Reusable container for transporting, inspecting, and/or storing a fuel cell
A reusable container for transporting, inspecting, and/or storing a fuel cell or other item may include a crate or box lined with plurality of cushioning inserts to protect a fuel cell placed within the container, and a plurality of straps that extend inwardly from walls of the container and couplable to the fuel cell. The straps are tensionable to suspend at least a portion of the weight of the fuel cell from the walls of the container while a portion of the fuel cell may rest on top of cushioning inserts at the floor of the container.
1. A reusable container for transporting and/or storing a fuel cell including a liquid fuel bladder, the container comprising:
a floor and walls defining an interior space sized to receive and contain the liquid fuel bladder;
at least one resilient cushioning insert sized to nest within the interior space, shaped to cradle and support the liquid fuel bladder above the floor and away from the walls, and having an aperture formed therein which extends therethrough from an inwardly-facing surface to an outwardly-facing surface of the cushioning insert; and
a plurality of straps that extend inwardly from the walls of the container for attachment to the liquid fuel bladder when the fuel cell is placed within the container, the straps being distributed along at least some of the walls on opposing sides of the interior space and being tensionable when attached to the liquid fuel bladder so as to suspend at least a portion of the fuel cell from the walls of the container.
2. The container of claim 1 , wherein each strap is attached to at least one wall of the container.
3. The container of claim 2 , wherein each of the walls includes a frame that supports a panel, and each of the straps is attached to the frame of one or more of the walls.
4. The container of claim 1 , wherein each of the straps has an adjustable section having a length that is adjustable for tensioning the strap.
5. The container of claim 4 , wherein the strap includes a hook or other connector at one end of the adjustable section, the hook being slidable along the strap when the length of the adjustable section is adjusted.
6. The container of claim 1 , wherein the cushioning insert is made of multiple pieces or sections of material.
7. The container of claim 1 , wherein the cushioning insert is made of closed cell foam.
8. The container of claim 1 , wherein the cushioning insert includes an upper surface that slopes downwardly from a first end of the cushioning insert and then upwardly toward a second end of the cushioning insert opposite the first end.
9. The container of claim 1 , wherein the cushioning insert is replaceable with a second cushioning insert having a shape that is different from the cushioning insert.
10. The container of claim 1 , wherein the walls include upstanding side walls supported on the floor and a top wall connected to upper margins of the side walls, to thereby enclose the interior space.
11. The container of claim 10 , wherein the top wall is detachably coupled to the side walls by fasteners.
12. The container of claim 11 , wherein the fasteners include toggle latches.
13. The container of claim 11 , wherein the top wall is removable to allow the fuel cell to be hoisted out of the container.
14. The container of claim 11 , further comprising at least one lift point secured to the top wall and not secured to the side walls, so that, when the fasteners are detached, the lift point can be used to lift the top wall from the side walls of the container.
15. The container of claim 11 , further comprising three or more sets of lift point hardware secured to the top wall along a periphery of the top wall.
16. The container of claim 11 , wherein at least one of the side walls is removable to allow the fuel cell to be removed from a side of the container.
17. The container of claim 1 , wherein at least one of the walls includes an inspection opening that is closed by a cover, the cover being movable away from the inspection opening to allow visual inspection of the fuel cell when inside the container.
18. The container of claim 1 , wherein the walls and/or floor of the container are made of wood, plastic, metal or a composite.
19. The container of claim 1 , wherein said at least one resilient cushioning insert is a single unitary contoured cushioning element that lines both the floor and the walls of the container.
20. A package including the container of claim 1 and the fuel cell positioned within the container, and wherein the fuel cell is attached to the container via the straps.
21. The package of claim 20 , wherein:
the fuel cell includes attachment loops fixed to the outside of the liquid fuel bladder and laterally spaced apart, and
the straps are detachably attached to the liquid fuel bladder via the attachment loops.
22. A reusable container for transporting and/or storing a fuel cell including a liquid fuel bladder, the container comprising:
a floor and walls defining an interior space sized to receive and contain the liquid fuel bladder;
at least one resilient cushioning insert sized to nest within the interior space, shaped to cradle and support the liquid fuel bladder above the floor and away from the walls, and having an aperture formed therein which extends therethrough from an inwardly-facing surface to an outwardly-facing surface of the cushioning insert; and
a plurality of straps that extend inwardly from the walls of the container for attachment to the liquid fuel bladder when the fuel cell is placed within the container, the straps being distributed along at least some of the walls on opposing sides of the interior space and being tensionable when attached to the liquid fuel bladder so as to suspend at least a portion of the fuel cell from the walls of the container,
wherein said at least one resilient cushioning insert includes a lower cushioning insert having three distinct sloped portions including:
a first sloped portion having a first slope;
a second sloped portion having a second slope that slopes upwardly away from first sloped portion; and
a third sloped portion having a third slope that slopes upwardly away from the first and second sloped portions, and wherein:
the first slope is greater than the second slope and greater than the third slope, and
at least one of the first, second, and third slopes is constant along an entire length of the respective first, second, or third sloped portion.
23. The container of claim 22 , wherein said at least one resilient cushioning insert is a single unitary contoured cushioning element that lines both the floor and the walls of the container.
