Arrangement for filling liquids into a container

A device for use in filling bottles with liquid stored in a reservoir is disclosed. The device utilizes a short gas conduit for venting the bottle to be filled. When the level of liquid reaches the level of the conduit, the outflow of gas displaced during the filling process ceases and the filling process is greatly slowed. Liquid which is drawn into the conduit is blocked by a check valve which does not impede gas flow. After such blockage, the device is so constructed as to allow the liquid to drain back into the bottle. This single conduit is used for both the intake and exhausting of gas, as may be required during the filling process.
