Definitions
- the invention relates to a hinged lid box for transporting salad, vegetables, mushrooms, potatoes, rice, noodles or other side dishes.
- Disposable containers for salads, vegetables, mushrooms, potatoes, rice, noodles or other side dishes are required for delivery services, take-away sales in restaurants and in fast-food system catering.
- trays made of plastic e.g. PE, PP, PET, PS
- PLA containers are relatively expensive.
- salad bowls or cups made of cardboard are known which, like ice cream cups, are formed with a peripheral side wall, a bottom wall which is glued in place and a beaded edge. These are relatively expensive to produce.
- clamshell boxes also called “burger boxes” are used for salads, which have two shell parts hinged together about a fold line and interlockable at the front edge. Clamshell boxes are also relatively expensive to manufacture. In addition, the filling of the boxes with small-sized product is limited due to the division into two halves.
- the object of the invention is to create a container for salad, vegetables, mushrooms, potatoes, rice, noodles or other side dishes that is easy to fill and close, can be produced in large quantities with little effort and is easier to recycle.
- the object is achieved by a hinged lid box having the features of claim 1.
- Advantageous embodiments of the hinged-lid box are specified in the dependent claims.
- the hinged lid box according to the invention comprises:
- a hinged lid with o a top wall with a polygonal base area, which is connected to the top edge of a side wall on a side edge via an upper fold line, and o at least one tuck-in flap, which is connected to a side edge of the top wall via a side fold line, whereby when folded into the opening between the upper edges of the side walls dust flaps of the hinged lid can be folded over the opening and with the at least one insertion flap between the Side wall with the free edge and the dust flaps of the two adjacent side walls can be inserted.
- the dust flaps are first folded into the opening between the upper edges of the side walls.
- the curved upper edges of the side walls guide the hinged cover when the opening is closed, so that it can be better inserted with the insertion flap into the gap between the two dust flaps of the adjacent side walls and the side wall arranged in between.
- the folding box can be securely closed by inserting the tuck-in flap between the dust flaps and the side wall arranged between them, without the need for gluing or any other security measure.
- small pieces of product can be held back by the dust flaps folded into the opening until the hinged lid is closed. This also simplifies the packaging process.
- the folding box makes better use of space, since it can be filled up to the top edge and the hinged lid can be folded onto the filled product.
- Another advantage is that due to the curvature of the upper edges of the side walls, the hinged lid is curved upwards in the center, so that more product can be accommodated there than in the edge areas, which is also advantageous for filling and closing the folding box and for space utilization .
- the closed folding box has a slight inward curvature on the side walls with the dust flaps due to the curved fold lines, so that condensation water can run off better from the hinged lid boxes that are stacked or stored close together or are transported away by air passing by can be. Before use, a large number of hinged lid boxes can be stacked (nested) into one another to save space for transport and storage.
- the number of corners of the bases of the bottom wall and top wall is preferably identical in order to completely cover the opening between the upper edges of the side walls. Because the side walls slope outwardly, it is preferred that the footprint of the top wall is larger than the footprint of the bottom wall to completely cover the opening.
- the carton is said to be square, if the bases have six corners, it is hexagonal, etc.
- the side wall opposite the side wall whose upper edge is connected to the hinged lid has an upper edge designed as a free edge and has the top wall at the lateral edge which, when the hinged lid is closed, to the upper edge of this side wall adjacent, a tuck-in flap.
- a square folding box can be formed.
- the side wall opposite the side wall to which the hinged lid is hinged has an upwardly curved upper edge which is connected to a dust flap by an upwardly curved upper fold line
- the two side walls adjacent to this side wall have each have an upper edge designed as a free edge and the cover wall is connected to the lateral edges, which adjoin the upper edges of these two side walls when the hinged lid is closed, with insertion tabs.
- the two side walls adjacent to the side wall have those at the top edge with the hinged lid connected, has upwardly curved upper edges which are connected to dust flaps via upwardly curved fold lines.
- the gaps into which the two tuck-in tabs are inserted are arranged on both sides next to the side wall that is opposite the side wall to which the hinged lid is articulated. In this way it can be achieved that the hinged cover closes particularly tightly.
- a hexagonal folding box, for example, can be formed in this way.
- the upper edges of the side panels that are not connected to a dust flap by a top fold line are rectilinear.
- the upper fold line, via which the hinged lid is connected to a side wall is straight, which makes it easier to fold the hinged lid.
- the edges of the side walls, designed as free edges, on which the tuck-in tabs can be anchored are straight, which makes it easier to close the hinged lid.
- the lateral edges of the top wall which adjoin rectilinear upper edges of side walls when the hinged lid is closed, are also rectilinear. Furthermore, the lateral edges of the top wall, which adjoin curved upper edges of side walls when the hinged lid is closed, are as convexly curved as the side walls after the dust flaps have been folded into the opening.
