Description
Vorrichtung zum VersohlieBen für Stutzen von Behältern. Device for sealing the necks of containers.
Die Erfindung betrifft eine Vorrichtung zum Verschließen fUr Stutzen von Behältern z. B. Kanistern, aus Kunstharz mittels Kappe. Eines ihrer wesentlichen Merkmale ist dadurch geke zeichnet, da# anstelle der üblichen Klapp- oder Schraubverschlüsse ein steckrenkverschlu# vorgesehen ist, wobei die Renkelemente aus mehreren Gewindezahngruppen bestehen, so daß zuerst die Kappe axial aufgesteckt und dann renkend gedreht wird. The invention relates to a device for closing off nozzles of containers e.g. B. Canisters made of synthetic resin by means of a cap. One of their essentials Characteristics is characterized by the fact that # instead of the usual snap or screw caps a steckerenkverschlu # is provided, wherein the bayonet elements consist of several groups of threaded teeth exist, so that first the cap is attached axially and then rotated renkend.
Damit wird die Aufgabe vorteilbringend gelöst, Stutzen rasch Verschließen und sie dazuhin mit soviel Gewindeelementen versehen zu können, da# klaglos gro#e Abdichtkräfte erzeugbar sind.This advantageously solves the problem of closing the neck quickly and to be able to provide them with so many threaded elements that they are large without complaint Sealing forces can be generated.
Dabei ist Selbsthemmung mit Sicherheit erreichbar, womit in folgedessen sämtliche Vorteile der Klappdeckelverschlü#e tEr Drehklappenversohlüssenachgeholtwordensind,ohneeinen der Vorteile der bekannten reinen Drehkappenverschlu#vorrichtungen aufgeben zu müssen.Self-locking can be achieved with certainty, and consequently All the advantages of the hinged lid locks on the rotary flap locks have been made up for, without one having to give up the advantages of the known pure twist-top closure devices.
Bei Vorrichtungen mit Abdichtring zwischen Kappe und Stutzenstirnfläche ist es gunstig, wenn in weiterer Ausgestaltung des Erfindungestrebens ein Zwischenring als Halter eines von Ausgu#-stutzen des Behälters in den Behälterhauptraum zurückführenden Rohres zum Belüften des Behälters beim Entleeren angeordnet ist, eine Bauart, die durch die Maßnahme verbesserbar ist, eine die Abdichtung vollziehende, z. B. den Abdichtring zentrierende, vorzugsweise festhaltende Einlageplatte für die Kappe zwischen diese und den Stutzen einzuschalten.For devices with a sealing ring between the cap and the nozzle face it is advantageous if an intermediate ring is sought in a further embodiment of the invention as a holder of one of the outlet spouts of the container leading back into the main container space Tube is arranged for venting the container during emptying, a type that can be improved by the measure, a sealing accomplishing, z. B. the Sealing ring centering, preferably retaining insert plate for the cap to be switched between this and the nozzle.
Die Zeichnung zeigt Ausführungsbeispiele. The drawing shows exemplary embodiments.
Fig 1 stellt eine Vorrichtung in einem Vertikalschnitt dar, von der die Fig 2 die Kappe samt Einlageplatte und Abdichtring wiedergibt, während die Fig 3 die Draufsicht auf den Stutzen eines Kanisters zeigt. Die Fig 4 veranschaulicht den Aufriß der Kappe öffnungsseittig und die Fig 5 eine Variante der Halterung der Einlageplatte in einem Axialschnitt. Die: Fig. 6 seigt die Abwicklung von drei gleichseitig in Eingriff gehenden Gewindezahngruppen, bezogen auf den Umfang 2 rp (r = Raius und P= pi). Fig. 1 shows a device in a vertical section, of which Fig. 2 shows the cap including the insert plate and sealing ring, while Fig Figure 3 shows the top view of the neck of a canister. Figure 4 illustrates the elevation of the cap on the opening side and FIG. 5 shows a variant of the holder of the Insert plate in an axial section. The: Fig. 6 shows the development of three equilateral meshing thread tooth groups, based on the circumference 2 rp (r = Raius and P = pi).
