[0003] FIELD OF INVENTION

[0004] The present invention relates to the field of bottles from which one can drink directly, i.e. of volume between 0.2 litres and 2 litres, and containing a non-alcoholic beverage.

[0005] TECHNOLOGICAL BACKGROUND OF THE INVENTION: In the field of non-alcoholic beverages, the main products are water, fruit juices, and sodas. The challenge is to reconcile two different, not to say often opposing, things: the user's taste and their health.

[0006] Many users like sodas, but these are too sweet, especially since the combination of gas plus sugar seems even more harmful than sugar alone, risking an increase in the proportion of obese people in the population.

[0007] Water is great for your health, but many users find it too bland, whether it's still or sparkling water.

[0008] Fruit juices might initially seem to strike a balance between sodas and water, offering a good compromise between taste and consumer health. However, this compromise is far from perfect, because either the amount of fruit juice is high, resulting in a drink that tastes good but is too sweet, or the amount of fruit juice is low, making the drink less harmful to health but more bland.

[0009] However, the users' strong taste for fruits and fruit drinks actually comes essentially from the users' sense of smell detecting and savoring the aroma of the fruit, much more than from the detection by the tongue which is much more limited than the sense of smell, whether by direct breathing or by retro-nasalization.

[0010] Thus, instead of giving the user fruit juice, if they are simply given water to drink while simultaneously smelling the fruit, a much better compromise can be achieved: their taste is almost as well satisfied, since the essential element of fruit detection, derived from smell, is successfully completed, while their health is entirely preserved because no sugar is ingested; only the fruit aroma is perceived. However, creating such a fruit-scented capsule that is simultaneously effective, healthy, and economically viable is not so simple, as demonstrated by the drawbacks of various prior art systems, especially when considering ease of use for the user and the stability of the capsule's positioning during use.

[0011] According to prior art, for example described in US patent 5635229 (figure 5), a water bottle is known to have an aroma diffuser located at the bottle cap, but, on the one hand, the lifespan of the aroma diffuser is short, and on the other hand, it requires a specific cap structure dedicated to a specific shape of aroma diffuser.

[0012] According to a second, earlier art, a dedicated water bottle with a specially designed spout is known, onto which a correspondingly shaped capsule is fitted, diffusing a fruit scent: several models are currently commercially available. However, the dedicated nature of the bottle presents two drawbacks: firstly, it represents a significant investment, possibly requiring multiple purchases, to access a wide range of fruity flavors, while remaining dependent on one or more specific manufacturers for the capsules, which can be quite expensive; and secondly, the user must refill the bottle with water each time, possibly from a mineral water bottle, which is a tedious task, especially since it will be necessary to do so frequently.

[0013] OBJECTS OF THE INVENTION

[0014] The invention proposes an alternative approach to solving this problem. The invention provides an aroma diffuser whose design, shape, and structure make it: either directly usable with a commercially available mineral water bottle, without any modification to the bottle's shape or structure, the aroma being diffused when the user drinks the water from the bottle; or usable with a commercially available mineral water bottle where only the closure element, i.e., the cap, is modified, without any (or very minimal) modification to the bottle body, the aroma being diffused when the user drinks the water from the bottle. Thus, the aroma diffuser offers users simplicity and flexibility in its use, also allowing them to save money.

[0015] Indeed, the ease of use is pushed to the extreme insofar as: it is the same simple gesture which will both open the neck of the bottle at the same time as opening the diffusion orifices of the aroma reservoir, and it is also the same gesture, reverse of the previous gesture, which will both close the neck of the bottle at the same time as closing the diffusion orifices of the aroma reservoir.

[0016] The invention provides both an aroma diffuser for use with a water bottle and a drinking device integrating this aroma diffuser and the water bottle with which it is used.

[0017] To this end, the invention proposes an aroma diffuser for a disposable water bottle, in particular a disposable plastic water bottle with a capacity of between 0.2 and 2 liters, comprising a neck surrounded by a thread for a screw cap and by a collar located below the thread of the neck, comprising: an aroma reservoir, of annular or partially annular shape so as to be able to be placed around the neck of this bottle, and comprising several aroma diffusion orifices distributed around the neck of this bottle; one or more fixings of the diffuser to this bottle, arranged so as to place the reservoir around the neck of this bottle; the structure of the reservoir, the arrangement of the orifices, and the arrangement of the fixings cooperating together with the cap such that: when this cap is unscrewed from the neck of this bottle,

[0018] ■ The openings are designed to allow the aroma to diffuse out of the reservoir, around the neck of this bottle, towards the top of this bottle, o when this cap is screwed around the neck of this bottle,

[0019] ■ the orifices are closed so as to prevent the diffusion of aroma outside the reservoir, o screwing the cap around the neck of this bottle mechanically causes the simultaneous closure of the orifices of the reservoir, o unscrewing the cap around the neck of this bottle mechanically causes the simultaneous opening of the orifices of the reservoir.

[0020] To this end, the invention also proposes a drinking device, comprising: a disposable water bottle, in particular a disposable plastic water bottle, with a capacity of between 0.2 and 2 liters, comprising: o a neck,

[0021] ■ surrounded by a thread for a screw cap,

[0022] ■ and by a collar, located under the neck thread, an aroma diffuser comprising: o an aroma reservoir,

[0023] ■ of annular or partially annular shape so that it can be placed around the neck of this bottle,

[0024] ■ and comprising several aroma diffusion orifices, distributed around the neck of this bottle, o one or more fixings of the diffuser to this bottle, arranged so as to place the reservoir around the neck of this bottle, o the structure of the reservoir, the arrangement of the orifices, and the arrangement of the fixings cooperating together with this cap so that:

[0025] ■ when this cap is unscrewed from the neck of this bottle,

[0026] • The openings are designed to allow the aroma to diffuse out of the reservoir, around the neck of the bottle, and upwards.

