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

The absorbent article 1 is formed with a main body embossed portion 80 that compresses the surface sheet 10 and the main body absorbent body 30 in the thickness direction, and a flap embossed portion 70 that presses the surface sheet and the flap absorbent body in the thickness direction. Further, the main body embossing portion 80 and the flap embossing portion 70 press at least the surface sheet 10 and the main body absorbent body in the thickness direction T, or at least the surface sheet 10 and the flap absorbent body are pressed in the thickness direction T. Yes, various structures can be employed. For example, it may be formed by press working, embossing, or the like, and its shape may be a lattice mesh shape, a honeycomb shape, or the like.

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

The flap portion 60 has a portion that is located closer to the first neck portion 61 a first flap portion 63 at a position on the front side; a second flap portion 64 located further rearward than the first neck portion 61 and further forward than the second neck portion 62; and a second neck portion 62 The third flap portion 65 at the rear position.

The first flap portion 63 is a region from the rear inner end portion 43RI located at the rear of the inner end portion in the width direction of the flap portion 43 to the first neck portion 61, and is rearward from the rear inner end portion 43RI. , extending outward in the width direction. The first maximum width position (outer end portion) 63WM located at the outermost side in the width direction of the first flap portion 63 is closer to the outer side in the width direction than the first neck portion 61. The first maximum width position 63 WM is located further rearward than the center of the first flap portion 63 in the front-rear direction.

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

The third flap portion 65 is a region from the second neck portion of the rear end portion of the second flap portion 64 to the rear end portion of the flap portion, and is rearward from the second neck portion 62. , extending outward in the width direction. The third maximum width position (outer end portion) 65WM located at the outermost side in the width direction of the third flap portion 65 is closer to the outer side in the width direction than the second neck portion 62. The 3rd maximum width position 65WM is located on the 3rd flap The position of the portion 65 in the front-rear direction is further rearward.

Next, the details of the flap embossing portion will be described. The flap embossing portion has a first flap embossing portion 71 extending rearward from the vicinity of the rear inner end portion 43RI of the flap portion 43, and is branched from the first flap embossed portion 71 and directed toward the first necking a second flap embossing portion 72 extending from the portion 61; a third flap embossing portion 73 extending from the first flap embossed portion 71 and extending toward the second necking portion 62; and; from the first flap The embossed portions 71 are branched and are oriented toward the fourth flap embossed portion 74 that extends in the vicinity of the third maximum width position 65WM on the outer side in the width direction of the third flap portion 65. The flap embossing 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 provided, the body fluid can be absorbed even in the flap portion, and occurrence of back leakage, side leakage, and the like can be suppressed. For example, in a sleeping posture or the like, there is a possibility that menstrual blood leaks from the gap between the buttocks and the absorbent article. However, since the flap absorber 35 is provided in the flap portion 60, it is possible to suppress the occurrence of the back leak.

Further, since the flap absorbing body 35 is provided in the flap portion 60, the rigidity of the flap portion is increased, and the flap portion is less likely to be deformed. However, the second flap embossed portion 72, the third flap embossed portion 73, and the fourth flap embossed portion 74 are configured to extend outward in the width direction from the inner side in the width direction toward the rear portion. The flap embossing portion is applied along the direction of the force, and therefore, the flap embossing portion becomes the folding starting point, and the flap portion is naturally folded. Therefore, the flap portion 60 can be naturally fitted regardless of the body or the undergarment. Therefore, it is not easy to produce disorder in the flaps. Wrinkles can produce distortion without discomfort and provide a simple installation.

The flap embossing portion is constituted by a plurality of embossing portions pressed in the thickness direction. Specifically, the second flap embossing portion 72, the third flap embossed portion 73, and the fourth flap embossed portion 74 are each formed of an aggregate of a plurality of dot embossed portions. The dot embossing constituents are arranged in a line shape and are not connected to each other. According to the assembly of the plurality of dot-like embossed portions, it is possible to suppress the flap portion from being excessively hardened by the embossed portion, compared to the embossed portion having the linear continuous shape. Therefore, the flap portion is easily deformed softly along the body curve, and the flap portion can be more fitted to the body.

Further, the first flap embossing portion extends in the longitudinal direction and is provided to be connected from the rear end portion of the flap portion 43 to the rear end portion of the flap portion. Therefore, when the liquid is diffused from the center in the width direction of the absorbent article toward the outside in the width direction, the liquid is sucked into the first flap embossing portion, and the body fluid can be prevented from diffusing outward in the width direction from the first flap embossed portion.

