PURPOSE: A paper cup with self-cover is provided to replace the environmentally pollutant and endocrine disrupters generating plastic material-based cover and rim with a paper-based one. CONSTITUTION: The paper cup is such that the rest part n the upper circumference of the cup body(1) except the cover(2) is curled to the outer direction to form a curling rim(4); a pair of projected lines(5) are formed at interval in the upper circumference of the cup body to the inside direction of the cup body, to not allow the closed cover(2) to be re-taken off; handles(6) are formed at the both sides of the cover(2) to allow the closed cover to be opened easily; the folded line(7) is formed along the outer line of the cover(2), which is folded to the upper direction to be fitted into the projected lines(5) when the cover is closed; and the +-shaped cut part(8) is formed on the upper part of the cover to allow a straw to be put into even if the cover is closed.
