DETAILED DISCUSSION

(33) FIGS. 1 and 2 illustrate a first embodiment of the improved aerosol spout dispenser 10 of the present invention for dispensing an aerosol product 11 with an aerosol propellant 12. The terms aerosol product 11 and aerosol propellant 12 as used herein includes all types of pressurized package dispenser including pressurized gases or bag on valve dispensers.

(34) The aerosol spout dispenser 10 defines an axis of symmetry 13 of the aerosol spout dispenser 10. An aerosol valve 20 having a valve stem 30 cooperates with the aerosol spout dispenser 10 to control the flow of the aerosol product 11 from an aerosol container 40.

(35) The aerosol container 40 is shown as a cylindrical container of conventional design and material. The aerosol container 40 extends between a top portion 41 and a bottom portion 42 with a cylindrical sidewall 43 located therebetween. The bottom portion 42 of the aerosol container 40 is closed by an endwall 44. Although the aerosol container 40 has been shown as a conventional design, it should be understood that the aerosol spout dispenser 10 of the present invention may be used with aerosol containers of various designs.

(36) As best shown in FIG. 2, the aerosol container 40 terminates in a bead 46 defining an opening 47 in the aerosol container 40 for receiving a mounting cup 50. The mounting cup 50 includes a peripheral rim 52 for sealing to the bead 46 of the aerosol container 40. The mounting cup 50 further comprises a turret 54 for receiving the aerosol valve 20.

(37) The aerosol valve 20 includes a valve body 22 secured to the turret 54 of the mounting cup 50 by a conventional crimping process. The valve body 22 defines an internal valve cavity 24 in fluid communication with the aerosol container 40 through a dip tube 26. The aerosol valve 20 includes a valve element 28 positioned within the internal valve cavity 24. A bias spring 29 biases the valve element 28 into a closed position to inhibit the flow of the aerosol product 11 through the valve stem 30.

(38) The valve stem 30 extends between a first end 31 and a second end 32 and defines an outer surface 33 with a stem passageway 34 extending therein. The stem passageway 34 provides fluid communication from the internal valve cavity 24 of the valve body 22 to the second end 32 of the valve stem 30. A depression of the valve stem 30 moves the valve element 28 into an open position against the urging of the bias spring 29 to permit the flow of the aerosol product 11 from the second end 32 of the valve stem 30.

(39) FIGS. 3-6 are various enlarged views of the aerosol spout dispenser 10 of the present invention. The aerosol spout dispenser 10 comprises a base 60 extending between a top portion 61 and a bottom portion 62 with a cylindrical sidewall 63 located therebetween. The sidewall 63 of the base 60 defines an outer surface 64 and an inner surface 65 coaxial with the axis of symmetry 13 of the aerosol spout dispenser 10.

(40) The base 60 includes a base mounting 66 for securing the base 60 to the aerosol container 40. The base mounting 66 is shown as annular base projections 66 extending radially inwardly for securing the base 60 to the aerosol container 40. In this example, the annular base projection 66 engages with the bead 46 of the aerosol container 40. However, it should be understood that various conventional structures may be used for securing the base 60 to the aerosol container 40.

(41) The base 60 includes a base retainer 67 for rotationally securing a dispensing head 70 to the base 60. The base retainer 67 comprises a plurality of annular projections 67 extending radially outwardly from the base 60. The plurality of annular projections 67 are distributed about the axis of symmetry 13 of the aerosol spout dispenser 10.

(42) The dispensing head 70 is shown as unitary member extending between a top portion 71 and a bottom portion 72 with a cylindrical sidewall 73 located therebetween. The sidewall 73 of the dispensing head 70 is a substantially rigid sidewall 73 defining an outer surface 74 and an inner surface 75 coaxial with the axis of symmetry 13 of the aerosol spout dispenser 10. The substantially rigid sidewall 73 of the dispensing head 70 supports a rigid top surface 76.

(43) The dispensing head 70 includes a dispensing head retainer 77 for cooperating with the base retainer 67 for rotationally securing the dispensing head 70 to the base 60. The dispensing head retainer 77 is shown as a plurality of annular projections 77 extending radially inwardly from the inner surface 75 of the sidewall 73 of the dispensing head 70. The radially inwardly extending dispensing head retainers 77 cooperate with the radially outwardly extending base retainers 67 for rotationally securing the dispensing head 70 to the base 60 for inhibiting separation of the dispensing head from the base when a separating force is applied between the dispensing head and the base.

