Description

Die Erfindung bezieht sich auf eine Faltschachtel mit Boden und Seitenwänden, die aus einem Zuschnitt gefertigt ist, der mindestens acht Falzlinien aufweist, davon vier lange, zwischen dem Boden und jeweils einer Seitenwand angeordnete Falzlinien, die im Winkel von 90° aufeinanderstoßen und einander kreuzen, und je zwei kurze Falzlinien an zwei voneinander abgewandten Seitenteilen, wobei diese kurzen Falzlinien von Kreuzungspunkten, an denen die langen Falzlinien sich unter einem Winkel von 90° kreuzen, in einem von 90° abweichenden Winkel relativ zu den langen Falzlinien des Zuschnittes verlaufen. Eine solche Faltschachtel ist aus GB-A-2 084 961 bekannt.The invention relates to a folding box with base and side walls, which is made from a blank that has at least eight fold lines, four of which are long fold lines arranged between the base and one side wall, which meet and intersect at an angle of 90 °, and two short fold lines on two side parts facing away from each other, these short fold lines of crossing points, at which the long fold lines intersect at an angle of 90 °, run at an angle deviating from 90 ° relative to the long fold lines of the blank. Such a folding box is known from GB-A-2 084 961.

Bekannte Faltschachteln weisen einen Boden und vier Seitenteile auf. Der durch Stanzen hergestellte Zuschnitt weist entsprechende Laschen auf, die aufgerichtet und dann durch Verkleben, Einstecken oder ähnlichem miteinander verbunden werden. Die Schachteln werden entweder im Fertigungsbetrieb in Schachtelform hergerichtet oder aber dem Verbraucher in auseinandergenommenem, flach aufeinander gelegtem Zustand geliefert, der dann die Schachtel mit besonderen Füge- oder Heftsystemen zusammenbaut. Bei bekannten Schachteln fallen schon beim Stanzen der erforderlichen Zuschnitte in oft sehr erheblichem Umfang Verschnitte an. Außerdem erfordert das Lagern von fertigen oder halbfertigen Faltschachteln einen erheblichen Platzbedarf. Schließlich ist es auch für den Verbraucher oft mühsam und mit relativ hohen Kosten verbunden, wenn die Faltschachteln erst beim Verbraucher fertiggestellt werden.Known folding boxes have a bottom and four side parts. The blank produced by punching has corresponding tabs which are erected and then connected to one another by adhesive bonding, insertion or the like. The boxes are either prepared in the form of a box in the manufacturing plant or else the consumer in a disassembled, flat state supplied, which then assembles the box with special joining or tacking systems. In known boxes, cuts are often made to a considerable extent when the required blanks are punched. In addition, the storage of finished or semi-finished folding boxes requires a considerable amount of space. After all, it is often tedious for the consumer and associated with relatively high costs if the folding boxes are only completed at the consumer.

Auch sind Faltschachteln bekannt, die keine Heft- und Klebestellen aufweisen, jedoch sind sie mit so komplizierten Falzmustern versehen, daß sie beim Hersteller einen erhöhten Werkzeugaufwand verursachen und der Benutzer bei der Montage nicht unerhebliche Probleme zu bewältigen hat.Folding boxes are also known which have no stitching and gluing points, but they are provided with folding patterns which are so complicated that they cause an increased tool expenditure for the manufacturer and the user has to cope with not inconsiderable problems during assembly.

Der Erfindung liegt die Aufgabe zugrunde, eine Faltschachtel zu schaffen, die in bereits vorgefertigtem Zustand schnell aufzurichten und ebenso schnell wieder zusammenzulegen ist.The invention has for its object to provide a folding box that can be erected quickly in the prefabricated state and can be folded up again just as quickly.

Diese Aufgabe wird dadurch gelöst, daß sich die Falzlinien jeweils ganz bis zu den Rändern des Zuschnittes erstrecken und Verbindungsflächen abteilen, die jeweils von einer langen und einer kurzen Falzlinie sowie vom Rand des Zuschnitts begrenzt sind, und nach Aufrichten der Faltschachtel fest mit benachbarten Abschnitten anderer Seitenteile verbunden sind.This object is achieved in that the fold lines each extend all the way to the edges of the blank and divide connecting surfaces, each of which is delimited by a long and a short fold line and by the edge of the blank, and after the folding box has been erected are firmly connected to adjacent sections of other side parts.

