Description

Behälterkörper mit zwei SchulternContainer body with two shoulders
Die vorliegende Erfindung betrifft einen Behälterkörper für einen nichtrunden Behälter mit an der Oberkante angebördeltem Deckel, dessen Seitenwand mit einer Schulter versehen ist.The present invention relates to a container body for a non-round container with a lid crimped on the upper edge, the side wall of which is provided with a shoulder.
Entstapelbare Behälterkörper sind seit langem bekannt. So wird in der US 3,233,812 ein Zellstoffbehälter offenbart, der gestapelt werden kann und dessen Seitenwand in den Eckbereichen eine Auflagenschulter besitzt.Unstackable container bodies have been known for a long time. For example, US Pat. No. 3,233,812 discloses a cellulose container which can be stacked and whose side wall has a support shoulder in the corner regions.
Die US 4,366,696 zeigt einen konischen Dosenkörper mit einem Randprofil mit drei Krümmungen, wobei von unten nach oben die erste Krümmung mit einem ersten Radius der Seitenwand (im Querschnitt gesehen) eine konvexe Form gibt und die zweiteNo. 4,366,696 shows a conical box body with an edge profile with three curvatures, the first curvature with a first radius of the side wall (seen in cross section) giving a convex shape from bottom to top and the second
Krümmung mit einem zweiten Radius ihr eine konkave Form gibt. Eine dritte Krümmung führt die Seitenwand wieder konvex nach außen, wobei der Radius dieser letzten Krümmung wesentlich größer ist als der der beiden anderen. Hierdurch wird laut Patentschrift ein Profil erzeugt, das eine glatte Oberfläche zeigt und gut entstapelbar ist, wobei die gestapelten Dosen einen gewählten Abstand voneinander besitzen.Curvature with a second radius gives it a concave shape. A third curvature leads the side wall convexly outwards again, the radius of this last curvature being considerably larger than that of the other two. According to the patent, this creates a profile that has a smooth surface and is easy to unstack, the stacked cans being at a selected distance from one another.
Die US 4,366,696 erwähnt, daß zweiteilige Dosen mit integralem Boden und Seitenwand eine bevorzugte Konstruktion darstellen, da sie Probleme bezüglich Leckagen des Bördelrandes lösen. Allerdings hat die dort gezeigte Dose den Nachteil, daß dann, wenn sich die durch die genannten Krümmungen gebildete Schulter relativ knapp unter dem oberen Ende des Seitenrandes befindet, die Stapelung zu dicht wird, so daß Probleme beim Entstapeln (wie Verklemmen und dgl.) entstehen, während dann, wenn die Schulter tiefer liegt, die Stabilität beim Bördeln nicht ausreicht, so daß fehlerhafte Bördelränder entstehen können. Aufgabe der vorliegenden-Erfindung ist es, einen Behälterkörper für einen nichtrunden Behälter zu schaffen, der auf der einen Seite gut Stapel- und entstapelbar ist, auf der anderen Seite jedoch auch eine Form aufweist, die ihn für das Aufbördeln eines Deckels besonders gut geeignet macht, weil die Bördelüberdeckung gut ist.US 4,366,696 mentions that two-piece cans with integral bottom and side wall are a preferred construction because they solve problems with flared edge leaks. However, the can shown there has the disadvantage that if the shoulder formed by the above-mentioned curvatures is located relatively just below the upper end of the side edge, the stacking becomes too dense, so that problems with unstacking (such as jamming and the like) arise , while if the shoulder is lower, the stability during the flanging is not sufficient, so that faulty flanging edges can arise. The object of the present invention is to provide a container body for a non-round container which can be easily stacked and unstacked on the one hand, but on the other hand also has a shape which makes it particularly suitable for flanging a lid because the flare coverage is good.
