Abstract

The invention relates to a device for absorbing a liquid by drinking, comprising a pot-shaped mouthpiece of plastic, which has a lateral surface, a base and an oval cross section, wherein two sealing lips extend in the base in the direction of the short oval axis and are separated from each other by a joint line. The wall thickness of the sleeve of the pot-shaped part (1) is greater in the longitudinal area (1.2) that adjoins the base (1.1) than in the longitudinal area (1.3) which is remote from the base. The lateral surface of the pot-shaped part comprises a radially outwardly directed thickened region (1.4) in the transition area to the base (1.1) of the pot-shaped part (1) in the circumferential area at both ends of the short oval axis. With the exception of the thickened region (1.4), the wall thickness (a) of the lateral surface of the pot-shaped part in the longitudinal area (1.2) is greater in the two circumferential areas at both ends of the short oval axis than the wall thickness (b) of said longitudinal area of the lateral surface in the two circumferential areas at both ends of the short oval axis. The base (1.1) of the pot-shaped part (1) is curved towards the inside and reinforced by segments (2.1) which project on the inner side of the base and extend along the slot delimited by the lips (2).

Description

Vorrichtung zur Aufnahme von FlüssigkeitDevice for receiving liquid
Die Erfindung bezieht sich auf eine Vorrichtung zur Aufnahme von Flüssigkeit durch Trinken mit einem topfartigen, im Querschnitt ovalen Mundstück aus Kunststoff, welches einen Mantel und einen Boden aufweist, wobei im Boden entlang der kurzen Ovalachse eine Trennfuge verläuft, an welcher in Schließstellung zwei Dichtlippen aneinander anliegen. Bestimmungsgemäß werden die beiden Dichtlippen durch Zusammendrücken des Mundstückes entlang der kurzen Ovalachse voneinander weg bewegt und die Trennfuge erweitert sich zu einer Trinköffnung. Flüssigkeit fließt vom Inneren des topfartigen Teiles durch die Trinköffnung im Boden nach außen.The invention relates to a device for receiving liquid by drinking with a pot-shaped, oval in cross section mouthpiece made of plastic, which has a jacket and a bottom, wherein in the bottom along the short oval axis a parting line extends, at which in the closed position two sealing lips together issue. According to the invention, the two sealing lips are moved away from each other by compressing the mouthpiece along the short oval axis and the parting line widens to a drinking opening. Liquid flows from the interior of the cup-like part through the drinking opening in the bottom to the outside.
Vorrichtungen dieser Art zeigen die US 2002092877 Al, die EP 1 017 618 Bl und in Ansätzen auch die GB 2 279 130 A.Devices of this type are shown in US 2002092877 A1, EP 1 017 618 B1 and, in batches, also GB 2 279 130 A.
Gemäß der US 20020092877 Al ist der Boden des topfartigen Teils nach Innen gewölbt. Entlang der Dichtlippen ist die Wandstärke des Bodens durch einen an der Außenseite des Bodens vorspringenden Steg verstärkt. Der Mantel des topfartigen Teiles ist an den Umfangsbereichen zwischen denen die größte Breite des topfartigen Teiles eingeschlossen wird über seine ganze Länge mit größerer Wandstärke ausgebildet als der Boden und er ist dabei auch mit größerer Wandstärke ausgebildet als an den Umfangsbereichen zwischen denen die kleinste Breite eingeschlossen wird.According to US 20020092877 Al the bottom of the pot-like part is curved inwards. Along the sealing lips, the wall thickness of the floor is reinforced by a protruding on the outside of the floor web. The shell of the pot-like part is formed at the peripheral regions between which the largest width of the cup-shaped part is formed over its entire length with greater wall thickness than the bottom and he is also formed with greater wall thickness than at the peripheral regions between which the smallest width is included ,
Gemäß der EP 1 017 618 Bl ist der Boden des topfartigen Teils nach Außen gewölbt. Der Mantel des topfartigen Teiles ist an den Bereichen größter Breite des topfartigen Teiles über seine ganze Länge mit größerer Wandstärke ausgebildet als der Boden. In vom Boden entfernt liegenden Bereichen wird die Wandstärke dieser Mantelbereiche gegenüber den dem Boden näher liegenden Mantelbereichen nochmals erhöht. Bei einer Bauvariante ist entlang der Dichtlippen die Wandstärke des Bodens durch einen an der Innenseite des Bodens vorspringenden Steg verstärkt . Bei einer anderen Bauvariante ist die Innenseite der Bodenfläche nach innen gewölbt obwohl die Außenseite des Bodens nach außen gewölbt ist .According to EP 1 017 618 B1, the bottom of the pot-like part is arched to the outside. The shell of the pot-like part is formed at the areas of greatest width of the pot-like part over its entire length with greater wall thickness than the bottom. In regions lying away from the ground, the wall thickness of these jacket regions is increased again in relation to the jacket regions closer to the bottom. In one construction variant, the wall thickness of the floor is reinforced along the sealing lips by a web projecting on the inside of the floor. In another construction variant, the inside of the floor surface is curved inward, although the outside of the floor is curved outward.
