We often drink carbonated beverages which bring us refreshing taste because of their abundant carbon dioxide. Although the carbonated drinks are so delicious, they often cause us trouble. When the carbon dioxide dissolved in drinks and separated from water, the excess carbon dioxide must be packed in a limited space. At this time, when we open it, the drink will splash out, causing distress to us. The design is applied for noticing splashing by using a pit at ring pull place, which shows the pressure in the can, thus gives a warning of bursting out. It functions like this: the designing place will sunken down when the carbon dioxide dissolved in water molecules, on the other hand, it will protrude, so we can easily know what is the proper time to enjoy the tasteful and refreshing drinks.
