• a first chamber having a first wall, the first chamber having a first opening,
• a first piston slidably adjacent the wall of the first chamber,

• a second piston slidably adjacent the wall of a second chamber,

wherein coupling means are provided for coupling the two pistons during delivery of the components.

It is often necessary to separate the components of a cosmetic composition contained in a container until the time of application. For example, chemical reactions between the components that are desirable when using the cosmetic composition can be avoided. It is also often necessary that incompatible or non-storable components are initially present separately in a container. In such cases, the components are stored in separate chambers of the container and conveyed via two-way valves or two-way pumps to the discharge opening, where they come into contact with each other.

Are, like the WO 2007/132 017 A1 two bags provided for the two components, it is difficult to promote the two components in a uniform defined ratio. This can be problematic, for example, in the case of pharmaceuticals, cosmetic compositions or adhesives.

Two-piston systems are also known. From the DE 20 2007 004 662 U1 For example, a container with two pistons is known, which are arranged one above the other and slide along the wall of the container. On the container a two-way pump is arranged. One The first way of the pump opens at the upper end of the container. The second path terminates in a conduit which traverses the first piston and slides along the same latter. The first component is in the space above the first piston while the second component is in the space between the first and second pistons. Also in this device, the risk of not promoting the two components in a sufficiently precise ratio, relatively large.

This disadvantage is avoided by virtue of the fact that the two pistons are mechanically coupled to one another, so that the other piston is displaced accordingly when one piston is displaced. This solution comes from the documents US 3,915,345 A respectively. DE 20 07 199 A out. In both cases, there is a central cylinder attached to a two-way valve. This is attached to a likewise cylindrical housing. A first piston slides along the inner wall of the central cylinder and thus forms a first chamber, while a second annular piston slides with its central edge along the outer wall of the central cylinder and with its outer edge along the wall of the housing, thus forming the second chamber. The two pistons are connected to each other. In the case of the document US 3,915,345 A they are connected by a double wall, which surrounds the lower edge of the central cylinder. In the first embodiment of the DE 20 07 199 A the two pistons are separated by an annular space and connected with their lower ends via a base plate. The propellant gas required for the common displacement of the two pistons is located under the base plate or under the piston.

Both at the DE 20 2007 004 662 U1 as well as at the DE 20 07 199 A or the US 3,915,345 A one of the pistons slides along the inside of the container. This container must therefore necessarily be cylindrical, so that a free choice of shape is not possible. In addition, there is a risk that the container deforms during blows. The deformation is in the part which is located below the lowermost piston, this is not a problem. However, if the deformation is in an area that has to be traversed by either piston, the likelihood of malfunction is high. Either the piston can not pass the deformation and thus none of the components can be output or the piston can pass the deformation, but deforms here, with a Leakage is caused and the components occur in the area determined for the propellant gas.

The object of the invention is thus to provide a delivery module containing at least a first and a second component of a cosmetic leave-on or rinse-off composition for application to the human body, which enables the components of the cosmetic composition before use if necessary, apply the components evenly and in a defined ratio to the human body. The dispensing module is to prevent possible malfunction in the event of deformation of the container and allow a free choice of container shape.

This object is achieved by a dispensing module of the type mentioned, in which the coupling means comprise a part connecting the first piston to the second piston, wherein the first piston, the part and the second piston form a piston unit, wherein the first chamber is annular is formed and limited in its central region by the part of the piston unit and wherein the second chamber is concentric with the first chamber and arranged above it and the first piston and / or the second piston having a piston head, initially separated from the coupling means and after filling the dispensing module with the components is irreversibly connected to the coupling means. The first chamber is filled with the first component of the cosmetic composition and the second chamber with the second component of the cosmetic composition.

As a result of the solution according to the invention, the cosmetic composition consisting of at least two components, the components of which are present in separate chambers before use, can, if required, be applied uniformly and with a defined ratio of the components to the human body. When using the dispensing module in a container with suitable dispensing means, deformation of the container no longer causes malfunction of the dispenser module. In addition, the outer shape of the container can be chosen freely, making it possible to make it more user-friendly by the grip of the container and its ergonomics are improved.

For the purposes of the present invention, cosmetic leave-on compositions are products which remain on the body and act there.

