Description

Field of invention

The invention relates to an aroma container and a drinking device with such an aroma container.

State of the art

There is an increasing need to take in drinking liquids which, on the one hand, have a pleasant taste, but on the other hand, avoid health risks that can be caused by the absorption of aroma substances or stabilizers dissolved in the drinking liquid. In addition, the intake of an increased amount of calories should be avoided.

Therefore, water provided with a weak fruit flavor has become popular in recent years. However, undesirable additives such as stabilizing substances and a certain amount of sugar can also be found in this flavored water. Many users already reject such drinks because of this amount of calories.

Since the olfactory sensory impression makes up an essential part of the gustatory perception when consuming food and drinks, previous drinking systems try to influence the smell perceived when drinking. For this purpose, aroma elements are proposed which can be attached to a drinking container near the drinking opening so that the aroma element is in close proximity to the nose of the user who breathes through the nose while drinking and thus absorbs the scent.

From the WO 2019/016096 A1 a drinking device is known for the retronasal uptake of an aroma substance with an aroma container through which air can flow and which supplies aroma air to a transport channel for drinking liquid. In this way, the aroma substance is absorbed retronasally. The aroma substance reaches the mouth of the user together with the drinking liquid while drinking and then rises retronasally via the pharynx to the olfactory mucosa, where it is detected by the receptors located there and perceived by the user. One makes use of the fact that there is a close connection between the sense of smell and the sense of taste. The user therefore gains the impression that he is tasting the aroma, even though he is actually only smelling it retronasally.

Presentation of the invention

The invention is based on the object of proposing an aroma container for adding an aroma substance to an air stream flowing through the aroma container, which allows an improved enrichment of the air through which the aroma substance flows.

This object is achieved by an aroma container with the features of one of claims 1 to 5 and by a drinking device with the features of claim 22. Preferred embodiments follow from the remaining claims.

The aroma container according to the invention for adding an aroma substance to an air stream flowing through the aroma container comprises an upper wall, a lower wall and at least one side wall which enclose an aroma chamber, at least one air inlet opening into the aroma chamber and at least one air outlet opening from the aroma chamber. A carrier substance for the aroma substance is located in the aroma chamber. In addition, a head space is preferably provided between the carrier substance and the side of the upper wall facing the aroma chamber. Furthermore, according to the invention, the carrier substance comprises a fleece material, the air permeability L of the fleece material at 100 Pa differential pressure L ≥ 200 1 / (m ² • s), and preferably between 220 1 / (m ² • s) and 280 1 / (m ² • s) s) is.

In the aroma chamber there is thus a carrier substance for the aroma substance and preferably a head space between the carrier substance and the wall closing off the aroma chamber at the top. The provision of a headspace improves the mixing of the flavored air stream. The air flow flowing through the aroma chamber flows through the carrier substance which is provided with the aroma substance. In the process, different partial flows form within the carrier substance, which comprises a fleece material, which can be flavored to an unequal degree, especially if the aroma container has been in use for a long time and there is no longer as much aroma substance in the carrier substance. When the air flows through the headspace, which is a cavity within the aroma chamber that is not filled with carrier substance, the partial air currents, which may have different degrees of aromatization, are homogenized. The provision of a headspace thus ensures that the user of a drinking device who, in addition to drinking liquid, receives the flavored air stream, experiences a taste experience that is as uniform as possible.

Another benefit of the headspace is the aromatization of the airflow with it to homogenize different aromatic substances. Numerous aroma substances do not consist of a single chemical compound, but rather comprise a large number of chemical compounds, the mass transfer behavior of which differs from the carrier substance into the air stream. Individual partial air flows emerging from the carrier material can therefore have a different chemical composition of the aromatization. By mixing the partial air flows in the head space, an air flow is generated which is provided as homogeneously as possible with aroma substance with the desired composition of the chemical compounds.

Another important aspect is that the air permeability of the nonwoven material at 100 Pa differential pressure is more than 200 1 / (m ² • s). Such air permeability of the nonwoven material ensures that the air flow flowing through the aroma container ensures a good flow, but at the same time there is no excessive pressure loss that would make it difficult to dispense the flavored air into the transport channel for drinking liquid of an associated drinking device.

The interplay of a carrier substance comprising a fleece material that does not fill the entire aroma chamber, but leaves a head space, is therefore important, as well as the suitable selection of a high air permeability of the fleece material, which should not be less than 200 1 / (m ² • s).

The air permeability L of the nonwoven material at 100 Pa differential pressure is preferably not more than 500 1 / (m ² · s). If the air permeability becomes too high, there is a risk that preferred flow paths will form within the fleece material, through which the air flow flowing through the aroma container can flow with very little resistance, so that the air flow only has a slight tendency towards other areas of the fleece material to flow through and to absorb the aroma substances present there. This would lead to the air flow emerging from the aroma container showing a decreasing degree of aromatization long before the aroma substance is actually exhausted.

The carrier substance in the aroma chamber does not have to have the same extent as the geometry of the aroma chamber. In addition to the head space provided in the vertical direction between the carrier substance and the upper wall, there can also be one or more zones in the lateral direction in the aroma container in which the carrier substance is not located and in which there is an increased homogenization of the air flow flowing through the aroma container can.

If different aromas are used in a drinking device, the most suitable geometry can differ between the individual aroma substances in terms of the size of the head space, but also the lateral extension of the carrier substance in the aroma chamber. Different aroma substances have a different chemical structure, which influences their behavior with regard to the transfer of substances into the air flow.

