Abstract: A method and device for opening a drink can provided with a frangible obturator which can be pushed back inside the can using a tongue that is fixed in a horizontal position in the middle of the lid by means of a rivet on which the tongue can pivot as a lever to produce an opening which is later closed by a movable case that is adapted on the tongue which is pivoted around the river in order to move onto the opening.

Abstract: The invention concerns a cap (8) for closing a container such as a drink can opened (6) by a breakable seal (5) by means of a pull strip (7) on the lid, the said cap (8) being removably mounted on or around the said pull strip (7) to constitute a movable tab pivoting about the rivet (9) on the lid (4) to be clipped on the peripheral lip (12) crimping the lid (4) on the body (1) of the container. It is characterised in that the clipping means comprise two resilient linking tabs (13, 14) symmetrically arranged in the median horizontal plane P of the cap (8) on either side of the longitudinal axis of symmetry S to form a space (15) in which a lug (16) extends from a horizontal strip (17) holding together the two release tabs (13, 14). The invention also concerns the use of the cap (8) as an advertising vector or an element of a game.
