Cooling device for liquids in holders

The invention relates to a cooling device for liquids in a container, in particular bottled beverages.

For the cooling of liquids in containers, for example drinks in Bottles, there are different possibilities. On the one hand it is possible that keep drinks bottle in the refrigerator or the cool cellar and immediately to consume. Especially with white wine, sparkling wine or other alcoholic beverages, consumed over a certain period and the like in a cooled state to be enjoyed, the cooling is only in the refrigerator insufficient or unsatisfactory. For this reason, containers are known, in the already pre-cooled beverage bottle is dropped and then on the Table or is situated at a different location. The cooling of the beverage bottle occurs, depending on the applied principle in different fashion. So cooling container are known, in which the cooling takes place by ice filled therein; as Prime example is the famous champagne bucket. Further cooling container of clay Known or other porous material, which are placed in water and the then output the information stored in them water, whereby evaporative cooling is generated, which in turn cools the set beverage bottles. Further, Known double-walled cooling container in which a certain air space exists between the container walls so that an insulation occurs. On similar principle is also, for example, by cuffs from a Insulation material achieved. Such cooling tank cause but merely states that the . Already existing temperature, eg the wine bottle is held; a Cooling down is not possible.

Furthermore, refrigerant may be filled in such a double-walled container be, as known for example from US 6,357,253. The known cooling tank exhibited numerous disadvantages. So they take the one away a lot of space, which is disadvantageous for example during storage. Especially in Catering establishments must be stored a number of these cooling containers and be kept. Furthermore, different depending on the container size Cooler required; so, for example, does not fit a bottle of champagne is usually in a wine cooler. From WO 98/30848 a device is finally known, with the fluids can be cooled. This device comprises a Adsorbent, into which pressurized gas is introduced, and whose Temperature is reduced by the gas is released. This refrigerator is in introduced a beverage can in their preparation and sealed with this. At the Opening of the can, for example by means of conventional ring closure, the gas is released and thus cooled beverage. This device brings the Disadvantage that they can be used for a once only, since they "Destroyed" by the opening of the can is. Furthermore, the adsorbent is and the cooling device is supplied with the beverage can the waste, which from is unacceptable for ecological reasons.

Object of the present invention is therefore to provide a cooling device for Liquids in containers, in particular provide bottled drinks, with which can be cooled, the liquid or at least the temperature of the holding the cooled liquid over a certain period. The cooling device is intended for be a wide range applicable to containers and it is possible be space-saving storage.

This object is achieved by a cooling device according to claim 1. Advantageous Embodiments are the subject of the dependent claims.

The inventive cooling device for liquids in containers, especially Beverages in bottles, comprises a hollow body which is filled with a coolant and is insertable into the container. In contrast to the prior Technology known refrigerated containers, in which the bottle is set, at the Cooling device of the invention this is introduced into the bottle itself. otherwise the liquid than in the known refrigerated containers thus directly in contact contacted with the cooling device and not, as in the conventional containers by the Bottle wall. The direct contact of the liquid with the Cooling apparatus is increased the efficiency of the cooling. In contrast to that of the WO 98/30848 known cooling device, the cooling device according to the invention is However, any use often and completely independent of the production process the liquid container and the filling process of the liquid. Moreover, Cooler comparatively small the invention; they pass through the Opening of the liquid container, for example, through the neck of a wine bottle. This assumes when storing a very little space.

In addition, it is provided that connected to the cooling device has a dispensing opening is, over which are guided through the liquid in the container can. Thus, the cooling device according to the invention can always in the bottle remain and must not, for example, when you pour the drink away will. Thus, the beverage is passed through the cooling device and to outside brought to be poured. For this purpose, a so-called Schenk cone provided. The latter has a conical shape with friction-increasing Means, in particular a rubber ring cone, whereby the cooling device at is different container opening sizes adaptable. It concerns with the Schenk cone around a partly perforated hollow body, that is, a hollow body, which has openings. Through these openings, the liquid is passed and at the top of the cone removed by Schenk re-opening. Of the Schenk cone is thus in the container opening can be introduced and in this the conical rubber ring securely fixed.

In the preferred embodiment takes place via the fixation of the cone Schenk the fixing of the element of the cooling device in the liquid container, in the cooling agent is contained. It is further preferred that a so-called is ventilation pipe available. It is a hollow tube having at least one lateral opening, which can be inserted into the cone and Schenk which the liquid is guided. Thus, the Schenk cone allows adaptation to the size of the container opening and the venting tube, the removal of the liquid through the Schenk cone. It should be noted, however, that there is at the vent tube is a preferred embodiment. in principle is for carrying out the invention, the cooling device described above sufficient. In order to fix this in the liquid container, the hollow body also be designed conically and holding devices in the form of rubber rings or the like have. Thereby, the cooling device in the container opening additionally fixed and protrudes with its end into the liquid. Thus, the Cooler for different container sizes applicable and space-saving to store.
