Description

Die Erfindung betrifft ein Gerät zum dosierten Ausbringen von flüssigen Korrekturmitteln, Lacken oder dergleichen Flüssigkeiten gemäß dem Oberbegriff des Patentanspruchs I.The invention relates to a device for the metered application of liquid correcting agents, paints or similar liquids according to the preamble of claim I.

Ein Gerät dieser Gattung ist aus der US-Patentschrift 3 902 815 bekannt. Bei diesem Gerät wird die Austrittsöffnung für die Flüssigkeit an der Spitze des Gehäuses durch ein schaftförmiges Ventilglied verschlossen, das durch eine Druckfeder axial nach vorne in die Schließstellung gedrückt wird. Das in dem Gehäuse des Gerätes vorgesehene Betätigungsmittel weist zwei auseinandergespreizte Blattfedern auf, die sich mit ihrem vorderen Ende an der Innenwand des Gehäuses und mit ihrem hinteren Ende an dem Ventilglied abstützen. Die beiden Blattfedern können durch zwei Drucktasten, die diametral in der Gehäusewand angeordnet sind, zusammengedrückt werden, wodurch das Ventilglied nach hinten bewegt wird und die Austrittsöffnung für die Flüssigkeit freigibt.A device of this type is known from US Pat. No. 3,902,815. In this device, the outlet opening for the liquid at the top of the housing is closed by a shaft-shaped valve member which is pressed axially forward into the closed position by a compression spring. The actuating means provided in the housing of the device has two spread leaf springs which are supported with their front end on the inner wall of the housing and with their rear end on the valve member. The two leaf springs can be pressed together by two pushbuttons which are arranged diametrically in the housing wall, as a result of which the valve member is moved backwards and frees the outlet opening for the liquid.

Zur Betätigung muß das Gerät an genau den diametralen Punkten der Drucktasten zusammengedrückt werden. Dies macht die Handhabung des Gerätes und seine genaue Führung bei der Ausgabe der Flüssigkeit schwierig. Da die Drucktasten in der Gehäusewand radial verschiebbar sind, ist zur Abdichtung des in dem Gehäuse vorgesehenen Vorratsraumes für die Flüssigkeit ein zusätzlicher elastischer Schlauch vorgesehen, der zwischen den Drucktasten und den Blattfedern angeordnet ist. Der zur Abdichtung zusätzlich erforderliche Schlauch macht die Montage und die Abdichtung des Gerätes schwierig. Das aus Drucktasten und Blattfedern bestehende Betätigungsmittel ist in der Konstruktion kompliziert und daher in Herstellung und Montage aufwendig.To operate, the device must be pressed together at exactly the diametrical points of the push buttons. This makes the handling of the device and its precise guidance when dispensing the liquid difficult. Since the push buttons are radially displaceable in the housing wall, an additional elastic hose is provided to seal the storage space provided in the housing for the liquid, which is arranged between the push buttons and the leaf springs. The additional hose required for sealing makes assembly and sealing of the device difficult. The actuating means consisting of pushbuttons and leaf springs is complicated in construction and therefore complex to manufacture and assemble.

