Description

[0001] Drinking device for retronasal drinking

[0002] The present invention relates to a drinking device for retronasal drinking.

[0003] The principle of retronasal drinking is explained below.

[0004] In times of growing interest in conscious and healthy eating, as well as for fitness reasons, the beverage industry offers a wide range of reduced-calorie or calorie-free drinks. Many customers want low-calorie or calorie-free beverages but don't want to compromise on taste. To meet these demands, the industry offers beverages with reduced sugar or sweetened with sugar substitutes or sweeteners. However, these substances can have other health or taste disadvantages.

[0005] As explained in the introduction to EP 3 944 792 Al, water is therefore frequently flavored with fruit. However, such flavored beverages may contain undesirable substances (such as the aforementioned sweeteners or colorings) and possibly small amounts of sugar.

[0006] EP 3 944 792 Al states the following: “Since the olfactory sensory impression constitutes an essential part of the gustatory perception when consuming food and beverages, existing drinking systems attempt to influence the odor perceived while drinking. Aroma elements are proposed for this purpose, which can be attached to a drinking vessel near the drinking opening so that the aroma element is in close proximity to the user's nose, who breathes through their nose while drinking and thus inhales the scent. WO 2019 / 016096 Al discloses a drinking device for the retronasal absorption of an aroma substance with an air-permeable aroma container that supplies aromatized air to a transport channel for drinking liquid. In this way, the aroma substance is absorbed retronasally.”The flavoring substance enters the user's mouth along with the drinking liquid and then travels retronasally through the pharynx to the olfactory mucosa, where it is detected by the receptors located there and perceived by the user. This takes advantage of the close connection between the senses of smell and taste. The user therefore gets the impression of tasting the flavor, even though they are actually only smelling it retronasally.

[0007] Drinking bottles for so-called retronasal drinking are known from the prior art, for example from EP 3 944 792 Al. However, these drinking bottles are often complex to handle. Furthermore, such bottles lack the flexibility to utilize the retronasal drinking effect independently of a specific drinking container, such as an ordinary drinking glass or bottle.

[0008] The present invention is therefore based on the objective of providing a drinking device which enables retronasal drinking to be carried out more flexibly than with devices known from the prior art.

[0009] This problem is solved with a drinking device according to claim 1.

[0010] The present invention relates to a drinking device for retronasal drinking, comprising a drinking liquid transport channel extending from a drinking liquid inlet opening to a drinking liquid outlet opening, an aroma channel extending from an aroma channel inlet opening to an aroma channel outlet opening, an aroma container with an aroma substance, wherein the aroma container has an air inlet opening and an aroma outlet opening, the aroma outlet opening being in flow communication with the aroma channel inlet opening, wherein, when drinking, in particular by applying a suction force at the drinking liquid outlet opening, drinking liquid can be conveyed through the drinking liquid transport channel, namely such that the drinking liquid enters the drinking liquid transport channel through the drinking liquid inlet opening.the drinking liquid transport channel flows through and exits the drinking liquid transport channel through the drinking liquid outlet opening, and wherein, when drinking, in particular by applying a suction force at the aroma channel outlet opening, air enriched with the flavoring substance can be conveyed through the aroma container and then through the aroma channel to the aroma channel outlet opening, namely in such a way that air enters the aroma container through the air inlet opening, that the air in the aroma container is enriched with the flavoring substance, and then exits the aroma container through the aroma outlet opening in the form of air enriched with the flavoring substance, enters the aroma channel through the aroma channel inlet opening and exits the aroma channel outlet opening.

[0011] When drinking, the liquid exits through the liquid outlet and flows into the mouth of the person drinking (the user of the drinking device). Simultaneously, air enriched with the flavoring agent flows into the mouth from the flavor channel outlet. As a result, the person drinking perceives the liquid with the taste of the flavoring agent, even though the liquid itself is not flavored. This is known as retronasal perception.

[0012] The drinking device is preferably designed in the manner or principle of a drinking straw, which can be used regardless of the shape, size, or type of drinking liquid reservoir or container. This means that drinking liquid can be drawn from any drinking liquid reservoir or container. For example, the drinking device can be used to drink from a container such as a glass, bottle, cup, mug, pot, or the like, provided it contains drinking liquid. It can also be used to drink from a drinking liquid reservoir such as a river, lake, body of water, or the like.The drinking device is positioned so that the drinking liquid inlet is in contact with the liquid in the drinking liquid reservoir or container, for example, by being immersed in it. This makes the drinking device flexible and usable regardless of the shape and size of the drinking liquid reservoir or container.

[0013] The aroma container can be designed to be replaceable, allowing the user to exchange it, for example, for refilling with flavoring or for replacement. The aroma container can be refillable with flavoring, but it can also be a single-use or reusable container (e.g., a disposable item). When drinking, the liquid outlet and the aroma channel outlet can be positioned in the user's mouth, allowing the user to apply suction to both openings. This allows flavored air and liquid to flow into the user's mouth simultaneously. Alternatively, the user can apply suction to a mouthpiece that incorporates or is fluidically connected to both the liquid outlet and the aroma channel outlet.

