Foldable container

Abstract

A container includes side walls and end walls that can be folded to collapse the container for transport and storage. The end walls are hinged to, and can be folded against, the container floor. The side walls are articulated so that they can be folded in half. A sliding coupling secures the side walls in the unfolded position. The side walls also are hinged to, and can be folded against, the container floor and roof. One end forms an opening that can be closed with a door.

       8 . The container of  claim 1  further comprising a skin associated with at least one of said top frame portion, said pair of opposing side frame portions, said rear frame portion.  
   
   
       9 . The container of  claim 1  further comprising a door associated with said front frame.  
   
   
       10 . The container of  claim 9  wherein said door is movable between a first position wherein said door is associated with, and closes an opening in, said front frame portion and a second position wherein said door is associated with said top frame portion.  
   
   
       11 . The container of  claim 10  further comprising at least one guide roller associated with said door.  
   
   
       12 . The container of  claim 11  wherein said at least one guide roller is connected to said top frame portion by a bracket, said bracket being movable between a first position and a second position.
