Abstract
A meter for a liquid dispenser of the type having an axially movable plunger. The meter includes a housing detachably mountable on the dispenser. The housing has a bore in which is engaged a sleeve on the dispenser. An annular space is provided, coaxially of the bore. In this space is provided a cylindrical actuating member, the base of which is formed as a striker. Upward sliding movement of member actuates hollow plunger so that liquid is dispensed through an aperture. Upward movement of the member also causes an operating member secured to a counter to turn, thereby advancing the counter by one digit. A spring loaded interlocking member is adapted to prevent upward movement of the actuating member if the meter is removed from the dispenser.