Überraschenderweise konnte gefunden werden, daß solche Behälterkörper sowohl eine gute Entstapelbarkeit als auch gute Stabilität beim Anbördeln des Deckels aufweisen, derenSurprisingly, it was found that such container bodies have both good unstackability and good stability when the cover is flanged, the
Seitenwand mit einer Schulter aus einer ersten und einer zweiten Schulter versehen ist, wobei die erste Schulter in mindestens einem Teil derjenigen Bereiche, die in der Aufsicht gesehen langgestreckt oder im Vergleich zu anderen Teilbereichen weniger stark gekrümmt sind, näher zur Oberkante des Behälters hin angeordnet ist als die zweite Schulter in den restlichen Bereichen und wobei die Seitenwand mindestens in Teilbereichen der Bereiche, in denen die erste Schulter vorhanden ist, in der Seitenaufsicht im wesentlichen senkrecht verlaufende Seitenriffel aufweist, die oberhalb der Höhe auslaufen, in welcher die zweite Schulter angeordnet ist . Die Führung der Seitenriffel bis über die Höhe der zweiten Schulter bewirkt eine extrem gute Wandsteifigkeit, so daß die auf die Seitenwand übertragene Kraft der Bördelwerkzeuge beim Bördeln nicht zu deren Verformung führt .Sidewall is provided with a shoulder of a first and a second shoulder, the first shoulder being arranged closer to the upper edge of the container in at least a part of those regions which, when viewed from above, are elongated or less curved than other partial regions than the second shoulder in the remaining areas and wherein the side wall has at least in partial areas of the areas in which the first shoulder is present, in the side view, substantially perpendicular side corrugations which run out above the height at which the second shoulder is arranged. The guidance of the side flutes up to the height of the second shoulder results in extremely good wall rigidity, so that the force of the flanging tools transmitted to the side wall does not lead to their deformation during flanging.
Die Mündung der ersten in die zweite Schulter kann beliebig ausgestaltet sein. So kann z.B. die erste Schulter bogenförmig zur zweiten Schulter geführt werden. Nachfolgend soll die Erfindung anhand von beispielhaften Zeichnungen näher erläutert werden.The opening of the first into the second shoulder can be designed in any way. For example, the first shoulder can be arched to the second shoulder. The invention will be explained in more detail below with the aid of exemplary drawings.
Figur 1 zeigt einen Teil eines erfindungsgemäßen Behälterkörpers in Seitenansicht. Die Bodenfläche 5 geht einstückig in eine leicht nach außen geneigte Seitenwand 2 über. Im linken Teil der Figur, der einen in der Aufsicht gesehenen geraden oder nur leicht gekrümmten Teilbereich des Behälters darstellt, ist die erste Schulter la angeordnet, während im rechten TeilFigure 1 shows a part of a container body according to the invention in side view. The bottom surface 5 merges in one piece into a slightly outwardly inclined side wall 2. The first shoulder la is arranged in the left part of the figure, which represents a straight or only slightly curved partial region of the container, as seen in the top view, while in the right part
(in der Aufsicht stärker gekrümmt) die zweite Schulter lb zu sehen ist, die weniger nah an der Oberkante 3 des Behälters verläuft als die erste Schulter. Nicht ganz bis zum Ende des Bereiches mit der Schulter la erstreckt sich ein Bereich mit(more curved in the view) the second shoulder 1b can be seen, which runs less close to the upper edge 3 of the container than the first shoulder. An area does not extend all the way to the end of the area with the shoulder la
Seitenriffeln 4, die oberhalb der Höhe der Schulter lb auslaufen. Die Seitenwand besitzt oberhalb der Höhe der zweiten Schulter lb Abschnitte 2a, 2b, 2c wobei die oberen Abschnitte 2a, 2b oberhalb der Schultern la,lb weniger stark nach außen geneigt sind als der restlicheSide corrugations 4, which run out above the height of the shoulder 1b. The side wall has sections 2a, 2b, 2c above the height of the second shoulder 1b, the upper sections 2a, 2b above the shoulders 1a, 1b being less inclined outwards than the rest
Teil der Schulter 2. Der Übergang 8 zwischen den beiden Schultern la,lb verläuft in einem kleinen Bogen.Part of the shoulder 2. The transition 8 between the two shoulders la, lb runs in a small arc.
