The present invention relates to a thermal insulation and cold storage container of a beverage, and more particularly, a heat storage unit and a heat insulation unit are formed in a wall or a bottom of a thermos, a kettle, a cup, etc., which can store a certain amount of the beverage therein, for a long time. It relates to a container that can keep warm or cool.

In general, a thermos bottle is most commonly used among beverage storage apparatuses for portable storage of hot or cold beverages.

Conventional thermos is composed of a cylindrical body formed with a storage unit for storing the beverage therein, and a cap for opening and closing the inlet of the body. The main body includes an inner container for storing contents, and an outer container configured to surround the inner container at a predetermined interval from the outer surface of the inner container, and a stopper part is configured to allow the contents to flow in and out of the inner container from the outside.

The thermos configured as described above is to maintain a vacuum between the inner container and the outer container to maintain the storage temperature of the contents stored inside the inner container. A discharge hole is formed at the bottom of the outer container, and a vacuum is formed between the inner container and the outer container through the discharge hole.

That is, by combining the exhaust pipe connected to the vacuum means for suctioning and discharging the air to the discharge hole, and discharges the air between the inner container and the outer container through the exhaust pipe and the vacuum means to make a vacuum state and pressurizing the discharge hole It is sealed by sealing through welding process. After sealing the outlet hole, a separate lower cover is placed on the lower part to protect the outer container and to be seated at the same time.

In this way, the thermos obtains a warming effect by forming a vacuum layer having a suitable gap around the inner container to prevent the temperature of the storage stored in the inner container from being transferred to the outside.

However, the conventional thermos blocks the heat conduction phenomenon of the air by the vacuum layer or suppresses heat exchange with the outside by the insulating member, and only slows down the rate at which the heated water drops to room temperature. There is a problem that can not be sustained for a certain time.

The present invention has been made to improve the above problems, and an object thereof is to provide a heat or cold container in which a beverage can be maintained at a constant temperature for a predetermined time by using a heat storage material that stores thermal energy by phase change. .

Another object of the present invention is to form a wall or floor in a triple wall structure to fill the heat storage material in the inner space to absorb or release a certain amount of heat, and to form a vacuum layer in the outer space to block heat exchange with the outside The present invention provides a container having excellent heat retention or cold storage efficiency.

Insulating and cold storage container of the beverage of the present invention for achieving the above object is provided with a body for storing the beverage for keeping warm or cold inside, wherein the wall or bottom of the body is the first and the second layer is arranged from the inner layer And a heat storage unit filled with a second wall and a phase change material for storing thermal energy by phase change between the first wall and the second wall.

The main body further includes a third wall formed on the outside of the second wall and the first and second walls and the layer layer is arranged, and the heat insulating portion formed of a vacuum layer between the second wall and the third wall. It features.

The main body further comprises a heat insulating cover surrounding the wall from the outside to block heat exchange.

And a lid coupled to an upper portion of the main body in which the inlet and outlet of the drink is formed to open and close the inlet.

As described above, according to the insulating and cold storage container of the beverage of the present invention, the PMM, which is a heat storage material that stores thermal energy by phase change, releases heat to the beverage or absorbs heat from the beverage, thereby heating or cooling the beverage for a long time. Can be maintained.

In addition, by forming a heat insulating portion of the vacuum layer on the outer side of the heat storage portion made of the heat storage material, it is possible to prevent heat transfer from the heat storage portion to the outside to greatly improve the thermal insulation or cold storage efficiency of the beverage.

Hereinafter, with reference to the accompanying drawings will be described in detail the heat retention and cold storage container of a beverage according to a preferred embodiment of the present invention.

1 is a partially cutaway perspective view showing a warm and cold container of a beverage according to an embodiment of the present invention, Figure 2 is a cross-sectional view of the main body applied to Figure 1, Figure 3 of the beverage according to another embodiment of the present invention 4 is a cross-sectional view of the warm and cold storage container, and FIG. 4 is a cross-sectional view of the warm and cold storage container of a beverage according to another embodiment of the present invention.

1 and 2, the heat and cold container of the present invention is to heat or cool the water stored therein by heating to a predetermined temperature or cooled to a predetermined temperature. In the present embodiment, for the convenience of description, a thermal insulation container for insulating water will be described as an example.

The thermal insulation container of this invention is largely provided with the main body 5, the fastener 51, and the lid 55. As shown in FIG.

The main body 5 has a storage space formed so that a predetermined amount of water can be stored therein and has a cylindrical shape with an open top. Water flows in or out through the inlet formed at the top. The main body 5 includes a bottom 41, a wall 10 formed at a predetermined height on the floor 41, and a coupling part 45 formed at an upper portion of the wall 10 to provide an inlet. Threads are formed on the inner side and the outer side of the wall on which the coupling part 45 is formed, the inner plug 51 is screwed on the inside, and the lid 55 is screwed on the outside to open and close the inlet.

