<p>The present invention relates to a paper cup and a paper cap which comprises a top plate and a side wall that is installed downward around the edge of the top plate, wherein the side wall is reinforced with reinforcing materials. The paper cup can be tightly covered with the cap by preventing the cap from being damaged through the reinforcing materials. Therefore, the cap is not easily separated from the cup. Furthermore, the invention provides a paper cup having a housing portion formed between the top plate and the upper end of the inner side of the reinforcing material. Since the housing portion houses and holds the rim of the upper end of the cup, firm coupling between the cap and the cup is enabled. Therefore, the paper cap is not easily separated from the cup and enables the prevention of overflow of drinks in the cup even if the cup is shaken.</p> |
