Abstract

A device for producing filled containers has a transport device which is configured for transporting containers which are filled with a liquid and are closed by a closure. Furthermore, the apparatus has a penetration device which is configured for producing an opening in at least one region of the closure and/or of the container, and an application device, which applies a flowable and in particular gaseous medium to the interior of the container through this opening (or feeds the gaseous medium to this interior). Furthermore, the apparatus has a closing device which closes the opening again.

First claim

The invention claimed is:

1. An apparatus for producing filled containers with a transport device which is configured for transporting containers which are filled with a liquid and closed by a closure, with a penetration device which is configured to produce an opening in at least one region of the closure and/or of the container, with an application device which is configured to apply a flowable and in particular gaseous medium to an interior of the container through the opening, and with a closing device which is configured to close the opening, wherein the apparatus has at least one cleaning and/or sterilising device, which is configured for cleaning and/or sterilising at least one device of the application device, and wherein the cleaning and/or sterilising device is configured to apply a flowable cleaning medium to devices of the application device, wherein the cleaning and/or sterilising device is active in a cleaning mode, which differs from an operating mode, in which the containers themselves are processed.

2. The apparatus according to claim 1 , wherein the application device has at least one feed conduit configured to feed the medium to the interior of the container and the sterilising device is configured for flushing the feed conduit with a cleaning and/or sterilising medium.

3. The apparatus according to claim 1 , wherein the cleaning and/or sterilising device has at least one stationary feeding device for a cleaning and/or sterilising medium.

4. The apparatus according to claim 1 , wherein the application device is arranged on the transport device.

5. The apparatus according to claim 1 , wherein the apparatus has a distribution device configured to distribute at least one flowable medium from a stationary feeding device to a plurality of application devices.

6. The apparatus according to claim 1 , wherein the apparatus has a stationary supply device configured to supply the flowable medium.

7. The apparatus according to claim 6 , wherein the apparatus has a selection device configured to enable selective feeding of the application device with the flowable medium or the cleaning and/or sterilising medium.

8. A method for producing containers which are filled with liquids and closed, wherein containers filled with a liquid and closed by a closure are transported by a transport device, and an opening is produced in at least one region of the closure and/or of the container by a penetration device, and wherein in a first operating mode a flowable and in particular gaseous medium is applied to an interior of the container through the opening by an application device, and then the opening is closed again by a closing device, wherein in a second operating mode at least one device of the application device is cleaned and/or sterilised by a cleaning and/or sterilising medium, and wherein the cleaning and/or sterilising device is configured to apply a flowable cleaning medium to devices of the application device, wherein the cleaning and/or sterilising device is active in a cleaning mode, which differs from an operating mode, in which the containers themselves are processed.

9. The method according to claim 8 , wherein the cleaning and/or sterilisation takes place by a flowable cleaning and/or sterilising medium.

10. The method according to claim 9 , wherein the cleaning and/or sterilising medium is provided by a stationary feeding device.

11. The method according to claim 8 , wherein the cleaning and/or sterilising medium is provided by a stationary feeding device.

12. The method according to claim 8 , wherein the apparatus has a sterile room inside which the containers are at least partially transported.

13. The method according to claim 8 , wherein an inspection device is provided, which facilitates thermal monitoring of the welding point.

14. The method according to claim 8 , wherein a plurality of feed conduits for the flowable medium are cleaned with the cleaning and/or sterilising medium.

15. The method according to claim 8 , wherein the cleaning and/or sterilising medium is provided via the same route as the flowable medium which is applied to the containers.
