摘要： An absorbent article which can effectively widen absorbing area of excretion liquid at a center portion of the absorbent article, is provided. Divided absorbent elements are formed dividingly on both of a center line. The divided absorbent elements are fixed on a back sheet at positions of compressed portions, and inner side end portions of the divided absorbent elements are taken as free ends. Upon use of a sanitary napkin, by bending the sanitary napkin in response to exertion of compressing force F from femoral parts, the divided absorbent elements are raised so that menstrual blood can be absorbed not only through inner surfaces but also through outer surfaces. Therefore, absorbing area can be greater than that of the conventional sanitary napkin, and side leakage can be successfully prevented.

摘要： An absorbent article having leakage preventing walls that longitudinally exert an elastic contractive force to bend a main body. Each leakage preventing wall is provided, between front and rear ends, with a constraint portion so as to locally constrain an allowable rising height of the leakage preventing wall. Thus, the leakage preventing wall takes a shape that can easily conform to a curved surface of the wearer's body.

摘要： A sanitary napkin that is provided with large rear flaps to effectively prevent liquid from leaking obliquely rearward. The rear flaps are disposed rearward of fold-back flaps to be wrapped around a crotch part of an undergarment. The rear flap is of a shape spreading rearwardly from a starting point. With a pressure from the thighs acting forward of the starting point, leakage preventing walls forward of the starting point can be maintained in a rising state during wear. On the other hand, the leakage preventing walls rearward of the starting point may possibly fall outward. However, even if the leakage preventing walls fall outward rearward of the starting point, they will never project out of the rear flaps. Accordingly, they hardly leave a stain on an undergarment.

摘要： An absorbent article worn in the groin area, in which, when a compressive force is received from a lateral direction, a main absorbent region can oppose an excretion area of a wearer's body without twists or wrinkles occurring, and when the compressive force is relaxed, the article easily recovers to its original shape. An absorbent body provided in the absorbent article has a main absorbent region, reinforcing regions, and buffer regions. The bending stiffness of the reinforcing regions and the main absorbent region is larger than that of the buffer regions. When compressive force is received from a wearer's thigh areas in the lateral direction, the reinforcing regions that are positioned to the left and right deform in a curved shape, and the buffer regions that are to the left and right are compressed. The main absorbent region does not easily deform, and maintains a tight fit.

摘要： Disclosed is an absorbent article including: a liquid-permeable topsheet; a backsheet; an absorbent storage layer between the topsheet and the backsheet; and a cushion layer between the topsheet and the absorbent storage layer. When a tensile force of 490 mN per 25 mm width is applied to the topsheet in a transverse direction crossing the cushion layer, an extension is at least 30%. When the absorbent article is pressed from above in a region having the cushion layer, an initial thickness T0 of the pressed region of the absorbent article for a pressure of 49 Pa is at least 10 mm, a compressive hardness (LC value) is 0.5 to 0.65, and a compressive recovery (RC value) is at least 35%.

摘要： Disclosed is a sanitary napkin including: a backsheet; a liquid-permeable topsheet; and an absorbent layer which is capable of absorbing a liquid and disposed between the backsheet and the topsheet. At least a part of a region in which the absorbent layer is provided is adapted to receive a liquid. The liquid-receiving region includes a raised region in which a hydrophilic material layer is provided. The raised region is continuously elongated in a longitudinal direction of the sanitary napkin. The raised region includes a front region for coming into contact with a vaginal opening of a wearer and a rear region for coming into contact with buttocks of the wearer. When the front region and the rear region are respectively depressed with a given pressure, an amount of the depression of the rear region is larger than an amount of the depression of the front region.

As a result, the main absorbent region does not easily deform, and the main absorbent region can have a tight fit to the excretion area of the wearer's body in a non-deformed state.

摘要： A sanitary napkin in which diffusing liquid hardly reaches a rear end edge is adapted to make a liquid absorbent layer less deformable in a rear region so that it can easily be kept in close contact with the wearer's buttocks. The sanitary napkin has an elongated main absorbent region surrounded by compressed grooves that are formed in a skin-side surface. Since a rear end of the main absorbent region is far away from a rear end edge of the napkin to provide a relatively large rear region, worries about rearward leakage may be relieved. Furthermore, since auxiliary longitudinal grooves are provided in the rear region, a liquid absorbent layer may hardly be twisted.
