The product is produced from two substantially identical sheets which rest flat against one another. Each of the sheets is delimited by a bottom, curved edge, which is adjoined by the ends of two side edges of the sheets, which extend upwards, away from one another, from the bottom edge. The two sheets are attached to one another along the bottom curved edge and along at least those parts of the side edges which adjoin the bottom curved edge.
