Abstract

It is often difficult to empty prior art collapsible package if the contents are viscous or in cream or paste form. It is therefore proposed according to the invention to provide an outer carton (2) and an inner pouch (3) in which the inner pouch can be emptied through a pouring stub (32). The bottom end (9) opposite the pouring stub is secured to only two side-walls. These two side-walls can therefore be pressed together, whereupon the bottom bends inwards and the other side-walls outwards. It is thus possible to press out even substances in cream of paste form.

Description

Die Erfindung bezieht sich auf eine Tube aus Karton nach dem Oberbegriff des Patentanspruches 1.The invention relates to a tube made of cardboard according to the preamble of claim 1.

Derartige Verpackungen sind zwar gut geeignet zum Transportieren und Ausgießen von Schüttgütern, wie einerseits pulvrige Stoffe und andererseits Flüssigkeiten. Wenn das in der Verpackung aufzubewahrende Material jedoch eine große Viskosität aufweist oder gar creme- oder pastenartig ist, besteht bei der eingangs beschriebenen Verpackung das Problem, daß das Material nicht gut aus der Verpackung ausgeleert werden kann.Such packaging is indeed well suited for transporting and pouring bulk materials, such as powdery materials on the one hand and liquids on the other. However, if the material to be stored in the packaging has a high viscosity or is even creamy or pasty-like, the problem with the packaging described at the outset is that the material cannot be emptied well from the packaging.

Aus der EP-A-0 225 677 ist ein Behälter mit den Merkmalen des Oberbegriffes des Patentanspruches 1 bekannt. Dieser Behälter weist die oben beschriebenen Nachteile auf, daß nämlich creme- oder pastenartige Materialien nur schwer entleert werden können.From EP-A-0 225 677 a container with the features of the preamble of claim 1 is known. This container has the disadvantages described above, namely that cream or paste-like materials can be emptied only with difficulty.

Aus der EP-A-0 172 711 ist eine Verpackung bekannt, bei der ein Außenbehälter mit einem darin vorgesehenen Innenbehälter zusammendrückbar ist zum Austreiben des Behälterinhaltes.From EP-A-0 172 711 a package is known in which an outer container with an inner container provided therein can be compressed to expel the contents of the container.

Es ist daher die der Erfindung zugrunde liegende Aufgabe, eine Kartontube der eingangs beschriebenen Art derart zu verbessern, daß auch creme- und pastenartige Materialien aus der Verpackung leicht entnommen werden können.It is therefore the object of the invention to improve a cardboard tube of the type described above in such a way that creamy and pasty materials can also be easily removed from the packaging.

Diese Aufgabe wird durch eine Tube aus Karton der eingangs beschriebenen Art gelöst, die durch die Merkmale des kennzeichnenden Teiles des Patentanspruches 1 gekennzeichnet ist.This object is achieved by a tube made of cardboard of the type described above, which is characterized by the features of the characterizing part of patent claim 1.

Da die Rückwand nur mit zwei Seitenwänden verbunden ist, während mindestens eine Seitenwand keine Verbindung mit der Rückwand hat, können die beiden mit der Rückwand verbundenen Seitenwände zusammengedruckt werden. Die nicht mit der Rückwand verbundene Seitenwand kann nach außen ausweichen. Daher läßt sich die gesamte Verpackung zusammendrücken. Damit sind auch Creme- und pastenartige Stoffe aus der Verpackung herauszudrücken.Since the rear wall is only connected to two side walls, while at least one side wall has no connection to the rear wall, the two side walls connected to the rear wall can be printed together. The side wall not connected to the rear wall can move outwards. Therefore, the entire packaging can be compressed. This means that cream and paste-like substances can also be pressed out of the packaging.

Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Preferred developments of the invention are characterized in the subclaims.

Wenn die Rückwand zwischen den Seitenwänden, mit denen sie verbunden ist., eine etwas größere Ausdehnung hat, so muß sie sich entweder in die Verpackung hineinwölben oder aus ihr herauswölben. Dadurch wird das Zusammendrucken der Verpackung noch weiter erleichtert. Wenn sie sich insbesondere in die Verpackung hineinwölbt, wird sichergestellt, daß der Innenbeutel zuverlässig in der Verpackung bleibt. Knicklinien unterstützen vorteilshafterweise das Zusammendrücken der Verpackung.If the rear wall between the side walls to which it is connected has a somewhat larger extension, it must either bulge into the packaging or bulge out of it. This makes it even easier to print the packaging together. If it bulges particularly into the packaging, it is ensured that the inner bag remains reliably in the packaging. Kink lines advantageously support the compression of the packaging.

