  However, the above-described absorbent article has the following problems.

  Since the rear flap portion of the absorbent article described in Patent Document 1 includes the flap portion absorber, the rigidity is likely to be higher than that of a configuration that does not include the flap portion absorber. Furthermore, since the rear flap portion is provided with an embossed portion, the rigidity of the rear flap portion is likely to be further increased. A plurality of embossed portions are provided side by side in the width direction. Therefore, when the absorbent article is pressed from the outer side in the width direction to the inner side in the width direction by the wearer's legs and buttocks, the rear flap part is hardly deformed, and there is a possibility that an uncomfortable feeling may occur.

  Moreover, since the rigidity of the rear flap is relatively high, the rear flap may not be properly disposed along the roundness of the body. Therefore, the sanitary napkin does not fit the body, body fluid leaks, and the wearing feeling may be deteriorated. Further, since the rear flap portion is hard, for example, when a crease or crease is formed, the hard crease or crease hits the wearer, and the wearing feeling may deteriorate.

  The present invention has been made in view of the above-described problems, and is an absorbent article that can suppress wrinkles and kinks of the flap portion during wearing, and can be disposed along the wearer's body to suppress deterioration in wearing feeling. The purpose is to provide.

  In order to solve the problems described above, an absorbent article according to the present invention is an absorbent article having a front-rear direction (longitudinal direction L) and a width direction (width direction W) orthogonal to the front-rear direction. A main body portion (main body portion 2) having (main body absorber 30), a wing portion (wing portion 43) that protrudes outward in the width direction from the main body portion and is folded back to the non-skin contact surface side of the wearer's underwear; A flap portion (flap portion 60) that protrudes outward in the width direction from the main body portion behind the wing portion, and the flap portion includes a flap absorber (flap absorber 35) and the flap. A flap surface sheet (flap surface sheet 12) positioned closer to the skin contact surface than the absorbent body, and the flap absorber and the flap surface sheet are squeezed in the thickness direction in the flap portion. Wrap embossed portions and (flap embossed portion 70) is formed, said flap embossed portion is summarized in that extending from the inner side in the width direction toward the rear outward in the width direction.

  In a state before use, the adhesive is in contact with a release sheet (not shown). The release sheet prevents the adhesive from deteriorating before use. And a peeling sheet peels by a wearer at the time of use.

  In addition, in the absorbent article which does not have a peeling sheet, you may be comprised so that it may prevent that an adhesive agent deteriorates before use with the packaging sheet which wraps an absorbent article separately. When the adhesive is in contact with the packaging sheet, it is desirable that the surface of the packaging sheet be subjected to a treatment that allows the adhesive to be peeled without reducing the adhesive strength of the adhesive.

  The absorbent article 1 is formed with a main body embossed portion 80 obtained by compressing the topsheet 10 and the main body absorber 30 in the thickness direction, and a flap embossed portion 70 obtained by pressing the topsheet and the flap absorber in the thickness direction. . The main body embossed portion 80 and the flap embossed portion 70 are formed by pressing at least the top sheet 10 and the main body absorbent in the thickness direction T, or at least pressing the top sheet 10 and the flap absorbent in the thickness direction T. What is necessary is just to employ | adopt various structures. For example, it can be formed by pressing or embossing, and the shape thereof may be a lattice network or a honeycomb shape.

  The flap portion 60 is formed with a plurality of constricted portions in which the length in the width direction is shorter than the length in the width direction of the front and rear regions thereof. The constricted portion includes a first constricted portion 61 located on the front side and a second constricted portion 62 located on the rear side.

  The flap portion 60 includes a first flap portion 63 located on the front side of the first constricted portion 61 and a second flap portion located behind the first constricted portion 61 and ahead of the second constricted portion 62. 64 and a third flap portion 65 located rearward of the second constricted portion 62.

  The first flap portion 63 is a region from the rear inner end portion 43RI located at the rear to the first constricted portion 61 among the inner end portions in the width direction of the wing portion 43, and is directed rearward from the rear inner end portion 43RI. As it extends outward in the width direction. The first maximum width position (outer end portion) 63WM located on the outermost side in the width direction in the first flap portion 63 is located on the outer side in the width direction than the first constricted portion 61. The first maximum width position 63WM is located behind the center of the first flap 63 in the front-rear direction.

  The second flap portion 64 is a region from the first constricted portion 61 to the second constricted portion 62 that becomes the rear end portion of the first flap portion 63, and extends outward in the width direction from the first constricted portion 61 toward the rear. . The second maximum width position (outer end portion) 64WM located on the outermost side in the width direction in the second flap portion 64 is located on the outer side in the width direction than the second constricted portion 62. The second maximum width position 64WM is located behind the center of the second flap portion 64 in the front-rear direction.

