ABSTRACT:
A double-chamber aerosol container is constructed using two conventional aerosol receptacles each having a valve at one end. A first of the receptacles is an outer receptacle which contains one of the components of the product to be dispensed. The other of the receptacles is smaller and is contained within the outer receptacle with its valve facing the bottom of the outer receptacle. The inner receptacle contains a propellent gas and a second component of the product to be dispensed. The outer container has an inwardly displaceable closing plug in its bottom which, when displaced inwardly opens the valve in the inner receptacle to discharge the contents of the inner receptacle into the outer receptacle. A sealing gasket surrounding the closing plug permits it to be displaced inwardly while maintaining the sealed condition of the container.
