  As shown in FIG. 10, when the absorbent article 1 is worn, each of the first leg gathers 43 and the second leg gathers 44 extends to the outside of the garment 201 and extends downward along the wearer's thigh. It extends to. Moreover, while the 1st leg gathers 43 extend below along a wearer's thigh, the 1st leak-proof wall 21 stands up toward a wearer's skin, and it becomes difficult to leak a bodily fluid. Similarly, the second leg gather 44 extends downward along the inside of the wearer, and the second leak-proof wall 27 stands up toward the wearer's skin, making it difficult for body fluid to leak.

  In 1st Embodiment, although the absorbent article 1 had each of the 1st flap part 5 and the 2nd flap part 9 in the front area | region FR, center area | region CR, and back area | region BR, the absorptivity of this indication The article only needs to have a pair of flap portions in a part of the central region, and preferably has the entire central region. This is from the viewpoint of the effect of the present disclosure. The absorbent article of the present disclosure may further include a pair of flap portions, for example, in a front region (that is, a pair of front flap portions), and further include a rear region (that is, a pair of rear flap portions). Can do. The absorbent article of the present disclosure can have, for example, a pair of flap portions in a front region (ie, a pair of front flap portions) and a central region (ie, a pair of central flap portions), and a central region (ie, a pair of front flap portions). A pair of central flap portions) and a rear region (that is, a pair of rear flap portions).

  In each of the first region and the second region of the absorbent article of the present disclosure, the central flap portion has a length in the width direction of the absorbent article between the outer edge of the central flap portion and the side edge of the absorbent core. A portion longer than the width of the absorbent article between the side edge of the absorbent core and the longitudinal center line, preferably 1.2 times or more, more preferably 1.4 times or more, and More preferably, it includes a portion that is 1.6 times longer. By doing so, the length of the pair of leg gathers constituted by the pair of central flap portions extending to the outside of the clothing is increased, and body fluid is less likely to leak. In addition, it is preferable to satisfy | fill the relationship of the above-mentioned length on the same straight line extended in the width direction of an absorbent article.

  Moreover, it is preferable that each of a pair of center flap part does not have the fixing | fixed part for fixing to clothes. This is because, in the wearing state of the absorbent article, the pair of central flap portions constitute a pair of leg gathers and extend downward along the wearer's thigh.

  When the absorbent article of the present disclosure includes a front flap portion (a pair of front flap portions) in each of the first region and the second region, the front flap portion in each of the first region and the second region. The width of the absorbent article between the outer edge of the front flap portion and the side edge of the absorbent core is the width of the absorbent article between the side edge of the absorbent core and the longitudinal center line. It includes a portion longer than the length in the direction, preferably 1.1 times or more, more preferably 1.2 times or more, and even more preferably 1.3 times or more. By doing so, it becomes easy for a wearer to hold | grip a front flap part, and it becomes easy to adjust the position of an absorbent article. In addition, it is preferable to satisfy | fill the relationship of the above-mentioned length on the same straight line extended in the width direction of an absorbent article.

  Moreover, in the above-mentioned case, it is preferable that each of a pair of front flap part does not have a fixing part for fixing to clothes. This is because, when the absorbent article is worn, the wearer grips the pair of front flap portions, and in the wearing state, the pair of front flap portions may extend to the outside of the clothing. Furthermore, it is preferable that each of a pair of front flap parts has a part extended in the width direction outer side of an absorbent article rather than a pair of center flap part. This is because when the absorbent article is worn, the pair of central flap portions can be easily adjusted to a predetermined position on the outer side in the width direction of the absorbent article.

