Abstract

The screw cap (1) is provided with a tamper-evident band (3) which is subdivided into two sections. A circumferential section (9) is connected firmly to the lower cap-edge while a complementary section (10) is designed to be tear-off and is connected to the lower cap-edge only via tear-off tabs (12). At one end of the fixed circumferential section (9) a predetermined breaking point (11) with an elastic slotted element is arranged on the tamper-evident band (3). <IMAGE>

Description

Die Erfindung betrifft eine Schraubkappe aus Kunststoffmaterial zum Verschliessen einer Behältermündung gemäss dem Oberbegriff von Anspruch 1. Derartige Schraubkappen haben eine Garantiefunktion, indem ein erstmaliges Entfernen der Kappe durch ein Abreissen des Garantiebandes angezeigt wird. Schraubkappen mit mechanisch einrastenden Garantiebändern sind bereits seit längerer Zeit bekannt und gebräuchlich.The invention relates to a screw cap made of plastic material for closing a container mouth according to the preamble of claim 1. Such screw caps have a guarantee function in that a first removal of the cap is indicated by tearing off the guarantee band. Screw caps with mechanically locking guarantee bands have been known and used for a long time.

Ein Problem bei den bekannten Kappen besteht insbesondere darin, dass das Garantieband so ausgebildet wird, dass es beim erstmaligen Oeffnen an der richtigen Stelle reisst, dass es aber beim späteren Wiederverschliessen der Behältermündung den Verschliessvorgang nicht stört. Bei Mehrwegbehältern ist ein Verbleiben des Garantiebandes an der Flaschenmündung unerwünscht, so dass das Garantieband in Umfangsrichtung aufreissen und an wenigstens einer Stelle fest mit dem unteren Kappenrand verbunden bleiben muss. Gattungsmässig vergleichbare Schraubkappen sind beispielsweise durch die EP-A-154 603 oder die EP-A-281 514 bekannt geworden.A problem with the known caps is, in particular, that the guarantee band is designed in such a way that it tears at the right place when it is opened for the first time, but that it does not interfere with the closing process when the container mouth is subsequently closed again. In the case of reusable containers, it is undesirable for the guarantee band to remain at the bottle mouth, so that the guarantee band must tear open in the circumferential direction and remain firmly connected to the lower edge of the cap at least at one point. Screw caps of the same type are known, for example, from EP-A-154 603 or EP-A-281 514.

Die vertikale Sollbruchstelle muss so ausgebildet sein, dass sie beim erstmaligen Aufschrauben der Kappe nicht reisst oder beschädigt wird. Andererseits darf die Sollbruchstelle aber auch nicht eine zu grosse Umfangselastizität bewirken, so dass die Kappe ohne Abreissen des Bandes abgeschraubt werden kann.The vertical predetermined breaking point must be designed so that it does not tear or become damaged when the cap is screwed on for the first time. On the other hand, the predetermined breaking point must not cause excessive circumferential elasticity, so that the cap can be unscrewed without tearing off the band.

Es ist daher eine Aufgabe der Erfindung, eine Schraubkappe der eingangs genannten Art zu schaffen, bei der das Garantieband beim erstmaligen Abschrauben der Kappe zuverlässig reisst, wobei es in jedem Fall mit dem Kappenkörper verbunden bleibt und ohne dass es das spätere Wiederverschliessen des Behälters beeinträchtigt. Ausserdem soll die Schraubkappe ein erstmaliges Verschliessen erlauben, ohne dass das Garantiesystem beeinträchtigt wird. Diese Aufgabe wird erfindungsgemäss mit einer Schraubkappe gelöst, welche die Merkmale im Anspruch 1 aufweist.It is therefore an object of the invention to provide a screw cap of the type mentioned, in which the guarantee tape is reliable when the cap is unscrewed for the first time tears, whereby it remains connected to the cap body in any case and without impairing the subsequent reclosing of the container. In addition, the screw cap should allow a first closing without affecting the guarantee system. This object is achieved according to the invention with a screw cap, which has the features in claim 1.