For the purposes of the present invention, cosmetic rinse-off compositions are products which are rinsed off immediately after use or after a given exposure time.

In a preferred embodiment of the invention, it is provided that the first and the second component of the cosmetic composition each have functional groups which react chemically with one another when the components are mixed. It is advantageous here that chemical reactions during storage in the delivery module are prevented, the occurrence of which is desired only when the mixture of the two components is applied. Thus, an optimal application of the mixture of components, in addition to good end product properties is possible. Such chemical reactions lead, for example, to gas release and, associated therewith, foaming of the mixture, to gel formation or else solidification of the cosmetic composition. Initiation of redox reactions is also possible by mixing the components. Color changes, the generation of haptic effects or drug release are possible desired consequences, which should occur only in the application.

Furthermore, the components can also have no functional groups which can chemically react with one another during the mixing of the components. It is advantageous that incompatible or non-storable components are mixed only during the application and thus negative effects, such as phase separations or coagulation can be avoided. In addition, when blending the components, physical effects such as changes in temperature, viscosity, color or state of aggregation, which are advantageous in use, can be caused.

It is also advantageous if the ratio of the volumes of the first and the second component is in the range between 20: 1 to 1:20, preferably between 10: 1 and 1:10 and particularly preferably between 5: 1 and 1: 5. A defined ratio of the volumes can be determined by the appropriate choice of the base areas of the pistons of the delivery module realize. The dispensing module according to the invention makes it possible to dose the cosmetic composition uniformly in the selected volume ratio.

The invention relates to a dispensing module (1) with two chambers (20, 30), which is attached to a valve (4) of a container (5), preferably a pressure vessel. Each chamber (20, 30) is provided with a piston (61, 64 and 7). Coupling means are provided for coupling the two pistons (61, 64 and 7) together after filling the chambers so that they move simultaneously. The valve (4) is preferably a two-way valve, so that the component contained in the first chamber (20) only with the exit from the valve (4) or possibly only at the exit from the valve (4) fixed outlet opening with the component of the second chamber (30) comes into contact.

The invention also relates to the dispensing module (1) mounted on a valve (4) and the container comprising a valve (4) provided with a dispensing module (1) and mounted on a housing (5).

The dispensing module (1) consists essentially of an outer shell (2), wherein in a part (21) of the same, the first piston (61) slides and the first chamber (20), of an inner shell (3), in the the second piston (64 and 7) slides and the second one Chamber (30), from coupling means (62) to the two pistons (61, 64 and 7) to be coupled together and retaining means (8) to serve as a stop for the first piston (61).

The outer shell (2) consists of a first, lower cylindrical part (21) and a second, upper cylindrical part (22) of smaller diameter. The two cylindrical parts are connected by a radial connecting wall (23). In the illustrated embodiment, the wall of the second cylindrical part, penetrating the radial wall (23), easily penetrates into the upper part of the first cylindrical part (21). This projection (25) serves as an upper stop for the first piston (61). However, it would be possible to dispense with this projection and to use the radial wall as a stop. The second cylindrical part (22) has in its upper region an annular radial shoulder (26) which is penetrated by one or more openings (261). It is thus achieved that the first jacket is tubular with openings at both ends. Channels (24) are arranged on the inside of the second cylindrical part (22). They extend over the entire height of this second part (22). The upper side of the second cylindrical part is provided with attachment means (27) with which the two-chamber delivery module (1) is attached to the two-way valve (4). These fastening means (27) comprise a crown, which is provided with locking means which can cooperate with complementary locking means on the two-way valve (4).

