Die Erfindung betrifft ein Verfahren zur Vereinigung von Kautschukhydrochloridflächen, die insbesondere als Überzug der aus einem Werkstoff niedrigerer dielektrischer Verluste, vorzugsweise faseriger Cellulose, bestehenden Wand- und Bodenteile eines Behälters od. dgl. dienen. Nach der Erfindung wird dies dadurch erreicht, daß die zu vereinigenden Kautschukhydrochloridflächen unter Druck einem diese erweichenden Hochfrequenzfeld ausgesetzt werden.The invention relates to a method for combining rubber hydrochloride surfaces, in particular as a coating of a material with lower dielectric losses, preferably fibrous cellulose, existing wall and floor parts of a container or the like. Serve. According to the invention this is thereby achieved that the rubber hydrochloride surfaces to be united under pressure a softening them Exposed to high frequency fields.

Die Anwendung hochfrequenter elektrischer Wechselfelder mit und ohne Druckanwendung zur Erwärmung von Preßmassen, hochmolekularen Kunststoffen oder zur Vulkanisation von Kautschuk ist bekannt. Es war jedoch nicht vorauszusehen, ob auch zur Vereinigung von Kautschukhydrochloridflächen eine Hochfrequenzerhitzung durchführbar sei. Da das Kautschukmolekül ungesättigt ist und bei der Herstellung von Kautschukhydrochlorid eine doppelte Bildung eingeht, war vollkommen ungewiß, einerseits ob Kautschukhydrochlorid durch dielektrische Erwärmung genügend erweicht werden konnte, damit eine Verbindung benachbarter Flächen erzielt wurde, anderseits ob etwa durch Freiwerden der zugesetzten Salzsäure eine Zersetzung hervorgerufen würde. Bei der Lösung der Aufgabe, mit Kautschukhydrochlorid überzogene Cellulosegegenstände zu verbinden, war zudem nicht voraussehbar, ob bei der für das Erweichen des Kautschukhydrochlorids erforderlichen Stärke und Frequenz des Hochfrequenzfeldes nicht etwa gleichzeitig ein Verkohlen der ebenfalls in diesem Feld befindlichen Celluloseteile eintreten würde.The use of high-frequency alternating electrical fields with and without the application of pressure for heating molding compounds, high molecular weight plastics or the vulcanization of rubber is known. However, it could not be foreseen whether high-frequency heating would also be used to unite rubber hydrochloride surfaces is feasible. Because the rubber molecule is unsaturated and during manufacture of rubber hydrochloride enters into a double formation, it was completely uncertain whether, on the one hand, rubber hydrochloride by dielectric heating it could be softened enough to allow a connection adjacent areas was achieved, on the other hand, whether for example by releasing the added hydrochloric acid decomposition would be caused. In solving the problem, coated with rubber hydrochloride Joining cellulose objects was also not foreseeable whether it would be responsible for the softening of the Rubber hydrochloride required strength and frequency of the high-frequency field not approximately at the same time charring of the cellulose parts also located in this field would occur.

Die Erfindung kann vorzugsweise dazu dienen, Behälter oder Becher aus Cellulose mit einem Kautschukhydrochloridüberzug für Getränke, zur VerpackungThe invention can preferably be used to make containers or beakers made of cellulose with a rubber hydrochloride coating for beverages, for packaging

von Marmelade, Erdnußbutter od. dgl. mit einem Boden zu versehen. Die Kanten des Bodens und der unteren Wandung, die zylindrisch oder konisch sein kann, werden dabei so nach unten oder oben abgebogen, daß ausreichend große Berührungsflächen der Kautschukhydrochloridüberzüge, mit denen die aus •Cellulose gefertigten Behälterteile überzogen sind, gebildet werden.of jam, peanut butter or the like. To provide a base. The edges of the floor and the lower wall, which can be cylindrical or conical, are bent downwards or upwards, that sufficiently large contact areas of the rubber hydrochloride coatings with which the made • Cellulose-made container parts are coated, are formed.

