Abstract

Container with rivetted-on parts of flexible material, e.g., cardboard or plastics, esp. with rivetted-on handle, is described. The container is designed as a carbon, drum or barrel and may be used for flowable material e.g., washing powder. The handle(s) is fixed with rivets having an ultrasonically shaped rivet head. The rivet is made of a thermoplastics pref. polyethylene or a polyamide. The rivets are fixed to the container by shaping the rivet head with a tool vibrated by ultrasonic frequencies. When a rivet has been fitted the tool is held in place about the shaped rivet head to allow it to cool and set. The plastics rivets are cheaper than prior-art metal rivets. There is no risk of a user of the container injuring himself or herself on sharp edges of the rivets. The rivets cannot rust.

Description

"Behälter mit aneinandergenieteten Teilen" "Container with parts riveted together"

Die Erfindung betrifft einen Behälter mit cneinandergenieteten Teilen aus flexiblem Material, wie Pappe oder Kunststoff, insbesondere mit angenietetem Tragegriff, vorzugeiz als Paket, Schaclltel oder Trommel bzw. aaß ausgebildeter Behälter zur Aufnahme von Schüttgut, zum Beispiel von pulverförmigem Waschmittel. Die Erfindung betrifft ferner ein Verfahren zum Verbinden von Teilen eines vorgenannten Behälters durch Niete.The invention relates to a container with parts riveted together made of flexible material such as cardboard or plastic, especially with riveted Carrying handle, vorzueiz as a package, shackle or drum or ate trained Container for holding bulk goods, for example powder detergent. The invention also relates to a method for joining parts of the aforesaid Container by rivet.

Bei einer Vielzahl derartiger Behälter werden zum Verbinden der Einzelteile Blechniete benutzt. Das gilt vor allem für solche Teile, die bei Gebrauch des Behälters relativ zueinander beweglich sein sollen. Beispielsweise handelt es sich dabei um Tragegriffe, die hin- und herschwenkbar sein sollen. Insbesondere in der Waschmittelindustrie werden Trommeln, Fässer oder Großpakete verwendet, an denen ein Tragegriff durch Niete befestigt ist. Diese Tragegriffe stehen beim Tragen oberhalb des Deckels und werden beim Entleeren des Behälters zur Seite geschwenkt.In a large number of such containers are used to connect the individual parts Sheet metal rivets used. This is especially true for those parts that are in use when the container should be movable relative to each other. For example, it is Carrying handles that should be pivotable back and forth. Especially in the detergent industry drums, barrels or large packages are used with a handle through them Rivet is attached. These handles are above the lid and when carried are swiveled to the side when emptying the container.

Der Nachteil des Blechniets besteht im Zusammenhang mit den vorgenannten Behälterarten nicht nur in dem relativ großen Aufwand an teuerem Material sondern auch darin, daß sich der Verwender an den Nietköpfen verletzen kann. Da Blechniete zum Rostbefall neigen, besteht immer die Gefahr, daß mit den Blechnieten in Berührung kommende Stoffe Rostflecken erhalten, insbesondere können versehentlich in den Behälter gelangende Blechniete im Behälterinhalt oder an mit letzterem in Berührung kommenden Gegenständen bzw. Stoffen Rostflecken verursachen.The disadvantage of the sheet metal rivet is related to the aforementioned Types of containers not only in the relatively large amount of expensive material but also in the fact that the user can injure himself on the rivet heads. There sheet metal rivets tend to rust, there is always the risk that with the sheet metal rivets Fabrics that come into contact receive rust stains, especially accidentally Sheet metal rivets that get into the container in the contents of the container or on with the latter in Objects or materials coming into contact with it cause rust stains.

