Ralph J. Stolle, 91, an inventor who developed the machinery that manufactures pop-tops for metal cans, died Saturday at his Lebanon, Ohio, home.
The businessman and inventor held the patent for the Stolle Can Machinery used throughout the world for production of cans.
In 1923, he founded Stolle Corp., which developed the tab opener and the machinery for its production. He sold the company to Alcoa in 1975 but remained as chairman.
He is listed as an inventor on more than 50 patents.
His daughter, Mary Jo Cropper, said he was humble about his success.
"If you were in a crowd with him, he wouldn't tell you he had the pop-top patent," she said. "Family was really the center of everything with my father."
