Device for dispensing metered quantities of liquid

A device (104) capable of metered dispensing of a liquid is described. The device comprises a first chamber defined by a first cylinder (106) and having a first opening; a second chamber defined by a second cylinder (108) and having a second opening, the second cylinder enclosed within the first cylinder; and a cover member (110) cooperating with the second chamber to define a collection area. In a first state, the first opening and the second opening coincide with each other to define a path for allowing a metered amount of the liquid to flow from a liquid source (102) to the second cylinder for collection in the collection region. In a second state, the second cylinder is movable relative to the first cylinder or vice versa to define a second state in which the first opening and the second opening do not coincide with each other to limit the path. 本发明描述了一种能够计量分配液体的装置(104)。所述装置包括由第一圆筒(106)限定并具有第一开口的第一室；由第二圆筒(108)限定并具有第二开口的第二室，所述第二圆筒封闭在所述第一圆筒内；以及与所述第二室协作以限定收集区域的盖构件(110)。在第一状态中，所述第一开口和所述第二开口彼此重合以限定路径，所述路径用于允许计