- the folded triangular flaps are each folded against the outside of a side wall and glued to it. This enables an interior with smooth side walls, which makes it easier to remove product. Furthermore, the creation and gluing of the Triangular flaps on the outside of the side walls are advantageous for automatically erecting and gluing the folding box.
- two sets of folded together triangular flaps are folded against the same side wall. This is also advantageous for the automatic erecting and gluing of the folding box.
- two sets of folded together triangular flaps are each folded against side panels that are not connected to a dust flap by a curved fold line at the curved top edge. Because the side panels do not have a curved edge with a dust tab hinged to them, they do not curve when erected, but remain flat, making it easier to apply and tape down the triangular tabs.
- the triangular flaps are folded against side walls which are connected to the hinged cover at the top edge via an upper fold line and which have an upper edge designed as a free edge. These side walls are additionally stabilized by the counter-folded and glued triangular flaps. This is advantageous for closing and holding the hinged lid in the closed position.
- the folding box is formed from a one-piece blank that can be folded flat. This is advantageous for production with the lowest possible use of material.
- Fig. 1 shows a blank for producing the folding box lying flat in a
- Fig. 2 a folding box formed from the blank with opened
- Fig. 3 shows the folding box at the beginning of the closing of the hinged lid in a
- Hinged lid in a perspective view from the opposite side
- FIG. 6 shows the closed folding box in a perspective view obliquely from above and from the side
- the information "below”, “above” and derived information such as “below” and “above” refer to the erected folding box, with the base wall being aligned horizontally and the side walls extending upwards from the base wall.
- the blank 1 has a bottom wall 2 with a hexagonal base area, with a side wall 9, 10, 11, 12, 13, 14 is articulated.
- the side walls 9, 10, 11, 12, 13, 14 are each trapezoidal, with their width increasing slightly from bottom to top.
- the lateral edges of adjacent side walls 9, 10, 11, 12, 13, 14 are connected to one another via corner joints 15, 16, 17, 18, 19, 20.
- Each corner connection 15 to 20 consists of two triangular flaps 15.1, 15.2 to 20.1, 20.2, which are connected to one another via central fold lines 21.1 to 26.1 and on which each one has a lateral edge of one of the two adjacent ones via an outer fold line 21.2, 21.3 to 26.2, 26.3 Side walls 9 to 14 is connected.
- the side wall 9 is connected via a straight upper fold line 27 to a hinged lid 28 which has a top wall 29 also with a hexagonal base.
- the top wall 29 has two concave lateral edges 30, 31, each of which extends to a corner of the base area. Adjacent to this, the top wall 29 has two straight lateral edges on both sides, which extend to the next corner.
- a tuck-in flap 34, 35 is articulated on each of these lateral edges via a lateral fold line 32, 33. The two outer corners of each tuck-in flap 34, 35 have curves.
- the top wall 29 Opposite the lateral edge with which the top wall 29 is hinged to the side wall 9 via the upper fold line 27, the top wall 29 has a concavely curved lateral edge 36 which extends between the two straight lateral edges with the insertion flaps 34, 35.
- the two adjoining side walls 10, 14 On both sides next to the side wall 9, which is connected to the hinged lid via the upper fold line 27, the two adjoining side walls 10, 14 have a convexly curved upper edge 37, 38, on which a dust flap is attached via a convexly curved upper fold line 39, 40 41, 42 is articulated.
- the side wall 12, which is arranged opposite the side wall 9, which is connected to the hinged lid 28 via an upper fold line 27, is also connected at the upper edge 43 via a convexly curved upper fold line 44 to a dust flap 45.
- each dust flap 41, 42, 45 is also rounded.
- the folding box 48 is erected by folding the triangular flaps 15.1, 15.2 to 20.1, 20.2 of each corner connection 15 to 20 around the middle fold lines 21.1 to 26.1 against each other and against the outside of a side wall 9, 11, 13 and gluing them upper edge is straight.

Die Erfindung betrifft eine Klappdeckelschachtel zum Transportieren von Salat, Gemüse, Pilzen, Kartoffeln, Reis, Nudeln oder anderen Beilagen. The invention relates to a hinged lid box for transporting salad, vegetables, mushrooms, potatoes, rice, noodles or other side dishes.
