Publication number: 20020095132Abstract: Absorbent articles having improved sustained fit on the body, improved appearance through the period of use, and improved comfort for the wearer. The absorbent article has a containment assembly, a waist feature and a diagonal support member feature disposed so as to lie in the diagonal support zone of the wearer's body when the article is worn. The diagonal support member is designed to support the article from the small of the back, over the hip, and to the lower abdomen. The diagonal support member is distinct from the waist feature, which is designed to provide only enough circumferential tension to hold itself in position on the body. The absorbent article has a garment-like high-waisted appearance, gentle tension around the waist to avoid discomfort and/or pressure marking, good leakage protection, good sustained fit, and easy application and removal.Type: ApplicationFiled: January 18, 2001Publication date: July 18, 2002Inventors: Gregory Ashton, Frederick Michael Langdon

Publication number: 20010053903Abstract: A disposable diaper has a pair of rear wings and the wings partially extend outward in a circumferential direction to form fastener sections. The wings are formed on inner surfaces thereof with a plurality of fine depressions. The number of these depressions per unit area on the inner surfaces of the respective rear wings is less in regions adapted to be engaged with the male members of the respective fastener sections as these fastener sections are folded back onto the inner surfaces of the respective rear wings than in the remaining region.Type: ApplicationFiled: June 13, 2001Publication date: December 20, 2001Inventors: Yoshikazu Shingu, Hirotomo Mukai

Patent number: 6306123Abstract: An absorbent article, such as a sanitary napkin, is disclosed which has a stabilizing element having a length and a width sufficient to conform to the longitudinal dimensions of a wearer's labia majora. The stabilizing element provides the article with enhanced resistance to bunching and inward collapse due to lateral compressive forces imparted by a user's thighs. The stabilizing element is resistant to wet collapse so that a central absorbent portion of the article maintains contact with the perineal area of the user.Type: GrantFiled: July 22, 1998Date of Patent: October 23, 2001Inventors: Catherine E.

Patent number: 6307120Abstract: An adult brief garment for use in controlling incontinence is provided. The brief has a chassis which includes a front portion, back portion and an interposed crotch portion. The chassis consists of a fluid-impervious, cloth-like laminate along the central region of the chassis and hydrophobic, cloth-like, nonwoven side panels at each side of the central region. An liquid absorbent core is positioned over the central region. Plural fastening tapes are applied to the side panels at the back portion of the chassis. The front portion of the chassis includes soft, flexible landing zones for releasable receipt of the tapes to hold the brief in place. Each landing zone takes up a substantial portion of its associated side panel and contiguous portions of the central region of the chassis and each includes a myriad of small (e.g., micro-sized) apertures or holes therein for breathability, e.g., to allow moisture vapor to pass therethrough.Type: GrantFiled: June 9, 1999Date of Patent: October 23, 2001Assignee: Confab Services AGInventor: Frank S.

Patent number: 6300538Abstract: An absorbent article (10) such as a sanitary napkin, having an elongate absorbent core (12) delimited by an upper surface (14) and a lower surface (16), a pair of opposed longitudinal edge portions (18, 20) terminating in longitudinal edges (22, 24), and a pair of opposed transverse edges (26, 28). The core has a first end portion (30), a second end portion (32) and a mid portion (34) located between the end portions. The article further includes a liquid permeable topsheet (36) extending over the upper surface (14) and a liquid impermeable sheet (38) covering the longitudinal edge portions (18, 20) of the absorbent core (12). A strip of generally hydrophobic resilient material (40) is placed between the liquid impermeable sheet (38) and the absorbent core (12) along each longitudinal edge portion (18, 20) of the absorbent core in at least the mid portion (34) to thereby increase the flexure resistance of the article.Type: GrantFiled: November 20, 1996Date of Patent: October 9, 2001Assignee: SCA Hygiene Products AktiebolagInventors: Bengt W.

Patent number: 6284943Abstract: A disposable absorbent article for wearing in an undergarment, such as a sanitary napkin, pantiliner, or incontinence pad is described. The absorbent article includes a topsheet, a backsheet, an absorbent core, and a stiffening feature. The stiffening feature places the absorbent article in an initially stiffened condition during placement of the article in an undergarment. After the article is subjected to the forces exerted by the body of the wearer, the stiffening feature no longer provides an increased initial stiffness and the article becomes more flexible.Type: GrantFiled: December 13, 1996Date of Patent: September 4, 2001Assignee: The Procter and Gamble CompanyInventors: Thomas Ward Osborn, III, Letha Margie Hines

Patent number: 6218593Abstract: An absorbent article includes a liquid permeable topsheet, a liquid impermeable back sheet, and an absorbent member interposed between the topsheet and the back sheet. While worn, the absorbent article forms a front waist body portion located at the front waist of a wearer and a rear waist body portion located at the rear waist of a wearer. The rear waist body portion has at each side thereof a fastening member for fastening the absorbent article, wherein the back sheet is made up of laminated sheeting composed of a finely porous resin film and nonwoven fabric. The fastening member is formed of a male sheet member of a mechanical fastener and designed to be brought into direct contact with the surface of the nonwoven fabric constituting the back sheet. The above-mentioned absorbent article has a good fit on a wearer, exhibits excellent leakproofness and breathability while worn, and has an excellent texture.Type: GrantFiled: April 15, 1997Date of Patent: April 17, 2001Assignee: Kao CorporationInventors: Yasuhiro Torimae, Tetsuya Masuki, Tetsuji Kitoh, Jun Sasaki, Manabu Kaneda

Patent number: 6168584Abstract: A spacer for use in a disposable absorbent article. The spacer is symmetric about a longitudinal axis and has two transversely oriented springs generally orthogonal to the longitudinal axis. The transversely oriented springs have different spring rates, so that transverse compression caused by the wearer's thighs may be readily accommodated, yet the spacer remain open to receive fecal material. The spacer may be advantageously used in a disposable absorbent article having a void space between the topsheet and the core, and maintain this void space under the weight of the wearer.Type: GrantFiled: August 15, 1996Date of Patent: January 2, 2001Assignee: The Procter & Gamble CompanyInventors: Patrick Jay Allen, Bret Alan Sims
