MATERIALS HANDLING APPARATUS

摘要

The invention refers to apparatus (1) for handling flowable material, in the embodiment an intermediate bulk container or IBC (2), comprising an aperture in the form of an outlet (3) having a closure device in the form of a discharge valve (4) movable between a position to obturate the outlet (3) and a position to allow flow of material through the outlet, and an integral member (5) which is adapted to secure the valve (4) in the obturated position. The integral member (5) is in the form of a relatively rigid annular lock or lock ring mounted between the body and a probe (15). This integral member (5) is thus positioned radially inwardly of the body and has an outer peripheral surface with a step configuration complementary to that of the body.
