Abstract

The spray dispenser (1) has mutually adjacent outlet openings (3a,3b) for the components, where the outlet openings stand in connection with a pump unit for the each component over a feed channel. The feed channel is straight in the preparation, particularly by injection molding and is bent at the installation in the spray dispenser. The feed channel has a single-piece formed base spring. The outlet openings are arranged close to each other. The feed channel has a masking plate which has a notch for determining the feed channel in a curved mounting position.

Description

Die Erfindung betrifft einen Sprühspender für mehrere Komponenten, insbesondere für einen einstellbaren Dosierspender, gemäß den oberbegrifflichen Merkmalen des Anspruches 1.The invention relates to a spray dispenser for a plurality of components, in particular for an adjustable dispenser, according to the preamble features of claim 1.

Derartige Sprühspender werden meist für Kosmetikartikel (z.B. Parfüms), bei denen eine Pflegekomponente beigemischt wird, für Reinigungsmittel, bei dem die Konzentration verändert wird oder Produkte, die aus mehreren Komponenten bestehen, die nicht gemeinsam gelagert werden können oder ihre Wirkung erst beim Zusammentreffen der Komponenten entwickeln, verwendet. Die Austrittsöffnungen für die zwei (oder mehr) Komponenten sollten dabei eng beieinander liegen, so dass sich die Sprühkegel überlappen und somit das Produkt vermischt z. B. auf die Haut gelangt. Nachteilig ist hierbei jedoch, dass die beiden (oder mehr) Zuführkanäle mit haarfeinen Durchlässen relativ kompliziert herzustellen sind. So sollten die Austrittsöffnungen möglichst parallel zueinander ausgerichtet sein, um eine weitgehende Überlagerung der Sprühkegel und damit Durchmischung zu ermöglichen. Die Pumpeinheiten sind jedoch bei symmetrischer Anordnung um einige Zentimeter voneinander entfernt, so dass für eine parallele Ausrichtung der Austrittsöffnungen die Zuführkanäle gebogen sein sollten. Dies verkompliziert die Herstellung jedoch zusätzlich, da die feinen Durchlässe kaum mehr exakt geformt bzw. das Bauteil kaum mehr entformt werden kann, außer dass zu besonders komplizierten Werkzeugformen gegriffen wird.Such spray dispensers are mostly for cosmetics (eg perfumes) in which a care component is mixed, for cleaning agents in which the concentration is changed or products that consist of several components that can not be stored together or their effect only at the meeting of the components develop, used. The outlet openings for the two (or more) components should be close together, so that the spray cones overlap and thus the product is mixed, for. B. gets on the skin. The disadvantage here, however, is that the two (or more) feed channels with hair-thin passages are relatively complicated to produce. Thus, the outlet openings should be aligned as parallel as possible to each other in order to allow a substantial overlay of the spray cone and thus mixing. However, the pumping units are in symmetrical arrangement by a few inches apart, so that for parallel alignment of the outlet openings, the feed channels should be bent. However, this complicates the production in addition, since the fine passages can hardly be accurately shaped or the component can hardly be demolded, except that is used to particularly complicated tool shapes.

Demzufolge liegt der Erfindung die Aufgabe zugrunde, einen Sprühspender für mehrere Komponenten zu schaffen, wobei die vorstehend genannten Nachteile vermieden werden, insbesondere ein vereinfachter, kostengünstiger und kompakter Aufbau erzielt wird.Accordingly, the invention has for its object to provide a spray dispenser for multiple components, wherein the above-mentioned disadvantages are avoided, in particular a simplified, inexpensive and compact design is achieved.

Diese Aufgabe wird gelöst durch einen Sprühspender mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved by a spray dispenser with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

