Abstract

Package made from a one-piece cardboard blank (1), which is coated sealably on its inner side with plastic, has an at least approximately elliptical bottom section (2) and two side walls (5, 6) articulated thereon, which in turn carry sealing edge-strips (19, 20, 21, 22) which are divided off by means of fold lines (17, 18), and also with fold lines (7, 8 or 25, 26, 27, 28) for the dividing off of gusset areas (9, 10) from the bottom section or the side walls. The fold lines, which subdivide the bottom section, continue also in the side walls and there divide off end walls (13, 14, 15, 16); additionally, on the sealing edge-strips, extension tabs (23, 24) are formed, which make possible the laying of the sealing edge-strips on the end walls. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Verpackung aus einem einteiligen Zuschnitt aus Karton od.dgl., der auf seiner inneren, dem Füllgut zugekehrten Seite siegelfähig mit Kunststoff beschichtet ist, mit einem wenigstens annähernd elliptischen Bodenabschnitt, sowie zwei daran angelenkten Seitenwänden, die ihrerseits durch Faltlinien abgeteilte Siegelrandstreifen tragen, sowie mit Faltlinien zum Abteilen von drei Zwickelflächen vom Bodenabschnitt bzw. den beiden Seitenwänden auf jeder Schmalseite der Verpackung.The invention relates to a package made of a one-piece blank of cardboard or the like, which is coated on its inner side facing the filling material with plastic, with an at least approximately elliptical bottom portion, and two hinged side walls, which in turn by folding lines wear separated sealing edge strips, as well as with folding lines for dividing three gusset areas from the bottom section or the two side walls on each narrow side of the packaging.

Aus der DE-A-24 32 935 ist bereits eine derartige Verpackung bekannt, bei der die Zwickelflächen vor dem Versiegeln der Siegelrandstreifen nach innen eingefaltet werden. Dadurch ergibt sich zwar eine verhältnismäßig gute Standfestigkeit; die Verpackung ist auch unter normalen Gebrauchsbedingungen dicht, doch hält sie größeren Belastungen nicht stand.Such a packaging is already known from DE-A-24 32 935, in which the gusset surfaces are folded inwards before the sealing edge strips are sealed. This results in a relatively good stability; the packaging is sealed even under normal conditions of use, but does not withstand major loads.

Der Erfindung liegt die Aufgabe zugrunde, eine Verpackung der eingangs genannten Art zu schaffen, die auch bei erhöhten Anforderungen noch dicht ist.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in Verlängerung der den Bodenabschnitt unterteilenden Faltlinien weitere Faltlinien über die beiden Seitenwände verlaufen, die von den Seitenwänden Stirnwände abteilen, und daß an den Siegelrandstreifen einer Seitenwand Verlängerungslappen angeformt sind, mit deren Hilfe die Siegelrandstreifen beim Aufrichten der Verpackung an die Stirnwände angelegt werden.The invention has for its object to provide a packaging of the type mentioned, which is still tight even with increased requirements.
This object is achieved in that in the extension of the fold lines dividing the bottom section further fold lines over the two side walls run, which divide end walls from the side walls, and that extension tabs are formed on the sealing edge strips of a side wall, with the aid of which the sealing edge strips are applied to the end walls when the packaging is erected.

Durch diese Ausgestaltung liegt eine im Querschnitt im wesentlichen rechteckige Verpackung vor, bei der die Zwickelflächen an die Unterseite des Bodens angelegt werden können. Dadurch und durch das Anlegen der Siegelrandstreifen mit Hilfe der Verlängerungslappen an die Stirnwände wird eine hervorragende Versteifung der Verpackung erzielt, so daß sie auch bei erhöhten und schockartigen Drücken dicht bleibt.As a result of this configuration, the packaging is essentially rectangular in cross section, in which the gusset surfaces can be placed on the underside of the base. As a result of this and by applying the sealing edge strips to the end walls with the aid of the extension tabs, an excellent stiffening of the packaging is achieved, so that it remains tight even with increased and shock-like pressures.

Eine weitere Verbesserung der Verpackung wird erreicht, wenn erfindungsgemäß die Verlängerungslappen bis in den Bereich des Bodenabschnittes reichen.
Die Verlängerungslappen werden dann in diesem Bereich zusammen mit den Zwickelflächen an die Außenseite des Bodenabschnittes angelegt, so daß eine weitere Versteifung der Verpackung erreicht wird.A further improvement of the packaging is achieved if, according to the invention, the extension tabs extend into the area of the bottom section.
The extension flaps are then placed in this area together with the gusset surfaces on the outside of the bottom section, so that a further stiffening of the packaging is achieved.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Verlängerungslappen von unten bis etwa zur halben Höhe der Verpackung reichen.It is also very advantageous if, according to the invention, the extension tabs extend from below to approximately half the height of the packaging.

Dadurch ist es beispielsweise möglich, die Verpackung von einer rechteckigen Form im unteren Bereich auf die Form eines Flachbeutels im oberen Bereich übergehen zu lassen und ihn mittels einer Querschweißnaht zu verschließen.This makes it possible, for example, to have the packaging change from a rectangular shape in the lower area to the shape of a flat bag in the upper area and to close it by means of a transverse weld seam.

