    • 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).
    • 用于分配相对低粘度材料的分配器(10)包括可在容纳材料的腔室(16)中移动的柱塞(22)和可移动以将柱塞(32)推进到腔室(16)中的杆(30) )。 杠杆(30)的整个行程从腔室(16)中分配不超过一滴物料。 盖(38)可拆卸地连接到腔室(16)的出口(18),并且当盖子连接到出口以可释放地将杠杆(30)保持在一个位置时,包括与杠杆接触的臂(44) 固定位置以防止材料从腔室(16)的无意排放。 包括一组或多组齿的止动件(36)连接到杠杆(30),用于在杠杆(30)被释放之后妨碍柱塞(22)的前进。 在某些实施例中,分配器(10)包括两个并排室(16,16),并且混合盘(60)具有井(66),其具有侧凹槽(68),用于接收突出的出口 )的腔室(16,16)。