Weitere Vorteilhafte Merkmale und Zweckmäßigkeiten der Erfindung ergeben sich aus der Beschreibung von Ausführungsbeispielen anhand der Figuren. Von den Figuren zeigen:

Wie am besten aus Fig. 3 zu sehen ist, weist die Tube aus Karton einen äußeren Karton 2 und einen Innenbeutel 3 auf.As can best be seen from FIG. 3, the cardboard tube has an outer carton 2 and an inner bag 3.

Der Karton 2 wird aus dem in Figur 1 gezeigten Zuschnitt 4 gebildet. Der Zuschnitt 4 weist eine erste Seitenwand 5 und eine zweite Seitenwand 6 auf. Zwischen der ersten Seitenwand 5 und der zweiten Seitenwand 6 ist eine dritte Seitenwand vorgesehen. An der der dritten Seitenwand 7 abgewandten Seite der ersten Seitenwand 5 ist eine vierte Seitenwand 8 vorgesehen.The carton 2 is formed from the blank 4 shown in FIG. 1. The blank 4 has a first side wall 5 and a second side wall 6. A third side wall is provided between the first side wall 5 and the second side wall 6. A fourth side wall 8 is provided on the side of the first side wall 5 facing away from the third side wall 7.

An der hinteren Seite der ersten Seitenwand 5 (in Fig. 1 die untere Seite) ist eine Rückwand 9 vorgesehen. Die Rückwand 9 erstreckt sich im wesentlichen über die volle Breite der ersten Seitenwand 5. Die Höhe der Rückwand 9, d.h. die Ausdehnung, mit der sich die Rückwand 9 von der ersten Seitenwand 5 wegerstreckt, ist etwas größer als die Breite der dritten Seitenwand 7 bzw. der vierten Seitenwand 8.A rear wall 9 is provided on the rear side of the first side wall 5 (the lower side in FIG. 1). The rear wall 9 extends essentially over the full width of the first side wall 5. The height of the rear wall 9, i.e. the extent with which the rear wall 9 extends away from the first side wall 5 is somewhat larger than the width of the third side wall 7 or the fourth side wall 8.

An der unteren Seite der zweiten Seitenwand 6 ist ein Klebestreifen 10 vorgesehen. An der der ersten Seitenwand 5 abgewandten Seite der vierten Seitenwand 8 ist ein Klebestreifen 11 vorgesehen.An adhesive strip 10 is provided on the lower side of the second side wall 6. An adhesive strip 11 is provided on the side of the fourth side wall 8 facing away from the first side wall 5.

An der Vorderseite der ersten Seitenwand 5 (in Fig. 1 die obere Seite) ist eine erste Abdeckplatte 12 vorgesehen. Die Abdeckplatte 12 erstreckt sich im wesentlichen über die gesamte Breite der ersten Seitenwand 5. Die Höhe der ersten Abdeckplatte 12 entspricht im wesentlichen der Breite der dritten Seitenwand 7 bzw. der vierten Seitenwand 8. An der der ersten Seitenwand 5 abgewandten Seite der Deckplatte 12 ist eine Klebelasche 13 vorgesehen. An den beiden Seiten der Abdeckplatte 12 sind zwei dreieckige Klebelaschen 14 und 15 vorgesehen.A first cover plate 12 is provided on the front of the first side wall 5 (the upper side in FIG. 1). The cover plate 12 extends essentially over the entire width of the first side wall 5. The height of the first cover plate 12 corresponds essentially to the width of the third side wall 7 or the fourth side wall 8. On the side of the cover plate 12 facing away from the first side wall 5 an adhesive tab 13 is provided. Two triangular adhesive tabs 14 and 15 are provided on both sides of the cover plate 12.

An der Vorderseite der zweiten Seitenwand 6 ist eine zweite Abdeckplatte 16 vorgesehen. Die zweite Abdeckplatte 16 erstreckt sich im wesentlichen über die volle Breite der zweiten Seitenwand 6. Ihre Höhe entspricht im wesentlichen der Breite der dritten Seitenwand 7 bzw. der vierten Seitenwand 8.A second cover plate 16 is provided on the front of the second side wall 6. The second cover plate 16 extends essentially over the full width of the second side wall 6. Its height corresponds essentially to the width of the third side wall 7 or the fourth side wall 8.

Die Rückwand 9 weist eine Knicklinie 17 auf. Die Knicklinie 17 erstreckt sich im wesentlichen parallel zu der Unterseite der ersten Seitenwand 5. Sie verläuft im wesentlichen im halben Abstand der Höhe der Rückwand 9 von der Unterseite der zweiten Seitenwand 5.The rear wall 9 has a crease line 17. The kink line 17 extends essentially parallel to the underside of the first side wall 5. It runs essentially half the distance of the height of the rear wall 9 from the underside of the second side wall 5.

