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.

Claims

1. An apparatus for mixing and dispensing fluids, the apparatus comprising:

a dispensing mechanism having a rod that has at one end a pointy dispensing tip and at the other end a flange termination, and said rod moves in a predetermined reciprocating manner in a tightly fit straight through hole into the 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;

a sealing cup that can periodically form a seal, or move out of the way in a pre-established timing correlated with the predetermined reciprocating manner of said rod, at said open end of said straight through hole;

a stopper that limits and stops the forward move of said rod during the fluid dispensing process;

one or more actuators;

a user interface;

a microcontroller unit that includes a non-volatile memory for storing the program code and look-up tables;

one or more removable reservoirs for holding the materials to be dispersed and that can be positioned and connected with said dispensing mechanism;

a removable mixing container; and

a coupling mechanism that can make an air tight connection between said reservoir and said dispensing mechanism.

2. The apparatus of claim 1, wherein said reservoirs contain cosmetic substances or bio-medical substances.

3. An apparatus for mixing and dispensing fluids, the apparatus comprising:

a dispensing mechanism having a rod that has at one end a pointy dispensing tip and at the other end a flange termination, and said rod moves in a predetermined reciprocating manner in a tightly fit straight through hole into the 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;

a sealing cup that can periodically form a seal, or move out of the way in a pre-established timing correlated with the predetermined reciprocating manner of said rod, at said open end of said straight through hole;

a stopper that limits and stops the forward move of said rod during the fluid dispensing process;

one or more actuators;

a user interface;

a microcontroller unit that includes a non-volatile memory for storing the program code and look-up tables;

one or more removable reservoirs that can be positioned and connected with said dispensing mechanism, and said reservoirs each comprising;

a cavity substantially defined by the walls of said removable reservoir, the fluid to be dispensed, an impermeable to air and flexible membrane located inside said cavity and said flexible membrane encompassing and separating said fluid from the air, a normally closed valve leading to the contained fluid and said normally closed valve opening only during dispensing, and an opening in said walls of said removable reservoir where said opening allows surrounding air to reach the outside of said flexible membrane;

a removable mixing container; and

a coupling mechanism that can make an air tight connection between said reservoir and said dispensing mechanism.
