ANTI-MICROBIAL FOAM DISPENSING SYSTEM
A portable system for delivering an anti-microbial foam includes a product dispenser for providing an anti-microbial solution. The product dispenser includes a rigid canister that contains the anti-microbial solution and a propellant and a nozzle assembly that includes a flexible actuator toggle nozzle. The product dispenser delivers the anti-microbial solution from the dispenser as a foam. The product dispenser may be assembled with a canister holder that can be attached to an object such as a person's waist belt or clothing. Alternatively, the product dispenser may be assembled with a lanyard to be worn about a person's neck.
The present invention relates to a system for delivering an anti-microbial foam.
BACKGROUND OF THE INVENTIONMicrobiological pathogens on the hands may be transferred to other body parts such as the mouth, nose and eyes are a primary cause of infectious diseases. Of course pathogens may also be transmitted from the hands of one person to another person and to/from inanimate objects (such as door knobs) to persons. Accordingly, hand antisepsis before and after contact with other persons or dirty objects is crucial to the prevention and transfer of control of microbiological pathogens. Hand hygiene can be improved by using various hand sanitizing fluids. The devices known in the prior art for providing a disinfecting product to the hands of a person may be overly complicated, making them costly. Some of the devices require a person to squeeze or put pressure on the device, which may be difficult for some persons such as those with arthritis.
DISCUSSION OF THE PRIOR ARTU.S. Pat. No. 5,683,012 discloses a dispenser for dispensing an alcohol-glycerine disinfecting gel or liquid. The dispenser has a main housing that mounts a pumping mechanism for pumping out the disinfecting gel from a replaceable, disposable supply cartridge releasably mounted in the main housing. The main housing is small enough to fit into in a person's hand, and the person may dispense the contents by simply squeezing the two parts together. The gel may be applied directly to the same hand that has squeezed the main housing. The dispenser may be worn by the person, such as on a waist belt. However, the device of the present invention does not include a pumping mechanism.
U.S. Pat. No. 5,927,548 is a continuation in part of U.S. Pat. No. 5,683,012 and requires a particular configuration of a dispenser with respect to a device for securing the dispenser to a person. Again the device has a pumping mechanism and the present invention does not include a pumping mechanism.
U.S. Pat. No. 7,617,952 B2 discloses a dispenser for a disinfecting gel. A container of disinfecting gel is attached to a device that is used to squeeze the container and cause the gel to be dispensed from the container. The device is provided with a means of attaching the device to a person's clothing. The present invention does not require a person to squeeze a container.
U.S. Pat. No. 7,988,020 B2 discloses a wearable fluid dispenser including a reusable holster and a disposable cartridge containing fluid, wherein the cartridge is made of a material having a flexibility higher than the flexibility of the holster, and wherein applying pressure to the cartridge allows dispensing onto the palm of the user's hand by way of increased pressure within the bottle causing the silicone valve to open and gel dispensing downwards. It is believed that a disadvantage of this device is that there is a very high probability that the use of the device will facilitate the transfer of microbes to the users clothing because of the mode of operation requiring a user to reach between his clothing and the device to squeeze the device to dispense the product. The present invention does not require a person to squeeze a container.
SUMMARY OF THE INVENTIONThere is provided in accordance with the present invention a portable system for delivering an anti-microbial foam. The system includes a product dispenser for providing an anti-microbial solution comprising: (a) a rigid canister that contains the anti-microbial solution and a propellant; and (b) a nozzle assembly that includes a flexible actuator toggle nozzle, the anti-microbial solution being delivered from the dispenser as a foam. The product dispenser may be assembled with a canister holder having a means for attaching the canister holder to an object such as a person's waist belt or clothing. Alternatively, the product dispenser may be assembled with a lanyard to be worn about a person's neck.

The mounting cup 27 is a closure fixed to a second end of the rigid canister 11 with a mounting cup gasket 28 providing a seal between the mounting cup and the canister 11. A stem 21 controls the flow of anti-microbial solution 17 from the canister. A stem gasket 24 extends circumferentially around the stem and is the “on-off” switch of the dispenser. A dip tube 18 extends from the stem with an open end 19 of the dip tube located in the liquid comprising a mixture of anti-microbial solution and propellant. A housing 22 encloses the stem 26, and a spring 23. The housing butts up against the stem gasket 24. The spring 23 urges the valve in a normally closed configuration. Pressure exerted on an actuator 26 via movement of the flexible actuator toggle nozzle 13 of the nozzle assembly 12 by a user moves the stem 21. This breaks the seal between the stem gasket 24 and the stem 21. The stem is thereby exposed to the anti-microbial solution and the propellant in the container, that is to say the valve is open. Pressure inside the container pushes the anti-microbial solution through the valve to the exterior of the canister and into the lumen of the flexible actuator toggle nozzle 13. The narrow nozzle serves to atomize the flowing anti-microbial solution which in the present invention is presented to the user of the device as a foam. That is to say an anti-microbial solution employed in the practice of the present invention is preferably a foaming anti-microbial solution. As used herein and in the claims the term “foam” is understood to have its common meaning of “a mass of small bubbles formed in or on a liquid”. Releasing the actuator, by a user releasing force on the flexible actuator toggle nozzle 13, allows the spring 23 to urge the stem orifice to the sealed configuration, that is to say the valve is closed. The device of the present invention allows a user to experience an advantageous two finger operation of the dispenser, which in itself negates the systems' components from being bacteria carriers. As used herein and in the claims the term “product dispenser” is understood to refer to the assembly of a rigid canister containing an anti-microbial solution under pressure and a nozzle assembly that includes a flexible actuator toggle nozzle.
