The match-stick filler system is one of many systems designed at the beginning of the century to try to automate the fountain pen ink filling. In this case it was a matter of compressing the rubber tank through the use of a match (or a toothpick or other similar tool) that went to press, through a hole made on the shaft of the pen, on the compression bar.
The problems of this mechanism were mostly related to providing adequate positioning to the pressure bar (it was usually glued). The system was not particularly sturdy, nor elegant, and it assumed however the possession of a match, without which it turned out useless. To this problem some producers had obviated making the clasp dismountable and usable to the place of the match, or creating an opportune protuberance on the head of the cap or using some alternative form in order to furnish an adequate partridge.
The system is therefore quite primitive since no one had found a solution to its most important problem, that in case of breakage of the inner rubber bag, the ink could escape from the hole on the body of the pen with the imaginable unpleasant consequences.
