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 writing instrument that includes and elongate stylus and at least one stabilizer element. The elongate stylus has a distal inscription tip, a body, and a proximal end. The body is interposed between the distal inscription tip and the proximal end. The at least one stabilizer element extends from the elongate stylus in a direction non-parallel to a longitudinal axis of the elongate stylus. The at least one stabilizer element engages a hand of a user in response to the user grasping the elongate stylus.

A writing instrument having a writing part, which comprises a writing tip, and having a (protective) cap which protects, in particular, the writing tip and is releasably connectable to the writing part. For the releasable connection between cap and writing part, the writing part comprises several connecting means, each with a connecting region which is curved in an ellipsoidal, in particular ball-shaped manner, in a preferred manner balls or semi-spheres, and the cap comprises an internal thread on the inside, wherein the internal thread of the cap, on the one hand, and the connecting means of the writing part, on the other hand, are positioned and aligned in such a manner that, in each case with the cap in a state fastened on the writing part, the connecting region of the respective connecting means engages completely or in part in a or the thread of the internal thread.

A knock type writing tool is provided, in which an appropriate amount of air can be taken in depending on an amount of a thermochromic ink discharged from a pen tip, so that the thermochromic ink can be smoothly discharged from the pen tip, and in which a writing body can rotate surely in conjunction with a rotation of a rotating member. An air hole 63a and a plurality of projection pieces 63b are provided at a rear end portion of a writing body 6. A front surface of a projection and retraction rotating member 7 is provided with a plurality of abutment parts 73, on which respective rear ends of the plurality of projection pieces 63b are to abut, and with a plurality of protrusion parts 72, each of which is formed between the plurality of abutment parts 73 and protruded more forward than the plurality of abutment parts 73. The protrusion parts 72 are respectively inserted in gaps 63c between the projection pieces 63b. An axial length of each projection piece 63b is longer than an axial length of each protrusion part 72, so that a portion of the gap 63c is left more forward than a front end of each protrusion part 72.

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 writing felt pen including a barrel and a nib attached to the barrel, and a deformable pouch comprising a mix of absorbent polymer and fibres, an ink being absorbed in the absorbent polymer and the nib being in fluidic communication with the mix.

Provided is an applicator that uses a stopper ring for temporary coupling between a front barrel and a barrel cylinder and can be easily positioned when coupling. Also provided is an applicator that can be improved in assembly performance during manufacturing.

An applicator which comprises: a barrel cylinder in which an application liquid is stored in a storage portion inside the rear part thereof; and an applying part arranged inside the front part of the barrel cylinder and supplies the applying part with the application liquid stored in the storage portion in the barrel cylinder, and is configured such that: a full coupling portion and a temporary coupling portion are formed on each of a front barrel and the barrel cylinder; the front barrel and the barrel cylinder each have an anti-rotation rib; the anti-rotation ribs are not engaged with each other in the initial coupled state before the temporary coupled state in which the temporary coupling portions of the barrel cylinder and the front barrel are engaged with each other; and, the anti-rotation ribs become engaged with each other in the fully coupled state in which the full coupling portions are engaged with each other.

The diameter of the urging member can be made independent of the outer diameter of the core.

A retractive writing utensil includes a shaft tube, a core stored in the shaft tube in such a manner as to protrude from a front end of the shaft tube when moved forward, and an urging member that is stretched and contracted in the shaft tube in a front-rear direction, wherein the urging member is located adjacent to the core radially outward in such a manner that the center of the urging member is positioned radially outside the core, and urges the core rearward.

An ink reservoir unit for a writing instruments using an ink reservoir tube with which low contamination can be achieved considering environmental problems; and a writing instruments using the same. The ink reservoir tube is composed of a composite material in which a raw material is layered on a paper substrate having paper as a substrate. One end section of the ink reservoir tube is coupled to a connection part formed on a writing member or a relay member that holds the writing member to constitute the ink reservoir unit for a writing instrument. In one preferred aspect, a locking means using a male thread formed on an outer peripheral surface is provided to the connection part to be connected to the ink reservoir tube, and the ink reservoir tube is coupled to the relay member that holds the writing member by the locking means.

Thermoplastic molding composition comprising (A) 40 to 80 wt.-% SAN copolymer (S/AN-ratio 78:22 to 65:35, Mw 80,000 to 250,000 g/mol); (B) 20 to 60 wt.-% SBC block copolymer (monovinylarene 61 to 64 wt.-%) comprising conjugated diene/monovinylarene tapered polymer blocks; and (C) 0 to 5 wt.-% additives and/or processing aids (C); exhibiting ultra-high melt flow with good mechanical, thermal and optical properties, a process for its preparation and its use for the production of bulky and/or thin walled articles.
