The invention relates to a preform for producing containers, in particular PET bottles, by means of stretch blow molding, comprising a substantially hollow-cylinder-shaped wall part having a hollow cylinder axis and having a substantially constant wall thickness WTS and comprising a bottom part, which is connected to the wall part and which closes an opening of the hollow-cylinder-shaped part, wherein the bottom part has a substantially conical section and a gate mark, which is arranged on the hollow cylinder axis and which has the diameter A. According to the invention a first connection section having a curved outer wall is provided between the conical section and the gate in order to specify a preform that is easy to produce by means of the injection molding method, i.e., has good injection behavior, and at the same time has advantages in stretch blow molding. |
