Description
In der deutschen Patentanmeldung 1 120 124 wird zwar ein Verfahren zur Herstellung von größtenteils aus Kunststoff bestehenden, vorzugsweise mehrfarbigen Plomben, Siegeln, Abzeichen oder dergleichen durch Spritzgießen beschrieben, jedoch besteht dieses Verfahren lediglich darin, dass eine zur Kennzeichnung dienende Scheibe in einer Spritzgußform mit einem wulstförmigen Rand umspritzt wird. Zweckmäßiger erscheinen Plomben oder Nieten aus Kunststoff, deren beide Teile in der Weise hergestellt sind, daß ein Zapfen mit einer Verstärkung am Ende in eine entsprechende Aussparung des zweiten Teiles einschnappt.In the German patent application 1 120 124 a method for the production of mostly plastic, preferably multicolored Seals, seals, badges or the like described by injection molding, however This method consists only in the fact that a disc which is used for identification is encapsulated in an injection mold with a bead-shaped edge. More expedient appear seals or rivets made of plastic, both parts of which are made in the manner are that a pin with a reinforcement at the end in a corresponding recess of the second part snaps into place.
Die beiden Teile der Plombe können durch einen mehr oder weniger langen Verbindungssteg beliebigen Profils (rund, oval, rechteckig, flach) zusammenhängen, wodurch der sonst bei Plomben einliegende Draht usw. ersetzt wird. Figur 1 zeigt die beiden Teile einer solchen Plombe in Auf sich" mit einer Verbindungslasche.The two parts of the seal can be more or less long Connecting web of any profile (round, oval, rectangular, flat), which replaces the wire, etc. that is otherwise inserted in the seals. figure 1 shows the two parts of such a seal in "on" with a connecting strap.
, Figur 2 gibt die beiden Teile von der Seite wieder. Die Hinterschneidung
an der Verstärkung des Zapfens ist so steil, daß eine
Die Verbindung kann ohne Plombierzange vorgenommen werden.The connection can be made without sealing pliers.
Solche Formkörper können leicht im Spritzgußverfahren hergestellt werden. Die Hinterschneidungen sind so gering, dass eine Entformung in warmem Zustand ohne komplizierte Form möglich ist ; andererseits aber so steil, dass nach dem Erkalten die beiden Teile der Plombe oder Niete nicht mehr gelöst werden können. Besonders geeignet für diesen Zweck ist ein relativ elastischer Kunststoff, wie z. B. Hartpolyäthylen oder besonders isotaktisches Polypropylen.Such moldings can easily be produced by injection molding will. The undercuts are so small that they can be removed from the mold in a warm state is possible without a complicated shape; but on the other hand so steep that after cooling down the two parts of the seal or rivet can no longer be loosened. Particularly suitable for this purpose is a relatively elastic plastic, such as. B. Rigid polyethylene or especially isotactic polypropylene.
