Definitions
- the invention relates to a felt-tip pen with a housing in which a tampon made of absorbent material for storing its ink is arranged and to which a separate refill device is assigned, which has a chamber filled with ink.
- Felt-tip pens of the above type are built in very different embodiments and are used, for example, for writing and drawing on pin boards in huge quantities. For ecological reasons, it is unsatisfactory for felt pens to go to waste as soon as their ink has been used up.
- Refill devices have therefore been developed with which ink can be dripped from a relatively large-volume chamber into the housing of the felt-tip pen after a cover on the side of the felt-tip pen housing facing away from the writing tip has been removed.
- a refill device designed as a pipette reference is made to DE-C-911 185.
- An elastic ball is attached to the outside of the lid of a refill bottle and a tube is attached to the inside of the lid, which is immersed in the liquid of the refill bottle.
- the invention is based on the problem of designing a felt-tip pen with a separate refill device in such a way that the refill can be carried out as simply as possible and without risk of contamination of the surroundings.
- refilling without unscrewing or removing a cover of the felt-tip pen housing can be done in a very simple manner by piercing the area of the felt-tip pen housing intended for this purpose with the injection needle of the refill device, then the ink from the Refill device transferred to the felt tip pen and then simply pulls the injection needle out of the felt tip pen again.
- the volume of the chamber corresponds to the maximum amount of ink to be held by the tampon due to its absorbency. This ensures that no larger amount of ink can be entered in the felt pen than is able to hold due to the size and absorbency of its tampon.
- too much ink was very often filled into the felt-tip pen. When As a result of such overfilling, too much ink gets to the felt and drips out of the felt-tip pen, which generally means that the user never refills a felt-tip pen again.
- the felt pen can be made of an inexpensive and solid material if the area to be pierced by the injection needle is formed by an elastic insert in the housing of the felt pen.
- the felt-tip pen is particularly simple to construct and refill if, according to another embodiment of the invention, the insert is provided in the upper end face of the housing.
- Penetration of the insert by means of the injection needle can be facilitated if the insert has a prefabricated passage which is closed by the elasticity of its material.
- the refill device is particularly simple and at the same time storage container for the liquid to be refilled in the felt-tip pen, if, according to another development of the invention, the chamber is provided on the outside and the injection needle on the inside on a lid of a refill bottle and the injection needle projects into the refill bottle when the lid is attached.
- Such a refill device can be refilled in a simple manner, similar to a pipette of a dropper bottle, by squeezing its chamber and then sucking in liquid from the closed bottle, without there being any risk of contamination of the environment. Therefore, the refill device can be used at least as often until the refill bottle is empty. Furthermore, there is no risk of injury from the injection needle when storing the refill device.
- the injection needle only just protrudes into the bottle neck of the refill bottle when the lid is in place.
- a refill has several advantages. Since the injection needle is very short and does not protrude or hardly protrudes beyond the height of the edge of the lid, the risk of injury to the injection needle is very low even when handling the lid with the injection needle.
- the refill bottle must be held overhead so that the end of the injection needle is immersed in the liquid. The result of this is that foam in the liquid floats far away from the needle on the liquid level then pointing to the bottom, so that no foam is sucked in with the needle.
- the cover facilitates the centering of the injection needle on the housing of the felt-tip pen and fixes the chamber on the housing when refilling, if, according to another development of the innovation, the cross-section of the cover is designed to be placed on the housing of a felt-tip pen during the refilling process.
- FIG. 1 shows a felt pen 1 in perspective, which has a cylindrical housing 2 with a cover 3.
- a fiber tip 4 protrudes downward from the housing 2, which receives ink for writing from a tampon 5 soaked with ink and arranged within the housing 2.
- An insert 6 made of an elastic material, preferably rubber, is arranged in the cover 3 of the housing 1.
- a refill device 7, which essentially consists of a ball-like, elastic hollow body 8 with a chamber 9 and an injection needle 10, serves to refill the felt-tip pen 1.
- the volume of this chamber 9 is dimensioned so that just the amount of ink that is needed to soak the tampon 5 can be present in it.
