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.

A marking instrument having a plurality of removable writing nibs serially aligned so that an operator can remove a spent or fluid-affected writing nib and, thereby, access a fresh writing tip.

A marking implement has a body that has a marking device on one side of the body. The marking device is designed for leaving a mark on a surface. On a distal second side of the body is a strap or straps for removably affixing the body to an appendage/digit of a user (e.g., a single finger or fingers) so the marking implement does not require pressure from another appendage of the user to work. Movement of the marking device across a surface deposits a mark on the surface such as a pen line pencil line, highlighter line, strip of pain, ink line.

A writing instrument may include an upper barrel rotatably connected to a lower barrel. Writing fluid reservoirs may be housed in the upper barrel. A writing tip secured to the lower barrel may be in selective fluid communication with the writing fluid reservoirs. The upper barrel may be rotatable relative to the lower barrel of the writing instrument.

A liquid applicator device for dispensing an applicator liquid from an applicator liquid container. The liquid applicator device comprises a closure having an internal passageway for sealing with the applicator liquid container. A dispensing mechanism is disposed in the internal passageway of the closure. An applicator located in the passageway engaging with the valve element for enabling a depression of the applicator to displace the valve element from the sealing surface to enable the flow of the applicator liquid from the liquid container into the applicator. A capture extends from the valve element for grasping the applicator for inhibiting removal of the applicator from the passageway.

The present invention relates to an ink composition and a writing instrument. The ink composition comprises 10 to 70 wt % of a metallic pigment, 10 to 30 wt % of a resin, 0 to 20 wt % of a colorant, 0 to 20 wt % of an auxiliary agent and a solvent as the remainder; the solvent is a main solvent or a mixture of the main solvent and an auxiliary solvent; the resin includes a film-forming resin and a thickening resin; the present invention uses a low-level monohydric alcohol solvent as the main solvent, a polyvinyl acetal resin as the film-forming resin, and further includes the auxiliary agent, the metallic pigment or the colorants, so the ink composition with such good characteristics as being environmental friendly, drying quickly, being written smoothly and having strong compatibility to general writing surfaces is produced.
