Abstract

A filler element includes a housing, a channel formed therein, a valve in the channel, an opening downstream from the valve that dispenses content into a container when the valve is open, a tube for fill-level adjustment, a controlled gas channel, and a collection space. The tube, which adjusts a fill level of content in the container, projects past the dispensing opening and extends into an interior of the container during filling thereof. This tube connects to a collection space separated from a content vat from which the content comes through the channel. To adjust the desired fill level, a gas pressure is applied to the interior through the tube, thereby displacing excess content from the container. The controlled gas channel permits the gas to enter the container interior.

First claim

Having described the invention, and a preferred embodiment thereof, what is claimed as new, and secured by Letters Patent is:

1. An apparatus for processing containers, said apparatus comprising a filler element for the filling of containers with liquid contents, said filler element comprising a liquid channel, a filler-element housing, a liquid valve, a dispensing opening, a tube for fill-level adjustment, a controlled gas channel, and a collection space, wherein said liquid channel is formed in said filler element housing, wherein said content is made available in a content vat from which content can flow through said liquid channel, wherein said liquid valve is in said liquid channel, wherein said dispensing opening is configured for dispensing content into a particular container when said liquid valve is open, wherein a flow direction of said liquid content defines an upstream direction and a downstream direction, wherein said dispensing opening is provided downstream of said liquid valve, wherein said tube is configured for adjusting a desired fill level of content in said container, wherein said tube comprises a first open end projecting past said dispensing opening and extending into an interior of said container during filling thereof, wherein, to adjust said desired fill level, a gas pressure is applied to said interior through said tube, thereby displacing excess content from said container, and wherein said controlled gas channel permits application of said gas into said container interior, wherein said tube is connected to said collection space, wherein said collection space is separated from said content vat, and wherein said collection space jointly serves plural filler elements.

2. The apparatus of claim 1 , further comprising a control valve, wherein said tube is connected to said collection space via said control valve.

3. The apparatus of claim 1 , further comprising a stop valve, wherein said collection space is connected to said content vat via said stop valve.

4. The apparatus of claim 1 , further comprising a switchover valve, wherein said collection space is connected to said content vat via said switchover valve.

5. The apparatus of claim 1 , further comprising a pipe, and a stop valve, wherein said stop valve connects said collection space to said pipe for draining content.

6. The apparatus of claim 5 , further comprising an installation for processing said content, wherein said pipe is connected to said installation.

7. The apparatus of claim 1 , wherein said collection space is an annular channel.

8. The apparatus of claim 1 , further comprising a rotary filling machine, wherein said rotary filling machine comprises a circulating rotor, wherein said filling element, together with a plurality of additional filling elements, is disposed on said circulating rotor.

9. The apparatus of claim 1 , wherein said tube is a trinox tube.

10. The apparatus of claim 1 , further comprising a pipe, and a switchover valve, wherein said switchover valve connects said collection space to said pipe for draining content.

11. A method comprising filling a container with liquid content using a filler element that comprises a dispensing opening downstream, as defined by a direction of flow of said liquid content, of a liquid valve, said method comprising opening said liquid valve to cause liquid content to be dispensed into said container through said dispensing opening, said liquid content having been supplied from a content vat from which said content flows through a liquid channel formed in a filler-element housing of said filler element, said liquid channel having said liquid valve therein, wherein filling said container further comprises extending, into said container, a first open end of a tube that is connected to a collection space separated from said content vat, said tube being configured for adjusting a desired fill level of content in said container, said first open end projecting past said dispensing opening and extending into an interior of said container, over-filling said container, upon completion of over-filling said container, passing gas through a controlled gas channel that permits application of gas into said container interior and through said tube to achieve a desired fill level of content by using gas pressure to force excess content out of a head space of said container, thereby adjusting said desired fill level by applying a gas pressure to said interior through said tube and displacing excess content from said container, and causing content displaced by said gas pressure to be collected in a collection space separated from said contents vat, wherein said collection space jointly serves plural filler elements.

12. The method of claim 11 , further comprising returning said content collected in said collection space to said content vat.

13. The method of claim 12 , further comprising processing said content collected in said collection space prior to returning said content to said content vat.

14. The method of claim 11 , further comprising selecting said tube to be a trinox tube.
