A lid has an outer ring, an inner ring integrally formed with the outer ring and a hollow central ring integrally formed with the inner ring and having an inner diameter larger than that of an outer diameter of the tube so that the tube is able to extend into the hollow central ring and be securely received therein and a securing mechanism integrally formed with the inner ring. ## Claims ### Claim 1 A lid module adapted to cover a top opening of a cup body, the lid module comprising: a plug device movably and expandably received inside an inner ring to adapt to an inner periphery of a cup body, wherein the plug device includes a plug with a tube and spaced leaves integrally extending out from a bottom of the tube and selectively expandable relative to the tube so that the lid module is able to have a water tight engagement with the inner periphery of the cup body when the plug device is in an expanded status and the lid module is freely movable relative to the cup body when the plug device is in a contracted status a lid having an outer ring, the inner ring integrally formed with the outer ring, and a hollow central ring integrally formed with the inner ring and having an inner diameter larger than that of an outer diameter of the tube so that the tube is able to extend into the hollow central ring and be securely received therein and a securing mechanism integrally formed with the inner ring. ### Claim 2 (depends on 1) The lid module as claimed in claim 1, wherein the inner ring has a first fixing device formed on an inner periphery thereof and the plug has a second fixing device formed on an outer periphery thereof to correspond to the first fixing device such that the plug is securely yet movably received inside the inner tube after the first fixing device is connected to the second fixing device. ### Claim 3 (depends on 2) The lid module as claimed in claim 2 further comprising a stop removable yet partially and securely received inside the central ring, the stop having a stopping shoulder formed on an outer periphery thereof to abut against a bottom most end of the stop to prevent the plug from escaping from the lid. ### Claim 4 (depends on 1) The lid module as claimed in claim 1, wherein each of the leaves has a rib formed on a side face of each of the leaves, the inner tube has a tapered bottom end face corresponding to the rib such that when the plug is movable relative to the inner tube, engagement between the tapered bottom end face and the ribs forces the leaves to expand outward relative to the tube. ### Claim 5 (depends on 4) The lid module as claimed in claim 4 further comprising a stop removable yet partially and securely received inside the central ring, the stop having a stopping shoulder formed on an outer periphery thereof to abut against a bottom most end of the stop to prevent the plug from escaping from the lid. ### Claim 6 (depends on 1) The lid module as claimed in claim 1, wherein each of the leaves has an annular boss formed on the other side face of each of the leaves to increase engagement with the seal. ### Claim 7 (depends on 1) The lid module as claimed in claim 1, wherein the lid further has a central column having a top portion provided with a first threading formed on an outer periphery thereof to correspond to a first fixing device formed on an inner periphery of the tube and a bottom portion integrally formed with the top portion and having a diameter smaller than that of the top portion, the bottom portion having a second threading formed on an outer periphery thereof, a stop removably received inside the inner ring and having a second fixing device formed on an inner periphery thereof to correspond to the second threading of the central column so that when the second fixing device is connected to the second threading, the stop is securely received inside the inner ring. ### Claim 8 (depends on 7) The lid module as claimed in claim 7 further comprising a seal mounted around an outer periphery of the leaves so that when the leaves are expanded, the seal is expanded to adapt to the inner periphery of the cup body and the plug together with the seal is able to selectively have a water tight engagement with the inner periphery of the cup body. ### Claim 9 (depends on 8) The lid module as claimed in claim 8, wherein each of the leaves has a rib formed on one side face of each of the leaves, the inner tube has a tapered bottom end face corresponding to the rib such that when the plug is movable relative to the inner tube, engagement between the tapered bottom end face and the ribs forces the leaves to expand outward relative to the tube. ### Claim 10 (depends on 9) The lid module as claimed in claim 9, wherein each of the leaves has an annular boss formed on the other side face thereof such that when the seal is mounted around the outer periphery of the leaves, engagement between the seal and the leaves increases.
