Description

Die Erfindung betrifft eine Mehrkomponenten-Packung gemäß Gattungsbegriff des Anspruches 1.The invention relates to a multi-component pack according to the preamble of claim 1.

Eine derartige Mehrkomponenten-Packung ist aus der EP-A-133 293 her bekannt. Die dort vorgeschlagene Zweikomponenten-Packung sieht einen Einsatzbecher vor, der in die Halsöffnung eines Außenbehälters einsteckbar ist, so daß zwei Komponenten jeweils vom Außenbehälter und vom Einsatzbecher getrennt aufbewahrt werden können. Durch Aufschrauben der Schraubkappe über die Verkaufsgrundstellung hinaus wird die Ringstufe des Becherbodens von einer Stoßkante beaufschlagt, so daß die Sollbruchlinie zertrennt wird und der Einsatzbecher in den Außenbehälter hineinfällt, so daß beide Komponenten zusammengeführt werden. Ein solcher Becher ist jedoch verbesserungswürdig, da er lediglich zwei Komponenten getrennt voneinander aufnehmen kann.Such a multi-component pack is known from EP-A-133 293. The two-component pack proposed there provides an insert cup which can be inserted into the neck opening of an outer container, so that two components can be stored separately from the outer container and from the insert cup. By unscrewing the screw cap beyond the basic sales position, the ring step of the cup base is acted upon by a butt edge, so that the breaking line is separated and the insert cup falls into the outer container, so that both components are brought together. However, such a cup is in need of improvement since it can only accommodate two components separately from one another.

Aus der DE-U-8 423 225 ist es bekannt, einen in die Halsöffnung eines Außenbehälters eingehängten, ein Konzentrat enthaltenden Becher mittels einer Stoßkante einer Schraubkappe so zum Innenraum des Außenbehälters hin zu öffnen, daß eine am Boden dieses Bechers liegende Sollbruchlinie nur so weit reißt, daß eine Materialverbindung zwischen Becherwand und Becherboden verbleibt, der Boden also nur klappdeckelartig abklappt.From DE-U-8 423 225 it is known to open a cup which is suspended in the neck opening of an outer container and contains a concentrate by means of a butt edge of a screw cap to the interior of the outer container in such a way that a predetermined breaking line lying on the bottom of this cup is only so far tears that a material connection remains between the cup wall and the cup bottom, so the bottom only folds down like a hinged lid.

Der Erfindung liegt daher die Aufgabe zugrunde, eine gattungsgemäße Mehrkomponenten-Packung bei einfacher Bauform hinsichtlich ihrer Einsatzmöglichkeit zu verbessern.The invention is therefore based on the object of improving a generic multi-component pack with a simple design with regard to its possible use.

Gelöst wird die Aufgabe durch die im Anspruch 1 beschriebene Erfindung.The object is achieved by the invention described in claim 1.

Die angefügten Ansprüche stellen vorteilhafte Weiterbildungen dar.The appended claims represent advantageous developments.

Zufolge derartiger Ausgestaltung ist eine Mehrkomponenten-Packung gegeben mit mehreren ineinander gesteckten Einsatzbechern. Ein erster Einsatzbecher ist fest in die Halsöffnung des Außenbehälters eingesteckt. Ein oder mehrere zweite Einsatzbecher sind in den ersten Einsatzbecher eingesteckt. Durch weiteres Aufschrauben der Schraubkappe über die Verkaufsgrundstellung hinweg wird die Sollbruchlinie eines jeden Einsatzbechers aufgetrennt. Hierzu ist vorgesehen, daß die Ringstufen von der Stoßkante eines Stoßkragens beaufschlagt werden.As a result of such an embodiment, a multi-component pack is provided with a plurality of insert cups inserted one into the other. A first insert cup is firmly inserted into the neck opening of the outer container. One or more second insert cups are inserted in the first insert cup. By further screwing on the screw cap beyond the basic sales position, the predetermined breaking line of each insert cup is separated. For this purpose it is provided that the ring steps are acted upon by the abutting edge of a abutting collar.

