Description

Drinking vessel, especially baby bottle or beverage keg

The invention relates to a drinking vessel, in particular a baby bottle or a beverage container such as a beverage keg.

In the following, the term "drinking vessel" is generally understood to mean a container or vessel for holding thin or viscous, for example, mushy foods, from which it is preferably possible to drink directly. thin or viscous foods, in particular beverages such as milk, water, beer or the like. The terms "cooling water" and "cooling medium" which are also used below are to be understood in a broader sense as meaning any flowable cooling medium suitable for the purposes indicated as well as any suitable medium for the transport of heat. If, in the following, the term "heat exchange" is used, it can be both a cooling and a heating, in particular of the aforementioned "content" of the "drinking vessel." A change of designation or terms for similar objects means in following no restriction.

If baby food in drinking vessels does not have the desired consumption temperature, for example, the human body temperature, which is too hot in most cases, a cooling of the contents of the drinking vessel is usually under running cold water or by waiting until the content reaches the desired temperature Has. In particular, in cases where freshly boiled, germ-free, but still hot water is used in the drinking vessel due to the temperature specifications of the manufacturers of milk and tea powder or the like for preparing baby food, in particular by mixing with milk powder or the like, the contents must be cooled to the desired drinking temperature. The time to reach the desired drinking temperature is often too long, especially because babies and toddlers become impatient and thus can cause significant problems for the caregiver. Conversely, heating a pre-prepared drink may take too long and cause similar problems. A very similar problem arises in the cooling of beverage containers and in particular of beverage kegs, such as beer kegs.

If z. B. beer in beverage containers, such as in commercial beer or so-called party kegs, does not have the desired drinking temperature, which as recommended by the manufacturer in the range between 7 and 9 degrees Celsius, which is generally chosen but sometimes even lower As a rule, a cooling of the contents of the beverage container in the refrigerator or refrigerator or in special dispensers with integrated cooling system brought about. In particular, in those cases where only immediately for the appropriate occasion for the benefit of these beverage containers are procured at short notice, this often from storage at room temperature away, the content of just this higher temperature must be cooled down to serving temperature.

All uses or vessel sizes have in common that the length of time for the cooling down of the contents to the preferred drinking temperature is very long - even with respect to the described concentrated cooling house dispensers is often given a period of up to 15 hours, but quite as a minimum duration is to be considered.

This duration is often too long or the cooling result due to insufficient cooling options unsatisfactory, not least in view of the limited cooling options that brings the size of the described beverage containers in comparison to conventional refrigerators or freezers, such as those used in private households. This just when a storage requires taking into account the number of people to be stored, the storage and cooling of several such beverage containers. Because especially with regard to the occasions that attend several people, and for which consequently several such beverage containers are kept in stock, but ideally an emptied vessel should be replaced directly by a new vessel with sufficiently cooled content, which in turn is only possible to a limited extent.

This time problem when cooling or warming of drinks or the like in the drinking vessel is found both in the home and on the road, for example. In the car. It Although there are commercially available coolers for drinking vessels. However, they usually require pre-cooled cuffs in the freezer compartment. But this solution is not suitable for traveling. Conversely, commercial warmer for heating the contents of drinking vessels in handling problematic because the content of the drinking vessel is not uniformly heated and also often associated with excessive temperatures, so that even this solution for heating and cooling is unsatisfactory.

There is therefore the task of creating a drinking vessel, especially a baby bottle or a beverage keg, which allows rapid cooling or heating and also meets the conditions for germ-free storage of the contents and for easy cleaning of the drinking vessel.

This object is achieved by a vessel with a wall having at least one element with additional surfaces, with which the heat exchange between the contents of the vessel and the cooling medium, in particular cooling water, is enhanced, the additional areas a total area of at least 50% , Preferably at least 70% of the available heat exchange surface area of the wall of the vessel (claim 1).

The invention causes an enlargement of the surface of the vessel by an element with additional surfaces available for heat exchange. With these additional auxiliary surfaces, the inner portions of the contents in the vessel are also reached by the cooling water. As has surprisingly been found, rapid cooling in an acceptable time is given when the additional areas have a total area of at least 50% of the area of the wall available for heat exchange, i. when the area available for heat exchange is increased by at least 1.5 times by introducing the additional areas. Here, among the surfaces available for the heat exchange, all surfaces suitable for this purpose are to be understood, without taking into account the filling level of the contents.

The element with additional surfaces can already during the manufacture of the vessel as well as after its production and by joining appropriately designed - A -

Individual components made. The solution according to the invention is hygienic because the contents of the vessel do not come into direct contact with the cooling water but are brought into contact only with additional surfaces which are cooled on their other side.

The invention does not lead to a limitation of the properties of commercially available vessels. In the vessel according to the invention, drinks or primarily liquid to mushy foods can still be prepared, possibly mixed, and stored and possibly eaten out of the vessel. Decisive, however, is that with the invention by additional cooling surfaces, a shortening of the cooling times for the contents of vessels is achieved, which must be brought as quickly as possible to a desired drinking or consumption temperature.

For an effective increase in the heat exchange in order to shorten the cooling of the contents of drinking vessels, it is advantageous according to a development that the wall of the element is formed and arranged on the vessel that the inner surface of the wall of the element of the contents of the vessel and the outer surface the wall of the element is touched by the cooling medium (claim 2). Thereafter, the wall of the element with which additional heat exchange surfaces are created separates the contents of the vessel to be cooled from the cooling medium and at the same time increases the size of the total area involved in the heat exchange between the contents and the cooling medium.

The material and the thickness of the wall of the element should allow a heat transfer, which reaches at least the heat transfer value of the remaining wall of the vessel (claim 3). The type of material of the element or elements will usually correspond to the material of the vessel. This may be e.g. to trade plastic or metal such as sheet metal or aluminum.

So that the volume of the vessel is not reduced too much while retaining the positive properties with respect to a rapid heat exchange, or the external dimensions of the vessel remain acceptable for everyday use with the volume remaining constant, it is preferred for the element to be at most approximately 30 % of the volume of the vessel occupies (claim 4). This is to be understood that by providing the element a maximum of about 30% of the volume of the vessel available for the contents is lost. More preferably, the element occupies at most 25% and more preferably at most 20% of the volume of the vessel.

To improve the properties in respect of heat exchange with only minimal loss of volume in the vessel by providing the element again, it is expedient that the ratio between the area occupied by the element volume and the additional surfaces of at least 1: 2 (m3 / m ²⁾ and in particular at least 1: 4.

For a further improved heat exchange, the additional surfaces are preferably arranged such that a uniform heat exchange between the contents of the vessel and the cooling medium is given (claim 5). In particular, it is expedient that the additional surfaces are arranged in the interior of the vessel and preferably along a central line of the vessel (claim 6).

