closure for bottles of wine or liquor, like to make a clear break in act

摘要

A closure for bottles for wine or spirits comprises a cylindrical metal shell (2), having a head (2a) and a skirt with an upper portion (2b) and a lower portion (2c), with a pre-incision (3), at a predefined height from the head (2a), that delimits the boundary between the upper portion (2b) and the lower portion (2c). The closure also comprises a cap made of rigid plastic material (4), designed to be received within the metal shell (2) and in the proximity of the head (2a). The height of the plastic cap (4) is greater than the height of the upper portion (2b) of the skirt (2) so that the lower portion of the skirt (2c) and the internal cap (4) have mutually co-operating cylindrical surfaces of substantially constant diameter so that, upon first unscrewing with breaking of the skirt (2) along the pre-incision (3), the lower portion (2b) of the skirt (2) slides out of the plastic cap (4) and drops downwards, leaving exposed a peripheral portion (4a) of the cap (4) projecting underneath the upper portion (2b) of the skirt. Moreover, upon subsequent reclosing, the lower portion (2c) of the skirt (2) does not cover the plastic cap (4) completely again so that it appears evident that the bottle has been opened.
