Abstract

The closure is intended for a container 1 made, in particular, of plastic and provided with a nozzle 2. The closure can be introduced into the container nozzle so as to be sealed off by means of a tube extension 6, fitted with sealing lips 7. The closure is to be anchored fixedly and non-displaceably in said container nozzle in such a way that the inner end of its tube extension does not extend over the root region of the container nozzle into the container. In order to secure the seating of the closure, an essentially U-shaped profiled ring 17 is pressed in such a way over a flange 5, bearing the tube extension and guided against the end face of the container nozzle, that its upper profile leg 18 rests firmly on the flange 5 and its lower profile leg firstly slides along a collar 3, which reinforces the removal nozzle, and then engages undetachably behind the rear boundary surface of the collar which is perpendicular to its axis. <IMAGE>

Description

Die Erfindung betrifft einen Kunststoffbehälter mit einem Verschluß für dessen als Behälterstutzen ausgebildete Entnahmeöffnung, bei dem der Verschluß mit einem Flansch eines Basisteils die Stirnfläche des Behälterstutzens übergreift und mit einem außen mit Dichtlamellen versehenen Rohransatz in den Behälterstutzen dichtend eingeführt ist, bei dem der Behälterstutzen außen mit einem ringförmigen Bund versehen ist und bei dem der Verschluß mittels eines Halteelementes auf dem Behälterstutzen gehalten ist, das sich auf dem Flansch des Verschlusses abstützt und mit einem äußeren Profilschenkel den Bund des Behälterstutzens der Entnahmeöffnung abgekehrt hintergreift.The invention relates to a plastic container with a closure for its removal opening designed as a container socket, in which the closure engages over the end face of the container socket with a flange of a base part and is sealingly inserted into the container socket with a pipe lug provided with sealing lamellae, in which the container socket is outside with is provided an annular collar and in which the closure is held by means of a holding element on the container neck, which is supported on the flange of the closure and engages behind the collar of the container neck of the removal opening with an outer profile leg.

Ein als Flasche ausgebildeter Behälter dieser Art ist durch die BE-A 661 591 bekannt. Dabei dichten die Dichtungslamellen zwischen dem Rohransatz des Verschlusses und der Innenwandung des Behälterstutzens ab. Der Verschluß ist aus Gründen einer ausreichenden Dichtwirkung dabei aus einem elastischen Kunststoff hergestellt. Das Halteelement ist als Sicherungsring ausgebildet, der hinter den Bund des Behälterstutzens einrastet. Der Sicherungsring stützt sich zum Teil auf dem Flansch des Verschlusses ab, so daß dieser in der Entnahmeöffnung des Behälterstutzens gehalten ist. Dabei überdeckt der Sicherungsring ein zusätzliches Verschlußteil, das die Durchgangsöffnung des Verschlusses abdeckt und das entfernt werden kann, wenn ein Teil des Sicherungsringes aufgezogen ist. Der Sicherungsring behält aber seine Funktion als Halteelement bei. Das Halteelement und der Verschluß in dieser Ausgestaltung vermögen aber keine großen Kräfte aus dem Behälterinneren abzufangen, so daß diese Art Verschluß und Sicherung nur für Flaschen mit kleinem Inhalt geeignet sind. Die Übertragung dieses bekannten Verschlusses auf größere Gebinde mit gefährlichem Inhalt scheitert daran, daß dieser Verschluß bei großem Innendruck, wie er z.B. beim Fallen des Behälters auftreten kann, nicht hält oder zumindest leckt.A container of this type designed as a bottle is known from BE-A 661 591. The sealing lamellas seal between the tube extension of the closure and the inner wall of the container neck. For reasons of a sufficient sealing effect, the closure is made of an elastic plastic. The holding element is designed as a locking ring that snaps behind the collar of the container neck. The retaining ring is partially supported on the flange of the Closure so that it is held in the removal opening of the container neck. The locking ring covers an additional closure part which covers the through opening of the closure and which can be removed when part of the locking ring is pulled open. The retaining ring, however, retains its function as a holding element. The holding element and the closure in this embodiment, however, are unable to absorb large forces from the interior of the container, so that this type of closure and securing are only suitable for bottles with a small content. The transfer of this known closure to larger containers with dangerous contents fails because this closure does not hold or at least leak when the internal pressure is high, as can occur, for example, when the container falls.

