Abstract

A rod-shaped device for applying liquid or pasty materials, consisting of a casing (1) containing the material, one or several outlet orifices provided at the top end of the casing for the material and one rotary knob (6) arranged at the bottom end of the casing, with which knob a non-rotatable piston (3), located in the casing (1), can be moved towards the top end of the casing by means of a rod (4). With the aid of an engagement means (12, 13) which can be overrun, located between the casing and the rotary knob, it is possible to dispense a specific quantity of material at each rotation or fraction thereof. A particularly simple embodiment of the device can be achieved if, between the rotary knob and the piston-carrying rod a hollow cylindrical neck section (7) is provided, the diameter of which is smaller than the rotary knob (6) but larger than the rod (4), and if a ring (8) is so arranged on the neck section (7) that the latter can indeed be rotated, but not moved axially, and if the ring (8) is linked to the casing (1) so as not to rotate, and the engagement means (12, 13) are operative between the ring (8) on the one hand and the neck section (7) on the other. A plug (14) which can be inserted into the end of the rotary knob ensures that the clamping of the ring (8) in the casing (1) is reinforced and that the recoil of the engagement lug (12) is limited.

Description

Die Erfindung betrifft eine stiftförmige Vorrichtung zur Applikation flüssiger oder pastöser Massen, bestehend aus einer die Masse enthaltenden Hülse, einer oder mehrerer am Kopfende der Hülse vorgesehenen Austrittsöffnungen für die Masse und einem am Fußende der Hülse angeordneten Drehknopf, mit dem über eine Spindel ein in der Hülse verdrehsicher geführter Kolben in Richtung auf das Kopfende der Hülse bewegbar ist.The invention relates to a pen-shaped device for applying liquid or pasty masses, consisting of a sleeve containing the mass, one or more outlet openings provided at the head end of the sleeve for the mass and a rotary knob arranged at the foot end of the sleeve, with which a via a spindle in the Sleeve rotatably guided piston is movable in the direction of the head end of the sleeve.

Derartige Vorrichtungen haben den Nachteil, daß die Menge der jeweils für den Verbrauch benötigten Masse nur schwer dosierbar ist und es vom Geschick des Benutzers abhängt, wieviel Masse bei Betätigung des Dreh-Hubmechanismus austritt. Daher hat man solche Vorrichtungen auch bisher im wesentlichen nur für in sich weitgehend formbeständige Massen verwendet, z.B. für Klebstoff oder Lippenstiftmasse, weil dort bei einer zu starken Drehung noch eine Korrekturmöglichkeit besteht, indem der Drehknopf wieder etwas zurückgedreht wird. Eine solche Korrektur ist jedoch ausgeschlossen, wenn die Konsistenz der Masse cremig-weich oder sogar flüssig ist, was für viele kosmetische Massen zutrifft. Aus diesem Grunde werden cremig-weiche Kosmetika, wie z.B. Rouge, Lidschatten u. dgl. mit Hilfe eines Tupfers oder eines entsprechenden Applikatormaterials, das einen gewissen Vorrat an Masse aufnehmen und dann in der gewünschten Menge auf die Haut übertragen kann, einem tegelartigen Behältnis entnommen und appliziert.Devices of this type have the disadvantage that the amount of the mass required in each case for consumption is difficult to dose and it depends on the skill of the user how much mass emerges when the rotary-lifting mechanism is actuated. For this reason, such devices have hitherto been used essentially only for masses which are largely dimensionally stable, for example for glue or lipstick mass, because if there is too much rotation there is still a possibility of correction by turning the rotary knob back a little. However, such a correction is impossible if the consistency of the mass is creamy-soft or even liquid, which is true for many cosmetic masses. For this reason, creamy-soft cosmetics such as blush, eyeshadow and the like. The like. With the help of a swab or an appropriate applicator material that absorb a certain amount of mass and then in the desired amount on the skin transferred, removed from a tegel-like container and applied.

