     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to dispensing of an aerosol product and more particularly to an improved mounting cup for dispensing the aerosol product from a collapsible container within an aerosol container. 
     2. Description of the Related Art 
     An aerosol dispenser comprises an aerosol product and an aerosol propellant contained within an aerosol container. An aerosol valve is provided to control the discharge of the aerosol product from the aerosol container through the fluid pressure provided by the aerosol propellant. 
     The aerosol valve is biased into a closed position. A valve stem cooperates with the aerosol valve for opening the aerosol valve. An actuator engages with the valve stem to open the aerosol valve for dispensing an aerosol product and the aerosol propellant from the aerosol container. The aerosol product and the aerosol propellant are dispensed from the aerosol valve through a spray nozzle. Typically, the aerosol product and the aerosol propellant are contained in a common portion of the aerosol container. 
     Some in the prior art have incorporated an inner container for receiving the aerosol product to separate the aerosol product from the aerosol propellant. In general, the inner container was a flexible container secured to the aerosol valve. The inner container was located within the aerosol container with the aerosol propellant disposed externally inner container. The aerosol propellant applied pressure to the exterior of the inner container to dispense only the aerosol product from the aerosol valve through the spray nozzle. 
     The following U.S. patents represent certain attempts of the prior art to provide an inner container for receiving an aerosol product and for separating the aerosol product from an aerosol propellant. 
     U.S. Pat. No. 3,992,003 to Visceglia et al. discloses an aerosol container having sealed propellant means comprising a flexible propellant bag having air or inert gases under pressure and a predetermined quantity of product located within the container. In a first embodiment, the propellant bag is fixedly mounted at the outlet and includes a separate valve for loading of the pressurized gas. A second valve is mounted at the outlet and is connected to a perforated tube which extends downwardly into the container to emit product when the valve stem is depressed. Actuation of the valve stem causes the propellant bag to expand forcing the product out through the valve. In a second embodiment, the container includes a plurality of product bags which are mounted to a valve arrangement at the outlet and a pressurized propellant which is forced into the container to maintain the product bags under pressure. The valve arrangement comprises a separate valve for each product bag and a valve for loading the propellant into the container tube. The product valves are connected to a mixing cap to emit a predetermined spray when the cap is depressed. In both embodiments of the invention, the propellant is not emitted with the spray and in instances where fluorocarbons are used this is an important ecological advantage. 
     U.S. Pat. No. 4,484,351 to de Leeuwe et al. discloses a storage container formed by joining together the sides and top of a pair of matched laminated flat sheets. The bottom portions are joined together adjacent the sides. The center is sealed along the sealing surfaces of a tube connector assembly. The connector portion is in the form of a parallel pipe head the center of which is enclosed a tube. The tube extends through the connector and projects outwardly therefrom to provide a closable access path for filling and draining the container. The projected portion of said tube is corrugated. A sleeve is formed along the top edge of the sealed top portion of sealed container and a stiffener rod is installed in the sleeve to provide a more stable structure for handling when the container is filled. Below the sleeve and horizontally centered is a hook mounting aperture for holding the container in the drain position. Disposed symmetrically on opposite sides of said hook mounting aperture are a pair of gripping apertures which facilitate handling of the container. At the bottom are a pair of sealed flaps disposed on each side of said tube projection and within each flap is an aperture. These apertures are used to hold a container during the filling cycle. A shut-off cap is a tubular structure and has a wide section, the interior of which fits over the tube projection and a narrow section. The interior walls of said wide section are corrugated so that a fluid tight fit is obtained when installed on said tube projection. A membrane seals the shut-off cap and is formed at the junction of the wide and narrow sections of said shut-off cap. A dust cover is attached by a flexible lead and is designed to fit over a part of the narrow section, thus preventing dust and other contaminants from getting into the narrow tube during storage and transport. 
     U.S. Pat. No. 4,732,299 to Hoyt discloses a collapsible container which has a first pliable member and a second non-pliable member. The first pliable member includes a first pliable sheet and a second pliable sheet which are joined together to form a pouch to hold the contents.

     DETAILED DISCUSSION 
       FIG. 1  is a side view partially in section of an improved aerosol dispenser  10  for dispensing an aerosol product  11  with an aerosol propellant  12 . The improved aerosol dispenser  10  defines an axis of symmetry  13 . An aerosol valve  20  controls the flow of the aerosol product  11  through a valve stem  30  into a valve actuator  40  for discharge from a terminal orifice  42 . The aerosol product  11  and the aerosol propellant  12  are stored within an aerosol container  50 . The aerosol propellant  12  may be any of the propellants used for aerosol dispensers including liquefied propellants such as hydrocarbons and hydrofluorocarbons and any of the compressed gases such as carbon dioxide or nitrogen. 
     The aerosol container  50  is shown as a cylindrical container of conventional design and material. The aerosol container  50  extends between a top portion  51  and a bottom portion  52 . The aerosol container  50  defines a cylindrical sidewall  53  defining a container rim  54  extending about an outer diameter of the aerosol container  50 . The top portion  51  of the aerosol container  50  tapers radially inwardly into a neck  55  terminating in a bead  56 . The bead  56  defines an opening  57  in the aerosol container  50  for receiving a mounting cup  60 . As will be described in greater detail hereinafter, plural gaskets  70  provide a seal for sealing the mounting cup  60  to the aerosol container  50  and for providing a seal for sealing the aerosol valve  20  the mounting cup  60 . 
