1. A foam dispenser comprising:
- a spout mounted at a dispensing location carrying a foam generator,an air inlet tube with an outlet and an inlet,air pump remote from the nozzle operative to dispense air from the air pump into an inlet to the air inlet tube through the tube to the outlet and into the foam generator,a liquid inlet tube with an outlet and an inlet,a liquid reservoir remote from the spout,a liquid pump operative to dispense fluid from the reservoir into the inlet to the liquid inlet tube through the tube to the outlet and into the foam generator,an actuating mechanism activable to operate both the air pump and liquid pump and simultaneously pass air and liquid through the foam generator to dispense foam from the spout,the foam generator having an inlet for the air and an inlet for the liquid and provides for mixing of the air and the liquid to produce a foam,the actuating mechanism comprises a touchless sensor which operates both the liquid pump and the air pump on sensing the presence of a user'"'"'s hand proximate the spout.

12. A foam dispensing apparatus comprising a plurality of foam dispensers, a single liquid reservoir, and a liquid distributor manifold,
each foam dispenser comprising: -
a spout mounted at a dispensing location carrying a foam generator; an air pump mechanism to deliver air to the foam generator; a liquid pump mechanism to deliver liquid from the reservoir to the foam generator; an actuating mechanism actuable to operate both the air pump and liquid pump and simultaneously pass air and liquid through the foam generator to dispense foam from the spout, the liquid distributor manifold placing each liquid pump in communication with the liquid reservoir, said each liquid pump being proximate the liquid reservoir and said each air pump is proximate the spout, a plurality of sinks mounted in a countertop, with each of the foam dispensers associated with a different one of the sinks, the reservoir, liquid distributor manifold and the liquid pumps mounted under the countertop proximate each other with a liquid inlet tube for each said liquid pump communicating the liquid from the liquid pump to the foam generator of its respective spout, the air pump for each foam dispenser mounted under the countertop proximate its respective spout with an air inlet tube for each said air pump providing air from the air pump to the foam generator of its respective spout. - View Dependent Claims (13, 14)
