PROBLEM TO BE SOLVED: To provide a waterproof cover for a flexible container bag relating to the container bag capable of storing various kinds of powder and granular substances such as grains, a fertilizer, feed or an industrial powder and granular product such as calcium carbonate and carbon black, resin pellets and crushed resin for recycling to improve an efficiency in handling for transportation and storage, in particular consisting of a novel structure for improving waterproofness of the flexible container bag. SOLUTION: The lower end of a hood waterproof sheet 4 which can be formed in a truncated-cone-shaped or truncated-pyramid-shaped appearance is coupled, in a waterproof manner, with the upper end rim of a rectangular barrel-winding waterproof sheet 3 to form a mantle-like cover body 2. In addition, a coupled fastener portion 5 consisting of a hook side and a loop side of a hook-and-loop fastener is provided on the right and left butted rims, thereby providing the waterproof cover 1 for the flexible container bag.
