Description

Die Erfindung bezieht sich auf eine auslöserbetätigbare Ausgabehaube nach dem Oberbegriff des Patentanspruchs 1. Unter Innendruck stehende Behälter, wie Aerosol-Behälter, sind üblicherweise mit einem Betätigungskopf oder einer Betätigungshaube versehen, der bzw. die einen Ausgabekanal begrenzt, durch den der Inhalt des Behälters zu der im Ausgabekopf bzw. der Ausgabehaube ausgebildeten Ausgabeöffning gelangt. Um den Inhalt des Behälters auszugeben, erfaßt der Benutzer den Behälter, um dann mit einem Finger der den Behälter haltenden Hand den Kopf oder einen Teil der Haube niederzudrücken und den Inhalt des Behälters freizugeben.The invention relates to a trigger-actuated dispensing hood according to the preamble of claim 1. Containers under internal pressure, such as aerosol containers, are usually provided with an actuating head or an actuating hood which delimits an output channel through which the contents of the container are closed the dispensing opening formed in the dispensing head or dispensing hood. To dispense the contents of the container, the user grasps the container and then, with a finger of the hand holding the container, press down the head or part of the hood and release the contents of the container.

Obwohl wirtschaftlich erfolgreich, haben mittels Finger betätigbare Köpfe oder Hauben doch den Nachteil, daß sie bei einigen Benutzern zur Ermüdung des Fingers führen. Darüber hinaus ist das Treffen des gewünschten Oberflächenbereichs mit dem ausgegebenen Erzeugnis schwierig, weil das Erfassen des Behälters unter gleichzeitiger richtiger Plazierung des Fingers verhältnismäßig schwierig ist. Ein handlicheres Erfassen und Betätigen des Behälters wird mittels eines Auslösemechanismus bzw. eines Abzugs erreicht.Although economically successful, finger-operated heads or hoods have the disadvantage that they lead to finger fatigue in some users. In addition, meeting the desired surface area with the dispensed product is difficult because it is relatively difficult to grasp the container while correctly placing the finger. A more convenient grasping and actuation of the container is achieved by means of a trigger mechanism or a trigger.

Bekannte Aerosol-Behälter, die durch einen Auslösemechanismus betätigt werden, haben den Nachteil, daß die Betätigung ihres Ventils nicht optimal leicht ist, daß ein Teil des Betätigungsmechanismus über den Behälterumfang hinausragt, so daß die Gefahr einer Betätigung des Auslösers während des Transports oder der Aufbewahrung durch eine unabsichtliche Berührung besteht, und daß sie dem Verbraucher nicht besonders ästhetisch erscheinen. Bekannte durch Auslöser betätigbare Aerosol-Behälter sind in den US-Patentschriften 3 189 232, 3 580 432 und 3 987 942 angegeben.Known aerosol containers which are actuated by a release mechanism have the disadvantage that the actuation of their valve is not optimally easy, that part of the actuation mechanism protrudes beyond the circumference of the container, so that there is a risk of actuation of the trigger during transport or storage by an unintentional touch, and that they do not appear particularly aesthetic to the consumer. Known trigger actuated aerosol containers are disclosed in U.S. Patent Nos. 3,189,232, 3,580,432 and 3,987,942.

Bei der aus der FR-A-2 403 596 bekannten Ausgabehaube nach dem Oberbegriff des Patentanspruchs 1 ist das Auslöseglied mittels vertikaler Vorsprünge in Vertiefungen schwenkbar gelagert, die in der Unterseite horizontaler Gehäuseflansche ausgebildet sind. Das Auslöseglied stützt sich bei der Betätigung mit den freien oberen Enden zweier das Betätigungsglied seitlich einfassender Schenkel an der Unterseite der Flansche und mittels abgerundeter Unterkanten der Schenkel auf Schultern des Betätigungsgliedes ab. Bei der Schwenkbewgung des Auslösegliedes können daher die Vorsprünge aus den Vertiefungen ausrasten, so daß das Auslöseglied weiter in das Gehäuseglied gedrückt wird und nicht mehr geschwenkt werden kann.In the delivery hood known from FR-A-2 403 596 according to the preamble of claim 1, the trigger member is pivotally mounted by means of vertical projections in recesses which are formed in the underside of horizontal housing flanges. The actuating member is supported on actuation with the free upper ends of two legs that laterally enclose the actuating member on the underside of the flanges and by means of rounded lower edges of the legs on shoulders of the actuating member. When the trigger member is pivoted, the projections can therefore disengage from the recesses, so that the trigger member is pressed further into the housing member and can no longer be pivoted.