(44) A dispensing spout 80 is formed as a one-piece unit with the dispensing head 70. The dispensing spout 80 extends between a first end 81 and a second end 82. A nozzle passageway 83 is defined within the dispensing head 70 and the dispensing spout 80. An inner end of the nozzle passageway 83 defines a socket 84 for frictionally receiving the first end 31 of the valve stem 30 of the aerosol valve 20. An outer end of the nozzle passageway 83 defines a terminal orifice 86.

(45) The dispensing spout 80 has a portion thereof extending normal to the axis of symmetry 13 of the base 60 beyond the mounting cup 50 of the aerosol container 40. More specifically, the second end 82 of the dispensing spout 80 extends radially outwardly beyond the peripheral rim 52 of the mounting cup 50. The dispensing spout 80 provides an unobstructed view of the delivery of the aerosol product 11 from the terminal orifice 86.

(46) As will be described in greater detail hereinafter, the dispensing head 70 is tiltable relative to the base 60 for actuating the aerosol valve 20 to dispense the aerosol product 11 from the aerosol container 40 through a dispensing spout 80 of the dispensing head 70. The aerosol spout dispenser 10 includes two independent surfaces for actuating the aerosol valve 20. A first actuating surface 91 is formed on an upper surface of the dispensing spout 80 for receiving a finger of a user. A depression of the first actuating surface 91 of the dispensing spout 80 actuates the aerosol valve 20 for discharging aerosol product from the terminal orifice 86 as will be described in greater detail hereinafter. A second actuating surface 92 is formed on a surface of the dispensing head 70 for receiving a finger of a user.

(47) The dispensing head 70 is rotatable relative to the base 60 between an unlocked rotational position as shown in FIGS. 19-24 to a locked rotational position as shown in FIGS. 25-30. The dispensing head 70 is tiltable relative to the base 60 to dispense the aerosol product 11 from the aerosol container 40 when the dispensing head 70 is rotated into the unlocked rotational position as shown in FIGS. 19-24. The dispensing head 70 is inhibited from tilting relative to the base 60 when the dispensing head 70 is moved into the locked rotational position as shown in FIGS. 25-30.

(48) FIGS. 7-12 are various views further illustrating the base 60 shown in FIGS. 3-6. The first end 61 of the base 60 defines an outer ring 100. The outer ring 100 is a substantially cylindrical upper portion of the cylindrical sidewall 63. A plurality of radial ribs 102 extend inwardly from the inner surface 65 of the cylindrical sidewall 63. The plurality of radial ribs 102 supports an inner ring 110. The outer ring 100 and the inner ring 110 are coaxial with the axis of symmetry 13 of the aerosol spout dispenser 10.

(49) An inner base platform 112 extends radially inwardly from the inner ring 110 and defines a central platform aperture 114 coaxial with the outer ring 100 and the inner ring 110. Preferably, the plurality of radial ribs 102 and the inner ring 110 and the inner base platform 112 are integrally formed with the base 60. As best shown in FIGS. 11 and 12, an array of base platform ribs 116 extend from the inner ring 110 to support the underside of the inner base platform 112. The inner base platform 112 defines the central platform aperture 114.

(50) The inner ring 110 supports the base retainer 67 for cooperating with the dispensing head retainer 77 for rotationally securing the dispensing head 70 to the base 60. The base retainer 67 is shown as a plurality of annular projections 67 extending radially outwardly from the inner ring 110 of the base 60. The plurality of annular projections 67 are distributed about the axis of symmetry 13 of the aerosol spout dispenser 10.

(51) Preferably, the inner ring 110 of the base 60 is deformable for enabling the dispensing head retainer 77 to pass over the base retainer 67. After the dispensing head retainer 77 passes over the base retainer 67, the base retainer 67 engages with the dispensing head retainer 77 to retain the dispensing head 70 on the base 60. The dispensing head retainer 77 of the dispensing head 70 interlocks with the base retainer 67 for rotationally securing the dispensing head 70 to the base 60.

(52) The dispensing head retainer 77 of the dispensing head 70 interlocks with the base retainer 67 for inhibiting separation of the dispensing head from the base when a separating force is applied between the dispensing head and the base. The dispensing head retainers 77 and the base retainers 67 inhibits a user from grasping the aerosol container 40 or the base 60 with one user hand and grasps the dispensing head 70 with a second user hand and attempts to remove the dispensing head 70 from the base 60.