Entsprechend der GB 2 279 130 A ist die Mantelfläche des topfartigen Teils kreissymmetrisch und nicht oval. Die Bodenfläche weist durchgehend konstante Dicke auf und ist nach innen gewölbt . Die Mantelfläche und die Bodenfläche haben etwa gleiche Wandstärke. Nur in Bereichen der Mantelfläche, welche von der Bodenfläche weit entfernt liegen ist die Wandstärke erhöht. Der Erfinder hat an den vorbekannten Bauweisen als nachteilig empfunden, dass sie nur gegen sehr geringe Innendrücke zuverlässig schließen und das auch nur dann, wenn sie mit - für Kunst- stoffverarbeitung - sehr hoher Präzision gefertigt sind und aus sehr hochwertigem Material bestehen.According to GB 2 279 130 A, the lateral surface of the pot-like part is circular symmetrical and not oval. The bottom surface has consistently constant thickness and is curved inwards. The lateral surface and the bottom surface have approximately the same wall thickness. Only in areas of the lateral surface, which are far away from the bottom surface, the wall thickness is increased. The inventor has found it disadvantageous in the previously known construction methods that they reliably close only against very low internal pressures and that only if they are manufactured with very high precision for plastics processing and consist of very high-quality material.
Die der Erfindung zu Grunde liegende Aufgabe besteht darin, eine Bauweise für eine Vorrichtung der eingangs geschilderten Art für die Aufnahme von Flüssigkeit durch Trinken vorzuschlagen, bei welcher die Dichtheit auch bei höheren Innendrücken und bei weniger präziser Fertigung aus weniger teuren Materialien gewährleistet werden kann und wobei zudem eine komfortable Handhabbarkeit gegeben ist.The object underlying the invention is to propose a construction for a device of the type described for the absorption of liquid by drinking, in which the tightness can be ensured even at higher internal pressures and less precise production of less expensive materials and wherein In addition, a comfortable handling is given.
Die Aufgabe wird durch die Kombination der Eingangs genannten Merkmale mit der Kombination folgender weiterer Merkmale gelöst :The task is solved by combining the aforementioned features with the combination of the following additional features:
- Die Wandstärke des Mantels des topfartigen Teils ist an dem an den Boden angrenzenden Längsbereich größer als an dem vom Boden beabstandeten Längsbereich.The wall thickness of the shell of the pot-like part is greater at the longitudinal region adjacent to the bottom than at the longitudinal region spaced from the bottom.
- Am Übergangsbereich zum Boden des topfartigen Teils weist die Mantelfläche des topfartigen Teils im Bereich der beiden Enden der kurzen Ovalachse jeweils eine radial nach außen gerichtete Verdickung auf .- At the transition region to the bottom of the cup-shaped part, the lateral surface of the cup-shaped part in the region of the two ends of the short oval axis in each case a radially outwardly directed thickening.
- Zwischen jenem Längsbereich des Mantels des topfartigen Teils, welcher dem Boden gegenüber liegt und dünne Wandstärke aufweist und jenem Längsbereich des Mantels, an welchem die besagten, nach außen gerichteten Verdickungen liegen, ist die Wandstärke des Mantels an den Endbereichen der langen Ovalachse größer als an den Endbereichen der kurzen Ovalachse.The wall thickness of the jacket at the end regions of the long oval axis is greater than that between that longitudinal region of the jacket of the pot-like part, which lies opposite the bottom and has thin wall thickness and that longitudinal region of the jacket on which the said, outwardly directed thickenings the end portions of the short oval axis.
- An der Außenseite ist der Boden des topfartigen Teils konkav gewölbt und der Boden ist entlang der Dichtlippen durch einen an der Innenseite des Bodens vorspringenden Steg verstärkt .- On the outside of the bottom of the pot-like part is concavely arched and the bottom is reinforced along the sealing lips by a protruding on the inside of the bottom web.
