A method for opening a preserving can comprising a tubular body having two opposite ends closed respectively by a lower lid and an upper lid, wherein the upper lid has a removable upper part delimited by an upper rupturable score line and equipped with an opening upper member, the removable upper part having a surface area at least greater than 90% of a surface area of the upper lid to be able to empty foodstuffs from the preserving can, wherein the lower lid has a removable lower part delimited by a lower rupturable score line and equipped with an opening lower member, the removable lower part having at least one elongated main section having a width of value less than or equal to 3 millimeters and a length of value greater than or equal to 10 millimeters, to be able to drain a liquid juice from the preserving can prior to emptying foodstuffs therefrom, the method implementing the following steps:

• opening the removable lower part by acting on the opening lower member, thus forming in the lower lid a lower drainage opening defined at least by the at least one elongated main section;
• opening at least partially the removable upper part by acting on the opening upper member, creating a draught following which the liquid juice is drained through the lower drainage opening, while retaining the foodstuffs.
