Abstract
Description
The present invention relates to a drinking bottle comprising a container for drinking liquid, a mouthpiece, a drinking liquid transport channel which extends from a mouth end of the mouthpiece into the container, an aroma chamber for receiving an aroma substance, and an aroma transport channel for transporting air enriched with the aroma substance, i.e. aromatized air, wherein the aroma transport channel extends from the aroma chamber to the drinking liquid transport channel or to the mouth end of the mouthpiece.Such a drinking bottle is suitable for so-called retronasal drinking. The principle of retronasal drinking is explained below.During times of increasing interest in conscious and healthy nutrition, as well as for fitness reasons, the beverage industry offers numerous solutions of reduced-calorie or non-calorie beverages. Many customers wish to low-calorie / non-calorie beverages on the one hand, but do not wish to do away with a taste experience. To meet these requirements, the industry offers sugar-reduced beverages or beverages provided with sugar substitutes or sweeteners. However, these materials may have other health or taste disadvantages.As stated in the introduction in EP 3 944 792 A1, water is therefore frequently provided with fruit flavours. Beverages flavoured in this way can, however, contain undesirable substances (such as the aforementioned sweeteners or colorants) and optionally small amounts of sugar.EP 3 944 792 A1 performs the following: "Since the olfactory sensation constitutes a substantial part of the gustritic sensation during consumption of food and beverages, prior drinking systems attempt to influence the odour perceived during drinking. For this purpose, aroma elements are proposed which can be fastened to a drinking vessel close to the drinking opening so that the aroma element is located in the immediate vicinity of the nose of the user who inhales through the nose during drinking and thus absorbs the scent. WO 2019 / 016096 A1 discloses a drinking device for retronasally receiving a aroma substance with an aroma container through which air can flow, which supplies aromatized air to a transport channel for drinking liquid. In this way, the aroma substance is incorporated retronasally. When drinking, the aroma substance reaches the user's mouth together with the drinking liquid and subsequently rises retronasally via the pharynx to the olfactory mucosa, where it is captured by the receptors located there and perceived by the user. In this case, use is made of the fact that there is a close relationship between the odor sense and the taste sense. The user therefore feels as if he were tasting the flavour, although he actually smells it only retronasal."Drinking bottles for so-called retronasal drinking are known from the prior art, such as e.g. from EP 3 944 792 A1. However, these drinking bottles are often complex to handle.The object of the present invention is thus to provide a drinking bottle with which retronasal drinking is made possible in a more user-friendly, more flexible and alternative manner compared to the drinking bottles known from the prior art. Furthermore, the object of the invention is to use the drinking bottle for a user-friendly drinking.This object is achieved with a drinking bottle according to claim 1 and a use of a drinking bottle according to claim 15.The present invention relates first of all to a drinking bottle comprising a container for drinking liquid, a mouthpiece, a drinking liquid transport channel which extends from a mouth end of the mouthpiece into the container, an aroma chamber for receiving an aroma substance, and an aroma transport channel for transporting air enriched with the aroma substance, i.e. aromatized air, wherein the aroma transport channel extends from the aroma chamber to the drinking liquid transport channel or to the mouth end of the mouthpiece.The drinking bottle is characterized by an aroma transport adjusting element which can assume a blocking position in which the transport of aromatized air through the aroma transport channel is prevented, and which can assume an open position in which the transport of aromatized air through the aroma transport channel is made possible. The aroma transport adjusting element can be set by a user, i.e. moved between the blocking position and the opening position. In the respective positions, the aroma transport actuating element can be locked, i.e. fixed, so that a movement of the aroma transport actuating element out of this position (without the user using) is prevented.The container for drinking liquid can be made of plastic or metal. The container can be manufactured from a plurality of material layers, which can each be manufactured from metal or plastic. The container can be rigid, i.e. rigid. However, it can be provided that the container is (at least partially) made of a flexible material.The mouthpiece is provided for the purpose that a user attaches his mouth or his lips to the mouthpiece during drinking. The mouthpiece may be arranged on the container. The mouthpiece can be formed integrally on the container. The mouthpiece can also be arranged on a container lid; in this case, too, it can be a one-piece component of the container lid. The mouthpiece may be made of the same material as the container or the lid. The mouthpiece can be made of plastic, metal, glass or a glass ceramic.The drinking liquid can be, for example, a taste-neutral, drinkable liquid. The drinking liquid can be water, for example. The drinking liquid can contain carbonic acid, but the drinking liquid can likewise also be present without carbonic acid. The drinking liquid can have any temperature as long as the drinking liquid is liquid. For