Thepull filler, also called the collar filler, is a filling system that dates back to around 1906 (the patent is nº US-804847 applied for in 1905), when Holland, then still one of the most important manufacturers of fountain pens, introduced a model that used it.

The system, clearly influenced by the crescent filler of which it is essentially an alternative, involves the presence of a metal rod that covers about half the diameter of the body of the pen, connected internally to a pressure bar located on the opposite side of the inner rubber tank.

Tirando la barretta (chiamata collar, da cui l'altro nome del sistema) si comprime il serbatoio in gomma e si consente così il caricamento della penna. Come si può facilmente intuire il meccanismo è sostanzialmente analogo al crescent filler, con il vantaggio di sporgere meno dal fianco della penna, resta comunque non troppo gradevole sul piano estetico.