[0027] ■ when this stopper is screwed around the neck of this bottle,

[0028] • The openings are closed to prevent aroma from escaping the reservoir.

[0029] ■ Screwing the cap around the neck of this bottle mechanically causes the simultaneous closure of the reservoir openings,

[0030] ■ Unscrewing the cap around the neck of this bottle mechanically causes the simultaneous opening of the reservoir orifices.

[0031] To this end, the invention also proposes a disposable water bottle, in particular a disposable plastic water bottle with a capacity of between 0.2 and 2 liters, comprising: a neck, surrounded by a thread for a screw cap, and by a collar located below the thread of the neck; a cap comprising: a hollow, threaded cylindrical portion, being:

[0032] ■ on one side, closed by a flat part,

[0033] ■ on the other side, extended by a shutter for aroma diffusion orifices.

[0034] The present invention thus makes it possible to overcome the drawbacks of known devices by providing a diffuser:

[0035] - providing the consumer with a perceived flavour without the drawback of calories or the addition of any type of additives to the drinked contents, thus allowing for the best nutritional value according to the Nutri-Score™ scale,

[0036] - very simple to use on a standard water bottle, i.e. can be opened / closed with little effort and few manipulations, obeying a sustainable and responsible development objective: that of achieving a simple manufacturing process for the invented diffuser, requiring no change or almost no change to the manufacturing process of the containers with which it will cooperate, in particular for water bottles, which will allow a standardization of the use of such a diffuser, i.e. an easier adoption by consumers, the industries concerned, and even regulators seeing in it a dual public health issue and the avoidance of the multiplication of capsules with proprietary designs, and will thus confirm the desired objective of sustainable and responsible development.

[0037] According to preferred embodiments, the invention comprises one or more of the following features which can be used separately or in partial combination with each other or in total combination with each other, with any of the aforementioned objects of the invention.

[0038] Preferably, the aroma reservoir is deformable along a direction of deformation parallel to the axis of the annular or partially annular shape, so that: it can be compressed along this direction of deformation when the cap presses on the reservoir, and it can be relaxed along this direction of deformation when the cap ceases to press on the reservoir. The structure of the reservoir, the arrangement of the orifices, and the arrangement of the fasteners cooperating together with the cap are such that screwing the cap around the neck of this bottle mechanically causes the simultaneous closure of the orifices of the reservoir, and unscrewing the cap around the neck of this bottle mechanically causes the simultaneous opening of the orifices of the reservoir.

[0039] Thus, this deformation along the vertical axis of the bottle allows for the simultaneous opening of the neck of the bottle and the aroma diffusion orifices, as well as the simultaneous closing of the neck of the bottle and the aroma diffusion orifices, in a structurally particularly simple manner.

[0040] Preferably, the aroma reservoir is deformable like an accordion, with the orifices arranged in one or more folds of the accordion.

[0041] Thus, this deformation along the vertical axis of the bottle allows for the simultaneous opening of the neck of the bottle and the aroma diffusion orifices, as well as the simultaneous closing of the neck of the bottle and the aroma diffusion orifices, in a structurally particularly simple manner.

[0042] Preferably, the reservoir and / or diffuser is ring-shaped, making a complete turn. Once placed around the neck of the bottle, the ring-shaped reservoir and / or diffuser makes a complete turn around the neck of the bottle.

[0043] Thus, the reservoir and diffuser are positioned more stably around the neck of the bottle.

[0044] Preferably, the reservoir and / or diffuser is partially annular in shape, making between 60% and 90% of a full turn.

[0045] Thus, a good compromise is achieved between, on the one hand, the stability of the positioning of the reservoir and the diffuser around the neck of the bottle, and on the other hand, a clearance space of sufficient size is provided to receive the cap once unscrewed and removed from the neck of the bottle, even when this cap remains attached to a safety ring located around the neck of the bottle by a relatively short link.

[0046] This tamper-evident ring refers to the European directive on single-use plastics, known as the "captive cap" directive, which mandates that all plastic bottle caps must be securely attached to the bottle body from July 3, 2024. The aim of this regulation is to minimize the harmful environmental impact of plastic. In this context, standardization of captive caps is expected, ensuring that the cap is collected and recycled with the bottle. Currently, among the various captive cap solutions on the market are caps attached to a base clipped under the threads (such as the Rozanna™ brand) and hinged "snap" caps (such as the Cristalline™ brand), which do not unscrew but open from the bottom up.

[0047] Preferably, the aroma diffusion orifices are regularly distributed around the axis of the annular or partially annular shape.

[0048] Thus, regardless of the position of the fingers of the hand of the user holding the bottle when the user drinks the contents of the bottle, the diffusion of aroma around the neck of the bottle, towards the nose of the user who drinks the contents of the bottle, remains significant.

[0049] Preferably, there should be at least 4, or at least 6, or at least 10 aroma diffusion openings.

[0050] Thus, regardless of the position of the fingers of the hand of the user holding the bottle when the user drinks the contents of the bottle, the diffusion of aroma around the neck of the bottle, towards the nose of the user who drinks the contents of the bottle, remains significant.

[0051] Preferably, the fixing(s) are one or more clips which are arranged so as: to be able to clip under the collar of the neck of this bottle, so as to place the reservoir: around the neck of this bottle.

[0052] Thus, the diffuser is positioned around the neck of the bottle in an even more stable manner.

