Thus, while this type of processing head can be inserted through most container apertures, it cannot be inserted into these conventional preforms because of the reduced inner diameter of conventional preforms as viewed from the aperture relative to the distal end. middle

Embodiment Construction

[0056] figure 1 is a sterilization device 1 or electron beam emitter 1 known in the prior art for sterilizing containers with an electron beam 2 , as well as an embodiment of a preform 3 and a basic design of the electron beam 2 impinging on this preform 3 .

[0057] The illustrated embodiment of the preform 3 has a diameter D3a or inner diameter D3a correspondingly in the aperture area 3a which is larger than the corresponding diameter D3b or inner diameter of the lower area 3b D3b, so that, as already explained above, a complete sterilization of at least the lower extent 3b of the preform 3 will take place using the radiation fingers known from the known prior art.

[0058] Without suitable equipment, such as reflector equipment, the electron beam 2 emitted by the electron beam emitter 1 can only emerge from the exit window 1 a in a non-directional manner and finally reach the inner region of the preform 3 partially I or the inner space I, or not at all into the inner regio...

Abstract

The invention relates to a device and method for sterilization of the internal walls of containers with a reflector device for e-beam. The apparatus and the method of sterilizing inner walls of containers, wherein the apparatus has at least one electron beam emitter with at least one electron beam accelerator and an outlet window for the electron beams, a conveying device for conveying the containers to be sterilized and a reciprocating device for permitting a relative movement between the containers and the outlet window in a longitudinal direction of the containers. A reflector apparatus is connected to the electron beam emitter in a positively locking and / or friction locking manner at least locally in a region of the outlet window and is capable of being introduced at least locally during a defined period of time into an interior space of the container to be sterilized, in order to apply the electron beams to the inner walls of the container.

Description

technical field [0001] The invention relates to a device and a method for sterilizing the inner walls of containers using at least one electron beam emitter according to the preambles of claims 1 and 8 . Background technique [0002] The equipment for sterilization of containers is incorporated, for example, in the production and filling machinery of manufacturers of containers and bottles, preferably allowing the sterilization of the interior spaces of the containers which come into contact with the medium received in the containers. [0003] In this case different methods can be used to sterilize the containers. In this way, for example, a liquid or flowing sterilizing agent (chemical sterilizing) can be applied to the inner wall of the container, or the container can be immersed in an agent of this type. In this case, however, the container usually has to be rinsed and dried after sterilization in order to prevent negative interactions between the sterilizing agent and t...
