Abstract
The known liquid filling apparatus of the type including a housing, an annular liquid feed passageway, a liquid valve, a holding member and a gas pipe, is improved so as to facilitate cleaning of the interior of the apparatus, so as to be applicable to a container having a small mouth diameter, and so as to facilitate replacement of a gas pipe. The improvement resides in that, on the inner circumferential side of the holding member disposed slidably along the housing, are disposed a circular ring provided slidably along the same inner circumferential surface and a spring for normally biasing the circular ring in the downward direction. A desired gap space is provided between a lower surface of the circular ring and an upper surface of a positioning conical cylinder having a sealing element for the mouth edge portion of a container to be filled with liquid by fixing a bend member fitted around the outer circumferential surface of the gas pipe to the circular ring and fixing the positioning conical cylinder to the holding member.