An advantageous development of the vessel according to the invention is that outwardly open double-walled elements, the wall of which continues in the wall of the vessel in the vessel as cooling fins extend radially inward (claim 7). This design is particularly easy to manufacture in the manufacture of the vessel. If cooling medium is e.g. Cooling water flows from the outside over the wall of the vessel, it also penetrates into the open-ended double-walled elements and thus causes a particularly intensive cooling of the contents. Cooling media, such as cooling water flowing over the vessel, readily pass into the slot-shaped openings forming the double-walled elements, so that the internal surfaces of the elements are available as additional surfaces for the heat exchange. The slot-shaped openings optionally extend only briefly or further into the interior of the vessel, so that the inner regions of the contents of the vessel are also reached by these additional heat exchange surfaces for the heat exchange. The production of this embodiment of the elements with additional surfaces is particularly simple because they are e.g. made of plastic or metal together with the vessel itself.

According to an alternative embodiment of the invention, the element is provided with additional chen surfaces of a fixedly connected to the vessel hollow body which is arranged in such a way that between the hollow body and the wall of the vessel, an annular space for receiving, for example, liquid content is formed, wherein the cavity of the hollow body at least one input and Has outlet for the cooling medium (claim 8). In this embodiment, the entire outer surface of the hollow body is available as an additional surface for the heat exchange, so that the cooling times for the contents are significantly reduced. Nevertheless, the annular space between the wall of the vessel and the hollow body and possibly the space below and / or above the hollow body for receiving the contents of the vessel is available. In the context of the present invention, the term "annular space" encompasses not only annular configurations for receiving, for example, liquid, but also all ring-like shapes. The hollow body should preferably be arranged substantially coaxially in the vessel.

An inlet and outlet can be formed for example by a supply line and a discharge line for receiving cooling medium in or through the cavity. If an intensive cooling water flow is generated in the hollow body via the supply and discharge lines, the times for the cooling of the contents are reduced accordingly. A further improved heat exchange between the contents of the vessel and the cooling medium can preferably be achieved in that supply and discharge lines are passed through the annulus and thus directly through the contents.

According to a development of the aforementioned embodiment, the hollow body extends from an opening in the bottom or in the lid of the vessel in this and is open on at least one end face for the access of cooling medium (claim 9). This embodiment is particularly simple in the manufacture of the vessel e.g. to integrate plastic or metal. The preferably arranged in a coaxial position in the vessel hollow body takes over the cooling of the inner content areas. Particularly preferably, the hollow body is formed with the edge of an opening in the bottom or in the lid so that the hollow space can be reached through the opening.

With regard to the shape of the hollow body, all shapes come into consideration, whereby those shapes are preferred which take up as little volume in the vessel as possible, in order, as already mentioned, not to impair the handling of the vessel. Also, the hollow body may be shaped so that a plurality of cavities are formed, which are all designed to receive cooling medium. Particularly preferably, the hollow body is a hollow cylinder (claim 10). To further improve the thermal conductivity within the contents of the vessel and for a further improved drainability of the hollow cylinder may be particularly preferably formed of a plurality of sub-segments.

According to a development of the invention, the hollow cylinder is double-walled and forms an annular cavity and an interior. The annular hollow space has an inlet and outlet for cooling medium and the interior is in communication with the annular space (claim n). With this modification, compared to the aforementioned embodiments with a hollow cylinder to achieve a multiple gain, namely on the one hand a further increase in the heat exchange surface inside the hollow cylinder and on the other hand, a reduction of the space occupied by the hollow cylinder in the vessel space, which is not for the uptake of Content is available. It is therefore a particularly effective for heat exchange execution.

For the inflow of cooling water into the annular interior, at least one supply line guided through the vessel and optionally at least one discharge line for the cooling water can also be provided here. By the cooling water flow, which is generated in the annular interior of the double-walled hollow cylinder through the supply and discharge line, the heat exchange is particularly efficient.

The above development of the invention can, as far as manufacturing advantages and cleaning options of the vessel, appropriately further improve that the lower end of the outer wall of the double-walled hollow cylinder is firmly connected to the edge of the opening in the bottom of the vessel, and the annular cavity of the hollow cylinder above closed by an annular end wall and bottom open as ringför- miger inlet and outlet for the cooling water, while the interior of the hollow cylinder is open at the top and closed at the bottom. Thus, in the double-walled hollow cylinder-as well as in the annular space surrounding the hollow cylinder-contents such as, for example, drinking liquid can be taken up while the contents are in contact with each other on both sides Hollow wall flows through the cooling medium and is cooled. The proportion of additional surfaces for the heat exchange is particularly high in this embodiment.

Alternatively, it can be, in particular in training of the drinking vessel as beverage keg, the above development also further improve that the upper end of the outer wall of the double-walled hollow cylinder is firmly connected to the edge of the opening in the lid of the vessel, and the annular cavity of the hollow cylinder below closed by an annular end wall and the top is open as an annular inlet and outlet for the cooling medium, while the interior of the hollow cylinder is open at the bottom and closed at the top. Thus, in the double-walled hollow cylinder - as well as in the annular space surrounding the hollow cylinder - content such as beer can be recorded, while standing on both sides in contact with content hollow wall is detected and cooled by the cooling medium. The proportion of additional surfaces for the heat exchange is particularly high in this embodiment. The central passage opening of the hollow cylinder allows the problem-free emptying of the contents of the vessel, which usually just when using the initially described dispensers or commercially available pumping systems in the middle from above -also in this case by the inner of the two interconnected hollow cylinder outwardly closing lid piece means there (by a specially introduced or einzubringendes hole) if necessary introduced hoses or tubes upwards takes place - in this case, just through the central passage opening of the hollow cylinder therethrough. The double-walled shaft of the hollow cylinder reaches the inner portions of the contents, so that the cooling of the contents is particularly effective - in contrast to the pure cooling of the vessel on its outer wall. The closed at the lower end of the double wall shaft is achieved by top supplied cooling medium, so that the inner and outer surfaces of the double-walled shaft achieves a particularly high cooling effect.

A further preferred embodiment of the invention is that, instead of the introduced into the vessel element in the form of a double-walled hollow cylinder, which extends from the lid down as described above in the vessel to create additional surfaces for the heat exchange now exemplifies at least two of each other separate elements from the bottom, are preferably introduced parallel to each other upwardly extending into the vessel. It is preferably that is to say, a double-walled hollow cylinder divided into two halves along the longitudinal axis, ie the cross-sections of the elements running upwards in the vessel with their two outer walls and their two inner walls respectively correspond to the halved cross-section of the previously described hollow cylinder. Only a distance separates both individual elements and thus allows in preventing uneven, just z. As in beer typical deposits on the ground within the vessel, a uniform distribution of the content in the vessel (in terms of filling height and heat exchange within the content), as well as its uniform removal. Each of the two interiors of the double-walled half-hollow cylinder is closed at the top by the half rings as well as in their lateral course by the existing walls according to the present embodiment and thus separated from the content - down the cavities are through the openings in the bottom of the cooling medium accessible.

