Abstract

1. Ink cartridge fountain pen with compensating device and separate channels for ink and air, whereby a part of the air channel is formed to act as control path for uniform ink supply, and with a receiving stud for the replaceable ink cartridge at the rear end of the compensating device, characteirzed in that the control path (16, 40) contained in the air channel (14, 39) for controlling the ink supply is formed of boundary surfaces (17, 42) at the compensating device (13, 38) and of boundary surfaces (5a, 43) at the cartridge front part (5) after inserting eh cartridge into the fountain pen.

Description

Die Erfindung betrifft einen Tintenpatronen-Füllfederhalter mit Ausgleichsvorrichtung und getrenntem Tintenund Luftkanal, wobei ein Teil des Luftkanals als Regelstrecke für gleichmäßigen Tintenzufluß ausgebildet ist, sowie mit einem Aufnahmestutzen für die auswechselbare Tintenpatrone am rückwärtigen Ende der Ansgleichsvorrichtung.The invention relates to an ink cartridge fountain pen with a compensation device and a separate ink and air channel, part of the air channel being designed as a control path for uniform ink flow, and with a receiving nozzle for the exchangeable ink cartridge at the rear end of the matching device.

Füllfederhalter werden entweder aus einem Tintenvorrat gespeist, der im hohlen Halterschaft untergebracht ist und mittels eines Pump- oder Saugmechanismus dort hineingelangt, oder aus einer auswechselbaren Tintenpartrone, die in den ebenfalls hohlen Halterschaft eingesetzt werden kann.Fountain pens are either fed from an ink supply, which is accommodated in the hollow holder shaft and gets there by means of a pump or suction mechanism, or from an exchangeable ink cartridge that can be inserted into the likewise hollow holder shaft.

In allen Fällen befindet sich zwischen dem Tintenvorrat und der Schreibspitze ein System von Kapillarkanälen und -kammern, das für einen Nachfluß der Tinte bei gleichzeitigem angemessenem Nachschub an Ersatzluft in den Tintenvorratsraum sorgt.In all cases there is a system of capillary channels and chambers between the ink supply and the writing tip, which ensures that the ink continues to flow while at the same time supplying adequate replacement air to the ink supply space.

Tintenleitsysteme dieser Art gibt es seit langem in großer Zahl und Vielfalt. Die Systeme der sogenannten "Kolbenfüllfederhalter" oder auch "mechanisch nachfüllbaren Füllfederhalter" können hier außer Betracht bleiben, denn die vorliegende Erfindung bezieht sich ausschließlich auf den Typ der Tintenpatronen-Füllfederhalter.Ink guidance systems of this type have long been available in large numbers and diversity. The systems of the so-called "piston fountain pens" or "mechanically refillable fountain pens" can be disregarded here, because the present invention relates exclusively to the type of ink cartridge fountain pens.

Die Tintenpatronen sind zunächet allseitig verschlossen, und zwar an der Stirnseite entweder durch eine Membran oder durch einen in einer ringförmigen Öffnung im Preßsitz eingesetzten Verschlußkörper, sei es in Gestalt einer Kugel oder eines anderen rotationssymmetrischen Körpers.The ink cartridges are initially sealed on all sides, namely on the front side either by a membrane or by a closure body inserted into an annular opening in the press fit, be it in the form of a ball or another rotationally symmetrical body.

Erst beim Aufsetzen der Patrone auf die im Vorderteil des Füllfederhalters befindliche Patronenaufnahme wird die Patrone geöffnet, nämlich entweder der Verschlußkörper in den Innenraum der Patrone gestoßen oder die Membran aufgeschnitten.The cartridge is only opened when the cartridge is placed on the cartridge receptacle located in the front part of the fountain pen, namely either the closure body is pushed into the interior of the cartridge or the membrane is cut open.

Nach dem Einsetzen der Patrone verläuft dann ein Kanal vom Tintenvorratsraum bis zur Spitze der Feder, wobei in dem Tintenzuführkanal eine Ausgleichsvorrichtung mit Kanälen vorgesehen ist, die bei einer Erwärmung aus der Patrone austretende Tinte in ausreichendem Maße aufnehmen können, um ein Klecksen zu verhindern.After the cartridge has been inserted, a channel then runs from the ink supply space to the tip of the spring, a compensation device having channels being provided in the ink supply channel, which channels can absorb ink which exits the cartridge when heated to a sufficient extent in order to prevent blobbing.

Bei Konstruktionen dieser Art muß die den Druckausgleich herbeiführende Luft sich gegen den Tintenstrom bewegen, wobei sich verhältnismäßig große Luftblasen bilden können, die keinen gleichmäßigen Tintenzufluß gewährleisten können.In constructions of this type, the air which brings about the pressure equalization has to move against the ink flow, and relatively large air bubbles can form which cannot ensure a uniform flow of ink.

