Description

Die Erfindung betrifft einen Füllfederhalter; sie bezweckt, bei Füllfederhaltern mit auswechselbarer Tintenpatrone den gleichmäßigen Zustrom der Tinte von der Patrone zur Feder zu bewirken.The invention relates to a fountain pen; it aims at fountain pens with replaceable ink cartridges ensure an even flow of ink from the cartridge to cause spring.

Bekannt ist bei Füllfederhaltern die Verwendung von Tintenpatronen, deren Verschluß mittels einer Röhre durchstochen wird, welche die Tinte zur Feder leiten soll. Die bisher verwendeten Röhren können jedoch diese Aufgabe nicht erfüllen, weil sie die physikalischen Gesetze der Kapillarwirkung und Oberflächenspannung nicht berücksichtigen. Wegen dieses Fehlens eines wirksamen Tintenleiters hat sich bisher die Verwendung einer austauschbaren Tintenpatrone nicht verwirklichen lassen.The use of ink cartridges is known in fountain pens, the closure of which is pierced by a tube which carries the ink to the pen should lead. However, the tubes used so far cannot fulfill this task, because they adhere to the physical laws of capillary action and surface tension do not take into account. Because of this lack of an effective ink guide so far the use of a replaceable ink cartridge can not be realized.

Die Aufgabe der Erfindung ist, die Möglichkeit eines zweckentsprechenden Tintenstroms von der Tintenpatrone zur Feder zu schaffen. Dies geschieht durch Verwendung eines Tintenleiters aus eng ineinandergepaßten Röhren aus korrosionssicherem Material.The object of the invention is the possibility of an appropriate To create a flow of ink from the ink cartridge to the nib. It does this by using an ink feed of closely fitted tubes made of corrosion-resistant material.

In der Zeichnung stellen a und b diese beiden Röhren dar. Sie sind durch den Gummiverschluß c in die Tintenpatrone d eingeführt und an diesem Ende schrägspitz geformt, um das Durchstechen des Gummiverschlusses zu ermöglichen. Die beiden Röhren sind so ineinandergesteckt, daß zwischen ihnen ein kapillarer Raum entsteht. Das federseitige Ende der Röhren ist gebogen und schräg abgeschliffen, so daß es an den Federspalt anliegt.In the drawing, a and b represent these two tubes. They are inserted through the rubber cap c into the ink cartridge d and at this end Shaped at an angle to enable the rubber seal to be pierced. the the two tubes are inserted into one another in such a way that a capillary space is created between them arises. The spring-side end of the tubes is bent and ground off at an angle, so that it rests against the spring gap.

Der Vorgang ist folgender: In den Raum zwischen Röhre a und b wird vermöge der Kapillarkraft Tinte angesaugt und bis an die Feder geführt. Dieser Vorgang erzeugt einen geringen Unterdruck in der Tintenpatrone, durch den Luft durch die Innenröhre a angesaugt.wird. Hierdurch wird die Oberflächenspannung am tintenpatronenseitigen Ende der Innenröhre a gestört. Dadurch und vermöge des Kommunikationsprinzips kann nun auch Tinte in die Innenröhre einfließen. Dieser Vorgang wiederholt sich nach Maßgabe des Tintenverbrauchs beim Schreiben, wobei jeweils Luft durch die Innenröhre in die Tintenpatrone nachgesaugt wird.The process is as follows: Ink is sucked into the space between tubes a and b by means of the capillary force and guided up to the spring. This process creates a slight negative pressure in the ink cartridge, by means of which air is drawn in through the inner tube a. As a result, the surface tension at the end of the inner tube a on the ink cartridge side is disturbed. Because of this and because of the communication principle, ink can now also flow into the inner tube. This process is repeated according to the amount of ink used when writing, with air being sucked through the inner tube into the ink cartridge.
