An apparatus for producing at least one container, in particular in ampoule form, made of thermoplastic material, comprising a mould (13) with mould components (15, 17) and with a first calibrating mandrel (19) and a second calibrating mandrel (23), which can move coaxially in relation to the longitudinal direction (21) of the container (1) and in relation to one another, wherein the first calibrating mandrel (19) and the second calibrating mandrel (23) can move in relation to one another, the first calibrating mandrel (19) through the container (1) located in the mould (13) and the second calibrating mandrel (23) from the outer side of the container (1), into a shaping position in which they calibrate a bottom area which forms at least part of a container bottom between the mandrel ends thereof, and comprising a severing device, which has a movable cutting or punching surface (37), in order to sever excess plastic material which forms during the shaping process in interaction with a cutting or bearing edge on the mould components (17) assigned to the bottom region, is characterized in that the severing device has a cutting device (35), which is guided in an axially displaceable manner on the second calibrating mandrel (23), forms the cutting or punching surface (37) and can move between the withdrawn position and the punching position independently of the movement of the respective calibrating mandrel (23).
