ABSTRACT:
A travel lid for a disposable coffee cup useful in place for drinking coffee while the user is moving. The lid has a continuous rim adapted to grip the upper rim of a disposable coffee cup and a top closing surface. On one side of the closing surface there is an expansible coffee-sipping port element shaped and positioned to be received by the mouth. On the opposite side of the closing surface there is a vent formation. The expansible coffee sipping port element, in the condition supplied to the server of coffee, is of vertically collapsed configuration with its upper end disposed below the upper edge of the continuous rim. The sipping port element in the collapsed position provides clearance sufficient to enable the lid to be compactly stacked with other lids of identical form for shipment and dispensing. The expansible sipping port element is constructed to respond to an outward pulling action to extend above the rim to a position exposed for contact with the mouth, enabling coffee to be sipped therefrom upon tipping of the cup. The vent is disposed sufficiently away from the center of the top closing surface in the direction opposite from the coffee sipping port to prevent coffee spillage therethrough during drinking from the coffee sipping port element. The coffee sipping port element is sized and shaped to enable gradual flow of coffee therethrough upon tipping of the coffee cup to which it is attached.
