Description

Einteiliger Kunststoffverschluss One-piece plastic closure
Die vorliegende Erfindung betrifft einen einteiligen Kunststoffverschluss zur Befestigung auf einem Behalterhals mit am Behalterhals vorgesehenen Befestigungsmitteln zur form- und/oder kraftschlussigen Verbindung des Kunststoffverschlusses auf den Behalterhals, wobei der Kunststoffverschluss aus einem Unterteil und einer damit über mindestens ein Film- scharmer schwenkbar verbundenen Kappe besteht, gemass Oberbegriff des Patentanspruches 1.The present invention relates to a one-piece plastic closure for attachment to a neck of the container with fastening means provided on the neck of the container for positive and / or non-positive connection of the plastic closure to the neck of the container, the plastic closure consisting of a lower part and a cap pivotably connected to it via at least one film sharpener , according to the preamble of claim 1.
Insbesondere bei den Verpackungen für Lebensmittel und Kosme- tika werden von den Herstellern immer mehr Anforderungen an die Sicherheit der Verpackung gestellt. Bei den meisten gangigen Verschlüssen wird je nach Typus des Verschlusses mit entsprechenden Mitteln entweder die Verbindung zwischen Verschluss und Behalter gesichert oder Garantieelemente vorgesehen, die die Unversehrtheit des Produktes anzeigen sollen. Wahrend die erstgenannte Variante insbesondere bei Schraubverschlüssen vorgesehen ist, wird die zweitgenannte Ausfuhrungsform vor allem bei Verschlüssen mit einem Klappdeckel vorgesehen. In den allermeisten der letztgenannten Variante handelt es sich um sogenannte Schnappscharmerverschlusse . Die Anmelderin, die Pionierin auf dem Gebiet mehrfach gesicherter Verschlüsse ist, hat in der WO94/03371 bereits einen Klappdeckel-Kunststoffverschluss mit Garantieelement offenbart, bei dem ein Garantieelement einerseits anzeigt, ob die Kappe in Bezug auf den Unterteil des Verschlusses bereits geöffnet worden ist und andererseits auch anzeigt, wenn nach dem Origmalverschliesszustand der gesamte Verschluss vom Behalter entfernt worden ist. Jene Losung arbeitet nicht mit einem Garantieband, sondern mit einem in der Kappenoberflache vorgesehenen, ausreissbaren Siegel, welches sich durch die obere Abdeckflache des Unterteiles hinein erstreckt und mittels einer Arretierungsnase mit den Befestigungsmitteln am Behalterhals form- und kraftschlussig in Eingriff steht. Es hat sich gezeigt, dass diese an sich ausserst elegante Losung herstellungstechnisch ausserst hohe Ansprüche stellt und bei der Montage häufig zu Defekten gerade am Siegel fuhrt. Als weiteres Problem hat sich gezeigt, dass die Zerstörung des Siegels für das Publikum offensichtlich weniger augenfällig ist als ein herkömmliches Garantieband, das weggerissen st.Manufacturers are placing increasing demands on packaging security, particularly for packaging for food and cosmetics. With most common closures, depending on the type of closure, appropriate means are used either to secure the connection between the closure and the container, or to provide guarantee elements that are intended to indicate the integrity of the product. While the first-mentioned variant is intended in particular for screw closures, the second-mentioned embodiment is primarily provided for closures with a hinged lid. Most of the latter variant are so-called snap catch closures. The applicant, who is a pioneer in the field of multi-security closures, already has one in WO94 / 03371 Hinged lid plastic closure with guarantee element disclosed, in which a guarantee element indicates on the one hand whether the cap has already been opened with respect to the lower part of the closure and on the other hand also indicates when the entire closure has been removed from the container after the original closure condition. That solution does not work with a guarantee tape, but with a tear-out seal provided in the cap surface, which extends through the upper cover surface of the lower part and is positively and non-positively engaged with the fastening means on the neck of the holder by means of a locking lug. It has been shown that this solution, which is extremely elegant in itself, places extremely high demands on the production technology and often leads to defects, particularly on the seal, during assembly. Another problem has been shown that the destruction of the seal is obviously less obvious to the public than a conventional guarantee tape that is torn away.