example, the drinking liquid can have a temperature above its freezing point. The drinking liquid can be cooled, for example at a temperature of 0° C. to 15° C., or at a temperature of >15° C. The drinking liquid can also be present hot, for example at a temperature of > 60° C. or at a temperature close to the boiling point of the drinking liquid. The drinking bottle can comprise an insulating material, with which the temperature of the drinking liquid can be kept constant for a certain period of time or the heating or cooling process of which can be at least slowed down. The drinking liquid may comprise ice or other cooling agents. The drinking liquid can have a taste which is enhanced or (specifically) modified by the aroma entering the oral pharyngeal cavity during retronasal drinking.A drinking liquid transport channel can extend at least partially vertically through a container interior of the container. By "vertical extension" it can be meant that the drinking liquid transport channel extends at least in sections perpendicularly or substantially perpendicularly to the drinking bottle base. This can mean that at least a section of the drinking liquid transport channel runs parallel or almost parallel to a drinking bottle longitudinal axis. The drinking liquid transport channel can, however, also extend through the container interior in a course deviating from a vertical course, for example at least in sections at an angle to the longitudinal axis of the drinking bottle (i.e. not parallel). The drinking liquid transport channel can also run helically, spirally or in a zigzag shape. Furthermore, drinking liquid can be transported vertically upward (in the direction of the mouthpiece) from the container bottom. The drinking liquid transport channel has two ends (with openings), one end of the drinking liquid transport channel being arranged at the mouth end of the mouthpiece and one end in the container interior. The drinking liquid transport channel is bounded by a channel wall. The drinking liquid transport channel can have a tube shape, e.g. with a cylindrical or polygonal cross section. The channel wall of the drinking liquid transport channel can be made of plastic, metal or glass.The drinking liquid transport channel can be formed in particular from plastic, glass, metal or another suitable material. The drinking liquid transport channel can be designed in the manner of a straw.The drinking liquid transport channel can be detachably fastened to the drinking bottle, but can nevertheless also be arranged non-detachably (in particular in one piece) on the drinking bottle. A detachable fastening can be advantageous in order to be able to clean the drinking liquid transport channel in a simple manner. Furthermore, the drinking liquid transport channel can be concertina-like or otherwise foldable, so that it can be folded in size. This can be advantageous in particular when removing the drinking liquid transport channel for cleaning. The detachable fastening or the concertina-like or other foldability can also apply only to a section of the drinking liquid transport channel.A flavoring chamber can be understood to mean a chamber or a space in which a flavoring agent is arranged. When air flows through the aroma chamber, the aroma substance can be carried along (dragged along) by the air. The flavoring agent can be incorporated in a carrier material. The support material may be formed from a natural fabric, textile fabric, plastic, metal, ceramic, nonwoven, pulp, cellulose, paper, cardboard, paper-like or other materials. Carrier materials made from such materials can be considered to be particularly durable. It can be provided that the carrier material is reusable, i.e. it can be repeatedly impregnated with flavoring agent. The flavoring agent can be incorporated as a solid, as a liquid, as a gas or molecularly in the carrier material. The carrier material can be impregnated in the flavoring agent. The flavouring or carrier material with flavouring may be arranged in a flavour pad, the flavour pad being accommodated in the flavour chamber. The drinking bottle can have a device with which the aroma pad can be opened by a user.If the drinking liquid transport channel and the aroma transport channel both extend as far as the mouth end of the mouthpiece, this can lead to a particularly intensive taste perception, since aroma and drinking liquid mix only in the oral pharyngeal cavity. The concentration of the aroma can thereby be increased in the aroma-drinking liquid mixture. Furthermore, flavor losses due to such an arrangement of the drinking liquid transport channel and the flavor transport channel can be minimized.The invention further relates to a use of a drinking bottle designed according to the invention for horizontal drinking. Horizontal drinking means that the drinking liquid transport channel and the aroma transport channel are arranged parallel in the region of the mouth end of the mouthpiece of the drinking bottle, and extend horizontally to the mouth of a drinking person. This makes it possible to avoid the drinking person, i.e. a user of the drinking bottle, having to hold the drinking bottle at an uncomfortable angle in order to be able to drink therefrom.Further embodiments and features of the invention are specified in the dependent claims. The embodiments and features specified in the dependent claims will be described below together with further embodiments and features.According to a first embodiment of a drinking bottle according to the invention, it can be provided that in the open position of the aroma transport adjusting element air can flow from the outside of the drinking bottle into the aroma chamber and, starting from the aroma chamber, with