A crown cap is adapted to be removably coupled to a container. The crown cap has a generally circular central region and a downwardly extending side wall in a generally frusto-conical configuration. The side wall has an interior surface and an exterior surface and an end edge remote from the central region. The exterior surface is formed with a plurality of exterior recesses spaced from the end edge to facilitate shaping of the side wall. The exterior surface has an odd number of recesses. The generally central region includes an annular V-shaped projection facing the end edge between the central portion and the side wall for the receipt of an adhesive for sealing a container.
