Abstract

A one piece plastic closure comprises a base which is attachable to a container and a cap attached to the base of the closure by a hinge. A safety band is molded together with the base, to which it may be attached by webs. The safety band overlays approximately half the perimeter of the cap and its height is generally the same as that of the cap itself. In this way, the cap cannot be grasped in the area opposite the hinge, and thus cannot be opened. A lug may additionally be provided on the cap which is engageable in a corresponding recess in the safety band to provide the closure in a closed and sealed condition, thus holding the closure and preventing it from opening under the effect of excess pressure in the container.

Description

Garantiebänder an Kunststoffverschlüssen dienen als Unversehrtheitsgarantie für ein in einem Behälter mit Kunststoffverschluss verpacktes Produkt. Bisher wurden Garantiebänder meist nur bei zweiteiligen Kunststoffverschlüssen verwendet. Bei solchen Verschlüssen, die aus einem getrennten Unterteil und einer darauf aufsetzbaren Kappe bestehen, ist das Garantieband über Stege mit dem Unterteil verbunden und umschlingt den Verschluss vollständig, das heisst um 360 Grad.Guarantee tapes on plastic closures serve as a guarantee of integrity for a product packaged in a container with a plastic closure. So far, guarantee tapes have mostly only been used for two-part plastic closures. In the case of such closures, which consist of a separate lower part and a cap which can be placed thereon, the guarantee band is connected to the lower part via webs and completely wraps around the closure, that is to say by 360 degrees.

Am Garantieband angeordnete Formschlussmittel machen das Oeffnen der Kappe unmöglich, bevor das Garantieband abgerissen ist. Das Garantieband kann auch an der Kappe befestigt sein und formschlüssig in das Unterteil eingreifen. Schliesslich sind auch Lösungen bekannt, bei denen das Garantieband am Unterteil angespritzt und so weit hochgezogen ist, dass ein Zugriff zur Kappe unmöglich ist, bevor nicht das Garantieband entfernt wurde.Form-locking means arranged on the guarantee band make it impossible to open the cap before the guarantee band is torn off. The guarantee band can also be attached to the cap and engage in a form-fitting manner in the lower part. Finally, solutions are also known in which the guarantee band is molded onto the lower part and pulled up so far that access to the cap is impossible, before the guarantee tape has been removed.

Die vorliegende Erfindung betrifft einen Kunststoffverschluss, bestehend aus einem Unterteil und einer einstückig über ein Scharnier damit verbundenen Kappe und einem am Verschlussunterteil angeordneten Garantieband.The present invention relates to a plastic closure, consisting of a lower part and a cap connected in one piece via a hinge, and a guarantee band arranged on the lower part of the closure.

Aus der US-A-4.487.324 ist ein solcher Verschluss bekannt geworden, bei dem das Garantieband mit Durchbrüchen versehen ist, in die an der Kappe angebrachte Nocken eingreifen und ein Oeffnen des Verschlusses unmöglich machen, obwohl der Griff zum Oeffnen der Kappe zugänglich ist.Such a closure has become known from US-A-4,487,324, in which the guarantee band is provided with openings, into which cams attached to the cap engage and make it impossible to open the closure, although the handle for opening the cap is accessible .

Beim erstmaligen Schliessen wird das Garantieband relativ stark verformt, bevor die Nocken in die Durchbrüche eingreifen. Dabei besteht die Gefahr, dass die Sollbruchstellen zwischen dem Garantieband und dem Unterteil ungewollt zerrissen werden.When it is closed for the first time, the guarantee band is deformed relatively strongly before the cams engage in the openings. There is a risk that the predetermined breaking points between the guarantee band and the lower part will be unintentionally torn.

Die FR-A-2.113.896 bezieht sich auf einen Verschluss, bei dem das Garantieband einen Durchbruch aufweist, der in geschlossenem Zustand des Verschlusses den Griff der Kappe fasst. Auch bei diesem Verschlusss tritt beim erstmaligen Schliessen eine starke Deformation des Garantiebandes auf.FR-A-2.113.896 relates to a closure in which the guarantee band has an opening which, when the closure is closed, grips the handle of the cap. With this closure, too, a strong deformation of the guarantee band occurs when it is closed for the first time.

Es ist die Aufgabe der vorliegenden Erfindung, einen Kunststoffverschluss gemäss Oberbegriff des Patentanspruches mit Garantieband zu schaffen, der besonders einfach und preiswert ist.It is the object of the present invention to provide a plastic closure according to the preamble of the claim with a guarantee band, which is particularly simple and inexpensive.

Die Erfindung löst diese Aufgabe mit einem Kunststoffverschluss, der die Merkmale des Patentanspruches 1 aufweist.The invention solves this problem with a plastic closure, which has the features of claim 1.

Dadurch, dass das Garantieband sich nur über den halben Umfang der Kappe erstreckt, werden beim erstmaligen Schliessen überhaupt keine Kräfte auf das Garantieband ausgeübt. Damit ist die Gefahr eines ungewollten Zerreissens der Sollbruchstellen gebannt.The fact that the guarantee band only extends over half the circumference of the cap means that no forces are exerted on the guarantee band when it is closed for the first time. This eliminates the risk of unwanted tearing of the predetermined breaking points.

