  • Patent number: 4122978
    Abstract: A pressurized dispensing package includes a container in which the product to be dispensed and a gaseous propellant are stored. The product is dispensed through a discharge passage that extends from a control valve to a terminal orifice. A plural passage flow control member is disposed in the discharge passage. Each passage of the flow control member has a flow dimension in the range of one to one hundred microns and the length of the flow control member several times the passage flow dimension so that a significant pressure drop occurs across the flow control member as the product flows through the member. The total flow area of the flow control passages disposed in the discharge passage is greater than the area of the terminal orifice but less than fifty percent of the area of the discharge passage in which the flow control member is located.
