Abstract

The method for the producing of a two-part packing of cardboard or corrugated cardboard from a one-piece blank with stamped sections (22,23) on opposite sides for later separation between an upper (1) and a lower (2) part, entails the gluing of the one-piece blank to form a flat-lying semi-finished packing, the assembling of the glued semi-finished packing, the moving past of the assembled, unfilled semi-finished packing on a cutting machine for the separation of the upper part and lower part from one another, and the sliding together of the upper and lower parts. An independent claim is included for a semi-finished packing for the producing of a two-part packing from cardboard or corrugated cardboard.

Description

Die Erfindung betrifft ein Verfahren zum Herstellen einer zweiteiligen, aus Oberteil und Unterteil bestehenden Verpackung aus Karton oder Wellpappe aus einem einstückigen Zuschnitt, wobei der Zuschnitt an zwei sich im zusammengefalteten Zustand gegenüberliegenden Seiten mit einem die spätere Trennung zwischen Oberteil und Unterteil markierenden Stanzschnitt versehen ist. Die Erfindung betrifft ferner ein Halbfertigprodukt.The invention relates to a method for producing a two-part, consisting of upper part and lower part packaging of cardboard or corrugated cardboard from a one-piece blank, wherein the blank is provided on two opposite sides in the folded state with a subsequent separation between the upper and lower part marking punched section. The invention further relates to a semi-finished product.

Es ist heutzutage üblich vorverpackte Produkte, die in Einzelhandelsunternehmen in Regalen zum Verkauf angeboten werden, in Kartonverpackungen zu verpacken, die aus einem Oberteil und einem Unterteil bestehen. Hierbei kann das Oberteil in der Regel vom Unterteil entfernt werden, und die verpackten Produkte, welche sich noch auf dem Unterteil befinden, direkt mit diesem in das Regal geschoben werden. Das Unterteil dient folglich als Tablett bzw. Tray.It is common nowadays to pack prepackaged products, which are sold on retail shelves, into carton packs consisting of a top and a bottom. In this case, the upper part can usually be removed from the lower part, and the packaged products, which are still on the lower part, are pushed directly with this in the shelf. The lower part thus serves as a tray or tray.

Entsprechende bekannte Kartonverpackungen, welche gemäß bekannter Verfahren hergestellt werden, sind im Hinblick auf ihre Herstellung teuer, da häufig zwei einzelne Teile in verschiedenen Vorrichtungen gefertigt werden, und erst kurz vor der Verpackung zusammengefügt werden. Es gibt daher seit einiger Zeit Bemühungen, entsprechende Kartonverpackungen aus einem einstückigen Zuschnitt herzustellen.Corresponding known paperboard packages, which are produced according to known methods, are expensive in terms of their production, since often two individual parts are manufactured in different devices, and are assembled only shortly before packaging. For some time now, efforts have therefore been made to manufacture corresponding cardboard packaging from a one-piece blank.

Aus der EP 0667 295 A2 ist eine einteilige Kartonverpackung bekannt, wobei die das Unter- und Oberteil umfassende Kartonverpackung zunächst aufgerichtet wird und die beiden Teile voneinander getrennt werden, bevor die Kartonverpackung befüllt wird. Hierbei wird die Trennung zwischen Ober- und Unterteil bereits bei der Herstellung durch Schwächungslinien deutlich gemacht, welche während des Trennungsvorganges durch Ausübung eines gegen die Wände der Verpackung ausgeübten Druckes voneinander getrennt werden. Die beiden Teile werden anschließend ineinandergeführt.From the EP 0667 295 A2 is a one-piece carton known, wherein the bottom and top cover comprehensive carton is first erected and the two parts are separated from each other before the carton is filled. In this case, the separation between upper and lower part is already made clear during manufacture by weakening lines, which are separated during the separation process by exerting a force exerted against the walls of the packaging pressure. The two parts are then brought together.

Eine weitere faltbare Verpackung ist auch aus der DE 200 00 449 U1 bekannt:Another foldable packaging is also from the DE 200 00 449 U1 known:

Ein anderes Verfahren zur Herstellung einer Verkaufsverpackung, sowie die Verkaufsverpackung selbst, ist aus der EP 1029 785 bekannt. Die beschriebene, aus einem einteiligen Zuschnitt hergestellte Verkaufsverpackung wird hierbei aufgerichtet, mit den zu verpackenden Produkten befüllt und erst anschließend in zwei Teile, das heißt in ein Oberteil und ein Unterteil getrennt. Auch hierbei werden bereits bei der Herstellung des Zuschnittes an entsprechenden Positionen die spätere Trennung markierende Wandschwächungen, wie Schlitze oder eine Perforation, ausgebildet, die als Trennhilfe zurAnother method for producing a sales package, as well as the sales package itself, is from the EP 1029 785 known. The described, made of a one-piece blank sales packaging is here erected, filled with the products to be packaged and only then separated into two parts, that is in a top and a bottom. Here, too, during the production of the blank at corresponding positions, the wall weakenings marking the subsequent separation, such as slots or a perforation, are formed, which serve as a separating aid for the

Trennung der Verkaufsverpackung vorgesehen ist. Das Ober- und Unterteil wird durch Schneiden voneinander getrennt und anschließend werden beide Teile ineinandergeschoben.Separation of the sales packaging is provided. The upper and lower part are separated by cutting and then both parts are pushed together.

Insbesondere, da bei dem letzteren Verfahren eine Trennung der Verkaufsverpackung erst nach Befüllung erfolgt, stellen die Schwächungslinien eine Beeinträchtigung der Stabilität der Verkaufsverpackung dar, gleichzeitig sind diese jedoch notwendig, um ein leichtes und kosteneffektives Trennen des Oberteils und des Unterteils zu gewährleisten. Hierbei kann die Trennung des Unterteils von dem Oberteil nach der Befüllung zu einer Beschädigung des eingefüllten Inhalts führen, z.B. wenn die Schneideinrichtung zu tief eingreift. Dies ist insbesondere nachteilig, wenn die Verpackung für flüssige Produkte beabsichtigt ist, z.B. Getränkekartons etc..In particular, since in the latter method a separation of the sales packaging takes place only after filling, the lines of weakness represent an impairment of the stability of the sales packaging, but at the same time they are necessary to ensure an easy and cost-effective separation of the upper part and the lower part. In this case, the separation of the lower part from the upper part after the filling can lead to a damage of the filled contents, e.g. when the cutter engages too deeply. This is particularly disadvantageous if the packaging is intended for liquid products, e.g. Beverage cartons etc.

Die Aufgabe der vorliegenden Erfindung ist es, die Nachteile des Standes der Technik zu überwinden und ein Verfahren zur Herstellung einer Verpackung aus Karton oder Wellpappe aus einem einstückigen Zuschnitt bereitzustellen, das sich durch eine besonders einfache und kostengünstige Herstellung auszeichnet.The object of the present invention is to overcome the disadvantages of the prior art and to provide a method for producing a cardboard or corrugated cardboard packaging from a one-piece blank, which is characterized by a particularly simple and cost-effective production.