If the carrier substance does not cover the entire lower wall of the aroma chamber, this can also have the advantage that, in the case of complex geometries of the cross-sectional area of the aroma chamber, the insertion of the carrier substance in production is simplified.

The carrier substance is preferably on the side of the lower wall facing the aroma chamber.

According to an alternative embodiment of the invention, the side wall of the aroma container comprises, at least in sections, a projection which preferably extends outwardly essentially perpendicular to the outer side wall.

On the one hand, such a projection facilitates manual handling by a user who, in addition to suitable labeling, can use the projection to identify the orientation in which the aroma container must be coupled to an associated drinking device. In addition, as will be explained later, a projection extending outward from the side wall can be used to automatically move the aroma container into an operating position and, conversely, also to bring it into a position in which, in cooperation with a correspondingly designed drinking device the aroma container can also be stored for a longer period of time because unwanted evaporation of the aroma container is prevented.

According to an alternative solution according to the invention, the nonwoven material has a specific flow resistance of less than 500 Pa · s / m and preferably below 400 Pa · s / m and most preferably of about 380 Pa · s / m. According to the usual definition, the ratio of the pressure difference in front of and behind a material layer to the speed of the air flowing through is referred to as the specific flow resistance.

According to a further alternative solution according to the invention, the nonwoven material has a weight per unit area of less than 1500 g / m ² and preferably of about 1000 g / m ^2, and the nonwoven material has a Density of less than 300 kg / m ³ and preferably a density of about 200 kg / m ³ .

The weight per unit area, the maximum density but also the preferred specific flow resistance have proven to be particularly suitable parameters for a good flow through the carrier substance in the aroma chamber, but also a good enrichment of the air with aroma and an improved aroma development when using the aroma container in to enable an associated drinking device.

100% polyester is also preferred as the nonwoven material, since it is an inert material that does not interact with the aromatic substances in any undesired manner.

Furthermore, it has proven to be advantageous to arrange the carrier substance with a thickness of 2 mm to 10 mm and preferably of about 5 mm in the aroma chamber.

According to a preferred embodiment of the invention, the thickness of the carrier substance is at least 50% of the height between the upper wall of the aroma container and the lower wall of the aroma container and preferably at least 80% of the height between the upper wall of the aroma container and the lower wall of the aroma container. If the upper wall and the lower wall of the aroma container do not run parallel to each other, the geometrically averaged thickness of the carrier substance and the geometrically averaged height of the aroma chamber in the area of the carrier substance are to be used.

If the thickness of the carrier substance is less than 50% of the clear height within the aroma chamber, there is no longer a sufficient flow through the nonwoven material. In order to ensure a good flow through the nonwoven material, the thickness of the carrier substance is therefore particularly preferably at least 80% of the height between the upper wall of the aroma container and the lower wall of the aroma container.

Another preferred embodiment provides that the carrier substance consists of more than one part, as is the case, for example, with granules. Likewise, the carrier material can be divided at least once essentially longitudinally or transversely with regard to both the fiber direction of the material and with regard to the geometry of the aroma chamber. This enables easier filling of the aroma chamber with the carrier material.

A particularly preferred embodiment of the carrier material provides that an aroma substance is added to it before it is inserted into the aroma chamber, or an aroma substance is added to it during or after it is inserted into the aroma chamber. Likewise, the present invention can also be filled by the user himself or designed to be refillable.

The height between the top wall and the bottom wall defines the height of the internal volume of the aroma chamber. The head space above the carrier substance in the area of the carrier substance should consequently not be more than half the height of the aroma container between the upper wall and the lower wall.

According to a preferred embodiment of the invention, the at least one air inlet opening has a diameter of at least 0.2 mm or a different geometry with an equivalent minimum opening cross section.

An opening cross-section of the air inlet opening less than 0.2 mm results in too high a pressure loss and therefore makes it difficult for the aroma container to flow through. In addition, a further reduction in the opening cross-section of the air inlet opening has no advantages with regard to the flow regime prevailing in this area, which is already in the turbulent area under normal operating conditions.

The porosity of the nonwoven material is preferably between 70% and 93% and preferably between 70% and 80%.

A high porosity of the nonwoven material is not only important with regard to good permeability and a low specific flow resistance, but also enables the carrier substance to absorb a lot of aroma substance, so that an aroma container with small dimensions has a long service life until the supply of aroma substance is exhausted owns.

According to a preferred embodiment of the invention, the Reynolds number Re in the air inlet area of the aroma container is greater than 2000, the Reynolds number being defined as Re = (w • d) / υ, with the kinematic viscosity of air υ [m ² / s], the diameter d [m] of the air inlet opening and the flow velocity w [m / s] when flowing into the aroma container with a time-averaged volume flow between 250 ml / min and 600 ml / min.

