Description

Die Erfindung bezieht sich auf eine Austeilerkapsel für Aerosolbehälter gemäß dem Oberbegriff des Anspruches 1.The invention relates to a dispenser capsule for aerosol containers according to the preamble of claim 1.

Eine derartige Austeilerkapsel ist aus dem DE-U-81 06 470 bekannt. Die dort beschriebene Konstruktion hat sich in der Praxis sowohl fertigungstechnisch als auch handhabungstechnisch hervorragend bewährt.Such a dispenser capsule is known from DE-U-81 06 470. The construction described there has proven itself in practice both in terms of production technology and handling technology.

Bei der bekannten Austeilerkapsel wird jedoch im rohrförmigen Ansatz ein unnötiger Fluidraum geschaffen, aus dem nach Beendigung des Sprühvorgangs, also nach Loslassen der Betätigungs taste, sich noch befindlicher Behälterinhalt aussprüht. Dieses unkontrollierte "Nachsprühen" wird als unangenehm empfunden und ist daher unerwünscht. Ferner tritt bei der Austeilerkapsel das Problem auf, daß bei Betätigung der Betätigungstaste der Sprühvorgang erst nach Ausfüllung des rohrförmigen Ansatzes sowie des Zuführungskanals beginnt, also mit nicht beachtlicher zeitlicher Verzögerung gegenüber der Betätigung der Betätigungstaste.In the known dispenser capsule, however, an unnecessary fluid space is created in the tubular attachment, from which, after the spraying process has ended, that is to say after the actuating button has been released, the container contents which are still being sprayed out. This uncontrolled "spraying" is perceived as unpleasant and is therefore undesirable. Furthermore, the problem with the dispenser capsule is that when the actuation button is actuated, the spraying process only begins after the tubular extension and the feed channel have been filled, that is to say with a noticeable time lag compared to the actuation of the actuation button.

Zum anderen hat der bekannte rohrförmige Ansatz fertigungstechnische Probleme zur Folge. Aufgrund der durch den rohrförmigen Ansatz bedingten Werkstoffmasse ist eine relativ lange Kühlzeit erforderlich, bevor das Kapselgehäuse aus der Spritzform entfernt werden kann. Der Nutzungsgrad der Spritzgießmaschine ist entsprechend beschränkt.On the other hand, the known tubular approach results in manufacturing problems. Due to the material mass caused by the tubular attachment, a relatively long cooling time is required before the capsule housing can be removed from the injection mold. The degree of utilization of the injection molding machine is limited accordingly.

Schließlich hat der bekannte rohrförmige Ansatz noch den Nachteil, daß die Einwirkung auf das Ventilröhrchen beim Kippen der Betätigungstaste um die Gelenkverbindung sehr ungünstig ist. Durch den dem rohrförmigen Ansatz entsprechend langen Hebelarm wird das Ventilröhrchen seitlich stark belastet, worunter die Dichtigkeit zwischen dem rohrförmigen Ansatz und dem Ventilröhrchen sowie dessen Lagerung im Behälterdeckel sehr leicht beschädigt werden kann.Finally, the known tubular approach has the disadvantage that the action on the valve tube when tilting the actuation button around the articulation is very unfavorable. Due to the long lever arm corresponding to the tubular extension, the valve tube is heavily loaded laterally, under which the tightness between the tubular extension and the valve tube and its storage in the container lid can be easily damaged.

Auch aus den GB-A-1 467 847 und GB-A-2 077 860, sind gattungsgemäße Austeilerkapseln für Aerosolbehälter bekannt. Diese Austeilerkapseln sind bezüglich der Ausbildung des Zuführungskanals und des rohrförmigen Ansatzes prinzipiell ähnlich aufgebaut wie die Austeilerkapsel nach dem vorgenannten Gebrauchsmuster, so daß auch bei diesen bekannten Austeilerkapseln die im Vorhergehenden geschilderten Probleme auftreten.Generic dispenser capsules for aerosol containers are also known from GB-A-1 467 847 and GB-A-2 077 860. These dispenser capsules are basically constructed similarly to the dispenser capsule according to the aforementioned utility model with regard to the design of the feed channel and the tubular extension, so that the problems described above also occur with these known dispenser capsules.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile der bekannten Austeilerkapsel zu vermeiden, insbesondere die Austeilerkapsel hinsichtlich einer Ansprache auf Betätigung zu verbessern.The present invention is based on the object of avoiding the disadvantages of the known distributor capsule, in particular improving the distributor capsule with regard to a response to actuation.

