Abstract

Claims (37)

1. A bagger device, comprising:

a bag handler configured to handle a web of packaging material configured to define a series of bags configured to be separable from the web, each bag having first and second walls enclosing an interior cavity configured to contain an object therein for shipping, the first wall including an expansion material that has an expandable configuration and that is expandable to an expanded configuration for providing padding to the first wall to protect the object contained within the interior cavity, wherein the bag handler comprises:

a bag opener configured to engage one or both of the first and second walls and form an opening between the first and second walls to enable the object to be received into the interior cavity through the opening,

a sealer configured for sealing closed the opening between the first and second walls to the interior cavity to retain the object therein, and

a separator configured to separate the bag from an adjacent bag in the series of bags after the opening has been sealed; and

an expansion device configured to apply expanding conditions to the packaging material associated with each bag prior to separation from the adjacent bag in the series of bags, the expanding conditions configured to cause the expansion material to expand from the expandable configuration to the expanded configuration.

2. The bagger device of claim 1 , wherein the sealer is a heat sealer configured to form a heat seal between the first and second walls.

3. The bagger device of claim 1 , wherein the bag opener includes an air blower configured to apply air pressure directed to the opening.

4. The bagger device of claim 1 , wherein:

the bag opener includes a plurality of fingers for protruding into the opening and maintaining the opening in an open configuration.

5. The bagger device of claim 1 , wherein the bag opener includes one or more suction devices configured to apply suction to at least one of the walls, configured to pull open the opening.

6. The bagger device of claim 1 , further comprising a bag mover configured for moving the bag to the expansion device and the bag handler.

7. The bagger device of claim 6 , wherein the expansion device is positioned along the bagger device such that the expansion device is configured to expand the expansion material prior to the sealer sealing closed the opening.

8. The bagger device of claim 6 , wherein the expansion device is positioned along the bagger device such that the expansion device is configured to expand the expansion material while the sealer seals closed the opening.

9. The bagger device of claim 6 , wherein the expansion device is positioned along the bagger device such that the expansion device is configured to expand the expansion material after the sealer seals closed the opening.

10. The bagger device of claim 1 , wherein the expansion material is expandable to the expanded configuration for providing thermal insulation to the first wall to thermally insulate the object contained within the interior cavity.

11. The bagger device of claim 1 , wherein the expansion device is configured to apply the expanding conditions to the packaging material associated with each bag prior to sealing of the opening.

12. The bagger device of claim 1 , wherein the expansion device is configured to apply the expanding conditions to the packaging material associated with each bag prior to formation of the opening.

13. The bagger device of claim 1 , wherein the expansion device is configured to direct microwave or RF energy to the packaging material, causing the expansion material to increase to an expansion temperature, the expansion temperature being sufficient to cause the expansion material to expand to the expanded configuration.

14. A bagging system, comprising the bagger device and the web of packaging material of claim 1 .

15. A bagger device, comprising:

a bag handler configured to handle a web of packaging material configured to define a series of bags configured to be separable from the web, each bag having first and second walls enclosing an interior cavity configured to contain an object therein for shipping, the first wall including an expansion material that has an expandable configuration and that is expandable to an expanded configuration for providing padding to the first wall to protect the object contained within the interior cavity, wherein the bag handler includes:

a sealer configured for sealing closed an opening between the first and second walls to the interior cavity to retain the object therein,

a separator configured to separate the bag from an adjacent bags bag in the series of bags after the opening has been sealed, and

a bag folder configured to fold the packaging material over itself to provide the first and second walls; and

an expansion device configured to apply expanding conditions to the packaging material associated with each bag prior to separation of the bag from the adjacent bag in the series of bags, the expanding conditions configured to cause the expandable material to expand from the expandable configuration to the expanded configuration, the expanding conditions configured to cause the expansion material to decrease in density and expand to the expanded configuration.

16. The bagger device of claim 15 , wherein the separator includes a cutter configured to cut the packaging material.

17. The bagger device of claim 15 , wherein the expansion device is configured to heat air and direct the heated air to the packaging material, causing the expansion material to increase to an expansion temperature, the expansion temperature being sufficient to cause the expansion material to expand to the expanded configuration.

18. The bagger device of claim 15 , wherein the sealer is a heat sealer configured to form a heat seal between the first and second walls.

19. The bagger device of claim 15 , wherein the expansion device is positioned along the bagger device such that the expansion device is configured to expand the expansion material prior to the sealer sealing closed the opening.

20. The bagger device of claim 15 , wherein the expansion device is positioned along the bagger device such that the expansion device is configured to expand the expansion material while the sealer seals closed the opening.

21. The bagger device of claim 15 , wherein the expansion device is positioned along the bagger device such that the expansion device is configured to expand the expansion material after the sealer seals closed the opening.

22. The bagger device of claim 15 , wherein the expansion material is expandable to the expanded configuration for providing thermal insulation to the first wall to thermally insulate the object contained within the interior cavity.

23. The bagger device of claim 15 , wherein the expansion device is configured to apply the expanding conditions to the packaging material associated with each bag prior to sealing of the opening.

24. The bagger device of claim 15 , wherein the expansion device is configured to apply the expanding conditions to the packaging material associated with each bag prior to formation of the opening.

25. The bagger device of claim 15 , wherein the expansion device is configured to direct microwave or RF energy to the packaging material, causing the expansion material to increase to an expansion temperature, the expansion temperature being sufficient to cause the expansion material to expand to the expanded configuration.

26. A bagging system, comprising the bagger device and the web of packaging material of claim 15 .
