Definitions

  • TECHNICAL FIELD The present disclosure relates in general to the field of maintaining sanitation using a soap dispenser, and, more particularly, to doing so by marking a person's hands and providing a signal to help coerce effective handing washing.
  • BACKGROUND In a variety of different fields, including businesses and residences, there is a great desire to encourage people to wash their hands more effectively and more frequently.
  • the U.S. Center for Disease Control has stated that the most important thing people can do to keep from getting sick is to wash their hands. And yet, many people, through lack of knowledge, poor habits or simple negligence either do not wash their hands frequently enough or effectively enough.
  • An example of a specific need for assuring sanitized hands is the food services industry. It has been known
  • the timing mechanism is included in the housing for the soap dispenser such that each time the soap dispenser is replaced, the timing mechanism must also be replaced. Additionally, the timing mechanism only provides an indication of a minimum amount of time that a user should wash his hands but does not provide any mechanism to ensure that the user does wash his hands for the minimum amount of time.
  • a hand of a user is marked with an easily identifiable substance during hand washing.
  • a method for helping to assure washing of a person's hands using a soap dispenser containing a cleaning composition includes marking a hand of a user with an easily identifiable substance that can be washed off with the cleaning composition when the soap dispenser is utilized.
  • an apparatus for helping to assure washing of a person's hands includes a soap dispenser and a marking mechanism coupled to the soap dispenser. The marking mechanism marks a hand of a user of the soap dispenser in order to encourage better hand washing.
  • a method for helping to assure washing of a person's hands using a soap dispenser containing a cleaning composition includes identifying a user of the soap dispenser with an identification mechanism and marking a hand of the user with an easily identifiable substance that can be washed off with the cleaning composition when the soap dispenser is utilized.

  • FIGURE 1 is a cross-sectional view of one embodiment of a hand marking soap dispenser.
  • the dispenser includes container 10 for cleaning composition 19.
  • Container 10 has opening 11 defined by threaded male lip 12.
  • Male lip 12 is designed to fit female threaded cap 15 so that cap 15 can be taken on and off to allow container 10 to be filled or refilled
  • Container 10 may be designed to sit substantially flat on a surface such as a table, sink or counter. Container 10 may also be configured (not expressly shown) to mount on a wall or other vertical surface. Additionally, the shape of container 10 may be varied. For use with children, container 10 may be made in the shape of an animal or action hero. In this case, if an audible signal is provided, the audible signal of the device may match the shape of the container. For example, if container 10 is shaped in the form of a frog, an audible signal may provide a crocking noise. Discharge pipe/outlet/hose 14 may be integral to cap
  • discharge pipe 14 may include orifice 18 where cleaning composition 19 exits the dispenser such that cleaning composition 19 is introduced onto a person's hand.
  • discharge pipe 14 may be movable up and down through cap 15 and may be coupled to pump mechanism 16, which may have a spring mechanism and plunger such as those used in liquid dispensers well known in the art.
  • pump mechanism 16 may have a spring mechanism and plunger such as those used in liquid dispensers well known in the art.
  • pump mechanism 16 may be any suitable type of pump used to force liquids out of a container.
  • pump mechanism may be a foaming pump that mixes cleaning composition 19 and air before dispensing cleaning composition 19 through orifice 18.
  • An example of this type of pump is RF-17 Palm Foamer manufactured by Rieke Packaging Systems .
  • Pump mechanism 16 may also be coupled to siphon/suction pipe 17. The up and down motion of discharge pipe 14 associated with pump mechanism 16 may cause cleaning
  • any other mechanism may be used to dispense cleaning composition 19 from container 10.
  • cleaning composition 19 may be dispensed onto a person' s hands by using any type of suitable electronics that allow for marking a person's hand with an easily identifiable substance to assure effective hand washing.
  • the use of pumping mechanisms to dispense a cleaning composition are known in the art and as such various modifications may be made to the exemplary embodiment discussed here in without departing from the spirit of the teachings of the present disclosure.
  • Absorbent pad 13 and compressible protective perimeter 41 may cooperate to form a marking mechanism.
  • Absorbent pad 13 may be any of a number of materials (e.g., felt used for markers or a pad used for stamps) .
  • One commercially available absorbent pad is felt "Fiber Engineered” manufactured by AFFCO of New Windsor, NY.
  • Absorbent pad 13 may include an easily identifiable substance used to mark a hand that comes in contact with absorbent pad 13.
  • Protective perimeter 41 may be shaped compressible foam (or any other suitable compressible material with memory) that surrounds absorbent pad 13 and has a thickness greater than a thickness of absorbent pad 13. If protective perimeter 41 is formed from foam, the foam may be a closed cell foam that will not allow the easily identifiable substance to wick through.