Konkret wird dazu so vorgegangen, daß mindestens ein weiterer, im ersten Einsatzbecher zentrierter Einsatzbecher zugeordnet ist, dessen sich in axialer Richtung über seinen Becherboden hinaus fortsetzende Becherwand einen eigenen Stoßkragen ausbildet, der Becherboden des weiteren, im ersten Einsatzbecher zentrierten Einsatzbechers im Bereich einer Sollbruchstelle eine Ringstufe aufweist, diese Ringstufe von einer mit dieser Ringstufe fluchtenden Stoßkante eines in diesen Einsatzbecher ragenden Stoßkragens beaufschlagbar ist, eine Dichtung zwischen Mantelfläche des Stoßkragens und der weiteren Becherwand gegeben ist, der Stoßkragen der Schraubkappe angeformt ist und der weitere Einsatzbecher axial verlagerbar ist. In vorteilhafter Weise ist den zweiten Einsatzbechern ein Antriebsnocken an der äußeren Becherwand angeformt, der einer Antriebskante und einer Anschlagkante zwischengeordnet und von diesen beaufschlagbar ist. Ist nur ein zweiter Einsatzbecher vorgesehen, so wird die Anschlagkante von einem die Halsöffnung des Außenbehälters umfangenden Rand des ersten Einsatzbechers ausgebildet. Die Antriebskante wird dann von der Stirnfläche eines der Schraubkappe zugeordneten Antriebskragens ausgebildet. Sind mehrere ineinandergesteckte zweite Einsatzbecher vorgesehen zur Aufnahme von mehr als nur drei Komponenten, so beaufschlagt der Antriebsnocken jedes zweiten Einsatzbechers bei weiterem Aufschrauben der Schraubkappe die von der Oberkante des ihn aufnehmenden Einsatzbechers gebildete Anschlagkante. Handelt es sich bei diesem ebenfalls um einen zweiten Einsatzbecher, so wird dieser durch die Beaufschlagung der Oberkante axial verlagert. Der Antriebsnocken ist derart angeordnet, daß nach dem Auftrennen der Sollbruchlinie des innersten zweiten Einsatzbechers der Antriebsnocken durch weiteres Aufschrauben der Schraubkappe von der Antriebskante der Schraubkappe beaufschlagt wird. Nach dem Auftrennen der Sollbruchlinie des ersten Einsatzbechers wird dessen Anschlagkante durch weiteres Aufschrauben der Schraubkappe vom Antriebsnocken des in ihn eingesteckten zweiten Einsatzbechers beaufschlagt. Vorteilhafterweise ist der Antriebsnocken so ausgebildet, daß er den zweiten Einsatzbecher ringförmig umgibt. Zur Erzielung eines optimalen Auftrennens der Sollbruchlinie ist vorgesehen, daß die von der Stoßkante und der Ringstufe ausgebildeten Querschnittflächen sich senkrecht zur Drehachse der Schraubkappe erstrecken. Weiterhin vorgesehen ist ein Abstand zwischen der Stoßkante und der Ringstufe bei nicht aufgeschraubter Schraubkappe. Um auch bei nicht aufgeschraubter Schraubkappe einen sicheren Halt der Schraubkappe auf dem Außenbehälter zu gewährleisten, ist an der Halsöffnung des Außenbehälters eine umlaufende Rastkante vorgesehen, über die die Schraubkappe mit einem Ringwulst aufgeklipst ist. Durch diese und andere Reibungsflächen der Schraubkappe mit Außenbehälter und Einsatzbechern ist eine Schwergängigkeit des Aufschraubens erzielt. Ein Aufschrauben und eine damit verbundene Auftrennung der Sollbruchlinien zum Zusammenführen der Komponenten ist damit nur durch ein gewolltes Drehen der Schraubkappe möglich. Vorteilhafterweise weist die Verschlußkappe eine Öffnung auf, die mit einer Verschlußkappe verschließbar ist. Hierdurch braucht zu einer Entnahme der Komponentenmischung die Schraubkappe nicht entfernt zu werden, die Entnahme erfolgt vielmehr durch sämtliche Einsatzbecher hindurch durch die Öffnung der Schraubkappe. Um eine Vermischung vor dem Zertrennen der Sollbruchlinien der einzelnen Komponenten untereinander zu verhindern, ist zwischen der Becherwand und dem darin einsteckenden Stoßkragen ein dichtender Wulst eingeordnet. Dieser der Becherwand angeformte Wulst umgibt den Stoßkragen spannend, er liegt also eng an, so daß ein radialer Anpreßdruck herrscht. Zur sicheren parallelen Führung der axial verschieblichen zweiten Einsatzbecher sind zwei parallel angeordnete, sich auf jeder Becherinnenseite befindende Wülste vorgesehen. Hierdurch ist zusätzlich noch eine doppelte Abdichtung realisiert. Der Becherboden kann topfförmig ausgestaltet sein. Dies ermöglicht eine einfacherer Fertigung. Um ein Abscheren der Stege beim weiteren Aufschrauben der Schutzkappe zu verhindern und ein wirkungsvolles Abklappen der Becherböden nach der Auftrennung der Sollbruchlinien zu gewährleisten ist vorgesehen, daß die Stege, die den Becherboden mit der Becherwand verbinden, bei aufgetrennter Sollbruchlinie eine Auflauframpe für die Stoßkanten des Stoßkragens ausbilden. Ein Loslösen eines Becherbodens vom Einsatzbecher wird in einfacher und sicherer Weise