A direct-liquid writing instrument includes a penholder, an ink feeder and a nib. One end of the penholder is provided with a writing portion, and the other end of the penholder is provided with an ink storage portion. The nib is partially inserted into the writing portion. The direct-liquid writing instrument also includes a first baffle and a second baffle that are spaced apart from each other to form an air barrier layer. The first baffle is in contact with the ink of the ink storage portion, and the second baffle is adjacent the writing portion. Additionally, the first baffle is provided with a first air-guiding channel, and a second air-guiding channel is provided between the second baffle and the ink feeder. The ink feeder passes through the first baffle, the air barrier layer, and the second baffle to deliver the ink to the nib.

An input touch pen includes a digitizer refill contained inside a shaft tube and including a contact tip and a stepped tip portion rearward thereof, and a knock member protruding from an opening at a rear end of the shaft tube. The contact tip can protrude and retract through an opening at a tip end of the shaft tube. The stepped tip portion has a larger diameter than the opening at the tip end. A relationship A>X>Y is satisfied, wherein X represents a knock stroke of the digitizer refill, A a distance from the stepped tip portion to an inner surface at the tip end side when the contact tip is sunken inside the opening, and Y a distance that the contact tip is moved by operation of the knock member from a state of protruding from the opening to a state of being sunken inside the opening.

A molten gold writing apparatus is disclosed. The molten gold writing apparatus includes a barrel extending from a top end to an open bottom end. A heating element is positioned within the barrel and includes a rechargeable battery. A cartridge includes a refillable chamber configured to hold a solid gold refill and dimensioned to fit within the heating element. The heating element melts the gold refill and allows it to flow to a tip end of the cartridge. A grip is configured to selectively engage the bottom end of the barrel to cover all but the tip end of the cartridge.

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.

A refill friendly pen body that is configured to adapt to a refill cartridge of various dimensional parameters. An adjustment cylinder is adjustably carried within a barrel to adapt the pen body to a length of the refill cartridge. A grip end of the pen body is configured with an internal collet to compressively engage with a forward end of the cartridge across to retain the forward end of the cartridge in a writing position. The pen body may also be provided with a cap to selectively cover and uncover the writing tip.

An electronic pen main body unit of an electronic pen having a function of a fountain pen includes an ink writing unit in which a cartridge housing liquid ink is fitted to a rear end portion of a pen core, and a pen body is disposed so as to be superposed on the pen core in a direction orthogonal to a coupling direction of the pen core and the cartridge, and an interaction circuit having an electronic part which, in operation, exchanges a signal with a tablet. The interaction circuit is disposed on a side of the pen core opposite the pen body in the direction orthogonal to the coupling direction of the pen core and the cartridge in a state in which the interaction circuit recedes to the cartridge side from a writing end of the pen body in the coupling direction of the pen core and the cartridge.

An ink-type pointer including a housing, a circuit unit, a pen and ink writing module, and an electromagnetic unit. The housing includes an end opening and an accommodation space. The end opening is in communication with the accommodation space. The circuit unit is disposed inside the accommodation space. The pen and ink writing module is disposed inside the accommodation space, and includes a cartridge, a nib, and liquid ink. The cartridge includes a chamber, the nib is connected to the cartridge and extends out of the end opening, and the liquid ink is accommodated in the cartridge and is output through the nib. The electromagnetic unit is disposed inside the accommodation space and includes a magnet and a coil. The magnet includes a through hole, the coil is wound round the magnet and is electrically connected to the circuit unit, and the cartridge passes through the through hole.

A writing, drawing, marking and/or cosmetic device, wherein the device includes at least one shaft and at least one inner body, wherein the at least one shaft is formed from concrete-containing material. The shaft at least partially surrounds the inner body. In the installation position the shaft is secured in an axial direction against axial displacement by a closing cover and a front part and a prestress is formed in the shaft in the axial direction via the closing cover and the front part.

A pen structure containing liquid ink is disclosed herein. It comprises a tube body having a reservoir and an open end; a liquid outflow bushing disposed at the open end and accommodated in the reservoir of the tube body at one end thereof, wherein the liquid outflow bushing has a liquid delivering space and a screw groove disposed on a wall of the liquid delivering space and connected to an end face of the liquid delivering space at one end thereof; and a brush disposed in the liquid delivering space of the liquid outflow bushing and surrounded by the screw groove at one end thereof.

A highlighter with a see-through area comprising a housing having a hollow body and an opening, an ink reservoir disposed inside the housing for storing ink, a nib disposed at the opening and an ink feeder disposed inside the housing for transporting ink from the ink reservoir to the nib. The housing further comprises a cut-out section disposed behind the nib to provide the see-through area for a user. The see-through area allows the user to see a section of text before highlighting. Alternatively, a section of the housing behind the nib can be constructed using transparent material such as plastic to provide a see-through area for a user.
