Definitions
- the invention relates to a tearable packaging container, made from a one-piece blank made of cardboard material that is sealable on both sides, consisting of a bottom surface and hinged side wall parts, which are connected to one another by means of connecting straps and which have tabs in the area of the upper edge of the container, the connecting straps fixed on the inside of the adjacent side wall parts and separated from the side wall part to which they are articulated by a score line separating the outer coating, which enables the fixed connecting strap to be delaminated when the handle is pulled.
- a packaging container of the type described above is described in DE-DS 25 33 205. With him, the tabs on the corners of the container stick out.
- This arrangement of the tabs has several disadvantages. In particular, it was found that the delamination of the material did not occur as desired - in the connecting flap, but in the side wall part, which made the packaging unsightly and the side wall parts could not be separated from one another in such a way that they could be folded back into the state of a flat cut. This may be due to clumsy handling, inadequate correspondence between the folded edges and the Scratch lines or similar can be attributed to or occur as a result of special container shapes and the opening that results from the opening.
- the present invention has for its object to achieve an improvement of such a packaging container, through which the delamination is always achieved in the connecting tabs when the container is torn open.
- the handle straps extend upward beyond the upper container edge, that the connecting straps further have extension parts which are fixed to the handle straps, and that the inner coating of the connecting straps is weakened to facilitate the start of delamination.
- At least one incision which cuts through the coating facing the interior of the container and is directed toward an upper corner of the container, is arranged in the connecting tabs.
- one of the handle straps is extended to a hinged lid.
- the containers shown have an approximately square bottom and cross section and slightly taper towards their opening. They can be provided with a hinged lid, or can be closed by a separate lid, not shown.
- the containers consist of a mutually sealable and liquid-tight cardboard material coated with a suitable plastic. They are used, for example, for packaging ice cream or similar products that are filled in a liquid state and only solidify in the container.
- the blank consists of a base 1 and four side wall parts 2, 3, 4, 5, on the upper edges of which, which are indicated by the folding lines 22, 23, 24, 25, grip tabs 12, 3, 14, 15 are arranged.
- the connecting straps 6, 7, 8, 9 have at their upper ends extension parts 16, 17, 18, 19, the dimensions of which are so large that they can be fastened to the handle straps 13 and 15 if the connecting straps are attached to the side wall parts 3 and 5 be fixed by sealing.
- the inner coating of the connecting tabs is weakened at its upper end in such a way that the start and possibly also the initial course of the delamination is facilitated and controlled.
- the weakening is preferably carried out by perforations or incisions that at least cut through the inner coating, but can also cut through the entire material thickness of the connecting tabs.
- a short incision 31 is shown in each of the connecting tabs 6 to 9, which runs in the direction of the upper corner of the finished container standing on its bottom 1 at an angle of approximately 30 ° to the scoring lines 26, 28.
- further incisions 32 are shown, which coincide approximately with the folding line 25 in the finished container and are thus also directed towards the upper corner of the container.
- Incisions 31 and 32 expediently do not cut through the connecting tabs over their entire width, but leave at least on both edges of the connecting tabs undamaged parts of the inner coating which are only torn when the container is opened.
- the incisions 32 not only allow the start of delamination, but also allow the material between the extension parts 16, 18 and the tabs 6, 8 to stretch if the grip tab 15 has to be bent outwards, for example, to fill the container.
- a hinged cover 35 is shown.
- the container is opened and the lid 35 and the handle straps 12, 13, 14 are folded outwards (FIG. 4).
- the jacket of the cup is now torn open by a lateral pull on the lid 35 and grip tab 13 and detached from the packaged product.
- FIG. 2 shows the container blank folded back into a flat blank, the connecting flaps 6 to 9 of which were delaminated when the jacket was torn open, the material separating in or on the cardboard layer.
- the side wall parts 2 and 4 there are, for example, the inner coatings 6a, 7a, 8a, 9a of the connecting tabs, and on the side wall parts 3 and 5 the outer coatings 6b, 7b, 8b, 9b with the cardboard layer have adhered.
- the delamination of the connecting tabs 6, 7, 9 started exactly at the upper corners of the container and initially followed the course of the oblique incisions 31, so that a part 6 c of the inner coating remained on the side wall 5.
- the tensile force is conducted via the extension part 16 fixed to it into the inner coating of the connecting flap 6 and leads to an expansion of this coating exactly at the corner of the container, that is, between that on the Corner directed end of the incision 31 and the corner.
- the tear force initially increases only slowly, since the width of the delamination follows the course of the incision 31 until the connecting flap 6 is opened over its entire width.
- Through the extension parts 16, 17, 18, 19 and the preferred incisions 31 not only makes it much easier to split the container shell, but above all ensures that the delamination also occurs when everyone is torn open. four edges in the connecting tabs and not in the side panels.
