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 drop 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.
  • a drop dispenser for dispensing cosmetic or pharmaceutical liquids in the form of individual drops 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 when there is a slight overpressure in the mixed liquid compared to the environment, in particular at an overpressure of no more than 2 bar, preferably at an overpressure of no 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 drop dispenser has a drop formation contour downstream of the discharge opening, so that the mixed liquid can collect there and then be released from the drop formation contour in the form of a drop.
  • the droplet formation contour can have a droplet formation surface surrounding the discharge opening, which in particular is preferably delimited on the outside by a tear-off edge.
  • the droplet 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 when there is negative pressure in the pump chamber, and on the outlet side, there is an outlet valve that opens when there is excess pressure in the pump chamber.
  • the pump device is designed to convey the previously mixed liquid. After the first and the second media chamber 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 pressurizing 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 pumping device is preferably designed to convey only a comparatively small amount of liquid when the pump is actuated, preferably less than 100 ⁇ l, in particular less than 50 ⁇ l. 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 drop dispenser of the type described above.
  • the liquid dispenser according to the second aspect of the invention has a media reservoir for storing media before dispensing.
  • the media reservoir has a first media chamber and a second media chamber in the manner 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 each other in a delivery condition 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 contained in the liquid containing the solid 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 is also provided in a liquid dispenser according to this second aspect of the invention for conveying the liquid from the media reservoir to the discharge opening.
  • the media reservoir has a main body which delimits the first media chamber at least in sections. Furthermore, the media store has an inner body that can be displaced relative 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 isolating 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 a passage of the connecting channel in the insulating position 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 sense of this invention as a structure by means of which a relative rotational movement has an immediate relative axial movement.
  • the media storage thread makes the process of connecting the media chambers very easy for the user. 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 in opposite directions without this being associated with the risk that instead of establishing the connection state, only the screw cap is unscrewed and possibly it even goes unnoticed that the connection status 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 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 structuring, 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 insulating position and/or in the connecting position.
  • This latching device preferably ensures in particular that the media chambers do not unintentionally return to the insulating position after the connection position has been established. Otherwise there would be a risk that part of the mixed liquid cannot be discharged because it is located in the isolated second medium 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 non-destructive return.
  • Preventing the return is also useful because it makes it easy for the user to see whether the mixing process has already taken place in a liquid dispenser. If the inner body is in its connecting position, the mixing has already taken place.
  • the media reservoir has an originality section which is formed on the inner body or on 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 tamper-evident section is then separated from the inner body or from the main body when the media reservoir is first transferred into the connection position. Due to the absence 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 design of the main body as a separate component makes it possible to connect the main body to the inner body while still separate from the housing of the liquid dispenser, to fill the second media chamber formed and isolated 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 jointly by walls of the housing of the liquid dispenser and the main body.
  • the wall of the housing is preferably already capable of receiving the medium on its own if it is aligned appropriately, 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 thereby the first media chamber isolated from the environment.
  • 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 switched to the connected 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 powder or the granules are stored in the first media chamber, which has a discharge channel that leads to the discharge opening, in particular to a pump device upstream of the discharge opening.
  • the liquid is stored in the second media chamber.
  • 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 extension axis, 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.
  • Various methods are proposed for assembling and filling a liquid dispenser according to the invention.
  • 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 is.
  • 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.
