<p>A cap with an induction seal closure for sealing the pouring opening of a container, the induction seal closure comprising a polymer sealing layer (27) capable of being heat-sealed to the top surface of the pouring opening of the container, an aluminium foil (22) for heat-sealing said sealing layer by inductive heating of the aluminium, a first releasing layer (25) between said aluminium foil and said sealing layer and a second releasing layer (21) between said aluminium foil and the top wall of said cap, the releasing power of said second releasing layer (21) being greater than that of said first one (25) so that upon removal of the cap from a sealed container the aluminium foil (22) remains adherant to the sealed container instead of to the cap while yet being easily peel able from the container as a consequence of the presence of said first releasing layer (25). <IMAGE> <IMAGE></p> |
