Patent number: 11925537Abstract: The present disclosure relates to stranded elastomeric laminates (including bi-laminates and tri-laminates) comprising beamed elastics and may have inventive Dtex-to-Nonwoven-Basis-Weight-Ratios, Dtex-to-Spacing-Ratios, and/or Void-Area-to-Strand-Area-Ratios. The stranded laminates of the present disclosure may be used for disposable absorbent article components (including pant belts) and may comprise inventive bonding arrangements that yield inventive textures and texture arrangements. When the inventive stranded elastomeric laminates are used for pant belts, the pants may have inventive Application-Forces, Sustained-Fit-Load-Forces, and Sustained-Fit-Unload-Forces. Further, when absorbent articles are packaged under compression at inventive In-Bag-Stack-Heights, the stranded elastomeric laminates of the present disclosure maintain their inventive properties and characteristics, including their inventive textures.Type: GrantFiled: September 15, 2021Date of Patent: March 12, 2024Assignee: The Procter & Gamble CompanyInventors: Gary D.

Patent number: 6605070Abstract: An absorbent article includes a liquid impervious backsheet joined to a liquid permeable topsheet with an absorbent core disposed therebetween. The joined topsheet and backsheet includes an extensible portion that is non-elastically, laterally extensible having a percent elongation of at least about 125%. A pair of elastomeric side panels is joined to a portion of the joined topsheet and backsheet near the extensible portion. Each of the side panels is elastically laterally extensible such that the force required to elongate the side panels a select percent elongation is less than the force required to elongate the extensible portion of the joined topsheet and backsheet an equivalent select percent elongation.Type: GrantFiled: June 29, 2001Date of Patent: August 12, 2003Assignee: The Procter & Gamble CompanyInventors: Susan J.

Patent number: 6488202Abstract: A device and method are described for identifying the size of a disposable diaper or absorbent article which is appropriate in terms of proper fit for a potential wearer of the article. The device and method employ information regarding at least two different selected characteristics of potential wearers and an association between such information and a size of the article which is fit-appropriate for a potential wearer. The size identification is more reliable than an identification which is based solely upon a single characteristic of the potential wearer.Type: GrantFiled: March 31, 2000Date of Patent: December 3, 2002Assignee: The Procter & Gamble CompanyInventors: Bret D. Seitz, Gary D. Lavon, David M. Weirich

Patent number: 6458110Abstract: An absorbent article having an expandable component. The expandable component comprises a compressed, resilient element disposed within an air impermeable envelope. The compressed element provides the absorbent article with a thin, low bulk profile prior to use of the disposable absorbent article, thereby reducing shipping and storage space. The user may open the impervious envelope, thereby permitting entry of air into the envelope and expansion of the compressed element. In one embodiment the expandable component is a spacer for maintaining fecal void space in a disposable diaper. Alternatively, the expandable component can provide displacement of the topsheet relative to the backsheet along the longitudinal centerline of a sanitary napkin.Type: GrantFiled: January 11, 2000Date of Patent: October 1, 2002Assignee: The Procter & Gamble CompanyInventors: Gary D. Lavon, William R. Vinnage, Jr., Letha M. Hines, Donald C. Roe, Brandon E. Wise

Patent number: 5997521Abstract: Absorbent articles such as disposable training pants, pull-up diapers, incontinence briefs, diaper holders, feminine hygiene garments, and the like, having extensible side panel features that improve the dynamic fit of the diaper around the legs and waist of the wearer. Such absorbent articles include a containment assembly including a liquid pervious topsheet; a liquid impervious backsheet; an absorbent core disposed between the topsheet and the backsheet; and extensible side panels, each including a waist panel and a thigh panel disposed along each longitudinal edge of the containment assembly in the first waist region. The waist panel and the thigh panel are operatively associated so that the waist panel has a primary direction of extensibility in one direction and the thigh panel has a primary direction of extensibility in a different direction.Type: GrantFiled: October 3, 1996Date of Patent: December 7, 1999Assignee: The Procter & Gamble CompanyInventors: Miguel A. Robles, Carl L. Bergman, Donald C. Roe, Kimberly A. Dreier, Gary D. Lavon, Thomas A. Desmarais

Patent number: 5634916Abstract: Absorbent articles such as diapers, incontinent briefs, training pants, diaper holders and liners, feminine hygiene garments, and the like, designed to provide sustained dynamic fit about the wearer during use as well as to improve the containment of body exudates and wearer comfort/mobility. Such an absorbent article has an absorbent core preferably designed to fit within the low motion zone of the wearer so that dynamic forces imparted by movements of the wearer on the absorbent core are minimized. The absorbent article is also provided with a closure system for anchoring the absorbent article on the wearer to sustain the dynamic fit of the absorbent article throughout wearing. The closure system is designed so that a primary line of tension, fitting at an angle to the body, is formed to secure the absorbent article on a wearer.Type: GrantFiled: June 6, 1995Date of Patent: June 3, 1997Assignee: The Procter & Gamble CompanyInventors: Gary D. Lavon, Edward P. Carlin, Kenneth B. Buell, Thomas A. Desmarais, John A. Chang, Christina S. Mueller, Takako Haga

Patent number: 5632737Abstract: Absorbent foams materials that are capable of acquiring and distributing aqueous fluids, especially discharged body fluids such as urine. These absorbent foams combine relatively high capillary absorption pressures and capacity-per-weight properties that allow them to acquire fluid, with or without the aid of gravity. These absorbent foams also give up this fluid efficiently to higher absorption pressure storage materials, including foam-based absorbent fluid storage components, without collapsing. These absorbent foams are made by polymerizing high internal phase emulsions (HIPEs).Type: GrantFiled: May 14, 1996Date of Patent: May 27, 1997Assignee: The Procter & Gamble CompanyInventors: Keith J. Stone, Thomas A. DesMarais, Gary D. LaVon, Stephen A. Goldman, Paul Seiden