Durch diese Bauweise wird den im interessierenden Bereich auch nichtlinearen Elastizitäts- und Verformungseigenschaften des verwendeten Kunststoffs extrem gut Rechnung getragen.By this construction, the nonlinear elasticity and deformation properties of the plastic used in the field of interest are extremely well taken into account.
Die Erfindung und vorteilhafte Weiterentwicklungen dazu werden an Hand von Zeichnungen einer beispielhaften erfindungsgemäßen Vorrichtung veranschaulicht.The invention and advantageous developments thereof are illustrated by means of drawings of an exemplary device according to the invention.
Fig. 1: zeigt eine beispielhafte erfindungsgemäße Vorrichtung mit Blickrichtung von außen auf den Boden des topfartigen Teils. Fig. 2: zeigt eine Schnittansicht der Vorrichtung von Fig. 1 entlang der Schnittebene A-A gemäß Fig. 1. In punktierten Linien ist die wesentliche Verformung des Bodens bei geöffnetem Zustand angedeutet .Fig. 1: shows an exemplary device according to the invention with a view from the outside on the bottom of the pot-like part. 2 shows a sectional view of the device of FIG. 1 along the sectional plane AA according to FIG. 1. Dotted lines indicate the essential deformation of the bottom when it is open.
Fig. 3: zeigt eine Schnittansicht der Vorrichtung von Fig. 1 entlang der Schnittebene B-B gemäß Fig. 1.3 shows a sectional view of the device of FIG. 1 along the sectional plane B-B according to FIG. 1.
Im dargestellten Beispiel weist der aus Boden 1.1 und Mantel 1.2, 1.3 bestehende topfartige Teil 1 der erfindungsgemäßen Vorrichtung an der dem Boden abgewandten Seite des Mantels eine ringartige Erweiterung 3 auf, mit Hilfe derer er am Rand einer Öffnung in einer Fläche 10 abgestützt sein kann, welche typischerweise Teil eines größeren Behältnisses wie einer Getränkeflasche oder Teil der Deckfläche eines Schraubverschlusses ist.In the example shown, the bottom of 1.1 and 1.2, 1.3 existing cup-like part of the device according to the invention on the side facing away from the bottom of the shell on a ring-like extension 3, by means of which he can be supported on the edge of an opening in a surface 10, which is typically part of a larger container such as a beverage bottle or part of the top surface of a screw cap.
In der Erweiterung 3 kann ein als Rückschlagventil ausgebildetes Belüftungsventil 4 angeordnet sein, durch welches hindurch Luft in ein starres Behältnis einfließen kann, wenn bestimmungsgemäß Flüssigkeit durch die Öffnung zwischen den Lippen 2 ausfließt. Aus Gründen der Haltbarkeit der Flüssigkeit ist es besser, ein zusammenfaltbares oder sonst irgendwie im Volumen verkleinerbares Behältnis, typischerweise einen Beutel, anstatt eines starren Gefäßes zu verwenden und kein Belüftungsventil 4 vorzusehen - was im Rahmen der Erfindung problemlos möglich ist. Indem sich das Volumen des Behältnisses während der Flüssigkeitsentnahme um das Volumen der entnommenen Flüssigkeit verringert, braucht keine Luft in das Behältnis zu gelangen. Dadurch werden keine Keime in das Behältnis gebracht und es kommt auch nicht zu Oxidation der Flüssigkeit .In extension 3, a vent valve 4 designed as a check valve can be arranged, through which air can flow into a rigid container when liquid flows out through the opening between the lips 2 as intended. For reasons of durability of the liquid, it is better to use a collapsible or otherwise somehow volume reducible container, typically a bag, instead of a rigid container and not provide a vent valve 4 - which is easily possible within the scope of the invention. By reducing the volume of the container during the liquid removal by the volume of the withdrawn liquid, no air needs to get into the container. As a result, no germs are brought into the container and it does not come to oxidation of the liquid.
Anstatt die Vorrichtung an ihrem vom Boden abgewandten Ende wie dargestellt für den Einsatz an einer Öffnung einer breiteren Fläche 10 zu verbreitern, könnte man sie dort auch für das Verbinden mit einem schmäleren Schlauch oder Trinkhalm verjüngen.Instead of widening the device at its end facing away from the bottom as shown for use at an opening of a wider area 10, one could also rejuvenate it there for connection to a narrower hose or straw.