verhindert durch einen den Becherboden mit der Becherwand verbindenden Steg, der bei aufgetrennter Sollbruchlinie eine Materialverbindung zwischen Becherwand und Becherboden ausbildet.Specifically, the procedure is such that at least one further insert cup centered in the first insert cup is assigned, the cup wall of which extends in the axial direction beyond its cup base and has its own bump collar, the cup base of the further insert cup centered in the first insert cup in the area of a predetermined breaking point Has ring step, this ring step can be acted upon by an abutting edge of an abutting collar protruding into this insert cup, a seal is provided between the outer surface of the abutting collar and the further cup wall, the butt collar of the screw cap is molded on and the further insert cup is axially displaceable. In an advantageous manner, the second insert cups have a drive cam formed on the outer cup wall, which is arranged between a drive edge and a stop edge and can be acted upon by them. If only a second insert cup is provided, then the stop edge is formed by an edge of the first insert cup which surrounds the neck opening of the outer container. The drive edge is then formed by the end face of a drive collar assigned to the screw cap. If several nested second insert cups are provided for receiving more than just three components, the drive cam of each second insert cup acts upon the stop edge formed by the upper edge of the insert cup receiving it by further screwing on the screw cap. If this is also a second insert cup, it is axially displaced by the action on the upper edge. The drive cam is arranged such that after the predetermined breaking line of the innermost second insert cup has been broken open, the drive cam is acted upon by the drive edge of the screw cap by further screwing on the screw cap. After the predetermined breaking line of the first insert cup has been separated, its stop edge is acted on by the drive cam of the second insert cup inserted into it by further screwing on the screw cap. The drive cam is advantageously designed such that it surrounds the second insert cup in a ring shape. To achieve an optimal separation of the predetermined breaking line, it is provided that the cross-sectional areas formed by the abutting edge and the ring step extend perpendicular to the axis of rotation of the screw cap. There is also a distance between the abutting edge and the ring step when the screw cap is not screwed on. In order to ensure a secure hold of the screw cap on the outer container even when the screw cap is not screwed on, a circumferential locking edge is provided at the neck opening of the outer container, via which the screw cap is clipped on with an annular bead. Through this and other friction surfaces with the screw cap The outer container and insert cups are difficult to screw on. Unscrewing and the associated separation of the predetermined breaking lines to bring the components together is therefore only possible by deliberately turning the screw cap. The closure cap advantageously has an opening which can be closed with a closure cap. As a result, the screw cap does not need to be removed to remove the component mixture; rather, the removal takes place through all insert cups through the opening of the screw cap. In order to prevent mixing between the predetermined breaking lines of the individual components from one another, a sealing bead is arranged between the cup wall and the butt collar inserted therein. This bulge formed on the cup wall surrounds the butt collar in an exciting manner, that is to say it lies closely so that a radial contact pressure prevails. For the parallel parallel guidance of the axially displaceable second insert cups, two beads arranged in parallel and located on each inside of the cup are provided. This also creates a double seal. The cup base can be pot-shaped. This enables easier production. In order to prevent the webs from shearing off when the protective cap is screwed on further and to ensure that the cup bottoms are effectively folded down after the predetermined breaking lines have been separated, it is provided that the webs, which connect the cup bottom to the cup wall, have a run-up ramp for the abutting edges of the abutting collar when the predetermined breaking line is separated form. Detachment of a cup base from the insert cup is prevented in a simple and safe manner by a web connecting the cup base to the cup wall, which web connects the material when the predetermined breaking line is separated between cup wall and cup bottom.

