Description

Field of invention The invention relates to a drinking device for open drinking vessels, in particular for cups and mugs such as tea and coffee cups and / or tea and coffee mugs. State of the art Conventional drinking devices, such as those used as attachments for beverage cans, plastic cups, or drinking glasses, are well known to experts. These devices are intended to improve the feel of the drink when it comes into contact with the lips and generally serve as a hygienic mouthguard. Such devices are known, for example, from EP 4 032 439 A1. That document discloses a drinking attachment for a drinking glass and / or a drinking cup, which has a spout for pouring liquid and a fitting for attaching to a drinking glass, wherein the fitting is designed to clamp a portion of the vessel wall of a drinking glass and / or a drinking cup in a sealable manner, and wherein the drinking attachment is designed in its material and shape such that it can be attached to a drinking glass and / or a drinking cup with different diameters and / or different vessel wall thicknesses. The attachment area has a radially inner and a radially outer clamping arm, between which the receiving space is formed. This space allows a rim area of ​​a drinking glass and / or cup to be detachably clamped into the receiving space. Advantageously, the at least one clamping arm has at least one sealing lip for contact with the wall of a drinking glass and / or cup. This sealing lip allows the drinking attachment to seal tightly against the drinking glass and / or cup without any liquid escaping. Preferably, the sealing lip is arranged on the at least one clamping arm in such a way as to prevent liquid from entering the receiving space. This ensures a secure fit of the drinking attachment to the drinking glass and / or cup. The drinking spout is used as a hygiene measure and to improve the feel on the lips. Advantageously, the spout area and the attachment area are designed to taper radially and axially from the attachment area towards the spout area along a cross-sectional plane, in order to create a comfortable fit against a user's mouth. It may be provided that, in the axial direction, the drinking section projects back or forward from the direction of the attachment area and relative to the side sections, in order to indicate an area for the mouth to rest against the drinking spout. A disadvantage of this drinking spout is that the part of the device required for attachment is very elaborate and complex in its design. The description and drawings indicate that a stable drinking rim is present, with the thickness of the drinking rim being greater than the thickness of the rim of a drinking glass and / or drinking cup. U-shaped profiles with clamping arms, used for sealing, necessitate very similar drinking vessel wall thicknesses, shapes, and diameters due to their design, in order to achieve a functional seal. KR 20 2012 0007295 U discloses an additional drinking cup. The auxiliary cup is attached to the rim of a cup or glass. The end of the auxiliary cup body is rounded, similar to conventional paper cups. The cup attachment is equipped with an elastic element that can expand and contract elastically at the lower part of the second contact element. The elastic element consists of a plurality of cut sections that extend downwards from one side of the lower part of the second contact element; and an elastic link connecting the cut sections. The cut section opens when the elastic link is stretched outwards and is released when the elastic element contracts inwards.Additionally, the stopper projection is formed in an annular shape along the outer surface of the cup mounting part to ensure contact with the entire upper end of the cup. This stopper projection can simultaneously serve as a seal for the mounting part. The auxiliary cup has multiple cut-off sections extending downwards from the lower part of the cup mounting part, forming an annular contact element. These cut sections are shaped to elastically widen in the diameter direction of the cup mounting part. When the cup is mounted to the mounting part, the cut section widens in the diameter direction of the drinking cup due to the extension of the contact element. The contact element serves as a seal as well as enabling the expansion and contraction of the cut-out section. If required, the contact element can also be arranged separately in a ring shape on the cut-out section of the inner wall of the cup mounting part, with the cut-out section being flexibly connected by a separate elastic element made of the same or a similar material as the contact element. The end of the auxiliary cup body comes into direct contact with the user's lips. This end of the auxiliary cup body is rounded, similar to a conventional paper cup. A disadvantage of this device is that the cup mounting part spreads apart during use. This increases the width of the slots in the cut-out section, causing the device to leak during operation. Furthermore, the rounded drinking rim of the device has at least the same thickness as conventional paper cups. DE 10 2023 136 546 A1 describes a protective device for drinking vessels that provides protection for the rim of the drinking vessel, thus preventing direct contact between the mouth and the rim and keeping the rim away from mechanical impacts. The protective body partially or completely encloses the rim of the glass along its circumference, protecting the drinking vessel against mechanical damage from