Abstract

A packaging system for bulk goods or material comprises a hollow polygonal blown plastic form or container for accommodating the material which is to be contained therein. A cardboard cover surrounds and is fixed to the hollow plastic form. The hollow plastic form has at least one outer edge indentation in a corner area, corresponding to a polygonal area of the cardboard cover which can be folded inside for locking or securement purposes, which is symmetrical to a corner fold line of the cardboard cover, and which is connected to the cardboard cover by at least one stamped line arranged perpendicular to the corner fold line and two fold lines forming a V-shape. The packaging system enables secure fastening between the hollow plastic form and the wrapper. To achieve this, the polygonal area of the cover is shaped as a square, and the V-shaped fold lines merge into two stamped lines culminating in a point. The corner shaped indentation is defined by flat surfaces adapting to this area of the cardboard cover, which may also be plastic, or other suitable material.

Description

Die Erfindung betrifft eine Verpackung für schüttfähige Güter, wie Flüssigkeiten oder rieselförmige Feingranulate, die aus einem inneren, das zu verpackende Gut aufnehmenden, blasgeformten, mehreckigen Kunststoffhohlkörper und aus einer den Kunststoffhohlkörper umgebenden manschettenförmigen Umhüllung aus Karton besteht, die am Kunststoffhohlkörper formschlüssig fixiert ist, wozu der Kunststoffhohlkörper mindestens eine außenrandseitige Einbuchtung in einem Eckbereich aufweist, der ein bei der Montage zur Arretierung nach innen einfalzbarer, mehreckiger Bereich der Umhüllung aus Karton entspricht, welcher symmetrisch zu einer Eckfaltlinie der Umhüllung angeordnet ist und über wenigstens eine im wesentlichen quer zur Eckfaltlinie angeordnete Stanzlinie und wenigstens zwei V-förmig zueinander angeordnete Faltlinien mit der Umhüllung verbunden ist.The invention relates to packaging for bulk goods, such as Liquids or granular fine granules, which are made from an inner, the to be packed well-absorbent, blow-molded, polygonal Plastic hollow body and from a surrounding the plastic hollow body sleeve-shaped wrapping made of cardboard, which on Hollow plastic body is positively fixed, including the hollow plastic body at least one indentation on the outer edge in a corner area has a foldable inward during assembly for locking, polygonal area of the wrapping made of cardboard corresponds to which is arranged symmetrically to a corner fold line of the envelope and over at least one arranged essentially transversely to the corner folding line Punching line and at least two V-shaped folding lines is connected to the wrapper.

Eine solche Verpackung der Anmelderin wird seit Jahren in großem Umfang vertrieben und hat sich in der Praxis bewährt. Diese bekannte Verpackung entspricht weitgehend derjenigen, wie eine solche in der DE 39 21 258 C2 der Anmelderin beschrieben ist. Demgegenüber ist die im Markt befindliche Verpackung derart weitergebildet, daß die wenigstens eine Einbuchtung im Kunststoffhohlkörper etwa halbtropfenförmig ausgebildet ist und daß der einfalzbare Bereich der Umhüllung aus Karton als gleichseitiges Dreieck ausgebildet ist, von dem zwei Seiten V-förmig symmetrisch zu einer Eckfaltlinie der Umhüllung angeordnet und über Faltlinien mit der Umhüllung verbunden sind, während die dritte Seite des Bereiches quer zu dieser Eckfaltlinie der Umhüllung angeordnet und über eine Stanzlinie mit der Umhüllung in Kontakt steht. Durch einfaches Eindrücken faltet sich dieser Bereich der Umhüllung dann in die entsprechende Einbuchtung des Kunststoffhohlköpers ein und legt die Umhüllung am Hohlkörper fest vgl. DE-A- 4 445 213).Such packaging by the applicant has been on a large scale for years distributed and has proven itself in practice. This well-known packaging largely corresponds to that such as that in DE 39 21 258 C2 Applicant is described. In contrast is the one in the market Packaging developed in such a way that the at least one indentation in the Hollow plastic body is approximately half-drop-shaped and that foldable area of the cardboard wrapping as an equilateral triangle is formed, from the two sides V-shaped symmetrically to a corner folding line arranged of the wrapping and connected to the wrapping via fold lines while the third side of the area is transverse to this corner folding line Wrapping arranged and in contact with the wrapping via a punching line stands. This area of the envelope then folds by simply pressing it in into the corresponding recess of the hollow plastic body and places the Wrapping firmly on the hollow body see. DE-A-4 445 213).

