Description: INVERTED AEROSOL DISPENSER BACKGROUND OF THE INVENTION Field of The Invention This invention relates to aerosol dispensing devices and more particularly to an improved aerosol dispensing device for discharging an aerosol product in a generally downwardly direction. Description of the Prior Art An aerosol dispensing device comprises an aerosol valve located internal an aerosol container. 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 from the aerosol container. The aerosol product is dispensed from the aerosol valve through a spray nozzle. Various types of actuators have been utilized by the prior art for actuating an aerosol dispensing device. The first and the most basic type of actuator for an aerosol dispensing device is an actuator button that is affixed to the valve stem. A depression of the actuator button depresses the valve stem to open the aerosol valve for dispensing the aerosol product from the aerosol container. A protective cap is utilized for engaging with a rim of the aerosol container for inhibiting accidental actuating of the aerosol button. The second type of actuator for an aerosol dispensing device is an aerosol overcap. The aerosol overcap replaces the conventional protective cap and includes an actuator for actuating the aerosol valve of the aerosol dispensmg device. The aerosol overcap comprises a base engagable with the rim of the aerosol container for mounting the overcap to the aerosol container. The aerosol over cap includes an actuator pivotably mounted to the overcap base and engaging with the valve stem. The movement of the actuator of the aerosol overcap causes a depression of the valve stem to open the aerosol valve for dispensing the aerosol product from the aerosol container. A third type of actuator for actuating an aerosol dispensing device is a trigger device. In this third type of actuators, a base is mounted either to the container rim or the mounting cup rim for supporting a trigger. The trigger is engagable with the valve stem. A movement of the trigger from an extended position to a protracted position depresses the valve stem to open the aerosol valve for dispensing the aerosol product from the aerosol container. The following United States Patents represent some of the trigger devices for dispensing the aerosol product from the aerosol container. Aerosol dispenser devices traditionally dispense lower viscosity aerosol products such as hair spray, paint, deodorant, and the like in a spray form. The spray nozzle and aerosol valve is traditionally located on the top of the aerosol container for dispensing the aerosol products through the spray nozzle in an upright position. Typically, high viscosity aerosol products like shaving gels as well as foaming aerosol products such as shave crea are stored in an upright position and are dispensed in an upright to horizontal position. Other high viscosity foaming aerosol products such as hair mousse and rug cleaner are stored in an upright position but are dispensed in an inverted position. The high viscosity foaming aerosol products that are dispensed in an inverted position are not designed to dispense in an upright position. If these foaming aerosol products are actuated in a upright oriented position, only the aerosol propellant would escape from the aerosol container and the aerosol product would remain in the aerosol container. This loss of the aerosol propellant may deplete the aerosol propellant prior to the complete dispensing of the aerosol product from the aerosol container.

U.S. Patent 3,979,163 discloses a cleaning and scrubbing tool having a cleaning head and aerosol can handle in which a suitably operational scrub pad is supported by head bracket extension in free cleaning liquid passing relation, interlocked with portions of the pad by localized deflection of the extension, suitably by locally heating or solvating the extension to deflectable condition within the pad interior. U.S. Patent 4,416,398 discloses a plural spray rate aerosol assembly for use with an aerosol container having a plural spray rate valve. The assembly comprises an actuator button having a terminal orifice connected through a valve stem to the plural spray rate valve for enabling a first discharge rate of the aerosol product from the terminal orifice upon opening the valve in a first position and for enabling a second discharge rate of the aerosol product from the terminal orifice upon opening the valve in a second position. An overcap is rotatably secured to the aerosol container and includes a finger actuator movably mounted relative to the overcap. A non- symmetrical aperture is disposed in either the actuator button or the finger actuator for cooperation with a non-symmetrical element in the other of the actuator button and the finger actuator. The non-symmetrical element is inhibited from entering the non- symmetrical aperture for transferring the finger movement of the operator to open the valve in the first position upon a first selected orientation of the finger actuator relative to the actuator button. The non-symmetrical element enters the non- symmetrical aperture for transferring the finger movement of the operator to open the valve in the second position upon a second selected orientation of the finger actuator relative to the actuator button. U.S. Patent 5,385,272 to Aoun discloses a hand held, free standing, bottom dispensing dispenser, generally made of plastic, for the dispensing of thick liquids such as lotions, shampoos, and processed foodstuff, having a resiliently walled reservoir that sits atop a stand that offers fulcrum for a mechanical linkage. The linkage has a top portion engaged to the reservoir side wall allowing the user's hand to grasp and manipulate the linkage while grasping and manipulating the reservoir. A bottom portion is coupled to dispensing valve disposed and adapted to open and close a discharge element affixed to an outlet in the bottom end of the reservoir. Thus, when hand pressure is applied to the linkage top portion at the same time the reservoir is squeezed and the motion transmitted by the linkage to the dispensing valve opens the latter to dispense a portion of the content. When pressure is relieved, the resilient reservoir side wall rebounds back to its initial shape and, the reservoir side wall being engaged to the linkage moves the latter back to its initial position. Thus while causing the dispensing valve to gradually close, the reservoir side wall outward movement induces in the reservoir an air flow that draws the fluid in the discharge element in therewith. The dispenser content is always located in the lower part of the reservoir near its aperture, ready to be dispensed therefore making possible the dispensing of virtually all the content.

