Definitions
- the invention relates to a liquid dispenser for dispensing a liquid, in particular a pharmaceutical or cosmetic liquid.
- the invention relates in particular to a liquid dispenser which is designed as a drip dispenser.
- the liquid dispensers that are the subject of the invention are characterized in that the liquid to be dispensed is not already ready for dispensing when the dispenser is in the delivery state, but instead a mixing process of at least two starting media is required first.
- a liquid dispenser of this type therefore has at least two separate media chambers which are connected to one another prior to discharge, so that the at least two starting media can mix with one another and thereby form a mixed liquid which can then subsequently be discharged.
- the object of the invention is to provide a liquid dispenser which ensures a particularly high degree of homogeneity of the liquid mixed through and is easy and intuitive to use.
- a drop dispenser for dispensing cosmetic or pharmaceutical liquids in the form of individual drops is proposed according to a first aspect of the invention, which has a media reservoir with a first media chamber and a second media chamber, which are isolated from one another in a delivery state for separate storage of two media. Two different media are stored in the media chambers, at least one of which is in liquid form.
- the second medium can also be liquid or else be present in a form that can be dissolved by liquid, in particular as a powder or granules.
- the media chambers can be connected to one another by the user in order to thereby generate a mixed liquid, ie a liquid that is created by the mixing of both media.
- the drop dispenser has a discharge opening through which the mixed liquid can be discharged.
- This discharge opening is preferably associated with a discharge valve, which already opens at a low overpressure in the mixed liquid compared to the environment, in particular at an overpressure of not more than 2 bar, preferably at an overpressure of not more than 1 bar.
- Such an opening at a low overpressure is advantageous in order to enable the formation of drops and to prevent the risk of the mixed liquid being discharged as a jet of liquid.
- the droplet dispenser has a droplet-forming contour downstream of the discharge opening, so that the mixed liquid can collect there and then be released from the droplet-forming contour in the form of a drop.
- the droplet formation contour can have a droplet formation surface which surrounds the discharge opening and which in particular is preferably delimited on the outside by a tear-off edge.
- the drop dispenser has a pump device between the media reservoir and the discharge opening, this pump device having a volumetrically variable pump chamber for conveying mixed liquid.
- the pump chamber On the inlet side, the pump chamber has an inlet valve that opens in the event of negative pressure in the pump chamber and, on the outlet side, an outlet valve that opens in the event of excess pressure in the pump chamber.
- the pump device is designed to convey the previously mixed liquid. After the first and second media chambers are connected to each other, the media contained therein mix and thus form the mixed liquid. It is usually envisaged that the user will shake the dispenser after connecting the media chambers together to achieve a homogeneous blending.
- the homogeneity of the liquid can be improved by subsequently conveying the already mixed liquid by means of a pump device.
- the pump device leads to an increase in homogeneity by applying pressure to the mixed liquid. It is of particular advantage if the pump chamber has the inlet and the outlet on the same side of the pump chamber, since this achieves a deflection of the liquid flow, which is useful for achieving a high degree of homogeneity.
- the pump device is preferably designed to convey only a comparatively small amount of liquid when the pump is actuated, preferably less than 100 ml, in particular less than 50 m ⁇ . This reduces the risk of too much liquid being conveyed to the discharge opening due to excessively forceful actuation that the desired droplet formation does not take place here.
- a liquid dispenser for dispensing cosmetic or pharmaceutical liquids is proposed.
- this liquid dispenser is preferably designed as a drip dispenser of the type described above.
- the liquid dispenser according to the second aspect of the invention has a media storage for storing media prior to discharge.
- the media reservoir has a first media chamber and a second media chamber in the type already described, which are provided to hold different media, in particular to hold two different liquids or one liquid and one medium in liquid-dissolvable form, in particular a powder or Granules.
- the media chambers are isolated from one another and can be connected to create a blended liquid.
- another preferred form for storing a medium is in the form of a solid.
- the medium is formed by a fine, porous solid structure, which remains if the moisture previously introduced with the solid contained therein is removed before the medium chamber is closed.
- the liquid dispenser has a discharge opening through which the mixed liquid can be discharged from the media reservoir.
- it can be a discharge opening which is designed for dispensing drops.
- other configurations of a discharge opening are also possible, for example those which discharge the mixed liquid in the form of an atomized spray mist or in the form of an unatomized jet.
