Abstract

Metering devices, particularly for adhesives and sealants, that can be placed on a flexible container by means of an adapted ring, a lever being connected to the ring, and pressing against the container, are known. The invention relates to a metering device whereon the lever is connected to the ring via a deformable spring plate. A push button is formed onto the lever as an extension. Thus, the one-piece metering device is inexpensive and can be produced without needing to be assembled.

Description

Dosiervorrichtung metering
Die vorliegende Erfindung betrifft eine Dosiervorrichtung zur Befestigung an einem Behalter, der einen Boden und einen oberhalb einer Behalterschulter angeformten Behalterhals aufweist, auf den ein Verschluss mit Aufgusstulle aufsetzbar ist, gemass Oberbegriff des Patentanspruches 1.The present invention relates to a metering device for attachment to a container having a bottom and a Behalterhalter above a Behalterschulter molded on a closure with Aufgusstulle can be placed, according to the preamble of claim 1.
Solche Dosiervorrichtungen werden insbesondere auch benotigt für Klebstoffe, Cyanacrylate Sekundenkleber oder anaerobe Kleb- und Dichtstoffe. Diese werden in flaschenformige Behalter angeboten, wobei all diese Kleb- und Dichtstoffe nur in Kleinstmengen dosiert abgegeben werden und entsprechend auch die Behalter, nämlich Kunststoffflaschen, relativ klein sind. Zur dosierten Abgabe aus einer entsprechenden Tülle, muss der Behalter leicht gequetscht werden. Besonders Kleb- und Dichtstoffe sind oft zähflüssig beziehungsweise niedrig viskos und fHessen daher nicht selbständig aus. Gleichzeitig aber müssen gewisse Klebstoffe so aufbewahrt werden, dass praktisch kein Sauerstoffzutritt erfolgen kann.

Accordingly, in order to still allow a reasonable dosable Klebstoffabgäbe to provide the container with a metering device.
Bereits aus der US-A-4 , 771, 769 ist eine Dosiervorrichtung bekannt, bei der eine relativ kleine Flasche in eine Vorrichtung einsetzbar ist, die einen Körper aufweist in dem die Flasche sich befindet und dieser Körper besitzt einen an der Wandung angelenkten Druckhebel, der am Rand auf den Boden der Flasche drückt. Diese Lösung ist praktisch nur für weiche Behälter überhaupt denkbar, denn bei Kunststoffflaschen aus einem harten Kunststoff insbesondere einem HDPE ist gerade im Bereich der besonders grossen Wandstärke im Uebergang von Boden zur Mantelwand eine Verformung praktisch nicht möglich. Hinzu kommt, dass zur Aufnahme der Flasche im Dosiergerät die Kappe abgeschraubt werden muss, das offene Behältnis in die Vorrichtung eingebracht und danach die Kappe wieder aufgesetzt werden um überhaupt die Flasche in die Vorrichtung haltend zu befestigen. Dieses Vorgehen wäre für einUS Pat. No. 4,771,769 discloses a metering device in which a relatively small bottle can be inserted into a device which has a body in which the bottle is located and this body has a pressure lever articulated on the wall. who pushes the bottom of the bottle on the edge.

