Abstract

In the present invention, the liquid contents are contained in a container (cans, bottles, etc.) and are hermetically sealed, whereby a refrigerant is put together with the liquid contents in the container and the container is sealed while a constant pressure is applied.

The effects of the present invention having such a configuration are as follows.

Opening the container lid of the present invention, the pressure in the container is lowered and then the refrigerant in the container is vaporized directly absorbs the heat of vaporization from the liquid content to enable rapid cooling, the structure is simple, the manufacturing cost is low and the cooling rate is very fast, Cooling is automatically performed when the container is opened, which makes it easy to use.

The present invention relates to a method and apparatus for self-cooling a product in which a liquid content is contained in a container, such as a can product or a bottle product.

The cooling of liquid contents products contained in conventional cans, bottles or cartons of containers is realized by storing them in an external refrigerator or a refrigerated showcase. However, this conventional method has a disadvantage that can not be carried out in places such as outdoors or in the mountains, that is, without a refrigerator.

In order to solve this drawback, the proposed prior art is configured by forming a space portion of a bottom portion of a can container, installing a refrigerant storage container containing a refrigerant in the space portion, and using the refrigerant in the refrigerant storage container into the space portion. By ejecting, the refrigerant was vaporized while depressurizing in the space, and the bottom of the can was cooled by vaporization heat absorption at this time, thereby cooling the liquid contents in the can.

However, a disadvantage of this conventionally proposed technique is that the temperature of the liquid content is lowered from the bottom due to the difference and load at the bottom of the can, which is outside the can. Therefore, since the liquid content is cooler than the upper part, convection cannot occur in the liquid content. In addition, since the outside of the container absorbs heat indirectly through the can, there is a disadvantage in that the heat absorption efficiency is lowered.

In addition, when the pressure in the space portion formed on the bottom of the can acting as an evaporator increases the pressure due to the vaporization of the refrigerant, the evaporation rate of the refrigerant is lowered and eventually the cooling rate is lowered. The present invention devised to solve the shortcomings of the prior art is characterized in that the cooling rate is very fast and the cooling efficiency is increased, as well as the structure is very simple, and the manufacturing cost is inexpensive. same.

Example 1

This embodiment is completed by putting the liquid contents 2 in the container 1 and also putting the refrigerant 3 which is harmless to the human body, and sealing the container in a constant pressure state.

Here, the refrigerant 3 is harmless to the human body, and vaporization is possible at a temperature of approximately 0 C subgroup in an atmospheric pressure state, and at a pressure P in a sealed vessel, the refrigerant 3 in the vessel 1 at a normal temperature around the vessel It is a matter of course that the present invention constitutes a refrigerant 3 having a physical property that does not vaporize.

The cooling method of this embodiment is a direct endothermic cooling method in which the refrigerant 3 in the liquid content 2 absorbs heat directly from the liquid content 2 when vaporizing. Therefore, it is characterized by a very simple configuration that does not require a separate structure other than the refrigerant (3) is directly put into the container. The effect of this embodiment is as follows.

In the case of a bottle or a bottle to open the liquid contents, opening the lid of the bottle causes the pressure (P) in the container (1) to immediately drop to atmospheric pressure, so that the refrigerant (3) in the liquid contents (2) immediately vaporizes. In this case, a large amount of heat of vaporization is directly absorbed from the liquid contents 2 so that the temperature of the liquid contents 2 in the container is lowered in a short time. As a result, the refrigerant 3 is all evaporated and only the liquid content 2 remains in the container 1.

The present embodiment has the advantage that the structure is very simple and the manufacturing cost is very low, and also the cooling rate is very fast compared to the prior art.

In addition, if the lid of the container 1 is opened without a separate operation for ejecting the coolant 3, there is also a convenience in use in which cooling is automatically started while the coolant 3 is automatically vaporized.

Therefore, this embodiment is a direct cooling method for directly cooling the liquid contents (2)

Therefore, the configuration of the present invention is as described above is configured to seal the refrigerant (3) together with the liquid contents (2) in a container at a predetermined pressure (P) state.

Therefore, the present invention is a very convenient invention that allows you to drink cold beer or beverages even where there is no refrigerator.

In the production of the present invention, the injection of the refrigerant is provided with a refrigerant injection pipe (not shown) in the container 1 through which the refrigerant is pushed to a predetermined pressure through which the refrigerant injection pipe (not shown) is sealed. Alternatively, or alternatively, after the temperature of the liquid contents 2 is lowered below the vaporization temperature of the refrigerant 3, the refrigerant 3 and the liquid contents 2 are injected together into the vessel 1, and then the vessel ( It can be carried out by sealing the 1). At this time, the process of sealing the lid of the can or the lid of the bottle is to be carried out under the ambient temperature and pressure conditions that the refrigerant (3) does not vaporize.
