a cap body comprising a space, an upper hole member through a top and communicating with the space of the cap body, a plurality of apertures spaced around the top, the apertures having a diameter less than that of the upper hole member, and a lower through hole communicating with both the space of the cap body and the internal space of the bottle; and
a valve moveably disposed in the cap body and comprising an axial flow channel, a tube disposed through the upper hole member into the space of the cap body, an annular flange extending outward from an outer surface of the tube into the space of the cap body, and a bottom extension extending downward from a joining portion of the tube and the annular flange into the through hole;
wherein the valve is configured to move to a closed position, a spraying position, or an open position relative to the cap body;
wherein in the closed position, the annular flange moves downward away from the apertures to block the through hole, the liquid in the internal space is prevented from flowing into the space of the cap body and the apertures, the axial flow channel is blocked by the bottom extension, and the liquid is prevented from flowing to the axial flow channel;
