Sketch Of Dental Floss Cleaning Fork (USA), April 7, 1939

This is a Sketch of dental floss cleaning fork. It was made by Earl Silas Tupper. It is dated April 7, 1939. Its medium is ink on paper.

The earliest designs of Tupperware inventor Earl S. Tupper reflect the flexibility of his ingenuity. Tupper’s ideas, including this dental floss cleaning fork, are clearly laid out in an invention notebook, capturing not only the idea, but his entire process. "Yesterday I made drawings, and the rough frame of my dental floss cleaning fork," he wrote in this sketch. "Today I completed the sample and cleaned my teeth with it. Such things are quickly made and I should have made it when I first conceived the idea."

It is credited Earl S. Tupper Papers, Archives Center, National Museum of American History, 1992.3213.