Es ist daher versucht worden, anstelle der Blechniete Kunststoffniete zu verwenden. Solche Kunststoffniete lassen sich jedoch mit vertretbarem Aufwand nicht - etwa wie Blechniete -einfach durch Pressen herstellen. Auch Versuche der Anformung des Schließ- oder Nietkopfes durch direkte Erwärmung mit Hilfe eines elektrisch beheizten Formwerkzeugs ergaben keine definierte, reproduzierbare Verformung des Niets. Außerdem ist diese Art der direkten Erwärmung des Niet aufwendig, weil der Nietschaft zunächst mit einem Formwerkzeug bis über die Schmelztemperatur des Kunststoffs erwärmt werden und dann mit einem kalten anderen Werkzeug der Schließkopf geformt werden muß.Attempts have therefore been made to use plastic rivets instead of sheet metal rivets to use. However, such plastic rivets can be done with reasonable effort not - like sheet metal rivets - simply produce by pressing. Also attempts of Forming of the closing or rivet head by direct heating with the help of an electric heated mold did not result in a defined, reproducible deformation of the Rivets. In addition, this type of direct heating of the rivet is expensive because of the First of all, use a molding tool to raise the rivet shank to above the melting temperature of the plastic are heated and then the closing head is formed with another cold tool must become.

Der Erfindung liegt die Aufgabe zugrunde, einen Behälter mit an einandergenieteten Teilen der eingangs genannten Gattung zu schaffen, bei dem die vorerwähnten Nachteile nicht auftreten und bei dem Kunststoffniete zum Verbinden der Einzelteile vorgesehen sind. Es soll ferner ein Verfahren zum Vernieten von Teilen eines solchen Behälters geschaffen werden, durch das bei geringem Aufwand Kunststoffniete mit reproduzierbarer, definierter Form des Nietkopfes in der#Packmaschine herstellbar sind.The invention has for its object to provide a container with riveted to each other To create parts of the type mentioned, in which the aforementioned disadvantages do not occur and provided with the plastic rivet for connecting the individual parts are. It is also intended to provide a method for riveting parts of such a container created, through which plastic rivets with reproducible, Defined shape of the rivet head can be produced in the # packing machine.

Für den Behälter besteht die Lösung darin, daß ein Niet mit durch Ultraschall geformtem Nietkopf aus thermoplastischem Kunststoff vorgesehen ist. Die erfindungsgemäßen Niete können insbesondere aus Polyäthylen oder Polyamid bestehen.For the container, the solution is that a rivet through Ultrasonically molded thermoplastic rivet head is provided. The rivets according to the invention can in particular consist of polyethylene or polyamide.

Bei dem Verfahren zum Verbinden von Teilen eines Behälters durch Niete besteht die Lösung gemäß weiterer Erfindung darin, daß ein aus thermoplastischem Kunststoff bestehender Niet verwendet wird, daß das Nieten bzw. das Ausformen des Nietkopfes am Behälter mit einem mit Ultraschallfrequenz mechanisch erregtem Nietstempel bzw. Werkzeug erfolgt und daß das Werkzeug nach Entregung während einer Nachhaltezeit, in der es den Nietkopf weiterhin umschließt, zum Abkühlen und Erhärten des Nietkopfes verwendet wird.In the method of joining parts of a container by riveting is the solution according to a further invention that a thermoplastic Plastic existing rivet used that the riveting resp. the forming of the rivet head on the container with an ultrasonic frequency mechanically excited riveting punch or tool takes place and that the tool after de-excitation during a hold-up time, in which it continues to surround the rivet head, for cooling and Hardening of the rivet head is used.

Gemäß weiterer Erfindung kann ein bereits vorgeformter -zum Beispiel mit einem Vielfach-Werkzeug gespritzter - Niet verwendet werden, oder es kann als Ausgangsmaterial zum Nieten ein vorzugsweise zylindrischer Stift vorgesehen sein.According to a further invention, an already preformed -for example Can be used as an injection-molded rivet with a multiple tool, or it can be used as a Starting material for riveting a preferably cylindrical pin can be provided.

