Abstract

A treatment head for cleaning a container that has a valve arrangement that includes a tappet that is configured to move relative to the treatment head's housing to open the valve arrangement and fluid channels leading into the container. A first channel of the fluid channels has an annular fluid channel section and surrounds the second channel. A flow twister is disposed in either the first channel or in a line connected to the first fluid-channel.

First claim

The invention claimed is:

1. An apparatus comprising a treatment head for cleaning a container that has a valve arrangement, wherein said treatment head comprises a tappet, a housing, a first fluid-channel, an annular fluid-channel section, a second fluid-channel, and a flow twister, wherein said tappet is configured to move relative to said housing to open said valve arrangement, wherein said first fluid-channel comprises said annular fluid channel section, wherein said first fluid-channel circumferentially surrounds said second fluid-channel, wherein said first and second fluid-channels provide fluid communication into said container, and wherein said flow twister is disposed in a location selected from the group consisting of said first fluid-channel and a fluid line connected to said first fluid-channel.

2. The apparatus of claim 1 , wherein said flow twister comprises a twist body, wherein said twist body is disposed at said location, wherein said twist body comprises fluid channels, and wherein said fluid channels run obliquely to a flow direction leading to said location.

3. The apparatus of claim 1 , wherein said flow twister comprises a fluid line leading into said housing, said fluid line having a contoured wall.

4. The apparatus of claim 1 , wherein said flow twister comprises contoured walls of said first fluid-channel.

5. The apparatus of claim 1 , wherein said flow twister comprises a grooved wall of said first fluid-channel, wherein grooves of said grooved wall extend obliquely relative to a flow direction leading to said location.

6. The apparatus of claim 1 , wherein said first fluid-channel has a central axis and wherein fluid that enters said first fluid-channel does so along an off-center direction that misses said central axis.

7. The apparatus of claim 1 , further comprising a deflector, wherein said deflector is disposed to divert fluid flow into said first fluid-channel so that said fluid enters along an off-center direction that misses a central axis of said first fluid-channel.

8. The apparatus of claim 1 , wherein said valve arrangement comprises an annular passage, wherein when said container is arranged at said treatment head, said first fluid-channel connects to said annular passage.

9. The apparatus of claim 1 , further comprising a container-treatment machine, wherein said container-treatment machine comprises said treatment head.

10. A method comprising cleaning a container that comprises a valve arrangement, wherein cleaning said container comprises using a treatment head that has a tappet, a housing, a first fluid-channel, an annular fluid-channel section, a second fluid-channel, and a flow twister, wherein said tappet is configured to move relative to said housing to open said valve arrangement, wherein said first fluid-channel comprises said annular fluid channel section, wherein said first fluid-channel circumferentially surrounds said second fluid-channel, wherein said first and second fluid-channels provide fluid communication into said container, and wherein said flow twister is disposed in a location selected from the group consisting of said first fluid-channel and a fluid line connected to said first fluid-channel, said method comprising causing fluid that is supplied into said container via said first fluid-channel to be set into one of a spiral and helical fluid flow at a location selected from the group consisting of said first fluid-channel and a line connected to said first fluid-channel, and, after said spiral or helical fluid flow enters said container, producing a flow swirl around said valve arrangement.

11. The apparatus of claim 1 , wherein said tappet comprises obliquely oriented surfaces formed thereon.

12. The apparatus of claim 1 , wherein said annular fluid-channel section surrounds said tappet and wherein a fluid line that directs fluid into said annular section has a longitudinal axis that fails to intersect a central axis of said first fluid channel.

13. The apparatus of claim 1 , further comprising a deflector that causes flow that is directed toward a central axis of said first fluid channel to veer away from said central axis.

14. The apparatus of claim 1 , wherein said flow twister comprises obliquely running fluid channels that run through an upper tappet-part of said tappet comprises an upper tapper-part that contacts said valve arrangement.

15. The apparatus of claim 1 , wherein said flow twister is disposed in said first fluid-channel.

16. The apparatus of claim 1 , wherein said flow twister is disposed in said fluid line connected to said first fluid-channel.

17. The apparatus of claim 1 , wherein said tappet comprises an upper tapper-part that contacts said valve arrangement and wherein said flow twister comprises fluid channels running through said upper tappet-part in a spiral direction.

18. The apparatus of claim 1 , wherein said tappet comprises grooves formed thereon.

19. The apparatus of claim 1 , wherein said flow twister is configured to cause flow that has a straight-line component and a further component that is transverse to said straight-line component.