Beim Lieferservice, Außer-Haus-Verkauf von Restaurants und in der Fastfood- Systemgastronomie werden Einwegbehältnisse für Salate, Gemüse, Pilze, Kartoffeln, Reis, Nudeln oder andere Beilagen benötigt. Bekannt ist die Verwendung von Schalen aus Kunststoff (z.B. PE, PP, PET, PS), die nach Gebrauch im Restmüll entsorgt werden müssen. Ferner bekannt sind kompostierbare Einwegschalen oder -becher für Salat oder Feinkost aus Polyactiden (PLA). Behältnisse aus PLA sind relativ teuer. Darüber hinaus sind Salatschalen oder -becher aus Karton bekannt, die ähnlich wie Eisbecher mit einer umlaufenden Seitenwand einer eingeklebten Bodenwand und einem umgebördelten Rand gebildet sind. Diese sind in der Herstellung verhältnismäßig aufwendig. Ferner werden für Salate sog. Clamshell-Schachteln (auch „Burger-Boxen“ genannt) benutzt, die zwei um eine Faltlinie aneinandergelenkte und an der Vorderkante miteinander verriegelbare Schalenteile aufweisen. Clamshell-Boxen sind ebenfalls in der Herstellung verhältnismäßig aufwendig. Darüber hinaus ist die Befüllung der Boxen mit kleinstückigem Produkt aufgrund der Teilung in zwei Hälften begrenzt. Disposable containers for salads, vegetables, mushrooms, potatoes, rice, noodles or other side dishes are required for delivery services, take-away sales in restaurants and in fast-food system catering. The use of trays made of plastic (e.g. PE, PP, PET, PS), which have to be disposed of in the residual waste after use, is known. Also known are compostable disposable bowls or cups for salad or delicatessen made from polyactides (PLA). PLA containers are relatively expensive. In addition, salad bowls or cups made of cardboard are known which, like ice cream cups, are formed with a peripheral side wall, a bottom wall which is glued in place and a beaded edge. These are relatively expensive to produce. Furthermore, so-called clamshell boxes (also called “burger boxes”) are used for salads, which have two shell parts hinged together about a fold line and interlockable at the front edge. Clamshell boxes are also relatively expensive to manufacture. In addition, the filling of the boxes with small-sized product is limited due to the division into two halves.
Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Behälter für Salat, Gemüse, Pilze, Kartoffeln, Reis, Nudeln oder andere Beilagen zu schaffen, der leicht befüllbar und schließbar, mit geringem Aufwand in großen Mengen herstellbar und der besser wiederverwertbar ist. Proceeding from this, the object of the invention is to create a container for salad, vegetables, mushrooms, potatoes, rice, noodles or other side dishes that is easy to fill and close, can be produced in large quantities with little effort and is easier to recycle.
Die Aufgabe wird durch eine Klappdeckel Schachtel mit den Merkmalen von Anspruch 1 gelöst. Vorteilhafte Ausführungsarten der Klappdeckelschachtel sind in Unteransprüchen angegeben.
Die erfindungsgemäße Klappdeckelschachtel umfasst: The object is achieved by a hinged lid box having the features of claim 1. Advantageous embodiments of the hinged-lid box are specified in the dependent claims. The hinged lid box according to the invention comprises:
• ein Unterteil mit o einer Bodenwand mit mehreckiger Grundfläche, o nach außen geneigten Seitenwänden, die über untere Faltlinien mit den seitlichen Rändern der Bodenwand verbunden sind, o Eckverbindungen zwischen benachbarten Seitenwänden in Form von jeweils zwei Dreieckslaschen, die über eine mittlere Faltlinie miteinander verbunden sind und von denen jede über eine äußere Faltlinie mit einem seitlichen Rand einer der beiden benachbarten Seitenwände verbunden ist, wobei die Dreieckslaschen und die mittlere Faltlinie gegeneinander und gegen eine der beiden benachbarten Seitenwände gefaltet und mit diesen verklebt sind, o Staublaschen, die über nach oben gekrümmte obere Faltlinien mit nach oben gekrümmten oberen Rändern von Seiten wänden verbunden sind, und o mindestens eine Seitenwand, deren oberer Rand eine freie Kante ist und die zwischen zwei benachbarten Seitenwänden angeordnet ist, deren obere Ränder mit Staublaschen verbunden sind,• a bottom part with o a bottom wall with a polygonal base, o outwardly inclined side walls, which are connected to the side edges of the bottom wall via lower fold lines, o corner connections between adjacent side walls in the form of two triangular flaps, which are connected to one another via a central fold line and each of which is connected by an outer fold line to a lateral edge of one of the two adjacent side panels, the triangular flaps and the central fold line being folded against one another and against one of the two adjacent side panels and glued thereto, o dust flaps, which over upturned top fold lines are connected to upwardly curved top edges of side panels, and o at least one side panel, the top edge of which is a free edge and which is arranged between two adjacent side panels, the top edges of which are connected to dust flaps,
• einen Klappdeckel mit o einer Deckwand mit mehreckiger Grundfläche, die an einem seitlichen Rand über eine obere Faltlinie mit dem oberen Rand einer Seiten wand verbunden ist, und o mindestens ein Einstecklasche, die über eine seitliche Faltlinie mit einem seitlichen Rand der Deckwand verbunden ist, wodurch bei in die Öffnung zwischen den oberen Rändern der Seitenwände gefalteten Staublaschen der Klappdeckel über die Öffnung faltbar und mit der mindestens einen Einstecklasche zwischen die
Seitenwand mit der freien Kante und die Staublaschen der beiden benachbarten Seitenwände einsteckbar ist. • a hinged lid with o a top wall with a polygonal base area, which is connected to the top edge of a side wall on a side edge via an upper fold line, and o at least one tuck-in flap, which is connected to a side edge of the top wall via a side fold line, whereby when folded into the opening between the upper edges of the side walls dust flaps of the hinged lid can be folded over the opening and with the at least one insertion flap between the Side wall with the free edge and the dust flaps of the two adjacent side walls can be inserted.
