Abstract

A container comprising a web or blank of material of limited flexibility with wall portions in which at least one edge is separated from a bent-over edge strip portion by a bend line, is provided with a maximum degree of stability so as to avoid any outward bulging and to resist the resilient forces tending to cause a return to an initial position. For that purpose, the bend line is interrupted by at least one geometrical surface portion serving as a stabilizing member which projects both into the edge strip portion and also into the wall portions, and which is separated from both by desired or predetermined bend lines. The blank can be made of cardboard with a coating of aluminum film or foil, for lining the interior of the container and the bend line is interrupted by at least one geometrical surface portion which projects into both portions of the blank, which are adjacent to the bend line, that is to say, the edge strip portion and the wall portion, and the stabilizing member is separated from the edge strip portion and the wall by bend lines which are at least partly cut. In both cases, at least the bend line is preferably produced by stamping or embossing, or by perforations.

Description

Die Erfindung betrifft einen Behälter aus einer begrenzt flexiblen Werkstoffbahn, insbesondere Karton, mit Wandungsteilen, bei denen wenigstens eine Kante durch eine Knicklinie von einem abgewinkelten Randstreifen getrennt ist.The invention relates to a container made of a material web of limited flexibility, in particular cardboard, with wall parts in which at least one edge is separated from an angled edge strip by a crease line.

Behälter dieser Art sind in vielen Bereichen des täglichen Lebens einsetzbar, sei es als runder Behälter, wie Eimer, Jogurtbecher od. dgl., sei es in polygonaler Form, wie beispielsweise als rechteckige Backform.Containers of this type can be used in many areas of everyday life, be it as a round container, such as buckets, yoghurt pots or the like, or be it in a polygonal shape, such as a rectangular baking pan.

Zu manchen Gebrauchszwecken hat es sich weiterhin als praktisch erwiesen, die Behälter zu flachen Versandstücken gefaltet dem Handel anzubieten. Insbesondere sind hier Faltbackformen bekannt, welche der fertigen Backmischung beigefügt sind. Sie werden von der Hausfrau bei Bedarf auseinandergeklappt, mit dem Backgut gefüllt und in den Ofen geschoben.For some purposes, it has also proven practical to offer the containers folded to flat packages for sale. In particular, folding baking tins are known here, which are added to the finished baking mixture. If necessary, the housewife will unfold them, fill them with the baked goods and put them in the oven.

Bekannte Behälter dieser Art weisen von ihrer oberen Wandungskante abkragende Randstreifen auf, welche unter anderem der Stabilisierung der Behälterwandung dienen sollen. Es hat sich jedoch beim praktischen Gebrauch dieser Behälter herausgestellt, daß trotz der angeformten Randstreifen die Wandungsteile ausbauchen bzw. ihre Form verlieren. Dies ist unter anderem darauf zurückzuführen, daß beispielsweise bei den aus einem Zuschnitt hergestellten faltbaren Behältern die Randstreifen nicht sachgemäß umgeknickt werden und dann während des Gebrauchs die notwendige Abwinkelung von etwa 90° zu den Wandungsteilen nicht einhalten. Dieser Rückstellvorgang wird beispielsweise bei einer Backform noch durch die Hitzeeinwirkung begünstigt.Known containers of this type have edge strips which project from their upper wall edge and which, among other things, are intended to stabilize the container wall. However, it has been found in practical use of these containers that, despite the molded-on edge strips, the wall parts bulge or lose their shape. This is due, among other things, to the fact that, for example, in the case of the foldable containers produced from a blank, the edge strips are not folded properly and then do not maintain the necessary angle of about 90 ° to the wall parts during use. In a baking pan, for example, this reset process is further promoted by the effects of heat.

Da aber gerade die Einhaltung einer vorgegebenen Form eine der wesentlichen Aufgaben eines Behälters ist , hat sich der Erfinder zum Ziel gesetzt, die aus einem rückstellfähigen, also begrenzt elastischen Werkstoff bestehenden Wandungsteile bzw. Randstreifen so zu gestalten, daß eine höchstmögliche Stabilität erfolgt, jegliche Ausbauchung vermieden und den Rückstellkräften entgegengewirkt wird.However, since compliance with a predetermined shape is one of the essential tasks of a container, the inventor has set itself the goal of designing the wall parts or edge strips consisting of a resilient, that is to say limited elastic material in such a way that the greatest possible stability takes place, any bulging avoided and counteracting the restoring forces.

Zur Lösung dieser Aufgabe führt, daß die Knicklinie durch wenigstens eine geometrische Fläche unterbrochen ist, welche sowohl in den Randstreifen als auch-andererseits in den Wandungsteil einragt und von beiden durch-Sollknicklinien getrennt ist.To achieve this object, the crease line is interrupted by at least one geometric surface which protrudes both into the edge strips and, on the other hand, into the wall part and is separated from both by predetermined crease lines.