- the insert 15 is pierced with the injection needle 10 and then the ball-like body is pressed together, so that the ink comes from the chamber 9 into the felt-tip pen 1. Then you pull the refill 7 back again. Due to the elasticity of the insert 6, the hole in the insert 6 closes by itself as soon as the injection needle 10 comes out of it.
- FIG. 2 shows a refill bottle 12 which tapers uniformly in cross-section from a base 16 to its bottle neck 13.
- a lid 11 can be screwed onto the bottle neck 13 from above, for which purpose the lid 11 has an internal thread 17 and the bottle neck 13 has an external thread 18.
- the refill bottle 12 shown is initially held upside down when the lid 11 is screwed on. Then, with two fingers, the chamber 9, which is designed as an elastic ball, is pressed together, as a result of which the air in it reaches the refill bottle 12. When the chamber 9 is released, it returns to its original shape and soaks up liquid.
- the cap 11 is unscrewed from the refill bottle 12 and its injection needle 10 is pierced through the area provided in the upper end face of the felt pen 1 until the cap 11 is placed on the housing 2 of the felt pen 1.
- the injection needle 10 is dimensioned in terms of its length such that it then only reaches a space above the tampon 5 of the felt-tip pen 1. This makes it possible to quickly transfer the liquid present in it into the felt-tip pen 1 by pressing on the chamber 9 designed as an elastic ball, since no high flow resistance can be overcome.
- the volume of the chamber 9 can be dimensioned so that it corresponds exactly to the amount of liquid required for a conventional felt-tip pen. For thicker felt pens, the refill process must be carried out twice. Regardless of the size of the chamber 9, however, the refill bottle 12 according to the invention enables precise dosing of the required refill volume, which is particularly important if a felt-tip pen is used for refilling is not completely empty, so that an amount of liquid that cannot be determined exactly must be refilled.

Abstract
Description
Die Erfindung betrifft einen Filzschreiber mit einem Gehäuse, in dem ein Tampon aus saugfähigem Material zum Speichern seiner Tusche angeordnet und dem eine separate Nachfüllvorrichtung zugeordnet ist, welche eine mit Tusche gefüllte Kammer aufweist.The invention relates to a felt-tip pen with a housing in which a tampon made of absorbent material for storing its ink is arranged and to which a separate refill device is assigned, which has a chamber filled with ink.
Filzschreiber der vorstehenden Art werden in sehr unterschiedlichen Ausführungsformen gebaut und beispielsweise zum Schreiben und Zeichnen auf Pinnwänden in riesigen Mengen verwendet. Aus ökologischen Gründen ist es unbefriedigend, wenn Filzschreiber zum Abfall gelangen, sobald ihre Tusche aufgebraucht ist. Deshalb sind Nachfüllvorrichtungen entwickelt worden, mit denen man aus einer relativ großvolumigen Kammer Tusche in das Gehäuse des Filzschreibers tropfen lassen kann, nachdem man einen Deckel an der der Schreibspitze abgewandten Seite des Gehäuses des Filzschreibers entfernt hat. Als Beispiel für eine solche als Pipette ausgebildete Nachfüllvorrichtung sei auf die DE-C-911 185 verwiesen. Bei ihr ist außenseitig am Deckel einer Nachfüllflasche ein elastischer Ball und innenseitig am Deckel eine Röhre befestigt, die in die Flüssigkeit der Nachfüllflasche eintaucht.Felt-tip pens of the above type are built in very different embodiments and are used, for example, for writing and drawing on pin boards in huge quantities. For ecological reasons, it is unsatisfactory for felt pens to go to waste as soon as their ink has been used up. Refill devices have therefore been developed with which ink can be dripped from a relatively large-volume chamber into the housing of the felt-tip pen after a cover on the side of the felt-tip pen housing facing away from the writing tip has been removed. As an example of such a refill device designed as a pipette, reference is made to DE-C-911 185. An elastic ball is attached to the outside of the lid of a refill bottle and a tube is attached to the inside of the lid, which is immersed in the liquid of the refill bottle.
