Description

Title of the invention: Aroma diffuser for disposable water bottle FIELD OF INVENTION

[0001] The present invention relates to the field of bottles from which one can drink directly, that is to say of a volume between 0.2 litres and 2 litres, and containing a non-alcoholic beverage. TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0002] In the field of non-alcoholic beverages, there are mainly 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.

[0003] 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.

[0004] Water is great for health, but many users find it too bland, whether it is still or sparkling water.

[0005] Fruit juices might at first glance seem to represent a happy medium between sodas and water, striking a good balance between taste and consumer health. But here again, the compromise is far from perfect, because either the quantity of fruit juice is high, and the drink tastes good but remains too sweet, or the quantity of fruit juice is low, and the drink becomes less harmful to health but more bland in taste.

[0006] However, the users' strong taste for fruits and fruit drinks actually comes essentially from the users' sense of smell detecting and enjoying 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.

[0007] Thus, instead of making the user drink fruit juice, if we simply make him drink water, while simultaneously allowing him to smell the fruit, we can achieve a much better compromise: his taste is almost as well satisfied, since the essential part of the fruit detection, coming from olfaction, is well done, while totally preserving his health since no sugar is swallowed, the scent of the fruit is only smelled.

[0008] However, making such a fruit perfume scent capsule, which is both effective, good for health, and economically interesting, is not so simple, as shown by the disadvantages of the various systems of the prior art, especially if one also takes into account the simplification of use for the user and the stability of positioning of the capsule during use by the user.

[0009] According to prior art, for example described in US patent 5635229 (Figure 5), a water bottle associated with an aroma diffuser located at the level is known. of the bottle cap, but, on the one hand the lifespan of the aroma diffuser is short, and on the other hand requires a specific cap structure dedicated to a specific shape of aroma diffuser.

[0010] According to a second prior 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 water bottle entails two drawbacks: firstly, it represents a certain investment, possibly to be made several times, to have access to a wide range of fruity flavors, while remaining dependent on one or more specific manufacturers for purchasing the capsules, which can thus be quite expensive; and secondly, the user must refill their water bottle with water each time, possibly from a mineral water bottle, which is a tedious operation for the user, especially since they will have to do it frequently. OBJECTS OF THE INVENTION

[0011] The invention proposes an alternative approach to solving this problem. The invention provides an aroma diffuser whose arrangement, shape, and structure maximize the user's perceived taste, including both taste and smell, without harming their health. To this end, the invention provides an aroma diffuser that allows both direct olfaction (breathing) and retronasal olfaction (retronasalization) for the user, thus maximizing their sensation without impacting their health, since the user only absorbs scents and does not actually drink sweetened fruit juice.

[0012] Thus, the user will be able to smell the aroma or aromas diffused, both through the nose by breathing them in at the front of his nasal cavity, and by retro-nasalization by bringing this aroma or these aromas back through the back of his nasal cavity.

[0013] 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.

[0014] 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 and comprising a neck, including: • an aroma reservoir, • of an annular or partially annular shape so that it can be placed around the neck of this bottle, • comprising several initial aroma diffusion orifices, arranged around the neck of this bottle, oriented towards the outside of the neck of this bottle, • in such a way as to allow the aroma to diffuse out of the reservoir, around the neck of this bottle, towards the outside of the neck of this bottle, towards the top of this bottle, when the reservoir is placed around the neck of this bottle, • so that the diffused aroma can be absorbed, by inhalation through the nose, by a user drinking the water from this bottle, • and comprising a second orifice or several second aroma diffusion orifices, oriented either towards the inside of the neck of this bottle or towards the inside of the space located above the neck and in line with the neck of this bottle, • so as to allow the aroma to be diffused out of the reservoir, either into the neck of the bottle or into the space above and extending from the neck of the bottle, when the reservoir is placed around the neck of the bottle, • so that the diffused aroma can be absorbed, via retronasal inhalation, by a user drinking the water from 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.

[0015] To this end, the invention also 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 and comprising a neck, including: • an aroma reservoir, • of an annular or partially annular shape so that it can be placed around the neck of this bottle, • comprising several initial aroma diffusion orifices, arranged around this annular shape, oriented outwards from this annular shape, • in such a way as to allow the aroma to diffuse out of the reservoir, around the neck of this bottle, towards the outside of the neck of this bottle, towards the top of this bottle, when the reservoir is placed around the neck of this bottle, • so that the diffused aroma can be absorbed, by inhalation through the nose, by a user drinking the water from this bottle, and comprising a second orifice or several second aroma diffusion orifices, then oriented towards the interior of this annular shape, in order to allow the aroma to be diffused out of the reservoir, either into the neck of the bottle or into the space above and extending from the neck of the bottle, when the reservoir is placed around the neck of the bottle, so that the diffused aroma can be absorbed, via retronasal inhalation, by a user drinking the water from 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.