Darüber hinaus ist die zur Betätigung auf das Auslöseglied auszuübende Kraft verhältnismäßig groß.In addition, the force to be exerted on the trigger member to actuate is relatively large.

Bei der aus der GB-A-1 274 976 bekannten Ausgabehaube ist nur ein am Gehäuse schwenkbar gelagertes Betätigungsglied und kein zusätzliches Auslöseglied, das auf das Betätigungsglied einwirkt, vorgesehen. Am Betätigungsglied ist ein Schwenkzapfen ausgebildet, der in nach unten offenen Aussparungen des Gehäuses einrastbar ist. Bei unabsichtlicher Ausübung einer der normalen Betätigungsrichtung entgegengerichteten Kraft auf das Betätigungsglied, z.B. während des Transports, kann der Schwenkzapfen aus den Aussparungen ausrasten. Darüber hinaus ist auch hier eine verhältnismäßig hohe Betätigungskraft erforderlich.In the dispensing hood known from GB-A-1 274 976, only one actuating member pivotably mounted on the housing and no additional triggering member which acts on the actuating member is provided. A pivot pin is formed on the actuator and can be snapped into recesses in the housing that are open at the bottom. In the event of unintentional application of a force on the actuator, e.g. during transport, the pivot pin can snap out of the recesses. In addition, a relatively high actuation force is also required here.

Der Erfindung liegt die Aufgabe zugrunde, eine Ausgabehaube nach dem Oberbegriff des Anspruchs 1 anzugeben, die einen sicheren Halt des Auslösegliedes gewährleistet und leichter betätigbar ist.The invention has for its object to provide a dispensing hood according to the preamble of claim 1, which ensures a secure hold of the trigger member and is easier to operate.

Die erfindungsgemäße Lösung dieser Aufgabe ist im Patentanspruch 1 gekennzeichnet.The inventive solution to this problem is characterized in claim 1.

Die Ausbildung nicht nur des Auslösegliedes, sondern auch des Betätigungsgliedes als Hebel ergibt eine Mehrfach-Hebelwirkung mit entsprechender Verstärkung der Betätigungskraft, so daß eine Betätigung mit geringerer Kraft möglich ist. Hierbei gewährleistet nicht nur die geringere Betätigungskraft einen sicheren Halt des Auslösegliedes im Gehäuse, sondern auch die Ausbildung des Auslöseglied-Schwenklagers als Gelenk, da ein Gelenk eine allseitige Abstützung des gelenkigen Teils bewirkt.The formation not only of the trigger member but also of the actuating member as a lever results in a multiple lever action with a corresponding increase in the actuating force, so that actuation with less force is possible. Here, not only the lower actuating force ensures a secure hold of the release member in the housing, but also the formation of the release member pivot bearing as a joint, since a joint provides all-round support of the articulated part.

Weiterbildungen der erfindungsgemäßen Lösung sind in Unteransprüchen gekennzeichnet.Further developments of the solution according to the invention are characterized in the subclaims.

So kann die erfindungsgemäße Haube kompakt und ästhetisch ansprechend ausgebildet sein. Ihr Gehäuse kann einen Bodenteil aufweisen, der auf den mit einem Ventil versehenen Verschlußteil eines Aerosol-oder unter Innendruck stehenden Behälters paßt. Das Betätigungsglied kann in der Nähe der von der Ausgabeseite des Betätigungsgliedes entfernten Radialebene am Gehäuse angelenkt sein und das Auslöseglied am Betätigungsglied in der Nähe und im wesentlichen senkrecht zur Ausgaberichtung anliegen.The hood according to the invention can thus be compact and aesthetically pleasing. Your housing can have a bottom part which fits on the valve-provided closure part of an aerosol or container under internal pressure. The actuating member can be articulated on the housing in the vicinity of the radial plane remote from the output side of the actuating member, and the triggering member can rest on the actuating member in the vicinity and essentially perpendicular to the dispensing direction.

