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.

The invention relates to a writing implement such as a pen which includes a housing and an internal component in which there is provided a reservoir of ink. The internal component typically includes a portion such as a ballpoint which allows ink to be transferred from the reservoir to a surface to which the said portion is applied. The writing implement and/or internal component is rendered detectable by metal detection and/or X-ray detection apparatus when the internal component is within range of the same so that the internal component is detectable when separated, deliberately or inadvertently, from the remainder of the writing implement.

A thermochromic writing instrument including a writing body, storing a thermochromic ink therein, stored in a barrel; an operation body provided in the barrel to be operated to longitudinally move the writing body; a nib of the writing body configured to be capable of appearing from a front end of the writing instrument, wherein the writing instrument 1 further includes a friction unit, for rubbing handwriting in the thermochromic ink and capable of thermally changing the color of the handwriting by frictional heat generated at that time, and at least one clip body as the operation body, the friction unit 10 is provided at a rear end of the barrel, and the clip body is provided in an area other than the rear end of the barrel.

A pen for cosmetic, writing, drawing, sketching and/or marking purposes includes an inner part and an outer part, wherein at least a portion of the inner part is accommodated in the outer part and is fastened therein. A fastening device between the inner part and the outer part serves to fasten the inner part to the outer part, wherein the fastening device is elastically deformable and is deformed in the installed state against its elastic restoring force. The fastening device is supported between the inner part and the outer part by the elastic restoring force to fasten the inner part to the outer part.