  • Protective perimeter 41 may have any shape such that protective perimeter 41 prevents a user from inadvertently marking clothing, towels and/or other articles that come into contact with the top of discharge pump 14. However, when a user presses down on the top of
  • AUS01: 382143.1 discharge pipe 14 the user's hand first comes into contact with protective perimeter 41 which compresses and allows the user's hand to come into contact with absorbent pad 13. A mark, therefore, may be placed on the user's hand used to press down on discharge pipe 14 and cleaning composition 19 may be dispensed onto the user's other hand.
  • absorbent pad 13 may be removed from discharge pipe 14 such that a new absorbent pad 13 including the easily identifiable substance may be attached to discharge pipe 14 to replace the spent one.
  • attachment mechanism 31 such that the easily identifiable substance may be replenished by removing attachment mechanism 31 and then placing a new one of absorbent pad 13, compressible protective perimeter 41 and/or attachment mechanism 31 on the top surface of discharge pipe 14.
  • Attachment mechanism 31 may include, but is not limited to, double-sided tape, a pressure sensitive adhesive (PSA) , non-permanent adhesive glues and/or gels, a VelcroTM-like material and any other attachment mechanisms that allow for the marking mechanism to be detachably coupled to the top of discharge pipe 14.
  • PSA pressure sensitive adhesive
  • absorbent pad 13 may be kept wet with the easily identifiable substance for a longer period of time by using a reservoir of the easily identifiable substance that is pumped (e.g., a small mechanical pump such as those used to resupply
  • AUS01:382143.1 stamp pads to absorbent pad 13 as the soap dispenser is used.
  • the cleaning composition run out at roughly the same time as the easily identifiable substance runs out (or vice versa) .
  • the marking mechanism includes an absorbent pad
  • absorbent pad 13 starts to run dry as the dispenser runs out of cleaning composition 19. This would allow the user to throw away the entire pre-filled dispenser with the marking mechanism on the top of the pump and buy a new dispenser.
  • absorbent pad 13, protective perimeter 41, attachment mechanism 31 and discharge pipe 14 may be combined into a single integrated unit that both dispenses cleaning composition 19 and also marks a person's hand as the dispenser is utilized.
  • the marking mechanism may also be implemented using a variety of technologies and configurations.
  • the marking mechanism may include any of the marking mechanism types set forth in U.S. Patent Nos. 6,031,461 or 6,211,788.
  • the marking mechanisms may include systems, including but not limited to: (1) mechanical, (2) pneumatic, (3) pneumatic (mechanical) , (4) electronic, and (5) any combination thereof.
  • the marking mechanism may dispense the easily identifiable substance as a spray, micro-dot or mist from separate tubes or nozzles in close proximity to discharge pipe 14.
  • the easily identifiable substance may be discharged on the user's hand concurrently (or approximately concurrently) with the cleaning composition or the easily identifiable substance may be mixed with cleaning composition 19.
  • the easily identifiable substance may be a variety of different types of substances such as those substances set forth in the U.S. Patent Nos. 6,031,461 and 6,211,788. These substances may include inks, dyes, vegetable dyes, paint, stain, pigment, grease and any combination thereof.
  • the easily identifiable substance may also be designed such that it is not easily identifiable visually, but instead is easily identifiable using other detection mechanisms such UV light, or using small metallic substances that are electronically detectable.
  • the easily identifiable substance could further be additional substances such as extremely tiny integrated circuits (sometimes referred to as "smart dust") .
  • the easily identifiable substance may be selected or designed such that the desired type of hand washing is necessitated, once the substance is applied on a hand.
  • the easily identifiable substance may be designed such that it can only be removed by washing it off with cleaning composition 19 (e.g., a liquid soap or a alcohol based composition) and hot or warm water for a sufficient period of time, thereby maximizing sanitation of a person's hands.
  • cleaning composition 19 e.g., a liquid soap or a alcohol based composition
  • One example of an easily identifiable substance may be found in "Care Bears Lite Up Stampers" manufactured by Rose Art, Inc. In a cleansing experiment, the easily identifiable substance applied with the Care Bear stamp came off very slowly (over a minute) with water only, but came off in approximately fifteen (15) to twenty (20) seconds with soap and warm water.
  • Other easily identifiable substances include an aqueous ink which is Food, Drug and Cosmetic approved.
  • One such commercially available ink is a turquoise 1-7054 ink 203-52 manufactured by Ranger Ink. Additional
  • AUS01: 382143.1 commercially available inks or dyes are blue dyes such as l-methyamino-4-o-tolylaminanthanquinone (Blue No. 403, Sudan Blue B) , and violet dyes such as l-hydroxy-4-p- toluinoanthraquinone (Violet No. 201, Arizroll Purple SS) .
  • the easily identifiable substance may be designed such that the easily identifiable substance may be removed by a highly effective anti-germ or anti-bacterial cleaning composition (e.g., an alcohol based cleanser such as Purell manufactured by GOJO) .
