Apart from some particular designs (the Pullman of Météore, the Asterope of Aurora and the Capless of Pilot) the cap remains one of the essential components of a fountain pen. The cap basically performs two functions, on the one hand it provides the protection of the nib against accidental bumps to the outside, on the other hand it protects the outside from accidental contact with the nib (and especially with the ink brought by the same) and from any leaks. A photo gallery of different types of caps can be found here.
From a technical point of view, many inventions have been applied to the cap, almost always related to the way in which it can be opened or closed (interlocking, screw, snap, now also magnetic) and sometimes also to the way in which it can be inserted on the bottom of the pen to balance the weight or size of the same, as in the case of the Pilot Elite (but there are many precursors) in which for the use of the pen it was necessary to put the cap on it because this was a necessary extension of the body.
A second role played by the cap is to keep the environment around the nib well circumscribed, with the pen closed, so that the ink present on it does not dry out (causing a difficulty in restarting) on the one hand but does not even undergo pressure changes that can cause ink to escape. For this reason, there are both ventilated caps (with the presence of ventilation holes) and caps that are completely sealed. In particular, at the beginning of the 1900s, in order to guarantee against the loss of ink, the presence of a second inner cap began to be introduced as a constitutive part of many caps (significant patents nº US-764227 and nº US-1028382), which encloses the part on which the section is bent and isolates it from the rest of the cap, guaranteeing the seal of the ink. Sometimes this same element is also used as a locking component in the assembly of the clip, which can be mounted in a ring on the same, or wedged between the cap and inner cap by means of a lateral slot.