Die Mehrheit der Garantiebander bei Klappscharnierverschlus- sen ist am Unterteil des Verschlusses angeordnet und an der Kappe sind entsprechende Vorsprunge angebracht, die einen Formschluss zwischen Kappe und Garantieband und damit indirekt mit dem Unterteil ermöglichen. Ein einteiliger Kunststoffverschluss gemass Oberbegriff des Patentanspruches 1 geht aus der WO93/00271 hervor. Ausgehend von diesem bekannten Stand der Technik war es die Aufgabe der vorliegenden Erfindung, den bekannten Verschluss derart zu verandern, dass ohne Beifügung weiterer Elemente nur mittels dem Garantieband sowohl eine Sicherung des Verschlusses gegen unerlaubte Oeff- nung als auch gegen Entfernung und nachträgliche Wiederauf- setzung des Verschlusses als einwandfreie und preiswerte Unversehrtheitsgarantie erreicht werden kann.The majority of the guarantee bands for hinged hinge closures are arranged on the lower part of the closure and corresponding projections are attached to the cap, which enable a form fit between the cap and the guarantee band and thus indirectly with the lower part. A one-piece plastic closure according to the preamble of claim 1 is apparent from WO93 / 00271. Based on this known prior art, it was the object of the present invention to change the known closure in such a way that without the addition of further elements only by means of the guarantee tape The lock can be secured against unauthorized opening as well as against removal and subsequent re-installation of the lock as a faultless and inexpensive guarantee of integrity.
Diese Aufgabe lost ein einteiliger Kunststoffverschluss zur Befestigung auf einen entsprechenden Behalterhals mit dem Merkmalen des Patentanspruches 1.This object is achieved by a one-piece plastic closure for attachment to a corresponding neck of the container with the features of claim 1.
Wahrend bisherige Garantiebander immer nur einen Bewegungsgrad eines Verschlusses unterbunden haben, namlich entweder die Möglichkeit einer Schwenkbewegung von Kappe zu Unterteil oder andererseits eine in axiale Richtung des Flaschenhalses gerichtete Bewegungskomponente zur Sicherung des Verschlusses zum Behalter wird hier erstmals das Garantieband so gestaltet, dass es eine Doppelfunktion ausüben kann.While previous guarantee bands only ever prevented a degree of movement of a closure, namely either the possibility of a pivoting movement from cap to lower part or, on the other hand, a movement component directed in the axial direction of the bottle neck to secure the closure to the holder, the guarantee band is designed here for the first time so that it has a double function can exercise.
In der Zeichnung sind zwei Ausfuhrungsbeispiele des Erfindungsgegenstandes detailliert dargestellt. Es zeigt:In the drawing, two exemplary embodiments of the subject matter of the invention are shown in detail. It shows:

Figure 10 shows a section through the neck of the container, which is designed to match the closure according to Figures 7 to 9.
Figur 11 ist eine Ansicht eines zum Verschluss passend gestalteten Behalterhalses.FIG. 11 is a view of a container neck designed to match the closure.
In den Figuren 1 bis 3 erkennt man einen typischen einteiligen Kunststoffverschluss, der aus einem Unterteil 1 und einer, über ein Scharnier 3 damit verbundenen Kappe oder Deckel 2 besteht. Am Deckel ist ein Garantieband 4 angebracht. Der gesamte Verschluss ist auf einem Behalterhals 5 befestigt. Der Behalterhals 5 ist die Mundungsoffnung des Behalters 50.A typical one-piece plastic closure can be seen in FIGS. 1 to 3, which consists of a lower part 1 and a cap or lid 2 connected to it via a hinge 3. A guarantee tape 4 is attached to the lid. The entire closure is attached to a neck 5. The container neck 5 is the mouth opening of the container 50.