Wird bei der bisherigen Lösung der einfalzbare Bereich, d.h. das Dreieck, nach innen in die Einbuchtung des Kunststoffhohlkörpers eingeklappt, verlaufen die beiden Hälften der vorher waagerechten Seite des Bereiches mit einer Schräge von etwa 60° bezogen auf die senkrechte Eckkante der Ummantelung. In der Praxis hat sich nun herausgestellt, daß es vorkommen kann, daß der Kunststoffhohlkörper aus der Ummantelung herausrutscht. Dies ist darauf zurückzuführen, daß bei Belastung, d.h. bei einem Verschieben des Kunststoffhohlkörpers in der Kartonummantelung, die in der Einbuchtung anliegenden schrägen Kanten des Ummantelungsbereiches versuchen, nach außen auszuweichen, so daß ein Spiel zwischen dem Kunststoffhohlkörper und der Ummantelung entsteht, was letztendlich zum Herausrutschen des Kunststoffhohlkörpers aus der Ummantelung führen kann.If the foldable area, i.e. the triangle, after folded into the indentation of the hollow plastic body, the both halves of the previously horizontal side of the area with a slope of about 60 ° related to the vertical corner edge of the casing. In the Practice has now turned out that it can happen that the plastic hollow body slips out of the casing. This is due to, that under load, i.e. when moving the plastic hollow body in the Cardboard casing, the inclined edges of the Sheathing area try to escape to the outside, so that a Game between the plastic hollow body and the casing creates what ultimately to slide the plastic hollow body out of the casing can lead.

Demgegenüber besteht die Aufgabe der Erfindung darin, eine gattungsgemäße Verpackung so weiterzubilden, daß ohne größeren Herstellungs- und Montageaufwand eine sicherere Befestigung zwischen Kunststoffhohlkörper und Ummantelung gewährleistet ist, ohne daß die Gefahr eines Herausrutschens des Kunststoffhohlkörpers aus der Kunststoffummantelung besteht.In contrast, the object of the invention is a generic Develop packaging so that without major manufacturing and Assembly effort one ensures secure attachment between the hollow plastic body and the casing is without the risk of the Plastic hollow body consists of the plastic jacket.

Diese Aufgabe wird mit einer Verpackung der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, daß der mehreckige Bereich der Umhüllung viereckig ausgebildet ist, wobei die V-förmigen Faltlinien in zwei spitz zulaufende Stanzlinienteile übergehen und wobei die eckenförmige Einbuchtung in Anpassung an diesen Bereich der Ummantelung von ebenen Flächen begrenzt ist.This task is accomplished with packaging of the type described in the introduction solved according to the invention in that the polygonal region of the envelope is square, the V-shaped fold lines in two tapering Die cut line parts and the corner-shaped indentation in adjustment is limited to this area of the sheathing of flat surfaces.

Gegenüber der bekannten Verpackung, bei der der eingefalzte Bereich der Umhüllung nur punktförmig in der dort tropfenförmigen Einbuchtung anliegt, wird durch die erfindungsgemäße Weiterbildung erreicht, daß der eingefaltete Bereich der Ummantelung in der würfeleckenförmigen Einbuchtung linien- bzw. flächenförmig anliegt, so daß die komplette offene Eindrückkante des Ummantelungsbereiches auf der Fläche der Vertiefung der Hohlkörpereinbuchtung anliegt. Die spitz zulaufenden Stanzlinienbereiche befinden sich dabei in eingefalteter Lage in etwa in einer waagerechten Linie und liegen exakt an der entsprechenden ebenen Fläche der Einbuchtung an, so daß die somit linienförmige formschlüssige Verbindung wesentlich größere Druckkräfte aufnehmen kann. Damit ist eine sichere Arretierung zwischen Kunststoffhohlkörper und Ummantelung gewährleistet. Der Herstellungs- und Montageaufwand der Verpackung wird dadurch nicht vergrößert, da lediglich die Einbuchtung beim Blasformprozeß anders ausgeformt und die Stanzung des Kartonzuschnitts geringfügig modifiziert werden muß.Compared to the known packaging, in which the folded area of the Envelope is only punctiform in the drop-shaped indentation there achieved by the further development of the invention that the folded area the sheathing in the cube-corner-shaped recess line or lies flat, so that the complete open edge of the Sheathing area on the surface of the recess of the hollow indentation is present. The tapered punch line areas are there in the folded position about a horizontal line and lie exactly on the corresponding level Surface of the indentation, so that the linear form-fitting Connection can absorb much greater pressure forces. So that's one secure locking between the hollow plastic body and the casing is guaranteed. The manufacturing and assembly costs of the packaging will not enlarged because only the indentation in the blow molding process shaped differently and the punching of the cardboard blank slightly must be modified.