Aus der FR-A 1 434 743 ist ein Gerät zum Ausbringen von Flüssigkeiten bekannt, mit einem in einem Gehäuse vorgesehenen Vorratsraum für die Flüssigkeit und einer an der Spitze des Gehäuses vorgesehenen Austrittsöffnung für die Flüssigkeit. In einer ersten Ausführungsform ist ein axiales, die Austrittsöffnung verschließendes Ventilglied fest in dem Gehäuse angeordnet und die Spitze mit der Austrittsöffnung wird zum Ausbringen der Flüssigkeit gegen den Druck einer Feder axial vorgeschoben und von dem Ventilglied abgehoben. Zur axialen Verschiebung der Spitze dienen zwei in dem Gehäuse diametral zueinander angeordnete Hebel, die durch Zusammenpressen des elastisch verformbaren Gehäuses verschwenkt werden und dabei über Nocken die Spitze verschieben. Die verschwenkbaren Hebel nehmen viel Platz in dem Gehäuse ein, so daß das Gerät großvolumig ausgebildet sein muß. Auch bei diesem Gerät muß das Zusammendrücken des Gehäusemantels genau an den diametralen Punkten erfolgen, an welchen die Hebel angeordnet sind. Eine feinfühlige Führung des Gerätes beim Ausbringen der Flüssigkeit ist daher schwierig. In einer zweiten Ausführungsform weist das Gerät eine elastisch auseinanderspreizbare Verschlußkappe auf, die sich beim Zusammendrücken des verformbaren Gehäuses unter dem Druck der Flüssigkeit öffnet und diese austreten läßt. Das Gehäuse muß mit kräftigem Druck zusammengepreßt werden, damit der Flüssigkeitdruck die Verschlußkappe auseinanderspreizt. Dieses kräftige Zusammendrücken steht einer genauen Führung der Spitze mit der Ausgabeöffnung entgegen.A device for dispensing liquids is known from FR-A 1 434 743, with a storage space for the liquid provided in a housing and an outlet opening for the liquid provided at the top of the housing. In a first embodiment, an axial valve member which closes the outlet opening is fixedly arranged in the housing, and the tip with the outlet opening is advanced axially to discharge the liquid against the pressure of a spring and is lifted off the valve member. For axially displacing the tip, there are two levers arranged diametrically to one another in the housing, which are pivoted by pressing together the elastically deformable housing and thereby displacing the tip via cams. The pivotable levers take up a lot of space in the housing, so that the device must be of large volume. In this device, too, the housing casing must be compressed exactly at the diametrical points at which the levers are arranged. Precise guidance of the device when dispensing the liquid is therefore difficult. In a second embodiment, the device has an elastically expandable closure cap which opens when the deformable housing is compressed under the pressure of the liquid and allows it to escape. The housing must be pressed together with vigorous pressure so that the liquid pressure spreads the cap apart. This strong compression stands in the way of precise guidance of the tip with the dispensing opening.

Der Erfindung liegt die Aufgabe zugrunde, ein Gerät der eingangs genannten Gattung zu schaffen, das einfacher und aus wenigen Teilen aufgebaut ist und dadurch in der Herstellung und der Montage sowie in der Adichtung weniger aufwendig ist.The invention has for its object to provide a device of the type mentioned that is simple and made up of a few parts and is therefore less expensive to manufacture and assemble and seal.

Diese Aufgabe wird bei einem Gerät der eingangs genannten Gattung erfindungsgemäß gelöst durch die Merkmale des kennzeichnenden Teils des Patentanspruchs I.This object is achieved according to the invention in a device of the type mentioned at the outset by the features of the characterizing part of patent claim I.

Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Bei dem erfindungsgemäßen Gerät weist das Gehäuse eine durchgehend geschlossene Wand auf, so daß das Gehäuse selbst ohne zusätzliche aufwendige Abdichtungsmaßnahmen den Vorratsraum für die Flüssigkeit bilden kann. Das Betätigungsmittel ist im Inneren des geschlossenen Gehäuses angeordnet und kann von aussen dadurch betätigt werden, daß das Gehäuse im Bereich des Betätigungsmittels elastisch verformbar ausgebildet ist. Zweckmäßigerweise ist das Betätigungsmittel rotationssymmetrisch ausgebildet und kann durch radialen Druck an zwei beliebigen im wesentlichen diametralen Punkten verformt werden. Das Gerät kann daher in beliebiger Drehstellung erfaßt werden und es ist ausreichend, das Gerät im Bereich des elastisch verformbaren Gehäusemantels zwischen zwei Fingern zusammenzudrücken, um das Ventilglied zu verschieben und die Austrittsöffnung für die Flüssigkeit freizugeben.In the device according to the invention, the housing has a continuously closed wall, so that the housing itself can form the storage space for the liquid without additional complex sealing measures. The actuating means is arranged in the interior of the closed housing and can be actuated from the outside in that the housing is designed to be elastically deformable in the region of the actuating means. The actuating means is expediently designed to be rotationally symmetrical and can be deformed by radial pressure at any two essentially diametrical points. The device can therefore be detected in any rotational position and it is sufficient to press the device in the region of the elastically deformable housing shell between two fingers in order to move the valve member and to open the outlet opening for the liquid.

