Abstract: Disclosed is a cover mountable to a beverage container and mounting method and apparatus thereof. The container cover detachably mountable to an upper surface of a beverage container comprises a body which is formed to have substantially a disc-shaped configuration. The body is partly cut away from an edge toward a center thereof thereby to define a beverage discharging opening which has a predetermined width and a predetermined contour. The beverage discharging opening is capable of being selectively communicated with a discharging hole of the beverage container as the body is rotated. An inner end of the beverage discharging opening is delimited by a rotation guiding part which has a predetermined curvature to guide rotation of the body. The body has a straw insertion hole which is defined therein at a predetermined location to have a predetermined diameter in a manner such that a straw can be inserted therethrough.
