The present invention provides a delayed spray actuator for aerosol which is convenient for a user at the time of an ejection operation, that is simple in the entire construction, and that elongates a delayed time period. When a valve member 1 is depressed, the valve member 1, a cover member 5 and a stem 1 are moved downwardly to open a valve portion of the stem 10 and an outer sheath portion 7 is held in a state in which a protruded portion 7a thereof is engaged with a protruded portion 15c of a cover body 15. In this state, an end portion of a skirt portion 4c of a sheath-like responding portion 4 is closely contacted with a small diameter portion 6b of an inner circumferential surface of an inner cylinder portion 6, and a flow passage defined by a hole portion 6e, a groove portion 4b, and an output side hole portion 2a is closed. Then, the sheath-like responding portion 4 is moved upwardly by pressure of the content introduced, and the end portion of the skirt 4c is forced from the small diameter portion 6b into the large diameter portion 6a, upon which the end portion is released from the inner circumferential surface of the inner cylindrical portion 6 and the content flows through the clearance therebetween to the groove 4b and the output side hole portion 2a. Reference numeral 7d designates an ambient air sucking space portion. Such an example is also included that an ejection surface of the output side hole portion 2a is formed into a tapered shape of 5 to 20 degrees. |
