Application dispenser for at least one component

 The invention relates to an application dispenser for at least one component, in particular for an adjustable dispensing and / or mixed dispenser, according to the

preamble features of claim 1.

Such application dispensers are mostly used for cosmetic articles, e.g. Lipsticks, in which a care component is mixed, used. For this purpose, static mixers are often used in which the components are introduced into a helical tube and thereby mixed. The disadvantage here, however, that a considerable

Residual volume remains in the mixer, so that, for example, when changing the metering ratio several strokes are required on the dispenser to finally reach the desired mixing ratio. Since such components can be very expensive, it is desirable that this disadvantage be largely avoided.

Furthermore, the mixture can harden in the static mixer or become inactive so that it must be replaced or the mixture of components is no longer useful.

In addition, mixing heads or so-called applicators are known in which the discharge openings are constructed needle-like, with an outlet nozzle for a component of a

Is surrounded annular gap through which exits the second component to be mixed with the adjacent component. However, the production of such applicators is relatively complicated due to the complicated tool design. DE 101 56 531 B4 further describes a deodorant roller which has a generic rotary body, in particular in the form of a ball for applying the component or liquid substance. In this case, an intermediate liquid storage below the ball is described to wet these and thus to achieve a better response during use, as well as to avoid the ball becoming dry. With oily or pasty substances, as they often prevail in care products or adhesives, the conveying effect is insufficient.

Accordingly, the invention has the object to provide an application dispenser for at least one component, wherein the above-mentioned disadvantages are avoided, in particular a defined delivery of the component and in two components improved mixing is achieved.

CONFIRMATION COPY This object is achieved by an application dispenser with the features of

Claim 1. Advantageous embodiments are the subject of the dependent claims.

Due to the proposed delivery of the component under pressure with a pump, the rotary body, in particular the ball is reliably wetted, even for substances with higher viscosity. Thus, in the ball generally used in the version located in the frame surface area, that is slightly more than the lower hemisphere safely wetted with the component, so that even at low rotation of the ball

Component is applied. The rotary body acts for the incoming from the pump outlet with pressure component as a deflection, so that the gap space is reliably filled below the ball and thus quickly the component in the manner of a

Deorollers can be applied. The pump, which generally has a suction valve on the input side and a check valve on the output side, also obstructs the path to the container of the component, so that drying out can be reliably avoided.

Additional advantages arise in the preferred embodiment with two here

Components and two pumps in the form of a dosing and / or mixing dispenser. In this case, the (common) rotational body is preferably mounted in a socket in such a way that a trough-shaped intermediate store is formed in the lower part of the ball. The pumping volume of the pump is preferably designed so that it corresponds to the volume of the buffer. Furthermore, it is expedient that the rotation body to form

Capillary gaps is guided on ribs in the socket. As a result, an overload of the pump is avoided and also causes a low discharge beyond the "equatorial plane" of the ball also, so that the upper part of the ball can also be wetted, so as to achieve a rapid application.

For easy preparation of the application dispenser, the rotary body is preferably pressed into the socket with a precise fit, so that the socket can be produced in one piece, in particular as an injection-molded part.

In the preferred embodiment as a mixed dispenser at least two supply channels for at least two components are provided below the rotary body, in particular in the region of the buffer. These are in the axial direction of the

Application dispensers aligned and can therefore be easily manufactured. In addition, the feed channels can have further subdivisions, in particular by webs, which are relatively easy to produce by injection molding. These subdivisions can also Meandering, waves or zigzags, as known from DE 20 2011 002 558 per se.

An advantage of the above type of mixed dispenser, that the feed channels are separated from each other by the partition to the rotation body, so none

Intermediate reactions can take place. By thus formed variety of

Single channels, the two or more components are then brought together on the rotating body and thus mixed intensively, since the individual outlet openings are separated only in the millimeter range and by the pressurization of

Rotation body towards an intimate mixture can be achieved. The complete separation of the components up to the exit point leaves no or only a small amount

Residual volume of mixed components.

Preferably, the outlet openings are connected to separate annular chambers, which in turn communicate with separate feed channels. Furthermore, the

Ring chambers in production terms advantageous sealed with a central plug or a ring fit, so that the construction cost is reduced. For cost-effective production, the intermediate wall is preferably formed integrally with the housing of the application dispenser, in particular as an injection molded part. Likewise, the feed channels for the components can be made in one piece with the housing as an injection molded part.

