Today in 1996, US Patent 5553327 A was issued, an invention of Anthony R. Koecher and Kevin M. Schoeller, for their “Hat Made from Cardboard Beverage Container and Method of Making the Same.” Here’s the Abstract:

A hat is constructed from a cardboard product container, for example a 24-pack beer package including a product logo and other graphics thereon. The hat provides a new use for a previously wasted container material, and enables fans or collectors to display their loyalty and support of a particular brand.

This is certainly an odd one to have been patented. I’ve definitely seen hats made from 12-pack containers or similar packages, but I don’t think I knew the process was one that could be, or had been, patented.