Wie in Fig. 2 und in Fig. 3 gut erkennbar, weist die Mantelfläche des topfartigen Teils im Wesentlichen zwei Längsbereiche auf die sich durch verschiedene Wandstärken voneinander unterscheiden. Vom Boden 1.1 aus bis etwa zur Hälfte der Länge des Mantels erstreckt sich der Längsbereich 1.2, welcher wesentlich größere Wandstärke aufweist als der vom Boden 1.1 abgewandt liegende Längsbereich 1.3. Der Übergang zwischen den beiden Wandstärkenbereichen ist idealerweise wie dargestellt fließend und nicht abrupt . Der Längsbereich 1.2 der Mantelfläche weist in sich allerdings auch nicht durchgehend die gleiche Wandstärke auf. Fig. 2 ist eine Schnittansicht, bei welcher die Schnittfläche parallel zur langen Ovalachse durch den topfartigen Teil 1 verläuft. Die dabei sichtbare Wandstärke „a" der Mantelfläche im Längsbereich 1.2 an jenen beiden Umfangsbereichen der Mantelfläche welche zwischen sich die größte Breite des topfartigen Teils 1 einschließen ist größer als die in Fig. 3 sichtbare Wandstärke „b" der in Umfangs- richtung um eine Vierteldrehung versetzten Mantelflächenteile, welche zwischen sich die kleinste Breite des topfartigen Teils 1 einschließen. Idealerweise sind die Übergänge der Wandstärken zwischen den Werten a und b über den Umfangsverlauf der Mantel- flächenteile 1.2 fließend und nicht abrupt.As can be clearly seen in FIG. 2 and in FIG. 3, the lateral surface of the pot-shaped part has essentially two longitudinal regions, which differ from one another by different wall thicknesses. From the bottom 1.1 to about half of the length of the shell extends the longitudinal region 1.2, which has substantially greater wall thickness than the side facing away from the bottom 1.1 longitudinal region 1.3. The transition between the two wall thickness ranges is ideally fluid, as illustrated, and not abrupt. However, the longitudinal region 1.2 of the lateral surface in itself does not have the same wall thickness throughout. FIG. 2 is a sectional view in which the sectional surface is parallel to the long oval axis through the pot-like member 1. As shown in FIG. The visible wall thickness "a" of the lateral surface in the longitudinal region 1.2 at those two peripheral regions of the lateral surface which enclose between them the largest width of the cup-shaped part 1 is greater than the visible in Fig. 3 wall thickness "b" in the circumferential direction by a quarter turn offset lateral surface parts, which include the smallest width of the cup-shaped part 1 between them. Ideally, the transitions of the wall thicknesses between the values a and b over the circumferential course of the lateral surface parts 1.2 are fluid and not abrupt.
Idealerweise sind die gezeigten Wandstärken a und b, welche Extremwerte der Wandstärke der Mantelfläche im Längsbereich 1.2 darstellen, größer als die Wandstärke der Bodenfläche 1.1 - mit Ausnahme jener Teile an denen diese durch Stege 2.1 verstärkt ist.Ideally, the wall thicknesses shown a and b, which represent extreme values of the wall thickness of the lateral surface in the longitudinal region 1.2, greater than the wall thickness of the bottom surface 1.1 - with the exception of those parts where this is reinforced by webs 2.1.
Nur am Übergangsbereich zum Boden 1.1 des topfartigen Teils weist die Mantelfläche des topfartigen Teils im Bereich der beiden Enden der kurzen Ovalachse jeweils eine radial nach außen gerichtete Verdickung 1.4 auf (Fig. 1, Fig. 3) .Only at the transition region to the bottom 1.1 of the pot-like part, the lateral surface of the cup-shaped part in the region of the two ends of the short oval axis in each case a radially outwardly directed thickening 1.4 (Fig. 1, Fig. 3).
Bestimmungsgemäß werden zwecks Öffnen der Lippen 2 im Boden 1.1 die beiden flacheren Umfangsbereiche der Mantelfläche aneinander- gedrückt, indem die Wandbereiche mit der in Fig. 3 eingezeichneten Wandstärke „bu durch äußere Druckkraft aufeinander zu bewegt werden. Die besprochen Kombination von Dicken der Wandstärken vor allem der Mantelfläche des topfartigen Teils aber auch von dessen Bodenfläche bewirken einerseits gutes Dichthalten der Vorrichtung, andererseits auch vorteilhaft weites Öffnen der Lippen 2 nach außen hin, wenn besagte äußere Druckkraft aufgebracht wird.According to the definition, in order to open the lips 2 in the base 1.1, the two flatter peripheral regions of the lateral surface are pressed against one another by the wall regions being moved toward one another by the external wall pressure with the wall thickness "b u drawn in FIG. The discussed combination of thicknesses of the wall thicknesses, in particular the lateral surface of the pot-like part but also of the bottom surface cause on the one hand good sealing of the device, on the other hand also advantageous wide opening of the lips 2 to the outside, when said external pressure force is applied.
