Patent

CA 2619563

A liquid dispenser, such as a tap for a liquid container particularly a wine box, includes an outer tube (2) with a discharge opening (14) formed in its side wall and an inner tube (4), which is at least partially accommodated within the outer tube (2) and defines with it an annular space, which accommodates an annular sealing member (20), which forms a seal with the outer tube. One end of the inner tube (4) is closed and one end of the outer tube (2) is integrally connected to the inner tube (4) by a flexible, integral annular web (10), whose width in the radial direction is greater than that of the annular space. The other end of the outer tube (2) is adapted for connection to the liquid container. The inner tube (4) is movable longitudinally within the outer tube (2) between an open position, in which there is a liquid flow path between the said outer end of the outer tube and the discharge opening (14), and a closed position, in which the outer surface of the inner tube (4) forms a sliding seal with sealing member (20) and the said liquid flow path is sealed.

L~invention concerne un distributeur de liquide, comme par exemple un robinet pour conteneur de liquide en particulier un cubitainer de vin, comprenant un tube externe (2) avec une ouverture de décharge (14) constitué dans sa paroi latérale et un tube interne (4), qui est au moins partiellement logé dans le tube externe (2) et définit avec lui un espace annulaire, qui reçoit un élément d~étanchéité annulaire (20), qui forme un joint avec le tube externe. Une extrémité du tube interne (4) est fermée et une extrémité du tube externe (2) est solidarisée avec le tube interne (4) par une trame annulaire intégrale flexible (10), dont la largeur dans la direction radiale est supérieure à celle de l~espace annulaire. L~autre extrémité du tube externe (2) est adaptée pour se connecter au conteneur de liquide. Le tube interne (4) est mobile longitudinalement dans le tube externe (2) entre une position ouverte, dans laquelle il existe un circuit de liquide entre ladite extrémité externe du tube externe et l~ouverture de décharge (14), et une position fermée, dans laquelle la surface externe du tube interne (4) forme un joint coulissant avec l~élément d~étanchéité (20) et ledit circuit de liquide est scellé.
