Abstract
The package comprises a commercially available outer standard aerosol container equipped with a standard dispensing valve and a likewise commercially available inner standard aerosol container equipped with a standard dispensing valve. The inner container is arranged substantially coaxially with respect to the outer container, and such inner container is at a greater pressure than the outer container. Both of the dispensing valves of both containers are kinematically coupled in a manner such that upon normal actuation of the outer dispensing valve there is opened the inner dispensing valve. There are provided, for instance, latching cams or the like which retain the inner dispensing valve in its open position. After actuating the outer valve and thus also the inner valve the contents of the inner container empty into the outer container and admix with its contents. The mixture then can be removed in conventional fashion by means of the outer dispensing valve. Apart from the functional reliability and simplicity in handling of the two-compartment package such also exhibits an extremely simple construction, which particularly is realized by virtue of the fact that the package can be fabricated by extensively using standard components.
