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 (l6) and includes an ann (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).

Un distributeur (10) permettant de distribuer un matériau de relativement faible viscosité comprend un piston (22) qui peut se déplacer à l'intérieur d'une chambre (16) contenant le matériau, et un levier (30) qui peut se déplacer de façon à faire avancer le piston (32) à l'intérieur de la chambre (16). Une course complète du levier (30) dispense au maximum une seule goutte de matériau provenant de la chambre (16). Un bouchon (38), relié amovible à un orifice (18) de la chambre (16), comporte un bras (44) en contact avec le levier quand le bouchon est relié à l'orifice, de façon à retenir de manière libérable le levier (30) dans une position fixe pour empêcher la distribution accidentelle de matériau depuis la chambre (16). Une butée (36) comprenant un ou plusieurs ensembles de dents est reliée au levier (30), de façon à empêcher l'avancée du piston (22) une fois que le levier (30) est libéré. Dans certains modes de réalisation, le distributeur (10) comporte deux chambres accolées (16, 16), et un bac mélangeur (60) comporte un puits (66) pourvu d'encoches latérales (68) permettant de recevoir des orifices en saillie (18, 18) des chambres (16, 16).