Die Erfindung läßt sich mit einem Zuschnitt verwirklichen, der aus Karton, beschichtetem Karton, Kunststoff oder dergleichen besteht. Der Zuschnitt weist nur verhältnismäßig wenig Falzlinien auf und ist daher einfach herzustellen. Die Befestigung der Verbindungsflächen mit benachbarten Flächen kann durch Kleben, Klammern, Heften oder dergleichen erfolgen. Ein Vorteil der Erfindung liegt darin, daß das Aufrichten der Falzschachtel unkompliziert und schnell vor sich geht. Die erfindungsgemäßen Faltschachteln können zur Aufnahme von Nahrungsmitteln, Obst, Gemüse, Süßigkeiten, Nüssen oder dergleichen, aber auch zur Aufnahme von Büroutensilien wie Gummiringen, Büroklammern oder dergleichen dienen. Ihre Länge, Breite und Höhe ist in weiten Grenzen wählbar.The invention can be realized with a blank which consists of cardboard, coated cardboard, plastic or the like. The cut has only relatively few fold lines and is therefore easy to produce. The The connection surfaces can be attached to adjacent surfaces by gluing, stapling, stapling or the like. An advantage of the invention is that the folding box can be erected simply and quickly. The folding boxes according to the invention can be used to hold food, fruit, vegetables, sweets, nuts or the like, but also to hold office utensils such as rubber rings, paper clips or the like. Their length, width and height can be selected within wide limits.

Bei Ausführungsformen der Erfindung weist der Zuschnitt eine rechteckige, beispielsweise quadratische Form auf, so daß das Ausstanzen des Zuschnittes ohne Verschnitt erfolgen kann. Bei anderen Ausführungsformen der Erfindung weisen jedoch mindestens zwei voneinander abgewandte Ränder des Zuschnittes einen flachen Kreisbogenabschnitt auf. Dadurch lassen sich Faltschachteln herstellen, deren oberer Rand der aufgerichteten Seitenteile bogenförmig verläuft. Anstelle eines Kreisbogenabschnittes kann jedoch auch eine Wellenform oder eine Zickzackform oder dergleichen gewählt sein, die dann den oberen Rand eines Seitenteils der fertigen Schachtel bestimmt.In embodiments of the invention, the blank has a rectangular, for example square, shape, so that the blank can be punched out without waste. In other embodiments of the invention, however, at least two edges of the blank facing away from one another have a flat circular arc section. This makes it possible to produce folding boxes, the upper edge of which is curved in the erected side parts. Instead of a circular arc section, however, a wave shape or a zigzag shape or the like can also be selected, which then determines the upper edge of a side part of the finished box.

Bei Ausführungsformen der Erfindung können sich die Endpunkte der am Rande des Zuschnittes endenden kurzen Falzlinien eines Seitenteiles an einem Randpunkt treffen, so daß die von diesen Falzlinien abgeteilten Verbindungsflächen dreieckig sind. Die Endpunkte dieser kurzen Falzlinie am Rand des Zuschnittes können jedoch auch einen Abstand voneinander aufweisen, so daß sich eine Vielzahl von Schachtelformen ergibt.In embodiments of the invention, the end points of the short fold lines of a side part, which end at the edge of the blank, can meet at an edge point, so that the connecting surfaces divided by these fold lines are triangular. However, the end points of this short fold line at the edge of the blank can also be at a distance from one another, so that there is a multitude of box shapes.

