Aus US 3,904,088 ist eine Sprühkappe gemäß des Oberbegriffs des Anspruchs 1 bekannt, die eine seitlich angelenkte Verschlußklappe besitzt. Die Verschlußklappe trägt einen Vorsprung auf der Innenseite, der im verschlossenen Zustand der Verschlußklappe unter einer Austrittsdüse in ein Aufsatzelement eingreift. Eine Betätigung der Sprühkappe ist auf dieser Weise gesperrt.From US 3,904,088 a spray cap according to the preamble of claim 1 is known, which has a laterally hinged flap. The flap carries a projection on the inside, which engages in the closed state of the flap under an outlet nozzle in an attachment element. Actuation of the spray cap is locked in this way.

Aus WO 02/43872 A2 ist eine Sprühkappe für ein Aerosolbehälter bekannt, die einen zylindrischen Aufsatz mit einem darin gelagerten Betätigungselement besitzt. An dem Aufsatzelement angelenkt ist eine Verschlußklappe, die einen Vorsprung und einen Dichtungsring besitzt. Das Betätigungselement besitzt eine zur Verschlußklappe weisende Austrittsöffnung und eine Durchbrechung für den Verriegelungsvorsprung. In der geschlossenen Position ist der Vorsprung der Verschlußklappe in der Öffnung des Betätigungselements und der Dichtring innerhalb der Austrittsöffnung angeordnet.WO 02/43872 A2 discloses a spray cap for an aerosol container which has a cylindrical attachment with an actuating element mounted therein. Fastened to the attachment element is a closure flap which has a projection and a sealing ring. The actuating element has an outlet opening facing the closure flap and an opening for the locking projection. In the closed position, the projection of the closure flap in the opening of the actuating element and the sealing ring is arranged within the outlet opening.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Sprühkopf für Schäume oder Gele zur Verfügung zu stellen, der mit einfachen Mitteln Verunreinigungen an einer Verschlußklappe vermeidet.The present invention has for its object to provide a spray head for To provide foams or gels, which avoids contaminants on a flap by simple means.

Erfindungsgemäß wird die Aufgabe durch einen Sprühkopf mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden den Gegenstand der Unteransprüche.According to the invention the object is achieved by a spray head with the features of claim 1. Advantageous embodiments form the subject of the dependent claims.