Durch die vorgeschlagene Gestaltung der Zuführkanäle wird bei der Herstellung im Spritzgießverfahren oder einer ähnlichen Produktionstechnik eine exakte Ausbildung des feinen Durchlasses des jeweiligen Zuführkanals erreicht. Zudem wird insbesondere eine einfache Ausformbarkeit und ein einfacher Werkzeug-Aufbau erzielt. Weiterhin wird eine eng nebeneinander liegende Anordnung der Austrittsöffnungen sowie deren parallele Ausrichtung, wodurch sich nicht nur eine kompakte Bauweise sondern auch eine gute Überlappung der Sprühkegel und damit Durchmischung ergibt. Die Montage mit Überführung des zunächst geradlinig hergestellten Zuführkanals in die gebogene Einbauposition kann dabei sehr einfach erfolgen, insbesondere mit einer Raste und einem gewölbten Bügel.The proposed design of the feed channels an exact formation of the fine passage of the respective feed channel is achieved in the production by injection molding or a similar production technology. In addition, in particular a simple formability and a simple tool structure is achieved. Furthermore, a closely juxtaposed arrangement of the outlet openings and their parallel orientation, resulting in not only a compact design but also a good overlap of the spray cone and thus mixing results. The assembly with overpass the supply channel initially produced in a straight line in the bent installation position can be very simple, in particular with a catch and a curved bracket.

Bevorzugt sind die Austrittsöffnungen an Schiebern angeordnet, die zusammen mit dem jeweiligen Zuführkanal und Pumpenkopf sowie angrenzender Bauteile einstückig als Spritzgussteil hergestellt werden, so dass sich fertigungstechnische Vorteile mit entsprechend preisgünstiger Herstellung ergeben.Preferably, the outlet openings are arranged on slides, which are produced together with the respective feed channel and pump head and adjacent components in one piece as an injection molded part, so that there are manufacturing advantages with correspondingly inexpensive production.

Weiterhin kann an jeweiligen Pumpenkopf ein radialer Vorsprung vorgesehen sein, wiederum bevorzugt als integrales Spritzgussteil hergestellt. Dieser jeweilige Vorsprung liegt unterhalb einem Verstellteil und kann somit bei Betätigung eines Druckknopfes die entsprechende Pumpeneinheit betätigen. Dies kann simultan erfolgen, so dass bei zwei Komponenten ein Mischungsverhältnis von 1:1 ergibt. Die Betätigung kann aber durch unterschiedliche Höhenpositionierung des Vorsprungs und/oder des Verstellteils höhen- und damit versetzt erfolgen, so dass sich unterschiedliche Mischungsverhältnisse ergeben, wie die in der DE 20 2009 014 316 näher beschrieben ist. Das Verstellteil/Betätigungselement ist hierbei bevorzugt zwischen den Pumpeinheiten angeordnet, so dass eine besonders kompakte Bauweise des Sprühspenders erzielt wird. Hierzu trägt auch die nahezu bündige Anordnung des Verstellteil/Betätigungselements im Gehäuse bei.Furthermore, a radial projection can be provided on the respective pump head, again preferably produced as an integral injection-molded part. This particular projection is below an adjustment and can thus actuate the corresponding pump unit upon actuation of a push button. This can be done simultaneously, so that for two components a mixing ratio of 1: 1 results. The actuation can be done by different height positioning of the projection and / or the adjustment height and thus offset, so that different mixing ratios arise, as in the DE 20 2009 014 316 is described in more detail. The adjusting / actuating element is in this case preferably arranged between the pump units, so that a particularly compact design of the spray dispenser is achieved. This also contributes to the almost flush arrangement of the adjusting / actuating element in the housing.

In Fig. 1 ist ein Sprühspender 1 in Vorderansicht dargestellt, der zum Auftragen von Zweikomponentenprodukten verwendet wird, beispielsweise für Kosmetikartikel, die aus zwei oder mehr Komponenten bestehen. Diese Komponenten werden in hier nur schematisch dargestellten Kartuschen 1a aus gefördert bzw. mittels je einer Pumpeinheit 1 b gepumpt, wobei die beiden Komponenten getrennt über Zuführkanäle 4a und 4b (vgl. Fig. 4) zu den Austrittsöffnungen 3a und 3b zugeführt werden. Diese sind benachbart zueinander angeordnet und bevorzugt parallel zueinander ausgerichtet, um die Überlagerung der Sprühkegel zu erzielen, wenn ein Verstellteil/Betätigungselement 6 niedergedrückt wird. Der Betätigungshub ist etwa aus dem die Austrittsöffnungen 3a und 3a aufnehmenden Fenster in Fig. 1 ersichtlich.In Fig. 1 there is shown in front view a spray dispenser 1 used for applying two-component products, for example for cosmetic articles consisting of two or more components. These components are conveyed in cartridges 1 a, which are only shown schematically here, or pumped by means of a respective pump unit 1 b, wherein the two components are separated via feed channels 4 a and 4 b (cf. Fig. 4 ) are supplied to the outlet openings 3a and 3b. These are adjacent to each other arranged and preferably aligned parallel to each other to achieve the superposition of the spray cone when an adjustment / actuator 6 is depressed. The actuating stroke is approximately from the outlet openings 3a and 3a receiving window in Fig. 1 seen.

