Abstract

In a spray head for a spray container for dispensing foam, the spray container having a manually actuable delivery valve in an outlet channel (6) of the spray head, and the spray head having a closure element (3a) which closes the outlet channel (6) automatically downstream of the delivery valve, the opening and closing of the closure element (3a) is delayed in each case relative to the opening and closing of the delivery valve, and the closure element (3a) allows gases, but not liquids, to escape in its closed position. In this way, the closure element not only has a shut-off function relative to a residual product contained in the outlet channel, but it also acts simultaneously as a foam outlet brake which solidifies the foam. <IMAGE>

Description

Die Erfindung bezieht sich auf einen Sprühkopf für einen Sprühbehälter zur Ausgabe von Schaum, wobei der Sprühbehälter ein manuell betätigbares Ausgabeventil in einem Austrittskanal des Sprühkopfes und der Sprühkopf ein den Austrittskanal selbsttätig und gegenüber dem Ausgabeventil verzögert schließendes Verschlußelement stromunterhalb des Ausgabeventils aufweist und das Verschlußelement etwa pilzartig geformt ist, mit seinem Stiel axial in den Austrittskanal eingeführt ist und in der Schließstellung mit dem Rand seines Pilzkopfes am Rand der Austrittsöffnung des Austrittskanals und mit einem radialen Vorsprung des Stiels an einer Hinterschneidung im Austrittskanal, diese untergreifend, anliegt.The invention relates to a spray head for a spray container for dispensing foam, the spray container having a manually operable dispensing valve in an outlet channel of the spray head and the spray head having a closure element which closes the outlet channel automatically and with a delay relative to the dispensing valve, downstream of the dispensing valve, and the closure element is somewhat mushroom-like is formed, with its stem axially inserted into the outlet channel and in the closed position with the edge of its mushroom head on the edge of the outlet opening of the outlet channel and with a radial projection of the stem against an undercut in the outlet channel, engaging under it.

Bei einem bekannten Sprühkopf dieser Art (US-A 44 37 592) wird das Verschlußelement vor dem Ausgabeventil geöffnet und nach diesem hermetisch geschlossen. Bei der Ausgabe von Schaum aus einem Aerosol- bzw. Sprühbehälter (Sprühdose) ist man jedoch daran interessiert, daß das zunächst flüssig in dem Sprühbehälter enthaltene Aerosolprodukt beim Öffnen des Ausgabeventils nicht ungebremst aus dem Sprühkopf austritt, sondern zunächst vollständig aufschäumt. Wenn das Verschlußelement jedoch vor dem Ausgabeventil öffnet, kann die Aerosolflüssigkeit zumindest teilweise austreten, bevor sie vollständig aufgeschäumt ist. Ferner ist man auch daran interessiert, den Schaum nicht ungebremst austreten zu lassen, weil sich gezeigt hat, daß ein gebremst austretender Schaum eine höhere Schaumfestigkeit erhält. Wenn andererseits das Verschlußelement hermetisch schließt, kann der zwischen dem Ausgabeventil und der Auslaßöffnung verbleibende Produktrest in dem geschlossenen Austrittskanal nachschäumen und gegebenenfalls das Verschlußelement unter dem Druck des Schaums wieder öffnen, so daß weiterhin Schaum ausströmt.In a known spray head of this type (US-A 44 37 592), the closure element is opened in front of the dispensing valve and hermetically closed after it. When dispensing foam from an aerosol or spray container (spray can), however, one is interested in the fact that the aerosol product initially contained in liquid form in the spray container does not come out of the spray head unchecked when the dispensing valve is opened, but initially foams up completely. However, if the closure element opens in front of the dispensing valve, the aerosol liquid can at least partially emerge before it is fully foamed. Furthermore, one is also interested in not allowing the foam to emerge unchecked, because it has been shown that a foam that emerges when braked has a higher foam strength. If, on the other hand, the closure element hermetically closes, the product residue remaining between the dispensing valve and the outlet opening can re-foam in the closed outlet channel and, if appropriate, open the closure element again under the pressure of the foam, so that foam continues to flow out.

Der Erfindung liegt die Aufgabe zugrunde, einen Sprühkopf der gattungsgemäßen Art anzugeben, bei dem der austretende Schaum eine höhere Festigkeit aufweist und ein Ausströmen von Schaum nach dem Schließen des Verschlußelements vermieden ist.The invention has for its object to provide a spray head of the generic type, in which the emerging foam has a higher strength and an outflow of foam is avoided after closing the closure element.

