DETAILED DESCRIPTION OF THE INVENTION

[0023] Referring now to the drawings in detail, FIG. 1 is a front perspective view of a free standing anti-pathogenic sink unit made in accordance with the present invention, where the sink unit is generally indicated by the numeral 10 with a sink 14 having a drain hole 18 at its bottom. Also included may be a soap or hand sanitizer dispenser 12. A faucet 16 dispenses water when pumped by foot pump 20. After the hand washing is finished, paper towels from paper towel dispenser 22 may be used for hand drying. In operation, someone will approach the sink unit, dispense soap and then begin hand washing. The resulting grey water can either be contained for sanitary disposal with indoor applications, or for outdoor applications, it may be released directly to the ground. For indoor applications, a rolling grey water tank may be removed from the sink unit and taken to a sanitary sewer access for proper discharge. Water from faucet 16 is pumped up and then used to rinse their hands and paper towels can be used to dry. In most aspects, a removable waste bin (not shown here, but shown in further aspects) is used to collect discarded paper towels after use.

[0024] FIG. 2 shows a two person sink unit, generally denoted by the numeral 30, with two first and second sinks 32 and 34 respectively. Paper towel dispensers 36 are mounted for ease of use on top of sink unit separator 42, the paper towel dispensers being located for easy access. Water filling channels 40 are easily accessed to replenish a fresh water tank contained therein (not shown here).

[0025] FIG. 3 is an exemplary barrier shield 50 designed to be fitted on sink unit separator 42 of FIG. 2. Such a virus barrier shield includes a screen 52 which may extend upwardly between the two sinks to provide physical distancing between the two people using the sinks. Virus barrier shield screen 52 not only acts as a biologic shield, it also acts as a back splash protector. Supports 54 may include at least one indent 56 for press fitting down onto the sink separator 42 of FIG. 2. This virus barrier shield may be transparent/translucent, or it may include an opaque quality look for visual separation or it may include a mirrored surface for grooming. I also envision that a soap dispenser or a hand sanitizer dispenser may be mounted on the virus barrier shield 52, as well as a paper towel dispenser.

[0026] FIG. 4 is a front perspective view of the free standing anti-pathogenic sink unit of FIG. 1 shown opened up for servicing. Sink unit 60 with sink drains 62. Soap pump orifice 64 includes feed tubes for dipping into a liquid soap reservoir, such that when soap is needed, pumping brings soap up to the surface. Waste water tank 66 receives the used grey water from the sink drains 62 after use. A stainless steel lid latch 68 is used to release the top of the sink unit 60. Foot pump 70 is used to bring water up through the faucet, shown in other aspects. An optional waste bin 72 may be suspended from the side of the unit to collect used paper towels. Water filling channel 74 is located above the fresh water reservoir for ease of refilling. At least one support strap 76 is attached to the lid to prevent unwanted motion of the lid. Drain lines 78 direct used grey water into wastewater tank 66.

[0027] FIG. 5 illustrates yet another aspect of the present invention, showing an assembled two person sanitation unit 80 in a closed position, with two dedicated sinks 82 in opposing positions. In this aspect, faucet 84 comes out of the sink separator. Soap dispenser 86 may alternatively dispense soap or 60% alcohol hand sanitizer liquid. Again, using foot pump 88 brings water from the freshwater reservoir inside the sink unit 80 for rinsing of hands after washing. Paper towel dispenser 90 provides fresh paper towels, and waste bin 92 may collect used towels. M As shown in FIG. 4, a lid latch 94 is used to unhook the lid from its base unit for servicing.

[0028] Looking lastly to FIG. 6, there is shown a multiple station sink unit, including a multiplicity of sink units 100. As can be seen from this figure, a barrier shield may prove useful attached to the separation 102 between the units, as well as being mounting under the paper towel dispensers. These sinks can be placed side to side for an unlimited number of dual hand wash stations.

[0029] While the units described hereinabove are preferably made of polyethylene, fiberglass, aluminum, wood or any other suitable material, a coating or impregnation of anti-pathogenic properties or fragrances in the manufacturing materials can be used to also build portable hand wash stations, laboratory buildings, comfort stations and hand sanitizers. Since this portable freestanding anti-pathogenic hand sanitation system may be used both inside and outdoors, such use of materials will provide resistance to outdoor elements.

[0030] In addition to having our outdoor element resistance, a number of materials may be added to the construction materials, including fragrances, antimicrobial materials, and/or ultra-violet stabilizers. Various additives may be incorporated into master batches of polymers prior to manufacturing. Among many other suppliers, such materials are commercially available from Wells Plastics Limited of the United Kingdom, and may include compositions such as Oxo—biodegradable technologies to accelerate the environmental degradation after use. Highly effective ranges of antimicrobial additive concentrates are commercially available as a variety of polymer carriers and powder dispersions.

[0031] In these times of COVID-19 virus threats, keeping everyone safe is of utmost importance, so use of hand washing in a safe environment is more important than ever. In that regard, suitable plastics or metal materials used in the fabrication of the present invention may include resins or polymers such as polyethylene, polypropylene, polyurea, polyurethane, or other suitable plastic materials. Depending on the desired application, hand sink may include, or may be coated with, any number of suitable anti-microbial materials, including such coatings such as Microban®, commercially available from Jon-Don Corporation of Chicago, Ill. Furthermore, a low concentration metallic silver component may be included or coated on my device for anti-microbial action in concentrations of from 0.001% percent by weight to 5% percent by weight of the total fabrication weight of material.

