Abstract

A device for filling a fill product into a container to be filled in a beverage bottling plant. The device includes a fill product reservoir for storing the fill product, a fill product channel, and a filling member in fluid communication with the fill product reservoir via the fill product channel. The filling member is configured to introduce the fill product into the container to be filled and the filling member communicates via media channels to provide media flows for two or more functions: flushing the container with a flushing gas, pre-pressurizing the container before it is filled, returning gas displaced during the filling of the container, relieving a gas overpressure in the container, and circulating a hot fill product through the filling member for controlling a temperature. A single media channel of the media channels is configured to provide the media flows for at least two of the functions.

First claim

The invention claimed is:

1. A device for filling a fill product into a container to be filled in a beverage bottling plant, the device comprising:
a fill product reservoir for storing the fill product;
a fill product channel; and
a filling member in fluid communication with the fill product reservoir via the fill product channel, wherein the filling member is configured to introduce the fill product into the container to be filled and the filling member communicates via media channels to provide media flows for two or more functions:
flushing the container with a flushing gas before it is filled with the fill product,
pre-pressurizing the container with a pressurizing gas to a pre-pressurizing pressure before it is filled with the fill product,
returning gas displaced during the filling of the container with the fill product,
relieving a gas overpressure in the container after filling the container with the fill product, and
circulating a hot fill product through the filling member for controlling a temperature of the filling member,

wherein in a first operating state the fill product is carbonated and in a second operating state the fill product is a hot-fill product, and
wherein a single media channel of the media channels is configured to provide the media flows for at least two of the functions, including during the first operating state the single media channel is configured to relieve the gas overpressure which has built up in the container after filling with the fill product and during the second operating state the single media channel is configured to circulate the hot fill product through the filling member for controlling the temperature of the filling member.

2. The device according to claim 1 , wherein the single media channel is configured to provide the media flow to flush the container before it is filled with the fill product and to pre-pressurize the container to the pre-pressurizing pressure before it is filled with the fill product.

3. The device according to claim 1 , wherein the single media channel during the first operating state is further configured to provide the media flow for flushing the container before it is filled with the fill product and to pre-pressurize the container to the pre-pressurizing pressure before it is filled with the fill product and during the second operating state is further configured to provide the media flow to allow the gas displaced from the container during filling of the fill product to flow back.

4. The device according to claim 1 , wherein the single media channel comprises a further switch valve for selectively providing fluid communication with one of the following: the fill product reservoir, the fill product channel, and an environment surrounding the device.

5. The device according to claim 1 , wherein the filling member includes a return-switch valve for providing a fill product stream from the filling member into the single media channel,
wherein a second media channel, during the second operating state that is configured to provide the media flows for returning the gas displaced during filling of the container with the fill product, includes:
a switch valve and/or a non-return valve for preventing a gas stream from entering the fill product reservoir, and
a venting valve for releasing the gas stream from the second media channel into an environment surrounding the device, wherein the venting valve is controllable/adjustable via a switch position of the switch valve and/or of the non-return valve.

6. The device according to claim 5 , wherein the filling member includes a filling valve and the return-switch valve is adapted in the second operating state, with the filling valve closed, to allow the fill product which has flowed from the fill product channel into the filling member to flow into the single media channel that is configured to provide the media for circulating the hot fill product.

7. The device according to claim 1 , wherein the media channels include only the single media channel and one other media channel to provide the media flows for all of the functions.

8. The device according to claim 1 , wherein the fill product reservoir is in the form of an adjacent fill product reservoir and the device further comprises a media distributor arranged between the fill product reservoir and the filling member and configured to distribute the media provided by the fill product reservoir.

9. The device according to claim 1 , wherein the single media channel is configured to provide the media flow for flushing and for pre-pressurizing the container is adapted to use the gas that has been displaced from the container into the single media channel during filling of the fill product into the container for flushing and/or pre-pressurizing at least one second container that is to be filled.

10. The device according to claim 1 , wherein a first media channel of the media channels figured to provide a media flow for flushing and/or pre-pressurizing the container comprises a pre-pressurizing valve for connecting the filling member to the first media channel and the single media channel comprises a relief valve for releasing the gas from the filling member into the single media channel.

11. The device according to claim 1 , further comprising a plurality of filling members that include the filling member.

12. The device according to claim 1 , wherein the gas that has been displaced from the container during filling of the fill product into the container and returned to a media channel of the media channels is provided for pre-pressurizing at least one second container.

13. The device according to claim 1 , wherein the single media channel during the first operating state is further configured to provide the media flow for flushing the container before it is filled with the fill product and to pre-pressurize the container to the pre-pressurizing pressure before it is filled with the fill product.

14. A method for filling a fill product into a container to be filled in a beverage bottling plant, the method comprising:
conveying the fill product from a fill product reservoir to a filling member;
filling, by the filling member, the container to be filled with the fill product; and
using media flows via media channels in communication with the filling member to perform two or more of the following functions:
flushing the container to be filled with a flushing gas before it is filled with the fill product,
pre-pressurizing the container with a pressurizing gas to a pre-pressurizing pressure before it is filled with the fill product,
returning gas displaced during the filling of the container with the fill product,
relieving a gas overpressure which has built up in the container after filling with the fill product, and
circulating a hot fill product through the filling member for controlling a temperature of the filling member,

wherein in a first operating state the fill product is carbonated and in a second operating state the fill product is a hot-fill product, and
wherein a single media channel of the media channels is configured to provide the media flows for at least two of the functions, including during the first operating state the single media channel is configured to relieve the gas overpressure which has built up in the container after filling with the fill product and during the second operating state the single media channel is configured to circulate the hot fill product through the filling member for controlling the temperature of the filling member.

15. The method according to claim 14 , wherein the single media channel is further