- the delamination can also begin at the incisions 32, as shown in FIG. 2 for the connecting tab 8. If the transition from the extension part 18, which is fixed on the cover 35, to the connecting tab 8, for example, is greatly weakened by a relatively long incision 32, the narrow parts of the inner coating on both sides of the incision 32 can tear at the same time. In this case, however, the delamination begins over the entire width of the connecting flap 8, as a result of which an initially higher tear strength than with the preferred oblique incisions 31 may be required.

Abstract
Description
Die Erfindung bezieht sich auf einen aufreißbaren Verpackungsbehälter, hergestellt aus einem einteiligen Zuschnitt aus beidseitig siegelfähigem Kartonmaterial, bestehend aus einer Bodenfläche und an dieser angelenkten Seitenwandteilen, die mittels Verbindungslaschen miteinander verbunden sind und die im Bereich des oberen Behälterrandes Grifflaschen besitzen, wobei d.ie Verbindungslaschen auf der Innenseite der benachbarten Seitenwandteile fixiert und von dem Seitenwandteil, an dem sie angelenkt sind, durch eine die äußere Beschichtung durchtrennende Ritzlinie, die eine Delaminierung der fixierten Verbindungslasche bei Zug an der Grifflasche ermöglicht, abgeteilt sind.The invention relates to a tearable packaging container, made from a one-piece blank made of cardboard material that is sealable on both sides, consisting of a bottom surface and hinged side wall parts, which are connected to one another by means of connecting straps and which have tabs in the area of the upper edge of the container, the connecting straps fixed on the inside of the adjacent side wall parts and separated from the side wall part to which they are articulated by a score line separating the outer coating, which enables the fixed connecting strap to be delaminated when the handle is pulled.
Ein Verpackungsbehälter der vorstehend beschriebenen Art ist in DE-DS 25 33 205 beschrieben. Bei ihm stehen die Grifflaschen an den Ecken des Behälters seitlich ab. Diese Anordnung der Grifflaschen hat verschiedene Nachteile. Insbesondere stellte sich heraus, daß die Delaminierung des Materials nichtwie gewünscht - in der Verbindungslasche, sondern in dem Seitenwandteil erfolgte, wodurch die Verpackung unansehnlich wurde und die Seitenwandteile sich nicht so voneinander trennen liessen, daß sie in den Zustand eines flachen Zuschnitts zurückgefaltet werden konnten. Dies mag auf ungeschickte Handhabung, auf ungenügende Übereinstimmung der Faltkanten mit den Ritzlinien o.ä. zurückzuführen sein oder infolge besonderer Behälterformen und der durch die bedingten Öffnungsweise auftreten.A packaging container of the type described above is described in DE-DS 25 33 205. With him, the tabs on the corners of the container stick out. This arrangement of the tabs has several disadvantages. In particular, it was found that the delamination of the material did not occur as desired - in the connecting flap, but in the side wall part, which made the packaging unsightly and the side wall parts could not be separated from one another in such a way that they could be folded back into the state of a flat cut. This may be due to clumsy handling, inadequate correspondence between the folded edges and the Scratch lines or similar can be attributed to or occur as a result of special container shapes and the opening that results from the opening.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Verbesserung eines derartigen Verpackungsbehälters zu erreichen, durch welche die Delaminierung beim Aufreißen des Behälters immer in den Verbindungslaschen erzielt wird.The present invention has for its object to achieve an improvement of such a packaging container, through which the delamination is always achieved in the connecting tabs when the container is torn open.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß sich die Grifflaschen nach oben über den oberen Behälterrand hinaus erstrecken, daß weiter die Verbindungslaschen Verlängerungsteile besitzen, welche an den Grifflaschen fixiert sind, und daß die innere Beschichtung der Verbindungslaschen zur Erleichterung des Beginns einer Delaminierung geschwächt ist.This object is achieved in that the handle straps extend upward beyond the upper container edge, that the connecting straps further have extension parts which are fixed to the handle straps, and that the inner coating of the connecting straps is weakened to facilitate the start of delamination.
Hierdurch wird erreicht, daß beim Aufreißen des Verpackungsbehälters eine Trennung im Material der Verbindungslaschen erfolgt, was bedeutet, daß eine saubere und kontrollierte Delaminierung stattfindet, die sich auf die Fläche der verhältnismäßig schmalen Verbindungslaschen beschränkt.This ensures that when the packaging container is torn, there is a separation in the material of the connecting straps, which means that a clean and controlled delamination takes place, which is limited to the area of the relatively narrow connecting straps.
Sehr vorteilhaft ist es auch, wenn gemäß der Erfindung in den Verbindungslaschen wenigstens ein, die dem Behälterinneren zugewandte Beschichtung durchtrennender, auf eine obere Ecke des Behälters gerichteter Einschnitt angeordnet ist.It is also very advantageous if, according to the invention, at least one incision, which cuts through the coating facing the interior of the container and is directed toward an upper corner of the container, is arranged in the connecting tabs.