entrainment of aroma into the aroma transport channel as far as the drinking liquid transport channel or as far as the mouth end of the mouthpiece.If a flavoring agent is present in the flavoring chamber, air can flow into the flavoring chamber in the open position, and carry along or "carry along" the flavoring agent. When flowing into or through the aroma chamber, the air is thus aromatized or enriched with the aroma substance. Thus, the air enriched with the flavoring agent can be transported via the flavoring transport channel as far as the drinking liquid transport channel or as far as the mouth end of the mouthpiece. In order to generate a flow of air from the outside of the drinking bottles into the aroma chamber, then from the aroma chamber into the aroma transport channel as far as the drinking liquid transport channel or as far as the mouth end of the mouthpiece, a user must generate an air suction (also air draw) or a vacuum with the mouth on the mouthpiece. This can be done by suction at the mouthpiece with the mouth. As a result of the air suction or the generated air flow, molecules or particles of the flavoring agent are distributed in the air and are entrained by the latter as transport medium. If the air enriched with the flavouring agent is intended to flow into the drinking liquid transport channel, a drinking liquid-air-flavouring agent mixture enters the oral pharyngeal cavity of a user from the drinking liquid transport channel. There, the drinking liquid (usually water) is associated with a taste associated with the flavoring substance on the basis of the retronasal perception principle. If the air enriched with the flavoring agent flows as far as the mouth end of the mouthpiece, the drinking liquid from the drinking liquid transport channel and the air enriched with the flavoring agent from the flavoring transport channel each enter the mouth of the user separately and taken by themselves. Only there is optionally mixing of drinking liquid and air enriched with flavouring agent.According to the invention, the container has a container base, a container wall and a container opening opposite the container base and closable by a container lid, wherein the container has a container interior space which is bounded by the container base and the container wall. Via the container opening, when the container lid is not placed, drinking liquid can be introduced into the container. The container cover can be releasably placed on the container and fastened thereto. The container can have a cylindrical basic geometry, for example. In this case, the container wall forms a cylinder jacket, wherein the container bottom is a cylinder bottom. A container having such a shape can be manufactured particularly easily. Furthermore, the container can also have another basic geometry, e.g. polygonal (quadrilateral, pentagonal, hexagonal, etc.). The basic geometry can be cylindrical with dimples / corrugations / ribs, etc. The container may have a variety of designs.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the aroma chamber is formed in the container wall. The aroma chamber can thus be formed directly in the wall material. This allows the aroma chamber to be cleaned directly during cleaning of the container, for example in the dishwasher. From the manufacturing standpoint, the aroma chamber can be formed in the container in a relatively simple manner, for example it can be formed directly during the production of the container, for example during injection molding, or subsequent to the production of the container, for example by mechanical post-processing (for example milling, drilling or punching). The aroma chamber can have the shape of a cylinder, for example, but also have a polygonal contour.According to the invention, the drinking bottle has a plurality of aroma chambers, wherein the plurality of aroma chambers are formed in the container wall. The plurality of aroma chambers may be formed directly in the wall material. The provision of a plurality of aroma chambers enables the arrangement of aroma substances, for example aroma substances of different odours / flavour, in the aroma chambers. Aroma pads can be arranged in the aroma chambers, wherein the aroma pads can relate to different odour / flavour directions. It can be provided to provide a storage compartment for aroma pads on the container, for example below the container base or in the container cover. It can also be provided that-provided a plurality of aroma chambers are provided-aroma substances of different manufacturers or brands are arranged.According to the invention, the plurality of aroma chambers are formed in a wall section of the container wall adjacent to the container opening. In this case, the plurality of aroma chambers can be arranged on a common (identical) vertical level with respect to a vertical axis of the drinking bottle, i.e. the aroma chambers are arranged at the same height. If the container wall is designed, for example, in the form of a cylindrical jacket, the plurality of aroma chambers can be arranged on said common (same vertical level), that is to say at the same height, in a circumferential manner in the wall designed as a cylindrical jacket. In this case, the plurality of aroma chambers can be arranged at a regular, i.e. equal distance from an adjacent aroma chamber. This may mean that the distance between adjacent aroma chambers is constant.