Aus der US-A 4 111 331 ist ein Verschluß für einen Behälter bekannt, dessen Behälterstutzen auf der Außenseite sägezahnartig verzahnt ist und auf den eine mit entsprechender Gegenverzahnung versehene Verschlußkappe aufgerastet wird. Die Verschlußkappe rastet mit einer Wulstaufnahme zusätzlich auf einen umlaufenden Wulst des Behälterstutzens und ein Sicherungsring umschließt die Wulstaufnahme der Verschlußkappe. Auf diese Weise wird die Verschlußkappe zustäzlich auf dem Behälterstutzen gesichert. Die Verschlußkappe stützt sich selbst mit einem Flansch über eine Dichtungsmanschette auf der Stirnfläche des Behälterstutzens ab, wobei die Abdichtung auf einen kleinen Ringspalt begrenzt ist. Da die Verschlußkappe eine gewisse Eigenelastizität aufweist und bei auftretendem Innendruck die Dichtungsstelle in Richtung zum Öffnen des Verschlusses beaufschlagt wird, wird im Bereich des Verschlusses eine eindeutige Lecksicherung des Behälters erreicht, insbesondere für große Behälter.From US-A 4 111 331 a closure for a container is known, the container neck of which is serrated on the outside and onto which a closure cap provided with corresponding counter-toothing is snapped on. The closure cap also snaps onto a circumferential bulge of the container neck with a bead receptacle, and a locking ring surrounds the bead receptacle of the closure cap. In this way, the cap is additionally secured on the container neck. The cap is supported by a flange on a sealing collar on the end face of the container neck, the sealing being limited to a small annular gap. Since the closure cap has a certain intrinsic elasticity and, when internal pressure occurs, the sealing point is acted upon in the direction of opening the closure, a clear leakage protection of the container is achieved in the region of the closure, in particular for large containers.

Es ist Aufgabe der Erfindung, für einen Kunststoffbehälter der eingangs erwähnten Art einen Verschluß zu schaffen, der ohne zusätzliche Dichtungsmanschette den Behälterstutzen absolut lecksicher verschließt und auch beim Auftreten von hohem Druck im Behälter nicht leckt oder gar unbeabsichtigt öffnet.It is an object of the invention to provide a closure for a plastic container of the type mentioned at the outset which closes the container neck absolutely leak-proof without an additional sealing sleeve and does not leak or even accidentally open even when high pressure occurs in the container.

Diese Aufgabe wird nach der Erfindung dadurch erreicht, daß das Halteelement als im Querschnitt L-förmig profilierter Ring aus hartem Kunststoff oder Metall ausgebildet ist, der mit einem achsnormal verlaufenden Profilschenkel den Flansch vollständig überdeckt, daß der Bund des Behälterstutzens der Entnahmeöffnung abgekehrt eine achsnormale Bundfläche aufweist, und daß der achsparallele Profilschenkel des Ringes auf seiner Innenseite sägezahnartig profiliert ist, wobei eine dem achsnormalen Profilschenkel abgekehrte flache Flanke das Aufsetzen des Ringes auf den in den Behälterstutzen eingeführten Verschluß erleichtert und eine achsnormale Flanke beim Aufsetzen des Ringes hinter die Bundfläche des Bundes des Behälterstutzens einrastet.This object is achieved according to the invention in that the holding element is designed as a cross-sectionally L-shaped ring made of hard plastic or metal, which completely covers the flange with an axially normal profile leg, that the collar of the container neck of the removal opening is turned away from an axially normal collar surface has, and that the axially parallel profile leg of the ring is sawtooth-shaped on its inside, a flat flank facing away from the axially normal profile leg facilitates the placement of the ring on the closure inserted into the container neck and an axially normal flank when the ring is placed behind the collar surface of the federal government Container socket snaps into place.

