Definitions

  • the invention relates to a tube recorder tip with a front part carrying a writing tube at its front end, onto which a writing liquid cartridge is placed from behind with its front section, which has a closure part to be released by the front part when the front part is inserted into the operating position in the writing liquid cartridge , and whose front end region has a reduced, elastically expandable opening cross section, which in the operating position engages behind a projection region formed on the front part, the outer diameter of the front part in the region in front of the projection region being smaller than the maximum diameter of the opening cross section in the operating position of the front part.
  • the expandable opening cross section of the writing fluid cartridge is in the operating position in a practically inseparable connection with the front part, ie the expandable opening cross section engages behind the projection area of the front part, so that the user no longer has the two elements can separate. This is to ensure that the user does not produce an unsuitable combination of writing fluid cartridge and front part or connects a front part after the writing fluid from the writing fluid cartridge has been used to a new writing fluid cartridge if the front part is designed such that it consumes the writing fluid from the associated writing fluid cartridge is usually no longer functional or sufficiently accurate.
  • a writing instrument tip (FR-PS 1 048 243), in which an extension is provided either in the form of an approximately lenticular head or in the form of an annular rib at the rear end of the front part, which when pressing the rear end of the front part in the front end of the writing fluid cartridge and the displacement of the spherical closure part taking place in the interior of the writing fluid cartridge comes into engagement with a correspondingly shaped, ring-shaped edge region of the writing fluid cartridge, and is thus held in this against pulling out, while the insertion movement by applying a radially over the front Edge of the writing fluid cartridge protruding paragraph is limited to the front edge of the writing fluid cartridge.
  • the user can pull the two parts apart again by hand due to the shape of the projection area of the front part and the elasticity of the material of the writing liquid cartridge, but there is a risk that such a separation is accidentally made. However, even if the separation is deliberate, there may be sudden movement of the two parts when the parts are pulled apart, and the remaining writing fluid may be splashed.
  • a tube pen tip of the type mentioned at the outset is designed in such a way that an auxiliary tool can be placed on the front part from the front and can be brought into widening engagement with the expandable opening cross section of the writing liquid cartridge.
  • an auxiliary tool can thus be placed on the front part from the front in order to expand the opening cross section of the writing fluid cartridge in a controlled manner, so that the widened opening cross section either under the direct influence of the auxiliary tool or by a slight sliding movement to be carried out by the user to the rear passes over the projection area of the front part. Therefore, the separation movement is smooth and not jerky and there is no risk of splashing of writing fluid.
  • slots that are open to the front and parallel to the axis can be present in the expandable cross-sectional area.
  • An external thread for screwing on the auxiliary tool can be present in the section of the front part lying in front of the projection area and partially covered by the expandable cross section, so that the auxiliary tool to be screwed on generates a sufficient force on the one hand for widening the opening cross section and on the other hand can be brought into engagement with it in an easily controllable manner can.
  • the rear side of the protruding area can follow the displacement of the writing fluid cartridge on the front part Form the front stop for the contact of a surface area of the writing fluid cartridge.
  • the writing fluid cartridge can be composed of several parts. For example, it can have an inner cartridge part which forms the writing fluid storage space, and on the outside of its front region it can have a groove for forming a pressure compensation chamber.
  • the auxiliary tool can represent a separate component. However, it can also be formed, for example, at the rear end of a cover cap which can be placed on the writing liquid cartridge from the front.
  • the tube recorder shown can have a structure in the region of the cover cap 15, which is represented by the holder shaft 1 and the section (not shown in section), essentially corresponding to the tube recorder according to FIGS. 3 and 4 of DE-PS 37 09 918 (C1), but with the front part in the operating state is not in barb-shaped engagement with an area of the writing fluid cartridge that is adjacent to the closure member in its sealing position.
  • an axially limited back and forth movable weight body 4 is provided in the inner bore 3 of the front part 2, its in the front end attached cleaning wire 5 extends in the usual manner into the writing tube 6 attached to the front end of the front part 2.
  • the rear portion of the front part 2 extends sealingly into the front area of the writing fluid cartridge 10, so that there is formed by the helical recess 11 provided in the inner wall of the writing fluid cartridge 10, a pressure equalization chamber which is used in a conventional but not shown manner in connection with the There is writing liquid storage space of the writing liquid cartridge 10, which was connected to the rear end of the front part 2 and thus also to the rear end of the inner bore 3 by inserting the front part 2 into the writing liquid cartridge 10 to the depth shown by loosening the closure part, also not shown.
  • hook-shaped projections 12 are formed by axial incisions (FIG. 2), the hook sections of which protrude radially inwards and which can be displaced elastically radially outwards. Therefore, if the front part 2 is inserted into the writing fluid cartridge 10 from the front, the ring shoulder 8 of the front part 2 comes into contact with the front, somewhat obliquely radially inward regions of the hook-shaped projections 12 and presses them apart elastically until the ring shoulder 8 passes through the Has passed through hook areas and rests with its rear ring surface on a front end surface 13 of the writing fluid cartridge 10. In this position, the hook-shaped projections 12 can snap back elastically into the position shown and thus hold the front part 2 in an axially non-displaceable manner.
  • the section of the front part 2 which adjoins the ring shoulder 8 at the front has a smaller diameter than the inside width in the region of the hook sections of the projections 12 and has an external thread 7 which extends to the rear up to the ring shoulder 8.
  • a conventional cover cap 15 which has a clip 16 and into which a sealing insert 17 of conventional construction is inserted, is attached to the tube recorder shown from the front, and an elastic sealing element 18 is fastened in the bottom area thereof, which, when the sealing cap 15 is attached, the front end of the writing tube 6 seals tightly.
  • the cap 15 is screwed with its internal thread 19 onto the external thread 7 of the front part 2, the area of the front part 2 including the writing tube lying in front of the external thread 7 6 protrudes into the opening continuing through the internal thread 19 into the sealing cap 15.
  • the wedge surface 20 comes into the area between the internal thread 7 and the hook areas of the projections 12 and thereby elastically presses the projections 12 apart until the annular shoulder 8 comes free from the hook-shaped areas of the projections 12 and so the writing liquid cartridge 10 moves backwards from the front part 2 can be deducted.
