Description

Absorbent article

The present invention relates to an absorbent article such as a sanitary napkin or the like, and relates to a lowered absorbent article which can suppress absorption performance after absorption of a body fluid.

Patent Document 1 describes a sanitary napkin having a liquid-permeable surface sheet, a liquid-impermeable back sheet, and an absorbent article disposed between the surface sheet and the back sheet, wherein the absorbent sheet is absorbed. The end portion of the absorbent body in the width direction of the sexual article has a sanitary napkin in which a compression region that compresses the compression portion of the absorbent body in the thickness direction of the absorbent article is formed. In the compressed region of the sanitary napkin of Patent Document 1, a squeezing groove that compresses the surface sheet and the absorbent body in the thickness direction together with the compressed portion is formed. Since the compression portion and the press groove are formed in the compression region of the end portion in the width direction of the absorber, the body fluid discharged from the drain port is absorbed by the compression portion and the press groove, thereby suppressing side leakage of the body fluid.

[Patent Document 1] Japanese Laid-Open Patent Publication No. 2009-125485 (Fig. 8, paragraph 0053, etc.)

However, the sanitary napkin described above has the following problems.

In the above-described sanitary napkin, a compressed region is provided at both end portions in the width direction of the absorbent body, and the absorbent body between the compressed regions is provided with an uncompressed region in which the compressed portion is not formed. The density of the absorber in the uncompressed region is lower than the density of the absorber in the compressed region. Comparing the non-compressed areas having a low density is more difficult to maintain the shape than the compressed area after absorbing the body fluid, and is easily deformed. When the absorber after absorbing the body fluid is deformed, the distance between the surface sheet disposed above the absorber and the absorber cannot be maintained constant. Therefore, since the surface sheet cannot smoothly move the body fluid to the absorbent body, there is a concern that the absorption performance is lowered.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a low-pressure absorbent article which can prevent side leakage of a body fluid and suppress deformation of an absorber after absorbing body fluid, and can suppress absorption performance.

In order to solve the above problems, the absorbent article of the present invention has a liquid-permeable surface sheet (surface sheet 10), a liquid-impermeable back sheet (back sheet 20), and a surface sheet and the aforementioned surface. An absorber (absorbent body 30) between the sheets, a compression portion (compression portion) that compresses the absorber in a thickness direction of the absorbent article, and a surface sheet that is compressed in a thickness direction in the thickness direction The absorbent article of the linear press portion (linear press portion 80) of the absorbent body is provided with a center including a discharge port abutting region facing the drain opening of the user, and is formed The first area of the compression unit (1st) a region A1) is disposed on both outer sides of the absorbent article in the width direction of the first region, and has a second region (second region A2) in which the compression portion is formed; and is disposed in the second region The second region is located in the third region (third region A3) on both outer sides in the width direction, and the linear press portion is formed to extend in the longitudinal direction of the absorbent article in the second region, and the third region is formed in the third region. The density of the absorber is lower than the density of the absorber in the first region, and is lower than the density of the absorber in the second region.

Since the first region including the center of the excretory opening abutment region is formed with the compressed portion formed by the compressed absorbent body, deformation of the absorbent body when the body fluid is absorbed can be suppressed as compared with the region where the compressed portion is not formed. Therefore, the unevenness of the distance between the surface sheet and the absorber is suppressed, and the distance between the surface sheet and the absorber is maintained substantially constant, and the decrease in the absorption performance after the body fluid is absorbed can be suppressed. In addition, the first region is less likely to be deformed after being biased from the outer side toward the inner side than the region having no compressed absorbent body, and is likely to be in a state in which the first region and the drain port are opposed to each other.

Moreover, the second region in which the compression portion and the linear press portion are formed is provided on the outer side in the width direction of the first region of the absorber. By providing the second region, the absorbed body fluid is held in the first region, and side leakage of the body fluid can be prevented.

Further, a third region having a lower density than the first region and the second region is provided on the outer side in the width direction of the second region. The absorber of the third region has a lower density than the first region or the like, and the user's legs and the like touch the width of the absorber. It is easily deformed to the sides. Therefore, it is possible to reduce the resistance of the user to the user when the user's leg or the like is pressed from the wide side to the wide side, and the user's feeling of attachment can be improved. Moreover, the deformation of the third region can improve the fit.