Für die Anwendung als Trinköffnung für ein Gefäß wird die besagte äußere Druckkraft durch die Zähne, Lippen oder Finger der trinkenden Person aufgebracht. Die Zähne, Lippen oder Finger können dabei gut an den Übergängen der Verdickungen 1.4 zum „normalen" Längsbereich 1.2 der Mantelfläche ansetzen.For use as a drinking opening for a vessel said external pressure force is applied by the teeth, lips or fingers of the person drinking. The teeth, lips or fingers can do well at the transitions of the thickenings 1.4 to the "normal" longitudinal region 1.2 of the lateral surface.
Für die zuverlässige Dichtheit auch bei Innendrücken bis zu mehreren bar ist auch die Form des Bodens 1.1 und der Geometrie im Bereich der Lippen 2 von entscheidender Wichtigkeit. Es ist wichtig, dass der Boden 1.1 nach innen gewölbt ist. Innendruck trach- tet die Wölbung des Bodens zu verringern. Da auf Grund der hohen Wandstärken der Mantelfläche im Bereich des Randes des Bodens, der Umfang des Bodens dabei nicht oder kaum vergrößert werden kann, wird der Mittelteil des Bodens dabei unter Druckspannung mit zur Fläche des Bodens parallel liegender Spannungskomponente gesetzt. D.h., die beiden Lippen 2 werden aneinander gepresst. Dieses Aneinanderpressen wird durch die innen liegenden Stege 2.1 an den Lippen 2 verstärkt. Da das verwendete Material relativ weichelastisch ist und im elastischen Bereich gut verformbar ist, bewirkt dieses Aneinanderpressen der Stege 2.1 einen großflächigen Kontakt der Stege 2.1 aneinander und damit eine gute Dicht- Wirkung .For the reliable tightness even with internal pressures up to several bar, the shape of the bottom 1.1 and the geometry in the region of the lips 2 is of crucial importance. It is important that the bottom 1.1 is curved inwards. Internal pressure trach- to reduce the curvature of the soil. Since due to the high wall thicknesses of the lateral surface in the region of the edge of the soil, the circumference of the soil can not or hardly be increased, the middle part of the soil is placed under compressive stress with the surface of the soil lying parallel stress component. That is, the two lips 2 are pressed together. This juxtaposition is reinforced by the inner webs 2.1 on the lips 2. Since the material used is relatively soft elastic and is well deformed in the elastic region, this pressing together of the webs 2.1 causes a large-area contact of the webs 2.1 together and thus a good sealing effect.
Eine besondere Dichtwirkung wird auch dadurch erreicht, dass die Höhe „h" der beiden Stege 2.1 größer ist als deren Breite „d" (Fig. 2) . Durch diese Maßnahme werden die beiden Stege nicht nur durch Verformung des Bodens 1.1 aneinander gedrückt, sondern maßgeblich auch direkt durch den im Inneren des topfartigen Teiles herrschenden Fluiddruck, indem dieser an den zur Schlitzfläche parallelen, der Schlitzfläche abgewandten Flächen der Stege 2.1 an diese andrückt und so die beiden Stege aneinander drückt . Vorteilhaft an den Stegen 2.1 ist auch, dass sie den Boden 1.1, welcher gegen den Innendruck ein Gewölbe darstellt, aussteifen.A special sealing effect is also achieved in that the height "h" of the two webs 2.1 is greater than the width "d" (FIG. 2). By this measure, the two webs are pressed against each other not only by deformation of the bottom 1.1, but also directly by the pressure prevailing in the interior of the cup-shaped part fluid pressure by this at the slot surface parallel to the slot surface faces away from the webs 2.1 presses against this and so the two bars pressed together. An advantage of the webs 2.1 is also that they stiffen the bottom 1.1, which represents a vault against the internal pressure.