Das Hauptteil der Vorrichtung zum Verschlie#en des Stutzens 1 des Kanisters K aus einem Thermoplast ist die Kappe 3 in Verbindung -mitdenRenkelementen-inGestaltderdreiGewindezahngruppen, Db. Zwischen Kappe 3 und Stutzenstirnfläche ist der Rand 2b eines Zwischenringes 2 als Halte eines vom Ausgu#stutzen 1a des Kanisters K bzw. Behälters in den Behälterhauptraum zurückführenden Rohres 2a eingespannt. Dieses Rohr 2a des Ringes 2 dient zum Belüften des Behälters beim Entleeren. Die Abdichtung zwischen Kappe 3 und Stutzen 1 bewirkt die den Abdichtring 5 @mittels zentrierende, mittels der Wulst 4a auch festhaltende Einlageplat-te 4, so daN der Abdiohtring 5 in der Einlageplatte 4 durch die Wulst 4c axial gesichert ist, wenn die Kappe vom Stutzen abgenommen wird. Die Kappe 3 liegt mithin tber den Rand 4 der Einlegeplatte 4, über den Abdichtring 5 und tuber den Flansch 2b des Zwischenringes 2 stirnflächig mittelbar auf dem Stutzen 1 auf. The main part of the device for closing the nozzle 1 of the Canister K made of a thermoplastic is the cap 3 in connection with the steering elements in the form of the three groups of threaded teeth, Db. The edge 2b of an intermediate ring is between the cap 3 and the nozzle end face 2 to hold one of the pouring spout 1a of the canister K or container in the main container space returning pipe 2a clamped. This tube 2a of the ring 2 is used for ventilation of the container when emptying. The seal between cap 3 and nozzle 1 causes the one that centers the sealing ring 5 by means of the bead 4a and also holds it in place Insert plate 4, so that the dioh ring 5 in the insert plate 4 through the bead 4c is axially secured when the cap is removed from the nozzle. The cap 3 is therefore t over the edge 4 of the insert plate 4, over the sealing ring 5 and tuber the flange 2b of the intermediate ring 2 on the end face indirectly on the connecting piece 1.
Die Gewindezahngruppen 1a, 3b sind vorzugsweise in der Art Teile von mehrgängigen Gewinden, da# die Zahl der Gewindezahngruppen der Gangzahl des Gewindes entspricht. Die drei Gewindegruppen jedes der beiden Renkelemente sind deshalb beim Ausfuhrungsbeispiel im Sinne eines dreigängigen Gewindes angelegt, was jedoch nicht unbedingt sein müßte.The thread tooth groups 1a, 3b are preferably in the manner of parts of multi-start threads, since # the number of thread tooth groups of the number of threads of the thread is equivalent to. The three thread groups of each of the two bayonet elements are therefore with Exemplary embodiment created in the sense of a three-start thread, but this is not absolutely must be.
Nach Fig 1 ist die Einlageplatte 4. mittels eines Zentralbolzens in der Kappe 3, 3a zentriert und durch einen Druckknopf 6a axial gesichert. Bei der Variante der Fig 5 ist es umgekehrt. Der Zentralbolzen 4a der einlageplatte 4 ist in einen Druckknopf 6a eingeschnappt, der die Einlageplat. 4 in der Kappe 3 zentriert.According to Fig. 1, the insert plate is 4. by means of a central bolt in the cap 3, 3a centered and axially secured by a push button 6a. In the In the variant of FIG. 5, it is the other way round. The central bolt 4a of the insert plate 4 is snapped into a push button 6a, the insert plate. 4 centered in cap 3.
Der Axialringsteg 4c der Einlageplatte 4 zentriert diese gegenüber dem Zwischenring 2.The axial ring web 4c of the insert plate 4 centers this opposite the intermediate ring 2.
Nicht dargestellt sind Renküberdrehsicherungsansohläge, die ein Überdrehen der Kappe verhindern könnten, wenn eine anormal große Verdrehkraft an der Kappe angreifen sollte, In der Regel wirken jedoch im Notfall schon die Gewindezahngruppen als Uberdrehsicherungen, wenn man sie handwerklich geschickt dimensionier und anordnet.Not shown are Renk overturning protection soles that prevent overturning the cap if there is an abnormally large twisting force on the cap should attack, but as a rule, in an emergency, the groups of threaded teeth are already effective as overturn protection, if you dimension and arrange them skillfully by hand.
