LIQUID EXTRACTION SYSTEM WITH REDUCED EXPOSURE TO AIR

摘要

A liquid extraction apparatus and a method of extracting a liquid from a container and storing the liquid are disclosed. The method includes inserting a liquid extraction member into a container and creating a pressure differential to cause the liquid to flow into a storage vessel. An apparatus for extracting a liquid from a container comprises a shiftable plunger received in the storage vessel and operable to create a pressure differential between the storage inlet and the extraction inlet to draw the liquid from the container, through the extraction member, and into the storage vessel; and an air blocking member received in the extraction member and shiftable between an initial blocking position and a final extraction position, where the air blocking member presents a lowermost surface that moves through a total distance as the air blocking member is shifted from the initial blocking position to the final extraction position.
