SYSTEM FOR OPENED OPENING OF AN EASY-OPENING METAL COVER SUBJECTED TO DIFFERENTIAL GAS PRESSURE

摘要

The invention relates to a system and a method for the controlled opening of an easy opening metal lid (2) subjected to a differential gas pressure. Which system (1) comprises: - means (3) for holding said metal cover (2), - means (4) for measuring the differential gas pressure between the two faces (241, 242) of a removable part ( 24) of the metal cover (2), and - means (5) for tilting said gripping member (26), in a controlled and reproducible manner, so as to generate a controlled tearing of said upstream portion of the line of breaking point.
