Abstract

A multifunctional pen comprises an outer shell (1) having at least one partition (3) in its inner space, which separates the inner space into two chambers (a,b), at least one of which is to be filled with working fluid directly, thus increasing the volume of working fluid. At the external ends of both chambers writing, drawing or working tips (2,5) are provided. The working fluid filled in the second chamber b may be used to write and draw on the surface of materials, on which writing or drawing with a common ink or the like is not possible or may be used for correcting writing or drawing errors.

Description

  • The present invention relates to a multifunctional pen for writing or drawing appliances.
  • The user of a common pen generally must correct errors made during the writing process by applying a correcting fluid taken from a correcting fluid dispenser. Sometimes the user may also have the difficulty of writing and drawing on different materials. With a common pen such problems cannot be solved directly.
  • The problem underlying the present invention is to provide a multifunctional pen, that can be used not only for writing and drawing on paper but also for correcting errors and/or for writing and drawing on materials different from the normal paper.
  • According to the invention a multifunctional pen comprises the features of claim 1. The working fluid may be a physically covering-up fluid, a chemically colour-fading fluid or a rather strongly adhesive coloured fluid not only capable of correction but also capable of writing and drawing on such materials as metal, glass and ceramics.
  • The type of the working tip is determined by the use of the pen. If the working fluid is a water-­soluble or diluted oily fluid, the working tip can be made of a bundle of fibre with good permea­bility, foamed plastics, foam rubber, ceramics, etc.. If a suspension or emulsion is used as working fluid, the working tip can be made of metal, nylon, plastics or other material, which is non-permeable for the fluid. In this case, the working fluid flows out through a gap between the working tip and the outer shell, the position of the displacement of the working tip preferably being controlled by a spring. If the working tip is covered by a cap when not in use, the working tip can also be made of a material having good permeability for certain types of suspension or emulsion used as a working fluid.
  • As the pen of the present invention utilizes a part of the shell directly for the filling of working fluid, the volume of working fluid to be housed in the shell is increased. Further, with the pen of the invention the special characteristics of some working fluids may be utilized to accomplish the writing and drawing on the surface of specific materials.
  • The writing and/or drawing part of the pen of the present invention comprises an outer shell and a pen tip used for writing and drawing, and other parts for storing and feeding an ink similar to common pens solely used for writing and drawing.
  • Other advantageous aspects of the present invention are mentioned in the subclaims.
  • Further aspects of the invention will become apparent from the following detailed description of several preferred embodiments of the invention with reference to the accompanyingdrawings in which
    • Fig. 1 is a longitudinal side view, partly in section, of a multifunctional pen of the present invention,
    • Fig. 2 is a longitudinal part-section showing another working tip of a multifunctional pen of the present invention,
    • Fig. 3 is a longitudinal part-section of still another embodiment of a multifunctional pen of the present invention,
    • Fig. 4 is a longitudinal part-section of a further embodiment of a multifunctional pen of the present invention,
    • Fig. 5 is a longitudinal part-section of another embodiment of the multifunctional pen of the present invention.
  • As shown in Fig. 1 a multifunctional pen has an outer shell 1 and a writing-drawing part comprising a writing or drawing apparatus 2. A partition 3 within the outer shell 1 subdivides the inner space of the outer shell 1 into first and second chambers a and b. The second chamber b is filled with a working fluid 4. At the external end of the second chamber b a working tip 5 is installed, the type of which being determined by the use of the pen.
  • The working tip 15 shown in Fig. 2 is made of a fibre bundle of good permeability for the working fluid.
  • In the embodiment of Fig. 3 the working tip 16 is made of a material which is permeable for the working fluid. In operation the working fluid flows out through a gap between the working tip 16 and the outer shell 1. The displacement of the working tip 16 is controlled by a pressure spring 6, which urges the working tip 16 against a cap 7 which surrounds and partly covers the outside of the working tip.
  • In the embodiment of Fig. 4 the second chamber b is filled by some kind of felt or floss used as a liquid storing body. Within the working tip 17 a hole 9 is drilled, wherein a tubing 10 is inserted to allow outflow of the working fluid under operation of the working tip 17.
  • The working tip 18 of the embodiment shown in Fig. 5 is made of a material which is nonpermeable for the working fluid similar to the working tip 16 of Fig. 3. The working tip 18 in cooperation with cap 19 practically acts as a valve, i.e. the conical contour 20 of the working tip 18 mates with the cap 19 acting as a valve seat. When the working tip 18 is pressed inwardly, it is separated from the valve seat 19, so that the working fluid can flow out through the gap between the valve seat and the working tip. When no more fluid is required, the pressure effected by the user on the working tip is released and the pressure spring 6 forces the sealing parts 19 and 20 tightly together to close the valve and thus to prevent the working fluid from flowing out further from chamber b. The outside surface of the working tip 18 is wrapped with a layer 11 of a material having a certain degree of fluid-permeability.
  • A permanent magnet ring 12 is slipped on the outside surface of the outer shell 1 at a position corres­ponding to the second chamber b. Within the second chamber b a magnet actuated plunger 13 is placed oppositely to the magnet ring 12 in a corres­ponding position. When applying the working fluid, the permanent magnet ring can be moved in direction towards the working tip 18 thus activating plunger 13 to move in the same direction and thereby exerting a pressure on the working fluid within chamber b in order to force the working fluid out of chamber b. If the working fluid is a supsension or emulsion, one or several through-holes 14 may be drilled in the magnet actuated plunger 13 to utilize its movement for mixing the working fluid homogeneously.