- a pumping device for pumping the liquid from the media reservoir to the discharge opening, which has a pumping chamber with an inlet valve on the inlet side and an outlet valve on the outlet side.
- the media reservoir has a main body which delimits the first media chamber at least in sections. Furthermore, the media storage device has an inner body that can be displaced in relation to the main body the second media chamber is delimited at least in sections and is arranged at least in sections within the main body.
- the inner body is displaceable relative to the main body between an insulating position and a connecting position. In the isolation position, a connecting channel between the media chambers is closed.
- the inner body has a closure section, in particular on the end of the inner body arranged in the main body, which is arranged in the insulating position in a passage of the connecting channel and is pulled out of this passage by the displacement of the inner body.
- the inner body is displaced relative to the main body by means of a media storage thread.
- Both the main body and the inner body are provided with threads for this purpose, a thread being understood in the context of this invention to mean a structure by means of which a relative rotational movement has an immediate axial relative movement.
- the process of connecting the media chambers is very easy for the user thanks to the media storage thread. To do this, he only has to cause the inner body to rotate relative to the main body of the media reservoir.
- the main body is connected in one piece or in a rotationally fixed manner to a housing of the liquid reservoir, so that a relative rotation of the inner body with respect to the housing produces the connection position.
- the liquid dispenser preferably has a removable cap which protects the discharge opening when it is in place.
- this cap is designed as a screw cap and is attached to the housing of the liquid dispenser by means of a cap thread, it is of particular advantage if the cap thread and the media storage thread are designed as opposing threads.
- the user can grasp the main body, the housing or the screw cap on the one hand and the inner body on the other hand and twist them against one another without this being associated with the risk that instead of establishing the connection state, only the screw cap is unscrewed and may even go unnoticed that the connection state has been established.
- the inner body delimits the second media chamber at least in sections. It preferably forms a wall surrounding the second media chamber. In particular, at one end of the second media chamber, this wall is perforated, so that liquid can flow after axial displacement of the inner body relative to the main body can thereby flow in the direction of the first media chamber.
- the inner body is preferably provided with an open end which can be closed by means of a closure part.
- the medium can therefore be filled into the second medium chamber through this open end, while the inner body is already in its insulating position relative to the main body. After filling, this open end is closed by means of the closure part, with the closure part and the inner body being particularly preferably designed for this purpose to produce a sealing snap connection.
- the structure of the media reservoir preferably provides that the main body has a sleeve-shaped wall, within which the second media chamber delimited by the inner body is arranged.
- An outside of the inner body and an inside of the main body are preferably matched to one another to form a sealing point, so that no liquid can escape into the environment here.
- the media storage threads may be arranged to be formed by internal threads on the main body and external threads on the inner body.
- the inner body has a sleeve section which is arranged outside of the sleeve-shaped wall of the main body and on the inside of which the inner thread of the media storage thread is provided.
- the inner body accordingly has two sleeve sections, an inner sleeve section which directly delimits the second media chamber, and an outer sleeve section on which an internal thread is provided.
- the two sleeve sections are preferably formed in one piece and in particular are connected to one another at a distal end of the inner body.
- the outside of the outer sleeve section preferably forms a gripping surface on which the user can grip the inner body for the purpose of twisting.
- This gripping surface is preferably provided with a non-round shape and/or surface structure, so that a user does not slip here during the rotary movement.
- a stop is preferably provided which prevents the partial threads of the media storage thread from being completely separated from one another.
- the media storage thread is assigned a latching device which allows the inner body and the main body to be latched in a rotationally secured manner in the isolating position and/or in the connecting position.
- This latching device preferably ensures in particular that the media chambers do not unintentionally return to the isolating position after the connection position has been established. Otherwise there would be a risk that part of the mixed liquid could not be discharged because it is in the isolated second media chamber.
- the latching device can be designed in such a way that it basically allows a return to the insulating position, but this is made more difficult by a torque that is increased in phases during the course of this.
- the latching device can also have a return lock, which mechanically completely prevents a non-destructive return.
- Preventing the recirculation is also useful because it makes it easy for the user to see whether the mixing process has already taken place at a liquid dispenser. When the inner body is in its connecting position, the blending has already taken place.
- the media reservoir has an originality section which is formed on the inner body or the main body before the dispenser is put into operation, ie is in particular a one-piece part of the inner body or main body.