Das Betätigungsmittel ist in einer Ausführungsform als Membranplatte ausgebildet, die unter der Federkraft auf einem kreisringförmigen Sitz gehalten wird und diesen Sitz mit einem abgebogenen Rand übergreift, der innen an dem verformbaren Gehäusemantel anliegt. Die Membran platte ist mit dem Ventilglied verbunden. Wird auf den Rand der Membranplatte an diametralen Punkten ein radialer Druck ausgeübt, so wölbt sich die Membranplatte gegen die Federkraft und hebt von dem Sitz ab. Dadurch wird das Ventilglied zurückgezogen und gibt die Austrittsöffnung frei.In one embodiment, the actuating means is designed as a membrane plate, which is held under the spring force on an annular seat and overlaps this seat with a bent edge which bears against the inside of the deformable housing jacket. The membrane plate is connected to the valve member. If a radial pressure is exerted on the edge of the membrane plate at diametrical points, the membrane plate bulges against the spring force and lifts off the seat. This pulls the valve member back and releases the outlet opening.

Bildet der Sitz einen zylindrischen Ansatz des Gehäuses mit geschlossener Mantelfläche und ist die Membranplatte eine geschlossene Platte, die den Sitz abschließt, so trennen die Membranplatte und dir Sitz den Vorratsraum des Gehäuses dicht gegen die Spitze mit der Austrittsöffnung ab. Herrscht in dem Vorratsraum ein Überdruck, z.B. aufgrund einer Temperaturerhöhung im Vorratsraum oder aufgrund eines Absinkens des Aussenluftdrucks in größerer Höhe, so wird durch diesen Überdruck die Membranplatte zusätzlich auf den Sitz gedrückt und bewirkt eine verstärkte Abdichtung zwischen dem Vorratsraum und der Spitze des Gerätes. Durch diesen Überdruck wird ausserdem die Membranplatte leicht gegen die Spitze hin ausgewölbt, wodurch das Ventilglied mit erhöhtem axialern Druck in die Austrittsöffnung der Spitze gedrückt wird und auch dort die Dichtwirkung verstärkt wird. Ein unbeabsichtigtes Auslaufen der Flüssigkeit bei einem Überdruck in der Flüssigkeit und einem Überdruck im Vorratsraum wird dadurch zuverlässig vermieden.If the seat forms a cylindrical extension of the housing with a closed outer surface and the membrane plate is a closed plate that closes the seat, the membrane plate and the seat separate the storage space of the housing from the tip with the outlet opening. If there is an overpressure in the storage room, e.g. due to an increase in temperature in the storage room or due to a decrease in the outside air pressure at a greater height, this overpressure also pushes the membrane plate onto the seat and creates a stronger seal between the storage room and the tip of the device. This overpressure also causes the diaphragm plate to bulge slightly towards the tip, causing the valve member to have increased axia pressure is pressed into the outlet opening of the tip and the sealing effect is also strengthened there. An unintentional leakage of the liquid in the event of an overpressure in the liquid and an overpressure in the storage space is thereby reliably avoided.

In einer zweiten Ausführungsform ist das Betätigungsmittel als radial verformbarer Vorsprung ausgebildet, der koaxial in dem Gehäuse angeordnet ist. In diesen Vorsprung greift ein koaxialer Konus ein, der an dem Ventilglied angeordnet ist. Wird der Vorsprung durch einen diametral ausgeübten radialen Druck verformt, so schiebt er aufgrund der Keilwirkung des Konus diesen zusammen mit dem Ventilglied nach hinten, so daß die Austrittsöffnung freigegeben wird. Der Vorsprung kann aus achsparallelen Zungen gebildet sein, die über einen Kreisumfang verteilt angeordnet sind. Diese Rippen ermöglichen eine leichte Verformbarkeit in radialer Richtung.In a second embodiment, the actuating means is designed as a radially deformable projection which is arranged coaxially in the housing. A coaxial cone, which is arranged on the valve member, engages in this projection. If the projection is deformed by a diametrically exerted radial pressure, it pushes it backwards together with the valve member due to the wedge effect of the cone, so that the outlet opening is released. The projection can be formed from axially parallel tongues which are arranged distributed over a circumference. These ribs allow easy deformability in the radial direction.