[0016] 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 between 0.2 and 2 litres, comprising: a collar, An aroma diffuser including: an aroma reservoir, of annular or partially annular shape so as to be able to be placed around the neck of this bottle, comprising several first diffusion orifices aromas, then arranged around the neck of this bottle, oriented towards the outside of the neck of this bottle, in order to allow the aroma to diffuse out of the reservoir, around the neck of this bottle, towards the outside of the neck of this bottle, towards the top of this bottle, when the reservoir is placed around the neck of this bottle, • so that the diffused aroma can be absorbed, by inhalation through the nose, by a user drinking the water from this bottle, and comprising a second orifice or several second aroma diffusion orifices, then oriented towards the inside of the neck of this bottle or oriented towards the inside of the space located above the neck and in line with the neck of this bottle, • so as to allow the aroma to be diffused out of the reservoir, either into the neck of the bottle or into the space above and extending from the neck of the bottle, when the reservoir is placed around the neck of the bottle, • so that the diffused aroma can be absorbed, via retronasal inhalation, by a user drinking the water from 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.

[0017] The present invention thus makes it possible to overcome the drawbacks of known devices by providing a diffuser: - providing the consumer with a perceived flavour without the drawback of calories or the addition of any type of additives to the drinked content, thus allowing the best nutritional value according to the "Nutriscore" scale ("registered trademark"), - very simple to use on a standard water bottle, i.e., it can be opened / closed with little effort and few steps, - obeying an objective of sustainable and responsible development: that of achieving a simple manufacturing process for the invented diffuser, requiring no change or almost no change in 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 who see it as a dual issue of public health and of avoiding the multiplication of capsules with proprietary designs, and will thus confirm the desired objective of sustainable and responsible development.

[0018] 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.

[0019] Preferably, the aroma reservoir includes only one second aroma diffusion orifice, then oriented towards the inside of the neck of this bottle or oriented towards the inside of the space located above the neck and in the extension of the neck of this bottle.

[0020] Preferably, the aroma reservoir includes only one second aroma diffusion orifice, then oriented towards the inside of this annular shape.

[0021] Thus, retronasalization is satisfactorily achieved with a minimum number of diffusion orifices, here only one, because on the internal side, the fingers of the user's hand, whatever their position, cannot interfere with the diffusion of aroma.

[0022] Preferably, the aroma reservoir comprises two or more concentric cylindrical walls, the second aroma diffusion orifice or orifices, then oriented towards the inside of the neck of this bottle or oriented towards the inside of the space located above the neck and in the extension of the neck of this bottle, belongs or belong to the innermost concentric cylindrical wall of the reservoir.

[0023] Preferably, the aroma reservoir comprises two or more concentric cylindrical walls, the second aroma diffusion orifice or orifices, then oriented towards the inside of this annular shape, belongs or belong to the innermost concentric cylindrical wall of the reservoir.

[0024] Thus, retronasalization is obtained satisfactorily, without risk of the liquid exiting through the neck of the bottle entering the aroma reservoir, even though the aroma exits through the internal orifice(s) to enter the flow of liquid through the neck going from the inside of the bottle to the inside of the user's mouth.

[0025] Preferably, the aroma reservoir has a U-shaped section, the U having or not having two symmetrical legs, with these two legs of the U oriented downwards, when the reservoir is placed around the neck of this bottle.

[0026] Preferably, the aroma reservoir has a U-shaped section, the U having or not having two symmetrical legs.

[0027] One leg of the U is placed outside the neck of the bottle, so as to be able to diffuse the aroma through the external orifices, while the other leg of the U is placed inside the neck of the bottle, so as to be able to diffuse the aroma through the internal orifices.

[0028] Preferably, the first orifices on the one hand and the second orifice or orifices on the other hand are connected to the same chamber of the reservoir, this same chamber containing the same aroma to be diffused.

[0029] Thus, the user only smells one and the same aroma, but the sensation is amplified tenfold because it is felt simultaneously by breathing and by retro-nasalization.

[0030] Preferably, the first orifices on the one hand and the second orifice or orifices on the other hand are connected to two distinct chambers separated from the reservoir, these two distinct and separate chambers respectively containing two aromas to be diffused which are different from each other.

