The first changes to the simple bevelled cylindrical shape occurred to solve the problem (then very pressing, but which still occurs today) to allow the blocking of the flow of ink when the pen is not used to prevent leakage in the cap. For this reason different solutions were adopted, with as many patents as the famous ''[[Lucky Curve]]'' of [[Parker]], in which the rear part of the feeder was bent until it touched the wall of the tank, thus favoring (at least according to the claims of the project) the reabsorption of the ink.
