Abstract: Disclosed is a package to dispense a composition, wherein the package comprises: a flexible inner container made of gas-impermeable material and holding the composition wherein the composition comprises a blooming agent in an emulsified liquid form; a sealed rigid outer container which encloses the flexible inner container and which is filled with a driving gas compressing the inner container; and a dispenser attached to the inner container and in a fluid connection with the composition by which the composition is allowed to be dispensed by the pressure of the driving gas; wherein the pressure of the driving gas is higher than the vapor pressure of the emulsified liquid blooming agent in the inner container, throughout the usage of the package until the exhaustion of the composition in the inner container.

Abstract: Described herein is an aerosol hairspray product including a container including a container wall which encloses a reservoir. The reservoir includes from about 40% to about 70% of a hairstyling formulation and from about 30% to about 60% of a dimethyl ether propellant. The hairstyling formulation includes water, one or more hairstyling polymers, and from about 0.05% to about 2% alcohol. A spraying device is attached to the container. The spraying devices includes a valve including a valve housing including a vapor tap including a vapor tap area. A dip tube is connected to the valve. The dip tube includes a dip tube orifice including a dip tube orifice area. The ratio of the vapor tap area to the dip tube orifice area is from about 0.005 to about 0.15.

Abstract: A method of making an outer container for an aerosol dispenser and an aerosol dispenser usable with the outer container. The outer container has an upper container portion and complementary lower container portion. A piston is slideably disposed in the upper container portion. The upper container portion and lower container portion are placed proximate to each other. Propellant is disposed into the lower container portion, then the two portions are joined together at a seal.

Abstract: The invention relates to a dispensing apparatus for containing a pressurized composition. The dispensing apparatus comprises a reservoir for containing the composition, a flow conduit in fluid communication with the reservoir having a distal end forming a flow conduit orifice; and a displaceable actuator head comprising a side wall having an interior surface and a dispensing orifice formed through the side wall. An intermediate member having an aperture extending there through is interposed between the interior surface of the displaceable actuator head and the distal end of the flow conduit. The intermediate member is affixed to either the interior surface of the actuator head aligning the aperture with the dispensing orifice or to the distal end of the flow conduit aligning the aperture with the flow conduit orifice. The intermediate member seals the dispensing orifice when the displaceable actuator head is biased to an at-rest position.
