Un capuchon pour instruments d'écriture, notamment pour stylos à bille, comporte au moins un canal d'air (4) qui traverse la face frontale (2). Ce canal d'air est disposé axialement et radialement et se trouve dans la région de la face frontale fermée par ailleurs. Les sections (4') disposées axialement du canal d'air sont délimitées par au moins une paroi transversale d'impact (5) ou bien par au moins un étagement (5'') ou un disque (5') et sont reliées par l'intermédiaire d'au moins une ouverture radiale (4''') avec d'autres sections axiales en quinconce (4'') ou avec l'intérieur (7) du capuchon (1'') pour former des canaux d'air traversants. En outre, la paroi du capuchon, la paroi frontale et la paroi d'impact ou bien le ou les étagements ou encore le ou les disques sont solidaires les uns des autres.A cap for writing instruments, in particular for ballpoint pens, has at least one air channel (4) which passes through the front face (2). This air channel is disposed axially and radially and is located in the region of the front face which is also closed. The sections (4 ') arranged axially of the air channel are delimited by at least one transverse impact wall (5) or else by at least one step (5' ') or a disc (5') and are connected by through at least one radial opening (4 '' ') with other staggered axial sections (4' ') or with the inside (7) of the cap (1' ') to form channels of through air. In addition, the wall of the cap, the front wall and the impact wall or else the tier or shelves or the disc (s) are integral with each other.

Description

Kappe für Schreibgeräte Cap for writing instruments
Beschreibungdescription
Die Erfindung betrifft eine Kappe für Schreibgeräte, insbesondere für Kugelschreiber, aber auch für andere Schreib-, Zeichen- oder Malgeräte, wobei die Kappe mindestens einen die Stirnseite durchdringenden Luftkanal aufweist.The invention relates to a cap for writing instruments, in particular for ballpoint pens, but also for other writing, drawing or painting instruments, the cap having at least one air channel penetrating the end face.
Derartige Kappen sind aus EP-OS 204 252 (AI) bekannc. Diese bekannten Kappen bestehen aber stets aus mehreren eingesetzten und/oder axial gegeneinander beweglichen Teilen und sind daher stets teuer und meist kompliziert herstellbar.Such caps are known from EP-OS 204 252 (AI). However, these known caps always consist of several inserted and / or axially movable parts and are therefore always expensive and usually complicated to manufacture.
Darüberhinaus gewährleisten diese bekannten Kappen keine sichere, ständig vorhandene Luftzirkulation, wenn die Kappe vom Schreib-, Zeichen- oder Malgerät getrenne wird. Insbesondere durch die axial bewegüche Innendichtung kann und soll der Luftkanal in der Stirnwand verschlossen werden.In addition, these known caps do not ensure safe, permanent air circulation when the cap is separated from the writing, drawing or painting device. The air duct in the front wall can and should be closed, in particular by the axially movable inner seal.
Aufgabe der Erfindung ist es daher, eine einfache und preiswert herstellbare Kappe für Schreibgeräte aller Art zu schaffen, die sowohl vor Verschmutzung der Kleidung, als auch vor Beschädigung der Schreibspitze sicher schützt und die dennoch durchgehende Luftzirkulation ermöglicht, wenn sie nicht mit dem Schreibgerät verbunden ist.The object of the invention is therefore to provide a simple and inexpensive to produce cap for writing utensils of all kinds, which reliably protects both against soiling of clothing and against damage to the writing tip and which nevertheless enables continuous air circulation when it is not connected to the writing instrument .
Diese Aufgabe wird mit den im Anspruch 1 umfaßten Merkmalen gelöst.This object is achieved with the features included in claim 1.
Vorteilhafte Ausgestaltungen und Weiterbildungen sind in den ergänzenden Ansprüchen dargestellt. Anhand einiger beispielhafter Darstellungen wird die Erfindung mit Hilfe der Abbildungen näher erläutert. Hierbei zeigt :Advantageous refinements and developments are presented in the additional claims. The invention is explained in more detail with the aid of the figures, using some exemplary representations. Here shows:

Fig. 6 eine Draufsicht der Kappe gem. Fig. 4 und 5 undFig. 6 is a plan view of the cap acc. 4 and 5 and
Fig. 7 eine dritte Variante mit integrierter Innendichtung in Schnittdarstellung.Fig. 7 shows a third variant with integrated inner seal in a sectional view.
Die in den Figuren 1 bis 3 dargestellte Kappe 1 ist insgesamt einstückig ausgebildet und weist einen angeformten Klipp 10 auf. Die geschlossene Stirnseite 2 ist mit zwei halbrunden, die Stirnwand 3 durchbrechenden, axial verlaufenden Abschnitten 4' eines durchgehenden Luftkanals 4 , versehen. Hierbei bildet sich gleichzeitig eine von Stegen gehaltene Scheibe 5' als von innen wirkende Prallwand 5. Über radiale Öffnungen 4''' und einen weiteren axialen Abschnitt 4'' wird der Luftkanal 4 durchgehend und mündet in den Innenraum 7 der Kappe 1.The cap 1 shown in FIGS. 1 to 3 is formed in one piece overall and has an integrally formed clip 10. The closed end face 2 is provided with two semicircular, axially extending sections 4 ′ of a continuous air duct 4 that break through the end wall 3. At the same time, a disk 5 'held by webs forms as an impact wall 5 acting from the inside. Via radial openings 4' '' and a further axial section 4 '', the air duct 4 becomes continuous and opens into the interior 7 of the cap 1.
