Description

Die Erfindung betrifft ein Schreibgerät mit einer Abgabevorrichtung für Schreibgeräte am vorderen Ende und einem Flüssigkeitsreservoir am hinteren Ende.The invention relates to a writing instrument with a dispensing device for writing instruments at the front end and a fluid reservoir at the rear end.

Mit flüssiger Tinte oder flüssiger Farblösung betriebene Schreibgeräte, wie z.B. Schreib-, Mal-, Zeichen- oder Markiergeräte bestehen üblicherweise aus einem Flüssigkeitsreservoir zur Aufnahme der Tinte oder Farbstofflösung und einer Tintenabgabevorrichtung, über die die Tinte beim Schreiben nach und nach abgegeben wird. Beliebt beim Verbraucher sind solche Stifte, bei denen der Tintenvorrat erkennbar ist. Diese werden als "free ink-Systeme" bezeichnet. Um die Menge an noch vorhandener Tinte erkennen zu können, besteht bei derartigen Schreibgeräten zumindest ein Teil des Flüssigkeitsreservoirs aus einem transparenten Kunststoff. Wenn besonders hohe Anforderungen an die Transparenz gestellt werden, sind Polyester, Polyamid oder Polystyrol mögliche Materialien. Es werden jedoch aufgrund der hervorragenden mechanischen Eigenschaften zunehmend auch transparente Typen von Polyolefinen verwendet, insbesondere Polypropylen. Polypropylen ist hydrophob und stößt hydrophile Flüssigkeiten ab. Wenn daher eine wäßrige Tinte verwendet wird, die in der Regel eine relativ hohe Oberflächenspannung besitzt, reißt ein sich auf den Wänden des Reservoirs bildender Tintenfilm wenigstens teilweise auf, so daß die Füllhöhe gut sichtbar wird. Wenn aber Schreibflüssigkeiten eingesetzt werden, deren Oberflächenspannung niedrig ist, z.B. Tinten auf Lösungsmittelbasis oder wäßrige Schreibflüssigkeiten, die Emulgatoren enthalten, so bleibt an den Wänden des Flüssigkeitsreservoirs ein Film haften und läßt ein Erkennen der Füllhöhe gar nicht oder nur schwierig oder nach längerer Zeit zu. Besonders gravierend ist dieses Problem, wenn eine Tinte auf Basis eines lipophilen Lösungsmittels in Kombination mit einem lipophilen Kunststoff verwendet wird,Writing instruments operated with liquid ink or liquid color solution, e.g. Typing, painting, drawing or marking devices usually consist of one Liquid reservoir for holding the ink or dye solution and one Ink dispenser over which the ink gradually writes as it is written is delivered. Pens are popular with consumers, for whom the Ink supply is recognizable. These are called "free ink systems". Around To be able to recognize the amount of ink still present exists in such Writing instruments at least part of the liquid reservoir from one transparent plastic. If particularly high demands on the Polyester, polyamide or polystyrene are possible Materials. However, it is due to the excellent mechanical Properties increasingly used transparent types of polyolefins, especially polypropylene. Polypropylene is hydrophobic and repels hydrophilic Liquids. Therefore, if an aqueous ink is used, which in the Usually has a relatively high surface tension, tears itself on the Walls of the reservoir-forming ink film at least partially, so that the Level is clearly visible. But if writing fluids are used, whose surface tension is low, e.g. Solvent based inks or aqueous writing liquids containing emulsifiers remain on the A film adheres to the walls of the liquid reservoir and allows recognition of the Fill level not at all or only with difficulty or after a long time. Especially This problem is serious when an ink based on a lipophilic Solvent is used in combination with a lipophilic plastic,

Um diese Probleme zu lösen, wurde bereits vorgeschlagen, die Innenseite eines Flüssigkeitsreservoirs mit geeigneten Kohlenwasserstoffen zu beschichten. Dieses Verfahren ist jedoch bestenfalls geeignet, wenn emulgatorfreie wäßrige Tinten verwendet wird. Für Schreibflüssigkeiten auf Lösungsmittelbasis ist es ungeeignet, da sich die Kohlenwasserstoffbeschichtung teilweise oder vollständig löst. Dadurch wird die Beschichtung entfernt und unter Umständen die Schreibflüssigkeit verändert. Beides ist unerwünscht.In order to solve these problems, it has already been suggested the inside of a Coating liquid reservoirs with suitable hydrocarbons. However, this method is best suited if the emulsifier-free aqueous solution Inks is used. It is for solvent-based writing fluids unsuitable because the hydrocarbon coating is partially or completely solves. This will remove the coating and possibly the Writing fluid changed. Both are undesirable.

