A container for powders and granular material (1), such as homopolymers and copolymers, comprises a body (2) defined by a bottom (3) from which a wall (4) is upwardly extended and by an opening (5) delimited by the wall, a closure or cover element (7) being adapted to be arranged on such opening (5), the body (2) having an external flange (11) projecting from the aforesaid wall and spaced from said opening and with which a flanged end edge (19) of said cover (7) cooperates, said edge (19) projecting from a lateral wall (10) of the cover. The lateral wall (10) is sealingly coupled with a wall portion (15) of the body (2) placed between the opening (5) and the external flange (11) of the body, such expedient creating the only seal existing directly between the cover (7) and the body (2), the flanged edge (19) of the cover (7) abutting against the aforesaid flange (11) in a discrete manner and without seal, so as to allow the passage of air between the edge (19) and the flange (11). |