In weiterer vorteilhafter Ausgestaltung ist vorgesehen, daß wenigstens zwei eckenförmige Einbuchtungen mit unterschiedlicher Ausrichtung vorgesehen sind, wobei dann selbstverständlich auch die Ummantelung zwei einfalzbare Bereiche aufweist. Durch diese Gestaltung läßt sich eine noch sicherere Arretierung von Kunststoffhohlkörper und Stützmantel gewährleisten.In a further advantageous embodiment it is provided that at least two corner-shaped indentations with different orientations are provided, then of course the casing also has two foldable areas having. This design allows an even more secure locking of Ensure hollow plastic body and support jacket.

Dabei ist besonders bevorzugt vorgesehen, daß die eckenförmigen Einbuchtungen jeweils in Richtung zum oberen bzw. unteren Hohlkörperende hin eingebuchtet ausgerichtet sind.It is particularly preferably provided that the corner-shaped Indentations in each case towards the upper or lower hollow body end indented are aligned.

Die allgemein mit 1 bezeichnete Verpackung besteht im dargestellten Beispiel aus einem querschnittlich im wesentlichen quadratischen Kunststoffhohlkörper 2 und einer manschettenartigen Ummantelung 3 aus Karton, die den Kunststoffhohlkörper 2 formschlüssig umgibt. Der Kunststoffhohlkörper 2 ist beim dargestellten Ausführungsbeispiel mit einer oberen Auflageschulter 4 ausgerüstet, an welcher der obere Rand 3a der Ummantelung anliegt. Diese Anlage des oberen Randes 3a an einer oberen Auflageschulter 4 des Kunststoffhohlkörpers 2 ist für die Erfindung jedoch nicht wesentlich, die Auflageschulter 4 kann auch entfallen. Der blasgeformte Kunststoffhohlkörper 2 weist oberseitig eine Produktentnahmeöffnung auf, welche mit einem Verschluß 5 verschließbar ist.The packaging generally designated 1 consists in the shown Example from a cross-section essentially square Plastic hollow body 2 and a sleeve-like casing 3 Cardboard that surrounds the hollow plastic body 2 in a form-fitting manner. The plastic hollow body 2 is in the illustrated embodiment with an upper Support shoulder 4 equipped, on which the upper edge 3a of the casing is present. This abutment of the upper edge 3a on an upper support shoulder 4 of the hollow plastic body 2 is not essential for the invention, however Support shoulder 4 can also be omitted. The blow molded plastic hollow body 2 has on the top a product removal opening, which with a closure 5 is lockable.

Der Kunststoffhohlkörper 2 weist in einem Eckbereich über seiner Höhe vorzugsweise zwei Einbuchtungen 6, 7 auf, deren exakte Gestaltung nachfolgend noch näher beschrieben wird. In diese Einbuchtungen 6, 7 ist jeweils ein bei der Montage zur Arretierung nach innen einfalzbarer mehreckiger Bereich 8,9 der Umhüllung 3 einfaltbar. Diese Bereiche 8,9 werden nachfolgend ebenfalls noch näher beschrieben.The plastic hollow body 2 has in a corner area above its height preferably two indentations 6, 7, the exact design will be described in more detail below. In these indentations 6, 7 is a polygonal one that can be folded inwards during assembly for locking purposes Area 8.9 of the wrapping 3 foldable. These areas 8,9 are as follows also described in more detail.