- This original section is then separated from the inner body or from the main body when the media store is first transferred into the connection position. Due to the lack of the originality section or its visible separation from the inner body or main body, it is immediately clear to the user that the connection position was given at least temporarily.
- the main body of the media reservoir can be firmly connected to the one-piece or multi-piece housing of the liquid dispenser, on which the discharge opening is also provided.
- the main body is designed as a separate component which is provided for coupling to a housing component, with a corresponding coupling device preferably being designed to achieve a non-rotatable connection and being designed in particular in the form of a snap coupling.
- This configuration of the main body as a separate component allows the main body to be connected to the inner body while it is still separate from the housing of the liquid dispenser, the thereby formed and insulated second media chamber to be filled with medium and only then to connect the sub-unit formed in this way to the housing of the liquid dispenser.
- the first media chamber is preferably formed by walls of the housing of the liquid dispenser and the main body together.
- the wall of the housing itself is already capable of receiving the medium if it is properly aligned, in particular if it is aligned with the discharge opening pointing downwards, so that the sub-unit made up of the main body and inner body can then be attached to the housing and here isolated from the environment by the first media chamber.
- both media are present as liquids.
- a liquid is stored in only one of the media chambers, while the other media chamber contains a powder or granulate that can be dissolved by the liquid. If the media reservoir is transferred to the connection state, the liquid dissolves the powder or granules, in particular supported by a shaking movement and preferably also supported by the subsequent conveyance by means of a pump device in the resulting pressurization of the already mixed liquid.
- the use of the dispenser with a liquid medium on the one hand and a powder or granules on the other is primarily dependent on the intended use. However, filling one of the media chambers with a powder can generally be advantageous, since this can prevent liquid from being discharged without prior mixing.
- the liquid is arranged in the first media chamber and the powder or granules in the second media chamber, there would be a risk that the user would only discharge the liquid and not notice the error of missing mixing at first. Even if he notices the error later, he can hardly correct it, since establishing the connection position would result in a mixed liquid whose composition would not correspond to the intended composition due to the liquid that has already been partially discharged from the first media chamber.
- the media reservoir of the liquid dispenser or drop dispenser is designed to be increased in terms of its total volume by connecting the first media chamber to the second media chamber, preferably by at least 1%, preferably by at least 3%. This can be achieved if, in the course of connecting the media chambers, not only is the separation arranged between them opened, but at the same time the outer walls delimiting the media chambers to the outside are further spaced apart from each other.
- a design in which the inner body can be partially moved out of the main body by means of the media storage thread is particularly advantageous. This increases the total length of the media store. At the same time, this also leads to an increase in the overall volume.
- the increase in volume can be an advantage in particular for better mixing of the media. For example, shaking to mix the media is more effective the more free space is available in the connected media storage.
- the droplet dispenser or other liquid dispenser is preferably a side-actuation dispenser.
- the dispenser has an elongate housing extending in the direction of a main axis of extension, with an actuating button for actuating the pump device being designed as a laterally arranged actuating button which can be pressed in radially for the purpose of actuating the pump device.
- a first method it is provided that the main body and the inner body are coupled while the main body is not yet coupled to a housing of the liquid dispenser.
- the main body and the inner body thus form a structural unit which is separate from the housing of the dispenser and which then already allows the second media chamber to be filled.
- the second media chamber is already insulated by putting on the closure part.
- This structural unit comprising the main body and the inner body, is then coupled to the housing of the liquid dispenser, with the first media chamber on the side of the housing preferably having been filled beforehand.
- An alternative method provides for the main body and the inner body to be coupled while the main body is already arranged in a stationary manner with respect to a housing of the liquid dispenser, in particular has been coupled thereto or is formed in one piece therewith.
- the first media chamber can be filled beforehand before the main body is attached to the housing.
- the main body can also be coupled when the first media chamber is already filled, in order to avoid contamination from the medium as far as possible.
- this also forms the second media chamber and isolates it from the first media chamber, so that the second media chamber can now be filled.
- the media chambers can be filled with a solid or a liquid, with at least one of the media chambers containing a liquid.
- a particularly preferred variant of the method for introducing a solid provides that a liquid is first filled into the relevant media chamber. The moisture is then removed from this liquid in the still open media chamber, in particular in an oven at a temperature between 60°C and 110°C. A solid remains in the media chamber, particularly in the form of a fine porous structure. This is very readily soluble in liquid, so that mixing can take place very quickly when the liquid dispenser is put into operation.

