Description

Die Erfindung bezieht sich auf eine Schnappverschlussanordnung an einem Behälter, mit einer Verschlusskappe mit wenigstens einem Rückhaltewulst zum Befestigen auf einer einen Aussenwulst aufweisenden Behältermündung, welcher Rückhaltewulst an einer elastisch aufweitbaren zylindrischen Wand der Verschlusskappe angeordnet ist, wobei eine Eingriffsoberfläche des Rückhaltewulstes mit einer Eingriffsoberfläche des Aussenwulstes in Wirkeingriff bringbar ist.The invention relates to a snap lock arrangement on a container, with a cap with at least a retaining bead for attachment to one Outer bead having container mouth, which retaining bead on an elastically expandable cylindrical wall Closure cap is arranged, wherein an engagement surface of the retaining bead with an engagement surface of the External bead can be brought into active engagement.

Solche Schnappverschlussanordnungen sind bekannt. Sie werden aus elastischem Kunststoffmaterial gefertigt. Meist bestehen sie aus Polyäthylen oder Polypropylen und sind einstückig im Spritzgussverfahren oder Compression Molding hergestellt. Dank der elastischen Aufweitbarkeit der zylindrischen Wand, an welcher der Rückhaltewulst angeordnet ist, kann der Rückhaltewulst über den Aussenwulst der Behältermündung hinaus nach oben gedrückt werden, wenn die Verschlusskappe von der Behältermündung abgehoben werden soll. Ebenso ist aber auch ein unbeabsichtigtes Abheben der Verschlusskappe von der Behältermündung durch einen im Inneren des Behälters herrschenden Ueberdruck möglich.Such snap lock arrangements are known. you will be made of elastic plastic material. Mostly exist They are made of polyethylene or polypropylene and are made in one piece Injection molding process or compression molding. Thanks to the elastic expandability of the cylindrical wall, on which the retaining bead is arranged, the retaining bead beyond the outer bulge of the container mouth be pushed upwards when the sealing cap of the Container mouth should be lifted off. But it is also the same an unintentional lifting of the cap from the Container mouth through a prevailing inside the container Overpressure possible.

Die Aufgabe der Erfindung besteht darin, die eingangs angegebene Schnappverschlussanordnung so auszubilden, dass die Sicherheit gegen unbeabsichtigtes Abheben der Verschlusskappe durch einen im Behälter herrschenden Ueberdruck im Vergleich zu den bekannten Schnappverschlussanordnungen erhöht ist.The object of the invention is that specified at the outset To form the snap lock arrangement so that the Security against unintentional lifting of the cap by comparison of an overpressure prevailing in the container to the known snap lock arrangements is increased.

Die Aufgabe ist in der erfindungsgemässen Schnappverschlussanordnung dadurch gelöst, dass die Eingriffsoberfläche des Rückhaltewulstes der auf der Behältermündung befestigten Verschlusskappe mit der Eingriffsoberfläche des Aussenwulstes der Behältermündung nach dem Aufsetzvorgang einen sich radial nach aussen erweiternden Spalt einschliesst, wobei der Rückhaltewulst derart elastisch deformierbar ist, dass sich der Spalt bei Überdruck im Behälter verkleinert oder schliesst.The object is in the snap lock arrangement according to the invention solved in that the engagement surface of the Retaining bead attached to the container mouth Cap with the engagement surface of the outer bead the container mouth after the installation process encloses a gap widening radially outwards, the retaining bead being so elastic is deformable that the gap in the overpressure Container shrinks or closes.

Der sich nach aussen erweiternde Spalt zwischen den beiden Eingriffsoberflächen hat die Wirkung, dass durch einen gegebenen Ueberdruck im Behälter kleinere die zylindrische Wand der Verschlusskappe aufweitende Kräfte erzeugt werden als in vergleichbaren bekannten Schnappverschlussanordnungen.The widening gap between the two Intervention surfaces has the effect of being given by a Overpressure in the container smaller the cylindrical wall the cap widening forces are generated as in comparable known snap lock arrangements.

Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnungen näher erläutert. In diesen zeigen:

  • Fig. 1 einen Vertikalschnitt durch eine erste Verschlusskappe,
  • Fig. 2 einen Vertikalschnitt durch eine zweite Verschlusskappe, die als Schraub-Schnappverschlusskappe ausgebildet ist,
  • Fig. 3 in grösserem Massstab einen Schnitt durch eine Hälfte einer Verschlusskappe und einer Mündung eines Behälters, auf welche die Verschlusskappe aufgesetzt ist,
  • Fig. 4a und Fig. 4b in einem gleichen Schnitt wie Fig. 3 einen Zustand, in welchem die Verschlusskappe durch einen im Behälter herrschenden Ueberdruck verformt ist, und
  • Fig. 5 in einem gleichen Schnitt wie Fig. 4 eine nicht erfindungsgemässe Verschlusskappe.
    • Embodiments of the invention are explained below with reference to the drawings. In these show:
  • 1 shows a vertical section through a first closure cap,
  • 2 shows a vertical section through a second closure cap which is designed as a screw snap closure cap,
  • 3 shows, on a larger scale, a section through half of a closure cap and a mouth of a container onto which the closure cap is placed,
  • 4a and 4b in a section similar to FIG. 3, a state in which the closure cap is deformed by an overpressure prevailing in the container, and
  • 5 in a section similar to FIG. 4, a closure cap not according to the invention.

    • Die in Fig. 1 gezeigte, aus Kunststoff bestehende Verschlusskappe besitzt eine kreisrunde obere Wand 1 und eine zylindrische Umfangswand 2. An der Umfangswand 2 ist innenseitig ein sich in Umfangsrichtung erstreckender Rückhaltewulst 3 angeformt. Die Umfangswand 2 ist derart elastisch aufweitbar, dass beim Aufsetzen der Verschlusskappe auf eine Mündung eines Behälters der Rückhaltewulst 3 über einen Aussenwulst an der Behältermündung gleiten und dann hinter diesem Aussenwulst einrasten kann. In gleicher Weise kann der Rückhaltewulst 3 über den Aussenwulst der Behältermündung zurückgleiten, wenn die Verschlusskappe wieder vom Behälter abgenommen wird.The closure cap shown in Fig. 1, consisting of plastic has a circular top wall 1 and a cylindrical Circumferential wall 2. On the circumferential wall 2 is on the inside a retaining bead 3 extending in the circumferential direction molded. The peripheral wall 2 can be elastically expanded, that when you put the cap on a muzzle a container of the retaining bead 3 via an outer bead slide at the container mouth and then behind this outer bead can snap into place. The retaining bead can be made in the same way 3 slide back over the outer bead of the container mouth, when the cap is removed from the container becomes.

    Die Verschlusskappe gemäss Fig. 2 besitzt in gleicher Weise wie die in Fig. 1 gezeigte die obere Wand 1 und die zylindrische Umfangswand 2. An der Umfangswand 2 sind innenseitig mehrere Rückhaltewulste 3 angeformt, die sich je nach einem Abschnitt einer Schraubenlinie erstrecken, derart, dass die Verschlusskappe auf eine Behältermündung aufgeschraubt werden kann, die ein Mehrfach-Aussengewinde trägt. Auch hier ist jedoch die Umfangswand 2 elastisch aufweitbar, so dass die Rückhaltewulste 3 über die entsprechenden, das Aussengewinde bildenden Aussenwulste an der Behältermündung gleiten können, wenn die Verschlusskappe etwa axial von der Behältermündung abgezogen oder abgekippt wird.2 has in the same way like the one shown in Fig. 1, the top wall 1 and the cylindrical Circumferential wall 2. On the circumferential wall 2 are on the inside several retaining beads 3 formed, depending on one Extend section of a helix such that the Screw cap on a container mouth can, which carries a multiple external thread. Here too however, the peripheral wall 2 is elastically expandable, so that the Retaining beads 3 over the corresponding, the external thread forming outer beads on the container mouth, when the cap is approximately axial from the container mouth is pulled or tipped.

