Die bisher hergestellten derartigen Behälter besitzen ein ein ungleichmäßiges Aussehen infolge unerwünschter Vartionen in der Länge der röhrenförmigen Wandung, die nach einwärts gebogen ist, wobei derartige Unregelmäßigkeiten besonders auffallen und unangenehm sind, wenn der röhrenförmige Hauptteil und das Endstück aus verschieden gefärbten Stoffen bestehen. The containers of this type produced hitherto have a non-uniform shape Appearance due to undesirable variations in the length of the tubular wall, which is bent inwards, such irregularities being particularly noticeable and are inconvenient when the tubular main part and the end part are made different colored fabrics.
Die Erfindung besteht bei einem derartigen Behälter aus thermoplastischem Material, der einen umlaufenden Bund aufweist, der ueber dem ringförmigen Rand eines Endetücks liegt, darin, daß der oben liegende Bund in einem aufwärts gekehrten Rand endigt und eine ringförmige Rippe bildet, die ueber die obere Fläche des Hauptstttckes vorsteht. Die Lage der Rippe wird durch die Form des sur Herstellung verwendeten Werkzeugs bestimmt und ist daher bei allen hergestellten Behältern gleich. In such a container, the invention consists of a thermoplastic material Material that has a circumferential collar that extends over the annular edge of a The end piece lies in the fact that the upper collar is in an upward-facing edge ends and forms an annular rib that extends over the upper surface of the main piece protrudes. The location of the rib is determined by the shape of the sur making used Tool and is therefore the same for all manufactured containers.
Die Erfindung betrifft auch eine Vorrichtung zur Herstellung des erfindungsgemäßen Behälters, der aus einem vorgeformten rohrförmigen Hauptstllok und einem vorgeformten EndstUck besteht, die beide miteinander verschweißt sind. Die Vorrichtung besteht aus einem Dorn, der das EndstUck an dessen oberem Ende stützt und der in das rohrförmige Hauptstück eingepaßt iet, wobei das Sunde des Hauptsttlckes Ueber das Ende des Kopfstückes Ubersteht, ferner aus einem axial in Richtung auf den Dorn zu bewegenden Formwerkzeug, mit dessen Hilfe die Überstehenden Teile des Hauptstückes nach innen gebogen werden und mit der Oberfläche des topfstUokea verschweißt werden. Diese Vorrichtung ist dadurch gekennzeichnet, daß das Pormwerkzeug eine ringförmige Jut aufweist, um den äußeren Rand des Hauptstückes aufzunehmen und nach außen zu wenden, wodurch die radiale Breite des eingebogenen Teils des HauptstUcks genau festgelegt wird und die vorstehende ringförmige Rippe auf der oberen Fläche des fertigen Behälters gebildet wird. The invention also relates to an apparatus for producing the Container according to the invention, which consists of a preformed tubular main locomotive and a preformed end piece, both of which are welded together. The device consists of a mandrel that supports the end piece at its upper end and which is fitted into the tubular body with the bottom of the body Over the end of the head piece protrudes, also from an axially in the direction of the mandrel to be moved molding tool, with the help of which the protruding parts of the The main piece is bent inwards and welded to the surface of the topfstUokea will. This device is characterized in that the Pormwerkzeug a has annular jut to accommodate the outer edge of the main piece and after outside, reducing the radial width of the inflected part of the main piece is precisely defined and the protruding annular rib on the upper surface of the finished container is formed.
Eine Reihe von AusfUhrungaformen der Erfindung werden als Beispiele in der beigefügten Zeichnung erläutert. In dieser zeigt: Fig. 1 einen Bxialechnitt durch eine Form einer Vorrichtung, die zur Herstellung von erfindungsgemäßen Behältern verwendet werden kann, wobei die beiden Hälften der Figur verschiedene Stadien in der Arbeitsweise der Vorrichtung zeigen; Fig. 2 zeigt einen halbschnittförmigen Aufriß des Behälters der mit der Vorrichtung von Fig. 1 erzeugt wurde. A number of embodiments of the invention are given as examples explained in the accompanying drawing. In this: Fig. 1 shows a bxial view by one form of apparatus used for the manufacture of containers according to the invention can be used, with the two halves of the figure in different stages show the operation of the device; Fig. 2 shows a semi-sectional Elevation of the container produced with the apparatus of FIG.