In der Praxis ist das Nachfüllen von Filzschreibern mittels solcher Nachfüllvorrichtungen eine unangenehme Arbeit, da dabei leicht Tusche außerhalb des Filzschreibers gelangen und dann die Umgebung verschmutzen kann. Hiervon abgesehen macht das Nachfüllen beträchtliche Arbeit, weil das Gehäuse des Filzschreibers und die Nachfüllvorrichtung geöffnet und nach dem Füllen wieder verschlossen werden müssen, wobei in beiden Fällen die Gefahr eines Verschüttens von Tusche besteht. In der Praxis wird deshalb meist auf das umständliche Nachfüllen verzichtet, und es werden leer gewordene Filzschreiber immer wieder durch neue ersetzt, was natürlich umweltfeindlich ist.In practice, refilling felt pens using such refill devices is unpleasant work, since ink can easily get outside of the felt pen and then contaminate the surroundings. Apart from this, the refilling does a considerable amount of work, because the housing of the felt-tip pen and the refilling device have to be opened and then closed again after the filling, in both cases the risk of a Spilling ink. In practice, therefore, the cumbersome refilling is usually dispensed with, and felt-tip pens that have become empty are replaced with new ones over and over again, which is of course environmentally unfriendly.
Der Erfindung liegt das Problem zugrunde, einen Filzschreiber mit separater Nachfüllvorrichtung so auszubilden, daß das Nachfüllen möglichst einfach und ohne Gefahr einer Verschmutzung der Umgebung erfolgen kann.The invention is based on the problem of designing a felt-tip pen with a separate refill device in such a way that the refill can be carried out as simply as possible and without risk of contamination of the surroundings.
Dieses Problem wird erfindungsgemäß dadurch gelöst, daß die Kammer der Nachfüllvorrichtung mit einer Injektionsnadel verbunden ist und das Gehäuse des Filzschreibers einen mittels der Injektionsnadel zu durchstechenden Bereich aufweist.This problem is solved according to the invention in that the chamber of the refill device is connected to an injection needle and the housing of the felt-tip pen has an area to be pierced by means of the injection needle.
Bei einem solchen Filzschreiber mit der vorgenannten Nachfüllvorrichtung kann das Nachfüllen ohne Abschrauben oder Abnehmen eines Deckels des Gehäuses des Filzschreibers auf sehr einfache Weise dadurch erfolgen, daß man mit der Injektionsnadel der Nachfüllvorrichtung den hierfür vorgesehenen Bereich des Gehäuses des Filzschreibers durchsticht, dann die Tusche aus der Nachfüllvorrichtung in den Filzschreiber überführt und anschließend einfach die Injektionsnadel wieder aus dem Filzschreiber herauszieht.In such a felt-tip pen with the aforementioned refill device, refilling without unscrewing or removing a cover of the felt-tip pen housing can be done in a very simple manner by piercing the area of the felt-tip pen housing intended for this purpose with the injection needle of the refill device, then the ink from the Refill device transferred to the felt tip pen and then simply pulls the injection needle out of the felt tip pen again.
Eine ganz besonders vorteilhafte Weiterbildung der Erfindung besteht darin, daß das Volumen der Kammer der von dem Tampon maximal aufgrund seiner Saugfähigkeit zu haltenden Tuschemenge entspricht. Hierdurch wird erreicht, daß in den Filzschreiber keine größere Menge Tusche eingegeben werden kann, als dieser aufgrund der Größe und Saugfähigkeit seines Tampons zu halten in der Lage ist. Mit den bisher bekannten Nachfüllvorrichtungen wurde sehr häufig zuviel Tusche in den Filzschreiber gefüllt. Als Folge einer solchen Überfüllung gelangt zu viel Tusche zum Schreibfilz und tropft dort aus dem Filzschreiber heraus, was in aller Regel dazu führt, daß der Benutzer nie wieder einen Filzschreiber nachfüllt.A very particularly advantageous development of the invention is that the volume of the chamber corresponds to the maximum amount of ink to be held by the tampon due to its absorbency. This ensures that no larger amount of ink can be entered in the felt pen than is able to hold due to the size and absorbency of its tampon. With the previously known refill devices, too much ink was very often filled into the felt-tip pen. When As a result of such overfilling, too much ink gets to the felt and drips out of the felt-tip pen, which generally means that the user never refills a felt-tip pen again.
