Abstract

A lid for a container including a lid body, a movable arm, a first magnet unit coupled to the movable arm, an actuator, and a second magnet unit coupled to the actuator. The actuator is movable between a first and second position. The movable arm is movable between a sealing position, in which a drinking opening of the lid body is sealed, and an open position, in which the drinking opening is not sealed. When the actuator is in the first position, at least one of a biasing force and an attractive magnetic force between the first and second magnet units hold the movable arm in the sealing position. When the actuator is moved toward the second position, a repulsive magnetic force between the first and second magnet units causes the movable arm to move toward the open position.

First claim

What is claimed is:

1 . A lid for a container, the lid comprising:
a lid body defining a drinking opening therethrough; a movable arm coupled to the lid body and located in an interior of the lid body, a sealing arm movably coupled to the movable arm, wherein the movable arm is movable between a sealing position, in which the sealing arm seals the drinking opening, and an open position, in which the drinking opening is not sealed; a first magnet unit coupled to the movable arm; an actuator accessible from an exterior of the lid body, the actuator movable between a first position and a second position; and a second magnet unit coupled to the actuator, wherein when the actuator is in the first position, at least one of a biasing force and an attractive magnetic force between the first magnet unit and the second magnet unit hold the movable arm in the sealing position, and wherein when the actuator is moved toward the second position, a repulsive magnetic force between the first magnet unit and the second magnet unit causes the movable arm to move toward the open position.

2 . The lid of claim 1 , wherein the lid body defines a vent opening, and
wherein the drinking opening and the vent opening are the only openings through the lid body.

3 . The lid of claim 1 , where no mechanism for sealing or unsealing the drinking opening penetrates the lid body.

4 . The lid of claim 1 , wherein the movable arm is biased toward the sealing position by the biasing force, and
wherein a spring provides the biasing force.

5 . The lid of claim 1 , wherein the actuator automatically moves from the second position to the first position upon removal of a force holding the actuator in the second position.

6 . The lid of claim 1 , wherein when the actuator is moved from the second position to the first position, the repulsive magnetic force between the first magnet unit and the second magnet unit is reduced, and the movable arm returns to the sealing position.

7 . The lid of claim 1 , wherein the movable arm pivots about a rotation axis when moving from the sealing position to the open position.

8 . The lid of claim 7 , wherein the first magnet unit and the second magnet unit are both located to the same side of a vertical plane passing through the rotation axis of the movable arm.

9 . The lid of claim 1 , wherein the lid body defines a venting opening therethrough,
wherein when the movable arm is in the sealing position, the venting opening and the drinking opening are sealed, wherein when the movable arm is in the venting position, the venting opening is not sealed and the drinking opening is sealed, and wherein when the movable arm is in the open position, the venting opening and the drinking opening are not sealed.

10 . The lid of claim 1 , wherein the actuator linearly slides along a travel axis to move between the first position and the second position, and
wherein one of the first magnet unit or the second magnet unit is angled relative to the travel axis.

11 . The lid of claim 10 , wherein both the first magnet unit and the second magnet unit are angled relative to the travel axis.

12 . The lid of claim 11 , wherein the one of the first magnet unit or the second magnet unit is angled between 2 and 20 degrees relative to the travel axis.

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

14 . The lid of claim 1 , wherein the sealing arm is pivotable and slidable relative to the movable arm.

15 . A lid for a container, the lid comprising:
a lid body defining a drinking opening and a venting opening therethrough; a movable arm coupled to the lid body and located in an interior of the lid body, the movable arm movable between a sealing position, a venting position, and an open position; a first magnet unit coupled to the movable arm; an actuator accessible from an exterior of the lid body, the actuator movable between a first position and a second position; and a second magnet unit coupled to the actuator, wherein when the movable arm is in the sealing position, the venting opening and the drinking opening are sealed, wherein when the movable arm is in the venting position, the venting opening is not sealed and the drinking opening is sealed, wherein when the movable arm is in the open position, the venting opening and the drinking opening are not sealed, and wherein in response to the actuator moving from the first position to the second position, a magnetic force between the first magnet unit and the second magnet unit moves the movable arm from the sealing position to the venting position and then to the open position.

16 . The lid of claim 15 , wherein the actuator remains in the second position while the movable arm moves from the venting position to the open position.

17 . The lid of claim 15 , further comprising a sealing arm movably coupled to the movable arm and movable between a sealing position, in which the sealing arm seals the drinking opening, and an open position, in which the sealing arm does not seal the drinking opening.

18 . The lid of claim 17 , wherein:
when the movable arm is in the sealing position, the movable arm seals the venting opening and the sealing arm seals the drinking opening, and when the movable arm is in the venting position, the sealing arm seals the drinking opening.

19 . The lid of claim 17 , wherein in response to the movable arm moving to its open position, the sealing arm moves to its open position.

20 . The lid of claim 17 , wherein the movable arm defines a slot, and the sealing arm comprises a pin slidable within the slot of the movable arm.

21 . The lid of claim 20 , wherein the pin of the sealing arm pivots within the slot when the movable arm moves from the venting position to its open position, and
wherein the pin of the sealing arm slides within the slot when the movable arm moves from its sealing position to the venting position.

22 . The lid of claim 17 , further comprising a drinking spout in fluid communication with the drinking opening,
wherein the sealing arm seals the drinking opening inside the drinking spout.

23 . The lid of claim 15 , wherein the actuator linearly slides along a travel axis to move between the first position and the second position, and
wherein one of the first magnet unit or the second magnet unit is angled relative to the travel axis.

24 . A container comprising:
the lid of claim 15 ; and a vessel, wherein the lid is configured to attach to the vessel to close an interior volume of the vessel.

25 . A lid for a container, the lid comprising:
a lid body defining a drinking opening therethrough; a movable arm coupled to the lid body and located in an interior of the lid body, the movable arm movable between a sealing position, in which the drinking opening is sealed, and an open position, in which the drinking opening is not sealed; a first magnet unit coupled to the movable arm; an actuator accessible from an exterior of the lid body, the actuator linearly slidable along a travel axis from a first position to a second position; and a second magnet unit coupled to the actuator, wherein when the actuator is moved toward the second position, a force between the first magnet unit and the second magnet unit causes the movable arm to move away from t
