Abstract: An improved plugging system for a liquid container (31) comprises an inner plug (3) and an outer plug (1), an opening/closing member 8, and pressure adjusting springs (9, 9') which apply elastic force to the opening/closing member (8) against the inner plug (3). A push button (131) is mounted in the center of the plugging system and has a rib (132) which is downwardly extended and coupled to the opening/closing member (8). In a closed state of the plugging system, a shoulder portion (135) of an opening/closing button (133) is caught by the rib (132). While in an opening state, as the opening closing button (133) is pushed outwardly, the rib (132) is pushed downwardly and a moving rail portion (134) slides on the rib (132) since the shoulder portion (135) is released from the rib (132) thereby opening the discharge path (4).

Abstract: A fluid container plug is disclosed in which, if a button of the plug is pressed, the content of the container can be discharged by inclining the container, and if another button is pressed, the container is locked shut, so that the container can be manipulated in a one touch manner, thereby making the use of the container convenient. The fluid container plug according to the present invention includes an outer casing with its upper and lower ends open, an inner casing installed within the outer casing keeping a gap with the outer casing; a discharge path formed through the lower open portion of the outer casing and along the gap through which the content of the container is discharged. An opening/closing member is installed within the inner casing in a reciprocating manner to open and close the lower opening portion of the outer casing.