Der Unterteil 1 besteht aus einer zylindrischen Mantelwand 11, die oben von einer Deckflache 12 abgeschlossen wird. In der Deckflache 12 ist ein Ausguss 13 m der Gestalt einer Tülle 14 vorhanden. An der Unterseite der Deckflache 12 ist eine ringförmige Wand angeordnet, die eine Dichtlippe 15 bildet und im aufgesetzten Zustand des Verschlusses dichtend an der Innenflache des Behalterhalses 5 anliegt. Zur Befestigung des Verschlusses auf dem Behalterhals sind an der Mantelwand- innenflache entsprechende Befestigungsmittel 54 vorgesehen. Dies können sogenannte Haltewulste sein, die ringförmig angebracht sind oder noppenformig nach innen ragend auf einem einzigen Kreis angeordnete Elemente sein. All diese Befestigungsmittel sind im Stand der Technik in diversen Ausfuhrun- gen bekannt. Im dargestellten Beispiel handelt es sich um ein Gewinde 54.The lower part 1 consists of a cylindrical jacket wall 11 which is closed at the top by a cover surface 12. In the top surface 12 there is a spout 13 m in the shape of a spout 14. An annular wall is arranged on the underside of the cover surface 12, which forms a sealing lip 15 and, when the closure is in place, bears sealingly against the inner surface of the neck 5 of the container. Corresponding fastening means 54 are provided on the inner surface of the jacket wall for fastening the closure on the container neck. These can be so-called retaining beads, which are attached in a ring shape or can be arranged in the form of a knob protruding inwards on a single circle. All of these fasteners are available in various designs in the prior art. gene known. The example shown is a thread 54.
Ueber das Scharnier 3 mit dem Unterteil 1 einstückig gelenkig verbunden ist die Kappe oder Deckel 2 angebracht. Auch die Kappe weist eine zylindrische Mantelwand 21 auf, die ebenso von einer Deckfläche 23 abgeschlossen wird. Auf der Innenfläche der Deckfläche 23 ist ein Dichtzapfen 24 angebracht, der im geschlossenen Zustand des Verschlusses in die Ausgussöffnung 13 dichtend hineingreift. Im erwähnten, geschlossenen Zustand des Verschlusses stehen die Mantelwände 11 beziehungsweise 21 von Unterteil 1 und Kappe 2 fluchtend vertikal übereinander. In der Mantelwand 21 ist eine Einbuchtung vorgesehen, die als Griffmulde 22 dient. Im Bereich dieser Griffmulde 22 fluchtet die Mantelwand 21 des Deckels nicht mit der Mantelwand 11 des Unterteiles. Das Scharnier 3 dient zur Bildung der Schwenkachse 30 und besteht aus einem oder zwei Filmscharnieren 31, an dem seitlich angrenzend Spannelemente 32 vorgesehen sind, die zur Erzielung eines Schnappeffektes dienen.The cap or cover 2 is attached to the lower part 1 in an articulated manner via the hinge 3. The cap also has a cylindrical jacket wall 21, which is likewise closed off by a cover surface 23. On the inner surface of the top surface 23, a sealing pin 24 is attached, which engages sealingly into the pouring opening 13 in the closed state of the closure. In the mentioned, closed state of the closure, the jacket walls 11 and 21 of the lower part 1 and cap 2 are aligned vertically one above the other. An indentation is provided in the jacket wall 21, which serves as a recessed grip 22. In the area of this recessed grip 22, the outer wall 21 of the cover is not aligned with the outer wall 11 of the lower part. The hinge 3 is used to form the pivot axis 30 and consists of one or two film hinges 31, on which laterally adjoining clamping elements 32 are provided, which serve to achieve a snap effect.