[Formation for carrying out the invention] (First embodiment)

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

The absorbent article 1 has a surface sheet 10 that abuts against the skin of the user, a liquid-impermeable back sheet 20 that is impermeable to liquid, 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 indicated by broken lines in FIGS. 1 and 2. The absorber 30 is disposed in a central portion of the absorbent article 1 in the longitudinal direction L and the width direction W.

The absorbent article 1 is viewed from a plane shown in FIG. 1 and has wing portions 43 and 44 provided outside the absorber 30 in a width direction W orthogonal to the longitudinal direction L. Further, the absorbent article 1 is provided on the side sheets 41 and 42 on the outer side of the absorbent body 30 in the width direction W.

The surface sheet 10 is a liquid-permeable sheet that transmits a liquid such as a body fluid. The surface sheet 10 covers at least the surface of the absorber 30. The surface sheet 10 is a permeate such as a non-woven fabric, a woven fabric, a perforated plastic sheet, or a mesh sheet. The flaky material of the body structure is not particularly limited. Any of natural fiber and chemical fiber can be used as the material of the woven fabric or the non-woven fabric.

The inner sheet 20 has substantially the same length as the length of the surface sheet 10. The inner sheet 20 may be a sheet of a polyethylene resin sheet, a laminated nonwoven fabric mainly composed of polypropylene or the like, an air-permeable resin film, a spun bond, or a nonwoven fabric such as a spunlace, and a sheet of an air-permeable resin film. The inner sheet 20 is preferably a material having flexibility to the extent that it does not cause discomfort during mounting. The inner sheet 20 is preferably liquid-impermeable and moisture-permeable, and can be formed, for example, by a microporous sheet obtained by subjecting an inorganic filler such as polyethylene or polypropylene to melt-kneading the inorganic filler.

The absorber 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 also be formed by laminating hydrophilic fibers or powders by a gas flow molding method, or by forming a hydrophilic sheet or a powder into a sheet-shaped air-laid sheet by a gas flow molding method, for example, a base paper (for example, basis weight) The pulverized pulp mixed with the superabsorbent polymer is disposed on 15 g/m ² ), and may be formed by wrapping a thin paper.

The absorbent body 30 of the embodiment of the present invention is constituted by a protective paper (not shown) in which pulp such as laminated pulp or synthetic pulp is wrapped. The protective paper is used to maintain the shape of the pulp, and for example, crepe paper, tissue paper, or the like can be used. The basis weight of the absorber core 31 (see, for example, FIG. 3) located at the center in the width direction of the absorber 30 is, for example, a higher basis weight of the absorber than the absorber core 31 on both sides in the width direction. Specifically, the basis weight of the absorbent core 31 is 100 to 800 g/m ² , and the absorber located around the absorber core 31 (for example, an absorber that is positioned further on both sides in the width direction than the absorber core 31) The basis weight is 100~500g/m ² .

The absorber 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 crotch spacing of an adult female, and is approximately 50 to 80 mm. The absorber 30 is followed by a sheet 20 by an adhesive such as hot melt. Further, in the embodiment of the present embodiment, the absorber 30 and the surface sheet 10 are followed by the hot-melt adhesive 60 (see Fig. 3).

The side sheets 41, 42 are disposed on both sides of the surface sheet 10. The side sheets 41, 42 can be selected from the same material as the surface sheet 10. However, in order to prevent menstrual blood from flowing outside the absorbent article 1 across the side sheets 41 and 42, it is desirable to have hydrophobicity or water repellency. The side sheets 41, 42 are a part covering the side edges of the absorber 30 and the wings 43, 44.

The absorbent article 30 is bonded to the periphery of the surface sheet 10, the side sheets 41, 42 and the back sheet 20, and the absorber 30 is sealed. As a method of joining the surface sheet 10 and the back sheet 20, either a hot embossing process, an ultrasonic wave, or a hot-melt adhesive may be used, or a plurality of types may be combined.

In the inner sheet 20, an adhesive 50 is applied to a plurality of regions on the surface in contact with the undergarment (see Fig. 2). The adhesive 50 is intermittently disposed along the longitudinal direction L on the back side of the absorber. Adhesive 50 is also provided on the surface of the wing portion 43 and the wing portion 44 that is in contact with the undergarment. The adhesive 50 is in contact with the release sheet 90 in a state before use. The release sheet 90 is a case where the deterioration of the adhesive 50 before use is prevented. Moreover, the release sheet 90 is peeled off by the user during use.