Zum Schließen der Faltschachtel werden zunächst die Staublaschen in die Öffnung zwischen den oberen Rändern der Seitenwände gefaltet. Durch die gekrümmten oberen Ränder der Seitenwände wird der Klappdeckel beim Schließen der Öffnung geführt, sodass er mit der Einstecklasche besser in die Spalte zwischen den beiden Staublaschen der benachbarten Seitenwände und der dazwischen angeordneten Seitenwand einführbar ist. Hierdurch wird das Schließen der Klappdeckelschachtel von Hand und damit das Verpacken des Produktes für die Abgabe an den Abnehmer erleichtert. Die Faltschachtel ist durch Einstecken der Einstecklasche zwischen den Staublaschen und die dazwischen angeordnete Seitenwand sicher verschließbar, ohne dass es einer Verklebung oder einer weiteren Sicherungsmaßnahme bedarf. Zudem kann kleinstückiges Produkt durch die in die Öffnung geklappten Staublaschen zurückgehalten werden, bis der Klappdeckel geschlossen ist. Auch dies vereinfacht den Verpackungsvorgang. Gegenüber den bekannten Clamshell- Faltschachteln hat die Faltschachtel eine bessere Raumausnutzung, da sie bis zum oberen Rand befüllt und der Klappdeckel auf das eingefüllte Produkt gefaltet werden kann. Ein weiterer Vorteil besteht darin, dass aufgrund der Krümmung der oberen Ränder der Seitenwände der Klappdeckel im Zentrum nach oben gewölbt ist, sodass dort mehr Produkt als in den Randbereichen untergebracht werden kann, was ebenfalls vorteilhaft für das Befüllen und Schließen der Faltschachtel und die Raumausnutzung ist. Die geschlossene Faltschachtel weist zusätzlich zu dem nach oben gewölbten Klappdeckel an den Seitenwänden mit den Staublaschen aufgrund der gekrümmten Faltlinien eine leichte Wölbung nach innen auf, sodass von den gestapelten bzw. eng nebeneinander gelagerten Klappdeckelschachteln Kondenswasser besser ablaufen bzw. durch vorbei streichende Luft abtransportiert
werden kann. Vor dem Gebrauch kann eine Vielzahl Klappdeckel schachteln für Transport und Lagerung platzsparend ineinandergestapelt (genestet) werden. To close the folding box, the dust flaps are first folded into the opening between the upper edges of the side walls. The curved upper edges of the side walls guide the hinged cover when the opening is closed, so that it can be better inserted with the insertion flap into the gap between the two dust flaps of the adjacent side walls and the side wall arranged in between. This makes it easier to close the hinged lid box by hand and thus to pack the product for delivery to the customer. The folding box can be securely closed by inserting the tuck-in flap between the dust flaps and the side wall arranged between them, without the need for gluing or any other security measure. In addition, small pieces of product can be held back by the dust flaps folded into the opening until the hinged lid is closed. This also simplifies the packaging process. Compared to the well-known clamshell folding boxes, the folding box makes better use of space, since it can be filled up to the top edge and the hinged lid can be folded onto the filled product. Another advantage is that due to the curvature of the upper edges of the side walls, the hinged lid is curved upwards in the center, so that more product can be accommodated there than in the edge areas, which is also advantageous for filling and closing the folding box and for space utilization . In addition to the upwardly curved hinged lid, the closed folding box has a slight inward curvature on the side walls with the dust flaps due to the curved fold lines, so that condensation water can run off better from the hinged lid boxes that are stacked or stored close together or are transported away by air passing by can be. Before use, a large number of hinged lid boxes can be stacked (nested) into one another to save space for transport and storage.
Die Eckenzahl der Grundflächen von Bodenwand und Deckwand ist vorzugsweise identisch, um eine die Öffnung zwischen den oberen Rändern der Seitenwände vollständig abzudecken. Da die Seitenwände nach außen geneigt sind, ist vorzugsweise die Grundfläche der Deckwand größer als die Grundfläche der Bodenwand, um die Öffnung vollständig abzudecken. The number of corners of the bases of the bottom wall and top wall is preferably identical in order to completely cover the opening between the upper edges of the side walls. Because the side walls slope outwardly, it is preferred that the footprint of the top wall is larger than the footprint of the bottom wall to completely cover the opening.
Wenn die Grundflächen vier Ecken haben, wird die Faltschachtel als viereckig bezeichnet, wenn die Grundflächen sechs Ecken haben, als sechseckig usw. If the bases have four corners, the carton is said to be square, if the bases have six corners, it is hexagonal, etc.
