Abstract
A drinking mug for dispensing a controlled volume of liquid to a user has a metering chamber with an inlet valve and an outlet valve. The outlet valve utilizing a floating ball which closes the outlet valve after a precise amount of fluid enters the metering chamber. The inlet valve utilizes a ball which sealingly engages the inlet orifice when the mug is tilted past a first angle, thereby preventing additional liquid from entering the metering chamber. As the mug is tipped past the first angle, the buoyancy of the floating ball disengages the ball from the outlet orifice, thereby allowing the fluid in the metering chamber to be dispensed to the user.
