  Verfahren zur Herstellung eines dauernd feucht bleibenden giftfreien Fliegenpapieres unter Verwendung von Quassiaholzextrakt. 



   Nach dem Verfahren gemäss der Erfindung wird zerkleinertes Quassiaholz in   verdünntem   Glyzerindigeriert und mit der abgeseihten Flüssigkeit starkes ungeleimtes Papier getränkt. 



   Gegenüber den Eigenschaften und Herstellungsweisen der bisher bekannten giftfreien Fliegenpapiere unterscheidet sich das vorliegende Herstellungsverfahren dadurch, dass das zerkleinerte Quassiaholz nicht abgekocht und auch nicht mit Alkohol behandelt wird, sondern die Bitterstoffe desselben durch Glyzerin, zufolge des grossen Lösungsvermögens des letzteren, ausgezogen werden. Ein weiteres wesentlich unterscheidendes Merkmal des gegenständlichen Verfahrens gegenüber den bisher bekannten Verfahren liegt darin, dass das mit der nach obiger Vorschrift erhaltenen Flüssigkeit getränkte Papier infolge der hygroskopischen Eigenschaft des verwendeten   Glyzerins   dauernd feucht bleibt und das Fliegenpapier nicht wie bisher zum Gebrauch erst angefeuchtet werden muss.

  Process for the production of a permanently moist, non-toxic fly paper using quassia wood extract.



   According to the method according to the invention, crushed quassia wood is digested in dilute glycerine and strong unsized paper is soaked with the liquid which has been separated off.



   Compared to the properties and manufacturing methods of the previously known non-toxic fly papers, the present manufacturing process differs in that the crushed quassia wood is neither boiled nor treated with alcohol, but the bitter substances of the same are extracted by glycerine, due to the great dissolving power of the latter. Another essential distinguishing feature of the present method compared to the previously known method is that the paper soaked with the liquid obtained according to the above procedure remains permanently moist due to the hygroscopic property of the glycerine used and the fly paper does not have to be moistened before use.
