[0001] Description

[0002] Title: Aroma diffuser for disposable water bottle

[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

[0006] In the realm of non-alcoholic beverages, the main options are water, fruit juices, and sodas. The challenge lies in reconciling two distinct, often contradictory, aspects: the consumer's taste and their health.

[0007] 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.

[0008] Water is excellent for your health, but many people find it too bland, whether still or sparkling. Fruit juices might seem like a good middle ground between sodas and water, striking a balance between taste and consumer health. But here again, the compromise is far from perfect, because either the amount of fruit juice is high, and the drink tastes good but is still too sweet, or the amount of fruit juice is low, and the drink becomes less harmful to your 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 (figures 5 and 6), a water bottle associated with an aroma diffuser located at the bottle cap is known, formed of an absorbent material (44) and a pouch (48) of liquid aroma (50), but it requires a specific cap structure dedicated to a specific form of aroma diffuser.

[0012] Furthermore, with regard to this prior art, the invention has highlighted that the manufacturing process for this stopper incorporating an aroma pouch is complex and delicate, as it requires several difficult steps: First, the attachment of a very elongated pouch to the bottom of the stopper, precisely centered to ensure that the aroma pouch opens when the user presses it with their finger; Second, the installation, on this pouch, of a layer of absorbent material, which must not press too hard on the pouch, lest it open; This layer does not rest against the bottom of the stopper, but is instead fixed only to the cylindrical circumference of the stopper, securely attached, otherwise the liquid aroma will leak from the absorbent material, seeping between this absorbent material and the cylindrical circumference of the stopper from the open pouch located between the bottom of the stopper and this absorbent material; Finally,When the user presses on the absorbent material to puncture the aroma pouch, the thin, narrow attachment of the absorbent material to the cylindrical rim of the cap must not break, tear, or detach. Otherwise, the liquid aroma will leak from the absorbent material, seeping between it and the cylindrical rim of the cap from the open pouch located between the base of the cap and the absorbent material. Therefore, the manufacturing process is complex and delicate to create this sandwich-like structure, comprising the base of the cap, the elongated and well-centered pouch, and the layer of absorbent material attached only to the cylindrical rim of the cap, with good quality: firstly, to ensure the aroma pouch opens properly, and secondly, to prevent leakage of liquid aroma between the absorbent material and the cylindrical rim of the cap.

[0013] 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.

[0014] OBJECTS OF THE INVENTION

[0015] The invention offers an alternative approach to solving this problem. The invention provides an aroma diffuser whose design, shape, and structure allow for direct use with a commercially available bottle of mineral water, without any modification to the bottle's shape or structure. The aroma is released as the user drinks the water from the bottle. Thus, the aroma diffuser offers users simplicity and flexibility in its use, while also allowing them to save money.

[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] The invention makes the following choices: On the one hand, to retain the good idea of ​​having a pouch or capsule that only opens during use, by pressing it with one or more fingers of the user's hand, thus preventing premature loss of aroma and the need to use too many pouches or capsules of aroma to obtain a sufficient olfactory sensation for the user, i.e., the person who will drink the water from the bottle. But on the other hand, to integrate this pouch or capsule, or these pouches or capsules of liquid aroma, inside the absorbent material. This material can then be manufactured completely outside the bottle, thus with a manufacturing process that can be optimized separately from the bottle and its cap. The entire assembly, formed by the absorbent material including the capsule (located inside the absorbent material), is much easier to handle and install in or on a support. And finally,to install the entire assembly formed by the absorbent material, including the capsule (located inside the absorbent material), in an annular or partially annular aroma reservoir, more precisely in the hollow body forming this annular or partially annular aroma reservoir, so that this reservoir can be very easily slid in by the user just before use, either vertically, i.e. parallel to the vertical axis of the bottle placed on a flat horizontal surface, or horizontally, i.e. orthogonally to the vertical axis of the bottle placed on a flat horizontal surface.

[0018] 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, comprising: a hollow body: of annular or partially annular shape so as to be able to be placed around the neck of this bottle, under the collar, and comprising one or more aroma diffusion orifices, an absorbent material suitable: for containing at least one aroma in liquid form, for diffusing this aroma in gaseous form out of the absorbent material and out of the hollow body through all or part of the aroma diffusion orifices, at least one aroma capsule, comprising a closed outer shell, containing an aroma in liquid form, being suitable for opening, preferably by tearing, bursting, or breaking.so that the aroma spreads into the absorbent material by simply applying pressure to a part of the aroma reservoir, the aroma capsule being located inside the absorbent material which is surrounded by the hollow body.

[0019] 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: a neck, surrounded by a thread for a screw cap, and by a collar, located under the thread of the neck, an aroma diffuser according to the invention.

[0020] The present invention thus makes it possible to overcome the drawbacks of known devices, by providing a diffuser: - providing the consumer with a perceived flavor 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 Nutri-Score™ scale,

[0021] - 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.

[0022] 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.

[0023] Preferably, the aroma diffuser also includes: at least one reservoir shutter, movable, relative to the reservoir, between: a position of simultaneous closure of all or part of the orifices, preventing the diffusion of aroma out of the reservoir, and a position of simultaneous opening of all or part of the orifices, allowing the diffusion of aroma out of the reservoir, around the neck of this bottle, towards the top of this bottle.

[0024] Thus, even once the capsule is opened, and the liquid aroma from this opened capsule is dispersed into the absorbent material, or into the layer of absorbent material, this liquid aroma will not diffuse in gaseous form to no avail, when the user does not drink and has put down their water bottle, because then, during these pause periods, between two actions of drinking, the user will have closed the aroma reservoir using the shutter, thus avoiding a gaseous diffusion of aroma during these pause periods.

[0025] Preferably, the tank's obturator is movable, relative to the tank, between: a first stop corresponding to the position of simultaneous closure of all or part of the orifices, and a second stop corresponding to the position of simultaneous opening of all or part of the orifices.

[0026] Thus, the transition between the closed and open positions of the orifices is made more simply by the user, who will therefore be more inclined to close the orifices at each pause, when he is not drinking, as this closure, and the opening which follows, are made easier and simpler to perform.

