Embodiment Construction
[0064] figure 1 The device 1 according to the invention is shown in a first embodiment. In this case, there is provided a conveying device, generally designated 2 , which conveys the container closures 10 . In this embodiment, in this case, the container closures 10 move substantially on end on a horizontal belt. Reference numeral 52 designates a single-stroke wheel which allows individual supply of container closures to the conveyor 2 . In this case, the container closure 10 moves relative to the rail 54 arranged in a stationary manner.

A closure sterilization arrangement for container closures comprises a conveying device that conveys the container closures separately along a conveying path so that they avoid touching one another. An irradiation device generates a radiation sterilizing the container closures and acts upon the container closures with the radiation during the conveying thereof by the conveying device. A rotating device rotates the container closures about a pre-set axis of rotation at least for a time period during their conveying by the conveying device. The irradiation device is arranged with respect to the conveying path of the container closures so that the radiation issuing from the irradiation device strikes both an external peripheral wall of the container closures and an internal region of the container closures, and the irradiation device irradiates the container closures from at least two different radiation directions.
Description
technical field [0001] The present invention relates to an apparatus and method for radiation-based sterilization of container closures. Background technique [0002] Various methods of sterilizing container closures are known in the prior art. In this context, it is known on the one hand to sterilize container closures with chemical media such as hydrogen peroxide. However, in recent years, the use of chemical agents has been eliminated to some extent in the sterilization process in this way. [0003] Devices and methods for sterilizing container closures by radiation are therefore also known from the prior art. Radiation is understood in the following to be in particular the radiation of charge carriers, ie, for example, the formation of pressure with electrons. In addition, however, the radiation can also be radiation of different types, for example UV radiation, radioactive radiation, X-ray radiation or the like.