In Fig. 2 ist eine gegenüber Fig. 1 um 90° gedrehte Ansicht dargestellt, wobei neben dem Gehäuse 7 ein darin eingesetztes Verstellteil/Betätigungselement 6 ersichtlich ist (vgl. auch Fig. 4). In Fig. 3 ist eine Schnittdarstellung entlang der Schnittlinie A-A in Fig. 2 gezeigt. Hieraus ist die Anordnung der Kartuschen 1a für die beiden Komponenten ersichtlich, ebenso die beiden Pumpeinheiten 1b, die teilweise vom Gehäuse 7 umschlossen sind. Hierdurch ergibt sich bei kompakter Bauweise eine einfache Montage.In Fig. 2 is one opposite Fig. 1 shown rotated by 90 °, wherein in addition to the housing 7, an adjusting part / actuating element 6 inserted therein can be seen (see also Fig. 4 ). In Fig. 3 is a sectional view along the section line AA in Fig. 2 shown. This shows the arrangement of the cartridges 1a for the two components, as well as the two pump units 1b, which are partially enclosed by the housing 7. This results in a compact design easy installation.

In Fig. 4 ist eine Perspektivansicht mit abgenommenen oder noch nicht montierten Gehäuse 7 gezeigt. Die Komponente aus der hier vorderen Kartusche 1a wird von der Pumpeinheit 1 b und den Pumpenkopf 1 c über den Zuführkanal 4a zur Austrittsöffnung 3a gefördert. Analog gelangt die zweite Komponente B (aus der hier hinteren Kartusche) über den Zuführkanal 4b zur Austrittsöffnung 3b, die ebenso wie die andere Austrittsöffnung an einer Sichtblende 4d angeordnet ist. Die Austrittsöffnungen können auch zusätzliche Sprüheinsätze aufweisen, wodurch eine intensive Sprühwirkung der Komponenten erzielt wird. Aus dieser Perspektivansicht ist auch die kompakte Anordnung des Verstellteil/Betätigungselements 6 zwischen den beiden Pumpeinheiten 1b bzw. den darauf aufgesteckten Pumpenköpfen 1c ersichtlich, ebenso die Rändelung am Umfang des Verstellteil/Betätigungselements 6. Durch Verdrehen des Verstellteil/Betätigungselements 6 kann das Mischungsverhältnis der Komponenten verändert werden, z.B. ausgehend von einer 50:50-Dosierung zu einem 70:30-Mischungsverhältnis übergegangen werden. Dies kann in einfacher und ergonomischer Weise erreicht werden, da das Verstellteil/Betätigungselement 6 in das Gehäuse 7 bündig eingesetzt ist, wie aus der Draufsicht in Fig. 5 ersichtlich ist.In Fig. 4 is a perspective view with removed or not yet mounted housing 7 shown. The component from the front cartridge 1 a here is conveyed by the pump unit 1 b and the pump head 1 c via the feed channel 4 a to the outlet opening 3 a. Analogously, the second component B (from the rear cartridge here) passes via the feed channel 4b to the outlet opening 3b, which, like the other outlet opening, is arranged on a screen 4d. The outlet openings may also have additional spray inserts, whereby an intensive spraying effect of the components is achieved. From this perspective view, the compact arrangement of the adjusting / operating element 6 between the two pumping units 1b and the pump heads 1c plugged thereon can also be seen, as well as the knurling on the circumference of the adjusting / actuating element 6. By turning the adjusting part / actuating element 6, the mixing ratio of the components be changed, for example, proceeding from a 50:50 dosage to a 70:30 mixing ratio. This can be achieved in a simple and ergonomic manner, since the adjusting part / actuating element 6 is inserted flush into the housing 7, as from the top view in FIG Fig. 5 is apparent.