In addition, in an absorbent article that does not have the release sheet 90, It is also possible to prevent the deterioration of the adhesive before use by packaging the packaging sheet of the absorbent article. When the adhesive is in contact with the packaging sheet, it is desirable to apply a treatment for peeling off the adhesive on the surface of the packaging sheet without lowering the adhesive force of the adhesive.

The surface sheet 10 is formed with a surface sheet press portion 11 that compresses the surface sheet in the thickness direction. The surface sheet press portion 11 is arranged in a lattice shape. In the absorber 30, a compression portion 70 that is compressed in the thickness direction is formed. The absorbent article 1 is formed with a linear press portion 80 that compresses the surface sheet 10 and the absorbent body 30 in the thickness direction.

The compression unit 70 includes a first compression unit 71 formed at a distal end portion of the absorber, a second compression unit 72 formed at a rear side of the first compression unit 71 in a second region A2 to be described later, and an absorbent body 30. The third compression portion 73 of the rear end portion.

The first compression portion 71 is formed at the distal end portion of the absorber 30 in the entire width direction of the absorber. The outer shape of the distal end of the first compression portion 71 is along the outer shape of the distal end of the absorbent body, and has an arc shape extending in the convex wide direction on the front side.

The second compression unit 72 extends rearward from the rear end of the first compression unit 71 . The front end and the rear end of the second compression portion 72 are located at the end portion in the width direction of the absorber 30. The center of the second compression portion 72 in the longitudinal direction is positioned further inward in the width direction than the front end and the rear end of the second compression portion 72. The shape of the second compressed portion 72 is an arc shape extending inward in the longitudinal direction of the convex shape in the width direction.

The third compression portion 73 is formed at the rear end portion of the absorber 30 in the entire width direction of the absorber 30. The outer shape of the rear end of the third compression portion 73 is formed along the outer shape of the rear end of the absorber 30, and the width direction of the rear side is convex. Extended arc shape.

The linear press portion 80 has a first linear press portion 81 that is formed from the first compressed portion 71 across the second compressed portion 72, and extends rearward from the rear end of the first linear press portion 81 in the width direction. The second linear press portion 82 that extends rearward from the rear end of the second linear press portion 82 toward the rear in the width direction, and the third linear press portion 83 from the third linear press portion 83 The rear end is further provided with a fourth linear press portion 84 that extends rearward in the width direction outer side.

Further, the linear press portion 80 may be formed by pressing the surface sheet 10 and the absorber 30 at least in the thickness direction T to form a continuous line in a predetermined direction, and various configurations may be employed. For example, it can be formed by press working or embossing, and its shape can also be a lattice mesh or a honeycomb shape.

In the width direction W, the absorbent article 1 includes a first region A1 including a center of a discharge port abutting region facing the drain port of the user, and is disposed on both sides in the width direction of the first region A1. The second region A2 of the square; and the third region A3 disposed on both sides in the width direction than the second region A2.

The absorbent article 1 includes, in the longitudinal direction L, a central region B1 including a center of a discharge port abutting region facing the drain opening of the user, and a front region B2 disposed further forward than the central region; It is disposed in the rear side region B3 which is located further rearward than the central region.

The center of the excretory opening abutment area means the center of the longitudinal direction L and the width direction W of the area where the user's excretory opening abuts. For example, in the absorbent article 1 having the wings 43, 44, the center of the longitudinal direction L of the wings 43 and 44 is The center of the long direction L of the area where the drain port abuts. Further, in the absorbent article 1 having no wings 43 and 44, the position where the length dimension of the absorbent body in the width direction is the shortest is the center in the longitudinal direction of the excretory opening abutment region.

The absorber core 31 is disposed in the first region A1. In the first region A1, the first compression portion 71 that compresses the absorber 30 in the thickness direction is formed as a whole. The first compression unit 71 is disposed at the center in the width direction of the first area A1. The first compression unit 71 is disposed only in the central portion B1 in the longitudinal direction L, and is not disposed in the front side region B2 and the rear side region B3. The first region A1 is a region in which the first compression portion that compresses the absorber in the thickness direction is formed. The first region has a higher density structure than the region of the absorber where the compression portion is not formed.

In the second region A2, a second compressed portion 72 that compresses the absorber 30 in the thickness direction T and a linear press portion 80 that compresses the absorber 30 and the surface sheet 10 in the thickness direction T are formed. The second compression unit 72 is disposed across the front side area B2 and the rear side area B3 around the center area B1 in the longitudinal direction L. The second region A2 is a region in which the second compressed portion 72 that compresses the absorber in the thickness direction is formed.

