A chassis of the absorbent garment includes an outer cover and a body side liner with at least one elastomeric member folded within the body side liner around each of two leg openings defined by the chassis to form a finished edge around each leg opening. The folded edge of the body side liner is then folded again to create a fully functional flap with the appearance of a leg elastic in the crotch area. The resulting absorbent garment has a three-dimensional leg elastic assembly that creates a bucket for containing body fluids, and furthermore, creates a tailored, soft, comfortable leg and side seal.Type: GrantFiled: December 28, 2000Date of Patent: April 6, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Robert Lee Popp, Kathleen Irene Ratliff

Patent number: 6664440Abstract: A disposable undergarment is provided on inside of a waist-opening's peripheral edge with a sweat-absorbent sheet comprising an inner layer destined to come in contact with a wearer's skin and an outer layer opposed to the inner layer. The inner layer contains hydrophobic fibers of 70˜98 w % and hydrophilic fibers of at least 2 w %. The outer layer contains hydrophilic fibers of 50˜100 w % of which a part extends outward from the outer layer through interstices of the hydrophobic fibers to the skin contacting surface of the inner surface.Type: GrantFiled: May 24, 2001Date of Patent: December 16, 2003Assignee: Uni-Charm CorporationInventors: Kouji Kawamura, Yoshio Ono

Patent number: 6648869Abstract: An absorbent article such as a diaper includes a backsheet layer, a substantially liquid-permeable liner layer, and an absorbent body located between the backsheet and the liner. The backsheet and liner layers generally define a front waistband section, a rear waistband section, and an intermediate section, with the intermediate section interconnecting the front and rear waistband sections. The liner includes a plurality of spaced apart longitudinal upstanding ridges located at least in the intermediate section to provide barriers to transverse migration of body exudates. The upstanding ridges are formed by providing a plurality of laterally spaced apart and alternating longitudinally adhered liner portions and unadhered liner portions. Elastic members are located subjacent the unadhered portions and include a front end, a rear end, and a central portion disposed between the front and rear ends.Type: GrantFiled: December 30, 1996Date of Patent: November 18, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Ian W. Gillies, Daniel R. Schlinz

Patent number: 6641568Abstract: 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: GrantFiled: January 18, 2001Date of Patent: November 4, 2003Assignee: The Procter & Gamble CompanyInventors: Gregory Ashton, Frederick Michael Langdon

Patent number: 6638262Abstract: A disposable wearing article includes a substantially liquid-impervious leak-barrier cuff which has a fixed end portion lying in the vicinity of a longitudinal end portion of an article, a free end portion extending from the fixed end portion toward a crotch region and fixed lateral end portions lying on transversely opposite side edge portions of the article. The free end portion is normally biased to rise on a topsheet and locally bonded to the article in retaining zones.Type: GrantFiled: October 15, 2001Date of Patent: October 28, 2003Assignee: Uni-Charm CorporationInventors: Seiji Suzuki, Takaaki Shimada

Patent number: 6623467Abstract: A reusable diaper is made of two sheets of fabric. One sheet is an absorbant rectangular sheet. The second sheet is an inverted bell-shape and may be of resilient material. The absorbant sheet is stitched along one edge to the bell-shaped sheet along the length of the axis of symmetry of the bell-shaped sheet. The absorbant sheet is only stitched to the bell-shaped sheet adjacent one comer of the absorbant sheet so that, when unfolded, the absorbant sheet is at least twice the length of the axis of symmetry of the bell-shaped sheet. The absorbant sheet may thus be folded into a narrow rectangular absorbant pad lying along the axis of symmetry of the bell-shaped sheet. The opposite tapered ends of the bell-shaped sheet are wrapped around an infant's waist and are drawn to the front of the infant through a loop on the vertex of the bell-shape once the vertex has pulled lifted up between the infant's legs.Type: GrantFiled: October 12, 2000Date of Patent: September 23, 2003Inventor: Lotta Charles-Lundaahl

Patent number: 6605070Abstract: An absorbent article includes a liquid impervious backsheet joined to a liquid permeable topsheet with an absorbent core disposed therebetween. The joined topsheet and backsheet includes an extensible portion that is non-elastically, laterally extensible having a percent elongation of at least about 125%. A pair of elastomeric side panels is joined to a portion of the joined topsheet and backsheet near the extensible portion. Each of the side panels is elastically laterally extensible such that the force required to elongate the side panels a select percent elongation is less than the force required to elongate the extensible portion of the joined topsheet and backsheet an equivalent select percent elongation.Type: GrantFiled: June 29, 2001Date of Patent: August 12, 2003Assignee: The Procter & Gamble CompanyInventors: Susan J.
