PLASTIC CONTAINER HAVING AT LEAST A REGIONAL SHARP-EDGED CONTAINER GEOMETRY AND PROCESS FOR PRODUCING THE PLASTIC CONTAINER

机译:塑料容器至少具有区域锋利的容器几何形状和制造塑料容器的方法

摘要

A plastic container is described, manufactured from a preform having a mass fraction of at least 80% polyester and optionally at least one additive from the group consisting of dyes, fillers, catalysts, additives and lubricating additives. The plastic container comprises a container neck and a container shoulder adjoining the container neck which merges into a container body sealed with a container bottom. The container shoulder, the container bottom and the container body are formed exclusively by means of a blow molding process in a 2-stage stretch blow molding process. The polyester is a copolyester and comprises groups which derive from the monomers cyclohexanedimethanol (CHDM) and/or monoethylene glycol (MEG), terephthalic acid (TPA) or derivatives thereof and isophthalic acid (IPA) or derivatives thereof. At least one subregion of the container body and/or the container shoulder has a sharp edge with a radius of less than 0.5 mm. A process for producing the plastic container is also described.
