Definitions
- Exemplary embodiments relate to dispensers providing a convenient method for applying hand sanitizer.
- the Centers for Disease Control issued seven recommendations to the general public of the U.S. on Mar. 27, 2020.
- the first recommendation cited was to wash your hands frequently.
- the second one cited was to “avoid touching your eyes, nose, and mouth with unwashed hands.”
- Other recommendations were manageable such as keeping a six-foot distance between persons and wearing a face mask. Washing one's hands however can be quite problematic when performing functions in public such as shopping and traveling to work. Every door, shopping cart, gas pump handle, subway hand grip and elevator button could conceivably be contaminated with COVID-19 or other pathogens.
- Alcohol-based disinfectants have been found to be an effective way of eliminating pathogens such as COVID-19.
- Hand disinfectants are marketed in a range of viscosities from 95% alcohol (liquid) to gel-based mixtures.
- the gel-based disinfectants may have a viscosity up to 300 times that of pure ethyl alcohol when mixed with 35% glycerin to 65% alcohol, so a dispenser with broad utility may be needed to accommodate a large range of viscosities.
- Exemplary embodiments provide a dispenser providing a convenient method for applying hand sanitizer.
- Exemplary embodiments also provide a wrist-worn dispenser providing a convenient method for applying hand sanitizer.
- a dispenser includes a reservoir having a first sheet and a second sheet connected at edges thereof, and a dispensing aperture arranged between the first sheet and the second sheet.
- a dispenser includes a holster having a first ply and a second ply, a reservoir having a first sheet and a second sheet connected at edges thereof, and a dispensing aperture arranged between the first sheet and the second sheet, wherein the second ply forms a pocket on the first ply, and the reservoir is arranged in the pocket between the first ply and the second ply.
- a clip includes a body having a tubular shape and a channel formed through the body and extending along an entire length thereof.

- FIG. 16 a , FIG. 16 b , FIG. 16 c and FIG. 16 d show a method for installing a valve into a bladder according to an exemplary embodiment.
- the dispenser 10 includes a holster 1 to allow the dispenser to be wrist-worn, for dispensing sanitizer.
- the holster 1 may be made of a synthetic or natural fabric or plastic sheet and secured to a user's wrist using a buckle 3 and hook 21 and loop 20 fastener.
- a valve 2 extends from the holster 1 and may be directed towards the user's palm of hand.
- the holster 1 has a bladder 4 arranged therein.
- the bladder 4 is shown in FIG. 2 and FIG. 3 .
- the body of the bladder 4 is fabricated from two plies of sheet plastic such as polystyrene of polypropylene and is heat welded together at a seam 5 .
- the bladder may also be fabricated using a blow mold technique.
- the bladder 4 is a two-ply, heat welded six mil polypropylene material capable of containing fifteen cubic centimeters of hand sanitizer fluid of varying viscosity.
- the bladder 4 provides a contained environment using a check valve-controlled, dispensing duct at one end thereof, and a refill opening 37 at the opposite end thereof.
- the valve 2 is secured to the bladder 4 using shrink wrap tubing 8 compressed over the bladder plies, forcing them into a groove located on the valve body (described below with respect to FIGS. 5-7 b and 16 a - 16 d ).
- the bladder 4 has a flap 6 , and a clip 7 is slid over the flap 6 to secure and seal the bladder 4 opening 37 .
- FIG. 3 demonstrates how the bladder 4 is filled with fluid according to the present exemplary embodiment.
- the clip 7 is removed from the flap 6 of the bladder 4 .
- the flap 6 is unfolded and separated to expose the opening 37 .
- the sides of the bladder 4 are then squeezed using the thumb and index finger placed on the edges of the bladder 4 in order to expand the bladder 4 .
- Sanitizer is then pumped into the bladder 4 to a level approximately two-thirds of the way up using a bottle with pump 9 .
- the flap 6 is closed by folding the flap 6 back on itself twice with each fold being approximately one quarter inch in width.
- the clip 7 is then reinstalled by sliding it from one side and across the seam of the bladder 4 .
- the clip 7 is made of a plastic material such as polyoxymethylene (acetal).
- a channel 11 is cut in the clip 7 and notched 12 at both ends of the clip 7 to facilitate insertion onto the flap 6 .
- a label embossed or stamped may carry brand, writing or technical information.
