Abstract

A shock-absorbing package includes a box and a base. The box is configurable to enclose an item and has a box bottom panel. The base has a base bottom panel and defines a recess sized to accommodate a portion of the box including the box bottom panel. The base interfaces with the box in a transport configuration so that the box bottom panel is held separated from the base bottom panel and a volume of air is disposed between the base bottom panel and the box bottom panel. An impact force applied to the base bottom panel generated by dropping the shock-absorbing package onto a surface induces relative movement between the box and the base that expels air from the volume air and decelerates the box at a rate less than a desired maximum deceleration rate.

First claim

What is claimed is:

1. A shock-absorbing package comprising:
a box configurable to enclose an item and having a box bottom panel; and
a base having a base bottom panel and defining a recess sized to accommodate a portion of the box including the box bottom panel, the base interfacing with the box in a transport configuration so that the box bottom panel is held separated from the base bottom panel by at least 1.0 inch and a volume of air disposed between the base bottom panel and the box bottom panel, and
wherein the base is interfaced with the box in the transport configuration so that an impact force applied to the base bottom panel generated by dropping the shock-absorbing package onto a surface induces relative movement between the box and the base that expels air from the volume air and decelerates the box, and
wherein one of the box and the base comprises a tab and the other of the box and the base comprises a slot shaped to accommodate the tab to secure the position of the box relative to the base in the transport configuration and accommodate movement of the tab relative to the slot during the relative movement between the box and the base.

2. The shock-absorbing package assembly of claim 1 , wherein the box bottom panel is separated from the base bottom panel by at least 2.0 inches in the transport configuration.

3. The shock-absorbing package of claim 2 , wherein the box bottom panel is separated from the base bottom panel by at least 3.0 inches in the transport configuration.

4. The shock-absorbing package of claim 1 , wherein the relative movement between the box and the base generates a transient increase in a pressure of the volume of air of at least 1.0 psi.

5. The shock-absorbing package of claim 3 , wherein the transient increase in the pressure of the volume of air is at least 2.0 psi.

6. The shock-absorbing package of claim 1 , comprising one or more features for adjusting a resistance to expulsion of air from the volume of air.

7. The shock-absorbing package of claim 1 , comprising an air vent that is adjustable to change the resistance to expulsion of air from the volume of air.

8. The shock-absorbing package of claim 1 , wherein at least one of the box and the base is made predominantly of cardboard.

9. The shock-absorbing package of claim 1 , wherein the base includes an opening configured to allow at least a portion of the volume of air to escape.

10. A shock-absorbing package comprising:
a box configurable to enclose an item and comprising a box bottom panel; and
a base defining a recess sized to accommodate a portion of the box including the box bottom panel, the base comprising a base bottom panel and frangible tabs that interface with the box to hold the box in a transport configuration in which a volume of air disposed between the base bottom panel and the box bottom panel, the frangible tabs being configured to break in response to an impact force being applied to the base bottom panel generated by dropping the shock-absorbing package onto a surface, wherein breakage of the frangible tabs accommodates relative movement between the box and the base that expels air from the volume air and decelerates the box.

11. The shock-absorbing package assembly of claim 10 , wherein the box bottom panel is separated from the base bottom panel by at least 1.0 inches in the transport configuration.

12. The shock-absorbing package assembly of claim 10 , comprising one or more features for adjusting a resistance to expulsion of air from the volume of air.

13. The shock-absorbing package assembly of claim 10 , comprising an air vent that is adjustable to change the resistance to expulsion of air from the volume of air.

14. A shock-absorbing package comprising:
a box configurable to enclose an item; the box comprising a box bottom panel, a side wall, and a box detent feature; and
a base defining a recess sized to accommodate a portion of the box, the base comprising a base bottom panel and a base detent feature that interfaces with the box detent feature to hold the box in a transport configuration in which a volume of air disposed between the base bottom panel and the box bottom panel; and
an air vent that is adjustable to change the resistance to expulsion of air from the volume of air,
wherein the box detent feature and the base detent feature accommodate relative movement between the box and the base that expels air from the volume air and decelerates the box in response to an impact force being applied to the base bottom panel generated by dropping the shock-absorbing package onto a surface.

15. The shock-absorbing package assembly of claim 14 , wherein the box bottom panel is separated from the base bottom panel by at least 1.0 inches in the transport configuration.

16. The shock-absorbing package assembly of claim 14 , comprising one or more features for adjusting a resistance to expulsion of air from the volume of air.

17. The shock-absorbing package assembly of claim 14 , comprising an air vent that is adjustable to change the resistance to expulsion of air from the volume of air.

18. The shock-absorbing package assembly of claim 14 , wherein the sidewall of the box has a cylindrical shape.

19. A shock-absorbing package comprising:
a box configurable to enclose an item and having a box bottom panel;
a base having a base bottom panel and defining a recess sized to accommodate a portion of the box including the box bottom panel, the base interfacing with the box in a transport configuration so that the box bottom panel is held separated from the base bottom panel by at least 1.0 inch and a volume of air disposed between the base bottom panel and the box bottom panel; and
detent features that secure the position of the box relative to the base in the transport configuration and accommodate the relative movement between the box and the base, and
wherein the base is interfaced with the box in the transport configuration so that an impact force applied to the base bottom panel generated by dropping the shock-absorbing package onto a surface induces relative movement between the box and the base that expels air from the volume air and decelerates the box.

20. The shock-absorbing package of claim 19 , wherein the detent features comprise frangible tabs that break to accommodate the relative movement between the box and the base.
