Description

Die Erfindung betrifft einen selbsttätigen Verschluß für einen zur Aufnahme eines flüssigen oder pastösen Füllgutes bestimmten, flexiblen Behälter, insbesondere Tube für Hautcreme, Shampoo und dergl., mit einem in der auf den Durchtrittskanal des Behälters aufsetzbaren Verschlußkappe angeordneten Lippenventil aus elastischem Material, das mit einem aus dem Durchtrittskanal herausragenden Dichtungskörper zusammenwirkt.The invention relates to an automatic closure for a flexible container intended for holding a liquid or pasty filling material, in particular a tube for skin cream, shampoo and the like cooperating sealing body protruding from the passage.

In der internationalen PCT-Anmeldung WO 82/00128 ist ein selbsttätiger Behälterverschluß beschrieben, bei dem die Verschlußkappe eine Membrane mit ringförmiger Dichtungslippe aufweist, die mit einem auf den Durchtrittskanal des Behälters aufgeklipsten Dichtungskörper zusammenwirkt. Wenn der Behälter mit der Hand zusammengedrückt wird, hebt das Füllgut die Membrane an und kann durch die von der Dichtungslippe freigegebene Öffnung im Zentrum der Membrane nach außen austreten. Wird auf den Behälter kein Druck mehr ausgeübt, dann kann durch ein Ventil im Dichtungskörper Luft in den Behälter eintreten, so daß er seine ursprüngliche Form wieder annimmt, während die Membrane der Verschlußkappe wieder in ihre Schließstellung zurückgeht und ihre ringförmige Dichtungslippe sich an den Dichtungskörper dichtend anlegt. Soll die Behälteröffnung fest verschlossen werden, so daß auch bei starkem Druck auf den Behälter z.B. beim Transport, kein Füllgut austreten kann, dann wird durch eine Drehung der Verschlußkappe, die auf den Dichtungskörper drehbar aufgesetzt ist, die Membrane in ihrer Schließstellung arretiert. Die bekannte Verschlußanordnung ist jedoch kompliziert im Aufbau und umständlich in der Handhabung, kostspielig in der Herstellung der Einzelteile und ihrer Montage und erfordert eine Verdrehsicherung für den im Hals des Behälters angebrachten Dichtungskörper.In the international PCT application WO 82/00128, an automatic container closure is described, in which the closure cap has a membrane with an annular sealing lip which interacts with a sealing body clipped onto the passage of the container. When the container is pressed together by hand, the filling material lifts the membrane and can escape to the outside through the opening in the center of the membrane exposed by the sealing lip. If pressure is no longer exerted on the container, air can enter the container through a valve in the sealing body, so that it returns to its original shape, while the membrane of the closure cap returns to its closed position and its annular sealing lip seals against the sealing body creates. If the container opening is to be closed tightly so that no filling material can escape even when there is strong pressure on the container, for example during transport, then the membrane is locked in its closed position by rotating the closure cap, which is rotatably fitted onto the sealing body. However, the known closure arrangement is complicated in construction and cumbersome to handle, expensive in the manufacture of the individual parts and their assembly and requires an anti-rotation device for the sealing body attached in the neck of the container.

Aufgabe der Erfindung ist es daher, den bekannten Verschluß zu verbessern und die Einzelteile und ihre Montage zu vereinfachen, um eine kostengünstige Massenfertigung und eine leichte Handhabung zu gewährleisten.The object of the invention is therefore to improve the known closure and to simplify the individual parts and their assembly in order to ensure inexpensive mass production and easy handling.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das Lippenventil in eine Öffnung der axial verstellbaren Verschlußkappe eingesetzt wird und seine Halterung zwei Dichtungsflächen für den Dichtungskörper aufweist.This object is achieved according to the invention in that the lip valve is inserted into an opening in the axially adjustable closure cap and its holder has two sealing surfaces for the sealing body.