impact with another drinking vessel and / or providing a hygienic contact point on the drinking vessel. Furthermore, impact elements or, for example, thickenings, damping elements, or other protective components can be incorporated into the protective body to prevent mechanical impacts. The protective ring is attached to the edge by means of a clamping connection. The protective ring has an edge section, an outer section, and an inner section within its profile. A clamping slot is formed between the outer and inner sections, which ensures the clamping connection through the elastic behavior of the material. When the glass is upright and mounted, the edge section is oriented upwards, the outer section towards an outside, and the inner section towards an inside. The protective ring forms a contact area against which a person can place their mouth and drink from the glass without having to touch the rim. Additional design elements can, for example, be geometrically adapted to a person's mouth and / or shaped to facilitate the flow of the liquid, such as incorporating a spout-like drinking aid on the protective ring. Furthermore, a disadvantage of this device is that the U-shaped profile with its outer, edge and inner sections requires drinking vessels of very similar dimensions with drinking vessel wall thicknesses, drinking vessel shapes and drinking vessel diameters in order to achieve a functional seal. US Patent 2021 / 0127871 A1 discloses a hygienic rim device. The device comprises a sleeve that protects the user from exposure to potential germs that may be present on the surface of a cup or glass in a public space. A recess forms a slot through which the rim of the drinking vessel can be pressed, so that the sleeve of the rim device forms a protective and hygienic cover over the rim. Preferably, the depth of the recess is a few millimeters. A rim edge forms the connecting upper edge between the two side walls that enclose the rim of the drinking vessel. To provide the user with a smooth surface when drinking from the vessel, the rim is arranged at the same level as the first and second side walls, and the rim is circular. A disadvantage of this device is that the U-shaped profile, with its edge and side walls, requires drinking vessels of very similar dimensions, wall thicknesses, shapes, and diameters to achieve a functional seal. Finally, KR 10-2014-0121283 discloses a detachable beverage guide and spill protection device. The drinking aid and the spill guard (flow restrictor / flow preventer) are detachably connected by a connecting element. The drinking aid is attached to the upper rim of the cup, while the spill guard surrounds the cup wall. The drinking guide and spill guard are connected by this connecting element. However, the connection between the drinking guide and spill guard is not a continuous band, but rather a point connection via opposing parts, similar to an axis. This allows the spill guard to optimally fulfill its function of guiding the water along the side of the cup while simultaneously facilitating attachment and removal. The drinking aid and spill guard are made of rubber. The drinking aid and spill guard direct the water in the direction desired by the user.This detachable drinking aid with a splash guard allows for easy drinking. The splash guard helps direct the flow of water, making it simple to pour coffee from large cups into smaller ones without spills. This makes it suitable for people with disabilities and infants. The purpose of this device is to facilitate pouring contents into another cup without spills and to make drinking easier. Furthermore, pour spouts are known and are generally used in sealable bottles containing liquid. The prior art cited below does not disclose any device that exhibits the novelty of the present invention. However, the following publications are considered: From DE 197 14 734 C1, a pourer for bottle-like containers is known. By relocating the pouring opening from the pouring opening of the bottle-like container forward and widening it, a geometry is created that further encloses the parabolic liquid flow generated during pouring. This creates a controllable pouring parabola. The pourer consists of a hollow body that can be placed on a wine bottle. The hollow body rests with its bearing surface on the edge of the pouring opening of the wine bottle. For sealing, a highly elastic sealing element is inserted between the bearing surface and the edge of the pouring opening. Extending the axial bore upwards, the wall slopes outwards towards the tear-off edge.The inner and outer walls form an acute angle, creating the tear-off edge. The outer wall is designed so that the body's outer diameter decreases downwards. Alternatively, a relief groove undercuts the tear-off edge on the outside. Crucially, a concave undercut is provided directly below the tear-off edge. This undercut is seamlessly integrated into the pourer's outer contour. Eight elastic, spring-loaded tabs are arranged below the contact surface to extend the hollow body downwards. Each tab has a locking lug at its lower edge, which secures the pourer to the rim of the wine bottle's opening. These locking lugs are designed so that, when the pourer is pushed onto the bottle neck, their lower angles force them apart, allowing them to slide over the bottle's thickening and then spring back together below it.The thickness of the tabs above the locking lugs is chosen to generate sufficient spring action to overcome the upward forces acting