Abstract
A can (1), in particular for conditioning foodstuff, includes a body composed of a bottom element (2) which is prolonged by a lateral wall (3), the interior surface (9) of the body being at least in part made of tin, the tin surface (9) being partially covered with a coat of protective lacquer (10) to prevent the contact between the tin surface (9) and the foodstuff, the lacquerless tin surface, the “exposed”, being intended to come into contact with the foodstuff in order to set free the tin. The exposed tin surface is constituted of a plurality of “exposed” tin zones (11), which are separated, ones from the others, by lacquered zones (12), the exposed tin zones (11) being distributed on the height of the lateral wall (3), in particular to limit the aesthetic impact due to chemical action of the foodstuff on the exposed tin zones (11).