- the clip 7 may be used for restraining any multiple-ply sheet material such as tooth paste or cosmetic tubes to prevent the paste from moving away from the nozzle when being squeezed.
- the valve 2 is a pressure valve having a body made of polyoxymethylene and that includes a polyoxymethylene ball 13 and a spring 17 .
- Ball diameter and properly adjusted spring force is used to realize the optimal pressure required to release fluid to a user's hand.
- the valve 2 pressure release mechanism may alternatively be made of a cross-slotted diaphragm or other technique that would restrict the flow of sanitizer fluid until a critical pressure level is obtained.
- the spring constant and aperture permits a reasonable pressure be applied in order to release the sanitizer without the problem of unintended release, slow weep or discharge requiring excessive applied pressure.
- a cap 16 that contains a properly sized hole capable of retaining the ball 13 , is affixed to the valve 2 body using a heat crimp 14 or cyanoacrylate adhesive.
- the valve 2 is adhered to the bladder 4 with the use of grooves 15 a and 15 b in the valve 2 that permits the unification of the bladder 4 to valve 2 using shrink tubing. This approach helps insure that no leakage takes place when pressure is exerted on the bladder 4 , such as by using the fingers of an opposing hand.
- a vent 18 communicates fluid from bladder 4 to a user's palm.
- FIG. 7 a and FIG. 7 b are cross-sectional views of the valve 2 as shown in FIGS. 5 and 6 according to the present exemplary embodiment.
- a valve inlet chamber 16 a is provided between the ball 13 and the valve chamber wall to allow fluid to pass when pressure is applied to the bladder 4 during operation, as shown in FIG. 7 b .
- the spring 17 was chosen with a k value (i.e., force rate) commensurate with the desired pressure to release the sanitizer fluid.
- the length of the spring 17 along with the length of the spring chamber allows adjustment of the spring tension to fine tune the optimal pressure release point.
- the spring 17 has a compressed length greater than spring chamber length, which is intended to prevent a situation where a solid height (i.e., all windings compressed upon each other) may be reached causing restriction or stoppage of the fluid through the valve 2 , such as by the ball 13 blocking fluid from flowing through the spring chamber.
- Groove 15 a is used in concurrence with the cap 16 allowing the cap to be sealed to the valve body using a heat crimp.
- Groove 15 b performs two functions. First, it provides a pressure seal between the valve 2 and bladder 4 (as described with respect to FIGS. 16 a -16 d below) and second, it prevents the valve from moving back into the bladder 4 , such as if the valve 2 is inadvertently forced backwards.
- FIG. 8 is a top view of the holster 1 showing the hook 21 and loop 20 fastener.
- FIG. 9 is a bottom view of the holster 1 having a pocket 23 sewn thereon, the hook 21 affixed on a tapered end of the holster 1 , and a buckle 3 affixed on the opposite end of the holster 1 .
- the holster 1 is secured to a user by threading the holster 1 through a “D” ring of the buckle 3 and securing it with the hook 21 to the loop 20 sewn on the top side of the holster 1 .
- the pocket 23 is accessed by a first opening 22 about one-third of the way down the pocket 23 , the first opening 22 perpendicularly orientated to the buckle 3 .
- the pocket 23 also has a second opening 24 along the bottom edge of the holster 1 for the valve 2 to be exposed therethrough.
- the bladder 4 is inserted into the pocket 23 , and may be completely enclosed in the pocket 23 .
- FIG. 10 is a view of the bottom side of the holster 1 with the bladder 4 overlaid on the holster 1 to show the area that the bladder 4 occupies in the pocket 23 .
- FIG. 11 The method for dispensing hand sanitizer fluid onto the palm of a user's hand is shown in FIG. 11 .
- a user's hand from the arm opposite of the arm having the wrist on which the dispenser 10 is attached, is placed over the holster 1 and pressed with a force that causes fluid 26 to expel from the valve 2 and onto the user's palm.
- the dispenser 10 may be attached on either wrist.
- the bladder 4 having a 15 cc capacity provides, at a minimum, a one day supply. Also, the bladder 4 is easy to replace or refill in situ without the use of special tools. To accomplish this, the bladder 4 is configured as a separable unit from the holster 1 . Individual bladders can be carried or stored for later use.
- a dispenser 100 according to an exemplary embodiment is shown in FIG. 12 and FIG. 13 .
- the dispenser 100 may be substantially the same as the dispenser 10 described above with respect to FIGS. 1 through 11 of the present application, and the disclosure thereof is incorporated herein by reference, and any repeated disclosure may be omitted for the sake of brevity.