Bei einer beispielhaften, als im Bereich des typischen anzusehenden Dimensionierung einer erfindungsgemäßen Vorrichtung, beträgt der Durchmesser des topfartigen Teils in Richtung der längeren Ovalachse etwa 19 mm und in Richtung der kürzeren Ovalachse etwa 14 mm. Die weiteren beispielhaften und typischen Maße können maßstäblich aus den Zeichnungen Fig. 1 bis Fig. 3 entnommen werden. Als Kunststoffmaterial für die Vorrichtung eignen sich thermoplastische Elastomere (TPE) recht gut. Sie können gut durch Spritzgießen in die dargestellte Form gebracht werden. Der Schlitz zwischen den Lippen 2 kann durch einen an den Spritzgießvorgang anschließenden SchneideVorgang hergestellt werden. Mit den gegebenen Dimensionierungsregeln und dem angegebenen Material kann die erfindungsgemäße Vorrichtung so kostengünstig hergestellt werden, dass sie als gemeinsam mit einem Getränk verkauftes Einwegprodukt vermarktbar ist .In an exemplary dimensioning of a device according to the invention which is to be regarded as typical, the diameter of the cup-shaped part is approximately 19 mm in the direction of the longer oval axis and approximately 14 mm in the direction of the shorter oval axis. The further exemplary and typical dimensions can be taken to scale from the drawings Fig. 1 to Fig. 3. As a plastic material for the device, thermoplastic elastomers (TPE) are quite good. They can be well brought by injection molding in the illustrated form. The slot between the lips 2 can be made by a subsequent to the injection molding cutting process. With the given dimensioning rules and the specified material, the device according to the invention can be manufactured so inexpensively that it can be marketed as a disposable product sold together with a beverage.
Die in Fig. 1 strichliert eingezeichneten Linien 20 markieren jene Oberflächenbereiche des topfartigen Teils 1 an welchen bei dem zu seiner Herstellung dienenden SpritzgussVorgang der Anspritz- punkt liegen sollte. Der Anspritzpunkt sollte keineswegs zu nahe am Boden 1.1 oder in dessen Nahbereich sein, da dort die mit dem Anspritzpunkt einhergehende Unebenheit stören würde. Von Wichtigkeit ist weiters, den Anspritzpunkt am Endbereich einer langen Ovalachse des im Querschnitt ovalen topfartigen Teils 1 zu setzen. Damit wird erreicht, dass in dem Volumenbereich, in welchem der Schlitz 2 durch nachträgliches Schneiden gebildet wird, das Material während des Spritzgussvorganges quer zur Schlitzrichtung fließt. Damit wird ein vorteilhaftes Verformungsverhalten des Topfes 1 erreicht. (Die Elastizitätseigenschaften der für den Topf 1 verwendbaren Kunststoffmaterialien, insbesondere von TPE, sind in der Hinsicht anisotrop, dass sie unterschiedlich sind ob sie längs oder quer zur Richtung einer vorangegangenen plastischen Verformung gemessen werden.)The dashed lines 20 in FIG. 1 mark those surface areas of the pot-like part 1 on which the injection point should be located in the injection molding process used for its production. The injection point should not be too close be on the ground 1.1 or in its vicinity, since there would interfere with the associated with the injection point unevenness. It is also important to set the injection point at the end region of a long oval axis of the oval-shaped cup-shaped part 1. This ensures that in the volume region in which the slot 2 is formed by subsequent cutting, the material flows during the injection molding process transversely to the slot direction. For an advantageous deformation behavior of the pot 1 is achieved. (The elasticity properties of the plastic materials usable for the pot 1, in particular TPE, are anisotropic in that they are different as to whether they are measured longitudinally or transversely to the direction of a previous plastic deformation.)
In einer vorteilhaften Ausführungsform wird die erfindungsgemäße Vorrichtung einstückig mit einem Schraubverschluss - von dem in Fig. 2 und Fig. 3 die Deckfläche 10 angedeutet ist - und daran schwenkbar angeordneter Schutzkappe ausgebildet. Schraubverschluss und Schutzkappe sind dabei idealerweise aus einem steiferen Kunststoff gebildet als die erfindungsgemäße Vorrichtung. In einer vorteilhaften, weil einfachen Verfahrensweise, werden dazu die Teile unterschiedlichen Materials aus Thermoplasten gebildet und durch Zweikomponentenspritzguss miteinander verbunden. In an advantageous embodiment, the device according to the invention is integrally formed with a screw cap - of which in Fig. 2 and Fig. 3, the top surface 10 is indicated - and formed pivotally mounted protective cap. Screw cap and protective cap are ideally made of a stiffer plastic than the device according to the invention. In an advantageous, because simple procedure, to the parts of different material are formed from thermoplastic and joined together by two-component injection molding.
