Reinforced slotted void filler

摘要

In a void filler wherein the members are connected and coupled by means of a complementary slot, the slot is reinforced by sandwiching a reinforcing strip between the laminations of the void filler members so as to surround the area of the slot and prevent the member from folding and collapsing in this area. One or more reinforcing strips can be sandwiched between the laminations or sheets making up the void filler member with the grain of the reinforcing strip positioned perpendicular to the parallel flutes of the corrugated material forming the laminated sheets. The reinforcing strip can vary in size from surrounding the immediate area of the slot itself to having the same size as the laminated sheets. An embossed groove can be provided which is slightly larger then the reinforcement strip so that the thickness of the reinforcing strip will be absorbed between the laminations to prevent added thickness in the void filler member.
