Definitions

  • the invention relates to an ink or ink pen with a front part that comes into contact with the writing pad and a front part, a writing fluid cartridge, the interior of which contains the writing fluid is sealed before startup and is in operation in connection with the front part, and with one Compensation system, which is arranged in a housing having a front opening for the passage of the front part and which, in operation, has one end in communication with the interior of the writing fluid cartridge and the other end in communication with the ambient air.
  • a ventilation cartridge is attached to the tubular part of the cartridge carrying the writing tip.
  • the ventilation element consisting of a wound film covers a transverse opening of the tubular part of the ink cartridge and thus establishes the connection between the ink chamber and the pressure compensation element.
  • the writing fluid cartridge can be pulled backwards from the ventilation cartridge, so that it can be replaced by inserting a new writing fluid cartridge.
  • a new cartridge must be closed with a cap in the known device in order to prevent leakage or drying out.
  • the cover cap must seal the ventilation opening of the cartridge to prevent leakage.
  • the cartridge with the front part permanently attached to it can be removed from a storage position in which the interior of the part with it connected writing liquid cartridge is sealed, be moved into an operating position in which the rear end of the front part has destroyed the seal of the interior. In this way, the connection between the interior of the writing fluid cartridge and the writing tip is established. If the slat body has a continuous tube part for receiving the front part, there may be an opening in the wall of the tube part, which is in connection with one end of the compensation system.
  • a positioning arrangement for the axial securing of the front part in the compensation system can be provided in such a construction.
  • This can have a projection which is formed, for example, on the front part and which cooperates with an axial slot which is open at one end and has a transverse engagement region at its closed end.
  • the projection can be inserted into the open end of the axial slot and, in the end position of the front part that has been reached, can be displaced by a rotational movement into the engagement region, in which it is supported against axial movements.
  • an opening device can be provided on the compensation system, which, when the front part is inserted into the compensation system, establishes the connection between the latter and the interior of the writing fluid cartridge. In this case, the connection is not made via the interior of the front part.
  • the opening device can consist of a pipe section protruding towards the rear via the compensation system, which, in order to establish the connection with the interior of the writing liquid cartridge, destroys the sealing that seals it.
  • the tube recorder shown in FIGS. 1 and 2 has a front part consisting of a tube section 1, a transition section 2 fastened in its front end and one in the front At the end of the transition section 2, the usual writing tubes 3 are attached.
  • a falling weight body 4 which is pressed forward by a spring 6, but can be moved axially back and forth to a limited extent.
  • a cleaning wire 5 extending into the writing tube 3 is fastened in the front end of the drop weight body 4.
  • sawtooth-shaped projections 7 are formed, which are in engagement with corresponding depressions in the neck section of a writing liquid cartridge 10.
  • the sawtooth-shaped projections 7 of the tube section 1 and the corresponding depressions in the neck section of the writing fluid cartridge 10 connect the front part and the writing fluid cartridge 10 inseparably, i.e. the user cannot pull the pipe section 1 out of the neck section of the writing liquid cartridge 10.
  • an annular rib 8 provided behind the sawtooth-shaped projections 7 and formed on the outer surface of the tube section 1 engages with an annular groove 14 in the neck portion of the writing fluid cartridge 10.
  • the rear end of the tube section 1 is spaced from a seal 12, which seals the outlet opening of the interior 11 of the writing fluid cartridge 10 in this state.
  • the front part is inserted through a lamellar body 20, which has a substantially continuous tube part 21 and on the outside of which are formed by the lamellae annular compensation channels 22 which are connected to one another in the usual manner, the front end of the compensation chambers is formed by an axial channel 23 and the rear end through the connection to the interior of the tube section 1 of the front part via a transverse bore 9.
  • a distributor capillary Via a distributor capillary, the one emerging through the transverse bore 9 Writing fluid supplied to the individual slats.
  • the lamellar body 20 is firmly seated in a housing 30 which has at its front end a passage opening through which the transition section 2 of the front part carrying the writing tube 3 extends.
  • the user For axially positioning the front part, the user rotates the front part with respect to the lamellar body 20 such that the projection 29 comes out of the area of the axial slot 24 and is axially secured in both directions by the boundary walls of the engagement area 25.
  • the user pushes the writing fluid cartridge 10 forward, so that the annular rib 8 of the tube section 1 is pressed out of the annular groove 14 in the neck portion of the writing fluid cartridge 10 and enters the annular groove behind it, as can be seen in FIG. 1.
  • the user pulls the writing liquid cartridge 10 including the front part back out of the lamellar body 20 and inserts a new unit consisting of the front part and writing liquid cartridge in the manner described, after usually previously compensation system to be used again has been carefully cleaned.
  • the writing instrument has the shape of an ink ballpoint pen which has a ball 103 serving as a writing tip at the front end of its front part 101.
  • the tubular front part 101 is formed in one piece with the ink cartridge 110, the interior 111 of which seals in the storage position by means of a membrane 112 against the rear end of the front part 101 extending from the front wall of the ink cartridge 110.
  • the lamella body 120 forming the compensation system has conventional compensation chambers 122 and is delimited at the front end by an annular body 126 and at the rear end by an annular body 127, between which a tubular part 121 extends.
  • the lamellar body 120 is firmly seated in a housing 130 which has a front opening 132 which is connected to the compensation system via an indicated axial channel 131 in the front ring body 126 of the lamellar body 120.
  • a tube section 128 projecting to the rear is formed, the rear end of which is chamfered to form a type of cutting edge.
  • the front part 101 is inserted into the tubular part 121 of the lamellar body 120, but the writing tip 103 is still inside the housing 130 and the interior 111 of the ink cartridge 110 is still sealed by the membrane 112.
  • the unit comprising the front part 101 and the ink cartridge 110 in the housing 130 is pushed forward from the position according to FIG. 3 into the position according to FIG.
  • the pipe section 128 breaks through one of the predetermined breaking points formed by depressions 113 in the front wall of the ink cartridge 110 and releases the membrane 112 from its sealing position, so that writing fluid can enter the rear end of the front part 101 and reach the writing tip 103.
  • a connection from the interior 110 to the compensation system 120 is established via the pipe section 128.