[0014] The drinking liquid transport channel as well as the aroma channel can have any cross-section, for example a circular, oval, or polygonal cross-section.

[0015] Further embodiments of the invention are specified in the dependent claims, these embodiments as well as further embodiments of the invention are described below.

[0016] According to one embodiment, a drinking device according to the invention may be provided in that the drinking liquid transport channel has a first transport channel section which faces the drinking liquid inlet opening, and that the drinking liquid transport channel has a second transport channel section which faces the drinking liquid outlet opening.

[0017] In one embodiment of a drinking device according to the invention, the first transport channel section and the second transport channel section can be arranged at an angle to each other, in particular at an acute, right, or obtuse angle. Providing an obtuse angle facilitates the handling of the drinking device and intensifies the taste experience due to optimized flow conditions.

[0018] In one embodiment of a drinking device according to the invention, a connecting channel section, preferably curved, can be arranged between the first transport channel section and the second transport channel section. The first transport channel section and the second transport channel section can have the same or different inner diameters and cross-sections. The inner diameter of the connecting channel section can be the same as, or different from, the inner diameter of the first transport channel section or the second transport channel section. The same applies to the cross-sectional shape.

[0019] In one embodiment of a drinking device according to the invention, the aroma channel can run at least partially parallel to the second transport channel section. This simplifies the manufacture and handling of the drinking device. Furthermore, it ensures a uniform flow of the drinking liquid and the air enriched with the aroma substance into the user's mouth.

[0020] In one embodiment of a drinking device according to the invention, the drinking liquid outlet and the aroma channel outlet can be arranged at an angle to each other. This leads to improved mixing between the drinking liquid and the aroma-enriched air in the user's mouth. It also improves the distribution of the aroma-enriched air towards the relevant receptors in the user's mouth as it enters. Furthermore, this reduces the likelihood of drinking liquid entering the aroma transport channel during drinking.

[0021] In one embodiment of a drinking device according to the invention, the opening plane of the drinking liquid outlet and the opening plane of the aroma channel outlet can be arranged at an angle to each other. This leads to improved mixing between the drinking liquid and the aroma-enriched air in the user's mouth. It also improves the dispersion of the aroma-enriched air towards the relevant receptors in the user's mouth as it enters the mouth. Furthermore, this reduces the likelihood of drinking liquid entering the aroma transport channel during drinking.

[0022] In one embodiment of a drinking device according to the invention, the aroma channel outlet opening can be arranged offset from the drinking liquid outlet opening, wherein, in particular, the aroma channel outlet opening has a shortest distance to the first transport channel section along an axis running perpendicular to the first transport channel section, which is less than the shortest distance of the drinking liquid outlet opening. This leads to improved mixing between the drinking liquid and the flavor-enriched air in the user's mouth. Likewise, this improves the dispersion of the flavor-enriched air towards the relevant receptors in the user's mouth as it enters the mouth. Furthermore, this reduces the probability of drinking liquid entering the aroma transport channel during drinking.

[0023] According to one embodiment, a drinking device according to the invention can further comprise a base body in which the liquid transport channel and the aroma channel are arranged. Such a design offers manufacturing advantages and simplifies the construction of the drinking device. Furthermore, it leads to improved stability. The base body is preferably made of plastic or metal. Stainless steel, for example, is a suitable metal.

[0024] In one embodiment of a drinking device according to the invention, the base body may have a receptacle for the flavor container. The receptacle may be a blind hole or a recess. The flavor container may be fully accommodated in the receptacle, or it may be provided that the flavor container is only partially accommodated and protrudes from the receptacle at one end. The other end of the flavor container may rest against an end stop of the receptacle. The diameter or cross-section of the receptacle may essentially correspond to the diameter of the flavor container.

[0025] According to one embodiment, a drinking device according to the invention can further comprise a handle, wherein the handle is, in particular, an integral part of the base body. The handle can have a curved, in particular handle-like, shape. Such a handle facilitates the handling of the drinking device and prevents the user's hands from touching the drinking liquid outlet, the aroma channel outlet, the drinking liquid inlet, the aroma channel inlet, the aroma outlet, and the air inlet. This is advantageous for hygienic reasons.

[0026] According to a further embodiment of the invention, the aroma container may comprise a carrier material for the aroma substance, wherein the carrier material particularly comprises cellulose. The carrier material may comprise any natural substance. The carrier material may comprise a textile. The carrier material may comprise a metal. The carrier material may be a woven or non-woven fabric. The carrier material may be a nonwoven fabric. The carrier material may have a porous structure.

[0027] According to a further embodiment of the invention, the flavoring agent may be distributed within the carrier material or be dispersible by actuation, particularly manual actuation. The flavoring agent may already be initially distributed within the carrier material. Alternatively, the flavoring agent may be arranged in a separate flavoring agent container, e.g., in a capsule located within or connected to the carrier material. This flavoring agent container may be opened, e.g., by squeezing, piercing, or other means, so that the flavoring agent is distributed within the carrier material. This opening of the flavoring agent container can be understood as actuation. Actuation may also be effected by actuating a separate actuating device, e.g., a piercing or crushing device.

