DETAILED DISCUSSION
(118)
(119) The first embodiment of the trigger operated aerosol dispenser 10 defines an axis of symmetry 13 of the trigger operated aerosol dispenser 10. An aerosol valve 20 having a valve stem 30 cooperates with the trigger operated aerosol dispenser 10 to control the flow of the aerosol product 11 from an aerosol container 40.
(120) 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 trigger operated aerosol dispenser 10 of the present invention may be used with aerosol containers of various designs.
(121) As best shown in
(122) 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.
(123) 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.
(124)
(125) 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.
(126) 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 trigger operated aerosol dispenser 10.
(127) 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 trigger operated aerosol dispenser 10. The substantially rigid sidewall 73 of the dispensing head 70 supports a rigid top surface 76.
(128) 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.
(129) A nozzle 80 is located within the dispensing head 70 for communication with the aerosol valve 20. The nozzle 80 includes a nozzle column 81 having a nozzle channel 82 terminating in a socket 84. The socket 84 frictionally receives the second end 32 of the valve stem 30. The nozzle channel 82 is connected to a nozzle passageway 85 terminating in a terminal orifice 86. The nozzle 80 is unitary with the dispensing head 70. The dispensing head 70 may optionally receive a terminal orifice insert 88 defining the terminal orifice 86 for controlling the spray pattern and/or the spray characteristics of the aerosol product 11 including a foaming adapter or a streaming orifice insert.
(130) An important aspect of the present invention is the inclusion of a trigger actuator 90 extending from a proximal end of 91 to a distal end 92. The trigger actuator 90 defines a trigger actuating surface 96 for receiving a finger of an operator (not shown) for actuating the aerosol valve 20 to dispense the aerosol product 11. The proximal end 91 of the trigger 90 is unitary with the dispensing head 70 to move as a one piece unit.
(131) 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 nozzle 80 of the dispensing head 70. The dispensing head 70 has a top surface 76 and a trigger actuating surface 96 to provide two independent actuating surfaces for tilting the dispensing head 70 to dispense the aerosol product 11 from the aerosol container 40.
(132) The dispensing head 70 is rotatable relative to the base 60 between a locked rotational position as shown in
(133)
(134) 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
(135) 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 trigger operated aerosol dispenser 10.
(136) 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.
(137) 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 trigger operated aerosol dispenser 10.
(138) 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
(139) 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.
(140) The trigger operated aerosol dispenser 10 comprises a lock 145 for locking the tilting of the dispensing head 70 relative to the base 60. The lock 145 includes a groove 150 defined on the base 60 cooperating with a groove rib 180 extending from the dispensing head 70. The groove 150 is defined in the inner ring 110 of the base 60 for enabling the dispensing head 70 to the tilted relative to the base 60 as shown in
(141) Referring to
(142)
(143) The dispensing head 70 includes the groove rib 180 extending from the inner surface 75 and the rigid top surface 76 of the dispensing head 70. Preferably, the groove rib 180 is formed as a one-piece unit of the actuator button 70. More specifically, the groove rib 180 includes plural grooves 181-184 equally spaced about the axis of symmetry 13 of the trigger operated aerosol dispenser 10. The groove rib 182 is aligned with the nozzle 80.
(144) 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
(145) The plurality of groove ribs 181-184 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
(146) 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.
(147)
(148) When the dispensing head 70 is moved into the locked rotational position, the nozzle 80 is inhibited from actuating the aerosol valve 20. In the locked rotational position, the plurality of groove ribs 181-184 engage with the inner ring 110 of the base 60 to prevent the dispensing head 70 from tilting relative to the base 60.
(149)
(150) When the dispensing head 70 is located in the unlocked rotational position, the plurality of groove ribs 181-183 are aligned with the plurality of grooves 151-153 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 181-183 with the grooves 151-153 permits the dispensing head 70 to be tilted relative to the base 60 to actuate the aerosol valve 20.

