Definitions

• the invention relates to a filling device and a method for filling writing utensils, such as those e.g. are available under the name senator "Aqua Painter", cf. Operating instructions Aqua Painter, commercially available. "Writing” encompasses all types of application of a mark on a surface, such as painting, decorating, filling.
• a known writing instrument has a storage for the refillable writing material arranged in a housing, into which storage a wick-like part of the writing tip exposed at one end of the housing protrudes. At the other end of the housing, it is open for refilling and can be sealed with a separate cap
• the filling device according to the invention has a filling nozzle which can be inserted into the housing (claim 4).
• a metering cap which is adapted to the filler neck and is relatively movable relative to the latter is provided and remains on it for filling.
• the filler neck can be inserted sealingly into the end of the housing.
• the metering cap is preferably arranged to be relatively movable on the filler neck, but is captive (claim 4, claim 9).
• the housing When the dosing cap is moved into the closed position, the housing is also sealed off from the outside, so that no more liquid can escape outside, except as colored writing material, via the writing tip itself.
• the parts are firmly or captively connected to one another, so that the user does not have to take care that he does not lose a part, such as the closure cap, or that there is a risk of swallowing (small parts below a predetermined minimum size ).
• the nozzle has a sleeve-shaped section which has essentially the same diameter as the elongated device housing. On this section, the movable cap slides with its intermediate storage space (claim 12, claim 5).
• the filling paths are located as windows (claim 7) at least in sections laterally (to the side or radially) in order to reach the intermediate store (claim 15).
• An axially directed section of the filling path connects to the main memory in the device housing (claim 14).
• the "fill” concerns both the filling of the temporary storage and the filling of the main storage, which takes place in two time sections.
• the filling path or filling window can thus be understood to mean both the lateral and the axial, and also both sections of the filling device.
• a tapered section of the filler neck (claim 14) can directly adjoin it, preferably also be pressed slightly into it.
• the amount of liquid pre-metered after turning the writing instrument flows through the tapered section (the front section of the filler neck), directly into the fibrous material in which the colored writing liquid is stored. It makes sense venting in a different way than the one through which the liquid flows for filling or refilling.
• a ventilation opening is provided (claim 13, 15), which is not within the axial flow path, but is radially adjacent.
• a flow opening which may be circumferentially limited, is preferably located in a transition section between the tapered section and the outer end section of the filler neck facing the metering cap.
• the movable dosing cap or filler cap with its dosing volume as a buffer and the writing instrument with its holding volume as a main storage can also be understood to mean that an intermediate storage is held on at least two arms of the dosing cap oriented backwards, which is movably arranged on the dosing cap at the rear end of the writing instrument is.
• the metering volume can thus be moved relative to the writing instrument without being removed from the writing instrument or needing to be removed in order to enable filling through the windows formed between the axially extending arms.
• the metering or filling volume is relatively moved relative to the main storage, that is to say approached to or removed from it.

• the writing instrument shown in the figures has a sleeve-shaped housing 1, at one end 7 of which a writing tip 2 is sealingly inserted.
• the writing tip can be sealed (sealingly) by means of a closure cap 3 by pushing the cap onto a tapered front end 7 of the housing 1.
• a storage space 6 as the main storage, which can hold a supply of colored writing fluid.
• the reservoir 6 is provided with a fibrous filling 6a, which absorbs the liquid, stores dry or pasty color concentrate before the first filling and then also stores liquid writing material when the liquid (such as water) is filled in from the outside.
• the brand-new writing instrument can already contain a writing material in dissolved form (a colored writing material) in the main memory 6,6a.
• the memory 6a filled with fiber material is filled with moisture during the manufacturing process, is not dried and is inserted into the writing instrument in the moist state.
• the filling device is then placed on, as described later.
• This filling device at the rear end 8 of the writing instrument sleeve 1 can be used to refill liquid in order to refresh or renew the writing material if it has dried out too much due to either use or storage for too long.
• the rear end 8 of the housing 1 is axially open and receives a filler neck 4, which is inserted in this end in a sealing and permanent manner, with a plug-in section 15, as shown in FIGS. 5 to 7.
• the filler neck has two axial sections, a rearward oriented first axial section 4b and a forwardly oriented, radially retracted or tapered section 4a, which is provided with outer rings 15, in order to ensure a non-positive connection when inserted into the rear section 8 of the device housing 1 To achieve connection that is also tight against air and liquids, as can be seen from Figures 8 and 9.
• a metering cap 5 is slidably arranged on the filler neck.
• the dosing cap 5 is displaceable in the axial direction and to a limited extent with respect to the filler neck 4.
• the arrangement can also be designed so that the cap 5 is rotatable in relation to the filler neck in the circumferential direction.
• the other theoretically possible relative movement between the two parts can be blocked by corresponding guide elements.
• a helix can also be implemented in order to achieve the movement of the filler cap with respect to the filler device (with the connecting pieces).
• the dosing cap 5 can only be displaced in the axial direction with respect to the filler neck 4, to be precise to a limited extent, as shown by the double arrow 25 in FIG. 3.
• the filler neck 4 is axially open at both ends, 14, 14a.
• the mounting end 15 is profiled on the outside in such a way that it can be inserted sealingly and firmly into the open end 8 of the housing 1.
• the filler neck has an outer, shoulder-like profile, as shown at 20 in FIG. This in particular circumferential shoulder-like profiling 20 forms a limit stop which determines the closed position of the filling device.
