A beverage can with an automatic refrigeration device

Abstract

The invention discloses a beverage can with an automatic refrigerating device. The beverage can comprises an outer can, wherein the outer can comprises a can body, a top cover and a bottom cover; a reaction device is arranged in the outer can; the reaction device comprises a reaction cup and a solvent cup arranged in the reaction cup; a refrigerant is loaded in the reaction cup; a dissolving agent is loaded in the solvent cup; the cup mouth of the reaction cup is in sealed fit with the bottom cover; a sealing film is arranged at the cup mouth of the solvent cup; the bottom of the solvent cup is arranged on the bottom cover; a guide groove is formed in the inner side of the bottom of the solvent cup; an ejector rod is inserted in the guide groove; the bottom end of the ejector rod is inserted in the guide groove in the bottom of the solvent cup; the top of the ejector rod faces the sealing film; a sharp bulge is arranged at the top end of the ejector rod; the refrigerant consists of NH4NO3, NaCO3.10H2O and CO(NH2)2; the dissolving agent is a NaCl solution. The beverage can has good leakproofness and a good refrigerating effect.

Description

technical field [0001] The invention relates to a beverage can, in particular to a beverage can with an automatic refrigeration device. Background technique [0002] Beverage cans have always occupied a large proportion in the beverage packaging industry. With the development of the times, beverage cans are developing in the direction of high-grade, multi-variety, and deep processing that adapt to the international trend. Therefore, many new special beverage can packaging have come out one after another. In the existing beverage can technology, the beverage can itself has no automatic cooling function. In the hot summer, it can only be cooled by external refrigeration, such as putting it in the refrigerator to get cold drinks. For outdoor consumers, they can get it anytime, anywhere. Drinks at the right temperature have become an urgent desire, and the idea that people can drink cold and refreshing drinks no matter when and where has always been the goal of research in the b...

AI Technical Summary

Problems solved by technology

The sealing ring a9 is used to seal between the ejector rod a8 and the penetrating surface of the reaction tank a4 to prevent the solvent in the lower layer a42 of the reaction tank from leaking through the gap between the penetrating surfaces. There is a gap between the ejector rod a8 and the penetrating surface of the reaction tank a4, although the sealing ring a9 is also used to seal, but the sealing effect is not good, and the dissolving agent will still leak through the gap between the penetrating surface, so that the dissolving agent is in the It leaks before the user uses it, but it does not achieve the cooling effect when it is actually used

[0006] In addition, due to the high ductility of the film a62 when it is stressed, the push rod a8 is directly pushed by the bottom a7 of the tank body. The stroke required for the push rod a8 to pierce the film a62 exceeds the deformable range of the bottom a7 of the tank body, so the top will appear. The situation that the rod a8 cannot pierce the film a62, so that the refrigerant and the solvent cannot be mixed to achieve refrigeration

[0007] (2) The refrigeration effect of the refrigerant is poor

[0012] But the refrigerant refrigeration effect disclosed in this patent is poor, and refrigeration time is short

At the same time, because the refrigerant absorbs heat through a chemical reaction to achieve the purpose of refrigeration, the reaction process itself will neutralize a part of the temperature, which further reduces the refrigeration effect and refrigeration time of the refrigerant, seriously affecting the popularization and use of the refrigerant.