Diese Anordnung hat den überraschenden Effekt gezeigt, daß der Randstreifen,einmal aus der Ebene des Wandungsteils herausgebogen,nicht mehr von sich aus in seine Ausgangslage zurückkehrc. Ebenso vollzieht er keine weitergehende selbstständige Knickung um etwa 180°, wodurch seine stabilisierende Wirkung gleichfalls aufgehoben würde. Er verharrt etwa in einem Winkel von 90° zum Wandungsteil und erreicht dadurch ein Verbleiben in seiner wirkungsvollsten Stellung.This arrangement has shown the surprising effect that the edge strip, once bent out of the plane of the wall part, no longer automatically returns to its starting position. Likewise, it does not undergo any further independent bending by approximately 180 °, which would also nullify its stabilizing effect. It remains at an angle of 90 ° to the wall part and thereby remains in its most effective position.

Diese Erfindung dient in noch höherem Maße der Stabili-sierung von Behältern, welche aus einem Zuschnitt erst in den gebrauchsfertigen Zustand gefaltet werden müssen. Als Beispiel sei hier ein Kartonzuschnitt mit einer den Behälterinnenraum auskleidenden Beschichtung aus beispielsueise Aluminiumfolie gewählt, wie er etwa für eine Backform Anwendung findet. Für eine Backform dieser Art wird besonders Schutz begehrt.This invention serves to an even greater extent to stabilize containers which first have to be folded from a blank into the ready-to-use state. As an example, a cardboard blank with a coating lining the interior of the container made of, for example, aluminum foil, is chosen, such as is used for a baking pan. Protection is particularly sought after for a baking pan of this type.

Der erfinderische Gedanke umfaßt aber nicht etwa nur dieses Ausführungsbeispiel oder nur Behälter, sondern ist immer dann anwendbar, wenn durch zwei in einem Winkel zueinander verlaufende Flächen eine Stabilisation entweder nur dieser Flächen zueinander oder eines ganzen Körpers erreicht werden soll. Das bedeutet, daß der erfinderische Gedanke, losgelöst von Behälter oder gar Backform, allein schon darin zu sehen ist, daß eine Knicklinie zwischen zwei zueinander abgewinkelten Flächen durch wenigstens eine geometrische Fläche unterbrochen ist, welche sowohl in die eine als auch in die andere Fläche einragt und von beiden durch Sollknicklinien getrennt ist.However, the inventive idea does not only include this exemplary embodiment or only containers, but can always be used if two surfaces which run at an angle to one another are intended to stabilize either only these surfaces with respect to one another or an entire body. This means that the inventive idea, detached from the container or even the baking mold, can be seen in the fact that a kink line between two angled surfaces is interrupted by at least one geometric surface which protrudes into both the one and the other surface and is separated from both by nominal buckling lines.

Auch für diesen übergeordneten Erfindungsgedanken wird selbständig Schutz begehrt. Auf diesen sind auch die nachfolgend beschriebenen Unteransprüche ebenso rückbeziehbar, obwohl sie in der vorliegenden Erfindung lediglich anhand des Beispiels eines Behälters beschrieben werden.Protection is also sought independently for this overarching inventive idea. The subclaims described below can also be referenced to these, although in the present invention they are only described using the example of a container.

Die technische Ausgestaltung sowohl der KnickliniEn als auch der Sollknicklinien kann nun durch unterschiedliche oder gleiche Maßnahmen erfolgen. Einfach wäre es vohl, die Knicklinie und/oder die Sollknicklinien durch Prägung zu erzeugen. Anderseits hat es sich als günstig erwiesen die Knicklinie und die Sollknicklinien zu perforieren. Auch eine Ritzung der Knicklinie und/oder der Sollknicklinie ist denkbar. Erfindungsgemäß können aber je nach Bedarf Prägung, Perforation und Ritzung kombiniert oder ausgetauscht werden.The technical configuration of both the folding lines and the predetermined folding lines can now be carried out using different or the same measures. It would simply be vohl to emboss the crease line and / or the desired crease lines. On the other hand, it has proven to be advantageous to perforate the crease line and the nominal crease lines. It is also conceivable to scratch the fold line and / or the predetermined fold line. According to the invention, however, embossing, perforation and scoring can be combined or exchanged as required.

