Description
Verfahren zur Herstellung haltbarer Gelatinekapseln Es ist bekannt, Gelatinekapseln der verschiedensten Art, insbesondere für medizinische Zwecke, mit mehr oder weniger elastischer Wandung magen- oder darmlöslich herzustellen. Die Wände aller Gelatinekapseln werden jedoch vielfach in kürzerer oder längerer Zeit vom Kapselinhalt angegriffen und die Kapseln dadurch unansehnlich, wenn nicht gar, infolge der Auflösung der Kapselwand, unverwendbar. Besonders hygroskopische Materialien und Stoffe, die gegen Gelatine ohnehin nicht indifferent sind, wie Jod oder jodhaltige Verbindungen, vernichten die Kapselwandungen. Es ist bereits bekannt, Gelatine mit härtenden Stoffen zu behandeln. Weiterhin ist bekannt, zur Herstellung von Gelatinekapseln den Gelatinemassen so viel Alkalien oder Säuren zuzusetzen, daß die Gelatinemassen hierdurch gerade neutralisiert werden. Durch dieses Verfahren wird lediglich erreicht, daß die Kapseln neutral sind, jedoch werden sie hierdurch eicht haltbarer gegenüber Füllungen, die Gelatine angreifen. Das Wesen der vorliegenden Erfindung ist insofern neu, als sich nach ihr haltbare Gelatinekapseln auch mit an sich die Wandungen angreifenden bzw. zerstörenden Füllungen herstellen lassen. Der zur Herstellung der Wand dienenden Kapselmasse werden nämlich anorganische oder organische Säuren oder auch Gemische aus diesen, jeweils untereinander, oder Gemische aus anorganischen Säuren mit organischen Säuren zugesetzt, deren Menge nach Art der verwendeten Gelatine wechseln kann und von Fall zu Fall durch Versuche festgestellt werden muß. Die sonst übliche Zusammensetzung der Massen bedarf an sich keinerlei Abänderungen. Die aus derartigen Massen hergestellten Kapseln lassen sich in üblicher Weise in den verschiedensten Elastizitätsgraden oder auch hart, sowohl magen- als auch darmlöslich herstellen.Process for the production of durable gelatin capsules It is known Gelatin capsules of the most varied types, in particular for medical purposes, with more or less elastic wall to make gastric or intestinal soluble. the The walls of all gelatin capsules, however, are often in a shorter or longer time attacked by the contents of the capsule and the capsules become unsightly, if not at all, as a result of the dissolution of the capsule wall, unusable. Particularly hygroscopic materials and substances that are not indifferent to gelatine anyway, such as iodine or those containing iodine Connections destroy the capsule walls. It is already known to use gelatin to treat hardening substances. It is also known for the production of gelatin capsules to add enough alkalis or acids to the gelatin masses that the gelatin masses are just being neutralized by this. This process only achieves that the capsules are neutral, but this makes them more durable Fillings that attack gelatin. The essence of the present invention is so far new, when, according to her, durable gelatine capsules also attack the walls or have destructive fillings made. The one used to make the wall The capsule mass is namely inorganic or organic acids or mixtures from these, in each case with one another, or mixtures of inorganic acids with organic acids Acids added, the amount of which can change depending on the type of gelatin used and must be ascertained through tests on a case-by-case basis. The usual composition of the masses does not in itself require any changes. Those made from such masses Capsules can be made in the most varied of degrees of elasticity in the usual way or hard, both gastrointestinal and gastrointestinal.
Beispiele = kg Gelatinemasse aus z. B. 6oo g Gelatine wird mit =5 g einer 5o°/oigen Schwefelsäurelösung oder einer entsprechenden Menge Salzsäure oder 50 g einer 5o°/oigen Ameisensäure gleichmäßig versetzt und die so erhaltene Masse zur Herstellung von Gelatinekapseln verwendet.Examples = kg gelatin mass from z. B. 600 g of gelatin is evenly mixed with = 5 g of a 5o% sulfuric acid solution or a corresponding amount of hydrochloric acid or 50 g of a 5o% formic acid and the mass thus obtained is used to produce gelatin capsules.