The third area A3 is a region outside the second region in the width direction. The third region A3 is an uncompressed region in which the absorber 30 is not compressed in the thickness direction T. That is, the linear press portion 80 and the compressing portion 70 are not formed in the third region A3. Therefore, the third region A3 is more bulky than the first compressed portion of the first region A1 and the second compressed portion of the second region A2, and the density of the absorber 30 in the third region A3 is higher than that of the first region A1. The density of 30 is lower and is lower than the density of the absorber 30 in the second region A2.

In addition, the third region A3 is a region in which the density of the absorber 30 is lower than the density of the absorber 30 in the first region A1, and is smaller than the density of the absorber 30 in the second region A2. For example, the concept of compressing the region of the absorber 30 during the manufacturing process of the absorber 30 is also included.

Since the first region A1 including the center of the excretory opening abutment region has the compression absorbent body 30, the absorption shape at the time of absorbing the body fluid can be suppressed as compared with the region where the absorbent body 30 is not compressed. Therefore, the unevenness of the distance between the surface sheet 10 and the absorber 30 is suppressed, and the decrease in the absorption performance after the body fluid is absorbed can be suppressed. Therefore, it is easy to maintain long-term absorption performance.

On the other hand, the second region A2 in which the compression portion 70 and the linear press portion 80 are formed is provided on the outer side in the width direction of the first region A1 of the absorber 30. The body fluid absorbed in the first region A1 can be held in the second region A2, and side leakage of the body fluid can be prevented.

Further, a third region having a lower density than the first region A1 and the second region A2 is provided on the outer side in the width direction of the second region A2. The absorber density in the third region is lower than that in the first region A1 or the like, and the user's legs and the like are easily deformed after hitting both sides in the width direction of the absorber. Therefore, it is possible to reduce the resistance to the user when the user's leg or the like is pressed from the outer side in the width direction to the inner side in the wide direction, and the user's feeling of attachment can be improved, and the fit can be improved. Further, since the density of the third region is lower than that of the second region, the body fluid sucked in the second region is less likely to migrate to the third region side. By providing the third region on both sides in the width direction of the second region, side leakage of the body fluid can be prevented.

Further, the second region A2 is a center intersection point EP that intersects the center of the excretion port abutment region and intersects the center imaginary line EL along the width direction. A curved shape that widens toward the outer side in the width direction of the outer side of the absorbent article.

The leg of the user is present on the outer side in the width direction opposite to the contact area of the excretory opening, and the shape of the leg is curved in a convex shape toward the inner side in the width direction. By making the second region A2 curved from the first intersection point toward the outer side in the longitudinal direction of the absorbent article in the width direction, the second region A2 is placed along the shape of the leg, and the adhesion can be improved.

Further, in the embodiment of the present embodiment, the shape of the second region A2 is a curved shape that widens toward the outer side in the width direction from the center intersection point EP toward the outer side in the longitudinal direction of the absorbent article, but is not limited thereto. Specifically, the shape of the second region A2 may be, for example, a linear shape extending in the longitudinal direction, or an elliptical or rectangular shape extending in the longitudinal direction.

In addition, the length of the second region A2 in the width direction is longer than the length of the first linear press portion 81 formed in the second region in the width direction. The linear press portion 80 is a deformation base point when it is subjected to the side pressure between the turns. However, the linear press portion 80 is rigid from the surface sheet 10 to the absorber 30, and the rigidity of the portion where the linear press portion 80 is formed is higher than that in the region where only the absorber 30 is pressed. Therefore, when the width of the linear press portion 80 is widened, the rigidity of the entire absorbent body is increased, and the feeling of use may be deteriorated.

By widening the width of the second region A2 to be longer than the width of the first linear press portion 81, the deformation base point can be more clearly set by the second region A2, and the first line can be shortened. The width of the press portion 81 can suppress the case where the rigidity becomes too high.

Further, in the embodiment of the present embodiment, the width of the second region A2 is longer than the width of the first linear press portion 81, but the configuration is not limited thereto. Specifically, the width of the second region A2 may be the same as the width of the first linear press portion 81 or may be shorter than the width of the first linear press portion 81.

