Description
"Kunststoffdose zum Verpacken von Lebensmitteln" Die üblichen metallischen Dosen zum Verpacken von Lebensmitteln, z. B. von Milch, Fischen, Gemüse, Marmelade usw. haben den Vorteil, dass man sie im geschlossenen Zustand zwecks Sterilisierung bzw. "Plastic jar for packaging food" The usual metallic ones Cans for packaging food, e.g. B. milk, fish, vegetables, jam etc. have the advantage that they can be closed for sterilization respectively.
Pasteurisierung ihres Inhalts erhitzen kann.Pasteurization can heat their contents.
Bei Kunststoffdosen, wie sie jetzt mehr und mehr in Gebrauch kommen, ist dies unmöglich oder doch schwierige weil die Bemperaturemptindlichkeit der meisten Materialien eine starke Erhitzung verbietet. Man hat deshalb Kunststoffpackungen für Lebensmittel bisher überwiegend nur dort angewendet, wo eine nachträgliche Sterilisation durch Wärme entbehrlich ist. Eine Ausnahme bildet lediglich die von der Anmelderin vorgeschlagene Verwendung von Polyäthylen bzw. Polytetrafluoräthylen, da diese Stoffe vergleichsweise hohe Temperaturen aushalten.In the case of plastic cans, as they are now being used more and more, is this impossible or at least difficult because the temperature sensitivity prohibits strong heating of most materials. That's why you have plastic packs for food so far mainly only used where a subsequent sterilization can be dispensed with due to heat. The only exception is that of the applicant proposed use of polyethylene or polytetrafluoroethylene, as these substances withstand comparatively high temperatures.
Nach vorliegender Neuerung wird dieser Gedankengang dahingehend weiter ausgebaut, dass man für Dosen der genannten Art in allgemeiner Weise isotaktisch aufgebaute, sterisoh orientierte Kunststoffe verwendet. Ein besonders brauchbarer Werkstoff dieser Natur ist das Polypropylen, das beispielsweise erst bei 160 - 170° C erweicht, so dass es den üblichen Sterilieiertemperaturen ohne weiteres ausgesetzt werden kann.According to the present innovation, this line of thought will continue to do so developed that one isotactically isotactic in a general way for doses of the type mentioned constructed, sterically oriented plastics are used. A particularly useful one A material of this nature is polypropylene, which, for example, only occurs at 160 - 170 ° C softens so that it is easily exposed to the usual sterilization temperatures can be.
Die isotaktischen Kunststoffe, die durch eine stereoapezifiaehe Polymerisation entstehen, bestehen aus Makromolekülen, die in einer bestimmten Weise räumlich gebaut sind, nämlich weitgehend kristallin und in sehr dichter Packung, so dass sich der Schmelzpunkt stark erhöht und die mechanischen Eigenschaften verbessert werden.The isotactic plastics produced by a stereoapezifiaehe polymerisation arise, consist of macromolecules that are built spatially in a certain way are, namely largely crystalline and very dense, so that the Melting point is greatly increased and the mechanical properties are improved.
Die Ausnutzung dieser Qualitäten, im besonderen Falle sterilisierfähiger Dosen, führt zu überraschenden Vorteilen, weil hierdurch den Kunststoffdosen ein weiter Anwendungsbereich auf dem Gebiet der Lebensmittel -verpackung erschlossen werden kann.The use of these qualities, in the special case more sterilizable Cans, leads to surprising advantages, because it is a plastic can wide area of application in the field of food packaging opened up can be.
In der Zeichnung ist die Neuerung beispielhaft dargestellt, und zwar in einem ganz schematischen Schnitt durch eine flache Konus endo Mit 1 ist die aus Polypropylen bestehende Dose bezeichnet, mit 2 ein aus gleichem Material gefertigter Deckel.In the drawing, the innovation is shown as an example, namely in a very schematic section through a flat cone endo with 1 is off Polypropylene called can, with 2 a made of the same material Lid.
Dieser Deckel kann aufgeschweißt, aufgeklebt oder augebördel werden und läset sich beispielsweise mit einer Reiüschnur 3 öffnen.This cover can be welded on, glued on or flanged on and can be opened with a pull cord 3, for example.
Natürlich eignen sich Dosen verschiedenster Form für die Ausbildung gemäß der Neuerung. Sie können rund oder eckig, flach oder tief, gleichförmig oder gestuft sein.Of course, cans of various shapes are suitable for training according to the innovation. They can be round or angular, flat or deep, uniform or be tiered.
