Definitions

  • the invention relates to a writing instrument with a front part carrying a writing tip in its front end, which has an inner bore extending rearward from a connection with the writing tip, and with a writing liquid container which is sealed in a storage position from the inner bore and in one Operating position is in flow connection with the inner bore.
  • a writing instrument of the type mentioned is designed in accordance with the invention in such a way that a through hole located at a distance from the longitudinal axis of the inner bore is provided in the wall of the front part and an outlet opening is provided in the writing liquid container and that the through hole and outlet opening are in communication with one another in the operating position and are sealed against each other in the storage position.
  • the writing liquid container is preferably attached to the front part and the through hole is formed in the peripheral wall of the front part.
  • the sealing of the writing fluid container in the storage position takes place solely through its orientation or the position of its outlet opening with respect to the front part or the position of the through-hole in this front part, so that the operating position is obtained when the writing liquid container and front part are displaced relative to one another be that the through hole and the outlet opening are in connection with each other.
  • there is no pressure increase in the writing fluid container and there is no need for a wall or the like. of the writing fluid container to be destroyed.
  • the writing fluid container and the front part can be rotated relative to one another for movement from the storage position into the operating position.
  • an axial relative movement of the writing fluid container and front part which is easier to accidentally carry out by the user, is avoided, so that an erroneous movement into the operating position can practically not occur.
  • the writing fluid container has in the inner surface of its section which is plugged onto the front part a depression which forms a pressure compensation chamber and which at its front end communicates with the ambient air and at least in the operating position at its rear end axially in front of the through bore with the inner bore stands.
  • the writing liquid container and the pressure compensation chamber thus form a structural unit, so that when the writing liquid container is replaced, it is the same the pressure compensation chamber, which is particularly susceptible to contamination, is replaced at an early stage.
  • the writing instrument shown in the form of a tube recorder has a front part 1, in the front end of which a writing tip in the form of a writing tube 2 is inserted.
  • this writing tube 2 extends in a known manner a cleaning wire 4, which is inserted into the front end of a falling weight body 5, which is located in an inner bore in the front part 1 and can be moved back and forth to a limited extent.
  • a writing liquid container 7 is fitted from behind, which in its clamping engagement with the outer surface of the front part 1 carries a helical pressure compensation chamber 9 which is delimited inwards by the outer peripheral wall of the front part 1.
  • the pressure compensation chamber 9 is connected in a conventional manner, not shown, at its front end to the ambient air.
  • In the rear end of the front part there is a transverse bore 10, which connects the pressure compensation chamber 9 with the inner bore 3 of the front part 1.
  • the writing liquid container 7 has a writing liquid supply located behind the rear end of the front part space that merges into an axially extending outlet opening 8.
  • the axially front end of this outlet opening 8 lies axially approximately at the same height as a through hole 6 provided in the peripheral wall of the front part 1, which is provided between the transverse bore 10 and the outer rear end of the front part 1.
  • the outlet opening 8 and the through-hole 6 are offset from one another in the circumferential direction, so that the through-hole 6 is sealed by the inner circumferential surface of the adjacent area of the writing liquid container 7.
  • the writing liquid storage space of the writing liquid container 7 and the outlet opening 8 are opposite the inner bore 3 of the front part 1 sealed. If the front part 1 and the writing liquid container 7 are rotated relative to one another from the position according to FIGS. 1 and 2 so that they come into the position according to FIG. 3, there is a flow connection from the outlet opening 8 via the through bore 6 to the inner bore 3 of the front part 1, so that writing liquid flows out the writing liquid container 7 can get into the inner bore 1 and thus to the writing tube 2.
  • the inner bore 3 can of course also be sealed again with respect to the writing fluid reservoir of the writing fluid container 7 by a corresponding twisting movement.
