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 excellent for health, but many users find it too bland, whether still or sparkling. Fruit juices might seem, at first glance, to offer 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.

[0005] 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.

[0006] 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.

[0007] 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.

[0008] According to prior art, for example described in US patent 5635229 ([Fig.5]), a water bottle associated with a localized aroma diffuser is known. at the level 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.

[0009] 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

[0010] The invention proposes an alternative approach to solving this problem. The invention provides an aroma diffuser whose design, shape, and structure make it directly usable with a commercially available bottle of mineral water, without any adaptation of the bottle's shape or structure. The aroma is diffused when the user drinks the water from the bottle. Thus, the aroma diffuser offers users simplicity and flexibility in its use, also allowing them to save money.

[0011] 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.

[0012] 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, - adhering to a sustainable and responsible development objective: that of achieving a simple manufacturing process for the invented diffuser, requiring no or virtually no change to the manufacturing process of the containers with which it will cooperate, particularly water bottles, which will allow for standardization of The use of such a diffuser, i.e. facilitated adoption by consumers, relevant industries, and even regulators who see it as a dual issue of public health and avoiding the proliferation of capsules with proprietary designs, will thus confirm the desired objective of sustainable and responsible development.

[0013] 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 surrounded by a thread for a screw cap and by a collar located below the thread of the neck, comprising: • an aroma reservoir, • such that this aroma reservoir and / or diffuser is or are partially annular in shape, forming between 60% and 90% of a full rotation, so that it can be clipped around the neck of this bottle, under the collar of the neck of this bottle, • and comprising several aroma diffusion openings, • a tank shutter, • mobile, relative to the reservoir, between: • a position where all these orifices are simultaneously closed, preventing aroma from escaping the reservoir, • and a position of simultaneous opening of all these orifices allowing the diffusion of aroma out of the reservoir, around the neck of this bottle, towards the top of this bottle.

[0014] The aroma reservoir is partially annular in shape, forming between 60% and 90% of a full circumference, 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 one or more compartments in which one or more aromas are stored. This 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 partially annular in shape, forming between 60% and 90% of a full circumference.Either the chamber(s) or the compartment(s) are partially annular in shape, forming less than 60% and 90% of a full rotation, but then its support is also partially annular in shape, 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 cross-section of the reservoir compartment(s). The diffuser. as a whole is advantageously 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.

[0015] 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.

[0016] 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.

[0017] It is this partially annular shape, making more than half a turn but not a full turn, of the aroma reservoir which will allow to clip very simply and very easily this aroma reservoir around the neck of the bottle, just under the collar of the neck of the bottle, the aroma reservoir being then held by the domed part of the body of the bottle flaring under the collar of the neck of the bottle.

[0018] 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 the shape of a cone before reaching its maximum corresponding to the cylindrical part with a constant or practically constant circular cross-section of the bottle.

[0019] By clipping around the neck of the bottle, the internal part of the annular shape of the reservoir is advantageously at least partially in contact with the neck of the bottle itself, in the part where its external diameter is minimal.

[0020] The aroma reservoir can in particular be clipped 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 enclose the neck of the bottle.

[0021] This partially annular shape allows, for a given shape and size of tank, in particular to adapt to a certain range of external diameters of bottle neck, while maintaining a good compromise between the following two properties: • The aroma reservoir can be easily and simply clipped 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.

[0022] The range of outside diameters may cover a few millimeters, for example at least 4 mm or at least 6 mm (especially when the reservoir has an internal layer or inward protrusions, as envisaged in option(s) in [Fig. 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 reservoir is between 20 mm and 30 mm. Preferably, the internal diameter of the bottle neck is also between 20 mm and 30 mm.

[0023] This partially annular shape is advantageously a torus shape whose section is, for example, circular or rectangular.

[0024] 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.

[0025] The shape and size of both the aroma reservoir and the aroma diffuser can thus be respectively simple and reduced.

[0026] 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 liters, including: • a collar, • surrounded by a thread for a screw cap, • and by a collar, located under the threads of the neck, • an aroma diffuser including: • an aroma reservoir, • such that this aroma reservoir and / or diffuser is or are partially annular in shape, forming between 60% and 90% of a full rotation, so that it can be clipped around the neck of this bottle, under the collar of the neck of this bottle, • and comprising several aroma diffusion openings, • a tank shutter, • mobile, relative to the reservoir, between: • a position where all these orifices are simultaneously closed, preventing aroma from escaping the reservoir, • and a position of simultaneous opening of all these orifices allowing the diffusion of aroma out of the reservoir, around the neck of this bottle, towards the top of this bottle.