Diese Aufgabe wird erfindungsgemäß in überraschend einfacher Weise durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.This object is achieved in a surprisingly simple manner by the characterizing features of claim 1.

Durch diese konstruktive Maßnahme wird eine minimale Baulänge des rohrförmigen Ansatzes erreicht. Der rohrförmige Ansatz kann im Extremfall die Form einer Kappe haben, und zwar dann, wenn sich die Auslaßöffnung des im Deckel des Aerosolbehälters gelagerten Ventilröhrchens im geschlossenen Zustand desselben knapp unterhalb des Zuführungskanals befindet. Dadurch ist der durch den Zuführungskanal und den rohrförmigen Ansatz gebildete Fluidraum ein Minimum. Es tritt praktisch kein unerwünschtes "Nachsprühen" nach Loslassen der Betätigungstaste mehr auf. Auch ist die zeitliche Verzögerung beim Beginn des Sprühvorganges minimal. Vor allem ist die seitliche Einwirkung des rohrförmigen Ansatzes auf das Ventilröhrchen beim Betätigen bzw. Kippen der Betätigungstaste um die Gelenkverbindung minimal, so daß keine Dichtigkeitsprobleme zwischen rohrförmigem Ansatz und Ventilröhrchen mehr auftreten. Es besteht auch nicht mehr die Gefahr einer Beschädigung des Ventilröhrchens oder dessen Lagerung im Behälterdeckel durch den rohrförmigen Ansatz. Schließlich ist bei der erfindungsgemäßen Ausbildung der Austeilerkapsel der Materialeinsatz reduziert, vor allem im Bereich des zentral angeordneten rohrförmigen Ansatzes mit der Folge einer verringerten Kühlzeit und einer höheren Ausstoßrate der Spritzgießmaschine.This constructive measure achieves a minimum overall length of the tubular extension. In extreme cases, the tubular extension can have the shape of a cap, specifically when the outlet opening of the valve tube mounted in the lid of the aerosol container is located just below the feed channel in the closed state of the same. As a result, the fluid space formed by the feed channel and the tubular extension is a minimum. There is practically no undesired "spraying" after releasing the actuation button. The time delay at the start of the spraying process is also minimal. Above all, the lateral action of the tubular extension on the valve tube when actuating or tilting the actuation button around the articulated connection is minimal, so that there are no more sealing problems between the tubular extension and the valve tube. There is also no longer any risk of damage to the valve tube or its storage in the container lid due to the tubular extension. Finally, in the configuration of the dispenser capsule according to the invention, the use of materials is reduced, especially in the area of the centrally arranged tubular attachment, with the result of a reduced cooling time and a higher ejection rate of the injection molding machine.

Vorzugsweise weist die Betätigungstaste oberhalb des sich etwa quer zur Kapsellängsachse erstreckenden Zuführungskanals eine bis zu diesem reichende Ausnehmung auf. Diese Ausnehmung hat vor allem fertigungstechnische Vorteile, da dadurch Hinterschneidungen zur Vermeidung von Materialanhäufungen vermieden werden können. Die Ausnehmung ist vorteilhafterweise entsprechend Anspruch 4 dimensioniert und entsprechend Anspruch 5 ausgebildet.Preferably, the actuation button has a recess extending up to this above the feed channel which extends approximately transversely to the longitudinal axis of the capsule. This recess has particular advantages in terms of production technology, since it enables undercuts to be avoided to avoid material accumulation. The recess is advantageously dimensioned according to claim 4 and designed according to claim 5.

