Abstract: A method places a metallic layer between printing and a semi-permeable container to protect the contents of the container from printed layer inks and adhesives. The method comprises obtaining a semi-permeable container having a polymeric external surface, obtaining a metallic layer, placing the metallic layer against the external surface, and melting at least a portion of the external surface beneath the metallic layer. The metallic layer may include metallized polyester.

Abstract: A surgical rasp for scraping and reshaping bones, particularly useful in cosmetic surgery, comprises a handle and a rasp surfaced insert made from a tungsten carbide attached thereto. The tooth pattern of the rasped surface is created by cutting a plurality of substantially parallel grooves into the insert and subsequently cross cutting a plurality of substantially parallel grooves thereto. Further cross-cuts can be made depending on the particular tooth pattern desired. In a preferred embodiment, the teeth so formed have a trapezoidal-shaped face and a trapezoidal-shaped back which are coextensively integral to create a cutting edge. In an alternate preferred embodiment, the teeth so formed are shaped as three-sided truncated pyramids.
