Abstract

A beverage container closure or lid that is adapted for closing an open end of a beverage container. The lid is selectively couplable to the beverage container and includes a selectively openable stopper that when closed, creates a fluid-tight seal between the beverage container and the environment. The stopper may be selectively opened by a user by the user pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the user releases the button. Thus, a user may open and close the beverage container closure using a single hand without the need to remove the beverage container closure from the beverage container.

First claim

The invention claimed is:

1. A lid for use with a drinking vessel containing a liquid, comprising:
a main body selectively couplable to the drinking vessel, the main body including an upper portion having an opening configured to permit fluid passage therethrough when the lid is coupled to the drinking vessel and a main body sidewall extending downward and defining a hollow interior body region below the upper portion of the main body;
a stopper positioned at least partially within the hollow interior body region, the stopper having a stopper sealing portion, a fluid flow barrier portion spanning across the hollow interior body region and a perimeter sidewall along an outer perimeter of the barrier portion, the perimeter sidewall being located adjacent to the main body sidewall, the stopper being configured for upward displacement into a closed position whereat the stopper sealing portion sealingly engages the upper portion of the main body at the opening to prevent fluid passage therethrough, and downward displacement into an opened position whereat the stopper sealing portion is spaced apart from the opening to allow fluid passage through the opening, the perimeter sidewall being spaced inward of the main body sidewall to form a perimeter fluid flow pathway located between the perimeter sidewall and the main body sidewall, the perimeter fluid flow being maintained when the stopper is in the closed position, the perimeter sidewall being positioned at least partially within the hollow interior body region and spaced apart from the main body sidewall along at least a portion of the perimeter sidewall during the entire travel of the stopper between the opened position and the closed position, the stopper further including at least one spacer portion spacing the perimeter sidewall apart from the main body sidewall, the at least one spacer portion configured to slidably engage the main body sidewall as the stopper moves between the opened position and the closed position to maintain the perimeter fluid flow pathway open during the entire travel of the stopper between the opened position and the closed position, the stopper having an engagement portion comprising one of a cam and a cam follower; and
an actuating member movably coupled to the main body, the actuating member being inwardly movable and having an engagement portion comprising the other of the cam and the cam follower, the engagement portion of the actuating member arranged to engage the engagement member of the stopper and apply a downwardly directed operating force to the engagement portion of the stopper during inward movement of the actuating member to cause the engagement portion of the actuating member to move the engagement portion of the stopper downward and thereby move the stopper to the opened position.

2. The lid of claim 1 , wherein the actuating member is outwardly movable, the engagement portion of the actuating member is positioned during outward movement of the actuating member such that the engagement portion of the actuating member permits the engagement portion of the stopper to move upward which moves the stopper to the closed position.

3. The lid of claim 1 , wherein when the stopper is in the closed position the stopper sealing portion engages the upper portion of the main body and covers the opening to seal the opening, and when the stopper is in the opened position the stopper sealing portion is spaced away from the upper portion of the main body and uncovers the opening to unseal the opening.

4. The lid of claim 1 , wherein the perimeter sidewall is immediately adjacent to the main body sidewall.

5. The lid of claim 1 , wherein the at least one spacer portion includes a plurality of spacers positioned to maintain the perimeter sidewall spaced apart from the main body sidewall as the stopper moves between the opened position and the closed position to maintain the perimeter fluid flow pathway open during the entire travel of the stopper between the opened position and the closed position.

6. The lid of claim 5 , wherein the spacers slidably engage one of the main body sidewall and the perimeter sidewall as the stopper moves between the opened position and the closed position.

7. The lid of claim 1 , wherein the at least one spacer portion is positioned to limit movement of the stopper toward the main body sidewall to maintain the perimeter fluid flow pathway during the entire travel of the stopper sealing portion between the opened position and the closed position.

8. The lid of claim 1 , wherein the perimeter sidewall is downwardly extending along the full outer perimeter of the barrier portion.

9. The lid of claim 1 , wherein the perimeter sidewall extends fully about the outer perimeter of the barrier portion and is located immediately adjacent to the main body sidewall along a full perimeter length of the outer perimeter of the barrier portion, the outer perimeter of the barrier portion being spaced inward of the main body sidewall at a distance to form the perimeter fluid flow pathway extending fully about the outer perimeter of the barrier portion and being located immediately adjacent to the main body sidewall along the full perimeter length of the outer perimeter of the barrier portion during the entire travel of the stopper between the opened position and the closed position.

10. A lid for use with a drinking vessel containing a liquid, comprising:
a main body selectively couplable to the drinking vessel, the main body including an upper portion having an opening configured to permit fluid passage therethrough when the lid is coupled to the drinking vessel and a main body sidewall extending downward and defining a hollow interior body region below the upper portion of the main body;
a stopper positioned at least partially within the hollow interior body region, the stopper having a stopper sealing portion, a fluid flow barrier portion spanning across the hollow interior body region and a perimeter sidewall along an outer perimeter of the barrier portion, the perimeter sidewall being located adjacent to the main body sidewall, the stopper being configured for upward displacement into a closed position whereat the stopper sealing portion sealingly engages the upper portion of the main body at the opening to prevent fluid passage therethrough, and downward displacement into an opened position whereat the stopper sealing portion is spaced apart from the opening to allow fluid passage through the opening, the perimeter sidewall being spaced inward of the main body sidewall to form a perimeter fluid flow pathway located between the perimeter sidewall and the main body sidewall, the perimeter fluid flow being maintained when the stopper is in the closed position, the perimeter sidewall being positioned at least partially within the hollow interior body region and spaced apart from the main body sidewall along at least a portion of the perimeter sidewall during the entire travel of the stopper between the opened position and the closed position, the stopper further including a stopper sealing portion support extending upward above the barrier portion with the stopper sealing portion located atop the stopper sealing portion support to position the stopper sealing portion above a stopper engagement portion during the entire travel of the stopper between the opened and closed positions and to align the stopper sealing portion with the opening when the stopper is in the closed position, the stopper sealing portion support being laterally offset from a central axis of the main body, the stopper engagement portion comprising one of a cam and a cam follower; and
an actuating member movably coupled to the main body, the actuating member being inwardly movable and
