发明名称 FILTER TIL FLASKEPAAFYLDNING
摘要 A disposable vacuum assisted filter funnel for filtering fluids into bottles. The bottle top filter forms a vacuum dependent seal with the mouth of the bottle. When fluid is introduced into the bottle top filter, the evacuated bottle draws the fluid through the filter into the bottle. The bottle top filter lacks a vacuum plenum between the vacuum source and the bottle. The bottle top filter may be manufactured from one molded piece.