Further, the flap embossing portions are arranged in a plurality of overlapping manners in the width direction. Specifically, the first flap embossing portion and the second flap embossing portion, the third flap embossing portion, and the fourth flap embossing portion overlap in the width direction. The second flap embossing portion overlaps the first flap embossing portion and the third flap embossed portion in the width direction. The third flap embossing portion overlaps the first flap embossing portion, the second flap embossing portion, and the fourth flap embossing portion in the width direction.

Since the flap embossed portions overlap in the width direction, the body fluid flows from the center in the width direction of the absorbent article toward the outside in the width direction. In the case of the first flap embossing portion, the second flap embossing portion 72, the third flap embossing portion 73, and the fourth flap embossing portion 74, the body fluid is sucked in a double or triple manner to prevent body fluids. Reach the outer edge of the absorbent article.

Further, since the first flap embossed portion 71 extends in the longitudinal direction from the vicinity of the rear end portion of the flap portion 43, in the vicinity of the flap portion, the wearer's foot is directed outward from the width direction. When pressed inward in the width direction, it becomes a deformation base point. Since a plurality of flap embossing portions are provided from the first flap embossed portion 71, even if a large deformation occurs in the vicinity of the flap portion 43, a plurality of flap embossing portions can be used as a base point. Deformation occurs, and the entire flap portion can be softly deformed.

Further, the first flap embossed portion 71 is disposed further rearward than the rear end portion of the flap portion 43, and is separated from the rear end portion of the flap portion 43, but is not limited to this configuration. The first flap embossed portion 71 also extends rearward from the rear end portion of the flap portion 43, for example.

An outer edge embossing portion 85 is provided on the outer edge of both end portions in the width direction of the absorbent article. The outer edge embossed portion 85 is composed of a plurality of embossed portions pressed in the thickness direction. Specifically, the outer rim embossed portion 85 is composed of an aggregate of a plurality of dot embossed constituent portions. The dot embossing constituents are arranged in a line shape and are not connected to each other.

The dot-shaped embossed portion constituting the outer rim embossed portion is configured to have a shape or a depth different from that of the dot embossed portion constituting the flap embossing portion. Specifically, the area of the embossed portion constituting the flap embossing portion is larger than the area of the dot embossed portion constituting the outer rim embossed portion. Or, the depth of the dot-shaped embossing portion constituting the flap embossing portion is smaller than the dot embossing constituting the outer edge embossing portion The depth of the components is deep.

Since the flap embossing portions are disposed substantially in contact with each other at the inner side of the outer edge embossed portion, it is possible to prevent the body fluid from flowing to the outer edge of the absorbent article. Further, the user can clearly recognize the second flap embossed portion 72, the third flap embossed portion 73, and the fourth flap embossed portion 74, and can recognize that the flap embossed portion of the inhalable body fluid exists in the comparison. The outer edge of the absorbent article is further inside, and a feeling of relief that is less likely to cause side leakage can be obtained.

Further, the embossed constituent portion constituting the flap embossed portion is larger in area or deeper than the embossed portion constituting the outer rim embossed portion, and is easily conspicuous. Therefore, the flap embossing portion can be made more conspicuous. It is easy for the user to find a flap embossing portion for preventing the side leakage from being present on the inner side of the outer edge of the absorbent article, and a higher feeling of security can be obtained.

Further, it is desirable that the shape of the embossed portion constituting the flap embossed portion is different from the shape of the embossed portion constituting the outer rim embossed portion. Further, the shape of the embossed portion is different from that of a shape having a shape different from a circle or a triangle, and a similar shape having the same shape but different sizes. By making the shape of the embossed portion constituting the flap embossed portion different from the shape of the embossed portion constituting the outer rim embossed portion, it is possible to recognize that the flap embossed portion of the inhalable body fluid is present in the absorbent article. The outer edge is more inside, and it is possible to obtain a sense of relief that is less prone to side leakage.

The outer rim embossed portion and the flap embossed portion are disposed at intervals. For example, when the outer edge embossing portion is connected to the flap embossing portion, the body fluid sucked by the flap embossing portion is transmitted to the outer edge embossing portion. However, since the outer rim embossing portion is separated from the flap embossing portion, the inhalation by the flap embossing portion can be suppressed. The body fluid is transmitted to the outer edge embossing portion to suppress body fluid leakage.