Bei dieser Ausgestaltung überdeckt das als L-förmiger Ring ausgebildete Halteelement den Flansch des Verschlusses und damit die Stirnseite des Behälterstutzens vollständig, so daß in Verbindung mit der Rastverbindung zwischen dem Ring und dem Behälterstutzen der Flansch des Verschlusses vollständig zwischen der Stirnfläche des Behälterstutzens und dem achsnormalen Profilschenkel des Ringes verspannt wird. Die eindeutige Abdichtung der Entnahmeöffnung übernehmen die am Rohransatz angeformten Dichtungslamellen des aus elastischem Kunststoff hergestellten Verschlusses und dies auch bei hohem Druck im Kunststoffbehälter, wenn dieser z.B. durch Aufprall verformt wird. Es ist keine getrennte Dichtungsmanschette erforderlich und die Sicherung des Verschlusses ist wesentlich verbessert, da der Innendruck voll vom achsnormalen Profilschenkel des Ringes abgefangen wird, ohne das Lösen der Rastverbindung zwischen dem Ring und dem Behälterstutzen befürchten zu müssen. Der aus hartem Kunststoff oder Metall bestehende Ring erfordert wohl eine erhöhte Kraft zum Aufsetzen auf dem Behälterstutzen, bringt aber eine wesentliche Erhöhung der Verschluß- und Lecksicherheit.In this embodiment, the L-shaped ring holding element completely covers the flange of the closure and thus the end face of the container neck, so that in connection with the latching connection between the ring and the container neck the flange of the closure completely between the end face of the container neck and the axially normal Profile leg of the ring is clamped. The sealing lamella of the closure, which is made of elastic plastic and is molded onto the tube attachment, provides the clear sealing of the removal opening, even at high pressure in the plastic container, if this is deformed, for example, by impact. There is no need for a separate sealing sleeve and the securing of the closure is significantly improved, since the internal pressure is fully absorbed by the axially normal profile leg of the ring, without having to fear that the snap connection between the ring and the container neck will be released. The ring made of hard plastic or metal probably requires an increased force to be placed on the container neck, but brings a significant increase in the security against locking and leakage.

Zweckmäßige und vorteilhafte Weiterbildungen sind in den Unteransprüchen gekennzeichnet.Appropriate and advantageous further developments are characterized in the subclaims.

Im einzelnen sind die Merkmale der Erfindung anhand der folgenden Beschreibung von Ausführungsbeispielen in Verbindung mit diese darstellenden Zeichnungen erläutert. Es zeigen:

Figur 2
in gleichartiger Darstellung einen abgewandelten Verschluß.
The features of the invention are explained in detail on the basis of the following description of exemplary embodiments in conjunction with these drawings. Show it:
Figure 1
the top part of a canister with a closure closing it, and
Figure 2
in a similar representation a modified closure.

