- the power source 180 in the preferred embodiment is a plurality of batteries.
- the batteries are received in a battery pack 182 that is electrically connected to the motor 130 in a conventional manner.
- the power source could be an AC power source or any suitable power source.
- the plate 52 associated with the shroud 16 her includes a mounting wall 192 projecting upwardly from the plate 52 to which a switch 194 is mounted.
- the switch 194 is electrically connected to the motor 130 and the power source 180 in a conventional manner.
- the switch 194 Is activated by a trigger assembly that includes a switch actuator 196 .
- the switch actuator 196 includes a U-shaped member 198 , an upward projection 202 , and a downward L-shaped projection 204 .
- the U-shaped member 198 surrounds the neck 34 of the container 12 .
- the U-shaped member 198 mounts on fulcrums 208 extending upwardly from the plate 52 .
- the downward L-shaped projection 204 limits the pivotal movement of the switch actuator 196 by contacting the front wall 18 of the container 12 . As more clearly seen in FIG. 7 , the downward L-shaped projection 204 is spaced slightly from the front wall 18 of the container 12 .
- the switch 194 is designed to activate with minimal force so that the switch actuator 196 need only to be barely depressed before the pump is actuated.
- the trigger assembly also includes a trigger pad 212 that mounts to the switch actuator 196 over the L-shaped projection 204 .
- the trigger pad 212 provides a rounded surface that complements the back of a user's hand or fingernail such that slight depression on the trigger 212 will result in the deposit of the household liquid on the upward facing palm of the user. Lateral force against the trigger pad 212 also activates dispensing.
- the housing 14 or the shroud 16 can limit the movement of the switch actuator 196 .
- a consumer depresses the trigger pad 212 with the downwardly facing surface of a cupped hand causing the L-shaped projection 204 of the switch actuator 196 to rotate slightly on the fulcrums 208 about an axis defined at the intersection of the L-shaped projection 204 and the U-shaped member 198 .
- the switch actuator 196 Upon rotation of the switch actuator 196 , the end of the U-shaped member 198 is forced upwardly closing the switch 194 . With the switch closed, the circuit between the motor 130 and the power source 180 is closed; therefore, power is delivered from the power source to the motor. When the user has enough soap, the hand is raised and dispensing ceases.
- trigger assemblies can be used to activate the trigger assembly, including an optical sensor and other known mechanisms.
- shape of the trigger can be modified.
- the trigger pad is adapted to be depressed by the back of the user's hand.
- the shape of the trigger can be modified.
- the trigger assembly is positioned below the outlet of the nozzle 74 such that the hand or object used to depress the trigger pad 212 is in position to receive the household liquid.
- the soap dispenser provided allows the user to lightly depress the trigger pad with the back of the user's finger to dispense the soap. This remedies the problem of requiring the user to depress a hand pump with a dirty hand. Since the back of one's hand is usually not soiled, dirt will not likely be deposited on the trigger when the trigger is depressed. The amount of force required to activate the trigger and thus the switch is much smaller than the amount of force required to depress the hand pump of a conventional hand soap pump. Accordingly, less dexterity is needed to use the motorized dispenser than a conventional hand pump soap dispenser.
- the dispenser can be used to deposit dishwashing soap onto a dirty plate, pot or pan. In such a case, the user can depress the trigger pad with the dirty plate, pot or pan and the plate, pot or pan is positioned to receive the dishwashing soap.

Hence, specific examples of characteristics relating to the embodiments disclosed herein are not to be considered as limiting.
