A solution is proposed for closing the spout 125 of the container 110 with the liquid 105. Corresponding stopper 135 includes: securing means 315 for securing cap 205 to container 110, delivery port 321 for delivering liquid 105 from container 110, valve member 215 ) Closes the delivery port 321, the valve member 215 in the closed position, the cap suction conduit 339 for sucking air into the container 110 during delivery of the liquid 105, and the liquid ( A connector 327 for connecting to a delivery device 805 of 105, comprising: a cap 205 having a connector 327 in fluid communication with a delivery port 321； Slider suction slidably coupled with cap 205, slider suction for suctioning air into container 110 during delivery of liquid 105, slidably coupled with cap suction conduit 339. A slider 220 having a conduit 440； And a rupturable element 345 for closing the cap suction conduit 339 or the slider suction conduit 440, wherein the stopper 135 is secured with the stopper 135 fixed to the container 110. Under such conditions, the delivery device 805 during its connection is configured to move toward the inside of the container 110, so that the valve member 215 is opened when the valve member 215 opens the delivery port 321. Moving towards the inside of the container to an open position, and moving the slider 220 towards the inside of the container to break the rupturable element 345, thereby causing the slider suction conduit 440 to be in fluid communication with the cap suction conduit 339. Can be.액체(105)가 있는 컨테이너(110)의 주둥이부(125)를 폐쇄하기 위한 해결수단이 제안되어 있다. 대응하는 마개(135)는: 캡(205)을 컨테이너(110)에 고정하기 위한 고정 수단(315), 컨테이너(110)로부터 액체(105)를 전달하기 위한 전달 포트(321), 밸브 부재(215)가 전달 포트(321)를 폐쇄하는 경우에는 폐쇄 포지션에 있는 밸브 부재(215), 액체(105)의 전달 동안 컨테이너(110) 속으로 공기를 흡입하기 위한 캡 흡입 도관(339), 및 액체(105)의 전달 장치(805)에 연결하기 위한 커넥터(327)로서, 전달 포트(321)와 유체 연통되어 있는 커넥터(327)를 가지는 캡(205)； 캡(205)과 슬라이딩가능하게 결합되어 있는 슬라이더(220)로서, 캡 흡입 도관(339)과 슬라이딩가능하게 결합되는, 액체(105)의 전달 동안 컨테이너(110) 속으로 공기를 흡입하기 위한 슬라이더 흡입 도관(440