  • the mark may be placed in between the fingers on the web of the hand, on the palm of the hand or on the back of the hand. Placement of the mark on a particular part of the hand can be accomplished by use of, for example, finger guides and/or triggers that guide the hand to a desired position prior to marking.
  • the marking mechanism may be designed such that the easily identifiable substance is applied to the hand in a very thin layer (e.g., as accomplished with stamping mechanisms) , thereby maximizing speed of drying and minimizing smearing or staining.
  • Another manner in which to minimize smearing or staining (or to make smearing or staining less of a problem should it occur) is to formulate the easily identifiable substance such that it includes a composition which is easily removable from clothes and other items.
  • U.S. Patent No. 6,147,607 also sets forth various substances which are more easily washable than typical inks, dyes or pigments.
  • the marking mechanism may use, for example, techniques like those disclosed in U.S.
  • FIGURE 2 is a cross-sectional view of another embodiment of a hand marking soap dispenser that includes a signal and/or recording mechanism.
  • the marking mechanism attached to the top of discharge pipe 14 may function similar to the marking mechanism described with respect to FIGURE 1.
  • the illustrated marking mechanism may include absorbent pad 13 that covers the top surface of discharge pipe 14 and does not include a protective perimeter.
  • Signal mechanism 51 and recording mechanism 61 may be activated/triggered when discharge pipe 14 is depressed to dispense cleaning composition 19 such that a person' s hand is marked substantially simultaneously with the easily identifiable substance
  • the soap dispenser may be configured in a variety of ways depending on the desires of the end user. For example it could be configured as follows: (1) a signal mechanism is included but no recording mechanism is included to reduce the cost of the soap dispenser; (2) a recording mechanism is included but no signal mechanism; and (3) both the signal mechanism and recording mechanism are included but either or both may be deactivated or activated as desired by the end user using on/off buttons or switches.
  • signal mechanism 51, recording mechanism 61 and power supply 21 may be associated with container 10.
  • Cover 68 may be coupled with or integral to container 10 to protect signal mechanism 51, recording mechanism 61 and power supply 21.
  • Switch 27 that allows power to flow from power supply 21 to signal mechanism 51 and recording mechanism 61 may be associated with container 10.
  • Switch 27 may be implemented using a variety of technologies including, but not limited to, contact switches, micro-electromechanical switches, pushbutton, toggle, slide, and any other suitable types switches. Accordingly, switch 27 may selectively couple signal mechanism 51 and recording mechanism 61 to power supply 21 via one or more wires 22 or other electrical conduits .
  • switch 27 may be activated by trigger 28 that is coupled with (or integral to) discharge pipe 14. As discharge pipe 14 is depressed to dispense cleaning composition 19, trigger 28 may contact switch 27 and activate signal mechanism 51 and/or recording mechanism 61. Signal mechanism 51 and recording mechanism 61, therefore, may be activated when switch 27 is activated.
  • AUS01:382143.1 Similar to existing soap dispensers, the normal unbiased position of discharge pipe 14 is up (due to springs inside pump 16) . Accordingly, trigger 28 may not be maintained in contact with switch 27 when discharge pipe 14 is in the up position such that signal mechanism 51 and recording mechanism 61 are not activated (e.g., no sound or signal is produced by signal mechanism 51 and no activity is recorded by recording mechanism 61) .
  • the use of switches, power supplies and signal mechanisms capable of generating sounds are known in the art and as such various modifications may be made to the exemplary embodiment discussed here in without departing from the spirit of the teachings of the present disclosure.
  • the marking mechanism operates as a mechanical trigger that activates signal mechanism 51 and/or recording mechanism 61 and also marks the hand of the person pushing down on the absorbent pad 13 containing the easily identifiable substance. Once the easily identifiable substance is placed on a person's hand, it is likely the person will wash his hand to remove the mark. Removing the mark from the one marked hand will typically require the use of the other unmarked hand. The result is two clean hands.
  • signal mechanism 51 may generate a signal that provides information about the desired duration of hand washing. For example, the signal may indicate a minimum period of time that hand washing should occur.
  • the signal may be audible, visual, olfactory, tactile, kinetic or any other suitable type of signal that notifies the user of the soap dispenser of the minimum amount of time needed to wash off the easily identifiable substance.
  • signal mechanism 51 may include a piezo driven by a processor to generate the desired sound. In other embodiments, signal
  • AUS01: 382143.1 mechanism 51 may be any electronic or mechanical components that provide the desired signal.
  • the signal may be activated for approximately fifteen (15) to thirty (30) seconds in order to assure good hand washing to kill germs on the hands.
  • the user therefore, has two entirely different prompts (e.g., the marking mechanism and signal mechanism) that will help assure some minimum period of hand washing.