Eine wesentlich kostengünstigere Variante zeigt die WO- 2004/013009-A. Hier ist eine einfache, kostengünstige Dosiervorrichtung aufgezeigt mittels der eine tropfenweise Abgabe einer Flüssigkeit erreichbar ist. Das Dokument zeigt eine Vielzahl von Ausfuhrungsbeispielen, wobei jedoch hier lediglich eine Ausfuhrungsform von Bedeutung ist, bei der eine schlaufenformige, parallel zur Flaschenlangsachse ausgerichtete Kunststoffschlaufe vorgeschlagen wird, bei der der Behalterhals durch diese Schlaufe hindurchgefuhrt ist. Die Schlaufe ist im Bodenbereich der Flasche getrennt und liegt hier am Boden der Flasche an, lauft dann der Mantelwand anliegend nach oben bis zum Flaschenhals, verlauft auf der Behalterschulter aufliegend über die Flasche hinweg und verlauft danach auf dem diametral gegenüberliegenden Flaschenwandbereich in einem gewissen eingeformten Knick nach unten. Der Knick im Bereich der Flaschenschulter liegt auf der Mantelwand auf und ein Hebel lauft von der Schulter zum Boden hin abgewinkelt nach unten, um von dort nochmals geknickt wiederum zur Schlaufe zu gelangen, die unter dem Flaschenboden hindurch verlauft. Eine solche Vorrichtung hat wiederum den Nachteil, dass der Druck genau dort ausgeübt wird, wo die Flasche eine besonders hohe Steifigkeit aufweist, nämlich im Bereich der Schulter. Des weiteren ist diese Vorrichtung nur zum zeitweisen Gebrauch geeignet undA substantially less expensive variant is shown in WO 2004/013009-A. Here is a simple, inexpensive metering device is shown by means of which a dropwise delivery of a liquid can be achieved. The document shows a variety of exemplary embodiments, but here only one embodiment of importance, in which a loop-shaped, parallel to the bottle longitudinal axis aligned plastic loop is proposed, in which the Behalterhals is passed through this loop. The loop is separated in the bottom area of the bottle and is here at the bottom of the bottle, then runs the mantle wall fitting up to the neck, runs on the Behalterschulter overlying the bottle and then runs on the diametrically opposite bottle wall area in a certain molded kink downward. The kink in the area of the bottle shoulder rests on the mantle wall and a lever runs downwards from the shoulder to the bottom, from where it kinks once again to the loop which runs underneath the bottom of the bottle. Such a device in turn has the disadvantage that the pressure is exerted exactly where the bottle has a particularly high rigidity, namely in the region of the shoulder. Furthermore, this device is only suitable for temporary use and
_ 2 „ will man den Behalter abstellen, so muss im Prinzip die Vorrichtung von der Flasche gelost werden._ 2 " if you want to turn off the container, so in principle the device must be solved by the bottle.
Schliesslich ist aus der US-4 773 898 eine Dosiervorrichtung gemass dem Oberbegriff des Patentanspruches 1 bekannt. Es handelt sich hierbei um eine veterinärmedizinischeFinally, from US-4 773 898 a metering device according to the preamble of claim 1 is known. It is a veterinary
Vorrichtung zur Verabreichung von Medikamenten an einem Tier.Device for administering medicaments to an animal.
Am auf die Flasche aufgesetzten Ring ist über ein Scharnier ein Hebel angelenkt, der eine zur Flasche hin gerichtete Krümmung aufweist, der als Drucker wirkt.On the ring attached to the bottle, a lever is articulated via a hinge, which has a directed towards the bottle curvature, which acts as a printer.
Es ist die Aufgabe der vorliegenden Erfindung, eine Dosiervorrichtung zu schaffen, die insbesondere für längliche zylindrische Behalter, insbesondere stiftformige Behalter, geeignet ist und die Nachteile der beschriebenen Losungen meidet und einteilig scharnierfrei und somit kostengünstig herstellbar ist.It is the object of the present invention to provide a metering device which is particularly suitable for elongated cylindrical container, in particular pen-shaped container, and avoids the disadvantages of the solutions described and is one piece hinges and thus inexpensive to produce.
Diese Aufgabe lost eine Dosiervorrichtung mit den Merkmalen des Patentanspruches 1. Weitere vorteilhafte Ausgestaltungsformen des Erfindungsgegenstandes gehen aus den abhängigen Patentansprüchen hervor.This object is achieved by a metering device with the features of claim 1. Further advantageous embodiments of the subject invention will become apparent from the dependent claims.
In der anliegenden Zeichnung ist eine bevorzugte Ausführungsform dargestellt und nachfolgend detailliert beschrieben. Es zeigt: Figur 1 eine perspektivische Ansicht der Dosiervorrichtung befestigt auf einen länglichen, stiftförmigen Behälter in perspektivischer Ansicht mit Blick auf die Standfläche des Behältnisses beziehungsweise der Dosiervorrichtung.In the accompanying drawings, a preferred embodiment is shown and described in detail below. It shows: Figure 1 is a perspective view of the metering device mounted on an elongated, pin-shaped container in a perspective view overlooking the base of the container or the metering device.
