When drinking beers from a bottle or tin or glass you are likely to spill it over your clothes, your face and your friends, especially in traveling or party circumstances.
In order to avoid it a special brand or bottles and tins should be constructed, that would deliver the drink directly to one's mouth. That could be some nipple or a cocktail tube, but that's infantile and banal. My progressive idea is designing a special kind of bottle lid (or tin opening) that would spray drinks precisely to your throat in a spurt, just like a deodorant spray.
It would be very extravagant way to drink beers this way, would it not?
