The ring-shaped channel is closed by a ring-shaped closure flap (20) which on opening, due to the pressure of the medium present in the container (10), defines a ring-shaped gap opening (21). The actuation element is part of the container cap (24).

Description

Die Erfindung betrifft eine Vorrichtung zum dosierten Austrag eines fließfähigen Mediums, insbesondere einer pastösen Masse, wie Creme, Gel oder dergleichen, bestehend aus einem Behälter mit einem Abgabeventil, welches ein entgegen der Wirkung eines elastischen Elements in das Behälterinnere hinein bewegbares und/oder um seine Längsachse kippbares Abgaberöhrchen umfaßt.The invention relates to a device for the metered discharge of a flowable medium, in particular a pasty mass, such as cream, gel or the like, consisting of a container with a dispensing valve, which is movable against the action of an elastic element into the container interior and / or around it Includes longitudinally tiltable dispensing tube.

Derartige Vorrichtungen sind allgemein bekannt. Sie weisen jeweils einen Behälter mit einer Behälteröffnung auf, die durch einen Deckel verschließbar ist. Der Deckel weist ebenfalls eine Öffnung auf, an der ein Abgabeventil befestigbar ist. Diese Konstruktion ist insbesondere in Verbindung mit sogenannten Aerosol-Dosen bekannt.Such devices are generally known. They each have a container with a container opening that can be closed by a lid. The lid also has an opening to which a dispensing valve can be attached. This construction is particularly known in connection with so-called aerosol cans.

Im vorliegenden Fall geht es um die vorteilhafte Ausbildung eines Betätigungselements für das Abgaberöhrchen, wobei das Betätigungselement zugleich einen für das Abstreichen der pastösen Masse vorteilhaften Austragsmechanismus aufweisen soll.In the present case, it is a question of the advantageous design of an actuating element for the dispensing tube, the actuating element at the same time being intended to have a discharge mechanism which is advantageous for wiping off the pasty mass.

Dieses Ziel wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Dementsprechend ist das Abgaberöhrchen mit einem einen ringförmigen Kanal aufweisenden Betätigungselement koppelbar derart, daß der ringförmige Kanal mit dem Abgaberöhrchen fluidverbunden ist, wobei der ringförmige Kanal durch einen ringförmigen Schließlappen verschlossen ist, der bei Öffnung unter Druck eine ringförmige Spaltöffnung zum Austritt des Mediums definiert. Diese Konstruktion erlaubt ein bequemes und rückstandsfreies Abstreifen des austretenden Mediums von der ringförmigen Spaltöffnung mit dem Finger des Benutzers. Darüber hinaus ist gewährleistet, daß in Schließstellung der Vorrichtung bzw. des Abgabeventils im Betätigungselement befindliches Medium durch den ringförmigen Schließlappen gegenüber der Umgebung hermetisch abgedichtet ist. Dementsprechend erfolgt keine vorzeitige Oxidation des sich nach erstmaligem Gebrauch der Vorrichtung im Betätigungselement ansammelnden Mediums. Dies gilt insbesondere dann, wenn der ringförmige Schließlappen entsprechend Anspruch 9 in Schließrichtung vorgespannt ist.This object is achieved by the characterizing features of claim 1. Accordingly, the delivery tube can be coupled to an actuating element having an annular channel in such a way that the annular channel is fluidly connected to the delivery tube, the annular channel being closed by an annular closing flap which, when opened under pressure, defines an annular gap opening for the exit of the medium. This construction allows a convenient and residue-free stripping of the emerging medium from the annular gap opening with the user's finger. Beyond that ensures that in the closed position of the device or of the dispensing valve, the medium located in the actuating element is hermetically sealed from the surroundings by the annular closing flap. Accordingly, there is no premature oxidation of the medium that accumulates in the actuating element after the device has been used for the first time. This applies in particular if the annular closing flap is prestressed in the closing direction.

Weitere konstruktive Details der erfindungsgemäßen Vorrichtung sind in den Unteransprüchen beschrieben.Further structural details of the device according to the invention are described in the subclaims.

An embodiment of the device according to the invention is explained in more detail below with reference to the accompanying drawing. Show it:
Fig. 1
an inventive device partially in longitudinal section, partially in side view, in the closed position of the dispensing valve; and
Fig. 2
part of the device acc. Fig. 1 in longitudinal section and on an enlarged scale, with the dispensing valve open.

