Abstract

The closure for a threaded mouth (1) has a cap (10) made of plastic which is provided by means of tear-off elements (18) with a ring (12). If the ring is still on the cap (10) when the mouth is closed, it indicates that it has not yet been opened. By means of blocking elements (33), the ring (12) is blocked on the mouth against being unscrewed. The ring (12) has at least one opening (26), in which a carrier (30) of the cap (10) engages. When the cap is unscrewed, the carrier destroys the ring (12). This can be facilitated in that intended break points (21) are provided which have the form of narrow connection webs (20) between parts of the ring (12). <IMAGE>

Description

Stand der Technik, Aufgabe, LösungState of the art, task, solution

Die Erfindung bezieht sich auf einen Originalitätsverschluß mit den im Oberbegriff von Anspruch 1 genannten Merkmalen.The invention relates to a tamper-evident closure with the features mentioned in the preamble of claim 1.

Bei einem vorbekannten Originalitätsverschluß dieser Art, der von der Anmelderin hergestellt wird, läßt sich die Schraubkappe mit dem daran hängenden Ring auf die Mündung einer Flasche schrauben, wobei federnde Sperrelemente am Ring über entsprechende Sperrele­mente an der Flaschenmündung schnappen. Die Federelemente des Ringes sind, in Zuschraubrichtung betrachtet, schräg nach hinten gerichtet und wirken wie Klinken, die ein Zuschrauben gestatten, aber beim Abschrauben hinter die Sperrelemente der Mündung grei­fen und somit eine Rückdrehung des Ringes verhindern. Bei weite­rer Rückdrehung der Kappe werden dann die Abreißelemente von der Kappe abgerissen.In a previously known tamper-evident closure of this type, which is manufactured by the applicant, the screw cap with the ring attached to it can be screwed onto the mouth of a bottle, resilient locking elements on the ring snapping over corresponding locking elements on the bottle mouth. The spring elements of the ring, viewed in the screwing direction, are directed obliquely backwards and act like pawls that allow screwing, but reach behind the locking elements of the mouth when unscrewing and thus prevent the ring from turning back. When the cap is turned back further, the tear-off elements are then torn off the cap.

Nachteilig ist hierbei, daß der Ring auf der Mündung verbleibt. Im Schließzustand macht er daher nicht ausreichend deutlich, daß die Kappe schon einmal abgeschraubt worden ist. Außerdem besteht die Gefahr, daß der Ring beim Entleeren des Behälters oder der Flasche abfällt und z. B. in das ausgegossene Füllgut fällt.The disadvantage here is that the ring remains on the mouth. In the closed state, it therefore does not make it sufficiently clear that the cap has already been unscrewed. There is also a risk that the ring will fall off when emptying the container or bottle and z. B. falls into the poured filling.

Durch die vorliegende Erfindung soll ein Originalitätsverschluß der genannten Art dahingehend verbessert werden, daß der Ring beim ersten Öffnen der Kappe in Einzelteile zerlegt wird. Ande­rerseits muß der Ring aber so fest zusammenhalten, daß er nicht schon beim Zuschrauben beschädigt wird.The present invention is intended to improve a tamper-evident closure of the type mentioned in such a way that the ring is broken down into individual parts when the cap is first opened. On the other hand, the ring must hold together so tightly that it is not damaged when it is screwed on.

Diese Aufgabe wird nach Anspruch 1 gelöst.This object is achieved according to claim 1.

Der Mitnehmer der Kappe, der hiernach in eine Öffnung des Ringes eingreift, kann so stabil ausgeführt werden, daß er den Ring zerstört, wobei vorauszusetzen ist, daß der Ring aus einem Mate­rial besteht, das sein Zerreißen oder Zerbrechen zuläßt.The driver of the cap, which then engages in an opening of the ring, can be made so stable that it destroys the ring, provided that the ring is made of a material that allows it to tear or break.

Der Ring fällt, da er zerstört wird, beim ersten Öffnen von der Mündung ab, macht das Öffnen dadurch kenntlich und kann nicht beim Ausgießen in das Füllgut fallen.As it is destroyed, the ring falls off the mouth when it is opened for the first time, thereby identifying the opening and cannot fall into the filling material when pouring.

Weiterbildungen der ErfindungDevelopments of the invention

Nach Anspruch 2 kann der Ring Sollbruchstellen haben, die seine Zerstörung erleichtern. Dies ist dann wichtig, wenn der Ring wie die gesamte Kappe aus elastischem Kunststoff besteht, was mit Rücksicht auf Dichtungselemente und die federnden Sperrelemente von Vorteil ist.According to claim 2, the ring can have predetermined breaking points that facilitate its destruction. This is important if the ring, like the entire cap, is made of elastic plastic, which is advantageous with regard to sealing elements and the resilient locking elements.

