Description

Die Erfindung betrifft einen Behälter aus Blech, wie Eimer, Hobbock oder dgl. mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a container made of sheet metal, such as a bucket, hobbock or the like. With the features of the preamble of claim 1.

Derartige Behälter mit Spannringen und Spannringverschlüssen sind seit langem all­gemein bekannt. So zeigt das deutsche Gebrauchsmuster 19 90 800 einen Spannring­verschluß, bei dem der Verschluß abweichend von der allgemeinen Krümmung des Spannringes auf seiner Länge geradlinig ausgebildet ist. Dies gilt auch für ein profiliertes Überbrückungsstück, das an dem einen Umfangsende des Spannringes fest angebracht ist und das andere Umfangsende des Spannringes verschieblich aufnimmt. Die beweglichen Elemente des Verschlusses sind so an den Teilen angelenkt, daß sie in einer Ebene beweglich sind, die senkrecht zu der Ebene des Spannringes verläuft. Das Überbrückungsstück weist einen Rastbügel auf, der in ein Fenster am freien Ende des Betätigungshebels des Verschlusses in der Schließstellung eingreift um ein Verschwenken des Hebels in Richtung Offenstellung zu verhindern. Es sind auch Spannringverschlüsse bekannt, bei denen die beweglichen Elemente des Verschlusses um Achsen schwenkbar sind, die senkrecht zu der Ebene des Spannringes verlaufen, wobei die Elemente der Umfangskrümmung des Spannringes angepaßt sind, sodaß sie satt an der Außenfläche des Spannringes in der Verschlußstellung des Behälters anliegen (vgl. deutsche GM-Schriften 72 10 719, 75 12 896 oder 76 11 482). Bei den Spannringverschlüssen gemäß den beiden zuerst genannten Gebrauchsmustern sind die Umfangsenden des Spannringes weder in der Offenstellung noch in der Schließstellung noch in irgendeiner dazwischenliegenden Stellug geführt. Bei dem Verschluß nach dem zuletzt genannten Gebrauchsmuster ist ebenfalls ein profiliertes Überbrückungsstück vorhanden, in dem in jeder Phase der Verschlußbewegung beide Umfangsenden des Spannringes aufgenommen und geführt sind, wobei das Überbrückungsstück mit dem einen Umfangsende fest verbunden ist. Im Bereich seines anderen Endes weist das Überbrückungsstück einseitig einen über die Längskante vorspringenden Lappen auf, der um die Längskante des beweglichen Umfangsendes des Spannringes zur Bildung einer Führung umgelegt ist. An diesem gleichen Ende des Überbrückungsstückes ist die Zuglasche angelenkt, während der Spannhebel im Abstand davon am Spannring selbst schwenkbar gelagert ist. In der Schließstellung liegt somit der Spannhebel direkt über dem Spannring in einem Umfangsabstand von dem die Umfangsenden des Spannringes aufnehmenden Überbrückungsstück. Bei diesem bekannten Verschluß sind zwar die Umfangsenden des Spannringes im Überbrückungsstück geführt und gesichert. Diese Sicherung reicht jedoch in vielen Fällen bei der teilweise hohen Beanspruchung des Randes eines solchen Behälters durch Einwirkung äußerer Kräfte oft nicht aus, um ein seitliches Ausweichen der Umfangsenden des Spannringes oder eine Verformung des Überbrückungsstückes auszuschließen. Auch das halbkreisförmige Profil von Spannring und Überbrückungsstück setzt darüber hinaus den möglichen hohen Beanspruchungen des Spannringverschlusses keinen ausreichend hohen Verformungswiderstand entgegen.Such containers with clamping rings and clamping ring closures have long been known. So the German utility model 19 90 800 shows a clamping ring closure, in which the closure is formed in a straight line along its length, deviating from the general curvature of the clamping ring. This also applies to a profiled bridging piece which is fixedly attached to one circumferential end of the clamping ring and slidably receives the other circumferential end of the clamping ring. The movable elements of the closure are hinged to the parts so that they are movable in a plane that is perpendicular to the plane of the clamping ring. The bridging piece has a locking bracket which engages in a window at the free end of the actuating lever of the closure in the closed position in order to prevent the lever from pivoting in the direction of the open position. Clamping ring closures are also known, in which the movable elements of the closure are pivotable about axes which are perpendicular to the plane of the clamping ring, the elements being adapted to the circumferential curvature of the clamping ring so that they fit snugly on the outer surface of the clamping ring in the closed position of the container concerns (see German GM publications 72 10 719, 75 12 896 or 76 11 482). Both Clamping ring closures according to the first two utility models mentioned are the circumferential ends of the clamping ring neither in the open position nor in the closed position nor in any position in between. In the closure according to the last-mentioned utility model, a profiled bridging piece is also present, in which both circumferential ends of the clamping ring are received and guided in each phase of the closing movement, the bridging piece being firmly connected to one circumferential end. In the area of its other end, the bridging piece has on one side a tab projecting over the longitudinal edge, which is folded around the longitudinal edge of the movable peripheral end of the clamping ring to form a guide. At this same end of the bridging piece, the pull tab is articulated, while the clamping lever is pivotally mounted at a distance from it on the clamping ring itself. In the closed position, the tensioning lever thus lies directly above the tensioning ring at a circumferential distance from the bridging piece receiving the circumferential ends of the tensioning ring. In this known closure, the peripheral ends of the clamping ring are guided and secured in the bridging piece. In many cases, however, this securing is not sufficient when the edge of such a container is subjected to high loads due to the action of external forces in order to rule out lateral deflection of the circumferential ends of the clamping ring or deformation of the bridging piece. In addition, the semicircular profile of the clamping ring and bridging piece does not counter the possible high stresses of the clamping ring closure with a sufficiently high resistance to deformation.