  • timing information may be provided separate from signal mechanism 51 as opposed to being integrated into signal mechanism 51.
  • a signal is used to coerce use of the marking soap dispenser, people may become accustomed to hearing and/or seeing the signal . As users develop their routine, failure to use the marking soap dispenser and activate signal mechanism 51 becomes obvious to both the intended user and others who expect to hear or see the signal while the employee is in the restroom.
  • the signal or lack thereof may begin to have a Pavlovian response. Accordingly, the signal may transform an essentially voluntary action into an almost reflexive action. As a result, use of the marking soap dispenser and accompanying signal may serve as a sign of cleanliness and hygiene and will comfort others interested in hand washing (e.g. restaurant customers, hospital patients and parents of children) . In addition to the Pavlovian effect (e.g., the signal acts as a reminder to the user to wash her hands) , signal mechanism 51 may also serve as a positive reinforcement. It is possible that children in households would be praised each time they activate the signal when marking their hands with the soap dispenser. For example, the signal could be selected from a menu including a series of different songs, beeps, tones,
  • AUS01:382143.1 directions or noises.
  • the soap dispenser may be placed near a bathroom sink such that the marking mechanism becomes a game for children that teaches them how to wash their hands correctly for the necessary amount of time and with the proper amount of cleaning composition 19 (e.g., the easily identifiable substance will not come off with insufficient hand washing, insufficient cleanser and/or insufficient scrubbing) .
  • signal mechanism 51 may be designed to make a failure to use the subject soap dispenser obvious.
  • the signal may be a light/button (e.g., an LED) and/or audible signal designed to remain on for some period of time after the soap dispenser has been used.
  • this delayed signal may be designed to come on or remain on for some period of time longer than the average user is expected to remain in the area (e.g., approximately one to five minutes after use of the dispenser and/or base) . Therefore, a person entering shortly after the user has left the dispenser area may expect to see or hear the delayed signal. If the signal is designed to stay on for a predetermined period of time, required users of the soap dispenser may not be able to easily bypass the dispenser because the lack of the signal will be obvious to someone entering the area with the dispenser for the predetermined period of time after the desired user has left the area.
  • display window 67 may be included to display information recorded by recording mechanism 61. Display window 67 may be located on the exterior of container 10 and may be maintained in communication with recording mechanism 61 through wires 22. In another embodiment, display window 67 may also be simplified, to lower the cost, to be a light display (e.g., LED) that
  • AUS01: 382143.1 signals use of the dispenser as described above.
  • Information collected by recording mechanism 61 and displayed by display window 67 may include, but is not limited to, how many times the apparatus was activated during a particular period of time, the times of the activation, and frequency of use of the marking soap dispenser, as well as other characteristics associated with the use of the soap dispenser. In this manner, for example, a parent could, at the end of a day, check how often a child had used the marking soap dispenser and the timing of its use. Recording mechanism 61 could be used to see trends in hand washing, reward positive behavior and attempt to change insufficient hand washing. This information may allow a parent (or employer) to monitor hand washing protocol.
  • recording mechanism 61 essentially not only monitors frequency of hand washing but also an effectiveness of hand washing because the mark only comes off with a minimum period and efficacy (e.g., sufficient scrubbing, energy or vigor) of hand washing.
  • Recording mechanism 61 may be implemented using a variety of different technologies, including without limitation, one or more of the following: IC, ASIC,
  • AUS01:382143.1 badges e.g., RFID devices
  • biometrics that allow recording mechanism 61 to differentiate the actions of different persons using the soap dispenser.
  • signal mechanism 51 and/or recording mechanism 61 may be located remotely from the marking mechanism. This configuration may be desirable where a person monitoring hand washing (e.g., restaurant manager or parent of a young child) desires to have the signal and/or recorded information presented at a location other than where the soap dispenser is placed. For example, a parent may not be able to detect the signal from the dispenser if it goes off only in the child's bathroom area.
  • signal mechanism 51 may have a local or remote volume control so that parents (or employers) can change the volume on the signal to their needs.
  • a parent may place one or more remote signal mechanisms in another area of the house such as the kitchen or living room.
  • the remote mechanism may be implemented by hardwiring signal mechanism 51 to a remote location or using one or more wireless technologies.

  • signal mechanism 51 and recording mechanism 61 may be included in base/bottom 70 of the soap dispenser.
  • base 70 may be detachably attached to container 10 so that base 70 may be used with other soap dispensers.
  • a detachable base may allow the detached/remaining soap dispenser to function as a simple soap dispenser without the signal/timing/recordkeeping functionality provided by base 70. This ability to remove the base may be desirable after a child or employee has been adequately trained in hand washing and the person wants to discontinue timing/signaling but still wants to have use of the soap dispenser itself.