A Reynolds number greater than about 2000 characterizes a turbulent flow or at least a flow that is already in the transition area between laminar and turbulent flow. A turbulent flow ensures good mixing, which means that the aroma substance is taken up in the aroma container air flow flowing through is improved. The volume flow per minute takes into account the sometimes considerable fluctuations in the temporary volume flow when the aroma container according to the invention is coupled to a drinking device and the air outlet opening is in flow connection with a transport channel for drinking liquid. Since the drinking process is not a steady, stationary process, but rather different pressures and different flow velocities prevail in the transport channel for drinking liquid within the framework of the suction and swallowing processes, there is a considerable fluctuation of the temporary volume flows and thus also the flow velocities with which the air passes through the air inlet opening passes through. However, it could be shown experimentally that an aroma container according to the invention, when used as intended, is flowed through with an averaged volume flow between 250 ml / min and 600 ml / min. The physiological drinking process was determined in numerous, different, adult people. Since the volume flow is the product of flow velocity and cross-sectional area, given that the Reynolds number describing the flow state must be greater than 2000, a suitable range for the opening cross-section of the air inlet opening can be determined.

The air inlet opening preferably has a diameter of between 0.2 mm and 20 mm. A relatively large air inlet opening of 20 mm cannot ensure a turbulent flow directly in the area of the air inlet opening, but this can be compensated for by a suitable choice of the geometry of the aroma chamber, for example by the carrier substance in the aroma chamber lying directly on the air inlet opening and thus the one in the Aroma chamber entering air stream within the nonwoven material flows through the carrier substance in a turbulent manner.

According to a preferred embodiment of the invention, the aroma container has a substantially annular geometry with an outer side wall and an inner side wall.

Such a geometry has numerous advantages. On the one hand, such an aroma container can be fastened around the transport channel for drinking liquid on the head part of a drinking device without the weight of the aroma container being perceived as disturbing, since there is no asymmetrical weight distribution on the drinking device. In addition, by providing an annular geometry through the arrangement of the air inlet opening and the air outlet opening, it can be ensured that the air flow flowing through the aroma container covers the longest possible path and thereby flows through the carrier substance contained in the aroma chamber as completely as possible.

In the case of an aroma container with an essentially ring-shaped geometry, the inner side wall preferably encloses a space whose cross-sectional area has a geometry that deviates from a circular shape.

This design has numerous advantages, as will be described using several examples. On the one hand, the friction between the inner side wall and a head part of a drinking device on which the aroma container is placed can be reduced in a targeted manner. In addition, a non-circular shape can be used to move the aroma container in cooperation with a suitably designed drinking device between different operating positions. Finally, a non-circular shape can also be used to make it easier for a user to correctly place the aroma container on a drinking device.

In this context, it is particularly advantageous to design the aroma container in such a way that the geometry of the inner side wall defines only a single position of the aroma container in relation to its rotation in cooperation with a correspondingly shaped mouthpiece of a drinking device, preferably the space enclosed by the inner side wall has a substantially teardrop-shaped cross-sectional area.

In other words, the geometry of the inner side wall of the aroma container is selected such that the space enclosed by the inner side wall has a cross-sectional area that allows the aroma container to be clearly positioned. A hexagonal geometry of the inner side wall could not achieve this, for example. The space enclosed by the inner side wall would have a geometry of the cross-sectional area that deviates from a circular shape, but the aroma container could be placed on a correspondingly shaped mouthpiece that fills the inner space in six different rotational positions.

und bevorzugt $${\text{L}}_{\text{max}}/{\text{L}}_{\text{min}}\text{ etwa }1.1$$

beträgt.It has been shown to be particularly advantageous if, in the case of an essentially ring-shaped geometry of the aroma container, but whose cross-sectional area deviates from a circular shape, for the ratio between a maximum extent (L _max ) of the cross-sectional area of the space enclosed by the inner side wall and the minimum Extension (L _min ) of the cross-sectional area of the space enclosed by the inner side wall applies: $$1.05\le {\text{L.}}_{\text{Max}}/{\text{L.}}_{\text{min}}\le 1.15;$$

and preferred $${\text{L.}}_{\text{Max}}/{\text{L.}}_{\text{min}}\text{approximately}1.1$$

amounts to.

A geometry of the essentially ring-shaped aroma container that deviates from a circular geometry has proven to be advantageous not only with regard to possible clear positioning options, but also has the effect that the air flow flowing through the aroma container is better mixed by changes in cross-section and changes in the curvature of the aroma chamber because any changes in the flow pattern encourage turbulence to occur. If the ratio between the minimum extent and the maximum extent were too great, then this would again have negative effects with regard to the distance to be traversed by the air stream in relation to the volume of the aroma chamber. Here the optimum is achieved with a purely circular ring shape. The range between values of 1.05 and 1.1 for L _max / L _min thus represents the best possible compromise between the longest possible distance for the air flow flowing through the aroma container on the one hand and supporting the occurrence of turbulence and / or maintaining existing turbulence on the other.

The aroma container preferably further comprises sliding ribs in the area of the inner side wall. The provision of sliding ribs reduces the friction when the essentially ring-shaped aroma container is pushed onto a drinking device by reducing the contact area between the aroma container and the mouthpiece of the drinking device that extends in the space enclosed by the inner side wall.

In the same way, however, it is also possible to provide grooves, which are provided in the inner side wall, instead of providing sliding ribs. This measure also reduces the potential contact area between the aroma container and a possible design of the drinking device and, associated therewith, the friction during a relative movement between the two components.

If the grooves in the inner side surface of the aroma container extend sufficiently deep inward in the direction of the aroma chamber, this leads to the fact that on the side of the inner side wall facing the aroma chamber there are elevations which extend into the aroma chamber and also repeat through the Separation of the flow of the air stream along the inner side wall supported the mixing of the air stream flowing through the aroma container.

