The retaining apparatus is further pivotably mounted, enabling cooperating with closure means which preferably consists of a twisting device. The advantages of the invention are that a better modelling of the closed bag is possible, that the controlled flap not only retains the bag, but in many instances maintains the shape of the filled bag in a desired way and that the bag closure may be located at a desired location of the bag.
