Embodiment Construction

[0060] figure 1 A schematic illustration of an apparatus for producing plastic containers is shown. The device 50 has a heater 30 in which the plastic parison 10 is heated. In this case, the plastic parisons 10 are guided through the heater (such as in this case an endless chain) 30 by means of a conveying device 34 and are heated in this case by heating elements 31 . Adjacent to this heater 30 is a transfer unit 36 ​​which transfers the plastic parisons 10 to the sterilization unit 32 . In this case, the disinfection unit 32 also has a transfer wheel 37 and the disinfection unit can be arranged on this transfer wheel 37 or can also be fixed. In this area, disinfection can take place, for example, by hydrogen peroxide or also by electromagnetic or UV radiation. In particular, internal sterilization of the parisons is carried out in this area. Disinfection in this region of the heater 30 or before the heater 30 is also conceivable.

Abstract

A system (1) for transforming plastic parisons (10) into plastic containers (10a) with a clean room (20), with at least one blow station (8) comprising a blow mold for shaping the plastic parisons (10) by means of at least one process pressure (p1, p2, pi) and with a venting device (3) for venting the process pressure, or a process pressure reduced to recovery pressure (R), into the atmosphere (U), in which the venting device (3) comprises at least one gas pressure changing device (4). According to the invention the gas pressure changing device (4) can adjust and maintain a pressure difference between the clean room (2) and the venting device (3).

Description

technical field [0001] The present invention relates to a system and method for forming plastic parisons into plastic containers using a clean room, the system having at least one blow molding station comprising blow molds for passing through at least one a process pressure to form a plastic parison; and a venting device for venting said process pressure, or a process pressure reduced to a recovery pressure, to atmosphere, wherein the venting device includes at least one air pressure changing device. Background technique [0002] General systems and methods for molding plastic parisons into plastic containers in which the processing of the plastic containers takes place under sterile conditions are known from the prior art. [0003] For example, international patent application WO 2010 / 020529 A2 describes a system for molding plastic parisons into plastic containers, the system having a transfer device comprising a plurality of blow molding stations and a clean room. With t...
