Abstract (en)
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) <IMAGE>
