the point-like compressed portion is formed flows to the periphery, and the thickness of the absorbent body is further reduced, so that the front surface side intermediate sheet 71 and the back surface side intermediate sheet 72, the front surface side intermediate sheet 71 and the back surface side intermediate sheet 72 are brought into contact with each other. That is, the shape of the absorber 30, the front surface side intermediate sheet 71, and the back surface side intermediate sheet 72 in the portion where the point-like compressed portion 81 is formed is not limited to the examples shown in FIGS.

  The central pressing part 81 is a circular dot shape, and a plurality of the intermediate pressing parts 81 are formed intermittently. The center pressing part 81 is arranged in a fixed direction and forms a large number of virtual pressing lines. The virtual squeeze line is a first virtual squeeze line N1 that is inclined at a required angle with respect to the width direction W, and a second virtual squeeze that is inclined at a required angle with respect to the width direction W and intersects the first virtual squeeze line N1. The grid pattern is formed from the 1st virtual pressing line N1 and the 2nd virtual pressing line N2.

  The 1st pressing part 85 is circular dot shape, Comprising: A plurality is intermittently formed. The 1st pressing part 85 is arrange | positioned at predetermined intervals.

  In addition, the center pressing part 81 and the 1st pressing part 85 should just be provided with two or more intermittently, The shape is not restricted circularly, An ellipse, a star shape, a heart shape, a rhombus, etc. may be sufficient. , Not limited.

  The longitudinal direction compression part 82 is arrange | positioned in the width direction outer side of center area | region CA. The longitudinal direction compressed parts 82 are formed in two rows along the longitudinal direction L.

  The width direction squeezing part is arranged on the outer side in the longitudinal direction from the central area CA, and the first width direction pressing part 83 arranged between the central area and the first area FA and the outer side in the longitudinal direction from the first area FA. 2nd width direction pressing part 84 arrange | positioned in.

  The width direction outer side end portion of the second width direction pressing portion 84 is continuous with the front end portion and the rear end portion of the longitudinal direction pressing portion 82. In the state where the 2nd width direction pressing part 84 and the longitudinal direction pressing part 82 continued, the cyclic | annular pressing part is comprised. The 1st width direction pressing part 83 is arrange | positioned rather than the longitudinal direction pressing part 82 in the width direction inner side.

  In addition, the longitudinal direction pressing part 82 may be formed so as to be inclined with respect to a straight line along the longitudinal direction L. The longitudinal direction compression part 82 shall have an angle (acute angle side) formed by the straight line along the longitudinal direction L and the longitudinal direction compression part 82 to be 45 degrees or less. On the other hand, the width direction pressing parts 83 and 84 may be formed so as to be inclined with respect to a straight line along the width direction W. The width direction pressing parts 83 and 84 shall have an angle (acute angle side) formed by the straight line along the width direction W and the width direction pressing part of less than 45 degrees.

  The center area CA is an area surrounded by the longitudinal direction pressing part 82 and the first width direction pressing part 83. The first region FA is a region inside the annular second width direction compressed portion 84 and the longitudinal direction compressed portion 82 and outside the first width direction compressed portion 83 in the longitudinal direction.

  The central pressing part 81 is arranged in a first virtual pressing line N1 and a second virtual pressing line N2 that are inclined with respect to the longitudinal direction L and the width direction W. When the absorbent article 1 is pressed inward from the outer side in the width direction, the absorbent article 1 is easily bent along the first virtual pressing line N1 and the second virtual pressing line N2.

  Since the wearer moves one leg at a time during walking or the like, the absorbent article 1 disposed between both legs is subjected to a force in a direction twisted obliquely. Since the 1st virtual pressing line N1 and the 2nd virtual pressing line N2 incline with respect to a longitudinal direction and the width direction, the absorbent article 1 follows a wearer's movement and follows the force of the diagonal direction. It becomes easy to deform. That is, the absorbent article 1 is easily bent along the outer shape of the wearer's body, and the fit of the absorbent article 1 can be improved.

  Since the 1st virtual pressing line N1 and the 2nd virtual pressing line N2 incline with respect to the longitudinal direction L, it can suppress that the absorbent article 1 bends along the longitudinal direction L. FIG. Furthermore, since the 1st virtual pressing line N1 and the 2nd virtual pressing line N2 incline with respect to the width direction W, they can oppose the external force from the width direction outer side.

  Moreover, since the center pressing part 81 is arrange | positioned intermittently, it is hard to become harder than the width direction pressing part extended in the width direction, and the longitudinal direction pressing part extended to a longitudinal direction, and the rigidity of a one part area | region is biased. Hard to harden. Therefore, the texture of the central area including the excretion opening contact area that comes into contact with the wearer's excretion opening can be improved, and the wearing feeling can be improved.

  The cross-sectional shape of the center pressing part 81 and the 1st pressing part is convex shape which goes to a surface sheet side from a back surface sheet side, as shown in FIG. For example, the length in the width direction of the central pressing portion 81 changes in the thickness direction, and the width direction length W1 on the back sheet 20 side is longer than the width direction length W2 on the top sheet 10 side.

