摘要:
A piece of porous foil larger than the removable portion of the lid of a can is connected to the under surface of the removable lid portion and overlaps the edges defining the can opening on the interior surface of the lid, whereby liquid is prevented from spurting out of the can with escaping gas upon initial partial opening of the removable portion, and the piece of porous foil is fully removable with the removable lid portion.