[0031] Thus, the user can simultaneously smell the mixture of two different perfumes in his nasal cavity, one arriving by breathing through the front of his nasal cavity and the other arriving by retro-nasalization through the back of his nasal cavity.

[0032] By playing with the dosage of the mixture, different interesting sensations can be provided to the user.

[0033] Preferably, the reservoir and / or diffuser is annular in shape, making a complete turn. Once placed around the neck of the bottle, the annular-shaped reservoir and / or diffuser makes a complete turn around the neck of the bottle.

[0034] Thus, the reservoir and the diffuser are positioned around the neck of the bottle in a more stable manner.

[0035] Preferably, the reservoir and / or diffuser is partially annular in shape, making between 60% and 90% of a complete turn.

[0036] 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.

[0037] This tamper-evident ring refers to the European directive on single-use plastics, known as the "captive cap" directive, which applies to all plastic bottle caps that must be attached to the bottle body from July 3, 2024. The objective of this regulation is to minimize the harmful effects of plastic on the environment. In this context, standardization of captive caps is planned, thus ensuring that the cap is collected and recycled with the bottle. To date, among the various captive cap solutions on the market, we find, in particular, caps attached to a base clipped under the threads (such as, for example, the "Rozanna" brand ("registered trademark")) and hinged "snap" caps (such as, for example, the "Cristalline" brand ("registered trademark")), which do not unscrew but open from the bottom up.

[0038] Preferably, the aroma diffusion orifices are regularly distributed around the axis of the annular or partially annular shape.

[0039] 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.

[0040] Preferably, the aroma diffusion orifices are of at least 4, or at least 6, or at least 10.

[0041] 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.

[0042] Preferably, the diffuser includes one or more tank shutters, first orifices and / or second orifice(s), this shutter or at least one of these tank shutters is movable relative to the tank by rotation around an axis of rotation parallel to the axis of the annular or partially annular shape.

[0043] Thus, a simple rotating gesture by the user allows the aroma to be released outside the reservoir containing the aroma of the diffuser.

[0044] In addition, the opening and closing positions of the shutter are even more stable.

[0045] Preferably, the diffuser includes one or more tank shutters, first orifices and / or second orifice(s), this shutter or at least one of these tank shutters is movable relative to the tank by translation along a translation axis parallel to the axis of the annular or partially annular shape.

[0046] Thus, a simple translational gesture by the user allows the aroma to be released outside the aroma reservoir of the diffuser.

[0047] Moreover, the shutter opening and closing mechanism is even simpler.

[0048] Preferably, the diffuser comprises a single reservoir shutter, both of the first orifices and of the second orifice(s), this reservoir shutter is movable relative to the reservoir, advantageously either by rotation around an axis of rotation parallel to the axis of the annular or partially annular shape, or by translation along an axis of translation parallel to the axis of the annular or partially annular shape.

[0049] 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.

[0050] Thus, the diffuser is positioned around the neck of the bottle in an even more stable manner.

[0051] Preferably, part of the clips or each clip is formed by a narrowing of material located between its distal part and its proximal part.

[0052] Thus, the mechanical realization of the diffuser clip(s) is made even simpler.

[0053] 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.

[0054] Thus, the diffuser is positioned even more stably around the neck of the bottle. Positioning the diffuser in its clipped / locked 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 collar as it moves towards locking, and when the diffuser is pulled from its locked position to its unlocked position, it resists retraction up to a certain force.

[0055] Preferably, the shutter is a flap made of elastomeric polymer material and can adopt two different reversible equilibrium positions, concave and convex. In the open equilibrium position, the flap adopts an upward concave posture, thus exposing the reservoir orifices, and in the closed equilibrium position, the flap adopts a downward convex posture, thus covering the reservoir orifices. The flap is annular and is fixed around the periphery of the upper face of the reservoir. "Upward" and "downward" refer to two opposite directions, corresponding to the diffuser installed around the neck of the bottle, relative to the top and bottom of the bottle when placed upright on a flat surface.

[0056] In its concave equilibrium position, when a predetermined closing force is applied by the user, the nature and properties of the flap material cause the flap to pivot into a second convex equilibrium position, such that the outer edges of the flap are pressed against the outer wall of the tank, thus covering its orifices. This embodiment provides the shutter with the advantages of ease of use, stability of the equilibrium positions, and improved airtightness of the shutter in the closed position. The elastomer material ensures smooth and durable reversibility between the equilibrium positions.

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

[0058] Thus, the aroma reservoir, once empty, 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 it of 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 sustainability is ensured. of the diffuser and its various components. 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 fasteners are regularly 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 are at least 2, or at least 3, or at least 4, or at least 6 fasteners.

