Description

Die Erfindung bezieht sich auf eine Verpackung aus Karton oder dergleichen für einen oder mehrere becherförmige mit Flanschrand versehene Behälter, mit einer Deckfläche, zwei Seitenwänden sowie einer Bodenfläche, die jeweils über Faltlinien miteinander verbunden sind, wobei an der einen Seitenwand ein Lappen über eine Faltlinie angelenkt ist, der zum Verbinden dieser Seitenwand mit der Deckfläche dient.The invention relates to a packaging made of cardboard or the like for one or more cup-shaped flanged containers, with a top surface, two side walls and a bottom surface, each of which is connected to one another via fold lines, a flap articulated on one side wall via a fold line is used to connect this side wall to the top surface.

Im allgemeinen wird zum Verschließen der Verpackung die Deckfläche mit dem Lappen verklebt, wodurch ein sehr zuverlässiger Verschluß gebildet wird.In general, the cover surface is glued to the rag to seal the package, thereby forming a very reliable seal.

Aus der US-A-3 014 636 ist es darüber hinaus bekannt, an der Deckfläche Ansätze anzuformen, die in Ausnehmungen eingreifen und sich dort verhaken. Diese Ansätze sind beiderseits mit hakenförmigen Vorsprüngen versehen um dieses Verhaken zu ermöglichen. Dadurch ist aber das Einführen der Ansätze in die Ausnehmungen sehr schwierig und es ist eine spezielle Ausgestaltung der Ausnehmungen notwendig.From US-A-3 014 636 it is also known to form lugs on the top surface which engage in recesses and get caught there. These approaches are provided on both sides with hook-shaped projections to enable this hooking. As a result, however, the insertion of the lugs into the recesses is very difficult and a special configuration of the recesses is necessary.

Der Erfindung liegt die Aufgabe zugrunde, die Verpackung der eingangs genannten Art so auszugestalten, daß ein einfaches und trotzdem sicheres Verschließen ermöglicht wird.The invention has for its object to design the packaging of the type mentioned so that a simple, yet secure closing is made possible.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in der zwischen der einen Seitenwand und dem Lappen vorgesehenen Faltlinie Öffnunen vorgesehen sind, in welche Ansätze einzugreifen vermögen, welche an der freien Kante der Deckfläche über eine Anlenk-Faltlinie angeordnet sind, wobei diese Ansätze durch eine weitere Faltlinie in zwei Abschnitte unterteilt sind, von denen sich der freie Abschnitt unter dem Flanschrand der Behälter abstützt.This object is achieved in that openings are provided in the fold line provided between the one side wall and the flap, in which approaches are able to intervene, which are arranged on the free edge of the top surface via a hinged fold line, these approaches being followed by a further one Fold line are divided into two sections, of which the free section is supported under the flange edge of the container.

Zum Einstecken dieser Ansätze in die Öffnungen müssen die Ansätze lediglich zusammengedrückt werden und lassen sich dann einfach in die völlig geraden Öffnungen einschieben.To insert these lugs into the openings, the lugs only have to be pressed together and can then simply be pushed into the completely straight openings.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die die Ansätze unterteilende Faltlinie parallel zur Anlenk-­Faltlinie verläuft.It is also very advantageous if, according to the invention, the fold line dividing the approaches runs parallel to the articulated fold line.

Ein so ausgebildeter Ansatz geht beim Einschieben in die Ausnehmung nach einer entsprechenden Vorfaltung selbsttätig zusammen und nach dem Durchtreten durch die Ausnehmung wieder auseinander, so daß zum Verschließen keine weiteren Hilfsmittel notwendig sind.Such an approach goes automatically when inserted into the recess after a corresponding pre-folding and apart again after passing through the recess, so that no further aids are necessary for closing.

Erfindungsgemäß ist es aber auch möglich, daß die die Ansätze unterteilende Faltlinie in einem Winkel α zur Anlenk-Faltlinie verläuft, der etwas weniger als 90° beträgt.According to the invention, however, it is also possible for the fold line dividing the approaches to extend at an angle α to the articulated fold line which is somewhat less than 90 °.

So ausgebildete Ansätze müssen zwar während des Einschiebens in die entsprechende Öffnung zusammengedrückt werden, dafür ergeben sie aber einen noch besseren Halt.Approaches designed in this way have to be pressed together during the insertion into the corresponding opening, but in return they result in an even better hold.

