Patent number: 8158047Abstract: A multi-ply tissue includes a first cellulosic embossed ply having an emboss pattern applied over a portion of its surface and a second cellulosic embossed ply of tissue. The first ply is contact laminated to the second ply so that the primary adhesion between the plies of tissue is the result of contact between cellulosic fibers. The first and second plies contact one another in contact areas, with the contact areas between the first and second plies defining compliant voids. The contact areas between the first ply and the second ply are elongated and/or rounded contact areas.Type: GrantFiled: August 10, 2010Date of Patent: April 17, 2012Assignee: Georgia-Pacific Consumer Products LPInventors: Galyn A. Schulz, Gary L. Worry, Kang Chang Yeh, Thomas N. Kershaw

Patent number: 7546973Abstract: A paper towel dispenser includes a housing with an inner chamber configured to support a paper supply and a dispensing aperture for dispensing paper from the paper supply. The paper supply includes a side that is formed by superimposed edge portions of paper from the paper supply. An indicator mechanism is affixed to the housing within the inner chamber and is disposed adjacent the paper supply. The indicator mechanism includes an indicator operably connected to a release mechanism. The indicator is movable between a retracted position and an indicating position. The release mechanism is pivotally biased away from the housing and is releasable in response to the paper supply being reduced below a predetermined amount. Upon release of the release mechanism, the release mechanism causes the indicator to move to the indicating position.Type: GrantFiled: September 2, 2008Date of Patent: June 16, 2009Assignee: Georgia-Pacific Consumer Products LPInventors: Gregory D.

Patent number: 6908059Abstract: A paper towel dispenser dispenses towels from a paper supply and includes a dispenser housing a low-reserve indicator mechanism for indicating when a reserve quantity of the paper supply is low. The dispenser housing has a housing wall structure on which the low-reserve indicator mechanism is affixed. The paper supply has vertically super imposed edge portions which form an outwardly facing vertical side of the paper supply. The low-reserve indicator mechanism includes an indicator mounted for movement between a retracted position and an indicating position for establishing a low-reserve indication detectable from outside of the dispenser house. The indicator mechanism also includes a release mechanism adapted to be spring-biased into contact with the vertical side of the paper supply. The release mechanism is released for movement in response to becoming unsupported by a diminishing height of the vertical side of the paper supply to cause the indicator to move to its indicating position.Type: GrantFiled: February 6, 2003Date of Patent: June 21, 2005Assignee: Fort James CorporationInventors: Gregory D.

Patent number: 6536624Abstract: Dispensable sheet material includes opposite side edges spaced apart from one another to define the overall width of the sheet material. Zones of weakness are spaced along the sheet material. Adjacent zones of weakness are spaced apart by a distance of from about 50% to about 200% of the overall width of the sheet material to divide the sheet material into a plurality of sheet material segments. Each of the zones of weakness comprises a plurality of perforations and frangible sheet material portions. Each of the frangible sheet material portions has a width of from about 0.3 mm to about 1.8 mm. The total width of the frangible sheet portions in each zone of weakness is from about 10% to about 30% of the overall width of the sheet material. The sheet material has an elasticity in the dispensing direction of from about 4% to about 20%. The sheet material has a dry tensile strength in the dispensing direction of from about 4,000 grams per 3 inches of width to about 12,000 grams per 3 inches of width.Type: GrantFiled: April 9, 2002Date of Patent: March 25, 2003Assignee: Fort James CorporationInventors: Douglas W.
