Embodiment Construction

[0036] Before explaining the detailed structure of the device for sterilizing the preforms ( 1 ) by using a plasma and before explaining the specific installation of the corresponding device into a blow molding machine, a description should first be made subsequently The principle structure of the blow molding machine.

[0037] The principle structure of the device for deforming a preform (1) into a container (2) is in figure 1 with figure 2 shown in .

[0038] The device for forming containers (2) basically comprises a blow molding station (3) provided with a blow mold (4) into which a preform (1) can be inserted. The preform ( 1 ) can be an injection molded part made of polyethylene terephthalate. In order to be able to insert the preform (1) into the blow mold (4) and to be able to remove the finished container (2), the blow mold (4) consists of mold halves (5, 6) and a bottom part (7 ), the bottom part can be positioned by a lifting device (8). The preform (1) can be...

Abstract

A method and a device for sterilizing preforms made of thermoplastic material intended for the manufacture of blow molded containers. The sterilization is performed by applying plasma. The sterilization device is provided with a plasma generator for this purpose. The sterilization is carried out on a transfer wheel after the preforms have been inserted into the blow molding station or on a transfer wheel. The plasma is generated outside the preform and introduced into said preform.

Description

technical field [0001] The invention relates to a method for sterilizing preforms made of thermoplastic material, which preforms are intended for the manufacture of blow-moulded containers. [0002] The invention furthermore relates to a device for blow molding containers which are sterile in at least one area, which has at least one blow molding station arranged on a support structure for molding thermoplastic preforms into containers. Background technique [0003] The production of sterile blow-molded containers typically takes place in such a way that the containers are sterilized using hydrogen peroxide or other chemicals after their blow molding and before their filling. It is also known to sterilize the preforms used as the starting product when blow molding the containers, in particular the region of the inner surface of these preforms. [0004] It is likewise known that a sterilizing effect occurs when the coating of the container is carried out with the application...