Der Filzschreiber kann insgesamt aus einem kostengünstigen und festen Material ausgebildet sein, wenn der mittels der Injektionsnadel zu durchstechende Bereich durch einen elastischen Einsatz im Gehäuse des Filzschreibers gebildet ist.The felt pen can be made of an inexpensive and solid material if the area to be pierced by the injection needle is formed by an elastic insert in the housing of the felt pen.
Besonders einfach ist der Filzschreiber aufgebaut und nachzufüllen, wenn gemäß einer anderen Ausgestaltung der Erfindung der Einsatz in der oberen Stirnfläche des Gehäuses vorgesehen ist.The felt-tip pen is particularly simple to construct and refill if, according to another embodiment of the invention, the insert is provided in the upper end face of the housing.
Das Durchdringen des Einsatzes mittels der Injektionsnadel kann erleichtert werden, wenn der Einsatz einen vorgefertigten, durch die Elastizität seines Materials geschlossenen Durchlaß aufweist.Penetration of the insert by means of the injection needle can be facilitated if the insert has a prefabricated passage which is closed by the elasticity of its material.
Die Tusche kann auf sehr einfache Weise aus der Kammer über die Injektionsnadel durch Zusammendrücken der Wand der Kammer gepreßt werden, wenn gemäß einer anderen Weiterbildung der Erfindung die Kammer durch den Innenraum eines elastischen, ballartigen Hohlkörpers gebildet ist.The ink can be pressed in a very simple manner out of the chamber via the injection needle by compressing the wall of the chamber if, according to another development of the invention, the chamber is formed by the interior of an elastic, ball-like hollow body.
Die Nachfüllvorrichtung ist besonders einfach ausgebildet und zugleich Vorratsbehälter für die nachzufüllende Flüssigkeit des Filzschreibers, wenn gemäß einer anderen Weiterbildung der Erfindung die Kammer außenseitig und die Injektionsnadel innenseitig an einem Deckel einer Nachfüllflasche vorgesehen sind und die Injektionsnadel bei aufgesetztem Deckel in die Nachfüllflasche ragt.The refill device is particularly simple and at the same time storage container for the liquid to be refilled in the felt-tip pen, if, according to another development of the invention, the chamber is provided on the outside and the injection needle on the inside on a lid of a refill bottle and the injection needle projects into the refill bottle when the lid is attached.
Eine solche Nachfüllvorrichtung kann auf einfache Weise ähnlich wie eine Pipette einer Tropfflasche durch Zusammendrücken ihrer Kammer und anschließendem Ansaugen von Flüssigkeit aus der verschlossenen Flasche wiederholt aufgefüllt werden, ohne daß dabei eine Gefahr der Verschmutzung der Umgebung besteht. Deshalb kann die Nachfüllvorrichtung zumindest so oft benutzt werden, bis die Nachfüllflasche leer ist. Weiterhin besteht beim Aufbewahren der Nachfüllvorrichtung keine Verletzungsgefahr durch die Injektionsnadel.Such a refill device can be refilled in a simple manner, similar to a pipette of a dropper bottle, by squeezing its chamber and then sucking in liquid from the closed bottle, without there being any risk of contamination of the environment. Therefore, the refill device can be used at least as often until the refill bottle is empty. Furthermore, there is no risk of injury from the injection needle when storing the refill device.
Ganz besonders vorteilhaft ist es, wenn gemäß einer Weiterbildung der Erfindung die Injektionsnadel bei aufgesetztem Deckel nur soeben bis in den Flaschenhals der Nachfüllflasche ragt. Eine solche Nachfüllvorrichtung hat verschiedene Vorteile. Da die Injektionsnadel sehr kurz ist und nicht oder kaum über die Höhe des Deckelrandes hinausragt, ist die Gefahr einer Verletzung an der Injektionsnadel auch beim Hantieren mit dem die Injektionsnadel aufweisenden Deckel sehr gering. Weiterhin muß man zum Ansaugen von Flüssigkeit aus der Nachfüllflasche in die Kammer die Nachfüllflasche überkopf halten, damit das Ende der Injektionsnadel in die Flüssigkeit eingetaucht ist. Dadurch ergibt es sich, daß Schaum in der Flüssigkeit weit von der Nadel entfernt auf dem dann zum Boden weisenden Flüssigkeitsspiegels schwimmt, so daß mit der Nadel kein Schaum angesaugt wird. Hinzu kommt, daß es mit einer solchen Ausführungsform möglich ist, die Flüssigkeit in der Nachfüllflasche nahezu bis auf den letzten Rest durch Ansaugen zu verbrauchen.It is very particularly advantageous if, according to a development of the invention, the injection needle only just protrudes into the bottle neck of the refill bottle when the lid is in place. Such a refill has several advantages. Since the injection needle is very short and does not protrude or hardly protrudes beyond the height of the edge of the lid, the risk of injury to the injection needle is very low even when handling the lid with the injection needle. Furthermore, to draw liquid from the refill bottle into the chamber, the refill bottle must be held overhead so that the end of the injection needle is immersed in the liquid. The result of this is that foam in the liquid floats far away from the needle on the liquid level then pointing to the bottom, so that no foam is sucked in with the needle. In addition, it is possible with such an embodiment to consume almost all of the liquid in the refill bottle by suction.
