INPROVEMENTS RELATING TO CONTAINES FOR AND CONTAINING CARBONATED BEVERAGES

摘要

Containers for carbonated drinks are prepared from the sufficiently heated polyester plastic plates in molding die with a number of circular cross-section; ring-type section is cooled under thermo-forming temperature to form the separate circular container from hot plastic material; flange over the circular section is formed after thermo-forming of container; plastic forming flange is oriented radially and has small thickness by placing the brim of circular section with clearance from the molding chamber; and formed container is cut from the residual plastic plate along the circular line of the brim of flange.