Die Gelenkverbindung zwischen der Betätigungstaste und dem Kapselgehäuse kann entsprechend dem DE-U-81 06 470 ausgebildet sein. Die Ausbildung gesonderter Gelenkstege kann jedoch vermieden werden, wenn die die Austeilerdüse aufweisende Vorderwand der Betätigungstaste unter Ausbildung der Gelenkverbindung zwischen derselben und dem Kapselgehäuse als Fortsetzung der Kapselwand ausgebildet ist derart, daß eine sich etwa quer zur Kapsellängsachse erstreckende Gelenkachse im Übergangsbereich zwischen Vorderwand der Betätigungstaste und der Kapselwand entsteht, wie sie in ähnlicher Weise der GB-A-2 077 860 entnehmbar ist. Diese Gelenkverbindung ist fertigungstechnisch erheblich problemloser als die Ausbildung von Gelenkstegen entsprechend dem DE-U- 81 06 470. Vor allem kann das Spritzgieß-Werkzeug entsprechend einfacher gestaltet werden.The articulated connection between the actuation button and the capsule housing can be designed in accordance with DE-U-81 06 470. The formation of separate joint webs can, however, be avoided if the front wall of the actuating button, which has the dispensing nozzle, is formed as a continuation of the capsule wall by forming the articulated connection between the same and the capsule housing such that an articulated axis extending approximately transversely to the longitudinal axis of the capsule in the transition region between the front wall of the actuating button and the capsule wall is formed, as can be seen in a similar manner from GB-A-2 077 860. This articulated connection is considerably easier in terms of production technology than the formation of articulated webs in accordance with DE-U-81 06 470. Above all, the injection molding tool can be made correspondingly simpler.

Im übrigen werden bei der Erfindung die Vorteile der Austeilerkapsel nach dem DE-U-81 06 470 in vollem Umfange beibehalten. Diese Vorteile sind darin zu sehen, daß durch die einstückige Herstellung von Betätigungstaste und Kapselgehäuse in fertigungstechnischer Hinsicht eine Vereinfachung erreicht wird. Darüber hinaus ergibt sich in bedienungstechnischer und funktioneller Hinsicht eine Vereinfachung gegenüber dem übrigen Stand der Technik, da bei Ingebrauchnahme zusätzliche Abdeckungen für die Betätigungstaste nicht mehr entfernt werden müssen und ein Trennen von Betätigungstaste und Kapselgehäuse nicht mehr erforderlich ist.Otherwise, the advantages of the dispenser capsule according to DE-U-81 06 470 are retained in full in the invention. These advantages can be seen in the fact that the one-piece production of the actuation button and capsule housing simplifies the manufacturing process. In addition, there is a simplification in terms of operation and functionality compared to the rest of the prior art, since additional covers for the Actuation button no longer need to be removed and it is no longer necessary to separate the actuation button and capsule housing.

Im folgenden wird eine bevorzugte Ausführungsform einer erfindungsgemäß ausgebildeten Austeilerkapsel anhand der beigefügten Zeichnung näher erläutert. Es zeigen:

A preferred embodiment of a dispenser capsule designed according to the invention is explained in more detail below with reference to the attached drawing. Show it:
  • Figure 1 shows the front or spray side of a dispenser capsule designed according to the invention in a perspective view.
  • FIG. 2 shows the rear of the dispenser capsule according to FIG. 1 in a perspective view;

