Abstract: Apparatus for the transfer of material from one container to another container. The one container is placed in an attachment having a 45.degree. coupling joined by a straight bend to a fixed part with a 45.degree. second coupling. A motor rotates bend relative to the fixed part. Gears ensure an equivalent joint rotation of the attachment with respect to the bend. The one container is turned over and its content flows into the other container. This apparatus is particularly useful with polluting, toxic and radioactive products.

Abstract: In a container comprising a drum and a cover, the cover is locked on to the drum by providing, on the cover periphery, a series of vertical tongues inclined towards the outside in such a way that their end can be located beneath a shoulder of the drum. The part of the cover which bears on the upper edge of the drum is elastically deformable so as to facilitate latching in place. An injection shaft formed in the cover makes it possible to inject into the drum a material for covering the radioactive waste contained therein. This configuration permits an automation of the conditioning and storage of the waste.