[0053] Preferably, part of the clips or each clip is formed by a narrowing of material located between its distal and proximal parts.

[0054] Thus, the mechanical production of the diffuser clip(s) is made even simpler.

[0055] Preferably, part of the clips or each clip is formed by an internal protrusion: oriented towards the inside of the annular shape of the tank, from a part of a wall of the tank or a part of the support wall of the tank, and made of a material more elastic than the material of the wall of the tank or the support wall of the tank.

[0056] Thus, the diffuser is positioned even more stably around the bottle neck. Positioning the diffuser in its clip / lock position is facilitated by a snap-fit ​​mechanism. Indeed, the internal protrusion, due to its elastic deformability, allows the diffuser to engage under the bottle's neck during its movement towards locking. And when the diffuser is pulled from its locked position to its unlocked position, it resists removal up to a certain force.

[0057] Preferably, the aroma reservoir is a replaceable consumable that is detachable from the rest of the aroma diffuser.

[0058] Thus, once emptied, the aroma reservoir can be replaced without having to replace the rest of the diffuser, which is more economical for the user and more environmentally friendly for society. The consumer only needs to replace the reservoir, which can be sold separately as a replaceable consumable after repeated use has depleted its aroma. This aroma reservoir can be marketed with packaging that covers at least the openings. The rest of the diffuser is then only intended to be replaced after a certain amount of wear. In this way, responsible durability of the diffuser and its various components is ensured. Of course, the reservoir bodies, or more generally, the diffusers according to the invention, can be marked and / or colored to indicate their contents.

[0059] Preferably, the fixings are evenly distributed around the axis of the annular or partially annular shape.

[0060] Thus, the diffuser is positioned around the neck of the bottle in an even more stable manner.

[0061] Preferably, there should be at least 2, or at least 3, or at least 4, or at least 6 fixings.

[0062] Thus, the diffuser is positioned around the neck of the bottle in an even more stable manner.

[0063] Preferably, the fixing(s) are arranged so as: to be able to clip under the collar of the neck of this bottle, so as to place the reservoir: around the neck of this bottle, below the level of the bottom of the thread surrounding the neck of this bottle.

[0064] Thus, even with a permanent safety ring around the bottle neck, to which the cap remains attached even after being unscrewed, the cap can be removed from the neck without being obstructed by the reservoir, regardless of whether the connection between the safety ring and the cap is short, medium, or long. Preferably, the aroma reservoir is a replaceable consumable that is detachable from the rest of the aroma diffuser.

[0065] Thus, the aroma reservoir, once emptied, can be replaced without having to replace the rest of the diffuser, which is more economical and more ecological for the user.

[0066] Preferably, the aroma is a fruity fragrance.

[0067] Thus, the sensation of drinking water becomes even more pleasant for the user.

[0068] Preferably, the flavoring includes a component that has an effect: either appetite suppressant, taste desensitization, or taste re-education.

[0069] Thus, the simple act of drinking water can improve or even restore other sensations useful to the user.

[0070] Preferably, the aroma includes at least one component and / or at least one essential oil, of one or more of the following fragrances: peppermint, lemon, grapefruit, cinnamon, rosemary, clove, green mandarin, thyme.

[0071] Thus, the simple act of drinking water allows the user to experience other beneficial effects, beyond that of pleasure, at the cost of a very limited inhalation of essential oil vapor, instead of having to drink a few drops of that essential oil.

[0072] Preferably, at least the reservoir, and preferably also the diffuser, is or are made of natural cellulose.

[0073] Thus, the reservoir and / or diffuser are cheaper and more environmentally friendly, because they are more easily recyclable.

[0074] Preferably, the stopper comprises: a hollow, threaded cylindrical part, being: on one side closed by a flat part, on the other side extended by a stopper, the structure of the reservoir, the arrangement of the orifices, and the arrangement of the fasteners cooperating together with this stopper so that: screwing the stopper around the neck of this bottle mechanically causes the closure of the reservoir orifices by a first movement of the stopper's stopper, unscrewing the stopper around the neck of this bottle mechanically causes the opening of the reservoir orifices by a second movement of the stopper's stopper, the second movement performing the opposite movement of the first movement.

[0075] Thus, this deformation along the vertical axis of the bottle allows for the simultaneous opening of the neck of the bottle and the aroma diffusion orifices, as well as the simultaneous closing of the neck of the bottle and the aroma diffusion orifices, in a particularly simple structural manner, by simply modifying only the lower annular part of the stopper.

[0076] Preferably, the stopper's closure is: a collar forming a protrusion around the cylindrical part of the stopper.

[0077] Thus, this deformation along the vertical axis of the bottle allows for the simultaneous opening of the neck of the bottle and the aroma diffusion orifices, as well as the simultaneous closing of the neck of the bottle and the aroma diffusion orifices, in a particularly simple structural manner, by modifying only and simply the lower annular part of the stopper, in a very simple structural manner.

[0078] Preferably, the collar includes protrusions: which are arranged so as to plug the orifices, which are made of a material which is more elastic than the rest of the collar and than the wall of the tank located around the orifices.

[0079] Thus, the sealing of the aroma diffusion orifices is achieved in a structurally very simple way.

[0080] Preferably, the stopper's closure is: a collar forming a protrusion around the cylindrical part of the stopper.

[0081] Thus, this deformation along the vertical axis of the bottle allows for the simultaneous opening of the neck of the bottle and the aroma diffusion orifices, as well as the simultaneous closing of the neck of the bottle and the aroma diffusion orifices, in a particularly simple structural manner, by modifying only and simply the lower annular part of the stopper, in a very simple structural manner.

