Publication number: 20130131623Abstract: An incontinence liner is provided with a liquid permeable skin contact side sheet, a liquid impermeable non-skin contact side sheet, and an absorptive body arranged between the skin contact side sheet and non-skin contact side sheet and including an absorptive material. The absorptive material includes 30 to 70 mass % of a high absorption polymer. The absorptive body includes an absorbing part positioned at a urinating position of a wearer when worn, a diffusing part extending around the absorbing part up to a peripheral edge of the absorptive body, and diffusion-suppressing parts scattered inside the diffusing part. An average absorptive material density of the diffusing part is higher than the absorbing part and the diffusion-suppressing parts. The absorbing part projects toward the skin contact side sheet more than the other parts of the absorptive body, while the diffusion-suppressing parts project toward the skin contact side sheet more than the diffusing part.Type: ApplicationFiled: August 25, 2011Publication date: May 23, 2013Applicant: UNICHARM CORPORATIONInventor: Yusuke Kawakami