Diese Aufgabe wird durch ein Verfahren zur Herstellung einer zweiteiligen, aus Oberteil und Unterteil bestehenden Verpackung aus Karton oder Wellpappe aus einem einstückigen Zuschnitt, wobei der Kartonzuschnitt an zwei sich im zusammengefalteten Zustand gegenüberliegenden Seiten mit einem die spätere Trennung zwischen Oberteil und Unterteil markierenden Stanzschnitt versehen ist, gelöst, welches folgende Schritte umfasst:

  • Verkleben des einstückigen Zuschnittes, um eine flachliegende Halbfertigverpackung zu bilden,
  • Aufrichten der Halbfertigverpackung,
  • Einschieben einer Stabilisierungs- und Bewegungseinrichtung in die Halbfertigpackung,
  • Vorbeibewegen der aufgerichteten, nicht befüllten Halbfertigverpackung an einer Schneideinrichtung zur Trennung des Oberteils und des Unterteils voneinander, und Zusammenschieben des Oberteils und des Unterteils.
This object is achieved by a method for producing a two-part, consisting of top and bottom packaging of cardboard or corrugated cardboard from a one-piece blank, wherein the carton blank is provided at two opposite sides in the folded state with a subsequent separation between the upper and lower part marking punched section , solved, which comprises the following steps:
  • Bonding the one-piece blank to form a flat semi-finished package,
  • Erecting the semi-finished packaging,
  • Inserting a stabilization and movement device into the semi-finished package,
  • Passing the erect, unfilled semi-finished packaging on a cutting device for separating the upper part and the lower part from each other, and pushing together of the upper part and the lower part.

Das erfindungsgemäße Verfahren ist einfach und kostengünstig durchzuführen. Da die Verpackung in dem halbfertigen Zustand an der Schneideinrichtung vorbeigeführt wird, kann hier eine fest angeordnete Schneideinrichtung eingesetzt werden. Das Verfahren lässt sich hierbei gleichermaßen für Verpackungen einsetzen, bei welchen das Oberteil in das Unterteil eingeschoben wird, wie auch bei Verpackungen, bei welchen das Oberteil über das Unterteil geschoben wird. Nach dem Aufrichten der Halbfertigverpackung wird eine Stabilisierungs- und Bewegungseinrichtung in die Halbfertigverpackung eingeschoben werden. Hierbei bietet sich zum Beispiel ein Formatblock an, dessen Außenabmessungen etwas kleiner sind als die Innenmaße der Verpackung aus Karton oder Wellpappe. Da die Verpackung an der Schneideinrichtung vorbeigeführt wird, ist ein gleichmäßiger Schnitt gewährleistet, ohne dass aufwendige Markierungen für die Schneidlinie notwendig werden.The inventive method is simple and inexpensive to perform. Since the package is passed in the semi-finished state of the cutter, a fixed cutter can be used here. The method can be used equally for packaging in which the upper part is inserted into the lower part, as well as in packaging in which the upper part is pushed over the lower part. After erecting the semi-finished packaging, a stabilizing and moving device will be inserted into the semi-finished package. Here, for example, offers a format block whose outer dimensions are slightly smaller than the inner dimensions of the packaging made of cardboard or corrugated cardboard. Since the packaging is guided past the cutting device, a uniform cut is ensured without the need for complicated markings for the cutting line.

Vorteilhafterweise kann vorgesehen sein, dass nach dem rechtwinkligen Aufrichten der Halbfertigverpackung zunächst die Bodenabschnitte verschlossen werden. In diesem Fall weist die Verpackung eine höhere Bodenstabilität auf, was sich vorteilhaft auf den Trennungsvorgang auswirkt.Advantageously, it can be provided that after the right-angled erecting of the semi-finished packaging, the bottom sections are first closed. In this case, the packaging has a higher soil stability, which has an advantageous effect on the separation process.

Vorteilhafterweise kann die Halbfertigverpackung mittels der Stabilisierungs- und Bewegungseinrichtung an der Schneideinrichtung vorbeibewegt werden. Die eingeführte Einrichtung stellt sicher, dass die Halbfertigverpackung auch während der ausgeführten Bewegung formstabil bleibt. Durch die Kombination der Bewegung mit der Stabilisierung kann das Verfahren wie auch die notwendige Vorrichtung vereinfacht werden.Advantageously, the semi-finished packaging can be moved past the cutting device by means of the stabilization and movement device. The introduced device ensures that the semi-finished packaging remains dimensionally stable during the movement that is being performed. By combining the movement with the stabilization, the process as well as the necessary apparatus can be simplified.

Vorzugsweise kann als Schneideinrichtung ein Schneidmesser, insbesondere mit einem wellenförmigen Klingenschliff, eingesetzt werden. Eine entsprechende Schneideinrichtung hat sich in der Praxis als besonders geeignet erwiesen.Preferably, as a cutting device, a cutting blade, in particular with a wavy blade grinding, can be used. A corresponding cutting device has proven to be particularly suitable in practice.

Alternativ kann jede erdenkliche Schneideinrichtung, die rotierend tief in die Verpackung eindringen kann, verwendet werden, da ja wie beschrieben die ungefüllte Verpackung geschnitten wird.Alternatively, any conceivable cutting device that can penetrate rotatingly deep into the packaging can be used, since the unfilled packaging is cut as described.

Gemäß einer weiteren bevorzugten Ausführungsform kann das abgetrennte Oberteil nach der Trennung durch die Stabilisierungs- und Bewegungseinrichtung so in das Unterteil eingeschoben werden, dass die Seitenwände des Oberteils auf der Bodeninnenfläche des Unterteils aufstehen.According to a further preferred embodiment, the severed upper part can be pushed into the lower part after the separation by the stabilizing and moving device so that the side walls of the upper part stand up on the bottom inner surface of the lower part.

Gemäß einer anderen bevorzugten Ausführungsform kann das abgetrennte Oberteil nach der Trennung durch die Stabilisierungs- und Bewegungseinrichtung so über das Unterteil geschoben werden, dass die Seitenwände des Unterteils an der Deckelinnenfläche des Oberteils angrenzen.According to another preferred embodiment, the severed upper part can be pushed over the lower part after separation by the stabilizing and moving device so that the side walls of the lower part adjoin the inner lid surface of the upper part.

