Dispenser for dispensing liquid containing nicotine and / or cannabis

Description

FIELD OF APPLICATION AND STATE OF THE ART

[0001] The invention relates to liquid dispensers for dispensing a liquid, in particular a nicotine- and / or cannabis-containing liquid according to claims 1 to 14.

[0002] Such liquid dispensers replace the consumption of tobacco products. Instead of burning tobacco or other solids, the user ingests nicotine- and / or cannabis-containing liquid in atomized form. Such liquid dispensers are used regularly by their users in everyday life. It is desirable that they can be operated intuitively. TASK AND SOLUTION

[0003] The primary object of the invention is to provide structural possibilities for the realization of such a dispenser for dispensing nicotine- and / or cannabis-containing liquids, in particular a dispenser with a reliable and cost-effectively manufactured outlet valve. To achieve this object, a liquid dispenser is proposed with a liquid reservoir for storing the liquid before dispensing and a mouthpiece through which the liquid can be dispensed. A liquid channel extends between the liquid reservoir and the mouthpiece, through which liquid can reach the mouthpiece. The liquid channel is provided with an outlet valve arrangement with which the liquid channel can be closed and opened.

[0004] In particular, a liquid dispenser according to the invention can have an elongated and slender shape extending in a main direction of extension and can be handled similarly to a cigarette. The mouthpiece and the liquid reservoir, preferably provided opposite it, preferably each extend in the direction of this main direction of extension. An outer side of the liquid dispenser can have a uniform cylindrical shape. However, the liquid dispenser is preferably designed with a larger cross-section in the region of the liquid reservoir than in the region of the mouthpiece.

[0005] The user encloses the mouthpiece with their lips or grasps it between their teeth when liquid is to be dispensed. The mouthpiece preferably has an approximately tubular shape with an outlet opening at one end. The outlet opening preferably has a clear cross-section of at least 20 mm2. The liquid is fed inside the mouthpiece and is thereby atomized, preferably for the purpose of ingestion. The mouthpiece is preferably connected to the environment via a further channel so that the user can also draw in air along with the liquid. This air inlet channel is preferably provided as a radially aligned opening in a wall of the mouthpiece.

[0006] When ready for sale, the liquid reservoir is filled with the dispensing liquid, i.e., in particular, with a liquid containing nicotine and / or cannabis. The volume of the liquid reservoir is preferably less than 100 ml, particularly preferably less than 30 ml.

[0007] According to two aspects of the invention, different designs of the exhaust valve arrangement are proposed, which, however, could also be implemented together.

[0008] According to a first aspect of the invention, it is provided that the outlet valve arrangement has an elastically deformable hose section which forms at least part of the liquid channel.

[0009] In order to open and close the outlet valve arrangement, an actuating surface is provided on an outer side of the dispenser, in particular for manual actuation or actuation by mouth. This actuating surface is movable relative to a housing part surrounding the liquid channel and / or relative to the liquid reservoir and is coupled to a tube-forming segment which converts a displacement of the actuating surface induced by the user into a deformation or re-deformation of the tube section. By applying force to the actuating surface, the tube section can thus be deformed from a state in which it closes the liquid channel to a state in which it opens the liquid channel. A return spring is preferably provided by which the actuating surface is subjected to force in the direction of its unactuated end position and against whose force the actuation of the actuating surface takes place.

[0010] Two different concepts for using the hose section as part of the exhaust valve assembly are preferred. The first of the concepts is based on compressing the hose, the second of the concepts is based on kinking the hose.

[0011] In the first concept, the hose forming segment can be displaced orthogonally to the hose section. In one possible design, it can be displaced exclusively orthogonally, i.e., with a direction of displacement oriented at a 90° angle to the extension direction of the hose section. The displaceability of the hose forming segment can also have an orthogonal component, but at the same time, it can also be displaced parallel to the extension direction of the hose section.

[0012] The hose forming segment is displaced between a closing end position and an opening end position. In the closing end position, the hose forming segment presses against the hose section from the outside, thus pressing it against a counter surface, in particular against a stationary holding surface, for example, a holding surface on the inner circumference of a pipe section partially enclosing the hose section. The clear cross-section of the hose section is thereby reduced to a significant extent or even to zero.

[0013] In the opening end position, the hose forming segment is displaced away from the hose section so that the elastic hose section can relax again under the influence of the fluid pressure and allows the fluid to flow through the hose section.

