Publication number: 20100228218Abstract: A disposable pull-on garment has a front waist region and a back waist region opposite the front waist region. The disposable pull-on garment also has a chassis and front and back waist members attached to the chassis in the front and back waist regions, respectively. The front waist member has a first retraction force and the back waist member has a second retraction force. The disposable pull-on garment also has a pair of side members attaching the front waist region to the back waist region, thereby forming a waist opening and a pair of leg openings. Each of the pair of side members includes a waist zone and a hip zone. The waist zones have retraction forces which are about equal to the first retraction force, and the hip zones have retraction forces which are greater than the first or second retraction forces.Type: ApplicationFiled: May 18, 2010Publication date: September 9, 2010Inventors: Frederick Michael Langdon, Uwe Schneider, Christopher Jason Hawke, Gregory Ashton

Patent number: 7682350Abstract: A disposable absorbent article has a front waist edge, a back waist edge, a topsheet, a backsheet attached to at least a portion of the topsheet, and an absorbent core disposed therebetween. A waist member is attached to a wearer-facing surface of the disposable absorbent article or between the topsheet and the backsheet adjacent to the front waist edge and the back waist edge. The waist member is unattached to an outer-facing surface of the disposable absorbent article. The waist member extends outward from the front waist edge and the back waist edge such that at least a region of the waist member is visible from a vantage point external to the disposable absorbent article, thereby providing the appearance of a finished front waist edge or the appearance of a finished back waist edge.Type: GrantFiled: October 14, 2005Date of Patent: March 23, 2010Assignee: The Procter & Gamble CompanyInventors: Frederick Michael Langdon, Luke Robinson Magee, Gregory Ashton, Mark John Ciesko

Patent number: 7074215Abstract: A disposable garment having a localized retention zone for retention of the garment in its initial position on the body of a wearer. The retention zone has a higher coefficient of static friction than does the major area of the body-facing surface of the garment. The garment may also include localized areas having a lower coefficient of static friction than that of the major area to facilitate placement of the garment in a desired wearing position. Such lower coefficient of static friction areas can include the areas adjacent the leg openings and the area of the waistband that overlies the stomach of the wearer. Additionally, the garment can also include areas wherein the coefficient of static friction varies from high to low to provide improved retention and comfort over a wide range of wearing conditions and a wide range of movements of the wearer.Type: GrantFiled: June 5, 2003Date of Patent: July 11, 2006Assignee: The Procter & Gamble CompanyInventors: Gregory Ashton, Frederick Michael Langdon, David Joseph Kenneth Goulait, Julie Lyn Moore, Juan Carlos Velez

Patent number: 6764478Abstract: Absorbent article having a containment assembly and highly extensible leg openings. The leg opening margins may have portions having differential properties, such as differential elastic extensibility. The absorbent article may also have highly extensible outer leg cuffs. Additionally, the absorbent article may have a narrow crotch region. The absorbent article may thus provide ease of application and removal, sustained dynamic fit, prevention of leakage, sustained wearer comfort, and desirable appearance.Type: GrantFiled: June 29, 2001Date of Patent: July 20, 2004Assignee: The Procter & Gamble CompanyInventors: Gregory Ashton, Eiro Fukuda, Frederick Michael Langdon

Patent number: 6641568Abstract: Absorbent articles having improved sustained fit on the body, improved appearance through the period of use, and improved comfort for the wearer. The absorbent article has a containment assembly, a waist feature and a diagonal support member feature disposed so as to lie in the diagonal support zone of the wearer's body when the article is worn. The diagonal support member is designed to support the article from the small of the back, over the hip, and to the lower abdomen. The diagonal support member is distinct from the waist feature, which is designed to provide only enough circumferential tension to hold itself in position on the body. The absorbent article has a garment-like high-waisted appearance, gentle tension around the waist to avoid discomfort and/or pressure marking, good leakage protection, good sustained fit, and easy application and removal.Type: GrantFiled: January 18, 2001Date of Patent: November 4, 2003Assignee: The Procter & Gamble CompanyInventors: Gregory Ashton, Frederick Michael Langdon

Patent number: 6626879Abstract: A disposable absorbent garment having an elastic waist panel that includes one or more localized retention zones for retention the garment in its initial, as-applied position on the body of a wearer. The retention zones includes materials that have a higher coefficient of static friction than does the major surface area that constitutes the inner, body-facing surface of the garment. The garment can also include localized areas having a lower coefficient of static friction than that of the major inner surface area of the garment to facilitate placement of the garment in a desired wearing position. Such lower coefficient of static friction areas can include the areas adjacent the leg openings and the area of the waistband that overlies the stomach of the wearer.Type: GrantFiled: May 17, 1999Date of Patent: September 30, 2003Assignee: The Procter & Gamble CompanyInventors: Gregory Ashton, Frederick Michael Langdon, Vijay Rajagopalan, David Joseph Kenneth Goulait, Julie Lyn Moore, Juan Carlos Velez

Patent number: 6017018Abstract: An apparatus used to lift and lower an object, such as a canopy covering placed on a truck's opened bed. A T-shaped load engaging platform member has a vertically adjustable sleeve mounted on the platform's vertical member whose position on the member can be adjusted and fixed along its height. A combined winch and cable controlled pivoted arm assembly having two joined pivotally arms, one of which arms is pivotally mounted to a vertical stationary support structure at its other end, is used to vertically support the engaging platform member above the ground at the end opposite the stationary support. A single operator can both raise and lower a load supported on the platform by rotating a handle on the winch assembly and directing the movement of the supported load.Type: GrantFiled: March 2, 1998Date of Patent: January 25, 2000Inventor: Steven Michael Langdon
