Opening of the closure is brought about by pressure on the flexible wall of a flange. A closure cap 2 with an associated sealing ring 4 is arranged on the neck of a bottle 1. The sealing ring 4 is provided with an outer, circumferential sealing lip 6 in the form of a projecting circular ring. A reinforcing plate 5 is assigned a transverse web 3, both parts being surrounded by a softer material, the softer material being injection-moulded onto the reinforcing plate 5 by the two-component injection method. An accumulation of material 9 is injection-moulded onto the underside of the reinforcing plate. The end-side boundary of the reinforcing plate 5 is provided with a lid 12 which can be clipped onto the outer wall of the sealing ring 4. <IMAGE>

Description

Die Erfindung betrifft einen selbstschließenden Verschluß für zur Aufnahme von pastösen oder viskosen Massen bestimmte Behältnisse, insbesondere Tuben, mit einem im Öffnungsbereich des Behältnisses elastisch bewegbar angeordneten Verschlußkörper, wobei durch einen über das Material im Behältnis auf den Verschlußkörper entgegen einer elastischen Kraft ausgeübten Druck eine Freigabe der Öffnung bewirkbar ist.The invention relates to a self-closing closure for containers intended for holding pasty or viscous masses, in particular tubes, with a closure body arranged to be elastically movable in the opening region of the container, a release being exerted against the elastic body by a pressure exerted on the material in the container against an elastic force the opening can be effected.

Verschlüsse der aufgezeigten Gattung sind bekannt. Im allgemeinen sind diese Verschlüsse zweiteilig ausgebildet, wodurch die Herstellung und/oder die Montage und/oder die Bedienung und/oder die Unterhaltung erschwert sind. Außerdem unterliegen diese Verschlüsse einem erhöhten Verschleiß (DE 25 15 095 A1).Closures of the genus shown are known. In general, these closures are formed in two parts, which makes the manufacture and / or assembly and / or operation and / or maintenance more difficult. In addition, these closures are subject to increased wear (DE 25 15 095 A1).

So beschreibt die US 37 54 690 einen Verschluß für flexible Behältnisse, der aus einer am Hals des Behältnisses verrasteten Kappe und einem innerhalb der Kappe angeordneten federbelasteten Ventil besteht. Das Ventil ist aus einer im Bereich der Materialaustrittsöffnung vorgesehenen konischen Ventilplatte gebildet, die mittels einer U-förmigen Blattfeder in der Kappe federnd gehalten ist. Beim Ausüben eines Drucks auf die Außenseiten des Behältnisses wird das in diesem befindliche Material gegen die Unterseite der normalerweise geschlossenen Ventilplatte gedrückt, so daß diese entgegen der Federwirkung die Auslaßöffnung des Behältnisses freigibt.Thus, US 37 54 690 describes a closure for flexible containers, which consists of a latched cap on the neck of the container and a spring-loaded valve arranged inside the cap. The valve is formed from a conical valve plate provided in the area of the material outlet opening, which is held resiliently in the cap by means of a U-shaped leaf spring. When pressure is exerted on the outside of the container, the material in it is pressed against the Bottom of the normally closed valve plate pressed so that it releases the outlet opening of the container against the spring action.

Der Erfindung liegt die Aufgabe zugrunde, einen selbstschließenden Verschluß zu schaffen, der sich äußerst ökonomisch herstellen und montieren läßt und dabei als einstückiger Verschluß in Erscheinung tritt.The invention has for its object to provide a self-closing closure that is extremely economical to manufacture and assemble and thereby appears as a one-piece closure.

Diese Aufgabe wird ausgehend von dem oben dargestellten Stand der Technik erfindungsgemäß durch einen im Öffnungsbereich des Behältnisses angebrachten Quersteg mit längsseitig gelenkig an diesen angeschlossenem Verstärkungsteller, die gemeinsam von einem weichen elastischen Material umschlossen sind, gelöst.Starting from the state of the art described above, this object is achieved according to the invention by a transverse web attached in the opening region of the container with a reinforcing plate articulated on the longitudinal side and jointly enclosed by a soft elastic material.

Das weichere elastische Material ist im Zweikomponenten-Spritzverfahren angespritzt.The softer elastic material is injection molded using the two-component spray process.

