Drink additive delivery lid system

1. A drink additive lid system for selectively introducing a drink additive to a beverage container closed by the lid system, the system comprising:

a plurality of additive compartments, each compartment containing a drink additive;

a lid attachable to a beverage container to close a fill opening of the beverage container, the lid carrying the compartments and comprising:

a drinking port to allow beverage to pass from inside of the container to the mouth of a user, and

an actuator mounted to be sequentially positioned adjacent each additive compartment to allow a user to sequentially dispense the additive from each additive compartment into the beverage container by engaging the actuator with the compartment;

an additive cartridge defining the plurality of additive compartments, the cartridge releasably attached to the lid to allow the cartridge to be carried in the lid and selectively attached and removed from the lid, the additive compartments circumferentially spaced around a central axis;

wherein the actuator is mounted for circumferential movement around the central axis to be sequentially positioned above each of the additive compartments;

the lid further comprises a base mounting the additive compartments;

an actuator carrier mounted to the base for rotation about the central axis to sequentially position the actuator above the additive compartments, the actuator being a plunger mounted in the actuator carrier to translate between a ready position where the actuator does not engage an additive compartment and a dispensing position wherein the actuator engages an additive compartment to dispense the additive therefrom into the beverage container; and

a seal member mounted on one of the actuator carrier and the base, the seal member having a resilient, annular lip for sealing rotational engagement with the other of the actuator carrier and the base.

2. The system of claim 1 wherein the cartridge has a cylindrical beverage passage extending along a central axis, a cylindrical outer wall spaced radially outwardly from the passage, and three walls extending radially between the passage and the outer wall to define the compartments therebetween.

3. The system of claim 1 wherein the lid further comprises a flip top mounted to the actuator carrier for movement between a closed position wherein the flip top covers the drinking port and the actuator and an open position wherein the drinking port and actuator are accessible to a user.

4. The system of claim 1 further including a resilient hood that extends over the actuator.

5. The system of claim 4 wherein the seal member and the resilient hood are part of a unitary resilient component that includes the resilient lip.

6. The system of claim 1 wherein each compartment is closed by a frangible element that is openable by engagement of the actuator with the compartment to dispense the additive.

7. The system of claim 6 , further comprising a rigid element in each compartment extending from a location engageable by the actuator to a location engageable with the frangible element to transmit an opening force from the actuator to the frangible element.

8. The system of claim 6 further comprising a hollow insert in each compartment extending from a location engageable by the actuator to a location engageable with the frangible element to transmit an opening force from the actuator to the frangible element, the insert defining a chamber containing the additive and having an open end facing the frangible element.

9. A drink additive lid system for selectively introducing a drink additive to a beverage container closed by the lid system, the system comprising:

a plurality of circumferentially spaced additive compartments, each compartment containing a drink additive;

a lid attachable to a beverage container to close a fill opening of the beverage container, the lid carrying the compartments and comprising:

a drinking port to allow beverage to pass from inside of the container to the mouth of a user, and

an actuator mounted for circumferential movement to be sequentially positioned adjacent each additive compartment to allow a user to sequentially dispense the additive from each additive compartment into the beverage container by engaging the actuator with the compartment;

a base mounting the additive compartments; and

an actuator carrier mounted to the base for rotation about the central axis to sequentially position the actuator adjacent the additive compartments, the actuator being a plunger mounted in the actuator carrier to translate between a ready position where the actuator does not engage an additive compartment and a dispensing position wherein the actuator engages an additive compartment to dispense the additive therefrom into the beverage container;

wherein the lid further comprises a seal member mounted on one of the actuator carrier and the base, the seal member having a resilient, annular lip for sealing rotational engagement with the other of the actuator carrier and the base.

10. The system of claim 9 wherein the lid further comprises a flip top hinged to the actuator carrier for movement between a closed position wherein the flip top covers the drinking port and the actuator and an open position wherein the drinking port and actuator are accessible to a user.

11. The system of claim 9 wherein the seal member includes a resilient hood that extends over the actuator.

12. The system of claim 11 wherein the seal member and the resilient hood are part of a unitary resilient component that includes the resilient lip.

13. The system of claim 9 wherein each compartment is closed by a frangible element that is openable by engagement of the actuator with the compartment to dispense the additive.

14. The system of claim 13 further comprising a rigid element in each compartment extending from a location engageable by the actuator to a location engageable with the frangible element to transmit an opening force from the actuator to the frangible element.

15. The system of claim 13 further comprising a hollow insert in each compartment extending from a location engageable by the actuator to a location engageable with the frangible element to transmit an opening force from the actuator to the frangible element, the insert defining a chamber containing the additive and having an open end facing the frangible element.
