Corrugated box

Abstract

A corrugated box may include a plurality of sidewall portions separated by a fold line and a plurality of flaps extending from the sidewall portions and isolated from one another by a slot arranged in alignment with the fold line when the flaps are unfolded and the slot may include a fold line end comprising a stress relieving termination and a handle may be provided that may include a cutout line with a return portion foaming a stress relieving end and a series of tabs may be provided for securing a seam of the box.

1 . A corrugated box, comprising:
 a plurality of sidewall portions separated by a fold line; and   a plurality of flaps extending from the sidewall portions and isolated from one another by a slot arranged in alignment with the fold line when the flaps are unfolded, the slot having a fold line end comprising a stress relieving termination.   
     
     
         2 . The box of  claim 1 , wherein the stress relieving termination comprises a dog-bone shape. 
     
     
         3 . The box of  claim 1 , wherein the each of the plurality of flaps include flap edges adjacent the slot and each of the edges comprises a first curved portion diverging from the opposing flap edge, a second substantially straight portion extending to a third curved portion converging toward the opposing flap portion. 
     
     
         4 . The box of  claim 3 , wherein each of the third curved portions converge until they are parallel to one another. 
     
     
         5 . The box of  claim 4 , wherein the third curved portions are connected by a fourth substantially straight portion. 
     
     
         6 . A corrugated box with a sidewall, the box comprising:
 a handle arranged on the sidewall, the handle comprising:
 a cutout line extending through the side wall, the cutout line having a substantially straight bottom portion and two substantially curved end portions defining a return along the top of the cutout line. 
   
     
     
         7 . The corrugated box of  claim 6 , wherein the substantially curved end portion comprises a radius shaped curved. 
     
     
         8 . A corrugated box, comprising:
 a plurality of sidewalls arranged adjacent to each other and defining a seam there between, the sidewalls each comprising a seam edge and having a tab extending from the seam edge, the tab being arranged adjacent an inner or outer surface of the adjacent sidewall and being secured thereto.   
     
     
         9 . The corrugated box of  claim 8 , wherein the tabs from adjacent sidewalls interlock. 
     
     
         10 . The corrugated box of  claim 8 , wherein a first seam edge of a first sidewall includes an upper tab and a lower tab and a second seam edge of a second sidewall includes an upper tab and a lower tab. 
     
     
         11 . The corrugated box of  claim 10 , wherein the upper and lower tabs from the first sidewall are arranged adjacent an inner surface of the second sidewall. 
     
     
         12 . The corrugated box of  claim 11 , wherein the upper and lower tabs from the second sidewall are arranged adjacent an outer surface of the first sidewall. 
     
     
         13 . The corrugated box of  claim 12 , wherein the first seam edge includes a center tab and the center tab is arranged adjacent an outer surface of the second sidewall. 
     
     
         14 . The corrugated box of  claim 12 , wherein the second seam edge includes a center tab and the center tab is arranged adjacent an inner surface of the first sidewall. 
     
     
         15 . The corrugated box of  claim 10 , wherein the upper tab from the first sidewall is arranged adjacent an inner surface of the second sidewall and the lower tab from the first sidewall is arranged adjacent an outer surface of the second sidewall. 
     
     
         16 . The corrugated box of  claim 15 , wherein the upper tab from the second sidewall is arranged adjacent an outer surface of the first sidewall and the lower tab from the second sidewall is arranged adjacent an inner surface of the first sidewall. 
     
     
         17 . The corrugated box of  claim 8 , wherein the plurality of tabs are secured by sonic welding.
