Description

BESCHREIBUNGDESCRIPTION Sprühkappe für einen mit einem Abgabeventil versehenen DruckbehälterSpray cap for a pressure vessel provided with a dispensing valve

Die Erfindung betrifft eine Sprühkappe für einen mit einem Abgabeventil versehenen Druckbehälter, wobei die Sprühkappe einen Kappenkörper aufweist, in dessen Inneren ein Austrittskanal angeordnet ist, dessen eines Ende mit Betätigungsmitteln zum Betätigen des Abgabeventils versehen ist und wobei Mittel zum Bewegen des Austrittskanals in Richtung auf das Abgabeventil vorgesehen sind, um das Abgabeventil über die Betätigungsmittel zu betätigen.The invention relates to a spray cap for a provided with a dispensing valve pressure vessel, wherein the spray cap has a cap body, inside which an outlet channel is arranged, one end of which is provided with actuating means for actuating the dispensing valve and wherein means for moving the outlet channel in the direction of the Dispensing valve are provided to actuate the dispensing valve via the actuating means.

Aus der DE 20 2005 020 446 U1 ist eine derartige Sprühkappe bekannt, bei der in dem Austrittskanal ein Dichtelement angeordnet ist, das den Kolbensitz bildet und die ein Kolbenelement aufweist, welches einen mit einem Kolbensitz zusammenwirkenden Kolbenkopf und mindestens ein elastisches Federbein aufweist, welches in einem sich erweiternden Kanalabschnitt des Austrittskanals angeordnet ist, wobei der Kolbenkopf gegen den Kolbensitz vorgespannt ist und durch das austretende Medium aus dem Kolbensitz gedrückt wird. Bei dieser Sprühkappe wird durch Druckausübung auf den oberen Teil der Sprühkappe das Ausgabeventil, welches an einer der Seitenflächen des Betätigungskörpers angeordnet ist, geöffnet. Bei derartigen Sprühkappen schließen die beiden Abschnitte des Austrittskanals einen rechten Winkel ein.From the DE 20 2005 020 446 U1 Such a spray cap is known in which a sealing element is arranged in the outlet channel, which forms the piston seat and which has a piston element which has a piston head cooperating with a piston head and at least one elastic strut, which is arranged in a widening channel portion of the outlet channel wherein the piston head is biased against the piston seat and is pushed out of the piston seat by the escaping medium. In this spray cap, the discharge valve, which is arranged on one of the side surfaces of the actuating body, is opened by applying pressure to the upper part of the spray cap. In such spray caps, the two sections of the outlet channel form a right angle.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Sprühkappe zu schaffen, die leichter handhabbar ist.The present invention has for its object to provide a spray cap, which is easier to handle.

Diese Aufgabe wird erfindungs gemäß dadurch gelöst, daß die Mittel zum Bewegen des Austrittskanals mindestens eine um eine senkrecht zur Achse des Abgabeventils angeordnete Achse schwenkbare Nocke und mindestens eine im wesentlichen radial an der Außenwand des Austrittskanals angeordnete Druckfläche aufweisen, auf der die Nocke unter Druckausübung abrollt, wenn sie zum Inneren des Kappenkörpers hin verschwenkt wird, wobei mindestens ein Betätigungsknopf an der Seitenfläche des Kappenkörpers vorgesehen ist, um die Nocke zu verschwenken.This object is achieved according fiction, in that the means for moving the outlet channel have at least one about a perpendicular to the axis of the dispensing valve pivotable cam and at least one substantially radially disposed on the outer wall of the outlet channel pressure surface on which the cam rolls under pressure when pivoted toward the inside of the cap body, at least one operating knob being provided on the side surface of the cap body to pivot the cam.

Diese Sprühkappe kann durch senkrecht zum Abgabeventil ausgeübten Druck betätigt werden. Dies ermöglicht es, den Daumen einerseits und den Zeigefinger andererseits des Druckbehälters anzuordnen und durch zangenförmiges Zusammendrücken beider das Abgabeventil zu betätigen. Dies ist in ergonomischer Hinsicht besser als in vertikaler Richtung das Abgabeventil mit dem Zeigefinger zu betätigen, während die anderen Finger den Druckbehälter halten. Das Abrollen der Nocke unter Druckausübung auf die Druckfläche ermöglicht ein präzises Dosieren der Produktabgabemenge.This spray cap can be actuated by pressure applied perpendicularly to the dispensing valve. This makes it possible to arrange the thumb on the one hand and the index finger on the other hand of the pressure vessel and actuate by pliers-like compression both of the dispensing valve. This is ergonomically better than to operate the dispensing valve with the index finger in the vertical direction, while the other fingers hold the pressure vessel. The rolling of the cam under pressure on the pressure surface allows a precise dosing of the product discharge amount.