This arrangement of the elements to provide additional heat exchange surfaces is particularly suitable for use in the aforementioned tap systems, some of which already have contact with the outer wall of the respective vessels contact forming, active cooling surfaces very well, these active cooling surfaces continue such that Introducing the vessel in the dispenser this can be placed with the forming through the elements cavities on such gleichgeformte, rigid cooling elements, resulting in a very effective cooling of the contents result.

According to one embodiment of the invention, the hollow body is conical (claim 12). Here, in the case of a double-walled hollow body, one or both of the walls of the hollow body may be conical. In particular, the cleaning possibility of the vessel is improved by a conicity of the hollow body, and furthermore a good fit with the above-mentioned rigid cooling elements can be achieved. Preferably, the hollow body may be formed as a cone or truncated cone.

An alternative embodiment of the invention is that the element having the additional heat exchange surfaces consists of an adapter which is inserted between a lid and a container of the vessel or formed directly on the lid and having a cavity separate from the contents of the vessel can be flowed through by an inlet and outlet with cooling medium or otherwise coolable (claim - IO -

13).

With this embodiment, commercially available water bottles or beverage kegs can also be retrofitted with an inventive element in the form of an adapter, used between the lid and the container of the vessel, for a shortening of the cooling times. For this purpose, the lid of the vessel, for example, be designed to be removable, or have a posture or opening in the lid. There is also the possibility that the vessel, if there are no temperature problems, is used without the cooling adapter.

The cavity of the adapter may preferably be an inlet and outlet line which, when the adapter is connected to the vessel, runs through the contents of the vessel. For a particularly good heat exchange, the supply and discharge line, in particular preferably in turns, for example, run spirally.

A further development of the above embodiment of the invention is that the additional heat exchange surfaces having element consists of an adapter with a central passage opening for the liquid, which can be used between the, for example wholly or partially removed lid of the vessel and the container or directly to a instead of the actual lid to be attached lid is formed and with a hollow cylindrical, double-walled shaft whose double wall is closed at the bottom, and which can be flowed through by the cooling medium or otherwise cooled, extends into the vessel (claim 14).

The central through hole of the adapter allows to fill the container with and without inserted adapter with content or to empty or drink from the vessel. The double-walled shaft of the adapter reaches the inner portions of the contents, so that the cooling of the contents is particularly effective - in contrast to the pure cooling of the vessel on its outer wall. The shaft closed at the lower end of the double wall is flowed through by cooling water supplied from above, so that the inner and outer surfaces of the double-walled shaft achieve a particularly high cooling effect.

The central passage opening of the adapter also permits in particular in beverage bottles. the use of initially described dispensing systems or commercially available pumping systems centric from above, by means of hoses or pipes to be introduced there in this case advantageously through the central passage opening of the adapter.

According to one embodiment of the invention, the hollow cylindrical shaft of the adapter is conical. In this case, in the case of a double-walled shaft, one or both of the walls of the shaft may be conical, as already mentioned above.

Preferably, the adapter has an annular connecting part which can be screwed or clamped onto the container and onto which the lid can be screwed or clamped (claim 15), as far as it is not the embodiment in which the cover is integrated into the adapter is.

Suitably, the adapter is provided in the region of the connecting piece with flow channels for the supply and discharge of cooling water to and from the hollow cylindrical shaft.

For the cooling water flow through the hollow cylindrical shaft of the adapter is provided according to a development of the invention that the adapter has openings in the wall of the connecting part and associated with these flow channels for the cooling water, which pass into the hollow cylindrical shaft. It therefore requires only a suitable supply of cooling water into the openings of the connecting part to allow the shaft to effectively flow through cooling water in order to achieve an intensive heat exchange between the contents and cooling water.

An advantageous design of the adapter results when the adapter is designed such that arise in the connection part - in use - in addition to a central passage for the drinking liquid lateral passages between the connection part and the vessel. In this way, the contents can be freely filled into the vessel and remove again, e.g. while drinking.

Another variant of an adapter to increase the effectiveness of cooling is that the adapter can be placed on the vessel if necessary and in the adapter an open-topped double-walled hollow cylindrical shaft through a connection part of the Adapters so hineinerstreckt into the vessel, that a continuous, open at the top and bottom closed annular space for receiving hollow cylindrical cooling elements is formed, which are used in register in the annulus (claim 16). The cooling elements are in the form of cylindrical tubes, which are filled with a material of high heat capacity or made of such a material. The cooling elements can be rigid or flexible bodies. They can be cooled in the freezer compartment of a refrigerator or the like readily to very low temperatures, so that they develop a very high cooling performance after insertion into the annular space of the double-walled, hollow cylindrical shaft of the adapter. It is important here, as in all embodiments according to the invention, that the cooling elements do not come into contact with the contents of the vessel. Moreover, this adapter not only allows easy production but also easy cleaning.

A component of the invention, which acts on rapid cooling or heating of the contents of vessels, is also a container for receiving such vessels of liquids, in particular a drinking vessel such as baby bottles or beverage kegs, for cooling or heating the contents of the vessel by means of a liquid as heat exchange medium.

According to the invention, the container for cooling or heating the contents of the vessel to cooling elements, which are engageable with the additional surfaces in such a way that the contents of the vessel can be cooled or heated (claim 17). Such a container may for example be designed such that corresponding cooling elements are integrally formed with the container and come by inserting the vessel into engagement with the additional surfaces. Likewise, the container may have separate cooling elements, which must be brought manually in contact with the additional surfaces. As described above, the cooling elements can be filled with a corresponding material having a high heat capacity or, for example, can also be designed as active cooling surfaces described above.

According to an alternative embodiment, the container having a bottom and a wall into which a cooling liquid is fillable and which is open at the top for insertion of the vessel, at a preferably variable distance from its bottom one for the cooling liquid permeable intermediate bottom for placing the vessel, and its shape is adapted to receive vessels, between the wall and the wall of the container, a space for the cooling liquid is formed (claim 18). Preferably, the wall of the container is formed substantially cylindrical. In principle, a deviation from the cylindrical shape is possible, for example, a conical shape, for example, by an upwardly widening wall of the container for easier accessibility of the container is formed.

