Abstract

A writing instrument having a closure cap assembly (1, 2, 3, 4 and 5) which can be placed in a sealing manner on the writing tip (20), whereby a positive engagement with an indentation in the writing tip is established via an elastically deformable finger (8), when the closure cap is in place on the writing tip. On the inner face of the arm (8), oriented toward the writing tip (20), at least one cam face (13) is located in a chord plane of the circle forming the closure cap opening. Whereupon a twisting of the entire mounted closure cap assembly (1, 2, 3, 4 and 5) brings the cam face (13) into engagement with a correspondingly formed wedge face (27) of the writing tip (20), so that the arm (8) is pivoted radially outward, and the closure cap can be removed.

Description

Die Erfindung. bezieht sich auf ein Schreibgerät mit einer die Schreibspitze dichtend verschließenden, abnehmbaren Verschlußkappe, die an ihrer Einsteckseite mindestens einen sich im wesentlichen axial erstreckenden, elastisch verformbaren Finger aufweist, der bei aufgesteckter Verschlußkappe in Eingriff mit einer Vertiefung im Schaft oder in der Schreibspitze steht, wobei eine sich in der Verschlußkappe befindende Ringschulter des Schreibgerätes in dichtendem Eingriff mit einer Dichtschulter der Verschlußkappe steht.The invention. refers to a writing instrument with a removable closure cap sealingly sealing the writing tip, which has at least one substantially axially extending, elastically deformable finger on its insertion side, which engages with a recess in the barrel or in the writing tip when the closure cap is attached, whereby an annular shoulder of the writing instrument located in the sealing cap is in sealing engagement with a sealing shoulder of the sealing cap.

Bei einem bekannten Schreibgerät dieser Art (DE-PS 945 818) sind in der Verschlußkappe mehrere Arme in Form von Blattfedern vorhanden, und diese Blattfedern sind an ihrem der Einsteckseite der Verschlußkappe näheren Endbereich gekrümmt, so daß sie mit diesem gekrümmten Endbereich bei aufgesteckter Verschlußkappe eine Ringschulter der Schreibspitze hintergreifen. Zum Lösen der Verschlußkappe ist ein besonderer Entriegelungseinrichtung vorhanden, durch den mit Hilfe eines axial verlagerbaren Knopfes Auslöseschienen zwischen die Blattfedern und die Schreibspitze geschoben werden und so der Eingriff zwischen diesen gelöst wird. Erst nach Lösen dieses Eingriffes kann die Verschlußkappe von der Schreibspitze abgezogen werden.In a known writing instrument of this type (DE-PS 945 818), several arms in the form of leaf springs are present in the closure cap, and these leaf springs are curved on their end region closer to the insertion side of the closure cap, so that they are connected to this curved end region when the closure cap is attached Reach behind the ring shoulder of the writing tip. To release the closure cap, a special unlocking device is provided, by means of which release rails are pushed between the leaf springs and the nib with the aid of an axially displaceable button, and the engagement between them is released. Only after loosening this Intervention, the cap can be removed from the writing tip.

Eine derartige Entriegelungseinrichtung ist sowohl aufwendig in der Fertigung als auch störanfällig, weil sie gegen Federdruck bewegbare Teile aufweist.Such an unlocking device is both complex to manufacture and prone to failure because it has parts that can be moved against spring pressure.

Es ist Aufgabe der Erfindung, ein Schreibgerät zu schaffen, bei dem die auf die Schreibspitze aufgesteckte Verschlußkappe im aufgesteckten Zustand- festsitzt und so eine gute Dichtwirkung hervorruft, urid bei dem sich die Verschlußkappe ohne Zuhilfenahme einer bewegbare Teile aufweisenden Entriegelungseinrichtung abziehen läßt.It is an object of the invention to provide a writing instrument in which the closure cap attached to the writing tip is stuck in the attached state and thus produces a good sealing effect, in which the closure cap can be pulled off without the aid of an unlocking device having movable parts.