Im Folgenden wird die Erfindung anhand eines Ausführungsbeispiels im Detail erläutert. Es zeigen:

The invention is explained in detail below using an exemplary embodiment. Show it:

a multi-component pack in half cut in the basic sales position,
Fig. 2
a representation of FIG. 1 but with the screw cap fully screwed on and
Fig. 3
a further embodiment of a screw cap of a multi-component pack.

Die in den Fig. 1 und 2 dargestellte Mehrkomponenten-Packung besteht aus einem Außenbehälter 1, in den ein erster Einsatzbecher 2 eingesteckt ist. Ein zweiter Einsatzbecher 3 findet Aufnahme im ersten Einsatzbecher 2. Auf den Außenbehälter 1 aufgeschraubt ist eine Schraubkappe 4, die eine Öffnung aufweist, die mit einer Verschlußkappe 5 verschlossen ist.The multi-component pack shown in FIGS. 1 and 2 consists of an outer container 1 into which a first insert cup 2 is inserted. A second insert cup 3 is received in the first insert cup 2. A screw cap 4 is screwed onto the outer container 1 and has an opening which is closed with a closure cap 5.

Der erste Einsatzbecher 2 ist in den Außenbehälter 1 derart eingesteckt, daß sein Becherrand 29 die Halsöffnung des Außenbehälters 1 überragt. Der Einsatzbecher 2 ist in den Außenbehälter 1 eingeklipst, so daß eine axiale Verlagerung dieses ersten Einsatzbechers 2 bei normalen Gebrauch der Mehrkomponenten-Packung nicht möglich ist. Vor allem aber soll durch die erwähnte Einklipsung vermieden werden, daß nach dem Füllen des Außenbehälters 1 und dem anschließenden Einstecken des Einsatzbechers 2 durch die dabei auftretende Kompression in der Flasche der Einsatzbecher 2 wieder nach oben springt. Wenn das passieren würde, hätte nach dem Aufsetzen des restlichen Teleskopsystems der Einsatzbecher 2 nicht die richtige Dichtstellung zur Flasche, sprich Außenbehälter 1 oder er würde sich durch das Teleskopsystem in die richtige Dichtstellung drücken, wobei aber dann ungünstigerweise schon die später unten erwähnten Sollbruchstellen vorbeansprucht würden. Daß die Sollbruchstellen Montagearbeit aufnehmen, sollte nicht passieren.The first insert cup 2 is inserted into the outer container 1 in such a way that its cup rim 29 projects beyond the neck opening of the outer container 1. The insert cup 2 is clipped into the outer container 1, so that an axial displacement of this first insert cup 2 is not possible during normal use of the multi-component pack. Above all, however, it should be avoided by the above-mentioned clip-in that after filling the outer container 1 and then inserting the insert cup 2, the insert cup 2 jumps up again due to the compression occurring in the bottle. If this happened, after inserting the rest of the telescope system, the insert cup 2 would not have the correct sealing position with respect to the bottle, i.e. outer container 1, or it would get through the telescope system press into the correct sealing position, but then the predetermined breaking points mentioned later would then be unfavorably pre-stressed. It should not happen that the predetermined breaking points start assembly work.

