Method and apparatus for securing a closure in an aperture of a container

An apparatus for handling flowable material, e.g., an intermediate bulk container or IBC, comprises an aperture in the form of an outlet having a closure device in the form of a discharge valve movable between a position to obturate the outlet and a position to allow flow of material through the outlet, and an integral member which is adapted to secure the valve in the obturated position. The integral member is in the form of relatively rigid annular lock or lock ring mounted between the body and a probe. This integral member is thus positioned radially inwardly of the body and has an outer peripheral surface with a step configuration complementary to that of the body.