[0027] 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.

[0028] Preferably, the reservoir and / or diffuser is or are partially annular in shape, making between 65% and 85% of a complete turn.

[0029] This reduced angular coverage range of the partially annular shape allows, for a given shape and size of a single tank, in particular to adapt to a certain range of external bottle neck diameters, while maintaining a better compromise between the following two properties: • The aroma reservoir can be easily and simply clipped 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.

[0030] Preferably, the reservoir and / or diffuser is or are of partially annular shape, making between 70% and 80% of a complete turn.

[0031] This even smaller range of angular coverage of the partially annular shape allows, for a given shape and size of a single tank, in particular to adapt to a certain range of external bottle neck diameters, while maintaining an even better compromise between the following two properties: • The aroma reservoir can be easily and simply clipped around the neck of the bottle, • the aroma reservoir remains around the neck of the bottle without falling out, 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.

[0032] Preferably, the aroma reservoir is partially annular in shape and made of a material or several 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.

[0033] Thus, the clipping is partially simple and easy to do.

[0034] 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.

[0035] Thus, the clipping is partially simple and easy to do.

[0036] Preferably, the wall of the aroma reservoir is made of plastic.

[0037] Thus, the reservoir is strong and simple to manufacture, and its partially annular shape makes it sufficiently elastic overall to easily clip around the neck of the bottle, even though the plastic remains inherently quite rigid, while still remaining securely clipped around the neck of the bottle. This material is particularly well suited when the partially annular shape is between 60% and 75% of a full circumference.

[0038] Preferably, the wall of the aroma reservoir is made of rubber.

[0039] Thus, the reservoir is particularly flexible, allowing it to easily clip around the neck of the bottle. This material is particularly well suited when the partially annular shape is between 75% and 90% of a full turn.

[0040] Preferably, the aroma reservoir comprises an aroma chamber including several aroma diffusion orifices or two aroma chambers each including several aroma diffusion orifices.

[0041] Thus, the chamber structure is simpler and more robust, and this chamber is easier to fill with aroma during the manufacture of the diffuser, but the reservoir has a certain volume. This remains true for two chambers, but to a slightly lesser extent.

[0042] In the case of two chambers, it is still possible to mix two different aromas during aroma diffusion.

[0043] Preferably, the aroma reservoir comprises several aroma compartments, each comprising a single aroma diffusion orifice.

[0044] 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.

[0045] Preferably, each aroma compartment is an aroma niche whose largest dimension is between 100% and 140% of the largest dimension of its aroma diffusion orifice, or whose largest dimension is between 105% and 120% of the largest dimension of its aroma diffusion orifice.

[0046] Thus, the structure of the compartments is simpler, they are practically compartments simply open on one side.

[0047] 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.

[0048] Thus, the movement of the shutter can easily correspond to a rotational kinematic.

[0049] 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 which is less than that of the tank.

[0050] Thus, the movement of the shutter can easily correspond to a rotational kinematic.

[0051] 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 relative to the aroma diffusion orifices and the open position where its openings are opposite the aroma diffusion orifices.

[0052] Thus, this rotational kinematics is more fluid to realize than a translational kinematics would be.

[0053] Preferably, the tank closure is movable, relative to the tank, between the closed position and the open position, by rotation around the tank, this rotation taking place around an axis of rotation which on the one hand passes through the center of the annular shape of the tank and on the other hand is orthogonal to the average plane of the annular shape of the tank.

[0054] Thus, the movement of the shutter corresponds to a sliding kinematic of an outer (partial) ring around an inner (partial) ring. This kinematic is very smooth.

[0055] Preferably, the shutter is made of plastic.

[0056] Thus, the sliding is more stable.

[0057] Preferably, the reservoir has a torus shape, and the reservoir's obturator is movable, relative to the reservoir, between the closed position and the open position opening, by rotation around the axis of the torus forming the reservoir, that is to say around the curved line which is at the center of the section of the torus along the torus.

