Advantageously, on the side of a top face (44) of the seats (16), intended to receive in abutment an undercut element (48) of said containers (20), a raised perimeter (52) of each seat (16) is provided to delimit and surround at least partially an annular pocket (56), enlarged with respect to the seat (16) and intended to receive in abutment the undercut element (48) of said containers for pharmaceutical use (20).