[0014] The actuating surface is preferably pressed in the direction of a center or central axis for the purpose of discharge. To thereby effect a movement of the tube-forming segment away from the tube section, a reversal of the direction of movement between the actuating surface and the tube-forming segment can be provided, so that the tube-forming segment is displaced in a direction of movement that deviates from the direction of movement of the actuating surface. This can be easily achieved, for example, using a tilting element that has the tube-forming segment and the actuating surface on opposite sides of a tilting axis.

[0015] Another possible design provides for the tube forming segment and the actuating surface to be located on opposite sides of the tube section. The actuating surface and the tube forming segment are then displaced in approximately the same direction, preferably in exactly the same direction and to the same extent. In such a design, the combination of actuating surface and tube forming segment encompasses the tube section.

[0016] In the second concept, the closing of the outlet valve assembly is based on a bend in the hose. The hose forming segment can be moved between a closing end position and an opening end position, preferably by a fixed or even integral connection of the hose forming segment to the actuating surface.

[0017] In the closing end position, the hose forming segment forces the hose section into a closed state in which the hose section is kinked at least once in at least one kink area. The hose section is kinked to such an extent that opposing inner surfaces of the hose section lie tightly against one another in the kink area. The cross-section of the hose, which is round in the relaxed state, for example, changes its shape towards the kink area, becoming initially elliptical, which narrows linearly at the actual kink point and thereby reduces the cross-section to zero. This kink point forms the separation point of the outlet valve. The hose section kinks at the kink point preferably by at least 90°, in particular by at least 105°.The narrowest radius of curvature on an outer side of the hose section at the kink point is preferably less than three times the diameter of the hose section, in particular preferably less than twice the diameter of the hose section.

[0018] As soon as the tube forming segment has returned to its opening end position, the bending area returns to a more relaxed state of the tube section, in which the clear cross-section of the tube section opens again at the kink. Fluid can now flow through the tube section again. In the open state, the tube section directions on both sides of the kink preferably deviate from each other by less than 90°, particularly preferably by less than 75°.

[0019] Whether fluid can pass through a kinked hose section also depends on the fluid pressure. It can be advantageous if the hose section has several kink areas, in particular two kink areas, where the clear internal cross-section of the hose section at the kink point narrows to zero or close to zero. Such two or more kink areas, which narrow simultaneously when the actuating surface is pressed down, can together achieve the valve effect in that a first kink area can still be flowed through by fluid under high pressure, but reduces the pressure sufficiently that the kink in the second kink area can completely prevent flow.

[0020] If there is more than one kink, it is particularly advantageous if the hose section bends in opposite directions in the two kink areas, i.e., in a Z-shape. Such a Z-shape allows the adjacent hose sections outside the kink areas to have an identical direction of extension and to be connected by a connecting segment, which forms a kink area with the hose sections on both sides. However, in this case, the adjacent hose sections are offset from one another.

[0021] To prevent this, it can be advantageous if the hose section has a total of four bending areas that form the corners of a parallelogram shape. Two of these bends are bent to form a liquid-tight seal when the hose forming segment is positioned in the closing end position, i.e., they have a clear diameter of zero in the area of their respective bends. The other two bending areas do not close when the hose forming segment is pressed into its closing end position, but rather reduce their bend angle.

[0022] Depending on the type of deformation of the hose section required to open the outlet valve arrangement, the hose forming segment can be separate from the hose section and only pressed against the hose when force is applied to the actuating surface. However, the hose forming segment can also have a coupling section for permanent coupling to the hose section, for example in the form of a laterally slotted hose clamp into which the hose section is inserted. Such a coupling is useful in order to be able to move the hose section safely both when transitioning to the closed state and when transitioning to the open state, without having to utilize the inherent recovery tendency of the hose section or the recovery tendency caused by the fluid pressure.

[0023] A liquid dispenser of the type described is used by the user as needed, typically several times a day. To use it, the user places the liquid dispenser in the correct location, specifically near the mouth, and then presses the actuating surface.

[0024] In one embodiment, this pressure can be manually applied. For example, the user presses the actuating surface of a designated button or slider with their index finger. The actuating surface is displaced relative to the housing, thereby opening the exhaust valve assembly.

[0025] Preferably, the actuating surface can be radially depressed relative to the main extension direction of the liquid dispenser or a cylindrical portion thereof to open the outlet valve arrangement. This design is particularly suitable for a very simple construction with a hose-forming segment that compresses the hose section to close it, and which is spaced apart from the hose section by applying force to the actuating surface. Another preferred configuration provides that the actuating surface, which is preferably provided on a sleeve-like component for this purpose, is axially displaceable to open the outlet valve arrangement.

