Patent number: 9452092Abstract: 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.Type: GrantFiled: May 23, 2012Date of Patent: September 27, 2016Assignee: LIVEDO CORPORATIONInventors: Hirofumi Miyake, Miyuki Okawa, Akiko Tatsukawa

Publication number: 20130144243Abstract: In an absorbent product, a front pocket, a pair of side pockets and a rear pocket are formed between a back sheet member, and a front absorbent core, a pair of side absorbent cores and a rear absorbent core, and excrement which has passed through an opening is collected therein. In the absorbent product, the side absorbent cores are bonded on inner surfaces of standing gather parts. Thus, since the standing gather parts stand up, the side absorbent cores become far away from the back sheet member. Side wall parts of the side pockets have structure where the side absorbent cores are bonded on the inner surfaces of side sheets and outer covering sheet. Thus, it is possible to increase stiffness of the side wall parts of the side pockets, to thereby suppress deformation of the side wall parts due to a weight of excrement collected in the side pockets.Type: ApplicationFiled: April 13, 2011Publication date: June 6, 2013Applicant: LIVEDO CORPORATIONInventors: Hirofumi Miyake, Akiko Tatsukawa

Publication number: 20120197228Abstract: A urine receiving pad 1 has a substantially rectangular bag body 10. The bag body 10 has a side edge portion 16 extending in a lengthwise direction thereof, and a top edge portion 15 connected to the side edge portion 16 and extending in a widthwise direction perpendicular to the lengthwise direction. In the side edge portion 16, an opening 10P opening in the widthwise direction is provided at the side edge portion 16a which is continuous with the top edge portion 15. Since a male genitalia P is inserted through the opening 10P along the widthwise direction, a bottom portion 10c tends to be positioned below the male genitalia P. This can prevent a portion near the bottom portion 10c from being largely folded even when a diaper, underwear, or the like, is worn. Thus, an overflow of urine from the opening 10P can be effectively suppressed.Type: ApplicationFiled: November 22, 2010Publication date: August 2, 2012Inventors: Hirofumi Miyake, Akiko Tatsukawa

Publication number: 20120046633Abstract: The absorbent product for male comprises a bag-like main body part having an opening at an upper end, and two hydrophilic internal sheets which are band-like members located in the main body part. An upper end part of each internal sheet is fixed on an upper part of the main body part and the other portions are not bonded to the main body part. Internal sheet elastic members each extending in an up-down direction are bonded to each internal sheet, and by contraction of these members, gathers are formed in the internal sheet. In the absorbent product, since urine moves in the internal sheet comparatively slowly through the gathers formed in the internal sheet, a time required for the urine to reach the bottom part of the bag part can be increased. As the result, a large area of absorbent part can be utilized to absorb the urine effectively.Type: ApplicationFiled: May 11, 2010Publication date: February 23, 2012Inventors: Miyuki Okawa, Akiko Tatsukawa, Hirofumi Miyake
