Abstract

A safety band (3) of a sealing unit (1) has two retaining noses (12a, 12b; 13a, 13b) arranged in diagonally facing pairs. The retaining noses (12a, 12b; 13a, 13b) standing out on the clear opening of the safety band (3) are axially displaced. When the bottle (17) is closed, the pair of retaining noses (12a, 12b) is first split and then glides on the retaining rib (15). After that the retaining noses (13a, 13b) that are displaced 90° are split and also glide beneath the retaining rib (15). When the bottle is opened the retaining noses (13a, 13b) are first retained on the retaining rib (15) and the connecting webs (9) to the screw-type cap (2) are broken. Afterwards, the remaining webs (9) are also broken once the axially offset retaining noses (12a, 12b) are obstructed by the retaining rib (15).

Description

Schraubverschluss mit einem Sicherheits- und GarantiebandScrew cap with a security and guarantee band
Die Erfindung betrifft einen Schraubverschluss mit einem Sicherheitsund Garantieband für Raschen.The invention relates to a screw cap with a security and guarantee tape for rapid.
Sicherheits- und Garantiebänder sind heute an den meisten Schraubverschlüssen ausgebildet, um das erste Öffnen der Flasche anzuzeigen und um zu verhindern, dass durch Unbefugte, der Inhalt der Flascbe kontaminiert werden kann. Die Sicherheitsbänder bestehen aus einem zylindermantelförmigen Abschnitt, der durch Verbindungsstege mit der Unterkante des Mantels des Schraubverschlusses verbunden ist. Die Bänder können an ihrem Umfang Schwächungsbereiche aufweisen, welche beim erstmaligen Öffnen reissen. Die Bandabschnitte bleiben mit dem Schraubverschluss verbunden. Sie können aber auch einstückig hergestellt sein und verbleiben nach dem erstmaligen Öffnen unterhalb einer Rückhalterippe, die sich axial unterhalb des Gewindes am Raschenhals befindet. Bei den herkömmlichen Sicherheits- und Garantiebändern sind entweder an der Unterkante derselben oder an deren Innenfläche über den Umfang verteilt und in den lichten Querschnitt ragende Vielzahl, über den Umfang verteilt angeordnete Rückhaltenocken ausgebildet. Diese Rückhaltenocken gleiten beim Aufschrauben des Deckels beim Abfüller der Flasche über die Rückhalterippe und rasten unter derselben ein. Beim Öffnen des Schraubverschlusses wird das Sicherheitsband von den Rückhaltenocken, die oben eine Rückhaltefläche aufweisen, zurückgehalten und die Verbindungsstege zwischen dem Schraubverschluss und dem Sicherheitsband brechen. Beim Aufschrauben oder Aufdeckeln des Schraubverschlusses beim Abfüller der Flasche können durch den Widerstand, der beim Passieren der Nocken über die Rückhalterippe auftritt, Probleme entstehen, und das Sicherheitsband kann, wenn es schräg gestellt wird, zwischen den Flaschenhals und den Mantel des Schraubverschlusses gedrückt und verklemmt werden. Das Sicherheitsband oder die Verbindungsstege zum Verschluss können bereits beim Schliessvorgang reissen. Das Sicherheitsband verliert dabei seinen Zweck. Bei Hochleistungsabfüllanlagen kann ein Defekt der genannten Art zum Stillstand der gesamten Anlage führen. Aber auch beim Öffnen der Schraubdeckel reissen die bekannten Sicherheitsbänder häufig nur einseitig oder werden teilweise über die Rückhalterippe hinausgezogen. Beim Wiederverschliessen verklemmt sich das Sicherheitsband zwischen Flaschenhals und dem Mantel des Schraubverschlusses, so dass ein dichter Wiederverschluss nicht möglich ist, wenn nicht zuvor das Sicherheitsband von Hand entfernt oder zurückgeschoben wird.Safety and guarantee tapes are formed on most screw caps today to indicate the first opening of the bottle and to prevent unauthorized persons from contaminating the contents of the bottle. The security tapes consist of a section in the shape of a cylinder jacket, which is connected to the lower edge of the jacket of the screw closure by connecting webs. The bands can have weakening areas on their circumference, which tear when they are opened for the first time. The band sections remain connected with the screw cap. But they can also be made in one piece and remain after opening for the first time below a retaining rib, which is located axially below the thread on the snap neck. In the conventional security and guarantee tapes are distributed either on the lower edge of the same or on its inner surface over the circumference and protruding in the clear cross section, over the circumferentially arranged retaining cams are formed. These retention cams slide over the retention rib when the bottle is being screwed on and engage under it. When the screw cap is opened, the safety strap is held back by the retaining cams, which have a retaining surface at the top, and the connecting webs between the screw cap and the safety strap break. When screwing on or uncovering the screw cap on the bottle filler, problems can arise due to the resistance that occurs when passing the cams via the retaining rib, and the security band, if it is tilted, can be pressed and jammed between the bottle neck and the jacket of the screw cap become. The safety band or the connecting bars for the closure can tear during the closing process. The security band loses its purpose. In high-performance filling systems, a defect of the type mentioned can lead to the entire system coming to a standstill. But even when the screw cap is opened, the known security tapes often tear only on one side or are partially pulled out over the retaining rib. When reclosing, the safety band is jammed between the bottle neck and the jacket of the screw cap, so that a tight reclosure is not possible unless the safety band is first removed or pushed back by hand.
