Abstract

A lidless paper cup includes: a first covering wing connected to one side of the cup opening, the first covering wing having two first protrusions and a snap-fit ​​flange located in a concave area formed between the two first protrusions; and a second covering wing connected to the other side of the cup opening, the second covering wing having two second protrusions and a snap-fit ​​flange located in a concave area formed between the two second protrusions; wherein the first covering wing and the second covering wing can be folded inward toward the cup opening, so that the folding order is not restricted and they jointly cover the cup opening. When pressed down toward the cup opening, the first and second protrusions push and guide each other, so that the snap-fit ​​flange passes over the snap-fit ​​flange and snaps against each other, thereby eliminating the need to identify the sealing order, saving sealing time and reducing operational errors.
