Definitions

  • the present invention relates to devices for writing, marking and / or painting with a liquid medium, in particular devices for applying highly pigmented inks, referred to in practice as valve markers.
  • a prior art which are devices for writing, painting or marking. They have a receiving housing, with a receiving space for the medium.
  • a valve device In the receiving space, a valve device is arranged, which has a valve housing with valve seat and a valve spring body acted upon by a return spring mounted in the valve housing cooperating with the valve seat.
  • a writing tip is provided, which is connectable by the valve means with the working space and is mounted relative to the receiving housing and retractable under actuation of the valve closure body.
  • a sponge is arranged as a buffer between the valve device and the writing tip.
  • the valve closure member is designed as a piston which is guided displaceably in the valve housing and thereby largely fills the entire cross section of the valve housing. In the valve housing remain relatively narrow angled annular spaces that receive the return spring and the medium.
  • a disadvantage of this prior art writing instrument is that sometimes too much or too little ink is available at the writing tip during writing.
  • this writing instrument is only suitable for use with aqueous or alcohol based dye inks. If heavily pigmented inks are used, d. H. Inks that consist of a binder in which heavy color pigments are distributed, it may lead to sedimentation of the color pigments in the valve areas at extended disuse. Due to the narrow receiving spaces in the valve housing, the color pigments can practically no longer be stirred up. The writing tip may become slippery due to the accumulation of color pigments, thereby obstructing or clogging the flow of ink. Further, also because of the buffer used in this writing instrument which works with a sponge or the like, the use of highly pigmented inks is not possible or at least very problematic because in such buffers primarily the binder and not the pigments are taken up.
  • valve marker writing instrument In the US 2004/0240925 A1 is another described as a valve marker writing instrument described which is intended in particular for writing with colored ink.
  • the binder and the dye are stored in separate spaces, which are separated in the non-use position of the writing instrument via a closed valve means to a mixing of binder and dye to prevent.
  • the valve device is opened so that a mixture of binder and dye takes place in an area above the writing tip. The user can then write with colored ink.
  • This separation of the arrangement of dye and binder must be present before commissioning.
  • the disadvantage is that the valve opens by already slight movement of the writing tip and the inflow of the binder takes place to the dye and the ink can then escape.
  • the ink is stored in two separate rooms, in a storage room and in a working space, which are separated by an intermediate wall with a through hole.
  • the separation takes place in that the ink is held in the area of the through hole in the storage space due to its surface tension.
  • the separation can be canceled by engaging the plunger of the valve closure member by pushing the writing tip into the through hole so far that the liquid surface is pierced and the ink in the upper portion of the working space formed between the intermediate wall and the valve seat, passes.
  • a memory is formed with an ink absorption body, via which the writing tip is supplied with ink.
  • valve seat By pushing in the writing tip, the valve seat is opened to supply the ink to the lower working space.
  • the valve device is closed, so that only the ink present in the lower working space in the ink absorption body is available during writing.
  • a disadvantage of this design of the writing instrument is that the geometric configuration of the through hole in conjunction with the arrangement of the plunger must be specially adapted to the ink used and its surface tension and also the function is highly temperature-dependent.
  • the present invention has for its object to provide a valve marker, which is ensured in a structurally simple way that prior to initial commissioning, the ink remains in the reservoir.
  • the valve marker should be suitable for the use of different inks.

  • the closure element may be a foil element or else a slider or folding element or the like. It is essential that the closure element is arranged in the region of the through-hole before the start-up and is preferably fixed in the region of the through-hole.
  • the fixation can also be realized on the intermediate wall outside the through-hole. The fixation is cohesively and / or positively designed.
  • closure element is held by this fixation before commissioning safely in the region of the through hole to lock the through hole, so that the medium present in the storage space can not pass into the working space.
  • cohesive fixing can be provided that the closure element is welded or glued in the edge region of the through hole.
  • the closure element may also be formed integrally with the intermediate wall in which the through-hole is arranged, e.g. as a plastic film, preferably of the same material as the intermediate wall.
  • a positive fixing of the closure element can also take place in that the closure element is arranged in the manner of a press fit in the through hole or behind cross-section in the region of the through hole.
  • the closure element is moved away before the first use of the device and / or destroyed.
  • the ram end can be specially designed, for example with a pointed or hook-shaped end. It is essential that the end of the plunger is adapted to act upon its operation, preferably by inserting the writing tip, the closure element accordingly, so that it is moved away and / or destroyed.
  • cohesively fixed closure elements is preferably in question that the end of the ram destroys the closure element.
  • the positive fixing of the closure element is preferably a way moving through the ram end in question.
  • the destruction of the closure element can preferably take place in that an opening is introduced through the end of the plunger.
  • the closure element may optionally have a predetermined breaking point for this purpose in special embodiments. If the closure element is designed as a film element, it can preferably be provided that the plunger end punctures the film element. In particularly preferred embodiments, the closure element is designed as a film skin which can be pierced by the end of the tappet. The closure element is preferably formed as a thin film in this case.

  • the wall of the receiving space may be at least partially transparent or translucent, optionally formed in the form of viewing windows, to determine whether the relevant section of the receiving space is filled with medium.
  • closure element is arranged on the working space facing side of the intermediate wall. This means that the closure element is arranged on the side of the through-hole which faces away from the storage space and is arranged in the working space.
