Provided is a pen including an ink reservoir to store an ink; a pen tip which has a proximal end and a distal end opposite to the proximal end and applies an ink to a coating target; an ink guide to guide the ink in the ink reservoir toward the pen tip; and a holder part which has a through hole through which the pen tip is inserted and holds at least the proximal end of the pen tip while exposing the distal end of the pen tip with the pen tip inserted through the through hole. The holder part includes: an ink holding part capable of holding the ink from the ink guide and formed at least partially around a circumference of the through hole; and a first opening opening on an inner circumferential surface that defines the through hole and communicating with the ink holding part.

A fountain pen with a quick-filling coupling includes a nib assembly, a housing with a main tank and a writing tank formed therein, a rotatable finial at an end of the fountain pen opposite from the nib assembly, and a coupling for placing the housing on an ink feed device. A first sealing unit, arranged between the writing tank and the main tank, can be selectively opened and closed for filling the writing tank via the main tank. A second sealing unit, arranged between the writing tank and the nib assembly, can be selectively opened and closed for supplying ink to the nib assembly. A third sealing unit, arranged between the main tank and the coupling, can be opened and closed for filling at least the main tank. The finial is operably coupled to the pen for controlling the opening state of the first and second sealing units.

The present invention, in general, describes a refillable writing instrument. The writing instrument may comprise one or more master reservoir, one or more slave reservoir, one or more slave reservoir gate and one or more master reservoir gate. The slave reservoir may have reducing cross-section, facilitating fluid flow towards nib of the writing instrument. The slave reservoir gate may comprise at least one of blocking element, blocking element seat, one or more gates, one or more covers and a combination thereof. The slave reservoir gate provides a connection between the master reservoir and the slave reservoir. Further, the blocking element rests over the blocking element seat due to gravity, restricting return flow of the fluid to the master reservoir. The master reservoir gate facilitates clean, easy and fast refilling of master reservoir using fluid container or fluid nozzle without the need of opening the master reservoir cap.