- Referring now to
FIGS. 1 and 2 , a motorizedhand soap dispenser 10 includes acontainer 12, ahousing 14 positioned behind thecontainer 12, and ashroud 16 positioned above the container and the housing. Generally, the container stores a liquid, the housing encloses mechanical and electrical components, and the shroud covers a conduit for the liquid. For ease of explanation of the figures only, and not to limit the invention to only that described, the terms “front,” “rear,” “top,” and “bottom,” and the like will be used to describe the figures; however, such terms are simply to describe the figures and not to limit the invention to the embodiments described. - The
container 12 stores a household liquid such as hand soap, dishwashing soap, shampoo, conditioner and the like. The container can be made of plastic or another durable material. With reference toFIG. 3A , the container includes afront wall 18, arear wall 22, andside walls front wall 18 in the preferred embodiment is rounded or arcuate for an aesthetically pleasing appearance; however, the front wall can be another suitable shape. Therear wall 22 is substantially flat or planar. Theside walls rear wall 22. The rear wall thus defines an indented central portion or notch. The container further includes atop wall 28 and abase wall 32. Aneck 34, which in this embodiment is circular, is positioned on thetop wall 28 and defines anopening 36. A container seal 38 (FIG. 3B ) can be positioned in thecircular neck 34. Thebase wall 32 has a central indented portion, as seen inFIG. 7 . - A pump assembly draws the household liquid from the
container 12. Referring toFIG. 3B , the pump assembly includes adip tube 42, apump diaphragm 44, and anexhaust tube 46. Thepump diaphragm 44 is disposed in apump housing 48. Thedip tube 42 communicates with thepump diaphragm 44 which includes a pump chamber (not visible) that communicates with theexhaust tube 46 to draw liquid out of the container. Thedip tube 42 can include an intake check valve (not shown). The intake check valve can be positioned anywhere upstream of the pump chamber. Theexhaust tube 46 can also include an exhaust check valve (not shown); however, the exhaust check valve can be positioned anywhere downstream of the pump chamber. Alternatively, a single check valve can be disposed in the pump diaphragm. Thepump diaphragm 44 and thepump housing 48 can compromise a positive displacement pump similar to a traditional hand soap pump powered by a user depressing on a nozzle. - A
disc 50 attaches to a plate 52 (FIG. 3A ) to sandwich the top of thediaphragm 44 and thepump housing 48 between the two. Thediaphragm 44 is thus retained in a closed volume defined by thepump housing 48 and thedisc 50. Thedisc 50 includes anopening 54 that receives theexhaust tube 46. Theexhaust tube 46 moves up and down inside theopening 54. Thedisc 50 further includesapertures 56 that receive fasteners 58 (FIG. 3A ), which are received inapertures 60 in theplate 52 to attach the disc to the plate. The plate includes anopening 62 to receive thepump housing 48. Theplate opening 62 surrounds theneck 34 of the container and aligns with thecontainer opening 36 such that the pump housing can be received in thecontainer 12. Theplate 52 is attached to theshroud 16 so that when the shroud is lifted the pump assembly is removed from thecontainer 12. The plate includesholes 64 that align with holes 66 (only one shown inFIG. 7 ) in theshroud 16. Theholes conventional fasteners 68 fixing the plate to theshroud 16. - Referring back to
FIG. 3B , theexhaust tube 46 slides up and down in thedisc opening 54 working aplunger 70 which is part of thepump diaphragm 44. Theplunger 70 is the working member for the pump assembly. Anozzle 72 is received by theexhaust tube 46. Thenozzle 72 includes about a 90 degree bend. Thenozzle 72 attaches to anozzle extension 74, which provides anoutlet 76 for the household liquid. In use, the household liquid is drawn through thedip tube 42 into the pump chamber of thepump diaphragm 44 and through theexhaust tube 46, thenozzle 72 and finally thenozzle extension 74 before reaching theoutlet 76 at the distal end of the nozzle extension. - The
exhaust tube 46 and thus the pump assembly, is driven by a pump actuator 80 (FIG. 3B ). Thepump actuator 80 includes a horseshoe shaped member 82 having a receivingslot 84 around the inner surface of the horseshoe shaped member that receives anapron 86 of theexhaust tube 46. Thepump actuator 80 is driven by a motor and transmission assembly contained in thehousing 14. Thehousing 14 is seen in an exploded view inFIG. 3A . - The
housing 14 can be made of plastic or another suitable material. Thehousing 14 includes a front orfirst panel 90 and a rear orsecond panel 92. Thefront panel 90 and the containerrear wall 22 are complementarily shaped such that thefront panel 90 is shaped to be received in the central indented portion or notch defined by theside walls rear wall 22 of thecontainer 12. In the embodiment depicted inFIGS. 1 and 2 , thefront panel 90 includes a planar portion that abuts therear wall 22 of thecontainer 12. Other complementary shapes are contemplated, including those depicted inFIGS. 4A, 5 and 6. - The
