Abstract

A device for treating containers, for example, for filling and closing containers in filling plants is described. The device includes an isolator chamber in which the treatment of the containers takes place, and an outlet disposed beneath the isolator chamber for discharging fluids, wherein the outlet has a housing for receiving ejected containers and a suction device for extracting gases from the isolator chamber.

First claim

The invention claimed is:

1. A device for treating containers, comprising:
an isolator chamber where treatment of the containers takes place;
an outlet configured to discharge fluids and connected to a floor of the isolator chamber;
a suction device configured to extract gases from the isolator chamber and connected to the outlet;
a cleaning-in-place system configured to recycle a cleaning medium, clean the isolator chamber with the cleaning medium and circulate the cleaning medium, wherein the cleaning-in-place system is disposed downstream of the outlet in a direction of flow of the cleaning medium;
a closer configured to close the containers in the isolator chamber; and
a filler configured to fill the containers in the isolator chamber;
wherein:
the outlet comprises (1) an outlet valve disposed downstream of the connection of the suction device to the outlet in the direction of flow of the cleaning medium (2) a pump disposed downstream of the outlet valve and configured to pump out the cleaning medium and (3) connecting lines extending from below the floor of the isolator chamber towards the outlet valve,
the outlet valve is configured to close the outlet during intervals between cleanings of the isolator chamber,
the isolator chamber is divided into a filler chamber to accommodate the filler and a closer chamber to accommodate the closer, and
wherein the connecting lines comprise a connecting line extending from below a floor of each of the filler chamber and the closer chamber.

2. The device of claim 1 , wherein the suction device comprises a suction line.

3. The device of claim 2 , further comprising a moisture separator configured to separate moisture at the suction device, wherein the moisture separator is disposed on the outlet.

4. The device of claim 1 , wherein the suction device comprises an extraction fan.

5. The device of claim 1 , further comprising a preform blowing device configured to stretch blow mold plastic preforms.

6. The device of claim 1 , wherein the suction device and the outlet valve are disposed on different lines.

7. A device for treating containers, comprising:
an isolator chamber where treatment of the containers takes place;
an outlet configured to discharge fluids and connected to a floor of the isolator chamber;
a suction device configured to extract gases from the isolator chamber and connected to the outlet;
a cleaning-in-place system configured to recycle a cleaning medium, clean the isolator chamber with the cleaning medium and circulate the cleaning medium, wherein the cleaning-in-place system is disposed downstream of the outlet in a direction of flow of the cleaning medium;
a closer configured to close the containers in the isolator chamber; and
a filler configured to fill the containers in the isolator chamber,
wherein:
the outlet comprises (1) an outlet valve disposed downstream of the connection of the suction device to the outlet in the direction of flow of the cleaning medium, (2) a pump disposed downstream of the outlet valve and configured to pump out the cleaning medium, and (3) connecting lines extending from below the floor of the isolator chamber towards the outlet valve,
by closing the outlet valve, a level of the cleaning medium in the isolator chamber is adjusted,
the outlet valve is configured to close the outlet during intervals between cleanings of the isolator chamber,
the isolator chamber is divided into a filler chamber to accommodate the filler and a closer chamber to accommodate the closer, and
wherein the connecting lines comprise a connecting line extending from below a floor of each of the filler chamber and the closer chamber.

8. The device of claim 7 , wherein the outlet comprises a housing configured to receive ejected containers.

9. The device of claim 8 , wherein the housing is integrated with the isolator chamber.

10. The device of claim 8 , wherein the housing comprises:
an inlet aperture disposed on an upper face of the housing that communicates with the isolator chamber,
an outlet aperture disposed in a lower area of the housing configured to discharge fluid,
a container guide disposed in the housing at least between the inlet aperture and the outlet aperture, and
a removal aperture configured to be opened or closed.

11. The device of claim 10 , wherein the container guide comprises a perforated metal plate or a plurality of rods.

12. The device of claim 10 , wherein the container guide and/or a floor of the housing is inclined relative to a vertical axis of the housing.

13. The device of claim 10 , wherein the inlet aperture comprises an inlet closing device configured to interrupt communication between the housing and the isolator chamber.

14. The device of claim 7 , further comprising a preform blowing device configured to stretch blow mold plastic preforms.

15. The device of claim 7 , wherein the suction device comprises a suction line.

16. The device of claim 7 , further comprising a moisture separator configured to separate moisture at the suction device, wherein the moisture separator is disposed on the outlet.

17. The device of claim 7 , wherein the suction device comprises an extraction fan.

18. The device of claim 7 , wherein the suction device and the outlet valve are disposed on different lines.
