Provided is a writing implement that maximizes the effective area of a viewer portion allowing visual recognition in the writing direction and that facilitates writing at a high level, at the same time. This writing implement is a writing implement A, including for example, a pen tip 20 that feeds ink from a writing implement body 10 and has a viewer portion 33 allowing visual recognition in the writing direction. The pen tip 20 is comprised of, at least, a writing part 25 and a retainer 30 having the viewer portion 33, an ink feeder portion 26 for feeding the ink from the writing implement body 10 to the writing part 25. The minimum width X of the viewer portion 33 is 3.7 mm or greater and a length Y of the viewer portion 33 is 7.4 mm or greater. The ink feeder portion 26 is arranged on one side of the viewer portion 33. Specifically, the ink feeder portion 26 is preferably adapted to be positioned on a near side during writing (on such a side that the pen tip 20 is located on an obtuse angle side of the ink feeder portion 26).

Provided is an integrated highlighting marker system. The marking system includes a multi-component marker ink comprising a base colorant and a tinting colorant. The marking system also includes a highlighting component configured to transform the base colorant from a first colored state to a second colored state based on the tinting colorant. The highlighting component may be configured to transform the primary base colorant from a colored state to a transparent state to reveal the tinting colorant.

A pen has 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.

Embodiments of the invention are directed to a multi-component nib structure and marking device for selectively generating primary marks and a secondary marks for lettering and shading. The marking device includes a multi-component nib structure, an ink source. The multi-component nib structure generally includes a first nib component, a second nib component, and optionally, a transfer component between the first nib component and the second nib component. In other aspects, the multi-component nib structure may allow lettering with different tones creating, for example, an ombre effect.

A multi-function writing implement includes a pen shaft, a colored pen assembly, and an erasing pen assembly. The colored pen assembly is arranged at one end of the pen shaft. The colored pen assembly includes a cartridge seat, a nib seat, a plurality of colored cartridges, a plurality of relay cartridges, and a plurality of colored ink cotton tubes. The erasing pen assembly is arranged at the other end of the pen shaft opposite to the colored pen assembly. Only one end of the pen shaft may have at least two colors for providing the user to use different colors and the user is not necessary to use two nibs respectively arranged at two ends of the pen shaft by replacing in turn.

A pressure regulating device for a writing tool has a deformable member. Minor air pressure variations in a pen tube of the writing tool can be regulated by deformation of the deformable member. Major air pressure variations in the pen tube can also be regulated by movement of the pressure regulating device. Thus, the pen tube of the writing tool can avoid internal air pressure imbalance caused by external high temperature or low air pressure. Before the writing tool is shipped from a manufacturer, the deformable member is pressurized in advance, such that the minor air pressure variation formed when a pen cap caps the writing tool offsets the air pressure pre-applied to the deformable member. Accordingly, ink inside an internal chamber does not spout out upon removal of the pen cap and the ink will not be overly dispensed or leak during writing.

To provide a writing instrument capable of further improving durability of a writing nib without impairing writing performance even when writing is performed with a heavy writing load. A writing instrument A having a writing part formed of at least a writing nib 30 made of a porous body and a retainer 40 made of a hard material, in which the protrusion amount of the distal end of the writing nib 30 from the retainer 40 is 0.65 mm or more and 1.05 mm or less and/or 40% or more and 65% or less of the thickness of the writing nib 30.

An enclosure apparatus is adopted to a dispensing container having a dispensing side such as but not limited to maker or a candy container. The enclosure apparatus comprises a cap, a lid, and a tubular sleeve having a first end and a second end. The lid is attached to the cap by a hinge and rotatable around the hinge to be in open position or close position. The tubular sleeve is coaxially disposed inside the cap, wherein the cap is relatively slidable along the tubular sleeve. The enclosure apparatus encloses the dispensing side of the dispensing container inside the cap when the cap slides toward the first end of the tubular sleeve and causes the lid in the close position, wherein the dispensing side extends outside the cap when the cap slides toward the second end of the tubular sleeve and causes the lid in the open position.

The application relates to a color linker comprising a base segment including a first portion and a second portion, each of which are configured to allow ink to flow therethrough, and a barrier positioned between the first and second portions, the barrier being configured to prevent the exchange of ink between the first and second portions; a mixing segment adjacent to the base segment, a tip segment adjacent to the mixing segment, and a tip applicator adjacent to the tip segment, the tip applicator being configured to deposit ink onto a writing surface.
