Abstract
An apparatus for transforming plastic preforms into containers may include at least one blow mould which forms a cavity, inside which the plastic preforms can be transformed into containers. The apparatus may include a pressure application device for applying a medium to the plastic preforms in order to expand the preforms against an inner wall of the blow mould delimiting the cavity. The apparatus may include a stretching rod for stretching the plastic preforms in the longitudinal direction. The apparatus may include a cleaning device for cleaning regions of the blow mould. The cleaning device may include at least one outlet opening for a cleaning medium for cleaning the blow mould, and this outlet opening is arranged at least at times inside the blow mould.
Claims23
Apparatus for transforming plastic preforms into containers, comprising:
- at least one blow mould which forms a cavity inside which said plastic preforms can be transformed into containers;
- a pressure application device for applying a medium to the plastic preforms in order to expand said plastic performs against an inner wall of the blow mould delimiting the cavity;
- a stretching rod for stretching the plastic preforms in a longitudinal direction thereof, the stretching rod having an end section pointing towards a bottom of the containers;
- and
- a cleaning or sterilization device for cleaning or sterilizing at least one region of the blow mould, the cleaning device including at least one outlet opening for a cleaning or sterilizing medium for cleaning or sterilizing the blow mould, said at least one outlet opening including an outlet opening arranged in said end section of the stretching rod and at least at times inside the blow mould.
Apparatus for transforming plastic preforms into containers, comprising:
- at least one blow mould movable between an open configuration and a closed configuration, an inner wall of said blow mould delimiting a cavity which plastic preforms can be transformed into containers;
- a pressure application device configured to apply a medium to the plastic preforms in order to expand said plastic performs against the inner wall of the blow mould;
- a stretching rod configured to stretch the plastic preforms in a longitudinal direction thereof, the stretching rod having an end section pointing towards a bottom of the containers;
- and
- a sterilizing device structured and arranged to sterilize regions of the blow mould, the sterilizing device including at least one outlet opening for directing a sterilizing medium toward at least one region of the blow mould for sterilizing said region, said at least one outlet opening being arranged at least at times inside the blow mould, said at least one outlet opening being arranged in the pressure application device.
