Abstract: A mold for producing a stretch-blow molded polyester bottle from a preform comprises mold parts that can be shifted between an open position and a closed position. The mold comprises: first and second mold shell, within which, in the closed position, a bottle body can be molded; a holding stopper, which can be inserted into a bottle neck; a blow pin having a compressed-air intake for biaxial stretching of the preform; and a bottom part, which closes the two mold shells at the bottom side and is configured to mold the bottle bottom. A base is formed on the bottom part, which base projects into an interior of the mold and has a side wall with an inclination angle (α) of at most 5 degrees with respect to a vertical axis (35) of the mold and is oriented in parallel with the vertical axis.

Abstract: A mold body (10) for a blow mold (1). The mold body (10) has a bottom region (14), a shoulder region (13), a central region (15) and a separating plane (12). At least one mold cavity (11) has an inner wall (111) situated in the mold body (10). At least one temperature control channel (30) is arranged in the mold body (10). The at least one temperature control channel (30) is situated and/or positioned in the mold body (10) in such a way as to remove more heat from or supply more heat to a first region (112) of the inner wall (111) than a second region (113) of the inner wall (111) that is adjacent to the first region (112).

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.
