PROBLEM TO BE SOLVED: To reverse the opening method of an upper lid to the left or the right in a simple operation without detaching a hinge even after the coffining.SOLUTION: This coffin 10 with the reversing lid 10 includes a lower box 12 and the upper lid 13. The upper lid 13 is openably/closably attached to either one side of the left or the right of the lower box 12 by the hinge 16. The lower box 12 is formed by mounting a frame body 12A on an opening end of the lower box body 12A. The hinge 16 capable of opening/closing the upper lid 12 is attached to either one side of the left/right of the frame body 12A. The opening shape of the frame body 12A is so formed that the frame body 12B is reversed to the left/right and mounted on the opening end of the lower box body 12A. The upper lid 13 is divided into a front lid 13A and a rear lid 13R at an intermediate position in its length direction, and the front lid 13A and the rear lid 13B are preferably formed into a front/rear symmetric external shape using an intermediate position in the length direction as a boundary.COPYRIGHT: (C)2009,JPO&INPIT【課題】納棺の後でもヒンジを取り外すことなく、簡単な操作で上蓋の開き方を左右反転する。【解決手段】反転蓋付き棺10は、下箱12と上蓋13とを備える。下箱12の左右いずれか片側にヒンジ16によって上蓋13が開閉可能に取り付けられる。下箱12は、下箱本体12Aの開口端に枠体12Aが載置されてなる。枠体12Aの左右いずれか片側に、上蓋12を開閉可能なヒンジ16が取り付けられる。枠体12Aの開口形状は、下箱本体12Aの開口端に枠体12Bを左右反転させて載置可能になっている。上蓋13は、その長さ方向の中間位置で前蓋13Aと後蓋13Bとに分割され、前蓋13Aと後蓋13Bが上蓋13の長さ方向の中間位置を境界として前後対称な外観になっているとよい。【選択図】図1
