Headquartered in Baltimore for more than six decades, Painter’s Crown Cork & Seal Company innovated a number of important products including the crown cork bottle cap, bottle opener, and a foot-powered bottle capping machine. By the 1930s, Crown Cork & Seal supplied half of the world’s bottle caps and had factories in Europe, South America, and Asia.
