The wonderful moment you are to enjoy soda, watch out if you have violently shaken the bottle, for liquid filled with gas would spout upon you twist the cap. The brand-new type of soda bottle cap will have the problem solved. With double layers of vents, this device is able to expel the gas insides when to be opened. Usually the two layers of vents are staggered so that soda would be adequately sealed. When the cap is twisted 30 degrees, the internal structure would be right in place, the vents would coincide and the whole device starts to deflate air within the bottle. In the further twist, two caps are driven to be opened. Now enjoy soda!
