Abstract
A dispensing container which stores two or more separated fluids and blends the fluids when dispensing. The container includes a storage bottle for containing the first fluid and an interior auxiliary vessel for containing a second fluid. The auxiliary vessel is configured as a closure closing the open storage area of the storage bottle by threading thereto, and forms a mixing chamber above the storage bottle and auxiliary vessel. The mixing chamber has first check valves preventing backflow into the storage area of the bottle and second check valves preventing backflow into the auxiliary vessel. Preferably, the check valves are flaccid membrane valves. Optionally, agitating balls are provided in the mixing chamber. In another option, squeeze resistant compression members are placed inside the storage bottle to transfer pressure from squeezing to the interior auxiliary vessel. In still another option, dispensing container has at least one and optionally several recharging vessels. The storage bottle and interior auxiliary vessel have alignable ports enabling the latter to be recharged by a recharging vessel, which has a nozzle which penetrates the aligned ports.
