包含减缓容装放射性材料之总成与封装盖体间冲击的改良构件之封装体;PACKAGE COMPRISING IMPROVED MEANS OF DAMPENING IMPACT BETWEEN AN ASSEMBLY CONTAINING RADIOACTIVE MATERIALS AND THE COVER OF THE PACKAGING

摘要

本发明有关于一种封装体包含一筒罐用以贮存及/或运送放射性材料，及一总成装着放射性材料容纳在该筒罐之一空穴内被一盖封闭，该封装体包含一系统用以减弱该总成对该盖的冲击，该系统包含至少一可变形的减震装置及该可变形的减震装置之一装载装置。;依据本发明，该等装置之一者系可移动地装在该盖上在一正交于该筒罐之轴线的平面中，并有可相对于该等装置之另一者自行定中心的装置，提供在容装着该等放射性材料的总成上。;According to the invention, one of the devices (42) is mounted moveable on the cover (6) in a plane orthogonal to the axis (8) of the canister, and has means (50) of self-centring relatively to the other of the devices (26), provided on the assembly containing the radioactive materials (16).
