Patent number: 5641524Abstract: An apparatus for plug-assisted thermoforming of a cup or other hollow article has a concave well or cone region machined into its top with a series of small holes drilled near the deepest part of the well and connected to a port inside the plug which is connected to a specifically sized manifold system. The manifold has a source for positive (pneumatic) and negative (vacuum) pressure air. During the machine cycle, a vacuum is introduced into the plug, which draws the hot plastic sheet into the plug well to stretch it. The vacuum is replaced by compressed air to transfer the pre-stretched sheet into a mold. In a particularly preferred embodiment, the plug is shaped to provide stretching in both the central well and in peripheral regions concentric with the well. Controlled air pressure in the mold may be used to provide the concentric prestretching.Type: GrantFiled: June 7, 1995Date of Patent: June 24, 1997Assignee: James River Corporation of VirginiaInventors: Jonathan E. Rush, John R. Johnson

Patent number: 5636452Abstract: A paper drying apparatus including a first rotatable drum, wherein the first rotatable drum has an inner perimeter and an outer perimeter and a second rotatable drum having an inner perimeter and an outer perimeter. A fabric sheet for carrying a paper web is provided, wherein the fabric sheet passes around the outer perimeter of the first rotatable drum and proceeds to next pass around the outer perimeter of the second rotatable drum. As the fabric sheet conveys the paper web around the first rotatable drum, a drying air is applied to the paper web in a direction from the inner perimeter of the first rotatable drum toward the outer perimeter of the first rotatable drum, further passing through the paper web. As the fabric sheet and paper web proceed around the second rotatable drum, a drying air is applied to the paper web in a direction from the outer perimeter of the second rotatable drum toward the inner perimeter of the second rotatable drum, further passing through the paper web in a similar direction.Type: GrantFiled: October 27, 1995Date of Patent: June 10, 1997Assignee: James River Corporation of VirginiaInventors: Benjamin A. Thorp, James Gilpatrick

Patent number: 5630526Abstract: A system for dispensing individual sheet material segments from a roll of sheet material in which the sheet material is separated into individual segments by perforated tear lines. The sheet material roll is continually positioned on support rollers with the lead end of the sheet material passing through a nip defined by the rollers and a member which is biased against the rollers to resist rotation thereof. After passing through the nip the end of the toweling proceeds through a restricted opening. Pulling of the end-most segment by a consumer causes the end-most segment to be separated along the perforated tear line separating it from the adjoining, following segment.Type: GrantFiled: October 31, 1995Date of Patent: May 20, 1997Assignee: James River Corporation of VirginiaInventor: John R. Moody

Patent number: 5624053Abstract: A disposable drink-thru lid for a drinking cup including an annular mounting portion for sealingly engaging the drinking cup, an annular trough provided about an inner periphery of the annular mounting portion as well as an annular side wall extending upwardly from the trough to a top land in the form of an annular ridge adjacent an uppermost extremity of the annular side wall is disclosed. The top portion of the lid includes a crown region having a periphery adjacent the annular ridge wherein the annular ridge is asymmetrical having a widened region accommodating a drink-thru opening and a narrowed region diametrically opposed to the widened region of the annular ridge. Further, the periphery of the crown region lies in a first substantially horizonal plane while the annular ridge includes a substantially planar surface with this surface lying in a plane above the planed defined by the periphery of the crown region thereby forming a retaining wall for retaining a container placed thereon.Type: GrantFiled: June 6, 1995Date of Patent: April 29, 1997Assignee: James River Corporation of VirginiaInventors: Mike Freek, Raya Berkovich

Patent number: 5609901Abstract: A perforated package of a composite integral sheet material which includes a first layer of absorbent material, a second layer of printable material and an impermeable pigmented polymer layer interposed between the first and second layers. The composite material has a plurality of air pockets formed between at least one of the first or second layers and the polymer layer, by discontinuously bonding the first or second layers to the polymer material. The package has two parallel lines of perforation which allow access to the interior of the package and to the foodstuff contained therein. A method of using the perforated package of composite integral material.Type: GrantFiled: February 9, 1995Date of Patent: March 11, 1997Assignee: James River CorporationInventors: Daniel J. Geddes, Kathy Rigotti, Linda L. Bunker, Arthur C. Berger, Patrick L. Maynard, Robert Patterson, David H. Hollenberg

Patent number: 5597639Abstract: The perceived softness of embossed tissue can be increased greatly while avoiding nesting when a particular pattern is embossed into the tissue. This pattern combines relatively shallow stitchlike bosses with deeper more sharply defined signature bosses. The stitchlike bosses can be rounded and arranged in wavy flowing intersecting lines. The signature bosses can be arranged in regions framed by the intersecting wavy flowing lines.Type: GrantFiled: December 20, 1993Date of Patent: January 28, 1997Assignee: James River Corporation of VirginiaInventor: Galyn A. Schulz
