Im Bereich der Fischverpackungen aber auch bei Verpackungen für andere Lebensmittel wird zwischen Transport- und Präsentationsverpackung unterschieden. Die Transportverpackungen dienen dazu, das Lebensmittel bei der Verteilung zu den Geschäften sicher zu verpacken und zu transportieren. Die Präsentationsverpackungen dienen dazu, das Lebensmittel dem Käufer im Geschäft ansprechend zu präsentieren. Aufgrund ihres unterschiedlichen Einsatzes und ihrer unterschiedlichen Verwendungszwecke müssen Transport- und Präsentationsverpackungen unterschiedlichen Ansprüchen genügen.In the field of fish packaging but also in packaging for other foods, a distinction is made between transport and presentation packaging. The transport packaging is used to safely package and transport the food when distributed to the shops. The presentation packaging serves to present the food to the shopper in the shop in an appealing manner. Due to their different use and their different uses transport and presentation packaging must meet different requirements.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine insbesondere zur Präsentation von Lebensmitteln, wie beispielsweise von Fisch und Fischerzeugnissen geeignete Verpackung bereitzustellen, die mit einfachen Mitteln eine ansprechende Präsentation des Produkts gestattet und zugleich Beschädigungen vermeidet.The present invention has for its object to provide a suitable in particular for the presentation of food, such as fish and fish products suitable packaging that allows simple means an attractive presentation of the product and at the same time avoids damage.

Erfindungsgemäß wird die Aufgabe durch eine Verpackung mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden die Gegenstände der Unteransprüche.According to the invention the object is achieved by a package having the features of claim 1. Advantageous embodiments form the subject of the dependent claims.

Die erfindungsgemäße Verpackung besteht aus einem Schalenelement und einer Umhüllung aus Folienmaterial. Das Schalenelement besitzt ein Bodenelement und mindestens eine Seitenwand. Im verpackten Zustand umschließt das Folienmaterial das Schalenelement und hält die mindestens eine Seitenwand in einer aufgerichteten Position. In der aufgerichteten Position bildet die mindestens eine Seitenwand einen Winkel mit dem Bodenelement und ist insbesondere aus einer Hauptebene des Bodenelements herausgeneigt. Erfindungsgemäß ist die mindestens eine Seitenwand entlang einer gebogenen Faltlinie an dem Bodenelement angelenkt. Im nicht verpackten Zustand liegt das Schalenelement flach mit der oder den Seitenwänden. Ist die Umhüllung aufgebracht, so ist die Seitenwand aufgerichtet, wobei die gebogene Faltlinie ein Umknicken dieser auf das Bodenelement verhindert, so daß eine schalenförmige Verpackung entsteht. Unter einer gebogenen Faltlinie im Sinne der Erfindung wird jede nicht vollständig gerade Linie verstanden, also beispielsweise auch stückweise gerade Polygonzüge oder geknickte Abschnitte mit stückweise geradem oder gebogenem Verlauf.The packaging according to the invention consists of a shell element and a sheath made of film material. The shell element has a bottom element and at least one side wall. When packaged, the sheet material encloses the shell member and holds the at least one sidewall in an upright position. In the erected position, the at least one side wall forms an angle with the bottom element and is in particular inclined out of a main plane of the bottom element. According to the invention, the at least one side wall is articulated along a curved fold line on the bottom element. In the unpackaged state, the shell element lies flat with the side wall (s). If the wrap applied, the side wall is erect, the curved fold line prevents them from bending over on the bottom element, so that a cup-shaped packaging is formed. For the purposes of the invention, a bent fold line is understood to mean any line which is not completely straight, that is to say, for example, piecewise straight traverses or bent sections with a piecewise straight or curved course.

In einer bevorzugten Ausgestaltung sind zwei Seitenwände vorgesehen, die an gegenüberliegenden Seiten des Bodenelements angelenkt sind. Es sind aber auch Ausgestaltungen mit einer, drei oder mehr Seitenwänden möglich.In a preferred embodiment, two side walls are provided, which are articulated on opposite sides of the floor element. But there are also embodiments with one, three or more side walls possible.