More preferably, the intermediate bottom of thin webs and / or rings, which are formed as an insert for the container or attached to the inner wall. This ensures that the space below the false floor in the container of the

Coolant can be flowed through well. The cooling effect of the container increases when in the wall of the container preferably at least one inlet and / or outlet for

Coolant is provided so that a vessel inserted into the container is flowed around by the cooling liquid, so that the efficiency of the heat exchange surfaces is increased by increasing the heat transfer.

The inlet for the Kühlfüssigkeit in the container is suitably arranged higher than the outlet, so that in a simple manner, a flow of the cooling liquid is achieved by the resulting gradient. Inlet and outlet are preferably arranged on opposite sides of the container.

Of considerable importance is a combination of the cooling effect of the aforesaid container with the cooling possibilities for the contents of the vessel in the variations given above. Thereafter, the container according to the invention is characterized in that due to its design a vessel according to one or more of claims 1-16 can be inserted into the container (claim 20). Which of the various forms of embodiment of the vessel is chosen for combination with the container according to the invention depends on the particular circumstances, for example on which cooling medium can be fed to the vessel in which form. It is important to ensure that the height between the intermediate bottom and the upper opening of the container is not too large, so that an unimpeded supply of the coolant can be made to the vessel, that is, that the upper part of the vessel projects beyond the container when - like in most cases - the coolant Feed takes place in the upper part of the vessel.

However, the coolant flow of the container and the vessel can also be connected to each other by the inlet and / or outlet in the wall of the container is preferably arranged so that liquid flowing through the inlet into the container to flow directly into the openings in the wall of the adapter and can emerge from the openings in the adapter and from the outlet in the wall of the container.

The effect of a refrigerant flowing through the container and the vessel exerts a particularly strong cooling effect on the contents of the vessel when the liquid flowing through the inlet in the wall of the container partially into the openings of the adapter and partly through the space between the container and flows through the vessel, which is particularly preferred. For this purpose, at the inlet of the wall of the container corresponding guide vanes or the like for the flow to arrange NEN to achieve at least two streams, one of which in the vessel and the cooling chambers provided there and the other in the annulus between the container and the vessel flows.

In order to be able to carry out the coolant in a targeted manner, namely without wetting the environment of the container, it is preferred that the inlet in the wall of the container be connected to a connection element, e.g. a flange or a nozzle for a hose or other conduit for supplying cooling medium is provided. As already stated, the use of a term as in the present case "cooling medium" includes not only all cooling fluids considered, but also corresponding cooling media, for example. Fluids, with which a heating is achieved.

Especially for the use of the container in motor vehicles or the like, a development of the invention is determined, according to which on the bottom of the bottom of the container a stand example by means of a thread or by means of a connector fastened bar, the base of commercial cup holders such as in motor vehicles is adapted. This training is particularly suitable for a corresponding container for cooling baby bottles. Another component of the invention is a method for cooling or heating the contents of drinking vessels by means of a cooling / heating medium, which acts on the outer surfaces of the drinking vessel. The invention is that upon cooling or heating of the contents of the vessel, additional heat exchange between the contents and the cooling / heating medium is effected on additional surfaces of elements disposed in or on the vessel, on the surfaces thereof on one side of the contents of the drinking vessel and on the other side the cooling / heating medium acts, the additional surfaces having a total area of at least 50%, preferably at least 70%, of the area of the wall of the drinking vessel available for the heat exchange (claim 21). Which means can be used to carry out the new cooling / heating process is apparent from the foregoing description.

A illustrated in Fig. 1 drinking vessel 1, a baby bottle made of plastic has at its upper open end a screw-on lid 2, in which a suction device 3 is used in the usual way. To create additional surfaces for the heat exchange between the contents of the drinking vessel 1 and existing cooling surfaces, hereinafter referred to as outer surface 4, an element 5 is arranged in the drinking vessel 1, which consists of a hollow body, namely a double-walled hollow cylinder 6 made of plastic.

An outer wall 7 of the hollow cylinder 6 is fixedly connected to the edge 8 of an opening 9 in the bottom 10 of the drinking vessel 1. Suitably, the drinking vessel 1 and the hollow cylinder 6 are formed together from plastic. At the upper end, the outer wall 7 merges into a ring 11 which forms the end face of the hollow cylinder 6 and which carries at the inner edge a cylindrical inner wall 13, which at the lower end in the amount of Bodens 10 with a disc 14 is completed.

Between the wall 15 of the drinking vessel 1 and the outer surface 16 of the hollow cylinder 6 there is an annular space 17, in which as well as in the interior 18 of the hollow cylinder 6 and in the remaining areas of the drinking vessel 1 content, e.g. Drinking fluid such as milk, is taken when filling the drinking vessel 1. For the interior 18 of the hollow cylinder 6 is open at the top, so that drinking liquid or the like easily enter the hollow cylinder 6 and can be removed from this again.

As illustrated by arrows Pi, cooling medium such as cooling water can enter the cylindrical cavity 19 of the hollow cylinder 6, there, as indicated by arrows P2, flow through the cavity 19 and exit after the heat exchange from the cavity 19 again, as indicated by arrows P3 and P4 is indicated in the drawing.

The area for the heat exchange gained by the element 5 in the form of the hollow cylinder 6 in this embodiment for the heat exchange between the contents of the drinking vessel 1 and the cooling water consists in this embodiment mainly of the outer surface 16 and the inner wall 13 of the hollow cylinder 6. It lies on the hand that the cooling effect of the cooling water by this increase in the available heat exchange surface area is much more intense than without the hollow cylinder 6, with the result that the contents of the drinking vessel 1 can cool much faster than without this Element 5.

With this embodiment, it is possible to provide additional surfaces with a total area in the range of about 90% of the available for the heat exchange outer surface 4 of the vessel 1.

In the further exemplary embodiment illustrated in FIG. 1A, the embodiment of FIG. 1 is developed further. The drinking vessel 1 of Fig. 1 is in this case in a cooler K used, which consists of a large hollow cylinder generally with a wall ib and a small hollow cylinder ic with a wall id, which are connected to each other via a common ground in a coaxial position. Hollow cylinder ia, hollow cylinder ic and the ground ie consist of a material with high heat capacity. For cooling the above shown in Fig. IA placed drinking vessel 1, this is used in such a way in the large hollow cylinder generally that the wall ld of the small hollow cylinder ic enters the cylindrical cavity 19 of the drinking vessel 1 and this fills as completely as possible. The wall 15 of the drinking vessel 1 comes to rest on the inner wall of the large hollow cylinder generally. It goes without saying that the cooler K has previously been cooled down to a correspondingly low temperature. In this way, the inner and outer surfaces of the hollow cylinder 6 are effectively cooled by the wall ld of the hollow cylinder ic, and accordingly, the inner surface of the wall ib of the large hollow cylinder generally exerts a correspondingly intensive cooling effect on the wall 15 of the drinking vessel 1. Also, the bottom of the hollow cylinder 6 and the bottom 10 undergo a corresponding cooling by the common floor ie. For a better understanding of the drawings, the closed surfaces of the bottom 10 of the drinking vessel 1 are hatched. The same applies to the common ground.

