Abstract

In a heat-sealable container (1), the seal seam (5) of which has a closed contour and the lid (3) of which has a pull tab (4), the seal seam has at one point a bulge which is formed by two straight seam sections (6, 6a). The two seam sections enclose an angle of between 60 DEG and 120 DEG . The apex (7) of the angle points in the direction of the pull tab (4). <IMAGE>

Description

Gegenstand der Erfindung ist ein heißversiegelbarer Behälter, dessen Siegelnaht eine geschlossene Kontur mit Ausbuchtung aufweist.The invention relates to a heat-sealable container, the sealing seam of which has a closed contour with a bulge.

Bei den bekannten mittels Siegelnaht verschlossenen Behältern aus siegelfähigem Kunststoff oder aus einem mit siegelfähigem Kunststoff kaschiertem Metall ist die Kontur der Naht vollkommen stetig ausgebildet, d.h. sie ist kreisförmig bei zylindrischen Behältern und viereckig mit abgerundeten Ecken bei quadratischen oder rechteckigen Behältern. Der Betrag der Kraft, der zum Aufreißen einer Siegelnaht erforderlich ist, ist proportional der Nahtstrecke, an die die Kraft angreifen muß. Diese Nahtstrecke ist bei den bekannten Nahtkonturen bei erstem Anreißen - Anreißen bedeutet, die Naht soweit aufreißen, daß eine Verbindung zwischen Außen- und Innenraum des Behälters hergestellt ist - besonders groß und wird mit zunehmendem Raaius der Kontur immer größer. Die Kraft zum Anreißen der Naht kann deshalb ein Vielfaches dessen betragen, was zum Aufreißen der angerissenen Naht noch notwendig ist.In the known containers made of sealable plastic or of a metal laminated with sealable plastic, sealed by means of a sealed seam, the contour of the seam is completely continuous, that is to say it is circular in the case of cylindrical containers and square with rounded corners in the case of square or rectangular containers. The amount of force required to tear a sealed seam is proportional to the seam distance to which the force must act. In the known seam contours, this seam section is particularly large when tapping for the first time - tapping means tearing open the seam to such an extent that a connection is established between the outside and the interior of the container - and becomes increasingly larger with increasing contour. The force for tearing the seam can therefore be a multiple of what is still necessary to tear the torn seam.

Es bestand demnach die Aufgabe, einen heißversiegelbaren Behälter zu schaffen, bei dem die Kraft zum Anreißen der Siegelnaht größenordnungsmäßig nicht größer ist als die aufzubringende Kraft zum Aufreißen der Naht nach erfolgtem Anriß.It was therefore the task of creating a heat-sealable container in which the force for tearing the sealing seam is not of an order of magnitude greater than the force to be torn open for the seam after the tearing.

Die Aufgabe wird durch einen heißversiegelbaren Behälter gelöst, dessen Siegelnaht eine geschlossene Kontur und dessen Deckel eine Reißlasche aufweist, der dadurch gekennzeichnet ist, daß die Siegelnaht an einer Stelle eine Ausbuchtung besitzt, die durch zwei gerade Nahtabschnitte gebildet wird, wobei die beiden Nahtabschnitte einen Winkel von 60° bis 120° bilden.The object is achieved by a heat-sealable container, the sealing seam of which has a closed contour and the lid of which has a tear tab, which is characterized in that the sealing seam has a bulge at one point, which is formed by two straight seam sections, the two seam sections forming an angle form from 60 ° to 120 °.

Besonders vorteilhaft ist ein winkel von 90°, dessen Scheitel in Richtung Reißlasche zeigt.An angle of 90 °, the apex of which points towards the pull tab, is particularly advantageous.

Durch die erfindungsgemäße Ausbuchtung der Siegelnaht werden die Kräfte zum Anreißen der Naht über den Scheitel der Ausbuchtung in die Naht eingeleitet und erreichen im weiteren Verlauf des öffnens lediglich die Größenordnung der Kräfte, die zum Aufreißen der vollständig angerissenen Naht erforderlich sind.Due to the bulge of the sealing seam according to the invention, the forces for tearing the seam are introduced into the seam via the apex of the bulge and, in the further course of the opening, only achieve the magnitude of the forces which are required for tearing the completely torn seam.

Die Erfindung wird im Folgenden anhand der Figuren in beispielsweiser Ausführung näher erläutert.

  • Figur 1 zeigt eine Draufsicht des Behälters.
  • Figur 2 zeigt eine Seitenansicht des Behälters mit teilweise aufgerissenem Deckel.
The invention is explained in more detail below with reference to the figures in an exemplary embodiment.
  • Figure 1 shows a top view of the container.
  • Figure 2 shows a side view of the container with the lid partially torn.

Der Behälter 1 mit auskragendem Rand 2 ist mit einem Dekkel 3, der eine Reißlasche 4 aufweist, versiegelt. Behälter und Deckel bestehen entweder aus heißsiegelfähigem Material oder sind mit einem solchen kaschiert, wenn Behälter und/oder Deckel aus Metall bestehen. Die Siegelnaht 5 ist mit einer Ausbuchtung, die durch die geraden Nahtabschnitte 6 und 6 a gebildet wird, versehen. Der Scheitel7 der Ausbuchtung weist in Richtung Reißlasche 4.The container 1 with a cantilevered edge 2 is sealed with a lid 3 which has a tear tab 4. Containers and lids are either made of heat-sealable material or are laminated with one if the container and / or lid are made of metal. The sealing seam 5 is provided with a bulge, which is formed by the straight seam sections 6 and 6 a. The apex 7 of the bulge points in the direction of the pull tab 4.
