Description
Aus thermoplastischen Kunststoffmassen nach dem Spritz- oder Preßverfahren hergestellte Formkörper, insbesondere Christbaumschmuck Es ist bekannt, durchsichtige oder durchscheinende Glasgegenstände, z. B. Christbaumschmuck, auf der Innenseite zu verspiegeln, um diesen Gegenständen ein metallisch glänzendes Aussehen zu geben.Made of thermoplastic compounds using the injection or compression molding process Manufactured moldings, in particular Christmas tree decorations. It is known, transparent or translucent glass objects, e.g. B. Christmas tree decorations, on the inside mirrored to give these objects a shiny metallic appearance.
Glasgegenstände sind jedoch leicht zerbrechlich. Die Erfindung richtet sich auf Formkörper, die aus thermoplastischen Kunststoffmassen nach den bekannten Spritz- oder Preßverfahren hergestellt und die gegenüber Glas weitgehend bruchsicher sind. Gemäß der Erfindung bestehen diese Gegenstände aus durchsichtigem oder durchscheinendem Kunststoff und weisen auf ihrer Innenseite einen Spiegelbelag auf. Durchsichtige oder durchscheinende plastische Massen für die Verarbeitung nach den bekannten Spritz- oder Preßverfahren zu Kunststoffgegenständen sind im Handel bekannt. Der Spiegelbelag auf der Innenseite der gespritzten oder gepreßten Kunststoffgegenstände ist nach dem Amalgamverfahren oder mittels Silbernitratlösungen nach dem Niederschlagsverfahren erzeugt.However, glass objects are easily broken. The invention is directed on moldings made from thermoplastic materials according to the known Manufactured by injection or compression molding and largely unbreakable compared to glass are. According to the invention, these objects are made of transparent or translucent Plastic and have a mirror coating on their inside. See-through or translucent plastic masses for processing according to the known injection molding or molding processes to form plastic articles are known in the trade. The mirror covering on the inside of the molded or pressed plastic objects is after the amalgam process or by means of silver nitrate solutions according to the precipitation process generated.
Während sonst viele Kunststoffe nicht oder nicht in befriedigender Weise verspiegelbar sind, haben Versuche in überraschender Weise ergeben, daß die bekannten durchsichtigen oder durchscheinenden thermoplastischen Spritz- und Preßmassen . nach dem Amalgam- und mittels Silbernitratlösungen nach dem Niederschlagsverfahren verhältnismäßig leicht verspiegelbar sind.While otherwise many plastics do not or not in a satisfactory manner Are mirrorable way, experiments have surprisingly shown that the known transparent or translucent thermoplastic injection and molding compounds . after the amalgam and by means of silver nitrate solutions after the precipitation process are relatively easy to mirror.
Die Erfindung findet vorzugsweise Anwendung für Gegenstände aus den genannten plastischen Massen, die geschlossene Hohlkörper bilden, wie z. B. Christbaumschmuck, deren Innenseite auf die erwähnte Art verspiegelt ist. Diese Hohlkörper sind durch die Zusammenfügung von zwei oder mehreren gespritzten oder gepreßten und vor der-Zusammenfügung innen verspiegelten Einzelteilen gebildet. Die Innenseite dieser geschlossenen Hohlkörper ist nach der Zusammenfügung nicht mehr zugänglich, so daß dort der Spiegelbelag gegen mechanisches Abreiben und wegen der vollständig geschlossenen Form auch gegen die schädliche Einwirkung von Feuchtigkeit und Luft (Oxydation u. dgl.) geschützt ist.The invention is preferably used for objects from the called plastic masses that form closed hollow bodies, such as. B. Christmas tree decorations, the inside of which is mirrored in the aforementioned way. These are hollow bodies by the assembly of two or more injection molded or pressed and pre-assembly mirrored parts inside. The inside of this closed hollow body is no longer accessible after assembly, so that the mirror coating there against mechanical abrasion and because of the completely closed shape also against the harmful effects of moisture and air (oxidation, etc.) are protected is.