In der Zeichnung ist ein Ausführungsbeispiel der ίο Erfindung dargestellt, und zwar zeigtIn the drawing, an embodiment of the invention is shown, namely shows

ao film überzogen, der aufgeklebt sein kann. Die obere Kante ist bei 3 umgerollt, um die für die Beibehaltung der Becherform nötige Steilheit zu erzielen. Der für den Becher vorgesehene Boden 4 ist auf der Innenseite ebenfalls mit einem Kautschukhydrochloridfilm 5 überzogen. Um eine innige Verbindung beider Teile zu ermöglichen, sind die Kanten des Bodenteiles 4, 5 sowie der unteren Seitenwandung 1, 2 bei 7 bzw. 6 derart lippenförmig abgebogen, daß die Lippe 7 des Bodens von dem von der Wandung 1 und ihrer Lippe 6 gebildeten Zwischenraum aufgenommen wird.ao film covered, which can be glued on. The top edge is rolled over at 3 to make for keeping to achieve the steepness required for the cup shape. The base 4 provided for the cup is on the inside also covered with a rubber hydrochloride film 5. About an intimate connection between the two parts to enable the edges of the bottom part 4, 5 and the lower side wall 1, 2 at 7 and 6, respectively bent lip-shaped in such a way that the lip 7 of the bottom is separated from that of the wall 1 and its lip 6 formed gap is recorded.

Um die Verbindung der beiden sich berührenden Kautschukhydrochloridflächen 2 und 5 mittels Hitzeklebung zu bewerkstelligen, dient die in Fig. 1 vorgesehene Vorrichtung, die bei Massenherstellung entsprechend abgeändert werden kann.Around the connection of the two contacting rubber hydrochloride surfaces 2 and 5 by means of heat bonding to accomplish, the provided in Fig. 1 device is used, the corresponding in mass production can be modified.

Der Bechermantel des Ausführungsbeispiels ist konisch gehalten. Um in einfacher Weise einen genügend starken Anpressungsdruck auf die Lippen 6 und 7 gegen die Becherwandung 1, 2 ausüben zu können, wird ein Weichgummiblock 10 benutzt, der auf einem Holzblock 11 aufgebracht ist. Wie Fig. 2 zeigt, ist im Ruhezustand der Durchmesser des Gummiblocks 10 um ein geringes kleiner als die Bodenöffnung des Bechers; ferner ist die Oberfläche 12 des Gummiblocks konisch ausgebildet. Wird nun durch den den Innenraum des Bechers ausfüllenden Kegelstumpf 15, der aus Holz bestehen kann, ein senkrechter Druck auf j die Oberfläche 12 des Gummiblocks ausgeübt, so legt sich der konische Teil flach gegen den Becherboden 4, der Durchmesser des Gummiblocks 10 vergrößert sich und übt dadurch einen seitlichen Druck auf die Lippen 6 und 7 aus. Der durch den Kegelstumpf 15 ausgeübte Druck wird durch eine in dem Joch 18 geführte und mit einem Handgriff 16 versehene Spindel 17 eingestellt. The cup jacket of the exemplary embodiment is kept conical. To get a sufficient amount in a simple way to be able to exert strong contact pressure on the lips 6 and 7 against the cup wall 1, 2, a soft rubber block 10, which is applied to a wooden block 11, is used. As Fig. 2 shows, in At rest the diameter of the rubber block 10 is slightly smaller than the bottom opening of the Mug; furthermore, the surface 12 of the rubber block is conical. Is now through the the interior of the cup filling truncated cone 15, which can consist of wood, a vertical pressure on j exerted the surface 12 of the rubber block, the conical part lies flat against the cup bottom 4, the diameter of the rubber block 10 increases and thereby exerts lateral pressure on the lips 6 and 7 off. The pressure exerted by the truncated cone 15 is guided by a pressure in the yoke 18 and spindle 17 provided with a handle 16 is set.