[0082] Preferably, the collar includes protrusions arranged to seal the openings, made of a material that is more elastic than the rest of the collar. This allows the aroma diffusion openings to be sealed in a structurally very simple way.

[0083] Preferably, the reservoir has at least two compartments that can release their respective aromas sequentially, alternately, or jointly.

[0084] Thus, the release of the respective aromas from the two compartments is: either sequential, the aroma being the same in both compartments, which allows the aroma to last longer and to retain its freshness and organoleptic qualities for longer, or alternative, the aromas being different between the two compartments, which allows the user to alternate the aroma over time, for example switching from strawberry to orange, or joint, the aromas being different between the two compartments, which allows the user to mix the two aromas together in their nasal cavity, for example combining strawberry with mint.

[0085] Preferably, the diffuser contains a capsule of flavoring liquid or gel, this capsule being made of a sufficiently brittle material, and the reservoir being made of a sufficiently flexible material, so that the capsule can be broken by mechanical pressure of the hand or fingers of the user 1 on the reservoir during the first use.

[0086] Thus, the aroma is only released during the first use, thereby better preserving its freshness and organoleptic qualities before use, and in a simple and effective way.

[0087] Taste receptors can only register five distinct tastes, whereas there are hundreds of types of olfactory receptors that allow the nose to perceive many more odors. However, drinking flavored water from a bottle does not involve direct olfaction, but only retronasal olfaction. The invention also overcomes this limitation.

[0088] The disposable water bottle is preferably a disposable mineral water bottle, specifically a plastic water bottle. The plastic disposable water bottle can be replaced, for example, by a bioplastic disposable water bottle, or a bamboo disposable water bottle, or a PLA disposable water bottle.

[0089] A disposable water bottle is preferably recyclable or at least partially recyclable. A disposable water bottle is the opposite of a reusable water bottle, for example.

[0090] Advantageously, the aroma can emanate from a substance contained within it, known for its aromatic properties. The constituents or ingredients of the flavoring material or substance contained in the aroma diffuser's reservoir chamber will not be detailed hereafter. It should be understood, however, that the contents of this chamber are not necessarily limited to a particular material, form, or phase; for example, the chamber may contain ingredients in the form of solid granules, one or more gels, or one or more breakable capsules. The chamber's contents may also include another component that can not only enhance the diffusion of an aroma but also improve, in particular, its preservation and / or aeration.

[0091] BRIEF DESCRIPTION OF THE DRAWINGS

[0092] Other features and advantages of the invention will become apparent from the following description of a preferred embodiment of the invention, given by way of example and with reference to the accompanying drawings.

[0093] [Fig. 1] Figure 1 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention.

[0094] [Fig. 2] Figure 2 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention, with a first type of aroma reservoir of the aroma diffuser.

[0095] [Fig. 3] Figure 3 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention, with a second type of aroma reservoir of the aroma diffuser.

[0096] In the following description of embodiments of the invention, a container, for example a bottle, such as the one shown in the figures, is considered. In this figure, the bottle extends along a vertical axis Z, with the opening of the bottle and the diffuser according to the invention facing upwards. Thus, the "top" of the bottle is defined by its opening, on which the diffuser is to be mounted, and the bottom of the bottle is the portion opposite its opening.

[0097] Similarly, the term "internal surface" refers to the surface of a part facing inward toward the bottle, and likewise, the term "external surface" refers to the surface of a part facing outward toward the bottle, that is, in a direction substantially opposite to the direction of the bottle's interior. Likewise, the term "horizontal axis" refers to the axes X and Y perpendicular to the principal axis Z along which the bottle extends from bottom to top.

[0098] Water bottles with a slightly shorter neck (17mm instead of 21mm), a steeper thread pitch, and threads that only go around twice instead of three times around the neck of the bottle can also be used.

[0099] In one embodiment, the reservoir may contain a capsule of flavoring liquid or gel made of a brittle material, while the reservoir and its casing (cap, etc.) are made of flexible materials. In this case, the consumer must, upon first use, press on the diffuser to break the capsule.

[0100] Once the capsule is broken, it releases its contents, which will, of course, remain in the reservoir as long as the diffuser is in the closed position. In one version, such a capsule can also be placed elsewhere on the diffuser, in addition to the aroma extracts already present in the reservoir.

[0101] Guiding means, such as rails in the form of circular grooves for example, can be provided between the elements to ensure translational or rotational movements.

[0102] At the ends of this guide, one or more end stops are provided, in translation and / or rotation of the tank so as not to rotate in a vacuum.

[0103] The space around the bottle is oriented in the orthogonal directions X, Y, Z, such that the Z direction is along the vertical axis which is also the axis of symmetry of the overall cylindrical bottle.

[0104] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0105] Figure 1 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention.

[0106] In Figure 1, a cylindrical water bottle 1 terminates at its upper end, along the Z-axis, in a neck 4, also cylindrical, having an external thread 40 of the neck 4 surrounding the neck 4. Beneath this external thread 40 is an annular collar 41 of the neck 4. The annular collar 41 encircles the neck 4, either continuously or via several outwardly facing protrusions radially distributed around the neck 4. Between the external thread 40 and the annular collar 41 is an annular safety ring 30, which is connected by a tab-type safety link 31 to the cap 3. The cap 3 has an internal thread corresponding to the external thread 40 of the neck 4, allowing the cap 3 to screw onto the neck 4. The annular safety ring 30 also encircles the neck 4.The neck 4 ends at the top with an opening 43 through which the liquid contained in the bottle, for example water, can flow out of the bottle 1, towards the outside of the bottle 1.

