A pouring device for filling or discharging of a liquid comprising: an elongated body (9), a closure sleeve (4), which is arranged co-axially with respect to the device body (9) and is mounted axially on the main sleeve (1), wherein the main sleeve (1) is slidable relative to the closure sleeve (4) and the body (9) and it comprises an outlet end on its side remote from the body (9) and an inlet end on the side directed to the body (9), facing towards the liquid inlet, wherein at the side of this end the main sleeve (1) has on its side surface at least one, and preferably, at least two outflow openings (1a) or more outflow openings, while a member (2) for activating and shutting off the liquid outflow from the device is located at the outflow end of the device, being characterized in that the member (2) for activating the flow has a form of a push-button (2), located on the main sleeve (1) at its outlet end side, which said push-button (2) is non-rotatably mounted thereon, and between the main sleeve (1) and the closure sleeve (4) the sealing, preferably in the form of a rolling diaphragm (3), as well as the helical spring (5) of the push-button (2) are arranged, the device is transposed to the open flow position by exerting pressure on the pushing member (2) applied in the axial direction and the axial displacement of the push-button member (2).一種用以注入或排出液體之流洩裝置包含長形本體及封閉套筒,後者係與前者共軸並沿軸向安裝於主套筒上。主套筒可相對於封閉套筒及本體而滑動,其遠離本體之一側包含出口端,其朝向本體之一側則包含一面向液體入口之入口端。主套筒入口端側之側邊表面具有至少一個(較佳者為至少兩個)流出開口。一用以開啟及阻斷液體從該裝置流出之元件則位於該裝置之流出端。此元件係一安裝於主套筒出口端側且不可轉動之按鈕,且主套筒與封閉套筒之間配置有滾動膜片及該按鈕之螺旋彈簧。對按鈕施以軸向壓力即可使其軸向位移,並將該裝置移置於暢流位置。1‧‧‧主套筒2‧‧‧按鈕元件3‧‧‧滾動膜片4‧‧‧封閉套筒5‧‧‧彈簧6‧‧‧氣密墊圈9‧‧‧長形本體15‧‧‧導引溝槽16‧‧‧導引突起物17‧‧‧壓力軸套