Vorteilhafterweise kann während des Zusammenschiebens des Unterteils und des Oberteils von außen auf die Wände des Unterteils oder des Oberteils ein nach innen gerichteter Druck ausgeübt werden. Hierdurch wird der Außenumfang des einzuschiebenden Teils verringert und der Vorgang des Einschiebens erleichtert. Nach Rücknahme des Drucks liegen die Außenflächen der Wände des eingeschobenen Teils dann an den Innenflächen des außen angeordneten Teils an.Advantageously, during the pushing together of the lower part and the upper part from the outside on the walls of the lower part or of the upper part, an inwardly directed pressure can be exerted. As a result, the outer circumference of the part to be inserted is reduced and the process of insertion is facilitated. After withdrawal of the pressure, the outer surfaces of the walls of the inserted part then bear on the inner surfaces of the externally arranged part.

Gemäß einer anderen Ausführungsform kann vor dem Zusammenschieben des Oberteils und des Unterteils ein Verbindungsmedium auf wenigstens eine vorbestimmte Position an der seitlichen Außenoberfläche des Oberteils oder des Unterteils aufgebracht werden. Das zusätzliche Verbindungsmedium zwischen Oberteil und Unterteil erhöht die Stabilität der Verpackung aus Karton oder Wellpappe. Gleichzeitig wird im befüllten Zustand eine Trennung von Oberteil und Unterteil ausgeschlossen, z.B. bei der Handhabung während eines Konfektionierungsvorganges.According to another embodiment, prior to the pushing together of the upper part and the lower part, a connecting medium can be applied to at least one predetermined position on the lateral outer surface of the upper part or of the lower part. The additional connection medium between the upper part and the lower part increases the stability of the cardboard or corrugated cardboard packaging. At the same time a separation of the upper part and lower part is excluded in the filled state, e.g. during handling during a packaging process.

Vorteilhafterweise können nach dem Zusammenschieben des Oberteils und des Unterteils die Seitenwände im Bereich des aufgebrachten Verbindungsmediums gegeneinander gedrückt werden. Hierdurch wird die Verbindungsstelle zusätzlich fixiert und die Klebewirkung erhöht.Advantageously, after pushing together of the upper part and the lower part, the side walls in the region of the applied connection medium can be pressed against each other. As a result, the joint is additionally fixed and increases the adhesive effect.

Gemäß einer anderen bevorzugten Ausführungsform können bei dem einstückigen Zuschnitt die im zusammengefalteten Zustand zwischen den mit Stanzschnitt versehenen Seiten liegenden, die beiden anderen Wände bildenden Bereiche schwächungslinienfrei ausgebildet sein. Ein entsprechender Zuschnitt für eine zweiteilige Verpackung aus Karton oder Wellpappe ist kostengünstig herzustellen. Da es sich um einen einstückigen Zuschnitt handelt, ist lediglich eine einzige Vorrichtung zur Herstellung notwendig. Durch die schwächungslinienfreie Herstellung der beiden Seitenteile wird ein Zuschnitt mit hoher Stabilität erzielt, so dass bei der Lagerung, wie auch bei der Weiterverarbeitung derselben, keine besonderen Maßnahmen zur möglichst schonenden Behandlung notwendig sind.According to another preferred embodiment, in the one-piece blank, the areas lying in the folded state between the sides provided with punched cut and forming the two other walls can be formed without weakening lines. A corresponding blank for a two-part packaging made of cardboard or corrugated cardboard is inexpensive to manufacture. Since it is a one-piece blank, only a single device for production is necessary. Due to the weakening line-free production of the two side parts a blank with high stability is achieved, so that during storage, as well as in the further processing of the same, no special measures for the gentlest possible treatment are necessary.

Vorteilhafterweise kann der das Oberteil bildende Bereich des einstückigen Zuschnitts einen durch eine Schamierfaltlinie von den Wänden abgetrennten Deckelbereich und der das Unterteil bildende Bereich des einstückigen Zuschnitts einen durch eine Schamierfaltlinie von den Wänden abgetrennten Bodenbereich aufweisen, wobei der Stanzschnitt in einem vorbestimmten Abstand vom Boden parallel zu diesem angeordnet ist. Hierbei gibt die Entfernung des Stanzschnittes vom Boden die Höhe des späteren Tabletts bzw. Trays an.Advantageously, the portion of the one-piece blank forming the top can have a lid portion separated from the walls by a hinge fold and the bottom portion of the one-piece blank having a bottom portion separated from the walls by a hinge fold line, the punch cut being parallel to a predetermined distance from the bottom this is arranged. Here, the distance of the punched cut from the ground indicates the height of the later tray or tray.

Ferner kann sich der Stanzschnitt des einstückigen Zuschnitts über einen vorbestimmten Bereich zumindestens einseitig in die schwächungslinienfreien Bereiche erstrecken. Hierdurch wird eine Trennungshilfe bereitgestellt, da sich das Schneidwerkzeug an den Stanzschnitten hinsichtlich der Trennung orientieren kann, bzw. vor dem tatsächlichen Schneidvorgang bereits in den Stanzschnitt eingreifen kann.Furthermore, the punched cut of the one-piece blank can extend over a predetermined region at least on one side into the lines of weakness-free region. As a result, a separation aid is provided, since the cutting tool can orientate itself at the punched cuts with respect to the separation, or can already intervene in the punching cut before the actual cutting operation.

Gemäß einer anderen bevorzugten Ausführungsform kann wenigstens an einer zwischen den einzelnen Wänden des einstückigen Zuschnitts angeordneten Schamierfaltlinie ein Schlitz und/oder eine Aussparung angeordnet sind, welche sich von der Stanzlinie aus einen vorbestimmten Abstand in das Oberteil oder das Unterteil hinein erstreckt. Diese Ausführungsform gewährleistet eine Verschiebung der Wände des Oberteils oder des Unterteils zueinander, wenn das Oberteil im zusammengesetzten Zustand in das Unterteil eingeschoben wird, oder das Oberteil auf das Unterteil aufgesetzt wird.According to another preferred embodiment, a slot and / or a recess are arranged at least at one arranged between the individual walls of the one-piece blank Schamierfaltlinie which extends from the punching line from a predetermined distance in the upper part or the lower part. This embodiment ensures a displacement of the walls of the upper part or the lower part to each other when the upper part is inserted in the assembled state in the lower part, or the upper part is placed on the lower part.

Vorteilhafterweise kann die Länge der Schlitze und/oder Aussparungen in etwa der Höhe des Unterteils im zusammengefalteten Zustand, das heißt dem Abstand zwischen Boden und Stanzschnitt, entsprechen. Hierdurch kann insbesondere, wenn das Oberteil in das Unterteil eingeschoben wird, sichergestellt werden, dass das Oberteil möglichst vollständig in das Unterteil eingeführt wird, so dass das Oberteil den Boden des Unterteils berührt und das die Ecken des Unterteils auf den Ecken der Aussparungen aufsitzen und das die Ecken der Aussparungen auf den Ecken des Unterteils aufsitzen. Dies erhöht insbesondere die Stabilität der Verpackung aus Karton oder Wellpappe im befüllten Zustand unter vertikaler Belastung.Advantageously, the length of the slots and / or recesses in approximately the height of the lower part in the folded state, that is the distance between the bottom and punched section correspond. As a result, in particular, when the upper part is inserted into the lower part, it is ensured that the upper part is inserted as completely as possible into the lower part, so that the upper part touches the bottom of the lower part and the corners of the lower part sit on the corners of the recesses and the sit the corners of the recesses on the corners of the base. This increases in particular the stability of the packaging made of cardboard or corrugated cardboard in the filled state under vertical load.

