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

Patent number: 9012716Abstract: A technique for incorporating odor control agent particles into an absorbent article is provided. More specifically, the odor control particles are “homogenously” distributed (e.g., in a substantially uniform manner) within an airformed fiber matrix of an absorbent core of an absorbent article. An absorbent core containing such a homogeneously distributed odor control particles may possess a greater surface area for contacting malodorous compounds, thereby increasing the likelihood of odor reduction.Type: GrantFiled: June 29, 2010Date of Patent: April 21, 2015Assignee: Kimberly-Clark Worldwide, Inc.Inventors: David Arthur Fell, Megan Lan, William Anthony Georger, Kelly Davis Arehart, Bao Trong Do, Stephanie Michelle Martin
