Countermount foam dispenser

A countermount foam dispenser comprising:

• a. a spout including a spout nozzle with a spout opening;
• b. a spout mounting shaft mounted to the spout at a mounting shaft bracket;
• c. a mixer pump housing having a spout retainer latch, wherein the mixer pump housing houses a mixer pump, wherein the mixer pump includes a motor, wherein the motor includes a motor shaft, wherein the motor shaft has a crank, wherein the crank actuates a piston handle, wherein the piston handle depresses a piston diaphragm at piston diagram tips, wherein the piston diaphragm tips are configured to change the volume of the piston diaphragm when the piston handle depresses the piston diaphragm, wherein the piston diaphragm is configured to change the pressure against an output cover, wherein the piston diaphragm aspirates air from an air inlet port, and then blows the air to mix the air with liquid soap at a mixer;
• d. a partition pump manifold including an air partition and a liquid partition, wherein the liquid partition segments a liquid conduit proximal portion from a liquid conduit distal portion, wherein the air partition segments and air conduit proximal portion from an air conduit distal portion;
• e. a bottle for containing liquid soap, wherein the bottle has a connection to the mixer pump housing at the liquid inlet port;
• and
• f. batteries located on the mixer pump housing, wherein the batteries power the mixer pump for extracting liquid soap from the bottle, wherein the batteries also power a circuit board mounted in the mixer pump housing, and wherein the batteries also power a sensor, wherein the sensor is mounted to the spout extension front housing.

A bottle for a countermount foam dispenser comprising:

• a. a bottle sidewall extending vertically;
• b. a shoulder extending from the bottle sidewall at an upper portion of the bottle;
• c. a bottle neck extending upwardly from the shoulder, wherein the bottle neck includes a neck groove interrupted by a rotation stop, wherein the rotation stop is formed as a protrusion that protrudes horizontally away from the neck;
• d. an adapter mounted to the bottle neck, wherein the adapter has an adapter sidewall, wherein the bottle neck includes adapter protrusions extending away from the bottle neck, wherein the adapter includes adapter hooks configured to permanently snap to the neck groove and form a seal between the neck and the adapter;
• and
• e. an adapter gasket having an adapter port opening for forming a seal, wherein the adapter gasket is mounted to an adapter port of the adapter.