Es ist Aufgabe der Erfindung die aufgezeigten Nachteile zu vermeiden und einen Spannringverschluß mit den Merkmalen des Oberbegriffs des Anspruchs 1 so weiterzubilden, daß besser als bisher gewährleistet ist, daß der Spannring in jeder Phase des Schließ- oder Öffnungsvorganges und auch bei starken äußeren Beanspruchungen seine Kreisform beibehält und Spannring und Verschluß einen gegen die Einwirkung äußerer Kräfte hohen Verformungswiderstand und hohe Festigkeit zeigen und im Verschlußbereich die Umfangsenden des Spannringes zu­verlässig und wie der Verschluß selbst widerstandsfähiger gegen äußere Einwirkungen geschützt sind.It is an object of the invention to avoid the disadvantages shown and to develop a clamping ring closure with the features of the preamble of claim 1 in such a way that it is better ensured than before that the clamping ring in Every phase of the closing or opening process and even with strong external stresses maintains its circular shape and the clamping ring and closure have a high resistance to deformation and high strength against the action of external forces and the circumferential ends of the clamping ring in the closure area are reliably protected and, like the closure itself, are more resistant to external influences are.

Diese Aufgabe wird durch die Lehre des Anspruchs 1 gelöst.This object is achieved by the teaching of claim 1.

Aufgrund dieser Ausbildung erhält der Randflansch des Deckels durch die Rand­einrollung zunächst eine entsprechend erhöhte Eigenfestigkeit. Vor allem aber bildet diese Randeinrollung ein stabiles Widerlager für den Spannring, der die, bezogen auf eine horizontale Ebene, im wesentlichen nebeneinanderliegenden eingerollten Ränder von Behälterrumpf und Deckel unter hoher Flankenpressung in radialer Richtung nach innen zusammen und gegen die durch den Eindrück­deckel von innen versteifte Rumpfwand des Behälters drückt. Dadurch ergibt sich ein hoher Reibungsschluß zwischen den Teilen in radialer Richtung. Darüber hinaus wird durch die Geometrie des Deckelrandes und des Behälterrandes der Innenraum des Spannringes mit besonders hoher Aussteifung ausgefüllt, so daß der Verschluß eine hohe Formfestigkeit und einen hohen Verformungswiderstand aufweist, und so auch großen äußeren Belastungen ohne die Gefahr einer Beschädigung oder eines Lösens des Spannringes oder eines Undichtwerdens der Verbindung widerstehen kann.Due to this design, the edge flange of the cover is initially given a correspondingly increased inherent strength by the edge curl. Above all, however, this edge curl forms a stable abutment for the clamping ring, which, in relation to a horizontal plane, essentially coalesces the adjacent edges of the container body and lid under high flank pressure in the radial direction inwards and against the fuselage wall stiffened by the press-in cover from the inside of the container presses. This results in a high frictional engagement between the parts in the radial direction. In addition, the geometry of the lid edge and the container edge fills the interior of the clamping ring with particularly high stiffening, so that the closure has a high level of dimensional stability and a high resistance to deformation, and thus also large external loads without the risk of damage or loosening of the clamping ring or resist leakage of the connection.