Figur 2 zeigt dieselbe Dosiervorrichtung auf demselben Behälter mit Blick auf den tüllenförmigen Ausguss undFigure 2 shows the same metering device on the same container with a view of the nozzle-shaped spout and
Figur 3 einen zentrischen Vertikalschnitt durch die Dosiervorrichtung und den Behälter an den sie sich hält.Figure 3 shows a central vertical section through the metering device and the container to which it holds.
In den Figuren sind jeweils drei verschiedene Elemente ersichtlich. Mit 1 ist die eigentliche Dosiervorrichtung gezeichnet, während der Behälter mit 2 und der Verschluss mit 3 bezeichnet ist. Der Behälter 2 ist in einem axialen Längsschnitt in der Figur 3 am deutlichsten erkennbar. Der Behälter 2 besitzt einen Boden 20 an dem die zylindrische Mantelwand 21 anschliesst, die über eine Schulter 22 in den Behälterhals 23 übergeht. Die Schulter 22 und der Behälterhals 23 sind hier besonders dickwandig realisiert, während die Mantelwand 21 und der Boden 20 dünner als die zuvor beschriebenen Bereiche gestaltet sind. Im hier dargestellten Beispiel ist der Behälter 2 eine längliche, dünne Flasche praktisch in Gestalt eines Stiftes. Das hier gezeigte Beispiel ist in etwa im Massstab 2 : 1 gezeichnet. In Realität entspricht somit der Behälter 2 in der Grosse etwa einem Füllfederhalter. Obwohl hier dieses bevorzugte Ausführungsbeispiel gezeigt ist, ist jedoch an sich die Gestalt des Behälters 2 nicht ausschlaggebend. Sicherlich ist für die Handhabung ein länglicher, zylindrischer Behälter vorteilhaft, doch kann dieser auch ohne weiteres eine zum Beispiel von der zylindrischen Form abweichende Gestalt haben, der Behälter kann auch kürzer oder bauchig oder im Querschnitt oval geformt sein. Gegebenenfalls muss jedoch der Hebel, der noch zu beschreibenden Dosiervorrichtung, der Behälterform angepasst sein, was jedoch dem Fachmann durchaus geläufig ist.In the figures, three different elements are visible. With 1 the actual metering device is drawn, while the container is designated 2 and the closure with 3. The container 2 can be seen most clearly in an axial longitudinal section in FIG. The container 2 has a bottom 20 on which the cylindrical jacket wall 21 connects, which merges via a shoulder 22 in the container neck 23. The shoulder 22 and the container neck 23 are realized here particularly thick-walled, while the shell wall 21 and the bottom 20 are designed thinner than the previously described areas. In the example shown here, the container 2 is an elongated, thin bottle practically in the form of a pen. This one example shown is drawn approximately on a 2: 1 scale. In reality, therefore, the container 2 in size corresponds approximately to a fountain pen. However, although this preferred embodiment is shown herein, the shape of the container 2 is not critical. Of course, an elongated, cylindrical container is advantageous for handling, but it may easily have a different form, for example, from the cylindrical shape, the container may also be shorter or bulbous or oval in cross-section. If necessary, however, the lever, the dosing device still to be described, must be adapted to the container shape, which however is familiar to the person skilled in the art.
Der Verschluss 3 ist selbstverständlich dem Zweck entsprechend angepasst, um eine möglichst geringe Mengenabgabe korrekt dosieren zu können. Entsprechend ist der Verschluss 3 in einer Abgabetülle mündend gestaltet. Da wiederum die Ausgestaltung des Verschlusses für die Erfindung nicht wesentlich ist, sondern lediglich für die Verwendung der Klebstoffabgäbe optimiert sein kann, wird daher hier nicht auf die exakte Ausgestaltung des Verschlusses 3 eingegangen.Of course, the closure 3 is adapted to the purpose in order to be able to dose the smallest possible quantity delivery correctly. Accordingly, the closure 3 is designed opening in a dispensing spout. Again, since the configuration of the closure for the invention is not essential, but can be optimized only for the use of Klebstoffabgäbe is therefore not discussed here on the exact configuration of the closure 3.
