In some other preferred embodiments of the present invention, the at least one antibacterial component is selected from the group consisting of a non-necrotic fatty acid compound, a bis-biquanido hexane, a quaternary ammonium salt, an N-tetradecyl pyridium salt and an N-tetradecyl ethyl pyridium salt and combinations thereof. In other preferred embodiments of the present invention, the flavoring additive is selected from the group consisting of oil of peppermint, oil of spearmint, oil of clove, oil of wintergreen, oil of cinnamon and combinations thereof. In other preferred embodiments of the present invention, the flavoring additive is selected from the group consisting of oil of lemon, oil of almond, oil of nutmeg, oil of orange, oil of anise and combinations thereof. In yet other preferred embodiments of the present invention, the flavoring additive is selected from the group consisting of oil of savory, oil of celery, oil of rosemary, oil of thyme, vanilla and combinations thereof.
In some embodiments of the present invention, the flavoring additive may be selected from the group consisting of lime, banana, cherry, brandy, rum and combinations thereof.
In some embodiments of the present invention, the flavoring additive may be selected from the group consisting of butterscotch, imitation brandy, synthetic vanilla, synthetic flavor and combinations thereof.
In some preferred embodiments of the present invention, there is about 10% to about 25% of the antibacterial agent.
In some preferred embodiments of the present invention, there is about 0.02% to about 4% by weight of the flavoring additive.
The present invention is also directed to a methodology for sanitizing a toothbrush, which includes: (A.) providing a hand-held portable spray container, the spray container containing a solution comprising: (a) water; (b) a flavoring additive; and, (c) about 0.5% to about 30% by weight of at least one antibacterial component. (B.) spraying a toothbrush with an effective amount of the solution from the spray container. The particulars are the same as set forth above in the preceding paragraphs of this Summary section.
Additional features, advantages, and embodiments of the invention may be set forth or apparent from consideration of the following detailed description, drawings, and claims. Moreover, it is to be understood that both the foregoing summary of the invention and the following detailed description are exemplary and intended to provide further explanation without limiting the scope of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate preferred embodiments of the invention and together with the detail description serve to explain the principles of the invention. In the drawings:
The present invention methodology involves sanitizing toothbrushes before use. Toothbrushes are considered by many dentists and other professionals to be a major cause of oral diseases and infections, due to their covert function as carriers and delivery systems of microbes and other bacteria that initiate these diseases and infections. Some proposed solutions to these problems include disposing of brushes frequently, utilizing antibacterial mouthwashes or even coating toothbrushes during manufacture to reduce anaerobic and bacterial activity.
While each of these proposals may be helpful, none deal with the immediacy of significant exposure to random carriers, such as large (non-nueroscopic) pieces of enemy-carrying debris, and some prior art methods are very risky, such as reliance upon toothbrush replacement.
The present invention solves these prior art problems by providing a portable, hand-held spray container for applying an effective amount of a sanitizing solution to a toothbrush anywhere, anytime, and especially immediately prior to each use of a toothbrush. This methodology is particularly beneficial for travelers and other situations where their brushes are not necessarily maintained in a clean environment.
The solutions are aqueous solutions, i.e. water or distilled water-based, and include a flavor additive and at least one active component, i.e., at least one antibacterial component. The antibacterial component is included in an amount of about 0.5% to about 30% by weight of the solution and preferably about 10% to about 25%. The flavor additive may be in any amount, understanding that the flavor additive is preferably strong enough to be a consumption deterrent. In other words, to discourage users from ingesting the solution. The preferred range of flavor additives is about 0.02% to about 4% by weight.
The balance of the solution is water. By “water” is meant H2O and any other inert constituents with water that would not have any effect on the active component(s).
The methodology is shown in
The pyridinium salt used in the present invention is either an N-tetradecylpyridinium salt or an N-tetradecyl-4-ethylpyridnium salt. These salts are known in the art as seen by U.S. Pat. No. 2,446,792, Aug. 10, 1948 to Shelton et al and U.S. Pat. No. 2,295,504, Sep. 8, 1942 to Shelton, both incorporated herein by reference. The N-tetradecylpyridinium salt can be represented as follows:
C-14-(pyridinium)+X−
wherein X− is an acid ion constituent such as fluoride chloride, bromide, iodide, nitrate, acetate, phenylsulfonate among many others. The preferred ions are the fluoride, chloride, bromide and iodide with chloride being the most preferred.
The tetradecylpyridinium salt has the ethyl group at the “4” position on the ring and can be represented similarly:
C-14-(ethyl pyridinium)+X−
wherein X− is defined above.
The flavorant can be a flavoring oil, and preferred are oil of peppermint, oil of spearmint, oil of clove, oil of lemon, oil of almond, oil of nutmeg, oil of orange, oil of wintergreen, oil of anise, oil of savory, oil of cinnamon, oil of celery, oil of rosemary and oil of thyme (the above are ethanol flavoring extracts). Other flavorants include vanilla, lime, banana, cherry, brandy, rum, butterscotch, imitation brandy and synthetic vanilla. Artificial and natural flavorants can be used.
Although particular embodiments of the invention have been described in detail herein with reference to the accompanying drawings, it is to be understood that the invention is not limited to those particular embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope or spirit of the invention as defined in the appended claims.
