A direct liquid type pen-shaped eyeliner capable of smoothly guiding and ejecting a coating material. A coating material feeder has a coating material discharge region positioned inside a hole portion of an application member and a coating material guide region positioned outside the hole portion and guiding a coating material in a coating material tank toward the coating material discharge region. An upper peripheral groove recessed from an outer peripheral surface toward an inside in a feeder radial direction as a radial direction of the coating material feeder, facing an inner peripheral surface of the hole portion, and allowing the coating material to flow in is formed of resin in the coating material discharge region.

A whitish writing and/or marking fluid, in particular white writing and/or marking fluid, for writing instruments, in particular for capillary writing instruments, or for cosmetic applications, that has a viscosity of less than 30 mPa s (Brookfield, 20° C., cone plate CPE-40), and contains 5 to 15 wt % of an anionic dispersion of a hard resin, an aqueous titanium dioxide dispersion, and a preservative.

A marking pen, comprising: a shaft cylinder; a porous pen core accommodated in the shaft cylinder, and configured to project from, and retract into, an opening part provided at a tip end of the shaft cylinder; an inner cotton accommodated in the shaft cylinder, and filled with an aqueous ink composition to be fed to the pen core, the aqueous ink composition including a water soluble organic solvent in an amount of from 20 mass % to 60 mass %; and a delivery mechanism configured to cause a tip end of the pen core to project from, and retract into, the opening part.

Provided is a direct liquid type pen-shaped eyeliner capable of smoothly guiding and ejecting a coating material. A coating material feeder has a coating material discharge region positioned inside a hole portion of an application member and a coating material guide region positioned outside the hole portion and guiding a coating material in a coating material tank toward the coating material discharge region. An upper peripheral groove recessed from an outer peripheral surface toward an inside in a feeder radial direction as a radial direction of the coating material feeder, facing an inner peripheral surface of the hole portion, and allowing the coating material to flow in is formed of resin in the coating material discharge region.

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.

An apparatus includes a pen. The pen includes a reservoir configured to store a fluid. The pen also includes a tip configured to transfer the fluid from the reservoir onto a surface of an object during writing. The pen further includes a regulator configured to control a flow of the fluid from the reservoir to the tip. The apparatus also includes the fluid stored within the reservoir. The fluid includes a carrier fluid and particles of an X-Ray opaque material.

The application relates to a porous color linker comprising a tip portion configured to deposit indicia on a writing surface; a mixing portion configured to combine a plurality of inks; and a base portion having a first receiving portion configured to receive a tip of a first ink discharge device and a second receiving portion configured to receive a tip of a second ink discharge device.

An aqueous pigmented ink for use in a capillary reservoir system comprises at least one pigment, at least one water-dispersible, film-forming component, about 0.5 to about 4.5 wt % of at least one suspension substance and about 0.01 to about 0.5 wt % of a gel former combination in an aqueous vehicle, the gel former combination comprising at least one mineral gel former and at least one organic thickener.

A bearing assembly includes at least one inner ring and at least one outer ring, and at least one surface of the inner or outer ring is partially colored with an acid-free ink. If the at least one surface includes a surface defect such as a scratch in a black-oxide coating, the acid-free ink may be applied to the scratch to at least partially conceal it.