on the sealing element, thus securely holding the pourer. To remove the pourer, simply pull it upwards off the wine bottle. An upper bevel then forces the tabs apart again, releasing the pourer. Functionally, the lower bevels have a long cut and therefore a shallow angle of approximately 20° to the body axis, while the upper bevel has an angle of approximately 45° to the body axis. The 45° bevel creates a self-locking mechanism that clamps the pourer against the spring-loaded sealing element beneath the thickened section of the wine bottle.The diameter of the axial bore corresponds at most to the clear width of the neck of the wine bottle. A disadvantage of this well-known device is that the construction for the required sealing is very complex. A pouring spout for beverage bottles, particularly wine bottles, is known from DE 88 14 921 U1. The pouring spout is made of soft rubber and has a hollow cylindrical shaft section, on the upper part of which an annular pouring rim is formed, projecting outwards at an angle. This pouring rim has two boundary surfaces, namely a lower boundary surface and an upper boundary surface. These two boundary surfaces meet at an acute angle and form a pointed pouring edge around the circumference of the pouring rim. A preferred pouring angle of the lower boundary surface is in the range of 35° to 45°, at most 60°. The upper boundary surface of the pouring rim has an angle in the range of 15° to 25°. The upper opening of the shaft section is bounded by an annular projection extending inwards at a right angle to the inner wall of the shaft.The upper boundary surface of the pouring rim extends in a straight line from the inner edge of the annular projection to the circumference, i.e., to the tapered pouring edge of the rim. This arrangement of the inwardly projecting annular projection and the straight course of the boundary surface from the inner edge of the annular projection to the circumference of the pouring rim ensures that no liquid gets between the inner wall of the pouring spout and the outer surface of the bottle neck during pouring. This also applies to residual liquid that, after the beverage has been poured, flows back along this upper boundary surface and then directly into the interior of the bottle when the bottle is tilted back to its starting position. The inner diameter of the shaft section directly below the annular projection is 24 mm. This inner diameter is preferably 1–3 mm larger than the inner diameter of the annular projection.The inner diameter of the shaft section widens slightly towards the bottom, with the lower inner diameter being approximately 1 mm larger than the inner diameter immediately below the annular projection. A circumferential, bead-like thickening facilitates the insertion of the spout onto the bottle neck. The widening of the inner diameter at the lower edge of the spout, in the area of ​​the circumferential bead, compared to the inner diameter immediately below the annular projection, also facilitates the insertion of the spout onto the bottle neck. However, it is also possible to choose a smaller overall axial height, e.g., approximately 10 mm, since no additional space is required on the outer surface of the shaft section for additional components, such as a drip tray. The inner diameter of the annular projection is 18–25 mm. The inner diameter of the shaft section immediately below the annular projection is at least 1 mm larger than the inner diameter of the annular projection. The axial height of the annular projection is approximately 1 mm. The axial height of the upper boundary surface of the casting rim is approximately 3 mm. The overall axial height of the pouring spout in the illustrated embodiment is 21 mm. A lower overall height of approximately 10 mm is also possible. The diameter of the circumferential pouring edge is 38 mm. The axial height of the lower boundary surface of the pouring rim is approximately 4 mm. A disadvantage of this known device is that the boundary surface is approximately 4 mm. From this, it can be deduced that the width of the boundary surface is approximately 5 mm. German patent DE 94 08 418 U1 describes a pouring ring for bottles containing liquid or pourable solid laboratory chemicals. The trumpet-shaped body has a sharp edge at the outlet with an acute angle of attack of 0.01° to 60° and an internal groove at the inlet. Tapered sealing lips are attached to the outside, with the diameter increasing towards the inlet. The pouring ring is inserted into a chemical bottle using its sealing lips, without requiring any modifications to standard screw caps or externally threaded bottles. A fundamental problem with the spouts described here as being based on the state of the art is that they cannot be used with drinking vessels such as coffee and / or tea cups, as they are designed for bottles due to their construction. Task Based on the described prior art, the invention aims to create a drinking device that improves the drinking pleasure and taste experience from commercially available drinking vessels, such as tea and coffee cups and / or tea and coffee mugs. Description of the invention This problem is solved according to the invention by the features of the independent claim. Further advantageous embodiments are the subject of the dependent claims. The drinking device according to the invention has significant advantages over the prior art: The invention makes it possible to provide a drinking device in which different drinking sections