Definitions
- This invention relates to the field of marking instruments, especially, but not necessarily exclusively, writing instruments, in which a marking fluid is delivered to a marking tip from a reservoir.
- Many writing instruments have marking tips which project axially out of the barrel of the instrument in which the reservoir chamber is housed and by means of which the writing instrument is held in the hand in use.
- many marking tips such a ⁇ ball point pens, have tips which function most effectively if the tip is held substantially perpendicular to the surface being written on, but the majority of writers hold writing instruments inclined at an angle to the paper, typically at about 30° away from perpendicular.
- a tube of elliptical cross-section is used.
- the tubular section of the tip is preferably circular in cross-section, which simplifies the tip construction, particularly in the case of a ball point tip in which a spherical ball is retained.
- the tubular member can be made from a hollow component initially formed, such as by deep drawing, with a part-spherical end. Removal of a section of the part spherical end along a plane inclined to the longitudinal axis leaves an edge of circular profile for attachment of the tip.
- the hollow component may have a substantially cylindrical shape, or can vary in cross-section along its length if desired.
- Figure 1 is a transverse cross-section through a tube component utilised in a marking tip according to the invention
- Figure 2 is an axial section through the tube component taken on the line x-x in Figure 1;
- Figure 3 shows the tube profile at the forward end face
- Figure 4 shows the tube component and a ball point tip being assembled together
- Figure 18 is a side elevation of the component of Figure 14 after removal of a section from the closed end thereof;
- Figure 19 is a longitudinal section through the component of Figure 18 with a ball point tip fixed thereto;
