Abstract

Dosing dispenser for several components, each filled in a cartridge and are conveyed by means of an actuating element to a dosing, wherein the cartridges are guided in a housing and each having an extension to the actuating element out, which is aligned along the side surface of the cartridge, characterized in that the extension (6) is formed on the side surface (2a), leaving the bottom region (2b) of the cartridge (2) free.

Description

The invention relates to a metering dispenser for a plurality of components, which are each filled in a cartridge and are conveyed by means of an actuating element to a dosing, wherein the cartridges are guided in a housing and each having an extension to the actuating element out, which aligned along the side surface of the cartridge is.

Such a dispenser is from the WO 00/09270 A1 or in a similar way from the U.S. Patent 6,464,107 known, wherein two or more of such cartridges are inserted in a housing, so that they are displaced by an adjustable actuating element. The cartridges in this case have so-called suction valves, so that after releasing the actuator, the cartridges return under spring pressure to its original position, but the components are sucked out of the cartridges and further promoted to the dosing. Here, the actuating element is preferably designed to be adjustable, so that a variable metering ratio can be achieved. This is useful, for example, in comparison to a fixed metering ratio, when two components with different sun protection factors are filled into the cartridges for use in sun protection. As a result, the desired sun protection factor can be set variably. However, other components for industrial use (eg, adhesives) or from the cosmetics industry (eg, different hair tints) are also possible as components for the use of such a dosing dispenser.

However, the metering dispenser described in the above documents is still to be improved in terms of manufacturing costs, especially for mass production in the cosmetics industry or the like. Such customers usually want the delivery of the dosing dispenser for filling the corresponding components in their own production facilities, for example, to adapt the recipe of the individual components to each other or for quality assurance. After filling in the production facility with the respective component, however, a so-called drag piston must still be inserted into the cartridge in order to allow the abovementioned function of the suction valves. In the above writings, a lid is placed on the underside of the cartridge, which has a pin-like extension to the actuator out. However, this attachment of a cartridge cover is time-consuming and expensive in large-scale production.

Accordingly, the invention has for its object to simplify such a dispenser in terms of manufacturing costs.

This object is achieved by a metering dispenser with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

By the proposed attachment of the extension of the bottom portion of the cartridge remains completely free, so that the respective component and then the drag piston can be easily filled or inserted into the cartridge. The fixation of further components (eg a cover on the cartridge) is thus no longer necessary, resulting in a considerable reduction of the production costs. This applies in particular to dosing dispensers with more than two components and the corresponding number of cartridges.

Advantageously, the extension is integrally formed with the cartridge, so molded in the usual injection molding process. As a result, the extension is formed with the release of the bottom area on the side surface. If the cartridge is preferably oval in cross-section, the tubular extension is integrally formed on one of the flattened sides of the oval cartridge, preferably at an angle of approximately 45 ° with respect to the central axis. In order to prevent jamming of this laterally mounted extension during actuation, this is preferably used in a sleeve-shaped guide in the housing. This guide can be arranged directly in the housing or in the later patch actuator. In the case of two cartridges, each having one extension, two sleeve-shaped guides are thus provided, which are preferably offset by 180 ° from one another. As a result, both cartridges can be designed identical, which allows a simplification of production.

Hereinafter, an embodiment of the dosing dispenser will be explained and described with reference to the drawing. Hereby show:

1 a cross-sectional view through a metering dispenser;

2 a 90 ° offset cross-sectional view of the dosing dispenser acc. 1 ;

3 a perspective view of a cartridge for a dispenser; and

4 a perspective view of a housing for two cartridges for use in a dosing dispenser acc. 1 and 2 ,

In 1 is a dosing dispenser 1 shown in the basic structure of the aforementioned U.S. Patent 6,464,107 broadly corresponds, namely insofar as two cartridges 2 are provided, which in a tubular housing 5 are used. Likewise, those in the cartridges 2 located components by pressure on the bottom side actuator 3 to an upper dosing head 4 pumped or promoted. This is done by moving the cartridges 2 to the dosing head 4 down, taking on the cartridges 2 mounted suction pumps, as also described in principle in the aforementioned US Patent. This will bring the two components to a central mixing tube here 4a of the dosing head 4 and are discharged there, for example, a two-component adhesive on a splice.

In 2 is a 90 ° rotated view of the dosing dispenser 1 represented, wherein the same components are provided with the same reference numerals. From this is in particular a to the actuator 3 leading extension 6 on the side surface 2a the cartouche 2 seen. This extension 6 is preferred on the side surface 2a integrally formed, in particular by injection molding. Thus, when the actuator 3 is pressed, the cartridge is 2 over the extension 6 pushed up so that the metering valve described above is actuated. After releasing the disc-shaped actuator 3 returns the cartridge 2 back to the starting position, wherein the corresponding component is nachgefördert via the suction valve. This is a so-called drag piston 2c in the cartouche 2 used, so that with increasing removal of the component of the drag piston inside the cartridge 2 moves upwards, as in 1 shown.

In 3 is the cartouche 2 with the molded extension 6 shown in perspective and that from the top, where the metering valve when inserted into the housing 5 locks. At the bottom, near the extension 6 is molded, is the cartridge 2 open for filling, leaving after filling the component, taking the cartridge 2 "Overhead" (see the position in 4 ) is arranged, and also the drag piston 2c can be used in a simple manner.

In 4 is the tubular housing 5 from the bottom, so essentially shown in the filling position. Here, the housing is used 5 for holding two oval cartridges 2 as well as from the oval cutouts 8th is apparent. Between these recesses 8th are sleeve-shaped guides 7 provided in which the extensions 6 the cartouche 2 are used. This will when pressure on the actuator 3 an exact guidance of the extension 6 reached. In addition, the two oval recesses allow 8th in the immediate vicinity of the two guides 7 the trouble-free filling of the respective component and then the insertion of the drag piston 2c into the cartouche 2 through these cutouts. Finally, then only needs the actuator 3 on the case 5 be placed on top of the dosing dispenser 1 to finish. This can be done in a simple and cost-effective manner in assembly line production.
