Small container for protecting medical samples, etc has strong rigid outer shell, internal thermally insulating padding and central void for sample

摘要

A small container for protecting a small object has a rigid outer shell that is mechanically strong at high temperature, internal thermally insulating padding and a central void for the object. The outer shell is an ellipsoid and about 2.5 mm thick. The outer shell and the padding may each be formed as two half shells. A mineral refractory cement lies between the outer shell and the padding.