Die Dosiervorrichtung 1 besteht im Wesentlichen aus zwei Teilen, nämlich einerseits einem dem Behälter angepassten Ring 10 und einem mit dem Ring 10 verbundenen Hebel 11, der sich vom Ring 10 in Richtung zum Behälterhals 23 erstreckt und, wie in den Figuren 1 - 3 dargestellt, einstückig mit dem Ring 10 verbunden sein kann.The metering device 1 consists essentially of two parts, namely on the one hand a container adapted to the ring 10 and a ring 10 connected to the lever 11, the extends from the ring 10 in the direction of the container neck 23 and, as shown in Figures 1 - 3, may be integrally connected to the ring 10.
Der Ring 10 kann im Prinzip relativ dickwandig sein und auch eine von der runden Form abweichende Gestalt haben, falls der Boden des Behälters 2 eine von der runden Form abweichende Gestalt aufweist. Der Ring 10 muss jedoch so gestaltet sein, dass er auf den Behälter 2, insbesondere im Bereich von dessen Boden 20, auf den Behälter aufsteckbar ist. Weist somit der Behälter 2 einen ovalen Boden auf, so muss selbstverständlich auch der Ring 10 eine entsprechend ovale Gestalt aufweisen. Im hier dargestellten Beispiel ist jedoch der Behälter 2 kreiszylindrisch und entsprechend ist auch der Ring kreiszylindrisch.The ring 10 may in principle be relatively thick-walled and also have a different shape from the round shape, if the bottom of the container 2 has a different shape from the round shape. However, the ring 10 must be designed so that it can be plugged onto the container 2, in particular in the region of its bottom 20, onto the container. Thus, the container 2 has an oval bottom, so of course, the ring 10 must have a correspondingly oval shape. In the example shown here, however, the container 2 is circular cylindrical and, accordingly, the ring is circular cylindrical.
Da beim gewählten Ausführungsbeispiel der Behälter 2 praktisch die Form eines Stiftes hat und somit der Boden 20 nur eine relativ kleine Standfläche bilden würde, ist der Ring 10 hier doppelwandig gestaltet, wobei die innere Ringwand 12 direkt form- und kraftschlüssig im Bereich des Bodens den Behälter 2 umgreift. Eine äussere Ringwand 13, die zumindest im Bodenbereich distanziert um die innere Ringwand 12 läuft, ist konisch gestaltet, so dass im oberen Bereich die innere Ringwand 12 und die äussere Ringwand 13 zusammenfallen. Die äussere Ringwand 13 kannSince in the selected embodiment, the container 2 has practically the shape of a pin and thus the bottom 20 would form only a relatively small footprint, the ring 10 is designed double-walled here, the inner ring wall 12 directly form and locks in the region of the bottom of the container 2 surrounds. An outer ring wall 13, which extends at least in the bottom area distanced around the inner ring wall 12, is conical, so that in the upper region, the inner ring wall 12 and the outer ring wall 13 coincide. The outer ring wall 13 can
_ η _ selbstverständlich auch geschweift nach aussen verlaufend gestaltet sein._ η _ Of course also curly designed to run outward.
