Abstract
A flat paper lid for a container. The lid is formed with weakened zones such as crease-score lines which enable the lid, that at the time of purchase closes an open-mouthed container holding a ladleable mass of a comestible product, to be quickly and easily converted by manual manipulation into a spoon-like eating implement.
