Fully foldable storage box

Abstract

A fully foldable storage box includes a soft bottom, and four hard side boards perpendicularly coupled to four edges of the bottom, and edges of the side boards are connected with each other to constitute a structure having a first folding line along each of four edge corners of the storage box, and a second folding line is disposed perpendicularly at the middle of two selected corresponding lateral boards and a third folding line is disposed perpendicularly at a side of the two lateral boards and proximate to the rear board, such that support strips are formed between the two lateral boards and the rear board respectively, and a liftable hard bottom board is coupled to an internal bottom edge of the rear board, so that and the bottom board can be stacked onto the soft bottom to constitute a fully foldable storage box.

1 . A fully foldable storage box, comprising a soft bottom, and four hard side boards including a front board, a rear board and two lateral boards perpendicularly coupled to four edges of the bottom, and the front board and the rear board being coupled with both edges of the two lateral boards respectively to constitute a storage box having a first folding line disposed along each of four lateral corners, characterized in that:
 a second folding line is disposed perpendicularly at the middle of two selected corresponding lateral boards, and a third folding line is disposed perpendicularly at the two lateral boards and proximate to a side of the rear board, such that support strips are formed between the two lateral boards and the rear board respectively, and each support strip is applied to an internal side of the rear board for supporting an enclosed containing space, and a liftable hard bottom board is coupled to a bottom edge of the internal side of the rear board, so that an end of the bottom board can be coupled to the bottom edge of the internal of the rear board, and the bottom board can be stacked onto the soft bottom.   
   
   
       2 . The fully foldable storage box of  claim 1 , wherein the bottom board has fourth folding line for folding the bottom board into halves. 
   
   
       3 . The fully foldable storage box of  claim 1 , wherein the bottom board has a pull tab disposed at a predetermined position. 
   
   
       4 . The fully foldable storage box of  claim 1 , wherein the front board has a hollow window coupled with a transparent plate. 
   
   
       5 . The fully foldable storage box of  claim 1 , wherein the front board has a handle made of a piece of ribbon and coupled to the exterior of the front board.