[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, located around the neck of the bottle, to which the cap remains attached even once unscrewed from the neck, the cap can be removed from the neck without being hindered by the presence of the reservoir, whether the connection between the safety ring on the one hand and the cap on the other hand is short, of intermediate length, or long.

[0065] Preferably, the aroma reservoir is a replaceable consumable that is detachable from the rest of the aroma diffuser.

[0066] 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.

[0067] Preferably, the aroma is a fruity fragrance.

[0068] Thus, the sensation of drinking water becomes even more pleasant for the user.

[0069] Preferably, the aroma includes a component which has an effect of: either appetite suppression, taste desensitization, or taste re-education.

[0070] Thus, the simple act of drinking water can improve or even restore other sensations useful to the user.

[0071] Preferably, the aroma comprises 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.

[0072] 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 this essential oil.

[0073] Preferably, at least the reservoir, and preferably also the diffuser, is made or are made of natural cellulose.

[0074] Thus, the reservoir and / or diffuser are cheaper and more environmentally friendly, because they are more easily recyclable.

[0075] Preferably, the shutter is a flap made of elastomeric polymer material and can adopt two different reversible equilibrium positions, concave and convex. In the open equilibrium position, the flap adopts an upward concave posture, thus exposing the reservoir orifices, and in the closed equilibrium position, the flap adopts a downward convex posture, thus covering the reservoir orifices. The flap is annular and is fixed around the periphery of the upper face of the reservoir. "Upward" and "downward" refer to two directions opposite to each other, corresponding to the diffuser installed around the neck of the bottle, relative to the top and bottom of the bottle when placed upright on a flat surface.

[0076] Thus, with a simple gesture, the shutter switches between its open and closed positions, without risking remaining in an intermediate position between its open and closed positions, in a simple and efficient manner.

[0077] Preferably, the reservoir comprises at least two compartments which can release their respective aromas sequentially or alternately or jointly.

[0078] Thus, the release of the respective aromas from the two compartments is: • either sequential, with the aroma being the same in both compartments, which allows the aroma to last longer and retain its freshness and organoleptic qualities for longer, • or alternatively, the aromas being different between the two compartments, allowing the user to alternate the aroma over time, for example switching from strawberry to orange, • either joint, with different aromas between the two compartments, allowing the user to mix the two aromas together in their nasal cavity, for example combining strawberry perfume with mint perfume.

[0079] 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 from the user's hand or fingers on the reservoir during the first use.

[0080] Thus, the aroma is only released during the first use, thereby better preserving its freshness and organoleptic qualities before its use, and moreover in a simple and effective way.

[0081] Taste receptors can only register five distinct tastes, whereas there are hundreds of types of olfactory receptors that allow the nose to know There are many more scents. However, drinking flavored water from a bottle does not involve direct olfaction, but only retronasal olfaction. The invention also improves this drawback.

[0082] The disposable water bottle is preferably a disposable mineral water bottle, in particular a plastic water bottle. The disposable plastic water bottle can be replaced, for example, by a disposable bioplastic water bottle, or by a disposable bamboo water bottle, or by a disposable PLA water bottle.

[0083] The disposable water bottle is preferably recyclable or at least partly recyclable.

[0084] The disposable water bottle is opposed, for example, to a constantly reusable water bottle.

[0085] Advantageously, the aroma may emanate from a substance contained within it, known for its aromatic properties. The constituents or ingredients of the aromatizing material or substance contained in the reservoir chamber of the aroma diffuser will not be detailed herein. 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 contents of this chamber may contain ingredients in the form of solid granules, one or more gels, or one or more breakable capsules. The contents of this chamber may also include another constituent that can not only improve the diffusion of an aroma, but also, in particular, improve its preservation and / or aeration. Brief description of the drawings

[0086] 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.

[0087] [Fig-1] Fig. 1 schematically represents a side view of a device of a beverage comprising an aroma diffuser according to the invention. Bottle 1 is a disposable water bottle, in particular a disposable plastic water bottle, with a capacity of between 0.2 and 2 liters.

[0088] In the following description of embodiments of the invention, a container, for example a bottle, such as the one shown in the figure, 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.

[0089] Similarly, the expression "internal surface" refers to the surface of a part directed towards the inside of the bottle, and similarly, the expression "external surface" This refers to the surface of a part directed outwards from the bottle, that is, in a direction substantially opposite to the direction of the inside of the bottle. Similarly, 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.

[0090] Water bottles with a slightly shorter neck (17mm instead of 21mm), a steeper screw thread, and threads that only go around twice instead of three times around the neck of the bottle can also be used.

