Definitions

  • the invention relates to a drinking device for the retronasal intake of an aroma substance.
  • a first step to solve the problem is to add the flavoring to a beverage immediately before consumption.
  • US 2008/028353 A1 , US 2015/030726 A1 as well as the US 8,662,2904 are examples of dosing systems in which a flavoring substance originally intended for separate use is added to and dissolved in the drinking liquid immediately before or during consumption. While this measure can avoid problems such as stabilizing the drinking liquid over an extended period, the problem of unwanted ingestion of additives remains.
  • the drinking vessel after the US 8,662,339 B2 works on the principle that an aroma is inhaled through the nose while drinking.
  • the invention is based on the object of proposing a drinking device that provides the user with an improved taste experience.
  • the key aspect of the drinking device according to the invention is that the aroma substance is absorbed retronasally.
  • the aroma substance enters the user's mouth together with the drinking liquid during drinking and then rises retronasally through the pharynx to the olfactory mucosa (regio olfactoria), where it is detected by the receptors located there and perceived by the user.
  • the device according to the invention is equally suitable for cold or warm drinking liquids.
  • a person's sense of taste is essentially shaped by the retronasal sense of smell.
  • the receptors in the tongue can only distinguish between sweet, sour, bitter, salty, and umami, whereas the differentiated sense of taste arises when the gaseous phase of food and liquids in the throat rises via the retronasal pathway and reaches the olfactory mucosa.
  • the sensors located there trigger neurological stimuli that create a taste impression in the brain.
  • a person who is thus introduced to an aroma in the throat while drinking gets the impression that the beverage is flavored, because during retronasal smelling the brain perceives the beverage as the source of the aroma, even though the user is consuming a pure, unflavored, pure liquid, such as water.
  • the storage container which is preferably designed to be refillable, can hold pure water or carbonated water, while the aroma substance is transferred to the air in the transport channel and added to the drinking liquid immediately before it is consumed by the user or transported separately into the user's throat.
  • the drinking liquid can also have its own flavor.
  • the existing flavor of the drinking liquid is either enhanced by the flavoring substance from the flavor container or supplemented by one or more additional flavor components.
  • apple juice is present in the storage container
  • apple flavoring can be added to enhance the taste experience, or orange flavoring, for example, can be added to create a flavor blend.
  • alcoholic beverages such as beer can also be provided with additional flavoring substances, whereby the specific preferences of a user can be catered to by using a corresponding flavor container in the drinking device according to the invention.
  • flavors not commonly used in the food sector can also be used in the drinking device disclosed here, such as "sandalwood,” “spring meadow,” or "unicorn,” which are well-known in room fragrances.
  • the flavor used can be artificial or natural. It is possible to use flavors that have been isolated or enriched from an artificial or natural source, as well as natural substances, such as fresh or processed products made from, for example, lemon peel, dandelion leaves, licorice or other aromatic substances.
  • multiple aroma containers can also be provided.
  • This can be a spare aroma container that can be used as soon as the aroma container in use is exhausted.
  • it is also possible, alternatively or additionally, to use multiple aroma containers that are in use simultaneously in order to create any desired aroma mixtures from different base aromas.
  • the transport channel for drinking liquid runs to the mouth end, while the air channel either opens into the transport channel for drinking liquid in the immediate vicinity of the mouth end, or runs separately from the transport channel for drinking liquid to the mouth end.
  • the mouthpiece is designed such that the transport channel for drinking liquid and the air channel for transporting flavored air extend longitudinally at the mouthpiece separately from one another and essentially the same distance.
  • “Longitudinal direction” refers to the longitudinal direction of the transport channel for drinking liquid and the air channel for transporting flavored air at the mouthpiece. In other words, when drinking, the transport channel for drinking liquid and the air channel extend essentially the same distance into the user's oral cavity.
  • the flavored air and the drinking liquid are sucked separately from the drinking device.
  • the flavored air does not have to escape from the surrounding drinking liquid in the form of air bubbles, but can rise retronasally via the pharynx to the olfactory mucosa immediately after entering the oral cavity.