Eine Weiterbildung der Erfindung besteht darin, daß jede Nocke zwei im wesentlichen parallel zueinander angeordnete Platten aufweist, die diesseits und jenseits des Austrittskanals angeordnet sind.A development of the invention is that each cam has two plates arranged substantially parallel to one another, which are arranged on both sides of the outlet channel.

Auf diese Weise wird der Druck symmetrisch zum Austrittskanal verteilt, was die Gefahr einer Blockade vermindert.In this way, the pressure is distributed symmetrically to the outlet channel, which reduces the risk of blockage.

Im Rahmen der Erfindung ist vorgesehen, daß ein Federelement vorgesehen ist, um den Austrittskanal in seine Ausgangsstellung zurückzuführen, wenn kein Druck auf die Druckfläche ausgeübt wird.In the context of the invention it is provided that a spring element is provided to return the outlet channel to its initial position when no pressure is exerted on the pressure surface.

Hierdurch wird erreicht, daß der Austrittskanal in seine Ausgangsstellung zurückkehrt, wenn kein Druck auf den Betätigungsknopf mehr ausgeübt wird.This ensures that the outlet channel returns to its initial position when no pressure is exerted on the actuating button more.

In diesem Zusammenhang ist es vorteilhaft, daß der Austrittskanal an über mindestens ein Federelement an einem Befestigungsring befestigt ist.In this context, it is advantageous that the outlet channel is attached to at least one spring element on a mounting ring.

Der Befestigungsring wird hierzu an dem Druckbehälter befestigt, beispielsweise durch Einrasten, und der Kappenkörper wird wiederum mit dem Befestigungsring verbunden, beispielsweise durch Einrasten. Der Austrittskanal wird über das Federelement, das beispielsweise mit der Druckfläche des Austrittskanals verbunden ist, mit dem Befestigungsring verbunden.For this purpose, the fastening ring is fastened to the pressure vessel, for example by latching, and the cap body is in turn connected to the fastening ring, for example by latching. The outlet channel is connected via the spring element, which is for example connected to the pressure surface of the outlet channel, with the fastening ring.

Es ist zur Erfindung gehörig, daß die Druckfläche den Austrittskanal plattformartig umgibt, wobei der senkrecht zu der Drehachse der Nocke angeordnete Bereich, auf den die Nocke Druck ausüben kann, zum Druckbehälter hin gewölbt ausgebildet ist.It is part of the invention that the pressure surface surrounds the outlet channel in a platform-like manner, wherein the region, which is arranged perpendicular to the axis of rotation of the cam and onto which the cam can exert pressure, is formed curved towards the pressure vessel.

Auf diese Weise wird erreicht, daß die Nocken auf der Druckfläche besser abrollen können. Zudem wird durch die gewölbte Form eine höhere Stabilität der Druckfläche erzielt.In this way it is achieved that the cams can roll better on the pressure surface. In addition, a higher stability of the printing surface is achieved by the curved shape.

Es ist vorteilhaft, daß der Befestigungsring Lager zur schwenkbaren Lagerung der Nocken aufweist.It is advantageous that the mounting ring has bearings for pivotally mounting the cams.

In diese Lager greifen beispielsweise Zapfen der Nocken ein, so daß die Nocken verschwenkt werden können.In this camp, for example, pins of the cam engage, so that the cams can be pivoted.

Bei einer Ausgestaltung der Erfindung ist vorgesehen, daß die Betätigungsmittel zum Betätigen des Abgabeventils als ein sich erweiterndes Ende des Austrittskanals ausgebildet sind, das ein hervorstehendes Endstück des Abgabeventils umschließt.In one embodiment of the invention it is provided that the actuating means for actuating the dispensing valve are formed as a flared end of the outlet channel, which encloses a protruding end portion of the dispensing valve.

Auf diese Weise kann der Austrittskanal mit einem Abgabeventil verbunden werden, das ein hervorstehendes ("männliches") Endstück aufweist.In this way, the exit channel can be connected to a dispensing valve having a protruding ("male") tail.

