Today’s invention attempts to deal, again, with the problem of people who refuse to wash their hands on exiting the bathroom.
It takes the form of a circular door handle (orange). This would be made from bacteria-inhibiting plastic.
The handle would be located in a cylindrical housing as shown. Each time the door hinge was moved, the circular handle would rotate within the housing, driven by the three wheels indicated.
A fresh segment of handle would therefore be presented to each new door user.
The housing might also be equipped with additional cleaners, such as a disinfectant spray and air dryer or even a small microwave (in the red box).