Die Faltlinien der Seitenwände sind vorzugsweise zueinander entgegengesetzt gekrümmt, wobei das Bodenelement ausgehend von der Mitte der Faltlinien eine zunehmende Breite besitzt. Das Bodenelement erhält durch die gebogene Faltlinie eine taillierte Form.The fold lines of the side walls are preferably curved opposite to each other, wherein the bottom element, starting from the center of the fold lines has an increasing width. The floor element is given a waisted shape by the curved fold line.

Vorzugsweise besitzt die Faltlinie ungefähr die Form eines Kreis- oder Hyperbelbogens, wobei die Faltlinien entgegengesetzt gekrümmt einander gegenüberliegen.Preferably, the fold line is approximately in the shape of a circular or hyperbolic sheet, with the fold lines oppositely curved opposite each other.

In einer möglichen Ausgestaltung besitzt jede der Seitenwände eine entlang dem Bodenelement variierende Wandhöhe in der aufgerichteten Position. In der aufgerichteten Position befindet sich das Bodenelement unten und die Kante der Seitenwände bilden den seitlichen oberen Rand der Schale.In one possible embodiment, each of the side walls has a wall height varying along the floor element in the erected position. In the erected position, the floor element is below and the edge of the side walls form the lateral upper edge of the shell.

In einer bevorzugten Ausgestaltung besitzen die Seitenwände einen geschwungenen oberen Rand, bevorzugt mit einem Bereich größerer Wandhöhe und einem Bereich geringerer Wandhöhe. Die Bereiche jeder Seitenwand bilden bevorzugt einen wellenförmigen oberen Rand.In a preferred embodiment, the side walls have a curved upper edge, preferably with a region of greater wall height and a region of lesser wall height. The regions of each side wall preferably form a wavy upper edge.

Besonders bevorzugt sind die Seitenwände kongruent, also formgleich ausgebildet, und mit entgegengesetzter Orientierung an dem Bodenelement angeordnet, so daß der Bereich größerer Wandhöhe an einer Seitenwand dem Bereich mit geringerer Wandhöhe an der anderen Seitenwand gegenüberliegt. Bevorzugt besitzen die Seitenwände abgerundete Ecken.Particularly preferably, the side walls are congruent, that is formed with the same shape, and arranged with opposite orientation to the bottom element, so that the region of greater wall height on one side wall is opposite to the region with lower wall height on the other side wall. Preferably, the side walls have rounded corners.

Aufgrund der gebogenen Faltlinie besitzt das Bodenelement im aufgerichteten Zustand der Seitenwände eine gebogene Form, bei der die Ränder des Bodenelements zwischen den Seitenwänden angehoben sind. Mit der gebogenen Faltlinie für die Seitenelemente entsteht aus dem flachen Zuschnitt ein schalenförmiger Behälter mit zwei aufgerichteten Seitenwänden und einem gekrümmten Bodenelement.Due to the curved fold line, the bottom element in the erected state of the side walls has a curved shape in which the edges of the bottom element are raised between the side walls. The curved fold line for the side elements creates a bowl-shaped container with two raised side walls and a curved floor element.

Das Bodenelement besitzt bevorzugt jeweils einen gradlinigen Rand zwischen den Seitenwänden, die beispielsweise parallel zueinander verlaufen.The bottom element preferably has in each case a straight edge between the side walls, which extend for example parallel to one another.

Bevorzugt wird eine Schrumpffolie als Umhüllung für die erfindungsgemäße Verpackung vorgesehen. Eine Schrumpffolie übt im aufgeschrumpften Zustand eine zum Zentrum des Behälters gerichtete Kraft auf die Seitenwände aus. Normalerweise macht diese Kraft eine besondere Ausgestaltung des Zuschnitts erforderlich, damit durch die von der Schrumpffolie ausgeübte Kraft der Behälter nicht verformt wird. Bei der erfindungsgemäßen Verpackung wird die Kraft der Schrumpffolie gerade dazu ausgenutzt, um die Verpackung in der aufgerichteten Position zu halten. Die Seitenwände können aufgrund der Schrumpffolie nicht nach außen wegklappen. Ein Umklappen nach innen zu dem Bodenelement ist nicht möglich, da die Faltlinien gebogen sind und so das entsprechend verformte Bodenelement ein Umklappen nach innen verhindert.Preferably, a shrink film is provided as a wrapper for the packaging according to the invention. A shrink film exerts, in the shrunk-on state, a force directed towards the center of the container on the side walls. Normally, this force requires a special design of the blank so that the container is not deformed by the force exerted by the shrink film. In the case of the packaging according to the invention, the force of the shrink film is utilized to hold the package in the erected position. The side walls can not fold out due to the shrink film. A folding inwards to the bottom element is not possible because the fold lines are bent and thus prevents the correspondingly deformed bottom element from folding inside.

