Definitions
- the present invention relates to a two-piece plastic dosing for solid or flexible containers, in particular for use on plastic film bag, consisting of a fastened to the container base and a screw-on held closing part, said by the screwing movement, the two parts relative to each other in the axial direction displaceable and can be brought from a closed position in an open position and vice versa, wherein the base part has an external thread and disposed above at least one outlet opening, while the closing part has an internal thread and a central outlet opening, and wherein the base part with a cylindrical portion with external thread and a head part with a frusto-conical outer contour is present above this, and that the head part has a conical jacket wall which has at least one outlet opening and is closed with a cover surface of the head part n is while the closing part above it in a cylindrical section attached internal thread is designed as a counterparts truncated cone.
- the closing part contributes a functional proportion to the metered delivery, shows the GB 1399840 a solution which is much more complex and is provided with an actual valve plate, in which case the closing part does not play any part in the metering action of the closure.
- a closing and dosing function has the closing part in the form of a screw cap like this GB-1187081-A shows. In this case, an opening is present eccentrically in the top surface and this opening is closed by the container neck or a base part which engages in the closed position in this opening.
- This solution is extremely simple in construction, but is only suitable as a metering closure for dispensing small quantities. Typically, such dosing caps have been mounted on containers for cosmetics.
- DE-A-2839284 considered. It is a two-piece plastic dosing for solid and flexible container, consisting of a fastened to the container base and a schraubbeweglich held closing part, wherein the screwing movement, the two parts relative to each other in the axial direction and displaceable from a closed position in an open position and vice versa are brought.
- the base part has an external thread and arranged above at least one outlet opening
- the closing part has an internal thread and a central outlet opening
- the base part with a cylindrical portion with External thread and above a part with frustoconical outer contour is present.
- two-part metering closures of the above type are known in a similar construction for a long time.
- An example of these older closures shows a tube closure according to the DE 636805 A .
- Closures constructed on the same principle, namely with a lower frusto-conical part and a conical part displaceable relative thereto, have been known for a long time, but these are conceived as tube closures and the base part is practically designed as a full body.
- the proven closest prior art has a lower part, which is practically made of a solid body and the openings are practically designed as channels.
- a tube closure is known, but here, instead of a truncated cone, two conical parts are aligned. This of course allows only a small outlet opening and this must be centrally located above the top of the lower cone, while in the lower part, the openings are formed in the cone wall.
- the present invention two-part dosing closure is designed and designed for containers with large volumes and corresponding larger amounts to be dosed. Accordingly, significantly larger outlet openings are thus closed.
- the cost of materials is much too large.
- a corresponding thin-walled solution of both the lower part As well as the upper part to thus save material would be obvious to the skilled person, but this can not be realized because of the forces occurring in an obvious way, since a one to one implementation of the previous solutions would lead to leakage problems resulting from the Thinness would result.
- the base part should have the shape of a above the external thread over a cylindrical portion arranged with the male thread head portion, wherein in the conical jacket wall at least one outlet opening is mounted and the top surface of the head portion is closed, while the closing part is designed above its mounted in a cylindrical portion internal thread, as opposed truncated cone, the top surface of the truncated cone is at least approximately completely open and in the closed state, the conical outer surface of the shell wall of the base part and the conical inner surface of the Closing parts sealingly come to rest on each other and is characterized by the features of claim 1.
- the dosing closure which is generally designated 1, and as such in FIG. 2 it can be seen, consists of the two main components, namely the base part 2 and the closing part 3.
- the base part 2 is used for direct attachment to a container, in the example enclosed here for attachment to a foil bag.
- the base part 2 has a circumferential, outwardly directed flange 26, which adjoins terminally on a cylindrical portion 22.
- This cylindrical portion 22 has an external thread 20.
- a part which is referred to collectively as the head part 23.
- This head part 23 has a conical jacket wall 24.
- a cover surface 25 closes the head part 23 upwards. The top surface 25 is thus completely closed.
- At least one outlet opening 21 is formed.
- a plurality of outlet openings 21 are present.
- the outlet openings can here be practically so large that only narrow webs remain between the individual outlet openings 21.
- three outlet openings 21 are formed, which make up a total of approximately 50% of the surface of the conical jacket wall 24.