[0026] In addition to manual operation, oral operation is considered appropriate. Here, the user applies pressure to the mouthpiece with their lips or teeth, which also exerts force on the actuating surface.

[0027] The actuating surface is preferably located near the mouthpiece and can be depressed by the user's lips or teeth. The required force should ideally be less than 5 Newtons.

[0028] The actuating surface can be pressed down relative to the mouthpiece, in particular relative to an opposite wall of the mouthpiece. In particular, the actuating surface can be designed to be pivotable.

[0029] However, the actuating surface can also be integral with the entire mouthpiece or be formed by the entire mouthpiece. This mouthpiece can then be displaced as a whole, in particular axially displaced, relative to the liquid reservoir or other housing sections of the liquid dispenser, with respect to a main direction of extension.

[0030] A liquid dispenser of the type described is preferably provided with a pressure accumulator so that the liquid flows out automatically when the outlet valve arrangement is open.

[0031] In particular, the fluid reservoir can be partially replaceable. For this purpose, it is proposed, in particular, that the fluid reservoir have a receptacle for accommodating a replaceable fluid cartridge. A fluid cartridge is inserted into this receptacle, preferably without the use of tools. Once an inserted cartridge is empty, the user can remove it from the receptacle and replace it with a new one.

[0032] Liquid cartridges of the type described preferably have an additional valve, which separates their storage space from the environment until use. This additional valve can be opened, in particular, by inserting the liquid cartridge into the receptacle. In particular, the liquid cartridges have an outlet nozzle that, when inserted into the receptacle, is pressed in or tilted relative to a storage wall of the liquid cartridge, thereby opening the additional valve.

[0033] The liquid dispenser according to the second aspect of the invention also comprises a liquid reservoir for storing the liquid prior to dispensing, a mouthpiece through which the liquid can be dispensed, and a connecting liquid channel that can be opened and closed by means of an outlet valve arrangement. All of the aforementioned features can also be implemented individually or in combination in the liquid dispenser according to this second aspect of the invention.

[0034] In this second aspect of the invention, the outlet valve arrangement comprises a tilting valve with a tiltable outlet nozzle through which the fluid channel passes. The tilting valve is opened or closed depending on the tilting position of the outlet nozzle. Technically, a tilting valve can be implemented in particular such that a preferably circumferential valve surface is connected to the outlet nozzle, which is lifted from a likewise preferably circumferential counter-surface by the tilting movement, thus allowing fluid to flow to the mouthpiece. The outlet nozzle can preferably be tilted in any direction to be opened.

[0035] In addition to the described hose valve, a tilt valve has proven to be a particularly advantageous and cost-effective design for an outlet valve arrangement. It can be opened with just a slight tilt, yet still allows for very controlled opening and closing.

[0036] In the simplest case, such a tilt valve can be actuated directly via the mouthpiece. For this purpose, the mouthpiece is designed to be movable relative to the liquid reservoir and is coupled to the outlet nozzle in such a way that movement of the mouthpiece relative to the liquid reservoir tilts the outlet nozzle. This can be achieved, for example, by firmly connecting the mouthpiece to the outlet nozzle and allowing the user to open the tilt valve by slightly angling the mouthpiece relative to the liquid dispenser, preferably at an angle of less than 10°.

[0037] However, even with this liquid dispenser according to the second aspect of the invention, it is possible to provide an actuating surface on the outside of the dispenser, separate from the mouthpiece, which is movable relative to the liquid reservoir and / or the mouthpiece and is operatively coupled to the outlet nozzle, so that the outlet nozzle is tilted by applying force to the actuating surface. Manual actuation or actuation by mouth is also possible here, with the actuating surface being placed closer to the mouthpiece or further away from it, depending on the desired method.

[0038] In the simplest case, the actuating surface can be displaced orthogonally to the outlet nozzle and, when pressed in, push the outlet nozzle into a tilted position.

[0039] If a displacement of the outlet nozzle relative to the mouthpiece is intended when opening the tilt valve, it may be useful to provide a section of hose between the outlet nozzle and the mouthpiece to compensate for the resulting offset.