Bei einer Ausführungsform der Erfindung sind in vorgefertigtem Zustand zwei voneinander abgewandte, keine kurzen Falzlinien aufweisende Seitenteile nach innen umgeklappt und liegen auf einem Bodenteil der Schachtel auf, wobei die Verbindungsflächen an den benachbarten Abschnitten befestigt sind. Die Faltschachtel befindet sich dann in einem flachen Zustand und kann in diesem Zustand gelagert werden. Dadurch reduziert sich die Gesamthöhe der zu lagernden vorgefertigten Faltschachtel auf etwa die doppelte Materialstärke des für die Herstellung verwendeten Materials. Von diesem vorgefertigten Zustand kann die Faltschachtel durch einfaches Verschwenken der umgeklappten Seitenteile aufgerichtet werden. Andererseits aber kann die erfindungsgemäße Faltschachtel durch Zurückschwenken von einander gegenüberliegenden Seitenteilen um die langen Falze in die Ebene des Bodenteils wieder in einen flachen Zustand gebracht werden.In one embodiment of the invention, in the prefabricated state, two side parts which face away from one another and have no short fold lines are folded inwards and lie on a base part of the box, the connecting surfaces being fastened to the adjacent sections. The folding box is then in a flat state and can be stored in this state. This reduces the total height of the prefabricated folding box to be stored to about twice the material thickness of the material used for the production. From this prefabricated state, the folding box can be erected by simply swiveling the folded side parts. On the other hand, the folding box according to the invention can be brought back into a flat state by pivoting back opposite side parts around the long folds into the plane of the bottom part.

Bei Ausführungsformen der Erfindung ist der Zuschnitt zur Bildung der Seitenteile durch zumindest zwei lange Falze in drei gleiche Teile eingeteilt, so daß die Höhe der Seitenwände der fertigen Schachtel der Breite des Bodenteiles entspricht.In embodiments of the invention, the blank for forming the side parts is divided into three equal parts by at least two long folds, so that the height of the side walls of the finished box corresponds to the width of the base part.

Bei Ausführungsformen der Erfindung weist der Zuschnitt noch einen durch die Mitte des Bodenteiles verlaufenden zusätzlichen Mittelfalz auf. Dadurch kann in vorgefertigtem Zustand die Schachtel noch kleiner zusammengefaltet werden.In embodiments of the invention, the blank also has an additional central fold running through the center of the base part. As a result, the box can be folded even smaller in the prefabricated state.

Weitere Merkmale der Erfindung ergeben sich aus der folgenden Beschreibung von Ausführungsformen der Erfindung in Verbindung mit den Ansprüchen und der Zeichnung.Further features of the invention result from the following description of embodiments of the invention in connection with the claims and the drawing.

Die einzelnen Merkmale können je für sich oder zu mehreren bei Ausführungsformen der Erfindung verwirklicht sein. In der Zeichnung sind Ausführungsformen der Erfindung dargestellt.The individual features can be implemented individually or in groups in embodiments of the invention.

Bei der in den Figuren 1 bis 4 dargestellten Ausführungsformen ist der gestanzte Zuschnitt beliebig groß, rechteckig und quadratisch. Er weist lange Falzlinien A, B, C, D, die sich rechtwinklig kreuzen, sowie kurze Falzlinien 13, 14, 15, 16 auf, die von Kreuzungspunkten 37 der langen Falzlinien A, B, C, D in einem von 90° abweichenden Winkel, z. B. 45°, zu dem benachbarten Rand 38 verlaufen und sich in einem Randpunkt 39 treffen, wo sie bei der dargestellten Ausführungsform einen Winkel von 90° einschließen. Sie teilen von den Seitenteilen 1 und 2 dreieckförmige Verbindungsflächen 17, 18, 19, 20 ab.In the embodiments shown in FIGS. 1 to 4, the punched blank is of any size, rectangular and square. It has long fold lines A, B, C, D, which cross at right angles, and short fold lines 13, 14, 15, 16, that of crossing points 37 of the long fold lines A, B, C, D at an angle other than 90 ° , e.g. B. 45 °, to the adjacent edge 38 and meet at an edge point 39, where they enclose an angle of 90 ° in the illustrated embodiment. They divide from the side parts 1 and 2 of triangular connecting surfaces 17, 18, 19, 20.