Bei dem erfindungsgemäßen Sprühkopf zum Austragen von Schaum, Gel oder einem anderen Medium aus einem mit einem Ventil versehenen Behälter sind ein Aufsatzelement und ein Betätigungselement vorgesehen. Das Aufsatzelement sitzt auf dem Behälter, vorzugsweise tellerübergreifend. In dem Aufsatzelement ist das Betätigungselement beweglich gelagert. Das Betätigungselement besitzt eine Austrittsöffnung und einen Druckabschnitt, wobei es nicht erforderlich ist, daß der Druckabschnitt besonders ausgestaltet oder gekennzeichnet ist. Die Austrittsöffnung des Betätigungselements ist über einen Stutzen mit der Ventilöffnung verbunden. Bei einem Druck auf den Druckabschnitt des Betätigungselements wird das Ventil geöffnet und das in dem Behälter enthaltene Medium wird durch den Stutzen über die Austrittsöffnung ausgetragen. Ein an dem Aufsatzelement befestigtes Verschlußelement verschließt in seiner geschlossenen Position die Austrittsöffnung. Das Verschlußelement und das Betätigungselement besitzen eine Verriegelungseinrichtung, die in der geschlossenen Position des Verschlußelements ein Auslösen des Betätigungselements sperrt. Das Verschlußelement ist an dem Aufsatzelement angelenkt. Über die Verriegelungseinrichtung wird in der geschlossenen Position auch die Position des Betätigungselements relativ zu dem Behälter festgelegt, so daß eine versehentliche Betätigung des Ventils nicht erfolgen kann. Bei dem erfindungsgemäßen Sprühkopf kann auf eine Überkappe verzichtet werden, da eine unbeabsichtigte Betätigung bereits durch das Verschlußelement vermieden wird. Hinzu kommt, daß das Verschlußelement in seiner verriegelten Stellung auch die Aus trittsöffnung verschließt und somit die Bildung und/oder den Austritt von Schaum-oder Gelresten verhindert. Erfindungsgemäß besitzt das Aufsatzelement mindestens zwei Öffnungen, von denen in einer ersten Öffnung der Druckbereich des Betätigungselements und in der zweiten Öffnung die Austrittsöffnung des Betätigungselements frei liegt. In dieser Ausgestaltung des Sprühkopfs ist das Verschlußelement in einem Bereich zwischen erster und zweiter Öffnung an der Spitze des Aufsatzelements angelenkt. Das Verschlußelement trägt hierbei bevorzugt an seinem von der Anlenkung fortweisenden Ende den Vorsprung der Verriegelungseinrichtung, der in das Betätigungselement eingreift. Ferner ist auf der Innenseite des Verschlußelements ein kreisförmiger Dichtwulst ausgebildet.In the spray head according to the invention for discharging foam, gel or other medium from a container provided with a valve, an attachment element and an actuating element are provided. The attachment sits on the container, preferably plate-spreading. In the attachment element, the actuating element is movably mounted. The actuator has an outlet opening and a pressure section, wherein it is not necessary that the pressure section is particularly designed or marked. The outlet opening of the actuating element is connected via a connecting piece with the valve opening. Upon a pressure on the pressure section of the actuating element, the valve is opened and the medium contained in the container is discharged through the nozzle via the outlet opening. A fastener attached to the attachment element closes in its closed position, the outlet opening. The closure element and the actuating element have a locking device which blocks a triggering of the actuating element in the closed position of the closure element. The closure element is articulated on the attachment element. About the locking device, the position of the actuating element is set relative to the container in the closed position, so that an accidental operation of the valve can not be done. In the spray head according to the invention can be dispensed with an overcap, since accidental operation is already avoided by the closure element. In addition, the closure element in its locked position and the outlet opening closes and thus the formation and / or the escape of foam or Gel residue prevented. According to the invention, the attachment element has at least two openings, of which the pressure area of the actuating element is in a first opening and the outlet opening of the actuating element is exposed in the second opening. In this embodiment of the spray head, the closure element is articulated in a region between the first and second openings at the top of the attachment element. In this case, the closure element preferably carries, at its end pointing away from the articulation, the projection of the locking device, which engages in the actuating element. Furthermore, a circular sealing bead is formed on the inside of the closure element.

In einer bevorzugten Ausgestaltung besteht die Verriegelungseinrichtung aus einer Ausnehmung und einem Vorsprung, die in der geschlossenen Position des Verschlußelements ineinandergreifen. Hierdurch wird ein Auslösen des Betätigungselements gesperrt. Bevorzugt ist das Verschlußelement mit einem stiftförmigen Vorsprung versehen, der in der geschlossenen Position in eine Ausnehmung in dem korrespondierenden Betätigungselement eingreift. Der Vorsprung verriegelt das Betätigungselement derart, daß das Ventil des Behälters geschlossen ist.In a preferred embodiment, the locking device consists of a recess and a projection which engage in the closed position of the closure element. As a result, a triggering of the actuating element is blocked. Preferably, the closure element is provided with a pin-shaped projection which engages in the closed position in a recess in the corresponding actuating element. The projection locks the actuator such that the valve of the container is closed.

Um ein Nachschäumen des Sprühkopfs wirksam zu verhindern, können auf der Innenseite des Verschlußelements vorstehende Abschnitte angeordnet sein, die in der geschlossenen Position des Verschlußelements in die Austrittsöffnung vorstehen. Ist die Austrittsöffnung beispielsweise sternförmig ausgebildet, so kann auch der vorstehende Abschnitt sternförmig ausgebildet sein, um in die Austrittsöffnung vorzustehen. Der vorstehende Abschnitt kann aber auch teilweise in die Austrittsöffnung vorstehen. Befindet sich bei dem erfindungsgemäßen Sprühkopf das Verschlußelement in seiner geschlossenen Position, so ist das Betätigungselement gesperrt und die Austrittsöffnung durch den vorstehenden Abschnitt abgedichtet, so daß ein Nachschäumen unterbleibt und eine versehentliche Betätigung ausgeschlossen ist. Der vorstehende Abschnitt kann einstückig in dem Verschlußelement ausgeformt sein.In order to effectively prevent re-foaming of the spray head, protruding portions may be arranged on the inside of the closure element, which project into the outlet opening in the closed position of the closure element. For example, if the outlet opening is star-shaped, then the protruding section can also be configured star-shaped in order to protrude into the outlet opening. The projecting portion may also protrude partially into the outlet opening. If, in the spray head according to the invention, the closure element is in its closed position, the actuating element is blocked and the outlet opening is sealed by the protruding section, so that re-foaming is avoided and accidental operation is precluded. The protruding portion may be integrally formed in the closure member.