Dadurch ist gewährleistet, daß beim Ausüben von Zug auf die Grifflasche, die VerbindungslaschEnentlang der Einschnitte aufreißen und delaminieren.This ensures that when tension is exerted on the grip tab, the connecting tabs tear open and delaminate along the incisions.
Ebenfalls vorteilhaft ist es, wenn gemäß der Erfindung eine der Grifflaschen zu einem Klappdeckel verlängert ist.It is also advantageous if, according to the invention, one of the handle straps is extended to a hinged lid.
Zum einen wird dadurch eine einfache Verschlußmöglichkeit geschaffen und zum anderen das Anfassen der Grifflasche beim Aufreißen des Verpackungsbehälters erheblich erleichtert.On the one hand, this creates a simple closure option and, on the other hand, it makes it considerably easier to touch the handle when the packaging container is torn open.
In der Zeichnung ist die Erfindung anhand von zwei Ausführungsbeispielen veranschaulicht. Dabei zeigen:
- Fig. 1 die innere Seite eines flachen, ungesiegelten Zuschnitts,
- Fig. 2 die innere Seite eines aufgerissenen, wieder in einen flachen Zustand zurückgefalteten Behälter,
- Fig. 3 einen Behälter mit Klappdeckel gemäß Fig. 2,
- Fig. 4 den Beginn des Öffnens eines gefüllten Behälters und
- Fig. 5 das Aufreißen des Behälters, nachdem dieser zum Entleeren umgestülpt wurde.
- 1 shows the inner side of a flat, unsealed blank,
- 2 shows the inner side of a torn container which has been folded back into a flat state,
- 3 shows a container with a hinged lid according to FIG. 2,
- Fig. 4 shows the beginning of opening a filled container and
- Fig. 5 shows the tearing open of the container after it has been turned inside out for emptying.
Die dargestellten Behälter haben einen etwa quadratischen Boden und Querschnitt und erweitern sich leicht konisch zu ihrer Öffnung hin. Sie können mit einem angelenkten Deckel versehen sein, oder durch einen nicht gezeigten, gesonderten Deckel verschlossen werden. Die Behälter bestehen aus einem beiderseitig siegelfähig und flüssigkeitsdicht mit einem geeigneten Kunststoff beschichteten Kartonmaterial. Sie werden beispielsweise für die Verpackung von Eiskrem oder ähnlichen Produkten verwendet, die in einem flüssigen Zustand eingefüllt werden und erst in dem Behälter erstarren.The containers shown have an approximately square bottom and cross section and slightly taper towards their opening. They can be provided with a hinged lid, or can be closed by a separate lid, not shown. The containers consist of a mutually sealable and liquid-tight cardboard material coated with a suitable plastic. They are used, for example, for packaging ice cream or similar products that are filled in a liquid state and only solidify in the container.
Der Zuschnitt besteht aus einem Boden 1 und vier Seitenwandteilen 2,3,4,5, an deren oberen Kanten, die durch die Faltlinien 22,23,24,25 bezeichnet sind, Grifflaschen 12,;3,14,15 angeordnet sind. Beiderseits der Seitenwände 2 und 4 befinden sich Verbindungslaschen 6,7,8,9, die durch Schwächungslinien, insbesondere durch die äußere Beschichtung durchtrennende Ritzlinien 26,27,28,29 oder Einschnitte von den Seitenwänden abgeteilt sind. Die Verbindungslaschen 6,7,8,9 besitzen an ihren oberen Enden Verlängerungsteile 16,17,18,19, deren Abmessungen so groß sind, daß sie an den Grifflaschen 13 und 15 befestigt werden können, wenn die Verbindungslaschen an den Seitenwandteilen 3 und 5 durch Siegelung fixiert werden.The blank consists of a
Die innere Beschichtung der Verbindungslaschen ist an ihrem oberen Ende so geschwächt, daß der Beginn und gegebenenfalls auch der anfängliche Verlauf der Delaminierung erleichtert und gesteuert wird. Die Schwächung erfolgt vorzugsweise durch Perforationen oder Einschnitte, die wenigstens die innere Beschichtung durchschneiden, aber auch die ganze Materialdicke der Verbindungslaschen durchtrennen können. In Fig. 1 ist in jeder der Verbindungslaschen 6 bis 9 ein kurzer Einschnitt 31 gezeigt, der in Richtung auf die obere Ecke des fertigen, auf seinem Boden 1 stehenden Behälters etwa unter einem Winkel von 30° zu den Ritzlinien 26,28 verläuft. Zwischen den Verbindungslaschen 6 und 8 und ihren Verlängerungsteilen 16 