In the same way, it is also possible to reduce the friction in that the inner side wall of the aroma container does not correspond in some areas to the outer shape of the head part of the drinking device and therefore there is no full-surface contact between the aroma container and a drinking device.

According to an alternative design of the aroma container according to the invention, the air inlet opening is located in the area of the lower wall of the aroma container, and the air outlet opening is arranged in a side wall of the aroma container, preferably in an inner side wall in the case of a substantially annular geometry of the aroma container with an outer side wall and a inner side wall.

The provision of the air inlet opening in the area of the lower wall of the aroma container is advantageous if the aroma container is to be attached to the head part of a drinking device and there is to come into sealing contact with the head part of the drinking device. In addition, by providing the air inlet opening in the area of the lower wall of the aroma container and depending on the arrangement of the carrier substance in the aroma container, a flow through the flow container can be generated in which the air flow when flowing through the aroma container must flow through the carrier substance and not directly into the one provided in the aroma container Headspace flows.

The provision of the air outlet opening in a side wall of the aroma container opens up the possibility of generating a defined and long path for the air stream flowing through the aroma container. For example, the air outlet opening can be located in an area in which the carrier substance in the aroma chamber is in contact with the air outlet opening. In this way, the air stream flowing through the aroma container has to flow through the carrier substance before exiting the aroma container and can exit from there through the air outlet opening.

In the case of an essentially ring-shaped geometry of the aroma container with an outer side wall and an inner side wall, the air outlet opening is preferably located in the inner side wall of the aroma container, so that the flavored air exiting the aroma container can enter a transport channel for drinking liquid that passes through extends the space enclosed by the inner side wall of the aroma container.

According to a preferred embodiment of the invention, the aroma container comprises a lower shell and an upper shell connected to the lower shell, the air outlet opening being arranged in the connection area between the upper shell and the lower shell.

This design has the advantage that it can be implemented in a technically simple manner in the context of production using an injection molding process. No slider is required to create the air outlet opening.

There is preferably a circumferential groove in the contact area between the lower shell and the upper shell, which serves as a shadow gap and can fulfill several functions. On the one hand, such a shadow gap can indicate to the user the position of an aroma container that can be displaced relative to the head part of a drinking device. On the other hand, the lower shell and the upper shell can be connected to one another by ultrasonic welding without the risk that a possible accumulation of material in the area of the weld seam extends outwards over the outer surface of the outer side wall.

According to a second aspect of the invention, this relates to a drinking device, comprising an aroma container according to the invention, as well as a head part with which the aroma container can be connected in such a way that at least part of the aroma container can be moved from an activated position to a non-activated position, in which case the activated Position the air outlet opening is in flow connection with a transport channel for drinking liquid in the drinking device, and in the non-activated position there is no flow connection between the air outlet opening and the transport channel for drinking liquid, and the air inlet opening is essentially sealed.

When moving from an activated position to a non-activated position, it is possible that the aroma container is completely moved, e.g. by a translational movement or a rotational movement. It is also possible that only at least part of the aroma container can be moved from an activated position to a non-activated position. For example, two parts of the aroma container that can be moved relative to one another can be moved relative to one another by rotating them relative to one another. It is also possible to activate two parts of the aroma container by pulling them apart or pressing them together, whereby the air outlet opening and / or the air inlet opening in the respective parts of the aroma container can be brought into an aligned position by pulling the two parts apart. In the simplest case, two housing parts can be rotated against each other in an annular aroma container and only in a defined rotational position are air outlet openings provided in both housing parts in an aligned position and the aroma container in the activated position.

The drinking device is further characterized in that, in the activated position, the air outlet opening of the aroma container is in flow connection with a transport channel for drinking liquid. The flavored air flow is therefore not released into the surrounding air in order to have an orthonasal effect on a user, but is fed into the transport channel for drinking liquid, so that the flavored air is perceived retronasally by the user and the sensory impression of a taste perception of the drinking liquid is created.

The drinking device preferably comprises a removable lid which can be attached to the head part of the drinking device, the removable lid comprising at least one force-exerting element with which the aroma container can be moved from a non-activated position to the activated position when the lid is removed.

Moving the aroma container between the non-activated position and the activated position extends the useful life of the aroma container, since it does not inadvertently evaporate when it is not in use. The movement of the aroma container between the non-activated position and the activated position can be carried out by the user himself, but there is always the risk that the user will forget this. Therefore, the solution is advantageous to provide the drinking device with a removable lid. This must be removed if you want to drink from the drinking device. If the drinking device comprises a force-exerting element with which the aroma container can automatically be moved into the activated position when the lid is removed from the non-activated position, the drinking device is automatically in a ready-to-use state with the aroma container in the activated position after the lid has been removed.

In the same way, it is also possible to use the attachment of the lid after the drinking process to bring the aroma container into the non-activated position.

According to a preferred embodiment of the invention, the at least one force-exerting element comprises a contact surface on the lid with which the aroma container is moved from the non-activated position to the activated position when the lid is rotated when the lid is unscrewed Position is rotatable. In other words, the rotational movement of the lid when unscrewing is used to rotate the aroma container from the non-activated position into the activated position. This operating principle can be used in the same way to rotate the aroma container from the activated position to the non-activated position when the lid is screwed on, also with the aid of a contact surface on the lid.

According to an alternative embodiment of the invention, the side wall of the aroma container comprises, at least in sections, a projection which extends outward. The at least one force-exerting element comprises an engagement element on the lid, preferably a hook-shaped element, which is arranged and designed to positively grip the projection while the lid is being removed and to move the aroma container from the non-activated position to the activated position.

