    • A disposable cup is equipped at the cup opening with an integrated spill resistant lid structure (S) formed by at least four identical, inwardly foldable lid flaps (F). Each lid flap (F) is connected to the cup body (D) in a first arcuate fold line (L1) concave towards the cup opening (A). Adjacent lid flap side edge regions are interconnected pair-wise along second fold lines (F) which in the unfolded condition of the lid flaps extend from the points (8) of intersection between adjacent first arcuate fold lines (L1) along cup cone generatrices (G) to the free lid flap edge (3, 3'). Each lid flap (F) further comprises a pair of third fold lines (L3) extending straight from the point (8) of intersection to a third fold line end point (9) at the free lid flap edge (3,3'). The third fold line end point (9) is located between the adjacent second fold line end point (12) and the centre (10) of the free lid flap edge (3, 3') so that symmetrical lid flap side wings (W) are formed. The lid flaps (F) in their inwardly folded condition at least substantially abut one another along two adjacent third fold lines (L3)
    • 在杯形开口处装有一次性杯,其具有由至少四个相同的可向内折叠的盖襟翼(F)形成的集成的防溅盖结构(S)。 每个盖翼片(F)在朝向杯形开口(A)凹入的第一弧形折叠线(L1)中连接到杯体(D)。 沿着第二折线(F)成对地相互连接的盖翼片侧边缘区域成对地互相连接,在第二折叠线(F)处,盖翼的展开状态从相邻的第一弧形折叠线(L1)之间的交叉点(8)沿着杯锥母线( G)移动到自由盖片边缘(3,3')。 每个盖翼片(F)还包括在自由盖翼片边缘(3,3')处从相交点(8)直线延伸到第三折线端点(9)的一对第三折叠线(L3)。 第三折线端点(9)位于相邻的第二折线端点(12)和自由盖翼片边缘(3,3')的中心(10)之间,使得对称的盖翼片侧翼(W) 形成。 在其向内折叠的状态下的盖襟翼(F)至少基本上彼此邻接,沿着两个相邻的第三折线(L3)