- the dispenser 100 may be disposed after a single use, or when the reservoir therein is depleted.
- a base ply 27 is made from low-cost felt, paper/fiber, or personal protective equipment (PPE) material.
- PPE personal protective equipment
- a bladder pack 28 is completely sealed after being filled, eliminating a refill capability (such as described above with respect to the bladder 4 ), and the bladder pack 28 is positioned on the top side of the base ply 27 .
- a buckle 31 is made of a low-cost material such as plastic or steel.
- An attachment mechanism 30 may be hook and loop or a fastener similar to what is used on ACETM bandages.
- FIG. 14 shows a dispenser 200 according to an exemplary embodiment having a different method of attachment to a user than the dispenser 10 and dispenser 100 .
- the dispenser 200 may be substantially the same as the dispensers 10 and 100 described above with respect to FIGS. 1 through 13 of the present application, and the disclosure thereof is incorporated herein by reference, and any repeated disclosure may be omitted for the sake of brevity.
- An outer band 32 is made of a spandex-type material attached to the ends of a pocket 33 made of non-stretchable fabric.
- a bladder pack 28 (or bladder 4 , not shown), as described above, is arranged on the pocket 33 .
- FIG. 15 shows the dispenser 200 with a pocket cover 35 and expandable retainer 36 .
- the bladder pack 28 is disposed in a pouch formed between the pocket 33 and the pocket cover 35 .
- the retainer 36 is connected to the pocket 33 and may be expanded or contracted to retain the bladder pack 28 in the pouch.
- the dispenser 200 is reversible, whereby a pouch opening, for inserting and removing the bladder pack 28 , may be arranged on the inside of the dispenser 200 , closer to a user's wrist.
- FIG. 16 a , FIG. 16 b , FIG. 16 c and FIG. 16 d show a method for installing a valve 2 into a bladder 4 according to an exemplary embodiment.
- the valve and bladder are substantially similar to the valve and bladder described above with respect to the exemplary embodiment shown in FIGS. 1-7 b , and the description thereof is incorporated herein by reference, and any repeated description thereof is omitted.
- the description herein with respect to FIGS. 16 a -16 d is incorporated by reference in the exemplary embodiment shown with respect to FIGS. 1-7 b .
- the method according to the present exemplary embodiment assures an adequate seal between bladder 4 and valve 2 , thereby preventing leakage during use.
- a round tipped dowel 41 with a diameter of 0.230 inch is forced through a channel 40 in order pre-stretch the channel prior to insertion of the valve 2 , as shown in FIG. 16 a .
- the valve 2 is seated using a second tool 42 .

Description
- This application is a continuation of U.S. patent application Ser. No. 17/128,332, filed on Dec. 21, 2020, which claims benefit of U.S. Provisional Patent Application No. 63/053,063, filed on Jul. 17, 2020, and which are hereby incorporated by reference for all purposes as if fully set forth herein.
- Exemplary embodiments relate to dispensers providing a convenient method for applying hand sanitizer.
- The emergence of the COVID-19 viral pandemic within the United States, in January 2020, revealed shortcomings of personal protective equipment as well as agreed upon guidance regarding proper hygienic measures to protect oneself from contraction of the virus.
- The Centers for Disease Control issued seven recommendations to the general public of the U.S. on Mar. 27, 2020. The first recommendation cited was to wash your hands frequently. The second one cited was to “avoid touching your eyes, nose, and mouth with unwashed hands.” Other recommendations were manageable such as keeping a six-foot distance between persons and wearing a face mask. Washing one's hands however can be quite problematic when performing functions in public such as shopping and traveling to work. Every door, shopping cart, gas pump handle, subway hand grip and elevator button could conceivably be contaminated with COVID-19 or other pathogens.
- Although normal in other countries, the use of face masks in the U.S. was not customary until recently. The lowering of this barrier, due to possible infection, has not only been encouragement for all to wear a mask, it has been seen as respectful to others who may come in close proximity to the wearer. However, touching one's face may result from an involuntary response to itch, sweat, dry an eye, or a need to adjust ones glasses or face mask. Keeping a six foot distance, wearing a mask, and washing ones hands is a voluntary action but may not sufficiently reduce the chance of tainting the face with contaminated hands.