For this purpose, a single, circumferential hook-shaped element or several hook-shaped elements can be provided on the lid, which snap into place when the lid is screwed onto the drinking device on the underside of the projection on the side wall of the aroma container and when the lid is removed, the aroma container is either opened or unscrewed pull with you and bring it from the non-activated position to the activated position. At the end of the unscrewing process, the aroma container can hit a stop element in the activated position, so that in the last section of unscrewing the lid, the hook-shaped elements deform elastically and again release the projection on the side wall of the aroma container so that the lid can be removed.

According to an alternative embodiment of the invention, the force-exerting element comprises an elastic prestressing element which is arranged between the aroma container and the head part of the drinking device and which prestresses the aroma container into the activated position when the lid is removed.

The elastic pretensioning element can be a part which is formed in one piece with the head part of the drinking device, or is provided as a separate element. In this solution, too, when the lid is removed, the aroma container is moved from the non-activated position to the activated position without any further action on the part of the user.

Ways of Carrying Out the Invention

The invention is explained below purely by way of example with reference to the embodiments shown in the figures. Terms such as top, bottom and side are used as if the aroma container were, for example, after 1 lie with its lower wall on a horizontal, flat surface.

An aroma container 10 according to a first embodiment is in the 1 until 4th shown. The aroma container 10 has an upper wall 12th , a lower wall 14th , an inner side wall 16 as well as an outer side wall 18th on. As in particular in the sectional views 3 and 4th shown enclose the top wall 12th , lower wall 14th , inner side wall 16 as well as outer side wall 18th an aroma chamber 40 .

The top wall 12th is preferably at least partially flat, so that a label on the outside of the top wall 12th is attachable.

The aroma container 10 after 1 is substantially annular with an annular outer side wall 18th and an inner side wall 16 that deviates from a circular shape. In other words, that of the inner side wall 16 enclosed space has a cross-sectional area that is not circular.

In the specific example, as is best shown in the illustration 2 can be seen, the inner side wall 16 with a flat 26th provided and otherwise has approximately a teardrop shape with a substantially tapering end 28 . How out 2 As can be seen, the geometry shown allows the inner side wall 16 a clear positioning of the aroma container on a drinking device, not shown. The aroma container 10 be placed on a correspondingly shaped element of the drinking device, the outer contour of which follows the geometry of the inner side wall to such an extent that the aroma container is only in a single angular position, ie in relation to a rotation in the plane of the drawing 2 , can be placed on the drinking device.

The geometry of the inner sidewall 16 is selected in such a way that the deviation of the inner contour from a circular ring shape is only slight. The ratio between the largest clear dimension Lmax in the cross-sectional area of the through the inner side wall 16 enclosed space in relation to the smallest dimension L _min moves in the range between 1.05 and 1.15 and is preferably about 1.1.

The flattening 26th serves to open the air outlet opening 24 to be able to seal on a suitably designed geometry of the drinking device when the aroma container is pushed on. The provision of a flat partial surface is suitable for this 26th in the area of the air outlet opening 24 better than a rounded surface.

The air outlet opening 24 is in the seam area between an upper shell 20th and a lower shell 22nd intended. This has the advantage that the aroma container can be easily manufactured, since a separate slide does not have to be provided for injection molding, but rather the upper shell 20th and lower shell 22nd jointly the air outlet opening 24 form.

In the area between the upper shell 20th and lower shell 22nd is a shadow gap 30th provided that fulfills various tasks. On the one hand, the provision of a shadow gap between the upper shell 20th and lower shell 22nd prevent material escaping when the upper shell is welded to the lower shell from impairing the visual appearance of the aroma container. In addition, rounded edges can be realized by providing the shadow gap. Another advantage of providing the shadow gap 30th is that the user can be given visually feedback about the operating position of the aroma container by being able to move it in a vertical direction relative to the drinking device and thereby creating a shadow gap for the user in a vertically downwardly displaced arrangement of the aroma container is no longer visible.

The contour of the inner side wall 16 is vertical, ie the space enclosed by the inner side wall has a constant cross-sectional dimension over the height of the aroma container. This enables the aroma container to be displaced vertically relative to an element of a drinking device which extends through the space enclosed by the inner side wall and rests against the inner side wall. The provision of an inner side wall with a vertical extension is advantageous in all embodiments of the invention.

The air inlet opening 48 is in the 4th and is located in the lower wall 14th of the aroma container. The air inlet opening is preferably located 48 thereby in the lower wall 14th in the area of the tapering end 28 and thus diametrically opposite to the air outlet opening 24 . As a result, the air stream flowing through the aroma container has to cover the longest possible distance and in this way can be enriched with aroma substance in a particularly effective manner.

As in the sectional views 3 and 4th is shown is located inside the aroma container 10 the aroma chamber 40 . It is also in the aroma chamber 40 a carrier substance 42 used, which carries the aroma substance. The carrier substance is, as in 2 is shown, U-shaped, that is, not completely circumferential, which means that the carrier substance is mechanically inserted into the lower shell during the production process 22nd of the aroma container before placing the upper bowl 20th makes it easier. The U-shaped geometry of the carrier substance also enables better aroma development, since in the exemplary embodiment according to 1 until 4th in the area of the tapering end 28 the air first in an air-filled room 44 the aroma chamber 40 occurs and then evenly over the entire height of the carrier substance 42 can enter this and flow through the carrier substance.