Aufgabe der Erfindung war es daher, ein Schreibgerät bereitzustellen, bei dem der Füllstand der Schreibflüssigkeit leicht und schnell erkennbar ist. Darüber hinaus war es Aufgabe der Erfindung, eine Beschichtung für ein Flüssigkeitreservoir bereitzustellen, so daß ein an der Oberfläche haftender Flüssigkeitsfilm rasch von der Wandung wieder abläuft, wobei diese Beschichtung dauerhaft ihre Wirkung ausüben muß und die Schreibflüssigkeit nicht nachteilig verändern darf.The object of the invention was therefore to provide a writing instrument in which the level of the writing fluid is easily and quickly recognizable. About that it was also an object of the invention to provide a coating for a liquid reservoir To be provided so that a liquid film adhering to the surface quickly runs off the wall again, this coating permanently Must have an effect and must not adversely change the writing fluid.

Diese Aufgaben werden gelöst mit einem Schreibgerät mit einer Abgabevorrichtung für Schreibflüssigkeit am vorderen Ende und einem zumindest teilweise einsehbaren Flüssigkeitsreservoir am hinteren Ende, das dadurch gekennzeichnet ist, daß das Reservoir innen zumindest teilweise mit einer Silikonkautschukschicht ausgekleidet ist.These tasks are solved with a writing instrument with a dispensing device for writing fluid at the front end and at least partially visible liquid reservoir at the rear end, which is characterized is that the reservoir at least partially with a silicone rubber layer is lined.

Es wurde gefunden, daß bei Verwendung eines vernetzten Silikonkautschuks, der in dünner Schicht auf die Innenwand des Flüssigkeitsreservoirs aufgetragen wird, Farbstofflüssigkeit oder Tintenflüssigkeit schnell an der Wand des Flüssigkeitsbehälters abläuft. Auf diese Weise ist der verfügbare Schreibflüssigkeitsvorrat jederzeit leicht einsehbar. It has been found that when using a cross-linked silicone rubber, which is applied in a thin layer to the inner wall of the liquid reservoir , dye liquid or ink liquid quickly on the wall of the liquid container expires. In this way, the available writing fluid supply easily visible at all times.

Erfindungsgemäß wird ein Schreibgerät zur Verfügung gestellt, dessen vorderer Teil eine Abgabevorrichtung für Schreibflüssigkeit aufweist, die in an sich bekannterweise zur Abgabe von Tinte beim Schreiben ausgebildet ist. Den hinteren Teil des Schreibgerätes bildet ein Flüssigkeitsreservoir zur Aufnahme der Schreibflüssigkeit. Das Reservoir ist zumindest teilweise transparent. Es kann z.B. im Bereich der Griffzone undurchsichtig sein und kann außerdem in üblicher Weise mit einem Aufdruck versehen sein, so daß es nicht an allen Stellen einsehbar ist. In der Regel besteht das Flüssigkeitsreservoir aus einem Kunststoff, wobei die Verwendung von Polypropylen bevorzugt ist. Als Schreibgerät wird erfindungsgemäß jedes Schreib-, Mal-, Zeichen- oder Markiergerät angesehen, das mit Schreibflüssigkeit, insbesondere flüssiger Tinte betrieben wird. Als Beispiele können mit einer bunten Markierungsflüssigkeit versehene Markierstifte oder in vielen Farben erhältliche Tintenkugelschreiber genannt werden.According to the invention, a writing instrument is provided, the front one Part has a dispenser for writing fluid, which in itself is known to be designed for dispensing ink when writing. The back one Part of the writing instrument forms a liquid reservoir for receiving the Writing fluid. The reservoir is at least partially transparent. It can e.g. be opaque in the area of the grip zone and can also be more common Way with an imprint so that it is not visible in all places is. As a rule, the liquid reservoir consists of a plastic, the use of polypropylene is preferred. As a writing instrument viewed according to the invention any writing, painting, drawing or marking device, which is operated with writing fluid, especially liquid ink. As Examples can be colored pencils with colored markers or ink pens available in many colors.

