Abstract:
The invention provides for a shaving device for increased hygiene in the shaving process. During the shaving process organic material in the form of the minute bits of dead skin and cut pieces of hair get lodged in the shaving head. This organic material forms a breeding ground for bacteria and fungi. The invention consists of coating the shaving device with oily liquid containing a chemical sanitizer which works as anti microbial agent and keeps the shaving device free from germs and thus protect the shaver from infections'.
Full Specification:
The following specifications particularly describe the nature of this invention and the description thereof.
Title of the Invention:
"Self Sanitising Shaving Device"
Technical Field:
This invention relates to shaving devises and more particularly to antimicrobial treatment of shaving devices.
Definition:
The words "Shaving Device" appearing hereinafter mean any kind of shaving device or shaving system containing a razor or a blade or a razor blade or a shaving cartridge or a disposable shaving razor of any description or any device used for the purpose of removing, cutting or shaving hair on human body.
The words "Shaving Head" appearing hereinafter mean any kind of device or cartridge consisting of a plastic body containing a single or multiple sharp blade edges used for the purpose of removing, cutting or shaving hair on human body.
Background of the Invention
The razor blade industry in the 1970s has seen the emergence of the razor in the form of a handle and a plastic device with embedded shaving blade edge on its side which is known as the "Disposable Razor". Thereafter about 2 decades ago, a leading manufacturer of blades

introduced a razor with twin blade shaving head, which for the first time had 2 shaving edges on the same side of the shaving device. Both the blades were held together in the plastic body and shaved in tandem at the same time. The market readily accepted the product and soon most of the leading manufacturers came to the market with similar products. Thereafter there was a race in developing shaving heads with multiple shaving edges. Now there are shaving devices with 3, 4, 5 and even 6 blade edges on the shaving head.
The complex structure of the shaving head has increased the difficulty in cleaning its inner nooks and corners. In the process of shaving, organic material in the form of bits of dead skin and pieces of cut hair get lodged in the difficult-to-clean-places in the shaving head of the shaving device. This organic material is good food for bacteria. Therefore bacteria thrive on the shaving debris which accumulates in the hidden recesses and difficult-to-clean places in the structure of the shaving head.
The possibility of infection to the shaver due to bacterial growth in the shaving head cannot therefore be ruled out The inventor found a treatment to the shaving device to negate the bacterial growth and thereby stem the cause of any possible infection in this invention. The inventor invented the idea of having a sanitising chemical coating on the razor to effectively quell the bacteria and keep the razor free of any infection.
The present invention describes the application of sanitising agent in suitable medium to keep the shaving device free of bacteria.
Description of the Product in the Invention
The invention provides for the design of the "Self Sanitizing Shaving Device" with the description of the distinguished features of the Product
The Rationale behind the Invention:
Hand Sanitising has become a necessity in today's infective environment. Yet no attention is being paid to the hygiene of the shaving instrument Manufacturers vie each other to produce complex shaving heads containing multiple blades and claim that the same shaving head could go on shaving for one month or even longer! During the period, bacteria have the opportunity to multiply millions of times on the organic debris of dead skin cells and cut hair pieces lodged in the recessed parts of the

razor! It is therefore logical to think that the sanitising chemicals could be used in disinfecting the razor. A simple solution to the problem could be to use a disinfecting solution and dip the razor head in it after and or before shave. But this is not always possible in today's rush-rush lifestyle. It was this health hazard which needed to be mitigated. The inventor in the present invention provides for a disinfecting chemical applied on the surface of the shaving device to quell and inhibit bacterial growth. The disinfectant is applied through a medium of hydoophobic liquid or oil which will not be washed away by thesoapy foam and in the process of rinsing the shaving device after the shave.
Silicone oil which does not wash away with rinsing, provides a coating liquid medium which is hydrophobic and which does not support any bacterial or fungal growth. Application of Silicon oil itself is an antibacterial treatment Addition of sanitizing chemical makes the silicone oil even more effective. A microbial assay was made of shaving device after shaving for 6 days. The assay showed 36 bacterial colony forming units (cfu) present on the said shaving device. The same microbial assay was conducted under exactly similar conditions of shaving for 6 days with the shaving device which was treated with silicone oil containing 0.2% Triclosan. The result of the assay showed only 10 bacterial colony forming units (cfu)! The test brought out the effectiveness of the anti-microbe treatment given to the shaving device.
Process of making the Product in this invention:
The disinfecting liquid is made by dissolving a sanitising agent such as Triclosan in a suitable solvent like acetone or isopropyl alcohol. This solution is then mixed with silicone oil in such proportion as to have the final liquid containing the desired concentration of Triclosan. The resultant solution hereinafter called "sanitising silicone oil" is then sprayed on the plastic parts of the shaving device before assembly with the blades edges or the resultant sanitising solution is sprayed on to the finished shaving heads or disposable shaving razors by process known in the art. Thereby each shaving head or each disposable shaving razor with its handle will have a thin layer of the sanitising silicone oil on its surface.
Distinguished feature of the invented Product
The product under this invention is distinguished from prior art by the fact that on the surface of the shaving device there is a thin layer of

silicone oil with a non-alcoholic anti bacterial agent in concentrations of not less than 0.02 % w/w and not more than 0.8 % w/w.
The product under this invention is distinguished from prior art by the fact that scrapings from the surface of the plastic body of the shaving device will show traces of one or more of the following chemicals:
1. Triclosan
2. Povidone-iodine
3. Benzalkonium Chloride
4. Benzethonium Chloride
5. Triclocarbon
6. Silicone Oil
Prior Art:
There are no shaving devices or shaving systems containing any razors or blades or razor blades or shaving cartridges or disposable shaving razors of any description in prior art which claim to have anti-microbe, or anti-bacterial or anti-fiingal properties.
In prior art, there are no shaving devices or shaving systems containing any razors or blades or razor blades or shaving cartridges or disposable shaving razors of any description which claim to have a coating of antimicrobial liquid or sanitizing substance on their surface.
There is no shaving device or shaving system containing any razor or blade or razor blade or shaving cartridge or disposable shaving razor of any description which claims to suppress or inhibit bacterial growth in prior art.
Innovation in the Invention:
1. The invention consists coating the shaving device with oily liquid containing a chemical sanitizer which works as anti microbial agent and keeps the shaving device free from germs and thus protect the shaver from infections.
2. The invention creates a shaving device which will clean itself of any bacterial or fungal infection which may occur during shaving process.
3. The invention creates a shaving device which will inhibit or prevent the bacterial and fungal growth from occurring on the minute pieces of skin and hair lodged in the recesses of the razor or its handle during the daily or periodic interval between shaves.

4. The invention creates a more hygienic shaving device.
5. The invention creates a product for more hygienic shaving process.
6. The invention creates a shaving device with a layer of sanitising liquid on its surface.
7. On the first shave the new shaving head is clean of any microbial presence. But during the shave, minute particles of dead cells of the skin and pieces of hair material get lodged in the nooks and corners of the shaving head.This organic material invites microbial growth during the 24 hours that elapse between shaves.
In the present invention, the bacterial growth is killed and the razor is disinfected with the sanitizing liquid layer on the surface of the razor. Thereby the invention does not allow the bacterial infection to proliferate day after day, shave after shave. A self-disinfecting razor which disinfects itself from the effects of the shaving process is new invention and not known in prior art.