Gemäß einer anderen bevorzugten Ausführungsform kann die Ausnehmung zumindestens an einer der an die Scharnierfaltlinie angrenzenden Wände parallel zu der Scharnierfaltlinie verlaufen und in ihrem Endbereich sich von der Scharnierfaltlinie auf den Stanzschnitt zu erstrecken. Durch die breiter ausgebildete Ausnehmung wird die Beweglichkeit der einzelnen Wände des Oberteils zueinander erhöht. Gleichzeitig bildet der Abschluss der Ausnehmung eine Ecke, die dann auf einer zugeordneten Ecke des Unterteils aufsitzen kann. Hierdurch kann einfach durch optische Kontrolle festgestellt werden, ob das Oberteil vollständig in das Unterteil eingeführt wurde. Gleichermaßen kann auch überprüft werden ob das Oberteil vollständig auf das Unterteil aufgesetzt wurde.According to another preferred embodiment, the recess may extend parallel to the hinge fold line at least on one of the walls adjacent to the hinge fold line and extend in its end region from the hinge fold line to the punch cut. Due to the wider recess is the Mobility of the individual walls of the shell increased to each other. At the same time the conclusion of the recess forms a corner, which can then sit on an associated corner of the base. As a result, it can be easily determined by visual inspection whether the upper part has been completely inserted into the lower part. Similarly, it can also be checked whether the upper part has been placed completely on the lower part.

Vorteilhafterweise können die im zusammengefalteten Zustand aufeinander stoßenden und miteinander verbundenen Längskanten der den Zuschnitt begrenzenden Wände mit einer an den Stanzschnitt, sich einen vorbestimmten Abstand in Richtung des Oberteils erstreckenden Aussparung versehen sein. Hierdurch wird sichergestellt, dass an allen vier Kanten entsprechende Aussparungen ausgebildet werden.Advantageously, the folded-together in the folded state and interconnected longitudinal edges of the blank defining walls may be provided with a recess extending to the punching cut, a predetermined distance in the direction of the upper part. This ensures that corresponding recesses are formed on all four edges.

Gemäß einer anderen bevorzugten Ausführungsform kann im Bereich der Vorderwand des einstückigen Zuschnitts eine Ausnehmung ausgebildet sein, welche sich von dem Stanzschnitt aus bis einen vorbestimmten Abstand unterhalb der das Oberteil von dem Deckelbereich begrenzenden Scharnierfaltlinie erstreckt. Eine entsprechende Ausnehmung gewährleistet, dass die eingepackten Produkte auch bei geschlossener Verpackung einfach erkennbar sind, so dass auf aufwendige Bedruckung der Verpackung oder andere Markierungen verzichtet werden kann.According to another preferred embodiment, a recess may be formed in the region of the front wall of the one-piece blank, which recess extends from the punched cut to a predetermined distance below the hinged fold line delimiting the upper part of the lid region. A corresponding recess ensures that the packaged products are easily recognizable even when the packaging is closed, so that expensive packaging of the packaging or other markings can be dispensed with.

Vorteilhafterweise kann die Ausnehmung in der Vorderwand im wesentlichen rechteckig ausgebildet sein. Eine rechteckige Ausnehmung stellt hierbei ein ausreichend großes Sichtfeld zur Verfügung, um ein Identifizieren der Ware zu ermöglichen.Advantageously, the recess in the front wall may be formed substantially rectangular. A rectangular recess here provides a sufficiently large field of view available to allow identification of the goods.

Hierbei kann die Ausnehmung in der Vorderwand im Bereich des Stanzschnittes einstückig mit den an den Scharnierfaltlinien ausgebildeten Ausnehmungen ausgebildet sein. Auf diese Weise wird eine einzige große Ausnehmung in der Vorderwand ausgebildet und dünne, möglicherweise instabile Bereiche vermieden.In this case, the recess in the front wall in the region of the punched cut can be formed integrally with the recesses formed on the hinge fold lines. In this way, a single large recess is formed in the front wall and thin, possibly unstable areas are avoided.

Ferner können die von dem Stanzschnitt abgewandten Ecken der Ausnehmung in der Vorderwand abgerundet ausgebildet sein.Furthermore, the corners of the recess remote from the stamped cut can be rounded in the front wall.

Vorteilhafterweise kann der Abstand zwischen der das Oberteil begrenzenden Schamierfaltlinie und der Ausnehmung in der Vorderwand größer sein, als die Höhe des Unterteils zwischen Scharnierfaltlinie und Stanzschnitt. Diese Ausführungsform gewährleistet eine ausreichende Stabilität der fertigen Verpackung aus Karton oder Wellpappe.Advantageously, the distance between the upper part limiting Schamierfaltlinie and the recess in the front wall may be greater than the height of the lower part between hinge fold line and punch cut. This embodiment ensures sufficient stability of the finished cardboard or corrugated cardboard packaging.

Gemäß einer bevorzugten Ausführungsform kann der Stanzschnitt in der Vorderwand des einstückigen Zuschnitts auf einer Linie mit dem Stanzschnitt in der Rückwand liegen. Hierbei werden das Oberteil und das Unterteil durch einen waagerechten Schnitt voneinander getrennt.According to a preferred embodiment, the punched cut in the front wall of the one-piece blank may lie in line with the punched cut in the rear wall. Here, the upper part and the lower part are separated by a horizontal section.

Gemäß einer anderen bevorzugten Ausführungsform kann der Stanzschnitt in der Vorderwand des einstückigen Zuschnitts oberhalb oder unterhalb des Stanzschnittes in der Rückwand liegen. Werden das Oberteil und das Unterteil bei dieser Ausführungsform voneinander getrennt, erfolgt dieses über einen schräg verlaufenden Schnitt, hierdurch erhält das abgetrennte Unterteil die Form einer Displayverpackung.According to another preferred embodiment, the punching cut in the front wall of the one-piece blank can be above or below the punched cut in the rear wall. If the upper part and the lower part are separated from each other in this embodiment, this takes place via an oblique cut, thereby the severed lower part is replaced by the shape of a display packaging.