Zur Lösung dieser Aufgabe wird ein Schreibgerät der eingangs erwähnten Art erfindungsgemäß derart ausgestaltet, daß an der bei aufgesteckter Verschlußkappe der Vertiefung zugewandten Fläche des Fingers mindestens eine im wesentlichen in einer Kreissehnenebene des die Verschlußkappenöffnung bildenden Kreises liegende Nockenfläche vorgesehen ist, die durch Verdrehung der aufgesteckten Verschlußkappe in Eingriff mit einer entsprechend geformten Keilfläche am Schaft bzw. an der Schreibspitze bringbar ist. Dabei sind am Finger vorzugsweise mindestens zwei entgegengesetzt geneigte Nockenflächen vorgesehen, die im Bereich ihrer Schnittlinie den geringsten radialen Abstand von der Längsachse der Verschlußkappe haben, und die beiden Nockenflächen sind zwischen entsprechende, entgegengesetzt geneigte Keilflächen führbar.To achieve this object, a writing instrument of the type mentioned at the outset is designed in such a way that at least one cam surface is provided on the surface of the finger facing the recess when the closure cap is attached, which cam surface lies essentially in a plane of the circular chord of the circle forming the closure cap opening, which is caused by rotation of the attached closure cap can be brought into engagement with a correspondingly shaped wedge surface on the barrel or on the writing tip. At least two oppositely inclined cam surfaces are preferably provided on the finger Have the smallest radial distance from the longitudinal axis of the closure cap in the area of their cutting line, and the two cam surfaces can be guided between corresponding, oppositely inclined wedge surfaces.

Die bei dem erfindungsgemäß ausgebildeten Schreibgerät vorhandene Steckverbindung zwischen Verschlußkappe und Schreibspitze kann somit mit Hilfe des Eingriffs einer geneigten Nockenfläche mit einer entsprechend geneigten Keilfläche gelöst werden, weil durch diesen Eingriff und Verdrehung der aufgesteckten Verschlußkappe bezüglich der Schreibspitze der elastisch verformbare Finger der Verschlußkappe radial nach außen verschwenkt wird und so der die Nockenfläche aufweisende Vorsprung aus der Vertiefung im Schaft oder im Schreiberkörper freikommt. Dadurch kann dann die Verschlußkappe von der Schreibspitze abgezogen werden.The existing plug connection between the closure cap and the writing tip in the writing device designed according to the invention can thus be released with the aid of the engagement of an inclined cam surface with a correspondingly inclined wedge surface, because this engagement and rotation of the attached closure cap with respect to the writing tip of the elastically deformable fingers of the closure cap radially outward is pivoted and so the projection having the cam surface is released from the recess in the barrel or in the pen body. As a result, the closure cap can then be removed from the writing tip.

Sind in der bevorzugten Ausbildung zwei entgegengesetzt geneigte Nockenflächen und zugehörige Keilflächen vorhanden, so kann das Lösen der Verschlußkappe durch Verdrehen in beliebiger Richtung bezüglich der Schreibspitze erfolgen.If there are two oppositely inclined cam surfaces and associated wedge surfaces in the preferred embodiment, the closure cap can be loosened by rotating it in any direction with respect to the writing tip.

Um zum Lösen der Verschlußkappe eine möglichst geringe Verdrehung zu benötigen, können am Schaft bzw. an der Schreibspitze- über den gesamten Umfang verteilt entgegengesetzt geneigte Keilflächen vorgesehen werden, so daß sich auch bei verhältnismäßig geringer Verdrehung bereits ein Eingriff von Nockenfläche und Keilfläche und damit ein das Lösen der Verschlußkappe ermöglichendes Verschwenken des Arms radial nach außen ergibt.In order to require as little twisting as possible to loosen the closure cap, oppositely inclined wedge surfaces can be provided on the shaft or on the writing tip over the entire circumference, so that even with a relatively small twist there is already an engagement of the cam surface and the wedge surface and thus the release of the closure cap allows pivoting of the arm radially outwards.

Die entgegengesetzt geneigten Keilflächen können an ihrem dem vorderen Ende der Schreibspitze näheren Endbereich unter Freilassung der Keilflächenspitzen miteinander verbunden sein, so daß sich hinter dieser Verbindung die Vertiefung für den Eingriff des Fingers befindet und der Eingriff durch einen die Nockenflächen tragenden Vorsprung erfolgt. Da die Keilflächenspitzen über die Verbindungsbereiche hinausragen, erfolgt bei entsprechender Verdrehung ein Anheben der Nockenflächen über die Keilflächen hinaus, wodurch ein widerstandsfreies Abziehen der Verschlußkappe möglich wird.The oppositely inclined wedge surfaces can be connected to one another at their end region closer to the front end of the writing tip, leaving the wedge surface tips free, so that the recess for the engagement of the finger is located behind this connection and the engagement takes place by means of a projection carrying the cam surfaces. Since the wedge surface tips protrude beyond the connection areas, the cam surfaces are lifted beyond the wedge surfaces when rotated accordingly, which enables the cap to be pulled off without resistance.

