Above, William Painter’s patent drawings for a capped bottle opener. In contrast to the belatedly-invented can-opener, Painter’s bottle opener was designed in conjunction with his patented “crown cap” for Baltimore-based Crown Cork & Seal Company, founded in 1892.
The majority of the early bottle-opener patents are of the cork screw type since most early bottles were corked.
(6 more bottle-opener patents, after the fold…)
