The invention relates, generally, to self-cooling containers for liquids, in particular to a self-cooling inside the container for soft drinks.

Self-cooling CCW in their design has many disadvantages. The complexity of the constructive scheme made impractical by many of the known device. In some cases, the problem was the security. The possibility of contact of the cooling agent with a refreshing drink at best creates the risk of changes in the quality of soft drink, and at worst, the risk of poisoning the consumer. There are also other devices in which there is a release of refrigerant when opening a container with a pull-tab that creates a serious security threat. When you release the evaporating refrigerant together with particles of liquid formed in its vapor is emitted upward in the face of the consumer. The solution to this problem was the subject of a U.S. patent N 3852975, author Beck (BecK), in which the proposed Bank with a protective shield designed to protect the consumer from being thrown upwards spray. Other disadvantages of the known devices are inefficient cooling and/or failure to comply with the requirements of environmental protection.

The aim of the invention is to develop an effective, simple, easy to use and economical camouflauge container for liquids, free from the disadvantages inherent in the known technical R is for soft drinks, not only convenient for the "uninitiated", and represents a cost effective alternative to additional cooling.

Another objective of the present invention is the development of "environmentally friendly" self-cooling container for soft drinks intended for use in new non-toxic osnovatelna of ftoruglevodorodnye (qualification development Department) and easily recycled after use.

These and other objectives are realized in one of the embodiments of the present invention, including the regular size container for soft drinks, meeting modern requirements in packaging, storage, transportation, loading and unloading. Along the axis of the upper chamber containing a cooled soft drink, is a chamber for the refrigerating agent attached to the base of the upper chamber and extending, at least partially, inside the upper chamber. The interior of the chamber for the refrigerating agent hydraulically isolated (fluidicly isolated from the internal region of the upper chamber.

A sealed chamber for the refrigerating agent contains a certain amount of the cooling agent in VNIIM top of the camera.

Third, the camera performs several functions. First, she plays the role of the regular emptying of the chamber for the refrigerating agent by introducing razgermetiziruetsya element in a sealed hole. Secondly, it plays the role of the chamber discharge or release node refrigerant, where the slow evaporating volatile cooling agent, which eliminates the risk of ejection of the spray liquid in the direction of the consumer. In addition, the third chamber increases cooling efficiency by maximizing the surface area of cooling, which includes not only the surface of the chamber for the refrigerating agent, but the lower part of the surface of the upper chamber for a soft drink. This third unsealed chamber can be performed in a separate, mostly cupped, cap, preferably attached to the base of the upper chamber by means of the threaded connection. The inner surface of the hood is also equipped with rethermalization elements (e.g. punching element) located coaxially sealed the hole. Rotation of the cap is attached with a threaded connection to the upper chamber, causing the displacement is constant so the release and the release of the evaporating refrigerant in the third chamber at atmospheric pressure. The resulting cooling effect of evaporation and adiabaticheskoi expansion of vapors causes cooling of the walls of the chamber for the refrigerating agent and the base of the upper chamber, causing the cooling soft drink due to the heat.

In another embodiment of the invention, the upward movement razgermetiziruetsya element can be ensured by connecting the cap and the outer wall of the top chamber with ribs and grooves.

In yet another embodiment of the invention the base of the cap may be made flexible enough to provide an upward shift razgermetiziruetsya item by pressing up, provided at the base of the cap as a means of releasing refrigerant.

In Fig. 1 shows a self-cooling container for carbonated soft drinks, beer, etc., indicated as a whole by position 10. The container is shown with the usual opening tab 15 at its upper end wall 11 and is essentially normal to the external size and shape of cans of this kind. Every part of the structure is made of a material preferably selected from aluminium, steel, aluminum, and steel, or other metal or metal alloy, plastic or other material with sufficient strength, thermal conductivity and ability to be reused after use.

The container 10 is divided into mainly three cylindrical chambers: the upper chamber representing the vessel 12 for liquid (usually for soft drink); the lower chamber, representing the vessel 21 for steams holidav along its axis and concentric with respect thereto.

Formed by the upper chamber of the vessel 12 for soft drink is limited to the surfaces of the cylindrical side wall 16, a generally disc-shaped top wall 11 and the wall of the base 13. In two preferred embodiments of the invention, shown in Fig. 2-5, the cylindrical wall 16 is in the bottom part 17 of smaller diameter. The wall of the base 13 has a hole 19, the axis of which coincides with the axis of the wall.

