Embodiment Construction

[0088] figure 1 A system 100 for sterilizing containers according to the internal prior art under the name of the applicant is shown. The conveying device 112 for conveying the plastic parison to the external sterilization unit 104 is first provided therein. Starting from this external sterilization unit 104, the plastic container is removed and guided to the internal sterilization unit 106. Finally, the plastic container is discharged again through the discharge unit 114. Thus, a total of two transfer units 112, 114 and another transfer unit are necessary between the two sterilization devices 104 and 106.

[0089] figure 2 A schematic diagram of the system 1 for sterilizing plastic preforms according to the present invention is shown. In this case, the plastic parison is first transferred to the transfer device 34 via the transfer opening 44. The conveying device 34 has a plurality of holding devices that hold the plastic parison, for example, on its outer circumference (for...

Abstract

The invention relates to a system for sterilizing plastic containers, especially plastic parisons (10), comprising: a conveying device (2), which conveys plastic parisons ( 10); the first sterilizing device (4), the first sterilizing device (4) is suitable for applying radiation to the outer surface of the plastic container to sterilize the outer surface; and the second sterilizing device (6), the second sterilizing device (6 ) is suitable for applying radiation to the inner surface of a plastic container in order to sterilize the inner surface. According to the invention, at least one holding device (8) is arranged on the conveying device (2) and at least one holding device (8) has an engaging element (82) which can be guided into the plastic container (10) In the region of the mouth for holding plastic containers (10), at least one component of the second sterilization device is integrated into the holding device.

Description

Technical field [0001] The invention relates to a system and method for sterilizing plastic containers, especially plastic parisons. It is known from the prior art that plastic containers or parisons are usually sterilized before they are filled. To perform this sterilization, several methods are known, such as, for example, sterilization by hydrogen peroxide. However, recently, attempts have been made to eliminate the use of such chemicals. Therefore, the transition that has occurred is to switch to performing sterilization by radiation, particularly but not exclusively by radiation with charge carriers such as electrons, for example. Background technique [0002] In the prior art, the plastic parison travels into a blow molding machine after heating or after a heating box. It is known from the internal prior art in the name of the applicant that after the heating box the plastic parison travels via the supply star wheel into the sterilization module, then is externally steri...
