Easy-Open / Easy-open bottle cap

No bottle opener when can still easily open bottle caps.
When the opener is not around, it is difficult to open bottles of beer and carbonated drinks.
"Easy open" use "tearing" of the way, you can easily tear the metal cover, when the opener is not around to protect your hands and teeth.
Tear along the dotted line the middle of the metal bottle cap and then the upper part of the cap will fall off naturally, even without the metal cap opener is also easy to open.