Der Vorsprung kann aber auch ein radial verformbarer geschlossener Zylindermantel sein, wobei der Konus vorzugsweise eine geschlossene Kegelmantelfläche aufweist. In dieser Ausführungsform bilden der zylindrische Vorsprung und der Konus ebenfalls eine zweite zusätzliche Abdichtung zwischen dem Vorratsraum und der Spitze des Gerätes. Diese Abdichtung wird ebenfalls verstärkt, wenn in dem Vorratsraum ein Überdruck herrscht. Der auf den Konus wirkende Überdruck preßt ausserdem auch das Ventilglied verstärkt gegen die Austrittsöffnung, so daß auch dort die Abdichtung verstärkt wird.However, the projection can also be a radially deformable closed cylinder jacket, the cone preferably having a closed conical jacket surface. In this embodiment, the cylindrical projection and the cone also form a second additional seal between the storage space and the tip of the device. This seal is also reinforced if there is overpressure in the storage room. The overpressure acting on the cone also presses the valve member more strongly against the outlet opening, so that the seal is also reinforced there.

In allen Ausführungsformen besteht das Gerät aus wenigen Einzelteilen, die einfach aus Kunststoff herstellbar sind und leicht montiert werden können.In all embodiments, the device consists of a few individual parts that are easy to manufacture from plastic and can be easily assembled.

Im folgenden wird die Erfindung anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher erläutert.The invention is explained in more detail below on the basis of exemplary embodiments illustrated in the drawing.

In dem Ausführungsbeispiel der Figur I weist das Gerät ein Gehäuse 10 in Form eines Schreibgerätes auf, das einen Vorratsraum 12 für eine auszubringende Flüssigkeit, z.B. ein flüssiges Korrekturmittel umschließt. An seinem vorderen Ende weist das Gehäuse 10 eine Spitze 14 auf, in welcher sich eine Austrittsöffnung 16 für die Flüssigkeit befindet. Die Spitze 14 geht mit einer radialen Schulter in den größeren durchmesser des Gehäuses 10 über, so daß auf die Spitze 14 eine Abdeckkappe 18 aufgesetzt werden kann, deren Aussenumfang bündig an den Aussenumfang des Gehäuses 10 anschließt.In the exemplary embodiment in FIG. I, the device has a housing 10 in the form of a writing instrument, which has a storage space 12 for a liquid to be dispensed, e.g. encloses a liquid correction agent. At its front end, the housing 10 has a tip 14, in which there is an outlet opening 16 for the liquid. The tip 14 merges with a radial shoulder into the larger diameter of the housing 10, so that a cover cap 18 can be placed on the tip 14, the outer circumference of which is flush with the outer circumference of the housing 10.

An die Spitze 14 schließt sich ein axialer Abschnitt des Gehäuses 10 an, der als elastisch verformbarer Gehäusemantel 20 mit geringerer Wandstärke ausgebildet ist. Der Gehäusemantel 20 geringerer Wandstärke ist abdichtend auf das anschließende Gehäuse 10 mit größerer Wandstärke aufgepaßt.At the tip 14 there is an axial section of the housing 10, which is designed as an elastically deformable housing jacket 20 with a smaller wall thickness. The housing jacket 20 with a smaller wall thickness is sealingly fitted onto the adjoining housing 10 with a larger wall thickness.

Von der Spitze 14 ausgehend erstreckt sich ein zylindrischer Ansatz 22 koaxial in den Gehäusemantel 20. Der zylindrische Ansatz 22 weist einen radialen Abstand von dem Gehäusemantel 20 auf.Starting from the tip 14, a cylindrical extension 22 extends coaxially into the housing shell 20. The cylindrical extension 22 is at a radial distance from the housing shell 20.

