ABSTRACT:
A method for loading and closing containers with flexible open ends employs a chute with an inflatable bladder at the open end, and an elastic closure device. A flexible open end of the container is placed around the end of the chute and the inflatable bladder. The elastic closure device is placed around the open end of the container. The bladder is inflated to secure the container to the chute. Material is delivered into the container through the chute. When a specified quantity of material is loaded into the container, the bladder is deflated causing the container to slide off the chute. When the container slides off the chute, the elastic closure device contracts and closes the flexible open end of container by constricting the size of the flexible open end of the container such that material will not fall out during shipment.