Durch die unterschiedlichen Eigenschaften der beiden Materialien wird erreicht, daß auf den Verstärkungsteller eine Federkraft einwirkt, die durch die Zugkraft des weicheren Materials bedingt ist. Diese Federkraft kann dadurch bestimmt bzw. beeinflußt werden, daß auf der Unterseite des Verstärkungstellers erfindungsgemäß eine Materialanhäufung angespritzt ist. Zweckmäßigerweise verläuft die Materialanhäufung seitlich im Mittelbereich des unterhalb des Verstärkungstellers angeordneten Querstegs. Zur Erzielung einer besseren Verbundwirkung der unterschiedlichen Materialien kann der Verstärkungsteller mit Durchbrechungen versehen sein, die zweckmäßigerweise in symmetrischer Anordnung seitlich des Querstegs verlaufen.The different properties of the two materials mean that a spring force acts on the reinforcement plate, which is caused by the tensile force of the softer material. This spring force can be determined or influenced in that, according to the invention, a material accumulation is injection molded onto the underside of the reinforcement plate. The material accumulation expediently runs laterally in the central region of the crossbar arranged below the reinforcement plate. To achieve a better composite effect of the different materials, the reinforcement plate can be provided with openings, which expediently run in a symmetrical arrangement to the side of the crossbar.

In Ausgestaltung der Erfindung weist der Verstärkungsteller mindestens eine am Umfang angeordnete Verankerungsrippe auf, die als Teilkreisring ausgebildet sein kann und die vorteilhafterweise direkt oder indirekt am Behältnis festlegbar ist. Das angespritzte weichere Material kann an der äußeren Begrenzung des Verstärkungstellers als Verschlußdichtung dienen.In an embodiment of the invention, the reinforcement plate has at least one anchoring rib arranged on the circumference, which can be designed as a partial circular ring and which can advantageously be fixed directly or indirectly on the container. The molded, softer material can serve as a seal on the outer boundary of the reinforcement plate.

Bei einer bevorzugten Ausführung des erfindungsgemäßen Verschlusses ist der Verstärkungsteller über ein Filmscharnier an den Quersteg angeschlossen. Der Verstärkungsteller kann direkt an eine Verschlußkappe des Behältnisses angespritzt sein. Es besteht jedoch auch die Möglichkeit, den Verstärkungsteller über einen zusätzlichen Dichtring anzuschließen, wobei durch die Ausbildung des Dichtrings vorteilhafterweise auf die Anordnung einer Verschlußkappe verzichtet werden kann.In a preferred embodiment of the closure according to the invention, the reinforcement plate is connected to the crossbar via a film hinge. The reinforcement plate can be molded directly onto a closure cap of the container. However, there is also the possibility of connecting the reinforcement plate via an additional sealing ring, wherein the arrangement of a sealing cap can advantageously be dispensed with by the design of the sealing ring.

Zum öffnen wird auf die Wandung des Behältnisses ein Außendruck aufgebracht, wodurch der äußere Bereich des Verstärkungstellers in der Gesamtheit oder nur im vorbestimmten Bereich nach oben geschwenkt und damit eine obere Öffnung freigegeben wird. Bei Nachlassen des Drucks wird der Verstärkungsteller infolge der aus dem angespritzten weicheren Material herleitbaren Federkraft und der damit verbundenen Elastizität automatisch wieder in die Ausgangslage zurückgeführt. Durch eine Querschnittsveränderung des angespritzten weichen Materials sowie die Auswahl des Materials kann die Federkraft und damit die Rückverformung beeinflußt werden.For opening, an external pressure is applied to the wall of the container, as a result of which the outer area of the reinforcement plate is pivoted upwards in its entirety or only in the predetermined area, thereby opening up an upper opening. When the pressure drops, the reinforcement plate is automatically returned to the starting position due to the spring force that can be derived from the molded softer material and the associated elasticity. By changing the cross-section of the molded soft Material and the selection of the material can influence the spring force and thus the recovery.

In den Figuren 1 und 2 ist als Behältnis teilweise eine Flasche dargestellt. Am Hals dieses Behältnisses 1 ist eine Verschlußkappe 2 mit zugeordnetem Dichtring 4 angeordnet. Dieser Dichtring 4 besitzt auf seiner Außenseite eine umlaufende Dichtlippe 6, vgl. Figur 6, die als auskragender Kreisring ausgebildet ist. Der Dichtring 4 ist über die Dichtlippe 6 an der Verschlußkappe 2 fest angeordnet.In Figures 1 and 2, a bottle is partially shown as a container. A closure cap 2 with an associated sealing ring 4 is arranged on the neck of this container 1. This sealing ring 4 has a circumferential sealing lip 6 on its outside, cf. Figure 6, which is designed as a projecting circular ring. The sealing ring 4 is fixedly arranged on the sealing cap 2 via the sealing lip 6.