Instead of the above-described double-walled hollow cylinder, which thus consists of two mutually parallel and coaxial walls 7, 13, at least one of these two walls may deviate from a non-uniform cylindrical, but rather have a variable, such as conical course, as in Fig. IB shown, wherein the achievable total area of the additional areas compared to the previous embodiment does not change significantly.

FIG. 1B shows a second exemplary embodiment of a drinking vessel 1 in a perspective view. FIG. As shown, the walls are 7.1 and 13.1 of the element 5 relative to the wall 15 of the drinking vessel arranged at an angle.

Thus, the embodiment shown in Fig. 1B in the drinking vessel 1 to provide additional surfaces for heat exchange, an element 5, which is formed of two interconnected, while oppositely arranged hollow truncated cone surfaces, which form a double-walled hollow body 6.1, the walls 7.1 and 13.1 thus run in opposite directions.

The outer wall 7.1, which is formed by an outer, in the drinking vessel 1 in the upward direction, based on the radius tapered hollow truncated cone, is with the edge 8 of an opening 9 in the bottom 10 of the drinking vessel 1 firmly connected. At the upper end, the outer wall 7.1 merges into the ring 11, which forms the end face of the resulting element 5 and which carries at its inner edge 12 the opposite, thus downwardly tapered hollow truncated cone as inner wall 13.1 of the double-walled hollow body 6.1 , wherein the inner wall 13.1 is closed at the lower end at the level of the bottom 10 with a disc 14.

Between the wall 15 of the drinking vessel 1 and the outer surface 16.1 of the hollow body 6.1 is also in this embodiment, an annular space 17.1 for receiving content such. As drinking liquid available, in addition to the upwardly open interior 18 of the hollow body 6.1 and the other areas of the drinking vessel. 1

In the present case, cooling can already be described as described at the beginning of FIG. The essential advantage of this exemplary embodiment lies in further improved cleaning properties of the interior of the vessel 1.

As an alternative to the embodiment shown, only one wall 7.1, 13.1 can likewise be made conical, while the other wall 13.1, 7.1 runs parallel to the wall 15 of the vessel 1.

In the further exemplary embodiment illustrated in FIG. 1C, the exemplary embodiment of FIG. 1B is developed further. FIG. 1C provides a cooler K into which the vessel 1 according to the embodiment shown in FIG. 1B can be inserted. Structure and function of the radiator K essentially correspond to the radiator K shown in FIG. 1A, the shape of the hollow body ic.i being adapted accordingly, so that the wall ld.i of the hollow body lc.i comes into engagement with the hollow body 6.1 ,

Due to the shown conical shape of the hollow body 6.1 and lc.i in the present case easier insertion of the drinking vessel 1 in the cooler K is possible, which is explained that between the walls of the described hollow body 6.1 and lc.i as contact surfaces not immediately upon insertion contact exists, but only after complete seat, which makes the introduction significantly easier. In addition, the contact of the wall 7.1 is improved with the wall ld.i of the hollow body lc.i. The embodiment shown in Fig. ID also shows a drinking vessel 1, here a baby bottle made of plastic or glass with a substantially cylindrical container profile, as described above.

In the present embodiment, to create additional surfaces for the heat exchange between the contents of the drinking vessel l and existing cooling surfaces of the drinking vessel i, an element 5 is arranged in the drinking vessel 1, consisting of a one-sided open hollow body 6.2 in the form of a hollow truncated cone of glass or Plastic exists.

The outer wall 7.2 of the hollow body 6.2, which is formed by the up into the drinking vessel 1 inwardly, based on the radius tapered hollow truncated cone jacket is firmly connected to the edge 8 of an opening 9 in the bottom 10 of the drinking vessel 1.

At the upper end, the outer wall is 7.2 in a disc 11, which forms the end face of the resulting element 5 and the hollow body to the content, namely the drinking liquid, towards closes.

Between the wall 15 of the drinking vessel 1 and the outer wall 7.2 of the hollow body 6.2 there is an annular space 17.2, as well as the other areas (ie also above the hollow body) of the drinking vessel 1 for holding content such. B. Drinking liquid is available.

Coolant -starr or fluid- can penetrate or be introduced through the opening 9 in the cavity 19.2 of the hollow body 6.2 created as described above, flow through this in the case of fluid media and reach before the re-emergence as the additional heat exchange surfaces, which by the disc 11 and the outer wall 7.2 are formed, or in the case of rigid media touch these aforementioned contact surfaces, whereby the heat exchange is brought about at these additional surfaces.

The present embodiment has the advantage that it is particularly easy already in the Production of the actual vessel can be introduced, not least because due to the conical shape of the element 5, a slight separation of the finished vessel 1 from a mold, such as an injection mold, is possible. Furthermore, the drinking vessel 1 is easy to clean in this design despite the introduced element 5 from the inside.

The embodiment shown in Figs. IE and iF shows a drinking vessel 1, which has an element 5 in the drinking vessel 1 to provide additional surfaces for the heat exchange, which represents a further development of the one-sided open hollow truncated cone shown in FIG.

In the present embodiment, a hollow body 6.3 is provided which has concavely curved outer walls 7.3. As a result, the hollow body 6.3 has additional surfaces with a total area that essentially corresponds to the total area of the hollow body 6.2 from FIG. However, the hollow body 6.3 of the present embodiment takes up much less volume of the vessel 1, so that the vessel 1 can absorb significantly more liquid.

The outer wall 7.3 of the hollow body 6.3 described here is also firmly connected to the edge 8 of an opening 9 in the bottom 10 of the drinking vessel 1, as can be seen in particular from the bottom-side plan view in Fig. IF. At the upper end, the outer wall 7.3 merges into a correspondingly shaped disk 11, which forms the end face of the resulting element 5.

In the further exemplary embodiment illustrated in FIGS. 2-4, the drinking vessel 1 at the upper open end is in turn provided with a cover 2 into which a suction device 3 is inserted. The elements 5 for creating additional heat exchange surfaces here consist of cooling fins 21, which extend radially inwardly into the interior 18 of the drinking vessel 1, as shown in the drawing. The wall 20 of the cooling fins 21 continues in the wall 15 of the drinking vessel 1, as can be seen in particular from FIG. 3. This illustrates how easy this embodiment is to manufacture. Both walls 20 of the double-walled elements 5 in the form of cooling fins 21 form additional surfaces for the heat exchange between the contents of the drinking vessel 1 and a guided outside of the wall 15 of the drinking vessel 1 cooling medium, the without can further enter the open cooling fins 21 and get out again.

