Abstract (en)
A cleaning system utilizing a hollow bodied, disposable dispensing package comprising a storage chamber and integral dispensing chamber. The package is connected to the system handle via a conical protrusion on the package closure. An orifice separating the two chambers is provided with a movable, inlet clapper valve, the dispensing chamber outlet orifice being normally closed by a spring urged valve. Deformation of the elastic walls of the bellows shaped dispensing chamber penses a discrete amount of liquid to the system handle with out relying on gravity. Compression of the dispensing chamber reduces the volume thereof, closes the inlet clapper valve, and opens the outlet valve to dispense the product. The conically shaped storage chamber provides for ready pumping and evacuation of cleaning fluid therefrom, the flexible walls collapsing inward as a result of the vacuum created by the decompression of the dispensing chamber. A stiffened side wall in the form of a label or longitudinal ribs further controls the collapse of the storage chamber.
