Abstract
An elongated extruded plastic corner post for protecting a packaged product. The corner post comprises an outer wall and an inner wall joined at the ends to define a substantially L-shaped cylindrical space therebetween, and one or more integrally formed ribs connecting opposing faces of the inner and outer walls. The corner post protects packaged appliances by directing lateral forces directly to the structural framework of the appliance. In another embodiment, the extruded plastic corner post comprises two elongated legs joined along an inner corner and forming a spring-like profile. The spring-like profile compresses to absorb lateral shocks.