Um nun die dauerhafte Bildung eines Tintenfilms auf der inneren Oberfläche des Flüssigkeitsreservoirs zu verhindern, wird erfindungsgemäß die innere Oberfläche des Flüssigkeitsreservoirs zumindestens teilweise beschichtet, z.B. in dem transparenten Bereich des Reservoirs. Um die gewünschte Wirkung zu erzielen, muß die Beschichtung verschiedene Eigenschaften aufweisen. Zum einen muß sie selbst ebenfalls transparent sein, damit die Einsehbarkeit erhalten bleibt. Weiterhin muß die Beschichtung aus einem Material bestehen, das von der Schreibflüssigkeit weder gelöst wird noch die Schreibflüssigkeit in irgendeiner Weise beeinträchtigt oder die Farbe der Schreibflüssigkeit verändert. Außerdem muß das Material sich in dünner Schicht auftragen lassen und soll bevorzugt auch für emulgatorhaltige wäßrige Tinten geeignet sein.To ensure the permanent formation of an ink film on the inner surface of the According to the invention, the inner surface is used to prevent liquid reservoirs of the liquid reservoir at least partially coated, e.g. by doing transparent area of the reservoir. To achieve the desired effect the coating must have different properties. For one thing, must they themselves should also be transparent so that visibility is preserved. Furthermore, the coating must consist of a material that is of the Writing fluid is neither dissolved nor the writing fluid in any Manner impaired or changed the color of the writing fluid. Moreover the material must be applied in a thin layer and should be preferred also be suitable for aqueous inks containing emulsifiers.

Es wurde gefunden, daß alle diese Anforderungen erfüllt werden, wenn die Beschichtung aus Silikonkautschuk besteht. Erfindungsgemäß wird daher das Flüssigkeitsreservoir innen mit einer Schicht aus Silikonkautschuk versehen. Hierzu wird der Silikonkautschuk in einer dünnen Schicht innen zumindest auf die transparenten Anteile des Flüssigkeitsreservoirs aufgebracht. Bevorzugt ist die gesamte Innenseite des Flüssigkeitsreservoirs mit einer Schicht aus Silikonkautschuk versehen. Der Silikonkautschuk soll nur in einer dünnen Schicht vorgesehen werden. Wenn die Kautschukschicht zu dick ist, kommt es zu einem Ablösen der Beschichtung, so daß sie ihren Zweck nicht mehr erfüllt und die Schreibflüssigkeit nachteilig verändern kann. Ausserdem wurde gefunden, daß dann, wenn die Beschichtung zu dick ist, die Schreibflüssigkeit zwischen die Wandung der Tanks und das Beschichtungsmaterial wandert, wodurch die Transparenz verloren geht. Bevorzugt beträgt daher die Dicke der Siliconkautschukschicht 2 bis 100 µm. In diesem Bereich werden die nachteiligen Wirkungen nicht beobachtet. Besonders bevorzugt beträgt die Schichtdicke 10 bis 50 µm. Besonders bevorzugt wird als Silikonkautschuk ein durch Additions- oder durch Kondensationspolymerisation gewonnener Silikonkautschuk aufgebracht.It has been found that all of these requirements are met if the Coating made of silicone rubber. According to the invention, therefore Provide the inside of the liquid reservoir with a layer of silicone rubber. For this purpose, the silicone rubber is at least on the inside in a thin layer the transparent parts of the liquid reservoir applied. Is preferred the entire inside of the liquid reservoir with a layer of silicone rubber Mistake. The silicone rubber should only be provided in a thin layer become. If the rubber layer is too thick, you will get one Peeling off the coating so that it no longer serves its purpose and the Writing fluid can adversely change. It was also found that then if the coating is too thick, the writing fluid between the Wall of the tanks and the coating material migrates, causing the Transparency is lost. The thickness of the silicone rubber layer is therefore preferably 2 to 100 µm. In this area the disadvantageous Effects not observed. The layer thickness is particularly preferably 10 up to 50 µm. Particularly preferred as silicone rubber is an addition or silicone rubber obtained by condensation polymerization upset.

