PLASTIC BOTTLE

摘要

PURPOSE:To obtain a plastic bottle which increases the fitting srength of the bottle body to the parts like the grip. CONSTITUTION:A hardly crystalline copolymerized polyester resin is forced to be contained in either one or both of a bottle body 1 and the parts thereof. For instance, the bottle body 1 is formed by blow-molding chiefly with dicarboxylic acid composed of terephtalic acid 60-99mol% and isophtalic acid 1-40mol% and copolyester resin made by esterification with ethylene glycol. And a grip 2 having copolyester or polyethylene terephthalate is stuck on the bottle body as an integrated body by heat-melting.