Aus DE-A-22 16 706 ist es bekannt, eine solche Ausgleichskammer in die Patrone selbst zu verlegen, so daß Reinigungsprobleme für die Ausgleichskammer entfallen, weil diese nach verbrauchter Patrone mit dieser entfernt wird, und durch eine saubere Ausgleichskammer in der neuen Patrone ersetzt wird.From DE-A-22 16 706 it is known to move such a compensation chamber into the cartridge itself, so that cleaning problems for the compensation chamber are eliminated because the cartridge is removed after the cartridge has been used up and replaced by a clean compensation chamber in the new cartridge becomes.

Es ist auch bekannt, im Tintenzuführungskanal eine Regelstrecke oder einen Regeldurchlaß vorzusehen, der so bemessen ist, daß die den Druckausgleich besorgende Luft in Form einer gleichförmigen Schnur kleiner Luftbläschen die Tintensäule im Gegenstrom durchwandert, so daß ein geregelter Strom von Luftbläschen gebildet wird, der unter allen atmosphärischen Bedingungen einen stets gleichmäßigen und störungsfreien Tintenfluß gewährleistet.It is also known to provide a control path or a control passage in the ink supply channel which is dimensioned such that the air which provides the pressure compensation in the form of a uniform string of small air bubbles travels through the ink column in countercurrent, so that a regulated flow of air bubbles is formed which is formed under guarantees an even and trouble-free ink flow in all atmospheric conditions.

Die Verwendung eines gemeinsamen Kanals für die Tintenzuführung zur Schreibspitze und für die Ausgleichsluft kann jedoch zu Begrenzungen führen, wenn breite Federn verwendet werden, die einen verhältnismäßig hohen Tintenzufluß erfordern.However, the use of a common channel for the ink supply to the writing tip and for the compensation air can lead to limitations if wide nibs are used, which require a relatively high ink flow.

Es ist daher auch bekannt, für den Tintenzufluß und die Ausgleichsluft getrennte Kanäle vorzusehen, wobei dann die Ausgleichsstrecke in dem Luftkanal angeordnet wird. In jedem Falle befindet sich dabei die Regelstrecke im Haltervorderteil, wodurch sich im Hinblick auf die geringen Abmessungen der Regelstrecke das Problem ergibt, daß sich die Regelstrecke durch austrocknende Tinte zusetzen kann und sich dann schwer reinigen läßt, weil zu ihr kein unmittelbarer Zugang besteht.It is therefore also known to provide separate channels for the ink flow and the compensation air, in which case the compensation section is then arranged in the air channel. In any case, the controlled system is located in the front part of the holder, which gives rise to the problem in view of the small dimensions of the controlled system that the controlled system can become clogged by drying ink and is then difficult to clean because there is no direct access to it.

Der Erfindung liegt die Aufgabe zugrunde, bei einem Patronen-Füllfederhalter der eingangs genannten Art eine Regelstrecke für die Ersatzluft zu schaffen, die während des gesamten Gebrauchs der betreffenden Tintenpatrone voll wirksam bleibt und bis zum letzten Tintentropfen einen gleichmäßigen Tintenfluß veranlaßt sowie leicht zu reinigen ist.The invention has for its object to provide a control system for the replacement air in a cartridge fountain pen of the type mentioned, which remains fully effective throughout the use of the ink cartridge in question and causes an even flow of ink until the last drop of ink and is easy to clean.

Die gestellte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die im Luftkanal enthaltene Regelstrecke für die Regelung der Tintenabgabe aus Grenzflächen an der Ausgleichsvorrichtung und aus Grenzflächen an dem Patronenvorderteil nach dem Einsetzen der Patrone in den Füllfederhalter gebildet wird.The object is achieved according to the invention in that the control path contained in the air duct for regulating the ink delivery is formed from interfaces on the compensating device and from interfaces on the front part of the cartridge after inserting the cartridge into the fountain pen.

Diese Regelstrecke, durch die sich die Ersatzluft in Gestalt von Luftblasen geradezu zwängen muß, kann parallelwandig oder auch konisch ausgebildet sein.This controlled system, through which the replacement air in the form of air bubbles has to squeeze, can be parallel-walled or conical.

An der Tintenpatrone, am Haltervorderteil oder am Tintenleitsystem können Ringstege für korrekten Sitz der Tintenpatrone und damit für stets gleichen Querschnitt sorgen. An der Tintenpatrone kann die Öffnungsmembran versetzt angeordnet sein, so daß der eine Teil dieser Membran durchstoßen wird, während der andere Teil unverletzt bleibt und eine Wand der Regelstrecke bildet. Schließlich kann mit Hilfe von Zentriernocken an der Außenwand der Tintenpatrone in Verbindung mit Leitnuten im Haltervorderteil, oder umgekehrt stets korrektes, seitengerechtes Einsetzen der Tintenpatrone in den Füllfederhalter gesichert werden.Ring bars on the ink cartridge, on the front part of the holder or on the ink guide system can ensure that the ink cartridge is correctly seated and thus always have the same cross-section. The opening membrane can be staggered on the ink cartridge, so that one part of this membrane is pierced, while the other part remains uninjured and forms a wall of the controlled system. Finally, with the help of centering cams on the outer wall of the ink cartridge in connection with guide grooves in the front part of the holder, or vice versa, it is always correct secure, right-sided insertion of the ink cartridge into the fountain pen.