With the present embodiment, it is possible to provide additional surfaces with a total area in the range of about 90% of the available for the heat exchange outer surface 4 of the vessel 1. Advantageously, in the present embodiment, only 15% loss of volume of the vessel 1 through the cooling fins 21 with respect to a corresponding vessel without cooling fins 21.

In the embodiment illustrated in FIGS. 5A-5C, an adapter 22 is inserted between the cover 2 and the base container of the drinking vessel, as illustrated by the arrows P5 and P6. The adapter 22 has an annular connecting part 23 for receiving the lid 2 at the upper end and the base container of the drinking vessel 1 at the lower end. In the connecting part 23 coaxially extends a hollow cylindrical double-walled shaft 25 which is closed at the lower end and merges at the upper end in flow channels 28 in the connection part 23, to which a coolant via an inlet 26 has access, the flow channels 28 on the Inlet 26 opposite side leaves again through an outlet 27, as indicated in Fig. 5B and 5C by arrows P7, P8. After entering the flow channels 28, however, the coolant first flows through the shaft 25 connected to the flow channels 28, whose outer wall 29 forms an annular cavity 30a with the inner wall 30. From the cavity 30a, the cooling medium passes through the flow channels 28 to the outlet 27 forming the outlet.

When the drinking vessel 1 is finished assembled from the components shown in FIG. 5A, ie when the adapter 22 is located between the lid 2 and the basic container of the drinking vessel 1, the drinking vessel 1 is ready for use. Before in the basic container of the drinking vessel 1, the contents such as milk has been filled or prepared, so that the adapter 22 dips into the milk during assembly with its shaft 25 and 25 are started by supplying cooling medium into the hollow cylindrical double-walled shaft 25 immediately with the cooling so that the milk can reach the desired consumption temperature as quickly as possible. Via lateral passages 31 (see Fig. 5B) and the central passage 32 in the connection part 23 of the adapter 22, the milk can be removed unhindered via the suction device 3 from the drinking vessel 1. Through the ways the flow medium through the connecting part 23 and at the bottom by a ring 33 around closed shaft 25 a complete separation between the cooling medium and the contents of the drinking vessel 1 is ensured. The surfaces of the outer wall 29 and the inner wall 30 of the shaft 25 form additional heat exchange surfaces, so that a rapid cooling of the contents of the drinking vessel 1 can be achieved.

An alternative embodiment of an adapter 22.1 is shown in FIGS. 6 and 7. In the present embodiment, an adapter 22.1 is used with an element 5 arranged therebetween between the cover 2 and the basic container of the drinking vessel 1 as illustrated by the arrows P5 and P6.

The adapter 22.1 has an annular connecting part 23.1 for receiving the lid 2 at the upper end and the base container of the drinking vessel 1 at the lower end. At the connection part 23.1, an element 5 with additional surfaces for the heat exchange in the form of a coaxially arranged, spiral tube 25.1 with a wall 29.1 and a cavity 30b, which has the openings 26 and 27 for carrying or for receiving coolant in the connection part 23.1 ,

The center line, about which the described spiral-shaped tube 25.1 runs, is substantially coaxial with the connection part and in the drinking vessel 1, which is completed by joining the individual components, as shown in FIG. 7, also essentially coaxially with the outer wall 15 of the vessel 1.

The drinking vessel is assembled as shown in Fig. 7 directly ready for use. Previously, in the vessel 1, the content has been filled or prepared in the form of drinking liquid, so that the adapter 22.1 immersed with the spiral tube 25.1 in the drinking liquid and can be started by supplying cooling medium into the cavity 30b immediately with the heat exchange , As shown in this embodiment by the arrow P7, the coolant flows through the opening 26 in the spiral system, continues to follow as shown by the arrows P9 to exit through the opening 27, as shown by the arrow P8, and thus provides in the flowed through cavity 30b over the

Wall 29.1 for additional heat exchange. The advantage of this embodiment lies in the proportion of the large length of the spirally rotated tube 25.1 with its in consequence large, relevant for the additional heat exchange surface to the occupied volume, since the volume of the thus formed element 5 is comparatively low. It is thus possible to provide additional surfaces for heat exchange with a total area in the range of at least 90% of the area available for heat exchange surface of the outer surface 4 of the vessel 1, wherein the element 5 occupies advantageously only 10% of the volume of the vessel 1 ,

Furthermore, advantageously, the drinking liquid, so the content can be removed unhindered, since the passages are not blocked by the adapter to the lid 2 with the suction device 3.

In the embodiment illustrated in FIGS. 8 and 9, another embodiment of an adapter 34 will be described. The adapter 34 has a connection part 38 with an annular opening 41, at the edge 40 of which the outer wall 36 of a hollow-cylindrical double-walled shaft 35 adjoins, which protrudes below the connection part 38 downwards, as the drawing shows. Between the outer wall 36 and the inner wall 37 of the shaft 35 a closed bottom and open at the top annular space 39 is formed. This serves to accommodate a hollow cylindrical cooling element 42 made of a material with high heat capacity, which can be accurately inserted into the annular space 39, as the arrow P10 illustrates. After filling the contents e.g. Milk in the basic container of the drinking vessel 1, shown in the lower part of Fig. 8, if there is a need for cooling the milk as soon as possible, the adapter 34 can be placed on the base container, wherein the connecting part 38, the upper edge of the base container über-. engages and the shaft 35 extends with the cooling element 42 therein into the drinking vessel 1 and thus into the milk filled there, as shown in the lower part of Fig. 9. The surfaces of both the outer wall 36 and the inner wall 37 of the hollow cylindrical double-walled shank 35, which here forms the element 5, provide additional surfaces for the heat exchange, i. for cooling the contents of the drinking bottle 1, in which case the cooling effect by using the cooling elements 42 is particularly high.

After the cooling process, the adapter 34 is removed from the drinking vessel 1, as indicated by arrows P 12 is illustrated - the placement of the adapter 34 on the drinking vessel 1 illustrates arrow P n - removed and replaced by the cover 2 with the suction device 3, as shown in FIG. 9.

