Description

The self-cooled pop can

The utility model relates to a kind of beverage cans that can cool voluntarily.

In the existing technology, " self-chilling beverage jar " as " world inventions " o. 11th inside front cover publication in 1987, it installs a chiller additional in typical beverage can, a plenum chamber that produces carbon dioxide is arranged in the chiller, when the compressing tablet of beverage can is pulled up, be positioned at the capillary break-up that the chiller in-to-in has indentation, carbon dioxide is just gently overflowed from the spiral tubule, absorb heat and carry out interchange of heat, reach the purpose of cooled beverage by air chamber wall and beverage.Its complex structure produces carbon-dioxide plenum chamber processing difficulties.November 3 nineteen ninety, the application number of application was 90219259.0, name is called the patent application of " self-chilling beverage jar ", it is to fix a fridge equipment below the beverage can loam cake, fridge equipment comprises housing, is fixed on the barrier film in the housing, be placed on the cooling system conditioner 1 of barrier film top, be placed on the cooling system conditioner 2 of barrier film below, traction piece is captiveed joint with draw ring with barrier film, the pulling draw ring draws back barrier film through traction piece, chemical reaction takes place in two kinds of refrigerant contacts, produces negative heat of solution, carry out interchange of heat through fridge equipment outer wall and beverage, beverage is turned cold.Above-mentioned two kinds of fridge equipments all are to carry out interchange of heat by the outer wall of fridge equipment and beverage to freeze, and refrigerating speed is slow, and it is inhomogeneous to freeze, and the refrigerant consumption is big.

It is fast that the purpose of this utility model provides a kind of refrigeration, and refrigeration is even and directly carbon dioxide is dissolved in the self-chilling beverage pop can that beverage becomes soda in process of refrigerastion.

The utility model comprises: original pop-top can tank, the pop can capping of closed tank, the pop can that is positioned in the capping draws lid and jar beverage, one end be fixed under the pop can capping or be fixed on the pop can jar at the bottom of on the container of storage refrigerant, container contain liquid carbon dioxide refrigerant, the other end of the container of storage refrigerant is provided with the container aie escape valve.It is characterized in that the container aie escape valve is to be arranged in a jar beverage liquid, one backguy of container aie escape valve captive joint, the backguy other end draws lid to captive joint with pop can.

During use, open pop can and draw lid, drive backguy and open the cryogen vessel aie escape valve, the liquid carbon dioxide refrigerant is sprayed by aie escape valve under container internal pressure, distillation becomes outside the bubble emersion jar after passing jar interior beverage layer absorption heat, thereby a jar interior beverage is lowered the temperature rapidly.Principle of design of the present utility model is: have the heat absorption back according to the liquid carbon dioxide refrigerant and gasify without liquid state, promptly Sheng Hua characteristics principle is a foundation.Liquid CO 2 is the mineral compound refrigerant, and the refrigerant code name is R744, chemical molecular formula: CO2.Standard atmosphere is depressed boiling point-78.52 ℃, solidfying point-56.6 ℃, critical temperature-31 ℃.The liquid CO 2 fully feasible and good cooling results of distillation of lowering the temperature in water, speed is fast.Refrigerant can also be selected liquid nitrogen for use, fluorine Lyons, methane, butane etc.

The utility model is because the cryogen vessel aie escape valve is arranged in beverage liquid, when opening aie escape valve, the liquid carbon dioxide refrigerant is sprayed by aie escape valve under internal pressure, passing the beverage layer absorbs outside heat distillation the becoming bubble emersion jar, compare by wall of container heat absorption with prior art that to have a beverage rate of cooling fast, chilling temperature is even, the characteristics that the refrigerant consumption is few, and be partly dissolved in the beverage because of carbon dioxide in the sublimation process of liquid carbon dioxide refrigerant in jar, can save the carbon-dioxide technology of beverage gases dissolved under pressure in the beverage production process, directly make this beverage become soda.

Further specify content of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the running condition figure of Fig. 1.

Fig. 3 is the structural representation of another embodiment of the utility model.

Among the figure: 1, pop-top can tank; 2, pop can capping; 3, pop can draws lid; 4, jar interior beverage; 5, the container of storage refrigerant; 6, liquid carbon dioxide refrigerant; 7, container aie escape valve; 8, backguy; 9, end jar.

Among the embodiment as shown in Figure 1, the utility model comprises: pop-top can tank 1, the pop can capping 2 of closed tank 1, be positioned at pop can in the capping 2 draw cover 3 and jar beverage 4 and upper end be fixed on the container 5 of the storage refrigerant of pop can capping 2 belows, container 5 internal memory contain liquid carbon dioxide refrigerants 6, the lower end of container 5 is provided with container aie escape valve 7, and the container aie escape valve is arranged in a jar beverage liquid.One backguy 8 of container aie escape valve captive joint, the other end of backguy 8 and pop can are drawn and are covered 3 and captive joint.Container aie escape valve 7 of the present utility model can adopt existing technical products larynx pressure type valve.For safety, be printed on " rice " font superpressure safety blasting relief port in a pop can capping or a jar base pressure.

In the enforcement as shown in Figure 3, the utility model comprises: pop-top can tank 1, the pop can capping 2 of closed tank 1, being positioned at pop can in the capping 2 draws and covers 3 and a jar beverage 4, jar 9 at the bottom of be provided with at the bottom of the pop can jar one, end jar 9 internal memory contain liquid carbon dioxide refrigerants 6, tank top, the end is provided with aie escape valve 7, one backguy 8 of aie escape valve 7 captive joints, the other end of backguy 8 and pop can are drawn and are covered 3 and captive joint.Aie escape valve 7 adopts existing technical products larynx pressure type valve, and a capping or a jar base pressure are printed on " rice " font superpressure safety blasting relief port.

Production process of the present utility model: in the process of manufacturing self-chilling beverage, can remove the beverage carbon-dioxide production technology of gases dissolved under pressure in advance in the original production process from, and after adopting the direct tinning of beverage, to put into jar with the refrigerant storage container that the pop can capping is fixed together, gland packing, other production technology is constant.The self-cooled easy open can beverage is in the process of its refrigeration of uncapping, and the carbon dioxide that is produced is nontoxic, tasteless, can not burn can not explode harmless (daily carbonated drink of drinking and soda all are dissolved with carbon dioxide).The utility model is applicable to various canned, bottled carbonated beverages and carbonated drink.