  • a further advantage of supplying the flavored air and the drinking liquid separately into the oral cavity is that there is even less mass transfer between the air and the drinking liquid. There are two reasons for this. The first reason is that the flavored air is not contained in the drinking liquid in the form of small bubbles, meaning there is a significantly smaller total surface area available for mass transfer between the liquid phase and the gaseous phase.
  • a variant of the solution according to the invention consists in that the mouth end is designed in such a way that when the drinking device is used, the transport channel for drinking liquid and the air channel for transporting flavored air extend to different distances into the user's mouth.
  • the air duct for transporting flavored air can extend further into the user's mouth than the transport duct for drinking liquid, or the transport duct for drinking liquid can extend further into the user's mouth.
  • Both solutions have in common that the flavored air and the drinking liquid are sucked out of the device separately.
  • Both variants also have in common that the exchange of substances between the flavored air and the drinking liquid is kept as low as possible. This advantage can be achieved in the same way if the transport duct for drinking liquid and the air duct for transporting flavored air extend the same distance into the user's mouth, but are both designed in such a way that they protrude into the user's mouth when used as intended. An extension too far into the mouth is perceived as unpleasant by the user.
  • the technical challenge of all the solutions described above is to coordinate the geometries of the transport channel for the drinking liquid and the air channel in such a way that, depending on the drinking position and, in the case of special drinking liquids and also the viscosity of the drinking liquid, the flavored air and the drinking liquid are sucked in in the desired ratio to each other.
  • the drinking device further comprises a throttling device and/or sealing device for the transport channel for drinking liquid and/or the air channel for transporting flavored air, wherein the sealing device is preferably provided in a mouthpiece surrounding the mouth end and the mouthpiece is movable from a sealing position to a non-sealing position.
  • a throttling device can be provided as an alternative to a sealing device, but preferably in addition to a sealing device.
  • a throttling device makes it possible to adjust the ratio between drinking liquid and flavored air, which, for example, allows the degree of flavoring or the flow rate of drinking liquid to be adjusted.
  • a simple embodiment of a throttling device, which can be actuated until complete sealing is achieved, is a squeezing device, with the aid of which a flexible section of the transport channel or air channel can be reduced in terms of its internal cross-section or completely clamped off.
  • a preferred alternative embodiment of the sealing device is the provision of a pull-tap, preferably located on the mouthpiece, which is pulled out by the user to open the flow. After drinking, the pull-tap is pushed back toward the mouthpiece to close the air channel and the transport channel.
  • Another preferred alternative to the drinking device according to the invention comprises a rotary plug, which is opened or closed by the user by turning it.
  • rotary plugs are well known in chemical engineering, as a rotary plug represents a simple but very tightly sealed component.
  • a rotary plug can also be continuously adjusted, so that a rotary plug combines the functions of a throttling device and a shut-off device.
  • Another preferred alternative of the device according to the invention comprises a sliding valve, which, according to a preferred variant, is provided in a lid of the drinking device and can simultaneously contain the mouthpiece.
  • a sliding valve which, according to a preferred variant, is provided in a lid of the drinking device and can simultaneously contain the mouthpiece.
  • a preferred alternative embodiment of the device is the provision of a twist-on lid, which is either placed on or screwed on, thereby sealing the drinking device.
  • a twist-on lid is well suited to tightly closing the drinking device even when increased pressure builds up inside the storage container, as can occur when the drinking liquid is a carbonated beverage.
  • Such a lid can tightly close both the transport channel for drinking liquid and the air channel for flavored air, but also an additional air line for supplying air into the interior of the storage container for the purpose of pressure equalization.
  • a further advantage of a twist-on lid is that it protects the mouthpiece from contamination and is a familiar element to every user, whose suitability for tightly closing the drinking device is trusted.
  • a preferred alternative embodiment of the device is the provision of a sports valve, as is known from drinking bottles, for example, for cycling. Accordingly, the function of a sports valve is known, so that the user intuitively pulls the valve to drink and pushes it back into its original position after drinking.