Figur 2 stellt einen vergrößerten Ausschnitt aus Figur 1 dar, der einen Seitenriffel 4 zeigt. 7 bezeichnet die Kante, die durch einen nur geringfügig von 180° abweichenden stumpfen Winkel in der Seitenwand 2 gebildet wird.FIG. 2 shows an enlarged detail from FIG. 1, which shows a side corrugation 4. 7 denotes the edge which is formed by an obtuse angle in the side wall 2 which differs only slightly from 180 °.
Figur 3 zeigt Seitenkanten 2 zweier ineinander gestapelter Behälterkörper 6,6' gemäß Figur 1. Von jedem der beidenFIG. 3 shows side edges 2 of two container bodies 6, 6 'stacked one inside the other according to FIG. 1. Of each of the two
Behälterkδrper 6,6' ist eine Seitenkante mit einer ersten Schulter la und eine solche mit einer zweiten Schulter lb übereinandergelegt dargestellt. Dabei erscheint die Seitenkante mit der Schulter la als schwarz durchgezogener Balken, während die Schulter lb als ungefüllter Balken dargestellt ist. Auch hier ist erkennbar, daß in dieser Ausführungsform die oberen Abschnitte 2a, 2b und 2c der Seitenwand 2 eine identische Neigung besitzen und etwas weniger stark nach außen geneigt sind als der untere Teil der Seitenwand 2. Zu erkennen ist weiterhin die Geometrie eines Seitenriffeis 4, dessen Auslauf in dieser Ausführungsform oberhalb der Schulter lb beginnt und auf der Mitte zwischen den Höhen der beiden Schultern endet .Container body 6, 6 'shows a side edge with a first shoulder la and one with a second shoulder lb superimposed. The side edge with the shoulder la appears as a solid black bar, while the shoulder lb is shown as an unfilled bar. It can also be seen here that in this embodiment the upper sections 2a, 2b and 2c of the side wall 2 are one have the same inclination and are slightly less inclined outwards than the lower part of the side wall 2. The geometry of a side reef 4 can also be seen, the outlet of which in this embodiment begins above the shoulder 1b and ends in the middle between the heights of the two shoulders .
Figuren 4 bis 6 zeigen weitere Ausführungsformen des Behälterkörpers, die sich von der in Figur 1 bis 3 gezeigten nur durch die Form und die Höhe des Auslaufs der Riffelung 4 unterscheiden. FIGS. 4 to 6 show further embodiments of the container body, which differ from the one shown in FIGS. 1 to 3 only in the shape and the height of the outlet of the corrugation 4.
Die Erfindung ist geeignet für alle Behälterkörper, die in der Aufsicht mindestens eine Krümmung aufweisen, sofern keine exakte Kreisform vorliegt. Insbesondere fallen darunter ovale oder in anderer Form langgestreckte, gerundete Behälterkörper wie solche für Fischdosen, aber auch solche, die mehr oder weniger stark gerundete Ecken aufweisen.The invention is suitable for all container bodies which have at least one curvature when viewed from above, provided that there is no exact circular shape. In particular, this includes oval or other elongated, rounded container bodies, such as those for fish cans, but also those which have more or less rounded corners.
Die Behälterkörper können aus einem beliebigen Material εein, vorausgesetzt, daß es sich zur Zusammenbördelung mit einemThe container body can be made of any material, provided that it can be crimped with a
Deckel eignet. Hierunter fallen beispielsweise alle Arten von Blechen oder beschichteten Metallen, aber auch Kunststoffe oder aus Naturstoffen hergestellte, ggf. entsprechend modifizierte oder an der Oberfläche bearbeitete oder beschichtete Materialien.Cover. This includes, for example, all types of sheet metal or coated metals, but also plastics or materials made from natural materials, which may be modified or processed or coated on the surface.
