Patent number: 9035125Abstract: The present invention aims to provide a disposable wearing article improved so that front and rear waist regions may assure desired fitness without adversely affecting an absorption capacity of a bodily fluid-absorbent core assembly. At least one of front and rear waist regions includes an inner sheet lying on a skin-facing side and having stretch properties and an outer sheet lying on a non-skin-facing side and having a low elastic contractile force. In a section of this one waist region occupied by a liquid-absorbent core assembly including a bodily fluid-absorbent core, the inner sheet is partially cut to define a perforated region. Adhesive used to bond the liquid-absorbent core assembly to the inner sheet and adhesive used to bond the inner sheet to the outer sheet are put in contact with and joined to each other through openings developed by partially cutting the inner sheet.Type: GrantFiled: December 27, 2010Date of Patent: May 19, 2015Assignee: UNICHARM CORPORATIONInventors: Toshifumi Otsubo, Tatsuya Hashimoto, Mariko Takeuchi

Publication number: 20150112291Abstract: A simple disposable absorbent article including a chassis and an absorbent assembly. The chassis includes a water-impermeable sheet folded laterally inward at both of its side edges to form opposing side flaps. Each side flap is attached to the interior surface of the chassis adjacent to its end edges. Each side flap has a longitudinally extending elastic gathering member attached adjacent to its proximal edge. The absorbent assembly is smaller in width and in length than the chassis. The side edges and end edges of the absorbent assembly may be disposed proximally relative to the respective side edges and end edges of the chassis. The absorbent assembly includes an absorbent core that may contain superabsorbent particles, which may be contained inside pockets. The chassis may be extensible. The absorbent assembly may be in a cruciform pattern to the chassis to allow portions of the chassis to extend laterally.Type: ApplicationFiled: January 6, 2015Publication date: April 23, 2015Inventors: Gary Dean LAVON, Kevin Michael SMITH, Michael Patrick HAYDEN