DETAILED DISCUSSION FIGS. 1 and 2 are top and bottom isometric views of a first embodiment of an aerosol dispensing device 10A for dispensing an aerosol product 14 incorporating the present invention. The aerosol dispensing device 10A dispenses the aerosol product 14 through an aerosol propellant 16 from an aerosol container 20A. The aerosol dispensing device 10A of the present invention enables the aerosol container 20A to be stored in an inverted position. The aerosol dispensing device 10A dispenses the aerosol product 14 under the pressure of the aerosol propellant 16 in a generally downward direction through the undercap 30A. The invention is particularly useful in dispensing viscous aerosol products 14. FIGS. 3 and 4 are sectional views of FIG. 1 illustrating an undercap 30A secured to the aerosol container 20A by a mounting 40A for supporting the aerosol container 20A. The undercap 30A includes an actuator 50A pivotably connected to the undercap 30A by a binge 60A. The actuator 50A is positioned for actuating a valve button 70A connected to an aerosol valve 80A mounted to the aerosol container 20A. The actuation of the aerosol valve 80A enables the aerosol product 14 to be dispensed under the pressure of the aerosol propellant 16 from the aerosol container 20A and to be discharged from the valve button 70A. FIGS. 3 and 4 illustrate the actuator 50A in an unattended condition. The container 20A is shown as a cylindrical container of conventional design disposed in an inverted orientation. The aerosol container 20A extends between a top portion 21A and a bottom portion 22A. The top portion 21 A of the aerosol container 20A is closed by an endwall. The aerosol container 20A defines a cylindrical sidewall 23A defining a container rim 24A extending about an outer diameter of the aerosol container 20A. The bottom portion 22A of the aerosol container 20A tapers radially inwardly into a neck 25A terminating in a bead 26A. A flange 28A extends radially outward about the neck 25A of the aerosol container 20A. The aerosol container 20A defines an axis of symmetry 29A. The bead 26A supports an aerosol mounting cup 90A for sealably securing the aerosol valve 80A to the aerosol container 20A. The aerosol container 20A may be made of a metallic material or a non-metallic material, hi this example, the aerosol container 20A is shown as a plastic bottle. The aerosol product 14 is contained near the bottom portion 22A of the aerosol container 20A whereas the aerosol propellant 16 is contained near the top portion 21 A of the aerosol container 20 A. The aerosol dispensing device 10A is especially suited for dispensing viscous products like shampoo, hair conditioner, hair gel, hair mousse or non-foaming soap, hi addition, the aerosol dispensing device 10A is especially suited for dispensing viscous food products such as ketchup, mustard, mayonnaise and the like. The aerosol dispensing device 10A is suitable also for dispensing products such as fttrniture polish in a downward direction through the use of a appropriate valve button 70 A. The aerosol propellant 16 may be compressed gas, carbon dioxide or any other suitable propellant. FIGS. 5-7 and 8-10 are enlarged views of portions of FIGS. 3 and 4 respectively. The undercap 30A has a top portion 31 A and a bottom portion 32A with a sidewall 33 A extending therebetween. The undercap 30A includes an enlarged base 34A for providing a greater stability to the aerosol dispensmg device 10A. The enlarged base 34A compensates for the higher center of gravity of the aerosol dispensing device 10A than found in conventional aerosol dispensers. Preferably, the undercap 30A is formed from a unitary and resilient polymeric material such as polypropylene, polyethylene, polyolyfin or any other suitable polymeric material. The undercap 30A mcludes a gripping area 36A having an elliptically-shaped cross-section. The elliptically-shaped cross-section provides a superior ergonomic shape. Preferably, the undercap 30A comprises a plastic shell defining an undercap aperture 38A. The undercap aperture 38A provides a passage for dispensing the aerosol product 14 in a generally downward direction through the undercap 30A. A sidewall orifice 39A is defined in the sidewall 33A of the undercap 30A. The undercap 30A is secured to the aerosol container 20 A by a mounting shown generally as 40 A. In the example, the mounting 40A comprises a plurality of ribs 41A- 