ABSTRACT:
An apparatus for inserting a flexible bag into a box having an open upper end. The apparatus includes a frame which supports the box with the upwardly directed open end. A vertically movable member is mounted on the frame above the box for receiving a flexible container thereon. The receiving member has a leading end and a trailing end. The flexible container, when it is received on the receiving member, includes a closed end which is coextensive with the leading end and an open end which is coextensive with the trailing end. The trailing end of the receiving member includes an operative mechanism for folding the open end of the flexible container down around the outer periphery of the open end of the outer container to preferably provide a substantially U-shaped or cuff-like fold. A mechanism is provided for moving the receiving member with the flexible container or bag thereon into the box until the leading end abuts the closed end of the inside of the box so that the flexible container is inserted into the outer container. The folding mechanism is constructed and arranged to continue moving after the leading end abuts the inside of the box so as to fold the open end of the flexible container, in the desired manner, around the outer periphery of the container.