[0058] Thus, the movement of the shutter corresponds to a rotational kinematic of a sleeve around an arm, which kinematic is a little less fluid, but the closing and opening positions will be more stable, than for the previous sliding kinematic of an outer (partial) ring around an inner (partial) ring.

[0059] Preferably, the shutter is made of textile or fabric or rubber.

[0060] Thus, the rotation is made smoother.

[0061] Preferably, the aroma reservoir includes one or more protrusions that are formed or fixed on the outer wall of the reservoir which are located inside the partially annular shape of the reservoir, and / or which are oriented towards the center of the partially annular shape of the reservoir.

[0062] 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.

[0063] Preferably, the aroma reservoir comprises several protrusions which are regularly distributed around the partially annular shape of the reservoir, preferably between 2 and 5 protrusions.

[0064] 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.

[0065] Preferably, the protuberance(s) are made of textile or fabric or rubber.

[0066] Thus, the higher friction of these materials makes it possible to further stabilize the angular position of the reservoir (and also of the diffuser) around the neck of the bottle.

[0067] Preferably, the aroma reservoir contains an aroma in liquid or solid form. This allows the aroma to be stored in a simpler and more concentrated form.

[0068] Preferably, the aroma reservoir includes an aroma carrier and the aroma is absorbed by or contained within this carrier.

[0069] Preferably, the aroma carrier is in the form of foam or sponge.

[0070] Preferably, the aroma carrier is formed by an absorbent material, which is suitable for contain this aroma in liquid or solid form, which allows the aroma it has absorbed to diffuse in gaseous form.

[0071] Preferably, the aroma carrier is essentially formed: • either by silicone, • either by porous ceramic, • either by a thermoplastic elastomer (TPE), • either by polyurethane foam (PU Foam).

[0072] Preferably, the aroma support is chargeable or rechargeable by immersion in an aroma solution, this aroma solution being preferably heated.

[0073] Thus, filling the aroma reservoir with its aroma is very efficient, even if the charging time can be relatively long. This charging time is shortened by heating the aroma solution.

[0074] Preferably, the aroma support is essentially formed: either by silicone, or by a porous ceramic, or by a thermoplastic elastomer (TPE), or by a polyurethane foam (PU Foam).

[0075] Thus, these materials achieve a good or relatively good compromise between all the required properties, and in particular the high rate of gas diffusion, good water impermeability, good flexibility to facilitate installation, and good recyclability (since the diffuser is a disposable element, with the standard bottle).

[0076] Silicone and porous ceramic will rather be used with an aroma reservoir which is in one part containing the aroma, the silicone and porous ceramic forming the part having the function of being able to contain the aroma.

[0077] Thermoplastic elastomer (TPE) and polyurethane foam (PU Foam) can be used with an aroma reservoir that contains the aroma, the thermoplastic elastomer (TPE) and the polyurethane foam (PU Foam) forming the part that contains the aroma.

[0078] Preferably, the ends of the annular shape of the aroma reservoir are respectively extended, respecting said annular shape, by clips with a reduced cross-section compared to the cross-section of the reservoir.

[0079] Thus, these clips extending the ends of the annular shape of the reservoir along this annular shape allow for a better grip on the neck of the bottle while making it very easy to clip around the neck of the bottle.

[0080] Preferably, the aroma diffusion orifices are regularly distributed around the axis of the annular or partially annular shape.

[0081] 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.

[0082] Preferably, there are at least 4 or at least 6 aroma diffusion orifices.

[0083] Thus, regardless of the position of the fingers of the user's hand holding the bottle when the user drinks the contents of the bottle, the aroma diffusion around the neck of the bottle, towards the nose of the user who drinks the contents of the bottle, remains important.

[0084] Preferably, the tank's obturator is movable relative to the tank by rotation around an axis of rotation parallel to the axis of the annular or partially annular shape.

[0085] Thus, a simple rotating gesture by the user allows the aroma to be released outside the reservoir containing the aroma of the diffuser.

[0086] In addition, the opening and closing positions of the shutter are even more stable.

[0087] Preferably, the aroma diffuser is a replaceable consumable.

[0088] Thus, the simple shape and small size of the entire diffuser allows it to to create a replaceable consumable, while costing little to the user and remaining quite ecological, because this diffuser with its simple shape and small size is easily recyclable.