Der zweite Einsatzbecher 3 steckt mit seinem Stoßkragen 8 in dem ersten Einsatzbecher 2. Der Stoßkragen 8 wird von einer axialen Fortsetzung der Becherwand 21 über den Becherboden 7 hinaus gebildet.The second insert cup 3 is inserted with its butt collar 8 into the first insert cup 2. The butt collar 8 is formed by an axial continuation of the cup wall 21 beyond the cup base 7.

In den zweiten Einsatzbecher 3 ragt der Stoßkragen 9 ein, der mit der Schraubkappe 4 materialeinheitlich verbunden ist.The butt collar 9 projects into the second insert cup 3 and is connected to the screw cap 4 in the same material.

Jede Becherwand 20, 21 weist zwei ringförmige Wülste 16, 17, 18, 19 auf, die der Becherinnenwand ringförmig angeformt sind. Der Innendurchmesser dieser Wülste 16, 17, 18, 19 ist derart bemessen, daß sie die jeweils umschließenden Stoßkragen 8, 9 spannend umgeben und mit einem radialen Druck beaufschlagen, daß eine Abdichtung gebildet ist.Each cup wall 20, 21 has two annular beads 16, 17, 18, 19, which are integrally formed on the cup inner wall. The inside diameter of these beads 16, 17, 18, 19 is dimensioned such that they surround the respective surrounding collars 8, 9 in an exciting manner and apply a radial pressure such that a seal is formed.

Erster Einsatzbecher 2 und zweiter Einsatzbecher 3 weisen je einen topfförmigen Boden 6, 7 auf, der über eine Sollbruchlinie 10, 11 mit der Becherwand 20, 21 verbunden ist. Die Becherböden 6, 7 weisen weiterhin Ringstufen 14, 15 auf, die eine Ebene senkrecht zur Schraubachse der Schraubkappe ausbilden. Parallel zu diesen Ringstufen 14, 15 erstrecken sich in einem Abstand a, b die Stoßkanten 8', 9' der Stoßkragen 8, 9. Abstand a bzw. b entspricht etwa der Wandungsdicke des Becherbodens 6 bzw. 7.The first insert cup 2 and the second insert cup 3 each have a cup-shaped base 6, 7, which is connected to the cup wall 20, 21 via a predetermined breaking line 10, 11. The cup bottoms 6, 7 furthermore have ring steps 14, 15 which form a plane perpendicular to the screw axis of the screw cap. Parallel to these ring steps 14, 15, the abutting edges 8 ', 9' of the abutting collars 8, 9 extend at a distance a, b. Distance a and b corresponds approximately to the wall thickness of the cup base 6 and 7, respectively.

Der zweite Becher 3 ist ferner von einem Antriebsnocken 26 ringförmig umgeben. Der Antriebsnocken ist zwischen der von dem Becherrand 29 des ersten Einsatzbechers 2 gebildeten Anschlagkante und der von der Stirnfläche eines der Schraubkappe 4 zugeordneten Antriebskragens gebildeten Antriebskante 28' angeordnet.The second cup 3 is also surrounded by a drive cam 26 in a ring. The drive cam is arranged between the stop edge formed by the cup edge 29 of the first insert cup 2 and the drive edge 28 ′ formed by the end face of a drive collar assigned to the screw cap 4.

Becherboden 6, 7 und Becherwand 20, 21 sind jeweils durch einen Steg 12, 13 verbunden. Dieser Materialsteg 12, 13 bildet auch bei aufgetrennter Sollbruchlinie 10, 11 eine feste Materialverbindung in Form eines Filmscharnieres zwischen dem Rand des Becherbodens 6, 7 und Becherwand 20, 21.Cup base 6, 7 and cup wall 20, 21 are each connected by a web 12, 13. This material web 12, 13 forms a firm material connection in the form of a film hinge between the edge of the cup base 6, 7 and cup wall 20, 21 even when the predetermined breaking line 10, 11 is separated.

