Abstract
An open top receptacle with a laterally extending handle on one side is arranged to receive a cup-shaped cover. This cover includes a valve assembly to close off an opening in the top of the cover to prevent spilling or splashing of either hot or cold beverages from the receptacle. The valve assembly in turn includes a valve head biased against the opening in the cover by resilient integral supporting arms secured to the underside of the cover. An actuating member passes into one side of the cover at a point spaced 90.degree. from the opening, this point being generally vertically above the lateral handle on the receptacle. With this arrangement, a person can hold the handle of the receptacle in the manner of a mug using the thumb to depress the actuating member inwardly which action moves the valve head away from the opening in the cover to permit drinking of the beverage in the receptacle. Releasing of the actuating member by the thumb permits the resilient supporting arms for the valve head to close off the opening.