An der Kappe 2 ist das Garantieband 4 über die Sollbruchstelle 40 befestigt. Das Garantieband 4 verläuft konzentrisch zur Mantelwand 21 des Deckels 2. Lediglich im Begreif der Griffnische 22 folgt das Garantieband dieser Einbuchtung nicht. Das Garantieband 4 ist im wesentlichen genau um seine Dicke bezüglich der Mantelwand der Kappe nach aussen versetzt angeordnet. Die Verbindung, welche die sogenannte Sollbruch- stelle 40 darstellt, kann entweder als dünne Reissnaht gebildet sein oder durch eine Vielzahl von Stegen geformt werden. In der Figur 1 sind diese Stege 42 symbolisch dargestellt, obwohl diese eigentlich auf der Zeichnung nicht ersichtbar sein wurden. Bei der Ausfuhrung gemass den Figuren 7 bis 9 ist die Sollbruchstelle 40 als Reissnaht 41 bezeichnet. Dem Scharnier 3 diametral gegenüber ist das erwähnte Garantieband 4 angeordnet. Dieses erstreckt sich über maximal annähernd den halben Umfang des Deckels. Wahrend das Garantieband in der Mitte erhöht ist, nimmt seine Hohe seitlich symmetrisch ab. Im Bereich der Nische, welche von der Griffmulde 22 gebildet ist, ist am Garantieband 4 zum Zentrum des Deckels hin ein Zusatzmittel 44 angebracht, das hier die Gestalt einer Lasche 46 aufweist. An der Lasche 46 ist zudem ein Widerhaken 45 angeformt. Dieser Widerhaken 45 erstreckt sich über die gesamte Hohe der Lasche 46. Die Lasche 46 selber ist genau so hoch wie das Garantieband an dieser Stelle. Bei dieser Ausfuhrungsform ist jedoch das Garantieband 4 immer weniger hoch als die Hohe der Mantelwand 11 des Unterteiles 1. Entsprechend ist der Durchbruch 17 im Unterteil 1 von der Deckflache 12 abwärts gerichtet nie so lang, dass die Mantelwand 11 durchtrennt wird.The guarantee band 4 is fastened to the cap 2 via the predetermined breaking point 40. The guarantee band 4 runs concentrically to the jacket wall 21 of the cover 2. Only when the grip niche 22 is understood does the guarantee band not follow this indentation. The guarantee band 4 is essentially offset exactly to the outside with respect to its thickness with respect to the jacket wall of the cap. The connection that the so-called predetermined breaking represents 40, can either be formed as a thin tear seam or formed by a plurality of webs. These webs 42 are shown symbolically in FIG. 1, although they would not actually be visible on the drawing. In the embodiment according to FIGS. 7 to 9, the predetermined breaking point 40 is designated as a tear seam 41. The above-mentioned guarantee band 4 is arranged diametrically opposite the hinge 3. This extends over a maximum of approximately half the circumference of the lid. While the guarantee band is raised in the middle, its height decreases symmetrically on the side. In the area of the niche, which is formed by the recessed grip 22, an additive 44 is attached to the guarantee band 4 towards the center of the cover, which here has the shape of a tab 46. A barb 45 is also formed on the tab 46. This barb 45 extends over the entire height of the tab 46. The tab 46 itself is just as high as the guarantee band at this point. In this embodiment, however, the guarantee band 4 is always less than the height of the jacket wall 11 of the lower part 1. Accordingly, the opening 17 in the lower part 1 directed downward from the cover surface 12 is never so long that the jacket wall 11 is severed.
Beim erstmaligen Schliessen des Verschlusses fahrt die Lasche 46 am Garantieband 4 bei der Schwenkbewegung der Kappe 2 um das Scharnier 3 in den Durchbruch 17 im Unterteil 1 ein. Ist die Kappe 2 vollständig auf das Unterteil schliessend aufgedruckt, so greifen nasenformige Vorsprunge 18, die an der Mantelaussenwand 11 des Unterteiles 1 angeordnet sind, in die bereits erwähnten Formschlussausnehmungen 43 am oberen Rand des Garantiebandes ein. Die erwähnten nasenformigen Vorsprunge 18 an der Mantelwand 11 sind etwa flucntend mit deren oberen Rand angeordnet. In diesem geschlossenen Zustand, wie in Figur 2 dargestellt, wird der Verschluss an den Abfuller geliefert. Dieser füllt entsprechende Behalter ab und schraubt dann den verschlossenen Verschluss auf dem Behalterhals auf. Der Behalterhals weist eine an seiner Peripherie vorgesehene Vertiefung als Formschlussmittel auf. Diese Vertiefung kann praktisch so gestaltet sein, dass das Gewinde 54 am Behalterhals 5 mindestens einseitig scharfkantig unterbrochen ist und so als Formschlussmittel mit der Lasche 44 am Garantieband zusammenwirkt. In der Figur 11 ist ein solcher Behalterhals dargestellt. Am Behalterhals 5 ist das Gewinde 54 deutlich erkennbar. Im Bereich 55 ist das Gewinde unterbrochen, so dass es einseitig eine scharfkantige Formgebung aufweist, welche das eigentliche