  Moreover, FIG. 4 is a figure for demonstrating the arrangement | sequence state of a center pressing part. FIG. 4A is an enlarged view of the region R shown in FIG. 1 as seen from the top sheet side, and FIG. 4B shows the central pressing portion 81 of the region R seen from the back sheet side. Yes. In the state visually recognized from the topsheet 10 side, the interval W3 between the central compressed portions 81 is wider than the interval W4 in the state visually recognized from the backsheet 10 side, and the central compressed portion 81 is visually recognized in a dot shape. On the other hand, in the state visually recognized from the back sheet 20 side, the interval W4 between the central compressed parts 81 is narrower than the interval W3 in the state visually recognized from the top sheet 10 side, and the central compressed part 81 is visually recognized in a line shape. The center squeezing part 81 is close to the adjacent squeezing part on the back sheet 20 side, and the center squeezing parts 81 are also deformed so as to follow the center squeezing part 81 and dent to the top sheet side. Therefore, the center pressing part 81 is dented on the surface sheet side in a line shape on the back sheet 20 side, and the absorbent article 1 is deformed so as to be convex on the wearer side.

  When an external force in a direction from the outer side in the width direction toward the inner side in the width direction is applied to the central area CA, the central pressing portion 81 is deformed so as to be crushed in the width direction. At this time, since the cross-sectional shape of the central pressing portion 81 on the back sheet side is larger than the cross-sectional shape of the central pressing portion 81 on the top sheet side, the central pressing portion 81 is deformed so as to swell toward the top sheet side. Therefore, the part in which the central pressing part 81 is formed is pushed up on the wearer side (upward), the topsheet 10 can be brought close to the excretion opening, and the body fluid excreted from the excretion opening can be quickly drawn into the topsheet 10. Is possible.

  Moreover, since the center pressing part 81 and the 1st pressing part 85 are compressed toward the surface sheet side from the back sheet side, compared with the pressing part compressed from the surface sheet side from the back sheet side, it is a surface sheet. There is little damage caused by heat. For example, when the surface sheet is damaged by heat, the portion where the compressed portion is formed may be hardened more than necessary, or may be formed into a film and impair liquid permeability.

  However, since the center pressing part 81 and the 1st pressing part 85 are compressed toward the surface sheet 10 side from the back surface sheet 20 side, film formation of the surface sheet 10 can be suppressed. In particular, since the center pressing part 81 is arrange | positioned in the center area | region where most body fluids are discharged | emitted, it is desirable to ensure absorption performance. By suppressing the formation of the top sheet of the central pressing portion 81 formed in the central region from which the body fluid is discharged, liquid residue on the top sheet in the central region can be prevented, and deterioration of the wearer's wearing feeling can be suppressed. .

  Moreover, since the center pressing part 81 is arrange | positioned intermittently, the damage by the heat at the time of formation of a pressing part in a surface sheet is not formed continuously. For example, when the central squeezing part 81 is formed continuously, damage due to heat continues, so that it is difficult to draw the discharged body fluid into the surface sheet, and the body fluid may travel on the surface sheet. . However, since the surface sheet which has not received the damage by heat is arrange | positioned between the center pressing parts 81, it can prevent that a bodily fluid propagates on a surface sheet.

  For example, in the part where the central pressing parts 81 are continuously formed like the part on the back sheet side of the central pressing part 81 shown in FIG. 3, the interval between the central pressing parts 81 is narrowed, and the central pressing part 81 Are formed in a row. Thus, when the space | interval of the center pressing parts 81 becomes narrow, there exists a possibility that it may receive the damage by a heat not only in the part in which the center pressing part 81 was formed but the circumference | surroundings.

  If the continuous center pressing part 81 is squeezed from the surface sheet side, the surface sheet is formed into a film along the pressing line in which the center pressing part 81 is formed, and it becomes difficult to draw body fluid into the absorbent body. May be transmitted. However, like the present embodiment, by continuously pressing the central pressing portion 81 from the back sheet side, it is possible to suppress the surface sheet from being continuously formed into a film and to secure the body fluid drawability.

  Furthermore, the center pressing part 81 is formed only on the grid | lattice-like pressing line, and the center pressing part 81 is not formed in the area | region enclosed by the virtual pressing line. The region surrounded by the virtual pressing line is not damaged by the surface sheet due to heat, and body fluid can be drawn by the surface sheet of the region surrounded by the virtual pressing line. Furthermore, since the compression body is not formed and the volume is ensured, the absorber located in the lower part can hold | maintain the bodily fluid drawn in by the surface sheet.

  The density of the center pressing part 81 arrange | positioned at center area | region CA is lower than the density of the 1st pressing part arrange | positioned at the 1st area | region. Therefore, it becomes easy to secure the volume of the absorbent body in the central region where the absorption power is required, and the absorption performance in the central region can be secured. On the other hand, since the density of a pressing part is high in the 1st field, a fold base point increases. Therefore, deformation along the body can be performed.

