Bag stuffer with improved spring |
摘要 |
A bag stuffer for an expandable bag has an insert movable from a collapsed to an expanded orientation and made of at least one substantially rigid and substantially planar side panel and a bottom panel. The side panel is connected to one end of the bottom panel at a hinge containing a fold between the side panel and the bottom panel and a Z shaped torsion spring biases the insert toward the expanded orientation. The spring has a torso disposed only at the hinge for directly acting on the fold to bias the side panel away from the bottom panel and toward the expanded orientation, and a pair of arms extending at angles from opposite ends of the torso, each arm lying flat against an inside surface of the respective bottom panel and side panel.
