Abstract

A dispenser for paste-like products consists of a dispensing head (1) and a cartridge (2) containing the paste-like product. The cartridge has its lower end closed by a follower piston slideable along the interior wall surface of the cartridge under action of the exterior atmosphere. In the dispensing head, a pumping device with a pump chamber is provided. An inlet-check valve is provided for prevention of backflow of paste-like material entering the pump chamber through a passage from the interior of the cartridge. At least one part of the inlet-check valve, for instance, a valve seat thereof or, for instance, all parts of the inlet-check valve, namely, a valve seat and a closure member, are provided on an upper cover wall of the cartridge as part of the cartridge. The cartridge is releasably connectable to the dispensing head. After exhaustion of its contents, the cartridge may be detached from the dispensing head and replaced by a filled cartridge. The dispensing head may be optionally provided with a dummy envelope adapted to surroundingly receive cartridges of different shape and/or volume connected to the dispensing head.

Description

Die Erfindung bezieht sich auf einen Spender für pastöse Produkte.mit einem das jeweilige Produkt enthaltenden, im wesentlichen zylindrischen Behälter und einem am oberen Ende des Behälters vorgesehen Spendekopf, welcher eine Fördereinrichtung, eine Ventileinrichtung und eine Betätigungseinrichtung aufweist,The invention relates to a dispenser for pasty products. With a substantially cylindrical container containing the respective product and a dispensing head provided at the upper end of the container, which has a conveying device, a valve device and an actuating device.

Ein derartiger Spender ist bereits aus der DE-OS 29 01 717 bekannt. Bei Spendern dieser bekannten Gattung sind die mit dem Produkt gefüllten Behälter und die Spendeköpfe jeweils mit einer nicht wieder zu öffnenden Sperrverbindung miteinander verbunden. Folglich werden diese bekannten Spender als Ganzes gehandelt und als Ganzes nach Verbrauch des Behälterinhaltes weggeworfen.Such a dispenser is already known from DE-OS 29 01 717. In the case of dispensers of this known type, the containers filled with the product and the dispensing heads are each connected to one another by a locking connection which cannot be reopened. Consequently, these known dispensers are traded as a whole and thrown away as a whole after the contents of the container have been used up.

Es versteht sich, daß hierin ein beträchtlicher volkswirtschaftlicher Nachteil zu sehen ist, da einerseits beträchtliche Mengen an jeweils geeigneten Kunststoffmaterialien benötigt und verbraucht werden und andererseits die entleerten Spender nur mit entsprechenden Kosten zu beseitigen sind und dabei die Umwelt belasten.It goes without saying that a considerable economic disadvantage is to be seen here, since on the one hand considerable amounts of suitable plastic materials are required and consumed and on the other hand the emptied dispensers can only be removed with corresponding costs and thereby pollute the environment.

Für den Verbraucher besteht ein besonderer Nachteil der bekannten Spender ferner darin, daß er mit jedem neu-erworbenen Spender wiederum einen neuen Spendekopf erwerben muß, der wegen seiner Fördereinrichtung, Ventileinrichtung und Betätigungseinrichtung nicht unbeträchtliche Kosten verursacht.For the consumer, a particular disadvantage of the known dispensers is that he has to purchase a new dispensing head with each newly acquired dispenser, which causes considerable costs due to its conveying device, valve device and actuating device.

Der Erfindung liegt somit die Aufgabe zugrunde, einen Spender für pastöse Produkte der aus der DE-OS 29 01 717 bekannten Gattung so auszugestalten, daß Material- und Kosteneinsparungen erreicht werden können.The invention is therefore based on the object of designing a dispenser for pasty products of the type known from DE-OS 29 01 717 in such a way that material and cost savings can be achieved.

Diese Aufgabe wird bei einem Spender für pastöse Produkte der im Oberbegriff des vorstehenden Anspruchs 1 angegebenen Gattung erfindungsgemäß durch die im Kennzeichenteil des Anspruchs 1 angegebenen Merkmale gelöst.This object is achieved in a dispenser for pasty products of the type specified in the preamble of claim 1 above by the features specified in the characterizing part of claim 1.

