The device for dispensing a flowable substance, in particular a toothpaste, has a container and a metering device which is in connection with said container via a first valve flap and is provided with a pressure piston, which is spring-loaded and is guided in a cylinder, and with an outlet opening which can be closed by a second valve flap, a tubular element being connected downstream of the metering device on the outlet opening, and the tubular element being arranged parallel to the pressure piston of the metering device and off-centre relative to the axis of the cylindrical storage container, and, furthermore, the tubular element being provided at the free end with a closure at the outlet opening, and the tubular element being exchangeable. It is to be possible for different additives to be mixed with the main substance in the region of its outlet section, distributed all-around. This is achieved in that the exchangeable tubular element (13) has a widening (16) and is surrounded in a constructional unit by a concentric chamber (14), which is open towards the second valve flap (12), for receiving a second flowable substance (B), in particular a striped paste, several openings (17) towards the chamber (14) being constructed in the region of the widening (16) of the tubular element (13). The sole figure relating to this is to be published.

Description

Die Erfindung betrifft eine Vorrichtung zur Abgabe eines fließfähigen Stoffes, insbesondere einer Zahncreme mit einem Behälter und mit einer mit diesem über eine erste Ventilklappe in Verbindung stehenden Dosiereinrichtung, welche mit einem von einer Feder beaufschlagten, in einem Zylinder geführten Druckkolben und mit einer durch eine zweite Ventilklappe verschließbaren Austrittsöffnung ver­sehen ist, wobei der Dosiereinrichtung an der Austritts­öffnung ein rohrförmiges Element nachgeschaltet ist, und wobei das rohrförmige Element parallel zum Druckkolben der Dosiereinrichtung und außermittig zur Achse des zylindri­schen Vorratsbehälters angeordnet ist, wobei ferner das rohrförmige Element am freien Ende mit einem Verschluß an der Austrittsöffnung versehen ist, und wobei das rohrförmi­ge Element auswechselbar ist.The invention relates to a device for dispensing a flowable substance, in particular a toothpaste with a container and with a metering device connected to the latter via a first valve flap, which has a pressure piston which is acted upon by a spring and is guided in a cylinder and by a second piston Valve flap closable outlet opening is provided, wherein the metering device is followed by a tubular element at the outlet opening, and wherein the tubular element is arranged parallel to the pressure piston of the metering device and eccentrically to the axis of the cylindrical storage container, wherein the tubular element at the free end with a closure the outlet opening is provided, and wherein the tubular element is interchangeable.

Bekannte Vorrichtungen dieser Art (DE-OS 29 01 717) sind gegenüber herkömmlichen Zahnpastatuben wesentlich leichter zu handhaben, insbesondere, wenn schon ein Teil der Zahn­pasta verbraucht ist, weil ein am der Dosiereinrichtung entgegensetzten Ende des Behälters angeordneter Kolben das im Behälter befindliche Produkt bei Betätigung der verwen­deten Dosiereinrichtung mit Druckkolben und diesem zugeord­neten beiden Ventilklappen ein entsprechendes Hochziehen des Kolbens bewirkt.Known devices of this type (DE-OS 29 01 717) are much easier to handle than conventional toothpaste tubes, especially when part of the toothpaste has already been used up, because a piston arranged at the end of the container opposite the dosing device actuates the product in the container the metering device used with the pressure piston and the two valve flaps assigned to it causes a corresponding lifting of the piston.

Bekannt ist ferner eine Vorrichtung zur Abgabe eines fließ­fähigen Stoffes (EP 0 054 212) zur Abgabe einer Streifen-­Zahncreme mit einem Behälter und mit einer mit diesem in Verbindung stehenden Dosiereinrichtung, welche einen am der Dosiereinrichtung entgegengesetzten Ende des Behälters angeordneten Kolben mittels federbelasteter mechanischer Mittel in Richtung der Dosiereinrichtung bewegt, wobei am Behälterkopf ein rohrförmiges Austrittselement für das im Behälter befindliche Produkt ausgebildet ist sowie zum Be­hälter hin offene Kammern zur Aufnahme eines zweiten fließ­fähigen Produktes, insbesondere einer Streifencreme, wel­che über einen Verbindungsbereich miteinander verbunden sind und den z;eiten fließfähigen Stoff im Austrittsbe­reich des rohrförmigen Austrittselements für den ersten fließfähigen Stoff im Hauptbehälter über eine einzige Ver­bindungsöffnung unmittelbar vor dem Produktaustritt bei­mischen. Mit der bekannten Vorrichtung ist daher nur ein einziger Streifen aus dem zweiten fließfähigen Stoff auf den Hauptproduktstrang aufbringbar und zudem kann immer nur ein einziger Zusatzstoff dem Hauptstoff beigemischt werden.Also known is a device for dispensing a flowable substance (EP 0 054 212) for dispensing a strip toothpaste with a container and with a metering device connected thereto, which has a piston arranged at the end of the container opposite the metering device by means of spring-loaded mechanical means moved in the direction of the metering device, a tubular outlet element for the product located in the container being formed on the container head and chambers open to the container for receiving a second flowable product, in particular a strip cream, which are connected to one another via a connection area and the second flowable Mix in material in the outlet area of the tubular outlet element for the first flowable material in the main container via a single connection opening immediately before the product outlet. With the known device, therefore, only a single strip of the second flowable substance can be applied to the main product strand and, moreover, only a single additive can be added to the main substance.

