Patent number: 7955670Abstract: A method of making a texture-coated and/or insulation coated container from a flat paperboard blank in which a heat-hardenable liquid polymeric binder texturizing and/or insulating agent coating mixture is applied to one surface of the blank in a pattern of covered and open areas. This coating mixture is subjected to heat to cure the polymeric binder and expand the texturizing and/or insulating agent, optionally treated with moisture, and optionally heated to form the blank into the shape of a container, and the container produced by this method. The containers such as cups, plates, etc., are useful in food service. These containers have a coefficient of static friction which is about 0.2 to 2.0 and over and a kinetic coefficient of friction which is about 0.22 to 1.5.Type: GrantFiled: April 10, 2007Date of Patent: June 7, 2011Assignee: Dixie Consumer Products LLCInventors: Dean P. Swoboda, Kenneth J. Shanton, Erland R. Sandstrom

Patent number: 7938294Abstract: A large capacity napkin dispenser for in counter mounting includes: (a) an elongate housing having a generally rectangular cross-section for receiving a stack of napkins; (b) a faceplate with a dispensing aperture, the faceplate being hinged to the housing so as to be movable between an open position for re-loading and a closed position for dispensing; (c) a movable support member mounted in the housing; (d) biasing means for urging the movable support toward the faceplate so that the stack of napkins is advanced to the aperture as it is depleted; and (e) sequestered means for locking the faceplate in the closed position. The locking means includes release means located adjacent the inner surface of the faceplate such that when the faceplate is in the closed position the release means is concealed in the interior of the dispenser, thereby eliminating the need for a key.Type: GrantFiled: July 21, 2009Date of Patent: May 10, 2011Assignee: Georgia-Pacific Consumer Products LPInventors: Antonio M. Cittadino, David R. Maroney, Brent J. Burns, Karl D. Kissinger, Andy L. Kirkpatrick, Michael R. Kilgore, Gregory D. Budz

Patent number: 7045559Abstract: A composition providing electrically conductive adhesive hydrogels suitable for use as skin contact adhesives and, particularly, suitable for use as an electrical interface for disposable medical devices. The present hydrogels provide for reduced skin irritation and/or malodor properties, hydrate a subject's skin, readily wet around a subject's skin surface hair, and protect against burning of a subject upon or due to electrical stimulation through the hydrogel. These hydrogels generally include a monomer, a first initiator, a solubilizer, and a cross-linking agent. The present hydrogels also desirably include a buffer system to help prevent discoloration of the hydrogels and/or hydrolysis of the hydrogels as well as to improve shelf-life. Other additives such as conductivity enhancers, pharmaceuticals, humectants, plasticizers, skin health agents, etc. may be added to the present hydrogels either before or after curing.Type: GrantFiled: December 18, 2003Date of Patent: May 16, 2006Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Ali Yahiaoui, Caron Keller, Richard Arnold Borders

Patent number: 6783976Abstract: A diagnostic system may include a carrier having at least one well, an upper surface, and a cavity extending downwardly from the upper surface. A specimen-handling tool may be configured to be positioned within the cavity and may include an elongated body having a longitudinal axis that extends along the length of the elongated body, a first end comprising an outermost portion adapted to skewer a tissue biopsy specimen.Type: GrantFiled: December 21, 2001Date of Patent: August 31, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Kristy Peterson, Donald J. McMichael

Patent number: 6777056Abstract: Composite nonwoven webs are provided having two distinct regions extending adjacent one another in the machine direction of the web; the first region is formed from first continuous filaments and the second region is formed from second continuous filaments. The interface of the first and second region is formed from a mixture the first and second continuous filaments in a confluent relationship with one another and such that the two distinct regions form a unitary nonwoven web. The respective first and second regions can have distinct physical attributes as a result of utilizing first and second filaments which are different from one another. The first and second continuous filaments can vary with respect to average fiber denier, cross-sectional shape, cross-sectional configuration, polymer composition, crimp level, and additive composition.Type: GrantFiled: October 12, 2000Date of Patent: August 17, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Lavada Campbell Boggs, Kevin George Hetzler, Glen Thomas Mildenhall, Michael Tod Morman, Dan Kenneth Schiffer, Susan Elaine Shawver, Sandy Chi-Ching Tan

Patent number: 6727196Abstract: The present invention relates to a composite material including a substrate with a first and a second layer, and a surfactant. The surfactant is applied to the first layer of the substrate. The surfactant acts to lower the surface tension of a fluid which contacts the first layer of the substrate such that the fluid is allowed or more readily enabled to pass through the first layer of the substrate, but such that the surfactant does not substantially adversely effect the absorption capacity or wicking height of the second layer of the substrate, as the second layer of the substrate substantially inactivates the surfactant upon contact or interaction therewith.Type: GrantFiled: August 31, 2001Date of Patent: April 27, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Ali Yahiaoui, Bernard Cohen, Joel Brostin, Michael Tod Morman

Patent number: 6610383Abstract: The present invention is directed to a necked laminate and a process for making the laminate. The necked laminate is formed from sheet layers of at least one non-elastic neckable material laminated to at least one non-elastic film defining a longitudinal and transverse dimension wherein the laminate is extensible and retractable in at least one dimension without significantly reducing the breathability and/or liquid barrier properties of the film layer. This laminate extensibility and retractability is the result of striated rugosities in, for instance, the longitudinal dimension of the film layer which enables the necked laminate to have an amount of extensibility and retractability in the transverse dimension. The laminate is made by first partially stretching the non-elastic film layer, attaching a non-elastic neckable layer to form a laminate and then stretching the laminate to neck the laminate and stretch the film to its desired fully stretched configuration.Type: GrantFiled: December 6, 1999Date of Patent: August 26, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Tod Morman, Robert John Schwartz, Howard Martin Welch, Patricia Hsiaoyin Hwang

Patent number: H2086Abstract: The present invention provides a filter media comprising (a) a nonwoven composite material comprising a stabilized mixture of thermoplastic microfibers and at least about 50%, by weight, of a secondary fibrous material such as pulp or polymeric staple fibers; (b) a first outer nonwoven web comprising a substantially uniform nonwoven web of autogenously bonded multicomponent fibers; and (c) a second outer nonwoven web wherein the nonwoven composite material is positioned between the first outer nonwoven web and second outer nonwoven web. The filter material is well suited to filtering liquid borne particulate matter ranging in size from 5&mgr; to about 25&mgr;.Type: GrantFiled: July 20, 1999Date of Patent: October 7, 2003Assignee: Kimberly-Clark WorldwideInventor: Nicole Michele Amsler
