Anti-overflow / cup lid for take-out


General cold drinks that use flat lid could be spilled out of cups from the middle of straw inserting opening of the lid when the drinks are shaken. These drinks would be spilled out on hands or clothes to result to consumers’ inconvenience and more seriously to distract driver’s concentration to cause serious driving accident. The section of Anti-overflowing lid is shaped as two half-dome to solve the problem of drinks overflowing. When a drink cup with Anti-overflowing lid is shaken, some liquid rising up to touch this special lid would be offset its strength and finally the half-dome-shaped lid will guide back these liquid to the cups.
