A container for filtering devices, comprising: - a tubular lateral wall, - a bottom plate which closes a first axial end of said lateral wall, and - a closing system suitable to close - in an openable fashion - a second and opposite axial end of said lateral wall, wherein said closing system comprises: - an occlusion element, which comprises a cylindrical lower portion suitable to be coaxially inserted into the lateral wall, and an upper portion from which one or more abutment elements suitable to rest on the edge of the second axial end of the lateral wall project, - one or more annular seats obtained coaxially on the outer lateral surface of the lower portion of the occlusion element and singularly suitable to receive an annular sealing gasket, and - a tightening member comprising a ring nut suitable to surround the occlusion element and to be axially constrained to the external of the lateral wall, at the second axial end thereof, and at least one abutment surface suitable to rest on the upper portion of the occlusion element, on the opposite side with respect to the bottom plate, characterised in that the edge of the second axial end of the lateral wall is shaped so as to define a cam profile on which the abutment elements of the occlusion element can slide following a rotation of the latter around the axis thereof, said cam profile being suitable to transform said rotation into an axial displacement of the occlusion element with respect to the lateral wall. - a tubular lateral wall, - a bottom plate which closes a first axial end of said lateral wall, and - a closing system suitable to close - in an openable fashion - a second and opposite axial end of said lateral wall, wherein said closing system comprises: - an occlusion element, which comprises a cylindrical lower portion suitable to be coaxially inserted into the lateral wall, and an upper portion from which one or more abutment elements suitable to rest on the edge of the second axial end of the lateral wall project, - one or more annular seats obtained coaxially on the outer lateral surface of the lower portion of the occlusion element and singularly suitable to receive an annular sealing gasket, and - a tightening member comprising a ring nut suitable to surround the occlusion element and to be axially constrained to the external of the lateral wall, at the second axial end thereof, and at least one abutment surface suitable to rest on the upper portion of the occlusion element, on the opposite side with respect to the bottom plate, - an occlusion element, which comprises a cylindrical lower portion suitable to be coaxially inserted into the lateral wall, and an upper portion from which one or more abutment elements suitable to rest on the edge of the second axial end of the lateral wall project, - one or more annular seats obtained coaxially on the outer lateral surface of the lower portion of the occlusion element and singularly suitable to receive an annular sealing gasket, and - a tightening member comprising a ring nut suitable to surround the occlusion element and to be axially constrained to the external of the lateral wall, at the second axial end thereof, and at least one abutment surface suitable to rest on the upper portion of the occlusion element, on the opposite side with respect to the bottom plate, characterised in that the edge of the second axial end of the lateral wall is shaped so as to define a cam profile on which the abutment elements of the occlusion element can slide following a rotation of the latter around the axis thereof, said cam profile being suitable to transform said rotation into an axial displacement of the occlusion element with respect to the lateral wall.