und 18 sind weitere Einschnitte 32 dargestellt, die sich beim fertigen Behälter etwa mit der Faltlinie 25 decken und somit ebenfalls auf die obere Ecke des Behälters gerichtet sind. Einschnitte 31 und 32 durchtrennen die Verbindungslaschen zweckmäßigerweise nicht auf ihrer ganzen Breite, sondern lassen wenigstens an beiden Rändern der Verbindungslaschen Teile der inneren Beschichtung ungeschwächt, die erst beim öffnen des Behälters zerrissen werden. Die Einschnitte 32 ermöglichen nicht nur ebenfalls den Beginn des Delaminierens, sondern lassen auch eine Dehnung des Materials zwischen den Verlängerungsteilen 16,18 und den Laschen 6,8 zu, wenn die Grifflasche 15 beispielsweise zum Füllen des Behälters nach aussen gebogen werden muß.The inner coating of the connecting tabs is weakened at its upper end in such a way that the start and possibly also the initial course of the delamination is facilitated and controlled. The weakening is preferably carried out by perforations or incisions that at least cut through the inner coating, but can also cut through the entire material thickness of the connecting tabs. In Fig. 1, a
In Fig. 2 bis 5 ist anstelle der Grifflasche 15 an der FaltLinie 25 ein Klappdeckel 35 dargestellt. Zur Entleerung des [nhalts wird der Behälter geöffnet und der Deckel 35 sowie jie Grifflaschen 12,13,14 werden nach aussen umgefaltet(Fig.4). in aufrechter Stellung des Bechers, oder nachdem er auf einen Teller 36 umgestülpt wurde (Fig.5), wird nun der Mantel des Bechers durch seitlichen Zug an Deckel 35 und Grifflasche 13 aufgerissen und von dem verpackten Produkt gelöst.2 to 5, instead of the
Fig. 2 zeigt den wieder in einen flachen Zuschnitt zurückgefalteten Behälterzuschnitt, dessen Verbindungslaschen 6 bis 9 beim Aufreissen des Mantels delaminiert wurden, wobei sich das Material in oder an der Kartonschicht trennte. An den Seitenwandteilen 2 und 4 befinden sich beispielsweise noch die inneren Beschichtungen 6a,7a,8a,9a der Verbindungslaschen, und auf den Seitenwandteilen 3 und 5 sind die äusseren Beschichtungen 6b,7b,8b,9b mit der Kartonschicht haften geblieben.FIG. 2 shows the container blank folded back into a flat blank, the connecting
Bei dem dargestellten Beispiel begann die Delaminierung der Verbindungslaschen 6,7,9 genau an den oberen Behälterecken und folgte anfänglich dem Verlauf der schrägen Einschnitte 31, so daß noch ein Teil 6c der inneren Beschichtung auf der Seitenwand 5 verblieb. Bei seitlichem Zug an dem um die Faltlinie 25 abgeknickten Deckel 35 wird die Zugkraft über das an ihm fixierte Verlängerungsteil 16 in die innere Beschichtung der Verbindungslasche 6 geleitet und führt zu einer Dehnung dieser Beschichtung genau an der Ecke des Behälters, d.h., zwischen dem auf die Ecke gerichteten Ende des Einschnittes 31 und der Ecke. Durch die Konzentration der Aufreißkraft auf den Eckpunkt kann man hier die innere Beschichtung leicht zerreissen, so daß die Delaminierung beginnt. Die Weiterreißkraft nimmt zu nächst nur langsam zu, da die Breite der Delaminierung dem Verlauf des Einschnitts 31 folgt, bis die Verbindungslasche 6 auf ganzer Breite aufgetrennt wird. Durch die Verlängerungsteile 16,17,18,19 und die bevorzugten Einschnitte 31 wird nicht nur das Zerteilen des Behältermantels wesentlich erleichtert, sondern vor allem sichergestellt, daß die Delaminierung auch bei dem gleichzeitigen Aufreißen aller. vier Kanten in den Verbindungslaschen und nicht in den Seitenandteilen erfolgt.In the example shown, the delamination of the connecting
Die Delaminierung kann auch an den Einschnitten 32 beginnen, wie in Fig. 2 für die Verbindungslasche 8 gezeigt ist. Wenn der Übergang von dem Verlängerungsteil 18, das am Deckel 35 fixiert ist, zur Verbindungslasche 8 beispielsweise durch einen verhältnismäßig langen Einschnitt 32 sehr stark geschwächt ist, können die schmalen Teile der inneren Beschichtung beiderseits des Einschnitts 32 gleichzeitig zerreissen. In diesem Fall beginnt die Delaminierung allerdings auf ganzer Breite der Verbindungslasche 8, wodurch eine anfänglich höhere Reißkraft als bei den bevorzugten schrägen Einschnitten 31 erforderlich sein kann.The delamination can also begin at the