(53) A void 120 is defined between the outer ring 100 and the inner ring 110 of the base 60. A bridge 125 extends across the void 120 between the outer ring 100 and the inner ring 110 of the base 60. Preferably, the bridge 125 extends across a portion of the void 120 and is located at a level below the first end 61 of the base 60. The bridge 125 occupies a minor portion of the circumference of the inner ring 110. In this example, the bridge 125 occupies a five to ten degree arc portion of the circumference of the inner ring 110 about the axis of symmetry 13 of the aerosol spout dispenser 10.

(54) The base 60 includes a base stop 130 for cooperating with the dispensing head 70 for establishing an unlocked rotational position and a locked rotational position of the dispensing head 70 relative to the base 60. More specifically, the base stop 130 extends upwardly from the inner base platform 112 and extends inwardly from the inner ring 110 to selectively interfere with the rotation of the dispensing head 70. The base stop 130 includes a locked position stop 131 and an unlocked position stop 132 defined by circumferentially spaced apart lateral surfaces 131 and 132 of the base stop 130. Preferably, the base stop 130 is integrally formed with the inner ring 110 and the inner base platform 112. The locked position stop 131 establishes a locked rotational position of the dispensing head relative to the base 60 as shown in FIGS. 25-30. The unlocked position stop 132 establishes an unlocked rotational position of the dispensing head relative to the base 60 as shown in FIGS. 19-24.

(55) The base 60 includes audible actuator rib 140 for cooperating with the dispensing head 70 for audibly indicating the rotational position of the dispensing head 70 relative to the base 60. In this example, the audible actuator rib 140 comprises plural audible actuator ribs 141 and 142. Each of the plural audible actuator ribs 141 and 142 extends upwardly from the inner base platform 112 and extends inwardly from the inner ring 110.

(56) The aerosol spout dispenser 10 comprises a lock 145 for locking the tilting of the dispensing head 70 relative to the base 60. The lock 145 includes grooves 150 defined on the base 60 cooperating with groove ribs 180 extending from the dispensing head 70. The groove 150 defined in the base 60 receives the groove ribs 180 extending from the dispensing head 70 for enabling the dispensing head 70 to the tilted relative to the base 60 as shown in FIGS. 19-24.

(57) More specifically, the groove 150 includes a plurality of inner grooves 151-153 formed within the inner ring 110 of the base 60. Each of the plurality of inner grooves 151-153 extends through the inner ring 110 to a level in proximity to the inner base platform 114 of the base 60. A base notch 155 is defined in the outer ring 100 of the base 60. The base notch 155 extends through the outer ring 100 to a level commensurate with the level of the plurality of inner grooves 151-153.

(58) Referring to FIGS. 5, 9 and 10, the aerosol spout dispenser 10 may include a rotation indicator 160 for indicating the rotational position of the dispensing head 70 relative to the base 60. Preferably, the rotation indicator 160 includes a locked rotational position indicator 161 and an unlocked rotational position indicator 162. A rotation marker 164 on the dispensing head 70 functions as an alignment indicator for the locked and unlocked rotational position indicators 161 and 162. In this example, the locked and unlocked rotational position indicators 161 and 162 are located on the outer surface 64 of the base 60, but it should be appreciated by those skilled in the art that numerous variations in the arrangement of the rotation indicator 160 may be incorporated within the present invention.

(59) FIGS. 13-18 are various views further illustrating the dispensing head 70 shown in FIGS. 3-6. The first actuating surface 91 is formed on the top surface 76 of the dispensing head 70. The interior of the dispensing head 70 includes an audible emitting rib 170 shown as an extending projection extending from the rigid top surface 76 of the dispensing head 70. The audible emitting rib 170 interacts with the plural audible actuator ribs 141 and 142 of the base 60. The audible emitting rib 170 sequentially contacts the plural audible actuator ribs 141 and 142 to produce an audible double click upon rotation of the dispensing head 70 relative to the base 60 when the dispensing head is moved between the locked and unlocked rotational position. The dispensing head 70 includes the groove ribs 180 extending from the inner surface 75 and the rigid top surface 76 of the dispensing head 70. Preferably, the groove ribs 180 are formed as a one-piece unit of the actuator button 70. More specifically, the groove ribs 180 includes inner grooves 181-183 equally spaced about the axis of symmetry 13 of the aerosol spout dispenser 10. A dispensing head boss 185 is formed on the outer surface 76 of the dispensing head 70.

