Container for aerial delivery

Abstract

A container for aerial delivery of a payload is disclosed. The container is comprised of a fixed box, a lid adapted to close the fixed box, and a sleeve surrounding the fixed box. The sleeve is movable between a first, collapsed position and a second, extended position.

1 . A container for aerial delivery of a payload, comprising:
 a fixed box;   a lid adapted to close the fixed box;   a sleeve surrounding the fixed box, wherein the sleeve is open on at least one end and is movable between a first, collapsed position and a second, extended position; and   at least one one-way slide sheet positioned between the fixed box and the sleeve, the one-way slide sheet comprising a first component positioned on the fixed box and a second component poisoned on the sleeve;   wherein the on-way slide sheet is adapted to allow unrestricted movement of the sleeve toward the second position and resists movement of the sleeve toward the first position during impact with the ground.   
     
     
         2 . The container of  claim 1 , wherein the sleeve is maintained in the first position during storage and transportation and transitions to the second position during aerial deployment of the container. 
     
     
         3 . The container of  claim 2 , wherein upon impact with the ground, the sleeve is forced into the first position. 
     
     
         4 . The container of  claim 3 , wherein the movement of the sleeve from the second position to the first position during impact with the ground slows the decent of the container and reduces impact forces over the impact forces experienced by a container without the sleeve impacting the ground. 
     
     
         5 . The container of  claim 1 , wherein one one-way slide sheet is positioned at each corner of the fixed box. 
     
     
         6 . The container of  claim 1 , wherein:
 the first component poisoned on the fixed box is a loop pile fabric; and   the second component positioned on the sleeve is a molded strip having direction hoods facing in one direction.   
     
     
         7 . The container of  claim 2 , further comprising at least one pull strap coupled to the fixed box and the sleeve. 
     
     
         8 . The container of  claim 7 , wherein the pull strap forces the sleeve toward the second position during aerial deployment of the container. 
     
     
         9 . The container of  claim 7 , wherein the pull strap is coupled to a parachute. 
     
     
         10 . The container of  claim 7 , wherein the pull strap is weaved through the lid and a hole in the fixed box, and is secured to the sleeve at a position equally spaced adjacent to each corner of the fixed box. 
     
     
         11 . The container of  claim 1 , wherein the sleeve has a bottom. 
     
     
         12 . The container of  claim 1 , wherein the distance between the first position and the second position is at least 10.1 cm (four inches). 
     
     
         13 . The container of  claim 1 , wherein the container is adapted to deliver the payload undamaged. 
     
     
         14 . The container of  claim 1 , wherein the fixed box comprises numerous layers or is corrugated. 
     
     
         15 . The container of  claim 1 , wherein the container is adjustable to fit the payload. 
     
     
         16 . The container of  claim 15 , wherein the container has at least one of overlapping portions that can be telescoped to fit the payload and wall that expand or collapse to fit the payload. 
     
     
         17 . The container of  claim 16 , wherein the payload is secured within the container without inserts. 
     
     
         18 . The container of  claim 1 , wherein the container has no crumple zone. 
     
     
         19 . The container of  claim 1 , wherein the first and second components are configured to provide a friction breakaway force of at least 0.37 MPa (54 lb/in 2 ) in the restricted, drag direction and/or less than 862 Pa (2 oz/in 2 ) in the opposing, free movement direction.
