Filling systems

The filling system often referred to simply as snorkel (although this is only one of the components) was introduced by Sheaffer in 1952 with the Snorkel Pen. The system represents an evolution of the previous Touch Down, and the filling mechanism in fact is exactly the same, and uses a pneumatic compression realized in the same way.

The novelty is not so much the way in which the ink is aspirated as the fact that in this case it is no longer necessary to fill the pen by dipping the nib inside the bottle. During the opening phase, in fact, it is possible to extend through the feeder a small metal tube (the snorkel) with an aeration duct that allows the passage of the ink through it instead of through the nib.

Si tratta senza dubbio di uno dei più complessi (e per certi versi affascinanti) sistemi di caricamento mai utilizzati, che permette di non sporcare il pennino e che per questo veniva ampiamente pubblicizzato. Il principale svantaggio resta quello della capienza, in genere infatti l'unità di caricamento che contiene il sacchetto è abbastanza piccola e la penna contiene poco inchiostro.
