Description

Die Erfindung betrifft eine Vorrichtung zum Austragen eines flüssigen oder pastösen Mediums unter Verwendung eines unter Druck stehenden Treibmittels. Ein solcher Abgabekopf kann auf ein Ventil mit Beutel aufgesetzt werden.The invention relates to a device for discharging a liquid or pasty medium using a pressurized propellant. Such a dispensing head can be placed on a valve with bag.

Abgabeköpfe oder auch Dispenserköpfe unterscheiden sich von Sprühköpfen dadurch, daß ein gleichmäßiger und kontinuierlicher Strom des auszutragenden Mediums abgegeben wird. Hierbei kann es sich flüssige oder pastöse Medien handeln, wie beispielsweise Make-up, die mit einem vorbestimmten Volumenstrom ausgebracht werden. Bevorzugt werden für solche Medien sogenannte Beutelventile, auch als BOV-Ventile (Bag-on-Valve-Ventil) eingesetzt. Bei einem Beutelventil befindet sich innerhalb des Beutels das auszutragende Medium und ein außerhalb des Beutels angeordnetes unter Druck stehendes Treibmittel drückt das Medium aus dem Beutel über das Ventil und den Abgabekopf hinaus. Wichtig hierbei ist, daß der Auftrag des Mediums mit dem gewünschten Volumenstrom erfolgt. Hierzu muß der Dispenserkopf an die Eigenschaften des Mediums angepaßt werden.Dispensing heads or dispensing heads differ from spray heads in that a uniform and continuous flow of the discharged medium is delivered. This may be liquid or pasty media, such as make-up, which are applied with a predetermined volume flow. For such media, so-called bag valves are preferably used, also as BOV valves (bag-on-valve valve). In the case of a bag valve, the medium to be discharged is located inside the bag, and a pressurized propellant disposed outside the bag pushes the medium out of the bag beyond the valve and the dispensing head. It is important that the order of the medium is carried out with the desired volume flow. For this purpose, the dispenser head must be adapted to the properties of the medium.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Abgabekopf bereitzustellen, der bei einer einfachen Bauweise das auszutragende Medium in der gewünschten Menge austrägt.The present invention has for its object to provide a dispensing head, which discharges the discharged medium in the desired amount in a simple construction.

Erfindungsgemäß wird die Aufgabe durch einen Abgabekopf mit den Merkmalen aus Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen bilden die Gegenstände der Unteransprüche.According to the invention the object is achieved by a dispensing head having the features of claim 1. Advantageous embodiments form the subject of the dependent claims.

Fig. 3 shows the holding member 12 with the channel portion 26. The channel portion 26 has in the region of the inlet opening a portion with a holding projection 36 for receiving the valve seat. The retaining projection 36 is followed by a cylindrical holding section 38. Following this, the diameter widened in a portion 39 and is subsequently limited by a holding portion 40 which widens conically on the side facing away from the inlet opening. The channel section 26 further has a receiving region 42 for the capillary tube 14. The capillary tube is in the inserted state on the projection 36.

Das von der Eintrittsöffnung 24 fortweisende Ende des Kanalabschnitts 26 besitzt eine konische Erweiterung 46, an die sich der Ansatz 32 mit einer Rückwand 34 anschließt. Der Ansatz 32 besitzt ungefähr Quaderform, vergleiche Fign. 4, wobei die Rückwand 34 durch zwei Seitenwände 35 begrenzt ist, um eine Vertiefung zu bilden. Im eingesetzten Zustand ist der Kapillarschlauch 14 durch den Ansatz 32 geführt.The end facing away from the inlet opening 24 of the channel portion 26 has a conical extension 46, to which the projection 32 connects to a rear wall 34. The projection 32 has approximately cuboid shape, cf. FIGS. 4, wherein the rear wall 34 is bounded by two side walls 35 to form a recess. In the inserted state, the capillary tube 14 is guided through the projection 32.

