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.
  • the receiving space has an intermediate wall with a through hole, which divides the receiving space into a storage space and a working space.
  • At least one closure and / or mixing body which cooperates with a seat formed in the region of the through-hole, can be arranged in the storage space.
  • a closure and / or mixing body can be arranged in the working space, which cooperates with a seat formed in the region of the through-hole.
  • a valve device is arranged, which comprises a valve housing with a valve seat and a valve closure body acted upon by a return spring having.
  • the valve closure body is movably mounted in the valve housing cooperating with the valve seat. It is provided a writing tip, which is connectable to the working space.
  • 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.
  • the inflow opening of the valve housing can be closed by a ball. This ball forms a closure and / or mixing body. It lies in the writing position, in which the writing tip is directed downwards, in each case in the inflow opening and closes it.
  • the writing instrument In order to allow an inflow of medium into the valve housing, the writing instrument must be shaken, so that the ball comes out of its blocking position from the inlet opening. During the shaking movement, the ball simultaneously acts as a mixing body for the medium in the receiving space outside the valve housing.
  • the disadvantage is that in each case a shaking movement is required to move the ball from the flow hole, so that an inflow of ink into the working space is made possible. This interferes with handling when working with the writing instrument for a long time.
  • 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 prevent mixing of binder and dye.
  • the valve device is opened so that a mixture of binder and dye takes place in the region above the writing tip. The user can then write with colored ink.

  • no closure and / or mixing body is provided which has a seat in the region of a through-hole having.
  • the receiving space is in the embodiment in US 2004/0240925 A1 is separated exclusively by the valve seat of the valve housing and is actuated by the designed as a ram valve closure body so that the valve seat is open when writing.
  • the open position of the valve in the writing position is required to realize the mixture of the dye with the binder, which must be due to the separate arrangement of binder and dye for writing.
  • 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.
  • the 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.
  • no closure and / or mixing body is provided in the storage space or in the working space, which cooperates with a seat in the region of the through hole of the intermediate wall.
  • the closure of the through hole in the intermediate wall is realized in this known construction exclusively by the surface tension of the medium received in the storage space.

  • the writing tip 40 is in the front end of the sleeve 12 off and inserted. It is guided by the front sleeve-shaped guide end 31 f of the front valve housing 31. This guide of the writing tip 40 in the front valve housing 31 is carried out to form a calibrated annular cross-section guide slot 31 fs.
  • the annular guide slot 31fs in the sleeve-shaped guide end 31f has an axial length which corresponds to approximately one third of the axial length of the writing tip 40 formed as a cylinder body.
  • the calibration is performed in such a way that the inside width of this annular slit 31fs permits a ventilation of the receiving space 11, but a flowing exit of the medium does not take place through the annular guide slit 31fs.
  • the outer wall of the guide pin 40 is only wetted by the medium.
  • the writing tip 40 is formed of porous material. It is supplied with the medium by the medium from the working chamber 11 a, ie from the front end of the valve housing, capillary in the writing tip 40 progresses to the free end of the writing tip 40. About the calibrated guide slot, the outside of the writing tip 40 with the Medium so just wetted. The bulk of the media is provided at the writing tip 40 via the capillary mass transport through the porous writing tip.

  • the film skin is protected from unintentional damage prior to initial start-up.
  • the user can also recognize whether the medium in the storage space 11v is in a writable state. If the device is stored for long periods in non-use position, the color pigments settle on one side in the storage room. Incident light is then absorbed to varying degrees in the slot-shaped transparent areas. The medium, seen through the two slit-shaped transparent areas, then appears differently colored to the viewer. To produce a uniform mixing, the user can then shake the device until the color pigments are stirred up and again evenly distributed in the binder. He can observe this mixing process and the state of mixing through the transparent slots. As soon as the uniform mixing is achieved, the medium appears as the same color in the two slit-shaped transparent areas.

This can be done by the user in that the writing tip 40 is fully retracted and is moved with the plunger end of the valve closure body of the piston-shaped mixing body to the rear wall to the intermediate wall. In this case, the closure body engages with its pointed end in the through hole 21 and pierces the film skin 20fh.