Als ebenfalls sehr günstig hat es sich ergeben, wenn erfindungsgemäß am freien Abschnitt des Ansatzes ein Vorsprung angeformt ist, mit dem sich der Ansatz seitlich am Flanschrand des Behälters abstützt, während die übrige Kante des Ansatzes an der Unterseite des Flanschrandes anliegt.It has also been found to be very favorable if, according to the invention, a projection is formed on the free section of the attachment, with which the attachment is located laterally is supported on the flange edge of the container, while the remaining edge of the attachment rests on the underside of the flange edge.

Dieser Vorsprung vermittelt dem Ansatz einen hervorragenden Halt am Flanschrand, so daß der Verschluß sehr sicher wird.This projection gives the approach an excellent grip on the flange edge, so that the closure is very secure.

Die Erfindung wird nachfolgend anhand von vier in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert. Dabei zeigen:

Wie aus Fig.1 ersichtlich, besteht die Verpackung 100 aus einer Deckfläche 110 und einer mit einer Faltlinie 112 daran angelenkten ersten Seitenwand 120, einer Bodenfläche 140, die mit der ersten Seitenwand 120 über eine Faltlinie 124 und mit einer zweiten Seitenwand 130 über eine Faltlinie 134 verbunden ist, sowie aus einem Lappen 150, der über eine Faltlinie 135 an der zweiten Seitenwand 130 angelenkt ist.As can be seen from FIG. 1, the packaging 100 consists of a cover surface 110 and a first side wall 120 hinged to it with a fold line 112, a bottom surface 140 which connects to the first side wall 120 via a fold line 124 and with a second side wall 130 via a fold line 134 is connected, as well as from a tab 150 which is articulated on the second side wall 130 via a fold line 135.

Die Bodenfläche 140 besitzt drei Teilflächen 140a, 140b und 140C, getrennt durch Faltlinien 144 und 145.The bottom surface 140 has three partial surfaces 140a, 140b and 140C, separated by fold lines 144 and 145.

In den Teilflächen 140b und 140c der Bodenfläche 140 befinden sich halbmondförmige Öffnungen 146, die dazu bestimmt sind, in die Verpackung eingestellte Behälter PB im unteren Bereich zu fixieren.In the partial surfaces 140b and 140c of the bottom surface 140 there are crescent-shaped openings 146 which are intended to fix containers P B placed in the packaging in the lower region.

Der Lappen 150 dient zum Verbinden der Seitenwand 130 mit der Deckfläche 11O. In der zwischen der Seitenwand 130 und dem Lappen 150 vorgesehenen Faltlinie 135 sind Öffnungen 210 vorgesehen. Im flachliegenden Kartonzuschnitt gemäß Fig.1 sind die Öffnungen 210 als eingestanzte Schlitze ausgebildet, die beim Aufrichten der Verpackung jeweils Ausnehmungen freilegen.The tab 150 serves to connect the side wall 130 to the top surface 110. Openings 210 are provided in the fold line 135 provided between the side wall 130 and the tab 150. In the flat cardboard blank according to FIG. 1, the openings 210 are formed as punched-in slots which expose recesses when the packaging is erected.

An der freien Kante 111 der Deckfläche 110 sind drei identische Ansätze 220 über eine Anlenk-Faltlinie 221 derart angelenkt, daß sie gleichmäßig über die Verpackung 100 verteilt sind und in die Öffnungen 210 einzugreifen vermögen.At the free edge 111 of the top surface 110, three identical lugs 220 are articulated via a hinged folding line 221 in such a way that they are evenly distributed over the packaging 100 and are able to engage in the openings 210.

Entsprechend dem ersten Ausführungsbeispiel sind die Ansätze 220 durch eine Faltlinie 222 in zwei Abschnitte 220a und 220b unterteilt, wobei der freie Abschnitt 220b zusätzlich einen Vorsprung 220c aufweist. Der Abschnitt 220a erstreckt sich zwischen der Anlenk-Faltlinie 221, die einen Teil der Kante 111 ausmacht, und der Faltlinie 222, während sich der Abschnitt 220b zwischen der Faltlinie 222 und der äußeren Kante 223 der Ansätze 220 erstreckt, die parallel zu der Anlenk-Faltlinie 221 und der Faltlinie 222 verläuft. Die Längen La und Lb der Abschnitte 220a und 220b sind genau festgelegt, wie später noch zu sehen ist. Auch die Länge Lc des Vorsprungs 220c ist genau festgelegt, während seine Breite kleiner ist als die der Ansätze 220 an dieser Stelle.According to the first embodiment, the lugs 220 are divided into two sections 220a and 220b by a fold line 222, the free section 220b additionally having a projection 220c. Section 220a extends between the hinge fold line 221, which forms part of the edge 111, and the fold line 222, while the section 220b extends between the hinge line 222 and the outer edge 223 of the lugs 220, which is parallel to the hinge line. Fold line 221 and fold line 222 runs. The lengths La and Lb of sections 220a and 220b are precisely defined, as will be seen later. The length Lc of the projection 220c is also precisely defined, while its width is smaller than that of the lugs 220 at this point.