- Alcohol-based disinfectants have been found to be an effective way of eliminating pathogens such as COVID-19. Hand disinfectants are marketed in a range of viscosities from 95% alcohol (liquid) to gel-based mixtures. The gel-based disinfectants may have a viscosity up to 300 times that of pure ethyl alcohol when mixed with 35% glycerin to 65% alcohol, so a dispenser with broad utility may be needed to accommodate a large range of viscosities.
- Members of the general public may rely solely on having wash stations nearby such as at restaurants and commercial outlets. Many persons may carry small amounts of sanitizer with them. However, it may be inconvenient to locate wash stations, and reaching into one's pocket or pocket book to retrieve and use a portable bottle of sanitizer may promote the spread of viruses to personal items.
- The above information disclosed in this Background section is only for enhancement of understanding of the background of the inventive concept, and, therefore, it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.
- Exemplary embodiments provide a dispenser providing a convenient method for applying hand sanitizer.
- Exemplary embodiments also provide a wrist-worn dispenser providing a convenient method for applying hand sanitizer.
- Additional aspects will be set forth in the detailed description which follows, and, in part, will be apparent from the disclosure, or may be learned by practice of the inventive concept.
- According to an exemplary embodiment, a dispenser includes a reservoir having a first sheet and a second sheet connected at edges thereof, and a dispensing aperture arranged between the first sheet and the second sheet.
- According to an exemplary embodiment a dispenser includes a holster having a first ply and a second ply, a reservoir having a first sheet and a second sheet connected at edges thereof, and a dispensing aperture arranged between the first sheet and the second sheet, wherein the second ply forms a pocket on the first ply, and the reservoir is arranged in the pocket between the first ply and the second ply.
- According to an exemplary embodiment a clip includes a body having a tubular shape and a channel formed through the body and extending along an entire length thereof.
- The foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the claimed subject matter.

Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense, unless expressly so defined herein.
- An exemplary embodiment relates to a
dispenser 10, as shownFIG. 1 ,FIG. 8 ,FIG. 9 ,FIG. 10 andFIG. 11 . According to the present exemplary embodiment, thedispenser 10 includes aholster 1 to allow the dispenser to be wrist-worn, for dispensing sanitizer. Theholster 1 may be made of a synthetic or natural fabric or plastic sheet and secured to a user's wrist using abuckle 3 andhook 21 andloop 20 fastener. Avalve 2 extends from theholster 1 and may be directed towards the user's palm of hand. - The
holster 1 has abladder 4 arranged therein. Thebladder 4 is shown inFIG. 2 andFIG. 3 . The body of thebladder 4 is fabricated from two plies of sheet plastic such as polystyrene of polypropylene and is heat welded together at aseam 5. The bladder may also be fabricated using a blow mold technique. According to the present exemplary embodiment, thebladder 4 is a two-ply, heat welded six mil polypropylene material capable of containing fifteen cubic centimeters of hand sanitizer fluid of varying viscosity. Thebladder 4 provides a contained environment using a check valve-controlled, dispensing duct at one end thereof, and arefill opening 37 at the opposite end thereof. Thevalve 2 is secured to thebladder 4 using shrinkwrap tubing 8 compressed over the bladder plies, forcing them into a groove located on the valve body (described below with respect toFIGS. 5-7 b and 16 a-16 d). Thebladder 4 has aflap 6, and aclip 7 is slid over theflap 6 to secure and seal thebladder 4opening 37. -
FIG. 3 demonstrates how thebladder 4 is filled with fluid according to the present exemplary embodiment. Theclip 7 is removed from theflap 6 of thebladder 4. Theflap 6 is unfolded and separated to expose theopening 37. The sides of thebladder 4 are then squeezed using the thumb and index finger placed on the edges of thebladder 4 in order to expand thebladder 4. Sanitizer is then pumped into thebladder 4 to a level approximately two-thirds of the way up using a bottle withpump 9. Theflap 6 is closed by folding theflap 6 back on itself twice with each fold being approximately one quarter inch in width. Theclip 7 is then reinstalled by sliding it from one side and across the seam of thebladder 4. - The
