    • A two-part closure assembly for a container includes a spout and a measuring cup. The spout has an outer annular ring, a liquid-dispensing component disposed within an upper portion of the annular ring and a passageway therethrough adapted for fluid flow communication with a liquid held in the container. The annular ring has an inner surface which has an annular groove in the upper portion of the ring, an annular recess in the lower portion of the ring, and means in the lower portion to engage a container. The cup has a base, and a sidewall extending upwardly from the base to define a cavity into which a liquid can be poured. An annular flange, extending outwardly from the outer surface of the sidewall of the cup, is alternately releasably engageable within the annular groove in the inner surface of the annular ring of the spout to envelop the liquid-dispensing component of the spout and within the annular recess in the inner surface to be disposed within the liquid-dispensing component.
    • 用于容器的两部分闭合组件包括喷口和量杯。 喷嘴具有外环形环,设置在环形环的上部内的液体分配部件和适于与保持在容器中的液体流体流动连通的通道。 环形环具有内表面,该内表面在环的上部具有环形槽,在环的下部具有环形凹槽,下部中的装置与容器接合。 杯具有底座和从基座向上延伸的侧壁,以限定一个可以倒出液体的空腔。 从杯的侧壁的外表面向外延伸的环形凸缘交替地可释放地接合在喷口的环形环的内表面中的环形槽内,以包封喷嘴的液体分配部件并且在环形 内表面中的凹槽将被布置在液体分配部件内。
