Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Schraubverschlußkappe aus Kunststoffmaterial nach dem Oberbegriff des Anspruchs 1.The invention is based on a screw cap Plastic material according to the preamble of claim 1.

Derartige Schraubverschlußkappen unterscheiden sich von Schraubverschlußkappen mit seperat eingelegter Dichtscheibe. Eine derartige Dichtscheibe ist bei den gattungsgemäßen Schraubverschlußkappen nicht notwendig, da die Abdichtung zwischen der Schraubverschlußkappe und dem Mündungsbereich des Behälters durch einen an der Schraubverschlußkappe befestigten Dichtungsstreifen erreicht wird. Die Schraubverschlußkappen bestehen damit aus einem Teil. Such screw caps differ from Screw caps with separately inserted sealing washer. A such a sealing washer is in the generic Screw caps are not necessary as the seal between the screw cap and the mouth area of the container by one on the screw cap attached sealing strip is reached. The Screw caps therefore consist of one part.

Aus der DE 197 05 717 A1 ist eine derartige Schraubverschlußkappe bekannt. Ein am Kappenboden angeordneter Dichtungsstreifen verformt sich beim Verschließen des Behälters mit der Schraubverschlußkappe elastisch. Im geschlossenen Zustand liegt der Dichtungsstreifen am äußeren Mündungsbereicht des Behälters an. Dabei wird der Dichtungsstreifen durch den Behälter nach außen gedrückt. Die in Richtung der Ausgangslage des Dichtungsstreifens wirkende Rückstellkraft einerseits und der Mantel der Schraubverschlußkappe andererseits sorgen für das Anliegen des Dichtungsstreifens an der Behältermündung im geschlossenen Zustand.One such is known from DE 197 05 717 A1 Screw cap known. One at the bottom of the cap Arranged sealing strip deforms when the Container with the screw cap elastic. in the when closed, the weather strip is on the outside Mouth area of the container. The Sealing strips pushed out through the container. In the Acting direction of the starting position of the sealing strip Restoring force on the one hand and the jacket of the Screw cap on the other hand ensure the concern of the Sealing strip on the container mouth in the closed Status.

Aus der WO 99 44896 A ist eine Schraubverschlußkappe gemäß dem Oberbegriff des Anspruchs 1 bekannt.From WO 99 44896 A is a screw cap known according to the preamble of claim 1.

Die Erfindung und ihre VorteileThe invention and its advantages

Demgegenüber hat die erfindungsgemäße Schraubverschlußkappe mit den kennzeichnenden Merkmalen des Anspruchs 1 den Vorteil, dass der Dichtungsstreifen beim Aufsetzen der Kappe auf den Behälter nicht nur umgelegt und zusammengedrückt sondern auseinandergezogen und um den Mündungsbereich gespannt wird. Das Spannen wird dadurch erreicht, daß der Dichtungsstreifen an dem einen Ende an der Kappe befestigt ist und das andere Ende mit der wulstartigen Verdickung zwischen dem Mündungsbereich des Behälters und einer Dichtungsringwulst an der Schraubverschlußkappe eingeklemmt wird. Die wulstartige Verdickung legt sich an der dem Kappenboden abgewandten Stirnseite der Dichtungsringwulst an. Da der Abstand zwischen der Außenseite der Dichtungsringwulst und der Innenseite des Mündungsbereichs kleiner ist als der Durchmesser der wulstartigen Verdickung des Dichtungsstreifens, wird die wulstartige Verdickung daran gehindert, zwischen die Dichtungsringwulst und die Innenseite des Mündungsbereichs einzudringen. Dies führt dazu, daß der Dichtungsstreifen gedehnt wird. Die elastische Verformung des Dichtungsstreifens beim Schließen des Behälters mit der Schraubverschlußkappe bewirkt damit nicht nur eine Positionsänderung des Dichtungsstreifens, sondern auch eine plastische Verformung desselben. Dabei legt sich der Dichtungsstreifen an die Außenseite, die Stirnseite und die Innenseite des Mündungsbreichs des Behälters an. Die Abdichtung ist damit bei der erfindungsgemäßen Schraubverschlußkappe besser als bei den aus dem Stand der Technik bekannten Schraubverschlußkappen.In contrast, the screw cap according to the invention with the characterizing features of claim 1 the advantage that the sealing strip when the cap is placed on the Containers not only folded and squeezed but pulled apart and stretched around the mouth area. Tensioning is achieved by the sealing strip on one end is attached to the cap and the other end with the bulge-like thickening between the mouth area of the Container and a sealing ring bead on the Screw cap is jammed. The beaded Thickening lies on the side facing away from the base of the cap Face of the sealing ring bead. Since the distance between the Outside of the sealing ring bead and the inside of the Mouth area is smaller than the diameter of the bead-like Thickening of the sealing strip becomes the bulge-like thickening prevented between the sealing ring bead and the Penetrate inside the mouth area. This leads to, that the weather strip is stretched. The elastic deformation of the sealing strip when closing the container with the Screw cap does not only do one Change in position of the weather strip, but also a plastic deformation of the same. The lies down Sealing strips on the outside, the front and the Inside of the mouth area of the container. The seal is thus in the screw cap according to the invention better than those known from the prior art Screw caps.