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the aroma transport adjusting element is formed by a channel section of the aroma transport channel, wherein the channel section is movable from a first channel section position, in which the channel section does not form part of the aroma transport channel, into a second channel section position, in which the channel section forms part of the aroma transport channel, and vice versa, wherein the channel section in the first channel section position forms the blocking position of the aroma transport adjusting element, and wherein the channel section in the second channel section position forms the opening position of the aroma transport adjusting element. The fact that the channel section in the first channel section position does not form part of the aroma transport channel means that no aromatized air can flow through the aroma transport channel. This is because the channel section (and thus the aroma transport channel) is not connected to the aroma chamber. The channel portion can form a part of the aroma transport channel in the second channel portion position. This means that flavoured air can flow through the flavour transport channel, since the channel section (and thus the flavour transport channel) is connected to the flavour chamber in this position. In this position, flavoured air can flow through the channel portion as well as the flavour transport channel. The channel section, provided it adjoins the aroma chamber, can thus provide a flow connection between the aroma chamber and the remaining aroma transport channel in this position. In the first channel portion position, the channel portion is in a position where the channel portion is not in flow communication with the flavor chamber and the remaining flavor transport channel. For example, the channel section can be twisted relative to the aroma transport channel.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the aroma transport adjusting element is formed by a channel section of the aroma transport channel, wherein the channel section is movable from a first channel section position, in which the channel section is not fluidically connected to the aroma chamber (the flow connection between aroma chamber and channel section is interrupted), into a second channel section position, in which the channel section is fluidically connected to the aroma chamber (the flow connection between aroma chamber and channel section is not interrupted), and vice versa.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the channel section is arranged in or on the container lid, wherein the container lid is rotatably mounted, and wherein by rotating the lid the channel section is movable from the first into the second channel section position and vice versa. With respect to the flow direction of air, the channel section can be formed between the aroma chamber and the mouth end or between the aroma chamber and the drinking liquid transport channel, but in particular directly adjacent to the aroma chamber. In this case, the channel section can extend from the cover outside radially in the direction of the cover center. The channel section thus preferably runs perpendicular to a central lid vertical axis (an imaginary axis which adjoins a container vertical axis in alignment, wherein both axes form a drinking bottle vertical axis, wherein the drinking bottle vertical axis runs centered along the longest extension of the drinking bottle). By rotating the cover, a radially outer opening of the channel section can be brought into register with an aroma chamber or be fluidically connected thereto. If a plurality of aroma chambers are provided, the radially outer opening of the channel section can be brought into register with the respective aroma chambers by rotating the cover or can be connected thereto in terms of flow. The radially outer opening of the channel portion can also be brought into a non-covering position with the aroma chambers by rotating the cover, for example by the radially outer opening of the channel portion lying between the aroma chambers. This would correspond to the first channel section position. In the region of the central vertical axis of the lid, the channel section can bend vertically downwards (i.e. in the direction of the container bottom) and open into a positionally fixed (non-rotatable), for example substantially horizontally extending, further channel section. The further channel section extends as far as the mouth end of the mouthpiece or opens into the liquid transport channel. In the first channel section position as well as in the second channel section position, the cover can be locked. The lid may be rotatably mounted on the container.It can also be provided that the cover is formed in two parts, wherein an outer cover part is formed, for example, in the manner of an annular perforated disk with a central opening, wherein the outer cover part can be arranged fixed in position on an upper edge of the container wall surrounding the container opening. An inner cover member is positioned in the central opening of the outer cover member and is rotatably supported on the outer cover member. The channel section is arranged in or on the inner cover part. The radially outer opening of the channel section is arranged at the level of the aroma chamber. This is because they can only be connected to one another in this way.The pivot bearing can be a slide bearing or roller bearing, in particular a ball bearing. With such a pivot bearing, a simple change of position of the channel section can take place with respect to the first and second channel section positions. This can be done by rotating the cover or the inner cover part. For this purpose, the surface of the cover or of the inner cover part can have one or more profiled surface sections, so that easier handling for a user is made possible and slipping off is avoided.