Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
266 words
A packing for a shell having a case and between the case and the front part of the shell a curved part of smaller diameter, said packing comprising a container made from plastic material having an open end opposite that of the front part of the shell, said open end being adapted to be closed by means of a sealing lid, said container having an inner surface comprising at least one conical part having a conicity directed towards the front part of the shell for limiting the amount the shell is driven into the container when the rear part of the shell is urged forwards by closing of the lid, two molded half-sheaths made from polyureathane, for example, having inner surfaces mating with the outer surfaces of the front of the case and of the rear part of the curved part of smaller diameter of the shell, and a tube fitted over said two half-sheaths and mating with the outer surfaces of said half-sheaths to maintain the half-sheaths in position, said tube having a front part which is conical and middle and rear parts which are cylindrical or conical with a lesser conicity, so that said tube's conical front part bears against said conical part of the inner surface of the container when closing of the lid pushes the rear of the case of the shell forward, said two half-sheaths assuming the exact shape of the outer surfaces of the front part of the case and of the rear part of the curved part of smaller diameter of the shell and the tube which surrounds them.

Claim 3
Dependent Claim
71 words
The packing as claimed in claim 1, wherein said container is arranged so as to contain two similar shells and formed from two parallel housings, molded in one piece, connected together by a dividing wall common to each of them and situated in a plane passing through their longitudinal axes, the front part of said container, at the front part of the shells, being arranged so as to form a handle.
Claim 4
Dependent Claim
62 words
The packing as claimed in any one of claims 1 or 2, wherein, so as to facilitate stacking of the container with other such containers, it comprises, at its front part and its rear part, a very strong slightly projecting belt made from steel, for example, so that, during stacking of the containers, it is the belts which rest on each other.
Claim 5
Dependent Claim
56 words
The packing as claimed in claim 2, wherein the rear part of each of the housings is closed off by a screw plug comprising said sealing lid, said plugs being provided with flanges having a window therein, and a locking piece comprising lugs each engageable in the window of one of the plugs for locking same.
