Abstract
To manufacture a metal can having a tear-open lid and having a storage space for an object above the tear-open lid, the following procedure is used: first, a top edge of the can which has a smaller diameter than the inside diameter of the can body is formed, wherein a transition region (6) is formed. After the tear-open lid has been attached, this transition region is deep drawn so that the tear-open lid (2) is displaced towards the bottom (5) of the can. This produces the storage space. This procedure allows previously formed tear-open lids to be used, which safely guarantees the imperviousness of the seal of the tear-open lid.