front panel 90 includes afight side wall 94 and aleft side wall 96. Theright side wall 94 is a mirror image of theleft side wall 96. The side walls havelower side notches 98 having front tabs 100 (only one visible inFIG. 3 ) positioned in the notches. Therear panel 92 includeslower side flanges 102 having rear tabs in 104 (only one shown). Thelower side flanges 102 are resilient such that therear tabs 104 fit over thefront tabs 100 to attach thefront panel 90 to therear panel 92. Therear panel 92 also includesupper tabs 106 at its top that fit into a mating portion of theshroud 16. - A
latch plate 108 is provided to hold thecontainer 12 in a fixed relation to thehousing 14. Both thefront panel 90 and therear panel 92 includenotches latch plate 108. Referring toFIG. 7 , thelatch plate 108 includes a protrusion ortongue 114 that is received in a depression orgroove 116 in thebase wall 32 of thecontainer 12. As is also noticeable fromFIG. 7 , the bottom of thelatch plate 108 is level with the bottom most portion of thebase wall 32 of thecontainer 12, so that thedispenser 10 can sit level on a surface. - Referring back to
FIG. 3A , the front panel also includes adeep notch 118 defined by two upwardly extendingprojections 120, which are mirror images of one another. The pump actuator 80 (FIG. 3A ) is received in thedeep notch 118. Theactuator 80 includes two side channels 122 (only one shown) that slide along theprojections 120. The pump actuator reciprocates up and down in thenotch 118 to drive the pump assembly. Theprojections 118 are received inside anopening 124 in the plate 52 (FIG. 3A ), which secures thefront panel 90 firmly behind therear wall 22 of thecontainer 12. - As mentioned earlier, a
motor 130 through a plurality of gears drives thepump actuator 80. Themotor 130 drives apinion 132. Thepinion 132 drives a firstintermediate gear 134. A first intermediate pinion 136 (FIG. 7 ) is attached to the firstintermediate gear 134, and is driven along with the first intermediate gear. The firstintermediate pinion 136 drives a secondintermediate gear 138. The secondintermediate gear 138 has a second intermediate pinion 140 (FIG. 7 ) attached to and driven along with the second intermediate gear. The second intermediate pinion 140 drives a thirdintermediate gear 142. The thirdintermediate gear 142 has a thirdintermediate pinion 144 attached to and driven along with the third intermediate gear. The thirdintermediate pinion 144 drives adrive gear 146 WIG. 3B). - The
drive gear 146 includes ahole 148 offset from its center. Apin 150 is mounted in thehole 148 and cares an inner sleeve 152 and anouter sleeve 154. Thepin 150 engages aslot 156 in the pump actuator. The pin and slot converts the rotational movement of thedrive gear 146 into reciprocating movement of theactuator 80. In an alternative embodiment, such a mechanism can include a rack and pinion; however, a reversing electric motor would be used. Other conventional mechanisms can be used to convert the rotational movement into a reciprocal movement. The transmission disclosed is a gear reduction transmission that translates the high RPM output of themotor 130 to a lower RPM rotation for thedrive gear 146, other conventional transmissions can also be used to drive the pump actuator - The
intermediate gears front gear plate 158 and arear gear plate 160. Thefront gear plate 158 includesaxle openings 162 that are aligned withaxle openings 164 in therear plate 160.Axles 166 are received in theopenings front gear plate 158 and therear gear plate 160. Therear gear plate 160 includes an additional axle opening at its top 168 that receives afastener 170 for thedrive gear 146. Therear gear plate 160 also includes apinion opening 172 through which thepinion 132 protrudes. Aspacer 174 andbushings 176 can be provided to appropriately space the gears between thefront gear plate 158 and therear gear plate 160. - The
motor 130 receives power from apower source 180. Thepower source 180 in the preferred embodiment is a plurality of batteries. The batteries are received in abattery pack 182 that is electrically connected to themotor 130 in a conventional manner. In an alternative embodiment, the power source could be an AC power source or any suitable power source. - The
plate 52 associated with the shroud 16 (FIG. 3A ) her includes a mountingwall 192 projecting upwardly from theplate 52 to which aswitch 194 is mounted. Theswitch 194 is electrically connected to themotor 130 and thepower source 180 in a conventional manner. Theswitch 194 Is activated by a trigger assembly that includes aswitch actuator 196. Theswitch actuator 196 includes aU-shaped member 198, anupward projection 202, and a downward L-shapedprojection 204. TheU-shaped member 198 surrounds theneck 34 of thecontainer 12. TheU-shaped member 198 mounts onfulcrums 208 extending upwardly from theplate 52. The downward L-shapedprojection 204 limits the pivotal movement of theswitch actuator 196 by contacting thefront wall 18 of thecontainer 12. As more clearly seen inFIG. 7 , the downward L-shapedprojection 204 is spaced slightly from thefront wall 18 of thecontainer 12. Theswitch 194 is designed to activate with minimal force so that theswitch actuator 196 need only to be barely depressed before the pump is actuated. The trigger assembly also includes atrigger pad 212 that mounts to theswitch actuator 196 over the L-shapedprojection 204. Thetrigger pad 212 provides a rounded surface that complements the back of a user's hand or fingernail such that slight depression on thetrigger 212 will result in the deposit of the household liquid on the upward facing palm of the user. Lateral force against thetrigger pad 212 also activates dispensing. In an alternative embodiment, thehousing 14 or theshroud 16 can limit the movement of theswitch actuator 196. - In use, a consumer depresses the