Im hier dargestellten Beispiel ist der Hebel 11 an der äusseren Ringwand 13 einstückig angeformt. Die äussere Ringwand 13 hat im Bereich von oben bis relativ nahe dem unteren Rand seitlich des Hebels 11 beidseitig seitliche Ausnehmungen 14. Dies erlaubt den Hebel 11 über eine gewisse Deformation der äusseren Ringwand 13 zu verschwenken. Diese Schwenkbarkeit wird erhöht indem direkt am Ring 13 eine Federplatte 15 angeformt ist, die direkt in den Hebel 11 übergeht. Die Federplatte 15 verläuft von der Anbindungsstelle 16 in etwa parallel zu einer Tangentialebene der Mantelwand bis zu einer ersten Knickstelle 17. Im Bereich der Knickstelle sind 3 überhöhte Versteifungsrippen 18 vorgesehen. Die beiden äusseren Versteifungsrippen 18 verlaufen dabei fluchtend mit der umlaufenden Seitenwand 19 des Hebels 11. Die Seitenwand 19 verläuft über die gesamte Länge des Hebels 11 an dessen Seiten und vordere Stirnseiten entlang. Der Hebel 11 ist somit mit einer zum Behälter 2 hin gerichteten umlaufenden Wand versehen, die zur Versteifung des Hebels dient. Die Versteifung des Hebels ist somit, mit Ausnahme im Bereich der Federplatte, überall vorhanden so dass der Hebel 11 an sich biegesteif ist, mit Ausnahme des Bereiches welcher zur Federplatte 15 gehört. Der Hebel 11 ist zudem mit einem Drückerfortsatz 110 versehen, der auf der Mantelwand 21 des Behälters 2 aufliegt.In the example shown here, the lever 11 is integrally formed on the outer annular wall 13. The outer ring wall 13 has in the region from above to relatively close to the lower edge of the side of the lever 11 on both sides lateral recesses 14. This allows the lever 11 to pivot over a certain deformation of the outer ring wall 13. This pivoting is increased by directly on the ring 13, a spring plate 15 is formed, which merges directly into the lever 11. The spring plate 15 extends from the connection point 16 approximately parallel to a tangential plane of the jacket wall up to a first kink 17. In the region of the kink, 3 elevated stiffening ribs 18 are provided. The two outer stiffening ribs 18 extend in alignment with the circumferential side wall 19 of the lever 11. The side wall 19 extends over the entire length of the lever 11 on its sides and front end sides along. The lever 11 is thus provided with a directed towards the container 2 circumferential wall, which serves to stiffen the lever. The stiffening of the lever is thus, with the exception of the spring plate, everywhere present so that the lever 11 is rigid in itself, with the exception of the area which belongs to the spring plate 15. The lever 11 is also provided with a handle extension 110 which rests on the jacket wall 21 of the container 2.
Der Drückerfortsatz 110 kann im Prinzip an einer beliebigen Stelle am Hebel 11 angebracht sein, doch wird man diesen bevorzugterweise etwa in der Mitte zwischen derThe pusher extension 110 may, in principle, be mounted anywhere on the lever 11, but this is preferably located approximately midway between the
Anbindungsstelle 16 und dem Hebelende 111 anordnen. Je näher der Drückerfortsatz 110 zum Hebelende 111 verlegt wird, um so höher ist die aufzuwendende Kraft, und je näher der Drückerfortsatz beim Ring 10 zu liegen kommt, um so geringer ist die erforderliche Kraft, mit der der Drückerfortsatz 110 auf die Mantelwand 21 gedrückt werden muss um dabei dieArrange connection point 16 and the lever end 111. The closer the pusher extension 110 is moved to the lever end 111, the higher the force to be applied, and the closer the pusher extension to the ring 10 comes to rest, the lower the force required to press the pusher extension 110 onto the jacket wall 21 must order the
Mantelwand zu verformen, wobei allerdings auch dieMantle wall to deform, although also the
Eindrücktiefe kleiner wird je näher der Drückerfortsatz 110 beim Ring 10 zu liegen kommt. Entsprechend wird man denThe depth of depression becomes smaller the closer the pusher extension 110 comes to rest at the ring 10. Accordingly one becomes the
Drückerfortsatz etwa in der Mitte vom unteren Rand des RingesPressing process approximately in the middle of the lower edge of the ring
10 bis zum Hebelende 111 anbringen.10 attach to the end of the lever 111.