Aufgabe der Erfindung ist es, unterschiedliche Zusatzstof­fe dem Hauptstoff im Bereich seines Austrittsstranges ringsum verteilt beimischen zu können.The object of the invention is to be able to admix different additives distributed around the main substance in the region of its outlet strand.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß das auswechselbare rohrförmige Element eine Erweiterung aufweist und in baulicher Einheit von einer konzentri­schen, zur zveiten Ventilklappe hin offenen Kammer zur Auf­nahme eines zweiten fließfähigen Stoffes, insbesondere einer Streifencreme, umgeben ist, wobei im Bereich der Er­weiterung des rohrförmigen Elements mehrere Öffnungen zur Kammer vorgesehen sind.This object is achieved according to the invention in that the interchangeable tubular element has an extension and is surrounded in a structural unit by a concentric chamber which is open towards the second valve flap for receiving a second flowable substance, in particular a strip cream, in the region of the extension of the tubular element several openings to the chamber are provided.

Aufgrund dieser Ausbildung ist erkennbar, daß unterschied­liche Zusatzstoffe dem austretenden Strang des Hauptpro­dukts ringsum gleichmäßig verteilt beigegeben werden kön­nen, wobei die Erweiterung am rohrförmigen Element im Be­reich der Einmündungsöffnungen für den zweiten Stoff ge­währleistet, daß trotz der Beimengung des zweiten Stoffes ein kontinuierlich gleichbleibendes Ausfließen des Gesamt­produkts stattfindet.Because of this design, it can be seen that different additives can be added to the emerging strand of the main product evenly distributed all around, the expansion on the tubular element in the area of the orifices for the second substance ensuring that, despite the addition of the second substance, a continuous, constant outflow of the entire product takes place.

Zwar ist es bei herkömmlichen Zahnpastatuben oder dgl. seit langem bekannt (US-PS 2 789 731), von der Tuben­öffnung aus ein Rohrstück in die Tube hineinreichen zu lassen, das an dem der Tubenöffnung zugewandten Ende mit mehreren kleineren Öffnungen versehen ist und im Bereich um das Rohrstück herum eine Streifencreme anzuordnen, wo­bei das Rohrstück in die Basiscreme hineinragt. Dabei steht allerdings am Abgabeende des betreffenden tubenför­migen Behälters der gesamte Querschnitt desselben zur Un­ terbringung der Streifencreme und zur Beimischung zum Hauptproduktstrang zur Verfügung, was eine einfache Über­tragung auf einen Behälter mit Dosiervorrichtung gemäß dem vorbehandelten Stand der Technik ausschließt.It has been known for a long time in conventional toothpaste tubes or the like (US Pat. No. 2,789,731) to allow a tube piece to extend into the tube from the tube opening, which is provided with several smaller openings at the end facing the tube opening and in the area to arrange a strip cream around the tube piece, the tube piece protruding into the base cream. However, the entire cross section of the same is at the delivery end of the tubular container in question Provision of the strip cream and for admixing to the main product strand available, which excludes easy transfer to a container with a metering device according to the pretreated prior art.

Um sicherzustellen, daß trotz Ausweckselbarkeit des zwei­ten fließfähigen Stoffes keine Produktverlauste bzw. Verun­reinigungen bei der Betätigung stattfinden, empfiehlt es sich, zwischen dem auswechselbaren rohrförmigen Element und dem übrigen Teil der Dosiervorrichtung eine Ringdich­tung anzuordnen.In order to ensure that, despite the ability of the second flowable substance to be exchanged, no product loss or contamination occurs during operation, it is advisable to arrange an annular seal between the exchangeable tubular element and the remaining part of the metering device.

