<p>Improved cap system for aluminum and/or steel bottles, consisting on a plastic cap adapted to the neck of an aluminum and/or steel bottle, including its placing procedure and securing. The edge of the cap acts as contact surface for closing and sealing the bottle by thermofusion. The outside cap (1) is made up of an inside edge (2) provided with small teeth (10) on its surface, underneath its upper end (3), resulting in the contact surface for closing and sealing the bottle (8) or container by thermofusion. The thickness of the bottle is reduced at the end zone (4) of its neck (9) facilitating its deformation and ensuring the attachment of the cap on the neck (9) of the bottle by means of introducing a suitable mold (5) by pressure. Thus the cap cannot be moved between projections (6) of the bottle and inside ribs (7) of the cap. <IMAGE></p> |