Eine als quer verlaufende Prallwand 5 dienende ringförmig umlaufende Stufe 5'' bewirkt hierbei eine Umlenkung des Luftstroms sowie einen sicheren Schutz der - hier eine Schreibkugel 12 enthaltenden - Schreibspitze 11 vor Beschädigung durch axial in die Kappe 1 eindringenden Fremdkörpern. Außerdem wird dadurch verhindert, daß z. B. Stoffteile eines Kleidungsstückes weit in die Kappe eindringen und mit der Schreibspitze 11 bzw. der Schreibkugel 12 in Kontakt kommen können und verschmutzen.A ring-shaped circumferential step 5 ″ serving as a transverse baffle 5 in this case causes a deflection of the air flow and reliable protection of the writing tip 11 — which here contains a writing ball 12 — from damage by foreign bodies penetrating axially into the cap 1. It also prevents z. B. fabric parts of a garment penetrate far into the cap and can come into contact with the writing tip 11 or writing ball 12 and contaminate them.
Mittels eines an der Kappenwand 8 angeformten Ringwulstes 15 sind der Schaft 14 des Schreibgerätes und die Kappe 4 formschlüssig oder reibschlüssig fest, aber axial lösbar, miteinander verbunden.By means of an annular bead 15 formed on the cap wall 8, the shaft 14 of the writing instrument and the cap 4 are connected to one another in a form-fitting or friction-locked manner, but axially releasably.
Die im wesentlichen axial und radial versetzten axialen Abschnitte 4' und 4'' des Luftkanals 4 und die axial angrenzenden, als Prallwände 5 dienenden Stufen 5'' und/oder Scheiben 5' sind in vorteilhafter Weise derart gestaltet, daß sie im wesentlichen jeweils gleichen oder annähernd gleichen Querschnitt aufweisen. Dies erleichtert bzw. ermöglicht die in axialer Richtung erfolgende Entformung der in der Regel aus thermoplastischem Kunststoff im Spritzgießverfahren hergestellten Kappen. Zur Befestigung bzw. Sicherung der als Prallwänce 5 dienenden Scheiben 5' sind diese über radial und ggf. auch axial verlaufende Stege 6 mit der Stirnwand 3 und/oder der Kappenwand 8 verbunden.The substantially axially and radially offset axial sections 4 'and 4' 'of the air duct 4 and the axially adjacent steps 5' 'and / or disks 5' serving as baffle walls 5 are advantageously designed such that they are essentially the same or have approximately the same cross section. This facilitates or enables the axial demolding of the caps, which are generally made of thermoplastic material by injection molding. To secure or secure the washers 5 'serving as impact walls 5', these are connected to the end wall 3 and / or the cap wall 8 via radial and possibly also axially extending webs 6.
Bei der Ausführung nach den Figuren 4 bis 6 durchdringt ein erster koaxial zum Innenraum 7 der Kappe 1' angeordneter, axial verlaufender Abschnitt 4' eines Luftkanals 4 , die Stirnwand 3 von der Stirnseite 2 her. über radiale Öffnungen 4''' und weitere axiale Abschnitte 4'' entsteht hierbei ein durchgehender Luftkanal 4 . Die einen Klipp 10 aufweisende Kappe 1' ist auf den Schaft 14 eines ebenfalls mit einer Schreibkugel 12 versehenen Schreibgerätes aufgesteckt. Zur axialen Abdeckung der Schreibspitze 11 dient hierbei eine alsIn the embodiment according to FIGS. 4 to 6, a first axially extending section 4 'of an air duct 4 arranged coaxially to the interior 7 of the cap 1' penetrates the end wall 3 from the end face 2. A continuous air channel 4 is created via radial openings 4 ″ ″ and further axial sections 4 ″. The cap 1 ', which has a clip 10, is fitted onto the shaft 14 of a writing instrument likewise provided with a writing ball 12. For the axial covering of the writing tip 11, one is used as
Prallwand 5 gestaltete runde Scheibe 5', die praktisch gleichen Querschnitt bzw. gleichen Durchmesser aufweist, wie der axial anschließende Abschnitt 4' des Luftkanals 4 Diese Scheibe 5' ist durch Stege 6 mit der Kappenwand 8 bzw. mit der Stirnwand 3 fest verbunden bzw. an diese einstückig angeformt. Die Anzahl der Stege 6 kann beliebig gewählt werden. Vorteilhaft und ausreichend sind beispielsweise zwei, drei oder auch vier Stege.Baffle 5 designed round disc 5 ', which has practically the same cross-section or the same diameter, like the axially adjoining section 4 'of the air duct 4. This disk 5' is firmly connected by webs 6 to the cap wall 8 or to the end wall 3 or is integrally formed thereon. The number of webs 6 can be chosen arbitrarily. For example, two, three or even four webs are advantageous and sufficient.