In der Verkaufsgrundstellung greifen nur wenige Gewindegänge der Schraubkappe 4 und des Außenbehälters 1 ineinander. Gegen ein Abschrauben der Schraubkappe 4 vom Außenbehälter 1 ist diese durch einen Rastwulst 25, der die Rastkante 24 des Außenbehälters 1 übergreift, gesichert.In the basic sales position, only a few threads of the screw cap 4 and the outer container 1 interlock. Against unscrewing of the screw cap 4 from the outer container 1, it is secured by a locking bead 25 which engages over the locking edge 24 of the outer container 1.

Wird nun die Schraubkappe 4 weiter aufgeschraubt, so wird der Stoßkragen 9 nach unten verlagert und beaufschlagt mit seiner Stoßkante 9' die Ringstufe 15 des zweiten Einsatzbechers 3. Ein nachfolgendes weiteres Aufschrauben verlagert entweder zunächst den zweiten Einsatzbecher 3 um den Verlagerungsweg a nach unten, so daß die Stoßkante 8' des Stoßkragens 8 die Ringstufe 14 beauf schlagt oder die Ringstufe 15 wird von der Stoßkante 9' derart beaufschlagt, daß die Sollbruchlinie 11 aufgetrennt wird. Nach dem Auftrennen der Sollbruchlinie 11 wird der Stoßkragen 9 weiter nach unten verlagert, wobei er auf die vom Steg 13 gebildete Auflauf schräge aufläuft und den Becherboden 7 nach unten abklappt. Diese Relativbewegung von Stoßkragen 9 zum zweiten Einsatzbecher 3 wird solange fortgesetzt, bis der Antriebsnocken 26 von der Antriebskante 28' des Antriebskragens 28 beaufschlagt wird.If the screw cap 4 is now screwed on further, the butt collar 9 is displaced downward and acts with its abutting edge 9 'on the ring step 15 of the second insert cup 3. Subsequent further screwing either initially displaces the second insert cup 3 by the displacement path a downwards, so that the abutting edge 8 'of the abutting collar 8 strikes the ring step 14 or the ring step 15 is struck by the abutting edge 9' in such a way that the predetermined breaking line 11 is separated. After the predetermined breaking line 11 has been separated, the butt collar 9 is displaced further downward, where it runs obliquely onto the casserole formed by the web 13 and the cup bottom 7 folds downward. This relative movement of the collar 9 to the second insert cup 3 continues until the drive cam 26 is acted upon by the drive edge 28 'of the drive collar 28.

Weiteres Aufschrauben der Schraubkappe 4 führt nun zu einer Beaufschlagung der Ringstufe 14 von der Stoßkante 8' des Stoßkragens 8, bis die Sollbruchlinie 10 des ersten Einsatzbechers aufgetrennt wird. Eine weitere axiale Verlagerung des zweiten Einsatzbechers 3 nach unten führt zu einem Auflaufen des Stoßkragens 8 auf die von dem Steg 12 zusammen mit der Ringstufe 14 gebildete Auflaufschräge und zu einem nachgefolgten Abklappen des Becherbodens 6 zur Seite.Further screwing on the screw cap 4 now leads to the ring step 14 being acted upon by the abutting edge 8 'of the abutting collar 8 until the predetermined breaking line 10 of the first insert cup is separated. A further axial displacement of the second insert cup 3 leads downward to the impact collar 8 running onto the run-up slope formed by the web 12 together with the ring step 14 and to a subsequent folding down of the cup base 6 to the side.

Das Aufschrauben der Schraubkappe 4 läßt sich so weit fortsetzen, bis der Antriebsnocken 26 an der Anschlagkante 27 anschlägt. Dies ist die Stellung, die Fig. 2 darstellt.The screw cap 4 can be screwed on until the drive cam 26 strikes the stop edge 27. This is the position shown in FIG. 2.