Nach Anspruch 3 werden zweckmäßigerweise die Sollbruchstellen neben den Öffnungen für die Mitnehmer angeordnet. Die von den Mitnehmern ausgeübten Zugwirkungen in Umfangsrichtung wirken sich infolgedessen unmittelbar an den Sollbruchstellen aus.According to claim 3, the predetermined breaking points are advantageously arranged next to the openings for the driver. The tensile effects exerted by the drivers in the circumferential direction consequently have an immediate effect at the predetermined breaking points.

Nach Anspruch 6 können die Öffnungen die Mitnehmer mit Spiel umgeben, was inbesondere in Umfangsrichtung wichtig ist. Dadurch wird sichergestellt, daß die Mitnehmer beim Zuschrauben keine Kräfte auf den Ring übertragen, ihn also nicht zerstören können. Beim Abschrauben der Kappe treten zunächst die Sperrelemente in Funktion, die ein Abdrehen des Ringes verhindern. Anschließend werden die Abreißelemente zwischen Ring und Kappe durchgerissen. Danach können sich die Mitnehmer frei in ihren Öffnungen bewegen, so daß sie nach Aufbrauch des Spiels in Umfangsrichtung Kräfte auf Teile des Ringes übertragen und diesen an den Sollbruchstel­len zerreißen.According to claim 6, the openings can surround the driver with play, which is particularly important in the circumferential direction. This ensures that the drivers do not transmit any forces to the ring when it is screwed on, ie they cannot destroy it. When the cap is unscrewed, the locking elements, which prevent the ring from being twisted off, come into operation. The tear-off elements between the ring and cap are then torn. Thereafter, the drivers can move freely in their openings so that they exert forces in the circumferential direction after the game has been used up transfer to parts of the ring and tear it at the predetermined breaking points.

Nach Anspruch 7 erhält der Mitnehmer eine Form, die eine einfache Herstellung der Kappe im Spritzverfahren ermöglicht.According to claim 7, the driver receives a shape that enables easy manufacture of the cap by spraying.

Figur 4 und 5 zeigen eine Mündung einer Glasflasche. Die Mündung 1 hat ein Schraubgewinde 2 für eine Verschlußkappe. Unterhalb des Schraubgewindes hat die Mündung an einer Verdickung vier Sperre­lemente 3 in Form von Nocken mit je einer auswärts gekrümmten Auflauffläche 5, die im Uhrzeigersinne ansteigt und einer Sperr­fläche 7, die in einer Radialebene verläuft.Figures 4 and 5 show a mouth of a glass bottle. The mouth 1 has a screw thread 2 for a closure cap. Below the screw thread, the mouth of a thickening has four locking elements 3 in the form of cams, each with an outwardly curved ramp surface 5 that rises in the clockwise direction and a locking surface 7 that extends in a radial plane.

Figur 1 und 2 zeigen die zugehörige Schraubkappe 10 (im folgenden nur "Kappe" genannt), die zur Originalitätssicherung einen Ring 12 trägt. Kappe und Ring können aus Polyäthylen oder Polypropylen gespritzt werden. Die Kappe hat ein Innengewinde 14, einen Dicht­ring 16 und einen Zentrierstutzen 17. Die Kappe ist mit dem Ring 12 durch vier Abreißelemente 18 verbunden. Die Abreißelemente haben die etwaige Form von Pyramidenstümpfen, deren Basen in den Ring übergehen und deren obere Enden in die Kappe übergehen.Figures 1 and 2 show the associated screw cap 10 (hereinafter only called "cap"), which carries a ring 12 for tamper-evident. The cap and ring can be molded from polyethylene or polypropylene. The cap has an internal thread 14, a sealing ring 16 and a centering socket 17. The cap is connected to the ring 12 by four tear-off elements 18. The tear-off elements have the possible shape of truncated pyramids, the bases of which in the Pass over the ring and its upper ends go into the cap.

Der Ring besteht aus zwei Segmenten (annähernd Hälften), die rechts und links nur durch je zwei dünne Verbindungsstege 20 miteinander verbunden sind. Hierdurch werden Sollbruchstellen 21 zwischen den beiden Ringsegmenten gebildet. Die Ringsegmente haben je einen Mantel 22 und oben einen Innenflansch 24. Der Innenflansch jedes Ringsegments ist in Umfangsrichtung kürzer als der Mantel, derart, daß sich rechts und links in Figur 2 je eine Öffnung 26 ergibt, die sich an der Stoßstelle zwischen beiden Ringsegmenten befindet und die der Sollbruchstelle 21 benachbart ist. Jeder Innenflansch 24 hat an seinem einen Ende eine nach unten ragende Rippe 27.The ring consists of two segments (approximately halves), which are connected on the right and left only by two thin connecting webs 20. As a result, predetermined breaking points 21 are formed between the two ring segments. The ring segments each have a jacket 22 and an inner flange 24 at the top. The inner flange of each ring segment is shorter in the circumferential direction than the jacket, such that there is an opening 26 on the right and left in FIG. 2, which is located at the joint between the two ring segments and which is adjacent to the predetermined breaking point 21. Each inner flange 24 has a downwardly projecting rib 27 at one end.

