Paper cap

Abstract

Disclosed is a paper cap. The paper cap includes a top plate, and a sidewall formed downward at an edge of the top plate, and the sidewall is reinforced with a reinforcing member to firmly attach the cap to a cup, thereby preventing the side wall from trembling and thus preventing the cap from being easily taken off from the cup. Further, a receipt part is formed between an inner top of the reinforcing member and the top plate. The receipt part grasps the circumference of the top end of the cup and thus strengthens the connection between the cap and the cup, thereby not only preventing the cap from being taken off from the cup but also preventing a beverage in the cup from overflowing even if the cup is shaken.
