ABSTRACT:
A bag expander for a flexible bag comprising a frame of two U-shaped rods or wires which are slidably connected so that the frame can be expanded when placed inside the bag mouth. Loops on the ends of each frame member slide on the limbs of the other frame member. U-shaped leg members of rod or wire are pivoted by the ends of the limbs to the bases of the frame members respectively so that the frame can be supported above ground. To slow the expander the frame members are telescoped together and the leg members are folded to lie side by side with the frame members.