In Fig. 1 ist der obere Teil einer Vorrichtung zum dosierten Austrag eines fließfähigen Mediums, insbesondere einer Creme, eines Gels oder dergleichen, in Teilschnitt-Ansicht dargestellt, wobei diese Vorrichtung einen dosenartigen Behälter 10 aufweist, dessen obere Öffnung mit einem Deckel 11 fluiddicht verschlossen ist. Zu diesem Zweck ist zwischen dem oberen Rand der Behälteröffnung und dem Deckelrand eine O-Ringdichtung 12 angeordnet. Im Deckel 11 ist ebenfalls eine Öffnung vorgesehen, an deren Rand ein Abgabeventil fluiddicht befestigt ist. Dieses Abgabeventil umfaßt ein entgegen der Wirkung eines elastischen Elements, insbesondere einer Schraubendruckfeder, in das Behälterinnere hineinbewegbares und/oder um seine Längsachse 13 kippbares Abgaberöhrchen 14.In Fig. 1 the upper part of a device for the metered discharge of a flowable medium, in particular a cream, a gel or the like, is shown in a partial sectional view, this device having a can-like container 10, the upper opening of which is closed with a lid 11 in a fluid-tight manner is. For this purpose, an O-ring seal 12 is arranged between the upper edge of the container opening and the edge of the lid. An opening is also provided in the cover 11, at the edge of which a dispensing valve is fastened in a fluid-tight manner. This dispensing valve comprises a dispensing tube 14 which can be moved into the interior of the container and / or can be tilted about its longitudinal axis 13 counter to the action of an elastic element, in particular a helical compression spring.

Das Abgaberöhrchen 14 steht über den Deckel 11 nach außen vor. Diese Ventilkonstruktion ist allgemein bekannt, insbesondere in Verbindung mit sogenannten Aerosol-Dosen, so daß sich hier eine nähere Beschreibung dieser Konstruktion erübrigt.The dispensing tube 14 protrudes outward through the lid 11. This valve construction is generally known, especially in connection with so-called aerosol cans, so that a more detailed description of this construction is unnecessary here.

Das Abgaberöhrchen 14 ist mit einem Betätigungselement in Form einer Betätigungstaste 15 koppelbar. Zu diesem Zweck ist an der dem Abgaberöhrchen 14 zugewandten Innenseite der Betätigungstaste 15 eine topfartige Aufnahme 16 für das Austrittsende 17 des Abgaberöhrchens 14 ausgebildet, nämlich angeformt, und zwar derart, daß sie das Austrittsende 17 des Abgaberöhrchens 14 eng und dementsprechend fluiddicht umschließt. Der Innenraum 18 der topfartigen Aufnahme 16 ist mit einem an der Außenseite, d. h. dem Behälter 10 abgewandten Seite der Betätigungstaste 15 ausgebildeten Ringkanal 19 fluidverbunden. Dem ringförmigen Kanal 19 ist ein entsprechend ringförmiger Schließlappen 20 zugeordnet, der bei Öffnung des Abgabeventils unter dem Druck des Behälterinhalts eine ringförmige Spaltöffnung 21 zum Austritt des Mediums definiert. Der Austritt des Mediums durch die Spaltöffnung 21 ist in Fig. 2 mit den Pfeilen 22 dargestellt. In Schließstellung definiert der vom ringförmigen Schließlappen 20 begrenzte Zentralbereich 23 sowie der ringförmige Schließlappen 20 selbst eine durchgehend glatte Oberfläche. Der Schließlappen grenzt in Schließstellung bündig am Zentralbereich 23 an. Vorzugsweise ist der ringförmige Schließlappen 20 in Schließstellung vorgespannt, um auf diese Weise bei Nichtbenutzung der Vorrichtung eine hermetische Abdichtung des sich im Innenraum 18 und Ringkanal 19 befindlichen Mediums gegenüber der äußeren Umgebung sicherzustellen. Bei der dargestellten Ausführungsform definiert der ringförmige Schließlappen 19 sowie der Zentralbereich 23 eine flache bzw. ebene Fläche. Diese Fläche kann statt dessen auch entweder geringfügig konvex oder geringfügig konkav gewölbt sein.The dispensing tube 14 can be coupled to an actuating element in the form of an actuating button 15. For this purpose, a pot-like receptacle 16 for the outlet end 17 of the delivery tube 14 is formed, namely molded, on the inside of the actuation button 15 facing the delivery tube 14, namely in such a way that it closely encloses the outlet end 17 of the delivery tube 14 and is accordingly fluid-tight. The interior 18 of the pot-like receptacle 16 is fluidly connected to an annular channel 19 formed on the outside, ie the side of the actuation button 15 facing away from the container 10. A corresponding ring-shaped closing flap 20 is assigned to the annular channel 19 and defines an annular gap opening 21 for the outlet of the medium when the dispensing valve is opened under the pressure of the container contents. The exit of the medium through the gap opening 21 is shown in FIG. 2 with the arrows 22. In the closed position, the central region 23 delimited by the annular closing flap 20 and the annular closing flap 20 itself define a continuously smooth surface. The closing flap is flush with the central area 23 in the closed position. The annular closing flap 20 is preferably pretensioned in the closed position, in order in this way to ensure hermetic sealing of the medium located in the interior 18 and annular channel 19 from the external environment when the device is not in use. In the embodiment shown, the annular closing flap 19 and the central region 23 define a flat or flat surface. Instead, this surface can also be either slightly convex or slightly concave.