  • the embodiment in which the mouthpiece of the drinking device simultaneously functions as a shut-off device is particularly preferred, allowing all transport paths leading toward the mouthpiece to be tightly closed.
  • the mouthpiece is designed such that it can be moved from the sealing position to the non-sealing position via a translational movement.
  • the mouthpiece can be designed such that both the transport channel for drinking liquid and the air channel, as well as the air line for air flow into the interior of the storage container, can be sealed and opened. Consequently, the user only needs to move the mouthpiece into an operating position, which activates the sealing device unnoticed by the user. This allows the number of components to be kept to a minimum, which, among other things, enables a more hygienic design and also saves costs in the production and assembly of the drinking system.
  • the at least one aroma container is removable and can be inserted into the drinking device according to the invention with the aid of a simple movement sequence.
  • a bayonet closure can be used.
  • a bayonet closure has the advantage that, after insertion, the correct orientation of the aroma container in the drinking device is ensured.
  • a spring element can additionally be provided which allows the aroma container to emerge from its receptacle as soon as the aroma container has not been inserted correctly.
  • different locking positions can be used to preselect between different aroma intensity settings.
  • one of the at least one aroma container comprises a sealing device, wherein the aroma container is movable from a sealing position to a non-sealing position.
  • a aroma container with a substantially circular cross-section can be used in the same way as the rotary plug described above, by rotating the aroma container about its axis of symmetry to bring the transport channel for drinking liquid into alignment with the channel through the aroma container. The advantage of this solution is that no additional component is required.
  • the aroma container from a sealing position to a non-sealing position by sliding the aroma container in an axial direction.
  • an aroma container with any prism-shaped or ring-shaped geometry could be pushed in an axial direction to move the aroma container into a non-sealing position.
  • the aroma container can lock into this position, i.e., remain in this position automatically, or drinking with aroma delivery is only possible if the aroma container is held down. In this way, a user could also choose between drinking liquid with or without flavored air.
  • At least one of the at least one aroma container can comprise a plurality of chambers containing aroma substances of different odor intensities and/or different odor qualities.
  • a plurality of aroma containers can be provided.
  • one or more aroma containers can be provided, and this aroma container or any number of the plurality of aroma containers can additionally comprise a plurality of chambers. In this way, any desired variants can be realized. If a single aroma container is provided, it can contain different aromas, so that a different aroma is supplied depending on the direction of insertion or an orientation of the aroma container, which can also be changed by the user during drinking.
  • the aroma container allows the type of aroma as well as the aroma strength to be varied.
  • an aroma container could contain two, three, or more different aroma intensities of one and the same aroma substance, or a single aroma container could contain two different aromas, each at two different levels, so that the aroma container would have four separate chambers.
  • any desired aroma mixture can be created by varying different aroma directions, aroma strengths, or by adding one and the same aroma direction, which can be individually composed by a user.
  • one of the at least one aroma container is located in a mouthpiece of the drinking device, wherein the mouthpiece is preferably replaceable.
  • the advantage of having the aroma container either integrated into the mouthpiece or attached to a lid of the reservoir is that it allows the user to immediately identify the "flavor.”
  • the mouthpiece could be colored according to the selected flavor, such as yellow for a lemon flavor or green for a green apple flavor.
  • the storage container for drinking liquid is provided with a lid.
  • the lid When the lid is removed, the user has access to both a filling opening for drinking liquid and a receiving opening for one or more aroma containers. After replacing the lid, the user can then vary between different aroma directions by rotating the lid.
  • the advantage of this solution is also that no separate locking of the aroma container is required in the drinking device according to the invention, because the aroma container is automatically fixed in the inserted state after the lid is replaced. This solution also makes sealing the aroma container easier.
  • an information tab is provided on the aroma container, which protrudes outwards from the drinking vessel after the lid has been put on and informs a user about the inserted
  • the tab is easy to grasp to remove the aroma container.
  • the aroma container is designed as a ring located near the mouth end of the drinking device.
  • a single chamber can be located within the ring.
  • the ring-shaped aroma container can contain multiple chambers with different flavors, which are preferably identified for the user by additional marking and/or coloring. In this way, the user can intuitively change the aroma by operating the aroma ring, which can also be done while drinking.