Die nicht mehr anzusaugende Restmenge in der Nachfüllflasche ist ganz besonders gering, wenn gemäß einer anderen Weiterbildung der Erfindung im Flaschenhals ein einen Durchlaß für die Injektionsnadel aufweisender Einsatz angeordnet ist.The residual amount in the refill bottle that is no longer to be sucked in is particularly low if, according to another development of the invention, an insert having a passage for the injection needle is arranged in the bottle neck.
Ebenfalls zur Verminderung der nicht mehr anzusaugenden Restmenge trägt es bei, wenn die Nachfüllflasche über ihre Höhe sich im Querschnitt zum Flaschenhals hin verjüngt.It also helps to reduce the amount that can no longer be sucked in if the refill bottle tapers over its height in cross-section towards the bottle neck.
Der Deckel erleichtert das Zentrieren der Injektionsnadel auf dem Gehäuse des Filzschreibers und fixiert die Kammer beim Nachfüllen auf dem Gehäuse, wenn gemäß einer anderen Weiterbildung der Neuerung der Deckel im Querschnitt zum Aufsetzen auf das Gehäuse eines Filzschreibers während des Nachfüllvorganges ausgebildet ist.The cover facilitates the centering of the injection needle on the housing of the felt-tip pen and fixes the chamber on the housing when refilling, if, according to another development of the innovation, the cross-section of the cover is designed to be placed on the housing of a felt-tip pen during the refilling process.
Wenn die Injektionsnadel beim Nachfüllen bis in den Tampon des Filzschreibers reicht, dann kann man die Flüssigkeit nur relativ langsam aus der Kammer drücken, weil der Tampon dem Austritt der Flüssigkeit beträchtlichen Widerstand entgegensetzt. Die Übergabe der Flüssigkeit kann ganz besonders rasch erfolgen, wenn die Injektionsnadel in ihrer Länge so bemessen ist, daß sie nach dem Durchstechen des Filzschreibers nur bis in einen freien Raum oberhalb des Tampons des Filzschreibers reicht.If the injection needle reaches the tampon of the felt-tip pen during refilling, the liquid can only be pushed out of the chamber relatively slowly, because the tampon offers considerable resistance to the liquid escaping. The transfer of the liquid can take place very quickly if the length of the injection needle is such that, after the pen has been pierced, it only extends into a free space above the pad of the felt pen.