[0027] Preferably, the reservoir shutter is arranged so as to open the or part of the aroma capsules by the movement of this shutter coming into contact with said or said aroma capsules.

[0028] Thus, the first opening of the shutter or the first closing of the shutter will simultaneously open the capsule and diffuse the liquid aroma contained in the capsule into the absorbing material, resulting in: on the one hand, a simplification and reduction of the user's actions, and on the other hand, a simplification of the structure of the aroma diffuser and a reduction in the number of moving parts in the aroma diffuser.

[0029] Preferably, the aroma capsule(s) or part thereof protrude out of the orifices towards the outside of the reservoir, the reservoir closure is arranged so as to open the aroma capsule(s) or part thereof by the movement of this closure, when all or part of the orifices are simultaneously closed, by opening the aroma capsule(s) or part thereof protruding out of the orifices towards the outside of the reservoir.

[0030] Thus, the contact and the constraint exerted by the shutter itself on the part of the capsule(s) which protrudes and is therefore in the direct path of the shutter's trajectory, will allow the opening of the capsule which will then advantageously break, tear or burst under the force exerted by the body of the shutter.

[0031] Preferably, the aroma capsule(s) or part thereof are located at the level of all or part of the orifices but do not protrude out of the orifices towards the outside of the reservoir, the reservoir closure includes at least one protrusion directed towards the inside of the reservoir, the reservoir closure is arranged so as to open the aroma capsule(s) or part thereof by the movement of this closure, when all or part of the orifices are closed simultaneously, the protrusion of the closure then opening the aroma capsule(s) or part thereof by passing over them.

[0032] Thus, the contact and the constraint exerted by a protrusion protruding from the shutter on the part of the capsule(s) that protrudes and is therefore in the direct path of the shutter's trajectory, will allow the opening of the capsule which will then advantageously break, tear or burst under the force exerted by the protrusion protruding from the shutter.

[0033] Preferably, the hollow body has one or more areas of weakness: whose hardness is strictly less than, or at least 2 times less than, or at least 5 times less than, or at least 10 times less than, or at least 50 times less than, the hardness of the rest of the hollow body, which is or are respectively located opposite the aroma capsule or opposite the aroma capsules.

[0034] The weak point is typically a deformable or soft area that transmits the pressure exerted by a user's finger (to open the capsule), without necessarily opening or tearing itself. The weak point is often softer than the surrounding hollow body wall.

[0035] Hardness is conventionally measured in Shore units.

[0036] Thus, the simple pressure of one or more fingers of the user's hand on this or these areas of weakness will mechanically, automatically and directly cause the opening of the liquid aroma capsule(s), this or these aroma capsule(s) advantageously bursting, breaking or tearing under the effect of this pressure, thus releasing the aroma which spreads into the absorbing medium, before being diffused in gaseous form through the orifices of the aroma reservoir, that is to say through the orifices of the hollow body forming the aroma reservoir.

[0037] As an alternative to the weak point, a movable flap that can be opened and closed could be used and would function satisfactorily, but the structure of the hollow body of the aroma diffuser reservoir would then be somewhat more complex. In this alternative, the hollow body has one or more flaps that are movable between their open position, in which the absorbent material becomes accessible from outside the hollow body, and their closed position, in which the absorbent material remains inaccessible from outside the hollow body, and which are respectively located opposite the aroma capsule(s).

[0038] Preferably, the area(s) of weakness is / are impermeable to liquids.

[0039] Thus, the liquid aroma spreading in the absorbent material will not stain or even touch the finger of the user who pressed on the area(s) of weakness, which constitutes additional comfort for the user.

[0040] Preferably, the weak point(s) is / are made of fabric or rubber. The weak point is preferably impermeable to liquids, and may or may not be impermeable to gases.

[0041] Thus, this or these areas of weakness are simple and robust.

[0042] Preferably, the aroma capsule is unique.

[0043] Thus, the overall structure of the absorbent material is simpler.

[0044] Preferably, the aroma capsule is located in the middle of the perimeter of the annular or partially annular shape of the hollow body.

[0045] Thus, diffusion in the absorbent material located in the hollow body of the aroma reservoir, which is annular and partially annular in shape, is carried out more quickly and more uniformly.

[0046] Preferably, there should be at least two aroma capsules.

[0047] Thus, the space around the diffuser, into which the liquid aroma will then be diffused, is larger and / or the quantity of aroma diffused is greater.

[0048] Preferably, the aroma capsules are regularly distributed along the perimeter of the annular or partially annular shape of the hollow body, and / or the two aroma capsules or at least two of the aroma capsules are arranged at the ends of the only partially annular shape of the hollow body.

[0049] Thus, diffusion within the absorbent material located in the hollow body of the aroma reservoir, which is annular and partially annular in shape, occurs more rapidly and uniformly. Preferably, the orifices are oblong or elongated in shape, and the reservoir's closure is movable, relative to the reservoir, to at least one intermediate position between: on the one hand, the position of simultaneous closure of all or some of the orifices, and on the other hand, the position of simultaneous opening of all or some of the orifices, the orifices then being simultaneously partially closed and partially open, or simultaneously half-closed and half-open.

[0050] Thus, an additional option is offered to the user: the choice between a moderately intense and a highly intensely intense aroma release. This option of using a moderately intense aroma release may be particularly appealing to economical and / or environmentally conscious users who want to be able to reuse the same diffuser, its absorbent material, and its aroma capsule(s) multiple times—that is, with several bottles of water consumed consecutively.

[0051] In a first alternative, to easily and simply slide the aroma diffuser around the neck of the bottle, advantageously vertically from above, the aroma diffuser includes: one or more clips, 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.

[0052] The clip(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.

[0053] 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 and the cap is short, of intermediate length, or long.

[0054] 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.

[0055] Thus, the reservoir and diffuser are positioned more stably around the neck of the bottle. Preferably, the reservoir and / or diffuser is partially annular in shape, completing between 60% and 90% of a full rotation.