Erfindungsgemäß ist diese Aufgabe dadurch gelöst, daß das Öffnen des Verschlußelements gegenüber dem Öffnen des Ausgabeventils verzögert ist und das Verschlußelement in seiner Schließlage Gase, aber keine Flüssigkeiten austreten läßt, und daß zumindest der Pilzkopf aus elastisch biegsamem Material besteht.According to the invention, this object is achieved in that the opening of the closure element is delayed compared to the opening of the dispensing valve and the closure element allows gases but no liquids to escape in its closed position, and that at least the mushroom head consists of an elastically flexible material.

Bei dieser Lösung wirkt das verzögert öffnende Verschlußelement zunächst wie eine Schaumaustrittsbremse, so daß die Schaumfestigkeit erhöht wird. Durch das nichthermetische Schließen und den weiterhin möglichen Gasaustritt wird gleichzeitig auch ein Nachschäumen und Ausströmen von Schaum vermieden. Der Rand des Pilzkopfes biegt sich unter dem Druck des Schaums gegenüber dem Öffnen des Ausgabeventils verzögert vom Rand der Austrittsöffnung des Austrittskanals weg, um den Austritt des Schaums freizugeben. Nach dem Schließen des Ausgabeventils bewegt sich der Rand des Pilzkopfes aufgrund seiner Eigenelastizität wieder verzögert mit nachlassendem Druck des Schaums in die Schließstellung zurück.With this solution, the delayed-opening closure element initially acts like a foam outlet brake, so that the foam strength is increased. Due to the non-hermetic closing and the still possible gas outlet, after-foaming and outflow of foam is avoided at the same time. Under the pressure of the foam, the edge of the mushroom head bends away from the edge of the outlet opening of the outlet channel with a delay in relation to the opening of the dispensing valve in order to expose the outlet of the foam. After the dispensing valve is closed, the edge of the mushroom head moves with a delay due to its inherent elasticity decreasing pressure of the foam back to the closed position.

Der Austrittskanal kann in einen ersten Abschnitt und einen mit diesem zusammensteckbaren, das Verschlußelement aufweisenden zweiten Abschnitt unterteilt sein. Hierbei kann der erste Abschnitt den herkömmlichen Austrittskanal bilden, in den der zweite Abschnitt in der gewünschten Ausgestaltung einfach eingesteckt werden kann.The outlet channel can be divided into a first section and a second section which can be plugged together and has the closure element. Here, the first section can form the conventional outlet channel into which the second section can simply be inserted in the desired configuration.

Der Sprühkopf nach den Fig. 1 und 2 besteht aus einem Betätigungsaufsatz 1 für ein (nicht dargestelltes) Ausgabeventil eines Sprühbehälters zur Ausgabe von Schaum mit einem im Querschnitt etwa pilzkopfförmigen Verschlußaufsatz 2, in den ein Verschlußelement 3 in Form eines Pilzkopfes im Schnappsitz eingesetzt ist, und einer Schutzhaube 4.1 and 2 consists of an actuating attachment 1 for a (not shown) dispensing valve of a spray container for dispensing foam with an approximately mushroom-shaped closure attachment 2, in which a closure element 3 in the form of a mushroom head is inserted in a snap fit, and a protective hood 4.

Der Betätigungsaufsatz 1 hat ein vertikales Austrittsrohr 5, das einen ersten Abschnitt eines Austrittskanals 6 bildet und in das ein Rohrstutzen 7 des Verschlußaufsatzes 2 eingesetzt ist, wobei der Rohrstutzen 7 einen zweiten Abschnitt des Austrittskanals 6 bildet. Hierbei sind das Austrittsrohr 5 und der Rohrstutzen 7 im Reibschluß dicht zusammengehalten. Der axial untere Abschnitt des Austrittsrohres 5 bildet eine Fassung 8 zur Aufnahme des Austrittsendes eines Ausgaberohres des Ausgabeventils. Der Austrittskanal 6 ist teilweise durch eine sich quer in diesem erstreckende Prallwand 9 versperrt, an der die wässrige, aus dem Sprühbehälter freigegebene Aerosolflüssigkeit zunächst aufschäumen kann.The actuating attachment 1 has a vertical outlet pipe 5, which forms a first section of an outlet channel 6 and into which a pipe socket 7 of the closure cap 2 is inserted, the pipe socket 7 forming a second section of the outlet channel 6. Here, the outlet pipe 5 and the pipe socket 7 are held tightly together in the frictional engagement. The axially lower section of the outlet tube 5 forms a socket 8 for receiving the outlet end of an outlet tube of the outlet valve. The outlet channel 6 is partially blocked by a baffle 9 extending transversely therein, on which the aqueous aerosol liquid released from the spray container can initially foam.

