Bell-Shaped Protection System for a Device for Treating Electron-Beam Containers

Processing device comprising

• at least one treatment station for the sterilization of containers via electron beams, each said treatment station comprising sterilization means which comprise an electron-beam emitter provided with a tubular nozzle and supporting means for supporting a container under said emitter, said emitter able to emit an electron beam passing through an upper opening of a container supported by said supporting means in order to sterilize said container, and
• a protection system in order to stop radiation emitted by the emitter,
• wherein said protection system comprises, for each said treatment station,
• an upper portion assembled to the emitter, said upper portion having a shape of a bell formed from a first plate and from a tubular wall, said emitter being mounted on said first plate and said tubular nozzle extends substantially vertically under the first plate,
• a lower portion comprising a second plate, constituting said supporting means, and
• moving means able to carry out a relative movement of the upper portion in relation to the lower portion between a retracted position wherein the upper portion is separated from the lower portion, in order to allow for the positioning under the emitter of a container supported by the supporting means, and operative positions wherein the upper portion and the lower portion form a protective enclosure wherein are positioned the emitter and the container supported by the supporting means, the second plate being arranged in the bell when the upper portion is in an active position, said moving means able to move the upper portion between a first operative position wherein a distal end of the tubular nozzle is arranged above an upper opening of the container and an extreme operative position wherein said tubular nozzle extends in the container.
