FLUID DISPENSING DEVICE WITH METERED DELIVERY

摘要

The fluid dispensing device ( 10 ) includes a container ( 20 ) with an interior fluid storage region ( 22 ) therein. A flexible metering housing ( 26 ) is disposed in fluid communication with the fluid storage region ( 22 ) a first one-way valve ( 30 ) disposed between the container ( 20 ) and the flexible metering housing ( 26 ). One way flow from the interior fluid storage region ( 22 ) of the container ( 20 ) fills the predetermined volume of the metering chamber ( 32 ) with fluid by vacuum action when a button ( 36 ) is depressed and then released. A second valve ( 40 ) is in fluid communication with the metering housing ( 26 ) and permits one-way fluid flow from the metering chamber ( 32 ) to the exterior outer region of the container ( 20 ) when the metering housing ( 26 ) is depressed again. Each time the metering housing ( 26 ) is depressed a substantially equal volume of fluid ( 24 ) is dispensed from the container ( 20 ). An additional foam layer ( 12 ) on the outside of container ( 20 ) facilitates dispersion and delivery of the fluid ( 24 ).