Die obere Wand 10 des Betätigungsaufsatzes 1 ist nur auf der einen (in Fig. 1 linken) Seite des Austrittsrohres 5 mit dem oberen Rand einer radial äußeren, auf den oberen Rand des Sprühbehälters im Schnappsitz aufsetzbaren Umfangswand 11 des Betätigungsaufsatzes 1 einteilig verbunden. Die Wand 10 besteht aus biegsamem Material. Daher kann durch Niederdrücken einer der Verbindungsstelle zwischen den Wänden 10 und 11 diametral gegenüberliegenden Betätigungsstufe 12 ein Druck auf das in die Fassung 8 eingreifende Ausgaberohr des Ausgabeventils ausgeübt werden. Durch das Niederdrücken des Ausgaberohrs, das zugleich einen Verschlußteil des Ausgabeventils bildet, wird das Ausgabeventil geöffnet.The upper wall 10 of the actuating attachment 1 is connected in one piece only on one side (in FIG. 1) of the outlet pipe 5 to the upper edge of a radially outer peripheral wall 11 of the actuating attachment 1 which can be snapped onto the upper edge of the spray container. The wall 10 is made of flexible material. Therefore, by depressing one of the connection points between the walls 10 and 11 diametrically opposite actuating step 12, pressure can be exerted on the dispensing tube of the dispensing valve which engages in the socket 8. The dispensing valve is opened by depressing the dispensing tube, which at the same time forms a closure part of the dispensing valve.

Das Verschlußelement 3 ist etwa pilzartig geformt und mit seinem Stiel 13 axial in den Austrittskanal 6 eingeführt. Der Stiel 13 hat einen radialen Vorsprung 14 in Form eines umlaufenden Wulstes, der eine Hinterschneidung 15 untergreift, die ebenfalls durch einen radial nach innen vorstehenden Wulst im Austrittskanal 6 gebildet wird. In der in Fig. 1 dargestellten Schließstellung des Verschlußelements 3 liegt dieses mit dem Rand 16 seines Pilzkopfes 17 am Rand 18 der Austrittsöffnung des Austrittskanals 6 an. Der radiale Vorsprung 14 hat in der Schließstellung einen axialen Abstand d von der Hinterschneidung 15, durch den der Hub des aus starrem Material bestehenden Verschlußelements 3 bestimmt und begrenzt wird. Axiale Durchgangskanäle 19 durchsetzen den radialen Vorsprung 14 bis auf die obere Seite des die Hinterschneidung 15 bildenden Vorsprungs. Der Pilzkopf 17 des Verschlußelements 3 ist in einer axialen Vertiefung 20 in der pilzkopfartigen Erweiterung des Verschlußaufsatzes 2 weitgehend bündig versenkt.The closure element 3 is shaped like a mushroom and axially inserted into the outlet channel 6 with its stem 13. The stem 13 has a radial projection 14 in the form of a circumferential bead, which engages under an undercut 15, which is also formed by a bead protruding radially inwards in the outlet channel 6. In the closed position of the closure element 3 shown in FIG. 1, this lies with the edge 16 of its mushroom head 17 on the edge 18 of the outlet opening of the outlet channel 6. In the closed position, the radial projection 14 has an axial distance d from the undercut 15, through which the stroke of the closure element 3, which is made of rigid material, is determined and limited. Axial through channels 19 penetrate the radial projection 14 up to the upper side of the projection forming the undercut 15. The mushroom head 17 of the closure element 3 is sunk largely flush in an axial recess 20 in the mushroom-like extension of the closure attachment 2.

Wenn die Betätigungsstufe 12 niedergedrückt und das Ausgabeventil geöffnet wird, strömt der Behälterinhalt unter dem Druck eines Treibmittels über das Ausgabeventil und dessen Ausgaberohr gegen die Prallwand 9, von der es unter Aufschäumung in das Austrittsrohr 5 und den Rohrstutzen 7 umgeleitet wird. Hier trifft es auf das die Schließstellung nach Fig. 1 einnehmende Verschlußelement 3, wobei dieses gegen seine Schwerkraft (bzw. sein Gewicht) unter dem Druck des Schaums verzögert in die Öffnungsstellung nach Fig. 2 angehoben wird und wie eine Schaumaustrittsbremse wirkt. Durch diesen "gebremsten" Austritt des Schaums wird dessen Festigkeit erhöht.When the actuation stage 12 is depressed and the dispensing valve is opened, the contents of the container flow under the pressure of a propellant via the dispensing valve and its dispensing tube against the baffle wall 9, from which it is redirected with foaming into the outlet pipe 5 and the pipe socket 7. Here it meets the closure element 3 which takes up the closed position according to FIG. 1, whereby this is raised against its gravity (or its weight) under the pressure of the foam with a delay into the open position according to FIG. 2 and acts like a foam outlet brake. This "braked" exit of the foam increases its strength.

