Abstract

Pack made from a single-piece board blank, to the inside of which a sealable coating is applied. An edge strip, which extends approximately across half of the two side panels and an adjacent end panel of the pack and the transition of which from the free half of the side panel is at least approximately right-angled, is provided at the top free edge of the pack above a sealed seam.

Description

Die Erfindung bezieht sich auf eine Verpackung aus einem einteiligen Zuschnitt aus Karton od.dgl. wie im oberbegritt des Anspruchs 1 beschrieben.The invention relates to packaging made from a one-piece blank of cardboard or the like. as described in the preamble of claim 1.

Derartige Verpackungen (siehe Z.B. US-A-4.362.245) sind in ihrer Anwendung sehr vorteilhaft und eignen sich besonders als Flüssigkeitsverpackungen, wobei sie auch bei einer großen Füllmenge noch ausreichend Festigkeitseigenschaften aufweisen.Such packagings (see, for example, US-A-4,362,245) are very advantageous in their use and are particularly suitable as liquid packagings, although they still have sufficient strength properties even with a large filling quantity.

Daraus resultiert aber, daß sie nur sehr schwer zu öffnen sind.However, this means that they are very difficult to open.

Der Erfindung liegt die Aufgabe zugrunde, eine Verpackung der genannten Art so auszugestalten, daß sie auch ohne Zuhilfenahme von Werkzeugen leicht zu öffnen und zu entleeren ist.The invention has for its object to design a packaging of the type mentioned so that it is easy to open and empty without the aid of tools.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale im Kenntlichen des Anspruchs 1 gelöst.This object is achieved by the features in the characterizing part of claim 1.

Dadurch läßt sich die Verpackung am Randstreifen erfassen und mit dessen Hilfe aufreißen.In this way, the packaging can be grasped at the edge strip and torn open with its help.

Außerdem ist eine wirklich flachliegende obere Kopfpartie der Verpackung gewährleistet, die sich dann auch leicht öffnen läßt.In addition, a really flat top part of the packaging is guaranteed, which can then be easily opened.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß am Übergang von der freien Seitenwand-Hälfte zum Randstreifen eine Einkerbung vorgesehen ist.It is also very advantageous if, according to the invention, a notch is provided at the transition from the free side wall half to the edge strip.

Damit wird das Aufreißen noch weiter erleichtert.This makes tearing open even easier.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, daß die Siegelnaht am oberen Ende der Verpackung stufenförmig und parallel zur Außenkante verläuft.A further advantageous embodiment of the invention is that the sealing seam at the upper end of the packaging is step-like and parallel to the outer edge.

Damit wird dann beim Aufreißen der Verpackung auch gleichzeitig die Siegelnaht mit aufgerissen.This means that when the packaging is torn open, the sealing seam is also torn open at the same time.

Dieses gleichzeitige Aufreißen der Siegelnaht wird auf jeden Fall gewährleistet, wenn erfindungsgemäß die Siegelnaht im Randstreifen oberhalb einer gedachten Verlängerungslinie der oberen Kante der freien Seitenwand verläuft.This simultaneous tearing of the sealing seam is guaranteed in any case if, according to the invention, the sealing seam in the edge strip runs above an imaginary extension line of the upper edge of the free side wall.