Der zylindrische Ansatz 22 bildet mit seinem freien inneren Ende einen kreisringförmigen Sitz 24 für eine als geschlossene Platte ausgebildete kreisscheibenförmige Membranplatte 26, die elastisch verformbar ist. Die Membranplatte 26 überragt mit einem Rand 28 den Sitz 24. Der Rand 28 ist gegen die Ebene der Membranplatte 26 abgebogen, so daß er in den radialen Zwischenraum zwischen dem zylindrischen Ansatz 22 und dem Gehäusemantel 20 eingreift und von innen an dem Gehäusemantel 20 anliegt.With its free inner end, the cylindrical extension 22 forms an annular seat 24 for a circular disk-shaped membrane plate 26 which is designed as a closed plate and is elastically deformable. The membrane plate 26 projects over the seat 24 with an edge 28. The edge 28 is bent against the plane of the membrane plate 26 so that it engages in the radial space between the cylindrical extension 22 and the housing jacket 20 and abuts the housing jacket 20 from the inside.

Zentrisch an der Membranplatte 26 ist ein Ventilglied 30 in Form eines starren Schaftes angeformt, das in die Spitze hineinragt, dort axial geführt ist und mit einer an seine Spitze ausgebildeten Konusfläche die Austrittsöffnung 16 dichtend verschließt. Eine konische Schraubendruckfeder 32 stützt sich mit ihrem vorderen Ende mit kleinem Durchmesser zentrisch an der Membranplatte 26 und mit ihrem hinteren Ende mit großem Durchmesser an einer Schulter des Gehäuses 10 ab, die durch die Vorderkante des Gehäuseteils mit größerer Wandstärke gebildet wird.A valve member 30 is formed in the center of the membrane plate 26 in the form of a rigid shaft, which projects into the tip, is guided axially there and seals the outlet opening 16 in a sealed manner with a conical surface formed on its tip. A conical compression spring 32 is supported with its front end with a small diameter centrally on the membrane plate 26 and with its rear end with a large diameter on a shoulder of the housing 10, which is formed by the front edge of the housing part with a greater wall thickness.

Der Teil des Gehäuses 10 mit größerer Wandstärke, die Spitze 14 mit dem zylindrischen Ansatz 22 und dem verdünnten Gehäusemantel 20, sowie die Membranplatte mit dem Ventilglied 30 sind jeweils einstückige Kunststoffspritzteile. Aus diesen drei Kunststoffspritzteilen und der Schraubendruckfeder 32, die vorzugsweise ebenfalls aus Kunststoff besteht, ist das gesamte Gerät zusammengesetzt. Daraus ergibt sich die einfache Herstellung und Montage.The part of the housing 10 with a larger wall thickness, the tip 14 with the cylindrical extension 22 and the thinned housing shell 20, and the membrane plate with the valve member 30 are each one-piece plastic injection-molded parts. The entire device is composed of these three plastic injection molded parts and the helical compression spring 32, which preferably also consists of plastic. This results in simple manufacture and assembly.

In der in Figur I dargestellten Stellung drückt die Schraubendruckfeder 32 auf die Membranplatte 26 und hält diese an dem Sitz 24 anliegend. Durch den zentral auf die elastisch verformbare Membranplatte 26 einwirkenden Druck der Schraubendruckfeder 32 wird das zentrisch an der Membranplatte 26 angeformte Ventilglied 30 mit seiner konischen Spitze dichtend in die Austrittsöffnung 16 gedrückt, so daß diese dicht verschlossen ist. Wird der Gehäusemantel 20 im Bereich der Membranplatte 26 an zwei diametralen Punkten radial zusammengedrückt, so wird der Rand 28 an diesen Punkten zusammengedrückt und die Membranplatte 26 wölbt sich gegen den Druck der Schraubendruckfeder 32 längs einer Linie aus, die senkrecht zur Verbindungslinie der Druckpunkte verläuft. Durch diese Auswölbung der Membranplatte 26 wird das Ventilglied 30 axial aus der Austrittsöffnung 16 zurückgezogen, so daß diese Austrittsöffnung freigegeben wird und die Flüssigkeit aus der Spitze 14 aus treten kann.In the position shown in FIG. I, the helical compression spring 32 presses on the membrane plate 26 and holds it against the seat 24. Due to the pressure of the helical compression spring 32 acting centrally on the elastically deformable membrane plate 26, the valve member 30 formed centrally on the membrane plate 26 is pressed with its conical tip into the outlet opening 16 so that it is tightly closed. If the housing jacket 20 is radially compressed in the area of the membrane plate 26 at two diametrical points, the edge 28 is pressed together at these points and the membrane plate 26 bulges out against the pressure of the helical compression spring 32 along a line which runs perpendicular to the connecting line of the pressure points. Due to this bulging of the membrane plate 26, the valve member 30 is withdrawn axially from the outlet opening 16, so that this outlet opening is released is and the liquid can emerge from the tip 14.