Nach einer vorteilhaften Ausgestaltung der Erfindung verläuft das dem Kappenboden zugewandte Ende des Dichtungsstreifens in axialer Richtung der Schraubverschlußkappe. Dadurch ist gewährleistet, daß der Dichtungsstreifen beim Aufsetzen der Kappe auf den Behälter umgelenkt wird und sich dabei an die Außenseite des Mündungsbereichs anlegt.According to an advantageous embodiment of the invention, this runs end of the sealing strip facing the cap bottom in axial direction of the screw cap. This is ensures that the sealing strip when putting on the cap is redirected to the container and thereby to the outside of the estuary area.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung erstreckt sich der Dichtungsstreifen in der dem Kappenboden abgewandten Richtung mindestens bis zu dem dem Kappenboden nächsten Gewindegang. Dabei ist der Durchmesser an dem dem Kappenboden abgewandten Ende kleiner als an dem dem Kappenboden zugewandten Ende. Die Länge des Dichtungsstreifens in axialer Richtung ist für das Anlegen an den Mündungsbereich von allen Seiten notwendig. Die Veränderung des Durchmessers von einem zum anderen Ende sorgt dafür, daß sich die wulstartige Verdickung des Dichtungsstreifens beim Aufsetzen der Kappe auf den Behälter an der Innenseite des Mündungsbereichs anlegt und zwischen der Innenseite und der Dichtungsringwulst eingeklemmt wird. Hierzu stimmt der Durchmesser des Dichtungsstreifens an dem dem Kappenboden abgewandten Ende ungefähr mit dem Außendurchmesser der Dichtungsringwulst überein.According to a further advantageous embodiment of the invention the sealing strip extends in the bottom of the cap opposite direction at least to that of the cap bottom next thread. The diameter is on the End facing away from the cap bottom is smaller than at the end End facing the cap bottom. The length of the weather strip in the axial direction is for contacting the mouth area necessary from all sides. The change in the diameter of one end to the other ensures that the bead-like Thickening of the sealing strip when the cap is put on creates the container on the inside of the mouth area and between the inside and the sealing ring bead becomes. The diameter of the sealing strip matches this the end facing away from the cap bottom approximately with the Outer diameter of the sealing ring bead corresponds.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der Dichtungsstreifen eine hohe Elastizität auf. Dies wird zum einen durch das Material und zum anderen durch eine geringe Dicke des Dichtungsstreifens erreicht. Als Materialien eignen sich beispielsweise Polypropylen oder Polyethylen.According to a further advantageous embodiment of the invention the sealing strip has a high elasticity. On the one hand, this becomes due to the material and the small thickness of the Sealing strip reached. Are suitable as materials for example polypropylene or polyethylene.

