  • Patent number: 6018853
    Abstract: A knockdown coffin structure includes a bottom plate made of a plurality of layers of paper sheet which has a honeycomb structure. The bottom plate has four edges, each having an arc slot coextensive therewith. Four side plates, made of a plurality of sheets of corrugated paper stacked over and adhered to each other and having an arc extension, are connected to the edges of the bottom plates by having the arc extensions thereof received in the arc slots of the bottom plate to such a position where the side plates are substantially perpendicular to the bottom plate. A holding plate is fit into coffin to be positioned on the bottom plate with edges of the holding plate abutting against and thus securely holding the side plates in the perpendicular position. The side plates also have rib-like projections. A cover plate is positioned on the side plates when the side plates are in the perpendicular position.
