The absorbent article includes a liquid permeable bodyside liner, a liquid-impermeable baffle, and first and second absorbents positioned between the liner and the baffle. The first absorbent is a stabilized material containing a superabsorbent and has a predetermined basis weight. The second absorbent is positioned below the first absorbent and contains a different superabsorbent from the superabsorbent present in the first absorbent. The second absorbent has a basis weight that is equal or greater than the basis weight of the first absorbent.Type: ApplicationFiled: May 11, 2001Publication date: November 14, 2002Inventors: Robert Rex Kirk, Jody Dorothy Suprise

Patent number: 6476289Abstract: Absorbent article such as disposable diapers, incontinent briefs, diaper holders and the like, that have a unique elastic waist feature that improves the dynamic fit of the elasticized waistband as well as the containment characteristics of the absorbent article. The elastic waist feature preferably comprises an interconnecting panel zone, a first flexural hinge zone joining the interconnecting panel zone with the containment assembly, an elasticized waistband, and a second flexural hinge zone joining the elasticized waistband with the interconnecting panel zone. The elasticized waistband comprises a shaping panel zone; a waistline panel zone; and a predisposed, resilient, waistband flexural hinge zone joining the shaping panel zone and the waistline panel zone.Type: GrantFiled: June 5, 1997Date of Patent: November 5, 2002Assignee: The Procter & Gamble CompanyInventors: Kenneth B. Buell, Sandra H. Clear, Danielia T. Falcone

Publication number: 20020147436Abstract: An absorbent tampon has improved ease of insertion into and removal from a body cavity. This is accomplished by covering at least a portion of the outer surface of the tampon with an apertured polymeric formed film. The apertured formed film provides a smooth land area on the outermost surface of the tampon for gentle, nondrying passage along the vaginal walls. The apertures in the film allow fluid to pass through the cover and into the absorbent core, where the fluid is held to prevent leakage.Type: ApplicationFiled: March 19, 2002Publication date: October 10, 2002Inventors: Carol Gell, Linda Pierson, Mary Yeganeh

Patent number: 6462253Abstract: An absorbent product comprising a liquid-permeable casing layer (402), a liquid-barrier layer (413) and an absorption element (416) which is enclosed between the liquid-permeable casing layer (402) and the liquid-barrier layer (413), and a liquid-transfer layer (403) which is disposed between the liquid-permeable casing layer (402) and the absorption element (406). The envelope layer (402) is bonded in a pattern of distinct thermally produced bonds (405) to the liquid-transfer layer (403). The liquid-transfer layer (403) comprises 40-65% by weight network-creating function fibres which are substantially intact following the bonding-together of the envelope layer (402) and the liquid-transfer layer (403) and which have a fibre coarseness ranging from 6 denier to 12 denier and 35-60% by weight fibres comprising a weldable, thermoplastic component and having a fibre coarseness of at least 3 denier.Type: GrantFiled: March 29, 2001Date of Patent: October 8, 2002Assignee: SCA Hygiene Products ABInventors: Ing-Britt Magnusson, Peter Hedenberg

Publication number: 20020143305Abstract: An apertured film cover for an absorbent article is disclosed. The cover has an additive combination comprising a hydrophilic agent and a lyophilic agent applied thereto. The additive combination provides surprisingly improved fluid transfer across the cover. It can also provide a benefit by reducing frictional forces during the manufacture of a tampon.Type: ApplicationFiled: December 21, 2000Publication date: October 3, 2002Inventors: Ching-Yun Morris Yang, Dietmar Van Loyen, Anthony DiSalvo

Publication number: 20020143306Abstract: A highly breathable, stretch-thinned film having enhanced breathability includes a matrix polymer, a particulate filler, and an incompatible polymer that is thermodynamically incompatible with the matrix polymer. The incompatible polymer can be added to the film in the form of laminate waste material.Type: ApplicationFiled: February 16, 2001Publication date: October 3, 2002Inventors: John David Tucker, Bryon P. Day

Publication number: 20020133131Abstract: A soft, high density, absorbent material is provided with improved characteristics. A process is provided for making the absorbent material. A web is formed from material that includes a mixture of cellulosic fibers and synthetic polymer fibers. Then, the web is preferably compacted and embossed at an elevated temperature to further increase the web density and preferably to also create liquid-stable bonds between the synthetic polymer fibers and the cellulosic fibers in spaced-apart regions of the web.Type: ApplicationFiled: January 9, 2001Publication date: September 19, 2002Inventors: Krishnakumar Rangachari, Kays Chinai