Der erfindungsgemäße Verschluß läßt sich in vorteilhafter Weise leicht und ohne viel Arbeitsaufwand an dem Durchtrittskanal des Behälters anbringen. Das Einsetzen des Lippenventils in die Verschlußkappe und das Einsetzen des Dichtungskörpers in den Durchtrittskanal bzw. den Hals des Behälters erfordert keine besonderen Hilfsmittel und kann ohne viel Zeitaufwand von Hand erfolgen. Wegen der einfachen Gestaltung der Einzelteile lassen sich diese aus Kunststoff im Spritzverfahren kostengünstig herstellen, so daß die Voraussetzungen für eine wirtschaftliche Massenfertigung gegeben sind. Der Verschluß kann beispielsweise als Drehverschluß oder als Zieh-Druckverschluß ausgebildet sein.The closure according to the invention can advantageously be easily and without much effort attach the passage of the container. The insertion of the lip valve into the closure cap and the insertion of the sealing body into the passage channel or the neck of the container does not require any special aids and can be done by hand without much time. Because of the simple design of the individual parts, these can be produced inexpensively from plastic by injection molding, so that the conditions for economical mass production are met. The closure can be designed, for example, as a rotary closure or as a push-pull closure.

Weitere Fortbildungen und Ausgestaltungen sowie weitere Vorteile der Erfindung können aus den Unteransprüchen, aus der Zeichnung und aus der zugehörigen Zeichnungsbeschreibung entnommen werden.Further developments and refinements and further advantages of the invention can be found in the subclaims, in the drawing and in the associated description of the drawing.

In der Zeichnung sind zwei Ausführungsbeispiele gemäß der Erfindung dargestellt, und zwar zeigt:

  • Fig. 1 einen Längsschnitt durch den oberen Teil einer zusammendrückbaren Kunststofflasche, deren drehbare Verschlußkappe sich in Schließstellung befindet,
  • Fig. 2 einen Querschnitt entlang der Linie II - II in Fig. 1,
  • Fig. 3 einen Schnitt entlang der Linie III - III in Fig. 1,
  • Fig. 4 eine Draufsicht auf die Kunststofflasche nach Fig. 3,
  • Fig. 5 eine von Hand zusammengedrückte Flasche mit einem Längsschnitt durch den Verschluß, dessen Verschlußkappe sich in Offenstellung befindet,
  • Fig. 6 eine Draufsicht auf die Flasche nach Fig. 5 und
  • Fig. 7 einen Längsschnitt durch eine weitere Ausführungsform des Verschlusses mit auf- und abbewegbarer Verschlußkappe in Schließstellung.
The drawing shows two exemplary embodiments according to the invention, namely:
  • 1 shows a longitudinal section through the upper part of a compressible plastic flap, the rotatable closure cap of which is in the closed position,
  • 2 shows a cross section along the line II-II in FIG. 1,
  • 3 shows a section along the line III-III in FIG. 1,
  • 4 shows a plan view of the plastic bottle according to FIG. 3,
  • 5 a hand-compressed bottle with a longitudinal section through the closure, the closure cap of which is in the open position,
  • Fig. 6 is a plan view of the bottle of Fig. 5 and
  • Fig. 7 shows a longitudinal section through a further embodiment of the closure with up and down movable closure cap in the closed position.