[0089] 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.

[0090] The shape and size of both the aroma reservoir and the aroma diffuser can thus be respectively simple and reduced.

[0091] 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.

[0092] The shape and size of both the aroma reservoir and the aroma diffuser can thus be respectively very simple and very small.

[0093] Preferably, the height of the diffuser and / or the height of the reservoir is or are substantially equal to the distance between the neck flange and the conical shape of the bottle body. This allows the diffuser to be positioned more stably, or even immobile, around the neck of the bottle. The height of the diffuser and the height of the reservoir are measured along the same vertical axis Z as the bottle itself.

[0094] Preferably, the aroma is a fruity fragrance.

[0095] Thus, the sensation of drinking water becomes even more pleasant for the user.

[0096] Preferably, the aroma includes a component which has an effect of: either appetite suppression, taste desensitization, or taste re-education.

[0097] Thus, the simple act of drinking water can improve or even restore other sensations useful to the user. 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.

[0098] 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.

[0099] Preferably, at least the reservoir, and preferably also the diffuser, is made or are made of natural cellulose.

[0100] Thus, the reservoir and / or diffuser are cheaper and more environmentally friendly, because they are more easily recyclable.

[0101] Taste receptors can only register five distinct tastes, whereas there are hundreds of types of olfactory receptors allowing 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 drawback.

[0102] 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.

[0103] The disposable water bottle is preferably recyclable or at least partly recyclable.

[0104] The disposable water bottle is opposed, for example, to a constantly reusable water bottle.

[0105] Advantageously, the aroma may emanate from a substance contained therein, 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 may not only improve the diffusion of an aroma, but may also improve, in particular, its preservation and / or aeration.

[0115] 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.

[0116] Similarly, the term "internal surface" refers to the surface of a part directed towards the inside of the bottle, and similarly, the term "external surface" refers to the surface of a part directed towards the outside of the bottle, that is, in a direction substantially opposite to the direction of the inside of the bottle. 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.

[0117] 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.

[0118] Guiding means, such as rails in the form of circular grooves for example, can be provided between the elements to ensure rotational movements.

[0119] 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.

[0120] 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.

[0121] Throughout the rest of this text, elements such as the diffuser, the reservoir, and the shutter will be referred to as annular for the sake of simplicity, even though they are only partially annular (i.e., they do not complete a full rotation but only part of one). If an element is required to complete a full rotation to be annular, it will be referred to as completely annular.

[0122] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

[0123] Fig. 1 schematically represents a profile 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.

[0124] In [Fig. 1], a cylindrical water bottle 1 terminates at its upper end, along the Z-axis, in a neck 4 of the bottle 1, 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 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.

[0125] The aroma diffuser 2 is annular and includes an aroma reservoir 5 that is also annular. The annular aroma diffuser 2 and the annular aroma reservoir 5 are all positioned around the neck 4 and partially encircle the neck 4. The reservoir 5 includes aroma diffusion orifices 6 for diffusing the aroma contained in the reservoir 5 towards the outside of the reservoir 5 and therefore towards the outside of the diffuser 2. The orifices 6 are preferably located on the outer side wall of the reservoir 5 (as shown in [Fig. 1]) and / or on the upper wall of the reservoir 5 (not shown in [Fig. 1]). The orifices 6 of the reservoir 5 can be opened or closed by a movable shutter 7 which, in [Fig. 1], is in the position of closing the aroma diffusion orifices 6. The movable shutter 7 may include orifices 70 which, in [Fig. 1], are offset relative to 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 then rotates around the vertical axis Z in the direction of direct rotation to move into the position of opening the aroma diffusion orifices 6 (as shown in [Fig. 2]).

[0126] 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 force makes it possible to unblock the diffuser 2 and move it away from the neck 4 of the bottle 1.

[0127] 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 [Fig. 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.

[0128] 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 time.

[0129] 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 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 who drinks the contents of the bottle 1, remains significant, regardless of the position of the user's fingers.

[0130] In one option, the aroma is a fruity fragrance. Thus, the sensation of drinking water becomes even more pleasant for the user.

[0131] 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.

[0132] 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.

[0133] Fig. 2 schematically represents a profile view of the beverage device of Fig. 1 comprising an aroma diffuser according to the invention, for a first type of shutter, in the position of opening the aroma diffusion orifices.

