Description

TECHNICAL FIELD

[0001] The present invention relates to an insulated container for isothermal storage, in particular for isothermal transport of food, which is in particular designed to be able to stand stably upright. The invention also relates to a system comprising the above-mentioned insulated container which is able to stand stably upright and at least one coaster which comprises a metal element or a metal layer which interacts with the insulated container. BACKGROUND

[0002] Insulated containers are mainly used for transporting food, in particular liquid food, in order to be able to consume it at a temperature which is as maintained as possible after leaving home, for example on the way to work or on a journey. Food, drinks or luxury food items which are particularly suitable for transport in an insulated container include, inter alia, soup, hot or cold drinks such as tea, coffee or soft drinks, etc.

[0003] During transport of such an insulated container until the final consumption of the contents, not only heat loss but also unintentional leakage of the contents during transport is to be prevented. Therefore, such an insulated container is usually equipped with a suitable lid. If at least part of the contents is to be accessed during transport, the lid of the insulated container is usually at least partially opened or removed, at which time the insulated container is to be held in the hand, with the risk of at least partial unintentional spillage of the contents.

[0004] PRIOR ART The prior art document DE 102017002311 A1 discloses a glass container in which a metal element is embedded. The glass container comprises a recess in the base, for receiving the metal element, wherein the metal element is bonded to the bottom of the recess in the base by means of a transparent adhesive and is embedded in transparent plastic which fills the remaining area of the recess. The glass container is in particular a drinking cup made of crystal glass, while the metal element is a magnet. In the manufacture of the glass container, the recess is first formed by inserting a piston into the glass melt of the container. Secondly, the metal element is bonded to the bottom of the recess by means of an adhesive. Finally, in a third step, the plastic is filled into the recess by means of a potting process. As mentioned above, the process of manufacturing the above-mentioned container with a metal element bonded to the bottom thereof by means of plastic is correspondingly complex. SUMMARY

[0005] It is therefore an object of the present invention to provide an insulated container for carrying food, which is able to maintain the desired temperature of the food during transport, in particular during transport, and which allows the contents of the insulated container to be consumed conveniently and safely during transport. In this context, it is a further object of the present invention to provide an insulated container which stands stably upright and is slip-resistant, which is particularly suitable for use in a vehicle, and to provide a system for simple and stable positioning of the insulated container.

[0006] The technical solution is achieved by the features contained in the independent claim.

[0007] Preferred embodiments of the application are mentioned in the dependent claims and / or in the following description.

[0008] The application particularly relates to a thermally insulated container for isothermal storage, in particular for isothermal transport of food, comprising a container with a food-receiving chamber and a lid for closing the thermally insulated container. The container comprises a magnet at its bottom, the magnetic properties, in particular its holding or magnetic force, and its dimensions being selected, designed and arranged in accordance with the specific requirements of the thermally insulated container to ensure that the thermally insulated container can be fixed in a predetermined position by the magnet in a stable, slip-resistant and stationary manner. At the predetermined position, a suitable metal element or metal layer is provided which interacts with the magnet.

[0009] The thermally insulated container preferably comprises a magnet which is particularly suitable for carrying and transporting food, including liquid food. Even during transport of the thermally insulated container, in particular in a vehicle, the thermally insulated container can be kept in a stable, slip-resistant and fixed position, even in the open state. This makes it possible to at least conveniently and safely consume part of the contents of the thermally insulated container when carrying and transporting the thermally insulated container.

[0010] The bottom of the thermally insulated container can suitably comprise an annular outer rim, so that the magnet can be arranged and configured such that, when the thermally insulated container is placed on a surface, the annular outer rim of the bottom is in contact with the surface, while the centrally arranged magnet has only a small gap to the surface on which the thermally insulated container is placed. Thus, the magnet can exert its full attractive force on the metal element or metal layer at the location where the thermally insulated container is placed, so that the thermally insulated container is particularly stable and secure in its upright position when placed, even when placed in a vehicle.

