  • Pressurized cartridge for a writing instrument
    Patent number: 4498797
    Abstract: A writing instrument cartridge contains a loose fitting ball follower disposed within the cartridge between an end of a column of paste like ink exhibiting a yield value, and compressed gas contained in a sealed end of the cartridge. The ball follower is adapted to help peel the ink from the tube walls without contact and to prevent the gas from channeling through the ink and escaping from the cartridge past a ball point or nib during writing.
