ABSTRACT:
A pistol applicator has a piston handle and a hand hold which are drawn towards each other during application and a piston cylinder housing. An adjustable dose regulating device is provided including a dose regulating wheel fixed to the cylinder housing and rotatable about the longitudinal axis of the cylinder housing and a plurality of notches in the dose regulating wheel each having a different radial extent. An outwardly tapering stepped cross piece is attached to the piston handle and is insertable in one preselected notch at a time, wherein one step of the crosspiece is engageable with the preselected one of the notches upon operating the applicator piston to limit the stroke thereof and thereby regulate the dose applied.