• the filling or dosing cap 5 is closed at one end 9.
• An opposite section is axially displaceable, in particular sliding, on the filler neck 4.
• FIGS. The closed position of the filling device is shown in FIGS. It can be seen from FIG. 6 that the shoulder-like profile section 20 of the filler neck 4 in this position interacts with a corresponding inner shoulder section 21 of the metering cap 5 by these areas sealingly engaging and limiting the axial movement. In this closed position, a front end 10 of the metering cap 5 comes almost in the stop position to the end 8 of the housing 1, into which the filler neck is inserted.
• the metering cap has, over part of its axial length, two opposing, axially extending, but laterally (radially) directed filling opening windows 11a, 11b (short 11). These begin near the end 10 of the cap 5 and end shortly before or at the inner shoulder area 21 according to FIG. 6.
• the area of the cap 5 after the inner shoulder 21 according to FIG. 6 is circumferential and closed to the end, the wall thickness in the axial extension 12 the window 11 is reduced.
• the area between the closed end 9 and the inner shoulder area 21 forms the metering area 12 of the cap 5 as an intermediate store for the absorption and metering of the liquid filling quantity 12 '
• the filler neck has two lateral stop cams 16a, 16b (short 16) in the area of its axial outer fill opening 14, which engage in the windows 11a, 11b and thus limit the open position of the filler device, as shown in FIGS. 1 to 4.
• the outer filling opening 14 of the filler neck is exposed via the radial windows 11a, 11b.
• the metering area 12 'of the cap 5 is through the side Filling openings 11 freely accessible and can therefore be easily filled with the appropriate amount of liquid.
• the writing instrument is held in the position according to FIGS. 1 and 3, that is to say vertically, with the writing tip pointing upwards.
• the cap 5 is moved upward on the filler neck 4 after the dosing volume 12 has been filled, until the sealing regions 20 and 21 interlock and the lateral filler opening windows 11 are closed.
• the metering area of the cap 5 is thus closed, approximated to the main storage 6, and in free connection with the storage volume 6 of the housing 1 via the inner filling opening 14a. If the device is now brought into the inverted, vertical position, the liquid flows from the metering area 12 (intermediate storage) of the cap 5 into the storage area 6 (main storage) of the writing instrument and there into the fiber storage 6a, as illustrated in FIG. 9.
• two limiting cams 16 come to rest against the end 23 of the filling opening window 11, as shown in FIG. 3.
• FIG. 4 enables a free view of the metering volume 12 in the area of the container-shaped wall section of the metering cap 5, while the axial (outer) fill opening 14 of the filler neck 4 can be seen through the lateral fill opening window 11a.
• a part of the opposite side fill opening window 11b can also be seen in FIG.
• the cam-like stops 16 are the locking cams 16a and 16b.
• Each of these cams has two not identical axial end sections. One of them is designed as a ramp slope 16 ', another as a stop point 16 ".
• the former serves to allow the writing cap 5 to snap with its front end 10 over the ramp slopes and the cams after manufacture with a certain elasticity, so that they snap in the window 11a, 11 b come to rest.
• the steeper stop 16 "serves to reach the stop in the extended position (the open position) on the front edge 23 of the windows.
• This front edge 16 ′′ can also be designed in a manner as shown in more detail in FIG can be seen.
• a curvature 16 * can be seen which strikes the edge 23 with its pointed ends when the filling position of the writing cap 5 is reached.
• the filling device as it is shown as such in Figures 5 and 7, can be easily used as a pre-assembled unit sealingly and firmly in the open end 8 of the housing 1 of a device.
• the operation is extremely simple, whereby only the position of the device when filling and until the sealing cap is pushed on must be observed.
• FIG. 8 is an inverted representation of FIG. 6, the intermediate region between the tapered front section 4a and the section 4b of the filler neck 4 located behind it being illustrated.
• a flow opening 14b is provided, which opens an axial flow path, which offers a backflow possibility for stored air from the front storage 6 between the tapered section 4a and the radially larger section 4b.
• FIG. 9 illustrates the assembled state of the writing instrument with a section of the main memory 6 with a fibrous memory body 6a inserted therein, which has a radial dimension that is slightly smaller than the inner dimension of the sleeve-shaped writing instrument body 1.
• This circumferential gap is denoted by S. Air flows axially upward from this gap along the flow paths L (after the writing instrument has been turned from the position in FIG. 3) when the metered liquid flows along the flow path W through the front section 4a of the filler neck 4 into the storage body 6a.
• the pressure equalization takes place via the flow opening 14b, which was explained in FIG. 8.
• FIG. 9 Shown in FIG. 9 is the closed state of the dosing cap 5, in which the shoulder-like sealing sections engage in a sealing manner at the axially outer end 14 and on an inner region of the dosing cap 5.
• the metering volume 12, which was explained in FIG. 4, lies above this sealing section.
• FIG. 9 and FIG. 4 can also be described in such a way that a metering volume or a filling volume on at least two arms 5 ′ and 5 ′′ are kept at a distance from the rear section 8 of the device housing 1.
• the dosing cap 5 If the dosing cap 5 is displaced as a whole or moved circumferentially, as previously described with the aid of a rotary movement or a helical movement, the dosing volume 12 on the arms 5 ′ and 5 ′′ moves away from the main store 6 in order to be filled. After filling and Intermediate storage, it can be approximated again to the device housing via the arms, the windows 11a, 11b remaining between the arms being closed when the sealing regions 20, 21 described above engage (in particular engage or engage).
