Definitions

  • the present invention relates to a flavoring reservoir for storing aromatics and for releasing the aromatics to a drink system, the flavoring reservoir having a container which encloses a receiving space with a wall, with at least one air inlet opening and at least one air outlet opening being provided in the wall, and the flavoring reservoir further comprising a substrate material arranged in the receiving space, which material is loaded with an aromatic and releases the aromatic to air that flows in through the air inlet opening, flows along past the substrate material and flows out through the air outlet opening.
  • the invention further relates to a drink system with a drink vessel and a flavoring reservoir that is assigned to that vessel.
  • Drink vessels and drink systems are known from the prior art in which the user is given a taste experience by means of so-called retronasal olfaction when drinking a beverage that is in itself tasteless, such as in particular pure drinking water, mineral water or tap water.
  • drink vessels such as drink bottles, are provided with an aroma body, flavoring container or flavoring reservoir from which flavorings are released, then conveyed to the user's pharynx during drinking, where they trigger the taste experience.
  • Such a drink system is available on the market, for example, in the form of the drink system offered by the German company air up GmbH under the air up® brand (cf. www.air-up.com).
  • This drink system consists of a specially shaped drink bottle and interchangeable flavoring reservoirs fitted to the bottle, referred to by the supplier as “pods”, which release a flavor or aroma when the drink system is used so as to trigger a taste experience when drinking water in particular.
  • the manufacturer offers pods with different aromas referred to as “flavors”, for example raspberry, lemon, cherry, cucumber, etc.
  • the flavoring reservoir of the above-mentioned drink system of the air up® brand has an annular shape and is placed in the area of a mouthpiece in the form of a ring around a drinking straw passed through the mouthpiece.
  • the known flavoring reservoir is formed with a continuous receiving space for a substrate loaded with an aromatic.
  • the air inlet opening and air outlet opening are essentially diametrically opposite each other.
  • One problem with this 11855008.1 system is that the substrate is often not formed in precisely the same manner so that it offers a uniform flow resistance everywhere to the air flowing through it. As a result, most of the air passing through the flavoring reservoir tends to flow along that path from the air inlet opening to the air outlet opening which has the lower flow resistance. In any case, the air flows along only one half of the ring.
  • the aromatic In the ring half through which the air flows more strongly, the aromatic is extracted from the substrate to a greater extent, whereas the aromatic is released to a much lesser extent in the substrate located in the other ring half through which the air does not flow, or at any rate hardly flows.
  • the flavoring reservoir then prematurely stops releasing aromatic to the air flowing through it. It is “used up”, even though there is still sufficient aromatic—indeed about as much as there was originally—in around half of the substrate.
  • a further problem with the known flavoring reservoir is that it is formed of a lower shell and a cover which are welded together after the flavoring reservoir has been filled with the aromatic-loaded substrate. In the process heat is introduced into the system, which can affect the sensitive aromatic, significantly reducing its quality.
  • the object of the present invention is to improve these and other disadvantages of the prior art and to create an improved flavoring reservoir.
  • a further object of the invention is to disclose improvements of a drink system with a drink vessel and a flavoring reservoir.
  • this object is first solved by a flavoring reservoir according to claim 1 .
  • a flavoring reservoir according to claim 1 .
  • Other advantageous embodiments of a flavoring reservoir are referred to in claims 2 to 6 .
  • an improved drink system is disclosed in claim 7 .
  • Other advantageous further embodiments of a drink system are described in claims 8 to 15 .
  • a flavoring reservoir for storing aromatics and for releasing the aromatics to a drink system has a container.
  • This container has a wall that encloses a receiving space formed in the container.
  • the wall has provided in it at least one air inlet opening and at least one air outlet opening.
  • the flavoring reservoir further comprises a substrate material arranged in the receiving space and loaded with an aromatic. The substrate material releases the aromatic to air flowing in through the air inlet opening, along the substrate material and out through the air outlet opening.
  • the flavoring reservoir according to the invention is still designed in accordance with the generally known prior art.
  • the flavoring reservoir according to the invention is characterized firstly in that it has an annular shape with the receiving space arranged around a central aperture and enclosed by the wall.
  • the air inlet opening and the air outlet opening are arranged adjacently with respect to one another.
  • a dividing wall completely traversing the receiving space is arranged therein and that the air inlet opening is arranged in a region which adjoins the dividing wall on a first side of the dividing wall and the air outlet opening is arranged in a region which adjoins the dividing wall on a second side of the dividing wall which lies opposite the first side.
  • This design ensures that the air flowing through the flavoring container passes through the whole circumference of the ring and that there is no parallel connection of the two halves of the ring as in known flavoring containers, where air often flows through only one of the two ring halves.
