1 - 3 . (canceled) 
     
     
         4 . A box of foldable material encasing a container of fluid comprising:
 a base;   at least three connected side walls extending upward from lower side wall edges adjacent to the base to upper side wall edges adjacent to a top and forming a chamber between the base and the top;   said top having an opening therein;   a grip on one of the connected side walls;   a fluid container within the chamber and having a mouth extending through the opening in the top, wherein the lower side wall edges are relatively longer than the upper side wall edges and the top is relatively smaller than the base.   
     
     
         5 . The box of  claim 4  wherein the foldable material is paperboard. 
     
     
         6 . The box of  claim 4  wherein the fluid container is a plastic bag with a mouth extending through the top opening 
     
     
         7 . The box of  claim 6  wherein the mouth has a proximal portion connected to the plastic bag and a distal portion external of the chamber having a cap thereon. 
     
     
         8 . The box of  claim 4  wherein the grip comprises a pair of handles extending from a side wall. 
     
     
         9 . The box of  claim 4  wherein the fluid container is a plastic carton. 
     
     
         10 . The box of  claim 9  wherein the grip comprises an opening in a side wall. 
     
     
         11 . The box of  claim 4  wherein the at least three connected side walls comprise four connected side walls. 
     
     
         12 . A method of forming a box of foldable material encasing a container for holding fluid comprising the steps of:
 forming a black of foldable material having at least three rectangular body panels connected along fold lines, said body panels having top edges and bottom edges such that the bottom edges are relatively longer than the top edges, slotted top flap panels foldably connected to top edges of a plurality of the body panels, and bottom flap panels foldably connected to bottom edges of a plurality of the body panels;   folding the body panels to create an open-ended chamber and inserting a container for holding fluids having a mouth in said chamber so that the mouth extends from the open ended chamber adjacent to top edges of the body panels;   folding the bottom flap panels to form a base and close an end of the open-ended chamber;   folding the slotted top flap panels to close another end of the open ended chamber, so that the mouth extends through the slotted top flap panels.   
     
     
         13 . The method of  claim 12  wherein the foldable material is paperboard. 
     
     
         14 . The method of  claim 12  wherein the fluid container is a plastic bag with a mouth extending through the top opening 
     
     
         15 . The method of  claim 14  wherein the mouth has a proximal portion connected to the plastic bag and a distal portion external of the chamber having a cap thereon. 
     
     
         16 . The method of  claim 12  wherein a body panel has an opening therein comprising a grip. 
     
     
         17 . The method of  claim 12  wherein the fluid container is a plastic carton. 
     
     
         18 . The method of  claim 12  wherein a body panel has an opening and handles are extended through said opening. 
     
     
         19 . The method of  claim 12  wherein the at least three connected body panels comprise at least four connected body panels. 
     
     
         20 . The method of  claim 12  wherein one of the at least three body panels has a side flap that is glued to another body panel when the open ended chamber is formed. 
     
     
         21 . The method of  claim 17  wherein a cap with a handle structure is attached to the mouth of the plastic carton. 
     
     
         22 . The box of  claim 9  wherein the plastic carton has a cap with a handle structure. 
     
     
         23 . A paperboard box encasing a plastic carton comprising:
 a base;   four tapered connected side walls extending upward from relatively longer lower side wall edges adjacent to the base to upper side wall edges adjacent to a top and forming a chamber between the base and the top;   said top having an opening therein;   a grip on one of the connected side walls;   the plastic carton received within the chamber and having a mouth extending through the opening in the top, wherein the top is relatively smaller than the base.