Bei der Verschlußkappe 5 in der in den Fig. 1 und 2 dargestellten Ausführungsform handelt es sich um eine aufschraubbare, wiederverschließbare Kappe. Bei der Schraubkappe 4, die in Fig. 3 dargestellt ist, ist die Verschlußkappe 5 der Schraubkappe angeformt und kann zum Öffnen von der Schraubkappenöffnung abgewürgt werden. Trotzdem läßt sich diese hier stopfenartig gestaltete Verschlußkappe 5 wieder schließen, indem der an die entsprechende Sollbruchstelle anschließende obere Abschnitt in die entsprechende Öffnung der Schraubkappe eingedrückt wird. Selbstverständlich können hier auch andere Mittel zur Erzielung der Wiederverschließbarkeit Anwendung finden wie beispielsweise in Form eines Schraubverschlusses.The closure cap 5 in the embodiment shown in FIGS. 1 and 2 is a screw-on, reclosable cap. In the screw cap 4, which is shown in Fig. 3, the cap 5 of the screw cap is formed and can be stalled from the screw cap opening to open. Nevertheless, this stopper-shaped closure cap 5 can be closed again by pressing the upper section adjoining the corresponding predetermined breaking point into the corresponding opening of the screw cap. Of course, other means of achieving resealability can also be used here, for example in the form of a screw cap.

Bei der Version gemäß den Fig. 1 und 2 wird das Abheben der dortigen Verschlußkappe insofern noch als schraubtechnisch bezeichnet, als eine einflankige Steuerung vorliegt, gebildet von aus Fig. 2 ersichtlichen Umfangsrampen, die mit Gegenrampen der dortigen Verschlußkappe 5 zusammenwirken. Das Aufstecken läßt sich dort entsprechend schnell durchführen, da lediglich eine zwischen dem oberen Ende des Stoßkragens 9 und der Verschlußkappe 5 wirkende Steckrast überwunden werden muß. Wie gesagt, kann an die Stelle der Rampenausbildung auch eine klassische Schraubversion treten.In the version according to FIGS. 1 and 2, the lifting off of the closure cap there is still referred to as screwing technology, since there is a single-flank control, formed by circumferential ramps apparent from FIG. 2, which interact with counter ramps of the closure cap 5 there. The attachment can be carried out there correspondingly quickly, since only a push-fit acting between the upper end of the impact collar 9 and the closure cap 5 has to be overcome. As I said, a classic screw version can replace the ramp training.

Die nicht integrale Verschlußkappe 5 besteht aus Polyethylen (PE). Sie ist weicher als die Schraubkappe 4, welche aus Polypropylen (PP) hergestellt ist, der gemäß Fig. 3 die Verschlußkappe 5 gleich angeformt ist. Dagegen ist bezüglich des zweiten, eine Stößelfunktion übernehmenden Einsatzbechers 3 auf die Polyethylenart hart (HDPE) zurückgegriffen, welcher Werkstoff härter ist, als der, aus dem der erste Einsatzbecher 2 gefertigt ist. Letzterer besteht aus Polyethylen weich des Kurzzeichens LDPE. Die als Betätigungshandhabe dienende Schraubkappe 4 ist relativ härter als die beiden Einsatzbecher 2, 3, deren weich-zähes Material das Funktionserfordernis der Filmscharnier-Materialbrücke besonders gut erfüllt.The non-integral cap 5 is made of polyethylene (PE). It is softer than the screw cap 4, which is made of polypropylene (PP), which, according to FIG. 3, has the same sealing cap 5. On the other hand, with regard to the second insert cup 3, which takes over a plunger function, the polyethylene type hard (HDPE) is used, which material is harder than that from which the first insert cup 2 is made. The latter consists of soft polyethylene with the abbreviation LDPE. The screw cap 4 serving as an actuating handle is relatively harder than the two insert cups 2, 3, the soft-tough material of which fulfills the functional requirement of the film hinge material bridge particularly well.