Die in den Figuren dargestellte Austeilerkapsel ist für Aerosolbehälter 10 bestimmt, die aus Aluminium-, vorzugsweise Weißblech, hergestellt sein können. Die Austeilerkapsel besitzt ein im wesentlichen zylindrisches Kapselgehäuse 1, an dem einteilig eine Betätigungstaste 2 ausgeformt ist. Die Betätigungstaste 2 ist in einer sich quer über die Oberfläche erstreckenden Ausnehmung 3 des zylindrischen Kapselgehäuses 1 angeordnet. Die Betätigungstaste umfaßt einen zentralen rohrförmigen Ansatz 6, der in oder auf Ventilröhrchen 11 des Aerosolbehälters 10 ein bzw. aufsetzbar ist, eine Austeilerdüse 8 und einen an dieser einerseits und an den rohrförmigen Ansatz 6 andererseits angeschlossenen Zuführungskanal 7 für den auszuteilenden Behälterinhalt, z.B. Flüssigkeit. Die Betätigungstaste 2 ist mit dem Kapselgehäuse 1 an ihrem rückwärtigen Ende mittels Sollbruchstellen aufweisender Trennstege 5 und am anderen Ende über eine Gelenkverbindung 4 verbunden. Die Gelenkverbindung 4 wird dadurch gebildet, daß die die Austeilerdüse 8 aufweisende Vorderwand 14 der Betätigungstaste 2 als Fortsetzung der Kapselwand 15 gestaltet ist, derart, daß eine sich etwa quer zur Kapsellängsachse 12 erstreckende Gelenkachse im Übergangsbereich zwischen Vorderwand 14 der Betätigungstaste 2 und der Kapselwand 15 entsteht.The dispenser capsule shown in the figures is intended for aerosol containers 10, which can be made of aluminum, preferably tinplate. The dispenser capsule has an essentially cylindrical capsule housing 1, on which an actuation button 2 is formed in one piece. The actuation button 2 is arranged in a recess 3 of the cylindrical capsule housing 1 which extends across the surface. The actuation button comprises a central tubular extension 6 which can be inserted or placed in or on valve tubes 11 of the aerosol container 10, a dispensing nozzle 8 and a supply channel 7 connected to this on the one hand and to the tubular extension 6 on the other hand for the contents of the container to be distributed, e.g. Liquid. The actuation button 2 is connected to the capsule housing 1 at its rear end by means of separating webs 5 having predetermined breaking points and at the other end via an articulated connection 4. The articulated connection 4 is formed in that the front wall 14 of the actuating button 2, which has the dispensing nozzle 8, is designed as a continuation of the capsule wall 15, such that an articulated axis extending approximately transversely to the longitudinal axis 12 of the capsule in the transition region between the front wall 14 of the actuating button 2 and the capsule wall 15 arises.

Bei Druckbeaufschlagung der Betätigungstaste 2 werden die Trennstege 5 durchbrochen und die Betätigungstaste 2 aus einer Lage entsprechend Fig. 3 in eine Lage entsprechend Fig. 4 nach unten um die oben definierte Gelenkachse 16 gekippt, Die Trennstege 5 zeigen gleichzeitig an, ob eine unbefugte Benutzung des Inhaltes des Aerosolbehälters stattgefunden hat oder nicht.When pressure is applied to the actuating button 2, the separating webs 5 are broken and the actuating button 2 is tilted downward from a position corresponding to FIG. 3 into a position corresponding to FIG. 4 about the hinge axis 16 defined above. The separating webs 5 simultaneously indicate whether unauthorized use of the Content of the aerosol container has taken place or not.

Die oben erwähnte Austeilerdüse 8, an der der Zuführungskanal 7 angeschlossen ist, ist in einer üblichen, in der Vorderwand 14 der Betätigungstaste 2 vorgesehenen Ausnehmung untergebracht.The above-mentioned distributor nozzle 8, to which the feed channel 7 is connected, is accommodated in a conventional recess provided in the front wall 14 of the actuation button 2.

Zur Befestigung der Austeilerkapsel an einem Aerosolbehälter 10 ist das Kapselgehäuse 1 im Bereich seines unteren Randes mit Rastvorsprüngen 9 versehen, welche elastisch mit besonderen am Aerosolbehälter oder am Ventilröhrchen 11 angeordneten Ausnehmungen wechselwirken.To attach the dispenser capsule to an aerosol container 10, the capsule housing 1 is provided in the region of its lower edge with locking projections 9 which interact elastically with special recesses arranged on the aerosol container or on the valve tube 11.

