Constructive arrangement for the opening of a beverage can

A constructive arrangement for the opening of a beverage can, comprising:

• an end wall (10) surrounded by an adjacent peripheral edge (21) of the can (L) and incorporating a first wall portion (11) and a second wall portion (12), which are spaced from each other and breakable in order to form a pouring opening (A1) and a vent opening (A2), respectively;
• an actuation tab (30), affixed to an external central region (13) of the end wall (10) by means of a retaining element (40) and having a pressing end portion (31), positioned on the first wall portion (11), and an extracting end portion (32), positioned on the second wall portion (12) and affixed to the latter, the first and the second wall portions (11, 12) being ruptured, respectively, by the pressing end portion (31) and by the extracting end portion (32), upon the angular displacement of the actuation tab (30) by applying a manual upward force to its extracting end portion (32), said constructive arrangement being characterized in that the actuation tab (30) further comprises a grip portion (33), having a hinge end (33a) affixed to the extracting end portion (32), and a free end (33b), the grip portion (33) being angularly and upwardly displaced, around its hinge end (33a) and by application of a manual force in its free end (33b), from a retracted inoperative condition, in which it remains contained within the contour of the end wall (10), between the latter and the plane of the adjacent peripheral edge (21) of the can (L), and an operative condition, of manual grasp, for applying the upward force for the angular displacement of the actuation tab (30) and in which it has its free end (33b) projecting upwardly from the plane of said peripheral edge (21) of the can (L).
