disinfect the already molded cup or breaker like containers 3 has a cooling element 20 with recesses 21 whose shape is like the external shape of the containers 3 so that a container 3 inserted into the recess rests with its outer wall against the wall of the recess 21 the cooling element 20 preferably has the same shape as the matrix 13 of the molding device 12 for purposes of loading and unloading the cooling element 20 can be raised and lowered on a rod 22 to which it is secured the cooling element 20 is pierced by a plurality of channels 35 only one of which is shown which are connected to a coolant inflow line 36 and a coolant outflow line 37 as best shown in fig2 several suction bores 33 also discharge into the recesses 21 of the cooling element 20 and communicate via collection bores 34 with a suction line 19 with the interposed film strip 1 having the molded containers 3 the cooling element 20 rests in the operating position against a stationary headpiece 23 which represents a cover for the containers 3 inserted into the recesses 21 of the cooling element 20 the headpiece 23 has a recess 24 on its underside to provide clearance and also has two openings 25 directed into the recesses 21 a line 27 leading to a valve 26 is connected to these openings 25 connecting lines 28 29 30 which lead to a steam generator 38 a sterile air source 39 and a suction pump 40 also lead to the valve 26 another line 31 connects the recess 24 of the headpiece to the valve 26 for ventilating air.
