Gear Cap / Beer cap

Gear Cap

It's hard to open a beer bottle without a opener.And pop-top beer cap has a bad influnce on beer's taste.
We redesign the cap by rebuilding the side of it to shape the cap as a gear wheel. A couple of bottles can gear into each other easily.Prise the bottle ,the cap will be opened.This design is brief and convenient.Also,it can encourages people chat with each other.
