PROBLEM TO BE SOLVED: To provide an actuator of a simple valve mechanism and an ejection container of a simple pumping mechanism with the mounted actuator. SOLUTION: This actuator is of such a construction that a flexible film member 6 is partially bonded covering a through hole 2 which penetrates vertically through an actuator body 1 and the part where the film member 6 is unbonded communicates with the through hole 2 and further, the end part of the film member 6 constitutes a duct which serves as an automatic opening/ closing ejection aperture 7, with a groove 5 which communicates with the through hole 2 and extends to a spot neat the ejection aperture 7, formed on the upper face of the actuator body 1 inside the duct 8. Further, the discharge container body T is constituted of an outer container 10, an inner container 25 with a cylindrical bag member 30, and a lid-like elastic element 15 which has a flexible dome part 17 having a steam 16 formed upright and also has an inset partition member 20 having a mounted valve body 22. In addition, the actuator is mounted on the stem 16 to form a pumping chamber 23 inside the dome part 17 to complete the ejection container. |
