Patent

CA 2355207

A valve apparatus utilizes a biased flap (5) and air hole (30) to regulate the flow of a fluid from the orifice (8) of a container (18). The biased flap (5) progressively opens in response to increasing fluid pressure upon the flap. An additional air hole (150) is preferably used to permit air to continuously enter the container while fluid is discharged. A substantially smoother pouring response is achieved.

L'invention concerne un dispositif de régulation mettant en oeuvre un clapet sollicité par effet ressort (5) et un évent (30) permettant de réguler l'écoulement d'un liquide à partir de l'ouverture (8) d'un récipient (18). Le clapet (5) s'ouvre de manière progressive en réaction à la pression croissante du liquide qui s'exerce sur lui. On utilise de préférence un évent supplémentaire (150), permettant une entrée constante de l'air dans le récipient au fur et à mesure que le liquide est versé. On obtient ainsi un débit sensiblement plus homogène.