Um beim Aufstecken der Verschlußkappe auf die Schreibspitze ein selbsttätiges Ausrichten von Nockenflächen und Keilflächen zu erreichen, können die der Einsteckseite der Verschlußkappe zugewandten Bereiche der Nockenflächen zur Längsachse und von der Einsteckseite zum inneren Ende radial nach innen ansteigend geneigt oder die dem vorderen Ende der Schreibspitze zugewandten Bereiche der Keilflächen zur Längsachse und vom vorderen Ende zum unteren Ende radial nach außen ansteigend geneigt sein. Infolge dieser Neigung wird der Arm beim Aufstecken der Verschlußkappe in jeder Stellung radial nach außen gedrückt und so in den Bereich der Keilflächen bewegt. In diesem Bereich erfolgt dann durch Eingriff der Keilflächen mit den Nockenflächen selbsttätig eine entsprechende Verdrehung der Verschlußkappe bezüglich der Schreibspitze, so daß der gewünschte Eingriff erzielt wird.In order to achieve an automatic alignment of cam surfaces and wedge surfaces when the closure cap is placed on the writing tip, the areas of the cam surfaces facing the insertion side of the closure cap can be used inclined radially inwards to the longitudinal axis and from the insertion side to the inner end, or the areas of the wedge surfaces facing the front end of the writing tip can be inclined radially outwards to the longitudinal axis and from the front end to the lower end. As a result of this inclination, the arm is pushed radially outwards in every position when the closure cap is fitted on, and is thus moved into the area of the wedge surfaces. In this area, a corresponding rotation of the closure cap with respect to the writing tip then takes place automatically by engagement of the wedge surfaces with the cam surfaces, so that the desired engagement is achieved.

Es sei erwähnt, daß in Zusammenhang mit der Erfindung unter "Verschlußkappe" sowohl eine übliche Aufsteckkappe als auch ein Köcherelement verstanden wird, wie es beispielsweise in einem Schreibgeräteständer verwendet wird.It should be mentioned that in connection with the invention “closure cap” is understood to mean both a conventional push-on cap and a quiver element, as is used, for example, in a writing instrument stand.

Die Erfindung wird im folgenden anhand der schematisch ein Ausführungsbeispiel zeigenden Figuren näher erläutert.

  • Figur 1 zeigt einen Schnitt durch den vorderen Teil einer Schreibspitze mit aufgesetzter Verschlußkappe.
  • Figur 2 zeigt einen Schnitt durch die den Arm und die Nockenflächen aufweisende Hülse der Verschlußkappe.
The invention is explained in more detail below with reference to the figures schematically showing an exemplary embodiment.
  • Figure 1 shows a section through the front part of a writing tip with an attached cap.
  • FIG. 2 shows a section through the sleeve of the closure cap which has the arm and the cam surfaces.

Das teilweise dargestellte Schreibgerät ist ein Röhrchenschreiber mit einer Schreibspitze 20, in deren vorderem Ende ein Schreibröhrchen 22 gehalten' ist. Eine nicht dargestellte, übliche Tuscheausgleichskammer ist von einer Hülse 21 abgedeckt, die nach vorn in Richtung auf das Schreibröhrchen 22 abgezogen werden kann, um so die Tuscheausgleichskammer zur Reinigung freizulegen.The writing instrument partially shown is a tube pen with a writing tip 20 in the front End of a writing tube 22 is held '. A conventional ink compensation chamber, not shown, is covered by a sleeve 21 which can be pulled off towards the writing tube 22 in order to expose the ink compensation chamber for cleaning.

