VOLUME METERING DISPENSER

摘要

Fluid dispensing assembly to be fit to a container, having a flow configuration and a closed configuration, comprising: a body having a first chamber being in fluid communication with a container engaging portion and an outflow portion, a second chamber being in fluid communication with the outflow portion, and a body wall having a portion that is transparent or translucent such that the level of fluid within the second chamber is visible from outside; a valve, disposed within the body, comprising a seal and a stem attached thereto, the seal selectively engaged to the body at the outflow portion; and a resilient member being elastically deformable attached to the stem opposite of the seal, the valve putting the first and second chambers in fluid communication with one another in the closed configuration, the valve isolating the first chamber from the second chamber in the flow configuration, so that the ratio of fluid flowing out of the these two chambers is fixed.
