Description

Die Erfindung betrifft einen Blechbehälter mit Verschluß, bei dem der Blechbehälter einen Behälterstutzen mit umlaufendem, nach außen gerichteten Rastrand und eine zylindrische Innenwandung aufweist, bei dem der Verschluß mit einem Rohransatz in den Behälterstutzen eingeführt und an dessen Innenwandung dichtend anliegt, bei dem der Verschluß ein Basisteil mit Flansch aufweist, der sich dichtend auf die Stirnseite des Behälterstutzens legt, und bei dem ein Haltering mit nach innen gerichtetem Rastwulst den Rastrand des Behälterstutzens hintergreift und den Verschluß am Behälterstutzen festlegt.The invention relates to a sheet metal container with a closure, in which the sheet metal container has a container socket with a circumferential, outwardly directed latching edge and a cylindrical inner wall, in which the closure is inserted into the container socket with a tubular extension and lies sealingly against its inner wall, in which the closure is inserted Has base part with flange, which lies sealingly on the end face of the container neck, and in which a retaining ring engages behind the latching edge of the container neck with the latching bead directed inward and fixes the closure on the container neck.

Ein vorzugsweise aus Kunststoff herstellbarer Behälter dieser Art ist durch die DE-A1 35 36 514 bekannt. Der Rastrand ist dabei als umlaufender Rastwulst mit vergrößerter Wandstärke des Behälterstutzens ausgebildet. Diese Art von Rastrand ist bei einem Blechbehälter nicht leicht herstellbar. Außerdem ist der Ringteil ein vom Verschluß getrenntes Teil, das nach dem Aufstecken des Verschlusses auf den Behälterstutzen nachträglich angebracht wird.A container of this type, which can preferably be produced from plastic, is known from DE-A1 35 36 514. The locking edge is designed as a circumferential locking bead with increased wall thickness of the container neck. This type of locking edge is not easy to manufacture in a sheet metal container. In addition, the ring part is a part separate from the closure, which is subsequently attached to the container neck after the closure has been attached.

Aus der FR-A 22 81 279 ist es bekannt, den Behälterstutzen als getrenntes Teil mit einem Rastrand des Blechbehälters rastend zu verbinden, wobei der Rastrand als Kreisbogen von 180° ausgebildet ist und über sich konisch erweiternde Flankenwände in die Behälterwand übergeht. Der Verschluß ist ein weiteres Teil, das mit dem Behälterstutzen verbunden ist.From FR-A 22 81 279 it is known to connect the container neck as a separate part with a locking edge of the sheet metal container, the locking edge being designed as a circular arc of 180 ° and over flared flank walls passes into the container wall. The closure is another part that is connected to the container neck.

Aus der FR-A 15 84 609 ist ein Verschluß für einen Blechbehälter bekannt, der ein U-förmiges Basisteil aus Rohransatz und Ringteil aufweist. Der Rohransatz dichtet an der Innenwandung eines zylindrischen Behälterstutzens ab. Der Rastrand des Behälterstutzens ist ein Kreisbogen von 180°, der nach außen gerichtet ist. Der Behälterstutzen ist jedoch so eingezogen, daß er bündig mit der Behälterwand abschließt. Dabei legt sich die Außenseite des Ringteiles an einen Absatz der Behälterwand. Dies führt dazu, daß die Verrastung zwischen dem Basisteil und dem Behälterstutzen nicht optimal gestaltet werden kann, da sich die Teile im Bereich der Rastverbindung nur geringfügig auslenken lassen.From FR-A 15 84 609 a closure for a sheet metal container is known which has a U-shaped base part made of a tubular extension and a ring part. The pipe neck seals against the inner wall of a cylindrical container neck. The latching edge of the container neck is a circular arc of 180 °, which is directed outwards. However, the container neck is drawn in so that it is flush with the container wall. The outside of the ring part lies against a shoulder of the container wall. This means that the latching between the base part and the container neck cannot be optimally designed, since the parts can only be deflected slightly in the region of the latching connection.

Es ist Aufgabe der Erfindung, einen Blechbehälter mit Verschluß der eingangs erwähnten Art zu schaffen, bei dem der Behälterstutzen leicht am Blechbehälter hergestellt werden kann, bei dem kein vom Verschluß getrenntes Ringteil erforderlich ist und bei dem mit verbesserter Abdichtung der Verschluß mit eindeutiger Verrastung am Behälterstutzen angebracht werden kann.It is an object of the invention to provide a sheet metal container with a closure of the type mentioned in the introduction, in which the container neck can be easily produced on the sheet metal container, in which no ring part separate from the closure is required, and in which the seal with improved sealing has a definite latching on the container neck can be attached.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß der Behälterstutzen rohrförmig über die Ebene der Behälterwand des Blechbehälters nach außen durchgedrückt und im Bereich seiner Entnahmeöffnung zu einem Kreisbogen von 180° umgerollt ist und damit den Rastrand bildet und daß der Haltering des Verschlusses einstückig am Flansch des Basisteils angeformt und auf den Behälterstutzen gepreßt ist.This object is achieved according to the invention in that the container neck is pushed out over the level of the container wall of the sheet metal container and is rolled in the region of its removal opening to a circular arc of 180 ° and thus forms the latching edge and that the retaining ring of the closure is made in one piece on the flange the base part is molded and pressed onto the container neck.

