Patent number: 11160695Abstract: The present invention relates to disposable absorbent articles such as sanitary napkins, panty liners, baby diapers, adult incontinence articles and sweat pads. According to the present invention the absorbent article in the region designated for liquid deposition on its wearer facing surface has a single layer topsheet onto which liquid to be absorbed is provided during use of the article. The absorbent article includes a backsheet forming the liquid barrier surface and a unitary absorbent core between the topsheet and the backsheet. Importantly the unitary core provides improved liquid handling to the absorbent article and increases the masking, i.e. ability to hide stains due to absorbed liquid, of the article. This is particularly beneficial in the context of articles for absorption of liquids with high color intensity, such as menstrual liquid or urine of older adults.Type: GrantFiled: June 28, 2018Date of Patent: November 2, 2021Assignee: The Procter & Gamble CompanyInventors: Pietro Febo, Luigi Marinelli

Patent number: 9534325Abstract: Absorbent members and methods of making the same are disclosed. In one embodiment, the absorbent member is a unitary absorbent fibrous web having a density profile through its thickness. In one embodiment, the density profile of the fibrous web is skewed toward one of the surfaces of the fibrous web. In such embodiments, the maximum density of the web may be located outside of the central 30% zone of the thickness of the web. In one embodiment, the method involves subjecting a precursor web to at least one cycle (or pass) through a mechanical deformation process. Typically, the method involves subjecting the precursor web to multiples cycles (or passes) through a mechanical deformation process.Type: GrantFiled: April 26, 2011Date of Patent: January 3, 2017Assignee: The Procter & Gamble CompanyInventors: Jill Marlene Orr, Luigi Marinelli, John Brian Strube, Keith Robert Priessman, Carmine Cimini, Mario Dipilla

Patent number: 9452094Abstract: Absorbent members and methods of making the same are disclosed. In one embodiment, the absorbent member is a unitary absorbent fibrous web having a density profile through its thickness. In such an embodiment, the density profile may be relatively centered through the thickness of the web and the maximum density of the web is located between about 35% and about 65% of the distance through the thickness of the web.Type: GrantFiled: April 25, 2012Date of Patent: September 27, 2016Assignee: The Procter & Gamble CompanyInventors: Luigi Marinelli, Kirk Wallace Lake, Jill Marlene Orr, Paul Thomas Weisman, Carmine Cimini, Mario Dipilla, Keith Robert Priessman