Der Dichtring 4 ist mit einem Quersteg 3 versehen, der damit indirekt fest an der Verschlußkappe 2 bzw. dem Hals des Behältnisses 1 angeordnet ist. Dem Dichtring 4 ist ein Verstärkungsteller 5 zugeordnet, wobei zwischen dem Dichtring 4 und dem Verstärkungsteller 5 als Verbindungselement ein Filmscharnier 7 angeordnet ist. Damit ist eine leichte Beweglichkeit des Verstärkungstellers 5 gewährleistet. Der Quersteg 3 verläuft unterhalb des Mittelpunkts des Verstärkungstellers 5, der mit zwei seitlich des Querstegs 3 angeordneten Durchbrechungen 8 versehen ist.The sealing ring 4 is provided with a crossbar 3, which is thus indirectly fixedly arranged on the closure cap 2 or the neck of the container 1. A reinforcing plate 5 is assigned to the sealing ring 4, a film hinge 7 being arranged between the sealing ring 4 and the reinforcing plate 5 as a connecting element. This ensures easy mobility of the gain adjuster 5. The crosspiece 3 runs below the center of the reinforcement plate 5, which is provided with two openings 8 arranged on the side of the crosspiece 3.

Der Dichtring 4 mit seinem Quersteg 3 und der Verstärkungsteller 5 sind von einem weicheren angespritzten Material 10 umschlossen. Aus Figur 8 ist erkennbar, daß auf der Unterseite des Verstärkungstellers 5 seitlich des Querstegs 3 in dessen Mittelbereich eine Materialanhäufung 9 angespritzt ist. Der Übergang von der Materialanhäufung 9 zum übrigen angespritzten weicheren Material 10 weist eine bogenförmige Begrenzung auf. Die Materialanhäufung 9 verläuft in der Unteransicht gesehen gem. Figur 9 senkrecht zum Quersteg 3 und weist Rechteckform auf. Auf der äußeren Begrenzung des Verstärkungstellers 5 dient das angespritzte weichere Material 10 zugleich als Verschlußdichtung.The sealing ring 4 with its cross bar 3 and the reinforcement plate 5 are enclosed by a softer molded material 10. It can be seen from FIG. 8 that a material accumulation 9 is injection-molded onto the underside of the reinforcement plate 5 to the side of the crossbar 3 in the central region thereof. The transition from the material accumulation 9 to the rest of the injection molded softer material 10 has an arcuate boundary. The accumulation of material 9 runs according to the bottom view. Figure 9 perpendicular to the crossbar 3 and has a rectangular shape. On the outer boundary of the reinforcement plate 5, the molded softer material 10 also serves as a seal.

Der Verstärkungsteller 5 kann umlaufend oder auch nur teilweise durch einen Innendruck zur Bildung einer Öffnung angehoben werden. Die umlaufende Öffnung wird durch einen Kreisring gebildet, der zwischen der Innenseite des Dichtrings 4 und der äußeren Begrenzung des Verstärkungstellers 5 gebildet ist, vgl. Figur 4. Nach Figur 5 ist der Verstärkungsteller 5 nur teilweise angehoben, da auf einem vorbestimmten Umfangsbereich der Verstärkungsteller 5 in seiner Bewegung nach oben gehindert ist. Hierzu dient eine Verankerungsrippe, die am Dichtring 4 angespritzt und in eine Ausnehmung des Verstärkungstellers 5 eingeführt ist. Es besteht auch die Möglichkeit, den Verstärkungsteller 5 mit einer Verankerungsrippe 11 zu versehen und diese in eine Ausnehmung des Dichtrings 4 einzuführen.The reinforcement plate 5 can be raised all around or only partially by an internal pressure to form an opening. The circumferential opening is formed by a circular ring which is formed between the inside of the sealing ring 4 and the outer boundary of the reinforcement plate 5, cf. Figure 4. According to Figure 5, the reinforcement plate 5 is only partially raised, because the reinforcement plate 5 is prevented from moving upward on a predetermined circumferential area. For this purpose, an anchoring rib is injection molded onto the sealing ring 4 and inserted into a recess in the reinforcement plate 5. There is also the possibility of providing the reinforcement plate 5 with an anchoring rib 11 and inserting it into a recess in the sealing ring 4.

Die stirnseitige Begrenzung des Verstärkungstellers 5 ist mit einem Deckel 12 versehen, der auf die Außenwandung des Dichtrings 4 aufklippbar ist.The front end of the reinforcement plate 5 is provided with a cover 12 which can be clipped onto the outer wall of the sealing ring 4.