Wenn der zylindrische Ansatz 22 mit einer geschlossenen Mantelfläche ausgebildet ist und die Membranplatte 26 eine geschlossene Platte ist, dann wird durch den zylindrischen Ansatz 22 und die unter dem Druck der Schraubendruckfeder 32 dichtend an dem Sitz 24 anliegende Membranplatte 26 der Vorratsraum 12, der die Flüssigkeit enthält, gegen die Spitze 14 mit der Austrittsöffnung 16 abgeschlossen. Dadurch ergibt sich eine zweite Abdichtung zusätzlich zu der Abdichtung der Austrittsöffnung 16 durch das Ventilglied 30.If the cylindrical extension 22 is formed with a closed outer surface and the membrane plate 26 is a closed plate, then the cylindrical extension 22 and the membrane plate 26 sealingly seated against the seat 24 under the pressure of the helical compression spring 32 make the storage space 12, which holds the liquid contains, closed against the tip 14 with the outlet opening 16. This results in a second seal in addition to the sealing of the outlet opening 16 by the valve member 30.

Wird die Membranplatte 26 radial zusammengedrückt, so daß sie sich auswölbt und das Ventilglied 30 aus der Austrittsöffnung 16 herauszieht, so hebt die Membranplatte 26 im Bereich dieser Auswölbung von dem Sitz 24 ab, so daß die Flüssigkeit aus dem Vorratsraum 12 in die Spitze 14 gelangen kann. Beide Abdichtungen des Vorratsraums werden somit durch das radiale Zusammendrücken gleichzeitig geöffnet.If the membrane plate 26 is radially compressed so that it bulges out and pulls the valve member 30 out of the outlet opening 16, the membrane plate 26 lifts off from the seat 24 in the region of this bulge, so that the liquid from the storage space 12 reaches the tip 14 can. Both seals of the storage space are thus opened simultaneously by the radial compression.

Ein in dem Vorratsraum 12 herrschender Überdruck wirkt im gleichen Sinne wie die Schraubendruckfeder 32 auf die Membranplatte 26 und verstärkt deren Abdichtung gegenüber dem Sitz 24 und die Abdichtung der Austrittsöffnung 16 durch das Ventilglied 30.An overpressure prevailing in the storage space 12 acts in the same sense as the helical compression spring 32 on the membrane plate 26 and reinforces its sealing with respect to the seat 24 and the sealing of the outlet opening 16 by the valve member 30.

Figur 2 zeigt das vordere Ende einer zweiten Ausführungsform des Gerätes. Diese Ausführungsform stimmt im wesentlichen mit der Ausführungsform der Figur I überein. Zum Unterschied gegenüber der Ausführungsform der Figur I tritt die Flüssigkeit an der Austrittsöffnung 16 der Spitze 14 nicht unmittelbar aus, sondern gelangt in einen an der Spitze 14 angebrachten Pinsel 34. Die Flüssigkeit kann mittels des Pinsels 34 aufgetragen werden, wie dies z.B. beim Auftragen von Nagellack bevorzugt wird.Figure 2 shows the front end of a second embodiment of the device. This embodiment is essentially the same as the embodiment in FIG. In contrast to the embodiment in FIG. I, the liquid does not exit directly at the outlet opening 16 of the tip 14, but rather passes into a brush 34 attached to the tip 14. The liquid can be applied by means of the brush 34, as is e.g. is preferred when applying nail polish.

