Abstract

A method for producing a blow molded plastic bottle starting from a preform comprises providing a preform with a specific wall thickness distribution and a blow mold are provided, the cavity of the mold having at least one channel at the locations of the plastic bottle that are to be strengthened. Subsequently, the preform is heated in such a way that the portion of the preform that correlates with the channel of the cavity is thinned to a lesser extent during the stretching and/or blow, and an accumulation of plastics material is brought about in the channel during the main blow molding operation. A plastic container produced by this process has strengthening elements formed as at least one outwardly protruding bead of material and have a wall thickness that is at least 30%, greater than the wall thickness of a portion of the wall adjacent to the bead of material.