In der Figur ist abgebrochen ein Bereich eines als Hohlkörper erblasenen Kunststoffbehälters 1 in Form eines Kanisters dargestellt, dessen Entnahmeöffnung durch einen am freien Ende durch einen Bund 3 verstärkten Stutzen 2 des Behälters umgrenzt ist. In den Behälterstutzen 2 ist ein Basisteil 4 eines Verschlusses so eingepreßt, daß dessen Flansch 5 fest auf der Stirnfläche des Behälterstutzens 2 aufliegt und der an den Flansch 5 anschließende Rohransatz 6 in den Behälterstutzen 2, durch seine elastischen Dichtlamellen abgedichtet, eingreift. Da hinter der Entnahmeöffnung keine Verankerung erfolgt, ist es auch nicht erforderlich, daß der Rohransatz 6 nach innen über den Behälterstutzen 2 vorsteht; er kann mit gleicher Länge oder kürzer ausgeführt sein als der Behälterstutzen. An den Flansch schließt sich weiterhin ein Balgen 8 an, der in eine ausziehbare Gießtülle 9 übergeht.In the figure, an area of a plastic container 1 blown as a hollow body is shown broken off, the removal opening of which is delimited by a connector 2 of the container reinforced at the free end by a collar 3. In the container neck 2, a base part 4 of a closure is pressed in such a way that its flange 5 lies firmly on the end face of the container neck 2 and the pipe extension 6 adjoining the flange 5 engages in the container neck 2, sealed by its elastic sealing lamellae. Since there is no anchoring behind the removal opening, it is also not necessary for the tube extension 6 to protrude inward beyond the container neck 2; it can be of the same length or shorter than the container neck. A bellows 8 continues to connect to the flange and merges into an extendable pouring spout 9.

In der Figur ist im links dargestellten Halbschnitt die Gießtülle 9 in ihre Ausgangsstellung eingedrückt gezeigt, während der gegenüberliegende Halbschnitt sie in die Entnahmestellung herausgezogen offenbart. Das Außengewinde der Gießtülle 9 ist im dargestellten, eingeschobenen und verschlossenen Zustande von einem Gewindeansatz 10 umgriffen, der an der Kopfscheibe 11 einer Schraubkappe 12 angeordnet ist. Die Kopfscheibe ist in den beiden Halbschnitten mit unterschiedlichen der möglichen Ausbildungen dargestellt. Nach dem rechten Halbschnitt ist sie mit einem in Randnähe angeordneten Randwulst 13 zunächst nach oben gezogen, bspw. um die gleiche Höhe zu erreichen, den ein die Handhabung des Kunststoffbehälters erleichternder Griff aufweist, so daß beim Verpacken beispielsweise Kartons durch gleiche Höhe des Griffes und der Schraubkappe günstiger abgestützt sind. An den Randwulst 13 schließt sich ein Mantel 14a an, der zur Erleichterung der Handhabung mit einer Riffelung 15 versehen ist. - In einfacheren Fällen kann die Kopfscheibe auch nach dem links gezeigten Halbschnitt als Platte beispielsweise gleichbleibender Stärke ausgeführt sein, deren Randbereich als Mantel 14b dient und mit einer entsprechenden Textur versehen ist. Das Herunterziehen des Mantels 14a jedoch vergrößert dem Behälterinhalt gebotene Kriechstrecken und erlaubt damit eine saubere, durch den Behälterinhalt nicht beeinträchtigte Handhabung. Ein keilförmig profilierter Ringansatz 16 legt sich beim Aufschrauben der Schraubkappe zusätzlich dichtend gegen die Innenwand der Gießtülle 9.In the figure, the pouring spout 9 is shown pressed into its initial position in the half-section shown on the left, while the opposite half-section reveals it to be pulled out into the removal position. In the illustrated, inserted and closed state, the external thread of the pouring spout 9 is encompassed by a threaded attachment 10 which is arranged on the top plate 11 of a screw cap 12. The head disc is shown in the two half-cuts with different possible designs. After the right half-cut, it is first pulled upwards with an edge bead 13 arranged near the edge, for example in order to achieve the same height as a handle which facilitates the handling of the plastic container, so that when packaging, for example, boxes have the same height as the handle and Screw cap are supported cheaper. A jacket 14a adjoins the edge bead 13 and is provided with a corrugation 15 to facilitate handling. - In simpler cases, the head disc even after the half-cut shown on the left as a plate, for example of constant thickness, the edge region of which serves as a jacket 14b and is provided with a corresponding texture. The pulling down of the jacket 14a, however, increases the creepage distances offered by the container contents and thus permits clean handling which is not impaired by the container contents. When the screw cap is screwed on, a wedge-shaped profiled ring shoulder 16 additionally seals against the inner wall of the pouring spout 9.

