Abstract: A blank for a coffin or for a top or bottom part of a coffin, comprising a plurality of largely flat sections limited by essentially straight lines, which sections can be folded in relation to each other along interlying borderlines and joined together to form the intended shape. Each and every one of the said sections comprises a flex-rigid sheet applied to a relatively thin layer forming the outer surface of the coffin. The layer forming said outer surface is made of a flexible material with high tensile strength and extends over the entire outer surface of the blank. Further, said layer constitutes the only connection between the sheet sections of which the blank is comprised.