Die 1. - 4. Seitenwand 5-8 weisen eine Knicklinie 18, 19, 20 bzw. 21 auf. Die Knicklinien 18-21 verlaufen im wesentlichen parallel zu den Vorderseiten ihrer entsprechenden Seitenwände. Der Abstand zu den Vorderseiten beträgt etwa die halbe Breite der dritten Seitenwand 7 bzw. vierten Seitenwand 8.The 1st - 4th side walls 5-8 have a crease line 18, 19, 20 and 21 respectively. The crease lines 18-21 are substantially parallel to the front of their respective side walls. The distance from the front sides is approximately half the width of the third side wall 7 or fourth side wall 8.

In der dritten Seitenwand 7 ist eine Schwächungslinie 22 angebracht. Die Schwächungslinie erstreckt sich von der Hinterseite bis zu der Knicklinie 20. Die Schwächungslinie 22 verläuft im wesentlichen parallel zu den Seitenkanten und im wesentlichen in gleichen Abständen zu der rechten und linken Seitenkante.A line of weakness 22 is attached in the third side wall 7. The line of weakness extends from the rear to the crease line 20. The line of weakness 22 extends substantially parallel to the side edges and at substantially equal distances from the right and left side edges.

Eine entsprechende Schwächungslinie 23 ist in der vierten Seitenwand 8 vorgesehen. Auch die Schwächungslinie 23 erstreckt sich im wesentlichen von der Hinterseite bis zu der Knicklinie 21. Sie ist im wesentlichen parallel zu den Seitenkanten und im gleichen Abstand zu beiden Seitenkanten.A corresponding line of weakness 23 is provided in the fourth side wall 8. The weakening line 23 also extends essentially from the rear side to the crease line 21. It is essentially parallel to the side edges and at the same distance from both side edges.

In der dritten Seitenwand 7 ist eine weitere Schwächungslinie 24 vorgesehen. Die Schwächungslinie 24 erstreckt sich von dem Punkt, an dem die Schwächungslinie 22 auf die Knicklinie 20 auftrifft, zu dem vorderen Verbindungspunkt zwischen der ersten Seitenwand 5 und der dritten Seitenwand 7.A further weakening line 24 is provided in the third side wall 7. The weakening line 24 extends from the point at which the weakening line 22 meets the fold line 20 to the front connection point between the first side wall 5 and the third side wall 7.

Eine entsprechende Schwächungslinie 25 ist in der vierten Seitenwand 8 vorgesehen. Sie erstreckt sich von dem Punkt, an dem die Schwächungslinie 23 auf die Knicklinie 21 stößt, zu dem vorderen Verbindungspunkt zwischen der ersten Seitenwand 5 und der vierten Seitenwand 8. Die Schwächungslinien 24 bzw. 25 setzen sich gradlinig als Schwächungslinien 26 und 27 in die erste Abdeckplatte 12 fort. Sie erstrecken sich im wesentlichen bis in die Mitte der Abdeckplatte 12.A corresponding weakening line 25 is provided in the fourth side wall 8. It extends from the point at which the weakening line 23 abuts the kink line 21 to the front connection point between the first side wall 5 and the fourth side wall 8. The weakening lines 24 and 25 form a straight line as weakening lines 26 and 27 in the first cover plate 12 continues. They extend essentially to the middle of the cover plate 12.

In der zweiten Abdeckplatte 16 sind ebenfalls Schwächungslinien 28 und 29 vorgesehen. Die Schwächungslinien 28 und 29 sind spiegelsymmetrisch zu den Schwächungslinien 26 und 27 angeordnet, d.h. sie erstrecken sich also von den oberen Ecken der Abdeckplatte 16 bis im wesentlichen in die Mitte der Abdeckplatte 16.Lines of weakness 28 and 29 are also provided in the second cover plate 16. The weakening lines 28 and 29 are arranged mirror-symmetrically to the weakening lines 26 and 27, i.e. they therefore extend from the upper corners of the cover plate 16 to substantially the middle of the cover plate 16.

Die dritte Seitenwand 7 weist eine Knicklinie 30 auf. Die Knicklinie 30 erstreckt sich von dem Punkt, an dem die Schwächungslinie 22 auf die Knicklinie 20 stößt zu dem vorderen Verbindungspunkt zwischen der dritten Seitenwand 7 und der zweiten Seitenwand 6. Sie ist daher symmetrisch zu der Schwächungslinie 24.The third side wall 7 has a crease line 30. The fold line 30 extends from the point at which the weakening line 22 abuts the fold line 20 to the front connection point between the third side wall 7 and the second side wall 6. It is therefore symmetrical to the weakening line 24.

