Definitions

  • the invention relates to a refillable writing, painting or drawing device with a housing, a storage space for writing fluid, which contains a capillary storage body, and with an application tip detachably attached to the housing, which is connected to the storage body in the storage space via a capillary liquid conductor.
  • the tip of the application generally consists of a wick made of porous, often fibrous material, which wears out during use and therefore has a relatively short lifespan. Accordingly, it has since been dispensed with in such devices to provide special facilities to enable a refilling of writing fluid. If the supply of writing fluid was exhausted, the device had to be thrown away and replaced with a new one.
  • a refill container is known from DE 40 27 751 C2, with which the storage space can be filled again with writing fluid via a ventilation duct adjacent to the tip of the application.
  • this refill container requires a certain arrangement and size of the ventilation duct.
  • Another disadvantage is that the tip is not renewed, so the refill can generally only be repeated a few times until the tip is finally worn.
  • a refillable writing instrument which, for filling liquid application medium, has a closure body which can be at least partially removed from the shaft end opposite in the application tip and which closes a filling opening.
  • a renewal of the order peak is not envisaged here either.
  • the invention has for its object to provide a writing, painting or drawing device of the type mentioned, which is easily refillable and enables a renewal of the order peak.
  • this object is achieved in that the application tip is removably arranged in a filling opening for writing liquid and in that an air channel is formed in the storage space along the capillary storage body and is connected to the filling opening via a connecting channel opening laterally into the filling opening.
  • the device according to the invention has the advantage that a refilling of writing fluid and the replacement of the tip in connection with one another are possible in a simple manner.
  • the filler opening is closed by the tip of the application, so that additional closable openings are unnecessary and the manufacturing effort remains small.
  • an advantageously large filling opening is available after the tip of the application has been removed, and the design and arrangement of the air channel allow the writing fluid to penetrate the storage body quickly and in a targeted manner, since the length of the ring channel gives the capillary storage body sufficient time to absorb the writing fluid without the ventilation channels being closed due to the short-term excess supply of writing fluid.
  • the filling opening can have a size such that the refilling of writing fluid is possible with a spout attached to the refill container, which can be inserted into the filling opening, so that contamination of the outer surface of the writing instrument when refilling writing fluid is avoided.
  • connecting channel is formed by a collar which is coaxial with the filling opening and which projects into the storage space and bears against the storage body and which has an especially slot-shaped side on its side opposite the air channel Opening is broken.
  • the edge of the collar engages in a recess in the storage body.
  • the application tip has a sleeve which can be fastened non-positively or positively in the fill opening of the housing and which has projections on a section projecting outward from the fill opening for attaching a tool acting in the axial direction or rotating on the sleeve .
  • the sleeve forms a socket for the tip of the order and can be designed so that, on the one hand, a good fit in the fill opening and, on the other hand, easy assembly and disassembly can be achieved.
  • the outwardly projecting section of the sleeve has an annular collar of larger diameter, which is located at a distance from the filling end of the housing that is suitable for the engagement of a tool.
  • the sleeve can have a longitudinal groove on its outside or inside.
  • the tool for pulling out the application tip can be a separate tool or can be attached to a part detachably connected to the housing, in particular to the cap for covering the application tip. In the latter case, the appropriate tool is always available if the tip of the application is to be removed from the fill opening for replacement or refilling.
  • the tool can be designed as a fork which can be inserted into the space between the collar and the housing.
  • the fork can, according to the invention, be formed by two jaws arranged on the bottom of the cap for covering the application tip, the mutual spacing of which corresponds to the diameter of the filling end of the housing and which have mutually parallel ribs on their mutually facing sides, which extend into the space between the annular collar Sleeve and the housing can be used.
  • the writing instrument shown in the drawing consists of an essentially cylindrical housing 1, which encloses a storage space 2 with a capillary storage body 3 for receiving writing fluid.