Next, a part of the method for producing the absorbent article 1 according to the first embodiment will be described. Furthermore, as for the method not described, an existing method can also be used. In the method for producing an absorbent article, as a first step, a surface sheet forming process is performed. Next, as a second step, a surface sheet bonding process is performed. Specifically, the body surface sheet 11 and the flap surface sheet 12 are followed by, for example, heat fusion.

As a third step, an absorber forming process is performed. Specifically, the main absorbent body and the flap absorbent body are molded by molding a pulp which is a material of the absorbent body by a forming roll. Further, the order of the surface sheet manufacturing process in the first step and the second step and the absorber forming process in the third step may be reversed.

In the fourth step, the bonding process is performed. Specifically, a joining process of joining the main body absorbent body and the flap absorbent body formed in the third step to the surface sheet and the side sheet joined in the second step is performed.

In the fifth step, the pressing process is carried out. Specifically, the main body absorber and the surface sheet 10 are compressed in the thickness direction to form the main body embossed portion 80, and the flap surface sheet 12 and the flap absorbent body 35 are compressed in the thickness direction to form the flap embossed portion 70. In the sixth step, a back sheet bonding process is performed. Specifically, the absorber and the surface sheet on which the embossed portion is formed are joined to the back sheet. After the foregoing steps, there are further provided: a process of forming the outer edge embossing portion 85; and a process of applying an adhesive. The absorbent article of the present embodiment can be produced by the above-described process.

Next, the absorbent article 1A of the first modification will be described. Fig. 5 is a plan view seen from the surface side of a part of the absorbent article 1A of the first modification. In the absorbent article shown in Fig. 5, the embossed portion constituting the embossed flap portion has a pattern embossing portion 91 for displaying a pattern shape, and an image embossing portion 92 for displaying an image shape.

The pattern embossing portion 91 is an embossed portion that displays a pattern shape. Furthermore, the graphical shape refers to the concept of a polygon including points, lines, circles, triangles, and quadrangles. The image embossing portion 92 is an embossed portion that displays an image shape. Furthermore, the image shape refers to a concept including various patterns, portraits, and the like such as a star pattern, a heart pattern, a leaf pattern, and a flower pattern.

By having the image embossing portion 92, the appearance can be improved. Moreover, the absorbent article 1A can be decoratively decorated to alleviate the depression mood of the user during the physiological period. Further, the image embossing portion 92 is more conspicuous than the linear embossed portion, and the user can recognize that the embossed portion for absorbing the body fluid exists at a position further inside the outer edge embossed portion 85. Therefore, the user can get a sense of peace of mind to the side leakage.

Further, the area of the image embossing portion 92 is larger than the area of the pattern embossing portion 91. Therefore, the image embossing portion 92 is more conspicuous than the pattern embossing portion 91 and can serve as a mark. For example, in the case where the menstrual blood spreads to the flap portion 60, the flap embossed portion inhales the menstrual blood and oozes out. At this time, since the menstrual blood oozes to the image embossing portion having a large area, the user can recognize the image embossing portion that has permeated the blood, and it is easy to determine the replacement period.

The pattern embossing portion 91 is arranged on a predetermined line, The embossed component is placed at a position offset from the line. Furthermore, the line includes not only a straight line but also a curved line. By arranging the pattern embossing portion 91 on a predetermined line, the pattern embossing portion 91 can be closely arranged, and the body embossing portion can be sucked by the pattern embossing portion, thereby preventing side leakage. Further, by arranging the image embossing portion 92 at a position shifted from the line where the pattern embossing portion 91 is disposed, the image embossing portion 92 can be made conspicuous, and the side leakage preventing function can be ensured. Can improve the aesthetics.

The width dimension W92 of the image embossing portion 92 orthogonal to the predetermined line is larger than the width W91 of the predetermined line. Since the width dimension of the image embossing portion 92 orthogonal to the predetermined line is larger than the width of the line on which the pattern embossing portion 91 is disposed, the image embossing portion 92 can be conspicuous and the appearance can be improved. . Further, since the area of the image embossing portion 92 is large, even when the body fluid permeates into the entire pattern embossing portion 91, the body fluid does not permeate into the entire image embossing portion 92. The replacement period is grasped by the image embossing unit 92.