[0040] The tilt valve can, in principle, be provided separately from a replaceable fluid cartridge. However, it is preferred that the fluid reservoir have a replaceable fluid cartridge with the tilt valve directly attached. Thus, replacing the fluid cartridge also involves replacing the tilt valve.

[0041] The liquid dispenser is preferably designed to dispense the liquid in finely atomized form. This can be achieved, for example, via an atomization device with a swirl chamber at the end of the liquid channel. However, a design in which a dispensing nozzle unit is provided through which the liquid can be dispensed into the mouthpiece is preferred. This dispensing nozzle unit preferably has a plurality of nozzle openings, in particular a nozzle plate in which a plurality of nozzle openings are provided. The nozzle openings can in particular be aligned in a divergent manner. Such a nozzle plate enables the production of a particularly fine droplet jet even with an overall very low volume flow, as is desired in the preferred fields of application of the liquid dispenser. The nozzle plate preferably has at least 10 nozzle openings.The clear cross-section of the nozzle openings at the narrowest point is preferably less than 250 µm 2< .

[0042] The hose section mentioned in the first variant of the invention is preferably made of an elastic plastic material, in particular of polyethylene, polypropylene or of a material containing polyethylene and / or polypropylene. Since only small liquid flows are required in the preferred field of application of dispensing liquids containing nicotine and / or cannabis, the hose section preferably has an inner diameter of 2.0 mm or less, in particular of 1.0 mm or less. Furthermore, the hose section preferably has a wall thickness of 1.0 mm or less, particularly preferably of 0.5 mm or less. The wall thickness is preferably 0.1 mm or more, in particular 0.3 mm or more. The inner diameter is preferably between 30% and 70% of the outer diameter of the hose section.

[0043] Although the described liquid dispensers are intended in particular for the aforementioned field of application of dispensing liquids containing nicotine and / or cannabis, some aspects of the invention can also be implemented separately.

[0044] A separate aspect of the invention is a design of a liquid dispenser comprising a liquid reservoir configured as a pressure reservoir for storing the liquid prior to dispensing and a dispensing opening, wherein the dispensing opening does not necessarily have to be located in the region of a mouthpiece. The liquid reservoir and the dispensing opening are connected to one another via a liquid channel, to which an outlet valve arrangement is assigned, by means of which the liquid channel can be closed and opened. As explained above with regard to the second concept of the first variant of the invention, the outlet valve arrangement comprises an elastically deformable hose section, which forms part of the liquid channel and at least part of the outlet valve arrangement, which can preferably be switched by the user using a handle.

[0045] When the outlet valve assembly is open, fluid can flow through the hose section. When closed, the hose section is bent at least once in at least one bending region, with a plurality of bends preferably being provided in the manner described above. At the bending points, opposing inner surfaces of the hose section bear against one another in a sealing manner, preventing fluid from flowing through the hose section.

[0046] This basic principle of a hose section bent once or multiple times to form a switchable outlet valve can be applied to various liquid dispensers. This technology is particularly suitable for the nicotine or cannabis dispensers described above, but also for dispensing a liquid medication, a mouth spray, or a dental care product. The liquid reservoir, which is preferably designed as a pressure reservoir, holds the corresponding liquid in such designs.

[0047] The additional possible features of a nicotine or cannabis dispenser described above can also be used individually or in combination in such a dispenser in another application area. WO2019 / 224531 describes a nicotine dispenser with a pressure-dependent opening valve that acts on a fluid channel. BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 12 und 13 show alternative designs to the embodiment of the Fig. 11A und 11B . DETAILED DESCRIPTION OF THE EMBODIMENTS

[0049] The Fig. 1A und 1B show a preferred design of a liquid dispenser according to the invention in an uncut view. Such a liquid dispenser 10, intended in particular for dispensing liquid containing nicotine or cannabis, has a shape oriented in the direction of a main extension direction 2. A mouthpiece 30 is provided at a proximal end of the liquid dispenser 10. A liquid reservoir 20 is provided at an opposite distal end, which in the example of the Fig. 1A und 1B a shaft-shaped receptacle 22 which is closed by a closure 23 and is intended for receiving a Fig. 1A und 1B Between the fluid reservoir 20 and the mouthpiece 30 there is a Fig. 1A und 1B A connecting fluid channel 40 (not shown) is provided, which has an outlet valve arrangement 50. This outlet valve arrangement 50 allows the fluid channel 40 to be opened from a closed state in the resting state, for example by means of an actuating surface 52. If the outlet valve arrangement 50 is opened, fluid can flow through the fluid channel 40 to the mouthpiece 30 and be discharged there in the form of an atomized spray jet, as shown in Fig. 1B The liquid sprayed or nebulized in this way is sucked in by the user, with air preferably also being sucked in through air inlet channels 38.

