    • Self-sealing membrane valves can be used with containers where storage between uses is in an upright orientation if the product in the container on the underside of the membrane valve is drained from the membrane valve. This will prevent product droplets from being expelled from the valve as it rapidly opens. In addition, it is useful to have a structure on the exterior of the membrane valve to control the rate of opening of the valve during the dispensing operation. The membrane valve is drained on the underside by use of a plurality of appendages that are adjacent the underside of the valve and by the use of a diaphragm adjacent the upper side of the valve to control the rate of opening of the valve.
    • 如果膜阀下侧的容器中的产品从膜阀排出,则自密封膜阀可以用于容器之间,其中存储物处于垂直取向。 这将防止产品液滴快速打开时从阀门排出。 此外,在膜阀的外部具有结构以在分配操作期间控制阀的打开速度是有用的。 膜阀通过使用邻近阀门下侧的多个附件以及靠近阀门上侧的隔膜来控制阀门的打开速度,在下侧排出。
