Abstract
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,is depressed, the valve member,, a cover member,and a stem,are moved downwardly to open a valve portion of the stem,and an outer sheath portion,is held in a state in which a protruded portion,thereof is engaged with a protruded portion,of a cover body,. In this state, an end portion of a skirt portion,of a sheath-like responding portion,is closely contacted with a small diameter portion,of an inner circumferential surface of an inner cylinder portion,, and a flow passage defined by a hole portion,, a groove portion,, and an output side hole portion,is closed. Then, the sheath-like responding portion,is moved upwardly by pressure of the content introduced, and the end portion of the skirt,is forced from the small diameter portion,into the large diameter portion,, upon which the end portion is released from the inner circumferential surface of the inner cylindrical portion,and the content flows through the clearance therebetween to the groove,and the output side hole portion,. Reference numeral,designates an ambient air sucking space portion. Such an example is also included that an ejection surface of the output side hole portion,is formed into a tapered shape of 5 to 20 degrees.
