Definitions

  • the present invention relates to a cooling device for a container filled with a liquid according to the preamble of patent claim 1.
  • bottles filled with liquids are stored in corresponding cooling devices during consumption.
  • these cooling devices ensure that the cooled, for example in the basement or refrigeration unit to a certain temperature liquids do not heat undesirable.
  • such cooling devices consist of a container in which a cooling liquid, such as water or a water-ice mixture, is filled. To cool the liquids, the bottles filled with the liquids are immersed in the cooling liquid.
  • a major disadvantage is that the coolant due to the atmospheric ambient temperature heats up relatively quickly and also decreases in volume and must be refilled.
  • the known cooling devices in which the bottle to be cooled is immersed directly in the cooling liquid, further have the disadvantage that when removing the bottles adheres to the outer surface of cooling liquid, which causes an undesirable dripping of the cooling liquid from the bottles and the handling of the bottles additionally aggravated, since the surface is relatively smooth by the adhering to the outer surface of cooling liquid and thus there is a risk that the smooth bottles or cans can easily slip out of the hand.
  • a cooling device has a cavity lying between two individual containers, on which a cooling liquid is partially filled, wherein the cooling device is subdivided into a lower and an upper, double-walled container, which are detachably connected to one another.
  • the cooling liquid located in the cavity can escape via the detachable connection of the lower and upper container, wherein a maximum filling of the cavity with the cooling liquid only up to the height of the lower container is possible.
  • the present invention has the object, a cooling device of the specified type so educate that the temperature of the liquid to be cooled remains almost constant over a longer period of time to ensure a particularly uniform cooling of the liquids, regardless of the liquid level in a bottle without direct Contact the bottle or can with the coolant, as well as provide a maximum amount of a coolant that can not escape.
  • a cooling device which comprises a container whose wall and / or bottom is formed with double-edged edges. As a result, a cavity is formed, which can be partially filled with a cooling liquid.
  • Such cooling devices have a plurality of advantages, which will be described in more detail below with reference to an embodiment.
  • An embodiment of a cooling device is, for example, a container in a double-walled embodiment, wherein the cooling liquid is encapsulated between the outer and inner walls of the container and thus does not come into contact with an article (bottle) to be respectively cooled or tempered.
  • the cooling liquid does not stick to the walls of an object to be cooled (bottle) in a take-out.
  • a particular advantage of the cooling device according to the invention is that a latent heat storage device is used, as z. B. consists of an aqueous Glauber's salt.
  • This cooling liquid has the particular advantage that a latent cold is stored in this liquid at temperatures below 0 ° Celsius.
  • the cooling device according to the invention must always be placed in advance, for example, in a freezer, so as to bring the coolant to the required, low temperature.
  • an aqueous salt solution is used in the space between the two container shells, but advantageous Glauber's salt, then there is the advantage that the Glauber's salt has a temperature storage point of substantially below 0 ° Celsius. This has the further advantage that when removing the cooling tank in the normal room or room atmosphere, the moisture present in the room atmosphere sublimated immediately on the outer wall of the cooling tank to an ice layer.
  • the object to be cooled (bottle) is relatively dry on the outside, when the object is not in direct contact with the cooling liquid and can therefore be taken accordingly safe.
  • a bottle immersed in the cooling device according to the invention regardless of their respective filling state relatively evenly deep into the cooling device, because due to indirect cooling of the subject (bottle) does not float in the coolant, so that ensures a particularly uniform cooling over a longer period is.
  • the cooling device according to the invention makes it possible to use a large number of different cooling liquids, so that particularly low temperatures can be achieved which are not achievable when using water or a water-ice mixture in conventional cooling devices.
  • Such cooling to relatively low temperatures is particularly desirable for those drinks that develop their full flavor only at a relatively low temperature, such as certain spirits with a high alcohol content.
  • the cooling liquid used in the cooling device according to the invention may vary depending on the application. Thus, it is possible, for example, to use water as cooling liquid, cooling temperatures of about 0 ° C. being able to be achieved with such a cooling liquid.
  • cooling liquids for example, aqueous salt solutions or glycol / water mixtures, so that temperatures of up to about -10 ° C. can be achieved by the abovementioned cooling liquids. It is also possible to use the refrigerants known from refrigeration technology, such as, for example, halogenated alkanes, as cooling liquid, these cooling temperatures permitting a range of -30 ° C. and lower.