Im ersteren Falle wird in der Packmaschine ein einziger Nietkopf angeformt, im anderen Falle sind beim Nieten aus beiden Enden des Stiftes Nietköpfe zu bilden. Zwar erfordert das Formen der beiden Nietköpfe an dem Stift bzw. Nietschaft einen etwas größeren Aufwand zu der Nieteinrichtung als im ersteren Falle, bei der Massenproduktion kann es aber entscheidend sein, daß das Ausgangsmaterial bei dem einfachen Stift natürlich bilhgwist als bei dem mit Setzkopf vorgeformten Niet.In the former case, a single rivet head is formed in the packing machine, in the other case, rivet heads are to be formed from both ends of the pin when riveting. It is true that the shaping of the two rivet heads on the pin or rivet shank requires one somewhat greater effort for the riveting device than in the first case, in mass production but it can be decisive that the starting material in the simple pen naturally bilhgwist than with the preformed rivet with a setting head.

Durch die Erfindung ist ein Niet für einen Behälter der eingangs genannten Gattung und ein Verfahren zum Herstellen eines solchen Niets aus Kunststoff, dessen jeweiliger Kopf in der Packmaschine mit ein und demselben Werkzeug in einem Arbeitsgang bildbar ist, geschaffen worden. Da das jeweilige Werkzeug selbst bei Erregung durch Ultraschallfrequenz nicht wesentlich erwärmt wird, kann es nämlich gleichzeitig zum Ausformen des Nietkopfes benutzt werden. Der neue, aus Kunststoff bestehende Niet kann Rostflecken nicht verursachen. Der gegegenüber einem Blechniet weiche Kunststoffniet stellt keine nennenswerte Quelle für Verletzungen dar.The invention provides a rivet for a container of the type mentioned at the beginning Genus and a method for producing such a rivet made of plastic, the each head in the packing machine with one and the same tool in one operation is formable, has been created. Because the respective tool by itself when energized Ultrasonic frequency is not heated significantly, it can namely at the same time can be used to shape the rivet head. The new one made of plastic The rivet cannot cause rust stains. The soft opposite a sheet metal rivet Plastic rivets are not a significant source of injury.

Die Materialkosten für einen Kunststoffniet liegen erheblich unter denjenigen für einen Blechniet. Das gilt sowohl bei Verwendung von Nieten mit bereits angeformtem Setzkopf als auch dann, wenn als Ausgangsmaterial ein Stift benutzt wird, an dessen beiden Enden Nietköpfe in der Packmaschine zu bilden sind. Schließlich hat sich unerwartet ergeben, daß der Kunststoffniet gegenüber dem Blechniet eine großere ere Ausreißfestigkeit hat; letzteres bringt vor allem bei großen Behältern, Paketen oder Fässern erhebliche Vorteile.The material costs for a plastic rivet are considerably lower the one for a sheet metal rivet. This applies both to the use of rivets with already molded set head as well as when a pin is used as the starting material is, at both ends of which rivet heads are to be formed in the packing machine. In the end it turned out unexpectedly that the plastic rivet opposite the Sheet metal rivets have a greater pull-out strength; the latter mainly teaches large containers, packages or barrels.

Im folgenden werden weitere Einzelheiten zu dem erfindungagemäßen Behälter und dem erfindungsgemäßerl Verfahren zum Nieten teilweise anhand der beigefügten Zeichnung erläutert; es zeigen: Figur 1 einen Behälter mit angenietetem Tragegriff im Querschnitt, Figur 2 die fertige Nietverbindung und Figur 3 eine schematische Prinzipzeichnung einer Ultraschallnieteinrichtung.In the following, further details are given to the according to the invention Container and the inventive method for riveting partially based on the attached Drawing explained; They show: FIG. 1 a container with a riveted handle in cross section, FIG. 2 the finished riveted connection and FIG. 3 a schematic Principle drawing of an ultrasonic riveting device.

