Patent number: 6875497Abstract: A multilayer composite for applying printed graphics to a receptive substrate, comprising: a carrier sheet; a transparent breakcoat having an upper surface releasably bonded to the carrier sheet, and a lower print receptive surface on which graphics are permanently printed; and a layer of pressure sensitive adhesive having an upper surface permanently adhered to the thus printed graphics, and a lower surface releasably adhered to a protective liner. The protective liner is separable from the adhesive without disrupting the bond between the carrier sheet and the breakcoat, and the adhesive, and the adhesive is removably bondable to the substrate during a wet out period, after which the carrier sheet is separable from the breakcoat, allowing the breakcoat/graphics/adhesive residue to remain firmly bonded to the substrate.Type: GrantFiled: May 8, 2002Date of Patent: April 5, 2005Assignee: FLEXcon Company, Inc.Inventors: Philip R. Emery, Richard T. Skov

Patent number: 6872276Abstract: A process for transferring a thin polymeric film to either woven or non-woven fabrics by first coextruding the thin polymeric film with a plastic support layer, then adhesively laminating the polymeric film to a fabric, followed by delaminating the support layer. The thin base layer remaining on the fabric imparts desired properties to the fabric while maintaining the soft feel, or drapeability, of the fabric, as opposed to lamination of thicker polymeric films to fabrics.Type: GrantFiled: January 27, 2003Date of Patent: March 29, 2005Assignee: Honeywell International Inc.Inventors: Michael J.

Patent number: 6866926Abstract: A seal and method of manufacture is provided for sealing containers such as bottles, jars and the like. The seal (closure) can be formed with a lower sheetlike structure having a foam layer thereon. The lower structure can include foil and have a polymer layer, such as a PET layer thereunder A sealant layer can be provided under the bottom surface of the PET layer to bond the seal to a container opening. The polymer foam is advantageously polyethylene foam. Seals in accordance with preferred embodiments of the invention also include a top portion, which can be only partially bonded (directly or indirectly) to the bottom portion, so as to leave a tab portion extended therefrom. The top portion is advantageously bonded from periphery to periphery of the bottom portion and at or slightly offset from the diameter (middle) of the bottom portion. The top portion is advantageously formed with polymer material, such as an ethylene vinyl acetate (EVA) layer, having a layer of PET bonded on the top thereof.Type: GrantFiled: May 9, 2000Date of Patent: March 15, 2005Assignee: Illinois Tool Works Inc.Inventors: Joe Smelko, Marilyn Agnoluzzi

Patent number: 6841237Abstract: The invention provides an optical sheet having and sufficiently exhibiting high light transparency and uniform light diffusivity. The optical sheet comprises transparent resin layers 2 and 3 and a fine particle layer 5 consisting of transparent fine particles 4 which are arranged as a monoparticle layer between the transparent resin layers 2 and 3 in an embedded state, wherein the refractive indexes of said transparent resin layers are different from that of said transparent fine particle. The optical sheet is produced by a process which comprises at least a step of forming a transparent resin layer having at least temporary stickiness on a substrate, a step of forming a fine particle layer by covering said transparent resin layer with transparent fine particles so as to form a monoparticle layer and fixing them, and a step of laminating a transparent resin layer on said fine particle layer.Type: GrantFiled: April 4, 2002Date of Patent: January 11, 2005Assignee: Tomoegawa Paper Co., Ltd.Inventors: Makoto Murata, Kensaku Higashi

Patent number: RE38745Abstract: A laminate composition of a thin film of low density polyethylene adhered to a sheet of low density polyethylene foam by means of a very thin layer of low density polyethylene. The polyethylene foam has a low density which is preferably between about 1.9 pcf and about 2.2 pcf. The bottom polyethylene film serves as a vapor barrier. One side of the polyethylene film extends beyond one edge of the polyethylene foam sheet. The laminate composition is installed in a free floating manner on the concrete subflooring, with the polyethylene film or the polyethylene foam sheet contacting the surface of the concrete subflooring. The laminate composition is usually in long strips, so when it is installed one edge of one strip overlies the extended portion of the polyethylene film of an adjacent strip. Then the laminate wood finish flooring, in plank form, is installed on top of the laminate composition in a free floating manner. The laminate wood planks fit together in a tongue-in-groove manner and are glued together.Type: GrantFiled: September 14, 2001Date of Patent: June 21, 2005Assignee: Pactiv CorporationInventor: Stephen M.
