Abstract

An apparatus for forming plastic preforms into plastic containers, with a movable carrier on which at least one forming station is arranged for forming the plastic preforms, wherein the forming station is transported along a predefined transport path, and wherein the apparatus has a clean room inside which the plastic preforms are formed, wherein this clean room is isolated from a non-sterile environment by at least one wall, with a sterilisation device for sterilising the plastic preforms and/or plastic containers, which device acts upon the plastic preforms and/or plastic containers to be sterilised with a flowable sterilisation medium for their sterilisation. According to the invention, the apparatus comprises an ejection device for ejecting containers from the clean room, and this ejection device has a lock chamber from which the ejected containers can be removed, wherein this lock chamber can be acted upon with an atmosphere containing a sterilisation medium.
