Abstract: A burial coffin arrangement including a ceremonial casket which can be used a number of times and which is provided with decorative material and which can be placed over or lifted from a disposable inner casket which is made from a material which is not detrimental to the environment when incinerated and when decomposing. The ceremonial casket includes mutually opposing side walls which are pivotally mounted at the top thereof to the upper part of the ceremonial casket. The side walls can be moved towards one another to form wedge-like inwardly inclined outer walls for the inner casket in a traditional manner. When the side walls are brought towards one another, shoulders on the side walls pass into form-bound engagement with the inner casket so that the caskets can be lifted together. When the ceremonial casket is to be lifted away from the inner casket in the case of cremation or when the inner casket is lowered from the ceremonial casket in the case of burial, the side walls are moved apart.