[0134] In [Fig. 2], a cylindrical water bottle 1 terminates at its upper end, along the Z-axis, in a neck 4 of the bottle 1, 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 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.

[0135] The aroma diffuser 2 is annular and includes an aroma reservoir 5 that is 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 [Fig. 1]) and / or on the upper wall of the reservoir 5 (not shown in [Fig. 1]). The orifices 6 of the reservoir 5 can be opened or closed by a movable shutter 7, which, in [Fig. 2], is in the position of opening the aroma diffusion orifices 6. The movable shutter 7 may include orifices 70 which, on the [Fig.2], 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 [Fig. 1]) to move into the position of closing the aroma diffusion orifices 6 (as shown in [Fig. 1]).

[0136] Once the movable annular shutter 7 is installed around the reservoir 5, i.e. clipped to the outside of the reservoir 5 in Figures 1 to 4, but fitted around the reservoir 5 in Figures 6 and 7, 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.

[0137] To obtain the position also shown in [Fig. 1], corresponding to a position where all the orifices 6 are simultaneously closed, thus preventing aroma diffusion from the reservoir 5, it is sufficient to rotate the movable shutter 7 around the vertical axis Z so that the orifices 70 are no longer opposite the diffusion orifices 6 of the reservoir 5, and so that the solid wall of the movable shutter 7 covers and thus closes the diffusion orifices 6 of the reservoir 5. This embodiment resembles a salt shaker-type 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.

[0138] 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. For this to be possible, the movable shutter simply needs to have 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.

[0139] Fig. 3 schematically represents a top view of a first type of reservoir associated with a first type of shutter of an aroma diffuser according to the invention, in the position of opening the aroma diffusion orifices.

[0140] The movable shutter 7 rotates around the reservoir 5 by rotating about the vertical axis Z in the direct direction (direction of arrow Fl), which is the axis of symmetry of revolution of the bottle 1, to move from the open position of the orifices 6 ([Fig. 3]) of the reservoir 5 to the closed position of the orifices 6 of the reservoir 5 ([Fig. 4]). In [Fig. 3], the orifices 70 of the movable shutter 7 are aligned with the aroma diffusion orifices 6 of the reservoir 5. Thus, the aroma can diffuse from the reservoir 5 to the outside by passing through the orifices 6 of the reservoir 5 and the orifices 70 of the movable shutter 7.

[0141] Inside the reservoir 5 is the aroma preferably in liquid or solid form, and advantageously integrated into a support such as foam or silicone or ceramic, for example.

[0142] In one option, on the innermost outer face of the reservoir 5, i.e., at the inner diameter of the annular shape of the reservoir 5, several protrusions, advantageously in the form of pads, regularly distributed around the vertical axis Z and facing inwards towards the annular shape of the reservoir 5, may be arranged to act as a buffer between the reservoir 5 and the neck 4 of the bottle 1 when the reservoir 5 is clipped around the neck 4 of the bottle 1. These protrusions or pads are preferably made of a softer and / or more elastic material, such as textile, fabric, or rubber, than the wall of the reservoir 5, which may, for example, be made of silicone, plastic, or ceramic, etc. Preferably, there are at least three, or even at least five, pads. These pads advantageously have an additional thickness of between 1 and 3 mm, for example, 2 mm.

[0143] In another option, on the outer face of the reservoir 5 that is innermost to the reservoir 5, i.e., at the level of the inner diameter of the annular shape of the reservoir 5, an additional inner layer arranged around the vertical axis Z can be positioned to act as a buffer between the reservoir 5 and the neck 4 of the bottle 1 when this reservoir 5 is clipped around the neck 4 of the bottle 1. This inner layer is preferably made of a softer and / or more elastic material, such as textile, fabric, or rubber, than the wall of the reservoir 5, which can by for example, it can be made of silicone, plastic, or ceramic, etc... This inner layer has an advantageous extra thickness of between 1 and 3mm, for example 2mm.

[0144] Fig. 4 schematically represents a top view of the first type of reservoir associated with the first type of shutter of an aroma diffuser according to the invention as in Fig. 3, but in the position of closing the aroma diffusion orifices.