Gemäß noch einer anderen Ausführungsform können in etwa mittig im Bereich der Seitenwände des einstückigen Zuschnitts im wesentlichen rechteckige Durchgriffsöffnungen angeordnet sein. Diese Durchgriffsöffnungen dienen insbesondere als Trennungshilfe, wenn die ineinandergeführten Teile der Verpackung aus Karton oder Wellpappe während des Auspackens der Ware wieder voneinander getrennt werden sollen. Die Durchgriffsöffnungen sind hierbei mittig, in dem das Oberteil bildenden Bereich angeordnet, vorzugsweise in etwa mit einem Abstand von der späteren Trennungslinie, der in etwa der Höhe des Unterteils entspricht, so dass die Durchgriffsöffnungen auch nach dem Ineinanderführen der beiden Teile von außen sichtbar sind. Da die Durchgriffsöffnungen im wesentlichen an dem Übergang zwischen Oberteil und Unterteil im zusammengesetzten Zustand liegt, kann eine ausreichende Kraft beim Entfernen ausgeübt werden, so dass hier eine Entfernung durch einen Handgriff möglich wird.According to yet another embodiment, substantially rectangular passage openings can be arranged approximately in the center of the side walls of the one-piece blank. These passage openings serve in particular as a separation aid when the parts of the cardboard or corrugated cardboard packaging which are guided one inside the other are to be separated from one another again during the unpacking of the goods. In this case, the passage openings are arranged centrally in the region forming the upper part, preferably approximately at a distance from the later dividing line, which corresponds approximately to the height of the lower part, so that the access openings are visible from the outside even after the two parts have been brought into one another. Since the through openings is located substantially at the transition between the upper part and lower part in the assembled state, a sufficient force can be exerted during removal, so that a removal by a handle is possible here.

Hierbei können sich ausgehend von der Durchgriffsöffnung in der Seitenwand Schwächungslinien nach unten bis zu dem das Unterteil bildenden Bereich erstrecken. Hierdurch ist es möglich, einen kleinen Bereich von dem Oberteil abzutrennen, z.B. wenn das Oberteil und das Unterteil miteinander verklebt werden.In this case, starting from the access opening in the side wall, weakening lines may extend down to the area forming the lower part. This makes it possible to separate a small area from the top, e.g. when the upper part and the lower part are glued together.

Vorteilhafterweise kann die Höhe des Oberteils der Verpackung aus Karton oder Wellpappe nach der Trennung in etwa der Höhe des zu verpackenden Erzeugnisses entsprechen. Hierdurch wird eine sichere Verpackung der Produkte erzielt, da diese vollkommen in der Verpackung aufgenommen werden.Advantageously, the height of the upper part of the cardboard or corrugated cardboard packaging after separation may correspond approximately to the height of the product to be packaged. As a result, a secure packaging of the products is achieved because they are completely absorbed in the package.

Im Folgenden wird die Erfindung anhand einer Ausführungsform näher erläutert. Es zeigt:

Der in Fig. 1 dargestellte Kartonagenzuschnitt umfasst ein Oberteil 1 und ein mit diesem verbundenes Unterteil 2, die zusammen den Behälterkorpusbereich bilden.1 comprises a top part 1 and a bottom part 2 connected thereto, which together form the container body region.

Der Behälterkorpusbereich besteht im wesentlichen aus einer rechteckigen Rückwand 3, einer ersten Seitenwand 4, einer Vorderwand 5 und einer zweiten Seitenwand 6. Diese vier Wände 3, 4, 5, 6 weisen jeweils eine Rechteckform auf und sind über parallel zueinander angeordnete Scharnierfaltlinien 7, 8, 9 und 10 miteinander verbunden.The container body region essentially consists of a rectangular rear wall 3, a first side wall 4, a front wall 5 and a second side wall 6 four walls 3, 4, 5, 6 each have a rectangular shape and are connected to each other via parallel arranged hinge fold lines 7, 8, 9 and 10.

Die Seitenwand 6 weist an einer ihrer Längsseite, d.h. der Scharniertaltlinie10, eine Klebelasche 11 auf, die zum Verbinden mit der Rückwand 3 dient. Diese Klebung wird von Seiten des Zuschnittherstellerbereichs vorgenommen, so dass die Wände 3, 4, 5, 6 als flacher Rechteckschlauch aufeinander liegen.The side wall 6 has on one of its longitudinal side, i. the hinged line 10, an adhesive tab 11, which serves to connect to the rear wall 3. This bond is made on the part of the blank manufacturer area, so that the walls 3, 4, 5, 6 lie on each other as a flat rectangular tube.

An die Wände 3, 4, 5, 6 schließen sich im Bereich des Oberteils 1 jeweils rechteckig ausgebildete Deckelabschnitte 14, 15, 16, 17 an. Die Deckelabschnitte 14, 15, 16, 17 sind über die Scharnierfaltelinie 13 von den Wänden 3, 4, 5, 6 getrennt. Hierbei weisen die Deckelabschnitte jeweils die gleiche Länge auf, und entsprechen in ihrer Breite dem jeweiligen Wandabschnitt, dem sie zugeordnet sind. Die Deckelabschnitte 14, 15, 16 und 17 sind jeweils durch Schnitte voneinander beabstandet und können getrennt voneinander auf- und zugeklappt werden.On the walls 3, 4, 5, 6 close in the region of the upper part 1 each rectangular shaped lid portions 14, 15, 16, 17 at. The lid sections 14, 15, 16, 17 are separated from the walls 3, 4, 5, 6 via the hinge fold line 13. In this case, the cover sections each have the same length, and correspond in width to the respective wall section to which they are associated. The cover sections 14, 15, 16 and 17 are each spaced apart by cuts and can be opened and closed separately from each other.

Gleichermaßen sind in Verlängerung der Wände 3, 4, 5, 6 im Bereich des Unterteils 1 rechteckige Bodenabschnitte 18, 19, 20, 21 ausgebildet, die jeweils über die Schamierfaltlinie 12 von der jeweiligen Wand abgegrenzt werden. Die Länge der Bodenabschnitte 18, 19, 20, 21 ist hierbei jeweils gleich ausgebildet und entspricht vorzugsweise der Länge der Deckelabschnitte. Die Breite entspricht der Breite der jeweiligen Wand.Similarly, in the extension of the walls 3, 4, 5, 6 in the region of the lower part 1 rectangular bottom portions 18, 19, 20, 21 are formed, which are each delimited on the Schamierfaltlinie 12 of the respective wall. The length of the bottom sections 18, 19, 20, 21 is in each case identical and preferably corresponds to the length of the lid sections. The width corresponds to the width of the respective wall.

Die Rückwand 3 und die Vorderwand 5 sind jeweils über ihre ganze Breite mit einem Stanzschnitt 22, 23 versehen, welcher jeweils die Trennung zwischen Oberteil 1 und Unterteil 1 markiert. Der Stanzschnitt 22 der Rückwand 3 erstreckt sich hierbei über die Scharnierfaltlinie 7 hinaus einen vorbestimmten Bereich in die Seitenwand 4 hinein.The rear wall 3 and the front wall 5 are each provided over their entire width with a punched cut 22, 23, which in each case marks the separation between upper part 1 and lower part 1. The punched cut 22 of the rear wall 3 in this case extends beyond the hinge fold line 7 beyond a predetermined area in the side wall 4 inside.