In einer alternativen Ausgestaltung ist das Verschlußelement mit einem Einsatz versehen, der den vorstehenden Abschnitt für die Austrittsöffnung trägt. Der Einsatz kann fest in das Verschlußelement eingesetzt werden.In an alternative embodiment, the closure element is provided with an insert which carries the projecting portion for the outlet opening. The insert can be firmly inserted into the closure element.

Das Verschlußelement ist bevorzugt in Form einer Klappe ausgeführt, die weniger als eine Hälfte des Sprühkopfes bedeckt.The closure element is preferably designed in the form of a flap which covers less than one half of the spray head.

Aus einer zweiten Öffnung 20 des Aufsatzes 10 steht das Betätigungselement mit seiner Öffnung 16 leicht vor. Wird das Betätigungselement 12 im Bereich 14 gedrückt, so gibt das Betätigungselement 12 die Öffnung 20 teilweise frei, insbesondere im Bereich der Spitze des Aufsatzelements (vgl. Fig. 1d). Figur 1d zeigt mit B beispielhaft einen austretenden Schaum.The attachment 10 has an opening in which the actuating element 12 is freely accessible with its pressure region 14. From a second opening 20 of the attachment 10, the actuator with its opening 16 is slightly ahead. If the actuating element 12 is pressed in the region 14, then the actuating element 12 releases the opening 20 partially, in particular in the region of the tip of the attachment element (cf., FIG. FIG. 1d shows by way of example a leaking foam.

An dem Aufsatz 10 ist eine Verschlußklappe 22 in einem Bereich 24 angelenkt. Die Verschlußklappe 22 ist in ihrer Form an den Aufsatz 10 und das Betätigungselement 12 im Bereich seiner Austrittsöffnung angepaßt, so daß der Aufsatz in der geschlossenen Position eine durchgehende Kontur besitzt. Der Bereich 24 liegt zwischen der ersten Öffnung 18 und der zweiten Öffnung 20. Die Verschlußklappe 22 besitzt an ihrem von der Anlenkung fortweisenden Ende einen stiftförmigen Verriegelungsvorsprung 26. Im inneren der Verschlußklappe ist ein Hohlzapfen 28 als vorstehender Abschnitt angeformt, der in der geschlossenen Position der Klappe 22 in die Austrittsöffnung 16 taucht und diese verschließt. In der in Fig. 1a dargestellten geschlossenen Position, ist der Vorsprung 26 in einer Bohrung 30 (vgl. Fig. 1b) in dem Betätigungselement unterhalb der Austrittsöffnung 16 angeordnet. Hierdurch wird die Position des Betätigungselements festgelegt. Unterstützt wird dies noch dadurch, daß die Verschlußklappe 22 an dem Aufsatz 10 im Bereich 31 flächig anliegt.At the top 10, a closure flap 22 is articulated in a region 24. The flap 22 is adapted in shape to the top 10 and the actuator 12 in the region of its outlet opening, so that the article has a continuous contour in the closed position. The region 24 lies between the first opening 18 and the second opening 20. The closure flap 22 has In the interior of the closure flap, a hollow pin 28 is formed as a projecting portion which dives into the closed position of the flap 22 in the outlet opening 16 and closes it. In the closed position shown in Fig. 1a, the projection 26 is arranged in a bore 30 (see Fig. 1b) in the actuating element below the outlet opening 16. As a result, the position of the actuating element is determined. This is further supported by the fact that the flap 22 rests flat against the attachment 10 in the region 31.