If the screw cap 70 or the housing 12 on the one hand and the inner body 40 on the other hand are rotated in opposite directions, as illustrated by the arrows 2A, 4B, the sealing point opens and the media chambers 22, 24 are connected to one another. During this process, there is no risk of the screw cap 70 being accidentally unscrewed instead, since the threads of the screw cap 70 and the media storage thread 32, 42 run in opposite directions to one another. Turning the screw cap 70 in the direction of arrow 4B thus corresponds to an unscrewing movement of the cap, not an unscrewing movement.
- one of the latching arms of the latching device 46 latches with the latching web of the latching device 36 by being irreversibly pulled over this latching web under elastic deformation. This prevents the inner body 40 from rotating back relative to the main body 30 .
- the second locking arm serves to prevent the inner body 40 from being completely unscrewed.
- the annular tamper-evident section 47 is separated from the rest of the inner body 40 by the screwing movement of the inner body 40 in relation to the main body 30, so that in addition to the irreversible axial relative position of the inner body 40 in relation to the main body 30, the severed tamper-evident section 47 can also be seen that the connection of the media chambers 22, 24 has already taken place.
- the liquid medium from the media chamber 24 has already flowed into the first media chamber 22 in the state of FIG. 4B and has mixed there with the powder. It is usually imperative that the dispenser be shaken as a whole to achieve better blending. If necessary, the user is also requested to wait a short period of time until the media have sufficiently merged.
- the dispenser is then ready for operation as soon as the screw cap 70 has been unscrewed by a screwing movement in the opposite direction, as illustrated by the arrows 2B and 4A.
- an annular originality section 72 remains on the housing 12.
- the dispenser can now be actuated by depressing the actuating button 58 so that liquid is conveyed to the discharge opening 60 and forms a drop on the drop formation surface 62 here.
- the pumping device 50 has its inlet 53 and its outlet on the same side, so that the mixed liquid is deflected several times during pumping. This favors the homogeneity of the mixed liquid.
- the pumping device 50 is not able, or only to a limited extent, to suck in the powder in the isolated media chamber 22 that is not mixed with liquid.
- 5A to 5D, 6A to 6D and 7A to 7D show three different methods for filling the dispenser during manufacture.
- the second media chamber 24 is first filled and then preferably closed with the closure part 48 .
- the structural unit consisting of the main body 30, inner body 40 and preferably the closure part 48 is then connected to the housing 12 by inserting the main body into it and there is locked, preferably non-rotatably.
- the assembly of the main body 30, the inner body 40 and the closure part 48 can be filled at a separate location.
- An already insulated second media chamber 24 is supplied to the assembly with the housing 12 .
- first the first media chamber 22 is filled, in which case the main body 30 can already be coupled to the housing 12, but does not have to be.
- the main body can also be formed in one piece with the housing 12 .
- the inner body 40 is placed on the main body 30 already attached, so that the first media chamber 22 is isolated from the surrounding area and the second media chamber 24 .
- the second media chamber 24 is then filled and closed by means of the closure part 48 .
- FIGS. 7A to 7D similar to the method of FIGS. 5A to 5D, starting from a
- Inner body 40 which is already inserted into the main body 30 in a sealing manner, first fills the second media chamber 24.
- the filling takes place with a liquid in the manner shown in FIG. 7A.
- the liquid is dehumidified, in particular by heating the partial unit consisting of the main body 30 and the inner body 40 in an oven at over 60° for a few hours.
- the porous solid structure shown in FIG. 7B remains. Only after the moisture has been removed is the closure part 48 put on and the media chamber 24 isolated in this way.
- a liquid is filled into the first media chamber 22 . Subsequently thrown the partial unit of main body 30 and inner body 40 is inserted into the housing.
- a media reservoir 20 with two media chambers 22 and 24 that can be coupled by a thread is provided in the method of FIGS. 7A to 7D, according to a special design according to the invention it can also be provided that the filling with liquid that evaporates before sealing is also provided for liquid dispensers with a pump device is, in particular in the case of drop dispensers whose media chambers 22 and 24 can be coupled to one another in some other way, for example by removing a closure part from a connecting channel between the media chambers.
