PURPOSE:To make surer a sealing function against the outside space and simplify the construction of a seal to facilitate the manufacturing thereof. CONSTITUTION:A housing 2 wherein a hole 6 for introducing discharging gas in the upper section 1a in a body 1 of a container is provided downstream of an opening 3 for admitting contents stored in the lower section of the body 1 and a stem 7 which releases a closing action having been effected by a stem rubber 5 (first valve member), following the movement of the stem to a use mode position, are provided. Thus, a second valve member 9 is provided to open or close the hole 3 corresponding to the movement of the stem 7, and when the stem 7 returns from the use mode position to a nonuse potition, the stem rubber 5 is closed a predetermined period of time past the action of the valve member 9, so that residue in a discharge passage 7a is discharged to the outside by the flow of the discharging gas for the predetermined period of time. |