  In addition, the density of the center pressing part 81 arrange | positioned at a center area | region is the area of the center pressing part 81 with respect to the area of a center area | region, and is the density of the 1st pressing part 85 arrange | positioned at 1st area | region FA. It is the area of the 1st pressing part 85 with respect to the area of a 1st area | region. The density of the center pressing part 81 arrange | positioned at center area | region CA and the density of the 1st pressing part 85 arrange | positioned at 1st area | region FA measure the area of the center area | region in a surface sheet, and are in a surface sheet, for example. The area of the formed central pressing part can be measured and measured by the ratio of the area of the central pressing part to the area of the central region. The density of the first pressing part 85 arranged in the first area FA can be measured by the same method.

  Moreover, the rigidity of the area | region enclosed by the virtual pressing line is lower than the rigidity of the part in which the pressing part was formed. Therefore, the touch in the center region can be improved and the wearing feeling can be improved. Furthermore, when viewed from the top sheet side, the central compressed portion 81 becomes less conspicuous than the longitudinal direction compressed portion compressed from the top sheet side, and can maintain a soft feeling of appearance.

  The longitudinal direction compression part 82 is arrange | positioned in the width direction outer side rather than the center pressing part 81, can suppress spreading | diffusion of the bodily fluid drawn in by the center pressing part 81 to the width direction outer side, and can prevent a side leak. .

  Since the longitudinal pressing part 82 is recessed from the top sheet side to the back sheet side, and the central pressing part 81 is recessed from the back sheet side to the top sheet side, the longitudinal pressing part 82 and the central pressing part are formed from one sheet side. Compared with the configuration in which the portion 81 is formed, the resistance to bending of the absorbent article can be increased.

  Furthermore, since the 1st width direction pressing part 83 and the 2nd width direction pressing part 84 are formed, when force is applied toward the width direction inner side from the width direction outer side, it becomes easy to maintain a shape. Moreover, since the longitudinal direction compression part and the width direction compression part comprise the cyclic | annular compression part continuously, and the central compression part 81 is surrounded by the cyclic | annular compression part, it is easy to maintain with the planar shape of a center area | region. It can be strong against the war.

  For example, when the pressing part extends in the width direction or extends in the longitudinal direction, the body fluid held by the pressing part may be diffused in the front-rear direction or the width direction. Especially the 1st pressing part 85 is arrange | positioned at the front side edge part of the absorber 30, and the rear side edge part of the absorber 30, and when a bodily fluid spread | diffuses too much, there exists a possibility that a front leak etc. may generate | occur | produce. However, since the 1st pressing part 85 is circular, it can suppress the spreading | diffusion of the hold | maintained bodily fluid and can prevent a leak.

  Next, a part of manufacturing method of the absorbent article which concerns on this embodiment is demonstrated. In addition, about the method which is not demonstrated below, the existing method can be used. The manufacturing method of an absorbent article is equipped with an absorber formation process, an absorber joining process, and a pressing process process at least.

  In the absorbent body formation step, for example, the absorbent body 30 is formed by molding a pulp as a material of the absorbent body with a molding drum. In the absorbent body joining step, the top sheet 10, the top side intermediate sheet 71, and the back side intermediate sheet 72 are joined to the molded absorbent body.

  A pressing process process squeezes the top sheet 10, the absorber 30, the surface side intermediate sheet 71, and the back surface side intermediate sheet 72, and forms a pressing part. At this time, it squeezes from the top sheet side toward the back sheet side to form the longitudinal direction pressing part 82, the first width direction pressing part 83, and the second width direction pressing part 84, and from the back sheet side to the top sheet. The center pressing part 81 and the 1st pressing part 85 are formed by giving a pressing process toward the side. The absorbent article 1 can be obtained by joining and cutting the back sheet to the absorbent body or the like thus configured.

(Second Embodiment)
Next, an absorbent article 1A according to the second embodiment will be described with reference to FIG. Note that in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

  The central pressing parts 81 of the absorbent article 1 </ b> A according to the second embodiment are not arranged in a lattice pattern, but are arranged at equal intervals similarly to the first pressing parts 85. Moreover, the density of the center pressing part 81 arrange | positioned at center area | region CA is comprised substantially the same as the density of the 1st pressing part arrange | positioned at 1st area | region FA.

  Since the density of the center pressing part 81 in the center area | region CA in 2nd Embodiment is higher than the density of the center pressing part 81 in the absorbent article 1 which concerns on 1st Embodiment, the rigidity of center area CA is raised and it is a plane. It becomes easy to arrange | position center area CA facing an excretion opening | mouth. In addition, by increasing the density of the central pressing portion 81 in the central area CA, a large number of folding base points can be provided and the body can be deformed along the body.

  Although the contents of the present invention have been disclosed through the embodiments of the present invention as described above, it should not be understood that the descriptions and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art.

  The pressing part should just be formed by pressing at least the surface sheet 10 and the absorber 30 in the thickness direction T, and various configurations can be adopted. For example, it can be formed by pressing or embossing, and the shape thereof may be a lattice network or a honeycomb shape.

  For example, the absorbent article according to the present embodiment is provided with a back-side intermediate sheet and a front-side intermediate sheet, but at least one of the back-side intermediate sheet and the front-side intermediate sheet is provided. Alternatively, none of them may be provided.
