Abstract: A filter frame is provided by a pair of retaining walls formed of corrugated material and provided with suitable apertures therein with the filter material trapped therebetween. The two frames are spaced by spacing walls which are integrally, foldably connected to at least one of the walls and are secured to the other wall to trap the filter material in place. The retaining walls extend at an angle to each other to prevent collapse of the frame.

Abstract: A one piece carton is described having a central divider with a handle formed of two foldably interconnected parts. The handle is detachably connected to the partition by frangible lines of weakness and is retained in position by a pair of flaps integrally, foldably connected to the partition and overlying lateral flanges of the handle to trap the handle between the flaps and the partition.