  • the use of a aroma container in the shape of a ring offers many options that can be used in a user-friendly manner.
  • the drinking device further comprises a pull valve as a pressure equalization valve, which closes an air supply line leading into the interior of the storage container for drinking liquid. If a negative pressure builds up in the storage container due to drinking, i.e., the withdrawal of drinking liquid, the valve opens and allows air to enter the storage container for drinking liquid. As soon as the pressure is equalized, the pressure valve automatically closes again due to its inherent tension, so that no drinking liquid can escape.
  • This variant is particularly advantageous in cases in which the shut-off device only closes the transport channel for drinking liquid and the air channel for transporting flavored air, but not the air channel for pressure equalization.
  • An exemplary variant of this type is the provision of a mouthpiece that can be pivoted from a sealing position to an operating position, while the air line for pressure equalization is located at a different location in the container.
  • the drinking device further comprises a head part which comprises the mouth end and is arranged to be movable relative to the storage container, wherein the head part is movable from a position sealing the transport channel for drinking liquid and/or the air channel to a non-sealing position.
  • the head of the drinking device can be pivotally attached to the reservoir for the drinking liquid.
  • the geometry of the head relative to the reservoir can be selected such that when the head is rotated into the drinking position, it is angled. This allows the user to adopt an ergonomically comfortable drinking position and also makes it clear to the user that the drinking device is in its ready-to-use state and that improper handling could result in the drinking liquid leaking out. In this way, a drinking device can be designed with a futuristic design language that underscores the claim to be a new and innovative drinking device.
  • the drinking device can be designed in a variety of ways. It can be a mobile drinking bottle, which is either single-walled or double-walled as a thermos flask.
  • An open drinking vessel similar to a mug, can also be provided, although care must be taken to ensure the correct drinking position so that both the drinking liquid and the aroma to be dosed are directed into the throat when drinking.
  • the aroma container could be a ring surrounding the storage container for the drinking liquid and from which the aroma is either dosed into the transport channel for the drinking liquid or supplied to the user via a separate air duct running along the rim of the drinking cup.
  • the drinking cup can also be closed at the top and used as a so-called shot glass.
  • This variant can be used to modify the taste of drinking liquids such as spirits, liqueurs, or even caffeinated or non-caffeinated beverages with certain flavorings, or to enhance an existing flavor or mask potentially unwanted sensory perceptions.
  • a further alternative design consists in integrating the special functional features of the drinking device according to the invention into a straw which contains the mouth end and whose end opposite the mouth end is located in the storage container for drinking liquid.

  • the aroma container 20 is shown in this embodiment as a ring which surrounds the outer periphery of the storage container 12 and can either, as in Fig. 23c shown, is connected to the transport channel 18 for drinking liquid via a short air channel 22 for transporting flavored air, or, as in Fig. 23c not shown, has an air channel that runs parallel to the transport channel for drinking liquid and up to the mouth end 28.
  • the drinking cup as shown in Fig. 23b shown, the drinking liquid from the mouth end 28 (see Fig. 23a ) is sucked in, whereby, as in Fig. 1 As shown, the drinking liquid mixed with bubbles of flavored air is sucked in.
  • a parallel routing of the transport channel 18 for drinking liquid and the air channel 22 for transporting flavored air is conceivable.
  • the open drinking vessel shown could be a shot glass, which functions according to the same principle as the open drinking vessel and can also be used, for example, for spirits that are to be given additional flavor aromas.
  • FIG. 24a and 24b A further embodiment of the invention is shown.
  • the special feature of this embodiment is that the head part 14 can be screwed onto any bottle serving as a storage container 12.
  • An aroma container is permanently installed in the head part 14, which transports the aromatized air via an air duct 22 (not shown) either parallel to the transport channel 18 for drinking liquid to the mouth end 28 or, according to the schematic representation in Fig. 1 opens into the transport channel 18 shortly before the mouth end 28.
  • Fig. 24a and 24b A conventional bottle containing pure drinking liquid can be used, which can be reconfigured as desired by replacing the head portion 14 with the connected intake hose 80.