Somit ist das Wesen der Erfindung darin zu sehen, daß ein für langzeitige Verwendung bestimmter Spenderkopf als selbstständiges Handelsgut vorgesehen ist, welches mit ge­ füllten Behältern in Form auswechselbarer Kassetten lösbar verbunden werden kann. Ist eine solche Kassette entleert worden, so kann sie durch eine neue Kassette ersetzt werden.Thus, the essence of the invention is to be seen in the fact that a dispenser head intended for long-term use is provided as an independent commercial good which can be releasably connected to filled containers in the form of exchangeable cassettes. If such a cassette has been emptied, it can be replaced by a new cassette.

Der mit Hilfe.der Erfindung erzielbare Vorteil ergibt sich in erster Linie daraus, daß nunmehr unter Verwendung lediglich eines einziges Spendekopfes eine Vielzahl von mit einem pastösen Produkt gefüllte Behälterkassetten nacheinander ihrer Verwendung zugeführt werden können. Ist der Inhalt einer solchen Behälterkassette verbraucht worden, so wird die geleerte Kassette einfach vom Spendekopf gelöst und weggeworfen, worauf eine frische Behälterkassette an den Spendekopf angeschlossen wird.The advantage that can be achieved with the aid of the invention results primarily from the fact that a large number of container cassettes filled with a pasty product can now be supplied one after the other using only a single dispensing head. When the contents of such a container cassette have been used up, the empty cassette is simply detached from the dispensing head and thrown away, whereupon a fresh container cassette is connected to the dispensing head.

Nach einer vorteilhaften Ausführungsform der Erfindung ist vorgesehen, daß wenigstens Teile der Ventileinrichtung an der Kassette ausgebildet sind. So kann beispielsweise der Ventilsitz der im Spendekopf vorgesehenen Ventileinrichtung innerhalb der Kassette angeordnet sein.According to an advantageous embodiment of the invention it is provided that at least parts of the valve device the cassette are formed. For example, the valve seat of the valve device provided in the dispensing head can be arranged within the cassette.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung werden Kassetten unterschiedlicher Gestalt und/oder unterschiedlichen Volumens mit dem Spendekopf verbunden, so daß ein einziger Spendekopf für eine Vielzahl unterschiedlich geformter Kassetten mit unterschiedlich großen Volumina verwendet werden kann, was die Produktionskosten für die Herstellung der Spendeköpfe deutlich herabsetzt.According to a further preferred embodiment of the invention, cassettes of different shapes and / or different volumes are connected to the dispensing head, so that a single dispensing head can be used for a large number of differently shaped cassettes with differently large volumes, which significantly reduces the production costs for the production of the dispensing heads .

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist am Spendekopf eine die Kassette umgebende Scheinhülle ausgebildet, die dauernd mit dem Spendekopf verbunden bleibt und gegebenenfalls ein dekoratives Aussehen aufweist.According to a further advantageous embodiment of the invention, a dummy cover which surrounds the cassette is formed on the dispensing head and remains permanently connected to the dispensing head and may have a decorative appearance.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispieles und unter Bezug auf die Zeichnung näher erläutert. Diese zeigt in schematischer Darstellung einen Spender für pastöse Produkte, bestehend aus einem Spendekopf und einer lösbar daran befestigten auswechselbaren Kassette.The invention is explained below with reference to an embodiment and with reference to the drawing. This shows a schematic representation of a dispenser for pasty products, consisting of a dispensing head and an exchangeable cassette detachably attached to it.

