ABSTRACT:
A dispenser for dispensing relatively low viscosity material includes a plunger that is movable to advance the plunger in the chamber. A full stroke of the lever dispenses no more than a single drop of material from the chamber. A cap is detachably connected to an outlet of the chamber and includes an arm in contact with the lever when the cap is connected to the outlet for releasably retaining the lever in a fixed position to prevent unintentional discharge of material from the chamber. A stop comprising one or more sets of teeth is connected to the lever for hindering advancement of the plunger after the lever is released. In certain embodiments, the dispenser includes two side-by-side chambers, and a mixing tray has a well with side recesses for receiving protruding outlets of the chambers.
