Cup

The utility model belongs to the technical field of cups and aims to provide a cup. The cup comprises a cup body, a screw cap detachably connected with the cup body and an elastic leakage-proof valve detachably connected to the screw cap. A plurality of liquid outlets are formed in a clamping portion of the leakage-proof valve, the clamping portion butts against a stop portion of the screw cap, and the stop portion can seal all the liquid outlets at the same time so as to block liquid in the cup body from leaking out; meanwhile, a connecting portion of the leakage-proof valve is penetratingly arranged in an annular hole formed by enclosing of the stop portion, and no leakage of liquid in the cup body is further ensured as the outer peripheral wall of the connecting portion clings to the peripheral wall of the annular hole; besides, when a drinker drinks, after a contact portion of the leakage-proof valve is stressed, the connecting portion and the clamping portion are deformed so as to allow the liquid in the cup body to flow out; since the liquid outlets are arranged annularly, deformation of the leakage-proof valve is changed adaptively with stress size, and the cup is capable of realizing omni-directional drinking and convenient for timely control on drinking flow.