[0056] 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.

[0057] 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.

[0058] Preferably, the aroma diffusion orifices are regularly distributed around the axis of the annular or partially annular shape.

[0059] 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.

[0060] Preferably, there should be at least 4, or at least 6, or at least 10 aroma diffusion openings.

[0061] 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.

[0062] Preferably, the reservoir's shutter is movable relative to the reservoir by rotating around an axis parallel to the axis of the annular or partially annular shape. Thus, a simple rotating motion by the user releases the aroma from the diffuser's aroma reservoir.

[0063] Furthermore, the opening and closing positions of the shutter are even more stable.

[0064] Preferably, the tank's shutter slides into a hollow part of the tank.

[0065] Thus, the movement of the shutter is more stable because it is guided.

[0066] Preferably, the clips are evenly distributed around the axis of the annular or partially annular shape.

[0067] Thus, the diffuser is positioned around the neck of the bottle in an even more stable manner.

[0068] Preferably, there should be at least 2 clips, or at least 3, or at least 4, or at least 6.

[0069] Thus, the diffuser is positioned around the neck of the bottle in an even more stable manner.

[0070] Preferably, part of the clips or each clip is formed by a narrowing of material located between its distal and proximal parts.

[0071] Thus, the mechanical production of the diffuser clip(s) is made even simpler.

[0072] 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.

[0073] 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.

[0074] Preferably, the aroma is a fruity fragrance.

[0075] Thus, the sensation of drinking water becomes even more pleasant for the user. Preferably, the flavoring includes a component that has an effect: either appetite suppressant, taste desensitization, or taste retraining.

[0076] Thus, the simple act of drinking water can improve or even restore other sensations beneficial to the user. Preferably, the aroma includes at least one component and / or at least one essential oil, from one or more of the following fragrances: peppermint, lemon, grapefruit, cinnamon, rosemary, clove, green mandarin, thyme.

[0077] 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.

[0078] Preferably, at least the reservoir, and preferably also the diffuser, is or are made of natural cellulose.

[0079] Thus, the reservoir and / or diffuser are cheaper and more environmentally friendly, because they are more easily recyclable.

[0080] Preferably, the reservoir has at least two compartments that can release their respective aromas sequentially, alternately, or jointly.

[0081] 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.

[0082] 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.

[0083] The disposable water bottle is preferably a mineral water bottle, specifically a plastic water bottle. The plastic disposable water bottle can be replaced, for example, by a bioplastic disposable water bottle, a bamboo disposable water bottle, or a PLA disposable water bottle.

[0084] The disposable water bottle is preferably recyclable or at least partially recyclable.

[0085] A disposable water bottle, for example, is the opposite of a constantly reusable water bottle.

[0086] 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.

[0087] In a second alternative, to easily and simply slide the aroma diffuser around the neck of the bottle, advantageously horizontally from the side, the aroma reservoir of the aroma diffuser and / or the diffuser is or are partially annular in shape, making between 60% and 90% of a full turn, so as to be able to clip around the neck of this bottle, under the collar of the neck of this bottle.

[0088] The aroma reservoir is partially annular, forming between 60% and 90% of a full rotation, so that it can be clipped around the neck of the bottle, under the neck collar. This aroma reservoir comprises one or more chambers or compartments in which one or more aromas are stored. The aroma reservoir also includes a support for the chamber(s) or compartment(s). Either the chamber(s) or the entire assembly of chamber(s) or the entire assembly of compartment(s) is / are partially annular, forming between 60% and 90% of a full rotation.Either the chamber(s) or the compartment(s) are partially annular in shape, with each chamber forming between 60% and 90% of a full rotation, but its support is also partially annular, with each chamber forming between 60% and 90% of a full rotation, so that the diffuser, and therefore the reservoir, can be clipped around the neck of the bottle, under the collar of the bottle's neck. Towards its ends, the support may have a smaller cross-section, or at least half the cross-section, of the reservoir chamber(s) or the reservoir compartment(s). The diffuser as a whole is advantageously partially annular, with each chamber forming between 60% and 90% of a full rotation, so that it can be clipped around the neck of the bottle, under the collar of the bottle's neck.

[0089] 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.

[0090] 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 planned, 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 cap (registered trademark)) and hinged "snap" caps (such as the "Cristalline" brand cap (registered trademark)), which do not unscrew but open from the bottom up.

[0091] It is this partially annular shape, making more than half a turn but not a full turn, of the aroma reservoir that will allow this aroma reservoir to be clipped very simply and easily around the neck of the bottle, just under the collar of the neck of the bottle, the aroma reservoir then being held by the domed part of the body of the bottle flaring out under the collar of the neck of the bottle.

[0092] The collar is the last radial protrusion located around the neck of the bottle, towards the bottom of the bottle, before the body of the bottle, which flares radially outwards in a conical shape before reaching its maximum corresponding to the cylindrical section of the bottle with a constant or practically constant circular cross-section. By clipping around the neck of the bottle, the inner part of the annular shape of the reservoir is advantageously at least partially in contact with the neck itself, in the part where its external diameter is minimal.

[0093] The aroma reservoir can in particular be clipped in by a movement orthogonal to the vertical axis of the bottle, thanks to the elasticity (even reduced if the material constituting the wall of the reservoir is relatively rigid intrinsically) of the ends of the partially annular shape which will move away from each other when they meet the neck of the bottle, then will move closer together to partially encircle the neck of the bottle.

[0094] This partially annular shape allows, for a given shape and size of reservoir, in particular to adapt to a certain range of outside diameters of bottle neck, while maintaining a good compromise between the following two properties: the aroma reservoir can be clipped simply and easily around the neck of the bottle, the aroma reservoir remains around the neck of the bottle without falling, and advantageously without slipping or with very little slippage around the neck of the bottle, when the user of the bottle tilts the bottle from a vertical position to a horizontal or inclined position, in order to be able to drink the liquid (advantageously water) contained in the bottle.