Bei flüssigen kosmetischen Massen, z.B. bei Wimperntusche, wird ein an seinem Ende mit einer Riffelung oder einer Bürste versehener Applikatorstab vor dem Auftragen in die flüssige Masse eingetaucht, wobei ebenfalls Probleme hinsichtlich einer genauen Dosierung bestehen, weil Länge und Dichte der Wimpern nicht immer gleich sind, aber immer nur die gleiche Menge der Flüssigkeit am Applikatorstab haften bleibt.In the case of liquid cosmetic compositions, for example mascara, an applicator rod provided with a corrugation or a brush at its end is dipped into the liquid composition before application, and there are also problems with precise dosing because the length and density of the eyelashes are not always the same , but only the same amount of liquid sticks to the applicator stick.

Aus der US-A-3 002 517 ist ein kosmetischer Applikator bekannt, bei dem zwischen der Hülse und dem Drehknopf überfahrbare Rastmittel vorgesehen sind, die pro Umdrehung oder Bruchteilen einer Umdrehung wirksam werden. Durch den schrittweise betätigbaren Hubmechanismus ist eine genaue Dosierung der für die Auftragung benötigten Menge der Masse möglich, wobei die Menge durch die mechanische Ausbildung des Hubmechanismus genau und reproduzierbar definiert werden kann. Durch mehrfache Betätigung des Hubmechanismus kann die Menge der austretenden Masse dem jeweiligen Bedarf angepaßt werden. Dies führt zu einem sehr sparsamen Verbrauch. Dieser bekannte Applikator besteht aus einer Vielzahl von Einzelteilen, deren Herstellung und Montage aufwendig ist.A cosmetic applicator is known from US-A-3 002 517, in which latching means which can be moved over between the sleeve and the rotary knob are provided and which take effect per revolution or fractions of a revolution. The step-by-step lifting mechanism enables precise metering of the amount of mass required for the application, the amount being able to be defined precisely and reproducibly by the mechanical design of the lifting mechanism. By repeated actuation of the lifting mechanism, the amount of the emerging mass can be adapted to the respective need. This leads to very economical consumption. This known applicator consists of a large number of individual parts, the manufacture and assembly of which is complex.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der zuletzt genannten Art zu schaffen, die konstruktiv einfach und leicht montierbar ausgebildet ist.The invention has for its object to provide a device of the latter type, which is structurally simple and easy to assemble.

Die gestellte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß zwischen dem Drehknopf und der den Kolben tragenden Spindel ein hohlzylindrischer Halsabschnitt angeordnet ist, dessen Durchmesser kleiner als der Drehknopf aber größer als der Durchmesser der Spindel ist, wobei auf dem Halsabschnitt ein Ring so angeordnet ist, daß der Halsabschnitt in ihm zwar drehbar aber nicht axial verschiebbar ist, wobei ferner der Ring drehsicher mit der Hülse verbunden ist und die Rastmittel zwischen dem Ring einerseits und dem Halsabschnitt andererseits wirken.The object is achieved according to the invention in that a hollow cylindrical neck portion is arranged between the rotary knob and the spindle carrying the piston, the diameter of which is smaller than the rotary knob but larger than the diameter of the spindle, wherein a ring is arranged on the neck section such that the neck section is rotatable but not axially displaceable in it, the ring also being connected to the sleeve in a rotationally secure manner and the latching means acting between the ring on the one hand and the neck section on the other.

Dabei ist es zweckmäßig, daß zwischen der Spindel und dem Halsabschnitt ein Konus vorgesehen ist, dessen Durchmesser bis auf mindestens den Innendurchmesser des Rings zunimmt und an der Übergangsstelle zum Halsabschnitt sprunghaft abfällt. Auf diese Weise kann der Ring über die Spindel und den Konus hinweg auf den Halsabschnitt aufgeschoben werden, wo er zwischen dem Drehknopf und dem Konus einrastet, so daß er axial nicht mehr bewegt werden kann.It is expedient that a cone is provided between the spindle and the neck portion, the diameter of which increases to at least the inside diameter of the ring and drops abruptly at the transition point to the neck portion. In this way, the ring can be pushed over the spindle and the cone onto the neck section, where it engages between the rotary knob and the cone, so that it can no longer be moved axially.