Das Gehäuse der erfindungsgemäßen Haube paßt vorzugsweise auf den Bördelrand des Behälters, der zwischen der Öffnung im Behälter und dem mit dem Ventil versehenen Verschluß ausgebildet ist, wobei der mit dem Ventil versehene Verschluß normalerweise eine tassenförmige Montagekappe bildet. Das Betätigungsglied kann einen vertikalen Teil, der dicht mit der Ausgabeseite des Ventils in dem Verschluß verbunden ist, und einen horizontalen Teil aufweisen, der in der Ausgabeöffnung endet. Der Ausgabekanal in dem Betätigungsglied kann mit dem Kanal oder Durchgang auf der Ausgabeseite des Ventils in Verbindung stehen, so daß sich ein geschlossener Kanal oder Durchgang ergibt, über den der Inhalt des Behälters zur Ausgabeöffnung geleitet wird. Durch das Anlenken des Betätigungsgliedes am Gehäuse, vorzugsweise diametral gegenüber dem Ausgabeende des Betätigungsgliedes, ergibt sich ein erster Hebel mit einem die ausgeübte Betätigungskraft aufnehmenden Hebelarm vom Gelenk bis zur Stelle der Ausübung des Arbeitsdrucks auf das Betätigungsglied, der länger als der Arbeitsarm von Gelenk bis zu demjenigen Teil des Betätigungsgliedes ist, der das Ventil berührt und niederdrückt (öffnet).The housing of the hood of the invention preferably fits the flanged edge of the container formed between the opening in the container and the valve closure, the valve closure normally forming a cup-shaped mounting cap. The actuator may have a vertical portion that is sealed to the discharge side of the valve in the closure and a horizontal portion that terminates in the discharge opening. The dispensing channel in the actuator may communicate with the channel or passage on the dispensing side of the valve to provide a closed channel or passage through which the contents of the container are directed to the dispensing opening. By articulating the actuator on the housing, preferably diametrically opposite the output end of the actuator, the result is a first lever with a lever arm absorbing the exerted actuating force from the joint to the point where the working pressure is exerted on the actuating member, which is longer than the working arm from the joint to the part of the actuating member which touches and depresses (opens) the valve.

Das Auslöseglied kann an dem horizontalen Teil des Betätigungsgliedes anliegen und sich nach unten und im wesentlichen senkrecht zu dem horizontalen Teil des Betätigungsgliedes erstrecken. Vorzugsweise ist das Auslöseglied relativ zum Ausgabeende des Betätigungsgliedes hinter der Anbringungs- oder Berührungsstelle am Gehäuse angelenkt, so daß sich ein zweiter Hebel ergibt. Bei dem zweiten Hebel ist der die ausgeübte Kraft aufnehmende Hebelarm, der durch den Abschnitt vom Gelenk des Auslösegleides bis zum Berührungspunkt des Auslöse- und Betätigungsgliedes gebildet wird (wo das Auslöseglied eine nach unten auf den horizontalen Teil des Betätigungsgliedes gerichtete Kraft ausüben kann), größer als der Arbeitsarm, der durch den Abschnitt vom Gelenkzwischen Auslöseglied und Gehäuse bis zu der Stelle gebildet wird, an der der vertikale Teil des Betätigungsgliedes das Ventil des Behälters berührt. Die auf die erfindungsgemäße Haube ausgeübte Betätigungskraft wird daher durch die Kombinationswirkung der beiden Hebel kumulativ verstärkt.The trigger member can abut the horizontal portion of the actuator and extend downward and substantially perpendicular to the horizontal portion of the actuator. Preferably, the trigger member is articulated relative to the output end of the actuator behind the attachment or contact point on the housing, so that a second lever results. With the second lever, the lever arm which absorbs the force exerted, which is formed by the section from the joint of the trigger slide to the point of contact of the trigger and actuating member (where the trigger member can exert a force directed downwards onto the horizontal part of the actuator), is larger as the working arm formed by the section from the hinge between the trigger member and the housing to the point where the vertical part of the actuator contacts the valve of the container. The actuating force exerted on the hood according to the invention is therefore cumulatively increased by the combination effect of the two levers.

Nach den Fig. 1 bis 3 hat die erfindungsgemäße Ausgabehaube 10 ein Gehäuse 12 mit hohlen Seitenwänden 14 und 16, die einen Schlitz 18 begrenzen, einer vertikalen Wand 20 (Fig. 3) und Vorderwänden 22 und 24, die ebenfalls den Schlitz 18 begrenzen. Die Seitenwände 14 und 16 des Gehäuses 12 haben an ihrem unteren Ende einen kreisförmigen Flansch 26, der in an sich bekannter Weise im Schnappsitz auf den herkömmlichen Bördelrand gesetzt werden kann, der durch die Verbindung der tassenförmigen Montagekappe 28 (Fig. 3) mit dem Öffnungsrand des unter Innendruck stehenden Behälters 30 (der in den Fig. 2 und 3, zum Teil schematisch, dargestellt ist) gebildet wird. Von der vertikalen Wand 20 erstrecken sich Rückwände 21 nach außen.1 to 3, the dispensing hood 10 according to the invention has a housing 12 with hollow side walls 14 and 16 which delimit a slot 18, a vertical wall 20 (FIG. 3) and front walls 22 and 24 which also delimit the slot 18. The side walls 14 and 16 of the housing 12 have at their lower end a circular flange 26 which, in a manner known per se, can be snap-fitted onto the conventional flanged rim, which is connected to the opening rim by connecting the cup-shaped mounting cap 28 (FIG. 3) of the pressurized container 30 (which is shown partially schematically in FIGS. 2 and 3) is formed. Rear walls 21 extend outward from the vertical wall 20.