[0095] The range of outside diameters can cover a few millimeters, for example, at least 4 mm or at least 6 mm (especially when the tank has an internal layer or inward protrusions, as considered in option(s) in Figure 3 below), but advantageously remain less than 10 mm, or advantageously less than 8 mm, around an average diameter. Preferably, the internal diameter of the partially annular shape of the tank is between 20 mm and 30 mm. Preferably, the internal diameter of the bottle neck is also between 20 mm and 30 mm.

[0096] This partially annular shape is advantageously a form of torus whose cross-section is, for example, circular or rectangular.

[0097] The overall shape of the diffuser itself can then be partially annular and torus-shaped, the cross-section of which is, for example, circular or rectangular.

[0098] The shape and size of both the aroma reservoir and the aroma diffuser can therefore be simple and small, respectively. Preferably, the reservoir and / or diffuser is partially annular in shape, forming between 65% and 85% of a full circle.

[0099] This reduced angular coverage range of the partially annular shape allows, for a given shape and size of a single reservoir, in particular to adapt to a certain range of outside diameters of bottle neck, while maintaining a better compromise between the following two properties: the aroma reservoir can be clipped simply and easily around the neck of the bottle, the aroma reservoir remains around the neck of the bottle without falling, and advantageously without slipping or with very little slippage around the neck of the bottle, when the user of the bottle tilts the bottle from a vertical to a horizontal or inclined position, in order to be able to drink the liquid (advantageously water) contained in the bottle.

[0100] Preferably, the reservoir and / or diffuser is or are partially annular in shape, making between 70% and 80% of a full turn.

[0101] This even smaller angular coverage range of the partially annular shape allows, for a given shape and size of a single reservoir, in particular to adapt to a certain range of outside diameters of bottle neck, while maintaining an even better compromise between the following two properties: the flavor reservoir can be clipped simply and easily around the neck of the bottle, the flavor reservoir remains around the neck of the bottle without falling, and advantageously without slipping or with very little slippage around the neck of the bottle, when the user of the bottle tilts the bottle from a vertical to a horizontal or inclined position, in order to be able to drink the liquid (advantageously water) contained in the bottle.

[0102] Alternatively, the reservoir and / or diffuser is or are partially annular in shape, making between 60% and 80% of a full turn, which allows the use of an aroma reservoir with a larger cross-section, where the largest dimension of the cross-section and the smallest dimension are in a maximum ratio of approximately 3 to 1, preferably in a maximum ratio of 2 to 1, and even more preferably in a maximum ratio of 1.5 to 1. Preferably, the smallest dimension of the cross-section of the aroma reservoir is between 30% and 100% of the largest dimension of the cross-section of the aroma reservoir, which maximizes the usable volume of the aroma reservoir for a given footprint of this aroma reservoir.

[0103] Preferably, the aroma reservoir is partially annular in shape and made of one or more materials sufficiently elastic to be able to clip around the neck of this bottle, under the collar of the neck of this bottle, by moving this aroma reservoir in a direction orthogonal to a vertical axis of the bottle.

[0104] Thus, the clipping is partially simple and easy to do.

[0105] Preferably, the aroma reservoir is partially annular in shape and made of one or more sufficiently elastic materials so that it can be clipped around the neck of this bottle, under the collar of the neck of this bottle, by moving this aroma reservoir in a direction perpendicular to a vertical axis of revolution symmetry of the bottle.

[0106] Thus, the clipping is partially simple and easy to do.

[0107] Preferably, the wall of the aroma reservoir is made of plastic.

[0108] Thus, the reservoir is sturdy and simple to manufacture, and its partially annular shape makes it sufficiently elastic to easily clip around the bottle neck, even though the plastic itself remains quite rigid, while still remaining securely clipped around the neck. This material is particularly well-suited when the partially annular shape is between 60% and 75% of a full circumference.

[0109] Preferably, the wall of the aroma reservoir is made of rubber.

[0110] Thus, the reservoir is particularly flexible, allowing it to easily clip around the neck of the bottle. This material is especially well-suited when the partially annular shape is between 75% and 90% of a full rotation.

[0111] Preferably, the aroma reservoir comprises either a single aroma chamber with multiple aroma diffusion holes or two aroma chambers, each with multiple aroma diffusion holes. This results in a simpler and more robust chamber structure, making it easier to fill with aroma during diffuser manufacturing, but the reservoir does have a certain volume. This is also true for a two-chamber design, though to a slightly lesser extent.

[0112] In the case of two chambers, it is even possible to mix two different aromas during aroma diffusion.

[0113] Preferably, the aroma reservoir includes several aroma compartments, each with a single aroma diffusion orifice.

[0114] Thus, the reservoir can be miniaturized more easily, but the compartments will become a little more difficult to simply fill with aroma during the manufacture of the diffuser.

[0115] Preferably, the tank obturator is partially annular in shape, making between 50% and 90% of a full turn, preferably making a portion of a full turn that is less than the portion of a full turn of the tank.

[0116] Thus, the movement of the shutter can easily correspond to a rotational kinematic.

[0117] Preferably, the tank obturator is partially annular in shape, making between 50% and 85% of a full turn, making a portion of a full turn that is less than that of the tank.

[0118] Thus, the movement of the shutter can easily correspond to a rotational kinematic.

[0119] Preferably, the tank closure includes openings and is movable relative to the tank between the closed position and the open position by rotation around the tank, between the closed position where its openings are offset from the aroma diffusion orifices and the open position where its openings are opposite the aroma diffusion orifices.

[0120] Thus, this rotational kinematics is more fluid to achieve than a translational kinematics would be.

[0121] Preferably, the tank's shutter is movable relative to the tank, between the closed and open positions, by rotation around the tank. This rotation occurs around an axis of rotation that passes through the center of the tank's annular shape and is orthogonal to the mean plane of the tank's annular shape. Thus, the shutter's movement corresponds to a sliding motion of an outer (partial) ring around an inner (partial) ring. This motion is very smooth.

[0122] Preferably, the shutter is made of plastic.

[0123] Thus, the sliding motion is more stable.