Figuren 2a bis 2d zeigen eine perspektivische Ansicht des Sprühkopfes aus Fig. 1, wobei gleiche Elemente mit gleichen Bezugszeichen versehen sind. In der Darstellung von Figur 2 ist zu erkennen, daß der Druckbereich 14 eine im wesentlichen ovale Form besitzt. Wie in Figur 2b und 2c deutlich zu erkennen, ist die Wandung 33 des Aufsatzes 10 im Druckbereich tiefergezogen.Figures 2a to 2d show a perspective view of the spray head of Fig. 1, wherein like elements are provided with the same reference numerals. In the illustration of Figure 2 it can be seen that the pressure region 14 has a substantially oval shape. As can clearly be seen in FIGS. 2b and 2c, the wall 33 of the attachment 10 is pulled deeper in the pressure region.

Figur 3 zeigt eine Detailansicht zur Verbindung von Betätigungselement 12 und Aufsatz 10. Die entsprechende Verbindung ist in Figur 1 mit dem Bezugszeichen 35 gekennzeichnet. Betätigungselement 12 und Aufsatz 10 sind über einen Steg 37 miteinander verbunden. Der Steg 37 mündet in die Außenfläche des Betätigungselements 12 einen t-förmigen Anschluß bildend, während der Steg 37 aus dem Ende des Aufsatzes 10 herausgeformt ist.FIG. 3 shows a detailed view of the connection of actuating element 12 and attachment 10. The corresponding connection is identified in FIG. 1 by reference numeral 35. Actuating element 12 and attachment 10 are connected to each other via a web 37. The web 37 opens into the outer surface of the actuating element 12 forming a T-shaped connection, while the web 37 is formed out of the end of the attachment 10.

Figur 4 zeigt die Detailansicht einer zusätzlichen inneren Dichtung 39, die in der Verschlußklappe 22 angeformt ist. Die zusätzliche Dichtung 39 ist als kreisförmiger Wulst ausgebildet, der in der verschlossenen Position der Klappe gegen das Betätigungselement im Bereich um die Austrittsöffnung 16 anliegt.Figure 4 shows the detailed view of an additional inner seal 39 which is integrally formed in the closure flap 22. The additional seal 39 is formed as a circular bead which rests in the closed position of the flap against the actuating element in the region around the outlet opening 16.

Figur 5 zeigt den Verriegelungsmechanismus im Detail. Der Stift 26 mit einer abgerundeten Spitze reicht durch die Öffnung 31 in dem Betätigungselement durch und steht aus der Innenseite der Verschlußklappe 22 vor. Zum besseren Halt der Verschlußklappe in der Verriegelungsposition ist in der Öffnung 31 ein umlaufender Wulst 41 ausgeformt, dessen Innendurchmesser dem Außendurchmesser des Stifts 26 entspricht.Figure 5 shows the locking mechanism in detail. The pin 26 with a rounded tip extends through the opening 31 in the actuator and protrudes from the inside of the flap 22. For better support of the closure flap in the locking position, a circumferential bead 41 is formed in the opening 31, whose inner diameter corresponds to the outer diameter of the pin 26.

Figuren 6a bis 6e zeigen eine perspektivische Ansicht des Sprühkopfs aus Figur 1 in seiner geöffneten Position. Gleiche Elemente sind wieder mit gleichen Bezugszeichen versehen. Aus Figur 6a ist deutlich zu erkennen, daß die Austrittsöffnung 16 sternförmig ausgebildet ist, wobei von einer zentralen Bohrung 16 aus Austrittsschlitze 43 radial abstehen. Ebenfalls in Figur 6a ist zu erkennen, daß um die Austrittsschlitze 43 herum ein Absatz 45 in dem Betätigungselement vorgesehen ist, der über den Wulst 39 abgedichtet wird.Figures 6a to 6e show a perspective view of the spray head of Figure 1 in its open position. The same elements are again provided with the same reference numerals. It can be seen clearly from FIG. 6a that the outlet opening 16 is of star-shaped design, with outlet slots 43 protruding radially from a central bore 16. It can also be seen in FIG. 6 a that a shoulder 45 is provided in the actuating element around the outlet slots 43 and is sealed off via the bead 39.