Der hier vorliegenden Erfindung lag die Aufgabe zugrunde, ein Sicherheitsband zu schaffen, das beim Abfüller auf Hochleistungsabfüllmaschinen störungsfrei auf die Flasche aufgebracht werden kann und das beim Öffnen der Flasche durch den Konsumenten sich einwandfrei vom Schraubverschluss trennt und unterhalb der Rückhalterippe auf dem Flaschenhals zurückbleibt oder bei Mehrwegflaschen reisst und mit dem Schraubverschluss verbunden bleibt. Gelöst wird diese Aufgabe durch ein Sicherheits- und Garantieband gemass den Merkmalen des Patentanspruches 1.The object of the present invention was to create a safety band which can be applied to the bottle without problems on the bottler on high-performance filling machines and which, when the bottle is opened by the consumer, is properly separated from the screw cap and remains on the bottle neck below the retaining rib or at Reusable bottles tear and remain connected with the screw cap. This object is achieved by a security and guarantee tape according to the features of claim 1.
Die axial versetzt angeordneten Rückhaltenocken bewirken beim Aufdeckeln wesentlich geringere Spreizkräfte auf das Sicherheitsband und verhindern dessen vorzeitige Zerstörung.The axially staggered retaining cams cause considerably lower spreading forces on the safety belt when it is being unrolled and prevent its premature destruction.
Zwei paarweise und axial versetzt zueinander angeordnete Rückhaltenocken gleiten beim Aufschrauben des Schraubdeckels ebenfalls nacheinander über die Rückhalterippe, wodurch das Sicherheitsband, wegen der ovalen Verformung kaum gedehnt wird und eine geringe axiale Anpresskraft notwendig ist, um das Überspringen der Rückhalterippe zu ermöglichen. Beim Öffnen der Flasche werden vorerst die beiden obenliegenden Haltenocken von der Rückhalterippe zurückgehalten, und es treten nur dort Zugkräfte auf die Verbindungsstege auf, die vorzugsweise seitlich der Rückhaltenocken ausgebildet sind und reissen diese durch. Sobald die ersten Verbindungsstege gerissen sind gelangen die nächsten Rückhaltenocken an die Rückhalterippe und reissen die benachbarten Verbindungsstege durch. Eine Schrägstellung des Sicherheitsbandes wird dadurch vermieden, und es bleibt, falls einteilig ausgebildet, stets unterhalb der Rückhalterippe auf dem Flaschenhals zurück. Ein Sicherheitsband mit Sollbruchstelle und Anbindung an den Schraubverschluss bleibt an letzterem hängen.Two retaining cams arranged in pairs and axially offset from one another also slide one after the other over the retaining rib when the screw cap is screwed on, as a result of which the safety band, due to the oval deformation, is hardly stretched and a small axial contact force is necessary to enable the retaining rib to jump over. When the bottle is opened, the two retaining cams at the top are initially held back by the retaining rib, and tensile forces only occur there on the connecting webs, which are preferably formed on the side of the retaining cams, and tear them through. As soon as the first connecting webs are torn, the next retaining cams reach the retaining rib and tear through the neighboring connecting webs. This avoids an inclined position of the safety band and, if formed in one piece, it always remains on the bottle neck below the retaining rib. A security band with a predetermined breaking point and connection to the screw cap remains attached to the latter.