The inner shell (3) consists essentially of a cylindrical main part (31) whose outer diameter substantially corresponds to the inner diameter of the second cylindrical part (22) of the outer shell (2). The cylindrical body portion (31) tapers in its upper portion, preferably by forming a frusto-conical wall (32), and terminates with a cylindrical portion forming a sleeve (33). Like the outer shell (2), the inner shell also has a tubular shape with openings at both ends. The sleeve (33) has an annular radial groove (331) which is open to the outside and the bottom diameter and height of the inner diameter and the height of the annular shoulder (26) of the second cylindrical portion (22) of the outer shell (2) correspond. Therefore, the inner shell (3) can be inserted inside the upper cylindrical wall (22) of the outer shell (2) until the sleeve (33) enters the opening in the center of the annular shoulder (26) and shoulder (26). engages in the groove (331). The inner jacket (3) will be on this Way firmly fixed inside the outer shell (2). The length of the inner shell (3) is chosen so that, with the position locked in the outer shell (2), the lower end is aligned with the lower end of the upper cylindrical part (22) of the outer shell (2). The inner shell (3) serves to define with the channels (24) the outlet lines for the component contained in the first chamber (20). For this purpose, the channels (24) are dimensioned so that they open in the space which is above the frusto-conical wall (32), but below the annular shoulder (26).

The two pistons are combined in a piston unit (6). The first piston has a radial annular part (61) attached to the lower end of a cylindrical part (62). The radial annular part (61) has at its edge an axial rim (63) extending from the side of the annular part (61) facing away from the cylindrical part (62). The outer diameter of this ring (63) corresponds to the inner diameter of the first cylindrical part (21) of the outer shell. The ring (63) is provided with sealing means for sealing the piston (61) to the inside of the lower part (21) of the outer shell (2). These sealants are formed, for example, as flowable highly viscous sealants in the form of lubricants or as sealing lips (631), which consist for example of elastomeric materials. The outer diameter of the cylindrical part (62) of the piston unit (6) substantially corresponds to the inner diameter of the inner shell (3).

In this way, the first chamber (20) by an annular space between on the one hand the cylindrical lower part (21) of the outer shell and the cylindrical part of the piston unit (62) and on the other hand between the first piston (61) and the radial part (23) the outer shell connecting the lower part (21) and the upper part (22) is formed. This first chamber (20) is open to the outside via the channels (24), the space between the frusto-conical part (32) of the inner shell and the shoulder (26) of the outer shell and the openings (261).

An annular groove (611) is provided in the first piston (61) at the junction with the cylindrical part (62). The shape of this annular groove (611) is complementary to that of the projection (25) of the outer shell (2).

The first piston (61) can slide inside the lower cylindrical part (21) of the outer shell (2). In order to prevent it from escaping therefrom, it is provided that after insertion of all parts of the dispensing module (1) into the outer shell (2) at the lower end of the same retaining means (8) to fix. These retaining means (8) are formed as an axial rim (81) whose inner diameter substantially corresponds to the outer diameter of the lower cylindrical part (21) of the outer shell. This axial rim (81) extends in its lower region via an annular radial wall (82) towards the center. The retaining means (8) are attached to the lower end of the lower part (21) of the outer shell (2), for example by means of locking means. The piston (61) can thus between a first position in which it abuts against the radial wall (23) of the outer shell (2) (see Fig. 3 ) and a second position in which its lower rim (63) abuts against the annular wall (82) of the retaining means (8) (see Fig. 4 ), be moved.

The second piston (64) is formed by the top (64) of the cylindrical part (62) of the piston unit (6). This cylindrical part (62) thus serves as a coupling means, which make it possible to move the two pistons (61) and (64) simultaneously.

In the embodiment shown here, a piston head (7) is attached to the top (64). However, it would also be possible to form the piston head in one piece directly at the top.

The piston head (7) consists essentially of a radial circular wall (71), which is extended downwards by a ring (72). Sealants are provided on the outside of the ring in the form of sealing lips (721). The outer diameter of the ring (72) corresponds to the inner diameter of the cylindrical main part (31) of the inner shell (3).

Thus, the second chamber (30) is defined by the space between on the one hand the inner side of the inner shell (3) and on the other hand the frusto-conical part (32) thereof and the piston (64 or 7). He is in the upper opening of the sleeve (33) open to the outside. The head (7) of the piston (64) also serves as a sealing ring for the upper part of the first chamber (20).

The head (7) of the piston (64) is provided with locking means (722) which allow it to irreversibly lock on complementary latching means (641) which are arranged on the upper side (64) of the piston unit (6). These locking means (641, 722) are dimensioned so that a sufficiently strong pressure on the piston head (7) must be exercised so that it engages the top of the piston (64), and is preferably provided with one or more raster elements, the possible Can compensate for filling tolerances. This avoids unwanted locking, especially when storing or handling the empty dispensing modules. Further, the height of the cylindrical body portion (31) of the inner shell (and thus the height of the upper cylindrical portion (22) of the outer shell) is selected so that when the piston unit (6) is in the upper position, the first one Plunger (61) abuts the radial connecting wall (23), there is sufficient space inside the inner shell for the cylindrical part (62) and the detached, not locked piston head (7).