[0050] The Fig. 2A und 2B show a first embodiment in a sectional view. Here, it can be seen that the aforementioned liquid cartridge 24, which has an outlet valve 26, is arranged in the receptacle 22 of the liquid reservoir 20. When the liquid cartridge 24 is accommodated in the liquid dispenser 10, this outlet valve 26 is open.

[0051] A tubular housing section extends from an outlet nozzle 27 of the fluid cartridge 24, within which a hose section 60 is positioned. The tubular housing section surrounding the hose section 60 is provided with an opening on its underside. Located therein is a hose forming segment 54 that can be displaced in the displacement direction 4 and is pressed upward by a return spring 28 and thus against the hose section 60.

[0052] When the dispenser is at rest, the hose section 60 is compressed to such an extent that no liquid can flow toward the mouthpiece 30 and the dispensing nozzle unit 32 located there. The aforementioned hose forming segment 54 is connected, for example, by means of a snap-in connection to an actuating component, on which the aforementioned actuating surface 52 is also provided. A one-piece design is also possible.

[0053] If now in the Fig. 2B As illustrated, if the actuating surface 52 is manually pressed down against the force of the return spring 58, part of the force acting on the hose section 60 is eliminated, so that the liquid channel 40 is opened and liquid can flow to the dispensing nozzle unit 32. Here, the liquid is pressed against a nozzle plate 34 provided with fine perforations, which causes the desired atomization of the liquid. While actuating the actuating surface 52, the user sucks on the mouthpiece 30 enclosed by their lips, whereby in addition to the liquid dispensed by the dispensing nozzle unit 32, air is also sucked in, which can flow into the mouthpiece through an air inlet channel 38.

[0054] In the embodiment of the Fig. 3A und 3B The basic functionality is very similar. Here, too, a liquid channel 40 formed in sections by a hose section 60 is provided between an outlet nozzle 27 of a liquid cartridge 24 and the dispensing nozzle unit 32. The hose section 60 is also compressed here by a hose forming segment 54, which differs from the design of the Fig. 2A und 2B from above onto the hose section 60. In this design, the hose forming segment 54, together with the actuating surface 52, is part of a common rocker element which can be pivoted about the pivot axis 6.

[0055] The opening of the outlet valve arrangement 50 takes place in the embodiment of the Fig. 3A und 3B with the mouth. The actuating surface 52 therefore extends into the area of the mouthpiece 30 and, together with the mouthpiece 30, can be enclosed by the lips or teeth of a user. If the user presses their lips or teeth together, the rocker element pivots counterclockwise relative to the figures and thus pushes the tube forming segment 54 upwards against the force of the return spring 58. This eliminates the force compressing the tube section 60 and results in the liquid being discharged, as shown in Fig. 3B is clarified.

[0056] The Fig. 4A und 4B show a significantly different design of a liquid dispenser 10. In this design, the liquid channel 40 between the liquid reservoir 20 and the mouthpiece 30 as well as the dispensing nozzle unit 32 provided there is also partially realized with a hose section 60. However, this hose section is not directly compressed by a hose forming segment 54. The hose forming segment 54, which here encompasses a partial section of the hose section 60, rather ensures a displacement of the hose section 60, by means of which two kinks 60A, 60B can be opened and closed. If the actuating surface 52 provided on a sleeve-shaped body is moved relative to the Fig. 4A und 4B to the right, the bend radius at the bends 60A and 60B decreases. The result is that liquid can flow through the liquid channel 40 to the discharge nozzle unit 32. If the actuating surface 52 is released, the return spring 58 presses the actuating surface and also the tube forming segment 54 back into its left end position, in which the bend angle and the radius of curvature in the area of the bends 60A, 60B are changed such that these bends together prevent the flow of liquid through the liquid channel 40.

[0057] The operation of a liquid dispenser must be in accordance with the Fig. 4A und 4B not at the actuating surface 52. Alternatively, it can also be provided that the mouthpiece 30, but not the discharge nozzle unit 32, is firmly connected in the axial direction to the component of the actuating surface 52, so that pressing the mouthpiece 30 in the direction of the liquid reservoir 20 causes the outlet valve arrangement 50 to open.