Möglich ist ebenfalls, daß Teile der Sollknicklinie jeweils nach Gestaltung der geometrischen Figur angestanzt sind. Hat beispielsweise die geometrische Figur die Form eines Sechsecks, so können die Knicklinie und die zu dieser etwa versetzt parallel verlaufenden Teile der Sollknicklinie perforiert, die von den Sollknicklinien zur Knicklinie hin verlaufenden Seiten des Sechsecks ausgestanzt sein. Diese Anordnung verhindert ein schalenförmiges Einbeulen der Sechseckfläche, da die beiden in der Knicklinie liegenden Ecken des Sechsecks nicht durch Zug beansprucht werden.It is also possible for parts of the predetermined bending line to be punched out in each case according to the design of the geometric figure. If, for example, the geometric figure has the shape of a hexagon, the fold line and the parts of the nominal fold line which run parallel to it and offset approximately parallel to it can be perforated, and the sides of the hexagon extending from the nominal fold lines to the fold line can be punched out. This arrangement prevents the hexagonal surface from buckling in the form of a bowl, since the two corners of the hexagon lying in the fold line are not subjected to tensile stress.

Umgeben dagegen die Sollknicklinien eine etwa mandelbis ellipsenförmige Fläche und sind sie nur perforiert, so bilden sie beim Abuinkeln des Randstreifens eine schalenförmige Innenfläche aus.If, on the other hand, the predetermined crease lines surround an approximately almond-shaped elliptical surface and if they are only perforated, they form a bowl-shaped inner surface when the edge strip is bent.

Die geometrische Fläche kann aber auch ein Kreis oder ein Polygon sein.The geometric surface can also be a circle or a polygon.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in:

  • Fig. 1: eine Schrägsicht auf eine Backform;
  • Fig. 2: die Draufsicht auf eine Hälfte des Zuschnittes zur Herstellung der Backform;
  • Fig. 3: eine weitere Ausführungsform eines vergrößerten Details aus Fig. 1 in Schrägsicht.
Further advantages, features and details of the invention emerge from the following description of preferred exemplary embodiments and with reference to the drawing; this shows in:
  • 1: an oblique view of a baking pan;
  • 2: the top view of one half of the blank for producing the baking mold;
  • 3: a further embodiment of an enlarged detail from FIG. 1 in an oblique view.

Eine kastenartige, nach oben offene Backform 1 der Länge a von beispielsweise 250 mm besteht aus einem Boden 2, der Breite b von 70 mm, zwei zueinander in einem Winkel w geneigt verlaufenden Seitenwänden 3 der Höhe h von etwa 75 mm sowie zwei Stirnwänden 4. Durch die Längsachse M der Backform 1 und die dazu senkrechte Mittellinie N der Stirnwand 4 ist die Symmetrieebene der Form bestimmt.A box-like baking mold 1 of length a of up to 250 mm, for example, consists of a base 2, width b of 70 mm, two side walls 3 of height h of approximately 75 mm, inclined at an angle w, and two end walls 4. The plane of symmetry of the shape is determined by the longitudinal axis M of the baking mold 1 and the center line N perpendicular to the end wall 4.

Jede Stirnwand 4 weist zwei Klappstreifen 5 auf, von denen jeder mit einer Seitenwand 4 entlang einer Knicklinie 20 verbunden ist. Den Klappstreifen 5 ist eine Klappzunge 6 zugeordnet, die entlang einer Knicklinie 21 am Boden 2 hängt und die Oberkante 7 der Seitenwand 4 als Grifflasche 8 überragt. Die Klappzunge 9 ist aus einem sich nach oben zur Grifflasche 8 hin verjüngenden Mittelsteg 9 und zwei beidseits anschließenden Flügeln 10 zusammengesetzt. Die Seitenkante jedes Flügels 10 verläuft vom Boden 2 ab in einem unteren Kantenabschnitt 12 etwa parallel zur Kante des Mittelstegs 9 und einer äußeren Soll-Reißlinie 14 bis zu einer Einengung, von der ab ein oberer Kantenabschnitt 13 nach außen zur Oberkante 15 der Seitenwand 3 gerichtet ist. Entlang dieser ist ein schmaler Randstreifen 16 zu erkennen.Each end wall 4 has two folding strips 5, each of which is connected to a side wall 4 along a fold line 20. The folding strips 5 are assigned a folding tongue 6 which hangs on the bottom 2 along a fold line 21 and projects above the upper edge 7 of the side wall 4 as a grip tab 8. The folding tongue 9 is composed of a central web 9 tapering upwards towards the grip tab 8 and two wings 10 adjoining on both sides. The side edge of each wing 10 runs from the bottom 2 in a lower edge section 12 approximately parallel to the edge of the central web 9 and an outer predetermined tear line 14 up to a constriction, from which an upper edge section 13 is directed outwards to the upper edge 15 of the side wall 3. A narrow edge strip 16 can be seen along this.