Es ist möglich, eine Einlage zur Aufnahme von Fett und/oder Flüssigkeit auf dem Bodenelement anzuordnen. Zusätzlich oder alternativ kann die Einlage das Bodenelement verstärken.It is possible to arrange an insert for receiving fat and / or liquid on the floor element. Additionally or alternatively, the insert may reinforce the floor element.

Für die Herstellung des Schalenelements bieten sich eine Reihe von unterschiedlichen Materialien an. Beispielsweise kann das Schalenelement aus Kartonmaterial, beispielsweise Papier- oder Pappmaterial hergestellt sein. Das Kartonmaterial kann mit einer entsprechenden fett- und wasserundurchlässigen Beschichtung versehen sein.For the production of the shell element to offer a number of different materials. For example, the shell element can be made of cardboard material, for example paper or cardboard material. The cardboard material may be provided with a corresponding grease and water impermeable coating.

Alternativ kann das Schalenelement auch aus einem Kunststoffmaterial hergestellt sein. Hierbei bieten sich als Kunststoffmaterial beispielsweise Polypropylen (PP) oder Polyethylen (PE) oder eine Mischung dieser Kunststoffmaterialien an. Auch ist es möglich, einen geschäumten Kunststoff als Verpackungsmaterial vorzusehen, beispielsweise Styropor® oder einen Saugvlies, der geschichtet aufgebracht an seiner Außenseite eine dichte Folie und eine perforierte Folie auf der Innenseite besitzt. Auch ist es möglich, Holz oder Holzfurnier oder Kombinationen anderer Materialien mit Holz zu verwenden.Alternatively, the shell element may also be made of a plastic material. In this case, offer as a plastic material, for example, polypropylene (PP) or polyethylene (PE) or a mixture of these plastic materials. It is also possible to provide a foamed plastic as a packaging material, for example Styrofoam® or a nonwoven fabric, which has applied layered on its outside a dense film and a perforated film on the inside. It is also possible to use wood or wood veneer or combinations of other materials with wood.

Die erfindungsgemäße Aufgabe wird ebenfalls durch ein Verfahren zum Verpacken eines Lebensmittels mit den Merkmalen aus Anspruch 26 gelöst.The object of the invention is also achieved by a method for packaging a food having the features of claim 26.

Das erfindungsgemäße Verfahren ist insbesondere für das Verpacken von Fisch und Fischerzeugnissen sowie für Frisch- und Räucherfisch geeignet. In einem ersten Verfahrensschritt wird auf einen länglichen Zuschnitt mit zwei einander gegenüberliegenden Seitenwänden das zu verpackende Lebensmittel gelegt. Die Seitenwände sind über eine gekrümmte Faltlinie mit dem Zuschnitt verbunden. Faltlinie ist hierbei wieder allgemein jegliche Linie in dem Zuschnitt, die ein Umknicken der Seitenwände erlaubt, also insbesondere auch gefalzte Linien und Rill-Linien. In einem zweiten Schritt wird bei dem erfindungsgemäßen Verfahren der Zuschnitt mit dem Lebensmittel in einen Folienschlauch eingeführt, der an Kopf- und Fußende verriegelt wird. In einem nachfolgenden Schritt wird die Folie geschrumpft, wobei die Seitenwände des Zuschnitts aufgerichtet werden und ein Bodenelement nach außen gekrümmt wird. Bei dem erfindungsgemäßen Verfahren wird das Lebensmittel auf einen flachen Zuschnitt gelegt, aus dem eine schalenförmige Verpackung gebildet wird, die eine Schrumpffolie umgibt. Vor dem Schrumpfungsvorgang liegt die Folie an den Seitenwänden an. Hierbei sind die Seitenwände leicht aufgestellt, sodass der versiegelte Folienschlauch die Seitenwände leicht aufrichtet. Folienschlauch und Faltlinien sind bei dem erfindungsgemäßen Verfahren derart dimensioniert, dass der versiegelte Folienschlauch die Seitenwände leicht aufrichtet. Bevorzugt folgt die Dimensionierung so, dass bei einer sich um 20 bis 60 % verkleinernden Schrumpffolie die Seitenwände durch die Schrumpfung aufgerichtet werden.The inventive method is particularly suitable for the packaging of fish and fish products and for fresh and smoked fish. In a first method step, the food to be packaged is placed on an elongate blank with two opposite side walls. The side walls are connected by a curved fold line with the blank. Folding line here is again generally any line in the blank, which allows a kinking of the side walls, so in particular also folded lines and creasing lines. In a second step, in the method according to the invention, the blank with the food is introduced into a film tube which is locked at the head and foot ends. In a subsequent step, the film is shrunk, the side walls of the blank are erected and a bottom member is curved outwards. In the method according to the invention, the food is placed on a flat blank, from which a cup-shaped packaging which forms a shrink film. Before the shrinking process, the film rests against the side walls. Here, the side walls are easily positioned so that the sealed film tube easily straightens the sidewalls. Film tube and fold lines are dimensioned in the inventive method such that the sealed film tube easily straightens the side walls. The dimensioning preferably follows such that when the shrinking film shrinks by 20 to 60%, the side walls are erected by the shrinkage.