(154)
(155) The improved trigger operated aerosol 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 finger actuating surface 96 of the trigger 90 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 top finger actuating surface 79 of the dispensing head 70 for applying the specific product in a different manner. The following TABLE 1 illustrates some examples of the use of the
(156) TABLE-US-00001 TABLE 1 Product Trigger Actuator Finger Actuator Hairspray Hairstylists - Others Self Sunscreen Body and Back Face Deodorant Body Under Arm Lotions Body Face/Arms Lubricants Large applications Precise Applications Cooking oils Pan Food Fragrances Body Head/Neck Household Large Applications Local Application Surface cleaning Countertops Plumbing fixtures Repellent Body and Back Head Laundry Large Stains Spot Stains Paint spray Large Areas Small Areas
(157) 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.
(158)
(159) The trigger actuator 90 of the dispensing head 70 of the present invention provides several advantages over the prior art. Firstly, the trigger actuator 90 is unitary with the dispensing head 70 to move as a one piece unit. The trigger actuator 90 of the present invention has no lost motion found in many articulated trigger assemblies of the prior art. Secondly, no assembly is required to affix the trigger actuator 90 to the dispensing head 70. Thirdly, the trigger actuator 90 of the present invention exhibits a lower force to actuate relative to the prior art.
(160) TABLE 2 sets forth the force to actuate test for samples of the present invention and competitive example of the prior art.
(161) TABLE-US-00002 Trigger Force Travel Distance UNIT TESTED (pounds) (Inches) Trigger Actuator (Test 1) 2.30 0.040 Trigger Actuator (Test 2) 2.05 0.040 Trigger Actuator (Test 3) 2.30 0.040 Competitor 1 6.95 0.150 Competitor 2 6.65 0.150 Competitor 3 6.70 0.150
(162) Fourthly, the lower force to actuate of the trigger actuator 90 of the present invention results in a reduction of the structures and the material required to provide a functional aerosol dispenser. The trigger actuator 90 of the present invention may be used with a wide variety of aerosol products including personal care products, household products, industrial products, food products, healthcare, automotive and the like.
(163)

The nozzle 80A of the dispensing head 70A defines a nozzle cradle surface 89A. The dispensing head 70A includes an overhang 190A defining an overhang cradle surface 192A. The nozzle cradle surface 89A operates in concert with the overhang cradle surface 192A to provide a hand support for an operator. The index finger (not shown) engages with the nozzle cradle surface 89A with the web (not shown) between the index finger and the thumb engaging with the overhang cradle surface 192A for enabling the hand of the operator (not shown) to ergonomically hold the trigger operated aerosol dispenser 10A. Furthermore, the index finger of the operator is conveniently located to actuate the trigger actuator 90A of the trigger operated aerosol dispenser 10A.
(165)
(166) The aerosol container 40B is shown as a DS container manufactured by the DS Containers of Batavia, Ill. The dispensing head 70B includes a depending skirt 200B extending from the sidewall 74B of the dispensing head 70. The depending skirt 200B is tapered to conform to the contour of the upper portion of the DS container while covering the base 60B.

The distal ends of the locking ribs 221E and 222E are provided with locking barbs 223E and 224E having ramp surfaces 225E and 226E and locking surfaces 227E and 228E. The locking ribs 221E and 222E and locking barbs 223E and 224E are unitary with the dispensing head 70E. At least one of the arcuate base locking plates 211E and 212E and/or the locking ribs 221E and 222E are formed from a resilient polymeric material.
(176) The locking ribs 221E and 222E are receivable within the arcuate lock slots 213E and 214E defined within the arcuate base locking plates 211E and 212E. The resilient arcuate lock slots 213E and 214E and/or resilient locking ribs 221E and 222E are deformed as the locking surfaces 227E and 228E to pass through the arcuate lock slots 213E and 214E. When the resilient arcuate lock slots 213E and 214E and/or resilient locking ribs 221E and 222E return to a non-deformed condition, the locking surfaces 227E and 228E of the locking barbs 223E and 224E engage an underside of the arcuate base locking plates 211E and 212E to prevent separation of the dispensing head 70E from the base 60E.
(177) The auxiliary latching mechanism 210E prevents separation of the dispensing head 70E from the base 60E while permitting rotation movement of the dispensing head 70E relative to the base 60E and while permitting a tilting and/or downward movement of the dispensing head 70E for actuating the aerosol valve 20E.

The lock 145G comprise a base groove shown as a base notch 1500G defined in base 60G cooperating with a groove rib shown as boss 180G defined by the dispensing head 70G.
(182) The base notch 150G is defined in the outer ring 100G of the base 60G and occupies a minor portion of the circumference of the outer ring 100G. Preferably, the base notch 150G occupies a minor portion of the circumference of the outer ring 100G commensurate with the arc portion of the circumference of the bridge 125G. In this example, the base notch 150G occupies a five to ten degree arc portion of the circumference of the outer ring 100G about the axis of symmetry 13G of the trigger operated aerosol dispenser 10G.
(183) The dispensing head boss 180G extends from the outer surface 74G of the dispensing head 70G. Preferably, dispensing head boss 180G is formed as a one-piece unit of the actuator button 70G. More specifically, the dispensing head boss 180G extends in proximity to an underside of the proximal end 91G of the trigger 90G.
(184)
(185) The engagement of the dispensing head boss 180G with the top portion 61G of the outer ring 100G of the base 60G reinforces the mechanical strength of the substantially flat and horizontal top surface 76G. This reinforcement of the mechanical strength of the substantially flat and horizontal top surface 76G facilitates the shipping of multiple levels of the trigger operated aerosol dispensers 10G.