Die Oberkante 15 ist als die Seitenwand 3 vom schmalen Randstreifen 16 trennende Perforationslinie ausgebildet, und in Abständen i von ellipsenförmigen Perforationslinien 17 unterbrochen, die ein mandelförmiges Feld F begrenzen. Knickt man den Randstreifen 16 aus der Ebene der Seitenwand 3 um einen Winkel v von ca. 90° ab, beult sich das Feld F schalenförmig ein und stabilisiert den Randbereich.The upper edge 15 is formed as a perforation line separating the side wall 3 from the narrow edge strip 16, and interrupted at intervals i by elliptical perforation lines 17 which delimit an almond-shaped field F. If the edge strip 16 is bent out of the plane of the side wall 3 by an angle v of approximately 90 °, the field F bulges like a shell and stabilizes the edge region.

Bei einem weiteren Ausführungsbeispiel nach Fig. 3 ist die Perforationslinie der Oberkante 15 von einem sechseckigen Feld S unterbrochen, dessen von der Perforationslinie 15 ausgehende Seiten 18 angestanzt sind, während die zur Perforationslinie 15 parallel verlaufenden Längslinien 19 perforiert sind. Die sechseckige Fläche S bleibt auch beim Knicken des Randstreifens 16 aus der Ebene der Seitenwand 3 i.w. eben.In a further exemplary embodiment according to FIG. 3, the perforation line of the upper edge 15 is interrupted by a hexagonal field S, the sides 18 of which are embossed from the perforation line 15, while the longitudinal lines 19 running parallel to the perforation line 15 are perforated. The hexagonal surface S remains i.w. even when the edge strip 16 is bent from the plane of the side wall 3. just.

Alle beschriebenen Teile sind gemeinsam aus einem Materialstreifen zugeschnitten, vorzugsweise aus einer Kartonschicht mit aufkaschierter Aluminiumfolie. Letztere bildet die zum Forminnenraum Q gerichtete Kontaktschicht für das nicht wiedergegebene Backgut.All the parts described are cut together from a material strip, preferably from a cardboard layer with laminated aluminum foil. The latter forms the contact layer directed towards the mold interior Q for the baked goods which are not reproduced.

Fig. 2 zeigt eine bis zu einer querliegenden Faltlinie 23 als mittlere Symmetrielinie reichende Häfte des Zuschnitts Z für die Backform 1. Außer den bereits beschriebenen Knicklinien 15, 20, 21 sind hier noch von den Backformecken E ausgehende diagonal in den Seitenwänden 3 und den Randstreifen 16 verlaufende Faltlinien 24, 25 zu erkennen, die an der Außenkante 26 des Randstreifen 16 in unterschiedlichen Abständen m, n zur Symmetrielinie 23 enden.Fig. 2 shows a half of the cut Z for the baking mold 1 reaching as far as a transverse fold line 23 as a central line of symmetry. In addition to the previously described folding lines 15, 20, 21 there are diagonally emanating from the baking mold corners E in the side walls 3 and the edge strips 16 running fold lines 24, 25 can be seen, which end at the outer edge 26 of the edge strip 16 at different distances m, n from the line of symmetry 23.

Die Knicklinien 15, 20, 21 dienen zur Herstellung der Backform 1, die Faltlinien 23 bis 25 zu deren Faltung zu einem Versandstück; der Randstreifen 16 wird in die Ebene der Seitenwand 3 gestellt und die von den diagonalen Faltlinien 24 bzw. 25 begrenzten Wandungsteile der stehenden Backform 1 in Richtung y (Fig. 1) gebogen. Die übrigen Teile der Seitenwände 3 mit den an ihnen festliegenden Stirnwänden 4 knicken dabei in Pfeilrichtung z (Fig. 2) aufeinander zu. Anschließend können beide Formhälften -- um die Symmetrielinie 23 gefaltet -- aufeinandergelegt werden.The fold lines 15, 20, 21 are used to produce the baking mold 1, the fold lines 23 to 25 for folding them into a shipping item; the edge strip 16 is placed in the plane of the side wall 3 and the wall parts of the standing baking mold 1 delimited by the diagonal folding lines 24 and 25 are bent in the direction y (FIG. 1). The remaining parts of the side walls 3 with the end walls 4 attached to them bend towards each other in the direction of the arrow z (FIG. 2). Then both mold halves - folded around the line of symmetry 23 - can be placed one on top of the other.

Bei einem in umgekehrter Folge durchgeführten Entfalten der Backform 1 in ihre Gebrauchsstellung wird die Wandstabilität durch das Ausklappen der Randstreifen 16 um etwa 90° aus der Ebene der Seitenwand 3und insbesondere die Hilfe der Feder F, S erzeugt.When the baking mold 1 is unfolded into its use position in the reverse sequence, the wall stability is produced by folding out the edge strips 16 by approximately 90 ° from the plane of the side wall 3 and in particular using the spring F, S.
