Abstract
The invention pertains to a coupling for a liquid product packaging and dispensing assembly in which liquid is pumped from a container via the coupling through a tube to the point of use. The coupling has a first interconnectable member with a hollow post and a biased sleeve closing openings in the hollow post and a second interconnectable member with a hollow sheath and a biased piston closing an opening at the end of the sheath. The parts are configured so that, upon connection, the post unseats the piston while the sheath displaces the sleeve, thereby allowing liquid flow. An elastic ring is present between the sheath and the sleeve which ring is compressed in the axial direction and expanded in the radial direction toward the post so as to establish a close fit around the post.