  The third flap portion 65 is a region from the second constricted portion, which is the rear end portion of the second flap portion 64, to the rear end portion of the flap portion, and outwards in the width direction from the second constricted portion 62 toward the rear. Extend. The third maximum width position (outer end portion) 65WM located on the outermost side in the width direction in the third flap portion 65 is located on the outer side in the width direction than the second constricted portion 62. The third maximum width position 65WM is located behind the center of the third flap portion 65 in the front-rear direction.

  Next, the flap embossed portion will be described in detail. The flap embossed portion includes a first flap embossed portion 71 extending rearward from the vicinity of the rear inner end portion 43RI of the wing portion 43, and a second flap branching from the first flap embossed portion 71 and extending toward the first constricted portion 61. Branching from the embossed portion 72 and the first flap embossed portion 71 and branching from the third flap embossed portion 73 extending toward the second constricted portion 62 and the first flap embossed portion 71, the width direction of the third flap portion 65 And a fourth flap embossed portion 74 extending toward the vicinity of the third maximum width device 65WM located outside. The flap embossed portion 70 is formed in a region where the flap absorber 35 is disposed.

  According to the absorbent article configured as described above, since the flap absorbent body is included, body fluid can be absorbed also in the flap portion, and rear leakage and side leakage can be suppressed. For example, in a sleeping posture or the like, menstrual blood or the like may leak from a gap between the buttocks and the absorbent article. However, since the flap absorber 35 is provided in the flap part 60, a rear leak etc. can be suppressed.

  Moreover, since the flap absorber 35 is provided in the flap part 60, the rigidity of a flap part becomes high and there exists a possibility that a flap part may become difficult to deform | transform. However, since the 2nd flap embossed part 72, the 3rd flap embossed part 73, and the 4th flap embossed part 74 are constituted so that it may extend from the width direction inner side to the width direction outer side toward the back, the flap embossed part is In order to follow the direction in which the force is applied, the flap embossed portion becomes the folding start point, and the flap portion is naturally folded. Therefore, it becomes easy to fit the flap part 60 to the body and the underwear without difficulty. Therefore, disordered wrinkles are unlikely to occur in the flap portion, a deformation without a sense of incongruity can be achieved, and a clean wearing feeling can be obtained.

  The flap embossing part is comprised by the some embossing structure part squeezed in the thickness direction. Specifically, the 2nd flap embossing part 72, the 3rd flap embossing part 73, and the 4th flap embossing part 74 are comprised by the aggregate | assembly of several point-like embossing structure parts. The dot-like embossing components are arranged in a line and are not continuous with each other. According to the aggregate | assembly of a some dot-shaped embossing structure part, it can suppress that a flap part becomes too hard by the embossing structure part compared with the embossing structure part which continues in a line form. Therefore, it becomes easy to deform | transform a flap part flexibly along a line of a body, and can make a flap part fit a body more.

  Moreover, the 1st flap embossing part is extended along the longitudinal direction, and is provided so that it may connect from the rear side edge part of the wing part 43 to the rear side edge part of a flap part. Therefore, when body fluid diffuses from the center in the width direction of the absorbent article toward the outside in the width direction, the body fluid is drawn in the first flap embossed portion, and the body fluid diffuses outward in the width direction from the first flap embossed portion. Can be suppressed.

    In addition, a plurality of flap embossed portions are arranged in the width direction. Specifically, the first flap embossed portion overlaps the second flap embossed portion, the third flap embossed portion, and the fourth flap embossed portion in the width direction. The second flap embossed portion overlaps the first flap embossed portion and the third flap embossed portion in the width direction. The third flap embossed portion overlaps the first flap embossed portion, the second flap embossed portion, and the fourth flap embossed portion in the width direction.

  Since the flap embossed portion overlaps in the width direction, the first flap embossed portion, the second flap embossed portion 72, the third flap embossed portion when body fluid flows from the widthwise center of the absorbent article to the widthwise outer side. 73 and the 4th flap embossing part 74 can draw a bodily fluid by double and triple, and can prevent a bodily fluid from reaching the outer edge of an absorbent article.

  Moreover, since the 1st flap embossing part 71 is extended along the longitudinal direction from the vicinity of the rear side edge part of the wing part 43, it is pressed by the wearer's leg from the width direction outer side to the width direction inner side in the vicinity of the wing part. When this occurs, it becomes the deformation base point. Since the plurality of flap embossed portions are provided by branching from the first flap embossed portion 71, even if the wing portion 43 is largely deformed, the plurality of flap embossed portions can be deformed from the base point, and the flap portion The whole can be deformed flexibly.

  The first flap embossed portion 71 is rearward of the rear end portion of the wing portion 43 and is separated from the rear end portion of the wing portion 43, but is not limited to this configuration. The 1st flap embossing part 71 may be extended toward back from the rear side edge part of the wing part 43, for example.