As in the 3 and 4th is shown, there is a head space above the carrier substance in which the aroma chamber 40 not with carrier substance 42 is filled. The provision of a headspace also has the function of enabling better enrichment of the air and homogenization of the air with aroma substance.

As in 3 and 4th is the vehicle 42 while doing so in the aroma chamber 40 used that the carrier substance on the side facing the aroma chamber 36 the lower wall 14th rests. The headspace 32 is consequently between the carrier substance 42 and the side facing the aroma chamber 34 the top wall 12th intended. The headspace 32 has a height that is less than 50% of the height of the aroma chamber 42 , ie less than 50% of the distance between the side facing the aroma chamber 34 the top wall 12th as well as the side facing the aroma chamber 36 the lower wall 14th . However, it is preferred that the carrier substance occupies at least 80% of the height of the aroma chamber.

In all of the illustrated embodiments, the carrier substance is a nonwoven material which, at a differential pressure of 100 Pa, has an air permeability L of L ≥ 200 1 / (m ² • s) and preferably between 220 1 / (m ² • s) and 280 1 / (m ² • s ) owns. The fleece preferably consists of 100% polyester. The porosity of the fleece material is between 70% and 93% and preferably between 70% and 80%.

The diameter of the air inlet opening in the lower wall is in the embodiment according to the 1 until 4th at 1 .2mm.

By the upper shell 20th and lower shell 22nd are connected to each other by ultrasonic welding, the upper shell and lower shell are tightly connected all around except in the area of the air outlet opening, so that a potential penetration of air into the aroma container or an undesired escape of aroma substance, for example during storage, can be avoided from the aroma container .

The ones in the 5 until 8th illustrated embodiment of the aroma container 10 differs from the aroma container according to the 1 until 4th only by the fact that on the outer side wall 18th of the aroma container has a protruding area 46 is provided. In the embodiment of 5 and 8th is the above area 46 designed as a circumferential edge, but can also comprise individual, separate subsections in the same way. In the same way is in the embodiment according to 5 and 8th the circumferential edge is level with the upper wall 12th arranged, which is also only an example. It is equally possible to provide the protruding section or sections at any desired position on the side wall. Finally, it should also be clear that the overall geometry of the 5 until 8th Aroma container shown is also to be understood only as an example. The aroma container does not have to have a ring shape. It is only important that the side wall comprises a projection at least in sections. It is preferred here that the projection extends outwards essentially perpendicular to the outer side wall.

In the embodiment according to 5 until 8th shown circumferential edge 46 serves to make the aroma container easier for a user can be grasped. In a special embodiment, which will be explained later, in cooperation with a drinking device, the circumferential edge 46 can also be used to move the aroma container in a convenient manner between an inactivated position and an activated position or to separate it from the drinking device.

The surrounding edge 46 only needs to have a small radial extension in order to make it easier for a user to grasp the aroma container. As a rule, an outward extension of 0.6 mm to 1.5 mm is sufficient to offer the user additional support when gripping and pulling the aroma container upwards. With regard to the vertical height of the circumferential edge, too, it is sufficient if the circumferential edge has a thickness, ie a vertical extension between 2.0 mm and 2.5 mm. In the case of common plastic materials from which the aroma container is preferably made, sufficient stability can be achieved by providing a thickness for the circumferential edge in this area.

In the 9 and 10 is a plan view and a three-dimensional view of a further alternative embodiment of an aroma container according to the invention. The aroma container according to the 9 and 10 is constructed similarly to the aroma container according to the previous embodiments, but has a recessed grip 50 in the area of the side wall 18th . Also the aroma container after the 9 and 10 can be provided with a section-wise or circumferential edge as in the embodiment according to 5 until 8th be provided. The recessed grip 50 serves to ensure that the user can better grip the aroma container when sliding the aroma container onto the head part of an associated drinking device, which simplifies the operation of the aroma container.

In addition to a protruding section such as the circumferential edge shown as an example 46 as well as a recessed grip 50 Other geometries are also conceivable that ensure easier gripping of the aroma container. For example, this can also be done by providing a suitable surface structure of the side wall, such as a textured surface, or the use of coatings, for example with elastomers.

In numerous embodiments, reference is made to an essentially annular geometry of the aroma container with an annular shape on the outside and an approximate teardrop shape on the inside, in order to be able to better point out the specific differences between the individual embodiments. Nevertheless, it should be apparent that the aroma container according to the invention is not restricted to such a geometry. The following is an example of a different geometry 11 and 12th referenced having an aroma container 10 represent, which is designed essentially U-shaped.

The aroma container according to the 11 and 12th again has an upper wall 12th , a lower wall 14th , an inner side wall 16 as well as an outer side wall 18th on. The outer side wall 18th can as in the embodiment of the aroma container according to the 9 and 10 with a concave in the side wall 18th arranged recessed grip 50 be provided. In the same way, the aroma container after the 11 and 12th with a surrounding edge 46 be provided, as based on the embodiments according to 5 until 8th has been described. The air outlet opening 24 is like in 12th is shown, in the middle of the U-shaped geometry of the aroma container in the area of a flat 26th intended.

The aroma container differs from the previous embodiments 10 after 11 and 12th with two air inlets 48 provided, each in the area of the free ends 52 of the U-shaped profile and ensure that the aroma substance in the carrier substance of the aroma chamber is removed from the area of both free ends 52 is taken up by the air flow flowing through.

