    • A plug device for a liquid container is presented to enable cleaning of a flow passage of the liquid container as well as to eliminate the liquid being left in the flow passage during the operation of the liquid container, thus providing hygienic and safe operation of the container. The plug device consists of an outer plug member and an inner plug member which is detachably attached to the outer plug member. When the members are assembled, a flow passage is formed automatically to enable access to the liquid stored in the container. When a press button provided on the inner plug member is pressed down, the opening disposed at the bottom of a plunger device remains open, resulting in the interior space of the container being connected with the flow passage via the internal liquid passage. In this condition, the container can be tilted to dispense the liquid from the container. When the dispensation is completed, and the container is uprighted, the liquid in the flow passage is returned to the interior space of the container via a tapered surface formed on the inner plug member, thus leaving no liquid in the flow path. The plunger device is operated again to close off the opening, and thereby offering safe operation and enabling to maintain the quality of the liquid stored in the container, by removing a potential source of contamination from the residual liquid.
    • 提供一种用于液体容器的塞子装置,以便清洁液体容器的流动通道,并且在液体容器的操作期间消除在流动通道中残留的液体,从而提供容器的卫生且安全的操作 。 插头装置包括外插头构件和可拆卸地附接到外插头构件的内插头构件。 当构件组装时,自动地形成流动通道以使得能够进入存储在容器中的液体。 当设置在内塞构件上的按钮被按压时,设置在柱塞装置底部的开口保持打开,导致容器的内部空间经由内部液体通道与流动通道连接。 在这种情况下,容器可以倾斜以从容器中分配液体。 当分配完成并且容器竖立时,流动通道中的液体经由形成在内塞构件上的锥形表面返回到容器的内部空间,从而在流路中不留下液体。 再次操作柱塞装置以关闭开口,从而通过从残留液体中除去潜在的污染源,从而提供安全操作并且能够保持储存在容器中的液体的质量。
