Dispenser

Abstract

A dispenser for dispensing materials includes a dispenser body, a driving rod movable relative to the dispenser body and into the receptacle, a trigger lever having an actuation member for displacing the driving rod upon rotation of the trigger lever around a rotation axis, and a pivot member that rotatably connects the trigger lever to the dispenser body and defines the rotation axis. The pivot member is movably connected to the trigger lever such that a lever distance between the rotation axis and the actuation member changes upon movement of the pivot member relative to the trigger lever. The dispenser includes an adjustment mechanism for adjusting a mechanical advantage of the trigger lever by changing the lever distance and to adjustably fix the lever distance to at least a minimum distance and a maximum distance.