[0011] In order to achieve the above-mentioned advantageous arrangement of the magnet in the bottom of the thermally insulated container, the bottom comprises a central region for accommodating the magnet, which is suitably delimited by an inner rim of the bottom. The magnet can be suitably flat-cylindrical and advantageously fits closely to the central region, the magnet being fixed in the central region by the lid. In this way, the magnet is particularly securely accommodated in the central region of the bottom of the thermally insulated container and is protected against contamination and damage, in particular to its surface.

[0012] The inner rim of the central region is suitably lower than the outer rim and is surrounded by the outer rim on which the thermally insulated container is placed in a stable, slip-resistant and fixed manner. Between the inner rim and the outer rim, a groove extends along the inner rim, the outer rim of the lid cooperating with the groove to provide particularly reliable coverage of the central region.

[0013] To achieve the above-mentioned advantageous properties, the dimensions of the central region of the bottom, the lid, the inner rim and the outer rim are chosen and designed in such a way that the outer rim of the thermally insulated container is in contact with the bottom, so that the magnet of the thermally insulated container is properly accommodated and protected in the central region and is kept at a predetermined minimum distance from the surface of the thermally insulated container, which is at most 2 mm, preferably at most 1 mm.

[0014] The container of the thermally insulated container can preferably be made of stainless steel, to provide a particularly stable container, and can be externally lacquered, coated and / or anodized. The lid is also suitably made of stainless steel and is welded to the inner rim of the central region of the bottom. This ensures that the flat cylindrical magnet is particularly firmly fixed in the central region and is reliably protected. To achieve the desired magnetic properties, the magnet is suitably made of a neodymium magnet.

[0015] The receiving chamber of the thermally insulated container is particularly suitable for holding liquid food and beverages. To achieve the desired thermal insulation of the receiving chamber, the container can have a double-walled structure comprising an inner shell and an outer shell, between which a cavity is formed, which can be evacuated. In addition, the inner shell of the container can be provided with a copper coating, so that the radiant heat of the receiving chamber is reflected by the copper coating.

[0016] The central region of the bottom shell of the thermally insulated container, together with the inner rim of the bottom and the lid, jointly form the above-mentioned central region in which the flat cylindrical magnet is stably accommodated and protected.

[0017] When using the above-mentioned thermally insulated container equipped with a magnet, the thermally insulated container can advantageously interact with the above-mentioned suitable metal base. In this case, the thermally insulated container can particularly advantageously interact with a suitable coaster, which comprises a metal layer that interacts with the magnet of the thermally insulated container and is suitably designed as a nanogel adhesive pad with a non-slip, adhesive bottom. Such a coaster has significant advantages, as it allows a favorable, simple and flexible rearrangement of surfaces, such as trays, tables or storage areas, even in environments such as vehicles, and enables a simple, favorable and particularly flexible, reversible and secure positioning of the thermally insulated container.

[0018] The present application also relates to a system comprising a thermally insulated container as described above, which is equipped with a magnet, and a coaster corresponding to the magnet, which comprises a metal layer that interacts with the magnet and is designed as a nanogel adhesive pad with a non-slip, adhesive bottom, so that the coaster can adhere in a non-slip, fixed manner to a predetermined location, thereby interacting with the magnet and allowing the thermally insulated container to be placed in a stable, secure, non-slip and fixed manner on the coaster.

[0019] The system may preferably include a plurality of coasters, configured to prevent the thermal container from slipping in at least one position (preferably multiple positions). These coasters are specifically designed to match the dimensions of the thermal container's base, and in particular, are larger relative to the base. This system allows for particularly simple and flexible operation of the thermal container in many applications, particularly when used as a means of transport and / or in a vehicle.

[0020] Therefore, the thermal insulation container is suitable for a variety of occasions, and is particularly suitable for the safe transportation of food, especially liquid food, such as on the way to get off work, attending events, traveling, camping and other scenarios, wherein the thermal insulation container can particularly be a thermos cup.

[0021] The insulated container and system described above are particularly suitable for use with suitable conveyances and / or any type of vehicle, wherein magnets are used to maintain the insulated container in a non-slip position and interact with suitable metal elements provided on the conveyance or vehicle equipment.