Der sichere Halt des aufgesetzten Basisteils 4 wird durch einen zusätzlichen, U-förmig profilierten Ring 17 erreicht. Dieser Ring übergreift mit seinem oberen Schenkel 18 den Flansch 5, und mit seinem unteren Schenkel 19 die untere Bundfläche 20 des Bundes 3 des Behälterstutzens 2. Zur Erleichterung des Aufbringens des Ringes 17 ist dessen unterer Schenkel 19 sägezahnartig so profiliert, daß seine flache Flanke 21 nach unten zeigt, während die obere, steile Flanke 25 wie die Bundfläche 20 des Bundes 3 achsnormal oder geringfügig hinterschnitten verläuft. Der Verschluß kann entweder mit oberhalb des Ringes aufgeschraubter Schraubkappe geliefert werden, so daß beim Einführen des Verschlusses der Rohreinsatz 6 ebenso eingeführt wird wie die untere Flanke 21 des Ringes 17 über den Bund 3 gleitet. Erleichtert wird dieses noch durch eine Anfasung 22 des Bundes 3, die gegebenenfalls auch noch bis über den Behälterstutzen 2 selbst geführt sein kann. Bei entsprechend hartem Kunststoff des Ringes 17 wird bei entsprechender Anfasung einerseits ein relativ einfaches Aufdrücken erreicht, während andererseits ein unbeabsichtigtes Lösen infolge der Breite der Bundfläche 20 und der unteren Flanke 21 in Verbindung mit den achsnormal bzw. hinterschnitten verlaufenden Flächen praktisch unmöglich ist. Andererseits ist es aber auch möglich, zunächst den Basisteil 4 in den Behälterstutzen 2 einzuführen, ihn anschließend durch Aufpressen des Ringes 17 zu fixieren und erst nachträglich die Schraubkappe 12 aufzubringen.The attached base part 4 is held securely by an additional, U-shaped ring 17. This ring overlaps with its upper leg 18 the flange 5, and with its lower leg 19 the lower collar surface 20 of the collar 3 of the container neck 2. To facilitate the application of the ring 17, its lower leg 19 is sawtooth-shaped so that its flat flank 21st shows downwards, while the upper, steep flank 25, like the collar surface 20 of the collar 3, runs axially normal or slightly undercut. The closure can either be supplied with a screw cap screwed on above the ring, so that when the closure is inserted, the tube insert 6 is inserted as well as the lower flank 21 of the ring 17 slides over the collar 3. This is further facilitated by a chamfer 22 of the collar 3, which can optionally also be guided over the container neck 2 itself. With a correspondingly hard plastic of the ring 17, with a corresponding chamfer, on the one hand a relatively simple pressing on is achieved, while on the other hand an unintentional loosening due to the width of the collar surface 20 and the lower flank 21 in connection with the axially normal or undercut surfaces is practically impossible. On the other hand, it is also possible to first insert the base part 4 into the container neck 2, then fix it by pressing on the ring 17 and only subsequently apply the screw cap 12.

Die Erfindung ist einer Reihe von Varianten fähig, und auch der dargestellte Verschluß läßt sich weiterbilden. So kann bspw. die Schraubkappe mit das Hochziehen der Gießtülle 9 erleichternden Elementen ausgestattet sein, wie bspw. um Filmscharniere schwenkbare und mit zum Eingreifen der Finger vorgesehenen Öffnungen ausgestattete Bügel. Ebenso wird man im allgemeinen den Verschluß zusätzlich mit Siegelvorrichtungen ausstatten. Bewährt hat es sich hierbei, in einer Teilhöhe der Gießtülle selbst eine diese abschließende Sperrfolie vorzusehen, die vermittels eines in eine Handhabe endenden Aufreißstreifens entfernbar ist, ohne daß durch diese Angaben die möglichen Ausgestaltungen eingeschränkt sind.The invention is capable of a number of variants, and the closure shown can also be developed. For example, the screw cap can be equipped with elements that facilitate the pulling up of the pouring spout 9, such as, for example, brackets that can be pivoted about film hinges and have openings provided for engaging the fingers. Likewise, the closure will generally be additionally equipped with sealing devices. It has proven to be useful in this case to provide a sealing film which closes the pouring spout itself and can be removed by means of a tear strip ending in a handle, without the possible configurations being restricted by this information.