The one in the 13th and 14th The aroma container shown has a positioning attachment 54 on, which is in the area of the inner side wall 16 near the lower wall 14th as well as the air outlet opening 24 is located. The positioning approach 54 extends from the inner side wall 16 into the space enclosed by the inner side wall and has cross-sectional dimensions which are the same in the vertical direction of the aroma container, ie in a direction perpendicular to the plane of the drawing 14th .

The positioning approach 54 serves to hold the aroma container 10 to position exactly on the head part of an associated drinking device and to represent a guide along which the aroma container in the vertical direction, ie in a direction perpendicular to the plane of the drawing 14th can be moved relative to the drinking device.

The provision of a positioning approach 54 whose geometry is in 13th is shown only by way of example, also has the advantage of being able to realize a clear positioning between the aroma container and the drinking device, if, unlike in the example shown, after 13th and 14th , the geometry of the aroma container without positioning approach no clear relative positioning should allow between the aroma container and a drinking device.

Furthermore, it is according to the embodiment of the aroma container 13th and 14th possible to cooperate with a drinking device, which can be firmly coupled to the aroma container above all in the area of the positioning attachment, but no contact with the inner side wall in other areas of the inner side wall 16 of the aroma container, whereby the friction between the aroma container and the head part of a drinking device, which can be reduced by the from the inner side wall 16 enclosed space extends. The smaller the contact area between the aroma container and the drinking device, the lower the frictional forces that have to be overcome when the aroma container is attached to the drinking device and when the aroma container is displaced in the vertical direction relative to the drinking device.

In the 15th and 16 an embodiment of the aroma container according to the invention is shown, in which from the inner side wall 16 Sliding ribs 56 extend into the space enclosed by the inner side wall. The sliding ribs extend in the vertical direction and have a rounded side wall from the inner side 16 away-pointing contour, so that in the area of the sliding ribs 56 essentially just a line contact between the aroma container 10 and the head portion of a drinking device can be made extending through the from the inner side wall 16 of the aroma container extends enclosed space.

The sliding ribs 56 , which extend in the vertical direction of the aroma container, additionally serve to guide the aroma container and to enable the aroma container to be pulled straight off a drinking device. In the following embodiments, design variants are shown in which an aroma container can be moved between an activated position and a non-activated position.

In the embodiment according to 17th until 20th the aroma container is moved between the activated and inactivated positions by the upper bowl 20th and the lower shell 22nd of the aroma container 10 are movable relative to each other. For this purpose, as shown in the sectional views in 18th and 20th it can be seen the upper shell 20th and the lower shell 22nd displaceable against each other in the vertical direction.

The aroma container can interact with a drinking device in such a way that the drinking device extends with its head part through the inner side wall 16 Enclosed space moved through. The lower wall 14th , in which the air inlet opening 48 is in the non-activated state, which is shown in 18th is shown, rest on the head part of the drinking device so that the air inlet opening 48 is sealed. In addition, the air outlet opening is also in the non-activated state 24 locked. If the aroma container is now pulled vertically upwards by either a user or, as will be explained later, the lid of the drinking device under the circumferential edge 46 grips and pulls the aroma container upwards in the direction of arrow A, the upper bowls, which can be moved relative to one another, become 20th and lower shell 22nd pulled apart, making the passage 58 in the area of the air outlet opening 24 forms (see 20th ). In this way, when the aroma container is moved vertically in the direction of arrow A, both the air inlet opening 48 as well as the air outlet opening 24 opened and the aroma container thus brought into an operational, activated position.

The embodiment according to 21 and 22nd shows an alternative design of a flavor container 10 that when a lid is operated 70 the drinking device is movable between the activated and the non-activated position. This is done by the lid 70 in the direction of rotation B either unscrewed from the drinking device or screwed onto it. The lid is designed in such a way that it can be moved freely and independently of the aroma container, but in the last section of the complete screwing onto the drinking device by means of a driving surface 72 comes into engagement with an upper edge area 74 of the aroma container. When the lid is screwed onto the drinking device, the aroma container is moved clockwise so that the aroma container is in a non-activated state in which the air outlet opening is no longer aligned with a corresponding inlet opening in the transport channel for drinking liquid and therefore no aromatic air from the Aroma container can be dispensed. The rotation of the aroma container can also be carried out manually by the user in the same way.

In the same way, when unscrewing the lid from the drinking device according to FIG 21 the take-away area 76 of the lid with the upper edge area 78 of the aroma container 10 come into engagement and the aroma container according to the direction of arrow B in 21 Move with it until the aroma container is in an activated position and the lid moves upwards in the plane of the drawing 21 with its take-away area 76 is no longer in engagement with the top edge area 78 so that the aroma container thus remains in its activated position during the further rotation of the lid.

In the 23 shows an alternative way in which the aroma container 10 in cooperation with a drinking device 60 can be automatically brought into an activated position when, by opening a lid, there is no longer any vertical pressure from above on the aroma container 10 works. This is in the area of the headboard 80 the drinking device an elastic element, in the present case a helical spring 82 , provided that the aroma container 10 biases vertically upwards. In the representation after 23 the aroma container is not in the activated position, but when the aroma container is placed on the head part 80 the drinking device shown so the coil spring 82 is visible. In operation and in particular when moving the aroma container between a non-activated position and an activated position, it is sufficient that the helical spring 82 the aroma container only moves a short distance upwards where the aroma container against a stop on that part of the head part 80 which pushes through the inner side wall 16 formed space extends. In this way, when the cover is unscrewed, the elastic bias of the helical spring 82 the aroma container moves a defined distance upwards against a stop, where it is in the activated position. In the same way, when the lid is opened, pressure is applied to the top wall 12th of the aroma container 10 exercised and this shifted in the vertical direction downwards into the non-activated position.

