摘要：
A closure device capable of dispensing a metered amount of liquid into a container during a closing action and capable of doing so for several successive closing actions. The closure device comprises a cap wall (3), a deformable reservoir (5) capable of being filled with a liquid and a rigid plate (4) with one or more perforations (6). Upon closure the deformable reservoir is compressed by being squeezed between the rigid plate and the cap wall. The invention further relates of use of such a closure device to prolong the open shelf-life of spoilage-sensitive contents held by a container.
