Aseptic Blow Moulding Machine with Sterile Removal of Air

摘要

Apparatus for the shaping of plastics material pre-forms into containers includes at least one blow mould with two blow mould parts movable with respect to each other. The blow mould forms a cavity inside which the pre-forms may be shaped into the containers. The apparatus includes a stressing device which acts upon the pre-forms with a flowable medium for their expansion, a conveying device which conveys the blow mould along a pre-set conveying path, and a clean room inside which the blow mould may be conveyed during the expansion of the pre-forms. An inner wall of the blow mould facing the pre-form has at least one opening through which a flowable medium may be removed out of the cavity during the expansion procedure. A flow connection provided between the opening and the clean room is sealed off from a non-sterile environment of the clean room.