Wie aus den Figuren 2a bis 2c hervorgeht, in denen die Figur 2b einen Schnitt gemäß der Linie A-B in Figur 2a und die Figur 2c einen Schnitt gemäß der Linie C-D in Figur 2a darstellt, ist die Einbuchtung 6 des Kunststoffhohlkörpers 2 halbtropfenförmig ausgebildet. Dies geht am besten aus der Figur 2c hervor. Der zugehörige einfalzbare Bereich 8 der Umhüllung 3 bei einer Verpackung nach dem Stand der Technik ist in den Figuren 4a und 4b dargestellt. Dieser einfalzbare Bereich 8 ist beim Stand der Technik in der Form eines gleichseitigen Dreiecks gestaltet, welches symmetrisch zu einer Eckfaltlinie 10 der Umhüllung angeordnet ist, nämlich derart, daß der Bereich 8 über zwei V-förmig zueinander angeordnete Faltlinien 11a und 11b mit dem sonstigen Bereich der Umhüllung 3 verbunden ist, während die Enden der Faltlinien 11a und 11b in eine Stanzlinie 11c übergehen, die quer zur Eckfaltlinie 10 angeordnet ist.As can be seen from FIGS. 2a to 2c, in which FIG. 2b shows a section along the line A-B in Figure 2a and Figure 2c a section along the line C-D in FIG. 2a is the indentation 6 of the hollow plastic body 2 semi-drop-shaped. This is best seen in Figure 2c. The associated foldable region 8 of the wrapping 3 in the case of packaging according to the prior art is shown in Figures 4a and 4b. This foldable area 8 is in the prior art in the form of an equilateral Triangular, which is symmetrical to a corner fold line 10 of the envelope is arranged, namely in such a way that the area 8 over two V-shaped to each other arranged fold lines 11a and 11b with the other area of the wrapper 3 is connected while the ends of the folding lines 11a and 11b into a punching line 11c, which is arranged transversely to the corner folding line 10.

Bei einer derart gestalteten Verpackung nach dem Stand der Technik wird nach dem Einschieben des Kunststoffhohlkörpers 2 in die Ummantelung 3 bei der Montage der Verpackung 1 anschließend der Bereich 8 der Umhüllung nach innen in die Einbuchtung 6 eingedrückt bzw. eingeschwenkt, was dazu führt, daß der Bereich 8 in der in den Figuren 2a bis 2c gezeigten Weise in der Einbuchtung 6 anliegt. Erkennbar berührt der Bereich 8 der Umhüllung 3 die tropfenförmige Einbuchtung 6 nur in zwei Randpunkten, die mit 12 bezeichnet sind. Demgegenüber unterscheidet sich die erfindungsgemäße Verpackung durch die Gestaltung der Bereiche 8 bzw. 9 der Umhüllung 2 und der Einbuchtungen 6 bzw. 7 des Kunststoffhohlkörpers 2, wie dies aus den Figuren 3a bis 3c und 5a bis 5b hervorgeht.In the case of a packaging of this type designed according to the prior art, the insertion of the hollow plastic body 2 into the casing 3 at the Assembly of the packaging 1 then the area 8 of the wrapping pressed or swung into the indentation 6 inside, which leads to the fact that the region 8 in the indentation in the manner shown in FIGS. 2a to 2c 6 is present. The area 8 of the casing 3 can be seen touching the drop-shaped one Indentation 6 only in two boundary points, which are designated by 12. In contrast, the packaging according to the invention differs in that Design of areas 8 and 9 of casing 2 and indentations 6 and 7 of the plastic hollow body 2, as shown in Figures 3a to 3c and 5a to 5b.

Wie am besten aus Figur 3c zu erkennen ist, welche einen Schnitt gemäß der Linie G-H in Figur 3a darstellt, während die Figur 3b einen Schnitt gemäß der Linie E-F in Figur 3a darstellt, ist die Einbuchtung 6 bzw. 7 der erfindungsgemäßen Verpackung würfeleckenförmig mit ebenen Wandflächen 6a ausgebildet, derart, daß der einfalzbare Bereich 8 der Umhüllung 3 weitgehend vollflächig in diese Einbuchtung 6 eingreifbar ist.As can best be seen from FIG. 3c, which shows a section according to FIG Line G-H in Figure 3a, while Figure 3b shows a section according to the Line E-F in Figure 3a, the indentation 6 and 7 of the invention Packaging in the shape of a cube corner with flat wall surfaces 6a formed such that the foldable area 8 of the casing 3 largely can be fully engaged in this indentation 6.

