Patent

CA 2373864

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 comprises a first interconnectable member (19) with a hollow post (12) and a biased sleeve (15) closing openings in the hollow post and a second interconnectable member (20) with a hollow sheath (29) and a biased piston (25) closing an opening at the end of the sheath. The parts are configured so that, upon connection, the post (12) unseats the piston (25) while the sheath displaces the sleeve, thereby allowing liquid flow. The piston and the post are configured such that, upon connection, any fluid residing between them is displaced.

La présente invention concerne un couplage destiné à un ensemble emballage et distributeur de produit liquide dans lequel le liquide est pompé dans un récipient via le couplage en passant par un tube et aboutissant au point d'utilisation. Le couplage est fait, d'une part d'un premier élément interconnectable constitué d'un massif vertical creux et d'un manchon sous charge de ressort fermant des orifices dans le massif vertical creux, et d'autre part d'un second élément interconnectable constitué d'une gaine creuse et d'un piston sous charge de ressort fermant un orifice à l'extrémité de la gaine. La configuration des pièces est conçue pour qu'à la connexion, le massif vienne dégager le piston pendant que la gaine déplace le manchon, permettant par là-même au liquide de couler. La configuration du piston par rapport au massif est conçue pour qu'à la connexion, tout fluide retenu entre le piston et le massif se déplace.
