Abstract
A multi-compartment spray dispenser with common pressurizer includes a single container divided into four sub-chambers, each of which is separate from each of the other sub-chambers. Each sub-chamber has its own separate outlet. A pumping mechanism is common to the sub-chambers and causes pressurization of the sub-chambers simultaneously. When it is desired to dispense liquid from one of the sub-chambers, a hose connection is coupled to the hose connection on the container, thereby opening a flow path for liquid through a hose connected to the hose connector and a nozzle having an actuating valve. Should flow of liquid slow, it is easy to re-pressurize the sub-chamber through operation of the pumping mechanism.