[0091] According to 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.

[0092] Once the capsule is broken, it releases its contents, but of course, these will remain in the reservoir as long as the diffuser is in the closed position. According to one variant, such a capsule can also be fitted in another location on the diffuser, in addition to the aroma extracts present in the reservoir.

[0093] 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.

[0094] At the ends of this guide, one or more end stops are provided, in translation and / or in rotation of the tank so as not to rotate in a vacuum.

[0095] The use of retronasal olfaction, in addition to direct olfaction, ensures a maximum sensory experience since all olfactory receptors (direct and retronasal) are stimulated at the same time.

[0096] Olfaction, on the other hand, occurs in two ways: direct (or ortho-nasal) and indirect (or retro-nasal).

[0097] Direct olfaction occurs when we directly inhale or smell the odor of uningested food, while retronasal olfaction occurs when aromas follow a trajectory passing behind the palate to return to the nasal cavities (and thus reach the olfactory epithelium in the nasal cavities).

[0098] 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.

[0099] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0100] Figure 1 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention. Bottle 1 is a disposable water bottle, in particular a disposable plastic water bottle, with a capacity of between 0.2 and 2 liters.

[0101] The aroma reservoir 5 includes a chamber 59 and aroma diffusion orifices 6, among which are several first aroma diffusion orifices 61, as well as a second orifice or several second aroma diffusion orifices 62.

[0102] The first orifices 61 are oriented outwards from the annular shape of the reservoir 5, i.e. the annular shape of the reservoir 5, and even towards the space above the reservoir 5. The reservoir 5 could also include other first orifices 61 in the outermost concentric wall 66 of the annular shape of the reservoir 5 which would then also be oriented outwards from the annular shape of the reservoir 5, and even towards the space around the reservoir 5.

[0103] The second orifice 62 or the second orifices 62 is oriented or are oriented towards the interior of the annular shape of the reservoir 5, that is to say towards the space 44 located inside the annular shape presented by the reservoir 5, that is to say again towards the space 44 located at the center of the annular shape of the reservoir 5, that is to say finally towards the space 44 located inside or at the center of the innermost concentric wall 64 of the reservoir 5.

[0104] The reservoir 5 includes several first aroma diffusion orifices 61, then arranged around the neck 4 of this bottle 1, oriented outwards from the neck 4 of this bottle 1, so as to permit aroma diffusion out of the reservoir, 5 around the neck 4 of this bottle 1, outwards from the neck 4 of this bottle 1, towards the top of this bottle 1, so that the diffused aroma can be absorbed, by breathing through the nose, by a user drinking the mineral water from this bottle 1.

[0105] The reservoir 5 includes a second orifice 62 or several second aroma diffusion orifices 62, then oriented(s) towards the inside of the neck 4 of this bottle 1 or oriented(s) towards the inside of the space 42 located above the neck 4 and in the extension of the neck 4 of this bottle 1, so as to allow aroma diffusion out of the reservoir 5, towards the inside of the neck 4 of this bottle 1 or oriented(s) towards the inside of the space 42 located above the neck 4 and in the extension of the neck 4 of this bottle 1, so that the diffused aroma can be absorbed, by retronasalization, by a user drinking the mineral water from this bottle 1.

[0106] In one option, the aroma reservoir 5 includes only one second aroma diffusion orifice 62, either oriented towards the inside of the neck 4 of this bottle 1 or oriented towards the inside of the space 42 located above the neck 4 and in line with the neck 4 of this bottle 1. Thus, retronasalization is satisfactorily achieved with a minimum number of diffusion orifices, here only one, because on the internal side, the fingers of the user's hand, whatever their position, cannot interfere with the aroma diffusion.

[0107] The aroma reservoir 5 comprises two or more concentric cylindrical walls, the second orifice 62 or second orifices 62 for diffusion of aroma, then oriented(s) towards the inside of the neck 4 of this bottle 1 or oriented(s) towards the inside of the space 42 located above the neck 4 and in the extension of the neck 4 of this bottle 1, belongs or belong to the innermost concentric cylindrical wall 64 of the reservoir 5. Thus, retro-nasalization is obtained satisfactorily, without risk of the liquid exiting through the neck 4 of the bottle 1 entering the aroma reservoir 5, even though the aroma exits through the internal orifice(s) 62 to enter the flow of liquid through the neck 4 going from the inside of the bottle 1 towards the inside of the user's mouth.