Der Behälterstutzen bleibt zylindrisch und wird an der Behälterwand nach außen durchgedrückt. Der Rastrand wird gerollt, so daß er einen Kreisbogen von 180° bildet. Der Haltering ist am Flansch des Basisteils des Verschlusses einstückig angeformt. Da der Behälterstutzen an der Behälterwand vorsteht, kann der Haltering für eine eindeutige Rastverbindung ausreichend weit ausgelenkt werden. Das Basisteil wird auf den Behälterstutzen aufgepreßt, so daß der Flansch unter Spannung auf der Stirnseite des Behälterstutzens aufliegt und damit in diesem Bereich eine eindeutige Abdichtung zwischen dem Behälterstutzen und dem Verschluß bringt. Auf diese Weise wird nicht nur die Anbringung des Behälterstutzens am Blechbehälter, sondern auch die Ausgestaltung und Herstellung des Verschlusses einschließlich dessen Anbringung am Behälterstutzen vereinfacht und erleichtert.The container neck remains cylindrical and is pressed outwards on the container wall. The locking edge is rolled so that it forms a circular arc of 180 °. The retaining ring is integrally formed on the flange of the base part of the closure. Since the container neck protrudes from the container wall, the retaining ring can be deflected sufficiently far for a clear snap connection. The base part is pressed onto the container neck, so that the flange rests under tension on the front side of the container neck and thus brings a clear seal between the container neck and the closure in this area. In this way, not only the attachment of the container neck to the sheet metal container, but also the design and manufacture of the closure including its attachment to the container neck is simplified and facilitated.

Das Aufstecken und Aufpressen des Basisteils des Verschlusses auf den Behälterstutzen wird dadurch erleichtert, daß an dem Rohransatz konische Einführansätze angeformt sind und daß der Haltering mit einer gegenläufigen Einführschräge versehen ist, sowie dadurch, daß der Ringwulst am Haltering intermittierend ausgebildet ist.The plugging and pressing of the base part of the closure onto the container neck is facilitated in that conical insertion lugs are formed on the tube attachment and in that the retaining ring is provided with an opposing insertion slope, and in that the annular bead is formed intermittently on the retaining ring.

Die Erfindung wird anhand eines in der Zeichnung mit Teilschnitt dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail with reference to an embodiment shown in the drawing with partial section.

In der Zeichnung ist ein Verschluß 20 gezeigt, der mit einem Behälterstutzen 11 eines Blechbehälters verbunden ist. Es handelt sich dabei um einen bekannten Verschluß 20 mit einer über einen Faltenbalg 27 ausziehbaren Ausgießtülle. Die Art des Verschlusses 20 hat keinen Einfluß auf die Erfindung.In the drawing, a closure 20 is shown, which is connected to a container neck 11 of a sheet metal container. It is a known closure 20 with a pouring spout which can be pulled out via a bellows 27. The type of closure 20 has no influence on the invention.

Der Behälterstutzen 11 hat eine zylindrische Innenwandung und ist aus der Behälterwand 10 nach außen durchgedrückt, so daß er an der Behälterwand 10 absteht. Der Verschluß 20 läuft in ein U-förmiges Basisteil 21 aus, das einen Rohransatz 22 aufweist, welcher dichtend in den Behälterstutzen 11 eingeführt ist. An den Rohransatz 22 schließt sich ein Flansch 23 an, der dichtend auf der Stirnseite des Behälterstutzens 11 aufliegt. Diese Stirnseite des Behälterstutzens 11 bildet die Entnahmeöffnung und ist als Rastrand 12 mit einem Kreisbogen von 180° nach außen gerollt. An dem Flansch 23 des Basisteils 21 ist der Haltering 24 mit dem nach innen gerichteten Rastwulst 25 einstückig angeformt. Das Basisteil 21 wird beim Anbringen des Verschlusses 20 am Behälterstutzen 11 aufgepreßt, so daß sich nach dem Einrasten des Rastwulstes 25 hinter dem Rastrand 12 der Flansch 23 unter Spannung auf dem Behälterstutzen 11 liegt und in diesem Bereich eine eindeutige Abdichtung zwischen dem Basisteil 21 des Verschlusses 20 und dem Behälterstutzen 11 bringt. Der Haltering 24 hat dabei nach außen genügend Platz, um für eine ausgezeichnete Rastverbindung ausgelenkt zu werden.The container neck 11 has a cylindrical inner wall and is pushed out of the container wall 10 so that it protrudes from the container wall 10. The shutter 20 runs in a U-shaped base part 21, which has a tube extension 22 which is sealingly inserted into the container neck 11. A flange 23 adjoins the tube extension 22, which lies sealingly on the end face of the container neck 11. This end face of the container neck 11 forms the removal opening and is rolled out as a locking edge 12 with a circular arc of 180 °. The retaining ring 24 is integrally formed on the flange 23 of the base part 21 with the inwardly directed locking bead 25. The base part 21 is pressed onto the container neck 11 when the closure 20 is attached, so that after the snap-in bead 25 engages behind the latching edge 12, the flange 23 is under tension on the container neck 11 and in this area there is a clear seal between the base part 21 of the closure 20 and the container neck 11 brings. The retaining ring 24 has enough space on the outside to be deflected for an excellent locking connection.

An dem Rohransatz 22 sind konische Einführansätze 26 angebracht und auch der Haltering 24 kann eine gegenläufige Einführschräge aufweisen, so daß beim Aufpressen des Basisteils 21 auf den Behälterstutzen 11 eine Zentrierung vorgenommen wird.Conical insertion lugs 26 are attached to the tube extension 22 and the retaining ring 24 can also have an opposite insertion slope, so that centering is carried out when the base part 21 is pressed onto the container neck 11.