Im vorliegenden Ausführungsbeispiel haben die Ansätze 220 eine sich über ihre Länge verändernde Breite, wobei sie im Bereich der Anlenk-Faltlinien 221 und der äußeren Kante 223 eine maximale Breite und im Bereich der Faltlinie 222 eine minimale Breite haben, so daß die Abschnitte 220a und 220b die Gestalt von zwei Trapezen aufweisen.In the present exemplary embodiment, the lugs 220 have a width that changes over their length, wherein they have a maximum width in the region of the articulation fold lines 221 and the outer edge 223 and a minimum width in the region of the fold line 222, so that the sections 220a and 220b have the shape of two trapezoids.

Die vorgenannte maximale Breite der Ansätze 220 ist vorzugsweise gleich oder nur wenig kleiner als die Länge der Öffnungen 210.The aforementioned maximum width of the lugs 220 is preferably the same or only slightly less than the length of the openings 210.

Schließlich besitzt die Verpackung gemäß Fig.1 im Lappen 150 zusätzliche Befestigungsmittel in Form von Lappen 300, welche von oben her zwischen zwei benachbarte Behälter PH eingreifen.Finally, the packaging according to FIG. 1 has additional fastening means in the form of tab 300 in the form of tab 300, which engage from above between two adjacent containers P H.

Der in Fig.1 dargestellte Kartonzuschnit ist zum Verpacken von zwölf Behältern vorgesehen, die in zwei Etagen angeordnet werden.The cardboard blank shown in Fig.1 is intended for packaging twelve containers, which are arranged on two levels.

In Fig.2 ist eine Verpackung im aufgerichteten, noch nicht verschlossenen Zustand dargestellt, wobei jedoch anstatt der drei Ansätze 220, entsprechend Fig.1, nur zwei Ansätze 220 vorgesehen sind.2 shows a packaging in the erected, not yet closed state, but instead of of the three approaches 220, corresponding to FIG. 1, only two approaches 220 are provided.

Bezugnehmend auf Fig.2 ist die Verpackung 100 für acht Behälter ausgebildet, die in zwei Etagen angeordnet sind. In der unteren Etage sind die Behälter mit PB und in der oberen Reiche mit PH bezeichnet. Die Behälter der selben Etage sind im Viereck aufgestellt und miteinander in Höhe des Flanschrandes CH bzw. CB verbunden.With reference to FIG. 2, the packaging 100 is designed for eight containers which are arranged on two levels. On the lower level, the containers are labeled P B and on the upper level, P H. The containers on the same floor are set up in a square and connected to each other at the flange edge C H or C B.

Zum Aufrichten und Verschließen der Verpackung 100 bleibt die Teilfläche 140a der Bodenfläche 140 horizontal liegen, die Teilflächen 140b und 140c werden um ca.45o zur Horizentalen geneigt, die Teilflächen 120b und 130b nahezu vertikal und die Teilflächen 120a und 130a vertikal nach oben gefaltet. Die Deckfläche 110 wird in waagerechte Richtung um die Faltlinie 112 derart gefaltet, daß der ebenfalls waagerecht gefaltete Lappen 150 überdeckt wird (Fig.2).For erecting and closing the package 100, the sub-area remains 140a of the bottom surface of lie horizontally 140, the surface portions 140b and 140c are at approximately 45 o inclined to Horizentalen, the surface portions 120b and 130b almost vertically and the surface portions 120a and 130a vertically folded upward. The cover surface 110 is folded in the horizontal direction around the fold line 112 such that the flap 150, which is also folded horizontally, is covered (FIG. 2).

Entsprechend Fig.3 werden die Ansätze 220 so gefaltet, daß der Abschnitt 220a um ca.90° nach unten zeigt und der Abschnitt 220b zusammen mit dem Vorsprung 220c innen in Bezug auf den Abschnitt 220a befindet. Dabei bildet sich zwischen Abschnitt 220a und Abschnitt 220b ein spitzer Winkel.According to FIG. 3, the lugs 220 are folded such that the section 220a points downward by approximately 90 ° and the section 220b together with the projection 220c is located in relation to the section 220a. An acute angle is formed between section 220a and section 220b.