- the outlet openings 21 in height designed so that they extend at least approximately over the entire height of the conical jacket wall 24. This embodiment is particularly suitable for liquid media in which a large volume should be dispensed each.
- the outlet openings will be so large that virtually only narrow webs remain between the individual outlet openings 21, so that virtually no material on the outside surface of the closure will be present when closing the closure now on a few webs reduced conical jacket wall 24 may remain.
- the completely closed cover surface 25 adjoins.
- the top surface is preferably designed in the material thickness so that the wall thickness of the top surface 25 is practically twice as thick as the conical jacket wall 24 of the head part 23.
- a circumferential shoulder is formed in the edge region, which forms a ledge 28.
- the height of this ledge 28 corresponds approximately to the thickness of the conical jacket wall 24 of the head part 23.
- In the vertical region of the ledge 28 also has a circumferential sealing groove 29 is formed, as most likely in the FIG. 4 is recognizable.
- On the base part 2 of the already mentioned closing part can be screwed.
- the closing part 3 is designed so that its inner surface in the closed state comes to lie sealingly on the outer surface of the base part.
- the closing part 3 also has a cylindrical portion 31.
- the internal thread 30 of the closing part 3 is formed. This internal thread is only in the sectional drawings of FIGS. 3 and 4 recognizable.
- the cylindrical portion 31 of the closing part 3 also includes a truncated cone 33 at.
- the jacket wall 34 of the truncated cone 33 is completely closed.
- the top surface 32 of the truncated cone 33 is completely open except for an upper edge 35 and forms the outlet opening 32 'of the closing part 3.
- the cylindrical portion 31 has on its outside means 42 for increasing the grip. These means may be designed, for example, vertically extending ribs or as darg Congress here, like a polygonal nut polygonal.
- FIG. 2 shows a preferred embodiment of the various seals for a liquid media metering closure.
- the seal is characterized in that the truncated cone 23 of the base part 2 engages positively in the outlet opening 32 'of the top surface 32 of the closing part 3.
- the base part as already described, a circumferential ledge 28 and the jacket wall 34 of the truncated cone 33 of the closing part is designed so that the jacket wall 34 is bent inwardly terminal and thus forms the aforementioned crank 36.
- This crank 36 comes to lie positively in and on the ledge 28, which bounds from the top surface 25 marginally inwardly projecting this top surface 25.
- the bend 36 at the vertical end with a sealing bead 37, which is directed towards the center, provided.
- This sealing bead is practically a short inward lip with a thickness of a few tenths of a millimeter. It makes sense to bring into the vertical portion of the ledge 28 a form-fitting to the sealing bead 37 matching sealing groove 29 at. In the fully closed state thus engages the sealing bead 37 in the corresponding sealing groove 29 a.
- sealing beads 38 are formed, which project perpendicularly from this conical jacket wall 34, and their course of the shape of the outlet openings 21 are adapted. These sealing beads 38 are in the fully closed state of the metering at the edges of the outlet openings 21 sealingly. This results in a tactile snapping in the closed position, since these sealing beads 38 already rest on the outer surface of the conical jacket wall 24 before reaching the end position and thereby practically clean this conical jacket wall. The user hears and therefore feels when he closes the dosing completely and just as he has to overcome an increased resistance before he can open the dosing.
- retaining collar 27 formed at the base part 2 a retaining collar 27 formed at the base part 2 .
- This retaining collar 27 extends below the external thread 20 of the base part 2, so practically in the region between the flange 26 and the external thread 20 on the cylindrical portion 22.
- retaining hooks 39 are formed at the closing part 3 , which at the maximum screwing of the closing part 3 on the retaining collar 27 for Stop come.
- These retaining hooks 39 may be formed directly on extensions or on the lower edge of the cylindrical portion 31. In the illustrated here, particularly preferred embodiment, the retaining hooks 39 are integrally formed on spring tongues 41.
- spring tongues 41 are formed in recesses 40 in the jacket wall of the cylindrical portion of the closing part 3. This embodiment has two advantages, namely on the one hand is facilitated by a mounting and secondly carried by the retaining hook 39, during assembly, no violation of the thread, which therefore also retains its sealing effect.
