Description

Die Erfindung betrifft einen dosenförmigen Behälter mit einem aus Karton od.dgl. gewickelten und entlang einer Längsnaht verschlossenen Mantel sowie zwei stirnseitigen Verschlußteilen, die aus Kunststoff od. dgl. bestehen, eine U-förmige Aufnahmerille für die beiden Mantelenden aufweisen und an der Innenseite des Mantels anliegen und mit diesem verschweißt sind.The invention relates to a can-shaped container with a cardboard or the like. wound and closed along a longitudinal seam jacket and two end closure parts, which are made of plastic or the like., Have a U-shaped receiving groove for the two jacket ends and rest on the inside of the jacket and are welded to it.

Derartige, z.B. aus der CH-PS 439 082 bekannte Behälter haben sich in der Praxis für vielerlei Anwendungsfälle bewährt. Sie können sehr dicht ausgebildet sein. Darüber hinaus ist aus der DE-OS 25 07 455 ein Behälter bekannt, der leicht zu öffnen ist.Beide Kriterien bei ein und demselben Behälter zu realisieren ist bisher nicht bekannt geworden und auch nur schwer durchzuführen. Aber gerade da setzt die vorliegende Erfindung ein.Such, e.g. Containers known from CH-PS 439 082 have proven themselves in practice for a variety of applications. They can be very dense. In addition, a container is known from DE-OS 25 07 455 that is easy to open. To implement both criteria in one and the same container has so far not become known and is also difficult to implement. But this is precisely where the present invention begins.

Ihr liegt die Aufgabe zugrunde, einen Behälter der eingangs genannten Art zu schaffen, der sowohl sehr dicht ist als auch leicht geöffnet werden kann.It is based on the task of creating a container of the type mentioned at the outset which is both very tight and can be opened easily.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Innenseite des Mantels ein Aufreißfaden angesiegelt ist, dessen eines Ende durch die Längsnaht hindurch aus dem Behälterinneren herausgeführt ist, daß der Mantel im Bereich des Aufreißfadens an seiner Außenseite mit zwei parallel zueinander verlaufenden Schnittlinien versehen ist, die teilweise in das Mantelmaterial eindringen, daß die beiden Schnittlinien am im Bereich der Längsnaht außenliegenden Ende des Mantels V-förmig auseinander laufen und einen Abschnitt abteilen, der als Handgriff zum Aufreißen des Behälters dient, und daß die beiden Schnittlinien im Bereich des in der Längsnaht innenliegenden Streifens des Mantels entlang der Form eines Dreiecks verlaufen, das unter dem Handgriff liegt und mit diesem versiegelt ist.This object is achieved in that a tear thread is sealed on the inside of the jacket, one end of which is led out of the interior of the container through the longitudinal seam, that the jacket is provided on the outside in the area of the tear thread with two parallel cutting lines, which partially penetrate into the jacket material, that the two cutting lines run apart in a V-shape at the outer end of the jacket in the area of the longitudinal seam and divide a section that serves as a handle for tearing open the container, and that the two cutting lines in the area of the longitudinal seam inner strip of the jacket run along the shape of a triangle, which lies under the handle and is sealed with this.

Durch die Verwendung der Kunststoff-Verschlußteile, deren Ausgestaltung und Verbindung mit dem Mantel wird einerseits eine sehr gute Dichtigkeit des Behälters erreicht, während andererseits durch den Aufreißfaden und die Art seiner Anbringung eine leichte Öffnungsmöglichkeit gegeben ist. Durch den dreieckförmigen Verlauf der Schnittlinien am innenliegenden Streifen, ist erreicht, daß beim Abziehen des Handgriffs im innenliegenden Streifen eine Materialspaltung eintritt. Der Aufreißfaden verbleibt somit zwischen dem Handgriff und der abgespalteten Schicht des innenliegenden Streifens eingesiegelt. Damit ist sichergestellt, daß der Aufreißfadem beim Erfassen des Handgriffs miterfaßt wird, wodurch ein völlig sicheres Öffnen des Behälters ermöglicht wird.Through the use of the plastic fastener parts, their design and connection with the jacket, a very good tightness of the container is achieved on the one hand, while on the other hand the tear thread and the way in which it is attached provide easy opening. The triangular shape of the cut lines on the inner strip ensures that material splitting occurs in the inner strip when the handle is pulled off. The tear thread thus remains sealed between the handle and the split layer of the inner strip. This ensures that the tear-open catch is also included when the handle is gripped, which enables a completely safe opening of the container.

Dabei ist es besonders vorteilhaft, wenn erfindungsgemäß der als Handgriff dienende Abschnitt geringfügig über die übrigen Abschnitte des Mantels vorsteht. Dadurch kann der Handgriff noch leichter erfaßt werden.It is particularly advantageous if, according to the invention, the section serving as a handle protrudes slightly beyond the remaining sections of the jacket. This makes it easier to grasp the handle.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß der Behältermantel auf seiner Innenseite mit einer siegelfähigen Schicht versehen ist. Im Bereich des Aufreißfadens und an den Mantelenden ist eine siegelfähige Beschichtung ohnehin notwendig; durch die vollflächige Schicht wird in vorteilhafter Weise eine völlige Abdichtung des Behälters erzielt.According to a further embodiment of the invention it is provided that the container jacket is provided on its inside with a sealable layer. In the area of the tear thread and at the ends of the jacket, a sealable coating is necessary anyway; the full-surface layer advantageously completely seals the container.

