Abstract
A pen dispenser is provided with a tube having an open top for holding a fluid to be dispensed. A valve housing made of plastic and having channels on an inner wall is also provided. There is also an applicator nib made of plastic, along with a plastic spring actuator having a plastic button, and a button retainer. In a closed position the plastic spring actuator is sealingly engaged to the valve housing blocking the flow of fluid out around the applicator nib, and in the open position, the plastic spring actuator is depressed so it is no longer sealingly engaged to the valve housing, allowing the fluid to flow through the channels on the inner wall and exit the dispenser around the applicator nib.
