Embodiments of the disclosure can include writing instruments, nibs for writing instruments, and methods of making the same. In one embodiment, the writing instrument includes a reservoir; an ink solution comprising a pigment, the ink solution being housed within the reservoir; a nib disposed at an end of the reservoir and plugging an opening of the reservoir such that the reservoir is closed, wherein a tip of the nib extends outside of the reservoir; and a filament extending within the reservoir, the filament being in fluid communication with a portion of the nib within the reservoir, such that the ink solution travels along the filament and through the nib, by capillary action, wherein the nib and filament are formed such that no more than 50 percent of the pigment present in the nib and filament flow into the reservoir outside of the nib and filament when the writing instrument is stored with the nib up for a period of one day.

Provided are a child and environmentally friendly aqueous based heat transfer disperse dye ink compositions suitable for placing an image on an object and processes of their use. The compositions may include a heat transfer disperse dye and a nonsublimable dye or pigment having a hue representative of the hue of the disperse dye when heat transferred onto a substrate, with either or both of the dyes or pigments having a particle size less than 350 nm, and wherein the ink composition may have a viscosity less than 10 cps at room temperature. A process that uses the ink compositions optionally include marking an intermediate substrate, drying the image, optionally heating the intermediate substrate, optionally placing the inked intermediate substrate in contact with a dye receptive surface of a receptive object, and optionally transferring the image to the receptive object by application of sufficient heat and pressure.

Provided are processes of placing an image on an object that includes optionally filling a hand held nib-based marker with a child and environmentally friendly aqueous based heat transfer disperse dye ink composition, and imaging an intermediate substrate with the marker. A process optionally further includes optionally drying the image, optionally heating the intermediate substrate, optionally placing the inked intermediate substrate in contact with a dye receptive surface of a receptive object, and optionally transferring the image to the receptive object by application of sufficient heat and pressure.

A retractable liquid dispenser device comprising an outer body having a retractable mechanism slidably supporting a liquid dispenser. The liquid dispenser has a supply reservoir and a discharge reservoir with a reservoir valve disposed therebetween. A retractable valve is located in proximity to an open first end of the outer body. A first depression of the retractable actuator opens the retractable valve and moves the liquid dispenser into the extended position for enabling a depression of a distal end of the liquid applicator to open the dispensing valve to permit liquid to flow from the supply reservoir into the dispensing reservoir to dispense the applicator liquid from the distal end of the liquid applicator. A second depression of the retractable actuator moves the liquid dispenser into the retracted position and closes the retractable valve to enclose the distal end of the liquid applicator within the outer body.

A writing tool has a pen tube, a capillary unit, and a dispensing unit. The capillary unit is mounted in the pen tube, and is connected to a nib. The dispensing unit is mounted in the pen tube, and has a communicating tube and a pressing segment connected to the communicating tube. The pressing segment has at least one connecting arm connected to the communicating tube. A dispensing interval is formed between the communicating tube and a periphery of the pressing segment. The communicating tube contacts the capillary unit to make the capillary unit form different compression densities via the pressing segment and the dispensing interval, thus facilitating dispensing ink downward easily through the dispensing interval and providing a better occlusion effect to further avoid ink leakage.

A dry erase ink for a writing instrument. The dry erase ink includes, as the main organic solvent, a solvent selected from the group consisting of n-propyl acetate, isopropyl acetate, or mixtures thereof.

An alcohol-based dry-erasable ink for a writing instrument including, as separation agent, a mixture of glycerol, glycol and pentaerythritol ester.

A writing implement is provided which is designed to draw lines using capillary action, wherein the width of the line can be freely adjusted while the line is being drawn and it is possible to draw lines of almost the same width at the beginning of the use of the writing implement as at the end of use. A felt-tip pen 1 is provided with an ink reservoir 11, a collector 17, and a core 29 for drawing by capillary action the ink that has been dispensed by the collector 17, dispensing the drawn ink from the tip, and adhering same to a paper surface. Even in repetitive writing, the rate of variability in the width of the lines drawn at the end of use with respect to the width of lines drawn at the beginning of use is 10% or less.