The embodiment according to 24 until 26th differs from the one after 23 only by the fact that instead of the coil spring 82 a spring ring 84 is provided. The spring washer has opposite the helical spring 82 according to the embodiment according to 23 the advantage that it is easier to clean.

The spring ring can be provided as a separate component that is inserted into a recess in the head part 80 the drinking device 60 inserted and the aroma container 10 moves vertically upwards from the non-activated position to the activated position as soon as the lid (in 24 not shown) the drinking device is removed and no more pressure on the upper wall 12th of the aroma container. An exemplary form of the spring ring 24 is in the 25th and 26th shown, from which it can be seen that the spring ring is only an annular plate with a curved, elastically deformable middle part 85 that can be easily cleaned by a user.

In the 27 until 30th are the lid 70 and its interaction with an aroma container 10 according to the embodiment of 5 until 8th shown, which allows an automatic movement of the aroma container between the non-activated position and the activated position. The lid 70 the drinking device is provided with at least one engagement hook, in the exemplary embodiment according to the 27 until 30th with three hooks 86 provided that, as best seen from the illustration of the 28 can be seen evenly on the circumference of an inner surface of the lid 70 are distributed. From the sectional view in 29 is the geometry of an engagement hook 86 recognizable in the cut. The engagement hooks extend from the stop surface 88 down in the lid. The stop surface 88 has the function of the upper wall 12th of the aroma container 10 to position. The aroma container has a surrounding rim 46 provided, as in 30th is shown, the engagement hook 86 can grip positively. The aroma container 10 is positioned on the head part of the drinking device exactly in relation to the angle, so that the aroma container does not rotate when the lid is rotated, but the engagement hooks 86 when the lid is rotated around the circumferential edge 46 be moved around and the aroma container when unscrewing the lid 10 with pull up.

When unscrewing the lid, the aroma container is pulled up until it hits a stop. As soon as the aroma container has been pulled up into its activated position, ie its operating position, and hits the stop on the mouthpiece of the drinking device (not shown), the engagement hooks deform when the lid moves further vertically 70 up and come out of engagement with the circumferential edge 46 of the aroma container.

Used after using the drinking device while the aroma container is in use 10 is in the pulled up, activated position, the lid is closed again, so the engagement hooks snap 86 over the surrounding edge 46 of the aroma container. The top wall 12th of the lid 70 then stands against the stop surface 88 of the lid 70 so that with a further vertical downward movement of the lid, for example while the lid is screwed onto a thread on the head part of the drinking device, the aroma container is pressed vertically downwards until the aroma container is in the non-activated position in which the The outlet opening is no longer in flow connection with a corresponding inlet opening in the transport channel for drinking liquid and the air inlet opening arranged on the underside of the aroma container 48 is pressed against a sealing surface on the head part of the drinking device.

The user no longer has to use the aroma container in this embodiment either Move back and forth between the non-activated and the activated position, as this takes place automatically when the cover is unscrewed and unscrewed. If, however, the user would like to drink non-flavored drinking liquid, there is of course the possibility of manually pressing the aroma container vertically downwards into the non-activated position before drinking.

In addition to the variants described above, with the aid of which the aroma container can be automatically moved between the activated and the non-activated position, other solutions not described in detail herein are also conceivable. The aroma container can be pulled up by magnetically coupling the aroma container to the lid. Instead of a screw connection, a bayonet connection can also be provided between the lid and the drinking container in the same way.

It is also possible to provide a hinged lid, either with or without a spring element, which when opening either releases the aroma container so that it can be moved into the activated position by a spring element, or with the help of ramp-shaped inclined surfaces on the lid when opening and closing the Lid automatically rotates the aroma container slightly to move it between the activated position and the non-activated position.

Finally, it is also possible to design the aroma container in such a way that it can automatically be moved from a non-activated to an activated position when a negative pressure is applied. In this solution, the moving part in the aroma container is a non-return valve which opens automatically in the event of a negative pressure when using the drinking device and releases the air outlet opening of the aroma container.

All the solutions described above have in common that the aroma container is designed in such a way that the Reynolds number R _e in the air inlet area is greater than 2000, the Reynolds number being defined as Re = (w • d) / υ, with the kinematic viscosity of air υ [ m ² / s], the diameter d [m] of the air inlet opening and the flow velocity w [m / s] when flowing into the aroma container with an averaged volume flow between 250 ml / min and 600 ml / min. The geometry of the aroma chamber is preferably designed so that with this volume flow of air flowing through to the aroma container, a turbulent air flow prevails in the entire aroma container, the local Reynolds number, which characterizes the local flow state at a certain point in the aroma container, below the air inlet opening instead of the diameter d With the aid of the largest free flow cross-section in each case, is formed in the local area of the aroma container.

The embodiments described above describe individual advantageous configurations of the aroma container according to the invention, which can be combined with one another to the extent that it makes sense, and can also be combined with one another in further embodiments that are not described in detail.