Moreover, the length of the longitudinal direction L of the second region A2 is longer than the length of the longitudinal direction L of the first region A1. The first region A1 may be provided in the vicinity of the drain port where the body fluid is most easily discharged. On the other hand, since the second region A2 serves as a base point for deformation, it is desirable to provide the vicinity of the leg opening along the longitudinal direction L. Therefore, one of the second regions A2 is formed longer than the first region A1 in the long direction, and it is easy to adhere to the body while ensuring the absorption performance.

Further, in the embodiment of the present embodiment, the length of the second region A2 in the longitudinal direction is longer than the length of the first region A1 in the longitudinal direction, but the configuration is not limited thereto. Specifically, the length in the longitudinal direction of the second region A2 may be the same length as the length in the longitudinal direction of the first region A1, and may be shorter than the length in the longitudinal direction of the first region A1.

Further, the first wide-direction imaginary line EW1 that passes through the front end portion of the first region A1 and extends in the width direction W, and the second wide direction that extends through the rear end portion of the first region A1 and that extends in the width direction W are formed. The linear press portion 80 between the imaginary lines EW2 has a curved shape along the second region A2.

The first region A1 includes the center of the excretory opening abutment region, and is the region in which the absorbent body 30 can be most attached to the body. The linear press portion 80 which is positioned outside the first region A1 in the width direction is formed along the curved shape of the second region A2, thereby providing a deformation base point along the outer shape of the leg, and suctioning The body 30 fits on the body.

In addition, in the embodiment of the present embodiment, the linear press portion located outside the first region A1 of the first linear press portion 81 in the width direction is formed along the shape of the second region A2, but is not limited thereto. This composition.

The fourth area A4 is provided on the inner side in the width direction of the second area A2 and in the rear side in the longer direction than the first area A1. The fourth region A4 is an uncompressed region in which the absorber 30 is not compressed in the thickness direction. That is, the linear press portion 80 and the compressing portion 70 are not formed in the fourth region A4. Therefore, the fourth region A4 is more bulky than the first compressed portion of the first region A1 and the second compressed portion of the second region A2, and the density of the absorber in the fourth region is higher than that of the absorber in the first region A1. The density is lower and is lower than the density of the absorber in the second region A2.

Further, the fourth region A4 may be a region in which the density of the absorber 30 is lower than the density of the absorber 30 in the first region A1 and is lower than the density of the absorber 30 in the second region A2, for example. The concept of compressing the area of the absorber in the manufacturing process of the absorber 30 is also included.

In addition, since the density of the absorber in the second region A2 is higher than the density of the absorber in the fourth region A4, the second region A2 can be deformed as a base point after being biased from the outside in the width direction to the outside in the width direction. Since the density of the absorber 30 in the fourth region A4 is lower than the density of the absorber 30 in the first region A1, the absorber 30 disposed behind the first region A1 is easily deformed and can be absorbed along the body. Body 30. For example, when the fourth region A4 is pressed from the outer side in the width direction toward the inner side in the width direction, the fourth region A4 is deformed toward the user side, and can be positioned more than the central region B1. The fourth region A4 at the rear protrudes toward the body side, and the absorbent body is disposed between the gaps of the body to prevent back leakage.

Further, in the embodiment of the present embodiment, the fourth region A4 is formed, but the configuration is not limited thereto. Specifically, a region having the same density as the first region A1 and a region having a higher density than the first region A1 may be provided behind the first region A1.

Further, the density of the absorber 30 in the second region A2 is higher than the density of the absorber 30 in the first region A1. Since the density of the absorber 30 in the second region A2 is higher than the density of the absorber 30 in the first region A1, when the outer region is pressed from the width direction, the second region A2 and the linear press portion are deformed as a base point. Can improve the fit of the user. On the other hand, when the density of the first region A1 is too high, the inhalation of the body fluid is lowered. However, since the density of the second region A2 is higher than the density of the first region A1, the adhesion can be improved while maintaining the inhalability of the body fluid.

Further, in the embodiment of the present embodiment, the density of the absorber in the second region A2 is higher than the density of the absorber in the first region A1, but the configuration is not limited thereto. Specifically, the density of the absorber in the second region A2 may be the same as the density of the absorber in the first region A1, or may be lower than the density of the absorber in the first region A1. For example, when the absorbent body is produced, the thickness of the absorbent body is formed almost uniformly, and the first compressed portion and the second compressed portion may be formed, or the thickness of the absorbent body corresponding to the first region may be formed to be thicker. The first compressed portion and the second compressed portion may be formed to have the same thickness as the first region and the second region. Forming the first compression portion and In the absorber of the second compression portion, the density of the first region is higher than the density of the second region.