clip 7, as shown inFIG. 4 , is made of a plastic material such as polyoxymethylene (acetal). Achannel 11 is cut in theclip 7 and notched 12 at both ends of theclip 7 to facilitate insertion onto theflap 6. A label embossed or stamped may carry brand, writing or technical information. According to further exemplary embodiments, theclip 7 may be used for restraining any multiple-ply sheet material such as tooth paste or cosmetic tubes to prevent the paste from moving away from the nozzle when being squeezed. - As shown in
FIG. 5 ,FIG. 6 ,FIG. 7a andFIG. 7b , thevalve 2 is a pressure valve having a body made of polyoxymethylene and that includes apolyoxymethylene ball 13 and aspring 17. Ball diameter and properly adjusted spring force is used to realize the optimal pressure required to release fluid to a user's hand. Thevalve 2 pressure release mechanism may alternatively be made of a cross-slotted diaphragm or other technique that would restrict the flow of sanitizer fluid until a critical pressure level is obtained. The spring constant and aperture (ball to seat dimension) permits a reasonable pressure be applied in order to release the sanitizer without the problem of unintended release, slow weep or discharge requiring excessive applied pressure. - A
cap 16, that contains a properly sized hole capable of retaining theball 13, is affixed to thevalve 2 body using a heat crimp 14 or cyanoacrylate adhesive. Thevalve 2 is adhered to thebladder 4 with the use ofgrooves valve 2 that permits the unification of thebladder 4 tovalve 2 using shrink tubing. This approach helps insure that no leakage takes place when pressure is exerted on thebladder 4, such as by using the fingers of an opposing hand. Avent 18 communicates fluid frombladder 4 to a user's palm. -
FIG. 7a andFIG. 7b are cross-sectional views of thevalve 2 as shown inFIGS. 5 and 6 according to the present exemplary embodiment. Avalve inlet chamber 16 a is provided between theball 13 and the valve chamber wall to allow fluid to pass when pressure is applied to thebladder 4 during operation, as shown inFIG. 7b . In conjunction with the size of theball 13, thespring 17 was chosen with a k value (i.e., force rate) commensurate with the desired pressure to release the sanitizer fluid. The length of thespring 17 along with the length of the spring chamber allows adjustment of the spring tension to fine tune the optimal pressure release point. According to the present exemplary embodiment, thespring 17 has a compressed length greater than spring chamber length, which is intended to prevent a situation where a solid height (i.e., all windings compressed upon each other) may be reached causing restriction or stoppage of the fluid through thevalve 2, such as by theball 13 blocking fluid from flowing through the spring chamber. -
Groove 15 a is used in concurrence with thecap 16 allowing the cap to be sealed to the valve body using a heat crimp.Groove 15 b performs two functions. First, it provides a pressure seal between thevalve 2 and bladder 4 (as described with respect toFIGS. 16a-16d below) and second, it prevents the valve from moving back into thebladder 4, such as if thevalve 2 is inadvertently forced backwards. -
FIG. 8 is a top view of theholster 1 showing thehook 21 andloop 20 fastener.FIG. 9 is a bottom view of theholster 1 having apocket 23 sewn thereon, thehook 21 affixed on a tapered end of theholster 1, and abuckle 3 affixed on the opposite end of theholster 1. Theholster 1 is secured to a user by threading theholster 1 through a “D” ring of thebuckle 3 and securing it with thehook 21 to theloop 20 sewn on the top side of theholster 1. - The
pocket 23 is accessed by afirst opening 22 about one-third of the way down thepocket 23, thefirst opening 22 perpendicularly orientated to thebuckle 3. Thepocket 23 also has asecond opening 24 along the bottom edge of theholster 1 for thevalve 2 to be exposed therethrough. Thebladder 4 is inserted into thepocket 23, and may be completely enclosed in thepocket 23.FIG. 10 is a view of the bottom side of theholster 1 with thebladder 4 overlaid on theholster 1 to show the area that thebladder 4 occupies in thepocket 23. - The method for dispensing hand sanitizer fluid onto the palm of a user's hand is shown in
FIG. 11 . According to the present exemplary embodiment, a user's hand, from the arm opposite of the arm having the wrist on which thedispenser 10 is attached, is placed over theholster 1 and pressed with a force that causes fluid 26 to expel from thevalve 2 and onto the user's palm. Thedispenser 10 may be attached on either wrist. - Approximately 0.5 cc of hand sanitizer in gel form may be required to fully coat one's hands. Given the number of times a user may encounter a situation where it would be advisable to cleanse one's hands during the day, the
bladder 4 having a 15 cc capacity provides, at a minimum, a one day supply. Also, thebladder 4 is easy to replace or refill in situ without the use of special tools. To accomplish this, thebladder 4 is configured as a separable unit from theholster 1. Individual bladders can be carried or stored for later use. - A