  In the case where the absorbent article of the present disclosure includes a rear flap portion (a pair of rear flap portions) in each of the first region and the second region, the rear flap portion in each of the first region and the second region. The width in the width direction of the absorbent article between the outer edge of the rear flap portion and the side edge of the absorbent core is the width of the absorbent article between the side edge of the absorbent core and the longitudinal center line. It includes a portion longer than the length in the direction, preferably 1.1 times or more, more preferably 1.2 times or more, and even more preferably 1.3 times or more. By doing so, it becomes easy to act so that a pair of back flap parts may prevent a pair of leg gathers from entering the inside of clothes. In addition, it is preferable to satisfy | fill the relationship of the above-mentioned length on the same straight line extended in the width direction of an absorbent article.

  Moreover, in the above-mentioned case, it is preferable that each of a pair of back flap part has a fixing | fixed part for fixing to clothes. This is from the viewpoint of suppressing the pair of leg gathers from entering the inside of the clothes. Furthermore, it is preferable that each of a pair of back flap parts has a part extended in the width direction outer side of an absorbent article rather than a pair of center flap part. This is because the pair of leg gathers hardly enters the inside of the clothes. Moreover, in that case, it is more preferable that each of the pair of rear flap portions has the fixing portion at a portion extending outward in the width direction of the absorbent article, rather than the pair of central flap portions. This is because the pair of leg gathers is less likely to enter the inside of the clothes.

  In the absorbent article 1 according to the first embodiment, the first flap portion 5 and the second flap portion 9 were each provided with the first elastic member 33 and the second elastic member 35 from the central region CR to the rear region BR. However, in the absorbent article according to the present disclosure, the pair of flap portions may include an elastic member in at least a part of the central region. This is because each of the pair of flap portions forms leg gathers (a pair of leg gathers) together with the elastic member in at least a part of the central region, thereby making it difficult for body fluid to leak.

  Moreover, the elastic member (a pair of elastic member) which comprises each of a pair of leg gathers has a front-end part and a rear-end part of a longitudinal direction, and a front-end part is from a back-end part. Is preferably close to the center line in the width direction. When the absorbent article is worn, the pair of front flap portions are attached to the elastic member and are difficult to enter the inner side in the width direction (longitudinal center line side) of the absorbent article. This is because it is easy to grip and adjust the position of the absorbent article.

When the absorbent article of the present disclosure is provided with a pair of flap portions in the rear region (when provided with a pair of rear flap portions), the pair of elastic members constituting the pair of leg gathers is up to the rear region, that is, You may extend to a pair of back flap parts. This is because the pair of rear flap portions is not easily affected by the elastic members constituting the leg gathers.
Moreover, when the absorbent article of this indication is equipped with a pair of flap part in a front area (when provided with a pair of front flap part), the elastic member which comprises a leg gather is a front area, ie, a pair of pair. It is preferable not to extend to the front flap part. This is because the pair of front flap portions is easily influenced by the elastic members constituting the leg gathers, and the pair of front flap portions easily enters the inside of the clothes.

  The absorbent article 1 according to the first embodiment has the first leakage prevention wall 21 and the second leakage prevention wall 27 in the first region FI and the second region SE. Each of the first region and the second region may not have a leak-proof wall. This is because the effect of the present disclosure is achieved by providing the absorbent article of the present disclosure with a pair of leg gathers in a worn state.

When the absorbent article of this indication is provided with a pair of leak-proof walls, it is preferred that those fixed ends exist on a pair of flap parts. In the wearing state of the absorbent article, as the pair of central flap portions (the pair of leg gathers) extend downward along the wearer's thigh, the pair of leak-proof walls easily stand toward the wearer's skin. Because.
Moreover, when the absorbent article of this indication is equipped with a pair of leak-proof walls, it is preferable that those free ends exist on an absorptive main-body part. This is because, as the pair of central flap portions (the pair of leg gathers) extend downward along the wearer's thigh, the pair of leak-proof walls easily stand up toward the wearer's skin and inward.

