Patent number: 6703090Abstract: A heat insulating paper cup having an improved seal. The cup can include a body member having an inside surface and outside surface, and a bottom panel member having a upper surface and a bottom surface. The body member is coated (or in some instances partially coated) on its outside surface with a foamed low density polyethylene, and on its inside surface with an unfoamed modified low density polyethylene. The bottom panel member is coated on its upper surface with or an unfoamed low density polyethylene or foamed or unfoamed modified low polyethylene. The body member and bottom panel are oriented and joined to form a heat seal at an interface between a portion of the unfoamed modified low density polyethylene coated on the inside surface of the body member and a portion of unfoamed low density polyethylene or unfoamed modified low density polyethylene coated on the upper surface of the bottom panel member.Type: GrantFiled: April 18, 2002Date of Patent: March 9, 2004Assignee: Fort James CorporationInventors: Michael A.

Patent number: 6685074Abstract: A dispensing apparatus and method are disclosed for dispensing sheet material from at least one roll of the sheet material. Dispensing is transferred from a stub roll to a reserve roll automatically in response to sensing a predetermined quantity of the stub roll. An isolating element is provided to lift the reserve roll out of contact with dispensing rollers during dispensing of sheet material from the stub roll, and a nipping element is provided to nip sheet material of the reserve roll when dispensing is transferred from the stub roll to the reserve roll. A cam controls movement of both the isolating element and the nipping element. Structure is also provided for sensing the diameter of the reserve roll of sheet material and providing an indication when the reserve roll is a predetermined diameter. The dispenser is quiet and capacity efficient.Type: GrantFiled: February 21, 2002Date of Patent: February 3, 2004Assignee: Fort James CorporationInventors: Dale T.

Publication number: 20040000611Abstract: A powered dispenser for dispensing a perforated web of sheet material includes an internal well which holds a dispensed segment of the paper web for separation by a user. The well may include a concave portion attached to an elongated upwardly inclined portion that extends to a discharge opening. A separating member in the well is provided so that the dispensed segment can be pulled against it to separate the segment at the tear lines with a substantially reduced pull force. The separating member may have a symmetrical configuration and an asymmetrical configuration. The separating member is pivotally configured so as to rotate towards or away the discharge opening for actuating the feed mechanism when a force is applied to a portion of a dispensed segment.Type: ApplicationFiled: June 28, 2002Publication date: January 1, 2004Applicant: Fort James CorporationInventors: Bruce T.

Patent number: 6669821Abstract: The present invention is a method for maximizing water removal from an absorbent web in a press nip. The present invention uses a pressing unit having a blanket with a void volume and with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web. The improved pressure profile according to the present invention results in increased water removal and/or improved line speed. The void volume further increases water removal and/or improves line speed.Type: GrantFiled: November 14, 2001Date of Patent: December 30, 2003Assignee: Fort James CorporationInventors: Steven L. Edwards, Robert J. Marinack, Jeffrey Charles McDowell, Gary L. Worry