When assembling, first fasten the inner jacket in the outer jacket, insert the piston head (7) into the interior of the inner jacket (3), then insert the piston unit (6), inserting it as far as possible, i. until the first piston (61) abuts against the connecting wall (23). In this position, the piston head (7) is located above the upper part of the piston unit (6) without being engaged therein. The sealing means (631, 721) of the two pistons (61, 64) exert sufficient pressure on the inner wall of the respective chamber to hold the piston unit (6) and the piston head (7) in place, as long as there is no component is filled.

Such a two-chamber unit is intended to be mounted on dispensing means such as a two-way valve (4) or a two-way pump. It is also possible to provide only closing means which are opened during the dispensing process. The dispensing means may comprise dosing means such that upon actuation of the dispensing means a predetermined amount of each component is dispensed. Two-way valves are known, for example from the documents US 3,915,345A or WO 2007/132 017 A1 , The example shown here is a two-way valve of the type described in the latter document. The operation of this valve is therefore not described in detail, but only the specifics that arise in the context of its application in a two-chamber system according to the invention will be explained below.

The valve body (41) comprises a first part in the form of a downwardly bulged collar (42) and a second central part in the form of a cylindrical pin (43), wherein the part in the form of the collar (42) surrounds the peg-shaped part (43) , The collar-shaped part (42) is provided at its lower end with retaining means, which are complementary to those (27) of the outer shell (2). These holding means are dimensioned so that a tight connection between the outer shell (2) and the collar-shaped part (42) is provided. On the other hand, the pin-shaped part (43) is dimensioned so that it penetrates into the sleeve (33) of the inner shell and also ensures a tight connection. The valve is provided with two separate paths, one opening in the space between the collar (42) and the pin (43) and the other inside the pin (43). Thus, when the dispensing module (1) is mounted on the valve (4), the first chamber opens in the first path and the second chamber in the second path of the valve.

As with the two-way valve of the document WO 2007/132 017 A1 , it is possible to provide one or more openings in the body of the valve (41) so that the gas can escape via the same path as the first component when the valve is actuated. There is nothing against adding a third component to the propellant that it does not react to. The container then contains three spatially separated components during storage.

The unit consisting of the two-chamber delivery module (1) and the delivery means (4) can then be mounted in a housing (5). If the dimensions of the dispensing unit (1) and in particular the outer diameter of the outer jacket (2) and / or the diameter of the valve disc (44) of the dispensing means allow this, the dispenser module (1) can be inserted into the interior of a prefabricated housing. Otherwise, it is necessary to form the housing (5) around the dispensing module (1). This is the case with the example shown in the figures. A first advantage of the dispensing module is the fact that it is possible to use casings of any shape, in particular casings with a curved or profiled exterior. While the inside of the housing in the prior art must be exactly cylindrical to allow the piston to slide along, it is now possible to use housings of elegant or ergonomic shape. A second advantage is that deformations of the housing have no influence on the functioning of the pistons. While in the prior art the The slightest bump could hinder the sliding of the piston on the housing or its deformation could cause a leakage of the first chamber, the container provided with the dispensing module according to the invention is shock-resistant.

The FIG. 3 shows a container provided with a dispensing module (1) attached to a two-way valve (4), the two-way valve (4) being mounted on the neck of the housing (5). The gas is already introduced into the housing and exerts a pressure on both the first piston (61) and on the second piston (64) or in the present case on the piston head (7). The container can now be filled with the two components. Here, one begins by filling the first component via the first path of the dispensing means (4), then the openings (261) and the channels (24) in the first chamber (20). The piston unit (6) is pushed back by the incoming component pressing on the piston (61). If, as in the example shown, the second piston has a separate piston head (7), it remains in its initial position, ie in the upper region of the second chamber (30), while the upper part (64) of the piston unit (6) is held by the first piston (7). 61) is pressed down. An opening (642) in the top of the piston unit (6) prevents the formation of a vacuum between the fixed piston head (7) and the downwardly extending top of the piston (64). At the end of the filling operation of the first chamber (20), the rim (63) of the first piston (61) abuts against the annular radial wall (82) of the retaining means (8), as in FIG FIG. 4 shown.

