Abstract: The disposable cup (1) has a bottom insert (10), and a substantially truncated conical body (2) having an integral lid (4) and a cup opening. The lid is movable between a raised position and a closed position, possibly via a semi-closed position. The lid has a free edge (5), with a liquid passage opening (6) allowing liquid passage when the lid is in said closed position. The lid is foldably joined to the body along an arcuate first score line (7). The lid further has second score lines (8) arranged at respective ends (14) of the free edge, the second score lines connecting the free edge and the first score line so that, when the lid is pushed towards the cup opening, the lid flips into a position inside the cup opening, the movement of the lid being substantially aided by the folding of the lid along the second score lines. The lid has a larger cross-dimension than the cross-dimension of the body at the closed position of the lid, so that, when the lid portion is pushed further into the body, the lid is bent into a convex shape to seal liquid access along the inside of the cup, and the lid is partly held in the cup in the closed position by frictional forces between the lid and the inside of the cup, and partly by the second score lines causing outer portions of the lid to bend to a substantially vertical position, thereby increasing the force holding the lid in the closed position.

Abstract translation: 一次性杯（1）具有底部插入件（10）和具有整体盖（4）和杯形开口的基本截头圆锥体（2）。 盖可以在升高位置和关闭位置之间移动，可能经由半闭合位置。 所述盖具有自由边缘（5），当所述盖处于所述关闭位置时，具有允许液体通过的液体通道开口（6）。 盖子沿弓形第一刻痕线（7）可折叠地连接到身体上。 盖子还具有布置在自由边缘的相应端部（14）处的第二刻痕线（8），第二刻痕线连接自由边缘和第一刻痕线，使得当盖被朝向杯形开口推动时，盖子 翻转到杯开口内部的位置，盖子的运动基本上由盖子沿着第二刻痕线的折叠辅助。 盖子在盖子的关闭位置处具有比主体的横向尺寸更大的横截面，使得当盖部分被进一步推入主体时，盖子被弯曲成凸形以密封液体接近 沿着杯子的内部，并且盖子通过盖和杯内部之间的摩擦力部分地保持在杯子中，并且部分地通过第二刻痕线将盖子的外部部分弯曲到 基本垂直的位置，从而增加将盖保持在关闭位置的力。
