Abstract: A device is provided for controlled dispensing of a measured quantity of fluid from a flexible container, The device has a chamber adapted to hold a measured quantity of fluid when the container is inverted and righted. This fluid is then dispensed from the chamber through a conduit in direct response to a force exerted on the flexible wall of the container. One embodiment of the device is particularly suited to safeguard against contamination of the device. This embodiment features a dispensable nozzle ejectable by the user upon administration of the fluid, as well as a valve system to prevent airborne contaminants from entering the device and fluid reservoir. A further embodiment includes an inlet tube having a plurality of measuring notches communicating with a measuring chamber affixed to the side of the device. The inlet tube may be rotated to seal the chamber against spillage of the fluid. An additional embodiment features a floating housing floor slidingly mated within a housing.

Abstract: A viscous fluid dispenser is provided including a housing enclosing a pressurizable viscous fluid reservoir connected to a collapsible measuring chamber. A valve is connected therebetween and can be activated to fill the chamber on demand. The dispenser will discharge a premeasured quantity of fluid either proximally or remotely and direct dispensing of unmeasured quantities without modification.
