Document Type and Number:
WIPO Patent Application WO1997027000
Kind Code:
A3
Abstract:
A dispenser (10) for dispensing relatively low viscosity material includes a plunger (22) that is movable in a chamber (16) containing the material and a lever (30) that is movable to advance the plunger (32) in the chamber (16). A full stroke of the lever (30) dispenses no more than a single drop of material from the chamber (16). A cap (38) is detachably connected to an outlet (18) of the chamber (16) and includes an arm (44) in contact with the lever when the cap is connected to the outlet for releasably retaining the lever (30) in a fixed position to prevent unintentional discharge of material from the chamber (16). A stop (36) comprising one or more sets of teeth is connected to the lever (30) for hindering advancement of the plunger (22) after the lever (30) is released. In certain embodiments, the dispenser (10) includes two side-by-side chambers (16, 16), and a mixing tray (60) has a well (66) with side recesses (68) for receiving protruding outlets (18, 18) of the chambers (16, 16).