Formed by the lower chamber of the vessel 21 for removal is limited to individual, mainly cupped, a cap 20, having a preferably generally concave portion 27 of the base and a cylindrical side wall 22. The side wall 22 of the cap 20 fits with the shape of a circular cylinder portion 17 of reduced diameter upper chamber. The annular sealing element 22a, located along the upper open edge of the cap 20 provides a moving rotating sealing connection with having the shape of a circular cylinder part 17 of reduced diameter of the side wall 16. The side wall 22 of the cap is additionally coupled with having the shape of a circular cylinder part 17 of reduced diameter upper chamber 12 at the expense of vertical displacement, similar to the described niceboobs to the wall 13 of the base of the vessel 12 for soft drink. The capsule includes an internal cavity for the cooling agent containing a specified amount, under pressure and in liquid form, and the refrigerating agent is preferably chosen from the group of fluorocarbons, developed by DuPont and other companies. In the bottom of the capsule 30 is made a hole 19a, coinciding with the opening 19 of the base 13 of the vessel for a soft drink.

Sealing holes made through the sealing element 32, for example - pierceable seal with a piece of foil that has sufficient strength to hold under pressure refrigerant in the sealed cavity inside the capsule 30 for the cooling agent.

The cavity or region of the liquid formed by the inner walls of the vessel 12 for soft drink contains to be cooled soft drink, access to which the user can use the normal device stamped fragmentary tongue 15 (to access open hole).

The cavity or region of manufacture, formed by the inner walls of the cap 20, the outer surface of the wall of the base 13 of the vessel 12 for refreshing napii normal atmospheric pressure through the pores 29 in the base or side walls of the hood 20. The sealing element 32 thus forms a common wall (or the connecting part of the wall between the cavity in which the refrigerating agent and the scope of the issue. Within the scope of the release is attached to the inside of the part 27 of the base of the cap along its axis activator cooling, which includes razgermetiziruetsya element.

In the process of cooling soft drink contained in the Bank corresponding to the present invention, the cap 20, guided by the elements of the vertical displacement (discussed below), move up relative to the vessel 12 for a refreshing drink, while the annular sealing element 22a slides in contact with the side surface having the form of round t the slight pressure from the beginning towards the inside of matching holes 19, 19a, punching the sealing element 32, as shown in Fig.6. The refrigerant, after it has been exposed to normal atmospheric pressure, quickly evaporates and passes through the openings 19, 10a in the vessel 21 steams, where vapours slow. Capsule 30 for the cooling agent and the wall of the base 13 of the vessel 12 for soft drink are cooled by conduction to the cooling effect of evaporation and adiabatic expansion of the vapor of the cooling agent. This cooling is accordingly reported refreshing drink in a vessel 12 which is then cooled.

Expanding and evaporating the refrigerant is released from the vessel to release the vapor through the vent pores 29, as illustrated in Fig. 2 and 4 by arrows 29a. The rate of release of a pair of cooling agent regulates the efficiency of the cooling effect and is determined by the size of the holes 19, 19a, the size of the vessel 21 for steams and size of ventilation pores 29. Preferably, to further slow the rate of release of vapors to maximize the efficiency of the cooling composition includes located vertikala vapor.

The above-mentioned elements, the vertical displacement guide moving the vertical displacement of the cap 20 around having the form of a circular cylinder portion 17 of the vessel 12 for soft drink. In the preferred embodiment, on the inner side wall 22 of the threaded elements 23a, providing threaded strand connection with the respective threaded elements on the outer wall having the shape of a circular cylinder portion 17. Thus, the vertical displacement of the piercing element 26 is accomplished by rotation of the cap 20 around the vessel 12 for soft drink.

In an alternative embodiment, the invention can implement a sliding connection with the latch between the cap 20 and the vessel 12, in which on the outer side of the side wall 22 fixed many of the flange 24a, which can slide in the set of corresponding grooves 24b located on the outer wall having the shape of a circular cylinder portion 17. The device is brought into action by providing push up on the cap 20 with the shoulder 24 facing vertically in grooves 24b. Preferably, the horizontal portion of the grooves allowed to carry out the locking regards curatolo treatment).

Part of the hood 20 may be a node independent of the separately sold vessel 12 for soft drink. In this case, the cap 20 may, for example, be built into the vending machine and to ensure the availability of the seal cavity steams and punching element for multiple-use together with each sold separately vessel for soft drink exactly the same as described above.

In yet another embodiment of the invention depicted in Fig.5, the cap 20 is a single unit with the side walls 16 of the vessel 12 for soft drink. Shift up through element 26 with the purpose of punching the sealing element 32 capsules for refrigerating agent is carried out by bending up the side 27 of the base receptacle 21 for the release of vapors. Part 27 of the base depicted in Fig.5, has its Central portion 27a sufficiently deformable to achieve bias, but rather rigid in its outer part 27b to withstand the weight of the 10 banks with the minimum deformation.

Although the above description contains many details, these should not be viewed as limiting the scope of the invention, but rather as a concrete example the cooling of drinks, it is clear that it can be used for the case of banks for any liquid. There are many possible modifications. Therefore, the scope of the invention should be determined not in accordance with the illustrated variants of its implementation, and in accordance with the attached claims and their legal equivalent.