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

  • Fig. 1 ein Schaubild eines Behälters mit einem Mantel aus Karton sowie zwei Verschlußteilen aus Kunststoff,
  • Fig. 2 einen Längsschnitt durch den Behälter und
  • Fig. 3 eine Ansicht eines flachliegenden Kartonzuschnittes zum Herstellen des Behältermantels.
The invention is illustrated in the drawing using an exemplary embodiment. Show:
  • 1 is a diagram of a container with a jacket made of cardboard and two closure parts made of plastic,
  • Fig. 2 shows a longitudinal section through the container and
  • Fig. 3 is a view of a flat cardboard blank for producing the container shell.

In Fig. 1 ist ein im Querschnitt ovaler Behälter 1 dargestellt, dessen Mantel 2 aus einem rechteckigen Kartonzuschnitt 3(Fig.3) gewickelt und entlang einer Längsnaht 4 verschlossen ist. Der Behälter 1 weist zwei stimseitige Verschlußteile 5 auf, die identisch ausgebildet sind. Wie besonders aus Fig. 2 ersichtlich, sind diese Verschlußteile 5 topfförmig ausgebildet und ragen mit ihrem Boden in den Behälter 1 hinein. Der Rand der Verschlußteile 5 ist als U-förmige Aufnahmerille 6 für die beiden Mantelenden ausgebildet. Je nachdem, ob nur die innere Seite des Mantels oder dessen beide Seiten siegelfähig beschichtet sind, wird nur die Innenseite oder die Innen-qnd die Außenseite des Mantelendes mit dem entsprechenden Schenkel der U-förmigen Aufnahmerille 6 verschweißt. Etwa in der Mitte des Behältermantels ist an dessen Innenseite ein Aufreißfaden 7 angesiegelt der durch die Längsnaht 4 aus dem Behälter herausgeführt ist. Diesem Aufreißfaden gegenüberliegend sind an der Außenseite des Mantels 2 zwei Schnittlinien 8 und 9 vorgesehen, die parallel zueinander verlaufen und nur zum Teil in die Mantelwand eindringen. Diese beiden Schnittlinien laufen am im Bereich der Längsnaht 4 außenliegenden Ende des Mantels 2 V-förmig auseinander und teilen einen als Handgriff 10 dienenden Abschnitt ab. Dieser Handgriff 10 steht etwas über die Schnittkante des Mantels vor, so daß er zum Aufreißen des Mantels leicht erfaßt werden kann. Der Aufreißfaden 7 ist mit diesem Handgriff 10 an der Innenseite versiegelt, so daß die Aufreißkraft über den Handgriff auf den Faden übertragen wird.1 shows a cross-sectionally oval container 1, the jacket 2 of which is wound from a rectangular cardboard blank 3 (FIG. 3) and closed along a longitudinal seam 4. The container 1 has two end-side closure parts 5, which are of identical design. As can be seen particularly from FIG. 2, these closure parts 5 are cup-shaped and project into the container 1 with their base. The edge of the closure parts 5 is designed as a U-shaped receiving groove 6 for the two jacket ends. Depending on whether only the inner side of the jacket or which both sides are coated sealable, only the inside or the inner q nd the outside of the casing end to the respective leg of the U-shaped receiving groove 6 is welded. Approximately in the middle of the container shell, a tear thread 7 is sealed on the inside thereof, which is led out of the container through the longitudinal seam 4. Opposing this tear thread, two cutting lines 8 and 9 are provided on the outside of the jacket 2, which run parallel to one another and only partially penetrate into the jacket wall. These two cutting lines diverge in a V-shape at the outer end of the casing 2 in the area of the longitudinal seam 4 and divide a section serving as a handle 10. This Handle 10 protrudes slightly beyond the cut edge of the jacket so that it can be easily gripped to tear open the jacket. The tear thread 7 is sealed with this handle 10 on the inside, so that the tear force is transmitted to the thread via the handle.

Der in Fig. 3 dargestellte Zuschnitt 3 zum Herstellen des Mantels 2 hat zur Bildung der Längsnaht einen Streifen 11, der beim Wickeln des Mantels auf die Innenseite zu liegen kommt. Er ist vom übrigen Zuschnitt durch eine Prägelinie 12 abgeteilt, entlang welcher der Streifen 11 nach hinten geprägt ist, wodurch beim fertig gewickelten Mantel dieser Streifen um die Materialstärke an der Behälterinnenseite vorsteht, während die beiden einander benachbarten Endabschnitte des Mantels auf der Außenseite fluchten. Im Bereich dieses Streifens 11 verlaufen die beiden Schnittlinien 8 und 9 entlang der Form eines Dreiecks 13, welches beim fertigen Mantel unter dem Handgriff 10 liegt und mit diesem versiegelt ist. Beim Ablösen des Handgriffs wird entlang dieses Dreiecks das Zuschnittmaterial gleichzeitig gespalten.The blank 3 shown in FIG. 3 for producing the jacket 2 has a strip 11 for forming the longitudinal seam, which comes to lie on the inside when the jacket is wound. It is divided from the rest of the blank by an embossing line 12, along which the strip 11 is embossed to the rear, whereby in the finished wrapped jacket this strip protrudes by the material thickness on the inside of the container, while the two adjacent end sections of the jacket are aligned on the outside. In the area of this strip 11, the two cutting lines 8 and 9 run along the shape of a triangle 13, which lies under the handle 10 in the finished jacket and is sealed with it. When removing the handle, the cutting material is split along this triangle at the same time.

Beim Öffnen des Behälters reißt der Aufreißfaden den Mantel entlang der beiden Schnittlinien 8 und 9 auf, wobei durch die vorherige Materialspaltung im Bereich des Streifens 11 eine völlige Trennung der beiden Behälterabschnitte erfolgt.When the container is opened, the tear thread tears open the jacket along the two cutting lines 8 and 9, the two material sections being completely separated by the previous material splitting in the area of the strip 11.