Nach dem Falzen des Zuschnittes wird an den Verbindungsflächen 17 bis 20 oder an deren Kanten Klebstoff oder dergleichen aufgebracht und die Seitenteile 3 und 4 werden entlang der Falze A und B soweit nach innen umgeklappt, daß sie flach auf einem Bodenteil 5 aufliegen (Fig. 2). Die dreieckigen Verbindungsflächen 17 bis 20 liegen dabei auf einem dreieckigen Teil der benachbarten Flächen 21, 22, 23 und 24 der Seitenteile 3 und 4 auf und sind dort dauerhaft befestigt. Durch beidseitiges Verschwenken der der beiden Seitenteile 3 und 4 an den Außenkanten 9 und 10 um die Falzlinien A und B verschwenken sich die Abschnitte 21 bis 24 der Seitenteile um die äußeren Bereiche der Falzlinien C und D und die sich bildenden Ecken 11 und 12 der Seitenteile 1 und 2 klappen nun die Falzlinien 13 und 14 nach hinten und unten (Fig. 3). Dadurch öffnet sich die Faltschachtel, der Bodenteil 5 wird freigegeben und die Seitenteile 1, 2, 3 und 4 richten sich rechtwinklig zum Bodenteil 5 auf (Fig. 4). Die Abschnite 21 bis 24 bilden dann zusammen mit den nun ebenfalls dreieckigen seitenteilen 1 und 2 die kurzen Seitenwände der fertigen Faltschachtel.After the blank has been folded, adhesive or the like is applied to the connecting surfaces 17 to 20 or at the edges thereof and the side parts 3 and 4 are folded inwards along the folds A and B until they lie flat on a base part 5 (FIG. 2 ). The triangular connecting surfaces 17 to 20 lie on a triangular part of the adjacent surfaces 21, 22, 23 and 24 of the side parts 3 and 4 and are permanently attached there. By pivoting the two side parts 3 and 4 on both sides of the outer edges 9 and 10 about the fold lines A and B, the sections 21 to 24 of the side parts pivot about the outer regions of the fold lines C and D and the corners 11 and 12 of the side parts that form 1 and 2 fold the fold lines 13 and 14 backwards and downwards (Fig. 3). This opens the folding box, the bottom part 5 is released and the side parts 1, 2, 3 and 4 are at right angles to the bottom part 5 (Fig. 4). Sections 21 to 24 then together with the now also triangular side parts 1 and 2 form the short side walls of the finished folding box.

Die Befestigung der Verbindungsflächen 17 bis 20 mit den benachbarten Flächen 21 bis 24 kann durch Kleben, Klammern, Heften oder dergleichen erfolgen. Die Größe des Bodenteils 5 kann bei einzelnen Ausführungsformen der Erfindung in seiner Länge und Breite variieren und damit ändert sich bei gleichem Umriß der Zuschnitte auch die Höhe der Seitenteile. Bei der in den Fig. 1 bis 4 dargestellten Ausführungsform ist das Bodenteil 5 doppelt so breit wie die Seitenteile 3 und 4, die die gleiche Breite aufweisen.The connection surfaces 17 to 20 can be attached to the adjacent surfaces 21 to 24 by gluing, stapling, stapling or the like. The size of the base part 5 can vary in length and width in individual embodiments of the invention and thus the height of the side parts changes with the same outline of the blanks. In the embodiment shown in FIGS. 1 to 4, the bottom part 5 is twice as wide as the side parts 3 and 4, which have the same width.

Eine fertige Faltschachtel kann wieder in den flachen Zustand versetzt werden, wenn die Seitenteile 3 und 4 nach unten auf die Bodenfläche 5 oder die Seitenteile 1 und 2 nach außen in die Ebene der Bodenfläche 5 gedrückt werden. Mit M ist in den Zeichnungen die Mittellinie des Zuschnittes und der fertigen Schachtel bezeichnet.A finished folding box can be put back into the flat state if the side parts 3 and 4 are pressed down onto the bottom surface 5 or the side parts 1 and 2 outwards into the plane of the bottom surface 5. M in the drawings denotes the center line of the blank and the finished box.

Die Fig. 5 und 6 zeigen weitere Ausführungsformen eines Zuschnittes mit verschiedener Anordnung der Falzlinien. Diese Figuren zeigen die Variabilität der Breite, Länge und Höhe der Seitenteile 1 bis 4 und des Bodenteiles 5 und Fig. 5 und 7 andere Winkel zwischen den kurzen und den langen Falzlinien.5 and 6 show further embodiments of a blank with different arrangement of the fold lines. These figures show the variability of the width, length and height of the side parts 1 to 4 and the bottom part 5 and FIGS. 5 and 7 other angles between the short and the long fold lines.

