- Original closures for containers consist of a screw cap and a plastic locking ring that can be destroyed during the first unscrewing process, whereby the screw cap and locking ring consist of separate units.
- locking rings The purpose of such locking rings is to indicate the unauthorized opening of the screw cap for the purpose of removing the contents of the container.
- predetermined breaking points are arranged over the circumference of the locking ring, which are broken open at the same time when the screw cap is screwed on.
- predetermined breaking points distributed over the locking ring are broken open, however, there is so much play that the locking ring can expand sufficiently without the individual ring parts really jumping off.
- the connection of the locking ring is retained, so that the connected ring parts can be compressed after reclosure . This largely obscures the reliable identification of an unauthorized container opening.
- the blasting force is concentrated only on two predetermined breaking points.
- the ring has no other alternatives. Since the predetermined breaking points are opened one after the other, the blasting section is released from the ring structure and is ejected as a whole. It is no longer possible to join the individual ring parts.
- the disadvantage here is the intricate structure of the very flat retaining ring, which can break unintentionally during rough filling operations if the canister nozzle is not carefully placed and the screw cap is subsequently screwed on. Even when the operator grips the ring with gloved and therefore comparatively numb hands, broken rings cannot be ruled out. Since the locking ring is still transported via the screw cap when it is closed and locked using special tongues that are flexible in the direction of rotation but fixed in the direction of rotation and abut against stop cams, the sensitive tongues can be torn off when the screw cap is screwed on and if the ring position is not precisely adjusted without being visible from the outside.

Abstract
Bei einem Originalverschluß für Behälter besteht die Originalitätssicherung aus einer Siegelkappe (1), die auf die Schraubkappe (6) aufgesteckt wird und auf dieser in Achsrichtung unverrückbar einrastet. Am unteren Rand der Siegelkappe (1) ist ein Sicherungsring einstückig angeformt, der aus einem feststehenden Teil (2) und einer Absprengsektion (5) besteht. Die Absprengsektion (5) ist durch Einschnittsausnehmungen (3 und 4) vom feststehenden Teil (2) getrennt und über Abreißstege (8) mit dem Außenmantel der Kappe (1) verbunden. Am Kanister befindet sich ein Steg (9), der in den Raum der Einschnittsausnehmung (3) hineinragt und hierdurch einen Verdrehanschlag bildet. Auf der der Einschnittsausnehmung (3) gegenüberliegenden Seite des Sicherungsringes ist eine durch Schwächungskerben (13) begrenzte Aufreißlasche (10) angeordnet.In the case of an original closure for containers, the tamper-evident device consists of a sealing cap (1) which is placed on the screw cap (6) and snaps firmly into place in the axial direction. At the lower edge of the sealing cap (1), a locking ring is integrally formed, which consists of a fixed part (2) and a blasting section (5). The chipping section (5) is separated from the fixed part (2) by cut-out recesses (3 and 4) and is connected to the outer jacket of the cap (1) via tear-off webs (8). There is a web (9) on the canister which projects into the space of the incision recess (3) and thereby forms a twist stop. On the side of the retaining ring opposite the incision recess (3) there is a tear-open tab (10) limited by weakening notches (13).
Description
Originalverschlüsse für Behälter bestehen aus einer Schraubkappe und einem während des ersten Abschraubvorganges zerstörbaren Sicherungsring aus Kunststoff, wobei Schraubkappe und Sicherungsring aus getrennten Einheiten bestehen.Original closures for containers consist of a screw cap and a plastic locking ring that can be destroyed during the first unscrewing process, whereby the screw cap and locking ring consist of separate units.
Aufgabe derartiger Sicherungsringe ist es, das unberechtigte öffnen der Schraubkappe zwecks Entnahme des Behälterinhaltes kenntlich zu machen. Zu diesem Zweck sind über den Umfang des Sicherungsringes gleichmäßig verteilte Sollbruchstellen angeordnet, die beim Aufschrauben der Schraubkappe zu gleicher Zeit aufgebrochen werden. Beim gleichzeitigen Aufbrechen mehrerer über den Sicherungsring verteilter Sollbruchstellen entsteht jedoch so viel Spiel, daß sich der Sicherungsring genügend aufweiten kann, ohne daß die einzelnen Ringteile wirklich abspringen.. Der Verband des Sicherungsringes bleibt erhalten, so daß die zusammenhängenden Ringteile nach dem Wiederverschluß zusammengedrückt werden können. Eine sichere Kenntlichmachung einer unberechtigten Behälteröffnung ist hierdurch weitgehend verwischt.The purpose of such locking rings is to indicate the unauthorized opening of the screw cap for the purpose of removing the contents of the container. For this purpose, evenly distributed predetermined breaking points are arranged over the circumference of the locking ring, which are broken open at the same time when the screw cap is screwed on. When several predetermined breaking points distributed over the locking ring are broken open, however, there is so much play that the locking ring can expand sufficiently without the individual ring parts really jumping off. The connection of the locking ring is retained, so that the connected ring parts can be compressed after reclosure . This largely obscures the reliable identification of an unauthorized container opening.
