BEVERAGE CONTAINER CLOSURE

摘要

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.

主权项

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 positionable at least partially within the hollow interior body region, the stopper having a stopper base portion and a stopper sealing portion, the stopper base portion having a fluid flow barrier portion spanning across the hollow interior body region with a barrier portion outer edge located adjacent to the main body sidewall, the stopper being configured for upward displacement of the stopper sealing portion 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 barrier portion outer edge being spaced inward of the main body sidewall to form a perimeter fluid flow pathway located outward of the barrier portion outer edge and adjacent to the main body sidewall, the perimeter fluid flow being maintained when the stopper sealing portion is in 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 sealing to the opened position.
