Description

Die Erfindung betrifft eine Vorrichtung zum Versiegeln von Töpfen oder dergleichen Gefäßen miteinander, die aus Kunststoff bestehen, beispielsweise aus Polypropylen, Polystyrol, PVC, ABS und dergleichen. Mit der Vorrichtung wird eine Verpackung ausgebildet, die nach dem Befüllen des Gefäßes mit einem flüssigen oder festen Produkt mit­ samt dem Deckel versiegelt wird. Die Versiegelung be­ steht im wesentlichen aus einem Ring, in dem radial ver­ teilt mehrere rechtwinklige Nadeln vorgesehen sind, die über eine elektrische Widerstandsheizung beheizt werden, die in dem Ring untergebracht ist.The invention relates to a device for sealing Pots or similar vessels with each other, made from Plastic, for example made of polypropylene, Polystyrene, PVC, ABS and the like. With the device a packaging is formed, which after filling with a liquid or solid product is sealed together with the lid. The seal be essentially consists of a ring in which radial ver shares several right angle needles that are provided are heated by an electrical resistance heater, which is housed in the ring.

Zum besseren Verständnis der Erfindung wird diese im fol­ genden anhand der beigefügten Zeichnungsfiguren näher erläutert. Es zeigt:For a better understanding of the invention, this is in fol genden with reference to the accompanying drawing figures explained. It shows:

Fig. 1 eine Unteransicht der Versiegelungs­ vorrichtung; Fig. 1 is a bottom view of the sealing device;

Fig. 2 eine teilweise geschnittene Seitenansicht einer Verpackung, bestehend aus aufein­ ander gesetzten Töpfen, wobei sich beabstandet darüber die Abdichtvorrichtung in ihrer Betriebslage befindet. Fig. 2 is a partially sectioned side view of a package consisting of pots placed on each other, with the sealing device spaced above it in its operating position.

Die Versiegelungsvorrichtung für Töpfe, Becher und der­ gleichen Gefäße weist einen rohrförmigen Ring 10 aus Me­ tall mit rechteckigem Querschnitt auf, in dem eine Krone elektrischer Widerstandsheizungen 11 angeordnet ist, die eine Reihe von sich rechtwinklig erstreckenden Nadeln 12 heizen, die ringförmig an der Rückseite oder Unterseite des Rings 10 angeordnet sind.The sealing device for pots, cups and the same vessels has a tubular ring 10 made of metal with a rectangular cross-section, in which a crown of electrical resistance heaters 11 is arranged, which heat a series of perpendicularly extending needles 12 , which are ring-shaped on the back or Bottom of the ring 10 are arranged.

Das Abdichten bzw. Versiegeln erfolgt entsprechend Fig. 2 bei befülltem Topf 13, der mit einem Topf 14 verschlossen ist, wodurch eine fertige Verpackung ausgebildet wird. Die Versiegelungsvorrichtung wird dann vertikal über der Ver­ packung angeordnet, wobei die rechtwinkligen Nadeln 12 auf eine kontrollierte Temperatur erwärmt werden derart, daß sie den Topf 14 und die entsprechende Kante des Topfs 13 perforieren, wenn die Versiegelungsvorrichtung nach unten bewegt wird. Nach dem Perforieren wird die Ver­ siegelungsvorrichtung sofort nach oben gezogen und die Nadeln 12 werden aus ihrem Kontakt mit der Verpackung herausgezogen.The sealing or sealing takes place according to FIG. 2 with a filled pot 13 , which is closed with a pot 14 , whereby a finished packaging is formed. The sealing device is then placed vertically over the package, with the right-angled needles 12 being heated to a controlled temperature such that they perforate the pot 14 and the corresponding edge of the pot 13 when the sealing device is moved down. After perforating, the sealing device is immediately pulled upwards and the needles 12 are pulled out of their contact with the packaging.

Das Schmelzen des Materials des Topfes 14 und des Topfs 13 und das darauf folgende Abkühlen erzeugt eine Abdichtung bzw. Versiegelung an mehreren Punkten des Materials. Um die Versiegelung aufzubrechen ist es notwendig, einen be­ trächtlichen Druck auf den Topf 14 auszuüben, was nur beim ersten, willentlichen Öffnen des Topfes 13 geschieht.The melting of the material of the pot 14 and the pot 13 and the subsequent cooling creates a seal at several points of the material. In order to break the seal, it is necessary to exert considerable pressure on the pot 14 , which only happens when the pot 13 is opened for the first time.

Die Versiegelungsvorrichtung soll eine geeignete Größe für jeden Typ und für jedwede Verwendung der Verpackung haben, und die Betriebstemperatur und auch die Anzahl der Nadeln 12 und der jeweils angewendete Druck hängen grundsätzlich von den physikalisch-chemischen Eigenschaften des Ver­ packungsmaterials ab.The sealing device should be of a suitable size for each type and for any use of the packaging, and the operating temperature and also the number of needles 12 and the pressure used in each case depend fundamentally on the physico-chemical properties of the packaging material.

Durch diese Konstruktion ist eine praktische und einfache Garantie für die Unverletzlichkeit des in der Verpackung verpackten Produktes gegeben, ohne daß eine zusätzliche Dichtung für den Topf 13 vorgesehen werden muß.This construction provides a practical and simple guarantee for the inviolability of the product packaged in the packaging, without the need for an additional seal for the pot 13 .
