Abstract: A novel and useful mixture cartridge apparatus for a shaving lather dispenser apparatus incorporates a mixture cartridge having a body with first and second openings, a cavity in communication with the first and second openings, and a first fluid control valve. The cavity is configured to contain a liquid shaving lather solution. The first fluid control valve is configured to control a flow of the fluid through the second opening. The first fluid control valve is configured to be opened to provide flow of the liquid shaving lather solution through the second opening when coupled to an actuator of a lather dispenser. The first opening is configured to equalize pressure within the cavity with atmospheric pressure.

Abstract: A novel and useful pump fed shaving lather generator apparatus incorporating a body having a cavity and an inlet port, A removable mixture cartridge includes a reservoir for containing a fluid, an outlet port extension coupled to the reservoir and configured to be releasably coupled to the inlet port. A first valve selectively controls flow of the fluid from the outlet port extension. A lather generator is situated within the cavity of the body and defines a cylindrical cavity with first and second openings. A cylindrical lather generating screw (LGS) situated within the cylindrical cavity is configured to generate a lather from the fluid. A motor coupled to the LGS and configured to rotate the LGS within the cylindrical cavity of the lather generator to drive the LGS to output the generated lather at the second opening.