[0145] The movable obturator 7 rotates around the reservoir 5 by rotating around the vertical axis Z in the indirect direction (direction of arrow F2, opposite to the direction of arrow Fl in [Fig.3]) which is the axis of revolution symmetry of the bottle 1, to move from the position of closing the orifices 6 ([Fig.4]) of the reservoir 5 to the position of opening the orifices 6 of the reservoir 5 ([Fig.3]). In [Fig.4], the orifices 70 of the movable shutter 7 are offset from the aroma diffusion orifices 6 of the reservoir 5. Thus, the aroma cannot diffuse from the reservoir 5 to the outside, because the orifices 6 of the reservoir 5 are blocked by the solid wall of the movable shutter 7, since the orifices 70 of the movable shutter 7 are not opposite the orifices 6 of the reservoir 5.

[0146] Fig. 5 schematically represents a perspective view of the first type of reservoir of an aroma diffuser according to the invention.

[0147] The reservoir 5 includes aroma diffusion orifices 6 on its outer wall. The cross-section of the annular shape of the reservoir 5 is rectangular. Thus, the movable shutter 7 slides more easily around the reservoir 5.

[0148] Fig. 6 schematically represents a top view of a second type of reservoir associated with a second type of shutter of an aroma diffuser according to the invention, in the position of opening the aroma diffusion orifices.

[0149] The movable obturator 7 slides around the circular axis AT or the circular line AT of the reservoir 5, as a sleeve or a sleeve can rotate around an arm, following the rotation along the arrows F3, to move from the position of closing the orifices 6 ([Fig.7]) of the reservoir 5 to the position of opening the orifices 6 of the reservoir 5 ([Fig.6]).

[0150] In [Fig.6], the orifices 70 of the movable shutter 7 are opposite the aroma diffusion orifices 6 of the reservoir 5. Thus, the aroma can diffuse from the reservoir 5 to the outside by passing through the orifices 6 of the reservoir 5 and the orifices 70 of the movable shutter 7.

[0151] Inside the reservoir 5 is the aroma preferably in liquid or solid form, and advantageously integrated into a support such as foam or silicone or ceramic, for example.

[0152] Figure 7 schematically represents a top view of the second type of reservoir associated with the second type of shutter of an aroma diffuser according to the invention as in [Fig.6], but in the closed position of the aroma diffusion orifices.

[0153] The movable obturator 7 slides around the circular axis AT or the circular line AT of the reservoir 5, as a sleeve or a sleeve can rotate around an arm, following the rotation along the arrows F4, in a direction opposite to that of the arrows F3 (of the [Fig.6]), to move from the opening position of the orifices 6 ([Fig.6]) of the reservoir 5 to the closing position of the orifices 6 of the reservoir 5 ([Fig.7]).

[0154] In [Fig.7], the orifices 70 of the movable shutter 7 are offset from the aroma diffusion orifices 6 of the reservoir 5. Thus, the aroma cannot diffuse from the reservoir 5 to the outside, because the orifices 6 of the reservoir 5 are blocked by the solid wall of the movable shutter 7, since the orifices 70 of the movable shutter 7 are not opposite the orifices 6 of the reservoir 5.

[0155] In the embodiment shown in Figures 6 and 7, the orifices 70 of the movable obturator 7 move radially away from the orifices 6 of the reservoir 5 by moving outwards from the annular shape of the reservoir 5, when passing from the open position of the orifices 6 ([Fig.6]) of the reservoir 5 to the closed position of the orifices 6 of the reservoir 5 ([Fig.7]).

[0156] In an alternative embodiment to that shown in Figures 6 and 7, the orifices 70 of the movable obturator 7 can instead move away radially from the orifices 6 of the reservoir 5 by moving towards the inside of the annular shape of the reservoir 5, when passing from the opening position of the orifices 6 ([Fig.6]) of the reservoir 5 to the closing position of the orifices 6 of the reservoir 5 ([Fig.7]).

[0157] Fig. 8 schematically represents a perspective view of the second type of reservoir of an aroma diffuser according to the invention.

[0158] The reservoir 5 includes aroma diffusion orifices 6 on its upper part. The cross-section of the annular shape of the reservoir 5 is circular. Thus, the movable shutter 7, which is flexible and deformable because it is made, for example, of textile, fabric, or rubber, slides more easily around the circular axis AT of the torus formed by the reservoir 5.