Die vierte Seitenwand 8 weist eine Knicklinie 31 auf. Die Knicklinie 31 erstreckt sich von dem Punkt, an dem die Schwächungslinie 23 auf die Knicklinie 21 stößt, zu dem vorderen Verbindungspunkt zwischen der vierten Seitenwand 8 und dem Klebestreifen 11. Die Knicklinie 31 ist daher symmetrisch zu der Schwächungslinie 25.The fourth side wall 8 has a crease line 31. The crease line 31 extends from the point at which the weakening line 23 meets the crease line 21 to the front connection point between the fourth side wall 8 and the adhesive strip 11. The crease line 31 is therefore symmetrical to the weakening line 25.

Die Tube wird wie folgt hergestellt:
Ein wie in Fig. 1 gezeigter Zuschnitt wird um die Verbindungslinien zwischen den Seitenwänden und dem Klebestreifen 11 zu einer Hülse gefaltet und geschlossen, indem der Klebestreifen 11 an die zweite Seitenwand 6 an deren freien Seitenkante angeklebt wird. Über einen Dorn wird ein Folienbeutel gestülpt. Über diesen wird die Schachtelhülse gestülpt. Darauf wird zuerst die zweite Abdeckplatte 16 um im wesentlichen 90 Grad umgefaltet und dann wird die erste Abdeckplatte 12 um im wesentlichen 90 Grad umgefaltet und mit der zweiten Abdeckplatte 16 verklebt. Daraufhin werden in dieser Reihenfolge die Klebelasche 13, die Klebelasche 14 und die Klebelasche 15 um im wesentlichen 90 Grad umgefaltet und mit der zweiten Seitenwand 6, der dritten Seitenwand 7 bzw. der vierten Seitenwand 8 verklebt.The tube is made as follows:
A blank as shown in FIG. 1 is folded and closed around the connecting lines between the side walls and the adhesive strip 11 to form a sleeve by the adhesive strip 11 being glued to the second side wall 6 at its free side edge. A foil bag is put over a mandrel. The box sleeve is placed over this. Thereupon the second cover plate 16 is first folded over by essentially 90 degrees and then the first cover plate 12 is folded over by essentially 90 degrees and glued to the second cover plate 16. The adhesive flap 13, the adhesive flap 14 and the adhesive flap 15 are then folded over in this order by essentially 90 degrees and with the second side wall 6, the third side wall 7 or the fourth side wall 8 glued.

Durch den Dorn wird ein Stanzwerkzeug geführt, mit dem ein Loch durch die Beutelfolie und die Abdeckplatten 12 und 16 gestanzt wird. Ein wie in Figur 2 gezeigter Ausgießstutzen 32 wird von außen in dieses Loch eingesetzt und innen mittels eines Formstempels umgeformt und fest mit dem Beutel und der Faltschachtel verbunden. Die so vorbereitete Tube wird von dem Dorn gezogen und zur Befüllung durch den noch offenen Boden, der die Rückseite bildet, gegeben.A punching tool is guided through the mandrel, with which a hole is punched through the bag film and the cover plates 12 and 16. A pouring spout 32, as shown in FIG. 2, is inserted into this hole from the outside and is reshaped on the inside by means of a shaping stamp and firmly connected to the bag and the folding box. The tube prepared in this way is pulled from the mandrel and passed through the still open bottom, which forms the back, for filling.

Der Bodenverschluß beginnt mit dem Spreizen und Siegeln der überstehenden Beutelfolie des Innenbeutels. Die dabei entstehenden Folienzipfel werden um etwa 180 Grad nach innen gefaltet. Die Rückwand 9 wird nach innen gefaltet und mit der Klebelasche 10 so verklebt, daß die Rückwand 9 entlang der Knicklinie 17 eine Wölbung von etwa 10 Grad nach innen aufweist. Das ist besonders geeignet durchführbar, da die Höhe der Rückwand 9 etwas größer ist als die Breite der Seitenwände 7 bzw. 8.The bottom closure begins with the spreading and sealing of the protruding bag film of the inner bag. The resulting film tips are folded inwards by about 180 degrees. The rear wall 9 is folded inwards and glued to the adhesive flap 10 such that the rear wall 9 has a curvature of approximately 10 degrees inwards along the fold line 17. This can be carried out particularly suitably, since the height of the rear wall 9 is somewhat larger than the width of the side walls 7 and 8.

