Measuring device and fluid dispenser

A container for dispensing fluids in metered amounts comprising:

• a housing defining a space;
• wall means mounted within said space for dividing said space into a first compartment and a second compartment;
• first valve actuator means mounted within said first compartment for selective movement from a first position through a second position to a third position and from said third position through said second position to said first position;
• second valve actuator means associated with said second compartment and movable between a first and second position;
• linkage means for interconnecting said first and second actuator means;
• fluid inlet valve means, gas inlet valve means and gas outlet valve means associated with said first valve actuator means for feeding fluid and gas to said second compartment and removing gas from said second compartment in response to the position of said first valve actuator means;
• fluid outlet valve means associated with said second valve actuator means for removing fluid from said second compartment in response to the position of said second valve actuator means;
• detent means for (1) holding said first valve actuator means in its first position wherein said fluid inlet valve means and gas outlet valve means are closed and said gas inlet valve means is open and (2) holding said second valve actuator means in its first position wherein said fluid outlet valve means is open;
• biasing means for (1) biasing said first valve actuator means from its first position to its third position and (2) said second valve actuator means from its first position to its second position upon release of said detent means wherein said fluid inlet valve means and gas outlet valve means are open and said gas inlet valve means and fluid outlet valve means are closed;
• and
• displacement means for moving said first valve actuator means from said third position through said second position to said first position wherein in its second position both of said fluid valve means and both of said gas valve means are closed.
