Arch-cap / soda cap

Arch-cap

When people purchase or carry carbonated beverage, they have no judgement of the inside pressure and it possibly causes liquid splash due to temperature increase or bottle sloshing.
This design helps make the right judgement of opening bottle caps by means of cap deformation.The top of caps stays sunken under normal pressure. Inside pressure increases when carbon dioxide is being decomposed.Then the bulge of the top follows.It is recommended to open the bottle when the top becomes sunken.