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the wall section is mounted rotatably with respect to the container wall. In this embodiment, the wall section is therefore not fixedly integrated into the container wall or is integrally connected thereto, but rotatably mounted thereon. The wall section can also in this case continue the container wall vertically upwards. In the case of a cylindrical container, the wall section can be regarded as a cylindrical section. The rotatable bearing can be a sliding or rolling bearing arrangement, in particular a ball bearing. It can be provided that the aroma transport adjusting element is formed by the rotatably mounted wall section, wherein the wall section is movable from a first wall section position, in which the aroma chamber is not connected to the aroma transport channel, into a second wall section position, in which the aroma chamber is connected to the aroma transport channel, and vice versa, wherein the wall section in the first wall section position forms the blocking position of the aroma transport adjusting element, and wherein the wall section in the second wall section position forms the opening position of the aroma transport adjusting element. In this embodiment, the aroma transport channel is preferably arranged fixed in position, i.e. non-rotatable. By rotating the wall section, an aroma chamber can be brought into register with the aroma transport channel or can be connected fluidically. If a plurality of aroma chambers are provided, then by rotating the wall section any aroma chamber can be brought into register with the aroma transport channel or can be connected fluidically. If aroma pads with aroma substances of different odor or taste directions are arranged in the individual aroma chambers, the user can easily select a specific odor or taste by rotating the wall section.According to a further embodiment of a drinking bottle according to the invention, it can be provided that a non-return valve is arranged in the aroma transport channel. Such a non-return valve opens during drinking, so that in this case flavoured air can flow through the aroma transport channel in the direction of the mouth end of the mouthpiece or in the direction of the drinking liquid transport channel. When the drinking process is ended, the check valve returns to a closed position and prevents, for example, a desired entry of liquid (e.g. saliva) into the aroma transport channel. The check valve can have, for example, a movably mounted ball as a valve body. During drinking, the ball moves, due to a suction force acting on the ball, into a position in which air can flow past the ball. When the drinking process ends, the ball blocks the air flow in the aroma transport channel. Such a non-return valve can additionally or alternatively also be arranged in the drinking liquid transport channel.According to a further embodiment of a drinking bottle according to the invention, a pressure compensation device provided for pressure compensation in the container interior during drinking can be provided. During drinking, a negative pressure is produced in the container for drinking liquid due to the sucking in of the drinking liquid. The pressure compensation device can counteract the negative pressure during drinking or prevent / reduce the generation of a vacuum. This can make the drinking more comfortable for a user, since he has to use less suction force when sucking in the drinking liquid and air and does not have to "combat" the negative pressure which arises in the container.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the pressure compensation device is a pressure compensation line running from the outside of the drinking bottle into the interior of the container. The pressure compensation conduit may be a channel (e.g., an air channel). The pressure compensation line can be formed in the container wall, preferably in the upper region of the container wall. The pressure compensation line can be formed in the cover. The pressure compensation line can be formed in the region of the mouthpiece (in particular when forming a mouthpiece formed integrally with the container wall or a mouthpiece which can be fastened to the container wall), and thereby run through the container wall and the mouthpiece. The pressure compensation line can be siphon-like, labyrinth-like or zigzag-like in order to prevent or minimize the escape of drinking liquid through the pressure compensation line. The pressure compensation line can be a capillary.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the pressure compensation line has a pressure compensation valve. The pressure compensation valve can open during drinking, while it is closed during a non-taking drinking process. The pressure compensation valve can be designed in such a way that it opens due to the negative pressure produced in the container during drinking and closes when the negative pressure is not present.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the pressure compensation device is formed by a component delimiting the container interior or by a plurality of components delimiting the container interior, which is or are manufactured from a reversibly deformable material. A reversibly deformable material can be brought from a starting position into a deformed position and can return from this deformed position back into the starting position. In the present case, this means that, when drinking, i.e. when negative pressure is generated in the container, the component delimiting the container interior or the components delimiting the container interior is / are preferably deformed in the direction of the container interior. During drinking, the volume of the container interior is thus reduced by deforming the component delimiting the container interior or the components delimiting the container interior. After completion of the drinking process, the component delimiting the container interior or the components delimiting the container interior moves back into its / their starting position, wherein the volume of the container interior is again increased. The deformable material is reversible, i.e. it can be deformed multiple times (without damage). The reversibly deformable material can be an elastic material. The reversibly deformable material can be, in particular, plastic, a textile material, a rubber or rubber-like material, silicone or another suitable material. The reversibly deformable material can be, in particular, a compressible and expandable material.