Vorzugsweise werden die Rastmittel durch einen oder mehrere axiale Schlitze oder Vertiefungen in dem Halsteil und einer federnden Rastnase am Ring gebildet. Die Rastnase kann dabei aufgrund ihrer Federwirkung mit einem einwärts weisenden Rastvorsprung in den oder die Schlitze einfallen und nach Überwindung eines Widerstands auch wieder aus der Rastung herausgedreht werden.The locking means are preferably formed by one or more axial slots or depressions in the neck part and a resilient locking lug on the ring. Due to its spring action, the latching lug can fall into the slot or slots with an inward-pointing latching projection and, after overcoming resistance, can also be unscrewed from the latching again.

Zweckmäßigerweise ist der Ring an seinem einen Ende mit einem Flansch versehen, und sein Außendurchmesser ist so bemessen, daß der auf den Halsteil aufgerastete Ring bis an den Flansch in das Fußende der Hülse einschiebbar ist und in dieser durch Klemmung gehalten bleibt. Diese Maßnahme macht die Montage einfach, denn der Ring braucht nur von hinten in die Hülse eingeschoben zu werden, was ohne Werkzeug geschehen kann.The ring is expediently provided with a flange at one end, and its outer diameter is dimensioned such that the ring which is snapped onto the neck part can be pushed as far as the flange into the foot end of the sleeve and remains held in this by clamping. This measure makes assembly easy because the ring only needs to be inserted into the sleeve from behind, which can be done without tools.

Eine Weiterbildung der Erfindung besteht darin, daß in das Ende des Drehknopfes ein Stopfen einsteckbar ist, der den Drehknopf verschließt, und dessen vorderes zylindrisches Ende einerseits so lang bemessen ist, daß es in den hohlzylindrischen Halsabschnitt hineinragt, und welches andererseits im Durchmesser etwas größer als der Innendurchmesser des Halsabschnittes ist. Neben seiner Funktion als Verschlußelement, das noch durch entsprechende Farbgestaltung auf den Inhalt der Vorrichtung hinweisen kann, hat der Stopfen noch eine weitere wichtige Funktion, nämlich die Aufweitung des Halsabschnittes, die zweierlei bewirkt, nämlich einerseits, daß die Klemmung des Rings in der Hülse verstärkt wird und andererseits daß die Rastnase vorgespannt wird, so daß sie sehr deutlich fühlbar und ggfs. auch akustisch hörbar in den oder die axialen Schlitze oder Vertiefungen in dem Halsteil einfällt.A further development of the invention is that a plug can be inserted into the end of the rotary knob, which closes the rotary knob, and the front cylindrical end of which is dimensioned on the one hand so long that it projects into the hollow cylindrical neck section, and which on the other hand is slightly larger in diameter than the inside diameter of the neck section. In addition to its function as a closure element, which can also indicate the content of the device by appropriate color design, the stopper has another important function, namely the expansion of the neck section, which does two things, namely on the one hand that the clamping of the ring in the sleeve reinforces is and on the other hand that the locking lug is biased so that it is felt very clearly and if necessary also acoustically audible in the or the axial slots or depressions in the neck part.

Abgesehen von dem in das Stirnende der Hülse einsetzbaren Applikatorkopf und der Verschlußkappe besteht die gesamte Vorrichtung nur aus vier Teilen, die schnell und ohne Werkzeug ineinandergesteckt und zu einer Einheit zusammengefügt werden können.Apart from the applicator head and the sealing cap, which can be inserted into the front end of the sleeve, the entire device consists of only four parts, which can be plugged into one another quickly and without tools and assembled into a unit.

