A valved dispenser cartridge is supported within a housing which is adapted to be mounted to a door or other support. A portion of the valve stem extends above the cartridge and is connected to and is operated by a spray button. The spray button is a captive component of the housing and is retainably mounted thereto for only sliding, non-tilt motion in response to forces applied by either an actuator means or the valve stem. The actuator means responds to relative motion between the support and adjacent external structures, which motion is thereby converted into an axial movement of the spray button to dispense product followed by the immediate release of the spray button permitting it and the valve stem, which is spring loaded, to return upwardly to their normal non-dispensing position. The actuating means is preferably single-acting, utilizing a carriage to move a pivotable pawl which in the cocked position cams on and depresses the spray button when the carriage moves in one direction under the action of the external forces and which in the trail position passes over and avoids depressing the spray button when the carriage moves in the return direction under the action of a spring. A mechanism positively cocks the pawl prior to the next actuating stroke. A cover to close the housing is also provided. When the dispenser cartridge is emptied, it alone is removed, discarded and replaced.