Der Halteabschnitt 28 ist nachfolgend an die konische Erweiterung 46 um ungefähr 90° abgewinkelt. Wie aus Fig. 5 ersichtlich, ist der Halteabschnitt 28 an der von der Biegung fortweisenden Seite offen ausgebildet, wobei sich eine Ausnehmung zur Aufnahme des Kanalelements mit einem abgerundeten Grund bildet. Beabstandet voneinander sind in dem Halteabschnitt 28 drei in Längsrichtung des Halteelements verlaufende Vorsprünge 50 vorgesehen, die den eingesetzten Kapillarschlauch 14 in dem Halteabschnitt 28 durch Längsrippen 51 halten.The holding section 28 is subsequently angled at approximately 90 ° to the conical extension 46. As shown in Fig. 5, the holding portion 28 is formed open at the side facing away from the bend, wherein a recess for receiving the channel member forms with a rounded base. Spaced apart from one another, three projections 50 extending in the longitudinal direction of the holding element are provided in the holding section 28, which retain the inserted capillary tube 14 in the holding section 28 by longitudinal ribs 51.

Aus Fig. 6 ist der Abgabekopfkörper 10 in dem Schnitt aus Fig. 1 perspektivisch dargestellt. Der Vorsprung 52 aus Fig. 1, der im Druckbereich 22 in den Abgabekopfkörper 10 vorsteht und an der Rückwand 34 anliegt, ist mittig geschnitten, so daß in Fig. 6 nur eine Wand 53 dargestellt ist, die sich rückseitig an den Vorsprung 52 anschließt. Die Wand 53 steht ebenfalls aus dem Abgabekopfkörper in Längsrichtung des Halteabschnitts 28 vor. Ferner ist in Fig. 6 ein Vorsprung 54 an der Austrittsöffnung sichtbar, der sich wie Wand 53 in Richtung des Halteabschnitts 28 erstreckt und in Figur 9 von vorne dargestellt ist. Benachbart zu dem Vorsprung 52 ist ein zweiter Vorsprung 55 vorgesehen, der sich parallel zu dem ersten Vorsprung 52 erstreckt, jedoch kürzer ist. Der Vorsprung 52 besitzt ein im Querschnitt keilförmiges Ende. Im montierten Zustand befindet sich die Rückwand 34 zwischen den Vorsprüngen 52 und 55, wodurch das Halteelement auch bei einer Betätigung sicher gehalten wird.From Fig. 6, the dispenser head body 10 is shown in perspective in the section of Fig. 1. The projection 52 of FIG. 1, which protrudes into the discharge head body 10 in the pressure region 22 and bears against the rear wall 34, is cut centrally, so that only one wall 53 is shown in FIG. 6, which adjoins the projection 52 at the rear. The wall 53 also protrudes from the dispenser head body in the longitudinal direction of the holding portion 28. Further, in Fig. 6, a projection 54 is visible at the outlet opening, which extends like wall 53 in the direction of the holding portion 28 and is shown in Figure 9 from the front. Adjacent to the projection 52, a second projection 55 is provided which extends parallel to the first projection 52, but is shorter. The projection 52 has a wedge-shaped in cross-section. In the assembled state, the rear wall 34 is located between the projections 52 and 55, whereby the holding element is held securely even when actuated.

Fig. 8 zeigt eine Detailansicht im Bereich der Austrittsöffnung 62 mit einem Schlitz 63. Schnappnasen 56 begrenzen eine teilweise runde Öffnung. Zur Verbindung des Halteelements 12 mit dem Abgabekopfkörper 10 wird das Halteelement im Bereich seines Halteabschnitts 28 nahe der Austrittsöffnung zwischen die Schnappnasen 56 eingeschnappt und gehalten. Vorsprung 54 (vergl. Fign. 6, 7) liegt von oben an dem Kanalelement 14 an. Schlitz 63 erleichtert einerseits die Montage des Halteelements und erlaubt andererseits, daß bei viskosen Medien ein sich an der Öffnung des Kanalelements bildender Tropfen zurückfließt und nicht in dem Kanalelement eintrocknet.Fig. 8 shows a detailed view in the region of the outlet opening 62 with a slot 63. Snap tabs 56 define a partially circular opening. To connect the retaining element 12 with the dispensing head body 10, the retaining element is snapped and held in the region of its holding portion 28 near the outlet opening between the snap-in lugs 56. The projection 54 (see Figures 6, 7) abuts the channel element 14 from above. Slit 63 facilitates on the one hand the mounting of the holding element and on the other hand allows for viscous media, a forming at the opening of the channel element drops back and does not dry in the channel element.

