Description
Die vorliegende Erfindung betrifft einen Behälter für viskose Massen, insbesondere kosmetische Mittel, wie Zahnpasten der die dosierte Abgabe seines Inhaltes gestattet, aus wenigen Teilen besteht und daher einfach herstellbar ist, und der die bekannten ähnlichen Behältern anhaftenden Nachteile nicht besitzt.The present invention relates to a container for viscous compositions, in particular cosmetic agents, such as toothpaste, which allows the metered delivery of its contents, consists of a few parts and is therefore easy to manufacture, and which does not have the disadvantages inherent in the known similar containers.
Aus der DE-OS Nr. 2 611 644 ist bereits ein Behälter für viskose Kosmetika, insbesondere Zahnpasta, bekannt, der einen verschiebbaren, den Boden des Behälters bildenden Kolben, der durch eine Sperrklinke gegen Verschiebung nach außen gesichert sein soll, sowie einen vor dem Kolben liegenden, zusammendrückbaren Behälterteil mit einem Entnahmemundstück aus biegsamem und elastischem Material, insbesondere aus einem Polyester-Elastomer, und ein bei Überdruck im Behälter öffnendes Abgabeventil aufweist, wobei dieses Abgabeventil aus Kunststoff besteht, vor dem Einlauf-Querschnitt des Entnahmemundstücks angeordnet und topfförmig geformt ist, wobei der Topfboden als Klappenventil in Form einer kreisrunden, angelegten Klappe ausgebildet ist und die Klappe den lichten Einlauf-Querschnitt ausfüllt und in der Schließstellung gegen einen dem Ventilgelenk gegenüberliegenden, in den freien Ventil-Querschnitt hineinragenden Vorsprung anliegt und sich in der öffnungsstellung bei Überdruck im Behälter gegen die Federkraft des Gelenkes von ihrem Sitz entfernt, wobei die Klappe einen Durchmesser von höchstens 10 mm aufweisen soll.From DE-OS No. 2 611 644 a container for viscous cosmetics, in particular toothpaste, is already known, which has a displaceable piston forming the bottom of the container, which is to be secured against displacement to the outside by a pawl, and one in front of the Piston-lying, compressible container part with a removal mouthpiece made of flexible and elastic material, in particular made of a polyester elastomer, and a dispensing valve that opens in the container when there is excess pressure, this dispensing valve consisting of plastic, arranged in front of the inlet cross section of the sampling mouthpiece and shaped like a pot , wherein the bottom of the pot is designed as a flap valve in the form of a circular flap and the flap fills the clear inlet cross-section and, in the closed position, bears against a projection opposite the valve joint and projects into the free valve cross-section and in the open position when there is overpressure in the container away from the seat against the spring force of the joint, the flap should have a diameter of at most 10 mm.
Diese genau einzuhaltende Ausgestaltung des Ventils bedingt naturgemäß einen fertigungstechnisch sehr hohen Aufwand, d.h., der bekannte Behälter besteht aus vielen Teilen, die ineinander gepaßt werden müssen, was die Herstellung ebenfalls schwierig gestaltet und verteuert. Darüberhinaus besitzt dieser bekannte Behälter den Nachteil, daß bei der Abgabe des Inhalts, die durch Druckausübung mittels des Entnahmemundstücks auf den zusammendrückbaren Behälterteil bewirkt wird, eine hohe Kraftanwendung erforderlich ist, wobei jedoch durch die Elastizität dieses Behälterteils und eine fehlende Führung des Mundstücks eine genaue Dosierung des auszudrückenden Inhalts nicht möglich ist. Schließlich ist eine vollständige Füllung auch des elastischen Behälteroberteils unbedingt erforderlich, da sonst, aufgrund von Lufteinschlüssen, ein zuverlässiges Funktionieren des Behälters nicht gewährleistet ist.This design of the valve, which must be observed exactly, naturally requires a very high level of production engineering, i.e. the known container consists of many parts that have to be fitted into one another, which also makes production difficult and more expensive. In addition, this known container has the disadvantage that a high level of force is required when dispensing the content, which is brought about by the application of pressure by means of the removal mouthpiece to the compressible container part, but due to the elasticity of this container part and a lack of guidance of the mouthpiece, an exact dosage is required of the content to be expressed is not possible. Finally, a complete filling of the elastic upper part of the container is absolutely necessary, since otherwise reliable functioning of the container cannot be guaranteed due to air pockets.
Durch die vorliegende Erfindung werden diese Nachteile des bekannten, gattungsgleichen Dosier-Behälters vermieden.The present invention avoids these disadvantages of the known, generic dosing container.
Der erfindungsgemäße Behälter besteht ebenfalls aus einem zylindrischen Grundkörper mit einem darin verschiebbaren, seinen Boden bildenden Kolben, der gegen eine Verschiebung nach außen (also im Sinne der Erweiterung des Behälter-Innenraumes) gesichert ist, sowie einem aus einem elasti--schen, zusammendrückbaren Material bestehenden Behälteroberteil mit einem einseitig offenen Entnahmemundstück, wobei dieses Entnahmemundstück, das im Oberteil des Behälters, vorzugsweise im Übergang des starren zylindrischen in den elastischen, oberen Behälterteil, mittels Steghalterungen befestigt ist, gleichzeitig eine Ventilfunktion ausübt und die Ventil-Öffnungen so angeordnet sind, daß sie im geschlossenen Zustand innerhalb des durch die stegförmigen Halterungen gebildeten Halteringes liegen und beim Ausüben von Druck auf das Entnahmemundstück durch die Führung des Halteringes in den Behälter hineingedrückt werden, wobei. der Behälterinhalt durch das rntnahmemundstück nach außen entweichen kann.The container according to the invention also consists of a cylindrical base body with a displaceable piston forming its bottom, which is secured against displacement to the outside (in the sense of expanding the interior of the container), and of an elastic, compressible material existing container upper part with a removal mouthpiece open on one side, this removal mouthpiece, which is fastened in the upper part of the container, preferably in the transition from the rigid cylindrical to the elastic, upper container part, by means of web holders, simultaneously performs a valve function and the valve openings are arranged in such a way that they lie in the closed state within the retaining ring formed by the web-shaped holders and are pressed into the container by the guide of the retaining ring when pressure is exerted on the removal mouthpiece, wherein. of the container contents can escape through the rnt n ahmemundstück outward.
Durch diese erfindungsgemäße konstruktive Ausgestaltung wird ein einfach herstell- und montierbarer, aus wenigen, unkomplizierten Einzelteilen bestehender Behälter erhalten, der billig herstellbar ist und aufgrund seiner fixierten Mundstückführung auch die genaue Dosierung des abzugebenden Tubeninhaltes gestattet, ohne dafür einen übermäßigen Kraftaufwand erforderlich zu machen.This constructive configuration according to the invention provides a container which is simple to manufacture and assemble and which consists of a few, uncomplicated individual parts, which can be produced cheaply and, because of its fixed mouthpiece guide, also permits the precise metering of the tube contents to be dispensed without requiring excessive effort.
