Disclosed are a method and an apparatus for blow molding receptacles. A parison is shaped within a blow mold by applying blow pressure into the receptacle following a thermal conditioning process. The blow mold is mounted on a support. In the area of the blow mold, at least one molding element is placed in an interior enclosed by the blow mold in a closed state of the blowing station once the blowing process has started in such a way that a receptacle bubble created from the parison is deformed.
