Definitions

  • the invention relates to a method for producing a large amount of ballpoint refills, the paste column is constantly acted upon by gas pressure.
  • a known method consists in bringing two substances which react with one another with gas separation onto the rear end of the paste column, the gas-separating reaction then starting after the paste tube has been completely closed. This process is cumbersome, expensive and inaccurate.
  • Another known method is to insert a sealed, gas-containing capsule into the rear end of the paste tube and to provide a sealing plug provided with a needle, the user having to pierce the gas capsule by pressing the plug when the lead is used, in order to build up the gas pressure.
  • This method is also imprecise and relatively complex, with the fact that the user still has to manipulate the mine.
  • the invention has for its object to provide a method for producing a large amount of ballpoint refills, the paste column is constantly pressurized by gas pressure, which ensures the generation and maintenance of the same gas pressure in all mines in a simple manner, and even in mass production a uniform Quality guaranteed.
  • a non-return valve with a passage direction into the interior of the paste tube is first installed at the rear end of each paste tube at a distance from the end of the paste column and then the leads as a whole are introduced into a container in which a gas pressure is generated that corresponds to the desired gas pressure in the mine, and that the mines are then removed from the container after the pressure has been released.
  • the method according to the invention has the advantage that when applying the gas pressure there is no need to take any structural details of the mine into account, and that neither chemical means nor mechanical measures or a complicated ultrasound device need to be used. It is sufficient to place a large quantity of the finished ballpoint pen refills in a pressure container and to apply the pressure desired in the refill, so that a corresponding pressure in the air space between the paste column and the valve body is established via the valve in all the mines in the pressure container which is then retained when the ballpoint pen refills are removed from the pressure container.
  • the ballpoint pen refill contains a paste tube 1 which is closed on its front side with the spherical writing tip 2 and on its rear side with a stopper 3.
  • the writing paste 8 is filled into the paste tube in the required amount and a valve plug is then inserted into the paste tube at a distance from the paste column.
  • the valve plug contains a section 4 facing the outer end of the paste tube, the outside diameter of which corresponds approximately to the inside diameter of the paste tube, so that the valve plug can be fastened in a sealed manner in the paste tube.
  • a bore 5 runs in the axial direction of the valve plug, which extends from the outer end of section 4 to section 9 and ends therein as a blind bore.
  • a bore 10 runs in the radial direction through the section 9, which is connected to the axial bore 5 and together with this forms the inlet channel for the gas into the space 7 above the paste column 8.
  • an elastic sealing sleeve is tightly applied, which closes the bore 10 and thus allows gas to enter the space 7, but prevents backflow.
  • valve plug including the sealing sleeve, is inserted and fastened into the paste tube as a prefabricated element, whereupon the end plug 3, which is hollow, is attached, so that the gas can reach the valve plug unhindered.
  • the application of the desired gas pressure to the room 7 takes place in that the finished ballpoint pen refill is simultaneously entered into a container together with a large number of other refills, in which gas is compressed to a pressure that corresponds to the pressure that also exists in the room 7 Mine is desired.
  • the pressure in space 7 then adjusts to the pressure prevailing in the pressure vessel, which pressure is also maintained in space 7 when the pressure vessel is depressurized again.
