Temperature regulating mechanism 16 may include phase change material. Phase change material is a class of materials that use phase changes (e.g. melting or freezing) to absorb or release relatively large amounts of latent heat at relatively constant temperatures. Phase change material is disclosed in U.S. Pat. No. 6,574,971 to Suppes, which is hereby incorporated by reference in its entirety. Phase change materials allow for a micro encapsulation and a customized melt/freeze point. When the temperature becomes warmer than the freezing point, phase change materials liquefy and absorb and store heat. Conversely, when the temperature drops, the material will solidify and give off heat, warming the material coated or impregnated with phase change material.
Phase change materials are used for a wide range of applications in the industry, and are far superior to and comparable with ordinary ice or freeze gel for many applications. For example, the U.S. army uses a cold vest filled with a phase change material to keep soldiers cool in hot conditions; the material interacts with body heath. Phase change material may be used as an insulator for Pizza delivery packaging to keep the pizza hot during transport. It may be used in air conditioning devices to accumulate cold in order to save electricity consumption.
In embodiments, a liquid can be maintained at a prescribed temperature that is specifically tailored for the ideal temperature of the liquid. Phase change material used may be non-toxic and may be made out of food grade materials such as soy. Phase change material may be used for temperature moderation of beverages (e.g. wine), and may be formulated to interact with the aroma flavor's ideal serving temperature of a particular wine (e.g. between approximately 7° C. and approximately 19° C., depending on the wine). In embodiments, phase change material is tailored to have a melting and freezing point of approximately the ideal serving temperature of the liquid inside box 14. In other words, at approximately an ideal serving temperature of the liquid inside box 14, the phase change material (which may be tailored to the liquid) will be frozen. At temperatures above approximately an ideal serving temperature of a liquid inside box 14, phase change material in temperature regulating mechanism 16 may be liquid. When phase change material is a solid and starts to melt to become a liquid, it may absorb large amounts of heat from its surroundings and thereby keep it cooler. Conversely when phase change material starts to go from a solid state to a liquid state it will release large amounts of heat and therefore aids in alcohol from getting too cold too quickly. It is the actual process of melting and freezing of phase change material that assists in temperature moderation.
In embodiments, phase change material maintains wine in box 14 at an ideal serving temperature for the particular wine. Different kinds of wines have different ideal serving temperatures. For example, many non-vintage sparkling wines have ideal serving temperatures of approximately 7° C., while many Cognacs have ideal serving temperatures of approximately 19° C. To elaborate on this example, if box 14 contains a non-vintage sparkling wine, the phase change material in temperature regulating mechanism 16 would ideally have a critical phase change temperature of 7° C. Likewise, if box 14 contains a Cognac, the phase change material in temperature regulating mechanism 16 would ideally have a critical phase change temperature of 19° C.
In embodiments, temperature regulating mechanism 16 including phase change material is coupled to box 14. In embodiments, at least a portion of temperature regulating mechanism is visible from the outside of the box. In embodiments illustrated in
As illustrated in
In embodiments, liquid may be contained inside box 14 by being contained in a bag. The bag may contain a spigot from which the liquid is dispensed, in accordance with embodiments. As illustrated in
In embodiments, a temperature regulating mechanism may be a bag including phase change material, which also holds the liquid (e.g. wine). In embodiments, the bag may have at least two layers, with phase change material between two layers and liquid (e.g. wine) contained inside the inner layer. In embodiments, phase change material may be substantially evenly distributed between the two layers of the bag. For example, phase change material may be evenly distributed by the bag having multiple compartments isolated from each other, with each compartment containing phase change material, in accordance with embodiments. In accordance with embodiments, the multiple compartments may have a similar appear as packaging bubble wrap, with phase change material within the bubble. In accordance with embodiments, the multiple compartments may each have an elongated shape.
A two layered bag with phase change material between the layers may have the advantage of maximizing the heat transfer between the phase change material and the liquid (e.g. wine), in accordance with embodiments. As the liquid is dispensed from a box, the bag inside the box may collapse (with substantially no air entering into the bag), allowing for maximization of heat transfer between the liquid (e.g. wine) and the phase change material by maintaining the surface area contact between the phase change material in the bag and the liquid (e.g. wine), in accordance with embodiments. A temperature regulating mechanism in the form of a bag may be used by itself or in conjunction with another type of temperature regulating mechanism.
In embodiments, box 14 may contain liquid without using a bag. For example, box 14 may contain the liquid direction or box 14 may be lined with a non-permeable film. In embodiments, opening 18 may be located near the bottom of an area of box 14. As illustrated in

The foregoing embodiments (e.g. a box and a temperature regulating mechanism) and advantages are merely examples and are not to be construed as limiting the appended claims. The above teachings can be applied to other apparatuses and methods, as would be appreciated by one of ordinary skill in the art. Many alternatives, modifications, and variations will be apparent to those skilled in the art.
