摘要： A spray dispenser including a hollow casing, having sockets in each of which a pair of O-ring seals is mounted. A ball valve is urged toward one of the O-ring seals of each socket. A housing is removably mounted in the casing. Hollow lugs on the housing each having a cylindrical outer face are received inside O-ring seals in sealing relation therewith. Each lug unseats the associated ball valve. When the housing is removed, the ball valve seats against one O-ring seal when the housing is removed from the casing while the lug is in sealing engagement with the other O-ring seal. Compressed air and liquid under pressure are directed through the sockets to a dispensing valve member on the housing, and the pressure need not be released when the housing is removed.