Eine alternative Ausgestaltung besteht darin, daß die Betätigungsmittel zum Betätigen des Abgabeventils als ein zylindrisches Endstück des Austrittskanals ausgebildet sind, das in ein zurücktretendes Endstück des Abgabeventils eingreift.An alternative embodiment is that the actuating means for actuating the dispensing valve are formed as a cylindrical end portion of the outlet channel, which engages in a receding end portion of the dispensing valve.

Diese Ausgestaltung ermöglicht den Anschluß des Austrittskanals an ein zurücktretendes ("weibliches") Endstück.This embodiment allows the connection of the outlet channel to a receding ("female") tail.

Ebenfalls liegt es im Rahmen der Erfindung, daß eine abnehmbare Schutzkappe vorgesehen ist, die auf den Druckbehälter, den Befestigungsring oder den Kappenkörper aufsteckbar ist, um die Ausgangsöffnung des Austrittskanals und den Betätigungsknopf bzw. die Betätigungsknöpfe abzudecken.It is also within the scope of the invention that a removable protective cap is provided which can be plugged onto the pressure vessel, the fastening ring or the cap body to cover the outlet opening of the outlet channel and the actuating button or buttons.

Diese Schutzkappe stellt sicher, daß es zu keiner unbeabsichtigten Betätigung des Abgabeventils kommt, beispielsweise während des Transportes des Druckbehälters.This protective cap ensures that there is no unintentional actuation of the dispensing valve, for example during the transport of the pressure vessel.

Schließlich ist zur Erfindung gehörig, daß die Schutzkappe einen Pfropfen zur Abdeckung des Austrittskanals aufweist.Finally, it is part of the invention that the protective cap has a plug for covering the outlet channel.

Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand von Zeichnungen näher erläutert.An embodiment of the invention will be explained in more detail with reference to drawings.

Wie aus den Fig. 1a und 1b ersichtlich, wird die Sprühkappe 1 mit einem Druckbehälter 2, der ein unter Druck stehendes Fluid enthält, verbunden. Der Druckbehälter 2 weist ein Abgabeventil 3 auf, das, wenn es eingedrückt wird, das Fluid abgibt.Like from the Fig. 1a and 1b As can be seen, the spray cap 1 is connected to a pressure vessel 2 containing a pressurized fluid. The pressure vessel 2 has a dispensing valve 3, which, when it is pressed, discharges the fluid.

Die Sprühkappe 1 weist einen Kappenkörper 4 auf, in dessen Inneren ein Austrittskanal 5 angeordnet ist, der im vorliegenden Fall in der Längsachse des Druckbehälters 2 angeordnet ist. Das untere Ende des Austrittskanals 5 ist mit Betätigungsmitteln 6 zum Betätigen des Abgabeventils 3 versehen und das freie obere Ende ragt im unbetätigten Zustand der Sprühkappe 1 leicht über die Oberseite des Kappenkörpers 4 hinaus und schließt im betätigten Zustand in etwa mit dieser ab.The spray cap 1 has a cap body 4, in whose interior an outlet channel 5 is arranged, which is arranged in the present case in the longitudinal axis of the pressure vessel 2. The lower end of the outlet channel 5 is provided with actuating means 6 for actuating the dispensing valve 3 and the free upper end projects in the unactuated state of the spray cap 1 slightly beyond the top of the cap body 4 and closes in the actuated state about this.

Weiterhin sind Mittel zum Bewegen des Austrittskanals 5 in Richtung auf das Abgabeventil 3 vorgesehen, die dazu dienen, das Abgabeventil 3 zu betätigen. Diese Mittel zum Bewegen des Austrittskanals 5 sind als um eine senkrecht zur Achse des Abgabeventils 3 schwenkbare Nocken 7 und im wesentlichen radial an der Außenwand des Austrittskanals angeordnete Druckflächen 8 ausgebildet, auf die die Nocken 7 Druck ausüben, wenn sie zum Inneren des Kappenkörpers 4 hin verschwenkt werden.Furthermore, means for moving the outlet channel 5 are provided in the direction of the dispensing valve 3, which serve to actuate the dispensing valve 3. These means for moving the outlet channel 5 are designed as around a perpendicular to the axis of the dispensing valve 3 pivotable cam 7 and arranged substantially radially on the outer wall of the outlet channel pressure surfaces 8 on which the cam 7 exert pressure when they are to the interior of the cap body 4 out be pivoted.