Im Bereich hinter der Tuscheausgleichskammer und damit hinter der Hülse 21 sind am Umfang der Schreibspitze 20 Keilflächen angeordnet, von denen nur die Keilflächen 23, 24, 27, 28 bezeichnet sind. Diese Keilflächen sind eben ausgebildet, und die Keilfläche 27 steigt beispielsweise vom Schreibröhrchen 22 gesehen im Uhrzeigersinn an, d. h. ihr Abstand von der Mittelachse der Schreibspitze 20 vergrößert sich allmählich, bis die Kante 26 erreicht ist, an der die Keilfläche 27 endet und die Keilfläche 24 beginnt, die mit der gleichen Neigung wie die Keilfläche 27 an der Kante 26 beginnt und, im Uhrzeigersinn vom Schreibröhrchen 22 gesehen, ihren Abstand von der Mittelachse der Schreibspitze 20 verringert, bis der Beginn der Keilfläche 23 erreicht ist, die dann entsprechend der Keilfläche 27 ansteigt. Es sei erwähnt, daß alle Keilflächen gleiche Form und Abmessung haben. Die in Figur 1 links liegenden Endbereiche der Keilflächen, also diejenigen Endbereiche, die dem Schreibröhrchen 22 näher liegen, sind durch Stege 25, 29 miteinander verbunden, d. h. der Steg 25 verbindet die Keilflächen 23 und 24 und der Steg 29 die Keilflächen 27 und 28. Die übrigen Keilflächen sind. in gleicher Weise durch nicht bezeichnete Stege miteinander verbunden. Die Höhe der Stege ist geringer als die Spitzen der Keilflächen, die sich durch Schnitt zweier benachbarter Keilflächen ergeben und von denen die eine mit 26 bezeichnet ist.In the area behind the ink compensation chamber and thus behind the sleeve 21 20 wedge surfaces are arranged on the circumference of the writing tip, of which only the wedge surfaces 23, 24, 27, 28 are designated. These wedge surfaces are flat, and the wedge surface 27 rises clockwise, for example, as seen from the writing tube 22, that is, its distance from the central axis of the writing tip 20 increases gradually until the edge 26 is reached at which the wedge surface 27 ends and the wedge surface 24 begins, which begins with the same inclination as the wedge surface 27 at the edge 26 and, viewed clockwise from the writing tube 22, decreases its distance from the central axis of the writing tip 20 until the beginning of the wedge surface 23 is reached, which then corresponds to the wedge surface 27 increases. It should be mentioned that all wedge surfaces have the same shape and dimensions. The end regions of the wedge surfaces on the left in FIG. 1, that is to say those end regions which are closer to the writing tube 22, are connected to one another by webs 25, 29, ie the web 25 connects the wedge surfaces 23 and 24 and the web 29 the wedge surfaces 27 and 28. The remaining wedge surfaces are. connected to each other in the same way by webs not designated. The height of the webs is less than the tips of the wedge surfaces, which result from the intersection of two adjacent wedge surfaces and one of which is designated by 26.

Die Keilflächen und die Stege sind einstückig mit der Schreibspitze 20 ausgebildet.The wedge surfaces and the webs are formed in one piece with the writing tip 20.

Die Verschlußkappe hat eine vorzugsweise aus Kunststoff bestehende Hülse 1, die an ihren in den Figuren links liegenden Enden eine Nut 6 zur Aufnahme des Befestigungsendes eines Clips 6' aufweist. Der Clip wird durch einen becherförmigen Einsatz 3 und einen Einsteckknopf 2 in seiner Lage gehalten. Im Bodenbereich des Einsatzes 3 befindet sich eine elastische Dichtung 4, und auf der in Figur 1 rechts liegenden Endfläche des Einsatzes 3 ist eine elastische Ringdichtung 5 vorgesehen. Die Ringdichtung 5 dichtet bei eingesteckter Schreibspitze 20 den Ringraum zwischen Schreibspitze 20 und Hülse 21 ab, während das vordere Ende des Schreibröhrchens 22 von der Dichtung 40 verschlossen wird. Die zwischen Einsteckknopf 2 und Einsatz 3 vorgesehene Feder 16 drückt den Einsatz 3 und damit die Dichtung 4 und die Ringdichtung 5 gegen die Schreibspitze.The closure cap has a sleeve 1, preferably made of plastic, which has a groove 6 at its left end in the figures for receiving the fastening end of a clip 6 '. The clip is held in place by a cup-shaped insert 3 and a plug-in button 2. In the bottom area of the insert 3 there is an elastic seal 4 and on the end face of the insert 3 on the right in FIG. 1 an elastic ring seal 5 is provided. When the writing tip 20 is inserted, the ring seal 5 seals the annular space between the writing tip 20 and the sleeve 21, while the front end of the writing tube 22 is closed by the seal 40. The provided between the plug 2 and insert 3 spring 16 presses the Insert 3 and thus the seal 4 and the ring seal 5 against the writing tip.