Besonders stabil wird der Verschlußbereich dann, wenn der Rollrand gemäß der Lehre des Anspruchs 2 ausgebildet ist.The closure area becomes particularly stable when the rolled edge is designed according to the teaching of claim 2.

Für die Stabilität der Verbindung ist auch die besondere Querschnittsform des Spannringes von besonderer Bedeutung.The special cross-sectional shape of the clamping ring is of particular importance for the stability of the connection.

Die Erfindung wird nachfolgend anhand schematischer Zeichnungen an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail below with the aid of schematic drawings using an exemplary embodiment.

Es zeigen:

  • Figur 1 im Ausschnitt und im senkrechten Schnitt den Randbereich eines Behälters gemäß der Erfindung und
  • Figur 2 in ähnlicher Darstellung jedoch kleinerem Maßstab den Randbereich des zugehörigen Deckels.
Show it:
  • Figure 1 in detail and in vertical section, the edge region of a container according to the invention and
  • Figure 2 in a similar representation, but on a smaller scale, the edge region of the associated cover.

Die Teile des Behälters sind aus Blech hergestellt. Der Behälter 1 weist einen Rumpf 12 auf, dessen Randbereich nach außen spiralförmig zu einem Rollrand 13 eingerollt ist, dessen Spiralbereiche unter Flankenpressung fest aneinander und im Übergangsbereich fest an der Rumpfwand 12 anliegen. Die Spirale erstreckt sich mit ihrer freien Kante 14 um eine vorbestimmte Länge 15 über die hori­zontale Mittelebene 16 des Rollrandes 13 hinaus.The parts of the container are made of sheet metal. The container 1 has a fuselage 12, the edge region of which is rolled outward in a spiral shape to form a rolled edge 13, the spiral regions of which lie firmly against one another under flank pressure and firmly abut against the fuselage wall 12 in the transition region. The free edge 14 of the spiral extends a predetermined length 15 beyond the horizontal central plane 16 of the rolled edge 13.

Der Deckel 2 weist einen beliebig geformten Deckelspiegel 3 auf, der über eine Schulter 10 in eine Kernwand 4 übergeht, die beim Verschließen des Behälters unter Reibung in den zylindrischen Rumpf 12 eingreift. An die Kernwand 4 schließt sich ein nach unten offener, U-förmiger Randflansch 5 an, dessen oberer Bereich 6 kreisbogenförmig gekrümmt ist und außen in einen zylindrischen Schenkel 7 übergeht. Der Randbereich des Schenkels 7 ist nach außen zu einer Randeinrollung 8 umgeformt.The lid 2 has an arbitrarily shaped lid mirror 3, which merges via a shoulder 10 into a core wall 4, which engages in the cylindrical body 12 when the container is closed with friction. The core wall 4 is adjoined by a U-shaped edge flange 5 which is open at the bottom and whose upper region 6 is curved in a circular arc and merges into a cylindrical leg 7 on the outside. The edge region of the leg 7 is shaped outwards into an edge curl 8.

In dem Randflansch des Deckels 2 ist ein Dichtring, z.B. ein O-Ring 11 einge­legt, wie dies Figur 2 zeigt.A sealing ring, for example an O-ring 11, is inserted in the edge flange of the cover 2, as shown in FIG.

Der Deckel wird beim Verschließen des Behälters so weit in den Behälterrumpf eingedrückt, daß einerseits der Dichtring 11 den Freiraum zwischen Rollrand 13 und Randflansch 5 nahezu vollständig ausfüllt, wie dies Figur 1 zeigt, und daß die Unterkante 9 der Randeinrollung 8 bzw. 17 des Rollrandes 13 in einer gemeinsamen, senkrecht zur Behälterachse verlaufenden Ebene 18 liegen.The lid is pressed so far into the container body when the container is closed that on the one hand the sealing ring 11 almost completely fills the space between the rolled edge 13 and the edge flange 5, as shown in FIG. 1, and that the lower edge 9 of the edge curl 8 or 17 of the rolled edge 13 lie in a common plane 18 running perpendicular to the container axis.