[0124] Preferably, the aroma reservoir includes one or more protrusions that are formed or fixed on the outer wall of the reservoir that are located inside the partially annular shape of the reservoir, and / or that are oriented towards the center of the partially annular shape of the reservoir.

[0125] Thus, the angular position of the reservoir (and also of the diffuser) around the neck of the bottle is made even more stable, even when the user of the bottle tends to shake the bottle a little when drinking the liquid (advantageously water) from this bottle.

[0126] Preferably, the aroma reservoir includes several protrusions that are regularly distributed around the partially annular shape of the reservoir, preferably between 2 and 5 protrusions.

[0127] Thus, the angular position of the reservoir (and also of the diffuser) around the neck of the bottle is made even more stable, even when the user of the bottle tends to shake the bottle a little when drinking the liquid (advantageously water) from this bottle.

[0128] Preferably, the protrusion(s) are made of textile, fabric, or rubber.

[0129] Thus, the higher friction of these materials helps to further stabilize the angular position of the reservoir (and also the diffuser) around the neck of the bottle.

[0130] Preferably, the absorbent material is in the form of foam or sponge.

[0131] Preferably, the absorbent material is capable of containing this aroma in liquid form or in solid form, which allows the aroma it has absorbed to diffuse in gaseous form.

[0132] Preferably, the ends of the annular shape of the aroma reservoir are extended, maintaining said annular shape, by clips with a cross-section smaller than that of the reservoir. These clips, extending the ends of the annular shape of the reservoir along its length, allow for a better grip on the bottle neck while still making it very easy to clip the container around the neck.

[0133] Preferably, the tank closure is movable relative to the tank by rotation around an axis of rotation parallel to the axis of the annular or partially annular shape.

[0134] Thus, a simple rotating gesture by the user allows the aroma to be released from the reservoir containing the aroma of the diffuser.

[0135] Furthermore, the opening and closing positions of the shutter are even more stable.

[0136] Preferably, the partially annular shape of the aroma reservoir is a torus whose cross-section can be circular or rectangular or of any closed shape.

[0137] The shape and size of both the aroma reservoir and the aroma diffuser can thus be respectively simple and reduced.

[0138] Preferably, the aroma diffuser has a partially annular shape which is preferably a torus whose cross-section may be circular or rectangular or of any closed shape.

[0139] The shape and size of both the aroma reservoir and the aroma diffuser can therefore be respectively very simple and very small.

[0140] Preferably, the height of the diffuser and / or the height of the reservoir is or are approximately equal to the distance between the neck flange and the conical shape of the bottle body. This ensures that the diffuser is positioned more stably, or even immobile, around the bottle neck. The height of the diffuser and the height of the reservoir are measured along the same vertical axis Z as the bottle itself.

[0141] Preferably, the absorbent material completely surrounds the capsule, or completely surrounds some of the capsules, or completely surrounds all the capsules, or the absorbent material is in contact with the entire outer surface of the closed outer shell of the capsule, or of some of the capsules, or of all the capsules.

[0142] Thus, once the capsule is opened, the diffusion of liquid aroma into the absorbent material is particularly rapid and uniform, eliminating or minimizing any leakage of liquid aroma to the outside of the absorbent material. Preferably, several capsules contain different aromas.

[0143] Thus, the richness of the diffused aromas, and / or the variability in the aroma diffusion sequence, is increased or are increased.

[0144] Preferably, the capsule or capsules each have a spherical shape, and / or the capsule or capsules each have an ellipsoidal shape.

[0145] Preferably, the capsule or capsules have a larger dimension which is between 0.5mm and 5mm, or between 1mm and 3mm.

[0146] Thus, these simple shapes and small sizes are particularly well suited to the aroma capsules to be installed in the aroma diffuser according to the invention.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] The reservoir contains at least one capsule of flavoring liquid or gel, designed to open and release the liquid or gel flavor it contains, while the reservoir and its casing (cap, etc.) are made of flexible materials. In this case, upon first use, the consumer may press on the diffuser to open the capsule, for example by bursting, tearing, or possibly breaking.

[0164] Once the capsule is opened, it releases its contents, but of course, these will be preserved in the reservoir as long as the diffuser is in closed mode.

[0165] Guiding means, such as rails in the form of circular grooves for example, can be provided between the elements to ensure rotational movements.

[0166] 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.

[0167] 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.

[0168] Throughout the rest of the text, elements such as the diffuser, the reservoir and the shutter will be presented as annular for convenience of language even though they may only be partially annular (i.e. do not make a complete turn but only part of a complete turn).

[0169] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0170] Figure 1 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention.

[0171] 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.

[0172] The aroma diffuser 2 is annular and includes an aroma reservoir 5, also annular. The annular aroma diffuser 2 and the annular aroma reservoir 5 are both 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 seen in Figure 1) and / or on the upper wall of the reservoir 5 (not shown in Figure 1). The orifices 6 of the reservoir 5 can be opened or closed by a movable shutter 7 (not shown in Figure 1).

[0173] Figure 2 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.

[0174] The beverage device includes a bottle 1 and an aroma diffuser 2.

[0175] 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 40 for a screw cap 3, and by a collar 41 located below the external thread 40 of the neck 4.

[0176] The aroma diffuser 2 includes an aroma reservoir 5 which is annular or partially annular in shape so as to be able to be placed around the neck 4 of this bottle 1, and also includes several aroma diffusion orifices 6.

