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.

Abstract: Some paste or liquid products, used as cosmetics and medicines, for example, have to be protected from contact with air. Methods have been developed for vacuum packaging them. These methods are more concerned with eliminating air that may remain in the packaging filled with the product at the time the latter is closed (by welding, by sealed fixing of a dispensing valve, etc). No special precautions are taken during filling of the packaging which is carried out in air and inevitably causes unwanted air bubbles to be trapped. The present method avoids any inclusion of air in the product. The packaging, which consists of a variable volume reservoir, is filled while in its maximum content configuration in an hermetically sealed enclosure that is evacuated. The enclosure is formed by a bucket receiving the reservoir and to which a bell fits in a sealed way. The bell is connected to a system of vacuum pumps and to a store of the product.