  • Glauber's salt sodium sulfate
  • this Glauber's salt has a very low latent storage temperature of, for example, -10 ° Celsius. This causes, when the cooling container is removed from a freezer, the cooling container and the cooling sole located therein is kept cool for a very long time to -10 ° Celsius.
  • there is the aforementioned advantage that due to the extreme cold of the cooling sole form immediately on the outside of the cooling container corresponding moisture crystals, which lead to a particularly beautiful appearance of the container.
  • a cooling liquid is used according to the invention, which has very good application-specific properties.
  • the cooling liquid cools in a relatively short time to a lowest possible temperature, that the low temperature is kept as long as possible.
  • the expansion value of the coolant used should be as low as possible.
  • Such coolants are glycol-containing liquids according to the prior art.
  • a cavity extends completely over the bottom and the wall of the container.
  • the cooling device for example in the refrigerator or in the freezer to a desired temperature, then also receives appropriate cooling or temperature control of the article introduced in the cooling device (bottle).
  • the cooling effect of the cooling device according to the invention is improved.
  • a cooling device which enclose the largest possible area of an object to be cooled (bottle) and have a correspondingly large cavity with a corresponding amount of cooling liquid, in addition to keeping constant the temperature of the liquid filled in the bottle furthermore rapid cooling of the Liquid temperature, so that in such embodiments, a pre-cooling of the liquids can be at least partially dispensed with.
  • the cooling device according to the invention is preferably adapted in its shape to the shape of the object (bottle) to be cooled or tempered in each case. Since many drinkable liquids, such as sparkling wine, wine, schnapps or the like, are filled in cylindrical containers, such as glass or plastic bottles with conically constricted bottleneck, prove cylindrically shaped or cylinder-like cooling devices as widely used and thus particularly suitable.
  • the container narrows towards the bottom in the case of the cylindrically shaped cooling devices.
  • the cooling device according to the invention preferably has a container which consists of two individual containers, wherein the two containers have different dimensions in order to assemble them into one another and preferably to connect them undetachably to each other.
  • a cylindrical recess is arranged, which serves for filling the cavity of the assembled containers and is closed after introduction of the cooling liquid into the cavity.
  • the upper edge is rounded at the opening of the container, whereby the risk of injury is reduced when inserting a flat in the cooling device.
  • the inventively designed cooling device can be made of different materials.
  • it can consist of glass, metal or plastic.
  • Particularly suitable for this purpose are transparent plastics, such as, for example, polyacrylates or corresponding copolymers thereof.
  • a cooling apparatus designated overall by 1 in FIG. 1 has an outer plastic container 2 and an inner plastic container 3, which are predominantly cylindrical in shape.
  • the walls with the respectively associated bottoms 4 and 5 of the two containers 2 and 3 form a double-walled Cooling device 1, wherein the two containers 2 and 3 form a cavity 6 in the assembled state.
  • a cooling liquid 7 is arranged, which occupies a defined volume of the cavity 6.
  • the containers 2 and 3 are provided at the top with a predominantly cylindrical opening, so that in the container 3 a filled with a liquid bottle for cooling can be introduced.
  • the upper diameter d1 of the cooling device 1 is slightly larger than the lower diameter d2.
  • the inner and outer container 3 and 2 of the cooling device 1 is manufactured as a single container in a thermal injection molding process.
  • the outer container 2 has a larger diameter and a greater height than the inner container. 1
  • the inner container 3 has in the region of its opening a radially outwardly extending edge region 8, which rests upon merging of the inner and outer container 2 and 3 on the upper edge surface 11 of the opening of the outer container 2.
  • the two containers 2 and 3 made of plastic are joined together in a thermal process or by gluing in the overlying edge region of their openings.
  • the bottom portion of the outer container 4 has a relatively small, cylindrical recess 9, which serves for filling the cavity 6 of the double-walled cooling device 1 with a corresponding cooling liquid 7 and is closed after filling by means of a thermal process or by means of an adhesive bond (gluing). This ensures that an exit of the cooling liquid 7 and / or undesired evaporation of the cooling liquid 7 is avoided.