Die Kunststofflasche 1 nach Fig. 1 bis 4 besitzt an ihrem oberen Ende einen den Durchtrittskanal 2 bildenden Hals 3 mit Außengewinde 4, auf das die mit Innengewinde 5 versehene Verschlußkappe 6 aufgeschraubt ist. In eine zentrale Öffnung 7 der Verschlußkappe 6 ist ein Lippenventil 8 mit seiner Halterung 9 eingesetzt, die eine Ringnut 10 zur Aufnahme des Randes der Öffnung 7 aufweist. Das Lippenventil 8 kann aus Kunststoff, Gummi oder einem anderen elastischen Material hergestellt sein, so daß ein leichtes Einsetzen in die Verschlußkappenöffnung 7 möglich ist. An die Halterung 9 ist eine Dichtungsmanschette 11 mit Dichtungsfläche 12 angesetzt. Die Dichtungsmanschette 11 verhindert, daß Füllgut in das Gewinde 4, 5 eindringt und die Verschlußkappe 6 am Flaschenhals 3 festbackt. In den Durchtrittskanal 2 ist ein Dichtungskörper 15 eingesetzt, der mit einer im wesentlichen konischen Dichtungsfläche 16 in der Halterung 9 des Lippenventils 8 zusammenwirkt und in der Schließstellung nach Fig. 1 und 3 ein Auslaufen von Füllgut verhindert, wenn z.B. beim Transport der Flasche 1 ein Druck auf diese ausgeübt wird. Die Dichtungsmanschette 11 greift dichtend in eine ringförmige Aussparung 17 des Dichtungskörpers 15 ein, so daß kein Füllgut in das Gewinde 4 am Flaschenhals 3 gelangen kann. Die ringförmige Aussparung 17 besitzt Durchtrittsöffnungen 20 und 21 für das Füllgut. Die Außenwand 22 des Dichtungskörpers 15 liegt dichtend am Hals 3 der Flasche 1 an und besitzt einen Ringflansch 23 als Anschlag für den Rand des Durchtrittskanals 2. Ein abgeschrägter Ringwulst 25 am freien Ende des Halses 3 wirkt zur Bildung einer Schnappverbindung mit einem Ringwulst 26 an der Innenseite der Verschlußkappe 6 zusammen, so daß sich diese nach dem Aufsetzen auf die Flasche 1 nur durch einen größeren Kraftaufwand vom Flaschenhals 3 abschrauben oder abziehen läßt.The plastic flap 1 according to FIGS. 1 to 4 has at its upper end a neck 3 with an external thread 4 forming the passage channel 2, onto which the closure cap 6 provided with an internal thread 5 is screwed. In a central opening 7 of the cap 6, a lip valve 8 is inserted with its holder 9, which has an annular groove 10 for receiving the edge of the opening 7. The lip valve 8 can be made of plastic, rubber or another elastic material, so that easy insertion into the cap opening 7 is possible. A sealing collar 11 with a sealing surface 12 is attached to the holder 9. The sealing collar 11 prevents the filling material from penetrating into the threads 4, 5 and the sealing cap 6 from sticking to the bottle neck 3. In the passage channel 2, a sealing body 15 is inserted, which cooperates with an essentially conical sealing surface 16 in the holder 9 of the lip valve 8 and in the closed position according to FIGS. 1 and 3 a leakage of filling is prevented if, for example, pressure is exerted on the bottle 1 during transport. The sealing sleeve 11 engages in a sealing manner in an annular recess 17 in the sealing body 15, so that no filling material can get into the thread 4 on the bottle neck 3. The annular recess 17 has through openings 20 and 21 for the filling material. The outer wall 22 of the sealing body 15 lies sealingly against the neck 3 of the bottle 1 and has an annular flange 23 as a stop for the edge of the passage channel 2. A beveled annular bead 25 at the free end of the neck 3 acts to form a snap connection with an annular bead 26 on the Inside of the cap 6 together, so that it can only be unscrewed or pulled off from the bottle neck 3 by placing a greater force on the bottle 1.