  In the absorbent article according to the present disclosure, in each of the first region and the second region, the elastic member constituting the leg gather includes an intersection of the width direction center line and the side edge of the absorbent core, and an outer edge of the front flap portion. It is preferable that the imaginary line segment connecting the front point located at the center in the longitudinal direction in the outermost part in the width direction is arranged so as not to overlap in the thickness direction of the absorbent article. This is because, in the wearing state, the pair of leg gathers are attracted to the clothes and are not easily drawn into the inside of the clothes, the position of the absorbent article is difficult to shift, and the pair of leg gathers easily exhibits its function.

When the absorbent article of the present disclosure includes a pair of flap portions in the front region (when the pair of front flap portions includes a pair of front flap portions), the absorbent main body portion includes the first front flap as in the first embodiment. A first front point located in the center in the longitudinal direction in the outermost portion in the width direction of the outer edge of the outer portion, and a center in the longitudinal direction in the outermost portion in the width direction of the outer edge of the second front flap portion It is preferable that a fixing portion is provided in front of the imaginary line passing through the second front point that is positioned in order to fix to the clothes. When the wearer wears the absorbent article, it becomes easy to adjust the position of the absorbent article by gripping the pair of front flaps, and the front region of the absorbent article in the worn state is the inguinal part of the wearer This is because the absorbent article continues to fit and the absorbent article becomes difficult to twist.
In the absorbent article according to one of the embodiments of the present disclosure, the absorbent main body portion has a fixed portion in front of the above-described imaginary line.

  When the absorbent article of the present disclosure includes a pair of flap portions in the front region (when including a pair of front flap portions), the widthwise center of the absorbent article in each of the first region and the second region. The front imaginary line segment connecting the intersection of the line and the side edge of the absorbent core and the front point located at the center in the longitudinal direction in the outermost portion in the width direction of the outer edge of the front flap portion is the flap. It is preferable that it does not overlap in the thickness direction of the said absorbent article except the outer edge of a part and a front point. By doing so, as mentioned above, it is difficult for the wearer to feel discomfort in the wearing state of the absorbent article.

  When the absorbent article of the present disclosure includes a pair of flap portions in the rear region (when including a pair of rear flap portions), the rear flap portion is attached to the clothing in each of the first region and the second region. It has a fixing part for fixing, and the longitudinal direction in the outermost part in the width direction of the outer edge of the rear flap part and the intersection where the widthwise center line of the absorbent article and the side edge of the absorbent core intersect It is preferable that the rear imaginary line segment connecting the rear point located at the center of the outer periphery of the flap portion does not overlap with the thickness direction of the absorbent article except for the rear point. This is because the wearer is less likely to feel discomfort when the absorbent article is worn as described above.

  In addition, the above-mentioned front point (1st front point, 2nd front point) is when the outermost part of the width direction of the outer edge of a front flap part does not have fixed length, ie, a point. Means the point, and when it has a certain length, it means a point located in the center in the longitudinal direction. Similarly, the above-described rear points (first rear point, second rear point) are when the outermost portion in the width direction of the outer edge of the rear flap portion does not have a certain length, that is, when it is a point. Means the point, and when it has a certain length, means a point located at the center in the longitudinal direction.

  The absorbent article of the present disclosure can be folded, for example, folded into two, three, four, etc., individually packaged, and sold as an individually packaged absorbent article. Since the absorbent article of the present disclosure is folded in two along the widthwise center line, a gap is easily formed between the wearer and the wearer along the widthwise center line in the wearing state. However, it becomes difficult to directly touch the body fluid absorbed by the absorbent article.

  In the absorbent article of the present disclosure, the first elastic member and the second elastic member are not particularly limited, and are, for example, linear elastic members, for example, thread rubber, flat rubber, planar linear members, for example, expansion and contraction. Examples thereof include an elastic sheet (for example, a stretchable nonwoven fabric). Each of the first elastic member and the second elastic member is a planar linear member, so that each of the first leg gather and the second leg gather can fit in the wearer's thigh on the surface, Each of the first leg gather and the second leg gather is excellent in the touch.