Die Betätigungstaste 15 ist Teil einer Behälterkappe 24. Sie ist mit ihrem einen Ende 25 integral mit der Behälterkappe 24 und mit ihrem anderen, relativ zum Abgaberöhrchen 14 bzw. ringförmigen Schließlappen 20 diametralen Ende 26 über eine Garantie-Sollbruchstelle in Form von Sollbruchstegen 27 mit der Behälterkappe verbunden.The actuation button 15 is part of a container cap 24. It is integral with its one end 25 with the container cap 24 and with its other, diametrical end 26 relative to the dispensing tube 14 or annular closing flap 20, via a predetermined breaking point in the form of predetermined breaking bars 27 with the Container cap connected.

Der ringförmige Schließlappen 20 ist Teil eines gesonderten Bauelements 28, welches an der Betätigungstaste 15 in Zuordnung zum Ringkanal 19 befestigbar ist. Zu diesem Zweck ist an der Außenseite der Betätigungstaste 15 eine sich um den Ringkanal 19 herum erstreckende Nut 29 ausgebildet, in die ein komplementärer Ringsteg 30 an dem den Schließlappen 20 aufweisenden Bauelement 28 einsteckbar ist, und zwar mit Preßsitz.The annular locking tab 20 is part of a separate component 28 which can be fastened to the actuation button 15 in association with the ring channel 19. For this purpose, a groove 29 is formed on the outside of the actuation button 15 and extends around the ring channel 19, into which a complementary ring web 30 can be inserted on the component 28 having the locking tab 20, with a press fit.

Die die Betätigungstaste 15 umfassende Behälterkappe 24 ist auf den Umfangsrand 31 des zylindrischen Behälters 10 klemmend aufsteckbar unter gleichzeitiger Erfassung des Abgaberöhrchens 14 durch die topfartige Aufnahme 16 an der Innen- bzw. dem Behälter 10 zugewandten Seite der Betätigungstaste 15. Der innere bzw. dem Abgaberöhrchen 14 zugewandte Umfangsrand 32 der topfartigen Aufnahme 16 für das Abgaberöhrchen 14 bzw. dessen Austrittsende 17 ist radial nach außen konisch bzw. trompetenartig erweitert. Durch diese Maßnahme wird die Montage der Behälterkappe 24 in Zuordnung zum Abgaberöhrchen 14 erleichtert.The container cap 24 comprising the actuation button 15 can be clipped onto the peripheral edge 31 of the cylindrical container 10 while simultaneously capturing the delivery tube 14 through the pot-like receptacle 16 on the side of the actuation button 15 facing the inside or the container 10. The inner or the delivery tube 14 facing peripheral edge 32 of the pot-like receptacle 16 for the dispensing tube 14 or its outlet end 17 is expanded conically or trumpet-like radially outward. This measure makes it easier to assemble the container cap 24 in association with the dispensing tube 14.

Die Betätigungstaste 15 weist am sollbruchseitigen Ende 26 noch eine Drucktaste in Form einer dellenartigen Vertiefung 33 auf.The actuation button 15 also has a push button in the form of a dent-like depression 33 at the end 26 on the breakage side.

Sämtliche in den Anmeldungsunterlagen offenbarten Merkmale werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All features disclosed in the application documents are claimed as essential to the invention, insofar as they are new compared to the prior art, individually or in combination.