  Outer edge embossed portions 85 are provided on the outer edges of both ends in the width direction of the absorbent article. The outer edge embossed portion 85 is composed of a plurality of embossed components that are squeezed in the thickness direction. Specifically, the outer edge embossed portion 85 is constituted by an aggregate of a plurality of point-like embossed constituent portions. The dot-like embossing components are arranged in a line and are not continuous with each other.

  The dot-like embossed component constituting the outer edge embossed portion is configured to have a different shape or depth from the dot-like embossed component constituting the flap embossed portion. Specifically, the area of the embossing component that constitutes the flap embossing portion is larger than the area of the dot-like embossing component that constitutes the outer edge embossing portion. Or the depth of the dotted | punctate embossing structure part which comprises a flap embossing part is deeper than the depth of the dotted | punctate embossing structure part which comprises an outer edge embossing part.

  Since it arrange | positions so that a flap embossing part may continue substantially inside an outer edge embossing part, it can prevent that a bodily fluid flows into the outer edge of an absorbent article. In addition, the user can clearly see the second flap embossed portion 72, the third flap embossed portion 73, and the fourth flap embossed portion 74, and the flap embossed portion capable of drawing body fluid is more than the outer edge of the absorbent article. It can be recognized that it is present inside, and a sense of security that side leakage hardly occurs can be obtained.

  Furthermore, the embossing structure part which comprises a flap embossing part has a larger area or depth than the embossing structure part which comprises an outer edge embossing part, and is conspicuous. Therefore, the flap embossed portion can be made relatively conspicuous. The user can easily notice the flap embossed portion that prevents side leakage inside the outer edge of the absorbent article, and can obtain a sense of security.

  Moreover, it is desirable that the shape of the embossing component that constitutes the flap embossed portion is different from the shape of the embossed component that constitutes the outer edge embossed portion. Note that the difference in the shape of the embossing component is a concept including not only a configuration having different outer shapes, such as a circular shape and a triangular shape, but also a similar shape having the same shape but different sizes. The flap embossed part that can draw in body fluid is located inside the outer edge of the absorbent article by making the shape of the embossed part constituting the flap embossed part different from the shape of the embossed part constituting the outer edge embossed part. Can be recognized and a sense of security that side leakage hardly occurs.

  The outer edge embossed portion and the flap embossed portion are arranged with a space therebetween. For example, if the outer edge embossed portion and the flap embossed portion are continuous, the body fluid drawn by the flap embossed portion may propagate to the outer edge embossed portion. However, since the outer edge embossed part and the flap embossed part are separated from each other, the body fluid drawn by the flap embossed part can be prevented from propagating to the outer edge embossed part, and the leakage of the body fluid can be suppressed.

  Next, a part of manufacturing method of the absorbent article 1 according to the first embodiment will be described. In addition, about the method which is not demonstrated, the existing method can be used. The manufacturing method of an absorbent article performs a surface sheet production | generation process as a 1st step. Next, as a second step, a surface sheet joining step is performed. Specifically, the main body surface sheet 11 and the flap surface sheet 12 are bonded by, for example, heat welding.

  As a third step, an absorber molding process is performed. Specifically, the main body absorbent body and the flap absorbent body are formed by molding pulp as a material of the absorbent body with a molding drum. In addition, a reverse order may be sufficient as the order of the manufacturing process of the surface sheet of a 1st step and a 2nd step, and the absorber molding process of a 3rd step.

  In the fourth step, a joining process is performed. Specifically, a joining process is performed for joining the main body absorbent body and the flap absorbent body molded in the third step, and the top sheet and the side sheet joined in the second step.

  In the fifth step, a pressing process is performed. Specifically, the main body absorbent body and the topsheet 10 are compressed in the thickness direction to form the main body embossed portion 80, and the flap topsheet 12 and the flap absorber 35 are compressed in the thickness direction, and the flap embossed portion 70 is compressed. Form. In the sixth step, a back sheet joining step is performed. Specifically, the absorber, the top sheet, and the like on which the embossed portion is formed are joined to the back sheet. After the above steps, a step of forming the outer edge embossed portion 85 and a step of applying an adhesive are provided. The absorbent article which concerns on this Embodiment can be manufactured according to said process.

  Next, an absorbent article 1A according to Modification 1 will be described. FIG. 5 is a plan view seen from a part of the surface side of the absorbent article 1A according to the first modification. The absorbent article shown in FIG. 5 has a graphic embossing component 91 in which the embossing component constituting the embossed flap portion shows a graphic shape, and a pattern embossing component 92 showing a pattern shape.

