Abstract

The plastic canister has a coaxial support ring in the pouring spout for a vent pipe, integral with the ring and of plastic and extending from it inside the canister. The ring has one or more ribs parallel to the axis of the spout and fitting in grooves in the latter, to prevent the ring turning in the spout. Hocked teeth on the ribs engage in the spout to prevent axial movement, and the spout is enclosed in a reinforcing sleeve to prevent it expanding. The design allows the canister to be produced by the blowing process while accommodating an injection-moulded cap.

Description

Die Erfindung betrifft einen Kanister aus Kunststoff mit einem koaxial im Auslaufstutzen angeordneten Tragring für ein Belüftungsrohr, das sich von dem Tragring ausgehend in das Innere des Kanisters erstreckt und mit dem Tragring einen einstUckigen Kunststoffkörper bildet.The invention relates to a canister made of plastic with a coaxially arranged in the outlet nozzle Support ring for a ventilation pipe, which extends from the support ring into the interior of the canister and forms a one-piece plastic body with the support ring.

Durch die DE-GMS 6752170 ist ein Kanister der eingangs genannten Art bekanntgeworden. Diese Vorrichtung hat u. a. folgende Nachteile:DE-GMS 6752170 makes a canister the initially mentioned type became known. This device has, inter alia. the following disadvantages:

a) Der Tragring kann beim Verdrehen der Schraubkappe rotatorisch mitgenommen werden. Damit verdreht sich das Belüftungsrohr. Wenn das behälterseitige Ende des Enitlüftungsrohrs nicht mehr in die richtige Richtung ragt, arbeitet die Entlüftung entweder nicht mehr zufriedenstellend oder gar nicht.a) The support ring can be rotated when turning the screw cap. This causes the ventilation pipe to twist. If the end of the ventilation pipe on the container side no longer protrudes in the right direction, the vent either no longer works satisfactorily or not.

b) Der Auslaufstutzen ist aus geblasenem Kunststoff und damit relativ weich im Verhältnis zur Schraubkappe, die man aus gespritztem Material herstellt und die deshalb wegen der im Spritzgußverfahren verwendeten hohen Drücke selbst bei gleichem Material wesentlich härter ist. Die weichen Zähne des Auslaufstutzens werden daher bei der viele Jahre dauernden Benutzung abgerieben, werden funktionsunfähig und der Kanister wird damit undicht.b) The outlet nozzle is made of blown plastic and is therefore relatively soft in relation to the Screw cap, which is made from injection-molded material and therefore because of the injection molding process The high pressures used are much harder even with the same material. the The soft teeth of the outlet spout are therefore rubbed off over many years of use, will become inoperable and the canister will leak.

c) Auch ohne Abrieb kriecht die Vorspannung der Schließkraft im Laufe der Zeit gegen null, weil zumindest der weiche Kunststoff nicht dauerstandfest ist. Auch hierdurch können Undichtigkeiten auftreten.c) Even without abrasion, the preload of the clamping force creeps towards zero over time, because at least the soft plastic is not durable. This can also cause leaks appear.

d) Das Material des Ausgußstutzens muß zur Erhöhung der Festigkeit dick gemacht werden. Dies steht dem Bestreben entgegen, möglichst gleich dicke Wandstärken zu erzielen. Außerdem ist es im Blasverfahren gerade beim Ausgußstutzen schwierig, dort Materialansammlungen vorzusehen. d) The material of the pouring spout must be made thick to increase strength. this stands in the way of efforts to achieve wall thicknesses that are as equally thick as possible. Besides, it is In the blow molding process, especially with the pouring spout, it is difficult to provide accumulations of material there.

e) Ein solcher Verschluß würde die BAM- und NEN-Prüfung nicht überstehen, da der Ausgußstutzen beim Fall des vollen Kanisters auf die Schraubkappe ausweichen würde. Es würde dann Kraftstoff austreten.
Durch die US-PS 2 800 241 ist ein Einsatz bekanntgeworden, der in den Hals einer Flasche geschoben werden kann. Der Einsatz hat Dichtlippen, die so elastisch sind, daß sie sich beim Einschieben umlegen können. Um die Flasche wieder zu befüllen, muß man den Einsatz herausziehen und ihn dann später wieder hineinschieben. Diese Handhabung ist bei Kanistern nicht möglich. Außerdem kriecht auch bei diesen Dichtlippen z. B. unter Einfluß von Wärme und/oder Treibstoff und/oder Alter der Spannungswert gegen null.e) Such a closure would not withstand the BAM and NEN tests, as the pouring spout would move to the screw cap if the canister fell full. Fuel would then leak out.
US Pat. No. 2,800,241 discloses an insert which can be pushed into the neck of a bottle. The insert has sealing lips that are so elastic that they can fold over when pushed in. To refill the bottle, you have to pull out the insert and then push it back in later. This handling is not possible with canisters. In addition, creeps even with these sealing lips z. B. under the influence of heat and / or fuel and / or age, the voltage value approaches zero.