Sobald der Druck von der Betätigungstaste 12 weggenommen wird, schließt sich das Ausgabeventil, während das Verschlußelement 3 weiterhin unter dem Druck des Schaums die Öffnungsstellung beibehält.As soon as the pressure is released from the actuation button 12, the dispensing valve closes, while the closure element 3 continues to maintain the open position under the pressure of the foam.

In aufrechter Lage des Sprühbehälters und dementsprechend vertikaler Lage des Ausgangskanals 6 sinkt nun das Verschlußelement 3 bei nachlassendem Schaumdruck in die Schließstellung zurück. Alternativ kann das Verschlußelement 3 auch manuell beim Abstreifen des ausgetretenen Schaums in die Schließstellung zurückgedrückt werden. In der Schließstellung kann durch den nicht hermetisch dichten Schließspalt zwischen Verschlußelement 3 und Verschlußaufsatz 2 weiterhin Gas austreten, während der Schaum bzw. sich in dem Austrittskanal 6 bildende Flüssigkeit zurückgehalten wird und gleichzeitig verhindert wird, daß der im Austrittskanal verbleibende Produktrest sich unter Luftzutritt verändern kann.In the upright position of the spray container and accordingly the vertical position of the outlet channel 6, the closure element 3 now sinks back into the closed position when the foam pressure decreases. Alternatively, the closure element 3 can also be manually stripped of the leaked Foam are pushed back into the closed position. In the closed position, gas can continue to escape through the non-hermetically sealed closing gap between the closure element 3 and the closure attachment 2, while the foam or liquid forming in the outlet channel 6 is retained and at the same time it is prevented that the product residue remaining in the outlet channel can change under air access .

Die Fig. 3 und 4 zeigen einen abgewandelten Verschlußaufsatz 2a, der zusammen mit dem Betätigungsaufsatz 1 verwendet werden kann und bei dem das ebenfalls pilzkopfförmige Verschlußelement 3a nicht starr, sondern aus elastisch biegsamem Material hergestellt ist. Die Durchgangskanäle 19a sind nicht im Stiel 13a, sondern in einem sich konisch aufweitenden Teil des Rohrstutzens 7a ausgebildet. Dementsprechend ist der radiale Vorsprung 14a des Stiels 13a in Umfangsrichtung durchgehend ausgebildet und die Hinterschneidung 15a in Umfangsrichtung durch die Durchgangskanäle 19a unterbrochen. Der Vorsprung 14a hat keinen axialen Abstand von der Hinterschneidung 15a, sondern liegt ständig an dieser an.3 and 4 show a modified closure attachment 2a, which can be used together with the actuating attachment 1 and in which the mushroom-shaped closure element 3a is not rigid, but is made of an elastically flexible material. The through-channels 19a are not formed in the stem 13a, but in a conically widening part of the pipe socket 7a. Accordingly, the radial projection 14a of the stem 13a is continuous in the circumferential direction and the undercut 15a is interrupted in the circumferential direction by the through channels 19a. The projection 14a has no axial distance from the undercut 15a, but is constantly in contact with it.

Beim Öffnen des Ausgabeventils wird das Verschlußelement 3a mithin nicht angehoben, sondern lediglich sein Rand 16 durch den Druck des Schaums axial nach oben gebogen und auf diese Weise das Verschlußelement 3a verzögert in die (nicht dargestellte) Öffnungsstellung gebracht. Nach dem Schließen des Ausgabeventils wird der Öffnungsrand 16 wieder bis zur Anlage an den Rand 18 aufgrund seiner Rückstellfederkraft zurückgebogen und in die Schließstellung gebracht. Das Öffnen und Schließen des Verschlußelements 3a ist daher ebenfalls jeweils gegenüber dem Öffnen und Schließen des Ausgabeventils verzögert.When the dispensing valve is opened, the closure element 3a is therefore not raised, but rather only its edge 16 is bent axially upward by the pressure of the foam, and in this way the closure element 3a is brought into the open position (not shown) with a delay. After the dispensing valve is closed, the opening edge 16 is bent back again until it rests against the edge 18 due to its return spring force and brought into the closed position. The opening and closing of the closure element 3a is therefore also delayed compared to the opening and closing of the dispensing valve.