[0032] While other suitable anti-bacterial components may be utilized within or coated on the resin to accomplish this anti-microbial action, metal fabrication may be coated or plated with copper and its alloys, such as brasses, bronzes, copper, nickel, copper-nickel-zinc, and others; silver and silver containing alloys; zinc and zinc pyrion coatings on either plastic or metal; organosilanes; or other metallic antimicrobial materials. Silver compounds and silver ions may be incorporated into a polymeric construct material for the present hand sink to show antimicrobial properties. As a preferable aspect of the present invention, it has been shown that silver ions prevent DNA replication and affect the structure and permeability of the cell membrane. Silver also leads to UV inactivation of bacteria and viruses because silver ions are photoactive in the presence of UV-A and UV-C irradiation.

[0033] Antimicrobial polymers, also known as polymeric biocides, are a suitable class of polymers for the present invention with antimicrobial activity as they have the ability to inhibit the growth of microorganisms such as bacteria, fungi or protozoans. Antimicrobial agents in concentrations of from 0.001% percent by weight to 5% percent by weight of the total fabrication weight of material kill bacteria through different methods depending on the type of bacteria.

[0034] As untreated plastic articles can be attacked by microbic growth causing unsightly discoloration, unpleasant odors, and polymer degradation issues, antimicrobial additives can be incorporated within plastic resins during compounding or as a master batch during molding to provide a biocide treatment to control microbes. Bio-compatible technologies in concentrations of from 0.001% percent by weight to 5% percent by weight of the total fabrication weight of material may be employed to make plastics and/or polymers antimicrobial with an antibacterial performance of up to 99% within 24 hours, thereby killing germs within short order after contacting with contaminated surfaces. In yet another aspect, BioCote® is able to provide antimicrobial additives for plastics and polymers of all types, and is commercially available from BioCote, Ltd. of Oxfordshire, Great Britain.

[0036] The above examples include antimicrobial monomers which are included in a preferred aspect of the invention, and may be added into the plastic resin as a master batch formulation prior to molding. As noted, low concentrations of the antimicrobial monomers are effective, preferably included in an amount of from 1 mg to 3.9 mg per milliliter of resin.

[0037] Specifically, an additive such as Ultra-Fresh NM-100, which is commercially available from Thomson Research Associates of Toronto Ontario Canada, may be incorporated into the precursor polymeric material prior to form the sink unit. Ultra-Fresh NM-100 is a fine crystalline white powder used in the treatment of extruded and molded polymers to inhibit bacterial growth responsible for mal-odors, staining and product degradation. Ultra-Fresh NM-100, based on Triclosan as the active ingredient, can be incorporated into products in the manufacturing process by direct addition or through the use of a resin pellet concentrate (5%-10% Ultra-Fresh NM-100). This treatment, when used according to recommendations, will last the lifetime of the product.

[0038] In a further aspect of the present invention, antimicrobial coatings may be utilized incorporating aqueous solutions for anti-virus, anti-fungal, anti-bacterial, titanium dioxide compounds. Especially useful are nano-coatings that permanently bond to the surface of the hand sink so that neither bacteria, viruses, and fungi attach to the surface and grow. By “permanent” we mean that it will last the duration of the product or at least 3 years. Such an aqueous nano-coating is non-toxic and “kills” bacteria, fungi, and viruses on contact which is especially useful for this hand sink application which is a common breeding ground for gram negative organisms. Furthermore fragrance oils can be incorporated into the aqueous based antimicrobial coating.

[0039] It may also be desirable to incorporate fragrances into the master batches of the desired polymeric materials prior to manufacturing to offer manufacturers the ability to produce scented plastic goods that are attractive to consumers during their use. Such fragrances may enhance the experience of hand sanitation, and provide confidence to a user that the hand sanitation station is clean, and free from viruses. Although the present invention is preferably Rotocast, the unit may also be blow molded, injection molded, or be made of blown or thermal films.

[0040] The method of servicing and using the sink units includes the steps of preliminarily filling the fresh water reservoir with 1-2 gallons of water and gently rocking the hand wash station back and forth to flush out any scrap material. Then, one will tip the unit up, lie it on its end and drain water through the water fill hole. At this point the hand wash station is ready to fill with fresh water. After filling, one opens the top and places a waste container over the front lip of the unit. Liquid soap of any type is inserted into the soap reservoir by lifting top and filling the reservoir.

[0041] After the liquid soap is inserted, water is flowed into the sink through the water fill hole not to exceed capacity. An overflow mark and factory-drilled hole is located on the outside corner below the fill hole to indicate capacity.

[0042] Paper towels are inserted into the towel holder by lifting the towel holder lid, inserting towels and pulling the first towel out to get it started. Single, double, c-fold, or bi-fold towels may be used.

[0043] Methods for general maintenance for hose and foot pump are prescribed for care-free use. After each use, flushing out the system with any suitable disinfectant, preferably 1 oz. bleach to 3 gallons of water prevents calcium or lime build-up. Pump the foot pump until you smell bleach, and then store the unit away. Before next use, flush out with fresh water.

[0044] Seasonal maintenance requires further precautions. If storing in freezing conditions, empty all water and add some sort of anti-freeze, preferably 1 gallon of RV antifreeze. Pump both foot pumps until antifreeze comes out the faucets. Flush system with fresh water before next use.

[0045] In summary, numerous benefits have been described which result from employing any or all of the concepts and the features of the various specific aspects of the present invention, or those that are within the scope of the invention. The free standing anti-pathogenic hand sanitation station described above acts to reduce spread of viruses and disease for users.

[0046] The foregoing description of various preferred aspects of the invention have been presented for purposes of illustration and description. It is not intended to be to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings with regards to the specific aspects. The aspects were chosen and described in order to best illustrate the principles of the invention and its practical applications to thereby enable one of ordinary skill in the art to best utilize the invention in various aspects and with various modifications as are suited to the particular use contemplated.