In den Figuren 1 und 2 ist mit Bezugszeichen 1 eine Verschlusseinheit bestehend aus einem Schraubverschluss 2 und einem Sicherheitsband 3 schematisch dargestellt. Die Verschlusseinheit 1 besteht aus thermoplastischem Kunststoff und wird durch Spritzen hergestellt. Der Schraubverschluss 2 umfasst einen Boden 4, an dem eine konzentrisch zur Symmetrie-Achse A verlaufende Dichtungsrippe 5 angebracht sein kann. An den Boden 4 schliesst ein Mantel 6 an, der auf seiner Innenseite vorzugsweise in Abschnitte aufgeteilte Gewindegänge 7 trägt. Die Ausbildung des Schraubverschlusses 2 ist allgemein bekannt und wird hier nicht näher erläutert. Das Sicherheits- und Garantieband 3 ist durch sehr dünne, wenige Zehntelsmillimeter dicke Stege 9 mit der Unterkante 8 des Mantels 6 des Schraubverschlusses 2 verbunden. Die Länge der Verbindungsstege 9 bzw. der Abstand zwischen der Oberkante 10 des Sicherheitsbandes ist sehr gering und liegt in der Grössenordnung von einigen Zehntelsmillimetern.In FIGS. 1 and 2, a closure unit consisting of a screw closure 2 and a security band 3 is shown schematically with reference number 1. The closure unit 1 is made of thermoplastic material and is produced by injection molding. The screw cap 2 comprises a base 4 on which a sealing rib 5 running concentrically to the axis of symmetry A can be attached. Connected to the bottom 4 is a jacket 6, which preferably has thread turns 7 which are divided into sections on its inside. The design of the screw cap 2 is generally known and is not explained in more detail here. The security and guarantee tape 3 is connected to the lower edge 8 of the jacket 6 of the screw cap 2 by means of very thin webs 9 which are a few tenths of a millimeter thick. The length of the connecting webs 9 or the distance between the upper edge 10 of the security band is very small and is of the order of a few tenths of a millimeter.
Auf der inneren Mantelfläche 11 des Sicherheitsbandes 3 sind im dargestellten Beispiel zwei Rückhaltenockenpaare 12a, 12b; 13a, 13b ausgebildet. Die Rückhalteπocken 12a und 12b sowie die Rückhaltenocken 13a und 13b liegen sich diagonal gegenüber, sind um ca. 90° versetzt und axial, d.h. bezüglich der axialen Ausdehnung des Sicherheitsbandes 3, um einen Betrag a gegeneinander versetzt. Die Rückhaltenocken 12a und 12b liegen folglich um den Betrag a näher an der Unterkante 14 des Sicherheitsbandes 3 als die Rückhaltenocken 13a und 13b. Der Abstand a ist vorzugsweise kleiner als die Höhe b einer umlaufenden RückhalterippeIn the example shown, two pairs of retaining cams 12a, 12b; 13a, 13b educated. The retaining cams 12a and 12b and the retaining cams 13a and 13b are located diagonally opposite one another, are offset by approximately 90 ° and are offset axially, ie with respect to the axial extent of the security band 3, by an amount a. The retention cams 12a and 12b are consequently closer to the lower edge 14 of the security band 3 than the retention cams 13a and 13b by the amount a. The distance a is preferably less than the height b of a circumferential retaining rib

16 der Flasche 17 sind vom Flaschenhals 16 nach aussen ragende Gewindeabschnitte 18 sichtbar, welche mit den entsprechenden Gewindeabschnitten 7 auf der Innenseite des Mantels 6 des Schraubverschlusses 2 in Eingriff zu gelangen bestimmt sind.16 of the bottle 17 are visible from the bottle neck 16 outwardly projecting threaded sections 18 which are intended to come into engagement with the corresponding threaded sections 7 on the inside of the jacket 6 of the screw cap 2.
Die Verbindungsstege 9 liegen, in Umfangsrichtung betrachtet, zwischen dem Rückhaltenocken 12a, 12b; 13a, 13b. Alternativ zu den Stegen 9 könnten auch filmartige Verbindungen den Schraubverschluss 2 und das Sicherheitsband 3 zusammenhalten.When viewed in the circumferential direction, the connecting webs 9 lie between the retaining cams 12a, 12b; 13a, 13b. As an alternative to the webs 9, film-like connections could also hold the screw cap 2 and the security band 3 together.