Die Erfindung wird nachstehend anhand eines Ausführungsbeispiels näher erläutert.The invention will be explained in more detail below with reference to an embodiment.

Fig. 1 zeigt einen abgewickelten Zuschnitt 10 für die erfindungsgemäße Verpackung. Der Zuschnitt besitzt ein Bodenelement 12 und zwei Seitenwände 14 und 16. Die Seitenwände 14 und 16 sind über gebogene Faltlinien 18 und 20 an dem Bodenelement angelenkt, wobei die Faltlinien als Rill- oder Ritzlinien ausgebildet sein können. Fig. 1 shows a developed blank 10 for the packaging according to the invention. The blank has a bottom element 12 and two side walls 14 and 16. The side walls 14 and 16 are hinged on curved fold lines 18 and 20 on the bottom element, wherein the fold lines may be formed as a score or score lines.

Das Bodenelement 12 besitzt zwei Ränder 22 und 24, die parallel zwischen den Seitenwänden 14 und 16 verlaufen. Das Bodenelement 12 weist eine viereckige Form mit zwei parallelen graden Rändern 22 und 24 und zwei nach innen gewölbte Faltlinien 18 und 20 auf. Hierdurch erhält das Bodenelement 12 eine taillierte Form.The bottom member 12 has two edges 22 and 24 which extend parallel between the side walls 14 and 16. The bottom element 12 has a quadrangular shape with two parallel straight edges 22 and 24 and two inwardly curved fold lines 18 and 20. As a result, the bottom element 12 is given a waisted shape.

Die Seitenwände 14 und 16 sind kongruent und seitenverkehrt an unterschiedlichen Seiten des Bodenelements 12 angelenkt. Die Seitenwand 14 besitzt einen oberen Rand 22, so daß das Seitenelement eine entlang dem Bodenelement 12 variierende Höhe besitzt. In der abgewickelten Darstellung in Fig. 1 ergibt sich die Höhe der Seitenwand 14 durch den Abstand des oberen Randes 22 von der Faltlinie 18. Seitenwand 16 besitzt den gleichen Verlauf des oberen Randes 28, jedoch verläuft die Änderung der Seitenwandhöhe in entgegengesetzter Richtung zu der von Seitenwand 14. Die Verpackung besitzt nur zwei aufgerichtete Seitenwände.The side walls 14 and 16 are congruent and reversed articulated on different sides of the floor element 12. The side wall 14 has an upper edge 22 so that the side member has a varying height along the bottom member 12. In the developed representation in Fig. 1 The height of the side wall 14 results from the distance of the upper edge 22 from the fold line 18. Side wall 16 has the same course of the upper edge 28, but the change of the side wall height in the opposite direction to that of the side wall 14. The package has only two erected side walls.