Die Erfindung ist nachstehend anhand der Zeichnung bei­spielsweise näher erläutert. Diese zeigt in einem Längs­schnitt schematisch ein Ausführungsbeispiel.The invention is explained below with reference to the drawing, for example. This shows schematically an embodiment in a longitudinal section.

Eine Vorrichtung 1 weist einen Behälter 2 für einen ersten fließfähigen Stoff auf, der in der Zeichnung als Basis­stoff A gekennzeichnet ist. Der Behälter 2 ist in der Zeichnung allerdings nur in seinem oberen Bereich darge­stellt. Durch eine exzentrische Öffnung 3 am oberen Ende des Behälters 2 ist der Behälter 2 mit eine Dosierein­richtung 4 verbunden. Die Dosiereinrichtung 4 besteht aus einem in einem Zylinder 5 geführten Druckkolben 6, der von einer Spiralfeder 7 beaufschlagt wird. Die Spiralfeder 7 ist an ihrem einen Ende an einer mit dem Druckkolben 6 verbundenen beweglichen Drucktaste 8 und an ihrem anderen Ende an einem fest am Behälter 2 angeordneten Kopfstück 9 abgestützt. Die den Durchtritt des Stoffes A in die Dosier­einrichtung 4 ermöglichende Öffnung 3 des Behälters 2 ist mit einer ersten Ventilklappe 10 verschlossen, die die öffnung 3 nur freigibt, wenn im Behälter 2 ein höherer Druck als im Zylinder 5 anliegt.A device 1 has a container 2 for a first flowable substance, which is identified in the drawing as base substance A. The container 2 is shown in the drawing, however, only in its upper area. The container 2 is connected to a metering device 4 through an eccentric opening 3 at the upper end of the container 2. The metering device 4 consists of a pressure piston 6, which is guided in a cylinder 5 and is acted upon by a spiral spring 7. The coil spring 7 is at one end on a movable pushbutton 8 connected to the pressure piston 6 and at the other End supported on a head piece 9 arranged firmly on the container 2. The opening 3 of the container 2 which allows the passage of the substance A into the metering device 4 is closed by a first valve flap 10 which only opens the opening 3 when a higher pressure is present in the container 2 than in the cylinder 5.

An einer Austrittsöffnung 11 der Dosiereinrichtung 4 ist eine weitere zweite Ventilklappe 12 angeordnet, die die Öffnung 11 nur in der Richtung aus der Dosiereinrichtung 4 heraus freigibt.A further second valve flap 12 is arranged at an outlet opening 11 of the metering device 4 and only opens the opening 11 in the direction out of the metering device 4.

Parallel zum Zylinder 5 der Dosiereinrichtung 4 ist ober­halb der Austrittsöffnung 11 ein rohrförmiges, sich erwei­terndes Element 13 angeordnet, das von einer konzentri­schen Kammer 14 umgeben ist. Diese Kammer 14 ist an einem der Austrittsöffnung 11 zugewandten Ende 15 offen. Die konzentrische Kammer 14 nimmt einen zweiten fließfähigen Stoff auf, der in der Zeichnung als Streifencreme B darge­stellt ist. Im Bereich einer Erweiterung 16 des rohrförmi­gen Elementes 13 sind mehrere Öffnungen 17 angeordnet, die den Durchtritt des Stoffes B von der Kammer 14 in das rohr­förmige Element 13 ermöglichen. Das rohrförmige Element 13 mit der konzentrischen Kammer 14 ist herausnehmbar in das Kopfstück 9 eingesetzt. Verbindungsstellen 18 zwischen der konzentrischen Kammer 14 und dem Kopfstück 9 sind z. B. mit einer Ringdichtung abgedichtet. Oberhalb des rohrförmi­ gen Elementes 13 und der konzentrischen Kammer 14 ist ein Verschluß 19 mit einem Austritt 20 angeordnet, in den das rohrförmige Element 13 mündet.Parallel to the cylinder 5 of the metering device 4, a tubular, widening element 13 is arranged above the outlet opening 11 and is surrounded by a concentric chamber 14. This chamber 14 is open at an end 15 facing the outlet opening 11. The concentric chamber 14 receives a second flowable substance, which is shown in the drawing as streak cream B. In the area of an extension 16 of the tubular element 13, a plurality of openings 17 are arranged which allow the passage of the substance B from the chamber 14 into the tubular element 13. The tubular element 13 with the concentric chamber 14 is removably inserted into the head piece 9. Junctions 18 between the concentric chamber 14 and the head piece 9 are, for. B. sealed with a ring seal. Above the tubular gene element 13 and the concentric chamber 14, a closure 19 is arranged with an outlet 20 into which the tubular element 13 opens.

