Abstract:
The invention relates to a method for producing a plastic container, in particular a plastic bottle, from a preform (3), wherein the preform (3) is heated in a heating device (2) and is subsequently stretch-blow-molded in a blow-molding device (1) to form the container (4).

Plain-Language Overview of Independent Claims

This patent has one independent claim. In simple terms, the core of the invention is a specific step in the process of making plastic bottles from preforms.

Independent Claim 1: This claim describes a method for making a plastic container, like a bottle, from a smaller plastic tube called a preform. The process involves heating the preform and then using a stretch-blow-molding machine to shape it into the final container. The key inventive step is that after the main heating of the preform and before it goes into the blow-molding machine, there is an additional, separate step of "tempering" (adjusting the temperature of) the neck region of the preform. This targeted temperature adjustment of the neck area is the central feature of the claimed invention.