10 and 11 show a cylindrical container 43 consisting of a wall 46 and a bottom 47 made of plastic or metal, for receiving a drinking vessel 1 (see Fig. 5-7), as is illustrated by the arrow P13 in Fig. 10 , The container 43 has in the upper region in the wall 46 an inlet 44 for a cooling medium, which can leave the container 43 through an outlet 45 again, which is the inlet 44 opposite, but is arranged lower than this. In the lower part of the container 43 is a preferably adjustable in height at a distance above the bottom 47 of the container 43 arranged intermediate bottom 48 of thin webs 49 and a ring 50, as the drawing shows. The intermediate bottom 48 receives the drinking vessel 1 when it is inserted into the container 43, as shown in Fig. 11. When the drinking vessel 1 is in the container 43, the wall 15 of the drinking vessel is also cooled by the cooling medium, which flows through the container 43 via the inlet 44 and the outlet 45.

As illustrated in FIG. 11, the cooling medium flowing into the container 43 through the inlet 44 may flow partly into the annular space 51 between the drinking vessel 1 and the wall 46, as illustrated by the line P14 in FIG. 11, while the cooling medium is for other part in the connecting part 23 and from there into the hollow cylindrical double-walled shaft 25 can enter, as indicated by the arrows 15. These coolant flows leave the shaft 25 and the connecting part 23 of the adapter 22 again via the opening 27 (see arrow P16), in order then to leave the container 43 via the outlet 45 together with the coolant flow from the annular space 51. In this way, the container 43 causes a lasting increase in the cooling effect, which already takes place by using the adapter 22.

In Fig. 12 and 13, a development of the container 43 of Fig. 10 and 11 is shown. In this embodiment, the inlet 44 in the upper region of the container 43 with a flange 52 for locking a funnel element or for connecting a hose to which a cooling or heating medium is supplied for example via the air conditioner, provided in the use of the container 43 in motor vehicles , Below the bottom 47 of the container 43, a base 53 can be attached by means of a thread or by means of a plug-in connection, which serves to insert the container 43 into conventional cup holders.

In the embodiment shown in Figs. 14A-14C, the embodiment of Fig. 8.9 is developed further. An adapter 34.1 here also has a connection part 38.1 and an annular opening 41. At the edge 40 of the opening 41, the outer wall 36 connects to a double-walled shaft 35.1, which projects below the connection part 38.1 downwards. The double-walled shaft 35.1 is in this case formed by an outer wall 36 and inner wall 37, which, in contrast to the previously described embodiment of Fig. 8.9 are not parallel to each other, but are arranged angularly relative to each other, whereby the annular space 39.1 tapers towards the bottom.

The outer wall 36 and the inner wall 37 are in turn connected to each other at the lower end by the ring R, whereby at the same time the cavity formed within the shaft 35.1 to the contents of the vessel 1 is completed. The disc S closes inside wall 37.1 upwards.

As shown by the arrow Pn in Fig. 14A, the thus formed element 5 is immersed with the additional heat exchange surfaces with its shaft 35.1 in the content, namely, when the adapter 34.1 is placed on the base container of the drinking vessel 1. The function will be further described in Fig. 14B, when, for example, the usual trivial water bath is used to cool drinking liquid in baby bottles. In this case, cooling water W2 pours from the water crane Wi not only around the outer wall 15 of the drinking vessel 1 and causes a heat exchange between the content and cooling water W2 at this point, but rather also simultaneously - as illustrated by the arrows PW - after entering through the opening 41 of the adapter 34.1 through the annular space 39.1 and causes there at the walls additionally provided with the walls 36 and 37 and the ring R also heat exchange between the contents and the cooling medium, before it can also escape through the opening 41 again.

After the cooling process, as shown in FIG. 14C and illustrated there by arrows P12. light, the adapter 34.1 removed from the drinking vessel 1 and replaced by the lid 2 with the suction device 3, whereby in a row the so completed drinking vessel is ready for use.

Of course, in the embodiment shown above, a correspondingly adapted Kühlelelemt 42, as shown in Fig. 8, also be used. Likewise, alternatively, only one of the walls 36, 27 may be conical, depending on the application.

In the embodiment shown in Fig. 15 of a vessel 1, a beer keg made of sheet metal, to create additional surfaces for heat exchange between the contents of the vessel 1 and existing cooling surfaces, hereinafter referred to as outer surface 4 of the vessel 1, an element 5 is arranged consists of a double-walled hollow cylinder 6 made of sheet metal.

An outer wall 7 of the hollow cylinder 6 is fixedly connected to the edge 8 of an opening 9 in the fixed cover 2.2 of the vessel 1. Suitably, the lid 2.2 of the vessel 1 and the hollow cylinder 6 are formed together from sheet metal. At the lower end of the outer wall 7 of the hollow cylinder 6 passes into a ring 11 which forms the end face of the hollow cylinder 6 and the inner edge 12 carries a cylindrical inner wall 13 which is closed at the top in the amount of the lid 2 with a disc 14 ,

Between the wall 15 of the vessel 1 and the outer surface 16 of the hollow cylinder 6 there is an annular space 17, as well as the Innnenraum 18 of the hollow cylinder 6 and the remaining areas of the vessel 1 content, ie z. B. drinks such as beer, absorbs. Because the interior 18 of the hollow cylinder 6 is open at the bottom, so that the relevant content (sufficient ventilation provided) easily enter the hollow cylinder 6 and can be removed from this again.

The distance between the lower end -the ring 11- of the hollow cylinder 6 to the bottom 10 of the vessel is chosen here so that the contents of the annular space 17 and the interior 18 are not completely separated from each other or in the hollow cylinder 6, so that a uniform removal the content is possible and at the same time uneven possibly possible Deposits of the content at the bottom 10 can be avoided, which is why in this embodiment, the hollow cylinder 6 is inserted from the fixed cover 2 downwardly extending into the vessel 1 and not from the bottom 10 extending upward.

For a better understanding of the drawing, the closed surfaces of the fixed lid 2.2 are shown hatched in addition to ring 11 and disc 14 of the hollow cylinder 6 and the bottom 10 of the beverage container 1.

As illustrated by the arrows Pi, a flowable cooling medium can enter the hollow cylindrical annulus 19 of the double-walled hollow cylinder 6 through the opening 9, there, as indicated by the arrows P2, the cavity 19 and flow after the heat exchange therefrom also through the opening 9 again emerge, as indicated by the arrows P3 and P4 in the drawing.

The area gained by the element 5 in the form of the hollow cylinder 6 in this embodiment for the heat exchange between the contents of the beverage container 1 and the cooling medium consists here mainly of the outer surface 16 and the inner wall 13 of the hollow cylinder 6 together with its annular surface 11. It lies on the hand, that the cooling effect of the cooling medium by this increase in the available heat exchange surface area is much more intense than without the hollow cylinder 6, with the result that the contents of the beverage container can cool much faster so without this element. 5 ,

With this embodiment, it is possible to provide additional areas with a total area in the range of about 90% of the area of the outer surface 4 of the vessel 1.