[0022] Obviously, the thermal insulation container according to the present invention has essentially no size restrictions, especially its storage capacity, and thus can be freely designed in terms of size and structure. This also applies to the magnet of the thermal insulation container, which should be appropriately designed and matched to the storage capacity of the thermal insulation container.

[0023] An embodiment of a particularly optimized thermal insulation container, especially when designed as a thermal insulation cup for holding liquid, can preferably adopt a structure that tapers towards the bottom, especially for ease of gripping, wherein the thermal insulation container can also be specially designed to accommodate a liquid volume of 100 ml to 1,500 ml, preferably 250 ml to 500 ml, and particularly preferably about 300 ml to 350 ml.

[0024] In addition, the specific technical features and details of such a thermos container (preferably designed as a thermos cup), in particular its size, the design and arrangement of the magnets and the fixing method, in particular in the central area of ​​the bottom of the thermos cup, wherein the magnets can also be bonded to the central area of ​​the bottom or mechanically clamped or pressed into the central area of ​​the bottom, etc., will be described in detail below, in particular with reference to Fig. 6 .

[0025] As described above, the magnet lid and the central region lid can be welded to the bottom of the insulated container, particularly to its inner rim. The lid can also be secured to the bottom by other means. To ensure the stability and security of the magnet lid, the lid can also be welded to the bottom by other means, such as welding the lid to the bottom, gluing the lid to the bottom and / or the magnet, or securely securing the lid to the bottom using appropriate mechanical means.

[0026] The system as described above, comprising one thermal container and the corresponding coaster, can of course also comprise a plurality of thermal containers, wherein the thermal containers can be designed in different versions, in particular with respect to their dimensions, capacity and magnets. The design of the coaster should be suitable for all thermal containers in the system, in particular with respect to their dimensions and the anti-slip adhesive base, which is designed as a nanogel adhesive pad, thus providing a system in which differently designed, stably upright thermal containers can be placed anti-slip in a predetermined position.

[0029] Fig. 1Four representations of the thermic container 1 according to one embodiment of the present application are shown, namely a side view of the thermic container 1, a view from above on the lid 16 of the thermic container 1, a view after removal of the lid 16 and a view of the bottom 15 of the thermic container 1.

[0030] The thermic container 1 is mainly used for carrying food, in particular those which are mainly in liquid state, in order to be consumed elsewhere after leaving home, for example at work or on a trip, in order to maintain its optimal preservation temperature, wherein in particular the thermic container 1 is a thermic cup 1. The thermic container 1 uses a container 10 made of a suitable stainless steel material, in particular as shown in Fig. 3 and Fig. 4 . In the embodiment shown in Fig. 1 , the container 10 made of stainless steel material is coated on the outside.

[0031] The thermic container 1 comprises a lid 16, by which the thermic container 1 can be closed, and which is designed to be opened only partially, for example for extracting a liquid.

[0032] The bottom 15 of the container 10 comprises an annular outer rim 152, on which the upright thermic container 1 stands. Furthermore, the bottom 15 comprises a cover plate 153, which is also suitably made of stainless steel material and covers the preferably magnetic magnet 2 accommodated in the central region 150 of the bottom 15. In this respect, reference is also made to the following description, in particular to Fig. 2 , Fig. 3 and Fig. 4 .

[0033] The selection, design and arrangement of the magnet 2 are optimized in terms of the magnetic properties of the thermic container 1, in particular its holding or magnetic force and size parameters, in order to ensure that the thermic container 1 can be fixed securely and slip-proof at the predetermined positions P, PI, P2 by the magnet 2. At these predetermined positions, suitable metal elements or metal layers are to be provided in order to interact with the magnet 2.

[0034] The thermic container 1, which is preferably provided with a magnet 2 at the bottom 15, can provide a stable and slip-proof thermic container 1, in particular a thermic cup 1 suitable for various applications, in particular for the safe transport of food, in particular of liquid food, for example on the way to and from work, at events, on trips and camping. The thermic container 1 is therefore particularly suitable for use in vehicles. The magnet 2 can in particular preferably be a neodymium magnet 2.