Dies wird noch dadurch verbessert, daß erfindungsgemäß im oberen Abschnitt der Stirnwände von den Faltlinien zwischen Seiten- und Stirnwand unten ausgehende und an der Faltlinie der Siegelrandstreifen oben endende Rillinien vorgesehen sind.This is further improved by the fact that, according to the invention, crease lines are provided in the upper section of the end walls, starting from the fold lines between the side and end walls and ending at the fold line of the sealing edge strips.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:

  • Fig. 1 eine Ansicht eines flachliegenden Kartonzuschnittes und
  • Fig. 2 ein Schaubild einer aufgerichteten und oben verschlossenen Verpackung.
The invention is illustrated in the drawing using an exemplary embodiment. Show:
  • Fig. 1 is a view of a flat cardboard blank and
  • Fig. 2 is a diagram of an erected and closed packaging.

Mit 1 ist in Fig. 1 ein Kartonzuschnitt bezeichnet, der auf einer Seite mit einem siegelbaren Kunststoff beschichtet ist. Der Kartonzuschnitt 1 weist einen Bodenabschnitt 2 auf, der eine im wesentlichen elliptische Form hat. Die gebogenen Begrenzungslinien 3,4 sind als Faltlinien ausgebildet, und über sie sind zwei Seitenwände 5 und 6 an den Bodenabschnitt 2 angelenkt. Durch jeweils eine weitere Faltlinie 7 bzw. 8 ist vom Bodenabschnitt 2 jeweils eine Zwickelfläche 9 bzw. 10 abgeteilt. In Verlängerung dieser beiden Faltlinien 7 und 8 verlaufen zwei weitere Faltlinien 11 und 12, die sich über die beiden Seitenwände 5 und 6 erstrecken und von diesen Stirnwände 13,14,15 und 16 abteilen. An diesen Stirnwänden sind über Faltlinien 17 und 18 Siegelrandstreifen 19,20 bzw. 21,22 angeformt. Die beiden der Seitenwand 6 zugeordneten Siegelrandstreifen 19 und 21 tragen Verlängerungslappen 23 bzw. 24, die von der Mitte des Bodenabschnittes 2 bis etwa zur Mitte der Seitenwand 6 reichen. Von den Stirnwänden 13, 14,15,16 ist durch eine Faltlinie 25,26,27,28 jeweils eine weitere Zwickelfläche 29,30,31,32 abgeteilt, die jeweils an den Zwickelflächen 9 bzw. 10 angrenzt. Darüber hinaus verläuft schräg über die Stirnwände je eine Rillinie 33 bis 36, die sich zwischen den Faltlinien 11 bzw. 12 und 17 bzw. 18 erstreckt.1 in Fig. 1 denotes a cardboard blank that is coated on one side with a sealable plastic. The cardboard blank 1 has a bottom section 2 which has an essentially elliptical shape. The curved boundary lines 3, 4 are designed as fold lines, and two side walls 5 and 6 are articulated to the bottom section 2 via them. A gusset surface 9 or 10 is divided off from the bottom section 2 by a respective additional folding line 7 or 8. In extension of these two fold lines 7 and 8 there are two further fold lines 11 and 12 which extend over the two side walls 5 and 6 and divide from these end walls 13, 14, 15 and 16. Sealing edge strips 19, 20 and 21, 22 are formed on these end walls via fold lines 17 and 18. The two sealing edge strips 19 and 21 assigned to the side wall 6 carry extension tabs 23 and 24, respectively, which extend from the center of the bottom section 2 to approximately the center of the side wall 6. A further gusset surface 29, 30, 31, 32 is separated from the end walls 13, 14, 15, 16 by a folding line 25, 26, 27, 28, and is adjacent to the gusset surfaces 9 and 10, respectively. In addition, a crease line 33 to 36, which extends between the fold lines 11 or 12 and 17 or 18, extends obliquely across the end walls.

Beim Aufrichten des Kartonzuschnittes zu einer in Fig. 2 dargestellten Verpackung 100 werden die Seitenwände 5 und 6 um die Faltlinien 3 und 4 nach oben gebogen, wobei sich ein Hohlboden ausbildet. Sodann werden die Stirnwände 13 bis 16 von den Seitenwänden abgebogen und die Siegelrandstreifen 19,20 bzw. 21,22 aufeinander gelegt und miteinander versiegelt. Dabei nähern sich auch die Zwickelflächen 9,29, 31 bzw. 10,30,32 und stehen nach unten ab. Daraufhin werden die Verlängerungslappen 23,24 an die Stirnwände 13,14 angelegt und dort durch Kleben festgelegt. Als letztes werden noch die Zwickelflächen an den Bodenabschnitt 2 angelegt und ebenfalls festgeklebt.
Die so hergestellte Verpackung kann nun gefüllt und an ihrem oberen Rand mittels einer quer verlaufenden Siegelnaht verschlossen werden.When the cardboard blank is erected to form a package 100 shown in FIG. 2, the side walls 5 and 6 are bent upward about the fold lines 3 and 4, a hollow floor being formed. The end walls 13 to 16 bent from the side walls and the sealing edge strips 19, 20 and 21, 22 placed on top of each other and sealed together. The gusset surfaces 9, 29, 31 and 10, 30, 32 also approach and protrude downwards. The extension tabs 23, 24 are then placed on the end walls 13, 14 and fixed there by gluing. Finally, the gusset surfaces are placed on the bottom section 2 and also glued.
The packaging produced in this way can now be filled and closed at its upper edge by means of a transverse sealing seam.