In the further embodiment illustrated in FIG. 16, analogous to the embodiment with respect to FIG. 15, the heat exchange relates to the additionally obtained heat exchange surfaces with the aid of the element 5, which, however, does not flow through a fluid cooling medium in this example. Alternatively, in this case, as indicated by the arrow P17, here a cylindrical cooling element 42.2 introduced in its function as a cooling medium through the opening 9 into the cylindrical cavity 19 of the hollow cylinder 6 in register so that this as completely as possible is filled. The outer wall Ki of the cylindrical cooling element 42.2 abuts in succession on the outer surface 16 of the hollow cylinder 6, the inner wall K2 of the cooling element 42.2 corresponding to the inner wall 13 of the hollow cylinder 6 and the annular lower end K3 of the cylindrical cooling element 42.2 on the ring 11 of the hollow cylinder. 6 It goes without saying that the cooling element 42.2 has previously been cooled down to a correspondingly low temperature. Alternatively, the cooling element 42.2 may be formed as a component of a corresponding cooling container or a cooling system.

In the further exemplary embodiment illustrated in FIGS. 17, 18, instead of the individual element 5 introduced into the vessel 1 in FIG. 15 and FIG. 16, which extends from the cover 2.2 down into the vessel 1, additional surfaces are created for the heat exchange now exemplified two elements, this time from the bottom 10, parallel to each other upwardly introduced into the vessel 1. These elements 5 are connected to the bottom 10 of the vessel 1 via their walls W and their outer edges 8a and their inner edges 12a.

Incidentally, the function of these two elements 5 is analogous to the function of FIGS. 15 and 16 with regard to the admission of cooling media, the individual double-walled hollow cylinders being to a certain extent divided, i. H. the cross sections of the upwardly extending in the vessel 1 elements 5 with its two semi-cylindrical outer walls 7a and its two semi-cylindrical inner walls 13a respectively correspond approximately to the half-section of a previously used double-walled hollow cylinder.

Only one passage with a distance A between the walls W separates both individual elements 5 and thus enables prevention of uneven deposits

(as they are just observed with beer) at the bottom 10 within the vessel 1, a uniform distribution of the content in the vessel 1 as well as its uniform removal.

Each of the two inner spaces 18a of the double-walled "half hollow cylinder" 6a is closed at the top by the half rings 11a as well as in the lateral course through the now required walls W and down through the openings 9a for

Cooling media accessible, as shown by the arrows Pi.

This arrangement of the elements 5 to provide additional heat exchange surfaces particularly suitable for use in the aforementioned tap systems, some of which already have contact with the outer wall 15 of the respective vessels 1, active cooling surfaces - very well, these active cooling surfaces continue such that when introducing the vessel 1 in the dispensing system this can be placed with the forming through the elements 5 cavities on such gleichgeformte, rigid cooling elements, which has a very effective cooling of the contents result. The total area of the additional areas substantially corresponds to the total area of the exemplary embodiment according to FIG. 15.

Fig. 19 shows a development of the embodiment of FIGS. 17 and Fig. 18 in that u. a. with the aim of better circulation of flowable coolants within the cavity of these elements 5, the previously described double-walled "half hollow cylinder" 6a are not closed within the vessel 1 by half rings to the content, but extend into the lid 2.2 of the vessel 1 and there as well as in the bottom 10, analogous thereto through the openings 9a the cooling medium (as explained by the arrows Pi or P4) inlet in or outlet from the elements 5, allow. With the present embodiment, a total area of the additional surfaces in the range of approximately 100% of the surfaces of the outer surface 4 of the vessel 1 available for the heat exchange is advantageously made possible.

The embodiments shown by way of example in FIGS. 20 and 21 show further possibilities of shapes or cross sections of individual or a plurality of elements 5 which, arranged in vessel 1, according to the invention, introduce additional surfaces for heat exchange.

The elements with the walls 8.14 and 8.15 are connected to the bottom 10 of the vessel 1, from where they extend into the interior of the vessel 1. Alternatively, the elements may of course also extend from the lid 2 into the vessel or be formed continuously, as shown in the embodiment of FIG. 19. Here, as in the previous examples, a uniform but also a deviating, preferably tapering or conical cross section over the entire length of the respective element 5 can be selected. The elements 5 are open in each case via their openings 9.14 or 9.15 for coolant, which thus flows into the created cavities of the elements. enter and exit.

Specifically, the cross-section shown in FIG. 21 offers itself in the case of larger vessels 1 (beer kegs) for the use of commercial, rectangular cooling elements, which - pre-cooled in Eisfach- can be introduced into the here exemplarily selected rectangular opening of the element 5 and the so Senses of the invention can come into contact with the additional cooling surfaces in the interior of the vessel and thus significantly enhance the heat exchange, which (possibly in conjunction with a pushed around the wall 15 of the vessel 1 also commercially available cooling sleeve) for a very rapid heat exchange and due to a much faster cooling to serving temperature leads, as with the outer cooling sleeve alone.

These embodiments shown here are in their form regardless of their use, which allows a contribution or Anformung both in small drinking vessels in particular baby bottles and in larger beverage containers in particular beer kegs, but also the use of the aforementioned adapter solutions. Specifically, the use in larger containers with a fixed lid (2.2) but also allows as shown in Fig. 19 an arrangement from the bottom of the vessel into the lid inside, the openings 9.14 and 9.15 then both in the bottom 10 and in the lid ( 2.2) are open for cooling media, which in turn provides for the cooling of beer kegs in the refrigerator in particular for a good circulation of the cooling air within the hollow elements 5.

In the further exemplary embodiment illustrated in FIGS. 22 and 23, the elements 5 provide additional heat exchange surfaces within the beverage container 1 consisting of four cooling fins 20 which extend radially inwards into the interior 18 of the beverage container 1, as shown in FIG the figure 32 is shown. The wall 19 of the cooling fins 20 is in each case in the wall 15 of the beverage container 1, as can be seen in particular from Fig. 23, away. This illustrates how easy this embodiment is to manufacture. Both walls 19 of the double-walled elements 5 in the form of the cooling fins 20 form additional surfaces for the heat exchange between the contents of the beverage container 1 and a guided outside of the wall 12 of the beverage container 1 cooling medium, which readily enter the open cooling fins 20 and again emerge or can be introduced. The present embodiments are solely illustrative of the invention and the preferred embodiment and are not meant to be limiting. In particular, details of the exemplary embodiments explained for a baby bottle can, if appropriate, of course also be used on other vessels, such as beverage barrels, and vice versa.
