Bag puncturing means.

摘要

A bag puncturing means to couple to a socket outlet (5) of a plastic liner bag (4) of a liquid container where the socket (5) is closed of by a portion (6) of the plastic bag (4). The puncturing means comprises a connector (7) engagable in the socket (5) and movable linearly in the socket (5) and having a liquid passing opening through the connector (7) housing a coiled compression spring (9) which extends from the connector (7) and is longer than the socket (5) and a cutter (16) which is caused to penetrate the socket closing portion (6) of the bag (4) by relative movement between the connector (7) and the socket (5) thereby allowing the spring (9) to enter into the bag (4).