44 A extending inwardly from the sidewall 33 A of the undercap 30 A. The plurality of ribs 41A-44A having recesses 45A-48A for securing the undercap 30A to the aerosol container 20A in a snap locking engagement. In this example of the invention, the plurality of ribs 41A-44A secures the undercap 30A to the flange 28 A extending radially outward from the neck 25 A of the aerosol container 20A. The recesses 45A-48A of the plurality of ribs 41 A-44A received the flange 28 A to secure the undercap 30A to the aerosol container 20A in a snap locking engagement. The top portion 31 A of the undercap 30A is received within the container rim 24 A of the aerosol container 20A. The actuator 50A is located in the sidewall orifice 39A of the sidewall 33A of the undercap 30A for actuating the aerosol valve 80A. In this first embodiment of the aerosol dispensing device 10A, the actuator 50A is shown as plural actuators 50A and 50A' located on opposed sides of the elliptically-shaped cross-section of the gripping area 36A. The plural actuators 50A and 50A' are substantially identical to one another. Each of the plural actuators 50A and 50A pivots about hinges 60A and 60A' having hinge axes 61 A and 61A. The hinge axes 61A and 61A' are substantially parallel to the axis of symmetry 29A extend through the aerosol container 20A. Each of the plural actuators 50A and 50 A' and the hinges 60A and 60A' are integrally connected to the undercap 30A. The plural actuators 50A and 50A pivot on hinges 60A and 60A to extend into the sidewall orifice 39A. The aerosol valve 80A is located at the bottom portion 22A of the aerosol container 20A. The aerosol valve 80A is secured into the aerosol mounting cup 90A in a conventional fashion. The aerosol mounting cup 90A is crimped to the bead 26A of the container 20A for sealably securing the aerosol valve 80A to the aerosol container 20A. The aerosol valve 80A is disposed within the aerosol container 20A with the valve stem 82A extending downward from the aerosol container 20A. The valve button 70A is secured to the valve stem 82A. The valve button 70A extends between a top portion 71 A and a bottom portion 72A. The top portion 71 A of the valve button 70A is provided with a socket 73 A for frictionally receiving the valve stem 82A of the aerosol valve 80A. The bottom portion 72A of the valve button 70A is defined by an enlarged side surface 74A. A channel 76A extends through the valve button 70A to provide fluid communication between the valve stem 82A of the aerosol valve 80A and a terminal orifice 78A of the valve button 70A. FIGS. 11 and 12 are sectional views similar to FIGS. 3 and 4 illustrating the actuator 50A in an actuated condition. The valve stem 82A of the aerosol valve 80A displaces the aerosol valve 80A between a biased closed position as shown in FIGS. 3 and 4 to an open position as shown in FIGS. 11 and 12. When the valve stem 82 A is displaced into the open position as shown in FIGS. 11 and 12, the aerosol dispensing device 10A dispenses the aerosol product 14 under the pressure of the aerosol propellant 16 in a generally downward direction through the undercap 30A from the valve button 70A. FIGS. 13-15 and 15-18 are enlarged views of portions of FIGS. 11 and 12 respectively. The aerosol valve 80A is shown as a tilt valve wherein the tilting the valve button 70A tilts the valve stem 82A of the aerosol valve 80A. The tilting of the valve stem 82A displaces the aerosol valve 80A from the biased closed position to the open position. However, it should be understood that the invention may be modified to function with a vertical action valve wherein a vertical movement of the valve stem 82 A displaces the aerosol valve 80A from the biased closed position to the open position. The actuators 50A and 50A' are movably mounted relative to the undercap 30A for moving the valve button 70A and the valve stem 82A upon displacement of one or both of the actuators 50A and 50A. The displacement of the actuators 50A and 50A' move the aerosol valve 80A into the open position to dispense the aerosol product 14 under the pressure of the aerosol propellant 16 in a generally downward direction through the undercap 30A. The actuators 50A and 50A include actuator surfaces 52A and 52A' extending radially inwardly from the actuators 50A and 50A'. The actuator surfaces 52A and 52A' engage the valve button 70A upon an inward movement of the actuators 50A and 50A'.