Die Figur 1 zeigt perspektivisch einen Filzschreiber 1, der ein zylindrisches Gehäuse 2 mit einem Deckel 3 hat. Nach unten hin ragt aus dem Gehäuse 2 eine Faserspitze 4, welche zum Schreiben Tusche von einem mit Tusche durchtränkten, innerhalb des Gehäuses 2 angeordneten Tampon 5 erhält. Im Deckel 3 des Gehäuses 1 ist ein Einsatz 6 aus einem elastischen Material, vorzugsweise Gummi, angeordnet.FIG. 1 shows a
Zum Nachfüllen des Filzschreibers 1 dient eine Nachfüllvorrichtung 7, welche im wesentlichen aus einem ballartigen, elastischen Hohlkörper 8 mit einer Kammer 9 und einer Injektionsnadel 10 besteht. Das Volumen dieser Kammer 9 ist so bemessen, daß in ihr gerade diejenige Menge Tusche vorhanden sein kann, welche zum Durchtränken des Tampons 5 benötigt wird.A
Zum Auffüllen des Filzschreibers 1 durchsticht man mit der Injektionsnadel 10 den Einsatz 15 und drückt dann den ballartigen Körper zusammen, so daß die Tusche aus der Kammer 9 in den Filzschreiber 1 gelangt. Dann zieht man die Nachfüllvorrichtung 7 wieder zurück. Durch die Elastizität des Einsatzes 6 verschließt sich das Loch im Einsatz 6 von selbst, sobald die Injektionsnadel 10 aus ihm heraus gelangt.To fill the felt-
Die Figur 2 zeigt eine Nachfüllflasche 12, welche von einem Boden 16 bis zu ihrem Flaschenhals 13 im Querschnitt sich gleichmäßig verjüngt. Auf den Flaschenhals 13 ist von oben her ein Deckel 11 aufschraubbar, wozu der Deckel 11 ein Innengewinde 17 und der Flaschenhals 13 ein Außengewinde 18 hat.FIG. 2 shows a
Der Deckel 11 hat an seinem oberen Ende außenseitig eine als elastischer Ball ausgebildete Kammer 9, welche mit der koaxial im Deckel 11 angeordneten Injektionsnadel 10 Verbindung hat. Diese Injektionsnadel 10 ist nur so lang, daß sie bei auf der Nachfüllflasche 12 aufgeschraubtem Deckel 11 soeben in den Flaschenhals 13 ragt. Dabei kann im Flaschenhals 13 ein Einsatz 15 mit einem Durchlaß 14 für die Injektionsnadel 10 dafür sorgen, daß bei überkopf gehaltener Nachfüllflasche 12 nahezu ihr gesamtes Flüssigkeitsvolumen mit der Injektionsnadel 10 angesaugt werden kann.The
Zum Nachfüllen eines Filzschreibers 1 hält man die dargestellte Nachfüllflasche 12 bei aufgeschraubtem Deckel 11 zunächst überkopf. Dann drückt man mit zwei Fingern die als elastischer Ball ausgebildete Kammer 9 zusammen, wodurch die in ihr befindliche Luft in die Nachfüllflasche 12 gelangt. Beim Loslassen der Kammer 9 nimmt diese ihre ursprüngliche Form wieder an und saugt sich dabei mit Flüssigkeit voll.To refill a felt-
Nach dem Füllen der Kammer 9 schraubt man den Deckel 11 von der Nachfüllflasche 12 ab und sticht seine Injektionsnadel 10 durch den dafür vorgesehenen Bereich in der oberen Stirnfläche des Filzschreibers 1, bis sich der Deckel 11 auf das Gehäuse 2 des Filzschreibers 1 aufsetzt. Die Injektionsnadel 10 ist hinsichtlich ihrer Länge so bemessen, daß sie dann nur bis in einen Raum oberhalb des Tampons 5 des Filzschreibers 1 gelangt. Das ermöglicht es, durch Drücken auf die als elastischer Ball ausgebildete Kammer 9 rasch die in ihr vorhandene Flüssigkeit in den Filzschreiber 1 zu überführen, da kein hoher Strömungswiderstand zu überwinden ist.After the chamber 9 has been filled, the
Das Volumen der Kammer 9 kann so bemessen werden, daß es genau der erforderlichen Flüssigkeitsmenge für einen üblichen Filzschreiber entspricht. Für dickere Filzschreiber muß man dann den Nachfüllvorgang zweimal durchführen. Unabhängig von der Größe der Kammer 9 ist jedoch mit der neuerungsgemäßen Nachfüllflasche 12 ein präzises Dosieren des erforderlichen Nachfüllvolumens möglich, was vor allem dann wichtig ist, wenn ein Filzschreiber beim Nachfüllen nicht vollständig leer ist, so daß eine nicht genau zu bestimmende Flüssigkeitsmenge nachgefüllt werden muß.The volume of the chamber 9 can be dimensioned so that it corresponds exactly to the amount of liquid required for a conventional felt-tip pen. For thicker felt pens, the refill process must be carried out twice. Regardless of the size of the chamber 9, however, the
