, Description:Field of Invention:
The invention relates to a sanitary napkin dispenser. More particularly, the invention relates to a sanitary napkin dispenser, which is capable of informing concerned authorities if the dispenser is vacant.

Background of the Invention:
According to research 23 million girls drop out of school annually in India, due to lack of proper menstrual hygiene management facilities, which include availability of sanitary napkins. Further, 121 million girls and women are currently using an average of eight non-compostable sanitary pads a month. The menstrual waste generated in India is estimated to be 113,000 tonnes annually (The Menstrual Health Alliance India, 2017). During the first three days of menstruation they need to change their sanitary napkins every three to four hours else they will be easily getting affected by uterus Cancer and Toxic Shock Syndrome (TSS) and Reproductive Tract Infection (RTI). TSS can affect anyone who uses the tampons for long time. Accordingly, there arises a need to develop sanitary napkins delivery system, So there is a need to make the sanitary napkins easily available to them, which can be achieved by vending machines. Napkin Vending Machine is a personal hygiene product for women. It allows immediate access to napkins anytime of the day to meet menstrual emergencies. It also saves women from embarrassment faced while buying napkins at the shop. By installing vending machines in the living areas, working area and educational institutions, it would help them to get the napkins as and when required added to it we have extended our work to make it a live machine where the sensors monitors the number of pads count and immediately send the message to the authority for immediate refilling so this makes the system operative. The machine works with DC (with the help of solar panel) and AC supply (during power drop Viz. DC supply).
US6799695 discloses a sanitary napkin dispenser device which includes a hinged lid allowing ready placement of the sanitary napkins within the device housing. When closed, a latch secures the lid. On one or more sides of the housing, a door is provided near the bottom that allows the user to retrieve a sanitary napkin from the bottom of the housing. The door or doors are hinged with a spring providing a bias to the closed position. Attached to the lid is a spring, the spring having an attached compression plate. When the lid is closed, the spring forces the compression plate against the sanitary napkins within the housing, thus maintaining the sanitary napkins in the proper position and orientation for grasping by the user, through the door. Hooks are provided to support a disposal bag.
However, there is none of the device which actually notifies the authorities when the sanitary napkin dispenser is vacant.

Detailed description of invention:
The invention relates to a sanitary napkin dispenser, which notifies authorities when the dispenser is vacant.
Women hygiene is of utmost importance and is to be taken care of. Women in India are still shy of buying napkins from medical shops and other stores. A solution to this problem is installing napkin dispensing system in schools, colleges and public places.
A sanitary napkin dispenser which functions when a coin is dropped into the dispenser, said dispenser comprises of anIR sensor for detecting dropping of coin into the dispenser. A power source could be a battery or solar power source. The power source can also be an AC electric power source. A motor moves a spring coil which allows the sanitary napkin for passing the sanitary napkin out from the dispenser. The spring coil is rotated by the motor when a relay switches on the motor. A microcontroller directs the movement of the motor to dispense the sanitary napkin. The microcontroller keeps track of the available napkins in the machineand if the count gets lowered the IR sensor activates the GSM module and sends signal via SMS to the authority for refilling the napkins.
An electronic device gets messages from the microcontroller.
The napkin dispenser is designed to work with coins. The coin sensor is to differentiate the coins in the coin acceptor panel; the spring mechanism is used here. IR sensor is used to count the number of napkins in the dispenser. When a coin is dropped, the micro controller sends signal to turn ON the relay resulting in switching on the motor, which rotates the coil to dispense the tissue pads. On the other hand the Microcontroller keeps track of the available napkins in the machine and sends message to the authority if the number gets reduced than the fixed value. The proposed model uses both AC and DC supply. For the DC supply power form solar is extracted through solar panel.
Figure 1 shows a flow chart showing that how the information is transferred from one component to the other.
The information from power source which supplies power to the microcontroller and other components such as motor, relay and spring coil. The IR sensor sends information to the microcontroller, which sends information to the electronic device.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