Die in Fig. 1 gezeigte Vorrichtung besteht aus einer Hülse 1, die zur Aufnahme der aufzutragenden Masse dient. Am vorderen Ende der Hülse 1 ist ein Applikatorkopf 2 angebracht, der innen hohl ist, und dessen Hohlraum mit der in der Hülse 1 befindlichen Masse in Verbindung steht. Vom Hohlraum des Applikatorkopfes verlaufen eine oder mehrere nicht dargestellte Öffnungen nach außen, so daß die Masse aus der Hülse auf die Außenfläche des Applikatorkopfes 2 befördert werden kann, um sie dann auf die Haut aufzutragen. Der Applikatorkopf ist hier nur als eine mögliche Ausführungsform dargestellt und bildet keinen Bestandteil der vorliegenden Erfindung.The device shown in Fig. 1 consists of a sleeve 1, which serves to hold the mass to be applied. At the front end of the sleeve 1, an applicator head 2 is attached is hollow on the inside, and its cavity communicates with the mass in the sleeve 1. From the cavity of the applicator head, one or more openings (not shown) run outwards, so that the mass can be conveyed out of the sleeve onto the outer surface of the applicator head 2 in order to then apply it to the skin. The applicator head is shown here only as a possible embodiment and does not form part of the present invention.

Zum Transport der Masse aus der Hülse 1 in den Applikatorkopf 2 dient ein Kolben 3, der auf einer Spindel 4 sitzt und im gefüllten Zustand der Hülse 1 die in Fig. 1 dargestellte Lage einnimmt. Der Kolben 3 ist in der Hülse 1 kraft- oder formschlüssig geführt, so daß er sich nicht dreht, wenn die Spindel 4 gedreht wird. Die Drehung der Spindel 4 wird durch einen Drehknopf 6 bewirkt, der über einen hohlzylindrischen Halsabschnitt 7 und einen Konus 5 mit der Spindel 4 verbunden ist. Der Durchmesser des Halsabschnittes 7 ist dabei kleiner als der Drehknopf aber größer als der Durchmesser der Spindel. Der Konus 5 fällt an seiner Übergangsstelle zum Halsabschnitt sprunghaft ab und bildet dadurch eine Schulter.A piston 3, which sits on a spindle 4 and, when the sleeve 1 is filled, assumes the position shown in FIG. 1 for transporting the mass from the sleeve 1 into the applicator head 2. The piston 3 is guided in the sleeve 1 non-positively or positively so that it does not rotate when the spindle 4 is rotated. The rotation of the spindle 4 is effected by a rotary knob 6, which is connected to the spindle 4 via a hollow cylindrical neck section 7 and a cone 5. The diameter of the neck portion 7 is smaller than the knob but larger than the diameter of the spindle. The cone 5 drops off suddenly at its transition point to the neck section and thereby forms a shoulder.

Auf den Halsabschnitt 7 ist, bevor der Kolben 3 in Position auf der Spindel 4 gebracht wird, ein Ring 8 aufschiebbar, der an seinem in Fig. 1 rechten Ende mit einem Flansch 9 versehen ist. Der Innendurchmesser des Rings 8 ist dabei so bemessen, daß er auf dem Halsabschnitt locker sitzt, so daß dieser in ihm drehbar ist, jedoch ist der Durchmesser des Konus 5 an der Übergangsstelle zum Halsabschnitt 7 so bemessen, daß der Ring 8 darübergeschoben werden kann aber dann hinter dem Konus einrastet, so daß er in axialer Richtung festgelegt ist. Der Außendurchmesser des Rings 8 ist so bemessen, daß er stramm in die Hülse 1 paßt, in die er zusammen mit der Spindel 4 und dem Drehknopf eingeschoben werden kann. Gemäß Fig. 2 sind im Ring 8 zwei axiale Einschnitte 10 vorgesehen, zwischen denen eine federnde Rastnase 11 gebildet wird, die einen einwärts weisenden Rastvorsprung 12 aufweist. Der Rastvorsprung 12 wirkt mit einem oder mehreren Schlitzen 13 im Halsabschnitt 7 zusammen, in die der Rastvorsprung 12 bei Betätigung des Drehknopfes 6 einfällt. Es kann ein einziger Schlitz 13 oder eine Vertiefung vorgesehen werden, so daß pro Umdrehung des Drehknopfes 6 nur einmal eine Rastung erfolgt, jedoch können auch mehrere Schlitze oder Vertiefungen 13 vorgesehen werden, so daß eine Rastung schon bei Bruchteilen einer Umdrehung erfolgt.Before the piston 3 is brought into position on the spindle 4, a ring 8 can be pushed onto the neck section 7, which ring is provided with a flange 9 at its right end in FIG. 1. The inner diameter of the ring 8 is dimensioned such that it sits loosely on the neck section so that it can be rotated in it, but the diameter of the cone 5 at the transition point to the neck section 7 is dimensioned such that the ring 8 can be pushed over it then clicks into place behind the cone so that it is fixed in the axial direction. The outer diameter of the ring 8 is dimensioned so that it fits tightly into the sleeve 1, into which it can be inserted together with the spindle 4 and the rotary knob. 2, two axial incisions 10 are provided in the ring 8, between which one resilient Locking lug 11 is formed, which has an inwardly facing locking projection 12. The locking projection 12 interacts with one or more slots 13 in the neck section 7, into which the locking projection 12 engages when the rotary knob 6 is actuated. A single slot 13 or a recess can be provided, so that there is only one detent per revolution of the rotary knob 6, but several slots or recesses 13 can also be provided, so that a detent takes place at a fraction of a revolution.