Beim Schließen der Verpackung wird die Deckfläche 110 in die Horizontale gebracht und gleichzeitig die Ansätze 220 in die entsprechenden Öffnungen 210 geschoben. Dabei werden die Abschnitte 220a und 220b gegeneinander gedrückt.When the packaging is closed, the top surface 110 is brought into the horizontal and at the same time the lugs 220 are pushed into the corresponding openings 210. The sections 220a and 220b are pressed against each other.

Die Fig.4 und 5 zeigen die Verpackung 100 im geschlossenen Zustand. Nachdem die Ansätze 220b in die Öffnungen 210 eingeführt sind, geht der Abschnitt 220b jedes Ansatzes 220 vom Abschnitt 220a nach innen weg. Bei dieser Bewegung um die Faltlinie 222, verursacht durch die Elastizität des verwendeten Materials, legt sich der Vorsprung 220c, der sich in der Höhe des Flanschrandes CH des Behälters PH befindet, an den äußeren Rand des Flanschrandes CH, während der Abschnitt 220b mit der Kante 223 unter den Flanschrand CH gleitet.4 and 5 show the packaging 100 in the closed state. After tabs 220b are inserted into openings 210, section 220b of each tab 220 goes inward from section 220a. During this movement around the fold line 222, caused by the elasticity of the material used, the projection 220c, the is located at the level of the flange edge C H of the container P H , to the outer edge of the flange edge C H , while the section 220b slides with the edge 223 under the flange edge C H.

Wie Fig.5 zeigt, nimmt der Abschnitt 220b jedes Ansatzes 220 eine schräge Stellung ein, wobei er mit seinem Vorsprung 220c am Rand des Flanschrandes CH bleibt und unter den Flanschrand CH rutscht. Die maximale Abspreizung richtet sich dabei nach dem Abstand zwischen der Wand des Behälters PH und der Seitenwand 130a.As FIG. 5 shows, the section 220b of each extension 220 assumes an inclined position, its projection 220c remaining at the edge of the flange edge C H and sliding under the flange edge C H. The maximum spread depends on the distance between the wall of the container P H and the side wall 130a.

Die Vorzüge der Verpackung werden dadurch erreicht, daß die bereits weiter oben genannten Abmessungen entsprechend der Stärke e des Kartons oder ähnlicher Verpackungsmaterialien und der Dicke Ld des Flanschrandes CH vorzugsweise wie folgt gewählt werden:
(1) La - Lb ≈ Ld + e
(2) Lc ≦ LdThe advantages of the packaging are achieved in that the dimensions already mentioned above are preferably selected as follows according to the thickness e of the cardboard or similar packaging materials and the thickness Ld of the flange edge C H :
(1) La - Lb ≈ Ld + e
(2) Lc ≦ Ld

Im folgenden werden, bezugnehmend auf die Fig.6 bis 9, drei weitere Ausführungsbeispiele beschrieben. Gleiche oder ähnliche Teile mit den gleichen Bezugszeichen werden nicht nochmals erklärt.Three further exemplary embodiments are described below with reference to FIGS. 6 to 9. The same or similar parts with the same reference symbols are not explained again.

Bei dem in Fig.6 dargestellte Ausführungsbeispiel werden Behälter mit einem geringen Flanschrand CH verwendet. Deshalb wurde hier der Vorsprung 220c weggelassen, so daß sich der Abschnitt 220b des Ansatzes 220 mit seiner Kante 223 völlig unter den Flanschrand CH schieben kann.In the embodiment shown in FIG. 6, containers with a small flange edge C H are used. Therefore, the protrusion 220c is omitted here, so that the portion can slide 220b of the projection 220 with its edge 223 completely under the flange C H.

Die Erfindung eignet sich auch, wie in dem in Fig.7 dargestellten dritten Ausführungsbeispiel gezeigt, für Behälter ohne Flanschrand CH. Der Ansatz 220 besitzt, wie in Fig.6, ebenfalls keinen Vorsprung 220c. Beim Verschließen der Verpackung 100 drückt die Kante 223 des Abschnittes 220b gegen die untere Fläche des Lappens 150. Hier muß darauf geachtet werden, daß ein genügend großer Zwischenraum d zwischen der Wand des Behälters PH und der Teilfläche 130a der Seitenwand 130 gewährleistet ist, um zu verhindern, daß der Abschnitt 220b nicht in Richtung der Öffnung 210 zurückfedert und sich dadurch die Verpackung öffnet.The invention is also suitable, as shown in the third exemplary embodiment shown in FIG. 7, for containers without a flange edge C H. The approach 220, as in FIG. 6, likewise has no projection 220c. When the packaging 100 is closed, the edge 223 of the Section 220b against the lower surface of the flap 150. Here it must be ensured that a sufficiently large clearance d is ensured between the wall of the container P H and the partial surface 130a of the side wall 130 in order to prevent the section 220b from not moving in the direction springs back of the opening 210 and thereby opens the packaging.

