<p>An aerosol type dispenser providing a gas charge mechanism in order to reduce gas charge pressure. The aerosol type dispenser is comprised of a valve stem (11), a seal member (16) separately formed from a housing (14) and a constant stored chamber (14a,14c). The seal member has a cylindrical shape and provides an upper face for receiving gas charge pressure. When the gas is charged from an aperture (12a) between the valve stem and a gasket (12), the seal member shifts to a state apart from the valve stem with gas charge pressure so as to make a passage between the valve stem and the seal member. Since the gas is charged into a container through the passage, gas charge pressure can be reduced. <IMAGE></p> |
