A free-ink writing instrument mat include a nib drying delay component to prevent drying out of the end of the nib of the writing instrument that is located in the writing ink tank thereof. The nib drying delay component is locally arranged around the end of the nib in a liquid tight manner and configured to locally retain ink therein so as to keep the nib end in contact with locally retained ink.

Writing instruments may include nibs having voids for viewing a writing surface when in use. The nib includes a fibrous nib body with an upper writing portion and a lower portion configured to deliver ink from an ink reservoir to the upper writing portion. The nib has one or more elongated beams that defines a void in a two-dimensional plane through which a writing surface can be viewed when in use.

A nib for a refillable free ink writing felt pen includes a body and a dry ink tank including dry ink, the dry ink tank being delimited by the body of the nib and a dry ink tank wall including a water-soluble film.

A nib for a refillable free ink writing felt pen includes a body and a dry ink tank including dry ink, the dry ink tank being delimited by the body of the nib and a dry ink tank wall including a water-soluble film.

A nib for a valve-free free ink writing felt pen including a first end configured to deliver ink to a writing support and second end, opposite the first end, configured to be inserted in a nib receiving part of the valve-free free ink writing felt pen, the first end and the second end defining an axial direction of the nib, the nib including a main body made of porous hydrophilic material and including one or more insert made of porous hydrophobic material, the one or more insert being configured to allow intake of air from the outside of a free ink tank of the valve-free free ink writing felt pen into the free ink tank and avoid ink leakage outside the free ink tank. A valve-free free ink writing felt pen including a nib.

The technology described herein relates to a system and device for saturating an absorbent wicking nib with at least two inks transferred from at least two ink donor structures, to provide a multicolor marker nib. In aspects, a wicking nib device is configured to orient the saturated marking nibs of two different-colored, saturated marker nibs directly adjacent opposing side portions of a porous wicking nib, such that the porous wicking nib simultaneously wicks ink from both contacted marker nibs to create a dual-color marking nib. The wicking nib device may include an aperture for viewing the wicking action.

Provided is a pen including: an ink reservoir configured to store an ink containing decorative particles; and a pen tip configured to apply the ink to an ink coating target. The pen tip includes: a proximal end to which the ink is supplied from the ink reservoir; a distal end opposite to the proximal end and configured to contact the ink coating target; and a groove opening on the outer circumferential surface of the pen tip and extending from the proximal end to the distal end.

A writing implement having a pen tip that can achieve excellent ink outflow performance and an increase in the effective area of a viewer portion allowing recognition of the writing direction, relative to the whole pen tip. The writing implement is a writing implement A which includes a pen tip 20 feeding ink from a writing implement body 10 and having a viewer portion through which the writing direction can be recognized, and is characterized in that the pen tip 20 is configured of, a least, a writing part 30 and a holding body 40 having a viewer portion 43, and the holding portion 40 has a sheet-shaped ink feeder 25 formed with slits or bumps on the surface and inside thereof to produce a capillary action.

The present disclosure relates to a writing instrument comprising a tubular body, a reservoir for an ink composition. The writing instrument comprises a nib comprising a switchable flow material, wherein the switchable flow material is configured to switch between a fluid flow preventing condition and a fluid flow enabling condition by a stimulus. The switchable flow material is configured to control flow of the ink composition from the reservoir to or towards a writing surface.

A is a pen including: an ink reservoir that stores an ink including decorative particles and a pen tip section. The ink reservoir includes a tubular casing member having liquid blocking properties and an ink occlusion material disposed inside the casing member. The casing member has a first opening end and a second opening end. The ink occlusion material includes multiple fibers disposed in the casing member and the multiple fibers respectively having one ends and other ends each disposed at a position corresponding to the first opening end or the second opening end of the casing member.
