Publication number: 20030009142Abstract: A multi-layer feminine hygienic pad comprising a laminate of two or more composite absorption sheets in which an upper composite absorption sheet comprising an upper backing sheet laminated to a back side thereof is laid on top of a lower composite absorption sheet comprising a lower backing sheet laminated to a back side thereof such that the back side of the upper composite absorption sheet is placed downward and peripheral parts of the lower backing sheet and the upper backing sheet are temporarily attached together by a high pressure pressing and, a back side of a lowest backing sheet of a lowest composite absorption sheet is attachable to underwear. The feminine hygienic pad does not require a woman to carry along a number of pads as replacements. The previous troublesome handling to fix the pad to a desired position of underwear is reduced to once with a plurality of composite absorption sheets.Type: ApplicationFiled: August 14, 2002Publication date: January 9, 2003Applicant: Mica NUKINAInventors: Mica Nukina, Mitsuru Uchiyama, Mitsuko Uchiyama, Mitsuo Ohtani, Atsushi Uchiyama