Dazu ist der jeweilige Bereich 8 bzw. 9 der Umhüllung 3 viereckig gestaltet, wie am besten aus den Figuren 5a und 5b hervorgeht. Die symmetrisch zur Eckfaltlinie 10 angeordneten V-förmig zueinander verlaufenden Faltlinien 11a, 11b gehen nämlich, anders als beim Stand der Technik, nicht in eine einzige Stanzlinie über, sondern in zwei spitz zulaufende Stanzlinienteile 11d, 11e, welche in eingefalteter Lage (Figur 5b) gemeinsam eine im wesentlichen ebene Kante bilden, die weitgehend linienförmig an der zugeordneten Wandung 6a der Einbuchtung 6 anliegt, was durch das Bezugszeichen 13 in Figur 3c angedeutet ist.For this purpose, the respective area 8 or 9 of the casing 3 is designed as a square, such as best shown in Figures 5a and 5b. The symmetrical to Corner folding line 10 arranged V-shaped folding lines 11a, 11b, in contrast to the prior art, does not go into one Punching line over, but in two tapered punching line parts 11d, 11e, which in folded position (Figure 5b) together a substantially flat edge form that largely linearly on the associated wall 6a Indentation 6 abuts, which is indicated by the reference numeral 13 in Figure 3c is.

Erkennbar ergibt sich somit bei der erfindungsgemäßen Verpackung eine Ausgestaltung, bei der die jeweilige Einbuchtung 6 bzw. 7 des Kunststoffhohlkörpers 2 genau der Form des zugeordneten Bereichs 8 bzw. 9 der Umhüllung 3 angepaßt ist, wodurch insbesondere die jeweilige freie Kante (Stanzlinien 11d bzw. 11e) des Bereiches 8 bzw. 9 der Umhüllung 2 linienförmig an der zugeordneten Fläche 6a der Einbuchtung 6 bzw. 7 anliegen. Durch die formbündige Anlage ist eine exakte Fixierung der Ummantelung 3 am Kunststoffhohlkörper 2 gewährleistet. This can be seen in the packaging according to the invention Design in which the respective indentation 6 or 7 of the Plastic hollow body 2 exactly the shape of the assigned area 8 or 9 is adapted to the envelope 3, whereby in particular the respective free edge (Stamped lines 11d and 11e) of the area 8 and 9 of the casing 2 in a line rest against the assigned surface 6a of the indentation 6 or 7. Through the form-fitting system is an exact fixation of the casing 3 am Plastic hollow body 2 guaranteed.

Wie aus Figur 1 hervorgeht, sind zur weiteren Verbesserung der Arretierung von Stützmantel 3 und Hohlkörper 2 über der Höhe 2 Einbuchtungen 6 bzw. 7 mit entsprechenden Bereichen 8, 9 der Ummantelung 3 vorgesehen. Die Einbuchtungen 6 und 7 und die Bereiche 8 und 9 sind dabei jeweils identisch aufgebaut, vorzugsweise ist die Ausrichtung jedoch entgegengesetzt, um die Arretierwirkung zu erhöhen. Dabei ist besonders bevorzugt vorgesehen, daß die eckenförmigen Einbuchtungen 6 bzw. 7 jeweils in Richtung zum oberen bzw. unteren Hohlkörperende hin eingebuchtet ausgerichtet sind.As can be seen from FIG. 1, the Locking of support jacket 3 and hollow body 2 above the height 2 indentations 6 and 7 provided with corresponding areas 8, 9 of the casing 3. The indentations 6 and 7 and the areas 8 and 9 are each identical built up, but preferably the orientation is opposite to the Increase locking effect. It is particularly preferably provided that the corner-shaped indentations 6 and 7 in the direction of the upper and lower hollow body end are aligned indented.

Natürlich ist die Erfindung nicht auf die dargestellten Ausführungsbeispiele beschränkt. Weitere Ausgestaltungen sind möglich, ohne den Bereich der Ansprüche zu verlassen. So kann die obere Auflageschulter 4 des Hohlkörpers 2 ohne weiteres entfallen, wenn zwei entgegengesetzt angeordnete Einbuchtungen 6, 7 vorgesehen sind und dergl. mehr.Of course, the invention is not limited to the illustrated embodiments limited. Further configurations are possible without the scope of the claims leave. So the upper support shoulder 4 of the hollow body 2 can easily omitted if two oppositely arranged indentations 6, 7 are provided and the like. More.