Formschlussmittel 53 bildet. An der Stelle 56 hingegen steigt das unterbrochene Gewinde rampenformig wieder auf die ursprüngliche Hohe an. Diese Gestaltung erlaubt es, den Verschluss in der Aufdrehrichtung aufzuschrauben, ohne dass dabei die Lasche 44 arretierend mit dem Formschlussmittel 53 zusammenwirkt, wahrend in der Abschraubrichtung die Lasche 44 an der scharf antigen Unterbrechung anzuliegen kommt und somit ein Abschrauben verunmog- licht. Dies ist in den Figuren 4 bis 6 detailliert dargestellt. In der Figur 4 erkennt man, dass die Lasche 44 mit ihrem Widerhaken 45 über das schraffiert dargestellte Gewinde hinweg gleitet. Dank des im Unterteil vorhandenen Durchbruchs 17 st dies bei der Aufsicht auf den Verschluss ersichtlich. Man sieht hier auch deutlich die Ausnehmung 43 im Garantieband 4, sowie den nasenformigen Vorsprung 18, der in dieser Formschlussausnehmung 43 eingreift. Dank der aufeinander abgestimmten Gewinde am Verschluss und am Behalterhals kommt die Lasche 44 im vollständig aufgeschraubten Zustand in den Bereich des beschriebenen Formschlussmittels 53 zu liegen, wie dies in der Figur 5 gezeigt ist. Weiter als die hier dargestellte Lage kann der Verschluss nicht aufgeschraubt werden, weil der Widerhaken 45 an der Lasche 44 nun hinter der Mantelwand des Unterteiles 1 eingreift. Damit ist auch gesichert, dass das Garantieelement nicht durch Ueberschrauben zerstört werden kann. Mochte man hingegen den Verschlussab- schrauben, wie dies in der Figur 6 dargestellt ist, so kommt die Lasche 44 beim Formschlussmittel 53 zum Anschlag. Gleichzeitig ist aber auch der Widerhaken noch mit dem Unterteil im Eingriff, so dass eine vollständige Verriegelung entsteht. Nur wenn man das Garantieband abreisst und dabei die Stege 42 zerstört, lasst sich die Lasche 44 aus ihrer Garantielage entfernen.When the closure is closed for the first time, the tab 46 on the tamper-evident band 4 moves into the opening 17 in the lower part 1 when the cap 2 is pivoted about the hinge 3. If the cap 2 is completely printed onto the lower part, then nose-shaped projections 18 engage on the Sheath outer wall 11 of the lower part 1 are arranged in the already mentioned form-fitting recesses 43 at the upper edge of the guarantee band. The aforementioned nose-shaped projections 18 on the jacket wall 11 are arranged approximately flush with the upper edge thereof. In this closed state, as shown in Figure 2, the closure is delivered to the filler. This fills the appropriate container and then unscrews the closed closure on the neck of the container. The neck of the container has a recess provided on its periphery as a positive locking means. This recess can practically be designed such that the thread 54 on the holder neck 5 is interrupted at least on one side with sharp edges and thus interacts as a form-locking means with the tab 44 on the guarantee band. Such a container neck is shown in FIG. The thread 54 on the neck 5 of the container is clearly recognizable. In the area 55, the thread is interrupted so that it has a sharp-edged shape on one side, which forms the actual form-locking means 53. At point 56, however, the interrupted thread ramps up again to the original height. This design allows the closure to be screwed on in the direction of unscrewing, without the tab 44 interlocking with the form-locking means 53, while in the unscrewing direction the tab 44 comes to rest against the sharp, antidiscipline and thus makes unscrewing impossible. This is shown in detail in FIGS. 4 to 6. In FIG. 4 it can be seen that the tab 44 with its barb 45 over the hatched thread slides away. Thanks to the opening 17 in the lower part, this can be seen when the closure is viewed from above. You can also clearly see the recess 43 in the guarantee band 4, as well as the nose-shaped projection 18 which engages in this form-fitting recess 43. Thanks to the coordinated threads on the closure and on the neck of the holder, the tab 44, when fully screwed on, comes to lie in the area of the form-fitting means 53 described, as shown in FIG. 5. The closure cannot be screwed on further than the position shown here because the barb 45 now engages on the tab 44 behind the outer wall of the lower part 1. This also ensures that the guarantee element cannot be destroyed by unscrewing it. If, on the other hand, one liked the screwing off of the closure, as shown in FIG. 6, the tab 44 comes to a stop with the form-locking means 53. At the same time, the barb is still engaged with the lower part, so that a complete locking is achieved. The tab 44 can only be removed from its guarantee position if the guarantee band is torn off and the webs 42 are destroyed in the process.
