A cap with a suction unit includes a cap having a semi-spherical recess defined in a top thereof and communicating with an outlet defined through an inner end of the semi-spherical recess. A first air hole is defined through an inner periphery of the semi-spherical recess. A suction member has a spherical base, which is rotatably engaged with the semi-spherical recess, and a tube extends from the spherical base. A passage is defined through the spherical base and the tube. A second air hole is defined through the spherical base. The passage and the second air hole are respectively in communication with the outlet and the first hole when the suction member is pivoted to a first position, and the passage and the second air hole are respectively not in communication with the outlet and the air hole when the suction member is pivoted to a second position.