Deswegen ist man gemäß Offenlegungsschrift 26 07 991 dazu übergegangen, einen Originalverschluß zu schaffen, mit dem ein Absprengen nur eines Ringteiles beim Abschrauben der Schraubkappe mit Sicherheit eintritt, ohne daß die Möglichkeit besteht, durch Zusammendrücken der aufgebrochenen Ringteile einen Originalverschluß vorzutäuschen.For this reason, according to laid-open specification 26 07 991, it has gone over to creating an original closure with which only one ring part comes off when the screw cap is unscrewed, without the possibility of simulating an original closure by compressing the broken ring parts.
Da nur eine einzige Absprengsektion vorgesehen ist und der übrige Ringteil in sich geschlossen bleibt, wird die Absprengkraft nur auf zwei Sollbruchstellen konzentriert. Der Ring hat keine anderen Ausweichmöglichkeiten. Da das Öffnen der Sollbruchstellen nacheinander erfolgt, löst sich die Absprengsektion aus dem Ringverband und wird als Ganzes ausgeworfen. Ein Zusammenfügen der einzelnen Ringteile ist nicht mehr möglich.Since only a single blasting section is provided and the rest of the ring part remains closed, the blasting force is concentrated only on two predetermined breaking points. The ring has no other alternatives. Since the predetermined breaking points are opened one after the other, the blasting section is released from the ring structure and is ejected as a whole. It is no longer possible to join the individual ring parts.
Nachteilig hierbei ist jedoch der verwickelte Aufbau des sehr flach gehaltenen Sicherungsringes, der beim rauhen Abfüllbetrieb bei nicht sorgfältigem Aufsetzen auf den Kanisterstutzen und nachfolgendem Aufschrauben der Schraubkappe ungewollt brechen kann. Schon beim Ergreifen des Ringes mit behandschuhten und damit vergleichsweise gefühllosen Händen des Bedienungsmannes sind Ringbrüche nicht auszuschließen. Da weiterhin der Sicherungsring über die Schraubkappe beim Zudrehen in die Rastlage transportiert wird und über besondere, in Zudrehrichtung nachgiebige, jedoch in Aufdrehrichtung feststehende und gegen Anschlagnocken anliegende Zungen verdrehfest gehalten wird, können die empfindlichen Zungen beim Zuschrauben der Schraubkappe und bei nicht genau justierter Ringlage abgerissen werden, ohne daß dies von außen sichtbar wird. Damit hat der Sicherungsring seine Funktion verloren.The disadvantage here, however, is the intricate structure of the very flat retaining ring, which can break unintentionally during rough filling operations if the canister nozzle is not carefully placed and the screw cap is subsequently screwed on. Even when the operator grips the ring with gloved and therefore comparatively numb hands, broken rings cannot be ruled out. Since the locking ring is still transported via the screw cap when it is closed and locked using special tongues that are flexible in the direction of rotation but fixed in the direction of rotation and abut against stop cams, the sensitive tongues can be torn off when the screw cap is screwed on and if the ring position is not precisely adjusted without being visible from the outside. The circlip has lost its function.
Die Erfindung geht ebenfalls aus von einem Originalverschluß für Behälter, bestehend aus einer Schraubkappe und einem bei unberechtigtem Öffnen zestörbaren Sicherungsring aus Kunststoff, wobei Schraubkappe und Sicherungsring aus getrennten Einheiten bestehen, und der Sicherungsring eine einzige Absprengsektion aufweist.The invention is also based on an original closure for containers, consisting of a screw cap and a plastic locking ring which can be destroyed when opened without authorization, the screw cap and locking ring being used consist of separate units, and the locking ring has a single blasting section.
Es handelt sich um die Aufgabe, einen solchen Originalverschluß so zu gestalten, daß der Sicherungsring nicht mehr über die Schraubkappenverdrehung in seine Arbeitsstellung transportiert wird. Der Ringaufbau soll wesentlich vereinfacht und robuster gestaltet werden und auch die Justierung und Handhabung des Ringes soll weitgehend verbessert werden.It is the task of designing such an original closure in such a way that the locking ring is no longer transported into its working position by twisting the screw cap. The ring structure should be simplified and made more robust and the adjustment and handling of the ring should be largely improved.
