Description

  • Die Erfindung betrifft einen Füllfederhalter, insbesondere Patronenfüllfederhalter, mit einem auswechselbaren Löschteil, das sich an dem der Schreibfeder entgegengesetzten Gehäuseende befindet, und aus einer Löschpatrone mit Spitze besteht und mittels einer an die Gehäusehülse angepaßten Endkappe abgedeckt ist, wobei sowohl die Gehäusehülse als auch die Endkappe zur Aufnahme und Abdichtung des Löschteiles ausgebildet ist. The invention relates to a fountain pen, in particular Cartridge, having a replaceable erasing part to which the nib opposite end of the housing is located, and consists of an erasing cartridge with a tip and is covered by a matched to the housing sleeve end cap, wherein both the housing sleeve and the end cap is designed for receiving and sealing the erase part.
  • Ein Füllfederhalter dieser Art ist durch die DE-U 8 317 634 bekannt. A fountain pen of this type is known from DE-U 8,317,634. Dieses Schreibgerät bietet die Möglichkeit, das Löschteil entweder gemeinsam mit dem Halter oder getrennt davon zu benutzen. This writing instrument offers the possibility to use the extinguishing part, either together with the holder or separately.
  • Bei einer in der Praxis durchaus bewährten Ausführungsform des durch das genannte Gebrauchsmuster bekannten Füllfederhalters, wird es als nachteilig angesehen, daß für die Abdichtung der Spitze, die wegen der über einen Docht sich leicht verflüchtigenden Löschflüssigkeit bei Nichtbenutzung des Löschteils unbedingt erforderlich ist, sowohl in der Gehäusehülle als auch in der Endkappe je eine Dichtung vorhanden sein muß. In a thoroughly tried and tested in practice embodiment of the known through said utility model fountain pen, it is considered disadvantageous for the sealing of the tip, which is absolutely necessary because of the readily volatilized via a wick extinguishing liquid when not using the erasing part, both in that pod shell as must also be present in the end cap each have a seal.
  • Da diese Dichtungen, die in Form von je einer Dichtkappe in der Gehäusehülse und in der Endkappe vorgesehen sind, einen relativ großen, durch den Platzbedarf der Löschpatrone bedingten Hohlraum aufweisen, besteht der Nachteil, daß Löschflüssigkeit in diesen Raum hinein verdunsten kann. As these seals are provided in the form of a respective sealing cap in the housing sleeve and the end cap having a relatively large, due to the space requirements of the erasing cartridge cavity, there is the disadvantage that extinguishing liquid can evaporate into this space.
  • Es wird ferner als nachteilig erachtet, daß für den Füllfederhalter vorgesehene Ersatzlöschteile bis zu ihrem Einsatz eine eigene Schutzkappe tragen müssen, die der Verbraucher vor dem Austausch der Löschteile entfernen und wegwerfen muß. It is also considered disadvantageous that have to carry a separate cap for the pen provided for spare parts extinguishing until its use, which must remove consumers from the exchange of the extinguishing parts and discard.
  • Der Erfindung liegt die Aufgabe zugrunde, einen Füllhalter der eingangs genannten Art so auszubilden, daß der Aufwand für die erforderliche Abdichtung der Löschspitze wesentlich vermindert ist. The invention has for its object to design a fountain pen of the type mentioned such that the effort required for the necessary sealing of the erasing tip is substantially reduced.
  • Diese Aufgabe wird erfindungsgemäß mit den im Kennzeichen des Patentanspruchs 1 angegebenen Merkmalen gelöst. This object is achieved with the features specified in characterizing part of patent claim 1.
  • Die weitere Ausbildung des Erfindungsgegenstandes geht aus dem Unteranspruch hervor. The further development of the subject matter is evident from the dependent claim.
  • Die mit der Erfindung erzielten Vorteile bestehen darin, daß der Füllfederhalter keine eingebauten Dichtungen aufweisen muß, weil der Löschteil selbst eine Dichtkappe hat, die die Funktion der bisher in der Gehäusehülle und der Endkappe vorgesehenen Dichtkappen allein übernimmt. The advantages achieved with the invention consist in the fact that the pen need not have a built-in seals, because the erasing member itself has a sealing cap, which takes over the function of the previously in the pod shell and the end cap provided sealing caps alone. Ersatzlöschteile sind somit genauso gestaltet wie das für die ursprüngliche Ausrüstung des Füllfederhalters vorgesehene Löschteil, und die nun ständig der Spitze angeordnete Dichtkappe umgibt den Docht mit geringem Zwischenraum, in den hinein Löschflüssigkeit nur in unwesentlicher, praktisch vernachlässigbarer Menge verdunsten kann. Replacement extinguishing parts are thus designed as well as the for the original equipment of the pen erase part, and the now constantly arranged the tip sealing cap surrounding the wick with a small gap can evaporate only in insignificant, practically negligible quantity into which extinguishing liquid.
  • Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und werden nachstehend erläutert. Embodiments of the invention are illustrated in the drawings and are explained below. Es zeigen Show it
  • Fig. 1 einen Längsschnitt des hinteren Teils einer Patronenfüllfederhaltergehäusehülse mit Löschteil und Endkappe, wobei sich die Löschpatrone in der Gehäusehülse befindet und Fig. 1 is a longitudinal section of the rear portion of a Patronenfüllfederhaltergehäusehülse with erasing member and end cap, with the extinguishing cartridge is in the housing sleeve and
  • Fig. 2 eine der Fig. 1 entsprechende Darstellung, bei der sich jedoch die Löschpatrone in der Endkappe befindet und das Löschteil eine sogenannte Tamponausführung mit langem Docht ist. Fig. 2 is a like FIG. 1 illustration, but the erasing cartridge is in the in the end cap and the erase part is a so-called tampon version with long wick.
