Definitions

  • the invention relates to a felt-tip pen with a housing in which a tampon made of absorbent material for storing its ink is arranged and to which a separate refill device is assigned, which has a chamber filled with ink.
  • Felt-tip pens of the above type are built in very different embodiments and are used, for example, for writing and drawing on pin boards in huge quantities. For ecological reasons, it is unsatisfactory for felt pens to go to waste as soon as their ink has been used up.
  • Refill devices have therefore been developed with which ink can be dripped from a relatively large-volume chamber into the housing of the felt-tip pen after a cover on the side of the felt-tip pen housing facing away from the writing tip has been removed.
  • a refill device designed as a pipette reference is made to DE-C-911 185.
  • An elastic ball is attached to the outside of the lid of a refill bottle and a tube is attached to the inside of the lid, which is immersed in the liquid of the refill bottle.
  • the invention is based on the problem of designing a felt-tip pen with a separate refill device in such a way that the refill can be carried out as simply as possible and without risk of contamination of the surroundings.
  • refilling without unscrewing or removing a cover of the felt-tip pen housing can be done in a very simple manner by piercing the area of the felt-tip pen housing intended for this purpose with the injection needle of the refill device, then the ink from the Refill device transferred to the felt tip pen and then simply pulls the injection needle out of the felt tip pen again.
  • the volume of the chamber corresponds to the maximum amount of ink to be held by the tampon due to its absorbency. This ensures that no larger amount of ink can be entered in the felt pen than is able to hold due to the size and absorbency of its tampon.
  • too much ink was very often filled into the felt-tip pen. When As a result of such overfilling, too much ink gets to the felt and drips out of the felt-tip pen, which generally means that the user never refills a felt-tip pen again.
  • the felt pen can be made of an inexpensive and solid material if the area to be pierced by the injection needle is formed by an elastic insert in the housing of the felt pen.
  • the felt-tip pen is particularly simple to construct and refill if, according to another embodiment of the invention, the insert is provided in the upper end face of the housing.
  • Penetration of the insert by means of the injection needle can be facilitated if the insert has a prefabricated passage which is closed by the elasticity of its material.
  • the refill device is particularly simple and at the same time storage container for the liquid to be refilled in the felt-tip pen, if, according to another development of the invention, the chamber is provided on the outside and the injection needle on the inside on a lid of a refill bottle and the injection needle projects into the refill bottle when the lid is attached.
  • Such a refill device can be refilled in a simple manner, similar to a pipette of a dropper bottle, by squeezing its chamber and then sucking in liquid from the closed bottle, without there being any risk of contamination of the environment. Therefore, the refill device can be used at least as often until the refill bottle is empty. Furthermore, there is no risk of injury from the injection needle when storing the refill device.
  • the injection needle only just protrudes into the bottle neck of the refill bottle when the lid is in place.
  • a refill has several advantages. Since the injection needle is very short and does not protrude or hardly protrudes beyond the height of the edge of the lid, the risk of injury to the injection needle is very low even when handling the lid with the injection needle.
  • the refill bottle must be held overhead so that the end of the injection needle is immersed in the liquid. The result of this is that foam in the liquid floats far away from the needle on the liquid level then pointing to the bottom, so that no foam is sucked in with the needle.
  • the cover facilitates the centering of the injection needle on the housing of the felt-tip pen and fixes the chamber on the housing when refilling, if, according to another development of the innovation, the cross-section of the cover is designed to be placed on the housing of a felt-tip pen during the refilling process.
  • FIG. 1 shows a felt pen 1 in perspective, which has a cylindrical housing 2 with a cover 3.
  • a fiber tip 4 protrudes downward from the housing 2, which receives ink for writing from a tampon 5 soaked with ink and arranged within the housing 2.
  • An insert 6 made of an elastic material, preferably rubber, is arranged in the cover 3 of the housing 1.
  • a refill device 7, which essentially consists of a ball-like, elastic hollow body 8 with a chamber 9 and an injection needle 10, serves to refill the felt-tip pen 1.
  • the volume of this chamber 9 is dimensioned so that just the amount of ink that is needed to soak the tampon 5 can be present in it.
  • the insert 15 is pierced with the injection needle 10 and then the ball-like body is pressed together, so that the ink comes from the chamber 9 into the felt-tip pen 1. Then you pull the refill 7 back again. Due to the elasticity of the insert 6, the hole in the insert 6 closes by itself as soon as the injection needle 10 comes out of it.
  • FIG. 2 shows a refill bottle 12 which tapers uniformly in cross-section from a base 16 to its bottle neck 13.
  • a lid 11 can be screwed onto the bottle neck 13 from above, for which purpose the lid 11 has an internal thread 17 and the bottle neck 13 has an external thread 18.
  • the refill bottle 12 shown is initially held upside down when the lid 11 is screwed on. Then, with two fingers, the chamber 9, which is designed as an elastic ball, is pressed together, as a result of which the air in it reaches the refill bottle 12. When the chamber 9 is released, it returns to its original shape and soaks up liquid.
  • the cap 11 is unscrewed from the refill bottle 12 and its injection needle 10 is pierced through the area provided in the upper end face of the felt pen 1 until the cap 11 is placed on the housing 2 of the felt pen 1.
  • the injection needle 10 is dimensioned in terms of its length such that it then only reaches a space above the tampon 5 of the felt-tip pen 1. This makes it possible to quickly transfer the liquid present in it into the felt-tip pen 1 by pressing on the chamber 9 designed as an elastic ball, since no high flow resistance can be overcome.
  • the volume of the chamber 9 can be dimensioned so that it corresponds exactly to the amount of liquid required for a conventional felt-tip pen. For thicker felt pens, the refill process must be carried out twice. Regardless of the size of the chamber 9, however, the refill bottle 12 according to the invention enables precise dosing of the required refill volume, which is particularly important if a felt-tip pen is used for refilling is not completely empty, so that an amount of liquid that cannot be determined exactly must be refilled.
