Plastic container having at least a regional sharp-edged container geometry and process for producing the plastic container

Abstract

A plastic container manufactured from a preform with a mass share of at least 80% polyester and possibly an additive from the group consisting of dyes, fillers, catalysers, additives and lubricative additives. The plastic container comprises a container neck and a container shoulder which connects with the container neck and merges into a container body closed by a container base. The container shoulder, the container base and the container body are exclusively reshaped by a 2-stage stretch blow moulding method. The polyester is a copolyester and comprises groups which originate from the monomers cyclohexanedimethanol (CHDM) and/or monoethylene glycol (MEG), terephthalic acid (TPA) or its derivatives and isophthalic acid (IPA) or its derivatives. At least a part-region of the container body and/or of the container shoulder comprises a sharp edge with a radius of less than 0.5 mm. A method of manufacturing the plastic container is also described.
