A notable variant of the [[safety filler]] is the peculiar filling system adopted by [[Moore]] for its ''[[Non-Leakable]]'' pens, for which three distinct patents were filed, one in 1893 ({{Cite patent|US|501895}}) and two in 1896 ({{Cite patent|US|567151}} and {{Cite patent|US|567152}}). The principle is always to use a recessed nib assembly, but in this case instead of using a helical screw, there is a linear sliding type.

The mechanical simplicity of the system, based on the simple linear sliding of a rod, is the strong point of this mechanism, much more robust and easy to made compared to the complexity of that used in the other retractable pens; all that was required was a good precision in the tolerances of the mechanical machining and good quality gaskets.

Oltre che dalla [[Moore]] il sistema è stato usato anche dalla [[Montblanc]] nei primi modelli [[Rouge et Noir]], portato quasi certamente in Germania alla fondazione dell'azienda da Arthur Eberstein, che in precedenza aveva lavorato proprio per la [[Moore]].<noinclude>
