EXAMPLE

[0031] The metal lid 1 of the beverage can consists of the collar 2, the circumferential panel 3 and the centre panel 4. The centre panel 4 is above the circumferential panel 3. In the centre panel a scoreline was made, that after tearing out will form an aperture serving for emptying the can. The rotatable panel 5 is mounted on the centre panel. The pull tab 7 is affixed to the rotatable panel 5 by the rivet 6. In addition the centre panel may have a bead 8 in the middle, on which the rotatable panel is wedged. Alternatively the neck of the rivet 6 may go through both the rotatable panel 5 and the centre panel 4. Nevertheless the mounting of the rivet 6 in this case must enable rotation of the rotatable panel 5 around the axis of the rivet 6. In the rotatable panel there is the aperture 9 size corresponding by size with the aperture torn out in the centre panel 4.

[0032] In the connection spot between the circumferential panel and the centre panel there is an additional embossing having radius R1 forming the guide-rail, that on one hand serves to mount the rotatable panel on the centre panel, and on the other hand is its guide-rail. The radius R1 of the curvature of the surface in the connection spot between the centre panel 4 and the circumferential panel 3 is from 0.5 mm to 10 mm. In turn, the radius R2 of the rotatable panel 5 is from 0.55 mm to 11 mm. R2 is the radius of the hitch made on the edge of the rotatable panel. The mutual appropriate adjustment of the radiuses of the guide rail radius and of the rotatable panel hitch causes, that the rotatable panel wedges on the centre panel, and then it may be set in rotational motion around the rivet.

[0033] The aperture in the rotatable panel corresponds with the aperture torn out in the centre panel. The aperture torn out in the centre panel is from 10 to 50% of the centre panel surface. Preferably the diameter D1 of the rotatable panel 5 is from 35 mm to 85 mm. The diameter of the centre panel corresponds with the diameter of the rotatable panel.

[0034] To open the can it is necessary to rotate the rotatable panel, so that the aperture in the rotatable panel is above the aperture in the centre panel. Then it is necessary to tear out the aperture in the centre panel lifting the pull tab so that the nose of the pull tab presses a part of the centre panel inside the can. In order to close the can the rotatable panel is rotated so that it covered the aperture in the centre panel. Reopening the can is carried out by rotating the rotatable panel so as to uncover the aperture in the centre panel.

[0035] Raising of the centre panel above the circumferential panel causes, that the lids stacked in a pile better adhere to each other. Owing to that it is easier to transport them, because they take less space.