Gemäß Figur 7 ist die, im Prinzip wie in Fig. 4 bis 6 gezeigt und beschriebene, Kappe 1'' einem Schreib-, Zeichen- oder Malgerät mit einer Dochtspitze 13 zugeordnet und mit einer zusätzlichen Dichtung 9 versehen. Dadurch werden die Dochtspitze 13 und eventuell im Bereich der Schreibspitze 11'' vorhandene Luftöffnungen des Schreibgerätes in Verschlußposition, d. h., bei auf den Schaft 14 aufgeschobener und mit dem Ringwulst 15 formschlüssig gehaltener Montageposition, luftdicht abgeschlossen.According to FIG. 7, the cap 1 ″, in principle as shown and described in FIGS. 4 to 6, is assigned to a writing, drawing or painting device with a wick tip 13 and is provided with an additional seal 9. Characterized the wick tip 13 and possibly existing in the area of the writing tip 11 '' air openings of the writing instrument in the closed position, i. that is, airtight when the mounting position is pushed onto the shaft 14 and held positively with the annular bead 15.
Andererseits kann aber bei gelöster Kappe 1'' bzw. auch bereits beim Lösen der Kappe Außenluft über die Abschnitte 4', 4''' und 4'' in den Innenraum 7 eintreten. Die Dichtung 9 ist hier topfförmig gestaltet und an die Prallwand 5 bzw. an die durch Stege 6 gehaltene Scheibe 5' einstückig angeformt. Alternativ kann aber auch jede andere Dichtungsform und -art gewählt werden. So kann z. 3. auch ein Schaum- bzw. Moosgummikissen oder eine Silikon-Auf- oder -Einlage als Dichtung 9 in Betracht kommen.On the other hand, when the cap 1 ″ is released or even when the cap is released, outside air can enter the interior 7 via the sections 4 ′, 4 ″ ″ and 4 ″. The seal 9 is cup-shaped here and integrally formed on the baffle 5 or on the disc 5 'held by webs 6'. Alternatively, any other seal shape and type can be selected. So z. 3. a foam or foam rubber cushion or a silicone overlay or insert can also be used as the seal 9.
Besonders bei dieser Ausführung nach Fig. 7 ergibt sich neben den aufgabengemäßen Wirkungen ergänzend der Vorteil, daß auch bei dichtend wirkenden Kappen und ähnlichen Verschlüssen sowohl beim Aufstecken auf das Schreib-, Zeichen- oder Malgerät, als auch beim Lösen von diesem, keinerlei Kompressionsbildung einerseits oder Unterdruckbildung zum anderen, entsteht und daß auch dadurch die Auslauffestigkeit derartiger Schreibgeräte zusätzlich erhöht wird.In particular, in this embodiment according to FIG. 7, in addition to the effects according to the task, there is the additional advantage that, even with sealing caps and similar closures, when plugging onto the writing, drawing or painting device, as well as when detaching from it, no compression is formed on the one hand or The formation of negative pressure on the other hand arises and that the leakage resistance of such writing instruments is also increased thereby.
Die Ermöglichung einer axial von innen und von außen durchgehenden Luftzirkulation durch die Kappe 1, 1', 1'', wenn diese nicht mit dem Schreib-, Zeichen- oder Malgerät verbunden ist, soll insbesondere der Sicherheit von Kindern oder sonstigen Personen dienen, um bei eventuellem Verschlucken einer derartigen Kappe die Erstickungsgefahr zu verringern.The ability of the cap 1, 1 ', 1' 'to allow air to flow axially from the inside and outside, if it is not connected to the writing, drawing or painting device, is intended in particular to ensure the safety of children or other people reduce the risk of suffocation if such a cap is swallowed.
Unter diesem Aspekt ist zudem besonders darauf zu achten, daß der Querschnitt des Luftkanales 4 bzw. dessen kleinster Abschnitt 4', 4''', 4''', mindestens 5 bis 15 mm2, vorzugsweise 7 bis 10 mm2, beträgt, damit stets ausreichend viel Luft hindurchströmen kann.From this point of view, special care must also be taken to ensure that the cross section of the air duct 4 or its smallest section 4 ', 4''', 4 '''is at least 5 to 15 mm 2 , preferably 7 to 10 mm 2 , so that sufficient air can always flow through.
Die sichere Verbindung zwischen Schaft 14 und Kappe 1" wird bei diesen Variantenmittels einer Ringnut 16 im Schaft 14 und einem Ringwulst 15 an der Kappe 1" erzielt.In these variants, the secure connection between the shaft 14 and the cap 1 "is achieved by means of an annular groove 16 in the shaft 14 and an annular bead 15 on the cap 1".
Neben dem Schutz der Schreibspitze 11, 11' bietet die vertieft liegende Scheibe 5' auch die Möglichkeit, der geschützten Anordnung einer Produkt-, Firmenoder sonstigen Kennzeichnung in vorteilhafter Weise. Ein Verwischen oder Beschädigen einer dort angebrachten Markierung ist praktisch nicht möglich.