[0177] The shutter 7 is movable, relative to the reservoir 5, between, on the one hand, a position of simultaneous closure of all the orifices 6, 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, allowing the diffusion of aroma out of the reservoir 5, both around the neck 4 of the bottle 1, and also towards the top of this bottle 1. Here, the shutter 7 is movable in rotation about the vertical axis Z and about the reservoir 5. The reservoir is shown with diffusion orifices 6 on its outer lateral wall 5 If. When the shutter 7 rotates around the reservoir 5, if the orifices 70 of the shutter 7 are opposite the diffusion orifices 6 of the reservoir 5, then the diffusion orifices 6 are open and can spread the aroma outwards from the reservoir 5.When the shutter 7 rotates around the reservoir 5, if the orifices 70 of the shutter 7 are not opposite the diffusion orifices 6 of the reservoir 5, then the diffusion orifices 6 are closed because they are covered by the solid wall of the shutter 7 and cannot diffuse the aroma outwards from the reservoir 5, this aroma remaining stored (in a form allowing the aroma to volatilize when the diffusion orifices are opened) inside the reservoir 5. The reservoir 5 could alternatively or cumulatively have diffusion orifices 6 on its upper face 51s. These diffusion orifices 6 would then be closed when the solid wall of an upper horizontal flap (actually perpendicular to the vertical axis Z) (not shown) of the shutter 7, parallel to this upper face 51s of the reservoir 5, covered the diffusion orifices 6 that would also be located on the upper face 51s of tank 5.These diffusion orifices 6 would then be open when the orifices 70 of this upper horizontal flap (actually perpendicular to the vertical axis Z) (not shown) of the shutter 7, parallel to this upper face 51s of the reservoir 5, would be opposite the diffusion orifices 6 located on the upper face 51s of the reservoir 5.

[0178] 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 means of 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 arranged at two levels and of annular shape, clamp the collar 41 together, thus blocking the movement of the diffuser 2 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.

[0179] 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.

[0180] In another option, the reservoir 5 and / or the diffuser 2 is partially annular in shape, making between 60% and 90% of a complete turn around their axis (as illustrated in Figure 1). Thus, a good compromise is achieved between, on the one hand, the positional stability 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 part where the missing part (the hole) of the annular shape is located, is provided 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 31.

[0181] 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.

[0182] There are at least 4, or at least 6, or at least 10 aroma diffusion orifices. Thus, regardless of the position of the fingers of the hand of the user holding bottle 1 when the user drinks the contents of bottle 1, the diffusion of aroma around the neck 4 of bottle 1, towards the nose of the user who drinks the contents of bottle 1, remains significant, regardless of the position of the user's fingers.

[0183] The 80 clips are evenly distributed around the Z-axis of the annular or partially annular shape. This positions the diffuser 2 even more stably around the neck 4 of the bottle 1.

[0184] 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.

[0185] 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 5 li of the wall 51 of the reservoir 5. This internal protrusion 80 is made of a more elastic material than the material of the wall 51 of the reservoir 5. Thus, the diffuser 2 is positioned around the neck 4 of the bottle 1 in an even more stable manner.Positioning the diffuser 2 in its clipped / locked position is facilitated by the clips 80 snapping into place on either side (along the Z-axis) of the collar 4L. Indeed, the internal protrusion 80, due to its elastic deformability, allows the diffuser 2 to engage under the collar 41 of the bottle 1 as it moves towards locking. When the diffuser 2 is pulled from its locked position to its unlocked position, it resists retraction up to a certain (reasonable) force. The clip(s) 80 are arranged 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, thus positioning 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 on the one hand and the cap 3 on the other is short, of intermediate length, or long.

[0186] In one option, the aroma is a fruity fragrance. This makes the experience of drinking water even more pleasant for the user.

[0187] 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.

[0188] 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.

[0189] 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.

[0190] Figure 3 schematically represents a side view of a beverage device comprising an aroma diffuser according to the invention, for a first type of shutter, in the position of closing the aroma diffusion orifices.

[0191] In Figure 3, 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.

[0192] The aroma diffuser 2 is annular and includes an aroma reservoir 5, also annular. The annular aroma diffuser 2 and the annular aroma reservoir 5 are both positioned around the neck 4 and 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 seen in Figure 3) and / or on the upper wall of the reservoir 5 (not shown in Figure 3). The orifices 6 of the reservoir 5 can be opened or closed by a movable shutter 7, which, in Figure 3, is in the position of closing the aroma diffusion orifices 6.The movable shutter 7 may include orifices 70 which, in Figure 3, are offset from the aroma diffusion orifices 6 of the reservoir 5, so that the shutter 7 keeps these aroma diffusion orifices 6 of the reservoir 5 closed. The movable shutter 7 will then rotate around the vertical axis Z in the direct direction of rotation to move into the position of opening the aroma diffusion orifices 6 (as shown in Figure 4). 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 the simple elasticity of the partially annular shape of the diffuser 2 and the reservoir 5, allowing the diffuser 2 and the reservoir 5 to clip around the neck 4 of the bottle 1, under the collar 41 of the neck 4 of this bottle 1, and even between the collar 41 and the conical shape 10 of the body of the bottle 1.Advantageously, the height of the diffuser 2 is substantially equal to the distance between the collar 41 and the conical shape 10 of the body of the bottle 1 so as to remain in a stable, or even immobile, position around the neck 4 of the bottle 1. The application by the user of a very limited but deliberate effort makes it possible to unblock the diffuser 2 and move it away from the neck 4 of the bottle 1.

[0193] The reservoir 5 and / or the diffuser 2 is partially annular in shape, completing between 60% and 90% of a full rotation around its axis (as illustrated in Figure 3). This achieves a good compromise between, on the one hand, the positional stability 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. This space is designed to receive the cap 3 once it has been unscrewed and removed from the neck 4 of the bottle 1, even when the cap 3 remains attached to a safety ring 30 located around the neck 4 of the bottle 1 by a relatively short link 31.

[0194] 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.

[0195] There are at least 4, or at least 6, or at least 10 aroma diffusion orifices. Thus, regardless of the position of the fingers of the hand of the user holding bottle 1 when the user drinks the contents of bottle 1, the diffusion of aroma around the neck 4 of bottle 1, towards the nose of the user who drinks the contents of bottle 1, remains significant, regardless of the position of the user's fingers.

[0196] In one option, the aroma is a fruity fragrance. This makes the experience of drinking water even more pleasant for the user.

[0197] 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.

[0198] 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.

[0199] Figure 4 schematically represents a side view of the beverage device of Figure 3 comprising an aroma diffuser according to the invention, for a first type of shutter, in the position of opening the aroma diffusion orifices.

[0200] In Figure 4, 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.

