Reclosable lid of a beverage can
A reclosable metal lid of a beverage can comprising a centre panel in which scorelines are made, allowing to tear out an aperture, a circumferential panel connecting the centre panel with the neck of the can, and a pull-tab attached by a rivet, and a collar for connecting the lid with the can body, equipped with a closing rotatable panel rotating around the rivet axis is, wherein the centre panel ( 4 ) is above the circumferential panel ( 3 ) and has in the connection spot with the circumferential panel ( 3 ) an additional embossing forming a guide-rail, and the rotatable panel ( 5 ) is mounted on the lid on this guide-rail, while the pull tab ( 7 ) is affixed to the rotatable panel ( 5 ) by the rivet ( 6 ), wherein the size of the rotatable panel ( 5 ) corresponds to the size of the centre panel ( 4 ), and the rotatable panel ( 5 ) comprises an aperture which corresponds to a drinking opening of the lid.
1. A reclosable metal lid of a beverage can body comprising: a centre panel in which scorelines are made, allowing to tear out an aperture,
a circumferential panel, and
a pull-tab attached by a rivet, and
a collar for connecting the lid with the can body, equipped with
a closing rotatable panel rotating around the rivet axis, wherein the centre panel ( 4 ) is above the circumferential panel ( 3 ) and has in the connection spot with the circumferential panel ( 3 ) an additional embossing forming a guide-rail,
wherein a radius (R 1 ) of curvature of a surface in a connection spot of the centre panel ( 4 ) and the circumferential panel ( 3 ) is from 0.5 mm to 10 mm and the rotatable panel ( 5 ) is mounted on the lid on this guide-rail, while the pull tab ( 7 ) is affixed to the rotatable panel ( 5 ) by the rivet ( 6 ), wherein the size of the rotatable panel ( 5 ) corresponds to the size of the centre panel ( 4 ), and moreover an aperture is in the rotatable panel ( 5 ), and the rotatable panel ( 5 ) has an aperture corresponding to the size of the scoreline for tearing out the aperture ( 9 ) in the centre panel ( 4 ), and wherein the scoreline for tearing out the aperture ( 9 ) enables tearing out the aperture covering surface from 10% to 50% of the centre panel ( 4 ) surface.
2. The lid according to claim 1 , wherein the centre panel ( 4 ) has a bead ( 8 ).
