Abstract: A novelty writing pen constituted by a standard pen having an ink reservoir encased in a sheath and terminating in a writing tip projecting from one end of the sheath, and a molded body configured to represent a familiar object such as a fruit emitting a characteristic odor, the body having a bore therein to receive at least the upper section of the sheath so that the body is carried by the pen. The ink in the pen incorporates an odor-producing component which is compatible therewith. When the pen is put to use, this component causes the surface written on by the pen to exude an odor simulating that of the object carried thereby.

Abstract: The inventive nib body for marking pen is a polygonally prismatic rod-like body made of a porous and rigid material suitable for penetration of the marking ink. Each of the ridge lines formed between the polygonal, e.g. triangular or quadrilateral, end surface and the side surfaces serves as the line-drawing edge so that, when each of the edges has a different length from the others, lines of different widths can be drawn with different line-drawing edges by use of a single nib. Further, the line-drawing edge can be provided with one or more of notches and divided into sections so that the edge can be used for drawing, for example, a double-track line composed of two parallel lines.

Abstract: A combination recorder pen and recorder pen clip is disclosed having interfitting features to facilitate easy assembly and procedure. The marker pen includes a cartridge which is provided with a pair of longitudinally extending bottom ridges, a pair of longitudinally extending side ledges and a pair of forward, downwardly extending projections. The clip includes a flat body within which is punched a pair of longitudinally extending slots of size and position to receive the ridges therein. The clip terminates forwardly in a nose which is designed to stop against the downwardly extending projections. Side flanges extend from the flat body of the clip for frictional engagement with the cartridge sidewalls over the side ledges. In a preferred embodiment, the ridges and ledges include sloping ramps to facilitate sliding engagement of the clip and the cartridge.