  • the ratio of the flowed-through length to the diagonal of the flowed-through container cross-section is approximately 1:7.8 (based on the mean diameter of the annular flavoring reservoir).
  • this ratio can be significantly increased to 10:1 or more, in particular doubled to approximately 15.7, while in principle maintaining the dimensions of the annular flavoring reservoir. This leads to a noticeably better and more intense olfactory experience.
  • the air outlet opening of the flavoring reservoir according to the invention may be arranged on an inner wall portion of the wall located on the inside and facing the aperture.
  • air loaded with aromatic exiting the flavoring reservoir can be transferred from there to an inlet opening of a drinking straw of a drink system arranged in the aperture.
  • the air outlet opening arranged on the inner wall portion can be a slit-shaped opening longitudinally extending in the circumferential direction of the ring, the width of whose opening changes continuously in a direction transverse to, in particular perpendicular to, the circumferential direction, in particular tapering when viewed in a circumferential direction.
  • this arrangement allows the size of the cross-sectional area of a passage formed by the air outlet opening and an air inlet opening interacting therewith and having a width smaller than the length of the longitudinally extending air outlet opening, to be adjusted by relative displacement, in particular rotation, of the two openings with respect to each other.
  • This makes it possible to dose the amount of air aspirated through this passage per unit of time and thus also the amount of aromatic entrained by the air and hence the intensity of the retronasal olfactory experience perceived as taste, which can be obtained with the flavoring reservoir and a drink system equipped therewith.
  • the air inlet opening can be arranged in particular on a side wall facing outwards and away from the aperture, on an upper ceiling wall or on a lower bottom wall. If the air inlet opening is provided on a lower bottom wall, this can be closed, for example, by shifting the flavoring reservoir used in a drink system downwards against, for example, the material of a mouthpiece of the drink system, so that no aromatic can escape from there in a non-use position.
  • the air inlet opening is arranged in an upper ceiling wall, if a cap of the drink system is suitably designed, this cap or a component thereof can close the air inlet opening when the drink vessel is closed.
  • the container of a flavoring reservoir can generally be formed by a lower shell, which is in particular formed of a single piece, and a cover which is placed on the lower shell.
  • a bottom, side walls of the lower shell connected thereto and the cover may form the wall surrounding the receiving space enclosed between the lower shell and the cover.
  • the cover may be permanently joined to the lower shell by a cold-formed connection, especially by pressing and/or rolling.
  • the flavoring reservoir is formed as a two-piece construction consisting of a lower shell and a cover. The cover is fixed on the lower shell by pressing and/or rolling.
  • this connection which is ultimately a type of clamp connection, is preferably designed in such a way that the consumer cannot open it without tools or force.
  • the advantage of this design over the welded joint known from the prior art is primarily that the volatile aromatics are not adversely affected by waste heat from the welding process.
  • the design proposed according to the invention is also simpler and cheaper to produce.
  • the clamp connection obtained by pressing and/or rolling should be sufficiently vacuum-proof to ensure that there are no flow short circuits that impair the olfactory experience. This criterion can be effectively met if the sealing surfaces are suitably designed.
  • the flavoring reservoir comprises a container with a wall that has an air inlet opening and at least one air outlet opening and encloses a receiving space formed in the container.
  • a substrate material loaded with an aromatic is accommodated in the receiving space.
  • the flavoring reservoir which may in particular be a flavoring reservoir as described above, is connected or connectable to the drink vessel in such a way that, when a person drinks from the drink vessel, air aspirated through the air inlet opening in the wall of the flavoring reservoir and provided with the aromatic stored in the substrate material is guided through the air outlet opening and to the mouth of the drinker.
  • Such a drink system gives the user a taste experience caused by retronasal olfaction when drinking liquids that are tasteless in themselves, such as water in particular.
  • Such a drink system according to the invention can in particular and advantageously have a mouthpiece from which a drinking straw guided into the drink vessel protrudes at the drinking end and which, apart from the opening formed by the drinking straw as well as any air vent present there or formed with the assistance of the mouthpiece to replenish a volume taken from the container during drinking, essentially seals an interior space of the drink vessel.
  • the drinking straw may then have a peripheral wall and an air inlet opening in the peripheral wall, and the flavoring reservoir may be arranged around the drinking straw in such a way that the drinking straw extends through the aperture and the air outlet opening of the flavoring reservoir and the air inlet opening of the drinking straw lie opposite each other such that, when the drinking straw is sucked, air flows through the air inlet opening, through the flavoring reservoir and out from the air outlet opening.
  • the air outlet opening of the flavoring reservoir is located on its inner wall portion facing the aperture.
