Detailed ways

2-4 are perspective views and sectional views illustrating the structure of the temperature-controlling pouch package 100 according to the first exemplary embodiment of the present invention. As shown in the figure, the temperature-controlled bag-shaped package 100 according to the first exemplary embodiment of the present invention includes a first package 200 and a second package 400, and the first package 200 accommodates therein a reactive fluid. The reaction fluid bag 210 and the reaction material bag 220 for storing the reaction material, the second package 400 is configured to exchange heat with the first package 200, and accommodate the heat absorption between the reaction material and the reaction fluid Items that are cooled and heated by reactive and exothermic reactions. the

The reactive fluid bag 210 stores a reactive fluid that chemically reacts with the reactive material. The reaction fluid can be changed according to endothermic reaction, exothermic reaction and the kind of reaction material. Typically, water is used as the reactive fluid. In the case of an exothermic reaction, an aqueous solution of sodium chloride can be used as the reaction fluid. Also, the reaction fluid may contain an additive for controlling the melting point (freezing point) of the reaction fluid and a catalyst for controlling the reaction rate of the reaction fluid. For example, in the case of an exothermic reaction, magnesium chloride may be added to the reaction fluid (ie, water) to lower the freezing point of the water, thus preventing the reaction fluid from being easily frozen in relatively low temperature regions. the

The reaction fluid bag 210 is provided with a tearing part 211 on one side thereof, so that the reaction fluid flows out of the reaction fluid bag 210 and interacts with the reaction material of the reaction material bag 220 . The tearing part 211 is connected with a cutting member 215a, which is cut from the edge 215 of the reaction fluid bag 210, and when the user pulls the reaction fluid bag 210 outward, the cutting member 215a is torn open. The reactive fluid bag 210 allows the reactive fluid to react with the reactive material. Alternatively, the tearing member 211 shown in FIG. 3 can be replaced by other methods, as long as the tearing member 211 can tear the reaction fluid bag 210 and allow the reaction fluid to react with the reaction material. the

For example, according to an exemplary embodiment of the present invention, the user can tear the reaction fluid bag 210 by simultaneously squeezing the temperature-controlling bag-shaped package 100 on both sides without a separate tearing member 211 , thus causing a chemical reaction. At this time, the edge 215 of the reaction fluid bag 210 can be sealed with a weak force and thus the user can easily tear the reaction fluid bag 210 . the

The reaction fluid bag 210 protects the reaction fluid from damage due to external shocks, and isolates the reaction material from the reaction fluid. The reactive fluid bag 210 is manufactured together with a packaging material having multiple layers. The packaging material may include one of linear low-density polyethylene (LLDPE), nylon (NY), aluminum foil (Al) and easy-cut nylon (easy-cut nylon, EZ.NY). The reactive fluid bag 210 contains a reactive fluid in a reactive fluid storage region 212 and the other regions are heat sealed. the

Meanwhile, the reaction fluid bag 210 can be replaced by any bag as long as the bag can store fluid. the

In order to heat the item, the reactive material uses a heat medium for causing an exothermic reaction with the reactive fluid. For example, the heat medium includes metals such as magnesium and iron, or calcium oxide. the

On the other hand, the reactive material uses a coolant for causing an endothermic reaction with a reactive fluid in order to cool the item. For example, the coolant includes ammonium nitrate, sodium acetate, urea, and the like. In addition, other known compounds that cause an endothermic reaction with the reaction fluid may be used. the

If the reactive material bag 220 stores all the different coolants together, each coolant can be packaged separately to prevent the coolants from interacting with each other. That is, each coolant may be individually packaged with a water-soluble film. the

As shown in FIG. 4 , the first package 200 contains the reaction material bag 220 and the reaction fluid bag 210 , and the first package 200 is configured to exchange heat with the second package 400 . The first package 200 is used to prevent the reaction fluid from leaking when the reaction material reacts with the reaction fluid. At this time, the first package 200 may further include an absorbing member to prevent leakage of the reaction fluid. Tissue paper, nonwoven fabric, sponge, etc. can be used as the absorbent member. the

The second package 400 is connected to an edge area of the first package 200 and forms a storage space S to store items. The second package 400 is sealed in a state where articles are contained therein, or is opened through an opening 410 (see FIG. 2 ) through which articles are put in or taken out. The temperature-controlling pouch package 100 according to an exemplary embodiment of the present invention includes an opening 410 at a lower region thereof, but is not limited thereto. Alternatively, the opening 410 may be provided on the side of the second package 400 if necessary. Also, the opening can be opened/closed by zippers or buttons to reduce heat loss during exothermic or endothermic reactions. the

Meanwhile, the items stored in the second package 400 include one of food, drink, plaster for reducing wound temperature of the wounded, and mask for skin care. the

An example of a method of using the temperature-controlled pouch package 100 having the structure according to the first exemplary embodiment of the present invention is as follows. First, the user tears the notch 205 on the first package 200 to expose the tearing part 211 to the outside. When the tear part 211 is squeezed, the reaction fluid bag 210 is ruptured, and thus the reaction fluid and the reaction material chemically react with each other, thereby causing an endothermic reaction or an exothermic reaction. Correspondingly, the internal temperature of said first package 200 rises or falls, thereby raising or lowering the temperature of the items contained in the second package 400 that is in heat-exchangeable contact with the first package 200. the

As described above, the temperature-controlled bag-shaped package 100 according to an exemplary embodiment of the present invention accommodates items together, and thus is convenient for a user to carry. Also, the heat or cold generated by the chemical reaction between the reactive fluid and the reactive material can be quickly transferred to the second package in contact with the first package, so that the item can quickly reach the desired temperature. the
