A bag opener support apparatus includes a frame having members movable between a collapsed position allowing easy insertion through an end of a flexible container to an expanded position in which the members are movable to a position expanding the interior of the flexible container and the open end of the container to a full cross section shape. The apparatus includes first and second frame members formed of interconnected side legs, with the second frame members pivotally connected to the first frame member for pivotal movement between the collapsed and expanded positions. A lock arm is mountable on one of the second frame members for lockingly engaging the opposed second frame member to maintain the second frame members in the expanded position.
