Claim:
Container in the form of a drum for stabilising and confining solid waste comprising a side wall with lower and upper end edges each provided with a blocking member, at least one of said two blocking members being of the inserted type in order to close an opening defined by the associated end edge, said inserted blocking member-comprising two faces, one interior and the other exterior, connected by a peripheral outline, peripheral outline of the inserted blocking member and an interior outline of the associated end edge of the side wall having generally complementary shapes on at least one portion of their respective heights, in such a way that said inserted blocking member comes to be housed on at least one portion of its height in a space surrounded by said end edge of the side wall and comes to bear against said end edge, characterised in that peripheral outline of the inserted blocking member is provided with at least one protruding lug and extending over its circumference, which has a section of generally triangular shape formed of an inclined surface, directed towards the interior face with an inclination such that said inclined surface moves away from a central axis of said blocking member in a direction from the interior face to the exterior face according to an angle between 20° and 40° in relation to said axis, followed by a surface forming a flat, directed towards the exterior face, and in that the interior outline of the end edge of the side wall has at least one recess extending also over its circumference, able to receive said lug in order to ensure a locking of said inserted blocking member on said side wall, the recess having a section comprising an inclined surface, directed towards the exterior of the container with an inclination such that said inclined surface moves away from a central axis of said side wall in an interior towards the exterior direction according to an angle between 20° and 40° in relation to said axis, followed by a surface forming a shoulder, directed towards the interior of the container.