  The figure embossing structure part 91 is an embossing part which shows a figure shape. In addition, the figure shape is a concept including polygons such as points, lines, circles, triangles, and rectangles. The pattern embossing configuration part 92 is an embossing part indicating a pattern shape. The pattern shape is a concept including various patterns and pictures such as a star pattern, a heart pattern, a leaf pattern, and a floral pattern.

  The aesthetic appearance can be enhanced by having the pattern embossing component 92. Furthermore, the absorbent article 1A can be decorated in a cute manner, and the user's feeling of depression during menstruation can be alleviated. Furthermore, the pattern embossing component 92 is more conspicuous than the line-shaped embossed portion, and the user can recognize that there is an embossed portion that absorbs bodily fluids inside the outer edge embossed portion 85. Therefore, the user can obtain a sense of security against side leakage more.

The area of the pattern embossed structure portion 92 is larger than the area of FIG shaped embossed structure portion 91. Therefore, pattern embossed structure portion 92, conspicuous than FIG shaped embossed structure portion 91 plays a role of a mark. For example, when menstrual blood diffuses in the flap portion 60, the flap embossed portion draws menstrual blood and spreads. At that time, menstrual blood oozes into the pattern embossing component having a relatively large area, so that the user can visually recognize the pattern embossing component in which menstrual blood has oozed and judge the replacement time.

  The graphic embossing component 91 is arranged on a predetermined line, and the pattern embossing component is arranged offset from the line. The line is a concept including not only a straight line but also a curved line. By arranging the graphic embossing component 91 on a predetermined line, the graphic embossing component 91 can be arranged densely, and body fluid can be drawn in the graphic embossing component to prevent side leakage. In addition, by disposing the pattern embossing component 92 away from the line where the graphic embossing component 91 is disposed, the pattern embossing component 92 can be made conspicuous, and the aesthetics can be enhanced while ensuring the side leakage prevention function. be able to.

  The width dimension W92 orthogonal to the predetermined line of the pattern embossing component 92 is larger than the width W91 of the predetermined line. Since the width dimension orthogonal to the predetermined line of the pattern embossing component 92 is larger than the width of the line where the figure embossing component 91 is arranged, the pattern embossing component 92 can be made conspicuous and the aesthetics can be enhanced. . Moreover, since the area of the pattern embossing component 92 is large, even if body fluid penetrates the entire pattern embossing component 91, the body fluid may not penetrate the entire pattern embossing component 92. The replacement time can be grasped by the unit 92.

  Moreover, if the pattern embossing structure part 92 has shifted | deviated from the line in which the figure embossing structure part 91 is arrange | positioned, a deformation | transformation of a flap part can be stopped by the part in which the figure embossing structure part 91 is arrange | positioned. Specifically, when the flap portion is deformed with the vicinity of the base of the wing portion as a base point, the figure embossed portion arranged in a certain line shape becomes the deformation base point. At this time, the deformation of the flap portion is likely to stop at the place where the pattern embossing configuration portion deviated from the line of the graphic embossing configuration portion is disposed, and excessive deformation of the flap portion can be suppressed. When the width of the pattern embossing component 92 is larger than the width of the graphic embossing component 91, the pattern embossing component 92 jumps out of the line where the graphic embossing component 91 is arranged, and the effect of suppressing deformation of the flap portion is obtained. Can be obtained.

Further, the pattern embossed structure portion is preferably disposed to the rear than line of FIG shaped embossed structure portion. Pattern embossed structure portion, when disposed behind the line of FIG shaped embossed structure portion, when the deformed flap portion from the wing portion located in front, suppressing the deformation being transmitted toward the rear it can.

  A plurality of graphic embossing components 91 are arranged adjacent to each other, and the pattern embossing components 92 are arranged between the graphic embossing components 91. The interval P1 between the pattern embossing component 92 and the graphic embossing component 91 is larger than the interval P2 between the graphic embossing components 91. By making the interval between the pattern embossing component 92 and the graphic embossing component 91 larger than the interval between the graphic embossing components 91, the pattern embossing component 92 can be made conspicuous and the aesthetic appearance can be enhanced.

  Moreover, the embossing structure part which comprises an outer edge embossing part may contain the pattern embossing structure part 92. FIG. However, in order to prevent the outer edge of the absorbent article from opening, it is desirable that the outer edge embossed portion be provided without any gaps by means of dot-like or lattice-like embossed components.

  Moreover, the flap embossing part which concerns on the modification 1 is provided in 2 rows spaced apart in the longitudinal direction. The flap embossed portion located at the rear is from the inner side in the width direction toward the outer side in the width direction toward the rear in the region ahead of the third maximum width position 65WM as the largest bulging portion located at the outermost side in the width direction in the flap portion. In the region rearward than the third maximum width position 65WM located on the outermost side in the width direction in the flap portion, it extends rearward from the outer side in the width direction toward the inner side in the width direction.
