The present invention generally pertains to a method and a device for storing and dispensing an antimicrobial solution, and more particularly, to a method and a device for storing and dispensing a silane quaternary ammonium ion or salt thereof.
According to one aspect of the present invention, a method is provided for storing and dispensing an antimicrobial solution comprising: providing a bag-on-valve can; and filling the bag-on-valve can with the antimicrobial solution, the antimicrobial solution comprising a silane quaternary ammonium ion or salt thereof.
According to one aspect of the present invention, a bag-on-valve can is provided for storing and dispensing an antimicrobial solution. The bag-on-valve can comprises: a can having an opening; a valve sealed in the opening of the can; a bag attached to the valve and provided in the can, wherein the bag is filled with the antimicrobial solution, the antimicrobial solution comprising a silane quaternary ammonium ion or salt thereof; and an actuator for actuating the valve in order to dispense the antimicrobial solution.
According to one aspect of the present invention, a method of storing and dispensing an antimicrobial solution comprises: providing a bag-on-valve can; and filling the bag-on-valve can with the antimicrobial solution, the antimicrobial solution comprising a silane quaternary ammonium ion or salt thereof, wherein the silane quaternary ammonium ion or salt thereof is one or more of:
These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.
In the drawings:
The present illustrated embodiments reside primarily in combinations of method steps and apparatus components related to a bag-on-valve can. Accordingly, the apparatus components and method steps have been represented, where appropriate, by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein. Further, like numerals in the description and drawings represent like elements.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in
The terms “including,” “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element preceded by “comprises a . . . ” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
The bag 2 may be a laminated aluminum bag, or may be made of polyethylene terephthalate (PET), polypropylene (PP), or polyethylene (PE). The can 6 may be made of aluminum or tin plate. The propellant 4 may be compressed air or nitrogen. The propellant 4 may have a pressure of 30-80 psi.
The antimicrobial solution 3 comprises a silane quaternary ammonium ion or salt thereof. The silane quaternary ammonium ion or salt thereof may be one or more of:
The solution includes a liquid component that carries the silane quaternary ammonium ion or salt to the surface to be treated, allowing the silane quaternary ammonium ion or salt to bond to the treated surface. The liquid component dries off leaving the silane quaternary ammonium ion or salt to be bonded to the treated surface. The silane quaternary ammonium ion or salt thereof is not necessarily known for quick-acting microbial reduction like a disinfectant. However, the silane quaternary ammonium ion or salt thereof provides residual long-lasting antimicrobial activity that is not consumed while destroying the virus or other microbe. The silane quaternary ammonium ion or salt thereof may be between 0.1 percent and 10 percent by weight of the solution.
The antimicrobial solution may further comprise water as the liquid component. The solution may further comprise isopropyl alcohol as the liquid component (solvent). In embodiments, the isopropyl alcohol is between 30 percent to 90 percent by weight of the solution. The solution may include both water and isopropyl alcohol. An example solution comprises (by weight) 60.0 percent isopropyl alcohol, 2.02 percent 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, and 34.19 percent deionized water.
The antimicrobial solution may further comprise hydrogen peroxide. The hydrogen peroxide may be 0.05 percent by weight to 7.5 percent by weight of the solution. The hydrogen peroxide operates as a disinfectant, which compliments the long-lasting antimicrobial properties of the silane quaternary ammonium ion or salt.
The antimicrobial solution may further comprise hypochlorous acid. The solution may further comprise hypochlorous acid, a silane quaternary ammonium ion or salt thereof, and water. The hypochlorous acid may exist in the solution at a concentration of 0.1 to 1000 ppm. The hypochlorous acid may exist in the solution at a concentration of 0.1 to 200 ppm. The hypochlorous acid may exist in the solution at a concentration of 200 to 1000 ppm. The hypochlorous acid operates as a disinfectant, which compliments the long-lasting antimicrobial properties of the silane quaternary ammonium ion or salt.
Referring now to
As shown in
Next, in step 28, the bag 2 is filled with the antimicrobial solution 3 through the valve 1. This step is illustrated in
It is to be understood that variations and modifications can be made on the aforementioned structure without departing from the concepts of the present invention, and further it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
This application claims priority to and the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application No. 62/706,277, filed on Aug. 7, 2020, entitled “METHOD AND DEVICE FOR STORING AND DISPENSING AN ANTIMICROBIAL SOLUTION,” by Patrick E. Eddy, the entire disclosure of which is incorporated herein by reference.