- the spring tongues 41 are designed to be longer than the height of the cylindrical portion 31 and therefore protrude downwards. This is for example in the FIG. 2 but also in the FIGS. 3 and 4 , recognizable. In the FIG. 1 are such spring tongues 41 can not be seen, since here the retaining hook 39 is designed as a circumferential bead on the inside of the cylindrical portion 31 of the closing part 3.

Description
Die vorliegende Erfindung betrifft einen zweiteiligen Dosierverschluss aus Kunststoff für feste oder flexible Behälter, insbesondere für die Verwendung auf Kunststofffolienbeutel, bestehend aus einem auf das Behältnis befestigbaren Basisteil und einem darauf schraubbeweglich gehaltenen Schliessteil, wobei durch die Schraubbewegung die beiden Teile relativ zu einander in achsialer Richtung verschiebbar und von einer geschlossenen Position in einer offenen Position und umgekehrt bringbar sind, wobei der Basisteil ein Aussengewinde und darüber angeordnete mindestens eine Austrittsöffnung aufweist, während der Schliessteil ein Innengewinde und eine zentrale Austrittsöffnung aufweist, und wobei der Basisteil mit einem zylindrischen Bereich mit Aussengewinde und darüber ein Kopfteil mit kegelstumpfförmigen Aussenkontur vorhanden ist, und dass der Kopfteil eine konische Mantelwand hat, die mindestens eine Austrittsöffnung aufweist und mit einer Deckfläche des Kopfteiles geschlossen ist, während der Schliessteil oberhalb seines in einem zylindrischen Abschnitt angebrachten Innengewinde als gegengleichen Kegelstumpf gestaltet ist.The present invention relates to a two-piece plastic dosing for solid or flexible containers, in particular for use on plastic film bag, consisting of a fastened to the container base and a screw-on held closing part, said by the screwing movement, the two parts relative to each other in the axial direction displaceable and can be brought from a closed position in an open position and vice versa, wherein the base part has an external thread and disposed above at least one outlet opening, while the closing part has an internal thread and a central outlet opening, and wherein the base part with a cylindrical portion with external thread and a head part with a frusto-conical outer contour is present above this, and that the head part has a conical jacket wall which has at least one outlet opening and is closed with a cover surface of the head part n is while the closing part above it in a cylindrical section attached internal thread is designed as a counterparts truncated cone.
Dosierverschlüsse aus Kunststoff mit dem hier interessierenden Aufbau sind bereits seit den 50 Jahren bekannt. Ein typisches Beispiel zeigt die
Während bei der vorgenannten Lösung der Schliessteil einen funktionalen Anteil zur dosierten Abgabe beiträgt, zeigt die
Die Mehrheit der hier interessierenden Lösungen besitzen üblicherweise einen Schliessteil mit einer oberen, in der Deckfläche angebrachten zentralen Öffnung und einen Dichtstift der mittelbar oder direkt mit einem Basisteil verbunden ist, wobei diese beiden Teile relativ zueinander durch eine Schraubbewegung auf und ab bewegt werden können, so dass die Flüssigkeit um den Dichtstift herum zur Austrittsöffnung strömen kann. Ein typisches Beispiel einer solchen Lösung zeigt die
Als nächstliegenden Stand der Technik wird die
Prinzipiell sind zweiteilige Dosierverschlüsse der obgenannten Art in ähnlicher Bauweise seit längerem bekannt. Ein Beispiel dieser älteren Verschlüsse zeigt ein Tubenverschluss gemäss der
Der hier vorliegende, erfindungsgemässe zweiteilige Dosierverschluss ist jedoch für Behälter mit grossen Volumen und entsprechenden grösseren zu dosierenden Mengen ausgelegt und gestaltet. Entsprechend werden damit auch wesentlich grössere Austrittsöffnungen verschlossen. Bei solchen Systemen lassen sich Unterteile, die praktisch aus einem vollen Körper gestaltet sind, ökologisch und ökonomisch nicht mehr vertreten. Der Materialaufwand ist dabei viel zu gross. Eine entsprechende dünnwandige Lösung sowohl des Unterteiles als auch des Oberteiles um somit Material zu sparen wäre an sich für den Fachmann naheliegend, doch lässt sich dies wegen den dabei auftretenden Kräften nicht in naheliegender Weise realisieren, da eine eins zu eins Umsetzung der bisherigen Lösungen zu Dichtigkeitsproblemen führen würden, die sich aus der Dünnwandigkeit ergeben würden.However, the present invention, two-part dosing closure is designed and designed for containers with large volumes and corresponding larger amounts to be dosed. Accordingly, significantly larger outlet openings are thus closed. In such systems, parts that are practically designed from a full body, ecologically and economically no longer represented. The cost of materials is much too large. A corresponding thin-walled solution of both the lower part As well as the upper part to thus save material would be obvious to the skilled person, but this can not be realized because of the forces occurring in an obvious way, since a one to one implementation of the previous solutions would lead to leakage problems resulting from the Thinness would result.
