Abstract
Abstract An ogival shell is covered by an impermeable flexible sheet and sealed therein and the tip of the thus-covered shell is fitted with a protective ferrule and placed in a molded cavity of two half casings which corresponds to the shape of the shell and the ferrule. The casings are then placed in an outer, strong covering such as a box. The ferrule has an outer body in which extends a conical inner body in which the tip is removably inserted, and the outer body is flared at the end opposite that in which the tip is inserted.