Gemäß einer Ausführungsart der Erfindung weist die Seitenwand, die der Seitenwand gegenüberliegt, deren oberer Rand mit dem Klappdeckel verbunden ist, einen als freie Kante ausgebildeten oberen Rand auf und weist die Deckwand an dem seitlichen Rand, der bei geschlossenem Klappdeckel an den oberen Rand dieser Seitenwand angrenzt, eine Einstecklasche auf. In dieser Weise kann insbesondere eine viereckige Faltschachtel ausgebildet sein. According to one embodiment of the invention, the side wall opposite the side wall whose upper edge is connected to the hinged lid has an upper edge designed as a free edge and has the top wall at the lateral edge which, when the hinged lid is closed, to the upper edge of this side wall adjacent, a tuck-in flap. In this way, in particular, a square folding box can be formed.
Gemäß einer weiteren Ausführungsart weist die Seitenwand, die der Seitenwand gegenüberliegt, an die der Klappdeckel angelenkt ist, einen nach oben gekrümmten oberen Rand auf, der über eine nach oben gekrümmte obere Faltlinie mit einer Staublasche verbunden ist, weisen die zu dieser Seitenwand benachbarten beiden Seitenwände jeweils einen als freie Kante ausgebildeten oberen Rand auf und ist die Deckwand an den seitlichen Rändern, die bei geschlossenem Klappdeckel an die oberen Ränder dieser beiden Seitenwände angrenzen, mit Einstecklaschen verbunden. Gemäß einer weiteren Ausführungsart weisen die beiden Seitenwände, die der Seitenwand benachbart sind, die am oberen Rand mit dem Klappdeckel
verbunden ist, nach oben gekrümmte obere Ränder auf, die über nach oben gekrümmte Faltlinien mit Staublaschen verbunden sind. Hierdurch ist der Klappdeckel mittels zweier Einstecklaschen in geschlossener Stellung verriegelbar. Die Spalte, in die die beiden Einstecklaschen hierbei eingesteckt werden, sind beidseitig neben der Seitenwand angeordnet, die der Seitenwand gegenüberliegt, an die der Klappdeckel angelenkt ist. Hierdurch kann erreicht werden, dass der Klappdeckel besonders dicht abschließt. In dieser Weise kann beispielsweise eine sechseckige Faltschachtel ausgebildet sein. According to another embodiment, the side wall opposite the side wall to which the hinged lid is hinged has an upwardly curved upper edge which is connected to a dust flap by an upwardly curved upper fold line, the two side walls adjacent to this side wall have each have an upper edge designed as a free edge and the cover wall is connected to the lateral edges, which adjoin the upper edges of these two side walls when the hinged lid is closed, with insertion tabs. According to another embodiment, the two side walls adjacent to the side wall have those at the top edge with the hinged lid connected, has upwardly curved upper edges which are connected to dust flaps via upwardly curved fold lines. As a result, the hinged cover can be locked in the closed position by means of two push-in tabs. The gaps into which the two tuck-in tabs are inserted are arranged on both sides next to the side wall that is opposite the side wall to which the hinged lid is articulated. In this way it can be achieved that the hinged cover closes particularly tightly. A hexagonal folding box, for example, can be formed in this way.
Gemäß einer weiteren Ausführungsart sind die oberen Ränder der Seitenwände, die nicht über eine obere Faltlinie mit einer Staublasche verbunden sind, geradlinig. Insbesondere ist die obere Faltlinie, über die der Klappdeckel mit einer Seitenwand verbunden ist, geradlinig, wodurch das Klappen des Klappdeckels erleichtert wird. Ferner sind die als freie Kanten ausgebildeten Ränder der Seitenwände, an denen die Einstecklaschen verankert werden können, geradlinig, wodurch das Schließen des Klappdeckels erleichtert wird. According to another embodiment, the upper edges of the side panels that are not connected to a dust flap by a top fold line are rectilinear. In particular, the upper fold line, via which the hinged lid is connected to a side wall, is straight, which makes it easier to fold the hinged lid. Furthermore, the edges of the side walls, designed as free edges, on which the tuck-in tabs can be anchored, are straight, which makes it easier to close the hinged lid.
Gemäß einer weiteren Ausführungsart sind die seitlichen Ränder der Deckwand, die bei geschlossenem Klappdeckel an geradlinige obere Ränder von Seitenwänden angrenzen, ebenfalls geradlinig. Ferner sind die seitlichen Ränder der Deckwand, die bei geschlossenem Klappdeckel an gekrümmte obere Ränder von Seitenwänden angrenzen, so konvex gekrümmt, wie die Seitenwände nach dem Falten der Staublaschen in die Öffnung. According to a further embodiment, the lateral edges of the top wall, which adjoin rectilinear upper edges of side walls when the hinged lid is closed, are also rectilinear. Furthermore, the lateral edges of the top wall, which adjoin curved upper edges of side walls when the hinged lid is closed, are as convexly curved as the side walls after the dust flaps have been folded into the opening.
