Device for the stabilisation of drain and/or fill valves for a flexible container intended for the transportation of liquids or pulverulent materials

A device for stabilizing a valve of a flexible container, the device comprising:

• a valve body including a substantially cylindrically shaped portion and a polygonal protuberance protruding from a bottom of the cylindrical portion of the valve body;
• a stabilizing plate including a first recess corresponding to and following the substantially cylindrically shaped portion of the valve body to receive the substantially cylindrically shaped portion of the valve body and a second recess corresponding to and following the shape of the polygonal protuberance of the valve body to receive the polygonal protuberance of the valve body;
• and
• two pads of loops and hooks affixed to a proximal surface of the stabilizing plate, wherein the two pads of loops and hooks co-operate with corresponding pads of loops and hooks affixed to an outer surface of the flexible container to detachably connect the stabilizing plate to the flexible container and prevent the valve body from rotating on itself when a drain pipe or fill pipe is screwed to or unscrewed from the valve body.