An exemplary embodiment of the application dispenser will be described below with reference to the drawing. Hereby show:

 Figure 1 is a view of an application dispenser with two rotated by 90 ° to each other cross-sections (1A and 1B).

 FIG. 2 shows two enlarged views according to FIG. 1A and 1B as well as two views of a socket of the application dispenser (2C and 2D); FIG.

 Fig. 3 is an enlarged perspective view of two feed channels; and

Fig. 4 is a perspective view corresponding to FIG. 3 with intermediate wall.

In Fig. 1, an application dispenser 1 is shown in the manner of a cylindrical pin. This has at the top a rotary body 2, in particular in the form of a ball, around the

To facilitate application of at least one component, for example for lipsticks or similar cosmetic articles, which consist of two or more components. Of the

Rotational body 2 protrudes beyond a socket 2a, which is attached to the housing 1a of the application dispenser 1. At the bottom of the housing 1a is an adjusting device 1b provided in the manner of a rotary knob, with the wedge elements (see Fig. 1A and 1B) in two components, the quantity ratio is adjustable to each other. These

Parting device is described in more detail in DE 20 2012 006 466.5 of the applicant, so that a further explanation is dispensable.

The components are conveyed out of schematically represented cartridges 1c (cf., in particular, FIG. 1 B) toward the rotary body 2 by means of a respective pump 3, wherein the two

Components (A and B) are transported separately via two feed channels 4. In addition, a plurality of outlet openings (see Fig. 4) are provided in the vicinity of the rotary body 2, wherein those for the component A are referred to herein as 4a, while those for the component B are designated by the reference numeral 4b. These mutually offset outlet openings 4a, 4b are separated by an intermediate wall 5.

In Fig. 1B, the arrangement of the cartridges 1c and container for the two components A and B can be seen, as well as the two pumps 3. In Fig. 2B, the upper portion is shown enlarged, wherein the component A via the central feed channel 4 within the Intermediate wall 5 is guided while the component B comes to an annular chamber 6 to exit along the outside of the intermediate wall 5 on the rotary body 2 under pressure. The component A thus emerges at a plurality of outlet openings 4a on the inside of the intermediate wall 5 and the component B at a corresponding number of outlet openings 4b on the radially outer side of the intermediate wall 5 (see FIG. As a result, an intensive mixing of the components is achieved directly on the rotary body 2. The separate feed channels 4a, 4b are delimited by a central plug 8 or a ring 9, so that the two components can emerge directly onto the rotary body 2 only along the fine individual channels.

In Fig. 1A at the there rotated by 90 ° with respect to FIG. B cut profile of

Application dispenser 1 only a cartridge c and a pump 3 visible. The innovation is equally applicable to this basic design with only one component pump 3, since the pressurized wetting of the rotary body 2 offers considerable advantages for the dispenser "response." In particular, the substance to be applied is practically in the "equatorial region" when the pump is actuated "the ball 2 ready to be applied by slight rotation of the ball 2 immediately.

In Fig. 2A, the upper portion of FIG. 1 is shown enlarged, wherein the

Rotary body 2 slightly displaced by the pressurization upwards and thus forms a buffer 7 below the ball. At the lowest point is here

BRU 43009 the "gap" largest, so that with two components of the product flow from the

Feed channels 4 is directed against each other (see Fig. 3). As a result, the mixing effect is further increased together with the pressurization.

In Fig. 2C is a plan view of the socket 2a without rotation body 2 is shown. Internally, six ribs 2b are formed here (compare also the corresponding perspective in FIG. 2D) in order to form narrow capillary gaps defined for the spherical surface. As a result, the overuse of the pump 3 is avoided, wherein the slight leakage of the pumped component (-n) beyond the socket 2a addition, but adhering to the ball even improves the response.

In Fig. 3, the lower part of the socket 2a is shown separately, wherein the Zuführkanale 4 can be seen for the two components. The feed channels 4 for the components A, B can be produced in one piece with the socket 2a, in particular as an injection molded part. The feed channels 4 may also have webs or subdivisions to further divide the product flow, as indicated by arrows. It is essential here that the product flow in the center of the buffer 7 is directed against each other and thus increases the mixing. This is especially true for the embodiment with intermediate wall 5, which is clearly visible in the perspective view in Fig. 4, to form the above-mentioned outlet openings 4a and 4b and to achieve the intensive mixing.
