Description
Die Erfindung bezieht sich auf einen Kunstdarm für Wurst oder wurstähnliche Fleischwaren mit einer aufschrumpfbaren Kunststoffhaut.The invention relates to an artificial casing for sausage or sausage-like meat products with a shrinkable Plastic skin.
In der Vergangenheit wurden für solche Anwendungszwecke Natur därme eingesetzt, welche von Tierdärmen gewonnen wurden. Heutzutage werden jedoch üblicherweise aufschrumpfbare Kunst stoffmaterialien eingesetzt, da es zum einen schwierig war, größere Mengen an Naturdärmen zu erhalten und zum anderen Naturdärme den Bedarf bei großen maschinellen Produktionen nicht decken können.In the past, nature became natural for such applications intestines used, which were obtained from animal intestines. Nowadays, however, shrinkable art is usually used material materials because, on the one hand, it was difficult to get larger amounts of natural casings and on the other Natural casings meet the need for large machine productions cannot cover.
Gegenüber Naturdärmen haben Kunstdärme auf der Basis von aufschrumpfbaren plastischen Kunststoffmaterialien den Vorteil, daß sie sich bei einer Erhitzung des Produktes dessen Ausdehnung anpassen oder bei einem sich durch Abkühlung ergebenden Zusammenziehen der Fleischware entsprechend schrumpfen. Darüber hinaus ist das Kunststoffmaterial undurchlässig, so daß Flüssigkeitsverluste und das Eindringen von Bakterien oder anderen Mikroorganismen, welche die Fleischware verändern können, vermieden werden und somit die Haltbarkeit verlängert ist.Compared to natural casings, artificial casings based on shrinkable plastic plastic materials Advantage that when the product heats up Adjust expansion or in the case of cooling down resulting contraction of the meat product accordingly shrink. In addition, the plastic material impermeable, allowing fluid loss and penetration of bacteria or other microorganisms, which the Meat products can change, be avoided and thus the Shelf life is extended.
Da die Verbindung zwischen der Kunststoffhaut und der Wurst bzw. Fleischware dabei jedoch nicht besonders gut ist, läßt sich nicht verhindern, daß sich bei einer Erhitzung oder Abkühlung der bekannten Kunststoffhüllen zwischen diesen und dem Produkt Blasen oder Zwischenräume bilden.Because the connection between the plastic skin and the sausage or meat product is not particularly good, however do not prevent yourself from heating up or Cooling of the known plastic covers between them and form bubbles or gaps in the product.
Aufgabe der vorliegenden Erfindung ist daher, einen Kunstdarm der obengenannten Art zu schaffen, bei dem bei einer Erhitzung oder Abkühlung des Fleisches der Wurst oder dgl. Fleischwaren zwischen dem Fleisch und der Haut keine Blasen oder Zwischen räume entstehen.The object of the present invention is therefore an artificial intestine of the type mentioned above, in the case of heating or cooling the meat of the sausage or the like. Meat products no blisters or intermediate between the flesh and skin spaces arise.
Diese Aufgabe wird mit der Erfindung dadurch gelöst, daß die Kunststoffhaut eine aufschrumpfbare Nylonhaut ist, auf deren äußerer Oberfläche eine Beschichtung aus Polyäthylen und auf deren entgegengesetzter innerer Oberfläche eine an der Nylonhaut haftende oder aufgeklebte Schicht aus Polyvinyliden chlorid (PVDC) ausgebildet sind. Das Nylon gibt der Wursthülle dabei die notwendige Festigkeit, während das Polyvinyliden chlorid dafür verantwortlich ist, daß die Haut eng an dem Fleisch der Wurst oder dgl. Fleischwaren anliegt, damit zwischen dem Fleisch und der Haut keine Blasen oder Zwischen räume entstehen. Die äußere Polyäthylenschicht wiederum ist erforderlich, um die Kunststoffolie zur Bildung einer rohrförmigen Hülle verschweißen zu können.This object is achieved with the invention in that the Plastic skin is a shrinkable nylon skin on the outer surface a coating of polyethylene and on whose opposite inner surface is one on the Nylon skin adhesive or glued layer of polyvinylidene chloride (PVDC) are trained. The nylon gives the sausage casing doing the necessary strength while the polyvinylidene chloride is responsible for keeping the skin close to the skin Meat of the sausage or the like no blisters or intermediate between the flesh and skin spaces arise. The outer polyethylene layer is in turn required to form a plastic film to be able to weld tubular casing.
