Don't Kiss the P.E.T / plastic bottle

Mostly, people drink water out of PET bottles with their mouths being in contact with
those of bottles, when bacteria and germs propagate in the bottles. If by any chance
they reuse the bottles, the beverage inside is contaminated as much as river water.
Moreover, when they happen to share the beverage with others, they cannot but feel disgusted.
This design takes a novel and deliberate approach to keep your mouth from touching the bottle.
Upon opening the PET bottle, you will see a widget pop up like a prohibition sign that arouses
your attention and keeps a safe distance between your lips and the mouth of the bottle