Fig. 2 zeigt eine perspektivische Ansicht der Verpackung mit einer Schrumpffolie 30. Zur besseren Darstellung ist die Schrumpffolie 30 durch einige Linien angedeutet. Die Schrumpffolie ist jedoch ohne Falten, Knicke oder dergleichen auf den Zuschnitt 10 aufgeschrumpft. Wie aus Fig. 3 ersichtlich, schließen die Seitenwände 14 und 16 einen rechten Winkel mit dem Bodenelement 12 ein. Die Schrumpffolie 30 läuft um die Schale, also das Bodenelement und die Seitenwände 14 und 16. Fig. 2 shows a perspective view of the package with a shrink film 30. For clarity, the shrink film 30 is indicated by a few lines. However, the shrink film is shrunk onto the blank 10 without wrinkles, kinks or the like. How out Fig. 3 As can be seen, the side walls 14 and 16 form a right angle with the bottom element 12. The shrink film 30 runs around the shell, so the bottom member and the side walls 14 and 16.

In Fig. 2 ist eine Hilfslinie A eingezeichnet, die eine Ablagefläche für die Verpackung andeutet. Deutlich erkennbar ist, daß die Verpackung entlang der Kanten 22 und 24 von dem Untergrund um die Höhe h beabstandet ist. Der Abstand h hängt von der Krümmung der Faltlinien 18 und 22 ab. Durch das Anheben der Ränder 22 und 24 bildet das Bodenelement 12 eine wannenartige Aufnehmung für den zu verpackenden Fisch oder die Fischerzeugnisse (nicht dargestellt).In Fig. 2 An auxiliary line A is drawn in, which indicates a storage area for the packaging. It can clearly be seen that the packaging along the edges 22 and 24 is spaced from the ground by the height h. The distance h depends on the curvature of the fold lines 18 and 22. By raising the edges 22 and 24, the bottom member 12 forms a trough-like Aufnehmung for the fish or fish products to be packaged (not shown).

Auf das Bodenelement 12 kann eine Aufnahme zur Absorption von Wasser und/oder Fett vorgesehen sein, die beispielsweise aus einem beschichteten Vliesmaterial besteht. Auch ist es möglich, in das Bodenelement 12 eine zusätzliche Verstärkungseinlage einzulegen, die das Bodenelement verstärkt.On the bottom element 12, a receptacle for absorbing water and / or fat may be provided, which consists for example of a coated nonwoven material. It is also possible to insert an additional reinforcing insert into the bottom element 12, which reinforces the bottom element.

Die Verpackung kann abhängig von dem zu verpackenden Fisch oder Fischerzeugnis aus unterschiedlichen Materialien bestehen. Beispielsweise kann für die Verpackung von Räucherfisch eine Pappe verwendet werden, die zusätzlich mit einer fett- und wasserundurchlässigen Schicht versehen ist. Für die Verpackung von Frischfisch kann eine Schale aus PP oder ein Kunststoffschaummaterial, beispielsweise aus Styropor®, vorgesehen sein.The packaging may be made of different materials depending on the fish or fish product to be packaged. For example, can be used for the packaging of smoked fish, a cardboard, which is additionally provided with a grease and water impermeable layer. For the packaging of fresh fish, a shell of PP or a plastic foam material, for example made of Styrofoam®, can be provided.

