Abstract
A bag expander, comprising a first wall portion, a second wall portion, a bridge coupling the first and second wall portions together, wherein the first and second wall portions are rotatable about the bridge to lie along a substantially same plane, and an expansion mechanism secured to the bridge, wherein the expansion mechanism is configured to bias the first wall and second wall portions from a collapsed configuration to an expanded configuration.
Claims14
A bag expander, comprising:
- a first wall portion;
- a second wall portion;
- a bridge having a torsion spring secured by an overlaying tape positioned on a top surface of the bridge, and the bridge coupling the first and second wall portions together, wherein the first and second wall portions are rotatable about the bridge to lie along a substantially same plane such that the bridge of the bag expander is configured to receive a bridge of another bag expander of the same kind when stacked together, wherein the secured torsion spring is configured to bias the first wall and second wall portions from a collapsed configuration to an expanded configuration,
- wherein in the collapsed configuration, the top surface of the bridge face toward the first wall portion and the second wall portion, and
- wherein the bridge includes a first and second portion, and defines a hinge area, the first portion being rotatable to the second portion along the hinge area, and
- wherein the torsion spring has a central portion engaged to the hinge area.

A bag expander, comprising:
- a first wall portion;
- a second wall portion;
- a bridge coupling the first and second wall portions together, wherein the first and second wall portions can hinge about the bridge to lie along a substantially same plane such that the bridge of the bag expander is configured to receive a bridge of another bag expander of the same kind when stacked together;
- and
- an expansion mechanism secured to the bridge, wherein:
- in a collapsed configuration, the first and second wall portions are a first distance from each other, and
- in an expanded configuration, the first and second wall portions are a second distance from each other, the second distance being greater than the first distance,
- wherein the expansion mechanism is secured by an overlaying tape, and
- wherein the bridge includes a first and second portion, and defines a hinge area, the first portion being rotatable to the second portion along the hinge area, and
- wherein the expansion mechanism has a central portion engaged to the hinge area.
