Attachable-type disposable wearing article

An attachable-type disposable wearing article comprising:

• a crotch section containing a middle of front-back direction;
• a ventral section extending forward from the middle of the front-back direction;
• a dorsal section extending backward from the middle of the front-back direction;
• an absorber body contained in a region including the crotch section;
• an attaching part provided in each of opposed lateral portions of the dorsal section, and to be detachably attached to an exterior face of the ventral section;
• an end flap extending backward from a back edge of the absorber body;
• a stretchable sheet joined continuously both in the front-back direction and the width direction to a region including the end flap, wherein the stretchable sheet has a plurality of waist elastic members, a first sheet layer adjacent to a top side of the plurality of waist elastic members, and a second sheet layer adjacent to an underside of the plurality waist elastic members;
• and
• standup gather parts which stand up from a top face along shielding positions of bodily waste on opposed lateral sides in the width direction,
• wherein a region containing the plurality of waist elastic members is contracted in the width direction together with the plurality of waist elastic members, and has a waist stretchable region stretchable in the width direction,
• wherein each of the standup gather parts has a root portion fixed outward in the width direction of a shielding position, a main body portion extending from the root portion, a front laid-down portion and a back laid-down portion formed by fixing a front end portion and a back end portion, respectively, of the main body portion in a laid down state, a standup portion formed by unfixing the main body portion between the front laid-down portion and the back laid-down portion, and a gathering elastic member attached at least to a free edge area of the standup portion,
• wherein at least the free edge area of the standup portion is contracted in the front-back direction together with the gathering elastic member and is stretchable in the front-back direction, and
• wherein front edges of the back laid-down portions are backwardly away from the back edge of the absorber body,
• wherein the end flap has a first area located backward of the front edges of the back laid-down portions and a second area located between the front edges of the back laid-down portions and the back edge of the absorber body,
• wherein the waist stretchable region is provided over the first area and the second area at least between the opposed right and left back laid-down portions,
• wherein each of the first area and the second area contain the first sheet layer, the second sheet layer, and at least one of the plurality of waist elastic member,
• wherein the second area is raised along the back edge of the absorber body as a stand-up line such that the second area and a region adjacent to forward thereof are folded at a folding line extending coincident with the back edge of the absorber body as the standup portions of the standup gather parts contract, and
• wherein, with a portion of the waist stretchable region that is located in the second area contracted in the width direction, ridges extending from a boundary between the first area and the second area toward the back edge of the absorber body are formed repeatedly in the width direction in a top face of the second area.
