Shipping and display container with supporting insert

Abstract

A one-piece shipping and display container is formed from a single unitary blank of corrugated paperboard. The one-piece shipping and display container includes opposed parallel side walls, opposed parallel end walls, bottom flaps, and top flaps all of which are foldably joined to one another for closing bottom and top portions of the one-piece shipping and display container. The one-piece shipping and display container includes a supporting insert panel that is removed from the container when the container is in a knock-down position. The supporting insert panel is inserted back into the container before or after the container is filled with products to provide protection for the products and further enhances the strength of the container during shipping and transportation.

         9 . The one-piece shipping and display container of  claim 1  wherein each of the opposed parallel end walls is defined by a first end wall and a second end wall wherein the first end wall includes two opposed first depending flanges each of which foldably extends from respective opposed lateral edges thereof and wherein the second end wall includes a single second depending flange that extends from a lateral edge thereof. 
     
     
         10 . The one-piece shipping and display container of  claim 9  wherein one of the first depending flanges includes a pair of first locking tabs each of which is engaged with the respective L-shaped slots. 
     
     
         11 . A one-piece shipping and display container formed from a single unitary blank of corrugated paperboard, the one-piece shipping and display container comprising:
 opposed parallel side walls having respective top and bottom flaps foldably joined to respective top and bottom ends thereof and opposed parallel end walls being foldably joined to the side walls so that the respective top and bottom flaps being used for closing bottom and top portions of the one-piece shipping and display container wherein the one-piece shipping and display container includes
 a supporting insert being formed on one of the end walls and both of the side walls or one of the side walls and both of the end walls, the supporting insert being defined by three frangible lines defined by first, second, and third frangible lines intersecting one another wherein the supporting insert panel being removed from the container when the container being in a knock-down position and wherein the supporting insert panel being inserted back into the container before or after the container is filled with products to provide protection for the products and further enhances the strength of the container during shipping and transportation. 
   
     
     
         12 . The one-piece shipping and display container of  claim 11  wherein the first frangible line extends transversely across one of the end walls and both of the side walls and wherein each of the respective second and third frangible lines extends laterally on the respective opposed parallel side walls. 
     
     
         13 . The one-piece shipping and display container of  claim 11  wherein the first frangible line extends transversely across one of the side walls and both of the end walls and wherein each of the respective second and third frangible lines extends laterally on the respective end walls. 
     
     
         14 . The one-piece shipping and display container of  claim 11  wherein each of the top flaps includes a single first L-shaped slot forming in proximity of one end of the top flap and wherein each of the bottom flaps includes a pair of space-apart second L-shaped slots forming in proximity of both ends of the respective bottom flaps. 
     
     
         15 . The one-piece shipping and display container of  claim 11  wherein each of the opposed parallel end walls is defined by a first end wall and a second end wall wherein the first end wall includes two opposed first depending flanges each of which foldably extends from respective opposed lateral edges thereof and wherein the second end wall includes a single second depending flange that extends from a lateral edge thereof.