Der Heizring 19 am Boden des Bechers besteht aus einer in einem Isolierstoff 21 eingebrachten Kupferspule 20. Als Isolierstoff niedriger Leitfähigkeit und dielektrischer Verluste kann im einfachsten Fall Gips dienen. Die Spule 20 besteht, wie Fig. 1 zeigt, aus einem ziemlich dicken Metallband; ihre Mittelwindung ist im Durchmesser etwas kleiner als die obere und untere Windung gehalten und liegt bündig mit der Innenfläche des Heizringes. Die Spulenenden liegen nahe der linken Schnittfläche der Fig. 1 und sind an einem Hochfrequenzerzeuger angeschlossen. Die Cellulose wird nun durch das gebildete Hochfrequenzfeld kaum erhitzt, da sie einen verhältnismäßig geringen dielektrischen Widerstand besitzt. Der Kautschukhydrochlorid wird dagegen so stark erhitzt, daß die benachbarten Oberflächen 2 und 5 von Becherwandung bzw. -boden zusammenschmelzen.The heating ring 19 at the bottom of the cup consists of a copper coil inserted in an insulating material 21 20. In the simplest case, plaster of paris can be used as an insulating material with low conductivity and dielectric losses to serve. As FIG. 1 shows, the coil 20 consists of a fairly thick metal strip; their central turn is slightly smaller in diameter than the upper and lower turns and is flush with the Inner surface of the heating ring. The coil ends are close to the left cut surface of FIG. 1 and are on connected to a high frequency generator. The cellulose is now through the formed high frequency field hardly heated because it has a relatively low dielectric resistance. The rubber hydrochloride is heated so much that the adjacent surfaces 2 and 5 of the cup wall melt together or bottom.

Als Hochfrequenzerzeuger dient zweckmäßig ein Röhrenoszillator, der bei entsprechender Induktanz und Windungskapazität der Heizwicklung 20 ein Hochfrequenzfeld von 30 Megahertz liefert. Bei Verwendung von zwei Röhren der Type 806 (USA) in Gegentaktschaltung mit einem Anodenstrom von 200 Milliampere bei 3700 Volt und einem Gitterstrom von 75 Milliampere ergab sich ein genügend kräftiges Hochfrequenzfeld, um den Becherboden in 3 Sekunden zu befestigen.A tube oscillator, which with the appropriate inductance and turn capacitance of the heating coil 20 provides a high frequency field of 30 megahertz. Using of two type 806 tubes (USA) in push-pull circuit with an anode current of 200 milliamps at 3700 volts and a grid current of 75 milliamps resulted in a sufficiently strong one High frequency field to fix the cup bottom in 3 seconds.

Um eine auf der Seite der Spulenanschlüsse, also auf der linken Seite der Fig. 1, etwa vorhandene geringere Hitzeentwicklung auszugleichen, kann der Heizring 19 während des Betriebs etwas gedreht werden. Diese Schwierigkeit kann jedoch nicht auftreten, wenn die Wicklung des Heizringes mehrere an der Innenfläche des Ringes angeordnete Windungen besitzt, was den weiteren Vorteil hat, daß größere Flächen der benachbarten Kautschükhydrochloridfilme auf die erforderliche Temperatur erhitzt und zusammengeklebt werden können.By a smaller one on the side of the coil connections, that is to say on the left-hand side of FIG. 1, if any To compensate for the development of heat, the heating ring 19 can be rotated slightly during operation. However, this difficulty cannot occur if the winding of the heating ring has several on the inner surface of the ring has arranged turns, which has the further advantage that larger areas of the adjacent rubber hydrochloride films heated to the required temperature and glued together can be.

Becher und andere Behälter, die auf der Außenseite mit Kautschukhydrochlorid überzogen sind, können in entsprechender Weise erhitzt werden. Etwa auftretende Verunstaltungen der Außenfläche können durch Überkleben mit einem Etikett leicht verdeckt werden. Ist der Becher auf der Außenfläche glasiert, so muß die Hitze verbindung ohne Zerstörung der Glasur durchgeführt werden; dies läßt sich entsprechend dem Erfindungsvorschlag leicht durchführen, ohne daß dabei der Werkstoff der Behälterwandung erhitzt wird.Mugs and other containers that are coated on the outside with rubber hydrochloride can be put in be heated in a corresponding manner. Any blemishes on the outer surface can be caused by Sticking over with a label can be easily covered. If the beaker is glazed on the outside, it must the heat connection can be carried out without destroying the glaze; this can be done according to the invention proposal easily carried out without the material of the container wall being heated.