allow for different drinking experiences. For example, the advantage of a thin rim is the slower, more gradual enjoyment of the drink. Thinner rims encourage you to purse your lips, causing the beverage to reach the tongue more slowly and in smaller sips, thus releasing the aromas more effectively. This allows for a more conscious and complete perception of the taste sensations (sweet, sour, salty, bitter) across the different zones of the tongue. The perception of these tastes is heightened in certain areas: sweetness is more pronounced at the tip, sour and salty flavors are more noticeable along the sides, and bitter flavors are more intense at the back of the tongue. Therefore, when coffee or another beverage flows slowly from front to back of the tongue, we can fully experience the full range of flavors.A thinner rim provides a more pleasant sensation on the tongue and while drinking, unlike the thick rim often found on standard coffee cups. With a thick rim, we open our mouths wider, the drink flows more quickly over the tongue, and consequently, we taste slightly less. Further advantages of the invention include the fact that the properties and benefits of commercially available coffee cups can be utilized when using the drinking device. The robust and generally thick-walled cups can retain heat longer and are less susceptible to damage during handling and storage. To enjoy a good and pleasant drinking experience, you no longer need a small, delicate, fragile cup with a narrow mouth. Moreover, these cups retain very little heat. Furthermore, the drinking device prevents the beverage from running down the sides and outside of the coffee cup, a common problem when drinking from standard coffee cups with thick walls and rounded edges. In addition, the drinking device is easy to clean after use and is inexpensive and simple to manufacture. According to the invention, a drinking device for open drinking vessels has been created which can be detachably attached to differently shaped drinking vessels with differently designed cup mouths. The drinking device consists of a hollow cylindrical base and comprises an outer surface, an inner surface, an upper rim, a lower rim, and drinking sections. The inner surface features drinking section surfaces, a rim surface, and a mounting surface. The drinking section surfaces can also be located on the outer surface. In another design, both the inner and outer surfaces have drinking section surfaces. The upper rim features the drinking rims of the drinking sections and the rim. A drinking section is inserted into the rim, with its beak-like protrusion. The drinking rim at the beak can be very fine and narrow. The rims of the individual drinking sections are shaped differently. The drinking sections replace the cup mouth or cup rim of the drinking vessel, with the cup mouth being the upper opening or the upper rim of a coffee or tea cup. Preferably and advantageously, the drinking device is made of food-grade silicone. Food-grade silicone does not impart any flavor of its own and allows for a more intense taste perception. Food-grade silicone is tasteless, odorless, has a smooth surface, is easy to clean, and does not react with coffee, thus preserving the pure and unadulterated taste of the beverages. Furthermore, food-grade silicone is advantageously flexible, so the drinking device can also be used with drinking vessels where the mouth of the cup is slightly flared. According to a first aspect of the invention, the drinking sections are arranged at the upper edge. The drinking rim of a first drinking section is very narrow and extremely thin, with a thickness of less than one millimeter. However, the drinking rim is not so narrow as to pose a risk of injury, such as cuts. According to this aspect of the invention, one or more further drinking sections can be present. The rim of the second drinking section is narrow and approximately 0.3 to 1 millimeter thick, so that the rim thickness is roughly the same as that of a thin-walled drinking glass, such as a good wine glass. The edges of the rim may be rounded or beveled. The drinking rim of a third drinking section is designed to be slightly wider, with a drinking rim thickness of one to two or three millimeters, so that the drinking section can, for example, have a round drinking rim. A fourth drinking section is designed like a beak-shaped spout. This spout is designed so that the drink can be drawn from the drinking vessel through the spout using the mouth. This drinking section is integrated into the rim. The edge section has the same cross-section as the hollow cylindrical base body and thus stabilizes the outlet channel of the beak-shaped drinking section. The drinking section areas each run from the edge of the installation area towards the respective associated drinking edges. The height of the drinking area, measured from the edge of the contact surface to the drinking rim, is sufficiently high so that the lips do not touch the edge of the contact surface when drinking. The height of the contact surface, measured from the bottom edge to the top edge, is sufficient to attach the drinking device to a drinking vessel. The cross-section of the contact surface can vary in width and height, as long as sufficient clamping force is present to secure the drinking device. If a drip catcher is also attached, the height of the contact surface is adjusted accordingly. These factors determine the required height of the drinking device. The circumference and / or