Claim:
A cup assembly comprising: a cup having an inner wall formed on an interior of the cup to sandwich a first chamber with an outer periphery of the cup, the inner wall having a first cup cutout defined in a peripheral edge of the inner wall; and a lid being able to be mounted on top of the cup to close an open end of the cup, the lid having an inner extension extending from a bottom face of the lid to sandwich a second chamber with an outer wall which is extended from a peripheral edge of the lid, the lid having an outlet defined through the lid to communicate with the second chamber, the inner extension having a first lid cutout defined in a peripheral edge of the inner extension to correspond to and selectively align with the first cup cutout of the cup and a second lid cutout defined in the peripheral edge of the inner extension to correspond to the peripheral edge of the inner extension; wherein a first passage including the first cup cutout of the cup and the first lid cutout of the lid and in communication with the outlet is defined after the lid is mounted on top of the cup; a second passage including the second lid cutout of the lid is defined after the lid is mounted on top of the cup; and a liquid cooling compartment including the first chamber and the second chamber is formed after the lid is mounted on top of the cup such that tilting the cup assembly enables the liquid cooling compartment to be filled with liquid contained in the cup when the second passage is in communication with the liquid cooling compartment and the first lid cutout of the lid is in misalignment with the first cup cutout of the cup via rotation of the lid relative to the cup thereby allowing the liquid to flow out of the outlet after communication between the first lid cutout and the first cup cutout is established via the rotation of the lid after temperature of the liquid in the liquid cooling compartment has cooled.
