Connector for connecting a container to a dispensing conduit

A connector for connecting a container to a dispensing conduit, wherein the connector comprises:

• a base provided with
• a tubular wall,
• a bottom wall oriented radially with respect to a main axis and closing a first end of the tubular wall, and
• at least one through-opening provided in the bottom wall and/or in the tubular wall;
• a membrane provided with
• an annular flexible wall having a central opening,
• a tubing placed in the central opening of the annular flexible wall so that it projects axially on one side of the flexible wall, and
• a conduit passing right through the tubing;
• and
• sealing means for preventing a liquid from leaving the connector through the conduit of the tubing, wherein
• the base and the membrane are fixed to each other in a liquid-tight manner so that the tubing projects outside the connector,
• the flexible wall is dimensioned to allow axial displacement of the tubing relative to the bottom wall so that the tubing can be moved between a closed position, in which the sealing means prevent the liquid from leaving the connector through the conduit of the tubing, and an open position, which is located farther axially from the bottom wall than the closed position, and in which the sealing means do not prevent the liquid from leaving the connector through the conduit of the tubing, and
• retaining means are provided to maintain the tubing in the closed position with a force that is sufficient to resist the pressure exerted by the liquid contained in the container equipped with the connector but can be overcome manually to move the tubing into the open position.
