Publication number: 20080132865Abstract: Aspects of the present disclosure involve patterns on substrate surfaces, such as nonwoven webs or fabrics, plastic films, and laminates thereof, that cause the substrate surfaces to exhibit a three-dimensional appearance. In some embodiments, the three-dimensional appearance of the substrate surface resembles protrusions and indentions indicative of threads in woven cloths. The patterns are created by printing a surface of a substrate, as opposed to deforming the substrate such as by embossing. Embodiments of the patterns include a plurality of repeating shapes or macro-units disposed on the substrate surface.Type: ApplicationFiled: November 29, 2007Publication date: June 5, 2008Inventors: Wenbin Li, George Christopher Dobrin, Ada Ho Yau Ko, Douglas Joseph Meyer, Alrick Vincent Warner, Kathleen Marie Lawson, Jonathan Aaron Lu, Angelli Sue Denmon

Publication number: 20080132866Abstract: An elastic nonwoven composite that contains an elastic film laminated to one or more nonwoven web materials is provided. The composite is formed by passing the film through a nip to bond the film to the nonwoven web material(s). Concurrent with bond formation, apertures are also formed in the elastic film. The apertures are of a size sufficient to provide a desired level of texture, softness, hand feel, and/or aesthetic appeal to the composite without having a significant adverse effect on its elastic properties. Aperture and bond formation are accomplished in the present invention by selectively controlling certain parameters of the lamination process, such as film content, bonding pattern, degree of film tension, bonding conditions, etc.Type: ApplicationFiled: February 11, 2008Publication date: June 5, 2008Applicant: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Jose Siqueira, Ann L.

Publication number: 20080132861Abstract: A disposable urine collection device may include an absorbent pad disposed proximate to the inner surface of a shell. The device may be contoured to be positioned against and enclose the urinary area of a user such that the absorbent pad may absorb a quantity of urine associated with a complete urinary discharge from the user. The absorbent pad may be formed from one or more commercially available diapers. One or more elastic cuffs may be provided to conform to the user's urinary area and to help contain the flow of urine as it is discharged from the user. An invertible bag may be attached to the bottom of the shell so that the user may conveniently enclose the absorbent pad after use and dispose of the device in a sanitary manner.Type: ApplicationFiled: November 7, 2006Publication date: June 5, 2008Inventors: Kimberly L. Tomes, Theresa Ernest

Publication number: 20080125734Abstract: A method of making a pouch-like container product for absorbing liquids comprises joining a first sheet having SAP particles preferably adhered to a first surface with a second sheet to form a container partially filled with such particles. The application of pressure, for example by passing the product through a roll nip, facilitates joining of the sheets and causes the particles to break through at least the one of the sheets to create an opening whereby free volume is created to permit the particles to expand when in contact with a liquid. The resultant product is also described. In an additional product embodiment non-SAP particles may be utilized to break through the sheet(s) and preformed openings may also be included in the sheet(s). Additional SAP material may be placed in between the sheets of the product.Type: ApplicationFiled: November 28, 2006Publication date: May 29, 2008Inventors: Jeno Muthiah, Gerald K. White, Duane R.

Publication number: 20080125735Abstract: An absorbent article, preferably a disposable absorbent article such as a diaper, is disclosed having an absorbent core which imparts increased wearing comfort to the article and makes it thin and dry. The absorbent core useful for an absorbent article comprises a substrate layer, a discontinuous layer of absorbent material, and a layer of thermoplastic material. A second surface of the discontinuous layer of absorbent material is in at least partial contact with a first surface of the substrate layer. Portions of a second surface of the layer of thermoplastic material are in direct contact with the first surface of the substrate layer and portions of said second surface of the layer of thermoplastic material are in direct contact with a first surface of the discontinuous layer of absorbent material. A process for providing a storage layer for an absorbent core useful in an absorbent article is further disclosed.Type: ApplicationFiled: October 10, 2007Publication date: May 29, 2008Inventors: Ludwig Busam, Uwe Jurgen Becker, Michael Divo, Bruno Johannes Ehrnsperger, Roland Engel, Torsten Lindner, Siegfried Link, Volker Maier, Sanaul Kabir Siddiquee, Gabriele Stiehl, Thomas Tombuelt

Patent number: 7378567Abstract: An absorbent body for hygiene articles, particularly sanitary napkins or panty liners, includes a liquid absorbing and distributing layer facing the body and made of a first fibrous material with a first pore size, and a liquid storage layer facing away from the body and including at least 20 to 98 wt. % cellulose fibers, with a second pore size smaller than the first pore size. The first fibrous material is made of interlinked cellulose fibers, and the layers are interconnected, without adhesives by a multitude of embossing points provided in grid-like manner which results in the formation of a funnel-shaped pore gradient in the liquid absorbing and distributing layer around the embossing points. This pore gradient assists in the introduction of liquid into the underlying storage layer.Type: GrantFiled: July 25, 2002Date of Patent: May 27, 2008Assignee: Paul Hartmann AGInventor: Rainer Mangold

Patent number: 7378568Abstract: An absorbent article having a topsheet and an absorbent core material. The acquisition distribution layer is located between the topsheet and the absorbent core material. The acquisition distribution layer is made of a three dimensional apertured film that defines a large void volume space between the acquisition distribution layer and the absorbent core material. The acquisition distribution layer provides high void volume for lateral spillage during repeated insult moments because the topsheet, which is in contact with the user, is held away from dispersing fluid that is unabsorbed by saturated core material. The void volume space provides a pathway for unabsorbed fluid to flow over the top plane of saturated core regions to unsaturated regions of the core material for absorption. The void volume space allows this migration of fluid to occur without the fluid coming into contact with the topsheet, thereby avoiding a feeling of wetness for a wearer.Type: GrantFiled: June 20, 2003Date of Patent: May 27, 2008Assignee: Tredegar Film Products CorporationInventors: Paul Eugene Thomas, Thomas Patrick Marsh