Figur 4 zeigt schematisch eine Ansicht des Verpackungsvorgangs. In einem ersten Schritt 32 wird der flache Zuschnitt 10 zugeführt, der zu verpackende Fisch auf das Bodenelement 12 gelegt. Das Schalenelement 10 kann mit einem saugfähigen Vliesmaterial ausgestattet sein. Dies kann entweder - bevor der Fisch auf das Schalenelement gelegt wird - separat darauf gelegt werden oder mit dem Schalenelement verklebt sein. In einer zweiten Stufe 34 wird das Schalenelement in einen Folienschlauch eingeführt und an Kopf- und Fußende verschweißt. Der Umfang des Folienschlauchs, der um die Verpackung gelegt wird, ist auf die Falztiefe, das Endvolumen der Verpackung und die Gasmenge der Schutzgasatmosphäre abgestimmt. Das Folienmaterial kann entweder bereits als geschlossener Folienschlauch zur Verfügung stehen, oder als eine Folienbahn, die entlang der Längsrichtung zu einem Schlauch geschlossen wird. Der so gebildete Folienbeutel wird in Schritt 34 vor dem Versiegeln mit einer Schutzgasatmosphäre gefüllt. Der fertige Beutel 36 gelangt nachfolgend in einen Schrumpftunnel 38. In dem Schrumpftunnel ist Durchlaufgeschwindigkeit und Temperatur so abgestimmt, dass der Folienbeutel 36 auf das gewünschte Endvolumen schrumpft. Die Folienbeschaffenheit ist hierbei so gewählt, dass die Folie um 40 bis 60 % schrumpft. Die Falztiefe der Faltlinie ist hierbei abhängig vom verwendeten Material entsprechend gewählt. Das Aufrichten der Seitenwände erfolgt in dem Schrumpftunnel 38 mit Zusammenziehen der Schrumpffolie. FIG. 4 shows schematically a view of the packaging process. In a first step 32, the flat blank 10 is fed, placed the fish to be packaged on the bottom element 12. The shell member 10 may be provided with an absorbent nonwoven material. This can be done either separately - before the fish is placed on the shell element - or glued to the shell element. In a second stage 34, the shell element is inserted into a film tube and welded to the head and foot ends. The circumference of the film tube, which is placed around the packaging, is adapted to the rebate depth, the final volume of the packaging and the amount of gas in the protective gas atmosphere. The film material can either already be available as a closed film tube, or as a film web which is closed along the longitudinal direction to form a tube. The film bag thus formed is filled in step 34 before sealing with a protective gas atmosphere. The finished bag 36 subsequently enters a shrink tunnel 38. In the shrink tunnel, the throughput speed and temperature are adjusted so that the film bag 36 shrinks to the desired final volume. The film quality is chosen so that the film shrinks by 40 to 60%. The rebate depth of the fold line is chosen as a function of the material used. The erecting of the side walls takes place in the shrink tunnel 38 with contraction of the shrink film.

Das Zusammenspiel zwischen Faltstärke und Schrumpffolie wird anhand der nachfolgenden Figuren näher erläutert.The interaction between folding thickness and shrink film will be explained in more detail with reference to the following figures.

Figur 5 a zeigt einen Querschnitt durch das nicht aufgerichtete Schalenelement mit dem Bodenelement 12 und den Seitenwänden 14 und 16. Wie aus der eingekreisten Detailansicht kenntlich, wurde hierfür die Faltlinien 18 und 20 eine Rilltiefe von einem Drittel der Materialstärke gewählt. Figuren 5b und c zeigen das Ergebnis bei dieser Rilltiefe: Die von der Schrumpffolie 30 ausgeübte Kraft ist nicht ausreichend, um die Seitenwände 14 und 16 vollständig aufzurichten. Der durch die Faltlinien ausgeübte Widerstand ist zu groß. Wie auch in Figur 5c ersichtlich, bilden sich nach außen geneigte Seitenwände. FIG. 5 Figure a shows a cross-section through the unripened shell element with the bottom element 12 and side walls 14 and 16. As seen in the circled detail view recognizable, this was the folding lines 18 and 20 chosen a groove depth of one third of the material thickness. FIGS. 5b and c show the result at this groove depth: The force exerted by the shrink film 30 is insufficient to fully erect the sidewalls 14 and 16. The resistance exerted by the fold lines is too large. As well as in FIG. 5c can be seen, form outwardly inclined side walls.

Figuren 6a bis 6c zeigen den umgekehrten Fall, indem eine Rilltiefe von ungefähr zwei Drittel der Materialstärke gewählt wurde. Die zu große Rilltiefe, ungefähr zwei Drittel der Materialstärke, führt zu einer zu schwachen Gegenkraft durch die Seitenwände, sodass die Schrumpffolie die Seitenwände nach innen neigt (vergl. Figur 6 c). FIGS. 6a to 6c show the opposite case by choosing a groove depth of about two thirds of the material thickness. The too large groove depth, about two-thirds of the material thickness, leads to a weak counterforce through the side walls, so that the shrink film tends the side walls inward (see FIG. FIG. 6c) ,

Figuren 7a bis 7c zeigen die erfindungsgemäße Ausgestaltung, bei der die Rilltiefe ungefähr die Hälfte der Materialstärke beträgt. Mit dieser Rilltiefe wird erreicht, dass sich bei der Verarbeitung die Seiten im wesentlichen aufrecht aufstellen. FIGS. 7a to 7c show the embodiment of the invention, in which the groove depth is approximately half the material thickness. This groove depth ensures that the sides are essentially erect during processing.