Bei der in Fig. 1 erläuterten Ausführungsform zur Verwirklichung der Erfindung wird ein vorgeformtes Endstück 1 von dem entsprechend geformten zieren Ende eines Netallkerns oder Dorns 2 getragen und um diesen Dorn 2 ist ein röhrenförmiges HauptstUck 3 gelegt, dessen oberes Ende vorspringt, wie bei 4 auf der rechten Seite der Fig. 1 gezeigt wird. Der den körper 3 und das EndstUck 1 tragende Dorn wird dann axial bewegt zum Eingriff in ein oberes Werkzeug 5 in Borm einer Abzugshaube oder Schale. Dieses Werkzeug besteht aus einem äußeren Ring 6 aus nichtmetallischem Material und einem inneren Metallteil 7, der ein Schweißwerkzeug darstellt. Die innere Oberfläche des Rings 6 ist so geformt, daß sie, wenn die Teile 2 und 5 aufeinander zu bewegt werden, den vorspringenden oberen Rand des röhrenförmigen Hauptteils einrückt und nach innen umwendet. In the embodiment illustrated in FIG. 1 for implementation of the invention will decorate a preformed end piece 1 of the correspondingly shaped End of a metal core or mandrel 2 carried and around this mandrel 2 is a tubular HauptstUck 3 laid, the upper end of which protrudes, as with 4 on the right side of Fig. 1 is shown. The mandrel carrying the body 3 and the end piece 1 is then moved axially to engage an upper tool 5 in the form of a hood or shell. This tool consists of an outer ring 6 made of non-metallic Material and an inner metal part 7, which is a welding tool. the inner surface of the ring 6 is shaped so that when the parts 2 and 5 are on top of each other to be moved, engages the protruding upper edge of the tubular main part and turned inside.
Bei einer weiteren relativen Bewegung der Teile 2 und 5 werden das Endstück 1 und dieser nach innen umgewendete Teil des Hauptatücks 3 zwischen dem Werkzeug 5 und der oberen Fläche des Dorns 2 fest zusammengepreßt. Das Verschweißen der Teile 1 und 3 wird vorzugsweise mit elektrischen Hochfrequenzströmen ausgeführt, wobei der Dorn 2 und der Metallteil 5 des Preßformwerkzeugs als Elektroden dienen.With a further relative movement of parts 2 and 5, the End piece 1 and this inwardly turned part of the main piece 3 between the Tool 5 and the upper surface of the mandrel 2 firmly pressed together. The welding parts 1 and 3 are preferably carried out with high-frequency electrical currents, wherein the mandrel 2 and the metal part 5 of the compression molding tool serve as electrodes.
Erfindungsgemäß ist die innere Oberfläche der Preßformelektrode 7 so geformt, daß sie eine ringförmige Vertiefung 9 aufweist, die (wie auf der linken Seite von Fig. 1 geseigt wird) den äußersten Rand 10 des Hauptkörperrohres aufnimmt, wenn es nach innen gebogen wird und eine weitere Einwärtsbewegung der Rohrwandung verhindert. Die Oberfläche der Elektrode an der Innenseite der Vertiefung kann glatt sein und kann mit der Oberfläche auf der außenseite der Vertiefung eine gerade Linie bilden. Am Innenrand der Vertiefung in der Elektrodenobertläche kann jedoch auch eine Stufe angeordnet sein, die bei 11 gezeigt wird. Diese Stufe hilft mit, die einwärtsgerichtete Bewegung des Rohrrandeg aufzuhalten und den Rand nach außen in die ringförmige Vertiefung su lenken. Die Stufe kann kontinuierlich ausgebildet sein, aber wie gezeigt ist, besteht sie aus den Enden der radial angeordneten Leisten 12 auf der Elektrodenoberfläche, die auf der äußeren Oberfläche des Endstückes beim Verschweißen entspreohende dekorative Vertiefungen erzeugen. According to the invention, the inner surface of the die electrode 7 is shaped so that it has an annular recess 9, which (as on the left Side of Fig. 1) receives the outermost edge 10 of the main body tube, when it is bent inward and further inward movement of the pipe wall prevented. The surface of the electrode on the inside of the recess can be smooth and may be in a straight line with the surface on the outside of the recess form. At the inner edge of the recess in the electrode surface, however, can also a step shown at 11 may be arranged. This stage helps with that inward movement of the pipe edge and the edge outward in direct the annular recess su. The step can be formed continuously but as shown it consists of the ends of the radially arranged strips 12 on the electrode surface, which is on the outer surface of the end piece at Welding create corresponding decorative depressions.
Fig. 2 zeigt den unter Verwendung der oben beschriebenen Vorrichtung hergestellten fertigen Behälter. Man erkennt, daß die äußere Oberfläche des Endstückes 2 eine ringförmige Rippe, die durch die nach außen gebogene außenkante 10 des rohrförmigen Hauptstückes 3 gebildet wird und innerhalb dieser Rippe eine Anzahl von radialen Vertiefungen und Leisten 13, die siob iur Basis der Auslaßdüse erstrecken, aufweist. Fig. 2 shows the using the device described above manufactured finished container. It can be seen that the outer surface of the end piece 2 an annular rib formed by the outwardly curved outer edge 10 of the tubular Main piece 3 is formed and within this rib a number of radial Depressions and ridges 13 which extend to the base of the outlet nozzle.