Die Beschichtung des Flüssigkeitsreservoirs kann in an sich bekannter Weise erfolgen, indem Silikonkautschuk auf die innere Wand aufgetragen wird. Hierzu kann der Silikonkautschuk in einem geeigneten Paraffinkohlenwasserstoff oder Isoparaffin dispergiert oder verflüssigt werden und dann in an sich bekannter Weise auf die Wand aufgetragen werden. Bevorzugt wird der Silikonkautschuk in situ auf der inneren Wand des Flüssigkeitsreservoirs erzeugt.The coating of the liquid reservoir can be done in a manner known per se done by applying silicone rubber to the inner wall. For this the silicone rubber can be in a suitable paraffin hydrocarbon or Isoparaffin can be dispersed or liquefied and then known per se Way to be applied to the wall. The silicone rubber is preferred in generated in situ on the inner wall of the liquid reservoir.

Hierzu werden z.B. mindestens 2 vernetzbare Silikonkomponenten in Gegenwart eines Katalysators in Kontakt gebracht und reagieren gelassen. Als Silikonkomponenten kommen hierbei für die Additionspolymerisation Mischungen aus Siloxanketten in Betracht, wobei bei der einen Komponente die Ketten endständig oder als Seitengruppen der Kette ungesättigte Alkylgruppen, insbesondere Ethengruppen aufweisen und bei der anderen Komponente die Gruppen endständig oder in der Kette Wasserstoffatome aufweisen. In Gegenwart eines Katalysators reagiert dann die ungesättigte Alkylgruppe mit dem Siliciumatom, an dem das Wasserstoffatom hängt unter Bildung einer C-Si-Bindung, wodurch die Ketten vernetzen. Bei der Kondensationspolymerisation werden Siloxanketten, die OH-Ketten tragen, mit solchen Ketten, die Alkoxygruppen tragen in Gegenwart eines Katalysators umgesetzt, wobei es zu einer Vernetzung über Si-O-Si-Bindungen kommt.For this, e.g. at least 2 crosslinkable silicone components in the presence a catalyst contacted and allowed to react. As silicone components Mixtures are sufficient for the addition polymerization Siloxane chains into consideration, the chains being terminal in one component or as side groups of the chain unsaturated alkyl groups, in particular Have ethene groups and in the other component the groups are terminal or have hydrogen atoms in the chain. In the presence of a Then the unsaturated alkyl group reacts with the silicon atom, on which the hydrogen atom is attached to form a C-Si bond, whereby network the chains. In condensation polymerization, siloxane chains, which carry OH chains, with those chains which carry alkoxy groups in The presence of a catalyst is implemented, resulting in crosslinking via Si-O-Si bonds is coming.

Die Erzeugung der Beschichtung auf der Innenwand des Reservoirs erfolgt in einer bevorzugten Ausführungsform so, daß die beiden vernetzbaren Silikonkomponenten gemischt, mit Katalysator versetzt und dann mit einer Ringdüse auf die innere Wand des Flüssigkeitsbehälters aufgesprüht werden. Die Menge an Katalysator wird hier so ausgewählt, daß die Anwendungszeit genügend lang ist, damit die Masse nicht in der Ringdüse polymerisiert und die Düse verstopft. Die entsprechenden Anteile der Komponenten sind dem Fachmann an sich bekannt und können leicht für jede spezielle Verbindung durch Routineversuche herausgefunden werden.The coating on the inner wall of the reservoir is produced in a preferred embodiment so that the two crosslinkable silicone components mixed, mixed with catalyst and then with an annular nozzle be sprayed onto the inner wall of the liquid container. The amount of catalyst is selected here so that the application time is long enough is so that the mass does not polymerize in the ring nozzle and clog the nozzle. The corresponding proportions of the components are known to the person skilled in the art known and can easily be used for any particular connection through routine experimentation be found out.

In einer anderen Ausführungsform wird die Mischung aus Silikonkomponenten und Katalysator innen im vorderen Bereich des Flüssigkeitsreservoirs aufgetragen und dann durch Zentrifugieren auf der inneren Oberfläche verteilt. Da das aufzutragende Medium eine hohe Viskosität aufweist, kann mit diesem Verfahren nicht immer ein gleichmäßig dicker Film erzielt werden. In manchen Fällen entsteht auch ein nicht zusammenhängender Film.In another embodiment, the mixture of silicone components and catalyst applied inside the front area of the liquid reservoir and then distributed on the inner surface by centrifugation. Since that Medium to be applied can have a high viscosity with this method a uniformly thick film cannot always be achieved. In some cases a non-contiguous film is also created.

