Description

The invention is directed to a device for dosing of at least two powdery or liquid to be mixed products in a mixing and / or removal container.

There is an abundance of use cases where difference products must be mixed together. A special one Res problem is posed by such components to be mixed represents, seen in itself for people handling problems have, for example, that they are toxic or corrosive or otherwise Ways are damaging.

Another problem with mixtures can be that, depending on the intended use, one of the components is to be added to the other component with a time delay, for example in order to reinforce a desired work result, as can be the case, for example, in methods for instrument disinfection in the medical field. A particularly well-suited method for this describes, for example, DE 196 51 415 of the applicant, where a method for disinfecting medical instruments by treating the instruments with a microbicidal aqueous preparation is described, which is characterized in that the following preparation is used in the manufacture of this preparation go through two steps A and B:

• A: Reacting hydrogen peroxide or peroxidic Compounds that form hydrogen peroxide in water aqueous alkaline medium with N-acyl compounds, which under these conditions are capable of generating hydrogen peroxide acylate.
• B: Lowering the pH value of the accessories contained in step A equitation and dilution, if necessary, so that for disinfection used preparation a pH between 7 and 9 before lies.

In such a method, it is particularly useful if the lowering of the pH value is delayed.

In such dosing methods, the aim is to provide the con tact of the person with the corresponding products or pro to prevent product components as much as possible or to dispense with them make and the incremental addition of the individual components in the removal container as precisely as possible.

The object of the invention is therefore to create a Vorrich device that the dosing of at least two components so undertakes that the persons concerned with product components do not come into contact with simultaneous security  the time steps required for mixing.

With a device of the type described in the introduction this object according to the invention achieved by one on the Removable receptacle bridge body with white to the container send discharge openings, switching electronics and one Device for opening at least one of the discharge openings conditions in a predeterminable time sequence.

With the device according to the invention it is possible, for. B. two different components one after the other a mix feed container, the z. B. already with the necessary Amount of water is filled as indicated in the above Literature is already described.

Appropriate configurations of the invention result from on the basis of the subclaims, it being particularly expedient if at least one storage space for one in the bridge element the components is provided with switchable release of the Exit opening after a delay after entering the first Component.

For example, first an element for disinfection used by medical devices, the appropriate component in the water of the mixing tank  be introduced, with the introduction of the first Component automatically z. B. Akti time switch electronics fourth, after a predetermined time, for example a quarter of an hour, the second component into the vessel there, for example, as described in the prior art Lowering the pH value and thus increasing the desine to achieve the result of the

One possible design is the first component to accommodate in a funnel element, it can for example a powder, this funnel element can be inserted into the first discharge opening. Erfin In accordance with this is, for example, in the discharge opening a switching element for activating the time delay circuit provided for opening the second discharge opening.

For example, the funnel element with a in the what into the first discharge opening is set, when this powder is dispensed, the Switching element activated to the second after a time delay Discharge opening and thus to release the second component.

It can also be provided that the funnel element with a bottom closure flap and an actuating element, e.g. B. a slide cam is equipped to open the  Flap when inserting the funnel element in the first off opening.

Through a possible mechanical coupling between Bodenver closing flap of the funnel element on the one hand and a loading Actuation cam on the other hand, which opens the flap position when the funnel element is inserted, it is ensured that, for. B. located in the funnel element Only then powder into the liquid underneath speed in the mixing container, if this is from the Person using the device is desired.

At this point it should be noted that the mechanical clutch can also be replaced by an electronic clutch, about that by activating a microswitch not only the time relay circuit is activated, but z. B. an electro / mechanical opening mechanism.

It may be useful to z. B. in Pa tronen or the like. To accommodate that in recesses of the Bridge element can be inserted, in the area of the A plug-in openings Separation elements for opening the cartridges are provided.

Such separators can automatically Fo  lien on the cartridges of the second component at Plug in, you can also use a pusher, approximately by means of thorns, the timing relay controls shortly before the predetermined time of delivery of the second component sticks the cartridges or the like.

With the invention it is possible in a simple manner, also on To provide at least one stirring device for the bridge element, who charge the mixing container with a stirrer or whisk strikes, for example when sprinkling in the first component or when adding the second component or further components triggering a mixture-improving stirring.

Further details, features and advantages of the invention result from the following description as well based on the drawing. This shows in:

Fig. 1 shows a simplified spatial representation of the inventive device and in

Fig. 2 shows the device according to the invention on a dosing or dispensing container also in a simplified perspective view.

The device generally designated 1 in the example shown is a bridge body 2 , which can be placed on a mixing and removal container 3 . In the Darge presented embodiment, the bridge body 2 with a container 3 facing discharge opening 4 , z. B. for a powder 5 , which the user 6 previously poured into a funnel element 7 , which is indicated in Fig. 1 tet.

The powder for z. B. two, four, six or eight liters of water, according to the indicated calibration lines, filled funnel ter 7 is inserted into the discharge opening 4 , with a funnel element 7 closing the flap opening valve by contact with an actuating shoulder 9 is opened via a slide cam 8 , which is only hinted at in the figure. At the same time, a switching edge 10 on the funnel element 7 is placed on a microswitch 11 which , when the funnel element 7 is inserted, actuates a switching electronics 12 housed in the bridge body 2 , indicated only by dashed lines, the function of which is described in more detail below.

In addition to the discharge opening 4 , in the example shown, a receptacle 14 provided with four insertion slots 13 is provided for inserting product cartridges 15 , which, for example, contain a second component, for example an activator.

Is not shown in detail, that the cartridges are that their contents can be emptied in a non-illustrated receiving space below the slots 13 for example, when inserting the cartridge 15 into the receiving slots 13 automatically perforated or cut or otherwise treated so.

If a delayed delivery of this activator is desired, the electronics 12 is set via the microswitch 11 so that, for example after five, ten or fifteen minutes, it releases the second opening (not shown in more detail) to the activator in the pool below to deliver the mixing container 3 . Optical and / or acoustic displays can be provided, as indicated on the bridge element in FIG. 1.
