Method and apparatus for mixing and dispensing fluids
First Claim

1. A method for dispensing droplets of various materials, comprising:
- arranging a plurality of removable reservoirs for holding the materials to be dispensed;
positioning a reservoir from said removable reservoirs in contact with a dispensing mechanism through a coupling mechanism, said coupling mechanism providing an air tight connection between said material source and said dispensing mechanism;
separating a droplet of the material from said reservoir and placing said droplet into said dispensing mechanism;
accelerating said droplet with said dispensing mechanism; and
expelling said droplet from said dispensing mechanism;
wherein said dispensing mechanism comprises a rod that has at one end a domed shaped tip and at another end a flange termination, and said rod moves in a predetermined reciprocating manner in a tightly fit straight through hole into a body of said dispensing mechanism, and said straight through hole has an open end and an axially perpendicular placed hole into one side of its wall; and
wherein said dispensing mechanism comprises a sealing cup that periodically forms a seal, or moves out of the way in a pre-established timing correlated with the redetermined reciprocating manner of said rod, at said open end of said straight through hole, and a stopper that limits and stops the forward move of said rod during the fluid dispensing process.

Abstract
An apparatus for dispensing and mixing fluids from multiple cartridges into a removable container, based on the user input through the provided interface. The user interface allows viewing and adjusting of the mix to be dispensed prior to the actual dispensing. The apparatus is capable of dispensing fluids that have a wide range of viscosities, and that are sticky or that solidify quickly due to the evaporation of the volatile substances they contain.