Die Benutzung der Tube geschieht auf die folgende Weise:
Nachdem die gefüllte Tube in den Verkehr gebracht ist, entfernt der Verbraucher einen auf dem Ausgießstutzen vorgesehenen Verschluß und drückt die Tubenverpackung von der Hinterseite her an den beiden Seitenwänden 5 und 6 zusammen. Daraufhin wölbt sich die Rückwand 9 in den Karton hinein. Der Innenbeutel bleibt daher immer gesichert in dem Karton. Durch das Zusammendrücken der ersten und zweiten Wand 5 und 6 werden die dritte und vierte Seitenwand 7 und 8 entlang der Schwächungslinien 22 und 23 nach außen geknickt. Der Übergang zu der Vorderwand, die durch die erste und zweite Abdeckplatte 12 und 16 gebildet wird, geschieht entlang der Schwächungslinien 24 und 25 bzw. entlang der Knicklinien 30 und 31. So läßt sich die Tube ganz zusammendrücken, bis die beiden Seitenwände 5 und 6 parallel aneinander liegen, nur noch durch den entleerten Innenbeutel getrennt.The tube is used in the following way:
After the filled tube is placed on the market, the consumer removes a closure provided on the pouring spout and presses the tube packaging together from the rear on the two side walls 5 and 6. Then the rear wall 9 bulges into the carton. The inner bag therefore always remains secured in the box. By compressing the first and second walls 5 and 6, the third and fourth side walls 7 and 8 are bent outwards along the weakening lines 22 and 23. The transition to the front wall, which is formed by the first and second cover plates 12 and 16, takes place along the weakening lines 24 and 25 or along the kink lines 30 and 31. Thus, the tube can be compressed completely until the two Side walls 5 and 6 lie parallel to each other, only separated by the empty inner bag.

Wenn die Tube ganz geleert ist, reißt der Verbraucher den Karton auf. In Fig. 3 ist ein Zwischenstadium des Aufreißens gezeigt, bei dem die beiden Deckplatten 12 und 16 geöffnet sind. Weiterhin kann der Karton an den Schwächungslinien 22, 23; 24, 25; 26, 27; 28, 29 aufgetrennt werden und der Innenbeutel kann leicht entnommen werden. Es stehen dann der aus einem gut wiederverwertbaren Material bestehende Karton und ein leichter Innenbeutel zur Verfügung, die beide gut entsorgt werden können.When the tube is completely empty, the consumer tears open the box. In Fig. 3, an intermediate stage of tearing is shown, in which the two cover plates 12 and 16 are open. Furthermore, the carton on the weakening lines 22, 23; 24, 25; 26, 27; 28, 29 are separated and the inner bag can be easily removed. The cardboard box made of a highly recyclable material and a light inner bag are then available, both of which can be disposed of easily.

Bei der obigen Ausführungsform sind sowohl die Rückwand (9) als auch die Deckplatten 12 und 16 in rechteckiger Form ausgebildet. Diese Elemente können jedoch auch in dreieckiger Form ausgebildet sein. Dann sind zwei der drei Seitenwände mit der Rückwand verbunden, während die dritte Seitenwand nicht mit der Rückwand verbunden ist. Beim Zusammendrücken der beiden mit der Rückwand verbundenen Seitenwände wird die dritte Seitenwand nach außen geknickt.In the above embodiment, both the rear wall (9) and the cover plates 12 and 16 are formed in a rectangular shape. However, these elements can also be designed in a triangular shape. Then two of the three side walls are connected to the rear wall, while the third side wall is not connected to the rear wall. When the two side walls connected to the rear wall are pressed together, the third side wall is bent outwards.

Ebenfalls ist eine sechseckige Ausbildung der Rückwand und der beiden Abdeckplatten gut ausführbar. Wieder sind zwei einander gegenüberliegende Seitenwände mit der Rückwand verbunden. Die anderen vier Seitenwände sind nicht mit der Rückwand verbunden. Beim Zusammendrücken der beiden mit der Rückwand verbundenen Seitenwände stülpen sich die anderen vier Seitenwände automatisch nach außen. Es bedarf nicht einmal der Schwächungslinien 22 und 23 bei der eingangs erwähnten Ausführungsform.A hexagonal design of the rear wall and the two cover plates can also be carried out well. Again, two opposite side walls are connected to the rear wall. The other four side walls are not connected to the rear wall. When the two side walls connected to the rear wall are pressed together, the other four side walls automatically turn outwards. It does not even require the weakening lines 22 and 23 in the embodiment mentioned at the beginning.
