Patent No. 1907994A: Cap

May 9, 2015 By Jay Brooks

patent-logo
Today in 1933, US Patent 1907994 A was issued, an invention of Edward McManus Charles, assigned to Crown Cork & Seal Co., for his “Cap.” There’s no Abstract, but in the description they talk about an “invention relat[ing] to caps for containers and particularly contemplates a cap wherein a sealing ring or cushion is usually employed.” If you keep reading, it’s explained that this crown works better than previous ones for a variety of reasons, even though it looks pretty much the same as other crowns.