Bei diesem Ausführungsbeispiel wird die Gleichung (1) ersetzt durch:
(1′) La - Lb ≈ eIn this embodiment, equation (1) is replaced by:
(1 ′) La - Lb ≈ e

Die Fig.8 und 9 zeigen ein viertes Ausführungsbeispiel der Erfindung. Hierbei besitzen die Ansätze 220 einen ersten Abschnitt 220a, der mittels einer Anlenk-Faltlinie 221 mit der Deckfläche 110 verbunden ist, und einen zweiten Abschnitt 220b, der über eine Faltlinie 222 am ersten Abschnitt 220a angelenkt ist und dabei mit diesem einen Winkel α bildet, der etwas weniger als 90° beträgt. Beim flachliegenden Kartonzuschnit (Fig.8) befindet sich also der Abschnitt 220b seitlich am ersten Abschnitt 220a. Die Kante 223 verläuft als abgewinkelte Verlängerung der Anlenk-Faltlinie 221 und bildet einen Winkel ß, der dem Doppelten der Differenz 90° - α entspricht.8 and 9 show a fourth embodiment of the invention. Here, the lugs 220 have a first section 220a, which is connected to the cover surface 110 by means of an articulated folding line 221, and a second section 220b, which is articulated on the first section 220a via a folding line 222 and thereby forms an angle α with it, which is a little less than 90 °. In the case of the cardboard blank lying flat (FIG. 8), the section 220b is located laterally on the first section 220a. The edge 223 runs as an angled extension of the articulation folding line 221 and forms an angle β which corresponds to twice the difference 90 ° - α.

Die Abschitte 220b werden gegen die Abschnitte 220a nach innen gefaltet und die Ansätze 220 in die Öffnungen 210 eingeführt. Sobald die Ansätze 220 in die Öffnungen 210 eingeführt sind, bewegen sich die Abschnitte 220b aufgrund der Elastizität des Materials um die Faltlinie 222 und lösen sich somit leicht vom Abschnitt 220a, wie es in Fig.9 gezeigt ist. Bei diesem Ausführungsbeispiel verankert sich die Kante 223 des Abschnittes 220b unter dem Lappen 150.The sections 220b are folded inward against the sections 220a and the lugs 220 are inserted into the openings 210. Once the tabs 220 are inserted into the openings 210, the sections 220b move about the fold line 222 due to the elasticity of the material and thus easily detach from the section 220a, as shown in FIG. In this embodiment, the edge 223 of the portion 220b anchors under the tab 150.

Es ist gleichfalls möglich, dieses Ausführungsbeispiel zur Verpackung von Behältern mit Flanschrand CH einzusetzen. In diesem Fall wird die Kante 223 vom der Anlenk-Faltlinie 221 zurückgesetzt und zwar um die Dicke Ld des Flanschrandes CH. Die Kante 223 verankert sich dann unter dem Flaschrand CH.It is also possible to use this embodiment for packaging containers with a flange edge C H. In this case, the edge 223 is from the hinge fold line 221 reset by the thickness Ld of the flange edge C H. The edge 223 then anchored under the Flaschrand C H.

Die Erfindung ist gleichfalls für Behälter mit ähnlicher Ausstattung, wie sie beschrieben sind, einsetzbar.The invention can also be used for containers with similar equipment as described.

Die Verpackung kann aus Karton hergestellt werden, aber auch aus jedem anderen Material, das die Elastizität aufweist, die erforderlich ist, um die Abschnitte 220b jedes Ansatzes 220 in die notwendige Verschlußstellung zu bringen.The packaging can be made from cardboard, but also from any other material that has the elasticity required to bring the sections 220b of each lug 220 into the necessary closed position.

Wenn auch in den beschriebenen Ausführungsbeispielen die Anzahl der Ansätze 220 gleich der Anzahl der in Längsrichtung angeordneten Behälter ist und die Verschlüsse sich jeweils senkrecht zu den Behältern befinden, ist es gleichfalls möglich, die Ansätze 220 in beliebiger Anzahl zu wählen und die Verschlüsse an Überlappungen von beliebigen Flächen der Verpackung anzubringen.If, in the exemplary embodiments described, the number of lugs 220 is equal to the number of containers arranged in the longitudinal direction and the closures are each perpendicular to the containers, it is also possible to select the lugs 220 in any number and the closures to overlap from attach any surface of the packaging.