Ferner ist die Scharnierfaltlinie 7 im Bereich des Stanzschnittes 22 ausgehend von diesem mit einer Aussparung 24 versehen, welche sich ausgehend von dem Stanzschnitt 22 in Richtung des Oberteils 1 erstreckt. Im gefalteten Zustand wird hierdurch ein Bereich der von der Scharnierfaltelinie 7 gebildeten Kante ausgespart. Die Aussparung 24 ist hierbei solchermaßen ausgebildet, dass sich ihre Kante im Bereich der Rückwand 3 zunächst ausgehend von dem Stanzschnitt 22 nach oben auf die Scharnierfaltlinie 7 zu erstreckt und anschließend parallel zu der Schamierkante unter einem vorbestimmten Abstand zu dieser verläuft und schließlich in einem Bogen auf diese trifft. Anschließend verläuft die Kante der Aussparung entsprechend bis zu dem Stanzschnitt im Bereich der Seitenwand 4, so dass die Aussparung im wesentlichen glockenförmig ausgebildet ist. Das Ende der Aussparung 24 im Bereich der Seitenwand 4 entspricht hierbei auch dem Ende des Stanzschnittes 22.Furthermore, the hinge fold line 7 is provided in the region of the punched cut 22 starting from this with a recess 24 which extends from the punched cut 22 in the direction of the upper part 1. In the folded state, a region of the edge formed by the hinge fold line 7 is hereby cut out. The recess 24 is in this case designed in such a way that its edge in the region of the rear wall 3 initially extends from the punching cut 22 upwards to the hinge fold line 7 and then runs parallel to the hinge edge at a predetermined distance therefrom and finally in an arc this hits. Subsequently, the edge of the recess extends correspondingly up to the punched cut in the region of the side wall 4, so that the recess is substantially bell-shaped. The end of the recess 24 in the region of the side wall 4 in this case also corresponds to the end of the punched cut 22.

Die der Schamierfaltlinie 7 gegenüberliegende Längskante der Rückwand 3, das heißt die Seite, welche mit der Klebelasche 11 verklebt wird, ist ebenfalls ausgehend von dem Stanzschnitt 22 mit einer Aussparung 26 versehen, welche sich zunächst von dem Stanzschnitt 22 aus in den Bereich des Oberteils 1 senkrecht zu dem Stanzschnitt erstreckt und schließlich in einer Biegung auf die Längskante zu verläuft und senkrecht auf diese trifft.The longitudinal edge of the rear wall 3 lying opposite the hinge fold line 7, that is to say the side which is adhesively bonded to the adhesive flap 11, is likewise provided starting from the punched cut 22 with a recess 26 which initially projects from the punching cut 22 into the region of the upper part 1 extends perpendicular to the punching cut and finally extends in a bend on the longitudinal edge and perpendicular to this meets.

Gleichermaßen ist auch die Längskante 10 der Seitenwand 6, an welche sich die Klebelasche 11 anschließt, mit einer Aussparung 26a versehen, durch welche die Klebelasche 11 unterbrochen wird. Die Form der Aussparung 26a entspricht hierbei in etwa der Form der Aussparung.24 im Bereich der Rückwand 3.Likewise, the longitudinal edge 10 of the side wall 6, which is followed by the adhesive flap 11, provided with a recess 26 a, through which the adhesive flap 11 is interrupted. The shape of the recess 26a corresponds approximately to the shape of the recess in the region of the rear wall.

Auch der Stanzschnitt 23 der Vorderseite 5 erstreckt sich über die Scharnierfaltlinie 8 und 9 bis in die angrenzenden Seitenwände 4 und 6 hinaus. Die Enden des Stanzschnittes 23 im Bereich der angrenzenden Wände 4 und 6 sind hierbei entsprechend der Ausnehmung 24 ausgebildet, d.h. auch hier erstreckt sich jeweils eine zumindestens halbseitig bogenförmig ausgebildete Aussparung 28, 29. Im Gegensatz zu der Rückwand ist die Vorderwand 5 jedoch nicht mit identisch ausgebildeten, sich zu einer Glockenform zusammenschließenden Aussparungen versehen, vielmehr weist die Vorderwand eine weitere Ausnehmung 27 auf, in welche die Aussparungen 28, 29 münden, so dass eine große Durchtrittsöffnung entsteht.The punching cut 23 of the front side 5 also extends beyond the hinge fold line 8 and 9 into the adjacent side walls 4 and 6. The ends of the punching cut 23 in the region of the adjacent walls 4 and 6 are in this case formed corresponding to the recess 24, i. In contrast to the rear wall, however, the front wall 5 is not provided with identically formed recesses which join together to form a bell shape; rather, the front wall has a further recess 27 in which the recesses 28, 29 open, so that a large passage opening is formed.

Die Ausnehmung 27 beginnt hierbei an dem Stanzschnitt 23 und erstreckt sich ein vorbestimmtes Maß bis unterhalb der Scharnierfalte 13. Der Abstand zwischen Scharnierfalte 12 und der Ausnehmung 27 ist vorzugsweise größer als der Bereich zwischen der Schamierfaltlinie 12 und dem Stanzschnitt 23. Die Ausnehmung 27 in der Vorderwand 5 ist im wesentlichen rechteckig ausgebildet, und erstreckt sich parallel zu den Schamierfaltelinien 8 und 9 sowie parallel zu der Scharnierfalte 13. Hierbei ist der Übergang zwischen den parallel zu den Schamierfalten 8 und 9 verlaufenden Schnittkanten und der parallel zu der Schamierfaltlinie 13 parallel verlaufenden Schnittkante abgerundet ausgebildet. Der Abstand zwischen der Scharnierfaltlinie 8 bzw. 9 zu der Ausnehmung 27 entspricht ungefähr der Hälfte des Abstandes zwischen der Scharnierfalte 13 und der Ausnehmung 27.In this case, the recess 27 begins at the punched cut 23 and extends to a predetermined extent below the hinge fold 13. The distance between the hinge fold 12 and the recess 27 is preferably greater than the area between the hinge fold line 12 and the punch cut 23. The recess 27 in the Front wall 5 is formed substantially rectangular, and extends parallel to the Schamierfaltelinien 8 and 9 and parallel to the hinge fold 13. Here, the transition between the parallel to the Schamierfalten 8 and 9 running cut edges and parallel to the Schamierfaltlinie 13 parallel cutting edge rounded. The distance between the hinge fold line 8 or 9 to the recess 27 corresponds approximately to half the distance between the hinge fold 13 and the recess 27th

Der Übergang der Ausnehmung 27 in die Aussparungen 28, 29 erfolgt durch eine als Kreisabschnitt ausgebildete Schnittkante, wobei der Bogen zu dem Stanzschnitt konvex ausgebildet ist, so dass zwischen der Ausnehmung 27 und den Aussparungen 28, 29 über einen vorbestimmten Abstand Stegelemente ausgebildet sind.The transition of the recess 27 in the recesses 28, 29 takes place by a trained as a circular section cutting edge, wherein the arc is convex to the punching cut, so that between the recess 27 and the recesses 28, 29 are formed over a predetermined distance web elements.