Im allgemeinen wird man mit Rücksicht auf den Balgen das Basisteil des Verschlusses aus relativ weichem, elastischen Kunststoff herstellen, während der Ring 17 aus verhältnismäßig hartem Kunststoff erstellt wird, um einen unbedingten, sicheren Halt zu erreichen und jegliches Ausweichen unter Fremdkräften sicher zu unterbinden. Es besteht aber auch die Möglichkeit, einen Kunststoff mittlerer Härte zu verwenden, und den Ring 17 einstückig mit dem Basisteil so zu erstellen, daß der Flansch 5 gleichzeitig den oberen Schenkel 17 des Ringes bildet. Insbesondere bei Basisteilen, die keinen Balgen aufweisen, läßt sich für diesen und den einstückig mit ihm erstellten Ring auch ein härterer Kunststoff verwenden; das bedarfsweise Auskragen der Gießöffnung kann in solchen Fällen durch ein im Basisteil verschiebbar geführtes Gießrohr erreicht werden. Andererseits kann aber auch ein aus Metall bestehender, vorzugsweise ein aus Metallblech geformter bzw. profilierter, gezogener und/oder gedrückter, den Bund 3 hintergreifender Ring zur Verbindung des Stutzens 2 mit einem Basisteil 4 eingesetzt werden. Ein solcher aus Metall bzw. Metallblech bestehender Ring wird zweckmäßig bereits fertig profiliert über den Flansch 5 und den Bund 3 einrastend geschoben; der Ring kann hierbei ein im wesentlichen U-förmiges Profil aufweisen, dessen oberer Schenkel sich rechtwinklig oder mit einem 90° nur geringfügig unterschreitenden Winkel an das den Mantel bildende Joch anschließt, während der untere Schenkel an das Joch mit einem 90° deutlich unterschreitenden Winkel angeformt ist. Es besteht jedoch auch die Möglichkeit, einen Ring zu verwenden, der nur einen oberen Flansch, im Profil als Schenkel bezeichnet, aufweist, und dessen Joch zunächst glatt ausgeführt ist oder mit mit einem noch nicht ausgeprägt ausgeformten Schenkel versehen ist. Nach Aufsetzen eines solchen, nur teilweise vorgeformten Metallringes auf den Flansch 5 und den Stutzen 2 wird erst jetzt der untere Schenkel durch Prägen, Einrollen oder dergleichen fertig geformt, so daß er sich unter der gewünschten Vorspannung unter die Bundfläche 20 legt und den Flansch 5 gegen die Stirnfläche des Behälterstutzens 2 vorspannt.In general, with regard to the bellows, the base part of the closure will be made of relatively soft, elastic plastic, while the ring 17 is made of relatively hard plastic in order to achieve an unconditional, secure hold and to reliably prevent any evasion by external forces. But there is also the possibility to use a plastic of medium hardness, and to create the ring 17 in one piece with the base part so that the flange 5 simultaneously forms the upper leg 17 of the ring. In particular in the case of base parts which do not have a bellows, a harder plastic can also be used for this and the ring made in one piece with it; in such cases the protruding cantilever of the pouring opening can be achieved by a pouring tube which is displaceably guided in the base part. On the other hand, it is also possible to use a ring made of metal, preferably a sheet metal formed or profiled, drawn and / or pressed, which engages behind the collar 3 for connecting the connecting piece 2 to a base part 4. One made of metal or The metal sheet of the existing ring is appropriately already profiled and pushed over the flange 5 and the collar 3 into place; the ring can have an essentially U-shaped profile, the upper leg of which adjoins the yoke forming the jacket at a right angle or at an angle which is only slightly below 90 °, while the lower leg is integrally formed on the yoke at an angle which is clearly below 90 ° is. However, there is also the possibility of using a ring which has only an upper flange, referred to as a leg in the profile, and whose yoke is initially smooth or is provided with a leg which has not yet been shaped to a great extent. After placing such a, only partially preformed metal ring on the flange 5 and the socket 2, the lower leg is only now finished by stamping, rolling or the like, so that it lies under the desired prestress under the flange surface 20 and the flange 5 against prestresses the end face of the container neck 2.

