Patent number: 6159423Abstract: Disclosed herein is a single step sterilization wrapping material suitable for use, as an example, in wrapping surgical instruments and supplies for sterilization, transportation and storage. The material includes separate inner and outer wraps which, unlike previous wraps, are joined to one another. Common wrapping techniques involve wrapping items to be sterilized with two separate sheets of wrap. The present invention provides separate wraps which can be specially engineered to deliver specific properties for each sheet and then joined to one another so as to permit wrapping and opening in a neat single step process which increases efficiency and saves time and money. In special situations the outer wrap can be engineered with increased strength, the inner wrap with increased barrier properties and the inner and outer wraps can be made visually distinct from one another so that improper wrapping or opening, is not a problem.Type: GrantFiled: June 1, 1999Date of Patent: December 12, 2000Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Sonya Nicholson Bourne, Nelson McRay, Lavada Campbell Boggs, William Ralph Neff, Charles John Morell, Marsha Lottie Vaughn

Patent number: 5869154Abstract: Metal sparkles having one or more colors dispersed throughout a translucent resin at a concentration which eliminates the appearance of scratches and scuff marks on the resin surface. A pigment may be used in the translucent resin to yield a variety of decorative colors to create matching containers and utensils. The metal sparkle concentration in the translucent resin contains on an average 11/2%-3% metal sparkles by weight and 0.25%-1% color by weight. The sparkle concentration may be used at a letdown ratio of 4% resulting in a composition having an average of 0.06%-0.12% sparkles by weight and 0.01%-0.04% color by weight. The sparkles are random cuts of multi-colored aluminum having an average size of 1/64" (0.015) and are manufactured from the thinnest standard sheets of aluminum which are polished to a mirror-like surface of brilliant reflectivity.Type: GrantFiled: March 21, 1996Date of Patent: February 9, 1999Assignee: Fort James CorporationInventor: Julie M.

Patent number: 5858521Abstract: The vibration damper material comprises a laminate of a viscoelastic layer and a hardenable pressure sensitive adhesive layer, and a release liner applied onto the hardenable pressure sensitive adhesive layer. The viscoelastic layer is intended to form a vibration damping layer, and contains a viscoelastic material mainly comprised of unvulcanized rubber to which a vulcanizing agent (crosslinking agent) has been added. The hardenable pressure sensitive adhesive layer comprises a hardenable pressure sensitive adhesive which has adhesive properties in the uncured state but has a strong adhesive strength when it is cured by heating, irradiation with light or by being blocked from air for example. This hardenable pressure sensitive adhesive layer contains a sticking polymer, a reactive oligomer and a polymerization initiator. The release liner which is utilized has a silicone layer formed on the surface of a base material thereof.Type: GrantFiled: June 7, 1995Date of Patent: January 12, 1999Assignee: Lintec CorporationInventors: Takuya Okuda, Toshio Sugizaki, Masao Kogure, Takanori Saitoh
