Each side wall part on a main body part includes a strip-like pouch part and an elastic member. The pouch part includes a first strip part extending in the longitudinal direction, and a second strip part disposed between the first strip part and the main body part and having both its edges along the longitudinal direction connecting to both edges of the first strip part. The elastic member is bonded to the first strip part linearly in the longitudinal direction. A standing part is formed in the pouch part by contraction of the elastic member. In each end part of the pouch part, a state where the pouch part overlaps with the main body part is maintained. Therefore, the height of the standing part changes gradually in a boundary part between the end part and the central part, which allows the standing part to fit against the wearer's skin.

Absorbent article

The present invention provides an absorbent article that allows full use of the absorption performance of an absorbent polymer without inhibiting the swelling of the absorbent polymer due to the absorption of excreted body fluids, and that can be biodegraded with efficiency when it is disposed after use by burial in the soil or the like. The absorbent article includes at least one inner bag-like member, an absorbent polymer, and an outer bag-like member. The inner bag-like member is formed into a thin and substantially sheet-like form of a sheet having biodegradability and fluid permeability, and includes multiple accommodation spaces that are detached from the outside and separated from one another. The absorbent polymer has biodegradability and a substantially granular or powder form and is contained in each of the accommodation spaces in the inner bag-like member so as to be freely movable within the accommodation spaces.

A diaper cover having a front part, a back part and an intermediate part located between the front part and the back part in a front-back direction, a right waist part and a left waist part extending from the back part in a width direction, and a right flap part and a left flap part extending from the front part in the width direction. The right flap part and/or the left flap part is provided with a hook member having a plurality of hooks. The hook member has a first region in which the hooks are oriented in one direction and a second region in which the hooks are oriented in another direction; and the first region and the second region are arranged such that a hypothetical straight line extending in the front-back direction in the right flap part or the left flap part crosses both the first region and the second region.

Diaper cover and disposable diaper

In an absorbent product (), a front pocket () and a rear pocket () are formed between a front absorbent core () and a rear absorbent core () and a back sheet (). A pair of side sheets () are located on both side portions of an absorbent sheet member () having an opening (). Both absorbent cores are raised so that they become spaced apart from the back sheet () by contraction of a third elastic member () bonded to an inner edge () of a bonded part () of each side sheet (). It is possible to keep the distance larger in a thickness direction between the absorbent sheet member () and the back sheet () in the vicinity of the opening () and fit a portion around the opening () of the absorbent sheet member () to a wearer.

Absorbent product

In an absorbent product in which an absorbent sheet member having an opening and a back sheet are overlapped, a rear pocket is formed between a rear absorbent core of the absorbent sheet member and the back sheet, and side pockets are formed on both sides of the opening. By contracting elastic members bonded to a core covering sheet on the both sides of the opening, the core covering sheet of the absorbent sheet member and the back sheet largely stand up in each side pocket, and the rear absorbent core is raised upward. Thus, it is possible to keep the distance large in a thickness direction between the absorbent sheet member and the back sheet in the vicinity of the opening and to fit a portion around the opening of the absorbent sheet member to a wearer.