[0108] The aroma reservoir 5 has a generally annular shape with a U-shaped cross-section. The U has two asymmetrical legs 58, with these two legs 58 of the U oriented downwards when the reservoir 5 is placed around the neck 4 of the bottle 1. The inner leg 58a is inserted inside the neck 4, while the outer leg 58b is inserted outside the neck 4. The two legs 58a and 58b are connected by a horizontal portion 57, which has a three-dimensional crown shape. The outer leg 58b of the U is positioned outside the neck of the bottle so as to diffuse the aroma through the external orifices 61, while the inner leg 58a of the U is positioned inside the neck 4 of the bottle 1 so as to diffuse the aroma through the internal orifices 62.

[0109] In one option, the first orifices 61 on the one hand and the second orifice 62 or the second orifices 62 on the other hand are connected to the same chamber 59 of the reservoir, this same chamber 59 containing the same aroma to be diffused. Thus, the user smells only one and the same aroma, but the sensation is intensified because it is felt simultaneously by inhalation and retronasal inhalation.

[0110] In another option, the first orifices 61 on the one hand and the second orifice 62 or the second orifices 62 on the other hand are connected to two separate chambers in the reservoir 5, these two separate chambers each containing two different aromas to be diffused. Thus, the user can simultaneously experience a mixture of two different fragrances in their nasal cavity, one arriving by inhalation through the front of their nasal cavity and the other arriving by retronasal inhalation through the back of their nasal cavity. By adjusting the concentration of the mixture, the user can be provided with various interesting sensations.

[0111] In one option, the diffuser 2 may include one or more shutters 7 for the reservoir 5, the first orifices 61, and / or the second orifice(s) 62. This shutter 7, or at least one of these shutters 7, is movable relative to the reservoir 5 by rotation about an axis of rotation parallel to the Z-axis of the annular or partially annular shape of the reservoir 5 of the diffuser 2. Thus, a simple rotational movement by the user allows the aroma to be released. of the reservoir 5 containing the aroma of the diffuser. In addition, the opening and closing positions of the shutter 7 are even more stable.

[0112] In another alternative option, the diffuser 2 includes one or more shutters 7 for the reservoir 5, the first orifices 61, and / or the second orifice(s) 62. This shutter 7, or at least one of these shutters 7 for the reservoir 5, is movable relative to the reservoir 5 by translation along a translation axis parallel to the Z-axis of the annular or partially annular shape of the reservoir 5 of the diffuser 2. Thus, a simple translational movement by the user allows the aroma to be released from the reservoir 5 containing the aroma of the diffuser. Furthermore, the opening and closing mechanism of the shutter 7 is even simpler.

[0113] On [Fig. 1], a cylindrical water bottle 1 terminates upwards, along the Z axis, with a neck 4 of the bottle 1 also cylindrical having an external thread 40 of the neck 4 surrounding the neck 4, external thread 40 under which is a collar 41 of the neck 4 which is annular. 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 a locking ring 30, also annular, which is connected by a tab-type locking link (not shown in Fig. 1) 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 locking ring 30 also encircles the neck 4.The neck 4 terminates 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.

[0114] 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 arranged on the inner side wall 64 of the reservoir 5 (as seen in [Fig. 1], these are the second orifices 62) and on the upper wall 65 of the reservoir 5 (as also seen in [Fig. 1], these are the first orifices 61). The orifices 6, that is to say the first orifices 61 and the second orifices 62, of the reservoir 5, can be opened or closed by a movable obturator 7.

[0115] The opening 43 of the neck 4 is closed by a screw cap 3 which is shown in the unscrewed position on the [Fig.1].

[0116] The obturator 7 is movable, relative to the reservoir 5, between, on the one hand, a position of simultaneous closure of all the orifices 6, including the first orifices 61 and the second orifices 62, thus preventing the diffusion of aroma out of the reservoir 5, and on the other hand a position of simultaneous opening of all the orifices 6, including the first orifices 61 and the second orifices 62, allowing the diffusion of aroma out of the reservoir 5, on the one hand around the neck 4 of the bottle 1, and on the other hand also towards the top of this bottle 1.

[0117] The movable shutter 7 may include orifices (not shown in [Fig. 1]). For the movable shutter 7 to function, the cap 3 must first be unscrewed and removed from the neck 4 of the bottle 1.

