A device for forming plastic parisons into plastic containers includes at least one forming station arranged on a conveying device and configured to form plastic parisons into plastic containers by applying a gaseous medium, the forming station includes an application device configured to apply the flowable medium to the plastic parisons, and includes a pressure supply device and/or is in fluidic connection with a pressure supply device configured to provide the flowable medium at a prespecified pressure, wherein pressure provided by the pressure supply device is greater than pressure required and/or used for the application to the plastic parisons, wherein the device includes at least one valve device which controls application to the plastic parisons, which valve device is configured to interrupt the supply of air into the container when the pressure of the flowable medium within the container has reached a prespecified pressure level.

The invention relates to a method and an plant for the production and treatment of sterile plastic containers, in which preforms made of a thermoplastic material are heated in the region of a heating section and then formed into containers by pneumatic or hydraulic pressure, and wherein the preforms or the containers or both are sterilized and pass through at least one low-germ zone which is surrounded by an enclosure, characterized in that the enclosure 2, 2′ has an outer housing 3, 3′ and an airlock chamber 4, 4′ through which treatment medium is extracted from the low-germ zone 1, 1′ and at the same time air is extracted from the outer environment of the outer housing 3, 3′.

The invention relates to a method in which a polyester melt containing one or more polyesters is produced, the polyester melt being foamed by a blowing agent and a foamed granulate is produced from the foamed polyester melt. The intrinsic viscosity (IV) of the polyester melt is reduced by the blowing agent about at least 0.05 dl/g, measured according to ASTM D4603, and the IV of the foamed granulate is then increased by means of a solid phase polycondensation (SSP).

A plastic molding method comprises moving each part of a plurality of parts along a selected one of a plurality of possible paths through dispensing and molding stations of a molding system. A controller tracks an operating state of each station, selects process stations capable of receiving a part for processing; identifies parts capable of processing at the selected process stations, and assigns individual parts to individual process stations.

Even when the filling rate is high, the surface temperature of molded bottles is kept at a certain temperature or higher, and the bottles can be adequately sterilized with a sterilizer.

A preform is heated, the heated preform is sealed in a neck portion mold, a trunk portion mold and a bottom portion mold at a predetermined temperature range, and the preform sealed in the molds is blow-molded into a bottle. Any bottle is removed which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of any of which is outside the predetermined temperature range, and a sterilizer is blasted to any bottle for sterilization which has been molded in the neck portion mold, the trunk portion mold and the bottom portion mold the temperature of all of which is in the predetermined temperature range.

The present invention relates to an installation for manufacturing containers made of thermoplastic material, having a sterilizing mode and a production mode. The installation comprising a molding machine, a transfer means, and a decontamination device. The molding machine is equipped with at least one molding device having stretching means, and the molding device is designed to manufacture by stretch blow molding said containers from preforms when the installation is in production mode. The transfer means conveys the manufactured containers between the molding machine and a second downstream machine when the installation is in production mode. The decontamination device introduces the sterilizing agent into at least one sterilizing preform during the sterilizing mode. The installation further comprises removal means that can be actuated in sterilizing mode to remove the hollow bodies from the transfer means upstream from the second machine.

The present invention relates to a method for sterilizing stretching means (12) of a container moulding device (10) fitted to a plant for manufacturing thermoplastic containers obtained by stretch-blow-moulding from production preforms, the said method for sterilizing the stretching means (12) comprises at least the steps consisting in: —introducing a determined quantity of a sterilizing agent into a sterilization preform (30), —during a step referred to as a conversion step, converting said sterilization preform (30) into a hollow body (50) by stretching—blowing into the said moulding device (10), said introduction of the sterilizing agent being performed in the vapour state in a sterilization preform (30) at a temperature that allows a uniform film of mist to be deposited by condensation onto an internal surface (32) of said sterilization preform (30), and in that at least two sterilization preforms (30) are then converted successively into hollow bodies (50) in the one same moulding device (10).