Wie die Fig. 3 und 4 erkennen lassen, wird bei Druckbeaufschlagung bzw. beim Betätigen der Betätigungstaste 2 das aus dem Deckel des Aerosolbehälters 10 herausragende Ventilröhrchen 11 in den Behälter hineingedrückt, wodurch in an sich bekannter Weise das im Behälterdeckel angeordnete Ventil geöffnet wird, so daß durch das Ventilröhrchen 11 Flüssigkeit unter Druck aus dem Behälter 10 austreten kann. Wie die Fig. 3 und 4 ferner erkennen lassen, ist durch die Anordnung des Zuführungskanals 7 unmittelbar oberhalb der Gelenkverbindung 4 bzw. Gelenkachse 16 die Baulänge des zentral angeordneten rohrförmigen Ansatzes 6 minimal. Der rohrförmige Ansatz 6 ist zu einer über die Auslaßöffnung des Ventilröhrchens 11 gestülpten Kappe reduziert. Die dadurch erhaltenen Vorteile sind einleitend ausführlich dargelegt. Es wird auf die entsprechenden Ausführungen verwiesen.As can be seen in FIGS. 3 and 4, the valve tube 11 protruding from the lid of the aerosol container 10 is pressed into the container when pressure is applied or the actuation button 2 is pressed, whereby the valve arranged in the container lid is opened in a manner known per se, so that liquid can escape from the container 10 under pressure through the valve tube 11. As can also be seen in FIGS. 3 and 4, the overall length of the centrally arranged tubular extension 6 is minimal due to the arrangement of the feed channel 7 directly above the articulated connection 4 or articulated axis 16. The tubular extension 6 is reduced to a cap placed over the outlet opening of the valve tube 11. The advantages thus obtained are explained in detail in the introduction. Reference is made to the corresponding explanations.

Oberhalb des sich etwa quer zur Kapsellängsachse 12 erstreckenden Zuführungskanals 7 weist die Betätigungstaste 2 eine bis zum Zuführungskanal 7 reichende Ausnehmung 13 auf. Die lichte Weite der Ausnehmung 13 entspricht etwa dem Außendurchmesser des Zuführungskanals 7, Die Längserstreckung der Ausnehmung 13 entspricht etwa der Länge des Zuführungskanals 7 plus mittlerer Durchmesser des rohrförmigen Ansatzes 6. Bei dem hier dargestellten Ausführungsbeispiel ist die Ausnehmung 13 nur nach oben offen ausgebildet. Sie könnte zusätzlich nach vorne oder nur nach vorne offen ausgebildet sein. Die hier etwa spaltartig ausgebildete Ausnehmung 13 wird durch ein entsprechendes schwertartiges Teil des Spritzgieß-Werkzeuges erhalten, wobei dieses Teil mit Kühlkanälen versehen ist zur zusätzlichen Reduzierung der Verweilzeit der Austeilerkapsel im Spritzgieß-Werkzeug. Durch diese Maßnahme läßt sich die Ausstoßrate im Vergleich zu der bekannten Ausführungsform um etwa 25 bis 30% steigern. Diese Steigerung schlägt bei den hier üblichen Millionenstückzahlen pro Jahr ganz erheblich zu Buche. Darüberhinaus läßt sich durch die erfindungsgemäßen Maßnahmen auch der Materialeinsatz im Vergleich zu der bekannten Ausführungsform nach dem DE-GM 8 106 470 nicht unbeachtlich reduzieren.Above the feed channel 7, which extends approximately transversely to the longitudinal axis 12 of the capsule, the actuation button 2 has a recess 13 which extends as far as the feed channel 7. The clear width of the recess 13 corresponds approximately to the outer diameter of the feed channel 7, the longitudinal extent of the recess 13 corresponds approximately to the length of the feed channel 7 plus the average diameter of the tubular extension 6. In the embodiment shown here, the recess 13 is only open at the top. It could also be designed to be open towards the front or only towards the front. The recess 13, which is approximately gap-shaped here, is obtained by a corresponding sword-like part of the injection molding tool, this part being provided with cooling channels for additionally reducing the dwell time of the distributor capsule in the injection molding tool. This measure allows the ejection rate to be increased by approximately 25 to 30% compared to the known embodiment. This increase has a significant impact on the usual millions of units per year. In addition, the use of materials in comparison with the known embodiment according to DE-GM 8 106 470 cannot be reduced insignificantly by the measures according to the invention.

Die Austeilerkapsel kann in Bezug auf ihre Abmessungen und entsprechend den Erfordernissen auf einfache Weise den unterschiedlichsten Aerosolbehältern angepaßt werden. Dies gilt auch für die nach innen ragenden Rastvorsprünge 9 im Bereich des unteren Randes des Kapselgehäuses 1.The dispenser capsule can be easily adapted to a wide variety of aerosol containers in terms of its dimensions and according to requirements. This also applies to the inwardly projecting locking projections 9 in the area of the lower edge of the capsule housing 1.
