Abstract
The fluid dispensing device includes a tubular spout attachable to a fluid-containing vessel, such as a bag, the spout including an outer end portion of a first lateral dimension and an inner portion of a smaller lateral dimension. A valve member is slidable in the spout, the valve member being tubular and having an open outer end adapted to receive a fluid-transmitting probe and a closed inner end. The valve member has openings through its sidewall. The outer end portion of the valve member is laterally outwardly deflectable and includes localized protrusions adapted to enter the recess of a probe. In the closed position of the valve member, opposed shoulders of the valve member and of the spout resist axial movement of the valve member in either direction, and interengaged sealing surfaces block fluid flow to the openings. The outwardly deflectable portion of the valve member can be deflected as the probe enters, and the protrusions thereafter spring inwardly into the recess of the probe. The valve member then is movable by the probe to an inner open position in which the openings are uncovered, and the protrusions in the probe recess allow the valve member to be moved back to th…