  • In den Darstellungen sind einander entsprechende Teile mit denselben Bezugszeichen versehen. In the illustrations, like parts are each provided with the same reference numerals. Die in den beiden Figuren abgebildeten unterschiedlichen Löschteile haben jeweils in der oberen und unteren Hälfte voneinander abweichende Konstruktionsformen, womit lediglich Gestaltungsmöglichkeiten der Löschpatrone und der Löschspitze gezeigt sind. The shown in the two figures differing erase parts each in the upper and lower halves of differing forms of construction, which merely design possibilities of the erase cartridge and the extinguishing tip are shown.
  • Der in den Figuren 1 und 2 dargestellte Patronenfüllfederhalter, dessen Tintenpatrone 1 nur angedeutet ist, hat ein auswechselbares Löschteil 2, 3, das sich im Gehäuseende befindet und aus einer Löschpatrone 2 mit Spitze 3 besteht und mittels einer an eine Gehäusehülse 4 angepaßten Endkappe 5 abgedeckt ist. The Cartridge shown in Figures 1 and 2, the ink cartridge 1 is only indicated, having a replaceable erasing part 2, 3, located in the housing end and consists of an erasing cartridge 2 with tip 3 and covered by a fitted to a housing sleeve 4 end cap 5 is. Das Löschteil 2, 3 weist eine einen Docht 6 in der Spitze 3 mit geringem Abstand überdeckende Dichtkappe 7 auf, die auf die Spitze 3 form- und reibschlüssig aufgesetzt ist. The erasing part 2, 3 comprises a wick 6 in the tip 3 covering a small distance the sealing cap 7, which is fitted positively and frictionally engaged to the tip. 3 Die formschlüssige Verbindung wird mittels einer Kerbzahnprofil-Verbindung 8 bewirkt. The positive connection is effected by means of a serrated profile connection. 8
  • An ihrem offenen Ende ist die Dichtkappe 7 mit einem Außengewinde 9 versehen, das identisch mit einem am löschpatronenseitigen Ende der Spitze 3 ausgebildeten Außengewinde 10 ist. At its open end the sealing cap 7 is provided with an external thread 9, which is identical to a formed on the deleted cartridge-side end of the tip 3 external thread 10th Die Gehäusehülse 4 sowie die Endkappe 5 weisen mit den Außengewinden 9 und 10 der Dichtkappe 7 und der Spitze 3 korrespondierende Innengewinde 11 bzw. 12 auf, so daß das mit der Dichtkappe 7 versehene Löschteil 2, 3 entweder mit der Löschpatrone 2 voran in die Gehäusehülse 4 (s. Fig. 1) oder in die Endkappe 5 (s. Fig. 2) eingeschraubt werden kann. The housing sleeve 4 and the end cap 5 have the external threads 9 and 10 of the sealing cap 7 and the point 3 corresponding internal thread 11 and 12, respectively, so that the provided with the sealing cap 7 erasing section 2, 3 with either the erase cartridge 2 forward in the housing sleeve or may be screwed 4 (s. Fig. 1) into the end cap 5 (see. Fig. 2). In beiden Fällen sorgt dabei die Kerbzahnprofil-Verbindung 8 zwischen Dichtkappe 7 und Spitze 3 für den erforderlichen Formschluß. In both cases, the serrated profile connection 8 between the sealing cap 7 and the tip 3 of the necessary positive engagement ensures. Die gleichzeitige Ausbildung dieser Verbindung als reibschlüssige Verbindung gewährleistet einen sicheren Sitz der entweder mit der Dichtkappe 7 oder mit der Spitze 3 verbundenen Endkappe 5 am Ende der Halterhülse 4. The simultaneous formation of this compound as a frictional connection ensures a secure seat of the associated either with the sealing cap 7, or with the tip 3 of the end cap 5 at the end of the holder sleeve. 4
  • Der Löschpatrone 2 in Fig. 1 ist mit Löschflüssigkeit 13 gefüllt und am Patronenende mit einer Silikonscheibe 14 verschlossen, wobei auf deren der Flüssigkeit abgewandten Seite ein Luftraum 15 verbleibt. The erase cartridge 2 in Fig. 1 is filled with extinguishing fluid 13 and sealed on the cartridge end with a silicon wafer 14, wherein the side facing away from the liquid remains an air space is 15 °.
  • Die Löschpatrone 2 in Fig. 1 enthält einen mit Löschflüssigkeit getränkten Tampon 16 und ist am Ende geschlossen. The erase cartridge 2 in Fig. 1 includes an extinguishing liquid impregnated pad 16, and is closed at the end.
  • Die Verwendungsweise des Löschteils 2, 3 ist variabel. The use of the erasing part 2, 3 is variable. Bei einer Anordnung, wie sie Fig. 1 zeigt, verbleibt das Löschteil 2, 3 nach Abziehen der Endkappe 5, mit der auch die Dichtkappe 7 abgezogen wird, in der Gehäusehülse 4, dh der Benutzer des Füllfederhalters dreht diesen dann lediglich um, wenn er Geschriebenes löschen will. In one arrangement, as shown in Fig. 1, remains the deletion part 2, 3 after removal of the end cap 5 is drawn with the sealing cap 7, in the housing sleeve 4, the user of the pen then that rotates it by only if he wants to erase written.
  • Bei einer Anordnung gemäß Fig. 2 wird das Löschteil 2, 3 mittels der Endkappe 5 aus der Gehäusehülse 4 gezogen, wobei die Dichtkappe 7 in der Gehäusehülse 4 verbleibt. In an arrangement according to FIG. 2, the erasing section 2, 3 is drawn out of the housing sleeve 4 by means of the end cap 5, wherein the sealing cap 7 remains in the housing sleeve 4.