Aufgabe der Erfindung ist es, den Auslaufstutzenbereich eines Kanisters so zu gestalten, daß er zwar einerseits die Herstellung des Kanisterkorpus im Blasverfahren gestattet, andererseits aber den zivilen und militärischen Anforderungen an Dauerstandfestigkeit, Dichtigkeit und Funktionsfähigkeit nach Fallwürfen usw. entspricht.The object of the invention is to design the spout area of a canister so that it on the one hand, the manufacture of the canister body in the blow molding process is permitted, on the other hand, the civilian and military requirements for fatigue strength, tightness and functionality Drop throws, etc. corresponds.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Tragring mindestens eine in eine Nut des Auslauf Stutzens eingepaßte, zu dessen Achse parallele Leiste aufweist, die den Tragring gegen ein Verdrehen gegenüber dem Auslaufstutzen sichert, und daß der Tragring durch an der Leiste angeordnete, widerhakenartige Zähne gegen axiale Verschiebung gesichert ist, welche Zähne in den Auslaufstutzen eingreifen, wobei eine den Auslaufstutzen gegen Aufweitung schützende, diesen umfassende Verstärkungshülse vorgesehen ist.According to the invention, this object is achieved in that the support ring is at least one in a groove of the outlet nozzle fitted, having a bar parallel to its axis, which prevents the support ring from rotating with respect to the outlet nozzle, and that the support ring is secured by means of barb-like teeth are secured against axial displacement, which teeth engage in the outlet nozzle, wherein a reinforcing sleeve which protects the outlet connection against expansion and surrounds it is provided.

Die Erfindung ermöglicht es, durch die den Stutzen umfassende Verstärkungshülse, daß der Stutzen extrem dünnwandig sein kann, ohne daß der Stutzen der Spannkraft des Tragringes ausweicht.The invention makes it possible, through the reinforcing sleeve comprising the connecting piece, that the connecting piece is extremely can be thin-walled without the nozzle giving way to the clamping force of the support ring.

Die Zeichnung zeigt ein Ausführungsbeispiel. Die Fig. 1 stellt es in einem Vertikalschnitt und die Fig. 2 in seinem Horizontalschnitt (Schnitt C-D) dar.The drawing shows an embodiment. Fig. 1 shows it in a vertical section and Fig. 2 in its horizontal section (section CD) .

Der Auslaufstutzen Sb des Kanisters ist ein einstückiger Ansatz am Kanisterkörper Sa. Er ist von der Verstärkungshülse la umfaßt, welche die Gabel Ib und die Bügel 2c eines Hakenschlosses 3 für den Deckel 4 trägt. Der Tragring Ib des Belüftungsrohres 1 α ist mit vier achparallelen Leisten Ic besetzt, welche in Nuten des Auslaufstutzens Sb eingepaßt sind. Widerhaken Id sichern den Tragring Ib axial, so daß er sich im in dem Auslaufstutzen Sb eingedrückten Ruhezustand nicht mehr bewegen kann. Er kann wcder sich verdrehen noch sich verschiebend wandern. Das Belüftungsrohr Ια, der Tragring Ib und die Leisten Ic sind Teile eines Körpers, der miterfindungsgemäß den Stutzen Sb gegen ein Zusammendrücken unter dem Zwang der Hülse la versteift.The outlet connection Sb of the canister is a one-piece extension on the canister body Sa. It is encompassed by the reinforcing sleeve la , which carries the fork Ib and the bracket 2c of a hook lock 3 for the cover 4. The support ring Ib of the ventilation pipe 1 α is occupied by four axially parallel strips Ic, which are fitted into grooves of the outlet connection Sb. Barbs Id secure the support ring Ib axially, so that it can no longer move in the rest state pressed into the outlet nozzle Sb. It can wander, twisting or shifting. The ventilation pipe Ια, the support ring Ib and the strips Ic are parts of a body which, according to the invention, stiffens the nozzle Sb against compression under the constraint of the sleeve la .

Der Abdichtring 6 besteht aus Gummi oder dergleichen. The sealing ring 6 is made of rubber or the like.
