重屏蔽容器的缓冲体
摘要：
本发明提供一种能够稳定发挥冲击吸收性能的重屏蔽容器的缓冲体。该重屏蔽容器的缓冲体(6)包含第1冲击吸收体(B1)、第2～第4冲击吸收体(B2～B4)以及第5～第8冲击吸收体(B5～B8)，并且至少在第1冲击吸收体(B1)上设置了多个孔，其中，第1冲击吸收体(B1)使纤维方向与冲击输入方向平行地进行组合，吸收与重屏蔽容器端面(1tp)平行的方向上的冲击，并由第1材料构成；第2～第4冲击吸收体(B2～B4)由压缩强度比所述第1材料低并吸收与重屏蔽容器端面(1tp)垂直的方向上的冲击的第2材料构成；第5～第8冲击吸收体(B5～B8)由压缩强度比第2材料的压缩强度低并吸收与重屏蔽容器端面(1tp)垂直的方向上的冲击的第3材料构成。
摘要（英）：

A cushioning body of a cask, stably exhibiting impact absorption performance. The cushioning body (6) is constructed such that the directions of fibers are combined so as to be parallel to the direction of an input of impact and receives impact in the direction parallel to an end surface (1tp) of the cask. Further, the cushioning body (6) includes a first impact absorption body (B1) made from a first material, second to fourth impact absorption bodies (B2-B4) made from a second material that has lower compression strength than the first material and absorbs impact in the direction orthogonal to the end surface (1tp) of the cask, and fifth to eighth shock absorption bodies (B5-B8) made from a third material that has lower compression strength than the second material and absorbs impact in the direction orthogonal to the end surface (1tp) of the cask. Holes are provided in at least the first shock absorption body (B1).