Further, the density of the absorber 30 in the first region A1, the second region A2, and the third region A3 is the highest in the second region A2, and the density in the first region A1 is high, and the density in the third region A3 is the lowest. Ideal. Further, the density of the absorber 30 in the first region A1, the second region A2, and the fourth region A4 is the highest in the second region A2, and the density in the first region A1 is high, and the density in the fourth region A4 is high. The minimum is ideal.

Further, the basis weight and density of the absorber 30 can be measured, for example, by the following measurement method. The absorbent article packaged by the package is opened, and the folded absorbent article is unfolded, and the thickness and the measurement area of the portion of the basis weight and the density are measured. Next, the portion where the basis weight and the density were measured was cut out from the absorbent article, and the weight of the cut portion was measured. Next, portions other than the absorber such as the surface sheet and the back sheet were removed from the cut portions, and the weight of the absorber was measured. The basis weight is calculated based on the weight of the absorbent body and the area of the portion where the basis weight and density are measured. The density is calculated based on the basis weight and thickness.

Further, the thickness can be measured by the following measurement method. Specifically, the absorbent article of the sample was immersed in liquid nitrogen and frozen, and then cut with a razor, returned to normal temperature, and then measured with an electron microscope (for example, Keynes VE7800) at a magnification of 50 times. Here, the reason why the absorbent article of the sample is frozen is to prevent variation in thickness due to compression at the time of cutting.

Next, a method of manufacturing the absorbent article 1 of the first embodiment Part of the description. In addition, the original method can be used for the method not described. In the method for producing an absorbent article, a surface sheet forming process is performed as the first step. Specifically, the surface sheet is subjected to compression processing in the thickness direction T to form the surface sheet press portion 11. This compression processing is, for example, an embossing roll that heats and presses the surface sheet 10 to form a lattice-like uneven process.

Next, a surface sheet bonding process is performed as the second step. Specifically, the surface sheet and the side sheets 41, 42 are bonded, for example, by heat fusion.

The absorber molding process was carried out as the third step. Specifically, after the pulp which is a material of the absorber is laminated by the forming drum, the laminated pulp is wrapped by a protective paper such as a thin paper. Then, the absorbent body wrapped by the protective paper is compressed in the thickness direction to form a compressed portion. Further, the steps of manufacturing the surface sheet of the first step and the second step, and the order of the absorber forming process of the third step may be reversed.

In the fourth step, the joining process is performed. Specifically, the joining of the absorber formed in the third step and the surface sheet and the side sheet joined in the second step is performed.

The pressing process is carried out in the fifth step. Specifically, the absorbent body 30 and the surface sheet 10 are compressed in the thickness direction to form a linear press portion 80. At this time, since the second compressing portion is formed in advance in the absorber 30 in the second region, the floating of the absorber of the surface sheet is less likely to occur, and the linear press portion can be easily formed.

In the sixth step, the inner sheet bonding work is performed. Specifically, the absorbent body, the surface sheet, and the like which form the linear press portion are joined to the inner sheet. After bonding the inner sheet, there is a work of applying an adhesive. The absorbent article of the embodiment of the present embodiment can be produced by the above-described work.

(Second embodiment)

Next, the absorbent article 1A of the second embodiment will be described with reference to Fig. 4 . In the following description of the embodiment, only the configuration that is different from the first embodiment will be described, and the same components as those of the first embodiment will be denoted by the same reference numerals and will not be described.

In the absorbent article 1A of the second embodiment, the shapes of the second region A2 and the third region A3 and the shape of the linear press portion are different. The second region A2 of the absorbent article 1A has a linear shape extending in the longitudinal direction L on both sides in the width direction of the first region A1. The first area A1 and the second area A2 are adjacent to each other in the width direction W. The linear press portion 80 is a vertically long circular shape and has an inner linear press portion 85 and an outer linear press portion 86 that is located outside the inner linear press portion. A part of the inner linear press portion 85 and the outer linear press portion 86 is disposed in the second region A2. Further, the third region A3 is a linear shape extending in the longitudinal direction L on both sides in the width direction of the second region A2.

(Third embodiment)

Next, an absorbent article 1B according to a third embodiment will be described with reference to Fig. 5 . The absorbent article 1B of the third embodiment differs from the shape of the first region A1, the second region A2, and the third region A3 of the absorbent article 1 of the first embodiment and the shape of the absorbent body 30.