Der in der Zeichnung mit dem Bezugszeichen 1 bezeichnete Spendekopf besitzt in an sich bekannter Weise eine durch äußere Beaufschlagung volumenveränderliche Pumpenkammer, welche mit dem Behälterinneren .durch ein Rückschlagventil verbunden ist. Durch dieses Rückschlagventil gelangt jeweils ein gefördertes Volumen der pastösen Masse über eine Ausgabeeinrichtung nach außen. Zur Betätigung des Spendekopfes wird von Hand das Volumen der Pumpenkammer vermindert, wodurch das in der Pumpenkammer vorliegende Produkt nach außen gefördert wird. Während dieser Verringerung des Pumpenkammervolumens ist das Rückschlagventil geschlossen. Das untere Ende des Spendekopfes 1 und das obere Ende einer mit dem Bezugszeichen 2 bezeichneten auswechselbaren Kassette sind mit Verbindungseinrichtungen, wie einem Schraubgewinde verbunden, so daß eine entleerte Kassette 2 mühelos vom Spendekopf entfernt und durch eine gefüllte, neue, Kassette ersetzt werden kann. Anstelle einer Schraubverbindung kann auch eine Bajonett-Verschluß-Einrichtung oder dergleichen verwendet werden.The dispensing head designated in the drawing with the reference number 1 has, in a manner known per se, a pump chamber which is variable in volume due to external loading and which is connected to the interior of the container by a check valve. Through this check valve, a conveyed volume of the pasty mass passes through an output device to the outside. To actuate the dispensing head, the volume of the pump chamber is reduced by hand, as a result of which the product present in the pump chamber is conveyed to the outside. The check valve is closed during this reduction in the pump chamber volume. The lower end of the dispensing head 1 and the upper end of an exchangeable cassette denoted by the reference number 2 are connected to connecting devices, such as a screw thread, so that an empty cassette 2 can be easily removed from the dispensing head and replaced by a filled, new, cassette. Instead of a screw connection, a bayonet locking device or the like can also be used.

Nach unten ist die Kassette 2 durch einen Hachlaufkolben 3 abgeschlossen, der dichtend an der Innenmantelfläche des Behälters gleitet, um bei einer Produktentnahme aus dem Spender das Volumen der Kassette unter dem Druck der Außenatmosphäre so zu verringern, daß sich bei gleichbleibender äußerer Gestalt der Kassette kein Unterdruck in derselben ausbilden und sich auch keine Luft in derselben ansammeln kann. Am Nachlaufkolben 3 können geeignete Sperrelemente vorgesehen sein, welche dem Nachlaufkolben lediglich eine Aufwärtsbewegung innerhalb der Kassette 2, nicht jedoch eine Abwärtsbewegung gestatten.At the bottom, the cassette 2 is closed off by a run-up piston 3, which slides sealingly on the inner circumferential surface of the container, in order to reduce the volume of the cassette under the pressure of the outside atmosphere when the product is removed from the dispenser in such a way that, with the cassette's external shape remaining the same, none Develop negative pressure in it and no air can accumulate in it. Suitable locking elements can be provided on the trailing piston 3, which only allow the trailing piston to move upward within the cassette 2, but not to move downward.

Wie bereits erwähnt, können wenigstens Teile der Ventileinrichtung, wie der Ventilsitz, an der Kassette 2 ausgebildet sein.As already mentioned, at least parts of the valve device, such as the valve seat, can be formed on the cassette 2.

Im dargestellten schematischen Ausführungsbeispiel weist die Kassette 2 praktisch den gleichen Durchmesser auf wie der Spendekopf 1. Es versteht sich jedoch, daß Kassetten mit durchaus unterschiedlichen Durchmessern und unterschiedlichen Volumina an den Spendekopf angeschlossen werden können, solange gewährleistet ist, daß die jeweiligen Teile der Verbindungseinrichtung 4 zueinander passen.In the illustrated exemplary embodiment, the cassette 2 has practically the same diameter as the dispensing head 1. However, it goes without saying that cassettes with entirely different diameters and different volumes can be connected to the dispensing head as long as it is ensured that the respective parts of the connecting device 4 match each other.

Der Spendekopf 1 kann, wie in der Zeichnung dargestellt, mit einer die Kassette 1 umgebenden Scheinhülle 5 versehen sein, die so bemessen ist, daß auch die größten in Aussicht genommenen Wechselkassetten 2 in derselben aufgenommen werden können. Diese Scheinhülle kann einstückig mit dem Spendekopf ausgebildet sein und gegebenenfalls dekorativ gestaltet sein.The dispensing head 1 can, as shown in the drawing, be provided with a dummy cover 5 surrounding the cassette 1, which is dimensioned such that even the largest in Prospective removable cassettes 2 can be included in the same. This bill envelope can be formed in one piece with the dispensing head and, if appropriate, can be designed in a decorative manner.