Beim erfindungsgemäßen Nieten mit Ultraschall erzeugt ein mit hochfrequenten (20 bis 100 kHz) mechanischen Schwingungen erregter Nietstemp#el an der Berührungsstelle mit dem Bunst stoff des Nietschafts Friktionswärme, die den Nietschaft zum Schmelzen bringt. In einem Ausführungsbeispiel beträgt die reine Nietzeit, das heißt die Einwirkung des Ultraschalls, ca. eine Sekunde. Nach Abschalten der Ultraschall-Erregung des Nietstempels läßt man diesen in einer Nach haltezeit von ca. drei Sekunden auf dem Niekopf ruhen, so daß der Niet stempel den Nietkopf formt und bis zum Erhärten abkühlt.When riveting with ultrasound according to the invention, a high frequency generated (20 to 100 kHz) mechanical vibrations of excited riveting dies at the point of contact with the plastic of the rivet shaft frictional heat that melts the rivet shaft brings. In one embodiment, the pure riveting time, that is, the action of the ultrasound, about one second. After switching off the ultrasonic excitation of the The riveting punch is left on the after holding time of approx. Three seconds Never rest the head so that the rivet punch forms the rivet head and cools down until it hardens.

In Figur 1 ist der Querschnitt einer aus Pappe oder Kunststoff bestehenden Trommel 1 dargestellt. Am oberen Ende der Trommel 1 ist ein Tragegriff 2 angenietet. Die Niete 3 bestehen aus Kunststoff, zum Beispiel Polyäthylen oder Polyamid, und weisen gemäß Figur 2 wenigstens einen Nietkopf 5 auf, der mit Hilfe eines mit Ultraschallfrequenz mechanisch erregten Nietstempels bzw. Werkzeugs geformt worden ist.In Figure 1 is the cross section of a cardboard or plastic Drum 1 shown. A handle 2 is riveted to the upper end of the drum 1. The rivets 3 are made of plastic, for example polyethylene or polyamide, and have according to Figure 2 at least one rivet head 5, which with the help of an ultrasonic frequency mechanically excited riveting punch or tool has been formed.

Eine Ultraschall-Nieteinrichtung zum Formen je eines Nietkopfes 5 aus den Enden eines Stoffes oder Nietschaftes 4 besteht gemäß Figur 3 aus einem Generator 6 und je einem Konverter 8 mit zugehörigem Werkzeug 9. Die Konverter 8 sind mit dem Generator 6 über Kabel 11 und 12 verbunden.An ultrasonic riveting device for forming one rivet head 5 each consists of the ends of a fabric or rivet shank 4 according to Figure 3 from one Generator 6 and one each Converter 8 with associated tool 9. The converters 8 are connected to the generator 6 via cables 11 and 12.

Zwischen den Generator 6 und die Konverter 8 kann ein elektronischer Schalter 7 gesetzt sein, derart, daß auf den Generator weitere (nicht gezeichnete) Konverter mit Werkzeugen schaltbar sind.Between the generator 6 and the converter 8 can be an electronic Switch 7 be set in such a way that further (not shown) on the generator Converters are switchable with tools.

Bei Anwendung der Werkzeuge 9 werden diese auf die Enden des durch die Wand der Trommel 1 und den Tragegriff 2 geschobenen Nietschaftes 4 aufgesetzt. Beim Ausformen der Nietköpfe 5 des Niets 3 werden zweckmäßig die Werkzeuge 9 zusammen mit den Konvertern 8 in Pfeilrichtung relativ zum Nietschaft 4 bewegt. Die Konverter 8 können dann beispielsweise in eine Art Schlittenführung 10 gesetzt sein.When using the tools 9 these are on the ends of the through the wall of the drum 1 and the handle 2 pushed rivet shaft 4 placed. When forming the rivet heads 5 of the rivet 3, the tools 9 are expediently together moved with the converters 8 in the direction of the arrow relative to the rivet shank 4.
