  • Method for inserting an additive liquid into a flowing fluid and discharging the resultant mixture
    Patent number: 4244494
    Abstract: A dispensing assembly for discharging a flowing fluid into which a desired amount of an additive liquid has been inserted includes a container for the additive liquid which may be removed from a dispenser body. The container is normally positively biased to a closed condition to prevent escape of the additive liquid. Opening of the container is effected upon establishment of a predetermined minimum pressure by the flowing fluid in the dispenser body. Additive liquid is forced from the container into the flowing fluid by a metered amount of flowing fluid inserted into the container to cause a flexible pressure member to force the additive liquid from the container. Opening of the container is not achieved until after the pressure member is exerting a force on the additive liquid.
