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.
