Patent number: 7108765Abstract: An insulating paperboard contains at least one layer of cellulose fibers. The one layer is at least partially composed of bulky fibers. The paperboard is sufficiently insulated to provide a hot water ?T across the paperboard of at least 0.7° C.±2.3° C. per 0.1 mm of caliper. The paperboard may be embossed to decrease surface transmission of heat. A hot cup may be produced from the insulating paperboard.Type: GrantFiled: May 14, 2004Date of Patent: September 19, 2006Assignee: Weyerhaeuser CompanyInventor: Donald D. Halabisky

Patent number: 6627249Abstract: The blood absorbence properties, e.g., free swell blood absorbence capacity and after load blood absorbence capacity of superabsorbent materials is enhanced by combining the superabsorbent materials with enhancing agents which serve to enhance the blood absorbent properties thereof. The enhancing agents in amounts ranging from about 0.01-8 weight percent is applied to the superabsorbent materials or they can be provided on a fibrous material to be combined with the superabsorbent materials. The enhancing agents are selected from materials that include functionalities that allow them to hydrogen bond to the superabsorbent material when the enhancing agent is applied directly thereto or combined with materials to which the enhancing agents have been applied.Type: GrantFiled: March 18, 2002Date of Patent: September 30, 2003Assignee: Weyerhaeuser CompanyInventors: Michael R. Hansen, Donald D. Halabisky

Patent number: 5837627Abstract: A web of fibers is bound together by a bonding medium that has been activated by partially solubilizing the bonding medium with a solvent therefor. The fibers are insoluble in the bonding medium. As the bonding medium is partially solubilized, it becomes tacky and flows into contact with the fibers and with itself Thereafter, the solvent is absorbed by the bonding medium, allowing the bonding medium to resolidify and bond the fibers in a matrix, increasing the web strength.Type: GrantFiled: January 13, 1997Date of Patent: November 17, 1998Assignee: Weyerhaeuser CompanyInventors: Donald D. Halabisky, Hugh West, Andre S. Hajnal, Terry M. Grant

Patent number: 5432000Abstract: A fiber product comprises dry discontinuous fibers having a starch binder on at least a portion of the fiber surfaces, at least about seventy percent of the starch binder coated fibers being unbonded to one another, solid particles are adhered to the fibers by the binder without the binder entirely coating the particles. The fibers may be air laid into a web or formed into an absorbent structure. Superabsorbent particles are a specific example of the particles which may be adhered to the fibers.Type: GrantFiled: March 22, 1991Date of Patent: July 11, 1995Assignee: Weyerhaeuser CompanyInventors: Richard H. Young, Sr., Amar N. Neogi, Michael R. Hansen, Kevin T. Hodgson, Donald D. Halabisky, David G. Marsh, Christel Brunnenkant, David W. Park, Paul G. Gaddis, William C. Johnston, Jr.

Patent number: 4690835Abstract: A process of reinforcing a polyethylene coated blank in which a reinforcing stripe is applied to a polyethylene coated web along a longitudinal score line which is to be scored. The web is thereafter scored along the line and the blank is cut from the web. The reinforcing stripe has a major portion of polyethylene, a small amount of vinyl acetate and a polypropylene/polyisobutylene copolymer. During the application, the stripe material has a viscosity of 18,000-26,000 centipoise.Type: GrantFiled: February 3, 1986Date of Patent: September 1, 1987Assignee: Weyerhaeuser CompanyInventors: Donald D. Halabisky, Dwight A. Dudley, II

Patent number: 4586643Abstract: A reinforced blank for liquids and a method of producing said blank. The score lines which hinge the bottom closure panels to the side walls is reinforced. The container has a polyethylene coating and the reinforcing material must be compatable with the polyethylene coating. It must be able to stick to the polyethylene. It must be able to be processed and placed on the polyethylene within the existing process. It must have a quick cure time, around a half second, and it must be nonflammable because of the flame sealers used to later form the container. It must be easy to apply at speeds of about 600 feet a minute and it must be a resin that does not activate. The resins applicable have viscosities from 18,000 to 26,000 centipoises and have from 65-85% polyethylene, a small amount of vinyl acetate as either polyvinyl acetate or ethyl vinyl acetate and the remainder a polypropylene/polyisobutylene copolymer.Type: GrantFiled: June 1, 1984Date of Patent: May 6, 1986Assignee: Weyerhaeuser CompanyInventors: Donald D. Halabisky, Dwight A. Dudley, II
