Formulation delivery systems, devices, and methods

A formulation delivery system, comprising:

• a reusable handle configured to receive a cartridge, the cartridge forming part of a formulation product line including a plurality of different cartridge types, each cartridge type selected from a cleaning cartridge type or a formulation cartridge type;
• a formulation dispensing assembly including a reciprocating nozzle assembly fluidically couple-able to the cartridge received within the reusable handle;
• and
• a controller including computational circuitry and logic configured to:
• authenticate the cartridge after insertion into the reusable handle;
• and
• execute, based upon authenticating the cartridge:
• a cleaning routine that dispenses a cleaning liquid from the cartridge through the formulation dispensing assembly, or
• a haircare formulation routine that dispenses a haircare formulation from the cartridge through the formulation dispensing assembly, wherein the controller is further configured to pump a cleaning liquid at a higher flow rate in the cleaning routine as compared to flow rate in the haircare formulation routine.

A formulation cartridge, comprising:

• a reusable cartridge body;
• a valve frame including at least one valve engagement unit;
• and
• a disposable refill packet reversibly coupleable to the reusable cartridge body, the disposable refill packet including:
• a formulation packet having at least one valve, and
• a body portion configured for insertion into the reusable cartridge body,
• wherein the valve frame is configured to receive and secure the at least one valve of a formulation packet, and
• wherein the formulation cartridge is configured for insertion into a cartridge cavity of a formulation delivery device, wherein the formulation cartridge includes a handle portion on one end and a tray portion extends from the handle portion, the tray portion has a U-shape with a flat docking surface for correct insertion of the formulation cartridge in a reusable handle having a cartridge cavity with an opening at one end of the reusable handle, wherein the cartridge cavity includes a flat docking surface which defines the opening as a segment of a circle.