Wahrend bei der soeben beschriebenen Losung das erfmdungsge- masse zusätzliche Mittel am Garantieband die Mantelwand des Unterteiles des Verschlusses durchsetzt, wobei in der Garan- tielage ein Formschluss zwischen Garantieband und Unterteil ein Formschluss zwischen dem zusätzlichen Mittel am Garantieband und dem Behalterhals sowie dem Unterteil des Verschlus- ses erfolgt. Die Ausführung gemass den Figuren 7 bis 10 weist dieselbe erfindungsgemässe Lösung auf, doch wird diese mit geänderten Mitteln erzielt. Selbstverständlich ist der generelle Aufbau des Verschlusses identisch. Auch dieser Verschluss besteht aus einem Unterteil 1 und einer einstückig damit über ein Scharnier 3 verbundenen Kappe 2. An der Kappe 2 ist wiederum über eine Sollbruchstelle, die hier als Reissnaht 41 ausgebildet ist, an der Kappenunterkante mindestens annähernd um die Dicke der Bandstärke nach aussen versetzt das Garantieband angeordnet. Das Garantieband 4 ist gegenüber der zuvor beschriebenen Lösung jedoch höher als die Höhe der Mantelwand 11 des Unterteiles 1. Nach innen gerichtet sind an der Unterkante des Garantiebandes 4 mehrere Nocken 44 als zusätzliche Mittel angeformt. Die Formschlussausnehmungen 43 entlang der oberen Kante des Garantiebandes sind ebenfalls noch vorhanden. In der vollständig offenen Position gemass der Figur 7 sind diese Mittel natürlich um 180° gedreht erkennbar, da in diesem Zustand selbstverständlich die Unterkante des Garantiebandes 4 sich in der Zeichnung zuobert befindet. In der strichliniert teilweise gezeichneten geschlossenen Position des Verschlusses überragt der untere Rand des Garantiebandes 4 die Mantelwand 11 des Unterteiles und die erwähnten Nocken 44 vermögen unter die Mantelwand 11 des Unterteils hindurch zu greifen. Der Behälterhals 5 hat im Uebergangsbereich zum Behälter 50 einen Kragen 51, an dem Einrastmittel 52 mindestens etwa entlang dem halben Umfang angeordnet sind. Diese sägezahnformigen Einrastmittel 52 erlauben es, den bereits geschlossenen Verschluss auf dem Be- halterhals 5 des Behalters 50 aufzuschrauben. Die bereits erwähnten Nocken als Zusatzmittel 44 können als nach innen gerichtete Lamellen gestaltet sein, die in der Aufschraubrich- tung ratschenartig über die sagezahnformigen Einrastmittel 52 hinweg bewegbar sind, wahrend in der Schraubrichtung dies verunmoglichst ist. Erst durch die Entfernung des Garantiebandes 4 lasst sich somit auch hier einerseits der Deckel 2 offnen und andererseits der gesamte Verschluss vom Behalterhals 5 abschrauben beziehungsweise entfernen. Gerade bei dieser Losung lassen sich auch problemlos Verschlüsse fertigen, die statt eines Gewindes eine sogenannte Aufsprengwulst aufweisen. In einem solchen Fall brauchen dann die als Nocken 44 ausgestalteten Zusatzmittel nicht mehr als flexible Lamellen ausgestaltet zu sein sondern können relativ rigide geformt sein und praktisch radial nach innen gerichtet sein. Dies ist jedoch für den Fachmann eine absolut bekannte äquivalente Losung. Im Gegensatz zur vorher genannten Ausfuhrung ist diese Variante auch bei relativ grossen Verschlüssen problemlos zu fertigen. Bei kleineren Verschlüssen ist die Variante gemass den Figuren 1 bis 6 eher bevorzugt.While in the solution just described, the additional means according to the invention on the guarantee band penetrates the jacket wall of the lower part of the closure, with a form fit between the guarantee band and lower part a form fit between the additional means on the guarantee band and the holder neck and the lower part of the closure in the guarantee position - this is done. The embodiment according to FIGS. 7 to 10 has the same solution according to the invention, but this is achieved with changed means. Of course, the general structure of the closure is identical. This closure also consists of a lower part 1 and a cap 2 connected in one piece therewith via a hinge 3. The cap 2 is again at least approximately the thickness of the band thickness on the cap edge via a