Sowohl die Seitenwand 4, wie auch die Seitenwand 6 sind mit Durchtrittsöffnungen 30, 31 versehen, die bezüglich der Breite in der Mitte angeordnet sind, bezüglich der Höhe jedoch etwas dem Unterteil zugewandt sind. Die Durchgriffsöffnung ist hierbei als rechteckige Durchgriffsöffnung ausgebildet, wobei die zu der Schamierfaltlinie 13 zugewandten Ecken der Durchgriffsöffnung abgerundet ausgebildet sind. Ausgehend von der unteren, das heißt parallel zu der Scharnierfaltlinie 12 verlaufenden Kante 32 bzw. 33, sind jeweils beginnend an den Ecken Schwächungslinien 34, 35 sowie 36, 37 angeordnet, welche sich zunächst unter einem vorbestimmten Winkel voneinander weg und auf die Schamierfaltlinie 12 zu erstrecken, um schließlich senkrecht zu dieser zu verlaufen. Die Schwächungslinien enden hierbei an einer Position, welche der späteren Trennungslinie entspricht. Im Einsatz lässt sich hier durch einfaches Aufreißen der Schwächungslinien die Ausnehmung 30 bzw. 31 vergrößern.Both the side wall 4, as well as the side wall 6 are provided with passage openings 30, 31, which are arranged with respect to the width in the middle, with respect to the height, however, are slightly facing the lower part. The passage opening is in this case formed as a rectangular passage opening, wherein the edges facing the Schamierfaltlinie 13 of the passage opening are formed rounded. Starting from the lower, that is parallel to the hinge fold line 12 extending edge 32 and 33, respectively beginning at the corners lines of weakness 34, 35 and 36, 37 are arranged, which initially at a predetermined angle away from each other and the Schamierfaltlinie 12 extend to finally run perpendicular to this. The weakening lines end here at a position corresponding to the later dividing line. In use, the recess 30 or 31 can be enlarged here by simply tearing the weakening lines.

Im Folgenden wird unter Zuhilfenahme der Fig. 2 bis 4 der Aufbau und die Funktionsweise der Verpackung aus Karton oder Wellpappe näher erläutert.In the following, the construction and the mode of operation of the packaging made of cardboard or corrugated cardboard will be explained in more detail with the aid of FIGS. 2 to 4.

Der zuvor beschriebene einstückige Zuschnitt wird zunächst im Bereich der Rückwand 3 und der Seitenwand 6 miteinander verklebt und als flachliegende Röhre den weiteren Schritten zugeführt. In dieser Form kann der verklebte Zuschnitt auch als Halbfertigverpackung gelagert werden.The one-piece blank described above is first glued together in the region of the rear wall 3 and the side wall 6 and fed to the further steps as a flat-lying tube. In this form, the glued blank can also be stored as semi-finished packaging.

Wie in Figur 2 dargestellt wird die Halbfertigverpackung zunächst aufgerichtet, so dass die Seitenwände rechtwinklig zueinander angeordnet sind. Anschließend werden die Bodenabschnitte 18, 19, 20 und 21 verschlossen. Hierbei werden vorzugsweise zunächst die der Vorder- und Rückwand zugeordneten Bodenplatten 18 und 20 eingeklappt und anschließend die Bodenklappen 19 und 21. Die solchermaßen verschlossenen Bodenklappen werden miteinander verklebt oder auf andere Weise verschlossen.As shown in Figure 2, the semi-finished package is initially erected, so that the side walls are arranged at right angles to each other. Subsequently, the bottom portions 18, 19, 20 and 21 are closed. In this case, the bottom plates 18 and 20 associated with the front and rear walls are preferably first folded in and then the bottom flaps 19 and 21. The bottom flaps closed in this way are glued together or otherwise closed.

In dem nachfolgenden Schritt wird die Habfertigverpackung in die zwei Teile getrennt, die dann die fertige Verpackung aus Karton oder Wellpappe bilden. Hierzu wird die aufgerichtete Schachtel an Schneidmessern vorbeigeführt, um so die Trennung zwischen Oberteil 1 und Unterteil 2 durchzuführen. Hierbei können runde Schneidmesser eingesetzt werden, die in durch eine mittlere Befestigung beweglich gehalten werden, so dass die Bewegung der Verpackung eine Bewegung der Schneidmesser um die mittlere Befestigung auslöst. Um sicherzustellen, dass während des Trennungsvorganges die zu schneidenden Wände ihre Position beibehalten und um ein kontinuierliches Schneiden zu gewährleisten, wird vor dem Schneidvorgang in die aufgerichtete Halbfertigverpackung ein Formatblock eingeführt, dessen Innenmaße etwas kleiner sind als die Innenmaße der Schachtel. Dieser Formatblock besteht im Bereich der Schnittlinie vorzugsweise aus Hartgummi, so dass die Schneidmesser in den Formatblock eindringen können. Die Halbfertigverpackung kann mittels des Formatblocks durch die Schneideinrichtung gezogen werden.In the subsequent step, the Habfertigverpackung is separated into the two parts, which then form the finished packaging of cardboard or corrugated cardboard. For this purpose, the erected box is guided past cutting knives, so as to prevent the separation between Perform upper part 1 and lower part 2. In this case, round cutting blades can be used, which are held in by a central attachment movable, so that the movement of the packaging triggers a movement of the cutting blade to the central attachment. To ensure that during the separation process, the walls to be cut maintain their position and to ensure continuous cutting, a format block is introduced before the cutting operation in the erect semi-finished packaging, the inner dimensions of which are slightly smaller than the inner dimensions of the box. This format block is preferably made of hard rubber in the region of the cutting line, so that the cutting blades can penetrate into the format block. The semi-finished package can be pulled through the cutter by means of the format block.

