Beverage container lid with reservoir and repetitive measuring and disbursement mechanism

A lid positionable at an open upper end portion of a beverage container having an interior cavity for holding a beverage, comprising:

• a reservoir chamber sized to hold a drink additive;
• a measurement chamber in fluid communication with the reservoir chamber, and when the lid is at least partially within the open upper end portion of the beverage container, the measurement chamber is in fluid communication with the interior cavity of the beverage container;
• a plunger having at least one seal, the plunger having an upper plunger end portion with a filler port sized and positioned to receive drink additive and an aperture in fluid communication with the reservoir chamber, the upward plunger end portion arranged to pass drink additive entering the filler port to the aperture in fluid communication with the reservoir chamber to provide the drink additive to the reservoir chamber;
• and
• an actuator operably connected to the plunger to move the plunger between first, second and third plunger positions,
• (a) in the first plunger position the at least one seal configured to provide fluid communication between the reservoir chamber and the measurement chamber for permitting drink additive in the reservoir chamber to flow into the measurement chamber but not between the measurement chamber and the interior cavity of the beverage container,
• (b) in the second plunger position the at least one seal configured to confine a first quantity of drink additive in the measurement chamber and maintain the first quantity of the drink additive separate from the remainder of the drink additive in the reservoir chamber, and
• (c) in the third plunger position the at least one seal configured to permit the first quantity of drink additive to flow into the interior cavity of the beverage container while preventing additional drink additive in the reservoir chamber to flow into the interior cavity of the beverage container.
