Patent ID: 7739859

Claim:
Apparatus, comprising a rotating conveying system for conveying along a curved path components of packaging units comprising containers and container closures, a filling device for filling with a product said containers on said rotating conveying system, a sterilising device for sterilising at least part of said components, said sterilising device being mounted along said path, said sterilising device comprising a first sterilising device for sterilising said containers arranged upstream of a carousel of said rotating conveying system in which said containers are filled and provided with said container closures, wherein said sterilising device further comprises a second sterilising device for sterilising said container closures on said carousel, said second sterilising device being arranged on the periphery of said carousel, wherein said sterilising device comprises an irradiating device arranged to emit a beam of electrons, and further comprising an orientation device for positioning said beam of electrons, said orientation device being arranged to direct said beam of electrons to sterilise each surface zone of said container closures; and wherein said sterilising device comprises a further irradiating device arranged to emit a further beam of electrons and a further orientation device for positioning said further beam of electrons, said further orientation device being arranged to direct said further beam of electrons to each surface zone to sterilise said containers; said further beam of electrons having a trajectory inclined with respect to the vertical axis of the container such that an angle of incidence on an internal wall of the container ensures a reflection of the further beam that ensures penetration of said further beam over the whole height of the container; said beam of electrons having a trajectory inclined with respect to the vertical axis of the container closure such that an angle of incidence on an internal wall of the container closure ensures a reflection of the beam that ensures penetration of the beam over the whole height of the container closure; and said orientation device being provided for relative movement between said beam of electrons and said container closure, said further orientation device being provided for relative movement between said further beam of electrons and said containers.