Figur 6a zeigt eine perspektivische Ansicht von vorne, während Figur 6b eine perspektivische Ansicht bei geöffneter Verschlußklappe 22 von der Seite zeigt. Figur 6c zeigt den Sprühkopf von hinten mit einer Draufsicht auf den Druckbereich 14. Figur 6d zeigt eine Schnittansicht, die im wesentlichen Figur 1 entspricht, wobei die Sprühkappe nicht auf einen Behälter aufgesetzt ist. Figur 6e zeigt die Sprühkappe in einer perspektivischen Ansicht von oben.FIG. 6a shows a perspective view from the front, while FIG. 6b shows a perspective view when the closure flap 22 is open from the side. Figure 6c shows the spray head from behind with a plan view of the pressure area 14. Figure 6d shows a sectional view, which substantially corresponds to Figure 1, wherein the spray cap is not placed on a container. FIG. 6e shows the spray cap in a perspective view from above.

Figur 6f ist eine Detailansicht des Verbindungsstücks 24. Aus dem Aufsatz steht im Bereich der Spitze ein Vorsprung 47 vor. Über einen Bereich mit verminderter Wandstärke geht der Vorsprung 47 in einen Vorsprung 45 über, der aus der Verschlußklappe 22 vorsteht.FIG. 6f is a detail view of the connecting piece 24. From the attachment there is a projection 47 in the region of the tip. Over an area with reduced wall thickness of the projection 47 is in a projection 45, which protrudes from the flap 22.

Figur 7 zeigt ein altematives Ausführungsbeispiel für den erfindungsgemäßen Sprühkopf. In dieser Ausgestaltung besitzt der Sprühkopf einen Aufsatz 34, aus dem das Betätigungselement 36 vorsteht. Das Betätigungselement 36 besitzt einen Druckbereich 38. Wie in Figur 7 deutlich zu erkennen, ist die Öffnung 40 leicht versetzt auf der Spitze des Betätigungselements 36 angeordnet. Auch in diesem Ausführungsbeispiel ist die Austrittsöffnung 40 wieder sternförmig ausgebildet und in einem kreisförmigen ebenem Abschnitt 42 angeordnet.FIG. 7 shows an alternative embodiment for the spray head according to the invention. In this embodiment, the spray head has a top 34 from which the actuator 36 protrudes. The actuating element 36 has a pressure region 38. As can be clearly seen in FIG. 7, the opening 40 is arranged slightly offset on the tip of the actuating element 36. Also in this embodiment, the outlet opening 40 is again star-shaped and arranged in a circular planar portion 42.

Verschlossen wird die Austrittsöffnung 40 durch eine an dem Aufsatz 34 im Bereich 44 angelenkte Klappe 46.The outlet opening 40 is closed by a flap 46 which is hinged to the attachment 34 in the area 44.

Figur 8 zeigt die Klappe 46 in ihrer geöffneten Position, während Figur 7 die geschlossene Position dargestellt. An ihrem von dem Aufsatz 34 fortweisenden Ende besitzt die Klappe 46 einen Einsatz 48 mit sternförmigen Vorsprüngen 50. In der geschlossenen Position der Klappe 46 verschließen diese die sternförmige Austrittsöffnung 40.Figure 8 shows the flap 46 in its open position, while Figure 7 shows the closed position. At its end facing away from the top 34, the flap 46 has an insert 48 with star-shaped projections 50. In the closed position of the flap 46, these close the star-shaped outlet opening 40th

An dem zum Aufsatz weisenden Ende ist die Klappe 46 mit einem Vorsprung 52 versehen. Der Vorsprung 52 greift in eine Ausnehmung 54 in dem Betätigungselement 46 ein. Hierdurch wird das Betätigungselement 36 in seiner Position relativ zu dem Aufsatz 34 und somit zu dem Behälter festgelegt, so daß kein Austrag des Mediums in der geschlossenen Position der Klappe erfolgen kann.At the end facing the attachment, the flap 46 is provided with a projection 52. The projection 52 engages in a recess 54 in the actuating element 46 a. As a result, the actuating element 36 is fixed in its position relative to the attachment 34 and thus to the container, so that no discharge of the medium can take place in the closed position of the flap.