Der Drückerfortsatz 110 ist beim hier dargestellten Beispiel an einer mittleren Versteifungsrippe 112 angeformt, welche mittig zwischen den umlaufenden Mantelwänden 19 auf derIn the example shown here, the presser extension 110 is formed on a middle reinforcing rib 112, which is located centrally between the circumferential casing walls 19 on the
Hebelunterseite angeformt ist. Während die überhöhtenLever bottom is molded. While the inflated
Versteifungsrippen 18 von der Mantelwand des Behälters wegweisen, verläuft zumindest die eine mittlere Versteifungsrippe 112 auf der Unterseite des Hebels und ist auf den Behälter 2 hin gerichtet. In der Figur 3 erkennt man zudem, dass der Behälter 2 im bodennahen Bereich mit einer Einformung 24 versehen ist, die hier die Form einer umlaufenden Einschnürung hat. In diese Einformung 24 greifen Federzungen 113 ein, die ein Abziehen der Dosiervorrichtung 1 vom Behälter 2 verunmöglicht .Point stiffening ribs 18 away from the shell wall of the container, at least runs a central stiffening rib 112 on the underside of the lever and is directed to the container 2 out. In addition, it can be seen in FIG. 3 that the container 2 is provided with an indentation 24 in the region near the bottom, which here has the shape of a circumferential constriction. In this indentation 24 spring tongues 113 engage, which makes it impossible to remove the metering device 1 from the container 2.
Sämtliche Versteifungsrippen 18 und 112 verlaufen in Ebenen, die parallel zur Längsachse des Behälters verlaufen. Die Versteifungsrippen können im Prinzip beliebig lang sein, doch sollten sie sich vorteilhafterweise nicht über die Mitte der Federplatte 15 hinweg erstrecken, so dass die Federplatte 15 nicht auch noch vollständig versteift ist, sondern einen Bereich aufweist, der der gewollten Verformung zu dienen vermag. Dieser deformierbare Bereich bildet eigentlich ein scharnierfreies Gelenk.All stiffening ribs 18 and 112 extend in planes that are parallel to the longitudinal axis of the container. The stiffening ribs can be arbitrarily long in principle, but they should advantageously not extend beyond the center of the spring plate 15 away, so that the spring plate 15 is not completely stiffened, but has a range which is able to serve the intended deformation. This deformable area actually forms a hinge-free joint.
Die erfindungsgemässe Dosiervorrichtung 1 lässt sich extrem preiswert realisieren und kann somit als Einwegelement gestaltet sein, das direkt ab Werk auf den Behälter aufgesetzt geliefert wird. Dabei ist es selbstverständlich durchaus erwünscht, dass diese Einwegdosiervorrichtung nicht für andere Zwecke missbraucht wird. Neben der irreversiblen Verbindung über die Formschlussmittel 113 kann zudem die Mantelwand 21 des Behälters 2 mit einer Ringwulst 25 versehen sein, die ein Abstreifen der Dosiervorrichtung in Richtung zum Behälterhals verunmöglicht. Da die Behälter 2 meist aus Kunststoff geblasen werden und diese geblasenen Behälter gewisse Toleranzen bezüglich dem Durchmesser aufweisen, kann es sinnvoll sein, den Ring 10 und insbesondere falls der Ring 10 doppelwandig gestaltet ist, die innere Ringwand 12 mit in regelmässigen Abständen angeordneten Ausbuchtungen 124 zu versehen, die eine gewisse elastische Verformung des Ringes zulassen und gleichzeitig Raum für die verformte Mantelwand 21 im bodennahen Bereich 20 bildet. Sind solche Ausbuchtungen 124 vorgesehen, so wird man vorzugsweise auch die Formschlussmittel 113, die üblicherweise als Federzungen gestaltet sind, in diesen Ausbuchtungen 124 anordnen. The metering device 1 according to the invention can be realized extremely inexpensively and can thus be designed as a disposable element which is delivered directly from the factory to the container. It is of course quite desirable that this disposable dosing device is not abused for other purposes. In addition to the irreversible connection via the interlocking means 113, furthermore, the jacket wall 21 of the container 2 can be provided with an annular bead 25 which makes it impossible to remove the metering device in the direction of the container neck. Since the containers 2 are usually blown from plastic and these blown containers have certain tolerances with respect to the diameter, it may be useful to the ring 10 and in particular if the ring 10 is double-walled, the inner annular wall 12 with arranged at regular intervals bulges 124 to provided that allow a certain elastic deformation of the ring and at the same time makes room for the deformed shell wall 21 in the ground-near region 20. If such bulges 124 are provided, it is also preferable to arrange the interlocking means 113, which are usually designed as spring tongues, in these bulges 124.