Die Abb. i veranschaulicht in teilweisem Schnitt als Ausführungsbeispiel eine gemäß der Erfindung hergestellte Christbaumhohlkugel: Sie besteht aus , den beiden miteinander dicht verklebten oder verkitteten Halbkugelhälften i und 2, deren Innenseite den Spiegelbelag 3 aufweist. Der Aufhängefaden 4 ist durch Festklemmen zwischen den beiden Kugelhälften befestigt.Fig. I illustrates in partial section as an embodiment a hollow Christmas tree ball produced according to the invention: It consists of, the two hemispherical halves i and 2, which are tightly glued or cemented to one another, their Has the mirror coating 3 on the inside. The hanging thread 4 is by clamping attached between the two halves of the ball.
Soweit die Spiegelschicht jedoch einer Berührung bei mehr oder weniger offenen Gegenständen frei zugänglich ist, ist diese durch eine besondere Schutzschicht, z. B. eine Lackierung, gegen Abreiben und Oxydation geschützt. Die Abb. 2 zeigt hierzu in teilweisem Schnitt als Ausführungsbeispiel einen die Form einer Glocke aufweisenden Christbaumschmuck. Der aus durchsichtigem Kunststoff gespritzte oder gepreßte Glockenkörper 6 trägt auf seiner Innenseite den Spiegelbelag 7, auf dem die besondere Schutzschicht 8 angebracht ist.As far as the mirror layer, however, a touch with more or less is freely accessible to open objects, this is protected by a special protective layer, z. B. a paint, protected against rubbing and oxidation. Fig. 2 shows this in a partial section as an exemplary embodiment the shape of a bell exhibiting Christmas tree decorations. The transparent plastic injection-molded or pressed bell body 6 carries on its inside the mirror coating 7 on which the special protective layer 8 is attached.
Die innen verspiegelte Wandung der Kunststoffgegenstände weist vorteilhaft Vertiefungen und/oder Erhebungen 9 (Abb. i und 2) in Form von Lichtbrechfacetten, Gravuren, Mattierungen u. dgl. auf, die durch die entsprechend ausgestaltete Spritz-oder Preßform erzeugt sind.The internally mirrored wall of the plastic objects has advantageous Depressions and / or elevations 9 (Fig. I and 2) in the form of refractive facets, Engravings, matting and the like, which by the appropriately designed spray or Mold are generated.
Bei aus zwei oder mehreren Formteilen zusammengesetzten Gegenständen ist die Gravur, Mattierung o. dgl. vorzugsweise an der Trennlinie am Rande der Formteile angebracht, weil dort bei der Verspiegelung der Formteile sich leicht Unregelmäßigkeiten bilden, die durch die Gravur, Mattierung o. dgl. nicht mehr störend in die Erscheinung treten. Daher ist auch bei der Ausführungsform nach Abb. i am Rande entlang der Trennlinie 5 der beiden Halbkugelhälften i und 2 eine Gravur 9 angebracht, die durch eine Quergravur bildmäßig zu einem Stern ergänzt ist' Hierdurch tritt auch die Trennlinie selbst nicht mehr störend hervor. Die Erfindung erstreckt sich auf Gebrauchsgegenstände, Zier- und Schmuckgegenstände aller Art, die aus durchsichtigen oder durchscheinenden .plastischen Massen nach den bekannten Spritz- und Preßverfahren hergestellt sind und denen durch die Verspiegelung das Aussehen von hochglänzenden oder mattglänzenden Metallgegenständen gegeben wird. Der durchsichtige oder durschscheinende Werkstoff kann zur Erzielung einer farbigen Spiegelwirkung gefärbt sein.In the case of objects composed of two or more molded parts is the engraving, matting or the like. Preferably on the dividing line at the edge of the molded parts attached because there are easily irregularities in the mirroring of the molded parts form, which by the engraving, matting or the like. No longer disturbing the appearance step. Therefore, also in the embodiment according to Fig. I at the edge along the Dividing line 5 of the two hemispheres i and 2 an engraving 9 attached through a cross engraving is added to a star 'This is where the dividing line appears itself no longer disturbing. The invention extends to objects of daily use, Ornaments and ornaments of all kinds made of transparent or translucent .plastic masses are produced by the known injection and pressing processes and those with the mirror coating the appearance of high-gloss or matt-gloss Metal objects is given. The transparent or translucent material can be colored to achieve a colored mirror effect.