[0107] The aroma diffuser 2 is annular and includes an aroma reservoir 5, also annular, and its support, also annular. The annular aroma diffuser 2, the annular aroma reservoir 5, and its annular support are all positioned around the neck 4 and at least partially encircle the neck 4. The reservoir 5 includes aroma diffusion orifices 6 that allow the aroma contained in the reservoir 5 to be diffused outwards from the reservoir 5 and thus outwards from the diffuser 2. The orifices 6 are preferably located on the outer side wall of the reservoir 5 (as shown in Figure 1) and / or on the upper wall of the reservoir 5. The orifices 6 of the reservoir 5 can be opened or closed by a movable shutter 7 (not shown in Figure 1).

[0108] In Figure 1, the position shown is the position of simultaneous opening of all orifices 6 allowing aroma diffusion out of reservoir 5.

[0109] Figure 1 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention, with a first type of fixing of the aroma diffuser on the beverage device.

[0110] The beverage device includes a bottle 1 and an aroma diffuser 2.

[0111] Bottle 1 is a disposable water bottle, in particular a disposable plastic water bottle, with a capacity of between 0.2 and 2 liters. Bottle 1 extends upwards with a neck 4. The neck 4 is surrounded by an external thread 41 for a screw cap 3, and by a collar 41 located below the external thread 41 of the neck 4.

[0112] The aroma diffuser 2 includes an aroma reservoir 5 that is annular or partially annular in shape so that it can be placed around the neck 4 of the bottle 1, and also includes several aroma diffusion openings 6. In one option, the reservoir 5 and / or the diffuser 2 are annular in shape, making a complete rotation around their axis. Once placed around the neck 4 of the bottle 1, the annular reservoir 5 and / or the diffuser 2 make a complete rotation around the neck 4 of the bottle 1. Thus, the reservoir 5 and the diffuser 2 are positioned more stably around the neck 4 of the bottle 1.

[0113] In another option, the reservoir 5 and / or the diffuser 2 is partially annular in shape, completing between 60% and 90% of a full rotation around their axis. This achieves a good compromise between, on the one hand, the stability of the positioning of the reservoir 5 and the diffuser 2 around the neck 4 of the bottle 1, and on the other hand, a sufficiently large clearance space, in the empty area where the missing part (the hole) of the annular shape is located, to receive the cap 3 once it has been unscrewed and removed from the neck 4 of the bottle 1, even when this cap 3 remains attached to a safety ring 30 located around the neck 4 of the bottle 1 by a relatively short link 31.

[0114] The aroma diffusion orifices 6 are regularly distributed around the vertical axis Z of the annular or partially annular shape. Thus, regardless of the position of the fingers of the user's hand holding the bottle 1 when the user drinks the contents of the bottle 1, the diffusion of aroma around the neck 4 of the bottle 1, towards the nose of the user drinking the contents of the bottle 1, remains significant, even if a minority of these diffusion orifices 6 could be temporarily blocked by one or more fingers of the user covering them at that moment.

[0115] Figure 2 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention, with a first type of aroma reservoir of the aroma diffuser.

[0116] The diffuser 2 is positioned around the neck 4 of the bottle 1, so as to block its translation along the vertical axis Z, by one or more fasteners 8. This fastener or these fasteners 8 are one or more clips 80 which are arranged to clip under the collar 41 of the neck 4 of this bottle 1, so as to place the reservoir 5 around the neck 4 of this bottle 1. The clips 80, here two in number and annular in shape, clamp the collar 41 together, thus blocking the movement of the diffuser in translation along the vertical axis Z which is also the axis of symmetry of the bottle 1 and the diffuser 2.The elasticity of the clips 80 allows for both easy installation of the diffuser 2 around the neck 4 and secure locking along the vertical axis Z, preventing the diffuser from sliding along the vertical axis Z when the bottle 1 is inverted (neck 4 oriented obliquely but slightly downwards) while the user is drinking, thus avoiding any interference. The application of limited but deliberate force by the user releases the clips 80 and frees the collar 41, allowing the diffuser to move freely up towards the top of the neck 4. This is because the collar 41 has the largest outer diameter of the neck 4, which is both larger than the outer diameter of the safety ring 30 and larger than the maximum outer diameter of the external thread 40 of the neck 4.

[0117] The aroma reservoir 5 is a deformable, accordion-shaped casing 50 with several diffusion orifices 6 located in the folds of the accordion. The aroma reservoir 5 is thus deformable like an accordion, with the orifices 6 arranged in one or more folds of the accordion. This deformation along the vertical axis Z of the bottle 1 allows for the simultaneous opening and closing of the neck 4 of the bottle 1 and the aroma diffusion orifices 6, respectively, in a structurally simple manner.

[0118] In a first embodiment, a shutter 7 is fixed on the upper part of the envelope 50. The shutter 7 extends radially over a greater radial length than the deformable envelope 50.

[0119] The obturator 7 then forms an annular collar, in the shape of an annular crown, extending radially from the outer periphery of the upper part of the accordion-shaped deformable envelope 50 of the reservoir 5. This annular collar is either continuous or formed of radial protuberances regularly distributed around the neck 4 of the bottle 1.

[0120] When the cap 3 is screwed onto the neck 4 of the bottle 1, it moves down along the Z axis (by a helical movement) towards the reservoir 5, until the open part 33 of the cap 3, the lower part in the figure, presses on the obturator 7 above the accordion-shaped envelope 50 of the reservoir 5, thus compressing the accordion, thus pressing the folds of the accordion against each other, thus closing the diffusion orifices 6 of the reservoir 5.