Eine weitere vorteilhafte Ausgestaltungsform sieht vor, dass in der Kappe eine seitliche, in die Kappenoberfläche auslaufende Griffmulde geformt ist. Diese Vertiefung ermöglicht es, das Garantieband zu ergreifen, auch ohne dass dieses eine zusätzliche Aufreisslasche aufweist. Ein weiterer Vorteil besteht darin, dass das so ergriffene Garantieband schräg nach unten abgerissen wird, wodurch die Kerbwirkung am Material im Bereich der Sollbruchstege vergrössert wird.A further advantageous embodiment provides that a lateral recessed grip that runs into the cap surface is formed in the cap. This recess makes it possible to grasp the guarantee band, even without this having an additional tear-open tab. Another advantage is that the guarantee tape gripped in this way is torn off obliquely downwards, thereby increasing the notch effect on the material in the area of the predetermined breaking webs.

Liegt das Garantieband möglichst nahe an der Kappe an, so ist die Gefahr, dass das Garantieband unabsichtlich versehrt wird, gering. Dies kann dadurch erreicht werden, dass das Garantieband über Stege mit dem Verschlussunterteil verbunden ist, deren Länge mindestens annähernd der Materialdicke des Garantiebandes entspricht.If the guarantee band is as close as possible to the cap, the risk of the guarantee band being accidentally broken is minimal. This can be achieved in that the guarantee band is connected to the lower closure part via webs, the length of which corresponds at least approximately to the material thickness of the guarantee band.

Diese Gestaltungsform des Garantiebandes bewirkt beim Abreissen desselben immer eine senkrecht zur Stegrichtung verlaufende Kraftkomponente. Diese Kraftkomponente bewirkt eine grosse Kerbwirkung auf die Stege, mittels denen das Garantieband am Unterteil befestigt ist. Diese scheinbar unwesentliche Tatsache ermöglicht es, erstmals einen Kunststoffverschluss mit Garantieband aus Polypropylen zu fertigen.This design of the guarantee tape always results in a force component running perpendicular to the web direction when it is torn off. This force component causes a large notch effect on the webs, by means of which the guarantee tape is attached to the lower part. This apparently insignificant fact makes it possible for the first time to manufacture a plastic closure with a guarantee tape made of polypropylene.

In den Figuren 1-5 ist ein und derselbe Verschluss in verschiedenen Ansichten dargestellt, wobei in den Figuren 1-4 das Garantieband vorhanden, in Figur 5 dasselbe abgerissen ist. Der Verschluss besteht aus einem Unterteil 1, einer Kappe 2 und einem die beiden Teile schwenkbar verbindenden Scharnier 3. Ein am Unterteil 1 angespritztes Garantieband ist mit 4 bezeichnet. Das Garantieband 4 ist dem Scharnier 3 gegenüber gelegen und erstreckt sich um den halben Umgang der Kappe. Das Garantieband 4 ist gegenüber dem Scharnier 3 symmetrisch diametral ausgerichtet. Die Höhe des Garantiebandes 4 entspricht etwa der Höhe der Kappe 2. Der obere Rand der Kappe 2 ist gerundet, und die Rundung 5 geht erst unterhalb der Oberkante des Garantiebandes in die vertikale, zylindrische Wand der Kappe über.FIGS. 1-5 show one and the same closure in different views, the guarantee band being present in FIGS. 1-4, the same being torn off in FIG. 5. The closure consists of a lower part 1, a cap 2 and a hinge 3 pivotally connecting the two parts. A guarantee band molded onto the lower part 1 is designated by 4. The guarantee band 4 is located opposite the hinge 3 and extends halfway around the cap. The guarantee band 4 is aligned symmetrically diametrically with respect to the hinge 3. The height of the guarantee band 4 corresponds approximately to the height of the cap 2. The upper edge of the cap 2 is rounded, and the curve 5 merges into the vertical, cylindrical wall of the cap only below the upper edge of the guarantee band.

Ein geringer oberer Randbereich des Garantiebandes 4 kann somit erfasst werden. Dies ermöglicht es, ein Ende des Garantiebandes zu fassen und in radial nach unten gerichteter Richtung abzureissen. Eine andere Art, das Garantieband 4 zu entfernen, besteht darin, dass man mit dem Daumen diagonal über die Kappe 2 vom Scharnier 3 weg hinüberstreicht und dabei das Garantieband 4 nach unten abstreift.A small upper edge area of the guarantee band 4 can thus be detected. This makes it possible to grasp one end of the guarantee band and tear it off in a radially downward direction. Another way to remove the guarantee tape 4 is to slide your thumb diagonally over the cap 2 away from the hinge 3 and to strip the guarantee tape 4 downwards.

