Abstract (en)
A container bag (10) designed to be inflated before or during filling characterised in that a pressure relief valve (22) is incorporated or incorporatable into the bag body, the valve being connectible to a receiver for exhausted powder or pulverulent matter. The pressure relief valve can be set to give a desired inflation pressure in the FIBC but will permit air to escape above this pressure thereby ensuring that the stitching and seams of the FIBC are not over-stressed to the point of leakage. The valve is connectible to, and preferably is connected to, a receiver for any vented gases and entrained powder. Preferably the receiver is the filling silo (28) so that any expelled powder is returned for refilling. <IMAGE>