Die Materialausnehmung nimmt Materialdehnungen beim erstmaligen Aufschrauben auf und entlastet so die Sollbruchstelle. Trotzdem ist ein Abschrauben der Kappe ohne Reissen der Sollbruchstelle nicht möglich. Die Materialausnehmung kann z.B. als vertikaler Schlitz ausgebildet sein, der sich über einen Teil des Garantiebandes erstreckt. Anstelle eines Schlitzes könnte aber auch nur eine Kerbe im Garantieband angeordnet sein.The material recess absorbs material expansion when it is screwed on for the first time and thus relieves the predetermined breaking point. Nevertheless, the cap cannot be unscrewed without tearing the predetermined breaking point. The material recess can e.g. be designed as a vertical slot, which extends over part of the guarantee band. Instead of a slot, however, only one notch could also be arranged in the guarantee band.

Es hat sich überraschend gezeigt, dass es überhaupt nicht nötig ist, das Garantieband über seinen gesamten Umfang getrennt bzw. trennbar vom Kappenkörper auszubilden. Vielmehr kann das Garantieband über einen relativ grossen Umfangsabschnitt einstückig und fest mit dem unteren Kappenrand verbunden sein, wobei dieser Abschnitt nur eine Stütz- und Rückhaltefunktion hat und das symmetrische Aufsetzen der Kappe auf die Flasche ermöglicht, aber keine eigentliche Garantiefunktion übernimmt. Die Garantiefunktion wird durch den Komplementärabschnitt ausgeübt, der nicht oder nur abreissbar mit dem unteren Kappenrand verbunden ist. Dieser Abschnitt kann relativ kurz ausgebildet sein, so dass beim späteren Wiederverschliessen der Behältermündung nicht die Gefahr besteht, dass sich das abgerissene Garantieband zwischen die Gewindegänge schiebt. Das Garantieband ist über seinen gesamten Umfang durchgehend ausgebildet, wodurch die nötige Umfangsspannung beim erstmaligen Oeffnen erzielt wird. Dadurch wird ein Reissen der Sollbruchstelle am Garantieband gewährleistet.Surprisingly, it has been shown that it is not at all necessary to form the guarantee band over its entire circumference separately or separably from the cap body. Rather, the guarantee band can be integrally and firmly connected to the lower edge of the cap over a relatively large circumferential section, this section having only a support and retention function and allowing the cap to be placed symmetrically on the bottle, but does not actually perform a guarantee function. The guarantee function is exercised by the complementary section, which is not or only tearably connected to the lower edge of the cap. This section can be made relatively short, so that when the container mouth is subsequently closed again there is no danger that the torn guarantee band will be pushed between the threads. The guarantee band is continuously formed over its entire circumference, which means that the necessary circumferential tension is achieved when it is opened for the first time. This ensures that the predetermined breaking point tears on the guarantee tape.

Besonders vorteilhaft erstreckt sich der fest verbundene Abschnitt des Garantiebandes über einen Winkel von mehr als 90° und weniger als 270°, vorzugsweise von 120° bis 260°. Der nicht fest mit der Kappe verbundene Komplementärabschnitt des Garantiebandes kann über abreissbare Stege mit dem unteren Rand der Kappe verbunden sein. Dabei können jedoch bereits zwei Stege völlig ausreichen, um den Komplementärabschnitt in seiner Position festzuhalten.The firmly connected section of the guarantee band extends particularly advantageously over an angle of more than 90 ° and less than 270 °, preferably from 120 ° to 260 °. The complementary section of the guarantee tape, which is not firmly connected to the cap, can be connected to the lower edge of the cap via tear-off webs. However, two webs can be sufficient to hold the complementary section in place.