Gemäß einer weiteren Ausführungsart sind die zusammengefalteten Dreieckslaschen jeweils gegen die Außenseite einer Seitenwand gefaltet und mit dieser verklebt. Hierdurch wird ein Innenraum mit glatten Seitenwänden ermöglicht, wodurch die Entnahme von Produkt erleichtert wird. Ferner ist das Anlegen und Verkleben der
Dreieckslaschen mit den Außenseiten der Seitenwände für ein automatisches Aufrichten und Kleben der Faltschachtel von Vorteil. According to a further embodiment, the folded triangular flaps are each folded against the outside of a side wall and glued to it. This enables an interior with smooth side walls, which makes it easier to remove product. Furthermore, the creation and gluing of the Triangular flaps on the outside of the side walls are advantageous for automatically erecting and gluing the folding box.
Gemäß einer weiteren Ausführungsart sind jeweils zwei Anordnungen aus zusammengefalteten Dreieckslaschen gegen dieselbe Seitenwand gefaltet. Auch dies ist vorteilhaft für das automatische Aufrichten und Kleben der Faltschachtel. According to a further embodiment, two sets of folded together triangular flaps are folded against the same side wall. This is also advantageous for the automatic erecting and gluing of the folding box.
Gemäß einer weiteren Ausführungsart sind jeweils zwei Anordnungen aus zusammengefalteten Dreieckslaschen gegen Seitenwände gefaltet, die nicht über eine gekrümmte Faltlinie am gekrümmten oberen Rand mit einer Staublasche verbunden sind. Da die Seitenwände keinen gekrümmten Rand mit einer daran angelenkten Staublasche haben, werden sie beim Aufrichten nicht gekrümmt, sondern bleiben plan, wodurch das Anlegen und Festkleben der Dreieckslaschen vereinfacht wird. Gemäß einer weiteren Ausführungsart sind die Dreieckslaschen gegen Seitenwände gefaltet, die am oberen Rand über eine obere Faltlinie mit dem Klappdeckel verbunden sind und die einen als freie Kante ausgebildeten oberen Rand aufweisen. Durch die gegengefalteten und festgeklebten Dreieckslaschen werden diese Seitenwände zusätzlich stabilisiert. Dies ist für das Schließen und Festhalten des Klappdeckels in der geschlossenen Stellung von Vorteil. According to another embodiment, two sets of folded together triangular flaps are each folded against side panels that are not connected to a dust flap by a curved fold line at the curved top edge. Because the side panels do not have a curved edge with a dust tab hinged to them, they do not curve when erected, but remain flat, making it easier to apply and tape down the triangular tabs. According to a further embodiment, the triangular flaps are folded against side walls which are connected to the hinged cover at the top edge via an upper fold line and which have an upper edge designed as a free edge. These side walls are additionally stabilized by the counter-folded and glued triangular flaps. This is advantageous for closing and holding the hinged lid in the closed position.
Gemäß einer weiteren Ausführungsart wird die Faltschachtel aus einem einteiligen Zuschnitt faltbaren Flachmaterial gebildet. Dies ist für die Herstellung mit möglichst geringem Materialeinsatz vorteilhaft. According to a further embodiment, the folding box is formed from a one-piece blank that can be folded flat. This is advantageous for production with the lowest possible use of material.
Die Erfindung wird nachfolgend anhand der anliegenden Zeichnungen eines Ausführungsbeispieles näher erläutert. In den Zeichnungen zeigen:

Die Angaben „unten“, „oben“ und davon abgeleitete Angaben wie „unterhalb“ und „oberhalb“ beziehen sich auf die aufgerichtete Faltschachtel, wobei die Bodenwand horizontal ausgerichtet ist und sich die Seitenwände von der Bodenwand ausgehend nach oben erstrecken. The information "below", "above" and derived information such as "below" and "above" refer to the erected folding box, with the base wall being aligned horizontally and the side walls extending upwards from the base wall.
Gemäß Fig. 1 weist der Zuschnitt 1 eine Bodenwand 2 mit sechseckiger Grundfläche auf, wobei an jeden seitlichen Rand der Bodenwand 2 über eine geradlinige untere Faltlinie 3, 4, 5, 6, 7, 8 eine Seitenwand 9, 10, 11, 12, 13, 14 angelenkt ist. Die Seitenwände 9, 10, 11, 12, 13, 14 sind jeweils trapezförmig, wobei sich ihre Breite von unten nach oben etwas vergrößert.