Fig. 7 zeigt einen Schnitt durch den Abgabekopfkörper 10. Auf der Innenseite des Betätigungsbereichs 22 sind zwei beabstandete zueinander angeordnete Vorsprünge 58 vorgesehen, die jeweils auf ihren einander zugewandten Seiten Anlageflächen 60 in Form eines Absatzes besitzen. Im eingesetzten Zustand des Halteelements steht der Vorsprung 52 über den Ansatz 32 hinaus und liegt flächig an der Rückwand 34 an. Der Vorsprung 58 besitzt zwei Rastelemente 59 mit jeweils einer Anlagefläche 60, die an der Seitenwand des Ansatzes anliegen.7 shows a section through the dispensing head body 10. Provided on the inside of the actuating region 22 are two spaced-apart projections 58, each of which has contact surfaces 60 in the form of a shoulder on their mutually facing sides. In the inserted state of the holding element, the projection 52 protrudes beyond the projection 32 and rests flat against the rear wall 34. Of the Projection 58 has two latching elements 59, each with a contact surface 60, which bear against the side wall of the approach.

Zur Betätigung des erfindungsgemäßen Abgabekopfs wird eine Kraft auf die Betätigungsmulde 22 ausgeübt. Über den Vorsprung 58 und die Anlagefläche 60 wird die Kraft auf den Ansatz 32 übertragen und drückt das Halteelement 12 auf das Ventil. Die Rastelemente 59 halten dabei das Halteelement seitlich. Das Ventil öffnet und das Gemisch aus Medium und Treibgas tritt in den Kapillarschlauch 14 ein, wo es unter dem Druck des nachströmenden Mediums ausgetragen wird. Über die Austrittsöffnung 62 tritt das Medium aus. Sobald keine Kraft mehr auf die Betätigungsmulde 22 ausgeübt wird, schließt das Ventil und der Sprühvorgang ist beendet.For actuating the dispensing head according to the invention, a force is exerted on the actuating recess 22. Via the projection 58 and the contact surface 60, the force is transmitted to the projection 32 and presses the retaining element 12 onto the valve. The locking elements 59 hold the retaining element laterally. The valve opens and the mixture of medium and propellant gas enters the capillary tube 14, where it is discharged under the pressure of the inflowing medium. About the outlet opening 62, the medium exits. As soon as no force is exerted on the actuating trough 22, the valve closes and the spraying process is completed.

Fig. 10 zeigt ein an sich bekanntes Ventil, mit einem Ventilteller 100, der in seiner Mitte domförmig vorsteht. Der Ventilteller 100 ist mit einer Außendichtung 102 versehen, mit der das Ventil gegenüber dem Behälter abgedichtet wird. Eine innere Dichtung 104 dichtet das Ventilgehäuse 106 gegenüber dem Ventilteller 100 ab. Das Ventilgehäuse 106 besitzt eine Feder 108, die einen Ventilkörper 110 gegen die innere Dichtung 104 drückt. Das dargestellte Ventil in Fig. 10 ist als weibliches Ventil ausgebildet. Selbstverständlich kann der vorbeschriebene Abgabekopf mit entsprechender Modifikation auch mit einem männlichen Ventil zusammenwirken.Fig. 10 shows a per se known valve, with a valve plate 100 which protrudes dome-shaped in its center. The valve disk 100 is provided with an outer seal 102, with which the valve is sealed against the container. An inner seal 104 seals the valve housing 106 from the valve disk 100. The valve housing 106 has a spring 108 that urges a valve body 110 against the inner seal 104. The illustrated valve in Fig. 10 is formed as a female valve. Of course, the above-described dispensing head with corresponding modification can also interact with a male valve.

In Fig. 10 ist ferner der Ansatz für ein Steigrohr 112 zu erkennen, das in einen Beutel 114 taucht. Der Beutel 114 ist aus mehreren Lagen hergestellt, beispielsweise bei einem vierlagigen Beutel aus PET/ALU/OPa/PP oder PE, bei einem dreilagigen Beutel sind Lagen aus Pa/ALU/PP oder PE vorgesehen. Der Beutel 114 ist an den Ventilkörper 106 angeschweißt und entlang der Schweißnaht 116 verschlossen.In Fig. 10 also the approach for a riser 112 can be seen, which dips into a bag 114. The bag 114 is made of several layers, for example in a four-ply bag of PET / ALU / OPa / PP or PE, in a three-ply bag layers of Pa / ALU / PP or PE are provided. The bag 114 is welded to the valve body 106 and sealed along the weld 116.