In der Schließstellung nach Fig. 1 ragt der zapfenförmige Dichtungskörper 15 in die Halterung 9 des Lippenventils 8 hinein und liegt an der Dichtungsfläche 16 an. Es kann dann kein Füllgut aus dem Lippenventil 8 austreten, selbst dann nicht, wenn ein größerer Druck auf die Flasche ausgeübt wird, wie dies beim Transport der Fall sein kann. Wird die Verschlußkappe 6 in die Stellung nach Fig. 5 hochgedreht, dann gibt der Dichtungskörper 15 den Durchtritt für das Füllgut frei, wie dies durch die Pfeile 30 angedeutet ist, so daß beim Drücken der Flasche 1 das Füllgut durch den von den beiden Lippen 31 und 32 gebildeten Schlitz 33 nach außen tritt, da der Druck des Füllgutes die beiden Lippen 31 und 32 des Lippenventils 8 auseinandertreibt und ein Öffnen des Schlitzes 33 bewirkt, wie dies aus Fig. 6 ersichtlich ist. Beim Nachlassen des Druckes auf die Flasche 1 wird Außenluft in diese durch das Lippenventil 8 gesaugt, bis sich beide Lippen 31 und 32 wieder schließen und die Flasche 1 ihre ursprüngliche Form angenommen hat. Die Lippen 31 und 32 bilden jetzt einen selbsttätig sich öffnenden und schließenden Verschluß, wobei die Verschlußkappe in der Stellung nach Fig. 5 verbleibt, also nicht gedreht werden muß. Ein Zurückdrehen der Verschlußkappe 6 in die Stellung nach Fig. 1 ist erst dann wieder erforderlich, wenn die Flasche 1 längere Zeit nicht benutzt oder aber zu einem weiter entfernten Ort transportiert werden soll. Zum vollständigen Entleeren eines Füllgutrestes oder zum. Nachfüllen der Flasche 1 mit Füllgut wird sowohl die Verschlußkappe 6 als auch der Dichtungskörper 15 vom Flaschenhals 3 entfernt.In the closed position according to FIG. 1, the peg-shaped sealing body 15 projects into the holder 9 of the lip valve 8 and lies against the sealing surface 16. No filling material can then escape from the lip valve 8, even if a greater pressure is exerted on the bottle, as can be the case during transport. 5, the sealing body 15 clears the passage for the filling material, as indicated by the arrows 30, so that when the bottle 1 is pressed, the filling material by the lips 31 and 32 formed slot 33 comes out, since the pressure of the filling material drives the two lips 31 and 32 of the lip valve 8 apart and causes the slot 33 to open, as shown in FIG. 6 can be seen. When the pressure on the bottle 1 decreases, outside air is sucked into it through the lip valve 8 until both lips 31 and 32 close again and the bottle 1 has assumed its original shape. The lips 31 and 32 now form an automatically opening and closing closure, the closure cap remaining in the position shown in FIG. 5, so it does not have to be rotated. A turning back of the closure cap 6 into the position according to FIG. 1 is only necessary again when the bottle 1 is not to be used for a long time or is to be transported to a more distant place. For complete emptying of a product residue or for. Refilling the bottle 1 with the filling material removes both the closure cap 6 and the sealing body 15 from the bottle neck 3.

Die Ausführungsform nach Fig. 7 besitzt eine auf- und abbewegbare Verschlußkappe 34. In diesem Fall treten an die Stelle des Gewindes 4 und 5 eine zylindrische äußere Mantelfläche 36 am Flaschenhals 35 und eine umlaufende Rippe 37 auf der Innenseite der Verschlußkappe 34, die miteinander dichtend so zusammenwirken, daß die-Verschlußkappe 34 mit der Rippe 37 auf der äußeren Mantelfläche 36 axial verschiebbar geführt wird.The embodiment according to FIG. 7 has a cap 34 that can be moved up and down. In this case, the thread 4 and 5 are replaced by a cylindrical outer circumferential surface 36 on the bottle neck 35 and a circumferential rib 37 on the inside of the cap 34, which seal together cooperate so that the closure cap 34 is guided axially displaceably with the rib 37 on the outer circumferential surface 36.

Es gibt noch weitere, mannigfaltige Abwandlungsmöglichkeiten in der Gestaltung der Einzelteile des erfindungsgemäßen Verschlusses und in deren Anordnung, so daß die Erfindung nicht auf die beiden in der Zeichnung dargestellten und oben beschriebenen Ausführungsbeispiele beschränkt ist.There are still further, diverse possible modifications in the design of the individual parts of the closure according to the invention and in their arrangement, so that the invention is not limited to the two exemplary embodiments shown in the drawing and described above.