Mit 1 ist in den Fig.1 und 2 eine Verpackung bezeichnet, die aus einem einteiligen Zuschnitt aus Karton aufgerichtet ist. Dieser Karton-Zuschnitt ist sowohl auf seiner Innenseite als auch auf seiner Außenseite siegelfähig mit Kunststoff beschichtet. Die Verpackung weist zwei Seitenwände 2 und 3 sowie zwei schmälere Stirnwände 4 und 5 und einen Bodenabschnitt 6 auf. Die aus zwei Abschnitten bestehende Seitenwand 2 ist durch eine Längssiegelnaht 7 verschlossen, wobei diese Siegelnaht 7 auch über den ebenfalls aus zwei Teilen bestehenden Bodenabschnitt 6 verläuft und damit eine oben und unten offene Hülse der Verpackung bildet, die wieder flachgelegt werden kann, wie dies in Fig.3 dargestellt ist. Dabei wird die Hülse über jeweils zwei von vier zwischen den Seitenwänden 2,3 einerseits und den Stirnwänden 4,5 andererseits verlaufenden Faltlinien 8,9,10,11 zusammengelegt. Der Bodenabschnitt 6 ist von der jeweiligen Seitenwand 2,3 durch eine bogenförmig verlaufende Faltlinie 12 bzw. 13 abgeteilt, deren Enden durch eine am unteren Ende der Stirnwände 4,5 quer über diese verlaufende, gerade Faltlinie 14,15 verbunden sind. Die durch diese Faltlinien 14,15 abgeteilten Abschnitte sind durch zwei weitere Faltlinien 16,17 zu Zwickelecken unterteilt.1 in FIGS. 1 and 2 denotes a packaging which is erected from a one-piece blank of cardboard. This cardboard blank is sealably coated on its inside as well as on its outside with plastic. The packaging has two side walls 2 and 3 and two narrower end walls 4 and 5 and a bottom section 6. The side wall 2, which consists of two sections, is closed by a longitudinal sealing seam 7, this sealing seam 7 also extending over the bottom section 6, which also consists of two parts, and thus forms a sleeve of the packaging which is open at the top and bottom and which can be laid again, as shown in FIG Fig.3 is shown. The sleeve is folded over two of four fold lines 8, 9, 10, 11 running between the side walls 2, 3 on the one hand and the end walls 4, 5 on the other hand. The bottom section 6 is divided from the respective side wall 2, 3 by an arcuate folding line 12 or 13, the ends of which are straight through a running at the lower end of the end walls 4, 5 Fold line 14.15 are connected. The sections divided by these fold lines 14, 15 are divided into two corners by two further fold lines 16, 17.

Zum Aufrichten der Verpackung wird zuerst die Hülse wieder in eine im Querschnitt rechteckige Form gebracht, die dann an ihrem unteren Ende durch eine Quersiegelnaht verschlossen wird. Diese Quersiegelnaht wird dann bis zur Anlage an dem Bodenabschnitt umgelegt und gleichzeitig der Boden leicht nach Innen eingedrückt. Dadurch stehen die durch die Faltlinien 14,15,16,17 gebildeten Zwickelecken etwa senkrecht vom Boden ab und werden in einem weiteren Arbeitsgang an diesen angelegt. Die Verpackung kann nun an ihrer Oberseite befüllt werden. Anschließend wird auch hier eine Quersiegelnaht 18 angebracht, die den strichpunktiert angedeuteten Verlauf aufweist.To erect the packaging, the sleeve is first brought back into a rectangular cross-sectional shape, which is then closed at its lower end by a transverse sealing seam. This transverse sealing seam is then folded over until it rests on the base section and at the same time the base is pressed in slightly. As a result, the gusset corners formed by the fold lines 14, 15, 16, 17 protrude approximately perpendicularly from the floor and are applied to the latter in a further working step. The top of the packaging can now be filled. A transverse sealing seam 18 is then also applied here, which has the course indicated by dash-dotted lines.

Diese Siegelnaht 18 verläuft über jeweils eine Hälfte der beiden Seitenwände 2,3, über die zusammengefaltete Stirnwand 5 sowie über einen an die andere Hälfte der beiden Seitenwände sowie die andere Stirnwand angeformten Randstreifen 19 und ist Z-förmig ausgebildet. Am Beginn des Randstreifens 19 ist am Übergang zwischen diesem und der freien Seitenwand-Hälfte eine Einkerbung 20 angebracht.This sealing seam 18 runs over one half of each of the two side walls 2, 3, over the folded end wall 5 and over an edge strip 19 molded onto the other half of the two side walls and the other end wall, and is Z-shaped. At the beginning of the edge strip 19, a notch 20 is made at the transition between this and the free side wall half.

Zum Öffnen der Verpackung wird an der Einkerbung 20 eingerissen und der randstreifen 19 etwa entlang einer linie 21 abgerissen. dadurch ist die Siegelnaht 18 im Bereich des Randstreifens entfernt und die Verpackung in diesem Bereich geöffnet. Eine schräg verlaufende Faltlinie 22 dient dann dazu, daß sich eine Ausgießtülle ausbilden kann, die das Ausschütten des Füllgutes wesentlich erleichtert.To open the packaging, the notch 20 is torn and the edge strip 19 torn off approximately along a line 21. this removes the sealing seam 18 in the area of the edge strip and opens the packaging in this area. An inclined fold line 22 then serves to allow a pouring spout to form, which considerably facilitates the pouring out of the filling material.