[0118] In a first embodiment of the movable shutter 7, to obtain a position of simultaneous closure of all the orifices 6 (corresponding to that shown in [Fig. 1]), including the first orifices 61 and the second orifices 62, thus preventing the diffusion of aroma out of the reservoir 5, it is sufficient to have slid the single movable shutter 7 downwards along the vertical axis Z to the position shown in [Fig. 1]. The movable shutter 7 then has no orifices, the solid walls 75 and 74 of the movable shutter 7 covering and thus closing the diffusion orifices 6 of the reservoir 5, the upper wall 75 of the movable shutter 7 covering and closing the first orifices 61 of the upper wall 65 of the reservoir 5, and the lateral wall 74 of the movable shutter 7 covering and closing the second orifices 62 of the inner side wall 64 of the tank 5.Similarly, to obtain a position of simultaneous opening of all the orifices 6 (corresponding to that shown in [Fig.1]) including the first orifices 61 and the second orifices 62, thus allowing the diffusion of aroma out of the reservoir 5, it is sufficient to slide in translation the single movable shutter 7 upwards along the vertical axis Z from the position shown in [Fig.1], the movable shutter 7 then having no orifices, the solid walls 75 and 74 of the movable shutter 7 then cease to cover and thus open the diffusion orifices 6 of the reservoir 5. In fact, the single shutter 7 of the reservoir is movable relative to the reservoir 5 by translation along a translation axis Z parallel to the axis of the annular or partially annular shape of the reservoir 5.

[0119] In a second embodiment (not shown in [Fig. 1]), the position corresponding to a simultaneous opening of all the orifices 6, including the first orifices 61 and the second orifices 62, thus allowing aroma diffusion out of the reservoir 5, corresponds to the movable shutter 7 located around the reservoir 5, with orifices (not shown in [Fig. 1]) positioned opposite the diffusion orifices 6 of the reservoir 5. To obtain the position corresponding to a simultaneous closing of all the orifices 6, including the first orifices 61 and the second orifices 62, thus preventing aroma diffusion out of the reservoir 5, it is sufficient to rotate the single movable shutter 7 around the vertical axis Z (without modify its position along the vertical axis Z), so that its orifices are no longer arranged opposite the diffusion orifices 6 of the reservoir 5, so that solid portions of the perforated walls 75 and 74 of the movable shutter 7 cover and thus close the diffusion orifices 6 of the reservoir 5, both a solid portion of the upper wall 75 of the movable shutter 7 then covering the first orifices 61 located in the upper wall 65 of the reservoir 5 and a solid portion of the lateral wall 74 of the movable shutter 7 then covering the second orifices 62 located in the inner lateral wall 64 of the reservoir 5. The second embodiment resembles a salt shaker-type mechanism with a rotating lid. In fact, the single obturator 7 of the reservoir 5 is movable relative to the reservoir 5 by rotation around an axis of rotation Z parallel to the axis of the annular or partially annular shape of the reservoir 5.

[0120] The movable shutter 7 can cover and thus close the diffusion orifices 6 of the reservoir 5, whether it is the second orifices 62 which are located on the inner side wall 64 of the reservoir 5 or whether it is the first orifices 61 which are located on the upper wall 65 of the reservoir 5, it is sufficient for this that the movable shutter has a cylindrical shape extended by an annular face, and that the movable shutter 7 moves in translation or in rotation.

[0121] The first orifices 61 are external and arranged 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 obturator 7 of the reservoir 5, movable, relative to the reservoir 5, between an opening position of this or these first external orifices 61 and a closing position of this or these first external orifices 61. Thus, the single movement of a single element, the obturator 7, makes it possible to open or close all the first external orifices 61 at the same time.

[0122] The second orifices 62 are internal and arranged so as to allow the diffusion of aroma out of the reservoir 5, inside the neck 4 of this bottle 1, the obturator 7 of the reservoir 5, movable, relative to the reservoir 5, between an opening position of this or these second internal orifices 62 and a closing position of this or these second internal orifices 62. Thus, the single movement of a single element, the obturator 7, allows all the second internal orifices 62 to be opened or closed at the same time.

[0123] This [Fig.1] schematically represents a profile view of a beverage device comprising an aroma diffuser according to the invention, with a first type of preferential attachment of the aroma diffuser to the beverage device, other types of attachment also being conceivable.

[0124] 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 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 position 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 both easy installation of the diffuser 2 around the neck 4, and good blocking in translation along the vertical axis Z, so that the diffuser does not slide along the vertical axis Z when the bottle 1 is inverted (neck 4 oriented obliquely but rather downwards) and the user is drinking, so as not to hinder the user in the action of drinking.The application by the user of a limited but deliberate effort makes it possible to unlock the clips 80 and release the collar 41, the diffuser then being able to move freely up towards the top of the neck 4, because the collar 41 has the largest outside diameter of the neck 4, namely an outside diameter which is on the one hand larger than the outside diameter of the safety ring 30 and which is on the other hand larger than the maximum outside diameter of the external thread 40 of the neck 4. .

