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 mold with two blow mold parts movable with respect to each other. The blow mold 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 mold along a pre-set conveying path, and a clean room inside which the blow mold may be conveyed during the expansion of the pre-forms. An inner wall of the blow mold 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.

1. An apparatus for the shaping of plastics material pre-forms into plastics material containers, the apparatus comprising:
at least one blow mould with at least two blow mould parts capable of being moved with respect to each other, the blow mould forming a cavity inside which the plastics material pre-forms are capable of being shaped into the plastics material containers, an inner wall of the blow mould facing the plastics material pre-form having an opening through which a first flowable medium is capable of being removed out of the cavity during the expansion procedure; a stressing device which acts upon the plastics material preforms with a second flowable medium for their expansion; a conveying device which conveys the blow mould along a preset conveying path; a clean room, inside which the blow mould is capable of being conveyed during the expansion of the plastics material pre-forms; and a flow connection between the opening and the clean room, said flow connection being sealed off from a non-sterile environment of the clean room.