[0035] Fig. 2 The thermic container 1, which is preferably provided with a magnet 2 at the bottom 15, can provide a stable and slip-proof thermic container 1, in particular a thermic cup 1 suitable for various applications, in particular for the safe transport of food, in particular of liquid food, for example on the way to and from work, at events, on trips and camping. The thermic container 1 is therefore particularly suitable for use in vehicles. The magnet 2 can in particular preferably be a neodymium magnet 2. Fig. 1, an enlarged view of a thermal insulation container 1 is shown, viewed from below, with the cover plate 153 of the bottom 15 removed, along with a magnet 2 according to one embodiment of the present invention. For clarity, the flat cylindrical magnet 2 is shown outside of the central area 150 in which it is housed. To this end, the magnet 2 is preferably designed to correspond in a form-fitting manner to the central area 150, which is delimited by an inner edge 151.

[0036] The inner edge 151 is surrounded by the outer edge 152, and the heat preservation container 1 stands upright on the outer edge 152. The inner edge 151 is relatively low relative to the outer edge 152. There is a groove around the inner edge 151 between the inner edge 151 and the outer edge 152. Fig. 1 The outer edge of the cover 153 shown in FIG. 1 is adapted to fit within the groove. To ensure stable, secure, and protected placement and retention of the magnet 2 within the central region 150, the cover 153 is preferably connected to the inner edge 151 of the central region 150 by welding. The cover 153, like the container 10 and its base 15, is made of stainless steel.

[0037] In the center of the inner central area 150, near the position of the magnet 2, there is a suction port. The suction port is sealed by bonding the material after the insulation container 1 is manufactured, and is used to evacuate the cavity 13 of the container 10 and provide its thermal insulation performance. The details are as follows Fig. 3 and Fig. 4 shown.

[0038] Fig. 3 Shows Fig. 1 1 is a longitudinal sectional view of the container 10 portion of the thermal insulation container 1, which includes a magnet 2 and a cover 153, which are appropriately designed to accommodate the bottom 15 of the thermal insulation container 1 and the various components of the magnet 2. Fig. 4 Shows Fig. 3 The container 10 portion of the thermal insulation container 1 is shown in the state after being assembled as expected.

[0039] The container 10 of the thermal insulation container 1 includes a receiving chamber 14, which is particularly suitable for holding liquid foods and beverages. To achieve good thermal insulation in the receiving chamber 14, the container 10 adopts a double-layer structure, consisting of an inner shell 11 and an outer shell 12. A cavity 13 is formed between the inner shell 11 and the outer shell 12. This cavity 13 can be evacuated, for example, and a getter can be placed therein to substantially maintain the vacuum state within the cavity 13 over the long service life of the thermal insulation container 1.

[0040] As mentioned above, the container 10 of the thermally insulated container 1 is made of stainless steel and is suitably manufactured by deep-drawing. The outer surface of the container 10 is suitably coated. The inner shell 11 of the container 10 is preferably coated with a copper layer, so that the radiation heat emitted by the receiving chamber 14 is reflected by the copper layer, so that the hot liquid or food contained in the receiving chamber 14 remains hot for a longer period of time. The same applies to cold liquids or food.

[0041] In order to create a vacuum in the cavity 13, the container 10 is provided at the bottom 15 with a suction opening, through which the cavity 13 can be subjected to a vacuuming process, after which the suction opening is sealed in a material-locked manner, while the vacuum in the cavity 13 is maintained.

[0042] In order to connect the inner shell 11 of the container 10 with the inner shell 12, an annular fabric seam is provided along the upper outer edge. This seam is treated with care, since the annular edge in the area of the fabric seam also forms a drinking edge, in particular when drinking directly from the container 10. The fabric seam can for example comprise a welded seam or a welded joint.