Die Rückhalteelemente sind vorzugsweise am getrennt ausgebildeten Komplementärabschnitt des Garantiebandes angeordnet, können sich aber wenigstens teilweise auch über den fest verbundenen Abschnitt erstrecken. Die Rückhalteelemente können dabei als verformbare Zungen ausgebildet sein, z.B. gemäss der EP-A-281 514 der Anmelderin. Alternativ können die Rückhalteelemente aber auch als einzelne Wulste ausgebildet sein, wie in der US-A-4,305,516 oder in der US-A-4,744,479 dargestellt. Es wäre sogar denkbar, dass als einziges Rückhalteelement ein umlaufender oder nahezu umlaufender Innenwulst am Garantieband angeordnet ist.The retaining elements are preferably arranged on the separately designed complementary section of the guarantee band, but can also extend at least partially over the firmly connected section. The retaining elements can be designed as deformable tongues, e.g. according to applicant's EP-A-281 514. Alternatively, the retaining elements can also be designed as individual beads, as shown in US-A-4,305,516 or in US-A-4,744,479. It would even be conceivable for the only retaining element to be a circumferential or almost circumferential inner bead on the guarantee band.

Weitere Vorteile können erreicht werden, wenn im Bereich des lösbaren Komplementärabschnitts wenigstens eine nach innen gerichtete Stütznase am unteren Kappenrand angeordnet ist. Diese Stütznase verhindert, dass sich der nur über wenige Stege mit dem Kappenrand verbundene Komplementärabschnitt des Garantiebandes beim erstmaligen Aufsetzen in die Kappenöffnung hineinschieben kann. Der obere Rand des Garantiebandes stützt sich vielmehr an der Nase ab, so dass ein Reissen der Abreissstege beim Aufsetzen der Kappe verhindert wird.Further advantages can be achieved if at least one inwardly directed support lug is arranged on the lower cap edge in the region of the detachable complementary section. This support lug prevents the complementary section of the guarantee band, which is connected to the edge of the cap only by a few webs, from being pushed into the cap opening when it is first put on. The upper edge of the guarantee band is rather supported on the nose, so that the tear-off bars are prevented from tearing when the cap is put on.

An embodiment of the invention is shown in the drawings and will be described in more detail below. Show it:

Figur 1 zeigt eine Schraubkappe 1 aus Kunststoffmaterial mit einem Innengewinde 5, die dazu bestimmt ist, eine Behältermündung 2 mit einem Aussengewinde 6 zu verschliessen. Derartige Schraubkappen werden bevorzugt zum Verschliessen von Flaschen mit Erfrischungsgetränken verwendet, wobei es sich in der Regel um Mehrwegflaschen aus Glas mit einer genormten Flaschenmündung handelt. Das Garantieband 3 besteht aus einem fest mit dem unteren Kappenrand verbundenen Umfangsabschnitt 9 und aus einem abreissbaren, bzw. nicht fest verbundenen Komplementärabschnitt 10. Die später noch erläuterten Rückhalteelemente auf der Innenseite des Garantiebands schnappen beim erstmaligen Aufschrauben der Kappe unter den Wulst 4 an der Behältermündung 2 und bewirken beim erstmaligen Abschrauben der Kappe die erforderliche Zugkraft zum Reissen des Garantiebandes.Figure 1 shows a screw cap 1 made of plastic material with an internal thread 5, which is intended to close a container mouth 2 with an external thread 6. Such screw caps are preferably used for closing bottles with soft drinks, which are generally reusable glass bottles with a standardized bottle mouth. The guarantee band 3 consists of a circumferential section 9 which is firmly connected to the lower edge of the cap and of a complementary section 10 which can be torn off or not firmly connected. The retaining elements, which will be explained later, on the inside of the guarantee band snap under the bead 4 at the mouth of the container when the cap is first screwed on 2 and when unscrewing the cap for the first time, cause the necessary tensile force to tear the guarantee tape.

