Abstract

An apparatus for sterilizing containers, comprises a transport device which transports the containers along a predefined transport path and at least one sterilization device which bombards the containers with charge carriers for sterilization during a transport of the containers along the transport path. The at least one sterilization device comprises a generating device for generating charge carriers. The apparatus further comprises a screening device for screening radiation. The screening device surrounds the transport path of the containers at least in portions. The screening device comprises: a first wall adjacent the transport path of the containers; and a second wall below the transport path of the containers, wherein the second wall is movable relative to the transport path of the containers.

First claim

What is claimed is:

1. An apparatus for sterilizing containers, comprising:
transfer stars which transport the containers along a predefined transport path;
at least one sterilization device which comprises an electron-generating device for generating charge carriers and which bombards the containers with charge carriers for sterilization of the containers during a transport of the containers along the transport path; and
a screening device for screening radiation, the screening device surrounding the transport path of the containers at least in portions, wherein the screening device comprises:
a first wall adjacent the transport path of the containers; and
a second wall below the transport path of the containers, wherein the second wall includes a floor wall, and is movable relative to the transport path of the containers, and wherein a movement of the second wall exposes an accessible opening to the at least one sterilization device for operator intervention, wherein the opening is sufficiently large for an operator to carry out maintenance work through the opening.

2. The apparatus of claim 1 , wherein the transport device has a movable carrier, and wherein the apparatus further comprises a plurality of holding elements on the movable carrier that hold the containers.

3. The apparatus of claim 1 , wherein the second wall is movable in a longitudinal direction of the containers to be sterilized.

4. The apparatus of claim 1 , wherein the screening device at least in portions has a third wall which extends at the side adjacent the transport path of the containers, wherein the transport path at least in portions extends between the first wall and the third wall.

5. The apparatus of claim 4 , wherein the third wall is movable relative to the first wall.

6. The apparatus according to claim 1 , wherein the screening device substantially completely surrounds the transport path of the containers.

7. The apparatus according to claim 1 , wherein the walls form an isolator within which the containers are transported.

8. The apparatus according to claim 7 , wherein the isolator is configured to be opened in full or at least in part.

9. The apparatus according to claim 8 , wherein the isolator is opened downwards or is opened downwards by a shift movement of a floor region.

10. The apparatus according to claim 1 , wherein the apparatus has an interior bombardment device for sterilizing at least a portion of an inner wall of the containers and an exterior bombardment device for sterilizing at least a portion of an outer wall of the containers.

11. An apparatus for sterilizing containers, comprising:
transfer stars which transport the containers along a predefined transport path;
at least one sterilization device which comprises an electron-generating device for generating charge carriers and which bombards the containers with charge carriers for sterilization of the containers during a transport of the containers along the transport path; and
a screening device for screening radiation, the screening device surrounding the transport path of the containers at least in portions, wherein the screening device comprises:
a first wall adjacent the transport path of the containers; and

a second wall below the transport path of the containers, wherein the second wall is movable relative to the transport path of the containers, wherein the transfer stars have a movable carrier, and wherein the apparatus further comprises a plurality of holding elements on the movable carrier that hold the containers.

12. An apparatus for sterilizing containers, comprising:
transfer stars which transport the containers along a predefined transport path;
at least one sterilization device which comprises an electron-generating device for generating charge carriers and which bombards the containers with charge carriers for sterilization of the containers during a transport of the containers along the transport path; and
a screening device for screening radiation, the screening device surrounding the transport path of the containers at least in portions, wherein the screening device comprises:
a first wall adjacent the transport path of the containers; and
a second wall below the transport path of the containers, wherein the second wall is movable relative to the transport path of the containers, and wherein the screening device at least in portions has a third wall which extends at the side adjacent the transport path of the containers, wherein the transport path at least in portions extends between the first wall and the third wall, and wherein the third wall is movable relative to the first wall.

13. The apparatus according to claim 12 , wherein the third wall and the first wall form a channel within which the containers are transported.

14. The apparatus according to claim 13 , wherein the containers are sterilized on their outer surface during their transport through the channel.

15. The apparatus according to claim 12 , wherein the third wall is arranged on the second wall and/or a movement of the third wall is coupled to a movement of the second wall.

16. The apparatus according to claim 12 , wherein the second wall includes a floor wall.

17. The apparatus according to claim 12 , wherein the containers are transported for sterilization through a transport channel, and wherein the transport channel is formed by at least two side walls and the second wall.
