The present invention relates to a foldable coffin which comprises: a coffin body comprising a bottom plate and a side plate formed to be extended to the outside of each edge of the bottom plate, wherein each side plate is folded perpendicularly to the bottom plate with respect to the boundary point between the bottom plate and the side plate a coffin cover comprising a cover plate that is vertically symmetrical to the bottom plate of the coffin body and a wall plate formed to be extended to the outside of each edge of the cover plate, wherein each wall plate is folded perpendicularly to the cover plate with respect to the boundary point between the cover plate and the wall plate and a reinforcing part attached to the outer surface of the coffin body and the outer surface of the coffin cover. According to another embodiment of the present invention, a foldable coffin comprises: a coffin body comprising a bottom plate and a side plate formed to be extended to the outside of each edge of the bottom plate, wherein each side plate is folded perpendicularly to the bottom plate with respect to the boundary point between the bottom plate and the side plate a coffin cover opening and closing the coffin body and a reinforcing part attached to the outer surface of the coffin body and the outer surface of the coffin cover. Therefore, the present invention can form a coffin into a foldable type using paper such as a corrugated board. Accordingly, the volume of the coffin is minimized so the coffin is very easily transported or stored. Also, the present invention can layer a reinforcing part on the surface of a corrugated board used for a foldable coffin and supplementally mount support parts on a part of a coffin body and a part of a coffin cover. Accordingly, the overall strength of the coffin is enhanced, thereby preventing the breakage of the coffin during a folding process and also the possible damage during the use of lifting straps.COPYRIGHT KIPO 2016개시된 내용은 접이식 관에 관한 것으로