In einer weiteren Ausführungsform kann das Flüssigkeitsreservoir beschichtet werden, indem die einzelnen Komponenten nacheinander als Aerosol in das Reservoir eingeblasen werden und auf der Wand ausreagieren gelassen werden. Diese Ausführungsform ist allerdings nur dann geeignet, wenn eine vollständige Beschichtung vorgesehen ist, da durch das Versprühen die Komponenten in alle Bereiche gelangen. Wenn daher die Eintrittsöffnung frei von dem Film bleiben soll, muß eine andere Ausführungsform gewählt werden. Bei dieser Ausführungsform sollten die Mischungsverhältnisse sehr genau eingehalten werden, um ein Aushärten zu erreichen und einen unlöslichen Film zu erhalten. Daher erfordert diese Methode ein hohes Maß an Präzision der Auftragsdüsen und eine sehr zuverlässige Dosierung.In a further embodiment, the liquid reservoir can be coated by adding the individual components one after the other as an aerosol into the The reservoir is blown in and allowed to react on the wall. However, this embodiment is only suitable if a complete Coating is provided because by spraying the components in all Areas. Therefore, if the entry opening remains clear of the film another embodiment must be selected. At this Embodiment should adhere to the mixing ratios very precisely to achieve curing and to obtain an insoluble film. This method therefore requires a high degree of precision in the application nozzles and a very reliable dosage.

Als besonders vorteilhaft hat sich die folgende Ausführungsform erwiesen. Hier werden die Einzelkomponenten in einem Lösungsmittel, bevorzugt einem flüchtigen organischen Lösungsmittel, gelöst und die geeignete Menge an Reaktionskatalysator zugesetzt. Dann wird diese Lösung in das Flüssigkeitsreservoir bis zur gewünschten Höhe eingefüllt und dann sofort wieder heraus gesaugt. Sobald die Reste des Lösungsmittels verdampft sind, bleibt ein gleichmäßiger Polymerfilm auf der Wandung zurück. Durch geeignete Dosierung des Katalysators läßt sich die Reaktionszeit und damit die mögliche Nutzungszeit einstellen. Mit diesem Verfahren ist es möglich, einen Film gewünschter Dicke gleichmäßig in den Bereichen des Flüssigkeitsreservoirs, die hierfür vorgesehen sind, aufzutragen. Als besonders geeignetes Lösungsmittel, hat sich Petrolether erwiesen. Andere Lösungsmittel, die die Silikonkomponenten lösen, sind jedoch ebenfalls geeignet. Nicht geeignet, sind solche Lösungsmittel, die den Kunststoff des Flüssigkeitsreservoirs anlösen.The following embodiment has proven to be particularly advantageous. Here the individual components in a solvent, preferably a volatile organic solvent, dissolved and the appropriate amount of reaction catalyst added. Then this solution is put up in the liquid reservoir filled to the desired height and then immediately sucked out again. As soon as the residues of the solvent have evaporated, a uniform polymer film remains back on the wall. By suitable dosing of the catalyst the response time and thus the possible time of use arise. With With this method it is possible to evenly film a desired thickness the areas of the liquid reservoir intended for this purpose. Petroleum ether has proven to be a particularly suitable solvent. However, other solvents that dissolve the silicone components are also suitable. Not suitable are those solvents that the plastic of the Dissolve liquid reservoirs.

Erfindungsgemäß wird ein Schreibgerät bereitgestellt, dessen Flüssigkeitsreservoir so beschichtet ist, daß eine Haftung der Schreibflüssigkeit an der Oberfläche verhindert oder zumindest stark minimiert wird und die gleichzeitig gegenüber der Schreibflüssigkeit inert ist. Hierdurch wird erreicht, daß die Schreibflüssigkeit jederzeit von dem beschichteten Teil der Wandung des Flüssigkeitsreservoirs abperlt und damit die Füllstandshöhe jederzeit gut erkennbar ist.According to the invention, a writing instrument is provided, whose liquid reservoir is coated so that the writing fluid adheres to the surface is prevented or at least greatly minimized and at the same time opposite the writing fluid is inert. This ensures that the writing fluid at any time from the coated part of the wall of the liquid reservoir rolls off and the level can be easily recognized at any time.