Die Funktionsweise des Sicherheitsbandes 3 des ersten Ausführungsbeispieles wird nachfolgend anhand der Figur 3 erklärt. Beim Verschliessen der Flasche 17 mit der Verschlusseinheit 1 wird letztere von oben axial auf den Flaschenhals 16 aufgesetzt und, von oben gesehen, im Uhrzeigersinn gedreht. Dabei gelangen vorerst die Gewindeabschnitte 7 am Schraubverschluss 2 in Eingriff mit den Gewindeabschnitten 18 am Flaschenhals 16. Nach ca. einer Umdrehung um 360° gelangen die angeschrägten Unterkanten 19 der Rückhaltenocken 12a und 12b in Kontakt mit der geneigten Oberkante der Rückhalterippe 15 am Flaschenhals 16. Beim Weiterdrehen und dadurch axialen Vorschub der Verschlusseinheit 1 werden die beiden Rückhaltenocken 12a und 12b radial nach aussen gedrückt und gleichzeitig die beiden um ca. 90° versetzten Rückhaltenocken 13a und 13b nach innen gezogen. Das Sicherheitsband 3 nimmt dabei eine ovale Gestalt an und dehnt sich nur äusserst wenig und höchstens innerhalb der Elastizitätsgrenze. Sobald die beiden Scheitel S! auf den Rückhaltenocken 12a und 12b sowie der Scheitel S2 auf der Rückhalterippe 15 übereinander hinweggegleitet sind, werden die beiden Rückhaltenocken 12a und 12b radial wieder nach innen gezogen, weil zu diesem Moment die beiden axial versetzt angeordneten Rückhaltenocken 13a und 13b nun auch in Kontakt mit der Rückhalterippe 15 gelangen und analog den beiden anderen Rippen radial nach aussen gedrängt werden. Dabei wird der Querschnitt des Sicherheitsbandes 3 wiederum oval. Schon nach kurzer Zeit gleiten auch die beiden Rückhaltenocken 13a und 13b über die Rückhalterippe 15 hinweg und befinden sich danach, wie auch die beiden Rückhaltenocken 12a und 12b, im zylindrischen Bereich 20 des Flaschenhalses 16. Beim Schliessen der Flasche 16 werden die dünnen Verbindungsstege 9 nur sehr wenig mechanisch beansprucht, weil durch den axialen Druck das Sicherheitsband 3 mit seiner Oberkante 10 an der Unterkante 8 des Mantels anliegt und die Verbindungsstege 9 dabei nur gestaucht werden.The functioning of the security band 3 of the first exemplary embodiment is explained below with reference to FIG. 3. When the bottle 17 is closed with the closure unit 1, the latter is placed axially from above onto the bottle neck 16 and, viewed from above, rotated clockwise. Initially, the threaded sections 7 on the screw cap 2 come into engagement with the threaded sections 18 on the bottle neck 16. After approximately one revolution through 360 °, the bevelled lower edges 19 of the retaining cams 12a and 12b come into contact with the inclined upper edge of the retaining rib 15 on the bottle neck 16. When the locking unit 1 is rotated further and thereby axially advanced, the two retaining cams 12a and 12b are pressed radially outward and at the same time the two retaining cams 13a and 13b, which are offset by approximately 90 °, are pulled inward. The security band 3 takes on an oval shape and stretches very little and at most within the elastic limit. As soon as the two vertices S ! on the retaining cams 12a and 12b and the apex S 2 on the retaining rib 15, the two retaining cams 12a and 12b are pulled radially inwards again, because at this moment the two axially offset retaining cams 13a and 13b are now also in contact with the retaining rib 15 arrive and are pushed radially outward analogously to the other two ribs. The cross section of the security band 3 in turn becomes oval. After a short time, the two retaining cams 13a and 13b also slide over the retaining rib 15 and are then, like the two retaining cams 12a and 12b, in the cylindrical region 20 of the bottle neck 16. When the bottle 16 is closed, the thin connecting webs 9 only become very little mechanically stressed because the axial pressure causes the safety band 3 with its upper edge 10 to rest against the lower edge 8 of the jacket and the connecting webs 9 are only compressed.