Der Querschnitt der Schraubkappe ist aus den Figuren 2 bis 4 ersichtlich. Die Schraubkappe 1 selbst kann an ihrem Kappenboden eine Mündungsdichtung 16 oder aber auch ein anderes Dichtsystem wie z.B. eine eingelegte Dichtungsscheibe aufweisen. Die Querschnittsform der Schraubkappe und des Garantiebandes ist derart gewählt, dass eine Herstellung in einem axial öffnenden Spritzgusswerkzeug möglich ist.The cross section of the screw cap can be seen from FIGS. 2 to 4. The screw cap 1 itself can have an orifice seal 16 on its cap base or else another sealing system such as, for example, an inserted sealing washer. The cross-sectional shape of the screw cap and the guarantee band is selected such that it is manufactured in one axially opening injection mold is possible.

Aus Figur 5 ist die Länge des fest mit der Unterkante 15 verbundenen Umfangsabschnitts 9 ersichtlich. Dieser erstreckt sich beim Ausführungsbeispiel über einen Winkel Alpha von ca. 240°. Dieser Abschnitt ist, wie aus Figur 2, rechte Seite ersichtlich, praktisch in seiner ganzen Wandstärke mit der Unterkante 15 verbunden und kann somit nicht abgerissen werden.FIG. 5 shows the length of the peripheral section 9 firmly connected to the lower edge 15. In the exemplary embodiment, this extends over an angle alpha of approximately 240 °. This section, as can be seen from FIG. 2 on the right side, is connected to the lower edge 15 practically in its entire wall thickness and therefore cannot be torn off.

Der nicht fest mit dem unteren Kappenrand verbundene Komplementärabschnitt 10 erstreckt sich demgemäss über einen Winkel Beta von ca. 120°. Die Querschnittsform des Garantiebandes in diesem Abschnitt ist aus Figur 2, linke Seite ersichtlich. Das Garantieband ist oben etwa keilförmig ausgebildet und an nur zwei Abreissstegen 12 und 12' mit dem unteren Kappenrand verbunden.The complementary section 10, which is not firmly connected to the lower edge of the cap, accordingly extends over an angle Beta of approximately 120 °. The cross-sectional shape of the guarantee band in this section can be seen from FIG. 2, left side. The guarantee band is approximately wedge-shaped at the top and connected to the lower edge of the cap at only two tear-off webs 12 and 12 '.

Als Rückhalteelemente dienen nach innen gerichtete Zungen 7, unter denen je ein Stützwulst 8 angeordnet ist. Beim erstmaligen Aufschrauben der Kappe werden die Zungen 7 nach oben gebogen und gleiten so über den Wulst 4 an der Flaschenmündung. Ein Umbiegen der Zungen 7 nach unten wird durch die Stützwulste 8 verhindert, so dass die einmal unter den Wulst 4 eingerasteten Rückhalteelemente ohne Zerreissen des Garantiebandes 3 nicht mehr über den Wulst geschoben werden können.Inwardly directed tongues 7 serve as retaining elements, under each of which a support bead 8 is arranged. When the cap is screwed on for the first time, the tongues 7 are bent upwards and thus slide over the bead 4 at the bottle mouth. Bending of the tongues 7 downward is prevented by the support beads 8, so that the retaining elements once engaged under the bead 4 can no longer be pushed over the bead without tearing the guarantee band 3.