Die seitlichen Ränder benachbarter Seitenwände 9, 10, 11, 12, 13, 14 sind über Eckverbindungen 15, 16, 17, 18, 19, 20 miteinander verbunden. Jede Eckverbindung 15 bis 20 besteht aus zwei Dreieckslaschen 15.1, 15.2 bis 20.1, 20.2, die über mittlere Faltlinien 21.1 bis 26.1 miteinander verbunden sind und an denen jede über eine äußere Faltlinie 21.2, 21.3 bis 26.2, 26.3 mit einem seitlichen Rand einer der beiden benachbarten Seitenwände 9 bis 14 verbunden ist. According to FIG. 1, the blank 1 has a bottom wall 2 with a hexagonal base area, with a side wall 9, 10, 11, 12, 13, 14 is articulated. The side walls 9, 10, 11, 12, 13, 14 are each trapezoidal, with their width increasing slightly from bottom to top. The lateral edges of adjacent side walls 9, 10, 11, 12, 13, 14 are connected to one another via corner joints 15, 16, 17, 18, 19, 20. Each corner connection 15 to 20 consists of two triangular flaps 15.1, 15.2 to 20.1, 20.2, which are connected to one another via central fold lines 21.1 to 26.1 and on which each one has a lateral edge of one of the two adjacent ones via an outer fold line 21.2, 21.3 to 26.2, 26.3 Side walls 9 to 14 is connected.
Die Seitenwand 9 ist über eine geradlinige obere Faltlinie 27 mit einem Klappdeckel 28 verbunden, der eine Deckwand 29 mit ebenfalls sechseckiger Grundfläche aufweist. Neben dem seitlichen Rand, der über die obere Faltlinie 27 mit der Seitenwand 9 verbunden ist, weist die Deckwand 29 zwei konkave seitliche Ränder 30, 31 auf, die sich jeweils bis zu einer Ecke der Grundfläche erstrecken. Daran angrenzend weist die Deckwand 29 auf beiden Seiten jeweils zwei geradlinige seitliche Ränder auf, die sich bis zu der nächsten Ecke erstrecken. An diese seitlichen Ränder ist jeweils über eine seitliche Faltlinie 32, 33 eine Einstecklasche 34, 35 angelenkt. Die beiden äußeren Ecken jeder Einstecklasche 34, 35 weisen Rundungen auf. The side wall 9 is connected via a straight upper fold line 27 to a hinged lid 28 which has a top wall 29 also with a hexagonal base. In addition to the lateral edge, which is connected to the side wall 9 via the upper fold line 27, the top wall 29 has two concave lateral edges 30, 31, each of which extends to a corner of the base area. Adjacent to this, the top wall 29 has two straight lateral edges on both sides, which extend to the next corner. A tuck-in flap 34, 35 is articulated on each of these lateral edges via a lateral fold line 32, 33. The two outer corners of each tuck-in flap 34, 35 have curves.
Gegenüber dem seitlichen Rand, mit dem die Deckwand 29 über die obere Faltlinie 27 an die Seitenwand 9 angelenkt ist, weist die Deckwand 29 einen konkav gekrümmten seitlichen Rand 36 auf, der sich zwischen den beiden geradlinigen seitlichen Rändern mit den Einstecklaschen 34, 35 erstreckt. Opposite the lateral edge with which the top wall 29 is hinged to the side wall 9 via the upper fold line 27, the top wall 29 has a concavely curved lateral edge 36 which extends between the two straight lateral edges with the insertion flaps 34, 35.
Beidseitig neben der Seitenwand 9, die über die obere Faltlinie 27 mit dem Klappdeckel verbunden ist, weisen die beiden angrenzenden Seitenwände 10, 14 einen konvex gekrümmten oberen Rand 37, 38 auf, an dem jeweils über eine konvex gekrümmte obere Faltlinie 39, 40 eine Staublasche 41, 42 angelenkt ist.
Die Seitenwand 12, die gegenüber der Seitenwand 9 angeordnet ist, die über eine obere Faltlinie 27 mit dem Klappdeckel 28 verbunden ist, ist ebenfalls am oberen Rand 43 über eine konvex gekrümmte obere Faltlinie 44 mit einer Staublasche 45 verbunden. On both sides next to the side wall 9, which is connected to the hinged lid via the upper fold line 27, the two adjoining side walls 10, 14 have a convexly curved upper edge 37, 38, on which a dust flap is attached via a convexly curved upper fold line 39, 40 41, 42 is articulated. The side wall 12, which is arranged opposite the side wall 9, which is connected to the hinged lid 28 via an upper fold line 27, is also connected at the upper edge 43 via a convexly curved upper fold line 44 to a dust flap 45.
Die beiden äußeren Ecken jeder Staublasche 41, 42, 45 sind ebenfalls gerundet. The two outer corners of each dust flap 41, 42, 45 are also rounded.
Die Seitenwände 11, 13, die zwischen den Seitenwänden 10 und 12, 14 angeordnet sind, die über gekrümmte Faltlinien 39, 40, 44 mit Staublaschen 41, 42, 45 verbunden sind, weisen jeweils einen oberen Rand in Form einer geraden freien Kante 46, 47 auf. The side walls 11, 13, which are arranged between the side walls 10 and 12, 14, which are connected to dust flaps 41, 42, 45 via curved fold lines 39, 40, 44, each have an upper edge in the form of a straight free edge 46, 47 on.
