BeschreibunqDescription
Die Erfindung betrifft eine Verpackungshülle für die Portionierung eines trockenen, rehydratisierungsfähigen Nahrungsmittels und die Fertigzubereitung des Nahrungsmittels durch Kochen oder Backen, wobei das Material ein Folienmaterial und während des Kochvorgangs hitzebeständig ist und das Material weiter schrumpfbeständig ist und die Form im Schlauchbeutelsystem hergestellt ist.The invention relates to a packaging casing for portioning of a dry, rehydratable foodstuff and the finished preparation of the food by cooking or baking, the material being a sheet material and is heat-resistant during the cooking process and the material is further shrink-resistant and the shape is made in the tubular bag system.
Sie stellt eine weitere Ausführungsform der Verpackungshülle gemäß Patent , Patentanmeldung P 33 35 119.8 dar.It represents a further embodiment of the packaging casing according to Patent, patent application P 33 35 119.8.
Die Erfindung hat sich die Aufgabe gestellt, eine größere Variabilität der Schweißnaht zu erzielen, als dies bei der bisher üblicherweise verwendeten Schweißtechnik, der Impulsschweißung oder der Schweißung mit dauerbeheizten Schweißbacken möglich war.The invention has set itself the task of greater variability to achieve the weld seam than with the previously commonly used welding technology, pulse welding or welding with permanently heated welding jaws possible was.
Die Lösung dieser Aufgabe besteht darin, daß das Verschließen der Schlauchbeutel durch Ultraschallschweißung erfolgt ist.The solution to this problem is that the closure of the Tubular bag is made by ultrasonic welding.
Die Ultraschallschweißung von Folien ist grundsätzlich bekannt, findet jedoch noch keine sehr weit gehende Anwendung und insbesondere hat sie noch nicht Eingang in die Lebensmitteltechnik, z.B. für besondere Ausführungsformen für die maschinelle Serienabfüllung unter den dort notwendigen hygienischen Verbindungen gefunden.The ultrasonic welding of foils is basically known, finds however, it is not yet very widely used, and in particular has not yet been used Entry into food technology, e.g. for special designs for the Automated series filling with the necessary hygienic connections found.
Die für die Ultraschweißung geeigneten Kunststoffe sind bekannt. Im vorleigenden Fall werden Polypropylen und Polyvinylchlorid bevorzugt.The plastics suitable for ultrasonic welding are known. in the In the present case, polypropylene and polyvinyl chloride are preferred.
Bei der Ultraschallschweißung werden die zu verschweißenden Folien zwischen einem Schwingkopf und einem Amboß durchgeführt. Dabei werden die Folien durch innere Molekül reibung erhitzt und verschweißt. Diese Art der Verschweißung gestattet es nicht nur, die bisher durch die üblicherweise angewandten Schweißverfahren, Impulsschweißung bzw. Verschweirsung mit dauerbeheizten Schweißbacken mögliche Raffnaht oder das Verschließen im Seitenfaltverfahren durchzuführen, sondern ist wesentlich variabler in der Form der Schweißnaht.In the case of ultrasonic welding, the foils to be welded are performed between an oscillating head and an anvil. Thereby the foils Heated and welded by internal molecular friction. This type of welding Not only does it allow the welding processes commonly used to date, Impulse welding or welding with permanently heated welding jaws possible gathering seam or to perform the sealing in the gusset method, but is essential more variable in the shape of the weld seam.
So kann die Schweißnaht leicht unterbrochen und nach einer bestimmten Länge der Unterbrechung wieder fortgesetzt werden. Die Schweißnaht kann auch kompliziertere Formen auçwesen, wie Rundungen. Man kann durch relativ schwache Ut-raschallscElweißung eine Schwächungslinie in Längsrichtung durch das Material ziehen, wobei die Folie mittels Ultraschallschweißung so geschwächt wird (Kerbwirkung), daß sie einerseits dem Quellungsdruck bei der Zubereitung eines Knödels noch standhält, andererseits die Weiterreißfestigkeit der Folie jedoch deutlich erniedrigt wird.So the weld seam can be easily interrupted and after a certain Length of the interruption. The weld seam can also be more complicated Also forms, such as curves. One can through relatively weak ut-rasallic whitening Draw a line of weakness in the longitudinal direction through the material, whereby the film is so weakened by means of ultrasonic welding (notch effect) that on the one hand it can still withstand the swelling pressure during the preparation of a dumpling, on the other hand however, the tear strength of the film is significantly reduced.
Die Schwächungslinie in Längsrichtung kann auch gleichzeitig als Längssiegelnaht ausgebildet sein. The line of weakness in the longitudinal direction can also be used at the same time Be formed longitudinally sealed seam.
Demgemäß hat eine bevorzugte Ausführungsform der Hülle eine Quersiegelung mit unterbrochener Siegelnaht und Aufreißkerbe. Accordingly, a preferred embodiment of the envelope has a transverse seal with interrupted sealing seam and tear notch.
Nach einer weiteren bevorzugten Ausführungsform hat die HüLle eone runde bzw. ovale Schweißnaht und nach einer weiteren bevorzugten Ausführungsform besitzt sie eine Aufreißhilfe durch Materialschwächung mittels Ultraschalls rp7Pißling, beispielsweise eine Schwächungslinie, die s wh über den ganzen Umfang oder einen Teil des Umfangs der Huile erstreckt.According to a further preferred embodiment, the shell has a one round or oval weld seam and according to a further preferred embodiment it has a tear-open aid through material weakening by means of ultrasound rp7 pissing, for example a line of weakness that s wh over the entire circumference or a Part of the circumference of the Huile extends.
In der beigefügten Zeichnung zeigen Fig. 1 eine unterbrochene Quersiegelung Fig. 2 eine runde bzw. ovale Schweißnaht und Fig. 3 eine Aufreißhilfe durch Materialschwächung in Form einer Schwächungslinie über den Umfang der Hülle von Pol zu Pol.In the accompanying drawing, Fig. 1 shows an interrupted transverse seal FIG. 2 shows a round or oval weld seam and FIG. 3 shows a tear-open aid due to material weakening in the form of a line of weakness over the circumference of the envelope from pole to pole.
Da bei der Ultraschallschweißunghochfrequente elektrische Schwingungen in mechanische umgewandelt und durch eine Sonotrode in direkten Kontakt mit den zu fügenden Kunststoff übertragen werden, wird im Bereich der Resonanzfrequenz des gekoppelten System Sonotrode-Kunststoff-Amboß geschweißt. Die übliche Frequenz beträgt 40 kHz, kann aber je nach Packstoff 20 kHz betragen. Die Schweißleistung wird variiert durch den Abstand Sonotrode-Amboß und die Schweißzeit (0,1 bis 1 sec.) . Auf diese Weise ist diese Art der Schweißung sehr variabel und läßt sich von Hand oder automatisiert durchführen und ist zum Schweißen der meisten Thermoplasten geeignet.There are high-frequency electrical vibrations in ultrasonic welding converted into mechanical and through a sonotrode in direct contact with the The plastic to be joined is transferred in the range of the resonance frequency of the coupled system sonotrode-plastic anvil welded. The usual frequency is 40 kHz, but can be 20 kHz depending on the packaging material. The welding performance is varied by the distance between the sonotrode and the anvil and the welding time (0.1 to 1 sec.). To this This type of welding is very variable and can be done manually or automatically and is suitable for welding most thermoplastics.