Auch in der Gestaltung der Einzelteile zeigt die Ausführungsform der Figur 2 geringe Abweichungen gegenüber der Ausführungsform der Figur I. Die Spitze 14 und der zylindrische Ansatz 22 mit dem Sitz 24 sind als ein Teil ausgebildet, während der verdünnte Gehäusemantel 20 ein einstückiger Bestandteil des gesamten Gehäuses 10 ist. Dementsprechend stützt sich die Schraubendruckfeder 32 an einem innen angespritzten Wulst des Gehäuses 10 ab. Die Abdeckkappe 18 wird auch über den verdünnten Gehäusemantel 20 geschoben, um ein unbeabsichtigtes Zusammendrücken des Gehäusemantels 20 zu vermeiden. Dies ist beispielsweise wichtig, wenn das Gerät zum Aufbringen von Nackellack dient und in der Handtasche aufbewahrt wird.The embodiment of FIG. 2 also shows slight deviations from the embodiment of FIG. 1 in the design of the individual parts. The tip 14 and the cylindrical extension 22 with the seat 24 are formed as one part, while the thinned housing jacket 20 is an integral part of the entire housing 10 is. Accordingly, the helical compression spring 32 is supported on an internally molded bead of the housing 10. The cover cap 18 is also pushed over the thinned housing shell 20 in order to avoid inadvertent compression of the housing shell 20. This is important, for example, if the device is used to apply nack polish and is kept in the handbag.

In den übrigen Merkmalen stimmt das Gerät in der Ausführungsform der Figur 2 mit dem Ausführungsbeispiel der Figur I überein, so daß dieselben Bezugszahlen verwendet werden und auf die dortige Beschreibung verwiesen werden kann.In the other features, the device in the embodiment of FIG. 2 corresponds to the embodiment of FIG. I, so that the same reference numbers are used and reference can be made to the description there.

In dem Ausführungsbeispiel der Figur 3 und 4 ist in Übereinstimmung mit dem Ausführungsbeispiel der Figur I die Spitze 14 einstückig mit dem verdünnten Gehäusemantel 20 ausgebildet, der auf den rückwärtigen Teil des Gehäuses 10 mit größerer Wandstärke aufgepaßt ist. Die Austrittsöffnung 16 wird durch das schaftförmige Ventilglied 30 verschlossen, daß an seinem rückwärtigen Ende einen sich nach hinten erweiternden Konus 36 auf weist.In the exemplary embodiment in FIGS. 3 and 4, in accordance with the exemplary embodiment in FIG. I, the tip 14 is formed in one piece with the thinned housing jacket 20, which is fitted onto the rear part of the housing 10 with greater wall thickness. The outlet opening 16 is closed by the shaft-shaped valve member 30 that has a rearwardly widening cone 36 at its rear end.

In die Spitze 14 ist ein Einsatz 38 eingesetzt, der das Ventilglied 30 axial führt und einen nach hinten in das Gehäuse ragenden Vorsprung aufweist. Dieser Vorsprung wird gebildet durch Rippen 40, die auf einem Kreisumfang angeordnet sind und von dem Einsatz 38 ausgehend achsparallel in den von dem verdünnten Gehäusemantel 20 umschlossenen Raum ragen. An ihren freien Enden weisen die Rippen 40 einen radial nach aussen abgebogenen Rand 42 auf, der an dem verdünnten verformbaren Gehäusemantel 20 von innen anliegt. Die Rippen 40 sind auf diese Weise durch radialen Druck gegen den Gehäusemantel 20 nach innen biegbar.An insert 38 is inserted into the tip 14, which axially guides the valve member 30 and has a projection projecting rearward into the housing. This projection is formed by ribs 40, which are arranged on a circumference and, starting from the insert 38, project axially parallel into the space enclosed by the thinned housing jacket 20. At their free ends, the ribs 40 have an edge 42 which is bent radially outwards and abuts the thinned deformable housing jacket 20 from the inside. In this way, the ribs 40 can be bent inwards by radial pressure against the housing jacket 20.

Der Konus 36 steht unter dem Druck der Schraubendruckfeder 32 mit seiner Kegelmantelfläche in Berührung mit der Biegekante der Rippen 40, an welcher die Rippen 40 in den Rand 42 übergehen.The cone 36 is under the pressure of the helical compression spring 32 with its conical surface in contact with the bending edge of the ribs 40, at which the ribs 40 merge into the edge 42.