Weitere Weiterbildungen sind anhand der Fig. 2 erläutert. Der Fig. 1 entsprechende Teile sind zur Erleichterung der Übersicht mit gleichen Referenznummern bezeichnet.Further developments are explained with reference to FIG. 2. Parts corresponding to FIG. 1 are labeled with the same reference numbers to facilitate the overview.

Auf den im Halbschnitt abgebrochen dargestellten Kunststoffbehälter 1 ist ein Basisteil 4 eines Verschlusses aufgesetzt, dessen Rohransatz 6 in den Stutzen 2 des Kunststoffbehälters 1 eingreift. Zur Abdichtung ist der Rohransatz 6 mit Dichtlippen 7 versehen, und an seinem inneren, freien Ende weist er eine ringförmige Verstärkung 23 auf, welche auch bei der dargestellten geringen Länge des Rohransatzes erhebliche Kräfte aufzunehmen vermag, ohne daß Dichtlamellen 7 überstark verformt werden und damit in ihrer Dichtwirkung beeinträchtigt werden. Andererseits wird der Bund 3 des Stutzens 2 nicht nur vom Flansch 5 des Basisteils 4 übergriffen. An den Flansch schließt sich noch ein Rohransatz 24 an, welcher zur Verbesserung der Dichtung den Bund 3 umgreift. Um die sperrende Wirkung des Ringes 17 nicht zu beeinträchtigen, erstreckt sich der Rohransatz 24 höchstens bis zur unteren Bundfläche des Bundes 3, d.h., nur über eine Teillänge dieses Bundes.A base part 4 of a closure is placed on the plastic container 1, shown broken off in half section, the tube extension 6 of which engages in the socket 2 of the plastic container 1. For sealing, the tube extension 6 is provided with sealing lips 7, and at its inner, free end it has an annular reinforcement 23, which is able to absorb considerable forces even with the short length of the tube extension shown, without sealing strips 7 being excessively deformed and thus in their sealing effect are impaired. On the other hand, the collar 3 of the socket 2 is not only overlapped by the flange 5 of the base part 4. A pipe extension 24 connects to the flange, which grips around collar 3 to improve the seal. In order not to impair the locking effect of the ring 17, the tube extension 24 extends at most to the lower surface of the federal government 3, that is, only over a partial length of this federal government.

Falls gewünscht, läßt sich die Schraubkappe zusätzlich mit eine unberechtigte Entnahme anzeigenden Sicherungselementen verbinden oder ausstatten.If desired, the screw cap can also be connected or equipped with securing elements that indicate an unauthorized removal.

Die Reihe der möglichen Varianten läßt sich fortführen; in jedem Falle jedoch wird ein leicht zu montierender und festsitzender Verschluß für einen Kunststoffbehälter geschaffen, der sich preisgünstig mit einfachen Werkzeugen herstellen läßt, der einen sicheren, verschiebungsfreien Sitz gewährleistet, und der auch ohne besondere Vorkehrungen eine restlose Entleerung des Behälters erlaubt.The series of possible variants can be continued; in any case, however, an easy-to-assemble and tight closure for a plastic container is created, which can be inexpensively manufactured with simple tools, which ensures a secure, displacement-free fit, and which permits complete emptying of the container even without special precautions.
