SELECTIVELY ACTUATED FLUID DISPENSER

摘要

An apparatus includes a selectively actuated fluid system having a plurality of selected fluid reservoirs, for example replaceable cartridge-type fluid reservoirs. A first subset of the reservoirs can be selectively actuated to dispense an individual fluid from the selected reservoir. A second subset of the reservoirs can be simultaneously actuated to dispense two or more fluids in mixed form.

1. An apparatus for dispensing a flowable liquid, mixed from contents of two or more cartridges, comprising:
a first cartridge with a first flowable liquid and a first dispenser pump with an outlet; a second cartridge with a first flowable liquid and a second dispenser pump with an outlet; a manifold with a fluid connection to the outlet of each of the first and second dispenser pumps, a mechanical connection for actuating each of the first and second dispenser pumps and a mixing flow path that receives fluid from the outlet of each of the first and second dispenser pumps and mixes the fluids as the fluids travel to a manifold outlet; a mix manifold cam operably engageable with the manifold to cause a pushing motion for dispenser pump action; and a mix manifold cam driver operably connected to the mix manifold cam for moving the mix manifold cam from a home state through the pushing motion and a return to the home state, said pushing motion causing metered dispensing from each of the first and second dispenser pumps into the manifold, mixing within the converging channels and dispensing of mixed fluids from the first and second dispenser pumps at a manifold outlet.
