BEVERAGE CONTAINER CLOSURE WITH VENTING

摘要

A beverage container closure or lid adapted for closing an open end of a beverage container. The lid is 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 opened by pressing a button disposed on a side of the beverage container closure. The stopper is subsequently automatically closed when the button is released. Thus, the 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. The beverage container closure includes an actuating lever configured to press the button when a user applies a force to the lever. By utilizing the mechanical advantage provided by the lever, a user is able to selectively open and close the stopper using a relatively low amount of force.

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 a drinking opening configured to permit fluid passage therethrough when the lid is coupled to the drinking vessel; a stopper movably coupled to the main body and configured for upward displacement into a closed position whereat the stopper engages a portion of the main body and covers the drinking opening to prevent fluid passage therethrough, and downward displacement into an opened position whereat the stopper is spaced apart from the portion of the main body to allow fluid passage through the drinking opening, the stopper having a first cam follower; an actuating member movably coupled to the main body and slidably engaged with the stopper, the actuating member being movable inward and outward, and having a first cam surface, the first cam follower of the stopper being positioned to engage the first cam surface of the actuating member during inward movement of the actuating member to cause the first cam surface to move the first cam follower downward which moves the stopper to the opened position, and being positioned such that during outward movement of the actuating member the first cam surface permits the first cam follower to move upward which moves the stopper to the closed position; and a lever rotatably coupled to the main body and configured for rotatable displacement wherein, when a first force is applied to the lever, the lever is operative to apply a second force to the actuating member to cause the actuating member to move inward.