Hierbei erleichtern die Ausnehmungen 24, 26, 28 und 29 insbesondere die Verlängerungen der Stanzschnitte 22 und 23, im Bereich der Seitenwand 4 und 6 ein exaktes Positionieren der Schneidmesser. Die Halbfertigverpackung wird an zwei Schneidmessem vorbeigezogen, die einen wellenförmigen Klingenschnitt aufweisen. Hierbei können sowohl nichtangetriebene als auch angetriebene Schneidmesser eingesetzt werden, da die Schachtel selbst bewegt wird. Ferner ist keine genaue Definition der Einschneidetiefe notwendig. Fig. 3 zeigt die Verpackung aus Karton oder Wellpappe nach erfolgter Trennung.Here, the recesses 24, 26, 28 and 29 in particular facilitate the extensions of the punched cuts 22 and 23, in the region of the side wall 4 and 6 an exact positioning of the cutting blade. The semi-finished packaging is drawn past two cutting knives, which have a wave-shaped blade cut. In this case, both non-driven and driven cutting blades can be used, since the box is moved itself. Furthermore, no precise definition of the incision depth is necessary. Fig. 3 shows the packaging of cardboard or corrugated cardboard after separation.

Das von dem Unterteil 2 getrennte Oberteil 1 wird durch den Formatblock so weit in das Unterteil hineingeschoben, dass die unteren Enden der Seitenwände 4, 6 auf der inneren Bodenfläche des Unterteils aufstehen. Hierbei wird durch die Aussparungen 24, 26, 28 und 29 an den Scharnierfaltlinien 7, 8, 9, 10 sowie an der Längskante der Rückwand, welche nach der erfolgten Trennung nunmehr an der unteren Kante des Oberteils liegen, die Breite aller vier Wände 3, 4, 5 und 6 des Oberteils verringert, so dass sie etwas kleiner als die Innenmaße des Unterteils 2 sind. Da die Höhe der Aussparungen 24, 26, 28 und 29 der Höhe des Unterteils entspricht, wird sichergestellt, dass die oberen Enden der Aussparungen an den oberen Ecken des Unterteils aufliegen.The upper part 1 separated from the lower part 2 is pushed into the lower part by the format block so far that the lower ends of the side walls 4, 6 rise on the inner bottom surface of the lower part. Here, by the recesses 24, 26, 28 and 29 at the hinged fold lines 7, 8, 9, 10 and at the longitudinal edge of the rear wall, which are now after the successful separation at the lower edge of the upper part, the width of all four walls 3, 4, 5 and 6 of the upper part are reduced so that they are slightly smaller than the inner dimensions of the lower part 2. Since the height of the recesses 24, 26, 28 and 29 corresponds to the height of the lower part, it is ensured that the upper ends of the recesses rest on the upper corners of the lower part.

Zur Erleichterung des Ineinanderführens des Oberteils 1 und des Unterteils 2 können die Wände 3, 4, 5 und 6 durch von außen angelegte Einrichtungen nach innen gedrückt werden. Hierdurch werden die Außenmaße des Oberteils im Bereich der Aussparungen verringert und das Oberteil lässt sich leicht in das Unterteil einschieben.To facilitate the interfitting of the upper part 1 and the lower part 2, the walls 3, 4, 5 and 6 can be pressed inwards by externally applied devices. As a result, the outer dimensions of the upper part are reduced in the region of the recesses and the upper part can be easily inserted into the lower part.

Sofern das Oberteil und das Unterteil in dem zusammengeschobenen Zustand miteinander verklebt sein sollen, kann das Oberteil vor dem Zusammenschieben mit einem entsprechenden Verbindungsmedium versehen werden. Hier hat sich z.b. Hotmelt als besonders geeignet erwiesen. Vorzugsweise wird das Verbindungsmedium auf die durch die Schwächungslinien 34, 35, 36, 37 abgegrenzten Bereiche 38, 39 unterhalb der Durchgriffsöffnungen 30, 31 aufgebracht. Durch die Schwächungslinien ist es dann einfach möglich, den mit dem Unterteil verbundenen Bereich des Oberteils von dem Oberteil abzutrennen, so dass eine lösbare Verbindung zwischen Oberteil und Unterteil bereitgestellt wird.If the upper part and the lower part are to be glued together in the pushed-together state, the upper part can be provided with a suitable connection medium before being pushed together. Here has z.b. Hotmelt proved to be particularly suitable. The connection medium is preferably applied to the regions 38, 39 defined by the lines of weakness 34, 35, 36, 37 underneath the through openings 30, 31. By the lines of weakness, it is then easily possible to separate the region of the upper part connected to the lower part of the upper part, so that a detachable connection between the upper part and the lower part is provided.

Nachdem das Oberteil 1 und das Unterteil 2 wie beschrieben zusammengeführt worden sind, fährt der Formatblock aus der hergestellten Verpackung aus Karton oder Wellpappe heraus. Die Verpackung aus Karton oder Wellpappe kann dann mit Produkten befüllt werden und wird anschließend mittels der Deckelabschnitte 14, 15, 16, 17 verschlossen. Auch hier kann noch ein zusätzliches Verkleben etc. der Deckelabschnitte erfolgen, um ein sicheres Verschließen zu gewährleisten. Die verschlossene Verpackung aus Karton oder Wellpappe ist in Fig. 4 dargestellt.After the upper part 1 and the lower part 2 have been brought together as described, the format block moves out of the produced cardboard or corrugated cardboard packaging. The packaging made of cardboard or corrugated cardboard can then be filled with products and is then closed by means of the cover sections 14, 15, 16, 17. Here, too, an additional gluing etc. of the lid sections can be done to ensure a secure closing. The sealed package of cardboard or corrugated cardboard is shown in Fig. 4.

Eine andere Ausführungsform der Verpackung aus Karton oder Wellpappe ist in Fig. 5 gezeigt. Hierbei handelt es sich um eine Verpackung, bei welcher das Oberteil 1 nicht in das Unterteil 2 hineingesteckt wird, sondern einen über das Unterteil gestülpten Deckel bildet.Another embodiment of the paperboard or corrugated paperboard package is shown in FIG. This is a packaging in which the upper part 1 is not inserted into the lower part 2, but forms a lid which is slipped over the lower part.

Bei dieser Ausführungsform stimmt die Herstellung bis zur Trennung des Oberteils und des Unterteils mit der zuvor beschriebenen Ausführungsform überein. Anschließend wird das Oberteil mittels des Formatblocks über das Unterteil geschoben. Bei dieser Ausführungsform hat es sich als besonders geeignet erwiesen, wenn das Unterteil im Bereich der Scharnierfaltkantlinien mit Aussparungen versehen ist, und die unteren Ecken der Aussparungen des Unterteils auf den unteren Ecken des Oberteils aufliegen. Ferner wird hierbei das Unterteil mit dem Verbindungsmedium versehen, so dass im Bereich des Unterteiles entsprechende Schwächungslinien ausgebildet sind.In this embodiment, the manufacture until the separation of the upper part and the lower part coincides with the embodiment described above. Subsequently, the upper part is pushed over the lower part by means of the format block. In this embodiment, it has proven to be particularly suitable when the lower part is provided in the region of the hinged folded edge lines with recesses, and the lower corners of the recesses of the lower part rest on the lower corners of the upper part. Furthermore, in this case the lower part is provided with the connecting medium, so that in the region of the lower part corresponding weakening lines are formed.
