Today in 1931, US Patent 1810630 A was issued, an invention of Conrad Lenz, for his “Combination Container And Bottle Opener.” There’s no Abstract, although in the description it includes this summary:
The present invention relates to a combination container and bottle opener and has for its primary object the provision of a container having attached to the bottom thereof a bottle opening device designed to permit convenient removal of a bottle cap.
A further object of the invention is the provision of a container, preferably in the form of a tumbler having the bottom formed to intimately engage a bottle opening device designed particularly to engage the well known form of bottle cap to remove the cap in cooperation with the tumbler.
If anyone can explain the difference between the “primary object” and the second or “further object” I’ll be mightily impressed. But I especially love how they describe that the bottle cap and the beer glass as “cooperating” to open the bottle. That’s genius.
