The present invention relates to the field of sanitizing device. Particularly, the present invention relates to the field of sanitizing of commonly used object by public especially to prevent spread of contagious diseases. More particularly the present invention provides a disinfectant apparatus for sanitizing of paper currency.

BACKGROUND OF THE INVENTION
Contagious diseases are the diseases which can easily spread among people and affects the structure or function of all or part of human beings. The transmission of contagious diseases can happen through various means such as air, contaminated water and common objects etc. In such case, paper currency is one of the common objects that is regularly used by people. Even though digital payment method is available nowadays, but still in many areas such as small business industries, shops and grocery stores etc., uses paper currency.

The paper currency is the most potential object of carrying contagious diseases. Therefore, increased risk of transmission of disease may happen during currency exchange through hands among unknown individuals. Due to such activity contamination at places such as banks, shops, grocery stores are more prone to spread of contagious diseases. The sanitization of paper currency is of utmost importance such that the deadly virus or bacteria causing contagious disease shall be eliminated during exchange. The sanitization of individual paper currency may not be possible at each time of exchange. A device is required which can sanitize the paper currency during exchange and keeping currency intact.

There are certain existing inventions proposing innovative solutions which may resolve the above said issues. The existing inventions proposed to resolve different aspects of the problems are mentioned below. For example, Patent application US2015335775 describes a sanitizing machine comprising a supporting structure which includes two compartments or chambers (A, B), wherein, when the machine is in stand-by, a first compartment (A) is open and is able to house at least one container or object to sanitize, while a second compartment (B) of the machine houses a sliding door, which hermetically and automatically closes the first compartment (A) when the machine is on. The method thereof provides for at least one type of sanitizing cycle, such as an ozone cycle, a sanitizing liquid cycle and a combined cycle. The invention provides a sanitizing machine but may not be suitable for sanitizing currency.

Patent application CN200942194 describes a disinfection mechanism for currency count machine, which comprises a currency count machine assembly, a liquid conveyance pump, a liquid storage tank and a liquid conveyance tube.
