Abstract: A container lid for a fluid container is formed of a flexible resilient material includes a body member having a drinking aperture and a valve. Upon application of a first force to an actuator region of the body member, the valve unseals the drinking aperture and upon removal of the first amount of pressure, the valve reseals the aperture. Upon the application of a second force to the actuator region that is greater than the first force, the valve engages a locking mechanism and the aperture remains unsealed upon removal of the applied second force. In a second embodiment first and second actuator regions are employed and the application of a force to the second actuator region secures the valve in an unsealed orientation.

Abstract: A lid for use with a fluid container includes a body member and a valve. The body member defines an aperture and includes a central portion that extends to an outer periphery configured to couple to a rim of a fluid container. In one embodiment, the body member and the valve and connected by an interconnecting portion which are formed as an integral single piece structure. The valve has a first portion directly secured to the bottom surface of the body member and a second free end portion that extends from the first portion. The second free end portion includes a protuberance and is movable relative to the first portion between a free state in which the protuberance seals the aperture and a depressed state obtained in response to downward deflection of the central portion of the body member relative to the outer periphery in which the aperture is unsealed.

Abstract: A lid configured for use with a fluid container includes a body member and a valve. The body member includes a central body that extends to an outer periphery configured to couple to a rim of a fluid container. The body member defines an aperture therethrough and has top and bottom surfaces. The valve has a first portion directly secured to the bottom surface and a second portion that extends from the first portion. The second portion includes a protuberance and is movable relative to the first portion between free and depressed states in response to deflection of at least a portion of the central body relative to the outer periphery. The protuberance is configured for sealed engagement with the aperture while the second portion is in the free state and is spaced from the aperture while the second portion is in the depressed state.