  • This embodiment is particularly advantageous in regions where tap water is undrinkable due to inadequate quality, allowing consumers to purchase pure water as a drinking liquid, which can be modified to any desired flavor via the bottle attachment.
  • the drinking device 10 consists of the storage container 12 designed as an open glass, as well as a drinking straw 82 to be arranged in the storage container, which combines the components and functionality of the intake hose 80, the transport channel 18 for drinking liquid, and, due to the aroma container 20 arranged in a ring around the drinking straw, also the air channel 22 for transporting aromatized air.
  • the drinking straw 82 can be combined with any storage container 12, wherein the aroma container 20 is preferably not interchangeable but firmly connected to the drinking straw.
  • FIG. 26a and 26b an embodiment is shown in which the illustrated head part 12 of the drinking device 10 (not shown) can be turned upside down during drinking, as consumers are familiar with, for example, drinking devices using a sports valve.
  • the special feature of the embodiment according to Fig. 26a and 26b is that neither a suction tube 80 nor a drinking straw 82 is required. Without these elements, the drinking system according to the invention is easier to handle hygienically. Furthermore, this embodiment reduces the number of individual components, thereby simplifying production and shortening the assembly of the system. Furthermore, the consumer is accustomed to tilting his drinking bottle from conventional systems.
  • Fig. 26a and 26b In contrast to the previously described embodiments, no liquid is accidentally spilled from the reservoir 12 during normal use.
  • Fig. 26a and 26b The illustrated head part 14 can be connected to a storage vessel 12 via the illustrated thread 84 or another fastening option, whereby care must be taken to ensure that the connection prevents liquid leakage.

  • the aroma container is shown as a wide ring 83, the functional principle of which corresponds to the aroma container 20.
  • the aroma reservoir is fluidically connected via the air channel 22.
  • a movable mouthpiece (not shown here) must be pushed into the opening 86.
  • This mouthpiece corresponds to a conventional mouthpiece of sports drinking bottles and must be made of a substantially flexible material. By sliding in the direction K, the mouthpiece (not shown) opens and closes the drinking device 10.
  • FIG. 27a and Fig. 27b A preferred embodiment of the drinking device according to the invention is shown with a modification of the liquid channel 18 at the mouthpiece 16 in the head part 14 of the drinking device. It enables Fig. 27a shown taper 19 or the one in Fig. 27b
  • the widening 23 of the channel at the mouthpiece 16 shown in FIG. 1 changes the pressure conditions in the liquid-air mixture. This changes the shape and size of the air bubbles, resulting in a more pleasant drinking experience.
  • FIG. 28a and Fig. 28b A further preferred embodiment of the improvement of the drinking device 10 is shown in the Fig. 28a and Fig. 28b
  • the preferred embodiment of the improvement according to the invention provides that the liquid channel 18 in the reservoir 12 of the drinking device 10 is tapered ( Fig. 28a - paragraph 21) or extended ( Fig. 28b - Number 25).
  • the required suction pressure is essentially determined by the hydrostatic gravitational pressure of the liquid and the friction loss of the fluid on the wall of the liquid channel 18.
  • the hydrostatic gravitational pressure is invariably directly proportional to the fill level in the storage container 12 and noticeably influences the suction pressure required by the drinker.
  • this negative change can be partially or completely compensated for and thus the drinking experience can be improved.
  • the pressure differences can be reduced by using a substantially wide but flat storage container (not shown here).
  • FIG. 29 Another, in Fig. 29
  • the preferred embodiment of the drinking device 10 shown in FIG. 1 provides that the air channel 22 in the head part 14 is tapered only at one point 27 and the air channel otherwise has a wider cross-section. This has the advantage that, despite the required small cross-section, in particular diameter, of the air channel 14, it is easier to produce and clean.
  • liquid which flows from the liquid channel 18 into the air channel 22 can easily flow back into the liquid channel 18, resulting in hygienic advantages.
  • FIG. 30a and Fig. 30b shown schematically.