In der Hülse 1 ist durch axial verlaufende Einschnitte, von denen in Figur 2 der Einschnitt 7 zu erkennen ist, während der zweite Einschnitt auf gleicher Höhe wie der Einschnitt 7 in Figur 2 verläuft und die gleiche Tiefe hat, ein elastisch verformbarer Arm 8 gebildet. Am freien Ende des Arms 8 sowie an der übrigen Wandung der Hülse 1 im Bereich der Einstecköffnung, also auf Höhe des freien Endes des Arms 8 sind Nockenflächen ausgebildet. Diese Nockenflächen sind eben und verlaufen mit gleicher Neigung wie die Keilflächen der Schreibspitze. Dabei steigt beispielsweise die Nockenfläche 9 vom linken Ende der Hülse 1 in Figur 1 gesehen im Uhrzeigersinn an und verringert ihren Abstand von der Mittelachse der Hülse 1 bis der Beginn der .Nockenfläche 10 erreicht wird, die mit gleicher Neigung ihren Abstand von der Mittelachse der Hülse 1 vergrößert. Entsprechend verringert die Nockenfläche 11 beim Übergang von der Nockenfläche 10 zur Nockenfläche 12 ihren Abstand von der Mittelachse der Hülse 1 und die Nockenfläche 12 verläuft in gleicher Weise wie die Nockenfläche 10. Die am Arm 8 erkennbare Nockenfläche 13 ist eine von zwei an diesem Arm ausgebildeten Nockenflächen. Sie verläuft an der Hülse 1 aus der Schnittebene nach hinten und verringert dabei ihren Abstand von der Mittelachse der Hülse 1, während die nicht dargestellte Nockenfläche mit entsprechender Neigung aus der Schnittebene nach vorn verläuft und ihren Abstand von der Mittelachse der Hülse 1 verringert. Die Nockenflächen liegen daher alle in Kreissehnenebenen derjenigen Kreise, die den zylindrischen Öffnungsbereich der Hülse 1 bilden.An elastically deformable arm 8 is formed in the sleeve 1 by axially extending incisions, of which the incision 7 can be seen in FIG. 2, while the second incision runs at the same height as the incision 7 in FIG. 2 and has the same depth. Cam surfaces are formed on the free end of the arm 8 and on the remaining wall of the sleeve 1 in the region of the insertion opening, that is to say at the level of the free end of the arm 8. These cam surfaces are flat and run at the same inclination as the wedge surfaces of the writing tip. For example, the cam surface 9 rises clockwise from the left end of the sleeve 1 in FIG. 1 and decreases its distance from the central axis of the sleeve 1 until the beginning of the. Cam surface 10 is reached, which has the same inclination from the central axis of the sleeve 1 enlarged. Accordingly, the cam surface 11 reduces its distance from the central axis of the sleeve 1 during the transition from the cam surface 10 to the cam surface 12 and the cam surface 12 runs in the same way as the cam surface 10. The cam surface 13 recognizable on the arm 8 is one of two formed on this arm Cam surfaces. It runs on the sleeve 1 from the sectional plane to the rear and reduces its distance from the central axis of the sleeve 1, while the cam surface, not shown, runs forward with a corresponding inclination from the sectional plane and reduces its distance from the central axis of the sleeve 1. The cam surfaces are therefore all in the chord planes of those circles which form the cylindrical opening area of the sleeve 1.

Wie bereits erwähnt, befinden sich am Arm 8 Nockenflächen, von denen nur die Nockenfläche 13 zu erkennen ist. Im übrigen Teil der Hülse 1 ist in deren Öffnungsbereich eine weitere Gruppe von Nockenflächen 9, 10, 11, 12 vorgesehen. Eine entsprechende Gruppe von Nockenflächen kann um 120 versetzt im Öffnungsbereich der Hülse 1 vorhanden sein.As already mentioned, there are 8 cam surfaces on the arm, of which only the cam surface 13 can be seen. In the remaining part of the sleeve 1, a further group of cam surfaces 9, 10, 11, 12 is provided in the opening area thereof. A corresponding group of cam surfaces can be offset by 120 in the opening area of the sleeve 1.

