    • PROBLEM TO BE SOLVED: To provide a dispensing closure which ensures liquid tightness even without a cap and is so compact as to be used in perfume bottles or the like, which have a standardized bottle neck diameter.SOLUTION: A dispensing closure 1 for a container that holds a liquid, which can be tightly fitted into a container neck includes a plug body 23 having a central liquid passage and a peripheral air passage, a double-valve diaphragm 22, and a plug cap 21. The double-valve diaphragm 22 comprises a first and a second valve section. The first valve section is a normally closed valve 22d having a slit-type central orifice 22a and seals the central liquid passage of the plug body 23 when in its resting position. The second valve section is a normally closed umbrella-type valve 22b and seals one or more slots of the plug cap 21 when in its resting position.
    • 要解决的问题:提供一种分配闭合件,其即使没有盖也能保持液体密封性,并且如此紧凑地用于具有标准瓶颈直径的香水瓶等。解决方案:用于容器的分配盖1 其保持液体,其可以紧密地装配到容器颈部中,包括具有中央液体通道和周边空气通道的塞体23,双阀隔膜22和塞帽21.双阀隔膜22包括 第一和第二阀部分。 第一阀部分是具有狭缝型中心孔口22a的常闭阀22d,并且当处于其静止位置时密封塞体23的中心液体通道。 第二阀部分为常闭型伞形阀22b,并且在处于其静止位置时密封塞帽21的一个或多个槽。
