A thermochromic writing instrument and a writing body fitted to said thermochromic writing instrument, wherein the writing body comprises an ink storage tube having an outer diameter smaller than an inner diameter of the rotary member; a nib press fitted and fastened into a front end opening of the ink storage tube; a thermochromic ink filled in the ink storage tube; and a tail plug attached at a rear end opening of the ink storage tube, wherein the tail plug has about the same maximum outer diameter as an outer diameter of a rear of the ink storage tube, and is provided with a vent communicated with the inside of the ink storage tube. The writing body is stored in a barrel so as to become longitudinally movably in a backwardly biased condition; both the rear end of the ink storage tube and the tail plug are inserted into the rotary member; and the tail plug abuts on an inner surface of the rotary member.

A marker-making kit for assembling a marking device having a user-determined mixture of marking solution is provided. The kit includes a base unit coupled to a marker positioning mechanism and a press mechanism. A mixing tube holder secures a mixing tube used for collecting a desired amount of one or more marker fluids. A mixed marker solution is combined, including any number of different colors of marker fluid, and used to saturate a marker reservoir. The saturated reservoir may then be transferred to a maker barrel positioned near the press mechanism. By applying an amount of force with a marker compression arm, a completed marker is secured, enclosing the marker reservoir inside a marker barrel.

A shell formed of plastic material of a type which is highly impermeable to solvents found in certain ink compositions forms the body of a pen. A follower and wiping element is placed in the bore of the shell through its rear end opening and a charge of ink is introduced into the shell through its forward ball point assembly receiving opening. A ball point assembly is then snap fitted into this opening. The bore ofthe shell rearwardly of the follower is pressurized substantially above atmospheric pressure and then closed under such pressure by the insertion in the rear end portion of the bore of a closure plug which is secured and sealed by spin welding.

The invention relates to a method for producing an applicator for applying liquid or pasty media (1), comprising a container (3), which stores the medium (1) in question, and an application element (5, 13), which is attached to the container (3) in a usage position in such a way that the application element provides the medium (1) outside the container (3) by capillary action for the application, characterized by the following steps: creating a hose made of thermoplastic plastic by extrusion and inserting the hose into a mold, forming a container (3) closed at the bottom by expanding the hose in the mold, at least partially filling the container (3) located in the mold with the medium (1) in question, separating the container (3) from the hose in order to form an opening accessible at the top side of the container (3), putting the application element (5, 13) into the usage position thereof by at least partially inserting the application element through the opening of the hose, and fastening the application element (5, 13) while preferably simultaneously creating a closure of the container (3) by moving movable mold parts of the mold.

Die Schreibrohre und/oder Reinigungsdrähte für die Schriebspitze von Tuschefullhaltern, die aus einem Grund körper aus Chromnickelstahl bestehen, werden mit einer äußeren, verschleißhemmenden Oberflächenschicht unter Anwendung eines Boridverfahrens versehen. Die Bildung der Boride erfolgt durch ein Pulver-Gasphasen-DIffusions verfahren unter Verwendung eines getrockneten Borid- Pulvers bzw. - Granulats, wobei der Zutritt von Sauerstoff vor, während und nach der Behandlung verhindert ist. Die Behandlung kann dabei unter Schutzgas oder normalen atmosphärischen Bedingungen erfolgen.
