Abstract
Abstract A collapsible dispensing container having a laminated tubular body, the laminated tubular body including a metal foil lamination, a layer of a polyolefin on the outside of the metal foil lamination, and, on the inside of the metal foil lamination and on the outside of the polyolefin layer, a layer of a copolymer resulting from the polymerization of 100 parts by weight of (a) at least 50 percent by weight of at least one nitrile having the structure ##STR1## wherein R is hydrogen, a lower alkyl group having from 1 to 4 carbon atoms, or a halogen, and (b) up to 50 percent by weight based on the combined weight of (a) and (b) of an ester having the structure ##STR2## wherein R 1 is hydrogen, an alkyl group having from 1 to 4 carbon atoms or a halogen, and R 2 is an alkyl group having from 1 to 6 carbon atoms, in the presence of from 1 to 40 parts by weight of (c) a copolymer of a conjugated diene monomer selected from the group consisting of butadiene and isoprene and an olefinically unsaturated nitrile having the structure ##STR3## wherein R has the foregoing designation containing from 50 to 95 percent by weight of polymerized conjugated diene and from 50 to 5 percent by weight of polymerized olefinically unsaturated nitrile.
