Pressurized container for two-phase system

摘要

An improved pressure package of the type having a generally rigid container, a liner within the container forming a reservoir containing a product to be dispensed under the influence of a propellant outside the reservoir and valve means closing the container wherein the improvement is the product has a first non-gaseous fluid phase and a second non-gaseous fluid phase, the phases being immiscible and having different densities to form a phase boundary within the reservoir, an orifice for communicating the first phase to the valve and a dip tube for communicating the second phase to the valve.
