Patent number: 7704602Abstract: An iodine/iodide-containing hot melt coatable adhesive is provided. This adhesive is prepared by mixing iodine and an iodide salt, individually or in combination, with solubilizing liquids. The iodine and iodide salt are combined with a pre-adhesive composition in a hot melt mixer, with an iodine/iodide complexing agent being present in the mixture. The mixture is mixed at a temperature from about 130° C. to about 200° C. and sufficiently to form an iodine/iodide-containing hot melt coatable adhesive. Alternatively, the iodide may be generated in situ. The adhesive so prepared may be packaged for coating on a substrate at a later time, or may be immediately coated to form an adhesive composite. Adhesive composites, particularly surgical incise drapes, are provided incorporating this hot melt coatable adhesive.Type: GrantFiled: February 8, 2007Date of Patent: April 27, 2010Assignee: 3M Innovative Properties CompanyInventors: Danli Wang, Stephen E. Krampe, Zhiming Zhou, Matthew T. Scholz, Michael P. Daniels

Publication number: 20030015819Abstract: An elastic web of material has a multiplicity of stems extending from at least one side of the web. The web includes a first continuous layer of elastic material having a first side and a second side and a second layer of material. The second layer of material has a first side which faces the first side of the first layer and a second side from which the stems extend. The first and second layers of material are joined together. The second layer of material can be formed of thermoplastic material or melt processable polymeric material. The first and second layers of material are melt formed. They are joined by coextrusion or lamination to form a multiple layer sheet on which a multiplicity of stems are formed on at least the second layer by a process such as embossing the stems into the heated web using a patterned roll or mold.Type: ApplicationFiled: September 9, 2002Publication date: January 23, 2003Applicant: 3M Innovative Properties CompanyInventors: Leon Levitt, Robert D. Kampfer, Michael D. Delmore, Stephen E. Krampe, Brandon T. Berg, Alan J. Sipinen, Mark E. Napierala, Victor P. Thalacker

Patent number: 6436499Abstract: The present invention is directed to a cold seal package that includes constructions wherein two substrates, or two portions of one substrate, are sealingly engaged to one another using a substantially natural latex rubber-free contact adhesive. The two substrates can be easily peeled apart without substantial damage to the substrates. Furthermore, the substrates cannot typically be resealed, or refastened, once peeled apart. That is, the cold seal formed by the adhesive between the substrates is substantially non-refastenable. Advantageously, a cold seal package of the present invention is particularly well suited for aseptic delivery of packaged goods, such as bandages, dressings, and the like.Type: GrantFiled: March 2, 2000Date of Patent: August 20, 2002Assignee: 3M Innovative Properties CompanyInventors: Stephen E.
