Definitions

  • the present invention refers to a point for ballpoint pens.
  • points of a well-known kind comprise a brass tip provided with a ball, and a conical body made of plastic material, which presents a tapering portion connected to the tip, and a cylindrical engaging portion which is suitable for being connected to the ink cartridge, as well as to the tube of the ballpoint pen.
  • the points of the kind described above require at least two assembly phases: a first phase in which the cartridge is engaged inside the cylindrical engaging portion, and a second phase in which the tube is engaged externally to the cylindrical engaging portion itself.
  • the aim of the present invention is to produce a point for ballpoint pens, which will permit a reduction in the number of assembly phases as well as a reduction in the number of components of the ballpoint pens themselves.
  • a point for ballpoint pens comprising a tip, and a main body presenting an outer portion which is connected to the tip, and an engaging portion which is suitable for being connected to a tube of the ballpoint pen; the point being characterised by the fact of comprising an ink cartridge which forms a single body with the main body.
  • the number 1 refers to a point for ballpoint pens 2 in its entirety.
  • the point 1 presents a longitudinal axis A, and comprises a brass tip 3 provided with a ball 4, and a main body 5, which is provided with an engaging portion 7 suitable for being connected to a tube 8 of the pen 2, and with a conical portion 6 which is interposed between the portion 7 and the tip 3, and which is arranged outside the tube 8.
  • the point 1 also comprises a cartridge 10, which is suitable for containing ink 11, and which forms a single body with the main body 5 being produced together with the main body 5 itself by means of a procedure of injection moulding thermoplastic material.
  • the cartridge 10 comprises a cylindrical body 12 which extends through the engaging portion 7, and presents an inner cylindrical cavity 13 which defines, in part, a reservoir 14 for the ink 11.
  • the reservoir 14 is further defined by an additional cylindrical cavity 15, which extends through the writing portion 6 as far as the tip 3 and which is connected to the cavity 13.
  • the engaging portion 7 is defined by a flexible cylindrical body 71 which is arranged around the cylindrical body 12 of the cartridge 10 as far as a length which is less than a length of the body 12 itself, and may be engaged inside the tube 8.
  • the body 71 is elastic enough to be able to deform when the tube 8 is introduced and to be able to exert an elastic return action on the tube 8 itself in order to avoid the accidental separation of the tube 8 from the point 1.
