The invention relates to a closure lid (20) for a packaging (1) for food products like frozen confectionery, such as ice-cream cups or ice-cream cone sleeves, comprising a plate-shaped centre member (21), and a circumferential non-continuous flange member (22) designed to be selectively in full contact with an inner wall (13) or an outer wall (14) of the packaging (1) and extending essentially in a right angle from the circumference of the plate-shaped centre member (21), wherein the lid (20) is designed such that the plate-shaped centre member (21) can only assume a convex or a concave configuration, and can be manually transferred between the said configurations, and wherein said transfer translates into a change of the angular position of the flange member (22) relative to the plane defined by the circumferential edge (23) of the plate-shaped centre member (21). The invention also relates to a packaging (1) comprising the closure lid and to a packaged frozen confectionery product.