In Fig. 6 ist wiederum eine Draufsicht ohne Gehäuse 7 dargestellt, um insbesondere den Verlauf der Zuführkanäle 4a und 4b zu den entsprechenden Austrittsöffnungen 3a und 3b zu verdeutlichen. Dabei ist auch die kompakte Anordnung des Verstellteil/Betätigungselement 6 erkennbar, während in der darüber befindlichen Fig. 7 eine zugehörige Rückansicht gezeichnet ist, um die Funktion des Verstellteil/Betätigungselements 6 zu erläutern. Dieses weist nämlich zu den Pumpeinheiten 1 b hin treppenförmige Verlängerungen auf, die bevorzugt konzentrisch oder ineinander geschachtelt angeordnet sind und jeweils mit einem Vorsprung 5 am Pumpenkopf 1c zusammenwirken. Der Hier linke Vorsprung 5 ist in Radialrichtung länger und wirkt so mit dem inneren "Treppenring" zusammen, während der hier rechte Vorsprung 5 kürzer ist und mit dem äußeren "Treppenring" des Verstellteil/Betätigungselements 6 zusammenwirkt. Wenn die "Treppenring" um die Hochachse verdreht werden, ergibt sich (beim Drücken des Verstellteil/Betätigungselements 6) eine zeitverzögerte Betätigung der Pumpeinheiten 1 b (außer bei der Mittelstellung mit zeitgleicher Pumpenbetätigung) und damit ein unterschiedliches Mischungsverhältnis.In Fig. 6 again a plan view is shown without housing 7, in particular to illustrate the course of the feed channels 4a and 4b to the corresponding outlet openings 3a and 3b. In this case, the compact arrangement of the adjusting / actuating element 6 can be seen while in the overlying Fig. 7 an associated rear view is drawn to explain the function of the adjusting / actuating element 6. This has namely to the pumping units 1 b out stepped extensions, which are preferably arranged concentrically or nested and each cooperate with a projection 5 on the pump head 1c. The here left projection 5 is longer in the radial direction and thus interacts with the inner "staircase", while the here right projection 5 is shorter and cooperates with the outer "stairs" of the adjustment / operating element 6. If the "stair ring" are rotated about the vertical axis, there is a time-delayed actuation of the pump units 1 b (when pressing the adjusting / operating element 6) (except for the center position with simultaneous pump actuation) and thus a different mixing ratio.

In Fig. 8 und 9 ist die hier wesentliche Gestaltung der Zuführkanäle 4a, 4b am Beispiel des Zuführkanals 4b dargestellt. Fig. 8 zeigt hierbei den Herstellungszustand, während Fig. 9 den Montage- oder Einbauzustand zeigt. Die Bezugszeichen sind hierbei analog eingetragen, wobei dies entsprechend für den Zuführkanal 4a gilt. Links oben ist die Austrittsöffnung 3b und der Vorsprung 5 ersichtlich. Rechts daneben ist (um 90° gedreht) eine Stegfeder 4c erkennbar, die unterhalb des Zuführkanals 4b (vgl. darunter befindliche Perspektivansicht) einstückig daran angeformt ist, insbesondere im Spritzgießverfahren. Gleiches gilt auch für die Sichtblende 4d, die zudem eine Raste 4f aufweist, wie dies in der Draufsicht links daneben dargestellt ist. Hierdurch kann der bei der Herstellung geradlinige und damit gut entformbare Zuführkanal 4b zu einen Bügel 4e hin gebogen werden und dort mit der Raste 4f verriegelt werden (vgl. die analoge Darstellung in Fig. 9, links unten). Die in Fig. 8 und 9 gezeigten Bauteile bilden damit ein einziges, kostengünstig herzustellendes Spritzgussteil, das zudem einfach zu montieren ist.In 8 and 9 is the here essential design of the feed channels 4a, 4b shown on the example of the feed channel 4b. Fig. 8 shows here the state of manufacture, while Fig. 9 shows the mounting or installation state. The reference numerals are entered analogously, and this applies correspondingly to the feed channel 4a. Top left, the outlet opening 3b and the projection 5 can be seen. To the right of this, a bar spring 4c can be seen (rotated by 90 °), which is formed integrally thereon below the feed channel 4b (see below perspective view), in particular by injection molding. The same applies to the screen 4d, which also has a notch 4f, as shown in the plan view left next to it. As a result, the feed channel 4b, which is rectilinear and therefore easy to demould during production, can be bent to form a bracket 4e and locked there with the catch 4f (compare the analogous representation in FIG Fig. 9 , bottom left). In the 8 and 9 shown components thus form a single, inexpensive to manufacture injection molded part, which is also easy to install.
