<p>Cores (6) rivetted opening sections (2) and handles (1) of cans for potables are located near the outer edge of the cutting sections and on the inner surface of said opening sections the annular tops of the conical mouths (3), folded into two leaves, of resilient silicon rubber are adhered with dots using harmless silicon adhesive and the lower flanges of the conical mouths are adhered on inner surface of the top sections of the can, so that the opening section (2) and the mouths (3) adhered by the dots adhesive layer (9) are separated the moment the conical mouths (3) are jumped out by elasticity when said opening sections (2) are opened by pulling up them. Thus potables can be drunk hygienically.</p> |
