    • A valve assembly for a pressurized aerosol-dispensing container, in which a hollow body secured inside the container cooperates with an elongate movable valve member operative from outside the container to dispense a predetermined amount only of the liquid contents of the container for each dispensing operation, avoids problems associated with the formation of gas bubbles by providing a second hollow body as a dip-cup concentrically around the first hollow body and dividing the space between the two hollow bodies into a plurality of capillary channels which retain liquid therein. The two hollow bodies are mutually supporting and the second, outer hollow body may be of plastic material or metal. If of plastic material, it can deform on fitting to grip the inner hollow body; if of metal it can be crimped or otherwise deformed into gripping contact with the inner hollow body.
    • 一种用于加压气溶胶分配容器的阀组件,其中固定在容器内部的中空体与从容器外部操作的细长可移动阀构件配合,以便为每个分配操作仅分配用于容器的液体内容物的预定量, 通过将第二空心体作为浸杯同心地围绕第一中空体提供并将两个空心体之间的空间分成多个保持液体的毛细通道,从而避免与气泡形成相关的问题。 两个中空体相互支撑,第二外部中空体可以是塑料材料或金属。 如果是塑料材质,可以在配件上变形以夹紧内部空心体; 如果是金属,它可以卷曲或以其它方式变形成与内部空心体夹紧接触。