predetermined breaking point, which is designed here as a tear seam 41, on the lower edge of the cap arranged the guarantee tape. Compared to the solution described above, the guarantee band 4 is, however, higher than the height of the jacket wall 11 of the lower part 1. A plurality of cams 44 are formed inward on the lower edge of the guarantee band 4 as additional means. The form-fit recesses 43 along the upper edge of the guarantee band are also still present. In the fully open position according to FIG. 7, these means can of course be seen rotated by 180 °, since in this state the lower edge of the guarantee band 4 is of course located in the drawing. In the closed position of the closure, partly drawn by dashed lines, the lower edge of the guarantee band 4 projects beyond the outer wall 11 of the lower part and the cams 44 mentioned can reach under the outer wall 11 of the lower part. The container neck 5 has a collar 51 in the transition area to the container 50, on which latching means 52 are arranged at least approximately along half the circumference. These sawtooth-shaped latching means 52 make it possible to close the already closed closure on the unscrew the holder neck 5 of the container 50. The cams already mentioned as additional means 44 can be designed as inwardly directed lamellae, which can be moved in a ratchet-like manner in the screw-on direction over the sawtooth-shaped latching means 52, while this is impossible in the screwing direction. Only by removing the guarantee band 4 can the lid 2 be opened on the one hand and the entire closure unscrewed or removed from the holder neck 5 on the other hand. With this solution in particular, closures can also be easily manufactured which have a so-called expansion bead instead of a thread. In such a case, the additional means designed as cams 44 no longer need to be designed as flexible lamellae, but can be of relatively rigid shape and practically directed radially inward. However, this is an absolutely known equivalent solution for the person skilled in the art. In contrast to the previously mentioned version, this variant can also be easily manufactured with relatively large closures. For smaller closures, the variant according to FIGS. 1 to 6 is rather preferred.
Das generelle erfinderische Prinzip ist selbstverständlich auch bei dieser Losung beoibehalten worden. Wahrend bisherige Garantiebander immer nur den Formschluss zwischen Unterteil und Kappe bewerkstelligten, kann hier dank entsprechendem Zu- satznmittel am Garantieband gleichzeitig auch die Verbindung zwischen Garantieband und Behalter beziehungsweise Behalterhals hergestellt werden. Ohne zusatzlich gefertigte Teile oder einen zusätzlichen Montagevorgang wird hiermit ein Kunststoffverschluss angeboten, der eine echte Unversehrtheitsgarantie zu geben vermag. Nicht nur ist sichergestellt, dass der Verschluss vor der Erstingebrauchnahme nicht geöffnet werden kann, noch dass der Verschluss unbemerkt vom Behälter entfernbar ist und folglich an der Ware manipuliert werden kann. Diese Sicherheit praktisch ohne Mehraufwand liess sich mit bekannten Verschlüssen mit Garantieelementen bisher nicht erreichen. The general inventive principle has of course also been retained in this solution. While previous guarantee straps only ever produced the positive connection between the lower part and the cap, the connection between the guarantee strip and the holder or holder neck can also be established here at the same time thanks to the corresponding additive on the guarantee strip. Without additional parts or an additional assembly process is hereby offered a plastic closure, which can give a real guarantee of integrity. It is not only ensured that the closure cannot be opened before first use, nor that the closure can be removed from the container unnoticed and can therefore be manipulated on the goods. This security has so far been practically impossible to achieve with known closures with guarantee elements.