inner diameter of the drinking device is adapted to the sizes of commercially available open drinking vessels. The drinking device is attached to the drinking vessel via its contact surface. The flexible and elastic properties of the silicone allow for a seal between the contact surface and the drinking vessel. Furthermore, the silicone is sufficiently stretchable and therefore suitable for various vessel shapes and diameters. Tapered sections form the transition from the larger cross-section to the smaller cross-sections of the individual drinking sections. These tapered sections can be either gradual or abrupt. The drinking device, which is slightly stretched by hand, is placed over the rim of the vessel on the outer wall of the drinking vessel and secured by the tension of the silicone material. According to an advantageous embodiment of the invention, the drinking device additionally features a drip catcher on the outside, for example at the lower edge. The drip catcher can be designed such that even when the drinking vessel is tilted and a considerable amount of liquid has accumulated, the liquid does not run out of the drip catcher. This can be achieved, for example, by means of a retaining edge extending towards the outside. According to a further advantageous embodiment of the first aspect of the invention, the drinking device has a recess. The recess is located at the lower edge. This recess allows the drinking device to be used even with drinking vessels where the upper part of the handle, which is attached to the vessel, is closer to the mouth of the cup. The drinking device's contact surface is designed such that the remaining contact area above the recess is sufficient to ensure secure attachment and a seal. In one embodiment with a drip catcher, the drip catcher has a recess and a closure at each end to prevent liquid from leaking out. In another embodiment, the drip catcher is positioned above the recess. According to a further advantageous embodiment of the first aspect of the invention, the drinking device is designed so that it can be opened and closed along its circumference. This allows the drinking device to be attached to the drinking vessel between the handle and the cup. This also makes the drinking device suitable for use with drinking vessels where the upper part of the handle is located directly at the cup's mouth. In this embodiment, the drinking device additionally comprises an opening, a closure with brackets, a safety device, a clamping element, and fastening elements. Further details, advantages, developments and features of the invention will become apparent from the following description, drawings and dependent claims. The invention will be explained in more detail below using preferred embodiments.

Description of preferred embodiments. Figure 1, intended as an application illustration, shows in perspective the drinking device 1 attached to the upper part of a drinking vessel 5. The edge 8a of the contact surface 8 is aligned with the height of the vessel rim 5a. Thus, the drinking edges 3, 6, 7 of the drinking section surfaces 3a, 6a, 7a and the drinking section 9 are positioned above the vessel rim 5a of the drinking vessel 5. This ensures a better drinking experience, as the drinking edges 3, 6, 7 and the drinking section 9 of the drinking device 1 do not make contact with the vessel rim 5a. In this application example, the upper part of the handle 14 is located below the installed drinking device 1 and the lower rim 13. In this embodiment, the drinking device 1 can be adjusted and attached to any desired position around the circumference of the vessel rim 5a. The drinking device 1 is shown here without a drip tray. Due to its clamping force, the contact surface 8 rests tightly and securely against the outer wall of the drinking vessel 5. Despite this tight fit, the drinking device 1 can, due to its material properties, be easily clamped over the rim 5a onto the drinking vessel 5 and thus attached and detached. For example, after the user has chosen the drinking section with the drinking section surface 3a and the drinking rim 3, the drink flows over the rim of the vessel 5a onto the drinking section surface 3a to the drinking rim 3 into the mouth and over the tongue. Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 to 11 show a drinking device 1 according to an embodiment, wherein the drinking device 1 consists of a hollow cylindrical base body. The drinking device 1 comprises an outer surface 2, a drinking rim 3, a drinking section surface 3a, a rim section 4, a rim section surface 4a, a drinking rim 6, a drinking section surface 6a, a drinking rim 7, a drinking section surface 7a, a contact surface 8, an edge 8a, a drinking section 9, a taper 10, 10a, 10b, a drip catcher 11, an upper rim 12, and a lower rim 13. The drinking section surface 3a, rim section surface 4a, drinking section surface 6a, drinking section surface 7a, contact surface 8, edge 8a, and the tapers 10, 10a, 10b are arranged on the inner surface of the drinking device 1. The drip catcher 11 is located on the outer surface 2 at the lower rim 13.The drinking section (9) is located at the edge section (4). Figures 3, 6, and 7 show the drinking device 1 according to one embodiment. These examples illustrate the tapered sections. As shown in Figure 3, the tapered sections 10 and 10b can have a smooth transition. In another embodiment, as shown in Figs. 6 and 7, the taper 10a changes abruptly. In this example, this means that up to this