The second component can now be filled via the second path of the valve (4) and the pin (43), and the sleeve (33) in the second chamber (30). The incoming component pushes the piston head (7) down. The gas in the space between the inside of the cylindrical part (62) of the piston unit is expressed via the opening (642) in the top part (64) of the piston unit. The pressure exerted by the second component on the piston head (7) is sufficient to overcome the resistance of the latching means (641, 722) and lock the piston head (7) into the piston unit (6). The two pistons (61, 64) are now coupled together and can only move simultaneously. This corresponds to the in FIG. 5 illustrated situation. It only needs a spray head on the rod (45) of the valve are plugged and possibly a protective cap can be applied. The container is ready for use. Thanks to the separate piston head (7) it is possible to fill the container with two separate filling units.

If, contrary to the embodiment shown in the present example, the second piston is formed directly on top of the piston unit (6), this side has no opening (642), the shutdown of this top, which takes over the role of the piston, air in the second chamber (30), which forms simultaneously with the first one. Therefore, the air contained in this second, already formed chamber (30) must be sucked off before the second component is filled.

It is understood that the chambers (20, 30) form only when filling the components. If a separate piston head (7) is provided for the second chamber (30), this (30) will not be formed simultaneously with the first chamber (20). On the contrary, this forms only when filling with the second component. It is therefore not necessary to provide a suction device for removing the air from the second chamber before the second component is filled.

Depending on the composition of the components used, it is necessary, after filling the first chamber and before filling the second chamber and possibly also after filling the second chamber, to clean the parts contacted by the components in order to avoid unwanted reactions between the components or their contamination to avoid.

The ratio between the initial volume of the first and second components is determined by the ratio between the area of the first (61) and second pistons (64). The dispensing module thus allows a very high precision in terms of the ratio of the initial volume of the two components. Due to the area ratio between the area of the first piston (61) and the second piston (64), it is also possible to fill the second chamber (30) with a higher pressure than the outside pressure.

It goes without saying that the first piston (61) can also be formed with a separate piston head. The piston head is then annular and filling begins with the second chamber (30) and not with the first chamber (20) when only the first piston has such a piston head. The height of the first cylindrical part (21) of the outer shell and / or the cylindrical part (62) of the piston unit must be sufficiently large to allow the piston unit (6) to fully penetrate the inner shell, abutting with its upper portion, without the annular piston head locking into the piston unit (6). When the first piston (61) has a removable piston head, it is not necessary that the second piston (64) is also provided with a separate piston head (7).

If the dispensing module (1) is used on a pressure vessel, as is the case in the example shown here, then it may be useful to the unit consisting of the dispensing unit (1) and the dispensing means (4) in the housing (5) fasten, wherein the valve plate (44) is not mounted on the housing (5). This makes it possible to fill the propellant during filling before the valve plate (44) is mounted on the housing (5). To secure the unit consisting of dispenser module / dispensers in this position (as in FIG. 2 4), a fork (9) is provided which blocks the unit so that the tip of the second cylindrical portion (22) of the outer shell abuts against the inner side of the top of the housing (5). This removable fork (9) penetrates into a groove (28), which is provided for this purpose at the top of the outer jacket (2) below the fastening means (27).

Alternatively, it is also possible to fasten the valve plate (44) to the housing (5) of the pressure vessel, then to fill the dispensing module (1) and to fill the gas via an opening in the bottom of the pressure vessel, which is subsequently closed. If the gas is filled from above, it must be ensured, for example through channels provided for this purpose, that the gas can flow to the bottom.

Suitable propellant for discharging the components are, in particular, compressed gases, such as nitrogen, oxygen and compressed air, as well as liquefied gases, such as hydrocarbons, for example butane and isopentane, dimethyl ether and fluorine hydrocarbons. However, it is also possible by means of mechanical systems, such as springs or elastic materials with restoring force, such as elastomers, to discharge the components.