trigger pad 212 with the downwardly facing surface of a cupped hand causing the L-shapedprojection 204 of theswitch actuator 196 to rotate slightly on thefulcrums 208 about an axis defined at the intersection of the L-shapedprojection 204 and theU-shaped member 198. Upon rotation of theswitch actuator 196, the end of theU-shaped member 198 is forced upwardly closing theswitch 194. With the switch closed, the circuit between themotor 130 and thepower source 180 is closed; therefore, power is delivered from the power source to the motor. When the user has enough soap, the hand is raised and dispensing ceases. - Other trigger assemblies can be used to activate the trigger assembly, including an optical sensor and other known mechanisms. Furthermore, the shape of the trigger can be modified. In the particular embodiment described above, the trigger pad is adapted to be depressed by the back of the user's hand. In other embodiments, perhaps where the bottle is storing a liquid that is different from hand soap, the shape of the trigger can be modified.
- The trigger assembly is positioned below the outlet of the
nozzle 74 such that the hand or object used to depress thetrigger pad 212 is in position to receive the household liquid. In one embodiment, the soap dispenser provided allows the user to lightly depress the trigger pad with the back of the user's finger to dispense the soap. This remedies the problem of requiring the user to depress a hand pump with a dirty hand. Since the back of one's hand is usually not soiled, dirt will not likely be deposited on the trigger when the trigger is depressed. The amount of force required to activate the trigger and thus the switch is much smaller than the amount of force required to depress the hand pump of a conventional hand soap pump. Accordingly, less dexterity is needed to use the motorized dispenser than a conventional hand pump soap dispenser. Furthermore, the dispenser can be used to deposit dishwashing soap onto a dirty plate, pot or pan. In such a case, the user can depress the trigger pad with the dirty plate, pot or pan and the plate, pot or pan is positioned to receive the dishwashing soap. - Referring to
FIGS. 4A and 413 , an alternative embodiment of adispenser 310 is disclosed. Thedispenser 310 includes acontainer 312, ahousing 314 and ashroud 316. Thecontainer 312 stores a household liquid, similar to thecontainer 12 disclosed above. Thecontainer 312 includes a mountingportion 318 that includes twotongues 322, one on each side. The container also includes a neck (not visible) that defines an opening (not visible). A container seal 324 mounts to the neck and includes an opening 326 that aligns with and communicates with an opening (not visible) in thehousing 314, - The pump assembly, drive mechanism and power supply used to drive the pump assembly is similar to that described above in FIGS. 3SA and 3B.

FIG. 5 , the pump assembly with the exception of adip tube 328 is disposed in thehousing 314 orshroud 316. Thedip tube 328 is received in the opening 326 of the container seal 324 and communicates with the pump assembly via the opening (not visible) in thehousing 314 orshroud 316. - The
housing 314 can be made of plastic or another durable material. In this embodiment, thehousing 314 and theshroud 316 are a unitary structure; however, in an alternative embodiment, theshroud 316 can be a separate component from thehousing 314. The housing includes a mountingportion 332 that receives the mountingportion 318 of thecontainer 312. In this embodiment, the mountingportion 332 of thehousing 314 is shown at a side of thehousing 314, but the mounting portion can be positioned elsewhere, such as at the rear of thehousing 314. The mountingportion 332 of thehousing 314 includes two grooves 334 (only one is visible) that receive the twotongues 322 of thecontainer 312. Thehousing 314 can also include a removable wall (not shown) to provide access to the power source. - Referring to

The conventional pump bottle A includes a container for storing liquid hand soap, a pump (not shown) disposed in the container for pumping the hand soap out of the container, a pump driving member and an outlet for the hand soap. The pump driving member for the pump bottle A depicted in the figures is the nozzle of the pump bottle, which normally a user depresses with one hand to dispense the liquid soap from inside the container onto his other hand. - The