Im Schlitz 18 des Gehäuses-12 ist ein Betätigungsglied 32 angeordnet. Das Betätigungsglied 32 hat einen horizontalen Teil 34 und einen vertikalen Teil 36. Durch den vertikalen Teil 36 des Betätigungsgliedes 32 verläuft ein Kanal 38, der sich in dem horizontalen Teil 34 als Kanal 40 fortsetzt. An dem einen Ende des vertikalen Teils 36 des Betätigungsgliedes 32 ist eine Ventilschaft-Aufnahmefassung 42 ausgebildet, die eine Vertiefung zur Aufnahme des Ventilschaftes 44 eines herkömmlichen Ventils des unter Innendruck stehenden Behälters bildet. Das eine Ende des horizontalen Teils 34 des Betätigungsgliedes 32 bildet ein Zapfen 46 zur Aufnahme eines Einsatzes 48 mit einer Ausgabeöffnung 50.In the slot 18 of the housing-12, an actuator 32 is arranged. The actuator 32 has a horizontal part 34 and a vertical part 36. A channel 38 runs through the vertical part 36 of the actuator 32 and continues in the horizontal part 34 as a channel 40. At one end of the vertical part 36 of the actuator 32, a valve stem receiving socket 42 is formed which forms a recess for receiving the valve stem 44 of a conventional valve of the container under internal pressure. One end of the horizontal part 34 of the actuator 32 forms a pin 46 for receiving an insert 48 with a dispensing opening 50.

Der Zapfen 46 und der Einsatz 48 können in an sich bekannter Weise ausgebildet sein, vorzugsweise als Ausgabesystem mit mehreren Kanälen, die zur Ausgabeöffnung führen, üblicherweise als "Wirbelkammer" bezeichnet.The pin 46 and the insert 48 can be designed in a manner known per se, preferably as a dispensing system with a plurality of channels which lead to the dispensing opening, usually referred to as a "swirl chamber".

Von der Verbindung des horizontalen Teils 34 mit dem vertikalen Teil 36 des Betätigungsgliedes 32 erstreckt sich ein Gelenkarm 52 weg, der in einem Gelenk 54 endet.An articulated arm 52, which ends in an articulation 54, extends away from the connection of the horizontal part 34 to the vertical part 36 of the actuating member 32.

Das Gehäuse 12 und das Betätigungsglied 32 sind vorzugsweise einteilig aus Kunststoff geformt, wobei das Gelenk 54 einteilig mit dem Gehäuse 12 hergestellt wird.The housing 12 and the actuator 32 are preferably formed in one piece from plastic, the joint 54 being produced in one piece with the housing 12.

Die Bewegungsbahn des Betätigungsgliedes beim Öffnen eines in an sich bekannter Weise vertikal zu betätigenden Aerosol-Ventils sollte möglichst gleich der des Ventilschaftes sein, nämlich vertikal. Um diese Bewegungsrichtung des Betätigungsgliedes beim Öffnen des Ventils zu erreichen, ist das Gelenk zwischen Betätigungsglied und Gehäuse in eine Ebene gelegt, die sich radial vom oberen Ende des Ventilschaftes nach außen erstreckt, vorzugsweise in die Mitte des vom Ventilschaft bei der Betätigung zurückgelegten Weges.The movement path of the actuating member when opening an aerosol valve to be actuated vertically in a manner known per se should be as close as possible to that of the valve stem, namely vertically. In order to achieve this direction of movement of the actuator when the valve is opened, the joint between the actuator and the housing is placed in a plane which extends radially outward from the upper end of the valve stem, preferably in the middle of the path covered by the valve stem during actuation.