(60) The plurality of groove ribs 181-184 of the dispensing head 70 are misaligned with the plurality of grooves 151-153 defined by the inner ring 110 of the base 60 when the dispensing head 70 is located in the locked rotational position as shown in FIGS. 25-30. Similarly, the head boss 185 of the dispensing head 70 is misaligned with the base notch 155 defined by the outer ring 100 of the base 60 when the dispensing head 70 is located in the locked rotational position as shown in FIGS. 25-30.

(61) The plurality of groove ribs 181-183 of the dispensing head 70 are aligned with the plurality of grooves 151-153 defined by the inner ring 110 of the base 60 when the dispensing head 70 is established in the unlocked rotational position as shown in FIGS. 19-24. In the unlocked rotational position, the head boss 185 is aligned with the base notch 155 defined by the outer ring 100 of the base 60.

(62) As will be described hereinafter, the groove ribs 183 and 184 interact with the locked position stop 131 and the unlocked position stop 132 of the base stop 130 for establishing the locked rotational position and the unlocked rotational position of the dispensing head 70 relative to the base 60.

(63) FIGS. 19-22 are various views of the aerosol spout dispenser 10 of FIGS. 1-6 with the dispensing head 70 being located in the unlocked rotational position. The dispensing head 70 is rotated clockwise relative to the base 60 until the groove rib 183 of the dispensing head 70 engages the lock position stop 131 of the base 60. During the clockwise rotation of the dispensing head 70 from the unlocked rotational position to the locked rotational position, the audible emitting rib 170 of the dispensing head 70 passes over the plural audible ribs 141 and 142, respectively, to provide two independent audible clicks. The audible emitting rib 170 of the dispensing head 70 cooperates with the audible rib 142 to maintain the dispensing head 70 in the locked rotational position.

(64) When the dispensing head 70 is located in the unlocked rotational position, the plurality of groove ribs 181-184 are aligned with the plurality of grooves 151-154 of the base to enable the dispensing head 70 to tilt relative to the base 60. The groove rib 184 is aligned with the bridge 125. The alignment of the groove ribs 181-184 with the grooves 151-154 permits the dispensing head 70 to be tilted relative to the base 60 to actuate the aerosol valve 20.

(65) FIG. 21 is a magnified view of a portion of FIG. 20 illustrating an auxiliary latching mechanism 210. The auxiliary latching mechanism 210 inhibits separation of the dispensing head 70 from the base 60. The dispensing spout 80 of the dispensing head 70 provides a mechanical advantage for intentionally or inadvertently separating the dispensing head 70 from the base 60. The dispensing head 70 can be separated from the base 60 by (1) an excess depressing force applied to the dispensing spout 80, (2) an excess lifting force applied to the dispensing spout 80 and (3) an improper use and/or abuse of the aerosol spout dispenser 10. The auxiliary latching mechanism 210 inhibits such intentional or inadvertent separation of the dispensing head 70 from the base 60.

(66) The auxiliary latching mechanism 210 comprises arcuate base locking plate 212 extending from the inner base platform 112 into the central platform aperture 114 of the base 60. The arcuate base locking plate 212 is unitary with the base 60. An arcuate lock slot 214 is defined in the arcuate base locking plate 212. The arcuate base locking plate 212 includes a tapered surface 216 and a locking plate locking underside 217.

(67) A locking rib 221 extends downwardly from the dispensing head 70. The distal end of the locking rib 211 is provided with a locking rib barb 223 having a ramp surface 225 and a locking surface 227. The locking rib 221 and locking rib barb 223 are unitary with the dispensing head 70. At lease one of the arcuate base locking plate 212 and/or the locking rib 221 are formed from a resilient polymeric material.

(68) The locking rib 221 is receivable within the arcuate lock slot 214 defined within the arcuate base locking plate 212. The resilient arcuate lock slot 214 and/or the resilient locking rib 221 are deformed as the locking surface 227 passes through the arcuate lock slot 214. When the resilient arcuate lock slot 214 and/or resilient locking rib 221 return to a non-deformed condition, the locking surface 227 of the locking barb 223 engage an underside 217 of the arcuate base locking plate 212 to prevent separation of the dispensing head 70 from the base 60. The auxiliary latching mechanism 210 prevents separation of the dispensing head 70 from the base 60E while permitting rotation movement of the dispensing head 70 relative to the base 60 and while permitting a tilting and/or downward movement of the dispensing head 70 for actuating the aerosol valve 20.