[0121] When the stopper 3 is unscrewed from the neck 4 of the bottle 1, it moves up along the Z axis (by a helical movement) from the reservoir 5, until the open part 33 of the stopper 3, the lower part in the figure, no longer presses on the obturator 7 above the accordion-shaped envelope 50 of the reservoir 5, thus releasing the accordion, unfolding the folds of the accordion which then spread apart, thus opening the diffusion orifices 6 of the reservoir 5.

[0122] In a second alternative embodiment, a shutter 7 is formed by a radial extension of the open part 33 of the plug 3. The shutter 7 extends radially over a greater radial length than the deformable envelope 50.

[0123] The obturator 7 then forms an annular collar extending radially from the open part 33 of the plug 3. This annular collar is either continuous or formed of radial protuberances regularly distributed around the open part 33 of the plug 3.

[0124] When the stopper 3 is screwed onto the neck 4 of the bottle 1, it moves down along the Z axis (by a helical movement) towards the reservoir 5, until the obturator 7, radially extending the open part 33 of the stopper 3, the lower part in the figure, presses on the accordion-shaped envelope 50 of the reservoir 5, thus compressing the accordion, thus pressing the folds of the accordion against each other, thus closing the diffusion orifices 6 of the reservoir 5.

[0125] When the stopper 3 is unscrewed from the neck 4 of the bottle 1, it moves up along the Z axis (by a helical movement) from the reservoir 5, until the obturator 7, radially extending the open part 33 of the stopper 3, the lower part in the figure, no longer presses on the accordion-shaped envelope 50 of the reservoir 5, thus releasing the accordion, unfolding the folds of the accordion which spread apart, thus opening the diffusion orifices 6 of the reservoir 5.

[0126] In this second embodiment, the stopper 3 comprises a hollow and threaded cylindrical part 35, being on one side closed by a flat part 34, on the other side by an open part 33 itself extended by a stopper 7, the structure of the reservoir 5, the arrangement of the orifices 6, and the arrangement of the fasteners 80 cooperating together with this stopper 3 in such a way that, screwing the stopper 3 around the neck 4 of this bottle 1 mechanically causes the closure of the orifices 6 of the reservoir 5 by a first movement of the stopper 7 of the stopper 3, and unscrewing the stopper 3 around the neck 4 of this bottle 1 mechanically causes the opening of the orifices 6 of the reservoir 5 by a second movement of the stopper 7 of the stopper 3, the second movement, a vertical upward translation along the Z axis, performing the inverse movement of the first movement which is a vertical downward translation along the Z axis.Thus, this deformation along the vertical Z axis of bottle 1 allows us to obtain, respectively, the simultaneous opening of the neck 4 of bottle 1 and the aroma diffusion orifices 6 as well as the simultaneous closing of the neck 4 of bottle 1 and the aroma diffusion orifices 6, in a particularly simple structural manner, by modifying only and simply the lower annular part 33 of the stopper 3.

[0127] In both the first and second embodiments, the structure of the reservoir 5, the arrangement of the orifices 6, and the arrangement of the fasteners 8 cooperating together with this cap 3 such that: when this cap 3 is unscrewed from the neck 4 of this bottle 1, by making an overall vertical upward displacement along the Z axis via an upward helical movement, then the diffusion orifices 6 are opened so as to allow the diffusion of aroma out of the reservoir 5, around the neck 4 of this bottle 1, towards the top of this bottle 1, the unscrewing of the cap 3 around the neck 4 of this bottle 1 mechanically causing the simultaneous opening of the orifices 6 of the reservoir 5, when this cap 3 is screwed around the neck 4 of this bottle 1, by making an overall vertical downward displacement along the Z axis via a downward helical movement,then the diffusion orifices 6 are closed so as to prevent the diffusion of aroma out of the reservoir 5, screwing the cap 3 around the neck 4 of this bottle 1 mechanically causing the simultaneous closure of the diffusion orifices 6 of the reservoir 5.

[0128] The aroma reservoir 5 is deformable along a Z-direction of deformation parallel to the Z-axis of the annular or partially annular shape, so that it can be compressed along this Z-direction of deformation when the cap 3 presses on the reservoir 5, and can be relaxed along this Z-direction of deformation when the cap 3 ceases to press on the reservoir 5. The structure of the reservoir 5, the arrangement of the orifices 6, and the arrangement of the fasteners 80 cooperate together with the cap so that screwing the cap 3 around the neck 4 of this bottle 1 mechanically causes the simultaneous closure of the orifices 6 of the reservoir 5, and unscrewing the cap 3 around the neck 4 of this bottle 1 mechanically causes the simultaneous opening of the orifices 6 of the reservoir 5.Thus, this deformation along the vertical Z-axis of bottle 1 allows for the simultaneous opening and closing of the neck 4 of bottle 1 and the aroma diffusion orifices 6, respectively, in a structurally simple manner. The clips 80 are evenly distributed around the Z-axis of the annular or partially annular shape. This ensures that the diffuser 2 is positioned even more stably around the neck 4 of bottle 1.

[0129] There are at least 2, or at least 3, or at least 4, or at least 6 clips. Thus, the diffuser 2 is positioned around the neck 4 of the bottle 1 in an even more stable manner.

[0130] In one option, part of the clips 80 or each clip 80 is formed by an internal protrusion which is oriented towards the inside of the annular shape of the reservoir 5, from the inner face 52i of the wall of the support 52 of the reservoir 5. This internal protrusion 80 is made of a material advantageously more elastic than the material of the wall 52i of the support 52 of the reservoir 5. Thus, the diffuser 2 is positioned around the neck 4 of the bottle 1 in an even more stable manner.The positioning of the diffuser 2 in its clipping / locking position is facilitated by the snapping of the clips 80 on either side (along the Z axis) of the collar 4L. Indeed, the internal protrusion 80, due to its elastic deformability properties, allows the diffuser 2 to engage under the collar 41 of the bottle 1 in its movement towards locking, and when the diffuser 2 is pulled from its locking position to its unlocking position, this diffuser 2 resists removal up to a certain removal force.