Wie in Figur 2 dargestellt, sind die Nockenflächen an der Öffnungseite der Hülse 1 abgeschrägt, so daß von der Öffnungsseite axial und radial nach innen verlaufende Flächenbereiche 14 und 15 gebildet sind. Beim Aufstecken der Verschlußkappe auf die Schreibspitze 20 kommen diese schrägen Flächen 14, 15 sowie die entsprechenden schrägen Flächen am Arm 8 entweder in Eingriff mit den in Figur 1 nach links vorstehenden Enden der Keilflächen oder mit den Stegen 25, 29. In jedem Fall gleiten dadurch die schrägen Flächen über die Berührungsflächen an der Schreibspitze 20 und der Arm 8 wird radial nach außen verschwenkt. Infolgedessen können die Nockenflächen 9, 10, 11, 12, 13 über die Stege 20, 29 hinweggleiten und in den Bereich der Keilflächen 23, 24, 27, 28 gelangen, die in Figur 1 rechts von den Stegen 25, 29 liegen. In dieser Stellung kommen die schrägen Nockenflächen in Eingriff mit den Keilflächen, und die Kappe wird infolge des vom elastischen Arm-8 ausgeübten Druckes und der sich dadurch ergebenden Gleitbewegung der Nockenflächen auf den Keilflächen so verdreht, daß die Keilflächen flächig auf in ihrem Bereich befindlichen Nockenfläche aufliegen. In dieser Stellung kann die Verschlußkappe nicht mehr von der Schreibspitze 20 abgezogen werden, weil die Nockenflächen bzw. die die Nockenflächen bildenden Vorsprünge die Stege zwischen den Keilflächen der Schreibspitze 20 hintergreifen.As shown in Figure 2, the cam surfaces on the opening side of the sleeve 1 are chamfered, so that axially and radially inwardly extending surface areas 14 and 15 are formed from the opening side. When the closure cap is placed on the writing tip 20, these inclined surfaces 14, 15 and the corresponding inclined surfaces on the arm 8 either come into engagement with the ends of the wedge surfaces which project to the left in FIG. 1 or with the webs 25, 29. In any case, the inclined surfaces slide over the contact surfaces on the writing tip 20 and the arm 8 is pivoted radially outwards. As a result, the cam surfaces 9, 10, 11, 12, 13 can slide over the webs 20, 29 and reach the area of the wedge surfaces 23, 24, 27, 28, which are to the right of the webs 25, 29 in FIG. In this position, the oblique cam surfaces come into engagement with the wedge surfaces, and the cap is rotated due to the pressure exerted by the elastic arm-8 and the resulting sliding movement of the cam surfaces on the wedge surfaces so that the wedge surfaces are flat on the cam surface located in their area lie on. In this position, the closure cap can no longer be removed from the writing tip 20 because the cam surfaces or the projections forming the cam surfaces engage behind the webs between the wedge surfaces of the writing tip 20.

Soll die Verschlußkappe abgenommen werden, so erfolgt eine Verdrehung von Verschlußkappe und Schreibspitze 20 relativ zueinander. Dabei gleiten die Nockenflächen der Hülse 1 auf den Keilflächen der Schreibspitze 20, und es erfolgt dadurch eine Verschwenkung des Arms 8 radial nach außen. Dieses Gleiten der Nockenflächen entlang der Keilflächen muß so lange fortgesetzt werden, bis sich die radial am weitesten innen liegenden Bereiche der Nockenflächen, also beispielsweise die Schnittkante von Nockenfläche 9 und Nockenfläche 10 (Figur 2) oberhalb der Stege 25, 29 befindet. In dieser Stellung sind die Nockenflächen bzw. die sie bildenden Vorsprünge radial weiter nach außen bewegt, als die Höhe der Stege 25 und 29. In dieser Lage wird die Verschlußkappe infolge der Elastizität der Ringdichtung 5 und der Dichtung 4 sowie der Wirkung der Feder 16 nach links (Figur 1) verlagert und kann von der Schreibspitze 20 abgenommen werden.If the closure cap is to be removed, the closure cap and the writing tip 20 are rotated relative to one another. The cam surfaces of the sleeve 1 slide on the wedge surfaces of the writing tip 20 and the arm 8 is thereby pivoted radially outwards. This sliding of the cam surfaces along the Wedge surfaces must be continued until the radially innermost regions of the cam surfaces, that is to say for example the cutting edge of cam surface 9 and cam surface 10 (FIG. 2), are above the webs 25, 29. In this position, the cam surfaces or the projections forming them are moved radially further outward than the height of the webs 25 and 29. In this position, the closure cap is reduced due to the elasticity of the ring seal 5 and the seal 4 and the action of the spring 16 on the left (FIG. 1) and can be removed from the writing tip 20.
