Title:
【発明の名称】高温の液体を充填するためのポリエチレンテレフタレート製容器の製造方法
Document Type and Number:
Japanese Patent JPH072371
Kind Code:
B2
Abstract:
In the process according to the invention a container is moulded by blow-drawing starting with a polyethylene terephthalate (PET) preform.
Only the body of the preform is heated to a temperature at which a lengthwise drawing and a transverse drawing do not induce any stress in the material forming the container. The preform is then transferred into a mould whose walls are heated and maintained at a temperature below that of the body of the preforms, where it is drawn lengthwise and blown. The biaxial drawing ratio used for changing from the preform to the container is between 7 and 9.