housing 602 includes aplatform 608 upon which the bottom of the pump bottle A rests, as seen inFIGS. 10 and 11 . Theplatform 608 is generally rectangular to complement the bottom of the container of the pump bottle A. Asmall projection 610 extends upwardly from an end of theplatform 608. Projecting upwardly from theplatform 608 and spaced from theprojection 610, ahousing front wall 612 along with a housingrear wall 614 enclose the major mechanical and electrical components of thedispensing apparatus 600. Theprojection 610 and thefront wall 612 are spaced such that the container of the pump bottle A can be received on theplatform 608. Attached to thefront wall 612, twoupper side walls 616 project outwardly and cover an upper portion of the pump bottle A (FIGS. 10 and 11 ). Theside walls 616 are spaced from theplatform 608 such that the side walls cover a top wall of the container of the pump bottle A. Referring toFIG. 10 , the housing includes atop wall 622 having an opening 624. The front of thehousing 602 is substantially open, as noticeable from the figures. - The
actuator assembly 604 drives the pump of the pump bottle. Referring toFIG. 10 , the actuator assembly includes arod 626 that is received in the opening 624 in thetop wall 622 and afollower 628 attached to an end of therod 626. Therod 626 is driven by a motor and transmission similar to that described with reference toFIG. 3A , and therefore for the sake of brevity will not he described in much detail. Basically, a motor through a gear reduction transmission that translates the rotational movement of the motor into a reciprocating motion of theactuator assembly 604 drives therod 626. The motor is powered by a conventional power source, including batteries and/or a plug that can fit into a wall receptacle. The motor, transmission and batteries are enclosed by thefront wall 612 and therear wall 614 of thehousing 602. - The
follower 628 engages a portion of the nozzle of the pump bottle A to drive the nozzle up and down, thus dispensing liquid soap from the container. Thefollower 628 can engage the nozzle in any conventional manner that allows the nozzle to travel along with the follower. For example, the follower can include a U-shaped member that receives an underside of the nozzle to pull the nozzle up on an upstroke, and a portion of the follower can push the nozzle down on a downstroke. Similarly, thefollower 628 can simply depress the nozzle on its downstroke and the nozzle can return due to the biasing action provided by a spring (not shown) in the pump of the pump bottle A. This biasing is the usual action of a conventional retail soap bottle pump where the user of which depresses the nozzle to dispense soap. - The
trigger assembly 606 actuates theactuator assembly 604. Thetrigger assembly 606 includes atrigger 632 having atrigger pad 634 formed at a distal end of the trigger. Thetrigger 632 mounts to thehousing 602 above theplatform 608 and below thefollower 628 on the same side of thehousing 602 as the platform. Thetrigger 632 also includes a pair ofarms 636 that attach to thehousing 602. Thetrigger arms 636, thetrigger 632 and thefront wall 612 of thehousing 602 define an opening 638 (FIG. 9 ) through which the pump bottle A is received. Theopening 638 is shaped similarly yet slightly larger than the container of the pump bottle A. In this embodiment, theopening 638 is substantially rectangular and slightly larger than theplatform 608. Thetrigger 632 mounts to thehousing 602 by use of anaxle 642. - The
trigger assembly 606 closes a switch similar to the trigger assembly described with respect toFIG. 3A . Thetrigger 632 pivots about theaxle 642 in response to a downward and/or lateral force on the trigger. Theaxle 642 can pivot such that a portion of the axle contacts a switch that closes the circuit between the power source and the motor. Thetrigger 632 can close the switch in other conventional manners. Upon depression of thetrigger pad 634, theactuator assembly 604 drives the nozzle of the pump bottle A to dispense hand soap. Thetrigger 632 is positioned under the nozzle outlet of the pump bottle A when the pump bottle is received by thehousing 602. Accordingly, the same hand that activates thetrigger 632 is also in position to receive a dose of liquid hand soap. Furthermore, since thetrigger 632 is pivotally mounted and the nozzle is mechanically driven, a smaller force is needed by the user to activate thedispensing apparatus 600 than is required to dispense liquid soap from the pump bottle A in a conventional manner. Also, the back of the handwasher's hand, which is usually not soiled, can be used to activate thetrigger 632. A small force is used to activate thetrigger 632 and the trigger is limited in is rotation by the container of the pump bottle A. - Accordingly, a dispenser that fulfills all of the above-mentioned objectives has been provided. The invention has been described with reference to preferred embodiments. Obviously) modifications and alterations will occur to others upon reading and understanding the proceeding detailed description.