The wall 10 consists of triple walls. The first, second, and third walls 11, 21, 31 are formed in the order of traveling from the inner side to the outer side. The first, second, and third walls 11, 21, 31 are arranged concentrically about a storage space in which water is stored. Therefore, a constant space is formed between the first and second walls 11 and 21 and between the second and third walls 21 and 31.

In this triple wall structure, the second wall 21 is disposed inside the third wall 31, and the first and second walls are disposed after the first wall 11 is disposed inside the second wall 21. The upper part of the third walls 11, 21 and 31 may be combined to be formed, but the present invention is not limited thereto, and the first, second and third walls 11, 21 and 31 may be spaced apart from each other by a predetermined interval. Any structure can be used as long as it can form a structure.

The first, second, and third walls 11, 21, and 31 that form the wall 10 extend to the bottom, so that the bottom 41 of the main body 5 is similar to the wall 10. It is formed into a middle wall structure. Unlike the illustrated example, the main body 5 may be formed of only a wall 10 in a triple wall structure or only a bottom 41 in a triple wall structure.

A heat storage unit 15 filled with a heat storage material is formed between the first wall 11 and the second wall 21 of the main body. The heat storage material is heated to a temperature higher than room temperature to accumulate heat in the material itself, and then releases heat to the beverage stored inside the main body 5 so that the beverage can be maintained at a constant temperature for a predetermined time. It is preferable to use a phase change material (PCM, hereinafter referred to as PCM) that stores thermal energy by phase change as the heat storage material.

PCM absorbs or releases latent heat in an isothermal state upon phase change between a solid state and a liquid state. Because of this phase change, the PC storing thermal energy absorbs or releases latent heat and thus can store more thermal energy than ordinary heat storage materials. The PCM absorbs and stores heat when it rises above the phase change temperature, that is, the melting point, and maintains a constant temperature by releasing stored heat when the temperature falls below the melting point.

PCM may be used for cold storage when the phase change temperature is below 20 ° C., and may be used for thermal insulation when the phase change temperature is about 60 ° C. or higher. For example, when the PM 15 having a phase change temperature at 80 ° C. is charged in the heat storage unit 15, if 100 ° C. water is stored inside the main body 5, the initial solid state PCM absorbs heat from the water. Phase changes into a liquid state. When the water slowly cools down to about 80 ℃, it releases heat to prevent water from falling below 80 ℃, keeping the water warm for a long time.

Conventional PCM may be used in the present invention, and paraffin-based material is used as an example. More specifically, hexadecane and octadecane may be used, and various types of paraffinic materials may be mixed and used. The PCM is injected through an injection hole (not shown) formed in the upper portion of the second wall 21 and then sealed by pressure fusion.

In addition, between the second wall 21 and the third wall 31, a heat insulating part 25 formed of a vacuum layer is provided to prevent heat from being transferred to the outside through the second wall. The heat insulating part 25 blocks the heat exchange with the outside to prevent the beverage from cooling quickly. The heat insulating part 25 couples the pipe to a discharge hole (not shown) formed at the bottom of the third wall 31, and the pipe is connected to a vacuum device that sucks and discharges air so that the second wall 21 and the third wall ( 31) is formed by evacuating the air to make a vacuum state and then press-fusion welding the discharge hole.

According to the present invention configured as described above, the temperature of the beverage is maintained at a constant temperature by the heat emitted from the heat storage unit 15, and the thermal insulation unit 25 keeps the beverage for a long time by preventing cooling below a predetermined temperature. Can be. In addition, when storing the cold beverage in the container of the present invention can of course be cooled to a certain temperature for a long time.

On the other hand, in the above-described exception, the main body may have a double wall structure formed of first and second walls, and the first and second walls may be configured to have a heat storage portion filled with PCM.

Although not shown, an insulation cover may be further formed on the outside of the wall 10 to block heat exchange. The heat insulation cover is a structure in which a heat insulating material is formed in a tubular shape and is covered on the outside of the wall 10. As the heat insulating material, polyurethane, artron, polyester, polyethylene, synthrate, propylene, or the like can be used. This insulation cover greatly improves the insulation efficiency of the present invention.

The main body 60 of the illustrated thermal insulation container is formed of a wall 61, a bottom 71, and a lid 57, and a handle 59 is formed outside the main body 60.

The bottom 71 of the thermal insulation container is formed in a double structure formed of first and second walls 73 and 75 on which layers are arranged. PCM is filled between the first and second walls 73 and 75.

4 shows another example of the present invention. Referring to FIG. 4, the present embodiment uses a conventional cup as a heat storage container.

The main body 80 of the illustrated thermal insulation container is formed of a wall 81 and a bottom 89, and a handle 91 is formed outside the main body 80.

The wall 81 and the bottom 89 of the main body are formed in a triple structure formed of the first, second, and third walls 83, 85, and 87 in which the layer layers are arranged. And the heat accumulating part 84 filled with PCM is formed between the 1st and 2nd walls 83 and 85, and the heat insulating part formed by the vacuum layer between the 2nd and 3rd walls 85 and 87. 86 is formed.