Es ist daher die Aufgabe der vorliegenden Erfindung einen zweiteiligen Dosierverschluss der eingangs genannten Art derart zu verbessern, dass auch ein grosser Dosierverschluss dünnwandig und somit materialsparend fertigbar ist, der auch entsprechend höherem Innendruck stand zu halten vermag.It is therefore an object of the present invention to improve a two-part metering closure of the type mentioned in such a way that even a large metering is thin-walled and thus material-saving manufacturable, which is able to withstand correspondingly higher internal pressure.
Diese Aufgabe löst ein zweiteiliger Dosierverschluss aus Kunststoff der eingangs genannten Art mit den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1. Hierbei soll der Basisteil die Form eines oberhalb des Aussengewindes über einen zylindrischen Bereich mit dem Aussengewinde angeordneten Kopfteil aufweisen, wobei in der konischen Mantelwand, die mindestens eine Austrittsöffnung angebracht ist und die Deckfläche des Kopfteiles geschlossen ist, während der Schliessteil oberhalb seines in einem zylindrischen Abschnitt angebrachten Innengewinde, als gegengleichen Kegelstumpf gestaltet ist, wobei die Deckfläche des Kegelstumpfes mindestens annähernd vollständig offen ist und im geschlossenen Zustand die konische Aussenfläche der Mantelwand des Basisteiles und die konische Innenfläche des Schliessteiles dichtend aufeinander zu liegen kommen und sich auszeichnet durch die Merkmale des Patentanspruches 1.This object is achieved by a two-piece plastic dosing of the type mentioned above with the features of the characterizing part of

In der
In der konischen Mantelwand 24 ist mindestens eine Austrittsöffnung 21 eingeformt. Bevorzugterweise sind jedoch mehrere Austrittsöffnungen 21 vorhanden. Die Austrittsöffnungen können hier praktisch so gross sein, dass zwischen den einzelnen Austrittsöffnungen 21 lediglich noch schmale Stege bestehen bleiben. Im hier dargestellten, bevorzugten Ausführungsbeispiel sind drei Austrittsöffnungen 21 eingeformt, die gesamthaft rund 50% der Oberfläche der konischen Mantelwand 24 ausmachen. Ebenfalls bevorzugt werden die Austrittsöffnungen 21 in der Höhe so gestaltet, dass diese sich mindestens annähernd über die gesamte Höhe der konischen Mantelwand 24 erstrecken. Diese Ausgestaltungsform ist insbesondere für flüssige Medien geeignet, bei denen ein grosses Volumen jeweils abgegeben werden soll. Handelt es sich beim Inhalt eher um rieselförmige Produkte, wie beispielsweise Salz, so wird man bevorzugterweise die Austrittsöffnungen so gross gestalten, dass praktisch nur noch schmale Stege zwischen den einzelnen Austrittsöffnungen 21 verbleiben, so dass beim Schliessen des Verschlusses praktisch kein Material auf der Aussenfläche der nun auf wenige Stege reduzierte konische Mantelwand 24 verbleiben kann.In the
Oberhalb der konischen Mantelwand 24 schliesst, wie bereits erwähnt, die vollständig geschlossene Deckfläche 25 an. Die Deckfläche wird bevorzugterweise in der Materialstärke so gestaltet, dass die Wandstärke der Deckfläche 25 praktisch doppelt so dick ist wie die konische Mantelwand 24 des Kopfteiles 23. In dieser Deckfläche 25 ist im Randbereich ein umlaufender Absatz eingeformt, der einen Sims 28 bildet. Die Höhe dieses Sims 28 entspricht in etwa der Dicke der konischen Mantelwand 24 des Kopfteiles 23. Im vertikalen Bereich des Sims 28 ist zudem eine umlaufende Dichtrille 29 eingeformt, wie dies am ehesten in der