Bei der in Fig. 7 dargestellten Ausführungsform der Erfindung sind die Falzlinien so angeordnet, daß die Seitenteile 3' und 4' die gleiche Breite wie das Bodenteil 5' aufweisen. Beim Zusammenklappen des Zuschnittes überlappen sich die Seitenteile 3' und 4', da ja das Bodenteil 5' so breit ist wie ein Seitenteil 4' oder 3' (Fig. 8). Bei einer Ausführungsform der Erfindung verlaufen die äußeren Ränder 31, 32 der Seitenteile 3' und 4 ' in einem flachen Kreisbogenabschnitt oder aber in einer anderen, von einer Geraden abweichenden Form, z. B. in Wellenform oder Dachform. Diese Form erhält dann der obere Rand der Seitenteile (Fig. 9).In the embodiment of the invention shown in FIG. 7 the fold lines are arranged so that the side parts 3 'and 4' have the same width as the bottom part 5 '. When the blank is folded together, the side parts 3 'and 4' overlap, since the bottom part 5 'is as wide as a side part 4' or 3 '(FIG. 8). In one embodiment of the invention, the outer edges 31, 32 of the side parts 3 'and 4' run in a flat circular arc section or in another shape deviating from a straight line, e.g. B. in wave form or roof shape. The upper edge of the side parts then receives this shape (FIG. 9).

Die an den Rändern des Zuschnittes liegenden Enden 35 der Kreisbögen befinden sich beispielsweise im Abstand einer halben Seitenteilbreite der Seitenteile 3' und 4' von den Ecken 11 und 12. Dieser Abstand bestimmt die Höhe der Seitenwände der fertigen Schachtel an der betreffenden Stelle. Bei dieser Ausführungform entsteht beim Stanzen der Zuschnitte durch die Ausbildung der Kreisbögen 30 und 31 ein geringer Verschnitt.The ends 35 of the arcs lying on the edges of the blank are, for example, at a distance of half a side part width of the side parts 3 'and 4' from the corners 11 and 12. This distance determines the height of the side walls of the finished box at the relevant point. In this embodiment, when the blanks are punched, the circular arcs 30 and 31 form a small amount of waste.

Das Aufrichten dieser Faltschachtel gemäß den Fig. 7 bis 10 erfolgt in der gleichen Weise wie bei der Ausführungsform nach den Figuren 1 bis 4. Man erhält eine Faltschachtel gemäß Fig. 9, bei der sich die Abschnitte 23', 24' und 2' bzw. 21', 22' und 1' teilweise überlappen, sodaß diese Wände der Schachtel versteift sind. Außerdem liegen die Abschnitte 23' bzw. 22' teilweise zwischen den Abschnitten 2' und 24' bzw. 1' und 21', sodaß die Abschnitte 22' und 23' auch durch Reibung festgehalten werden. Dies führt zu einer zusätzlichen Aussteifung. Auch diese Faltschachtel läßt sich schnell wieder in einen flachen Zustand versetzen, wenn die Seitenteile 1' und 2' in die Ebene des Bodenteiles 5' zurückgedrückt werden.This folding box according to FIGS. 7 to 10 is erected in the same way as in the embodiment according to FIGS. 1 to 4. A folding box according to FIG. 9 is obtained in which the sections 23 ', 24' and 2 'or 21 ', 22' and 1 'partially overlap so that these walls of the box are stiffened. In addition, sections 23 'and 22' are partially between sections 2 'and 24' and 1 'and 21', respectively, so that sections 22 'and 23' are also held in place by friction. This leads to additional stiffening. This folding box can also be quickly put back into a flat condition if the side parts 1 'and 2' are pushed back into the plane of the base part 5 '.

Bei einer Ausführungsform der Erfindung ist längs der Mitte M des Bodenteils 5 bzw. 5' noch eine mittlere Falzlinie 33 vorgesehen, durch die die Faltschachtel halbiert wird und diese beiden Hälften in vorgefertigtem Zustand deckungsgleich aufeinanderliegen (Fig. 10).In one embodiment of the invention, a middle fold line 33 is also provided along the center M of the base part 5 or 5 ', through which the folding box is halved and these two halves are congruent with one another in the prefabricated state (FIG. 10).

Der Faltschachtel kann ein zweites, nach dem gleichen Prinzip hergestelltes Behältnis als Deckel zugeordnet sein.The folding box can be assigned a second container, which is manufactured according to the same principle, as a lid.