  • An air vent opening to replenish a volume removed from the container during drinking may be formed on the mouthpiece.
  • an air vent opening can also be implemented elsewhere in the drink system, for example in a wall of the drink vessel with a valve secured against escape of liquid.
  • the flavoring reservoir may be axially displaceable along the drinking straw in order to open and close the passage formed between the air outlet opening and the air inlet opening.
  • a first spring element for example a cup spring, a ring spring, in particular a shaft ring spring or similar, may be provided and arranged so that it pre-tensions the flavoring reservoir in a position in which the passage formed between the air outlet opening and the air inlet opening is opened.
  • the drink vessel of the drink system according to the invention may have a cap for closing the mouthpiece and for covering the drinking end of the drinking straw.
  • This cap can be configured, for example, as a screw cap and have a multi-start screw thread.
  • the multi-start screw thread makes it easier to thread the screw cap.
  • the pitch of the screw thread is sufficiently large that the screw cap closes tightly with a maximum rotation of 360°.
  • the cap may have a bearing portion with which, when closed, it lies against the flavoring reservoir and displaces it if a first spring element as described above is provided, in particular against a spring force of the first spring element, to a closed position in which the passage formed between the air outlet opening and the air inlet opening is closed.
  • a first spring element as described above
  • the flavoring reservoir is sealed off and deactivated, whereas when the cap is removed, the flavoring reservoir can be raised and activated, in particular automatically opened and activated by the spring force of the first spring element.
  • the air inlet opening is arranged at a position of the flavoring reservoir exposed to the cap and that, when the cap is closed, the bearing portion lies against the air inlet opening and seals it.
  • the cap can at the same time perform the function of closing and sealing the flavoring reservoir and prevent the aromatic from escaping.
  • the bearing portion is formed of an elastic material, in particular an EVA-PE copolymer, or is coated with such material, at least in the area in which it lies against the air inlet opening and seals it when the cap is closed.
  • the bearing portion in the cap of a drink system according to the invention by means of which the flavoring reservoir is pressed down into a closed position when the cap is put on and thus displaced, can in particular be a section of a second spring element arranged in the cap.
  • the cap has three functions: It must cover the mouthpiece as such and seal it against accidental escape of liquid.
  • the mouthpiece as in the prior art, is made of a flexible material, in particular of silicone, and, in addition, due to the special design, in the open state leaves a gap from the edge of the drink vessel at least at one point as a passage for inflowing air, i.e. an air vent opening, this mouthpiece must be pressed securely and firmly against the opening edge of the drink vessel, in particular against a sealing surface, by the cap, at any rate in the area in which it is seated on the opening edge of the drink vessel where it forms an air vent opening in the open state.
  • the cap should be screwed on tightly for this purpose.
  • the known cap has two annular shoulders. One shoulder actuates the flavoring reservoir and pushes it down. The second shoulder seals the part of the bottle in which the drink is stored by pressing a silicone insert on the mouthpiece against the body of the bottle.
  • the second spring element provided according to the invention which can be a cup spring, for example, ensures that the contact pressure of the screw cap is not distributed in an uncontrolled manner between the two annular shoulders. Instead, controlled deformability is introduced into the system. This compensates for manufacturing tolerances and creates two defined pressure points that follow one another and signal to the consumer that the overall system is securely closed.
  • the spring force of the second spring element is preferably selected to be greater, in particular significantly greater, than the spring force of the first spring element. This is because the second spring element, which can then also be understood as a closing spring, must overcome the opposing spring force of the first spring element, which can also be understood as an opening spring, in order to press the flavoring reservoir into the closed position against the spring force of the first spring element.
  • the flavoring reservoir is or can be arranged about the drinking straw so as to be rotatable by at least a predefined angular range.
  • This range can be, for example, approximately 90°, but can also assume other values.
  • the flavoring reservoir, as described above has a slit-shaped air outlet opening on the inner wall longitudinally extending in the circumferential direction of the ring, the width of whose opening changes continuously in a direction transverse to, in particular perpendicular to, the circumferential direction, in particular tapering when viewed in the circumferential direction, and if, on the other hand, the air inlet opening is arranged on the drinking straw and is less wide than the longitudinal extent of the slit-shaped air outlet opening, and if the air inlet opening is, for example, of circular shape, it is possible to control the intensity of the olfactory experience.
  • Stops can be provided to limit end positions, for example to limit positions of maximum passage or complete closure, it being possible between these end positions to continuously regulate the quantity of aromatic released by changing the cross-sectional area of the passage formed by the overlap of the air outlet opening and the air inlet opening.
