Abstract
A cylindrical housing 6 is secured to the bottom surface of an elevatable filling liquid tank 2, and a liquid injection pipe 16 is mounted on the bottom of the housing 6. An exhaust pipe 18 axially passes through the housing 6 and the liquid injection pipe 16, and is disposed for elevating movement. The exhaust pipe 18 is driven by an elevating mechanism 21. A holder 54 carrying a bottle mouth stuffing 52 is fitted in the housing 6, and is urged down by a spring 61. The bottle mouth stuffing 52 tightly engages the mouth of a vessel which is being raised as carried on a vessel receptacle, and accordingly its position is determined by the height of the vessel. The position of the liquid injection pipe 16 and the exhaust pipe 18 is modified in accordance with the elevation of the tank 2, independently from the bottle mouth stuffing 52. Accordingly, a void which remains in the top of the vessel after the vessel is filled with the liquid is adjusted only in accordance with the elevation of the tank 2.
