In addition to the box-like basic shape G, the inner contour Kof the edge region Bof the shell has at least one corner region (E-E) which is expanded beyond the width B and the length L of the box-like basic shape (G) and is thus adapted at least partially to the contour Kof the edge region Bto be cut of the blank R.
