Patent 43,810…

In Japan, patent 43,810 dates to 1917, and a diagram of said patent is shown in Don Bull’s book on Japanese corkscrews on page 50.

Recently a box containing an example of this particular patent was put up for auction, with the box reading “PATENT NO 43810, Improved Bottle Cap Extractor & Bottle Stopper.”

On the reverse of the lid, the usage of the Improved Bottle Cap Extractor is shown:

While the images from the auction listing where the Nakayma Seizo patent was found does not show the corkscrew, it looks as if by unscrewing the the bottle cap extractor from its sheath, a corkscrew will reveal itself.

I was willing to take that chance.

I mean, if they show the corkscrew piece in the directions…

And, an exciting new Japanese patent corkscrew discovery is heading to the island.