    In Fig. 3 sind die Hälften einer Verschlusskappe und einer Behältermündung in grösserem Massstab dargestellt. Die Verschlusskappe besitzt wieder die obere Wand 1 und die Umfangswand 2 mit dem innenseitig angeformten Rückhaltewulst 3. Von der Behältermündung, auf welche die Verschlusskappe aufgesetzt ist, ist ein zylindrischer Wandabschnitt 4 dargestellt, an welchen ein Aussenwulst 5 angeformt ist. Die Verschlusskappe ist auf der Behältermündung dadurch befestigt, dass die Oberseitenfläche oder Eingriffsoberfläche des Rückhaltewulstes 3 mit der Unterseitenfläche oder Eingriffsoberfläche des Aussenwulstes 5 in Wirkeingriff steht. Die beiden Eingriffsoberflächen schliessen erfindungsgemäss, mindestens solange im Behälter kein grösserer Ueberdruck herrscht, einen sich nach aussen erweiternden Spalt ein. Im Axialschnitt schliessen die beiden Flächen (genauer: Tangenten an die Wendepunkte der Schnittlinien) etwa einen Winkel α von 5 bis 15° ein, vorzugsweise einen Winkel von 7 bis 10°.In Fig. 3, the halves of a cap and one Container mouth shown on a larger scale. The cap again has the top wall 1 and the peripheral wall 2 with the retaining bead formed on the inside 3. From the container mouth on which the cap is placed a cylindrical wall section 4 is shown, on which an outer bead 5 is formed. The cap is attached to the container mouth by the Top surface or engaging surface of the retaining bead 3 with the bottom surface or engaging surface of the Outer bead 5 is in active engagement. The two engagement surfaces close according to the invention, at least as long there is no major excess pressure in the container, one is outward widening gap. Close in axial section the two surfaces (more precisely: tangents to the turning points the cutting lines) approximately an angle α of 5 to 15 °, preferably an angle of 7 to 10 °.

    Mit dem sich nach aussen erweiternden Spalt wird die Gefahr verringert, dass die verschlusskappe durch einen im Behälter herrschenden Ueberdruck unbeabsichtigt von der Behältermündung abgehoben werden könnte. Es können mit anderen Worten höhere Ueberdrücke im Behälter zugelassen werden.With the gap widening outwards, the danger becomes Reduced the cap by one in the container prevailing overpressure unintentionally from the container mouth could be lifted off. In other words, it can higher pressures in the container are allowed.

    Die Figuren 4a und 4b zeigen die Wirkung eines im Behälter herrschenden Ueberdrucks, der die obere Wand 1 mit dem Druck P belastet und nach oben drückt. Die Wand 1 zieht dann die Umfangswand 2 nach oben, wobei sich gemäss Fig. 4a zunächst der Spalt mit dem Winkel α schliesst, weil der Rückhaltewulst 2 elastisch deformiert und nach unten gebogen wird. Aussenwulst 5 und Rückhaltewulst 3 liegen deshalb in einem weiten Bereich des vorgesehenen Innendrucks flächig aneinander an. Die Haltekraft F wird dementsprechend ebenfalls flächig über die gesamte Länge des Rückhaltewulstes 3 auf den Aussenwulst 5 des Behälters übertragen. Dadurch wird die Haltekraft F zwischen Rückhaltewulst 3 und Aussenwulst 5 in eine relativ grosse vertikal gerichtete Komponente A und eine wesentlich kleinere radial nach aussen gerichtete Komponente R zerlegt. Die nach aussen gerichtete Komponente R ist deshalb unerwünscht, weil sie auf eine Aufweitung der Umfangswand 2 der Verschlusskappe hinwirkt. Da elastische Verformung des Rückhaltewulstes 3 nicht vermieden werden kann, weil sonst die Verschlusskappe nicht auf die Behältermündung geschnappt werden könnte, wird durch den Spalt mit dem Winkel α (Fig. 3) erreicht, dass der Rückhaltewulst 3 nach dem Aufsetzen und nach dem Aufbau des zu erwartenden Ueberdrucks (z.B. bei kohlensäurehaltigen Getränken), der Rückhaltewulst 3 nach unten deformiert wird, wobei sich der Spalt schliesst und der Rückhaltewulst 3 seine Sollposition erreicht. Figures 4a and 4b show the effect of a in the container prevailing overpressure, which the upper wall 1 with the pressure P loaded and pushes up. The wall 1 then pulls the Circumferential wall 2 upwards, initially according to FIG. 4a the gap closes with the angle α because the retaining bead 2 is deformed elastically and bent downwards. Outer bead 5 and retaining bead 3 are therefore in a wide range Area of the intended internal pressure against each other. The holding force F is accordingly also flat the entire length of the retaining bead 3 on the outer bead 5 of the container transferred. As a result, the holding force F between retaining bead 3 and outer bead 5 in a relative large vertically directed component A and one essential smaller radially outward component R disassembled. The outward component R is therefore undesirable, because they are on an expansion of the peripheral wall 2 of the Cap works. Because elastic deformation of the retaining bead 3 cannot be avoided because otherwise the The cap is not snapped onto the container mouth could be, is through the gap with the angle α (Fig. 3) achieved that the retaining bead 3 after touchdown and after the build-up of the overpressure to be expected (e.g. at carbonated drinks), the retaining bead 3 after is deformed below, the gap closes and the Retaining bead 3 reaches its target position.

