Rarely considered, patents give us an extensive look into the design decisions made by manufacturers with each patent showcasing several pages of descriptions and illustrations. Better yet, patents provide a historical insight through their declared inventor, assignee and filing dates.
Each patent has been sorted by its manufacturer and given a brief description to explain its context. Additionally, a link provided to each patent’s US Patent and Trademark Office claim page for more information.

While patented, no blow molds have yet to been found matching this design. It is assumed, but unproven, that the design was never produced.