Gemäß Fig. 2 ist die Faltschachtel 48 aufgerichtet, indem die Dreieckslaschen 15.1, 15.2 bis 20.1, 20.2 jeder Eckverbindung 15 bis 20 um die mittleren Faltlinien 21.1 bis 26.1 gegeneinander und gegen die Außenseite einer Seitenwand 9, 11, 13 geklappt und geklebt sind, deren oberer Rand geradlinig ausgebildet ist. Hierdurch wird ein becher- oder schalenförmiges Unterteil 49 gebildet. Die oberen Ränder der Seitenwände 9 bis 14 umgrenzen eine Öffnung 50 zum Befüllen und Entleeren des Unterteils der Faltschachtel 48. In diesem Zustand kann eine Vielzahl identisch ausgebildeter Faltschachteln 48 ineinandergenestet werden. According to Fig. 2, the folding box 48 is erected by folding the triangular flaps 15.1, 15.2 to 20.1, 20.2 of each corner connection 15 to 20 around the middle fold lines 21.1 to 26.1 against each other and against the outside of a side wall 9, 11, 13 and gluing them upper edge is straight. As a result, a cup or bowl-shaped lower part 49 is formed. The upper edges of the side walls 9 to 14 delimit an opening 50 for filling and emptying the lower part of the folding box 48. In this state, a large number of identically designed folding boxes 48 can be nested in one another.
Für das Befüllen kann eine einzelne Faltschachtel 48 aus dem Stapel entnommen werden. Nach dem Einfüllen von Salat oder einem anderen kleinstückigen Produkt werden die drei Staublaschen 41, 42, 45 über die Öffnung 50 zwischen den oberen Rändern der Seitenwände 9 bis 14 gefaltet, in eine etwa horizontale Ausrichtung. Hierdurch wird das eingefüllte Produkt zurückgehalten, auch wenn es bis zum oberen Rand des Unterteils 49 eingefüllt ist. Beim Umlegen der Staublaschen 41, 42,
45 werden die damit über obere Faltlinien 39, 40, 44 verbundenen Seitenwände 10, 12, 14 etwas nach innen gewölbt. A single folding box 48 can be removed from the stack for filling. After loading lettuce or other small-piece product, the three dust flaps 41, 42, 45 are folded over the opening 50 between the upper edges of the side walls 9-14, in an approximately horizontal orientation. As a result, the filled product is held back, even if it is filled up to the upper edge of the lower part 49. When turning over the dust flaps 41, 42, 45, the side walls 10, 12, 14 connected thereto via upper fold lines 39, 40, 44 are curved somewhat inwards.
Danach wird die Faltschachtel 48 durch Zuklappen des Klappdeckels 28 geschlossen. Hierbei wird gemäß Fig. 3 und 4 die Deckwand 29 seitlich an den gekrümmten oberen Rändern 37, 38 der Seitenwände 10, 14 geführt, die beidseitig der Seitenwand 9 angeordnet sind, an die der Klappdeckel 28 angelenkt ist. Hierdurch werden die Einstecklaschen 34, 35 auf die Spalte zwischen den Staublaschen 41, 45 und 42, 45 und die dazwischen angeordneten Seitenwänden 11, 13 ausgerichtet und können leicht in diese eingeführt werden. The folding box 48 is then closed by closing the hinged lid 28 . Here, according to FIGS. 3 and 4, the top wall 29 is guided laterally on the curved upper edges 37, 38 of the side walls 10, 14, which are arranged on both sides of the side wall 9 to which the hinged lid 28 is articulated. As a result, the insertion flaps 34, 35 are aligned with the gaps between the dust flaps 41, 45 and 42, 45 and the side walls 11, 13 arranged between them and can be easily inserted into them.
Gemäß den Fig. 5 bis 8 ist der Klappdeckel 28 der geschlossenen Faltschachtel 48 im Mittelbereich etwas nach oben ausgewölbt, sodass dort mehr Produkt untergebracht werden kann. According to FIGS. 5 to 8, the hinged lid 28 of the closed folding box 48 is slightly bulged upwards in the middle area, so that more product can be accommodated there.
An den übrigen Rändern wird die Deckwand 29 unten von den Staublaschen 41, 42, 45 abgedeckt. Die konkav gekrümmten seitlichen Ränder 30, 31, 36 der Deckwand 29 sind an die gekrümmten oberen Ränder der angrenzenden Seitenwände 10, 12, 14 angepasst. Hierdurch wird eine dicht und sicher schließende Klappdeckelschachtel erreicht.
The top wall 29 is covered at the bottom by the dust flaps 41, 42, 45 at the remaining edges. The concavely curved lateral edges 30,31,36 of the top wall 29 are adapted to the curved upper edges of the adjacent side walls 10,12,14. This achieves a tightly and securely closing hinged-lid box.