Die Schraubendruckfeder 32 drückt den Konus 36 nach vorn, wodurch die Rippen 40 nach aussen gedrückt werden und das Ventilglied 30 mit seiner konischen Spitze unter Druck abdichtend in der Austrittsöffnung 16 sitzt. Werden diametral amgeordnete Rippen 40 von aussen radial zusammengedrückt, so wird der Konus 36 durch die Keilwirkung seiner Kegelmantelfläche axial gegen den Druck der Schraubdruckfeder 32 nach hinten geschoben, so daß das Ventilglied 30 die Austrittsöffnung 16 freigibt und die Flüssigkeit austreten kann.The helical compression spring 32 presses the cone 36 forward, as a result of which the ribs 40 are pressed outward and the valve member 30 sits with its conical tip under pressure in the outlet opening 16. If diametrically arranged ribs 40 are radially compressed from the outside, the cone 36 is pushed axially backwards against the pressure of the helical compression spring 32 by the wedge action of its conical surface, so that the valve member 30 releases the outlet opening 16 and the liquid can escape.

In den Figuren 5 und 6 ist eine abgewandelte Ausführungsform des Gerätes der Figuren 3 und 4 dargestellt. Die Ausführungsform der Figuren 5 und 6 unterscheidet sich von der Ausführungsform der Figuren 3 und 4 nur darin, daß der mittels des Einsatzes 38 eingesetzte koaxial verformbare Vorsprung nicht durch Rippen, sondern durch einen geschlossenen Zylindermantel gebildet wird. Die Wandstärke des Zylindermantels 44 ist so gewählt, daß dieser durch radialen Druck gegen seinen nach aussen abgebogenen Rand 42 verformbar ist. Dadurch kann in gleicher Weise wie bei dem Ausführungsbeispiel der Figuren 3 und 4 der Konus 36 mit dem Ventilglied 30 durch diametralen Druck gegen den Rand 40 des Zylindermantels 44 axial nach hinten verschoben werden, um die Austrittsöffnung 16 zu öffnen.FIGS. 5 and 6 show a modified embodiment of the device of FIGS. 3 and 4. The embodiment of FIGS. 5 and 6 differs from the embodiment of FIGS. 3 and 4 only in that the coaxially deformable projection used by means of the insert 38 is not formed by ribs, but by a closed cylinder jacket. The wall thickness of the cylinder jacket 44 is selected so that it can be deformed by radial pressure against its outwardly bent edge 42. As a result, in the same way as in the exemplary embodiment in FIGS. 3 and 4, the cone 36 with the valve member 30 can be moved axially backwards by diametrical pressure against the edge 40 of the cylinder jacket 44 in order to open the outlet opening 16.

Im Gegensatz zum Ausführungsbeispiel der Figuren 3 und 4 bilden der geschlossene Zylindermantel 44 und der auf dessen Biegekante aufsitzende geschlossene Konus 36 eine vollständig dichtende Abtrennung zwischen dem Vorratsraum 12 und der Spitze 14. Wie in dem Ausführungsbeispiel der Figuren I und 2 ergibt sich somit ausser der Abdichtung der Austrittsöffnung 16 durch das Ventilglied 30 noch eine zweite Abdichtung des Vorratsraums 12 gegen die Spitze 14. Herrscht in dem Vorratsraum 12 ein Überdruck, so wirkt dieser im gleichen Sinne wie die Schraubendruckfeder 32 auf den Konus 36 und drückt diesen gegen die Biegekante des Zylindermantels 44, wobei gleichzeitig der Dichtdruck des Konus 36 gegen die Biegekante des Zylindermantels 44 und der Dichtdruck des Ventilgliedes 30 in der Austrittsöffnung 16 erhöht werden.In contrast to the exemplary embodiment in FIGS. 3 and 4, the closed cylinder jacket 44 and the closed cone 36 seated on its bending edge form a completely sealing separation between the storage space 12 and the tip 14. As in the exemplary embodiment in FIGS Sealing the outlet opening 16 by the valve member 30 a second seal of the storage space 12 against the tip 14. If there is an overpressure in the storage space 12, this acts in the same way as the helical compression spring 32 on the cone 36 and presses it against the bending edge of the cylinder jacket 44, wherein at the same time the sealing pressure of the cone 36 against the bending edge of the cylinder jacket 44 and the sealing pressure of the valve member 30 in the outlet opening 16 can be increased.
