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.

1. A case for opening and closing a drink can that has a cylindrical body having a rim whereon is crimped a lid with a frangible obturator, the obturator being adapted to open along a line of least resistance to form an aperture, and a link member having a first part that is generally parallel to and spaced from the lid and a second part that attaches the first part to the lid, the case comprising:a capture shaft adapted to receive the link member and to hold the link member while the case is rotated in a first plane transverse to the lid and in a second plane parallel to the lid;a rear edge with a clip adapted to removably clip to the crimped rim of the can when said capture shaft receives and holds the link member;a reinforced leading edge adapted to engage the frangible obturator and create the aperture when the case is rotated in the first plane; anda bottom adapted to close the aperture, wherein rotating the case in the second plane, after rotation in the first plane, reorients the bottom over the aperture, and clipping said clip to the crimped rim closes the aperture,wherein said capture shaft has a longitudinal axis perpendicular to the second plane, a chamber at an end of the longitudinal axis for receiving the link member, wherein an entrance to said chamber has means for holding the link member,wherein said capture shaft has walls that get closer together approaching said chamber and said means for holding the link member comprises a throat with a diameter smaller than a diameter of said chamber. 2. The case of claim 1, wherein said capture shaft has walls parallel to the longitudinal axis and said means for holding the link member comprises flexible tabs that extend across said capture shaft. 3. A case for opening and closing a drink can that has a cylindrical body having a rim whereon is crimped a lid with a frangible obturator, the obturator being adapted to open along a line of least resistance to form an aperture, and a link member having a first part that is generally parallel to and spaced from the lid and a second part that attaches the first part to the lid, the case comprising:a capture shaft adapted to receive the link member and to hold the link member while the case is rotated in a first plane transverse to the lid and in a second plane parallel to the lid;a rear edge with a clip adapted to removably clip to the crimped rim of the can when said capture shaft receives and holds the link member;a reinforced leading edge adapted to engage the frangible obturator and create the aperture when the case is rotated in the first plane; anda bottom adapted to close the aperture, wherein rotating the case in the second plane, after rotation in the first plane, reorients the bottom over the aperture, and clipping said clip to the crimped rim closes the aperture,wherein said capture shaft has a longitudinal portion perpendicular to the second plane and a lateral portion parallel to the second plane. 4. The case of claim 3, wherein said longitudinal portion of said capture shaft has walls that get closer together approaching said lateral portion. 5. A case for opening and closing a drink can that has a cylindrical body having a rim whereon is crimped a lid with a frangible obturator, the obturator being adapted to open along a line of least resistance to form an aperture, and a link member having a first part that is generally parallel to and spaced from the lid and a second part that attaches the first part to the lid, the case comprising:a capture shaft adapted to receive the link member and to hold the link member while the case is rotated in a first plane transverse to the lid and in a second plane parallel to the lid;a rear edge with a clip adapted to removably clip to the crimped rim of the can when said capture shaft receives and holds the link member;a reinforced leading edge adapted to engage the frangible obturator and create the aperture when the case is rotated in the first plane; anda bottom adapted to c lose the aperture, wherein rotating the case in the second plane, after rotation in the first plane, reorients the bottom over the aperture, and clipping said clip to the crimped rim closes the aperture,wherein said bottom has a bulge that engages the aperture when said clip is clipped to the crimped rim and closes the aperture. 6. A method for opening and closing a drink can having a cylindrical body on which is crimped, through a peripheral crimping rim, a lid provided with a frangible obturator that may be torn apart along a line of least resistance in order to provide a partial aperture by using a case that is removably fitted, through a capture shaft, on a linking joint fixed to a center of the lid, the method comprising the steps of:pivoting the case in the vertical plane by lifting one end close to the peripheral crimping rim around the linking joint, so that the case acts as a lever and pushes in the frangible obturator by means of another end provided with a reinforced leading edge; androtating the case in the horizontal plane around the linking joint so as to close the aperture by clipping the one end on the peripheral crimping rim,wherein the case is secured to the lid by vertically pressing the linking joint into a capture shaft of the case, where a leading edge of the case is normal to the frangible obturator and a rear portion of the case is normal to the peripheral crimping rim so as to form the one end for pushing in the frangible obturator. 7. A method for opening and closing a drink can having a cylindrical body on which is crimped, through a peripheral crimping rim, a lid provided with a frangible obturator that may be torn apart along a line of least resistance in order to provide a partial aperture by using a case that is removably fitted, through a capture shaft, on a linking joint fixed to a center of the lid, the method comprising the steps of:pivoting the case in the vertical plane by lifting one end close to the peripheral crimping rim around the linking joint, so that the case acts as a lever and pushes in the frangible obturator by means of another end provided with a reinforced leading edge; androtating the case in the horizontal plane around the linking joint so as to close the aperture by clipping the one end on the peripheral crimping rim,wherein the case is secured to the lid by vertically pressing the linking joint into the capture shaft of the case, then moving the case through a radial translation in a horizontal plane in parallel to the lid, wherein a leading edge of the case is normal to the obturator and a rear portion of the case is close to the peripheral crimping rim so as to form the one end for pushing in the frangible obturator. 8. The method according to claim 7, further comprises the step of radially translating the case in the horizontal plane from a pre-opening position so that the case stays completely enclosed inside a space defined by the peripheral crimping rim to a post-opening position, wherein the one end clips onto the peripheral crimping rim so as to be superimposed over the aperture and thus close the aperture.