[0043] As mentioned above, the magnet 2 is in the form of a flat cylinder and is arranged opposite the central region 150 of the bottom 15 of the thermally insulated container 1. The cover plate 153 comprises an outer edge 152, which surrounds an inner edge 151, which surrounds the central region 150. After assembly and welding of the cover plate 153 to the inner edge 151 of the base 15, the magnet 2 is accommodated in the central region 150 in a positive manner. At this point, the edge of the cover plate 153 is adjacent to the outer edge 152, on which the thermally insulated container 1 is standing upright. It is clear that the cover plate 153 can also be welded to the base 15.

[0044] The dimensions of the cover plate 153, the inner edge 151 and the outer edge 152 are preferably chosen such that the magnet 2, which is mounted in the central region 150 of the thermally insulated container 1, is kept at a predetermined short distance from the outer edge 152 of the base 15, with a maximum of 2 mm, preferably a maximum of 1 mm. Thus, the magnet is kept at a short distance from the metal element M on the surface, so that its attractive force can be fully exploited, so that the thermally insulated container 1 is placed in a stable upright and slip-resistant manner.

[0045] Fig. 5 The thermally insulated container 1 shown in Fig. 1 Fig. 1, and the coaster 3, which is intended for use with the thermally insulated container 1, in particular for ensuring a stable upright and slip-resistant positioning thereof.

[0046] The coaster 3 is preferably a nanogel adhesive coaster, which has a non-slip and adhesive bottom. The coaster 3 comprises a metal layer M that interacts with the magnet 2 of the thermal container 1. Thus, the bottom of the coaster 3 is designed to be non-slip and adhesive, so that it can be easily and flexibly placed in a predetermined position P, PI, P2, for example on a furniture surface, such as a table, a storage area or a shelf, and then the coaster 3 is positioned in a non-slip and adhesive manner, while being reversibly usable for cooperation with the thermal container 1. As Fig. 5 shown, the surface size of the coaster 3 for placing the thermal container 1 matches the size of the base 15, so that it is relatively large in size with respect to the base 15.

[0047] When the thermal container 1 is placed on the coaster 3, its magnet 2 interacts with the metal layer M on the coaster 3, so that the thermal container 1 is stably upright and non-slip on the coaster 3.

[0048] The coaster 3 interacts with the magnet 2 of the thermal container 1, and its bottom surface is fixed in a non-slip manner in a predetermined position P, PI or P2. As Fig. 5 shown, in addition to the coaster 3 in the position P described above, two additional example positions PI and P2 are shown schematically. As described above, the positions P, PI and P2 can each represent a predetermined position P, PI, P2 on a surface, for example a furniture surface, such as a table, a shelf or a storage area, in particular in a vehicle.

[0049] Thus, a system 1, 2, 3 for non-slip positioning of a stably upright thermal container 1 in at least one predetermined position P, PI, P2 is provided, which system comprises a stably upright thermal container 1, whose bottom 15 comprises a magnet 2, and at least one coaster 3 that interacts with the thermal container 1, wherein the coaster 3 comprises a metal layer M that interacts with the magnet 2, and the coaster 3 is designed as a nanogel adhesive coaster with a non-slip and adhesive bottom. The system 1, 2, 3 can preferably comprise a plurality of coasters 3, each of which is used to achieve stable upright and non-slip positioning of the thermal container 1 at a plurality of positions P, PI, P2.

[0050] Fig. 6 Further shown is the thermal container 1 as shown in Fig. 3 and Fig. 4 , wherein preferred dimensions and specifications of the thermal container 1 are described, in particular a preferred storage capacity of the thermal container 1 as a safe and easy-to-handle thermal cup 1 design, which will be explained below with reference to Fig. 6 . It is again pointed out that reference is made herein to Fig. 6The preferred embodiment of the thermal insulation container 1 described above only represents a preferred exemplary embodiment. As mentioned above, the thermal insulation container 1 according to the present invention is essentially unlimited in size and specifications, especially in storage capacity, and can therefore be dimensionally and structurally designed as needed.

