Publication number: 20150232241Abstract: A multi-layer control device or one-way valve (100) includes: a first layer (10) having at least one first opening (12) formed therein; and a second layer (20). The first and second layers are joined together such that at least one channel (24) is defined therebetween, which channel selectively permits gas flow from the first opening out of the device/valve. In operation, the valve selectively opens to permit gas flow through the channel in response to a pressure differential on opposing sides of the valve, wherein the pressure differential sufficient to open the valve (?Po) dynamically varies over time. Suitably, a material is arranged in the channel which experiences a change that precipitates the dynamic variation of ?Po.Type: ApplicationFiled: October 3, 2013Publication date: August 20, 2015Inventors: David R. Gardner, Sarang Bhawalkar, William G. Hartman, Anne Shim

Publication number: 20040142495Abstract: An article for detecting the presence, or the absence, of an analyte. The analyte is indicative of a change in the status of a packaged material. The article generally includes a facestock film having first and second surfaces, an adhesive layer adjacent to the facestock film, and a detecting system adjacent to the facestock film. A measurable analyte can be in vapor and/or liquid form, and the detecting system indicates whether the analyte is present. That is, the detecting system responds to contact with the analyte by indicating that such contact has occurred, or that the analyte is present.Type: ApplicationFiled: December 16, 2003Publication date: July 22, 2004Inventors: William G.

Patent number: 5629087Abstract: A method of adhesively securing first and second members together by sliding movement of the members along an interface where the members are to be joined by an adhesive layer having opposed normally tacky and normally sliding-movement-resistant sides includes the step of applying a liquid to an exposed side of the adhesive side to reduce its tackiness. After sliding assembly of the members, the liquid is transmitted from the side of the adhesive to the interior of the adhesive to enable tack increase at the exposed adhesive side and adhering of the members together. The adhesive includes a moisture absorbing component to enable liquid accumulation at the exposed side and subsequent transmission to the adhesive interior.Type: GrantFiled: April 24, 1995Date of Patent: May 13, 1997Assignee: Avery Dennison CorporationInventors: William G.