Diese Art der Oeffnung ist insbesondere dann möglich, wenn der Verschluss aus Polypropylen gefertigt ist. Polypropylen weist dank seiner Macromolekül-Struktur einen relativ hohen Elastizitätsmodul, jedoch eine relativ geringe Kerbschlagzähigkeit auf. Die Gestaltung des Garantiebandes, die Verbindung des Bandes über Stege mit dem Unterteil und das Fehlen einer Aufreisslasche bewirken beim Entfernen des Garantiebandes immer eine grosse Kerbwirkung auf das Material . Nur aus diesem Grunde ist es erstmals möglich, einen Kunststoffverschluss mit Garantieband aus Polypropylen zu verwenden. Die Stege 6, mit denen das Garantieband mit dem Unterteil 1 verbunden ist, sind lediglich in Figur 4 erkennbar. Sie liegen annähernd in der Trennebene zwischen Kappe 2 und Unterteil 1 und werden in Seitenansicht durch das Garantieband 4 verdeckt.This type of opening is particularly possible if the closure is made of polypropylene. Thanks to its macromolecular structure, polypropylene has a relatively high modulus of elasticity, but a relatively low impact strength. The design of the guarantee band, the connection of the band via webs to the lower part and the lack of a tear-open tab always result in a large notch effect on the material when the guarantee band is removed. This is the only reason why it is possible for the first time to use a plastic closure with a polypropylene guarantee band. The webs 6, with which the guarantee band is connected to the lower part 1, can only be seen in FIG. 4. They are approximately in the parting plane between cap 2 and lower part 1 and are covered in side view by the guarantee band 4.

Ohne das Garantieband 4 zu entfernen, lässt sich die Kappe 2 nicht fassen und somit auch nicht öffnen. Das Garantieband 4 verdeckt auch eine Oeffnungshilfe in Form einer Drückmulde 7. Dieselbe ist in den Figuren 2 und 5 ersichtlich. Figur 5 zeigt den Verschluss in geöffneter Lage, bei dem das Garantieband bereits entfernt wurde und die Mulde 7 deutlich sichtbar ist.Without removing the guarantee tape 4, the cap 2 cannot be grasped and therefore cannot be opened. The guarantee band 4 also hides an opening aid in the form of a pressure trough 7. The same can be seen in FIGS. 2 and 5. Figure 5 shows the closure in the open position, in which the guarantee tape has already been removed and the trough 7 is clearly visible.

Die Drückmulde 7 ist in der vertikalen Vorderwand der Kappe 2 angebracht. Ein im oberen Randbereich der Kappe 2 verbleibender Wulst 8 erleichert es, mit dem Finger eine nach oben gerichtete Kraft auf die Kappe auszuüben, um den Verschluss zu öffnen.The pressure trough 7 is mounted in the vertical front wall of the cap 2. A bead 8 remaining in the upper edge region of the cap 2 makes it easier to exert an upward force on the cap with the finger in order to open the closure.

Bei kleineren Verschlüssen kann das Entfernen des Garantiebandes 4 relativ problematisch sein, weil es sich schlecht fassen lässt. Die Figuren 6 bis 8 zeigen eine Lösung dieses Problems. In der Kappe 2 ist seitlich eine gewölbte Vertiefung als Griffmulde 9 eingelassen, die in die Oberfläche der Kappe 2 ausläuft. Durch seine seitliche Anordnung wird die Griffmulde 9 durch das Garantieband 4 nur teilweise verdeckt (Figur 7). Die Griffmulde 9, die von oben deutlich erkennbar ist (Figur 8), erlaubt das Hintergreifen des Garantiebandes mit einem Finger, so dass es sich leicht abreissen lässt. Auch die nach aussen geneigte Vertiefung 9 bewirkt, dass das Garantieband 4 nach unten radial abgezogen wird. Die Verbindungsstege 6 zwischen dem Garantieband 4 und dem Unterteil 1 sind nur in der Ansicht von oben erkennbar.With smaller closures, the removal of the guarantee tape 4 can be relatively problematic because it is difficult to grasp. Figures 6 to 8 show a solution to this problem. In the cap 2 there is a curved recess on the side as a recessed grip 9, which runs out into the surface of the cap 2. Due to its lateral arrangement, the recessed grip 9 is only partially covered by the guarantee tape 4 (FIG. 7). The recessed grip 9, which can be clearly seen from above (FIG. 8), allows the guarantee band to be gripped behind with one finger, so that it is easy to tear off. The outwardly inclined recess 9 also causes the guarantee band 4 to be pulled off radially downward. The connecting webs 6 between the guarantee tape 4 and the lower part 1 can only be seen in the view from above.

Schliesslich sei noch vermerkt, dass die Verbindung zwischen Garantieband und Kappe nicht nur durch Stege erfolgen kann. Die Verbindung kann auch entlang der gesamten Verbindungslinie erfolgen und entsprechend geschwächt werden durch Sollbruchstellen oder Perforationen.Finally, it should be noted that the connection between the guarantee band and cap can not only be made by webs. The connection can also be made along the entire connection line and weakened accordingly by predetermined breaking points or perforations.
