A disposable cup capable of being removed easily from the end of stacked cups and also capable of putting it stably even if the way of removal is incorrect, wherein the outer shape of the cup is so formed that the opening area of the cup is increased gradually from a ground contact side to a drinking port side, a bottom part (130) of the disposal cup which is stored in stacked condition by the insertion of the other cups into it is provided at a position a specified distance apart from a ground contact side end (112) of the cup to the drinking port (111) side, and the bottom part is formed so that it is initially expanded to the ground contact side and, when pushed down to the drinking port side, it is recessed in that direction and expanded to the drinking port side, and then a portion (131) closest to the ground contact side among those bottom parts in the state of being expanded to the ground contact side is formed so that it does not project beyond the ground contact side end (112) of the cup and lies on the drinking port side. |