An einem Ende des festen Umfangsabschnittes 9 ist eine Sollbruchstelle 11 am Garantieband angeordnet. Wie insbesondere aus Figur 4 ersichtlich ist, besteht diese aus einem horizontalen Steg 17, der den festen Abschnitt 9 und den losen Komplementärabschnitt 10 miteinander verbindet. Um eine Ueberdehnung der Sollbruchstelle 11 beim erstmaligen Aufsetzen zu verhindern, ist unmittelbar daneben am Abschnitt 9 eine Materialausnehmung 13 in der Form eines Schlitzes vorgesehen. Dieser Schlitz erstreckt sich nur ca. über die Hälfte der Garantiebandbreite, so dass keine völlige Unterbrechung des Garantiebandes besteht. Anstelle des Schlitzes könnte auch nur eine Kerbe angeordnet werden, mit welcher die Wandstärke des Garantiebandes stark reduziert wird. Die Materialausnehmung 13 entlastet die Sollbruchstelle 11, ohne dass dabei die ungleich grösseren Dehnungskräfte beim erstmaligen Abschrauben nennenswert reduziert werden.At one end of the fixed peripheral section 9, a predetermined breaking point 11 is arranged on the guarantee band. As can be seen in particular from FIG. 4, this consists of a horizontal web 17 which connects the fixed section 9 and the loose complementary section 10 to one another. In order to prevent the predetermined breaking point 11 from being overstretched when it is put on for the first time, a material recess 13 in the form of a slot is provided directly next to the section 9. This slot extends only about half of the guarantee bandwidth, so that there is no complete interruption of the guarantee band. Instead of the slot, it would also be possible to arrange only one notch with which the wall thickness of the guarantee tape is greatly reduced. The material recess 13 relieves the predetermined breaking point 11 without significantly reducing the disproportionately large expansion forces when unscrewing for the first time.

Aus Figur 3 ist auch noch die Stütznase 14 ersichtlich, welche auf der Innenseite der Kappe im Bereich des losen Komplementärabschnitts 10 angeordnet ist. Diese, etwas schräg nach unten geneigte Stütznase verhindert, dass sich der lose Komplementärabschnitt 10 beim erstmaligen Aufschrauben der Kappe in die Kappenöffnung hineinschieben kann. Damit werden vor allem die Abreissstege 12 und 12' entlastet.FIG. 3 also shows the support lug 14, which is arranged on the inside of the cap in the region of the loose complementary section 10. This support nose, which is inclined slightly obliquely downward, prevents the loose complementary section 10 from being able to slide into the cap opening when the cap is screwed on for the first time. In particular, the tear-off webs 12 and 12 'are relieved.

Aus Figur 3 ist die Anordnung der Rückhalteelemente 7 ersichtlich, die sich über einen Winkel Delta von etwa 180° erstrecken. Drei der Rückhalteelemente liegen auf dem losen Komplementärabschnitt 10, während zwei der Rückhalteelemente 7' bereits am festen Umfangsabschnitt 9 angeordnet sind. Das erste der Rückhalteelemente liegt der Sollbruchstelle 11 etwa diametral gegenüber. Die beiden Abreissstege 12 und 12' liegen innerhalb eines Winkels Gamma von weniger als 90°, ausgehend von der Sollbruchstelle 11. Die Anzahl der Rückhalteelemente 7, der Abreissstege 12 sowie die Winkel der einzelnen Abschnitte können ersichtlicherweise den jeweiligen Gegebenheiten angepasst werden. In bestimmten Fällen wäre es auch denkbar, am Garantieband mehr als eine Sollbruchstelle 11 vorzusehen. Auch die Querschnittsform des Garantiebandes kann dem jeweiligen Einzelfall angepasst werden.FIG. 3 shows the arrangement of the retaining elements 7, which extend over an angle delta of approximately 180 °. Three of the retaining elements lie on the loose complementary section 10, while two of the retaining elements 7 'are already arranged on the fixed peripheral section 9. The first of the retaining elements lies approximately diametrically opposite the predetermined breaking point 11. The two tear-off webs 12 and 12 'lie within an angle gamma of less than 90 °, starting from the predetermined breaking point 11. The number of retaining elements 7, the tear-off webs 12 and the angles of the individual sections can obviously be adapted to the particular circumstances. In certain cases it would also be conceivable to provide more than one predetermined breaking point 11 on the guarantee band. The cross-sectional shape of the guarantee band can also be adapted to the individual case.