In der bevorzugten Ausführungsform ist der Durchmesser der Randeinrollung 8 deutlich kleiner als der Durchmesser des Rollrandes. Vorzugsweise ist die Ein­rollung nur halb so groß oder noch kleiner als der Rollrand 13. Beide kommen in der Schließstellung in radialer Richtung nebeneinander zu liegen, wobei der Schenkel 7 in der Schließstellung unter Flankenpressung fest an dem Außenum­fang des Rollrandes 13 anliegt bzw. gegen diesen gepreßt wird.In the preferred embodiment, the diameter of the edge curl 8 is significantly smaller than the diameter of the rolled edge. The curl is preferably only half as large or even smaller than the rolled edge 13. Both come to lie next to one another in the radial direction in the closed position, the leg 7 in the closed position being pressed against the outer circumference of the rolled edge 13 or pressed against it becomes.

Hierzu dient ein Spannring 19. Dieser weist in der bevorzugten Ausführungsform ein annähernd trapezförmiges Profil auf. Sein unterer Schenkel 20 verläuft tangential zu den unteren Bereichen 9 und 17 der Randeinrollung 8 bzw. des Rollrandes 13 und liegt unter Flankenpresssung an diesen Teilen an. Von dem unteren Schenkel 20 krümmt sich das Profil des Spannringes 19 unter Flankenpressung eng um die Randeinrollung 8, wie dies bei 21 gezeigt ist bzw. über einen Teilumfang des kreisbogenförmig gekrümmten Teils 6 des Rand­flansches 6, wie das bei 23 gezeigt ist. Auch hier liegt der Spannring unter Flankenpressung an dem Randflansch 5 an. Beide gekrümmten Bereiche 21 und 23 sind durch einen geraden Profilabschnitt 22 miteinander verbunden. Von dem gekrümmten Bereich 23 erstreckt sich der obere Schenkel 24 des Spannringes radial nach innen und leicht geneigt nach oben und in der bevorzugten Aus­führungsform über die Kernwand 4 hinweg, so daß die freie Kante 25 des Schenkels 24 der Behälterachse näherliegt als die Kernwand 4. Die freie Kante des unteren Schenkels 22 ist bei 26 - ggf. unter der gezeigten Verformung - unter Pressung gegen die Rumpfwand 12 gedrückt.A clamping ring 19 is used for this purpose. In the preferred embodiment, this has an approximately trapezoidal profile. Its lower leg 20 runs tangentially to the lower regions 9 and 17 of the edge curl 8 or the rolled edge 13 and lies against these parts with flank pressure. From the lower leg 20, the profile of the clamping ring 19 curves tightly under flank pressure around the edge curl 8, as shown at 21 or over a partial circumference of the arcuate part 6 of the edge flange 6, as shown at 23. Here, too, the clamping ring lies against the edge flange 5 under flank pressure. Both curved regions 21 and 23 are connected to one another by a straight profile section 22. From the curved region 23, the upper leg 24 of the clamping ring extends radially inward and slightly inclined upward and in the preferred embodiment over the core wall 4, so that the free edge 25 of the leg 24 is closer to the container axis than the core wall 4. Die free edge of the lower leg 22 is at 26 - possibly under the deformation shown - pressed against the fuselage wall 12.

Die Trapezform des Spannringes liefert dem Spannring eine hohe eigene Form­stabilität. Diese wird durch die Profilgebung des Randflansches 5 und des Roll­randes 13 erheblich verstärkt, und zwar sowohl in axialer Richtung als auch in radialer Richtung. Der Gesamtquerschnitt des Verbindungsbereiches weist somit einen sehr hohen Verformungswiderstand auf, so daß der neue Behälter hohe äußere Belastungen durch Sturz oder Stoß sicher aufnehmen kann, ohne daß der Verbindungsbereich verformt oder beschädigt wird und ohne die Gefahr, daß der Spannring 19 sich von dem Verbindungsbereich löst.The trapezoidal shape of the clamping ring provides the clamping ring with a high level of dimensional stability. This is considerably enhanced by the profile of the edge flange 5 and the rolled edge 13, both in the axial direction and in the radial direction. The total cross section of the connection area thus has a very high resistance to deformation, so that the new container can safely absorb high external loads caused by falling or impact, without the connection area being deformed or damaged and without the risk that the clamping ring 19 detaches from the connection area .