[0028] According to a further embodiment of the invention, the drinking device can have a lid with which an opening of a drinking vessel can be covered, wherein the drinking liquid transport channel, in particular the first transport channel section, is guided through or past the lid. The lid can, for example, have a cross-section with a diameter that increases from the underside of the lid towards the top. This allows the lid to be placed on and used with drinking vessels with different opening sizes. The lid can have a round cross-section with a diameter that varies from the underside to the top. The lid can be made of an elastic material. The lid can be placed on the opening of a drinking vessel in the manner of a stopper.

[0029] The lid may also have a thread that allows it to be screwed onto the thread of a drinking vessel, such as a water bottle. The lid may have a thread compatible with a wide variety of standard threads used on drinking vessels.

[0030] According to a further embodiment of the invention, the lid may have a passage which, when the opening of the drinking vessel is covered by the lid, allows air exchange between the interior of the drinking vessel and the environment outside the drinking vessel. This facilitates pressure equalization between the interior of the drinking vessel and the environment while drinking, thus making drinking easier.

[0031] According to a further embodiment of the invention, the drinking device can include a closure device with which the opening can be closed, wherein it is particularly provided that the opening can be closed by rotating or sliding the closure device between a closing and opening position. The closure device can be a closure lug, closure cap, or the like arranged on the base body.

[0032] According to a further embodiment of the invention, a carrier unit for a drinking liquid additive can be provided, wherein the carrier unit is arranged such that the drinking liquid additive contained in the carrier unit is in contact with the drinking liquid, allowing the drinking liquid additive to be absorbed by the drinking liquid. The drinking liquid additive can, for example, be tasteless. The drinking liquid additive can be present in the carrier unit in such a way that, upon contact with the drinking liquid, it is distributed, dissolved, extracted, or carried along by the drinking liquid. The carrier unit can be sieve-like or have openings so that the drinking liquid can come into contact with the drinking liquid additive arranged in the carrier unit. For example, the drinking liquid additive can be in the form of a tablet or capsule.However, the beverage additive can also be in powder form, granules, leaf form (in the sense of crushed tea leaves), liquid form, viscous form, or other forms. The beverage additive can be contained in a beverage-soluble (e.g., water-soluble) container, such as a capsule. Upon contact with the beverage, the container dissolves, and the beverage additive can disperse in the beverage.

[0033] For example, the carrier unit can be located within the drinking liquid transport channel. The carrier unit can also be located at or near the drinking liquid inlet and / or outlet. Multiple carrier units can be provided, each containing the same drinking liquid additive or different drinking liquid additives. The carrier unit can also be located on the outside of the drinking tube, i.e., outside the drinking liquid transport channel.

[0034] The beverage additive can trigger a physical reaction in the user. For example, the beverage additive can stimulate vital bodily functions, such as metabolism, digestion, nerve function, or brain function like concentration. The beverage additive can enhance performance.

[0035] The beverage additive may be a wake-promoting substance or a stimulant.

[0036] The beverage additive may include one or more additives from the following selection: caffeine, theine, theobromine, tannic acid, essential oil, taurine, glucuronolactone, a vitamin, a mineral, an amino acid, guarana, guayusa, acetylcholine, choline, lecithin, arecoline, chlorophyll, camphor, capsaicin, cytisine, folic acid, nicotine, creatine, mesembrine, adrenaline, noradrenaline, norepinephrine, phenylalanine, piperine, piperettine, pseudoephedrine, ginseng, saponin, glucosinolate, synephrine, theopilyline, tryptophan, tyrosine, tyramine, yohimbine. The proposed drinking device allows the beverage to be enriched with a beverage additive while simultaneously creating a retronasal drinking effect for the user through the flavoring-enriched air. This means that the drinking liquid does not need to be flavored beforehand, as is the case with energy drinks, cola drinks or lemonades.The use of sweeteners or sugar can also be omitted. Thus, on the one hand, a flavor is provided (through the air enriched with the flavoring agent) and on the other hand, an additional effect is provided in the drinking liquid (through the drinking liquid additive).

[0037] According to a further embodiment of the invention, the drinking device can include a filter unit arranged such that the drinking liquid can flow through the filter, thereby filtering the liquid. For example, the filter unit can be arranged in the drinking liquid transport channel. The filter unit can also be arranged in the area of ​​or at the drinking liquid inlet and / or outlet. Several filter units can also be arranged in the drinking liquid transport channel. It can also be provided that a filter unit is arranged in the drinking liquid transport channel as well as at the drinking liquid inlet and / or outlet.A filter system can remove impurities from drinking water, such as dirt particles, microorganisms, bacteria, germs, parasites, viruses, microplastics, etc. The filter unit can be a filter membrane.
