<p>The device for stabilising drain and/or fill valves for a flexible container for conveying liquids or pulverulent materials is characterised by use of a non-strictly cylindrical valve comprising at least one of the following three members: a lug in a low position formed by an extension of a through valve key, a polygonal proximal flange or a partially polygonal protuberance, and in that a stabilising plate has both a recess corresponding to and following the shape of the said chosen member, and two pads of loops and hooks stuck to the proximal surface and intended to co-operate with pads of loops and hooks sewn and/or stuck to the outer surface of the flexible container opposite the said first pads, the resulting device, when assembled, preventing the valve from rotating on itself when a drain pipe and/or fill pipe is screwed to or unscrewed from the valve.</p> |
