Abstract: A new and improved anchor plate for maintaining stacked containers in a stable relation. The anchor plate includes a substantially rigid body for placement between adjacent containers, the body having a plurality of corrugated patterns formed therein, each corrugated pattern having a raised side with a plurality of rows of teeth extending from the raised side for engaging the adjacent containers. The corrugated pattern enhances the penetrating capability of the plate and yet prevents total penetration of the teeth through the entire thickness of the material of the container.
