GLASS CONTAINER AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To form a thermoplastic resin thin-film layer in a sidewall part of a glass container so that a scratch in the sidewall part can be prevented from occurring during conveyance, etc., and a label can surely be applied with a paste. SOLUTION: This glass container 4 has a thermoplastic resin thin-film layer 1 distributed in the form of islands on the surface of a sidewall part 5 of the glass container 4. The thermoplastic resin thin-film layer 1 comprises plural islandlike parts 2 or the plural islandlike parts 2 and an aggregate 3 of the islandlike parts 2. The coverage on the surface of the sidewall part 5 is 3-60%. The maximum value of the maximum diameter dmax of the islandlike parts 2 and the maximum diameter Dmax of the aggregate 3 is 10-300μm. An aqueous dispersion of a thermoplastic resin having 0.05-1.0 wt.% of the content of the thermoplastic resin is formed into a spray 9 having 10-30μm average particle diameter in a cold end coating step after molding and sprayed on the sidewall part 5 once to three times to produce the glass container 4.