[0058] The design of the Fig. 5A und 5B is similar to that of Fig. 4A und 4B , since here too a hose section 60 is used, which can bend in the area of two kinks 60A, 60B in order to prevent a liquid flow from the liquid reservoir 20 to the discharge nozzle unit 32. Unlike the design of the Fig. 4A und 4B However, the corresponding deformation of the hose section 60 for the purpose of opening and closing the outlet valve arrangement formed thereby is not achieved by an axial displacement, but by a radial one. The actuating surface 52 can be pressed down for this purpose, indirectly reducing the radius of curvature and the angle of curvature in the region of the bends 60A, 60B, so that liquid can then flow through the liquid channel 40 to the discharge nozzle unit 32.

[0059] When designing according to Fig. 6A und 6B It is provided that a partial axial displacement of the hose section 60 takes place. For this purpose, a one-piece component is provided, which forms both the mouthpiece 30 and the hose forming segment 54. If the hose section is partially axially displaced by applying force to the liquid reservoir 20 relative to this component and the mouthpiece 30, a relaxation occurs at the bends 60A, 60B, through which the liquid can reach the discharge nozzle unit 32.

[0060] Both Fig. 7A und 7B is similar to the design of the Fig. 3A und 3B a rocker-like element is provided, on which both the actuating surface 52 projecting up to the mouthpiece 30 and the tube forming segment 54 are provided. If the lips or teeth are pressed together by the user, this rocker element pivots counterclockwise and against the force of the return spring 58. In this case, the tube forming segment 54 is displaced upwards and thus moves the tube section 60 into the position of Fig. 7B in which liquid can reach the discharge nozzle unit 32 from the liquid reservoir 20.

[0061] Fig. 8 shows again the design of the Fig. 4A bis 7B The intended shape of the hose section 60, which here roughly describes a parallelogram shape, is shown. In addition to the two bends 60A and 60B, there are correspondingly two further curvature areas 60C and 60D. If the hose section 60 is deformed for the purpose of opening the outlet valve arrangement, the angle of curvature is reduced at the bends 60A, 60B, while it is increased at the bends 60C and 60D in a manner that is irrelevant for the fluid flow.

[0062] An alternative design is the Fig. 9 Here, there are no paired bends 60C, 60D. Instead, the hose section 60 is slightly curved as a whole on both sides of the bends 60A, 60B in order to ensure that the two ends of the hose section are aligned with each other.

[0063] The design of the Fig. 10 has only a single kink point 60A. Furthermore, the hose is laid in a bend that does not form a kink point, forming the aforementioned kink point 60A.

[0064] All three hose designs of the Fig. 8 bis 10 could be found in the liquid dispensers of the Fig. 4A bis 7B be used.

[0065] The Fig. 11A und 11B show a different design of an outlet valve arrangement. Here, the outlet valve arrangement 70, which allows liquid to flow to the discharge nozzle unit 32, is designed in the manner of a tilt valve 74. In the exemplary embodiments presented here, this tilt valve 74 is firmly connected to a liquid cartridge 24, but could also be designed separately from the liquid cartridge 24. The tilt valve 74 has an outlet nozzle 72, which, at its right-hand end in the figures, merges into a valve plate 73. If the outlet nozzle 72 is tilted, the valve surface 73 also tilts, allowing liquid to escape into the outlet nozzle 72 and from there through a hose section 62 to the discharge nozzle unit 32.

[0066] When designing the Fig. 11A und 11B It is provided that a deflection of the outlet nozzle 72 takes place via an actuating surface 52, which is provided for manual actuation, as shown in Fig. 11B The hose section 62 ensures that the liquid flowing out through the outlet nozzle 72 is directed to the discharge nozzle unit 32.

[0067] In the variant of the Fig. 12 A tilt valve 74 of the same type is also provided. However, in this case, it is opened by an actuation that is shifted by means of the mouth, i.e., by pressing the teeth or lips together. The actuating surface 52 is part of a rocker element, the end of which opposite the actuating surface 52 causes the outlet nozzle 72 to tilt when the actuating surface 52 is pressed down.

[0068] A particularly simple design shows Fig. 13A tilt valve 74 is also provided here. However, in this case, it is firmly connected to the mouthpiece 30. The tilt valve is opened by the user slightly tilting the liquid reservoir 20 relative to the mouthpiece 30. The outflowing liquid passes through the outlet nozzle 72 to the mouthpiece 30 and the discharge nozzle unit provided there.
