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.

This printing device is provided with a first ink container that contains a first ink; a second ink container that contains a second ink; temperature adjusting units that adjust the temperature of the first ink contained in the first ink container and/or the temperature of the second ink contained in the second ink container; a nozzle that sprays the inks; and a control unit that controls the first temperature adjusting unit and the second temperature adjusting unit.

The present invention, in general, describes a refillable writing instrument. The writing instrument may comprise one or more master reservoir, one or more slave reservoir, one or more slave reservoir gate and one or more master reservoir gate. The slave reservoir may have reducing cross-section, facilitating fluid flow towards nib of the writing instrument. The slave reservoir gate may comprise at least one of blocking element, blocking element seat, one or more gates, one or more covers and a combination thereof. The slave reservoir gate provides a connection between the master reservoir and the slave reservoir. Further, the blocking element rests over the blocking element seat due to gravity, restricting return flow of the fluid to the master reservoir. The master reservoir gate facilitates clean, easy and fast refilling of master reservoir using fluid container or fluid nozzle without the need of opening the master reservoir cap.

An applicator includes a body, an application member, a storage for a liquid applying material, a liquid applying material absorbing body configured to adjust an amount of impregnation, and a first plug configured to cause a rear end side of the application member to be inserted through an insertion hole to hold the application member. The first plug is configured to expose the rear end side of the application member to a side of the storage. A storage region is configured to be increased and decreased by changing a position of a second plug. The absorbing body is mounted to a distal end and is cuttable.

A writing tool includes a writing unit, a capillary member, a dispensing unit, and a replaceable ink cartridge. The capillary member, the dispensing unit, and the replaceable ink cartridge are mounted in the writing unit. The dispensing unit contacts the capillary member and has at least one cutting portion. The replaceable ink cartridge accommodates ink therein and has a film at one end thereof. The replaceable ink cartridge can be installed in the dispensing unit and the film can be pierced and cut by the at least one cutting portion. The ink flows through the film and is delivered to the writing unit via the capillary member and the dispensing unit for writing. The writing tool can thus dispense the ink fluently and leave no residual ink.