Der Boden des erfindungsgemäßen Behälterkδrpers kann je nach Bedarf beliebig gestaltet sein, z. B. kann er flach sein oder auch Einwölbungen oder Auswölbungen besitzen. Der Boden geht in die Seitenwand über, wobei die beiden genannten Teile einstückig sein können oder aber durch Bördel- oder Schweißnähte oder anderweitig aus mehreren Teilen verbunden sein können. Die Seitenwand kann senkrecht nach oben verlaufen oder mehr oder weniger stark nach außen geneigt sein.The bottom of the container body according to the invention can be designed as required, for. B. it can be flat or also have bulges or bulges. The floor merges into the side wall, and the two parts mentioned can be in one piece or can be connected by flared or welded seams or otherwise made up of several parts. The side wall can run vertically upwards or be more or less inclined outwards.
Infolge der Form des Behälterkörpers hat er in der Aufsicht gesehen Bereiche, die stärker gekrümmt sind, sowie Bereiche, die weniger stark gekrümmt oder langgestreckt sind. Eine ovale, übliche Fischdose beispielsweise ist am Aufreißbereich und an der gegenüberliegenden Seite stärker gekrümmt als in den dazwischen liegenden Bereichen, die meist teilweise gerade verlaufen. Eine vierseitige Dose mit gerundeten Ecken besitzt vier stark gekrümmte Bereiche, während die dazwischen liegenden Bereiche gerade sind. Der erfindungsgemäße Behälterkörper besitzt in mindestens einem Teil der genannten geraden oder weniger stark gekrümmten Bereiche eine erste Schulter, die relativ nah zur Oberkante des Behälters hin angeordnet ist. In den stärker gekrümmten Bereichen verläuft eine zweite Schulter, die als Auflagenschulter -zum Stapeln und EntStapeln dienen kann. Die erste Schulter kann beispielsweise in einer Entfernung zur Oberkante des Behälters hin angeordnet sein, die zwischen 30% und 50% der Entfernung der zweiten Schulter von der Oberkante beträgt. Selbstverständlich sind je nach Bedarf auch andere Abmessungen möglich.As a result of the shape of the container body, when viewed from the top, it has areas that are more curved and areas that are less curved or elongated. For example, an oval, conventional fish can is more curved on the tear-open area and on the opposite side than in the areas in between, which are mostly straight. A four-sided box with rounded corners has four strongly curved areas, while the areas in between are straight. The container body according to the invention has a first shoulder in at least part of the said straight or less strongly curved regions, which is arranged relatively close to the upper edge of the container. In the more curved areas there is a second shoulder, which can serve as a support shoulder for stacking and unstacking. The first shoulder can be arranged, for example, at a distance from the upper edge of the container that is between 30% and 50% of the distance of the second shoulder from the upper edge. Of course, other dimensions are also possible depending on requirements.
Mindestens in Teilbereichen der Bereiche, in denen die erste Schulter vorhanden ist, besitzt die Seitenwand zusätzlich eine Riffeiung. Diese Riffeiung verläuft in der Seitenaufsicht im wesentlichen senkrecht und folgt der Wandneigung. Die Seitenriffel erstrecken sich über die Höhe hinweg, in welcher die zweite Schulter angeordnet ist, und laufen bevorzugt auf etwa halber Höhe zwischen den beiden Schulterhöhen oder in Höhe der oberen, ersten Schulter aus. Durch das Hochziehen derAt least in some areas of the areas where the first shoulder is present, the side wall also has a corrugation. This reefing is essentially vertical in the side view and follows the slope of the wall. The side corrugations extend over the height at which the second shoulder is arranged and preferably run out at about half the height between the two shoulder heights or at the height of the upper, first shoulder. By pulling up the
Seitenriffel über die Höhe der zweiten Schulter hinaus ergibt sich eine verbesserte Wandsteifigkeit, so daß im Zusammenwirken mit der relativ kurz unter der Oberkante angeordneten ersten Schulter in den langgestreckten oder wenig stark gekrümmten Bereichen sichergestellt ist, daß beim Anbördeln des Deckels die Überdeckung der beiden Teilbereiche besser und sicherer gelingt als bei bisher bekannten Behälterkörpern.Side corrugations beyond the height of the second shoulder also result in improved wall rigidity, so that in cooperation with the first shoulder arranged relatively short below the upper edge in the elongated or slightly curved areas, it is ensured that the overlap of the two partial areas is better when the cover is flanged and succeeds more safely than with previously known container bodies.
