TODAY’S PATENT – KEYRING POCKET PEN
Today’s patent was invented by Thomas Nielson on December 4, 1990, bearing patent no. 4,974,982.
This invention pertains to a writing instrument, specifically one that is small and can be linked to a keyring. It also applies to writing instruments in general. Similar internal threads are supplied on the open ends of the cap and barrel, and the other end of the pen holder has a circumferentially extended, expanded abutment that is placed at regular intervals. An enlarged pen holder with a length greater than the cap and a pen tip at one end, as well as a short elongated cap with a first open internally threaded end, are given. The second end of the cap has a keyring attachment structure, and the second end of the barrel is closed. The primary goal of this innovation is to create a writing instrument that can be attached to a keyring in a horizontally compact condition as a new adornment.