Nach einer vorteilhaften Ausgestaltung der Erfindung weist die wulstartige Verdickung einen runden Querschnitt auf. Sie entspricht damit einem Runddichtring. Dieser hat gegenüber einer Dichtung mit eckigem Querschnitt den Vorteil, dass er sich optimal an die beiden gegeneinander abzudichtenden Teile anlegt und den zur Verfügung stehenden Raum ausfüllt.According to an advantageous embodiment of the invention, the bead-like thickening has a round cross-section. she corresponds to an O-ring. This has opposite one Seal with an angular cross-section the advantage that it is optimal to the two parts to be sealed against each other and the available space.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist an dem dem Kappenboden abgewandten Ende der wulstartigen Verdickung des Dichtungsstreifens eine Lippe vorgesehen, die sich in axialer Richtung der Schraubverschlußkappe erstreckt. Diese sorgt für ein exaktes Positionieren der wulstartigen Verdickung an der Innenseite des Mündungsbereichs des Behälters beim Aufsetzen der Kappe auf den Behälter entlang des gesamten Umfangs der wulstartigen Verdickung. Die Lippe ragt beim Annähern der Kappe an den Behälter entlang ihres gesamtes Umfangs in das Innere des Mündungsbereichs hinein. Hierzu ist der Außendurchmesser der Lippe kleiner als der Innendurchmesser des Mündungsbereichs. According to a further advantageous embodiment of the invention at the end of the bead-like end facing away from the cap base Thickening of the weather strip provided a lip that extends extends in the axial direction of the screw cap. This ensures an exact positioning of the bulge-like thickening the inside of the mouth area of the container when putting it on the cap on the container along the entire circumference of the bead-like thickening. The lip protrudes as the cap approaches to the container along its entire circumference inside the Mouth area. For this, the outside diameter is the Lip smaller than the inside diameter of the mouth area.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind an den Kappenboden Dichtungsschultern vorgesehen. Diese sorgen für eine zusätzliche Abdichtung zwischen der Schraubverschlußkappe und dem Behälter.According to a further advantageous embodiment of the invention sealing shoulders provided on the cap base. These worry for an additional seal between the Screw cap and the container.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In Figur 1 ist eine Schraubverschlußkappe mit einem die Öffnung eines in Figur 2 erkennbaren Behälters abdeckenden Kappenboden 1 und einem ein Innengewinde 3 aufweisenden Mantel 2 dargestellt. An dem Übergang zwischen Kappenboden 1 und Mantel 2 ist am Kappenboden ein Dichtungsstreifen 4 unter einem Winkel ß gegenüber dem Kappenboden befestigt. Der Winkel beträgt etwas weniger als 90°. Der Dichtungsstreifen 4 weist an dem dem Kappenboden 1 abgewandten Ende eine wulstartige Verdickung 5 auf. Außerdem ist an dem Kappenboden 1 eine Dichtungsringwulst 6 angeordnet. Dabei sind der Dichtungsstreifen 4 und die Dichtungsringwulst 6 koaxial zur Achse der Schraubverschlußkappe vorgesehen. In axialer Richtung ändert sich der Durchmesser des Dichtungsstreifens 4. Das im Übergangsbereich zwischen Kappenboden 1 und Mantel 2 befestigte Ende des Dichtungsstreifens 4 hat einen größeren Durchmesser, so das sich dieser Bereich an die Außenseite des Mündungsbereichs anlegen kann. Das Ende mit der wulstartigen Verdickung 5 hat einen geringeren Durchmesser und kann sich damit an die Innenseite des Mündungsbereichs des Behälters anlegen. Der Bereich zwischen diesen beiden Enden liegt im auf den Behälter aufgesetzten Zustand an der Stirnseite des Behälters an. Konzentrisch zu der Dichtungsringwulst 6 und dem Dichtungsstreifen 4 ist an dem Kappenboden eine Dichtungsschulter 7 angeordnet. Ihr Durchmesser ist kleiner als der Durchmesser der Dichtungsringwulst 6 und des Dichtungsstreifens 4.In Figure 1 is a screw cap with an opening of a cap base which can be seen in FIG 1 and a jacket 2 having an internal thread 3. At the transition between cap bottom 1 and jacket 2 is on Cap bottom a sealing strip 4 at an angle ß attached to the bottom of the cap. The angle is something less than 90 °. The sealing strip 4 has the End of the cap facing away from the bead-like thickening 5 on. In addition, a sealing ring bead is on the cap base 1 6 arranged. The sealing strip 4 and the Sealing ring bead 6 coaxial to the axis of the Screw cap provided. Changes in the axial direction the diameter of the sealing strip 4. The im Transitional area between cap base 1 and jacket 2 attached The end of the sealing strip 4 has a larger diameter, so that this area is on the outside of the mouth area can put on. Has the end with the bulge-like thickening 5 a smaller diameter and can therefore adhere to the Place inside the mouth of the container. The The area between these two ends lies on the container attached state on the front of the container. Concentric to the sealing ring bead 6 and the Sealing strip 4 is a on the cap bottom Sealing shoulder 7 arranged. Their diameter is smaller than that Diameter of the sealing ring bead 6 and the sealing strip 4th

Figur 2 zeigt die Schraubverschlußkappe aus Figur 1 in einem auf den Mündungsbereich 8 eines Behälters 9 aufgeschraubten Zustand. Durch den Mündungsbereich wird der Dichtungsstreifen 4 an dem dem Kappenboden 1 zugewandten Ende in Richtung des Kappenbodens 1 umgelenkt und legt sich an die Außenseite und die Stirnseite des Mündungsbereichs an. Die wulstartige Verdickung 5 wird durch die Dichtungsringwulst 6 nach unten gedrückt. Dabei kommt es zu einer plastischen Verformung der wulstartigen Verdickung 5. Dadurch legt sich der dem Kappenboden 1 abgewandte Abschnitt des Dichtungsstreifens 4 an die Innenseite des Mündungsbereichs 8 an. Die Länge des Dichtungsstreifens ist gerade so groß, daß ein Anlegen an den Mündungsbereich 8 durch plastische Verformung möglich ist. Dabei wird die Verformung jedoch nicht durch den Kappenboden 1 begrenzt. In Figur 2 ist erkennbar, daß zwischen dem Kappenboden 1 und dem verformten Dichtungsstreifen 4 ein Hohlraum verbleibt. Durch die Verformung des Dichtungsstreifens 4 wird eine ideale Abdichtung zwischen dem Mündungsbereich 8 und der Schraubverschlußkappe erzielt. Figure 2 shows the screw cap from Figure 1 in one screwed the mouth area 8 of a container 9 Status. The sealing strip 4 is through the mouth region at the end facing the cap bottom 1 in the direction of Deflected cap bottom 1 and lies on the outside and the Face of the mouth area. The bulge-like thickening 5 is pressed down by the sealing ring bead 6. there there is a plastic deformation of the bead-like Thickening 5. This puts the cap base 1 facing section of the sealing strip 4 to the inside of the mouth area 8. The length of the weather strip is just so big that a contact with the mouth area 8 through plastic deformation is possible. The deformation but not limited by the cap bottom 1. In Figure 2 is recognizable that between the cap bottom 1 and the deformed Sealing strip 4 remains a cavity. Due to the deformation the sealing strip 4 is an ideal seal between the Mouth area 8 and the screw cap achieved.