Das Auslöseglied 56 (siehe insbesondere Fig. 1) hat einen Jochteil 58 mit einer Deckplatte 60 und Seitenwänden 62 und 64. Auf beiden Seitenwänden 62 und 64 sind Zapfen 66 vorgesehen. Das Auslöseglied 56 hat einen Fingeraufnahmeteil 68, dessen Oberseite eine genutete Platte 70 aufweist. Der Jochteil 58 begrenzt eine Öffnung 72, die so bemessen ist, daß der Jochteil 58 mit der Öffnung 72 auf den horizontalen Teil 34 des Betätigungsgliedes 32 paßt und auf diesem gleitend verschiebbar ist.The trigger member 56 (see in particular FIG. 1) has a yoke part 58 with a cover plate 60 and side walls 62 and 64. Pins 66 are provided on both side walls 62 and 64. The trigger member 56 has a finger receiving part 68, the top of which has a grooved plate 70. The yoke part 58 delimits an opening 72 which is dimensioned such that the yoke part 58 with the opening 72 fits onto the horizontal part 34 of the actuating member 32 and is slidably displaceable thereon.

Die genutete Platte 70 stellt ein weiteres Merkmal der Erfindung dar: sie bildet einen Auffangkanal für herabfallende Tropfen des aus dem Behälter ausgegebenen Erzeugnisses nach dem Schließen des Ventils. Das auf die Platte 70 herabtropfende Erzeugnis läuft längs der Nut in das Innere der Ausgabehaube, statt vom Behälter herab oder auf die Hand des Benutzers zu tropfen.The grooved plate 70 represents another feature of the invention: it forms a collection channel for falling drops of the product dispensed from the container after the valve is closed. The product dripping onto the plate 70 runs along the groove in the inside of the dispensing hood instead of dripping down from the container or onto the user's hand.

Bei der Montage des Auslösegliedes 56 am Betätigungsglied 32 werden die Zapfen 66 in Nuten 74 auf den Innenseiten der hohlen Seitenwände 14 und 16 entlanggeführt. Die Nuten 74 divergieren geringfügig zum Ausgabeende des Betätigungsgliedes 32 hin. Sie enden in Vertiefungen 76, die tiefer als die inneren Enden der Nuten 74 sind, so daß, wenn das Auslöseglied 56 bis in seine Endlage jenseits der Nuten 74 eingeführt worden ist, die Zapfen 66 in den Vertiefungen 76 einrasten und das Auslöseglied 56 in dieser Einbaulage festhalten.When the trigger member 56 is mounted on the actuating member 32, the pins 66 are guided along in grooves 74 on the inner sides of the hollow side walls 14 and 16. The grooves 74 diverge slightly toward the output end of the actuator 32. They end in recesses 76, which are deeper than the inner ends of the grooves 74, so that when the trigger member 56 has been inserted into its end position beyond the grooves 74, the pins 66 engage in the recesses 76 and the trigger member 56 in this Hold the installation position.

Wie Fig. 2 zeigt, schließt das vordere Ende des Jochteils 58 mit den Vorderwänden 22 und 24 des Gehäuses 12 ab.As shown in FIG. 2, the front end of the yoke part 58 closes with the front walls 22 and 24 of the housing 12.

Die Zapfen 66 wirken als Gelenk für das Auslöseglied, so daß es als zweiter Hebel wirkt, wenn das Auslöseglied 56 in Richtung auf den Behälter bewegt wird.The pins 66 act as a hinge for the trigger member so that it acts as a second lever when the trigger member 56 is moved toward the container.

Die maximale Hebelwirkung des Auslösegliedes wird dadurch erreicht, daß das Gelenk des Auslösegliedes so dicht wie möglich, d.h. wie es die Herstellung im Spritzgußverfahren und der Zusammenbau gestatten, am entgegenwirkenden Druck des Ventils des unter Innendruck stehenden Behälters und von der Berührungsstelle zwischen Auslöseglied und Betätigungsglied entfernt angeordnet wird.The maximum leverage of the trip member is achieved by making the trip member hinge as tight as possible, i.e. how it allows the production in the injection molding process and the assembly, is arranged at the counteracting pressure of the valve of the container under internal pressure and away from the point of contact between the trigger member and the actuator.

Wenn das Auslöseglied in Richtung auf den Behälter bewegt wird, wird das Betätigungsglied und dadurch der Ventilschaft nach unten gedrückt, so daß das Ventil des Behälters geöffnet wird. Der Behältereinhalt wird dann über die Kanäle 38, 40 zur "Wirbelkammer" am Ausgabeende des horizontalen Teils 34 des Betätigungsgliedes 32 und schließlich zur Ausgabeöffnung 50 ausgegeben.When the trigger member is moved toward the container, the actuator and thereby the valve stem is pushed down so that the valve of the container is opened. The container contents are then discharged via the channels 38, 40 to the "swirl chamber" at the discharge end of the horizontal part 34 of the actuator 32 and finally to the discharge opening 50.