[0131] The aroma reservoir 5 can be a replaceable consumable that is detachable from the rest of the aroma diffuser, and in particular from the reservoir support 5 included in the diffuser 2. Thus, once empty, the aroma reservoir 5 can be replaced without having to replace the rest of the diffuser 2, and therefore without replacing the reservoir support 5, which is more economical for the user and more environmentally friendly. The consumer only needs to replace the reservoir 5, which can be sold separately as a replaceable consumable, after repeated use has depleted it of aroma. This aroma reservoir 5 can be marketed with packaging that covers at least the diffusion openings 6. The rest of the diffuser 2, and in particular the reservoir support 5, is then only intended to be replaced after a certain amount of wear. In this way, responsible durability of the diffuser 2 and its various components is ensured.Of course, the reservoir bodies 5, or more generally, the diffusers 2 according to the invention, can be marked and / or colored to indicate the nature of their contents. The clip(s) 80 are arranged so as to be able to clip under the collar 41 of the neck 4 of this bottle 1, and advantageously also onto the collar, so as to clamp this collar 41 between them, so as to position the reservoir 5 around the neck 4 of this bottle 1, below the level of the bottom of the external thread 40 surrounding the neck 4 of this bottle 1. Thus, even with a permanent safety ring 30, located around the neck 4 of the bottle 1, to which the cap 3 remains attached even once unscrewed from the neck 4, the cap 3 can be removed from the neck 4 without being hindered by the presence of the reservoir 5, whether the connection between the safety ring 30 and the cap 3 is short, of intermediate length, or long.

[0132] In one option, the aroma is a fruity fragrance. This makes the experience of drinking water even more pleasant for the user.

[0133] In another option, the flavoring includes a component that has a specific effect: either as an appetite suppressant, a taste desensitizer, or a taste re-educator. Thus, the simple act of drinking water can enhance or even restore other beneficial sensations for the user. Preferably, the flavoring includes at least one component and / or at least one essential oil, one or more of the following: peppermint, lemon, grapefruit, cinnamon, rosemary, clove, green mandarin, or thyme. Therefore, the simple act of drinking water can trigger other beneficial effects in the user, beyond mere pleasure, simply by inhaling a very small amount of essential oil vapor, instead of having to ingest a few drops of that essential oil.

[0134] In one option, at least reservoir 5, and preferably also diffuser 2, is or are made of natural cellulose. This makes reservoir 5 and / or diffuser 2 less expensive and more environmentally friendly, as they are more easily recyclable.

[0135] In one option, the reservoir 5 has at least two compartments that can release their respective aromas sequentially, alternately, or jointly. The movable shutter 7 then has several positions: a first position of closing the diffusion orifices 6 of all compartments, and / or a second position of opening the diffusion orifices 6 of a first compartment while simultaneously closing the diffusion orifices 6 of a second compartment, and / or a third position of opening the diffusion orifices 6 of the second compartment while simultaneously closing the diffusion orifices 6 of the first compartment, and / or a fourth position of opening the diffusion orifices 6 of all compartments.Thus, the release of the respective aromas from the two compartments is: either sequential, the aroma being the same in both compartments, which allows the aroma to last longer and to retain its freshness and organoleptic qualities for longer, or alternative, the aromas being different between the two compartments, which allows the user to alternate the aroma over time, for example switching from strawberry to orange, or joint, the aromas being different between the two compartments, which allows the user to mix the two aromas together in their nasal cavity, for example combining strawberry with mint.

[0136] In one option, the diffuser 2 contains a capsule of flavoring liquid or gel. This capsule is made of a sufficiently brittle material, and the reservoir 5 is made of a sufficiently flexible material, so that the capsule can be broken by mechanical pressure from the user's hand or fingers on the reservoir during the first use. The material of the reservoir 5 is sufficiently more flexible than the capsule material so that reasonable pressure (from an adult user's hand) on the reservoir 5 transmits enough force to break the capsule inside. Thus, the aroma is released only during the first use, better preserving its freshness and organoleptic qualities before use, and in a simple and effective way.

[0137] Figure 3 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention, with a second type of aroma reservoir of the aroma diffuser.

[0138] The aroma reservoir 5 is a spring 60, for example made of metal covered with a plastic or rubber-type material: which forms a sealed envelope when the coils of this spring 60 are joined together, the spring 60 being then compressed, thus preventing the aroma from diffusing outside the reservoir 5, but which allows the aroma to diffuse outside the reservoir 5, when the coils of this spring 60 are slightly separated from each other, the spring 60 being then relaxed.

[0139] In a first embodiment, a stopper 7 is fixed to the upper part of the envelope 50. The stopper 7 extends radially over a greater radial length than the spring 60. The stopper 7 then forms an annular collar, in the shape of an annular crown, extending radially from the outer periphery of the upper part of the spring 60 of the reservoir 5. This annular collar is either continuous or formed of radial protuberances regularly distributed around the neck 4 of the bottle 1.

[0140] When the cap 3 is screwed onto the neck 4 of the bottle 1, it descends along the Z axis (by a helical movement) towards the reservoir 5, until the open part 33 of the cap 3, the lower part in the figure, presses on the obturator 7 above the spring 60 of the reservoir 5, thus compressing this spring 60, making the coils of this spring 60 joined together, thus closing the diffusion orifices 6 of the reservoir 5.