Aus der US 2,570,478 ist bereits ein Film mit einer Träger schicht aus einem Zellulosematerial und einer Beschichtung aus einem Copolymer mit einem Anteil Polyvinylidenchlorid. Damit soll das Problem gelöst werden, die Adhäsion der Beschichtung an der Trägerschicht auch bei hoher Feuchtigkeit zu gewähr leisten. Da der Zellulosefilm jedoch nicht feuchtigkeitsfest ist, ist der Film nicht zur Verwendung als Wursthaut geeignet. Auch läßt sich der Zellulosefilm nicht zu der rohrförmigen Hülle verschweißen, was beim Gegenstand der vorliegenden Erfindung aufgrund der Polyäthylenschicht ermöglicht wird. From US 2,570,478 is already a film with a support layer made of a cellulose material and a coating a copolymer with a portion of polyvinylidene chloride. In order to the problem is to be solved, the adhesion of the coating to guarantee on the carrier layer even in high humidity Afford. However, since the cellulose film is not moisture-proof the film is not suitable for use as sausage skin. Also, the cellulose film cannot be made into the tubular one Weld cover what is the subject of the present Invention due to the polyethylene layer is made possible.
In der US 3,353,992 ist eine Sperrschicht beschrieben, bei der Vinylidenchloridpolymere verwendet werden. Die Trägerschicht kann dabei ein Polyamid sein. Ein solches Material kann nicht heiß verschweißt werden, um eine schlauchförmige Hülle für Würste zu bilden.US Pat. No. 3,353,992 describes a barrier layer in which Vinylidene chloride polymers can be used. The backing layer can be a polyamide. Such a material cannot be heat welded to a tubular sleeve for To form sausages.
Gemäß besonderer Ausgestaltungen der vorliegenden Erfindung sind die Ränder der aufschrumpfbaren Nylonhaut zur Bildung eines im wesentlichen schlauchförmigen Gebildes entweder an ihrer Stirnseite miteinander verbunden oder überlappen sich im Verbindungsbereich aneinander haftend oder klebend und weisen ein haftend an ihrer äußeren Oberfläche gehaltenes bzw. aufgeklebtes die Ränder überlappendes Verbindungsband auf.According to special configurations of the present invention are the edges of the shrinkable nylon skin for formation of an essentially tubular structure either their front side connected or overlap sticking or sticking in the connection area and have an adhered to their outer surface or glued on the overlapping connecting tape.
Die Erfindung wird nachfolgend anhand zweier Ausführungsbei spiele und der Zeichnung näher beschrieben.The invention is illustrated below with the aid of two embodiments games and the drawing described in more detail.
Es zeigt:It shows:
Fig. 1 eine mögliche Ausführungsform eines erfindungsge mäßen Kunstdarms mit stirnseitig aneinander liegen den Rändern und Fig. 1 shows a possible embodiment of an artificial bowel according to the invention with the ends lying against each other and
Fig. 2 eine andere Ausführungsform eines erfindungsgemäßen Kunstdarms mit einer Verbindung aus überlappenden Rändern. Fig. 2 shows another embodiment of an artificial intestine according to the invention with a connection of overlapping edges.
Der erfindungsgemäße Kunstdarm ist als Mehrlagenschicht 1 aus gebildet, mit einer aufschrumpfbaren Nylonhaut 2 und einer äußeren Schicht oder Beschichtung 3 aus Polyäthylen und be sitzt auf seiner Innenseite eine über die aufschrumpfbare Nylonhaut 2 geklebte oder an ihr haftende Schicht 4, Beschich tung oder einen Film aus Polyvinylidenchlorid (PVDC).The artificial intestine according to the invention is formed as a multilayer 1 , with a shrink-fit nylon skin 2 and an outer layer or coating 3 made of polyethylene and be on its inside a layer 4 glued or adhered to the shrink-fit nylon skin 2 , coating or a film Polyvinylidene chloride (PVDC).
Die Ränder der den Kunstdarm bildenden Mehrlagenschicht 1 verbleiben, entweder stirnseitig miteinander verbunden (Fig. 1) oder sich überlappend (Fig. 2); in jedem Fall ist jedoch ihre Verbindung durch ein auf der Außenseite auf der Poly äthylenschicht 3 angeordnetes Verbindungsband 5 bewerkstel ligt, welches ebenfalls als Mehrlagenschicht ausgebildet ist, mit einer aufschrumpfbaren Nylonhaut 6 und einer Beschichtung 7 aus Polyäthylen, welche klebend auf der äußeren Beschichtung 3 aus Polyäthylen des Kunstdarms angeordnet ist. Selbstver ständlich kann das Verbindungsband 5 der den Kunstdarm bilden den Mehrlagenschicht 1 aus jedem anderen Material bestehen, welches auf der Außenseite des Kunstdarms unter Hitze dichtet.The edges of the multilayer layer 1 forming the artificial intestine remain, either connected to one another at the end face ( FIG. 1) or overlapping ( FIG. 2); in any case, however, their connection is accomplished by a connecting tape 5 arranged on the outside on the polyethylene layer 3 , which is also formed as a multilayer, with a shrinkable nylon skin 6 and a coating 7 made of polyethylene, which is adhesive on the outer coating 3 Polyethylene of the artificial intestine is arranged. Of course, the connecting band 5 of the artificial intestine can form the multilayer 1 from any other material which seals on the outside of the artificial intestine under heat.
