Description

Füllfederhalter mit im durchscheinenden Licht durchsichtigem, im auffallenden Licht undurchsichtigem Schaft Es ist allgemein bekannt, Füllfederhalter mit einem durchsichtigen Teil auszuführen, damit man den Stand der Tinte sehen kann. Im übrigen sucht man aber dem Füllfederhalter ein möglichst ruhiges Aussehen zu geben, indem man die übrigen Tintenkanäle sowie die 11echanik in undurchsichtigen Teilen unterbringt. Auch der durchsichtige Teil wurde schon so ausgeführt, daß er nur in durchscheinendem Licht durchsichtig wirkt, dagegen in auffallendem Licht undurchsichtig erscheint.Fountain pen with transparent in the shining light, in the conspicuous It is well known to use a fountain pen with a light opaque barrel transparent part so that you can see the level of the ink. Furthermore but one tries to give the fountain pen as calm an appearance as possible by the remaining ink channels and the mechanics are housed in opaque parts. Even the transparent part has already been designed in such a way that it can only be seen through Light appears transparent, but appears opaque in incident light.

Die Erfindung betrifft einen solchen Füllfederhalter mit im durchscheinenden Licht durchsichtigem, dagegen im auffallenden Licht undurchsichtigem Schaft aus in der Grundmasse durchsichtigem Kunststoff, bei dem diese Eigenschaft auf eine neuartige Weise erreicht ist. Gemäß der Erfindung wird die durchsichtige bzw. undurchsichtige Eigenschaft des Schaftes durch Einbettung von 1-tetallst.aufi in die Kunststolfgrundmasse bewirkt. Gegenüber den bisherigen Möglichkeiten, Füllfederhalter mit den vorgenannten Eigenschaften herzustellen, ergibt sich durch die Erfindung ein erheblicher Fortschritt, da bisher die Schäfte der Füllfederhalter zur Erreichung der vorgenannten Eigenschaften entweder in besonderen \."erfahren aus verschiedenen Grundteilen hergestellt werden mußten oder die Schäfte noch zusätzlich nachbearbeitet wurden. Es ist nach der Erfindung möglich, den ganzen Halterschaft aus einem einzigen Stück ohne zusätzliche Nachbearbeitung herzustellen, indem eine an sich, bekannte durchsichtige Spritzgußmass,e zur Herstellung des Halterschaftes verwendet wird, die sich nur durch die erfindungsgemäße Beimischung von Metallstaub von den bisher verarbeiteten Kunststoffgrundmassen unterscheidet.The invention relates to such a fountain pen with in the translucent The shaft is transparent in light, but opaque in incident light in the basic mass transparent plastic, in which this property on a novel way is achieved. According to the invention, the transparent or opaque Property of the shaft due to the embedding of 1-tetallst.aufi in the plastic base material causes. Compared to the previous options, fountain pens with the aforementioned To produce properties, results from the invention a considerable advance, since so far the shafts of the fountain pens to achieve the aforementioned properties either in special \. "are made from different basic parts had to or the shafts were additionally reworked. It is according to the invention possible, the entire holder shaft from a single piece without additional post-processing produce by a per se, known transparent injection molding compound, e for production of the holder shaft is used, which is only due to the admixture according to the invention of metal dust differs from the previously processed plastic base materials.