[0201] The aroma diffuser 2 is annular and includes an aroma reservoir 5, also annular. The annular aroma diffuser 2 and the annular aroma reservoir 5 are both positioned around the neck 4 and 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 seen in Figure 3) and / or on the upper wall of the reservoir 5 (not shown in Figure 3). The orifices 6 of the reservoir 5 can be opened or closed by a movable shutter 7, which, in Figure 4, is in the position of opening the aroma diffusion orifices 6.The movable shutter 7 may include orifices 70 which, in Figure 4, are superimposed on the aroma diffusion orifices 6 of the reservoir 5, so that the shutter 7 keeps these aroma diffusion orifices 6 of the reservoir 5 open. Advantageously, the orifices 70 of the shutter 7 are larger than the aroma diffusion orifices 6 of the reservoir 5 so as to completely cover and even exceed these aroma diffusion orifices 6 of the reservoir 5. The movable shutter 7 will then rotate about the vertical axis Z in the indirect direction of rotation (opposite direction of rotation to the direction of rotation of Figure 3) to move into the position of closing the aroma diffusion orifices 6 (as shown in Figure 3).

[0202] Once the movable annular shutter 7 is installed around the reservoir 5, i.e. either clipped to the outside of the reservoir 5, or fitted around the reservoir 5, this shutter 7 is movable, relative to the reservoir 5, between, on the one hand, a position of simultaneous closure of all the orifices 6, 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 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.

[0203] To obtain the position corresponding to the simultaneous closure of all orifices 6, thus preventing aroma diffusion from the reservoir 5, the movable shutter 7 is rotated around the vertical axis Z so that the orifices 70 are no longer aligned with the diffusion orifices 6 of the reservoir 5. This allows the solid wall of the movable shutter 7 to cover and thus close the diffusion orifices 6 of the reservoir 5. This design resembles a salt shaker mechanism with a rotating lid. In fact, the shutter 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 shape of the reservoir 5.

[0204] The movable shutter 7 can cover and thus close the diffusion orifices 6 of the reservoir 5, whether these are located on the side wall of the reservoir 5 or on the top wall of the reservoir 5. This is achieved simply by having a cylindrical shape with an annular face when the movable shutter rotates. In another embodiment, the movable shutter could move in translation; its shape would simply need to be adapted.

[0205] Figure 5 schematically represents a view of an example of a first type of aroma capsule implemented in an example of an aroma reservoir of an aroma diffuser according to the invention.

[0206] The flavor capsule 76 contains a liquid flavor 78 surrounded by a membrane 77 that opens when the user applies pressure to the capsule 76, for example, by squeezing it between their fingers. To facilitate this, the membrane 77 advantageously incorporates lines of weakness that tear under the applied pressure. Once the membrane 77 is open, the liquid flavor 78 can be released into the reservoir 79. The flavor capsule 76 is spherical in shape.

[0207] Figure 6 schematically represents a view of an example of a second type of aroma capsule implemented in an example of an aroma reservoir of an aroma diffuser according to the invention.

[0208] The flavor capsule 76 contains a liquid flavor 78 surrounded by a membrane 77 that opens when the user applies pressure to the capsule 76, for example, by squeezing it between their fingers. To facilitate this, the membrane 77 advantageously incorporates lines of weakness that tear under the applied pressure. Once the membrane 77 is open, the liquid flavor 78 can be released into the reservoir 79. The flavor capsule 76 is ellipsoidal in shape.

[0209] Figure 7 schematically represents a top view of an example of an aroma diffuser according to the invention, with a shutter, and with a first type of aroma reservoir, in a position of open diffusion orifices.

[0210] The aroma diffuser 2 includes a shutter 7 mounted on an aroma reservoir 5. Both the shutter 7 and the aroma reservoir 5 have a partially annular shape. The aroma reservoir 5 is essentially formed by a hollow body 100, also partially annular in shape. The hollow body 100 includes an internal volume 110 in which the aroma reservoir 79 is installed. This reservoir is formed by an absorbent material 79 comprising one or more aroma capsules 76 (such as those shown in Figures 5 or 6). The hollow body 100 includes aroma diffusion openings 6 from the internal volume 110 of the hollow body 100 to the outside of the hollow body 100, i.e., from the aroma reservoir 79 located inside the aroma reservoir 5 to the outside of the aroma reservoir 5.

[0211] The shutter 7 rotates around the Z-axis and also rotates around the aroma reservoir 5 by sliding in the hollow part 107 of the hollow body 100. The hollow part 107 of the hollow body 100 is located on the outer periphery of the hollow body 100. The user can easily rotate the shutter 7 using a gripping member 700. The shutter 7 has a gripping member 700, located in the middle of the shutter 7, on its outer face opposite its inner face in contact with the aroma reservoir 5, in the form of a protrusion, allowing the shutter 7 to be moved relative to the reservoir 5 by a rotational movement of the shutter 7 around the reservoir 5.

[0212] When the shutter 7 comes against the stop 109, the orifices 70 of the shutter 7 are opposite the orifices 6 of the hollow body 100 of the reservoir 5, these orifices 6 being then open, and the aroma can be diffused out of the reservoir 5, with the greatest gaseous diffusion rate, once the aroma capsule 76 has been opened, by pressure of the user's finger(s) on the weak area 101 which is a soft area (for example made of fabric or rubber) made in the otherwise rigid wall of the hollow body 100 (for example made of plastic).

[0213] Figure 8 schematically represents a top view of an example of an aroma diffuser according to the invention, with a shutter, and with a first type of aroma reservoir, in a position of closing the aroma diffusion orifices.

[0214] When the obturator 7 comes against the stop 108, the orifices 70 of the obturator 7 are no longer opposite the orifices 6 of the hollow body 100 of the reservoir 5, these orifices 6 being then closed, and the aroma can no longer be diffused to the outside of the reservoir 5, therefore the gaseous diffusion rate is zero or practically zero (except for gas leaks), even when the aroma capsule 76 has been opened, by pressure of the user's finger(s) on the area of ​​weakness 101 which is a soft area (for example made of fabric or rubber) made in the otherwise rigid wall of the hollow body 100 (for example made of plastic).

