Abstract:
1. A fluid dispensing system for regulated transfer of a fluid composition to a recipient device, such dispensing system comprising: (a) a container having upper and lower ends for containing the fluid composition, the container having a hollow neck extending upwardly from the upper end which has interior and exterior surfaces; (b) a dispenser base having an outlet port therein; (c) means for operatively connecting the neck of the container to the dispenser base; (d) a hollow probe extending from the dispenser base above the outlet port, such hollow probe having at least one inlet port therein; (e) a valve assembly inserted into the neck of the container in abutted relationship with the interior surface of the neck, the valve assembly having a valve housing with at least one inlet opening and one outlet opening, a valve body contained within the valve housing for reciprocation between a closed position wherein the valve body blocks the valve housing outlet opening to prevent passage of the fluid composition from the container, and an open position wherein the valve body is removed from the valve housing outlet opening to permit passage of the fluid composition from the container, and a spring for positively biasing the valve into its closed position; (f) means for delivering fluid composition from the outlet port of the dispenser base to the recipient device; (g) wherein connection of the container to the dispenser base causes the probe to engage the valve body to move it to its open position whereupon fluid composition may freely flow from the container through the dispenser base outlet port; and (h) wherein disconnection of the container from the dispenser base removes the probe from engagement with the valve body, so that the spring promptly biases the valve body to its closed position to substantially prevent spillage of fluid composition from the container without use of an elastomeric seal within the valve assembly between the valve body and the outlet opening.