     A collapsible container  80  is located within the aerosol container  50 . The collapsible container  80  is secured to the mounting cup  60  by a container connector  90 . The collapsible container  80  is selected to contain the aerosol product  11 . 
       FIG. 2  is a side sectional view of the aerosol dispenser of  FIG. 1 . The bottom portion  52  of the aerosol container  50  is closed by an endwall  58  having a filling aperture  59  closed by a plug  59 A. The filling aperture  59  is separate and distinct from the opening  57  in the aerosol container  50  for the mounting cup  60 . The filling aperture  59  enables the aerosol propellant  12  to be introduced into the aerosol container  50  and to be sealed by the plug  59 A after filling with the aerosol propellant  12 . In the alternative, the plug  59 A may be a one-way filling valve for filling the aerosol container  50  with the aerosol propellant  12 . The one-way filling valve  59 A may be a one-way filling valve commonly referred to as an umbrella valve. Preferably, aerosol container  50  is filled by conventional filling machine well known in the art. 
     In the alternative, the aerosol container  50  may be filled with the aerosol propellant  12  through an under the cup filling process. In the under the cup filling process, the aerosol propellant  12  is injected into the aerosol container  50  between the bead  56  of the aerosol container  50  and the mounting cup  60  prior to complete insertion of the mounting cup  60  into the opening  57  of the aerosol container  50 . The under the cup filling process eliminates the need for the filling aperture  59  and the plug  59 A in the aerosol container  50 .

The collapsible container  80  is in an unfilled and collapsed condition for enabling the collapsible container  80  to be inserted through the container opening  57  into the aerosol container  50 . The collapsible container  80  may be rolled about a sleeve (not shown) for enabling insertion into the aerosol container  50 . 
     The peripheral rim  64  of the mounting cup  60  is crimped to the bead  56  of the aerosol container  50  in a conventional fashion. The rim gasket  71  provides a fluid tight seal between the peripheral rim  64  of the mounting cup  60  and the bead  56  of the aerosol container  50 . 
     The aerosol product  11  is introduced into the collapsible container  80 . In one example, the aerosol product  11  is introduced into the collapsible container  80  through the stem passageway  34  of the valve stem  30 . The movement of the valve stem  30  displaces the valve elements  28  from the valve gasket  72  to enable the flow of the aerosol product  11  into the collapsible container  80 . The collapsible container  80  expands within the aerosol container  50  as the aerosol product  11  fills the collapsible container  80 . 
     In another example, the valve stem  30  is depressed and the aerosol product  11  is introduced into the collapsible container  80  around the outer surface  33  of the valve stem  30  and through the aperture  66  in the turret  65 . The pressure of the aerosol product  11  displaces and/or compresses the valve gasket  72  to enable the flow of the aerosol product  11  through the castellation  23 D located about the outer periphery of the valve body  22 D into the collapsible container  80 . The collapsible container  80  expands within the aerosol container  50  as the aerosol product  11  fills the collapsible container  80 . 
     In still another example, the aerosol product  11  is introduced into the collapsible container  80  around the valve body  22  of the aerosol valve  20 . The aerosol product  11  flows through an orifice (not shown) within the mounting cup  60  over the valve gasket  72  and around the outer periphery of the valve body  22 . The pressure of the aerosol product  11  displaces the valve elements  28  from the valve gasket  72  to enable the flow of the aerosol product  11  into the collapsible container  80 . The collapsible container  80  expands within the aerosol container  50  as the aerosol product  11  fills the collapsible container  80 . 
     The propellant  12  is introduced into the aerosol container  50  through the filling aperture  59  located in the endwall  58  of the aerosol container  50 . After the propellant  12  is introduced into the aerosol container  50  through the filling aperture  59 , the filling aperture  59  is sealed by the plug  59 A. The propellant  12  provides external pressure to the collapsible container  80  for discharging the aerosol product  11  through the terminal orifice  42 . In the alternative, the aerosol container  50  may be filled with the aerosol propellant  12  through an under the cup filling process as previously described. 
     One important benefit of the improved mounting cup  10  of the present invention is the ability to fill the aerosol product  11  into the collapsible container  80  around the valve body  22  of the aerosol valve  20 . This method of filling an aerosol container with an aerosol product  11  is commonly referred to as a high speed pressure filling process. 
     Another important aspect of the improved mounting cup  10  of the present invention is the incorporation of the flexible collapsible container  80  containing the aerosol product  11  with the aerosol propellant  12  being contained within the aerosol container  50 . The present invention enables the aerosol valve  20  to be completely isolated from the aerosol propellant  12 . Accordingly, any aerosol valve  20  may be used with any propellant  12  in the present invention. Furthermore, the attachment of the collapsible container  80  to the improved mounting cup  60  inhibits the permeation of the propellant  12  through the valve body  22  of the aerosol valve  20 . 
     The aerosol dispensing device  10  of the present invention enables the aerosol product  11  to be dispensed in any of a three hundred and sixty degree orientation. The three hundred and sixty degree dispensing capability is the result of the uniform pressure applied to the collapsible containers  80  by the aerosol propellant  12 . The aerosol dispensing device  10  is suitable also for dispensing products in a downward direction through the use of an appropriate actuator  40 . Although the invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention.
