Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
140 words
An article of manufacture comprising a glass bottle having its outer surface coated with a continuous layer amount of a random ethylene copolymer having a melt index of about 60 to about 120 decigrams per minute when measured under a pressure of 44 psi at a temperature of 190° C. in accordance with ASTM D-1238, containing copolymerized therein: (a) about 0.05 to about 4 mole percent of an acrylic ester moiety having the formula: ##STR5## (b) about 0.01 to about 1 mole percent of an acrylic acid moiety having the formula: ##STR6## (c) about 2 to about 8 mole percent of an amide moiety having the formula: ##STR7## wherein R is hydrogen or methyl and each of R 1 and R 2 is an alkyl group having one to four carbon atoms and the remainder consisting essentially of ethylene moieties.
Claim 2
Dependent Claim
140 words