[0141] When the stopper 3 is unscrewed from the neck 4 of the bottle 1, it moves up along the Z axis (by a helical movement) from the reservoir 5, until the open part 33 of the stopper 3, the lower part in the figure, no longer presses on the obturator 7 above the spring 60 of the reservoir 5, thus relaxing this spring 60, separating the coils of this spring 60 from each other, thus opening the diffusion orifices 6 of the reservoir 5.

[0142] In a second alternative embodiment, a shutter 7 is formed by a radial extension of the open part 33 of the plug 3. The shutter 7 extends radially over a greater radial length than the spring 60.

[0143] The obturator 7 then forms an annular collar extending radially from the open part 33 of the plug 3. This annular collar is either continuous or formed of radial protuberances regularly distributed around the open part 33 of the plug 3.

[0144] When the stopper 3 is screwed onto the neck 4 of the bottle 1, it descends along the Z axis (by a helical movement) towards the reservoir 5, until the obturator 7, radially extending the open part 33 of the stopper 3, the lower part in the figure, presses on the spring 60 of the reservoir 5, thus compressing this spring 60, making the coils of this spring 60 joined together, thus closing the diffusion orifices 6 of the reservoir 5.

[0145] When the stopper 3 is unscrewed from the neck 4 of the bottle 1, it moves upwards along the Z-axis (in a helical motion) from the reservoir 5, until the obturator 7, which radially extends the open portion 33 of the stopper 3 (the lower part in the figure), no longer presses on the spring 60 of the reservoir 5. This releases the spring 60, separating its coils and thus opening the diffusion orifices 6 of the reservoir 5. In both the first and second embodiments, the structure of the reservoir 5, the arrangement of the orifices 6, and the arrangement of the fasteners 80 cooperate with the stopper 3 such that: when the stopper 3 is unscrewed from the neck 4 of the bottle 1, moving vertically upwards along the Z-axis in an upward helical motion, the diffusion orifices 6 are opened so that to allow aroma diffusion outside of reservoir 5,around the neck 4 of this bottle 1, towards the top of this bottle 1, unscrewing the cap 3 around the neck 4 of this bottle 1 mechanically causes the simultaneous opening of the orifices 6 of the reservoir 5, when this cap 3 is screwed around the neck 4 of this bottle 1, by making an overall vertical downward displacement along the Z axis via a downward helical movement, then the diffusion orifices 6 are closed so as to prevent the diffusion of aroma out of the reservoir 5, screwing the cap 3 around the neck 4 of this bottle 1 mechanically causes the simultaneous closing of the diffusion orifices 6 of the reservoir 5.

[0146] A third embodiment, not shown in the figures, relates to a beverage device comprising an aroma diffuser according to the invention, with a third type of aroma reservoir of the aroma diffuser.

[0147] The aroma reservoir 5 is a rigid annular chamber with diffusion holes 6 located on its upper rim. The rigid annular chamber is, for example, made of rigid plastic or another material that does not deform when a screw-on cap presses against it.

[0148] The obturator 7 is formed by a radial extension of the open part 33 of the plug 3. The obturator 7 extends radially over a greater radial length than the upper ring of the undeformable annular chamber of the reservoir 5.

[0149] The obturator 7 then forms an annular collar extending radially from the open part 33 of the plug 3. This annular collar is either continuous or formed of radial protuberances regularly distributed around the open part 33 of the plug 3.

[0150] When the stopper 3 is screwed onto the neck 4 of the bottle 1, it descends along the Z axis (by a helical movement) towards the reservoir 5, until the obturator 7, radially extending the open part 33 of the stopper 3, the lower part in the figure, presses on the upper rim of the undeformable annular chamber of the reservoir 5, pressing either the flat surface of the obturator 7 or protrusions of the surface of the obturator 7 on or in the diffusion orifices 6, these protrusions being in correspondence with the diffusion orifices 6 of the upper rim of the undeformable annular chamber of the reservoir 5, thus closing the diffusion orifices 6 of the reservoir 5.

[0151] When the stopper 3 is unscrewed from the neck 4 of the bottle 1, it moves up along the Z axis (by a helical movement) from the reservoir 5, until the obturator 7, radially extending the open part 33 of the stopper 3, the lower part in the figure, no longer presses on the upper rim of the undeformable annular chamber of the reservoir 5, moving away from the diffusion orifices 6, either the flat surface of the obturator 7 or protuberances on the surface of the obturator 7, these protuberances being in correspondence with the diffusion orifices 6 of the upper rim of the undeformable annular chamber of the reservoir 5, thus opening the diffusion orifices 6 of the reservoir 5.

[0152] Thus, the structure of the reservoir 5, the arrangement of the orifices 6, and the arrangement of the fasteners 8 cooperate together with this cap 3 such that: when this cap 3 is unscrewed from the neck 4 of this bottle 1, by making an overall vertical upward displacement along the Z-axis via an upward helical movement, then the diffusion orifices 6 are opened so as to allow the diffusion of aroma out of the reservoir 5, around the neck 4 of this bottle 1, towards the top of this bottle 1, the unscrewing of the cap 3 around the neck 4 of this bottle 1 mechanically causing the simultaneous opening of the orifices 6 of the reservoir 5, when this cap 3 is screwed around the neck 4 of this bottle 1, by making an overall vertical downward displacement along the Z-axis via a downward helical movement, then the diffusion orifices 6 are closed so as to prevent the diffusion of aroma out of the reservoir 5,screwing the cap 3 around the neck 4 of this bottle 1 mechanically causes the simultaneous closure of the diffusion orifices 6 of the reservoir 5.