Der Drehknopf 6 ist ebenfalls hohl ausgebildet, und in das Ende des Drehknopfes ist ein Stopfen 14 einsetzbar, der einerseits den Drehknopf nach außen abschließt, und der andererseits ein zylindrisches Ende 15 besitzt, das so lang bemessen ist, daß es in den hohlzylindrischen Halsabschnitt 7 hineinragt. Darüberhinaus ist das zylindrische Ende im Durchmesser etwas größer als der Innendurchmesser des Halsabschnitts 7, wodurch erreicht wird, daß der Halsabschnitt geringfügig aufgeweitet wird, was wiederum zur Folge hat, daß ein radialer Druck auf den Ring 8 ausgeübt wird, der die Klemmung in der Hülse 1 verstärkt, und der außerdem die Rückfederung der Rastnase 11 begrenzt, so daß bei der Betätigung des Drehknopfes 6 die Wahrnehmbarkeit der Rastung erhöht wird und auch zusätzlich akustisch hörbar gemacht werden kann.The knob 6 is also hollow, and in the end of the knob a plug 14 can be inserted, which on the one hand closes the knob to the outside, and on the other hand has a cylindrical end 15 which is dimensioned so long that it is in the hollow cylindrical neck portion 7th protrudes. In addition, the cylindrical end is slightly larger in diameter than the inside diameter of the neck portion 7, which causes the neck portion to widen slightly, which in turn results in radial pressure being exerted on the ring 8 which causes the clamping in the sleeve 1 reinforced, and which also limits the resilience of the locking lug 11, so that the perceptibility of the locking is increased when the rotary knob 6 is actuated and can also be made acoustically audible.

Die Montage geschieht in folgender Reihenfolge: Zunächst wird der Ring 8 über die Spindel 4 und den Konus 5 auf den Halsabschnitt 7 aufgerastet. Dann wird der Kolben 3 auf die Spindel 4 bis in die in Fig. 1 dargestellte Endlage aufgeschraubt. Anschließend wird diese vormontierte Einheit in das hintere Ende der Hülse eingesteckt. Dann wird der Stopfen 14 eingesetzt, die kosmetische Masse eingefüllt und der Applikatorkopf 2 angebracht. Alle diese Montagevorgänge sind einfach durchführbar, ohne daß dafür spezielle Werkzeuge benötigt werden.The assembly takes place in the following order: First, the ring 8 is snapped onto the neck section 7 via the spindle 4 and the cone 5. Then the piston 3 is screwed onto the spindle 4 up to the end position shown in FIG. 1. Then this pre-assembled unit is inserted into the rear end of the sleeve. Then the stopper 14 is inserted, the cosmetic mass is poured in and the applicator head 2 is attached. All of these assembly processes can be carried out easily without the need for special tools.