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the component delimiting the container interior is the container base, the container wall, a section of the container base, and / or a section of the container wall. As is evident from the "and / or" linkage, only one of the aforementioned components (e.g. only the container base, only the container wall, only a portion of the container base, or only a portion of the container wall) can form the component delimiting the container interior (made of a reversibly deformable material). However, a plurality of the aforementioned components can also provide the plurality of components delimiting the container interior. It can be provided, for example, that several sections of the container wall and / or of the container bottom are made of a reversibly deformable material. The container cover can also be made of a reversibly deformable material or can have a section of a reversibly deformable material. Thus, the container cover can also additionally or alternatively provide a component of reversibly deformable material delimiting the container interior.According to a further embodiment of a drinking bottle according to the invention, it can be provided that the component delimiting the container interior is formed by a material layer of the reversibly deformable material adjoining the container bottom and / or the container wall in the container interior. The material layer can be fastened to the container wall, e.g. injection-molded onto the latter by injection molding or vulcanized onto the latter. The component delimiting the container interior can also be an inner chamber or inner container. In the case of the formation of an inner chamber or an inner container, the drinking liquid transport channel preferably extends into the inner chamber or the inner container. The inner chamber or the inner container made of reversibly deformable material can be connected firmly, i.e. firmly bonded to the container (e.g. injection-molded or vulcanized), but can also be connected detachably to the latter (e.g. by positive locking, frictional locking or suitable fastening means). A detachable connection can have advantages, since the inner chamber or the inner container can thus be cleaned or exchanged independently of the container.In a further embodiment of a drinking bottle according to the invention, it can be provided that a section of the aroma transport channel adjoining the aroma chamber, which section can in particular be a section of the channel section, is designed to taper conically starting from the aroma chamber, e.g. in the manner of a funnel. This can be advantageous for the most efficient possible flow of aroma flowing from the aroma chamber into the aroma transport channel. Adjacent to the aroma chamber, the subsection can have the same or approximately the same diameter as the aroma chamber. Starting from the aroma chamber, the diameter of the subsection decreases due to its conically tapering shape.Further embodiments of the invention are specified in the figures and in the following description of the figures.

It should be expressly mentioned that the features described in the figures and in the description of the figures here can be developments of the features and combinations of features specified in the claims.According to the invention, the drinking bottle 1 comprises a container 2 for drinking liquid, a mouthpiece 3, a drinking liquid transport channel 4 which extends from a mouth end 5 of the mouthpiece 3 as far as into the container 2, an aroma chamber 6 for receiving an aroma substance, and an aroma transport channel 7 for transporting air enriched with the aroma substance, i.e. aromatized air, wherein the aroma transport channel 7 extends from the aroma chamber 6 as far as the drinking liquid transport channel 4 (cf. the exemplary embodiment according to FIGS. 13, 14, 15, 16 to 17) or as far as the mouth end 5 of the mouthpiece 3 (cf. the exemplary embodiment according to FIGS. 1, 2, 3, 4, 5, 6, 7, FIGS. 8, 9, 10, 11 to 12 ) extend. The drinking bottle 1 has an aroma transport adjusting element which can assume a blocking position in which transport of aromatized air through the aroma transport channel 7 is prevented, and which can assume an open position in which transport of aromatized air through the aroma transport channel 7 is made possible.In the open position of the aroma transport adjusting element, air can flow from the outside 8 of the drinking bottle (i.e. from the outside environment of the drinking bottle 1) into the aroma chamber 6 and, starting from the aroma chamber 6, with entrainment of aroma into the aroma transport channel 7 as far as the drinking liquid transport channel 4 or as far as the mouth end 5 of the mouthpiece 3. For this purpose, the aroma chamber 6 has an inlet opening for air facing the outside 8 of the drinking bottle. In addition, the aroma chamber 6 has an air outlet opening facing the aroma transport channel 7.In all the exemplary embodiments shown, the container 2 has a container base 9, a container wall 10 and a container opening 12 which is situated opposite the container base 9 and can be closed by a container lid 11, wherein the container 2 has a container interior 13 which is bounded by the container base 9 and the container wall 10. The exemplary embodiments shown show a drinking bottle 1 with a container 2 in cylindrical form. The container wall 10 is thus a container jacket. A drinking liquid is introduced into the container interior 13 via the container opening 12 or emptied therefrom.FIGS. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 to 12 relate to a construction or an exemplary embodiment of a drinking bottle 1 in which a plurality of aroma chambers 6 are formed directly in a container wall 10. The aroma chambers 6 are fixed in position, i.e. cannot be moved, in this exemplary embodiment. The aroma chambers 6 are distributed over the periphery of the container wall 10 (cf. FIGS. 1 and 2 ). The aroma chambers 6 are formed in a wall section 14 of the container wall 10 adjacent to the container opening 12.The aforementioned aroma transport positioning element is formed in this exemplary embodiment by a channel section 15 of the aroma transport channel 7, wherein the channel section 15 is movable from a first channel section position A (FIG. 4 top), in which the channel section 15 does not form part of the aroma transport channel 7 (there is no aroma transport channel 7 since the connection to the aroma chamber 6 is interrupted), into a second channel section position B (FIG. 4 bottom), in which the channel section 15 forms part of the aroma transport channel 7 (the aroma chamber 6 is connected to the aroma transport channel 7), and vice versa, wherein the channel section 15 forms the blocking position of the aroma transport positioning element in the first channel section position A, and wherein the channel section 15 in the second channel section position B forms the open position of the aroma transport actuating element.As shown in Figs. 1 and 2, the mouthpiece 3 is arranged on the container wall 10. As can be seen in FIG. 2, the aroma transport channel 7 and the drinking liquid transport channel 4 end at the mouth end 5 of the mouthpiece 3. In the mouthpiece 3, the aroma transport channel 7 thus runs at least in sections parallel to the drinking liquid transport channel 4.FIG. 3 shows the construction of the drinking bottle from the inside. The channel section 15 is arranged in the container lid 11, wherein the container lid 11 is rotatably mounted, and wherein by rotating the container lid 11 the channel section 15 is movable from the first channel section position A into the second channel section position B and vice versa. The rotatable mounting of the container cover is realized in a ball bearing 22. The container cover 11 is formed in two parts, wherein an outer cover part 23 is formed in the manner of an annular perforated disk with a central opening 24, wherein the outer cover part 23 can be arranged in a positionally fixed manner on an upper edge 25 (cf. FIG. 7 ) of the container wall 10 surrounding the container opening 12. An inner cover part 26 is positioned in the central opening 24 of the outer cover part 23 and is rotatably supported on the outer cover part 23. The channel section 15 is arranged or formed in the inner cover part 26. The course of the channel section 15 is shown in FIG. 3. The radially outer opening 27 of the channel section 15 is arranged at the level of the aroma chamber 6.With respect to a flow direction of air running from the aroma chamber 6 in the direction of the mouth end 5 of the mouthpiece 3, the channel section 15 is formed between the aroma chamber 6 and the mouth end 5. The channel section 15 extends from the cover outside radially in the direction of the cover center. The channel section 15 extends perpendicular to a central lid vertical axis DA (an imaginary axis which adjoins a container vertical axis TA in alignment, wherein both axes DA and TA form a drinking bottle vertical axis, wherein the drinking bottle vertical axis extends centered along the longest extension of the drinking bottle 1). By rotating the inner cover part 26, the radially outer opening 27 of the channel section 15 is brought into register with the aroma chamber 6 or is connected thereto in terms of flow. If a plurality of aroma chambers 6 are provided, the radially outer opening 27 of the channel section 15 can be brought into alignment with the respective aroma chambers 6 by rotating the inner cover part 26 or can be connected thereto in terms of flow. The radially outer opening 27 of the channel portion 15 can also be brought into a non-covering position with the aroma chambers 6 by rotating the inner cover part 26, for example by positioning the radially outer opening 27 of the channel portion 15 between two aroma chambers 6. This would correspond to the first channel section position A. In the region of the central vertical axis DA of the cover, the channel section 15 can bend vertically downwards (i.e. in the direction of the container base 9) and open into a further channel section 28 which is fixed in position (non-rotatable), for example running substantially horizontally. The opening region is marked in FIG. 3 with a dashed line 29. The further channel section 28 extends as far as the mouth end 5 of the mouthpiece 3.The drinking bottle 1 also has a pressure compensation device provided for pressure compensation in the container interior 13 during drinking. Variants of such a pressure compensation device are shown in FIGS. 5, 6, 7, 8, 9, 10, 11 to 12 with reference to the first exemplary embodiment of a drinking bottle. These pressure compensation devices can also be transferred to a drinking bottle according to the second exemplary embodiment (FIGS. 13, 14, 15, 16 