transition, the drinking section areas 3a and 6a can be fully utilized within this region of its partial perimeter. The drinking sections shown in Fig. 6 show the drinking section 9 with its beak-shaped outlet channel and the drinking section with the drinking section surface 3a and the drinking rim 3 in full section AA from Fig. 7 . The drinking section surface 3a extends from the edge 8a of the base surface 8 to the drinking rim 3. The cross-section of the hollow cylindrical base body tapers very narrowly, almost sharply, from the inside, starting at edge 8, towards the outside 2 to the drinking rim 3. In Fig. 8, the drinking sections with the drinking section area 6a with the drinking rim 6 and the drinking section area 7a with the drinking rim 7 are shown in full section BB of Fig. 7. The drinking section surface 6a extends from the edge 8a of the base surface 8 to the drinking rim 6. The cross-section of the hollow cylindrical base body tapers from the inside, starting at edge 8, outwards towards the outside 2 towards the drinking rim 6. In this design, the drinking rim 6 has a narrow, rounded edge. The drinking section surface 7a extends from the edge 8a of the base surface 8 to the drinking rim 7. The cross-section of the hollow cylindrical base body tapers from the inside, starting at edge 8, outwards towards the outer surface 2 and the drinking rim 7, so that the wall thickness at the drinking rim 7 corresponds to that of a thin-walled wine glass. The edge of the drinking rim 7 can be rounded or chamfered. Fig. 9 shows an embodiment of the drinking device 1 according to the invention in a simple perspective view. According to this design, the drinking device 1 additionally has the drip catcher 11 on the lower edge 13 of the outer surface 2. Figures 10 and 11 each show a detail in the partial section of further embodiments of a drip catcher 11. According to these embodiments, the drinking device 1 has a drip catcher 11 at its lower edge 13 and on its outer surface 2. The drip catcher 11 is designed so that no liquid runs out of it, even if the drinking vessel 5 is tilted. As can be seen from the figures, the respective wall profile of the drip catcher 11 in these embodiments is, for example, angular or rounded and has a retaining edge 11a or 11b, respectively. Fig. 12 shows another embodiment of the invention. In addition to the features of the first embodiment according to the invention, the drinking device 1 has a recess 16 on its hollow cylindrical base. This embodiment is suitable for drinking vessels that have an upper handle attachment closer to the rim of the vessel. In the illustrated example, a recess 16 is incorporated into the lower rim 13 and into the drip tray 11. The closures 15 ensure that no liquid leaks from the two ends of the drip tray 11. The width and height of the recess 16 are designed so that a handle of a standard drinking vessel fits into the space within the recess 16. The height of the drinking device 1 is chosen such that the remaining surface area of ​​the existing contact surface 8, which extends above the recess 16 and up to the edge 8a, is sufficient for sealing. Furthermore, the cross-section of the contact surface 8 in this area is sufficient to generate enough clamping force for attachment. The drinking device 1, slightly expanded by hand, is placed over the rim 5a of the vessel against the outer wall of the drinking vessel 5 and secured by the clamping force of the drinking device 1.The recess 16 is located above the area of ​​the handle 14 when the drinking device 1 is attached. This embodiment can also advantageously have several recesses 16 in order to install the drinking device 1 in different positions. Figures 13 and 14 show a further embodiment of the invention. The drinking device 1 shown can be opened and closed again. This makes it possible to attach the drinking device 1 to a drinking vessel through the opening of a handle 14. In addition to the features of the first embodiment according to the invention, the drinking device 1 has an opening 22 on its hollow cylindrical base. The width of the opening 22 and the clamping element 19 are designed such that the upper part of a handle from a standard drinking vessel fits into the upper free space of the opening 22. The first end of the drinking device (1) has the holder 17. The clamping element 19 is attached to the holder 17 by means of a fastening element 20. The second end of the drinking device (1) has the holder 18. The holder 18 is designed such that a holding and clamping device such as the clamping element 19 can be detachably attached to it. In this embodiment, the holder 18 has a groove for inserting the clamping element 19. The fastening element 21 is attached to the clamping element 19.The clamping element 19 is inserted along the groove into the holder 18 and the safety device 23 prevents the closure from being opened unintentionally. The profiles of the brackets 17 and 18 have a height that approximately corresponds to the height of the contact surface 8. This directs the necessary tensile force for fastening onto the cross-section of the contact surface 8. Furthermore, the cross-section and profile of the brackets 17 and 18 are designed to withstand the necessary clamping forces. The open drinking device 1 is placed around the outer wall of a drinking vessel 5, with the opening 22 located in the area of ​​the handle 14. To install the drinking device (1), the clamping element 19 is attached to the bracket 18 with the fastening element 21.