  • the air outlet opening may further have a larger opening area than the air inlet opening, preferably at least 10% larger, in particular approximately 20% larger. This makes it possible to correct positioning errors in the relative arrangement between the elements supporting the air outlet opening and the air inlet opening, such as the inner wall of the flavoring reservoir and the drinking straw, and manufacturing tolerances.

  • This flavoring reservoir 1 is generally of annular shape with a wall 2 and a receiving space 3 enclosed by the wall 2 which is filled with a substrate material loaded with an aromatic, not shown in more detail here.
  • Air L is able to flow into the receiving space 3 of the flavoring reservoir 1 through an air inlet opening 4 .
  • an air outlet opening 5 is arranged through which the air L exits the flavoring reservoir 1 and is further carried to the drink system.
  • the air L is able to flow through the receiving space 3 of the flavoring reservoir 1 along two parallel paths, on the one hand along the path 6 shown on the right in FIG. 1 , and on the other hand along the path 7 shown on the left in FIG. 1 . If the flow resistance which the substrate material in the receiving space 3 presents to the air flow along the two paths 6 , 7 is different, the air will tend to flow along the path 6 with lower flow resistance. Consequently, depletion of the substrate material takes place there, this being done by releasing aromatic into the air L flowing past. On the other hand, hardly any air L flows through the substrate material in the path 7 , so that little aromatic is released from it.
  • FIGS. 2 and 3 Such a flavoring reservoir 10 is shown in FIGS. 2 and 3 .
  • the flavoring reservoir 10 also has a wall 12 and generally has an annular shape with a central aperture 11 bordered by an inner wall portion 18 of the wall 12 .

  • the air outlet opening 115 of the flavoring reservoir 10 is recognizably slit-shaped, longitudinally extending in the circumferential direction of the annular flavoring reservoir 10 .
  • the slit is not of uniform width, but tapers continuously, starting from a large opening cross-section on the right in the Figure to a small opening cross-section shown on the left in the Figure.
  • the flavoring reservoir 10 can be rotated about the drinking straw 22 , as indicated by corresponding double arrows in FIGS. 3 a through c .

  • the flavoring reservoir 10 is arranged around the drinking straw 22 of the drink vessel 30 in the way described above with reference to FIG. 4 , and can be displaced there by rotation in order to adjust the inflowing amount of aromatic as described above. Displacement is also possible in the axial direction of the drinking straw 22 . Such displacement can serve to activate or deactivate the flavoring reservoir 10 .
  • the flavoring reservoir 10 is pressed by a first spring element 25 , which may for example take the form of a shaft ring spring, into an active position shown in the upper Figure, in which the air inlet opening 23 in the drinking straw 22 is level with the air outlet opening 115 in the flavoring reservoir 10 .
  • a vertical stop 26 on the drinking straw 22 ensures that the flavoring reservoir 10 does not become detached from the drinking straw 22 .
  • this vertical stop 26 is overcome in the manner of a latch; also, the flavoring reservoir 10 can be released from the drinking straw 22 by applying a force sufficient to overcome the latching force, which is not applied by the first spring element 25 .
  • a cap 27 for closing the drink vessel 30 can also be seen, which has strip-like press-down structures 28 . When the cap 27 , which may in particular be a screw cap, is placed on the mouthpiece 24 of the drink vessel 30 , these hold-down structures 28 meet the annular flavoring reservoir 10 and press it down against the force of the first spring element 25 into a position as shown in FIG. 5 b .

  • no aromatic can escape from the flavoring reservoir 10 when the drink vessel 30 is closed with the cap 27 .
  • a central stud structure 29 is formed on the cap 27 , which in the closed state (cf. FIG. 5 b ) projects into the drinking straw 22 and closes it in such a way that no drink liquid can escape from the interior of the drink vessel 30 .
  • FIG. 6 shows an alternative embodiment of the drink system according to the invention with an attached cap 27 in the closed position.
  • the difference compared to the embodiment shown in FIG. 5 is primarily that, instead of the fixed and rigid hold-down structure 28 , as shown in the cap 27 according to FIG. 5 , a second spring element 128 is arranged therein and fixed in the cap which presses on the flavoring reservoir 10 with sections, more precisely with inwardly projecting tongues 31 (cf. FIG. 7 ), and presses it down into the closed position.
  • the spring force of the second spring element 128 pressing down the flavoring reservoir 10 is significantly greater than the spring force of the first spring element 25 pressing the flavoring reservoir 10 upwards towards the open position.
  • the flexibility of the second spring element 128 is such that the cap 27 is placed in a specific closed position that securely seals the drink system even in the event of possible dimensional differences due to manufacturing tolerances, for example, with respect to the height of the flavoring reservoir 10 used in the drink system. Such tolerances are compensated by a possible yielding movement of the tongues 31 of the second spring element 128 .