dispenser 100 according to an exemplary embodiment is shown inFIG. 12 andFIG. 13 . Thedispenser 100 may be substantially the same as thedispenser 10 described above with respect toFIGS. 1 through 11 of the present application, and the disclosure thereof is incorporated herein by reference, and any repeated disclosure may be omitted for the sake of brevity. Thedispenser 100 may be disposed after a single use, or when the reservoir therein is depleted. Abase ply 27 is made from low-cost felt, paper/fiber, or personal protective equipment (PPE) material. Abladder pack 28 is completely sealed after being filled, eliminating a refill capability (such as described above with respect to the bladder 4), and thebladder pack 28 is positioned on the top side of thebase ply 27. Asecond ply 29 used to enclose thebladder pack 28 and is affixed to the base ply 27 using weld or adhesive. Abuckle 31 is made of a low-cost material such as plastic or steel. Anattachment mechanism 30 may be hook and loop or a fastener similar to what is used on ACE™ bandages. -
FIG. 14 shows adispenser 200 according to an exemplary embodiment having a different method of attachment to a user than thedispenser 10 anddispenser 100. Thedispenser 200 may be substantially the same as thedispensers FIGS. 1 through 13 of the present application, and the disclosure thereof is incorporated herein by reference, and any repeated disclosure may be omitted for the sake of brevity. Anouter band 32 is made of a spandex-type material attached to the ends of apocket 33 made of non-stretchable fabric. A bladder pack 28 (orbladder 4, not shown), as described above, is arranged on thepocket 33. -
FIG. 15 shows thedispenser 200 with apocket cover 35 andexpandable retainer 36. Thebladder pack 28 is disposed in a pouch formed between thepocket 33 and thepocket cover 35. Theretainer 36 is connected to thepocket 33 and may be expanded or contracted to retain thebladder pack 28 in the pouch. Thedispenser 200 is reversible, whereby a pouch opening, for inserting and removing thebladder pack 28, may be arranged on the inside of thedispenser 200, closer to a user's wrist. -
FIG. 16a ,FIG. 16b ,FIG. 16c andFIG. 16d show a method for installing avalve 2 into abladder 4 according to an exemplary embodiment. The valve and bladder are substantially similar to the valve and bladder described above with respect to the exemplary embodiment shown inFIGS. 1-7 b, and the description thereof is incorporated herein by reference, and any repeated description thereof is omitted. Likewise, the description herein with respect toFIGS. 16a-16d is incorporated by reference in the exemplary embodiment shown with respect toFIGS. 1-7 b. The method according to the present exemplary embodiment assures an adequate seal betweenbladder 4 andvalve 2, thereby preventing leakage during use. - After the
bladder 4 is formed by a heat weld technique, a round tippeddowel 41 with a diameter of 0.230 inch is forced through achannel 40 in order pre-stretch the channel prior to insertion of thevalve 2, as shown inFIG. 16a . As shown inFIG. 16b , thevalve 2 is seated using asecond tool 42. The valve is in place when avalve cap 16 reaches the bottom of thebladder 4, as shown inFIG. 16c . A seal is made when shrinkwrap tubing 8 is applied over thegroove 15 b and heated with forced hot air, as shown inFIG. 16d . This way, the bladder tip material is pulled into thegroove 15 b and held in place by theshrink wrap tubing 8. - In an age where shaking hands may now socially unacceptable, the ability to cleanse one's hands prior to and after performing a hand shake may allow future acceptance of this tradition. In order to help achieve adoption of a wrist-worn hand sanitizer dispenser, the dispensers described above with respect to the exemplary embodiments are designed to be comfortable to wear and conform to the shape of a user's wrist, such that the dispenser fits under a dress shirt and allows free movement of the wrist.
- The dispensers according to the present exemplary embodiments provide a convenient method for applying hand sanitizer without the need for locating available wash stations at restaurants and commercial outlets or reaching into one's pocket or pocket book to retrieve and dispense a portable bottle of sanitizer. Retrieving a bottle of sanitizer could promote the spread of viruses onto personal items and clothing. In addition, it would not be convenient and not readily available for use wherever needed.
- Although certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Accordingly, the inventive concept is not limited to such embodiments, but rather to the broader scope of the presented claims and various obvious modifications and equivalent arrangement.