(69) FIG. 22 illustrates the aerosol spout dispenser 10 being actuated by the depression of the first actuating surface 91 and the alternate second actuating surface 92. The improved aerosol spout dispenser 10 of the present invention provides the advantage of a dual actuation aerosol dispenser. The dual actuation enables a user to have the option of two different forms of actuation. For example, an operator may use the first actuating surface 91 of the dispensing spout 80 for applying a specific product in a one manner using the mechanical advantage to reduce finger fatigue in applying the specific product. However, the same operator may use the second actuating surface 92 of the dispensing head 70 for applying the specific product in a different manner. The different uses of the dual actuation aerosol dispenser of the present invention are too numerous to mention and the immediate advantages of such the dual actuation aerosol dispenser should be readily apparent to those skilled in the art.

(70) FIGS. 23-24 illustrate the aerosol spout dispenser 10 being subjected to a separating force is applied between the dispensing spout 80 and the base 60 and/or the aerosol container 40. The locking surface 227 of the locking barb 223 engage an underside 217 of the arcuate base locking plate 212 to prevent separation of the dispensing head 70 from the base 60. The lever arm of the dispensing spout 80 provides a mechanical advantage for a user to separate the dispensing head 70 from the base 60. The auxiliary latching mechanism 10 inhibits separation of the dispensing head 70 from the base 60 when a separating force is applied between the dispensing spout 80 and the base 60 and/or the aerosol container 40.

(71) FIGS. 25-30 are various views of the aerosol spout dispenser 10 of FIGS. with the dispensing head 70 being located in the locked rotational position and with the dispensing head 70 being in an actuated position. The dispensing head 70 has been rotated counterclockwise relative to the base 60 until the groove rib 183 of the dispensing head 70 engages the unlock position stop 132 of the base 60. During the counterclockwise rotation of the dispensing head 70 from the locked rotational position to the unlocked rotational position, the audible emitting rib 170 of the dispensing head 70 passes over the plural audible ribs 142 and 141, respectively, to provide two independent audible clicks. The audible emitting rib 170 of the dispensing head 70 cooperates with the audible rib 141 to maintain the dispensing head 70 in the unlocked rotational position.

(72) When the dispensing head 70 is located in the locked rotational position, the plurality of groove ribs 181-184 are misaligned with the plurality of grooves 151-154 of the base 60 to inhibit the dispensing head 70 from tilting relative to the base 60.

(73) In the locked rotational position, the dispensing head boss 185 is misaligned with the base notch 155. The dispensing head boss 185 engages with the top portion 61 of the outer ring 100 of the base 60 to prevent the dispensing head 70 from tilting about the bridge 125 to actuate the aerosol valve 20. The engagement of the dispensing head boss 185 with the top portion 61 of the outer ring 100 of the base 60 reinforces the mechanical strength of the substantially flat dispensing spout 80. This reinforcement of the mechanical strength of the substantially flat and horizontal dispensing spout 80 facilitates the shipping of multiple levels of the aerosol spout dispensers 10.

(74) The present invention provides an improved aerosol spout dispenser having a dispensing spout. The aerosol spout dispenser may be actuated either by a depression of the dispensing spout or alternately be actuated by a depression of the dispenser head. The aerosol spout dispenser has a reduced number of parts and preferably a base and a dispensing head. A retainer inhibits separation of said dispensing head from said base when a separating force is applied between said dispensing head and said base. An auxiliary latching mechanism inhibits separation of said dispensing head from said base when a separating force is applied between said dispensing spout and said base. The aerosol spout dispenser includes a lock for inhibiting actuation of the aerosol spout dispenser.

(75) The improved aerosol spout dispenser of the present invention provides several ergonomic advantages over the prior art. The improved aerosol spout dispenser may be actuated on a counter or table top or may be actuated in a hand of a user. The improved aerosol spout dispenser is capable of dispensing product into a hand of a user or directly upon the application surface. The aerosol spout dispenser provides enhanced gripping of the aerosol spout dispenser as well as an unobstructed view of the product delivery.

(76) 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.
