Patent number: 6120860Abstract: Multilayer film structures and packages therefrom which are particularly suited for containing organics such as organic liquids or solvents, e.g., amines, diamines, triamines, xylenes, tolene, ethoxyethanols, urethanes, or epoxies, or the like, or materials containing organics are disclosed as are methods for containing such organics. The film structures have two layer elements. The first layer element has a flexible barrier material layer and a sealant layer; the second layer element has a high barrier material layer; and when formed into a package such as a pouch the sealant layer is disposed interiorly and is used to seal the package together. Suitable materials for the high barrier material include metal foil, e.g., aluminum foil, and nylon coated on at least one side with a polyvinylidene chloride copolymer; the flexible barrier material layer is suitably nylon; and, the sealant is preferably ethylene vinyl acetate.Type: GrantFiled: November 25, 1996Date of Patent: September 19, 2000Assignee: American National Can CompanyInventors: William E.

Patent number: 4777085Abstract: The invention is in an improved multiple layer packaging sheet material which can be formed into closed and sealed packages suitable for holding products containing substantial fractions of cyanoacrylate. The invention depends on the positioning of high density polyethylene in direct contact with the cyanoacrylate-type product, and positioning a primer on the other side of the high density polyethylene. Preferred embodiments of the sheet structure include additional layers to provide barrier and abuse resistance properties, and the necessary adhesive materials to hold the various layers of the structure together with good adhesion. Additional layers are contemplated. The sheet structure can be formed into a package which positions the high density polyethylene adjacent the cyanoacrylate product, and between it and the other layers at all locations of contact between the cyanoacrylate product and the packaging sheet material.Type: GrantFiled: December 28, 1984Date of Patent: October 11, 1988Assignee: American National Can CompanyInventors: Lee J. Murray, Jr., Suzanne E. Schaefer

Patent number: 4155895Abstract: An ink composition is provided which is suitable for use on bare metal, for example, tinplate or aluminum as well as on such metals having organic coatings applied to surfaces thereof. The compositions may also be used on plastic containers or retortable pouches comprising plastic or plastic-metal foil laminates. The inks are suitable for use in contact printers or in jet ink printing techniques. The ink compositions are thermotropic, i.e. they change color in the presence of steam at elevated temperature and are useful as sterilization indicators. The inks comprise essentially a binder resin component, an alcohol solvent and a colorant which reacts in the presence of steam at elevated temperature to produce a visible and permanent color change.Type: GrantFiled: May 30, 1978Date of Patent: May 22, 1979Assignee: American Can CompanyInventors: Stanley E.