  • One end of the housing 1 is provided with a tapered neck 4, which has a filling opening 5, into which an application tip 6 is inserted.
  • the application tip 6 consists of a capillary wick 7 which is held in a socket formed by a sleeve 8.
  • the ends of the wick 7 protrude from the sleeve 8 and are provided with a conical tip 9 or 10.
  • the tip 9 is used to apply the writing fluid when writing.
  • the tip 10 protrudes into the storage body 3 and enters into a capillary connection in such a way that the wick 7 is adequately supplied with writing fluid.
  • the inner end of the sleeve 8 engaging in the filling opening 5 is provided with slots 11 and on the outside with a circumferential bead 12, the outer diameter of which is larger than the outer diameter of the sleeve 8.
  • the filling opening 5 in the housing 1 has an outer section 13 whose inside diameter corresponds to the outside diameter of the sleeve 8. Section 13 is adjoined by an inwardly tapering section 14 which merges into a cylindrical section 15 of larger diameter.
  • the sleeve 8 engages with its bead 12 in the section 15, which bears against the wall of the filling opening 5 with radial prestress.
  • the filling opening 5 and the sleeve 8 an easily assembled snap-in connection is created, which ensures a play-free, but detachable in the axial direction, holder of the application tip 6 in the housing 1.
  • the outer end of the sleeve 8 protruding from the filling opening 5 is provided with a collar 16 which has a flat contact surface 17 on its side facing the neck 4. Between the contact surface 17 and the neck 4, an annular gap 18 is provided, which is used for inserting a release tool.
  • the section 15 of the filling opening 5 is extended axially inwards by a cylindrical collar 19, the edge of the collar 19 engaging in a correspondingly shaped recess in the storage body 3.
  • the collar 19 is pierced at one point by an axial slot 20.
  • An annular channel 21 is separated from the filling opening 5 by the collar 19 and is only connected to the filling opening 5 via the slot 20.
  • Connected to the ring channel 21 on the side opposite the slot 20 is an air channel 22 formed by a groove in the inner wall of the housing 1, which extends along the storage body 3 and ventilates or ventilates it as required.
  • the air channel 22 communicates with the atmosphere via the ring channel 21, the slot 20, the filling opening 5 and a longitudinal groove (not visible in the drawing) in the outer surface of the sleeve 8.
  • the applicator tip 6 can be covered with a cap 23 to prevent drying out when not in use, which tightly engages around the neck 4 from the outside with an inner cap 24.
  • a fork-like tool 26 is attached on the outside of the bottom 25 of the cap 23 .
  • the tool 26 has two jaws 28 which are separated from one another by a central recess 27 and which on their mutually facing sides carry axially parallel ribs 29 which lie opposite one another. After removal of the cap 23, the tool 26 can be plugged onto the neck 4 in such a way that the ribs 29 engage in the gap 18 and bear against the contact surface 17 with one side surface.
  • the application tip 6 can be pulled out of the filling opening 5, as shown in FIG.
  • the holding force caused by the bead 12 is overcome and the slotted area of the sleeve 8 is radially elastically compressed, while the bead 12 passes through the sections 14 and 13 of the filling opening 5.
  • the storage space 2 can be refilled with writing liquid with the aid of a refill container 31.
  • a rapid penetration of the writing fluid into the storage body 3 is achieved here by the formation of the ring channel 21 and the air channel 22.
  • the annular channel prevents the writing liquid from reaching the air channel 22 and thereby obstructing the air outlet, because the enclosed air retains the writing liquid filled into the filling opening 5 at the slot 20 and occurs in the form of air bubbles at the slot after the required pressure drop has been reached 20 into the filling opening 5. This ensures a rapid absorption of the writing fluid by the storage body 3.
  • the filler opening 5 is preferably closed again with a new applicator tip 6 by pushing it into the filler opening 5 up to its end position, which is limited by a stop (not shown), in which the bead 12 is located in the section 15 .