[0215] When the obturator 7 is located between the stop 108 and the stop 109, the orifices 70 of the obturator 7 are partially opposite the orifices 6 of the hollow body 100 of the reservoir 5, these orifices 6 being then partially open, and the aroma can be diffused out of the reservoir 5, but at a gaseous diffusion rate which is less than the maximum gaseous diffusion rate.

[0216] Figure 9 schematically represents a top view of an example of an aroma diffuser according to the invention, with a shutter, and with a second type of aroma reservoir, in a position of open diffusion orifices.

[0217] The usable volume, i.e., the internal volumes 111 and 112, of the aroma diffuser shown in Figures 9 to 12, is significantly smaller than the usable volume, i.e., the internal volume 110, of the diffuser shown in Figures 7 and 8. However, the aroma reservoirs 79 can be exchanged by the user, who reuses the rest of the diffuser 2 and only replaces the reservoirs 79, which become the consumable element. The hollow body 100 and the shutter 7 are the potentially reusable elements. In the aroma diffuser shown in Figures 9 to 12, the usable volume is more limited, but some elements are reusable.

[0218] The aroma diffuser 2 includes a shutter 7 mounted on an aroma reservoir 5. Both the shutter 7 and the aroma reservoir 5 have a partially annular shape. The aroma reservoir 5 is essentially formed by a hollow body 100, also partially annular in shape. The hollow body 100 comprises two small internal volumes 111 and 112, in which are respectively installed two small aroma reservoirs 79, each formed of an absorbent material 79 comprising and surrounding an aroma capsule 76 (such as those shown in Figures 5 or 6). The hollow body 100 includes two aroma diffusion orifices 6, respectively, from the internal volumes 111 and 112 of the hollow body 100 to the outside of the hollow body 100, that is, from these aroma reservoirs 79 located inside the aroma reservoir 5 to the outside of the aroma reservoir 5.

[0219] The shutter 7 rotates around the Z-axis and also rotates around the aroma reservoir 5 by sliding in the hollow part 107 of the hollow body 100. The user can easily rotate the shutter 7 using the rough outer gripping surfaces 701. The shutter 7 has several rough outer gripping surfaces 701 on its outer face opposite its inner face in contact with the aroma reservoir 5, allowing the shutter 7 to be moved relative to the reservoir 5 by a rotational movement of the shutter 7 around the reservoir 5.

[0220] When the shutter 7 comes against the stop 109, the orifices 70 of the shutter 7 are opposite the orifices 6 of the hollow body 100 of the reservoir 5, these orifices 6 being then open, and the aroma can be diffused out of the reservoir 5, with the greatest gaseous diffusion rate, once the aroma capsule 76 has been opened, by pressure of the shutter 7 on the capsules 76 to open them during the rotation of this shutter 7.

[0221] Figure 10 schematically represents a top view of an example of an aroma diffuser according to the invention, with a shutter, and with a second type of aroma reservoir, in a position of closing the aroma diffusion orifices.

[0222] When the obturator 7 comes against the stop 108, the orifices 70 of the obturator 7 are no longer opposite the orifices 6 of the hollow body 100 of the reservoir 5, these orifices 6 being then closed, and the aroma can no longer be diffused to the outside of the reservoir 5, so the gaseous diffusion rate is zero or practically zero (except for gas leaks), even when the aroma capsule 76 has been opened.

[0223] The two capsules 76 will have been opened by the shutter 7 during its rotation, from the stop 109 towards the stop 108, because this shutter 7 will press against the parts of the capsules 76 which protrude out of the orifices 6 (while being covered by the absorbent material 79), causing these capsules 76 to burst or tear under pressure, causing their liquid aroma 78 to spread into the absorbent material 79 which surrounds each capsule 76.

[0224] When the obturator 7 is located between the stop 108 and the stop 109, the orifices 70 of the obturator 7 are partially opposite the orifices 6 of the hollow body 100 of the reservoir 5, these orifices 6 being then partially open, and the aroma can be diffused out of the reservoir 5, but at a gaseous diffusion rate which is less than the maximum gaseous diffusion rate.

[0225] In an alternative embodiment, the aroma capsules 76 are located at the level of all or part of the orifices 6 but do not protrude out of the orifices 6 towards the outside of the reservoir 5. The obturator 7 of the reservoir 5 includes at least one protrusion directed towards the inside of the reservoir 5. The obturator 7 of the reservoir 5 is arranged so as to open the aroma capsules 76 by the movement of this obturator 7, when all or part of the orifices 6 are simultaneously closed, the protrusion of the obturator 7 then opening the aroma capsules 76 by passing over them.

[0226] Figure 11 schematically represents an exploded view of an example of an aroma diffuser according to the invention, with a shutter, and with a second type of aroma reservoir.

[0227] The two aroma reserves 79, that is to say the absorbent materials 79 surrounding aroma capsules 76, will be placed respectively in the internal volumes (111 hidden in Figure 11) and 112 (visible in Figure 11).

[0228] The shutter 7 will be clipped into the hollow part 107 of the hollow body 100, so that it can then rotate around this hollow body 100, by sliding in the hollow part 107 of this hollow body 100.

[0229] Figure 12 schematically represents a perspective view of an example of an aroma diffuser according to the invention, with a shutter, and with a second type of aroma reservoir, in a position of open diffusion orifices.

[0230] The user rotates the shutter 7 around the hollow body 100, by pressing with his or her finger(s) on the rough outer surface 701 of the shutter 7, and can then at will: either close the reservoir 5, by offsetting the orifices 70 of the shutter 7 relative to the diffusion orifices 6 of the hollow body 100 of the reservoir 5, or open the reservoir 5, by superimposing the orifices 70 of the shutter 7 relative to the diffusion orifices 6 of the hollow body 100 of the reservoir 5, or even partially open the reservoir 5, by partially superimposing the orifices 70 of the shutter 7 relative to the diffusion orifices 6 of the hollow body 100 of the reservoir 5.