In einer bevorzugten Ausführungsform wird mindestens eine der beiden Schultern dadurch gebildet, daß die Seitenwand, im Querschnitt gesehen und von oben nach unten angegeben, erst kreisbogenförmig auswärts und dann kreisbogenförmig einwärts geführt wird. Die beiden dabei eingesetzten Radien können identisch oder verschieden sein. In einer besonderen Ausführungsform beschreibt das erste Kreisbogensegment, mit dem die Seitenwand nach außen geführt wird, einen kleineren Kreisbogenabschnitt als das zweite Segment. Infolgedessen besitzt die Seitenwand oberhalb der Schulter eine geringere Neigung nach außen als die Seitenwand unterhalb der Schulter. Wenn der untere Teilbereich der Seitenwand nur sehr wenig nach außen geneigt ist, kann der genannte Teilbereich der Seitenwand, der sich oberhalb der Schultern befindet, dann z. B. auch senkrecht zur Bodenfläche ausgebildet sein. Die vorstehend beschriebene Ausführung der Kreisbögen eignet sich besonders für die zweite Schulter. Es ist besonders bevorzugt, daß die Seitenwand in den in der Aufsicht gesehen langgestreckten oder im Vergleich zu anderen Teilbereichen weniger stark gekrümmten Bereichen auf der Höhe der zweiten Schulter stumpfwinklig mit einem Winkel, der nur wenig kleiner als 180° ist, nach innen gewinkelt ist. Ganz besonders bevorzugt ist es, daß die Wahl der Radien und der Länge der Kreisbogenabschnitte der zweiten Schulter und die Wahl des auf Höhe dieser Schulter vorhandenen stumpfen Winkels in den Bereichen, in denen die zweite Schulter nicht vorhanden iεt, εo aufeinander abgestimmt sind, daß die Seitenwand auf der Höhe zwischen der ersten und der zweiten Schulter einen konstanten Winkel zum unteren Bereich der Seitenwand bzw. zur Bodenfläche besitzt, unabhängig davon, ob die Dose in der Aufsicht gesehen an dieser Stelle stärker, weniger stark oder gar nicht gekrümmt ist .In a preferred embodiment, at least one of the two shoulders is formed in that the side wall, viewed in cross section and indicated from top to bottom, is first guided outward in a circular arc and then inward in a circular arc. The two radii used can be identical or different. In a special embodiment, the first circular arc segment, with which the side wall is guided to the outside, describes a smaller circular arc section than the second segment. As a result, the sidewall above the shoulder is less inclined outward than the sidewall below the shoulder. If the lower portion of the side wall is only slightly inclined outwards, said portion of the side wall, which is located above the shoulders, can then e.g. B. also be formed perpendicular to the floor surface. The design of the arcs described above is particularly suitable for the second shoulder. It is particularly preferred that the side wall in the regions which are elongated in the view from above or are less curved in comparison to other partial areas at the height of the second shoulder are angled inward at an angle which is only slightly less than 180 °. It is very particularly preferred that the choice of the radii and the length of the arc sections of the second shoulder and the choice of the obtuse angle at the level of this shoulder in the areas in which the second shoulder is not present are so coordinated that the Side wall at the height between the first and the second shoulder has a constant angle to the lower region of the side wall or to the floor surface, regardless of whether the can is seen at this point more, less strongly or not at all from the top.
Die vorstehenden Ausführungen sind selbstverständlich ohneThe above statements are of course without
Einbeziehung der Seitenriffelung gemacht. Es ist klar, daß an den Orten, an denen die Seitenwand infolge des Vorhandenseins eines Riffeis nach innen zurückspringt, die Geometrie verändert ist.Inclusion of side corrugation made. It is clear that where the side wall bounces inward due to the presence of a reef ice, the geometry is changed.
