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 second flowable liquid and a second dispenser pump with an outlet;
a manifold with a flow 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 comprising an upper manifold section with channels converging at an intersection point that receives the first flowable liquid and second flowable liquid from the outlet of each of the first and second dispenser pumps and mixes these liquids as they travel from the intersection point along a downstream flow manifold to a manifold outlet, said downstream flow manifold including at least one bend of approximately 180°
followed by at least one static mixer;
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 first flowable liquid and second flowable liquid from the first and second dispenser pumps at a manifold outlet.

Abstract
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.

10. A method for dispensing a flowable liquid, mixed from contents of two or more cartridges, comprising:
-
providing a first cartridge with a first flowable liquid and a first dispenser pump with an outlet; providing a second cartridge with a second flowable liquid and a second dispenser pump with an outlet; providing a mix manifold with a flow 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 flowable liquid from the outlet of each of the first and second dispenser pumps and by converging channels causes mixing, as dispensed first and second flowable liquids travel in an upper manifold section with channels converging at an intersection point and from the intersection point along a downstream flow manifold to a manifold outlet; providing a mix manifold cam operably engageable with the manifold to cause a pushing motion; actuating a mix manifold cam driver operably connected to the mix manifold cam for moving the manifold pusher 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 first and second flowable liquids from the first and second dispenser pumps at the manifold outlet; and dispensing a selectable further flowable liquid, comprising; providing a third cartridge with a third flowable liquid and a third dispenser pump with an outlet and a fourth cartridge with a fourth flowable liquid and a fourth dispenser pump with an outlet, and controlling a time-of-day driver selectively operably connected to either a third dispenser pump cam or a fourth dispenser pump cam for moving a selected one of the third dispenser pump or the fourth dispenser pump from a home state through a pushing motion and a return to its home state, said pushing motion causing metered dispensing from the selected one of the third dispenser pump or fourth dispenser pump at its outlet. - View Dependent Claims (11, 12, 14, 15)