Beim dem Sprühkopf nach Fig. 5 ist die Oberseite des Betätigungsaufsatzs 1a als etwa topfförmiger Vorsprung 21 ausgebildet, an dessen Boden 22 das Austrittsrohr 5 angeformt ist. Der Austrittskanal 6 verjüngt sich im Bereich des Bodens 22 und ist auf der Oberseite von einer axial vorstehenden Dichtkante 23 umgeben. Oben auf dem Vorsprung 21 ist das Verschlußelement 3b in Form einer Haube aus elastisch nachgiebigem gummiartigem Material im Schnappsitz aufgesetzt, wobei ein radial nach innen vorstehender Ringwulst des Verschlußelements 3b in eine radial äußere Umfangsnut des Vorsprungs 21 eingreift und der Boden der Haube eine Membran bildet, die unter Federvorspannung auf der den Rand der Austrittsöffnung des Austrittskanals 6 bildenden Dichtkante 23 anliegt. Der Boden bzw. die Membran der das Verschlußelement 3b bildenden Haube ist radial außerhalb der Dichtkante 23 mit Durchgangslöchern 24 versehen, die in der dargestellten Schließlage des Verschlußelements 3b durch die Anlage der Membran an der Dichtkante 23 gegen den Austritt von Schaum oder Flüssigkeit, nicht jedoch gegen den Durchtritt von Gas, dessen Druck höher als die Schließkraft der Membran ist, abgesperrt ist.5, the top of the actuating attachment 1a is formed as an approximately cup-shaped projection 21, on the bottom 22 of which the outlet pipe 5 is formed. The outlet channel 6 tapers in the region of the base 22 and is surrounded on the upper side by an axially projecting sealing edge 23. The closure element 3b in the form of a hood made of elastically resilient rubber-like material is snap-fitted onto the top of the projection 21, a radially inwardly projecting annular bead of the closure element 3b engaging in a radially outer circumferential groove of the projection 21 and the bottom of the hood forming a membrane, which rests under spring tension on the sealing edge 23 forming the edge of the outlet opening of the outlet channel 6. The bottom or the membrane of the hood forming the closure element 3b is provided radially outside of the sealing edge 23 with through holes 24 which, in the illustrated closed position of the closure element 3b, do not, however, by the membrane resting against the sealing edge 23 against the escape of foam or liquid against the passage of gas, the pressure of which is higher than the closing force of the membrane.

Beim Niederdrücken der Betätigungsstufe 12 wird mithin auch bei diesem Ausführungsbeispiel zunächst das (nicht dargestellte) Ausgabeventil geöffnet und sodann nach Ausbildung von Schaum unter hinreichendem Druck im Ausgangskanal 6 des Austrittsrohrs 5 die Membran von der Dichtkante 23 abgehoben, so daß der Schaum über die Durchgangslöcher 24 austreten kann. Umgekehrt kehrt die Membran nach Wegnahme des Drucks von der Betätigungsstufe 12 und Schließen des Ausgabeventils erst dann wieder in die dargestellte Schließlage zurück, nachdem sich der Druck im Ausgangskanal 6 abgebaut hat.When the actuation stage 12 is depressed, the dispensing valve (not shown) is therefore also opened in this exemplary embodiment and then, after the formation of foam under sufficient pressure in the outlet channel 6 of the outlet pipe 5, the membrane is lifted off the sealing edge 23, so that the foam passes through the through holes 24 can leak. Conversely, after the pressure has been removed from the actuation stage 12 and the dispensing valve has closed, the membrane only returns to the illustrated closed position after the pressure in the outlet channel 6 has decreased.

Auch hier hat die gelochte Membran die Funktion einer Schaumbremse. Dagegen ist eine Prallwand nicht vorgesehen.Here, too, the perforated membrane has the function of a foam brake. In contrast, a baffle is not provided.

Anstelle in der Draufsicht kreisförmiger Verschlußelemente, wie dargestellt, können auch mehreckige, z.B. viereckige, Verschlußelemente und entsprechend in der Form angepaßte Betätigungsaufsätze bei im übrigen gleicher Ausbildung, wie dargestellt, vorgesehen sein.Instead of circular closure elements in the plan view, as shown, polygonal, e.g. quadrangular, closure elements and correspondingly adapted actuating attachments with the same design, as shown, can be provided.