Dieses Verschwenken der Nocken 7 wird über Betätigungsknöpfe 9 an der Seitenfläche des Kappenkörpers 4 eingeleitet, die Druck auf die Nocken 7 ausüben. Im vorliegenden Beispiel auch beide zusammen betätigt werden können, um über die Nocken 7 Druck auf die Druckflächen 8 auszuüben, wodurch der Austrittskanal 5 nach unten bewegt wird und das Ausgabeventil betätigt.This pivoting of the cam 7 is initiated via operating buttons 9 on the side surface of the cap body 4, the pressure on the cam 7 exert. In the present example also both can be actuated together to exert pressure on the pressure surfaces 8 via the cams 7, whereby the outlet channel 5 is moved downwards and actuates the dispensing valve.

Wie in Fig. 2 dargestellt, weist jede Nocke 7 zwei im wesentlichen parallel zueinander angeordnete Platten 10 auf, die diesseits und jenseits des Austrittskanals 5 angeordnet werden, wobei die beiden Platten 10 im gezeigten Ausführungsbeispiel über ein Verbindungsteil 11 miteinander verbunden sind, was jedoch nicht der Fall sein muß. Die Platten 10 sind keilförmig ausgestaltet. Weiterhin sind Zapfen 12 zum Eingriff in ein Lager vorgesehen.As in Fig. 2 illustrated, each cam 7 has two substantially mutually parallel plates 10, which are arranged on either side of and beyond the outlet channel 5, wherein the two plates 10 are connected in the embodiment shown by a connecting part 11 with each other, but this need not be the case. The plates 10 are wedge-shaped. Furthermore, pins 12 are provided for engagement in a bearing.

Der Betätigungsknopf 9 kann wie im gezeigten Ausführungsbeispiel mit den Nocken 7 verbunden sein, es ist aber auch möglich, daß der Betätigungsknopf 9 und die Nocke 7 getrennte Bauteile sind.The operating knob 9 may be connected as in the embodiment shown with the cam 7, but it is also possible that the operating knob 9 and the cam 7 are separate components.

Die Fig. 3a, 3b und 3c zeigen, daß auf dem Druckbehälter 2 ein Befestigungsring 13 angeordnet ist, beispielsweise auf diesem eingerastet ist, an dem der Austrittskanal 5 über Federelemente 14, die als zickzackförmige Bänder ausgebildet und mit den Druckflächen 8 des Austrittkanals 5 verbunden sind, befestigt ist. Weiterhin weist der Befestigungsring 13 Lager 15 zur schwenkbaren Lagerung der Nocken 7 auf. In diese Lager 15 greifen die Zapfen 12 der Nocken 7 ein. Es ist bei der gezeigten Ausführungsform deutlich zu erkennen, daß die Druckfläche 8 den Austrittskanal 5 plattformartig umgibt, wobei der senkrecht zu der Drehachse der Nocken 7 angeordnete Bereich, auf den die Nocken 7 Druck ausüben, zum Druckbehälter 2 hin, also nach unten gewölbt ausgebildet ist, um das Abrollen der Nocken 7 zu erleichtern und die Druckfläche 8 rigider auszugestalten.The Fig. 3a . 3b and 3c show that on the pressure vessel 2, a fastening ring 13 is arranged, for example, is engaged on this, at which the outlet channel 5 via spring elements 14, which are formed as a zigzag-shaped bands and connected to the pressure surfaces 8 of the outlet channel 5, is attached. Furthermore, the mounting ring 13 bearing 15 for pivotally mounting the cam 7. In this bearing 15, the pins 12 engage the cam 7 a. It can be seen clearly in the embodiment shown that the pressure surface 8 surrounds the outlet channel 5 in a platform-like manner, wherein the region perpendicular to the axis of rotation of the cams 7, on which the cams 7 exert pressure, is designed to be curved downwards towards the pressure vessel 2 is to facilitate the rolling of the cam 7 and to design the pressure surface 8 more rigid.

