HEAT-RESISTANT CONTAINER

摘要

PURPOSE:To obtain a heat-resisting container that is equipped with a cylindrical holding part and is formed in a shape allowing an in-molding mold inserted on occasion of forming between a cylindrical trunk part and the cylindrical holding part to be extracted, and is available for being sealed up easily over its opening and is furthermore available for being stacked in tiers for putting in a filling machine. CONSTITUTION:Vertical pleats 11 are formed in corrugated shape on the circumference of a cylindrical holding part 10 so that the pleats can project and recede in an arc shape alternately in the radial direction, and the cylindrical holding part 10 is formed so that it can be enlarged on occasion of forming. The cylindrical holding part is also formed so that the lower part thereof is normally formed in small diameter.