Die Wirkungsweise der Erfindung ist dabei die folgende:The mode of operation of the invention is as follows:

Soll der Vorrichtung 1 ein Produkt entnommen werden, so wird die Drucktaste 8 betätigt. Dadurch bewegt sich der Druckkolben 6 nach unten, wodurch bei erstmaliger Betäti­gung die im Zylinder 5 befindliche Luft aus der Austritts­öffnung 11 über die sich öffnende Ventilklappe 12 durch das rohrförmige Element 13 und den Austritt 20 entweicht. Nach dem Austritt der Luft aus dem Zylinder 5 schlißt die Ventilklappe 12 wieder und durch die Spiralfeder 7 wird der Druckkolben 6 in die Ausgangslage zurückbewegt. Durch den Unterdruck im Zylinder 5 öffnet sich die Ventilklappe 10 und der Stoff A aus dem Behälter 2 wird in den Zylinder 5 gesaugt.If a product is to be removed from the device 1, the push button 8 is actuated. As a result, the pressure piston 6 moves downward, so that when it is actuated for the first time, the air in the cylinder 5 escapes from the outlet opening 11 via the opening valve flap 12 through the tubular element 13 and the outlet 20. After the air has escaped from the cylinder 5, the valve flap 12 closes again and the pressure piston 6 is moved back into the starting position by the spiral spring 7. Due to the negative pressure in the cylinder 5, the valve flap 10 opens and the substance A from the container 2 is sucked into the cylinder 5.

Nach dem Druckausgleich zwischen dem Behälter 2 und dem Zylinder 5 schließt sich die Ventilklappe 10 wieder. Der Zylinder 5 ist nun mit Stoff A gefüllt. Durch erneutes Niederdrücken der Drucktaste 8 wird durch den Druckkolben 6 der Stoff A durch die Austrittsöffnung 11 unddie sich wiederum öffnende Ventilklappe 12 aus dem Zylinder 5 her­ausgepumpt. Der Stoff A tritt nun einerseits in das rohr­förmige Element 13 und andererseits in die offenen Enden 15 der konzentrischen Kammer 14 ein. Dadurch wird auf den Stoff B ein Druck ausgeübt, so daß der Stoff B aus der Kammer 14 durch die Öffnungen 17 entweicht und sich strei­fenförmig mit dem durch die Erweiterung 16 strömenden Stoff A verbindet, bzw. vermischt. Dieser nun streifenför­mige zweikomponentige Stoff A und B tritt anschließend durch den Austritt 20 aus.After the pressure equalization between the container 2 and the cylinder 5, the valve flap 10 closes again. The cylinder 5 is now filled with substance A. By depressing the pushbutton 8 again, the substance A is pumped out of the cylinder 5 by the pressure piston 6 through the outlet opening 11 and the valve flap 12, which in turn opens. The substance A now enters the tubular element 13 on the one hand and the open ends on the other hand 15 of the concentric chamber 14 a. As a result, a pressure is exerted on the substance B, so that the substance B escapes from the chamber 14 through the openings 17 and connects or mixes in strips with the substance A flowing through the extension 16. This now strip-shaped two-component substance A and B then exits through the outlet 20.

Durch die Auswechselbarkeit des rohrförmigen Elementes 13 mit der Kammer 14 ist es möglich, verschiedene Stoffe B mit der Basiscreme A zu kombinieren. Dazu können dem Ver­braucher neben einer vollständigen Vorrichtung 1 mit den Stoffen A und B auch nur mit dem Stoff B gefüllte rohr­förmige Elemente 13 mit den Kammern 14 angeboten werden.The interchangeability of the tubular element 13 with the chamber 14 makes it possible to combine different substances B with the base cream A. For this purpose, in addition to a complete device 1 with the substances A and B, the consumer can also be offered only tubular elements 13 with the chambers 14 filled with the substance B.

Die Erfindung ist natürlich nicht auf das in der Zeichnung dargestellte Ausführungsbeispiel beschränkt. Weitere Ausge­staltungen der Erfindung sind möglich, ohne den Grundge­danken zu verlassen. So kann das rohrförmige Element mit der Kammer auch nicht parallel zum Druckkolben der Dosier­einrichtung angeordenet sein und dgl. mehr.The invention is of course not limited to the embodiment shown in the drawing. Further refinements of the invention are possible without leaving the basic idea. Thus, the tubular element with the chamber can also not be arranged parallel to the pressure piston of the metering device and the like. More.