[0051] For a better understanding, in particular with regard to the advantageous shape and arrangement of the magnet 2 in the central region 150 of the bottom 15 and the advantageous configuration of the thermal container 1 as a thermal cup 1 which is particularly suitable for the safe transport of liquid foods and for their direct consumption from the thermal cup 1, Fig. 6 Shown Fig. 3 and Fig. 4 Another schematic diagram of the heat preservation container 1 shown in FIG, also adopts a longitudinal cross-sectional view. For the sake of clarity and ease of understanding, Fig. 3 and Fig. 4 same, Fig. 6 In the figure, only the magnet 2 is indicated by a dotted line.

[0052] like Fig. 3 In the exploded view shown, as described above, the magnet 2 is located outside the central region 150 of the bottom 15 and is spaced relative thereto, while also being spaced from the cover 153. Fig. 4 In the assembled container 10, the magnet 2 is arranged in the central area 150 according to the design requirements and is covered by the cover 153. For better understanding, Fig. 6 exist Fig. 3 and Fig. 4 As shown in the combined view, the magnet 2 Fig. 3 The cover 153 is shown as being located outside and spaced relative to the central region 150 of the base 15, wherein the cover 153 is shown as being adjacent to and in predetermined contact with the magnet 2, which is consistent with the embodiment of the present invention. Fig. 4 Their relative arrangements are consistent.

[0053] Therefore, if Fig. 6 As shown, the cover plate 153 (as Fig. 1 The diagram shown in the figure contains a slightly stepped central region. Fig. 4 The assembled container 10 is shown in contact with the magnet 2. In this configuration, the cover 153 surrounds the annular peripheral region of the slightly stepped central region immediately adjacent its outer edge, which surrounds the inner edge 151 around the central region 150 and is slightly spaced from the magnet 2 in the assembled container 10.

[0054] The central area 150 of the bottom 15 is provided with a flat annular area near the inner edge 151, which surrounds the suction port bonded and sealed by the material. The suction port is located at the center of the central area 150. Therefore, the suction port forms a depression relative to the flat annular area of ​​the central area 150.Fig. 4 and 6 As shown in the figures, the magnet 2 is arranged in the central region 150 in a positive manner, near the flat annular region of the central region 150, near the inner edge 151 and near the slightly stepped central region of the cover plate 153. The magnet 2 is thus suitably arranged in the central region 150 at a distance from the bottom of the centrally sealed suction opening and, as mentioned above, also at a distance from the annular peripheral region of the cover plate 153.

[0055] In order to particularly firmly and reliably fix and cover the magnet 2 in the central region 150, the magnet 2 can be glued, in whole or in part, to the central region 150 of the base 15 and to the annular region of the cover plate 153, particularly to the flat annular region around the centrally sealed suction opening, by means of a suitable adhesive, particularly a temperature-resistant liquid adhesive, or a suitable double-sided adhesive tape / adhesive mat. A suitable liquid adhesive can be, for example, a glue based on a polymer-modified silane (MS polymer). The recessed region around the centrally sealed suction opening can be completely filled with liquid adhesive or covered in whole by a suitable adhesive tape or adhesive mat. The magnet 2 can also be clamped in the central region 150 of the base 15 by mechanical means, inserted into this region and then pressed from the side or fixed by means of screws to the base 15; the base 15 can be designed accordingly for this purpose.

[0056] The flat cylindrical magnet 2 is suitably dimensioned in relation to the central region 150, the diameter of which substantially corresponds to the diameter D2 of the magnet 2. The height H151 of the inner edge 151, which surrounds the central region 150, is smaller in relation to the height H152 of the outer edge 152, on which the upright thermal container 1 is placed. The height H2 of the flat cylindrical magnet 2 is thus selected to be smaller than the height H151 of the inner edge 151, so that the height H21 of the magnet 2, which is arranged in the central region 150 and is equipped with the cover plate 153, is slightly higher than the outer edge 152, as mentioned above. The magnet 2 accommodated in the central region 150 thus maintains a predetermined small distance, which is at most 2 mm and preferably 1 mm, from the surface on which the thermal container 1 is placed. In this way, the magnet 2 maintains a short distance from the metallic element M on the surface, so that its attractive force can be fully exploited, enabling the thermal container 1 to be positioned in a stable upright and slip-resistant manner.