Die Fig. 4a und 4b, 5a und 5b sowie 6a und 6b zeigen darüber hinaus die Nocken 7 und die Betätigungsknöpfe 9, über die das Abgabeventil 3 betätigt wird. Es ist deutlich zu erkennen, daß diese Betätigungsknöpfe 9 in einer zum Austrittskanal 5 im wesentlichen senkrechten Richtung betätigt werden. Weiterhin ist ersichtlich, wie die Nocken 7 auf der plattformartig ausgebildeten Druckfläche 8 abrollen, wenn einer der Betätigungsknöpfe 9 oder beide Betätigungsknöpfe 9 betätigt werden und wie durch diese Druckausübung der Austrittskanal 5 zum Druckbehälter 2 hin nach unten bewegt wird, um das Abgabeventil 3 zu öffnen.The Fig. 4a and 4b . 5a and 5b 6a and 6b also show the cams 7 and the operating buttons 9, via which the dispensing valve 3 is actuated. It can be clearly seen that these actuation buttons 9 are actuated in a direction substantially perpendicular to the outlet channel 5. Furthermore, it can be seen how the cams 7 roll on the platform-like pressure surface 8 when one of the operation buttons 9 or both actuation buttons 9 are actuated and as moved by this pressure exercise the outlet channel 5 to the pressure vessel 2 down to open the dispensing valve 3 ,

Aus den Draufsichten der Fig. 7a und 7b ist zu erkennen, daß der Austrittskanal 5 im gezeigten Ausführungsbeispiel zentral in Richtung der Längsachse der Sprühkappe 1 angeordnet ist und die Betätigungsknöpfe 9 sich an den Seitenflächen des Kappenkörpers 4 befinden. Es ist jedoch auch möglich, daß der Austrittskanal 5 abgewinkelt ausgestaltet ist, so daß das Fluid senkrecht zur Längsachse der Sprühkappe 1 austritt, also statt in vertikaler in horizontaler Richtung.From the top views of Fig. 7a and 7b It can be seen that the outlet channel 5 is arranged centrally in the illustrated embodiment in the direction of the longitudinal axis of the spray cap 1 and the operation buttons 9 are located on the side surfaces of the cap body 4. However, it is also possible that the outlet channel 5 is designed angled so that the fluid emerges perpendicular to the longitudinal axis of the spray cap 1, that is, instead of in the vertical direction in the horizontal direction.

Die Fig. 8a und 8b zeigen den Kappenkörper 4, der Aussparungen für die Betätigungsknöpfe 8 aufweist. Diese Aussparungen können mit einem elastischen Material überzogen sein, welches im montierten Zustand die Betätigungsknöpfe 9 überdeckt und schützt.The Fig. 8a and 8b show the cap body 4, which has recesses for the operation buttons 8. These recesses may be coated with an elastic material, which covers the operating buttons 9 in the assembled state and protects.

Die Fig. 9a bis 9f zeigen eine Sprühkappe 1 mit einer abnehmbaren Schutzkappe 16, die dazu dient, den Austrittskanal 5 und die Betätigungsknöpfe 9 abzudecken. Wie aus diesen Figuren hervorgeht, kann sowohl der Austrittskanal 5 entsprechend dem abzugebenden Fluid unterschiedlich geformt sein und es können verschiedene Einsätze 17 im Austrittskanal 5 angeordnet sein, um das austretende Fluid zu konditionieren. Die Schutzkappe 16 kann einen Pfropfen 18 (Fig. 9f) zum Verschließen des Austrittskanals 5 aufweisen. Es ist weiterhin diesen Figuren zu entnehmen, daß die Betätigungsmittel 6 zum Betätigen des Abgabeventils 3 als ein sich erweiterndes Ende 20 des Austrittskanals 5 ausgebildet sein können, das ein hervorstehendes Endstück 21 eines Abgabeventils 3 umschließt (Fig. 9b, 9c, 9e, 9f) oder aber als ein zylindrisches Endstück 22 des Austrittskanals 5 ausgebildet sein können, das in ein zurücktretendes Endstück eines Abgabeventils 3 eingreift (Fig. 9a und 9d).The Fig. 9a to 9f show a spray cap 1 with a removable cap 16, which serves to cover the outlet channel 5 and the operating buttons 9. As can be seen from these figures, both the outlet channel 5 can be shaped differently according to the fluid to be dispensed and various inserts 17 can be arranged in the outlet channel 5 in order to condition the exiting fluid. The protective cap 16 may be a plug 18 ( Fig. 9f ) for closing the outlet channel 5. It can also be seen from these figures that the actuating means 6 for actuating the dispensing valve 3 may be formed as an expanding end 20 of the outlet channel 5, which encloses a protruding end 21 of a dispensing valve 3 ( Fig. 9b, 9c, 9e, 9f ) or may be formed as a cylindrical end piece 22 of the outlet channel 5, which engages in a receding end piece of a dispensing valve 3 ( Fig. 9a and 9d ).
