Patent number: 5647863Abstract: An absorbent article, such as a sanitary napkin, comprising a topsheet, a backsheet, and an absorbent core is described. The absorbent core comprises an acquisition member, a storage/distribution member, and an indicator member.

Patent number: 5607414Abstract: Thermally bonded absorbent structures for catamenial products, in particular catamenial pads, that provide improved ability in acquiring, distributing and storing aqueous body fluids, especially menstrual fluids, as well as better fit and comfort for the user of the products. These structures comprise an optional thermally bonded secondary topsheet, a thermally bonded absorbent core having a relatively higher capillary suction primary fluid distribution layer, an optional but preferred relatively lower capillary suction secondary distribution layer, a storage layer having absorbent gelling material, and an optional fibrous "dusting" layer. These thermally bonded absorbent structures are particularly useful with catamenial pads having a primary fluid pervious topsheet selected from apertured formed film topsheets and high loft nonwoven topsheets.Type: GrantFiled: July 3, 1995Date of Patent: March 4, 1997Assignee: The Procter & Gamble CompanyInventors: Mark R.

Patent number: 5382245Abstract: The present invention provides absorbent articles, especially sanitary napkins, containing a fluid transport layer. In-use, the transport layer directs menses to a storage layer, thereby minimizing product failure and staining of undergarments. The transport layer can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges. Preferably, the transport layer is a layer of fibers having external capillary channels.Type: GrantFiled: July 23, 1992Date of Patent: January 17, 1995Assignee: The Procter & Gamble CompanyInventors: Hugh A. Thompson, Gerald A. Young, Thomas W. Osborn, III, Charles W. Chappell, Theresa L. Johnson, John L. Hammons, Bruce W. Lavash, James C. Horney, Lee M. Hines

Patent number: 5356405Abstract: Absorbent articles, especially sanitary napkins, contain fibers with intra-fiber capillary channels. In-use, the capillary channel fibers direct menses to a storage layer, thereby minimizing product failure and staining of undergarments. The capillary channel fibers can protrude into, or through, a topsheet to provide very aggressive transport of vaginal discharges.Type: GrantFiled: April 6, 1993Date of Patent: October 18, 1994Assignee: The Procter & Gamble CompanyInventors: Hugh A.

Patent number: 5334176Abstract: Curled, twisted cellulosic fibers are reduced in size by mechanical means, i.e., by refining. The refined fibers are formed into sheets which are used as an absorbent layer in diapers, bandages and, especially, in sanitary napkins. In one mode, the refined fibers can be used to provide shaped sanitary devices. In an optional mode, fibers having intra-fiber capillary channels can be used to direct fluids into absorbent sheets comprising the refined, curled cellulosic fibers.Type: GrantFiled: July 23, 1991Date of Patent: August 2, 1994Assignee: The Procter & Gamble CompanyInventors: Daniel E. Buenger, James C. Horney, John L. Hammons
-
Patent number: H1511Abstract: The present invention provides absorbent articles, especially sanitary napkins, containing a flow regulator positioned between the topsheet and the absorbent core. In-use, fluid deposited on the topsheet is internally moved in the longitudinal direction by the flow regulator before being released to the absorbent core. By moving substantial amounts of fluid in the longitudinal direction the flow regulator provides a more effective use of the absorbent core.Type: GrantFiled: September 10, 1992Date of Patent: December 5, 1995Inventors: Charles W. Chappell, Lee M. Hines, John L. Hammons, Theresa L. Johnson

Patent number: H1614Abstract: A compound sanitary napkin including a primary absorbent member and a secondary absorbent member. The primary absorbent member has a length and a width. The secondary absorbent member has a length and a width. The primary absorbent member and the secondary absorbent member have a common length. The primary absorbent member includes an absorbent core and a fluid pervious topsheet superposed on the absorbent core. The secondary absorbent member includes a fluid pervious topsheet, a fluid impervious backsheet joined to the topsheet and an absorbent element positioned between the topsheet and the backsheet. The primary absorbent member is affixed to the secondary absorbent member by union means in such a manner that the longest unattached distance between adjacent points of attachment is less than 75% of the common length.Type: GrantFiled: August 19, 1994Date of Patent: November 5, 1996Inventors: Katherine L. Mayer, Bruce W. Lavash, John L. Hammons, Patricia L. Lampson

Patent number: H1657Abstract: An absorbent article for the management of body exudates having in combination, an acquisition component and a storage component. The acquisition component, interposed between the source of body exudates and the fluid storage component, has a member for fractionating body exudates emanating from the source and for storing the solid portion of the body exudates. The acquisition component has a plurality of pores in the size range of red blood cells, suspended solids, and other body exudates which traps, and stores the solid portion of body exudates and allows the fluid portion to continue flowing through the acquisition component and into the storage component. The storage component is for storing the fluid portion of the body exudates.Type: GrantFiled: February 3, 1995Date of Patent: June 3, 1997Assignee: The Procter & Gamble CompanyInventors: John L. Hammons, James C. Horney