    Fig. 4b zeigt, wie bei weiter ansteigendem Innendruck die Haltekraft F derart vergrössert wird, dass auch die radial nach aussen gerichtete Komponente R steigt, wodurch die Umfangswand der Verschlusskappe 2 aufgeweitet wird. Aber auch bei einem derartigen Ueberdruck, wie er in Fig. 4b schematisch dargestellt ist, wird der Verschluss noch nicht vom Wandabschnitt 4 des Behälters abgesprengt.Fig. 4b shows how the with increasing internal pressure Holding force F is increased such that the radial outward component R increases, causing the Circumferential wall of the cap 2 is expanded. But also with such an overpressure as shown schematically in FIG. 4b is shown, the closure is not yet from Wall section 4 of the container blasted off.

    Im Vergleich dazu zeigt die Fig. 5 die Wirkung des im Behälter herrschenden Ueberdrucks auf eine nicht erfindungsgemässe Verschlusskappe, bei der im unbelasteten Zustand (mit unterbrochenen Linien eingezeichnet) zwischen der Oberseitenfläche des Rückhaltewulstes W und der Unterseitenfläche des Aussenwulstes 5 kein sich nach aussen erweiternder Spalt vorhanden ist. Auch hier zieht die obere Wand 1 die Umfangswand 2 etwas nach oben und gleitet dabei die Oberseitenfläche des Rückhaltewulstes W an der Unterseitenfläche des Aussenwulstes 5 schräg nach oben und aussen. Wegen des fehlenden sich nach aussen erweiternden Spaltes liegt die Berührungsstelle zwischen den beiden Wulsten weiter aussen als bei der erfindungsgemässen Verschlussanordnung von Fig. 4, und die vom Aussenwulst 5 auf den Rückhaltewulst W ausgeübte Haltekraft F' hat, bei gleicher parallel zur Behälterachse gerichteter Komponente A, eine radial nach aussen gerichtete, die Umfangswand 2 aufweitende Komponente R', die einiges grösser ist als die radiale Komponente R bei der Verschlusskappe gemäss den Fig. 3 und 4.In comparison, Fig. 5 shows the effect of in the container prevailing overpressure on a not according to the invention Cap, in the unloaded state (with interrupted Lines drawn) between the top surface of the retaining bead W and the underside surface of the outer bead 5 there is no widening gap is. Here too, the upper wall 1 pulls the peripheral wall 2 a little upwards and glides the top surface of the Retaining bead W on the underside surface of the outer bead 5 diagonally upwards and outwards. Because of the lack of after the widening gap lies between the point of contact the two beads further out than the one according to the invention 4, and that of Outer bead 5 holding force exerted on the retaining bead W. F 'has the same direction parallel to the container axis Component A, a radially outward facing, the peripheral wall 2 expanding component R ', which is a lot bigger is as the radial component R in the closure cap 3 and 4.

    Durch den sich nach aussen erweiternden Spalt, der in der erfindungsgemässen Verschlussanordnung vorhanden ist, wird also die Zunahme der im Sinne eines Aufweitens auf die Umfangswand 2 wirkenden Kraft bei im Behälter herrschendem Ueberdruck verringert.Due to the outward widening gap in the Closure arrangement according to the invention is present thus the increase in the sense of widening to the peripheral wall 2 acting force when there is in the container Overpressure reduced.
