PURPOSE: A stopper is provided to offer supply of fluid by not separating from a container while easily discharge contained fluid by making bottom up. CONSTITUTION: A main body unit(10) includes a container engagement unit(11) having a female screw thread is being formed to engage with a male screw formed in an inlet of a container, a guide unit(13) having a fluid path(14) being formed in the longitudinal direction for discharging fluid and a connection unit closing between the container engagement unit and guide unit. A fluid inflow and outflow unit(20) includes a blocking unit(21) being formed to cover one end of the guide unit, a slide unit(23) having a passage hole being formed to pass a fluid and a switching unit(25) being connected with the slide unit to make the blocking unit be separated from the guide unit. A spring(30) is connected with the connection unit and the switching unit so that the blocking unit is closely attached to the guide unit by recovering the switching unit when pressure to the front-end of the switching unit is applied. The switching unit includes a water storage space with a relatively large diameter compared to the slide unit so that supplied fluid flows to the slide unit while being stored. A male screw is formed in the outer periphery of the switching unit to engage with the container engagement of the other main body unit. The main body unit further includes a cover(17) having a penetration hole(17a) formed to discharge fluid while covering the switching unit by being extended to have the same diameter with the container engagement unit.