Diese Aufgaben werden erfindungsgemäß dadurch gelöst, daß der Sicherungsring und die von diesem durch Einschnittsausnehmungen getrennte Absprengsektion am unteren Teil des Außenmantels einer im aufgeschraubten Zustand der Schraubkappe auf diese aufgesetzten und mittels am unteren Innenrand angeformten Rastlippen den Schraubkappenunterrand untergreifenden Siegelkappe einstückig angeformt sind, wobei die Absprengsektion über Abreißstege mit dem Kappenaußenmantel verbunden ist und mit einer der Einschnittsausnehmungen zwischen feststehendem Ringteil und Absprengsektion im aufgesetzten Zustand der Siegelkappe einen am Kanister vorgesehenen Steg verdrehfest übergreift, und daß an der dieser Einschnittsausnehmung gegenüberliegenden Kappenseite eine durch Schwächungskerben begrenzte Aufreißlasche angeordnet ist.These objects are achieved according to the invention in that the securing ring and the detachment section separated from it by incision recesses are integrally formed on the lower part of the outer casing of a sealing cap which is placed on the screw cap in the screwed-on state of the screw cap and is formed on the lower inner edge by means of locking lips which form underneath the screw cap underside, the detaching section is connected to the outer shell of the cap by means of tear-off webs and, with one of the cut-out recesses between the fixed ring part and the detachment section in the fitted state of the sealing cap, rotatably engages over a web provided on the canister, and that a tear-open tab limited by weakening notches is arranged on the opposite side of the cut-out recess.
Dadurch, daß der Sicherungsring zu einer Siegelkappe erweitert ist, erleichtert sich wesentlich die Handhabung. Die Funktion des Sicherungsringes liegt außerhalb der Schraubkappe, die ihrerseits von der Siegelkappe umgeben wird.The fact that the retaining ring is expanded to form a sealing cap makes handling much easier. The function of the locking ring lies outside the screw cap, which in turn is surrounded by the sealing cap.
Nach dem Füllvorgang wird die Schraubkappe geschlossen und sodann die Siegelkappe mit dem Sicherungsring auf die Schraubkappe aufgeklemmt und mit den Rastlippen in senkrechter Richtung unverrückbar auf dieser gehalten. Dabei übergreift die der Aufreißlasche gegenüberstehende Einschnittsausnehmung den Kanistersteg. Die Einschnittsausnehmung ist vergleichsweise breit. gehalten, so daß ein besonderer Justierungsaufwand entfällt. Um die Siegelkappe zu entfernen, wird die Aufreißlasche abgezogen und damit eine Aufspaltung der Siegelkappe herbeigeführt.After the filling process, the screw cap is closed and then the sealing cap is clamped onto the screw cap with the retaining ring and held immovably on it with the locking lips in the vertical direction. The incision recess opposite the tear-open tab overlaps the canister web. The incision recess is comparatively wide. held so that a special adjustment effort is not necessary. In order to remove the sealing cap, the pull tab is pulled off, thus causing the sealing cap to split.
Versucht ein Unbefugter mittels einer an die Siegelkappe angesetzten Rohrzange die Schraubkappe zu öffnen, schlägt die Absprengsektion gegen den Kanistersteg und reißt ab, wodurch die unbefugte Öffnung kenntlich gemacht wird.If an unauthorized person tries to open the screw cap using a pipe wrench attached to the sealing cap, the blasting section hits the canister web and tears off, which indicates the unauthorized opening.
Um zu verhindern, daß ein Hebelwerkzeug zwischen den feststehenden Teil des Sicherungsringes und der Kanisterwand eingesetzt wird, um die Siegelkappe in senkrechter Richtung aus seiner Rastlage abzuhebeln, ist nach einem weiteren Gedanken der Erfindung die Außenwand des Sicherungsringes und der Absprengsektion über den inneren Rastrand der Siegelkappe vorgezogen und im aufgesetzten Kappenzustand bis an die Kanisterwand herangeführt.In order to prevent a lever tool from being inserted between the fixed part of the locking ring and the canister wall in order to pry the sealing cap out of its locking position in a vertical direction, the outer wall of the locking ring and the blasting section is, according to a further idea of the invention, over the inner locking edge of the sealing cap brought forward and brought up to the canister wall in the cap state.
Zur weiteren Sicherung gegen Aufhebeln sind im Außenmantel des feststehenden Teils des Sicherungsringes senkrechte Schwächungskerben angeordnet, die bei Gewaltanwendung aufreißen.To further secure against prying open vertical weakening notches are arranged in the outer jacket of the fixed part of the locking ring, which tear open when force is used.