  • the head part 14 can be divided essentially axially symmetrically into two parts 14a and 14b. Both parts 14a, 14b contain on the inside a part of the air channel 22 and the liquid channel 18, which, when the two halves 14a, 14b are joined together in the direction of arrow C, form-fit the channels required for the drinking device.
  • a fastening device 29, which in the Fig. 30a and Fig. 30b preferred embodiment is shown as a ring, can be reversibly held together by a displacement in the direction of arrow D on the two parts 14a and 14b.
  • the separable head part 14 is shown in the drinking position.
  • the recess 66 for the aroma reservoir 20 (not shown) is also cylindrical.
  • a seal can be achieved by manufacturing the head part 14 from a substantially flexible material.
  • a further preferred embodiment of the divisible head part 14 is shown in Fig. 31 shown.
  • the recess 66 for the aroma reservoir 20 is also possible in the head section. Integration into the interior of the head section offers the advantage that the aroma reservoir 20 is not visible from the outside when the head section is closed. The aroma reservoir therefore needs to be designed less complexly, among other things, and evaporation of the aroma substance from the aroma reservoir during storage is slowed down.
  • the aroma reservoir is inserted by joining the two parts 14a and 14b along the direction of arrow E. The two parts of the head section 14 are held together by a mechanism not shown here.
  • FIG. 32a A further embodiment for optimizing a drinking device according to the invention is shown by way of example in the Fig. 32a, 32b and 32c
  • Fig. 32a A preferred embodiment is shown in Fig. 32a the head part 14 of a drinking device is shown, which contains a liquid channel 18 and an air channel 22.
  • Fig. 32a A fluid channel with a uniform shape over its entire length is shown.
  • a preferred embodiment of a head part 14 of a drinking device in which the liquid channel 18 has a smaller diameter at the connection point of the liquid channel 18 with the air channel 22 than at the other points.
  • the speed of the liquid increases in proportion to the cross-sections when flowing through the constricted part, since the amount of liquid does not change.
  • the pressure in the air channel 22, which is attached at the narrowest point decreases. This creates a pressure difference that increases the absorption of the flavored air into the liquid in the drinking device.
  • This effect known as the Venturi effect, significantly improves the drinking device.
  • a further preferred embodiment is in Fig. 32c shown as an example and provides that a liquid channel 18 and an air channel 22 are arranged in the head part 14 of the drinking device, wherein at the connection point of the two channels, at least one of the two channels is wider than the cross-section of the other regions of the respective channels. This also enables a modified drinking experience for the user of the drinking device.
  • FIG. 33a and 33b A further preferred embodiment of the head part 14 is shown in Fig. 33a and 33b shown as an example and provides that the air channel 22 is interrupted by a chamber 87 designed essentially as a recess on the outer wall of the liquid channel 18.
  • the interruption of the air channel by a chamber 87 is designed such that a recess is provided in the head part 14 of the drinking device at the contact point between the removable riser 18 for the drinking liquid (liquid channel) and the air channel 22.
  • the air channel 22 opens from the aroma container 20 into the chamber 87 at an upper position.
  • the air channel is continued as channel 22b through the transport channel 18 at a lower position of the chamber 87.
  • the chamber designed in this way prevents the drinking liquid from backflowing into the aroma reservoir 20.
  • the opposite position of the continuation of the air channel 22 ensures the best possible use of the chamber 87.
  • the different height positions of the inlet and outlet openings of the air duct 22 in and out of the chamber 87 enable, among other things, the drainage of drinking liquid back into the drinking liquid transport channel 18.
  • the arrangement of the chamber 87 at the contact point between the head part 14, which can be made of a substantially elastic material, for example, and the drinking liquid transport channel 18 facilitates cleaning after disassembly of the components.
  • Fig. 33a and Fig. 33b the air supply line 32 through the head part 14 into the storage container 12 for drinking liquid (not shown).
  • Fig. 33b shows the embodiment of the head part 14 of the drinking device according to Fig. 33a in section, which illustrates the positions of the chamber 87 and the entry point of the air duct 22 as well as the exit point from the chamber 87 into the continuation of the air duct 22b.
