Metered dispensing device

A dispensing device having a first member connectable to a container which has a passage. A second member is movably connectable to the first member. A registration mechanism reflects a first position and a second position as the members are moved relative to each other. The first member has a mixing chamber, with one or more capillaries, and an opening; each in communication with the passage of the container. The second member has a dispensing chamber, to hold Fluid-1 for dispensement, and an outlet. In the first position, the outlet is in discharge communication with the opening permitting discharge from the outlet of Fluid-2 in the container. During relative movement when the device is between the first and second positions, the outlet is sealed from the opening and the capillaries, and the dispensing chamber passes over the mixing chamber depositing Fluid-1 into the mixing chamber. In the second position the mixing chamber is in discharge communication with the outlet permitting Fluid-2 from the container to pass through the mixing chamber, mix with Fluid-2, and exit the outlet co-mixed.
