Patent number: 8905989Abstract: An intravaginal tampon is formed of compressed material and has an outer surface, an insertion end, a withdrawal end, and a center portion formed between the insertion and withdrawal ends. The outer surface has at least two segmented grooves are formed therein, and each segmented groove is separated from and spaced at a distance from an adjacent segmented groove. Each segmented groove has at least one substantially longitudinal segment and at least one accumulator segment. The arrangement of the segments provides a pooling region to impede bodily fluid flow along the outer surface of the tampon.Type: GrantFiled: March 27, 2013Date of Patent: December 9, 2014Assignee: McNeil-PPC, Inc.Inventors: Paul Y. Fung, Dmitry Yavich

Patent number: 6812169Abstract: A personal care absorbent article, such as a sanitary pad or napkin, wound dressing, and the like having an absorbent material treated with a fluid treatment agent, which fluid treatment agent causes red blood cells in a blood-containing fluid to agglomerate or lyse as the fluid passes into and/or through the absorbent article. In accordance with one preferred embodiment, the absorbent material is a porous nonwoven web material.Type: GrantFiled: November 9, 2001Date of Patent: November 2, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: David Charles Potts, Jack Nelson Lindon, Emmanuelle Cecile Damay, Dmitry Yavich, Matthew David Young

Patent number: 6627789Abstract: There is provided an intake/retention/transfer material for personal care products like feminine hygiene products, which is a heterogeneous composite containing between 5 and 25 weight percent of a superabsorbent or gelling material and having a density less than 0.17 g/cc. A more particular embodiment contains less than 20 weight percent and a still more particular embodiment contains 15 weight percent or less of a superabsorbent or gelling material. Also provided are absorbent articles which contain the class of intake/transfer materials mentioned above along with additional absorbent layers such that the absorption of a menses simulant provides fluid partitioning of less than 72% of fluid in the intake/transfer/retention composite. Additionally said composite should have retention capacity values greater than 2.7 g/g.Type: GrantFiled: September 1, 2000Date of Patent: September 30, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Thomas William VanDenBogart, Amy Michele Achter, Bruce Wilfuhr Achter, Barbara Jean Burns, Michael Allen Daley, Peter Robert Elliker, David Martin Jackson, Nancy Donaldson Kollin, Gregory Marc Lefkowitz, Sylvia Bandy Little, Tamara Lee Mace, David Michael Matela, Cynthia Marie Phillips, David Charles Potts, Lawrence Howell Sawyer, Michael William Veith, Kevin Wilson Wood, Dmitry Yavich

Publication number: 20030149415Abstract: A wet-formed composite defining latent voids and macro-cavities, the wet-formed composite having a basis weight greater than about 100 grams per square meter and a density of about 0.06 grams per cubic centimeter or more. The wet-formed composite comprises fibers and superabsorbent material, with the superabsorbent material present in an amount of about 10 dry weight percent or less, specifically about 5 dry weight percent or less, and particularly about 2 dry weight percent or less, but more than 0, based on the total dry weight of fibers and superabsorbent material present in the wet-formed composite. By virtue of the superabsorbent material having been allowed to swell and then shrink during the making of the wet-formed composite, macro-cavities are created. Densification compresses the macro-cavities. The resulting composite expands upon wetting and exhibits good absorbency properties.Type: ApplicationFiled: February 21, 2003Publication date: August 7, 2003Inventors: Palani Raj Ramaswami Wallajapet, Ronald Lee Edens, Cheryl Ann Mocadlo, Sheng-Hsin Hu, Dmitry Yavich, David Michael Kale

Publication number: 20030149411Abstract: An absorbent article includes a vapor permeable backsheet, a liquid permeable topsheet positioned in facing relation with the backsheet; and an absorbent body located between the backsheet and the topsheet. The absorbent body may include multiple zones of high air permeability or may include materials which provide improved air exchange after being wetted. The absorbent article may also include a ventilation layer between the absorbent body and the backsheet and a surge management layer between the absorbent body and the topsheet. The article exhibits improved air exchange within the article during use. As a result, the article exhibits substantially reduced levels of hydration of the wearer's skin when in use which renders the skin less susceptible to the viability of microorganisms.Type: ApplicationFiled: February 28, 2003Publication date: August 7, 2003Inventors: Charles Paul Keuhn, Ronald Lee Edens, Peter Robert Elliker, Michael John Faulks, Sheng-Hsin Hu, Debra Jean McDowall, Shannon Kathleen Melius, Cheryl Ann Mocadlo, Cynthia Marie Phillips, Cathleen Mae Uttecht, Palani Raj Ramaswami Wallajapet, Dmitry Yavich, David Louis Zenker, Frank Jerrel Akin, Margaret Gwyn Latimer, Pamela Jean Mayberry, Susan Carol Paul, Audra Stefanik Wright