Je nach dem wie hoch der zylindrische Bereich 22 bzw. der zylindrische Abschnitt 31 des Schliessteiles gestaltet sind, um so grösser ist die relative, axiale Bewegungsfreiheit des Schliessteiles relativ zum Basisteil 2, und entsprechend ist der verbleibende Freiraum zwischen dem Kegelstumpf 23 des Basisteiles 2 und dem Kegelstumpf 33 des Schliessteiles 3 entsprechend gross. Für die Verwendung von rieselfähigen Produkten dürfte entsprechend dieser zylindrische Teil 22 bzw. der zylindrische Abschnitt 31 eher länger gestaltet sein als bei einem entsprechenden Dosierverschluss für flüssige Medien.Depending on how high the
Entsprechend ist selbstverständlich auch die Anforderung der Dichtigkeit eines solchen Verschlusses bei der Verwendung für fliessfähig Medien entsprechend höher als bei der Verwendung auf Behältnissen in denen rieselfähige Medien enthalten sind. In den
Als weitere Dichtung ist hier vorgesehen, dass auf der Innenseite der konischen Mantelwand 34 Dichtwülste 38 angeformt sind, die senkrecht von dieser konischen Mantelwand 34 abstehen, und deren Verlauf der Form der Austrittsöffnungen 21 angepasst sind. Diese Dichtwülste 38 liegen im vollständig geschlossenen Zustand des Dosierverschlusses an den Kanten der Austrittsöffnungen 21 dichtend an. Hierdurch entsteht ein fühlbares Einrasten in der Schliessstellung, da diese Dichtwülste 38 bereits auf die Aussenfläche der konischen Mantelwand 24 vor dem Erreichen der Endposition aufliegen und dabei praktisch diese konische Mantelwand reinigen. Der Benützer hört und fühlt somit wenn er den Dosierverschluss vollständig schliesst und genau so muss er einen erhöhten Widerstand überwinden, bevor er den Dosierverschluss öffnen kann.As a further seal is provided here that on the inside of the
Selbstverständlich und insbesondere für die dosierte Abgabe von flüssigen Medien ist es sinnvoll, wenn der Öffnungsbereich begrenzt ist und der Benützer nicht irrtümlich den Schliessteil vollständig vom Basisteil abschrauben kann. Um dies zu verhindern, ist am Basisteil 2 ein Rückhaltkragen 27 angeformt. Dieser Rückhaltekragen 27 verläuft unterhalb des Aussengewindes 20 des Basisteiles 2, also praktisch im Bereich zwischen dem Flansch 26 und dem Aussengewinde 20 am zylindrischen Bereich 22. Am Schliessteil 3 sind entsprechend Rückhaltehaken 39 angeformt, die bei der maximalen Aufschraubung des Schliessteiles 3 am Rückhaltkragen 27 zum Anschlag kommen. Diese Rückhaltehaken 39 können direkt an Verlängerungen oder am unteren Rand des zylindrischen Abschnittes 31 angeformt sein. In der hier dargestellten, besonderes bevorzugten Ausführungsform, sind die Rückhaltehaken 39 an Federzungen 41 angeformt. Diese Federzungen 41 sind in Nischen 40 in der Mantelwand des zylindrischen Abschnittes des Schliessteiles 3 eingeformt. Diese Ausgestaltungsform hat zwei Vorteile, nämlich zum einen wird hier durch eine Montage erleichtert und zum zweiten erfolgt durch den Rückhaltehaken 39, während der Montage, keine Verletzung des Gewindes, welches daher ebenfalls seine Dichtwirkung behält. Die Federzungen 41 sind länger gestaltet als die Höhe des zylindrischen Abschnittes 31 und ragen daher nach unten vor. Dies ist beispielsweise in der