Der Mantel 28 der Kappe hat an einander gegenüberliegenden Stel­len je einen Mitnehmer 30 in Form eines etwa achsparallelen Fortsatzes, der in eine der Öffnungen 26 des Ringes ragt, und zwar mit Spiel sowohl in Umfangsrichtung gegenüber den Innenflan­schen 24 wie auch radial gegenüber den Mänteln 22 des Ringes. Der Mitnehmer hat die Aufgabe, beim Abschrauben der Kappe den Ring zu zerstören.The jacket 28 of the cap has at each opposite point a driver 30 in the form of an approximately axially parallel extension, which projects into one of the openings 26 of the ring, with play both in the circumferential direction with respect to the inner flanges 24 and radially with respect to the jackets 22 of the Ring. The driver has the task of destroying the ring when unscrewing the cap.

Am Mantel 22 des Ringes sitzen vier schräg einwärts ragende Sperrelemente 33. Sie verlaufen unter etwa 45° schräg zu einer Radialebene. Sie wirken mit den Sperrelementen 3 der Mündung zusammen. Die ganze Kappe einschließlich des Ringes und der Sperrelemente besteht aus elastischem Kunststoff.Four locking elements 33 projecting obliquely inwards sit on the jacket 22 of the ring. They run at an angle of approximately 45 ° to a radial plane. They interact with the locking elements 3 of the mouth. The entire cap including the ring and the locking elements is made of elastic plastic.

Funktionfunction

Beim Zuschrauben der Mündung geraten schließlich die Sperrelemen­te 33 des Ringes in den Bereich der Sperrelemente 3 der Mündung. Sie führen eine Ratschenbewegung aus, laufen also an den Flächen 5 jeweils auswärts und springen nach dem Überqueren jedes Sperr­elementes wieder einwärts. Die Verbindungsstege 20 sind ausrei­ chend stark dimensioniert, so daß der Ring beim Zuschrauben diesen Belastungen standhält.When the mouth is screwed on, the locking elements 33 of the ring finally end up in the area of the locking elements 3 of the mouth. They perform a ratchet movement, so they run outwards on the surfaces 5 and jump inwards after crossing each locking element. The connecting webs 20 are sufficient chend strongly dimensioned so that the ring withstands these loads when screwing.

Beim Abschrauben läßt sich die Kappe zunächst so weit zurückdre­hen, bis die Sperrelemente mit ihren freien Enden an die Sperr­flächen 7 stoßen. Damit wird eine Weiterdrehung des Ringes blockiert. Wird die Kappe weitergedreht, so reißen die Abreißelemente 18 durch. Beim Weiterdrehen der Kappe bewegen sich die Mitnehmer 30 der Kappe in den Öffnungen 26 des Ringes in Umfangsrichtung und berühren dann die Rippen 27 der Innenflansche 24, während der Ring stehen bleibt. Beim Weiterdrehen mit dem nötigen Kraftauf­wand werden die Verbindungsstege 20 durchgerissen, und zwar an beiden aneinander gegenüberliegenden Sollbruchstellen 21. Der Ring wird damit in zwei Hälften unterteilt, die dann herabfallen.When unscrewing, the cap can first be turned back until the blocking elements hit the blocking surfaces 7 with their free ends. This prevents further rotation of the ring. If the cap is turned further, the tear-off elements 18 tear through. When the cap is turned further, the catches 30 of the cap move in the openings 26 of the ring in the circumferential direction and then touch the ribs 27 of the inner flanges 24 while the ring remains standing. When turning further with the necessary effort, the connecting webs 20 are torn through, specifically at both opposing predetermined breaking points 21. The ring is thus divided into two halves, which then fall down.

Variantenvariants

Der Ring kann durch Sollbruchstellen in mehr als zwei Segmente unterteilt sein, was eine entsprechende Anzahl von Mitnehmern 30 bedingt. Die Sollbruchstellen können anders ausgebildet sein als dargestellt. Z. B. genügt eine Schwächung des Ringmantels 22. Oder es können je Sollbruchstelle mehr als zwei Verbindungsstege oder nur einer vorgesehen sein. Die Mündung sollte mindestens zwei Sperrelemente 3 haben. Der Ring sollte mindestens zwei, kann aber auch mehr als vier Sperrelemente 33 haben.The ring can be divided into more than two segments by predetermined breaking points, which requires a corresponding number of drivers 30. The predetermined breaking points can be designed differently than shown. For example, a weakening of the ring jacket 22 is sufficient. Or more than two connecting webs or only one can be provided for each predetermined breaking point. The mouth should have at least two locking elements 3. The ring should have at least two, but can also have more than four locking elements 33.