[0057] The thermal container 1, which is preferably designed as a thermal cup 1 as described above and is particularly suitable for liquids, has a relatively large opening relative to the base 15 of the container 10 and a diameter D16 which is greater than the diameter D15 of the base 15 by a predetermined value, in order to enable its preferred simple and convenient handling. The thermal cup 1 thus tapers from the upper edge to the base 15, so that it is particularly easy and convenient to handle, particularly when removing or opening the lid 16 and drinking the liquid directly from the upper opening.

[0058] The thermos 1 as described above can preferably be designed as a thermos cup 1, the diameter D16 of its upper opening, the diameter D15 of its bottom 15, in particular the height H10 of its container 10, such that the filling volume capacity of its receiving chamber 14 is suitably in the range of 250 ml to 500 ml, and for ease of handling, in particular around 300 ml to 350 ml. The preferred filling volume of the thermos 1 is about 350 ml, and the thermos 1 is preferably designed as a conically tapered thermos cup 1, the diameter D16 of its upper opening is about 80 mm, the height H14 of its receiving chamber 14 is about 110 mm, the height H10 of its container 10 is about 125 mm, and the diameter D15 of its bottom 15 is about 60 mm.

[0059] The height H15 of the bottom 15 of the thermos 1 is thus suitably about 15 mm. For a thermos 1 designed as a thermos cup with a filling volume of about 350 ml, the magnet 2 needs to have a correspondingly high efficient magnetic performance in order to achieve the stable upright and slip-resistant properties as described above. The magnet 2 can advantageously be designed as a flat cylinder with a diameter D2 of about 40 mm and a height H2 of about 4 mm. In order to exactly accommodate the magnet 2 within the bottom 15, the diameter of the central region 150 and the height H151 of the inner rim 151 surrounding this region should correspond to the diameter D2 and the height H2 of the magnet 2, respectively.

[0060] The thermos 1 as described above, which is suitably adapted as a thermos cup 1, is designed with dimensions, in particular the dimensions of its magnet 2, which are aimed at achieving an ideal filling capacity in the range of 350 ml. A thermos 1 designed for a larger filling capacity, for example in the range of 500 ml to 1,200 ml, is suitably adapted in shape and dimensions. Such a correspondingly larger thermos 1, which is correspondingly heavier, in particular when filled, can comprise a magnet 2 with a correspondingly selected, moderately strong magnetic performance, wherein the magnet 2 also has a suitably dimensioned diameter D2 and height H2. Correspondingly, the bottom 15 of the container 10, in particular the central region 150 and the cover plate 153, are obviously adapted to this design in relation to the magnet 2.

As Fig. 7 The thermos container 1 shown on the left corresponds to a thermos 1 that is designed in a conical structure, whose bottom 15 narrows gradually, as Fig. 1 As shown, in particular Fig. 3 , 4 and 6, the thermos 1 is suitable for a capacity of 350 ml of liquid. The relatively large thermos container 1 placed on the circular coaster 3 is designed for a capacity of, for example, 500 ml of liquid, whose bottom 15 is also appropriately conically tapered. The larger thermos container 1 contains an upper part with a handle in order to facilitate handling of the thermos container 1. Between the upper part and the lower part of the thermos container 1, a narrow portion is formed below the handle, at which the thermos container 1 is particularly sharply tapered.

[0064] As mentioned above, in particular with reference to Fig. 6 , the larger thermos container 1 comprises an adapted magnet 2, which has an appropriately, relatively strong magnetic attraction, and in particular, its dimensions can also be correspondingly adapted. In order to enable the thermos container 1 to be stably, slip-resistant and safely upright, as Fig. 7 shown, the coaster 3 in the system 1, 2, 3 (adapted to the thermos container 1) is particularly designed with its nanogel adhesive pad, which has a slip-resistant and adhesive base, and whose dimensions match the larger thermos container 1, so that the coaster 3 is of course also suitable for the smaller thermos container 1.