[0125] The clips 80 are regularly distributed around the Z-axis of the annular or partially annular shape. Thus, the diffuser 2 is positioned around the neck 4 of the bottle 1 in an even more stable manner.

[0126] There are at least 2, or at least 3, or at least 4, or at least 6 clips 80. Thus, the diffuser 2 is positioned around the neck 4 of the bottle 1 in an even more stable manner.

[0127] 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 on the collar, so as to clamp this collar 41 between them, so as to place 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, intermediate, or long.

[0128] 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 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.

[0129] In another option, the reservoir 5 and / or the diffuser 2 is partially annular in shape, making between 60% and 90% of a complete rotation around their axis. Thus, a A good compromise is achieved 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 clearance space of sufficient size, in the empty part where the missing part (the hole) of the annular shape is located, is arranged to receive the cap 3 once 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.

[0130] The first aroma diffusion orifices 61 in the upper wall 65 of the reservoir 5 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 aroma diffusion 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 first diffusion orifices 61 could be temporarily blocked by one or more fingers of the user covering them at that time.

[0131] The first aroma diffusion orifices 61 in the upper wall 65 of the reservoir 5 are at least 4, or at least 6, or at least 10 in number. Thus, regardless of the position of the fingers of the user 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, regardless of the position of the user's fingers. The second aroma diffusion orifices 62 in the inner side wall 64 of the reservoir 5 are, for example, 2 in number; there could also be only one.

[0132] 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 for society. The consumer then only has to replace the reservoir 5, which can be sold separately as a replaceable consumable, after repeated use has depleted it of its aroma. This aroma reservoir 5 can be marketed with packaging covering 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.

[0133] In one option, the aroma is a fruity fragrance. Thus, the sensation of drinking water becomes even more pleasant for the user.

[0134] In another option, the flavoring includes a component that has an effect: either appetite-suppressing, taste desensitizing, or taste-retraining. Thus, the simple act of drinking water enhances or even restores other sensations useful to the user. Preferably, the flavoring includes at least one component and / or at least one essential oil, of one or more of the following scents: peppermint, lemon, grapefruit, cinnamon, rosemary, clove, green mandarin, thyme. Thus, the simple act of drinking water triggers other beneficial effects in the user, beyond pleasure, at the cost of a very limited inhalation of essential oil vapor, instead of having to actually drink a few drops of that essential oil.

[0135] In one option, at least the reservoir 5, and preferably also the diffuser 2, is or are made of natural cellulose. Thus, the reservoir 5 and / or the diffuser 2 are less expensive and more environmentally friendly, as they are more easily recyclable.

[0136] In one option, the reservoir 5 has at least two compartments that can release their respective aromas sequentially, alternately, or simultaneously. The movable shutter 7 then has several positions: a first position in which the diffusion orifices 6 of all compartments are closed; and / or a second position in which the diffusion orifices 6 of a first compartment are opened while simultaneously closing the diffusion orifices 6 of a second compartment; and / or a third position in which the diffusion orifices 6 of the second compartment are opened while simultaneously closing the diffusion orifices 6 of the first compartment; and / or a fourth position in which the diffusion orifices 6 of all compartments are open. Thus, the release of the respective aromas from the two compartments is: • either sequential, with the aroma being the same in both compartments, which allows the aroma to last longer and retain its freshness and organoleptic qualities for longer, • or alternatively, the aromas being different between the two compartments, allowing the user to alternate the aroma over time, for example switching from strawberry to orange, • either joint, with different aromas between the two compartments, allowing the user to mix the two aromas together in their nasal cavity, for example combining strawberry perfume with mint perfume.

[0137] In one option, the first compartment can be arranged to include both first orifices 61 and second orifices 62, while the second compartment can also be arranged to include both first orifices 61 and second orifices 62. In an alternative option to the previous option, the first compartment can be arranged to include only first orifices 61 but no second orifices 62, while the second compartment can also be arranged to include only second orifices 62 but no first orifices 61.

[0138] In one option, the diffuser 2 contains a capsule of flavoring liquid or gel, this capsule being made of a sufficiently brittle material, and the reservoir 5 being 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 material of the capsule, so that reasonable pressure from the hand of an adult user on the reservoir 5 transmits enough force to break the capsule contained in the reservoir 5. Thus, the flavor is released only during the first use, thereby better preserving its freshness and organoleptic qualities before use, and moreover in a simple and effective manner.