Beim Öffnen des Schraubverschlusses gelangen vorerst die beiden einander diagonal gegenüberliegenden Rückhaltenocken 13a und 13b in Kontakt mit der Rückhalterippe 15 am Flaschenhals 16. Da aber weder an den Rückhaitenocken 13a und 13b noch an der Rückhalterippe 15 geneigte Flächen aufeinandertreffen und ein Auseinanderschieben der beiden Teile wie beim Aufschrauben bzw. Verschliessen ermöglichen, sondern die Rückhalterippe 15 die Rückhaltenocken 13a und 13b nicht passieren lässt, werden letztere zurückgehalten und die seitlich der Rückhaltenocken 13a und 13b liegenden Verbindungsstege 9 entzweigerissen. Beim Weiterdrehen, beispielsweise um eine Viertels- oder Halbdrehung, gelangen dann auch die Rückhaltenocken 12a und 12b in Anlage an die Rückhalterippe 15. Wegen den bereits gerissenen Stegen 9 wird das Sicherheitsband 3 wieder oval verformt und zieht dabei die nun in Eingriff gelangenden Rückhaltenocken 12a, 12b unter die Rückhalterippe 15. Dabei werden die restlichen Verbindungsstege 9 gerissen. Das Sicherheitsband 3 verbleibt nun im Bereich 20 unterhalb der Rückhalterippe 15. Ohne das nun abgerissene Sicherheitsband 3 kann der Schraubverschluss 2 zum Wiederverschliessen der Flasche 17 auf deren Hals 16 aufgeschraubt werden.When the screw cap is opened, the two diagonally opposite retaining cams 13a and 13b initially come into contact with the retaining rib 15 on the bottle neck 16. However, since neither inclined surfaces meet on the retaining cams 13a and 13b nor on the retaining rib 15 and the two parts are pushed apart as in the case of Allow screwing or closing, but rather the retaining rib 15 does not allow the retaining cams 13a and 13b to pass, the latter are retained and the connecting webs 9 lying to the side of the retaining cams 13a and 13b are torn in two. When turning further, for example by a quarter or half turn, the retaining cams 12a and 12b then come into contact with the retaining rib 15. Because of the webs 9 which have already broken, the safety band 3 is again oval-shaped and thereby pulls those which are now engaged Retaining cams 12a, 12b under the retaining rib 15. The remaining connecting webs 9 are torn. The safety band 3 now remains in the area 20 below the retaining rib 15. Without the safety band 3 which has now been torn off, the screw cap 2 can be screwed onto the neck 16 of the bottle 17 in order to close it again.
Bei der Ausgestaltung der Erfindung nach den Figuren 5 und 6 ist das Sicherheitsband 3 im Bereich (X) unlösbar mit dem Mantel 6 des Schraubverschlusses 2 verbunden. Der übrige Umfangsbereich des Sicherheitsbandes 3 ist durch die dünnen Verbindungsstege 9 an der Unterkante 10 reissbar befestigt. Eine Sollbruchstelle 22 in Gestalt eines Einschnittes, einer Schwächungslinie oder einer filmartigen Verkleinerung der Wandstärke ermöglicht das Reissen des Sicherheitsbandes 3 beim Öffnen des Schraubverschlusses 2. Ein erster Rückhaltenocken 12a liegt benachbart der Sollbruchstelle 22 unter dem Anbindebereich X. Vorzugsweise direkt gegenüber dem Anbindebereich X ist ein einzelner oder ein Paar eng beieinander liegender Rückhaltenocken 12b ausgebildet. Um 90° versetzt dazu liegen zwei weitere Rückhaltenocken 13a, 13b. Die Rückhaltenocken 13a bzw. 13a und 13b liegen axial weiter entfernt vom unteren Rand 14 des Sicherheitsbandes 3 und gelangen deshalb beim Öffnen früher in Anlage mit der Rückhalterippe 15 als die Rückhaltenocken 12a, 12b. Die Stege 9 seitlich der Rückhaltenocken 13a und 13b sowie die Sollbruchstelle 22 werden deshalb vor den übrigen gerissen. In the embodiment of the invention according to FIGS. 5 and 6, the security band 3 is permanently connected to the jacket 6 of the screw closure 2 in the area (X). The remaining circumferential area of the security band 3 is fastened to the lower edge 10 by the thin connecting webs 9. A predetermined breaking point 22 in the form of an incision, a line of weakness or a film-like reduction in the wall thickness enables the security band 3 to tear when the screw closure 2 is opened. A first retaining cam 12a is located adjacent to the predetermined breaking point 22 below the connecting area X. A is preferably directly opposite the connecting area X. single or a pair of closely spaced retention cams 12b formed. Two further retention cams 13a, 13b are offset by 90 °. The retention cams 13a or 13a and 13b are located axially further away from the lower edge 14 of the safety band 3 and therefore come into contact with the retention rib 15 earlier than the retention cams 12a, 12b when opened. The webs 9 on the side of the retaining cams 13a and 13b and the predetermined breaking point 22 are therefore torn in front of the others.
