Abstract

A lid for a drinking vessel including a lid base, a movable arm, and an actuator. The base defines a drinking opening. The arm is coupled to the base and located in an interior of the base. The actuator is accessible from an exterior of the base. A first and second magnet unit are coupled to one of the arm or actuator. A third magnet unit is coupled to the other of the arm or actuator. The arm is movable between a sealed position, in which the drinking opening is sealed, and an open position, in which the drinking opening is not sealed. The actuator is movable between a first and second position. A magnetic force maintains the arm in the open position while the actuator is in the second position, and a magnetic force maintains the arm in the sealed position while the actuator is in the first position.

First claim

What is claimed is:

1. A lid for a drinking vessel, the lid comprising:
a lid base defining a drinking opening therethrough;
a movable arm coupled to the lid base and located in an interior of the lid base;
a first magnet unit coupled to the movable arm;
an actuator accessible from an exterior of the lid base; and
a second magnet unit coupled to the actuator,
wherein the movable arm is movable between a sealed position, in which the drinking opening is sealed, and an open position, in which the drinking opening is not sealed,
wherein the movable arm is biased toward a biased position, the biased position being one of the sealed position or the open position,
wherein the actuator is movable between a first position and a second position, and
wherein when the actuator is moved to the second position, a repulsive magnetic force between the first magnet unit and the second magnet unit overcomes the bias of the movable arm and causes the movable arm to move away from the biased position.

2. The lid of claim 1 , wherein the movable arm is maintained away from the biased position while the actuator is in the second position, and the movable arm automatically returns to the biased position when the actuator is moved from the second position.

3. The lid of claim 1 , wherein the actuator translates to move to and from the second position, and wherein the movable arm rotates to move between the sealed position and the open position.

4. The lid of claim 1 , wherein the drinking opening extends between a lower volume and an upper volume of the lid base, and
wherein the actuator is isolated from the lower volume and the upper volume of the lid base.

5. A drinking vessel comprising:
the lid of claim 1 ; and
a container, wherein the lid is configured to attach to the container to close an interior volume of the container.

6. A method for sealing and unsealing a drinking opening of a lid, comprising:
pressing an actuator accessible from an exterior of a lid base to move it from a first position to a second position, wherein moving the actuator from the first position to the second position changes a magnetic force on a movable arm within the lid and thereby moves the movable arm to unseal the drinking opening due to one of magnetic attraction or magnetic repulsion; and
moving the actuator from the second position to the first position, wherein moving the actuator from the second position to the first position changes the magnetic force on the movable arm and thereby moves the movable arm to seal the drinking opening due to the other of magnetic attraction or magnetic repulsion,
wherein moving the actuator from the first position to the second position comprises pressing the actuator, and
wherein moving the actuator from the second position to the first position occurs automatically upon releasing the actuator.

7. The method of claim 6 , wherein a magnetic interaction between a first magnet unit coupled to the actuator and a second magnet unit coupled to the movable arm changes the magnetic force on the movable arm.

8. The method of claim 6 , wherein moving the movable arm to seal the drinking opening comprises rotating the movable arm in a first rotational direction about an axis, and wherein moving the movable arm to unseal the drinking opening comprises rotating the movable arm in a second rotational direction about the axis.

9. The method of claim 6 , wherein the drinking opening extends between a lower volume and an upper volume of the lid base,
wherein the movable arm is located within the lower volume of the lid base,
wherein the actuator is located between the lower volume and the upper volume of the lid base, and
wherein the actuator is isolated from the lower volume and the upper volume of the lid base.

10. The lid of claim 1 , wherein the repulsive magnetic force between the first magnet unit and the second magnet unit overcomes the bias of the movable arm and causes the movable arm to move away from the biased position.

11. The lid of claim 2 , wherein a repulsive magnetic force between the first magnet unit and the third magnet unit maintains the movable arm away from the biased position while the actuator is in the second position.

12. The lid of claim 3 , wherein the drinking opening is positioned at a front of the lid, and
wherein the actuator translates horizontally toward the front of the lid to move between the first position and the second position.

13. The lid of claim 1 , wherein the drinking opening is positioned at a front of the lid, and
wherein the actuator can be moved to the second position by pressing a portion of the actuator located at a rear of the lid.

14. The lid of claim 1 , wherein the actuator is biased toward the first position such that the actuator automatically moves from the second position to the first position upon removal of a force holding the actuator in the second position.

15. The lid of claim 1 , wherein the lid base defines an actuator chamber, and the actuator is positioned at least partially within the actuator chamber.

16. The lid of claim 1 , wherein the lid base defines a vent opening therethrough,
wherein when the movable arm is in the sealed position, the vent opening is sealed, and
wherein when the movable arm is in the open position, the vent opening is not sealed.

17. The lid of claim 1 , wherein the movable arm is not mechanically linked to the actuator.

18. The lid of claim 16 , wherein the biased position is the sealed position.

19. The drinking vessel of claim 5 , wherein when the lid is attached to the container, the movable arm is located inside the interior volume of the container, and the actuator is located outside the interior volume of the container.

20. The method of claim 7 , wherein a repulsive magnetic force between the first magnet unit and the second magnet moves the movable arm to unseal the drinking opening when the actuator is moved from the first position to the second position.

21. The lid of claim 1 , wherein the actuator is positioned on the lid base.

22. The method of claim 6 , wherein pressing the actuator to move it from the first position to the second position comprises horizontally translating the actuator.
