Strengthening insert for a box

Abstract

The invention concerns a strengthening mechanism for use within a corrugated structure. More specifically, the invention provides a corrugated insert that is inserted into a corrugated box. Such insert improves the compression strength of the corrugated box. This is particularly important when such corrugated box has one or more boxes stacked thereon.

1 . The strengthening insert of  claim 1  comprising,
 i. A first surface having a first connecting edge; 
 ii. A second surface connected to said first surface along said first connecting edge, said second surface having a second connecting edge; 
 iii. A third surface connected to said second surface along said second connecting edge, said third surface having a third connecting edge; and 
 iv. A fourth surface connected to said third surface along said third connecting edge, said fourth surface having a fourth connecting edge, said fourth surface being connected to said first surface along said fourth connecting edge. 
 
     
     
         2 . The strengthening insert of  claim 2  wherein said first surface, said second surface, said third surface and said fourth surface are each proximately positioned within an inner surface of a box. 
     
     
         3 . A strengthened corrugated box, comprising:
 i. A partially enclosed box having four connected vertical walls and an enclosed bottom, said enclosed bottom being connected to all four said connected walls, each said vertical wall having an outer surface and an inner surface positioned oppositely to said outer surface, each said vertical wall having a top edge, a bottom edge being parallel to and extending oppositely to said top edge, and a distance extending between said top edge and said bottom edge of each vertical wall; and   ii. A removable insert positioned within said corrugated box, said removable insert comprising at least one side, said removable insert operating to strengthen said corrugated box during compression of said corrugated box.   
     
     
         4 . The strengthened corrugated box of  claim 3  wherein each said connected vertical wall have the same height. 
     
     
         5 . The strengthened corrugated box of  claim 3  wherein said removable insert comprises four connected vertical sides. 
     
     
         6 . The strengthened corrugated box of  claim 5  wherein said removable insert fits along each said inner surface of said corrugated box. 
     
     
         7 . The strengthened corrugated box of  claim 6  wherein each said connected vertical side of said removable insert is connected to two other said vertical sides of said removable insert. 
     
     
         8 . The strengthened corrugated box of  claim 3  wherein said removable insert comprises at least three sides. 
     
     
         9 . The strengthened corrugated box of  claim 8  wherein at least two of said three sides of said removable insert are positioned against two of said connected walls of said box, each said two connected walls facing oppositely to one-another. 
     
     
         10 . The strengthened corrugated box of  claim 9  wherein said two of said three sides of said removable insert face oppositely to one-another and are connected by a third wall positioned between said two sides of said removable insert. 
     
     
         11 . A strengthening insert for a corrugated box having four walls and a bottom, comprising:
 A tri-partitioned insert positionable within said corrugated box, having,
 i. A first surface having a first connecting edge; 
 ii. A second surface connected to said first surface along said first connecting edge, said second surface having a second connecting edge; and 
 iii. A third surface connected to said second surface along said second connecting edge, 
   Said tri-partitioned insert being placeable within said corrugated box whereby said first surface is positioned about one wall of said corrugated box, said second surface is positioned about said bottom of said corrugated box, and said third surface is positioned about another wall of said corrugated box.