to 17).The pressure compensation device can be a pressure compensation line 18 running from the outside 8 of the drinking bottle into the container interior 13. As shown in FIGS. 5 and 6, the pressure compensation pipe 18 may be formed in the inner cover part 26. FIG. 7 shows a variant in which the pressure compensation line 18 is formed in the container wall 10 (below the mouthpiece 3). The mouthpiece 3 can be closed with a cap 31, wherein the cap 31 has a mouth opening 32 for covering the pressure compensation line 18.FIGS. 8, 9 to 10 relate to embodiments in which the pressure compensation device is formed by a component delimiting the container interior 13, which component is manufactured from a reversibly deformable material. The mode of operation of such a component has been explained in detail at the beginning. The core function is to be given to a negative pressure which is produced during drinking in the container interior 13 and deformed (to reduce the volume of the container interior 13) and, after the drinking has ended, to move back into the starting position again.In the example according to FIG. 9, the component made of the reversibly deformable material delimiting the container interior 13 is a section 20 of the container wall 10, in the example according to FIG. 10 a section 19 of the container base 9.FIG. 8 shows an example in which the component of the reversibly deformable material delimiting the container interior 13 is formed by a material layer 21 of the reversibly deformable material adjoining the container wall 10 in the container interior 13.As shown in FIGS. 11 and 12, a storage compartment 33 for aroma pads can be provided in the container cover 11, namely in the inner cover part 26, which storage compartment can be closed by a flap 34. The flap 34 can be pivotably mounted.In the exemplary embodiment of FIGS. 13, 14, 15, 16 to 17, the aroma chambers 6 are likewise formed in a wall section 14 of the container wall 10 adjacent to the container opening 12. The wall portion 14 is rotatably supported with respect to the container wall 10. The wall section 14 can be rotated relative to the container wall 10 in the manner of a turret drum. The aroma transport actuating element is formed by the rotatably mounted wall section 14, wherein the wall section 14 is movable from a first wall section position AA (see FIG. 17 above), in which the aroma chamber 6 is not connected to the aroma transport channel 7, into a second wall section position BB, in which the aroma chamber 6 is connected to the aroma transport channel 7, and vice versa, wherein the wall section 14 forms the blocking position of the aroma transport actuating element in the first wall section position AA, and wherein the wall section 14 forms the opening position of the aroma transport actuating element in the second wall section position BB. The wall section 14 together with aroma chambers 6 is shown in FIG. 16 by itself. The placement of the wall section 14 on the container wall 10 is shown in FIG. 15.Regardless of the configuration of the aroma transport adjusting element, a nonreturn valve 16 can be arranged in the aroma transport channel 7 (FIGS. 13, 14 ). The check valve 16 may have a ball 17 as a valve body. The check valve 16 opens during drinking, so that in this case flavoured air can flow through the aroma transport channel 7 in the direction of the mouth end 5 of the mouthpiece 3 (if it is used in a drinking bottle 1 according to the exemplary embodiment of FIGS. 1 to 12 ) or in the direction of the drinking liquid transport channel 4 (if it is used in a drinking bottle 1 according to the exemplary embodiment of FIGS. 13, 14, 15, 16 to 17). When the drinking process is finished, the non-return valve 16 accelerates back into a closed position and prevents, for example, a desired entry of liquid (e.g. saliva) into the aroma transport channel 7.As shown in FIGS. 13 and 14, in this exemplary embodiment the mouthpiece 3 can be fastened to the container cover 11. Only in the mouthpiece 3 does the aroma transport channel 7 open into the drinking liquid transport channel 4. the mouthpiece 3 is arranged in such a way that horizontal drinking can be ensured. Aroma transport channel 7 and drinking liquid transport channel 4 end parallel at the mouth end 5 of the mouthpiece 3 and are aligned horizontally to the mouth of a user during drinking. The aroma transport channel 7 and the drinking liquid transport channel 4 are arranged fixed in position in this example. Only the wall portion 14 is movably disposed.In an alternative embodiment, in the case of a drinking bottle 1 according to the first embodiment, a subsection 40 of the aroma transport channel 7 adjoining the aroma chamber 6, which subsection is in particular a subsection 40 of the channel section 15, is formed such that it tapers conically starting from the aroma chamber 6, for example in the manner of a funnel. This is illustrated in Figure 18.List of reference characters1 Drinking bottle 2 Container 3 Mouthpiece 4 Drinking liquid transport channel 5 Mouth end 6 Aroma chamber 7 Aroma transport channel 8 Drinking bottle outer 9 Container base 10 Container wall 11 Container lid 12 Container opening 13 Container inner space 14 Wall section 15 Channel section 16 Non-return valve 17 Ball 18 Pressure compensation line 19 Section (container base) 20 Section (container wall) 21 Section (material layer) 22 Ball bearing 23 Outer lid part 24 Central opening 25 Edge 26 Inner lid part 27 Radially outer opening 28 Further channel section 29 Dashed line 30 Cross web 31 Cap 32 Mouth opening 33 Storage compartment 34 Flap 40 Subsection A First channel section position B Second channel section position AA First wall section position when this occurs?
