Problems solved by technology

In fact, prolonged exposure of objects to electronic radiation is likely to have adverse effects on the object, namely discoloration, deterioration, cross-linking phenomena or odor migration
However, prior art solutions only partially limit these problems

Embodiment Construction

[0034] figure 1 System 1 is shown, which has an electron gun that produces a high intensity stream of electrons. Advantageously, the electron flow generated at the outlet of the electron gun is a pulsed electron flow / beam for bombarding the container cap 2 and / or the neck to decontaminate the container cap and / or the neck. Different embodiments are described here which are suitable for the cap 2 , but it is obvious that these embodiments are also fully suitable for the aforementioned container necks. The covers 2 are advanced by means of a transport device 3 into a sterilization chamber 4 with a pulsed electron gun, ie a closed sterile chamber. Forwarding here refers to continuous delivery in time. According to another embodiment, the cover 2 is positioned in the sterilization chamber 4 sequentially, ie step by step, for example by means of the conveying device 3 . The use of all these elements is detailed below.

Abstract

The invention relates to a method for decontaminating caps (2) or necks of containers by electron bombardment, said method comprising: an operation of the passage or positioning of the caps (2) or necks of containers in front of an electron bombardment window (8), the opening of the caps (2) or necks of the containers facing said window (8); and an operation of electron bombardment of said caps (2) or necks of the containers, during the passage or positioning of the caps or necks of the containers in front of the window (8); the bombardment being carried out by means of a pulsed electric field comprising a series of electrical pulses of determined frequency, duration and intensity.

Description

technical field [0001] The invention relates to the field of lids or necks of sterile containers. [0002] In particular, the present invention relates to a method and system for decontaminating the caps or necks of containers, allowing optimal treatment of all surfaces of these caps or necks. Background technique [0003] Containers such as tubes, jars, bottles, cardboard food packages or PET (polyethylene terephthalate) plastic bottles are often used to hold liquid consumer products such as beverages, pharmaceuticals or cosmetics. Containers such as bottles, especially bottles made of PET, are usually produced by stretch blow molding from blanks, such as preforms or intermediate containers, which have previously undergone primary forming operations. The blanks and container closures are initially stored in a non-sterile environment. [0004] The cardboard food packaging box itself has a closure consisting of a built-in neck closed by a lid. The manufacture of the pack g...
