6 is a cross-sectional view taken along the line I-I of the thermal reaction pack unit of FIG.

As shown in FIG. 1, the reaction liquid bag 210 according to the first embodiment of the present invention is sealed in a reaction liquid causing a chemical reaction with the reactant. Here, for heating, the reaction liquid is, for example, 5 to 20% NaCl aqueous solution is used. The reaction liquid bag 210 is fixed to the inside of the first pack 200, the fixed edge portion 214 of which will be described later. The fixed edge portion 214 of the reaction liquid bag 210 has a tearing strap 215 formed by a pair of

incision lines

216a and 216b which are cut by a predetermined cutting length toward the reaction liquid encapsulated at a mutually incision interval. Have Here, the pair of

cut lines

216a and 216b have different cut lengths, respectively. In other words, the incision 216a is longer than the other incision 216b. It is also possible to make the incision 216b longer than the other incision 216a. In addition, although not shown, it is also possible to form the perforated cut line by the longer length of the long cut line 216a. Moreover, it is also possible to form the part which is not cut | disconnected by the perforation line | wire.

A tearing member 211 is connected to the tearing strap 215. The tearing member 211 is inserted into, for example, the opening 213-3 in which the “T” shaped end 212 is formed in the tearing strap 215. Of course, the tearing member 211 can also be fixed to the tearing strap 215 by an adhesive. In this state, when the tearing strap 215 is folded toward the center reaction liquid, the tearing member 211 extends toward the opposite side of the fixed edge portion 214. Pulling the tearing member 211, because one incision line 216b is shorter than the other incision line 216a, the incision line 216b starts the extension incision first. Here, the resistance to the pulling of the tearing member 211 is relatively small because the extended incision of one incision 216b proceeds first. As a result, the pulling acceleration of the tearing member 211 is increased, so that the remaining portion that is not cut can be easily cut. That is, even if the extended incision of the incision 216b proceeds to the end of the other incision 216a and simultaneously incise both of the pair of

incisions

216a and 216b, the tearing strap 215 by the increased pulling acceleration of the tearing member 211. Can be torn easily from the fixed edge 214.

2 is a perspective view showing the configuration of a reaction liquid bag according to a second embodiment of the present invention.

As shown in FIG. 2, the fixed edge portion 514 of the reaction liquid bag 510 is formed by a pair of

incision lines

516a and 516b which are cut by a predetermined cutting length toward the reaction liquid encapsulated therebetween with an incision interval therebetween. Has a tearing strap 515. Here, the pair of

cut lines

516a and 516b have different cut lengths, respectively. In other words, incision 516a is longer than other incisions 516b. At this time, the short cut line 516b includes an inclined cut portion 517b inclined toward the other cut line 516a. Of course, it is also possible to make the other incision 516a shorter than the incision 516b and then incline its end toward the incision 516b. In addition, although not shown, it is also possible to cut the end of the long cut line 516a inclined toward the short cut line 516b. In addition, although not shown, it is also possible to form the inclined cutout 517b which advances toward the long cut line 516a by a perforated cut line. Moreover, it is also possible to form the part which is not cut | disconnected by the perforation line | wire.

When the tearing member 511 is pulled out, the inclined cut line 517b of the cut line 516b starts to extend the cut first. Here, since the extension incision of one incision line 517b proceeds first, the resistance to the pulling of the tearing member 511 is small. In particular, since the incision of the inclined cut line 517b proceeds in the inclined direction, the cutting width of the tearing strap 515 torn is gradually narrowed, so that the resistance to the pulling of the tearing member 511 is further reduced. Therefore, the pulling acceleration of the tearing member 511 is increased, so that the remaining portion that is not cut can be easily cut. That is, even if the incision of the incision 516b extends to the end of the other incision 516a and simultaneously incise both of the pair of

incisions

516a and 516b, the tearing strap 515 is reduced by the reduced pull resistance of the tearing member 511. It can be torn easily from the fixed edge 514.

Figure 3 is a perspective view showing the configuration of the reaction liquid bag according to a third embodiment of the present invention.

As shown in FIG. 3, the fixed edge portion 514 of the reaction liquid bag 510 is formed by a pair of

incisions

516a and 516b which are cut by a predetermined incision length toward the reaction liquid encapsulated therebetween with an incision interval therebetween. Has a strap 515. Here, the pair of

incisions

516a and 516b have different incision lengths, respectively. In other words, incision 516a is longer than other incisions 516b. In addition, the pair of

incisions

516a and 516b includes

inclined incisions

517a and 517b, respectively, inclined toward each other. Although not shown in the drawings, at least one of the

inclined cutouts

517a and 517b may be formed by a perforated cut line. Moreover, it is also possible to form the part which is not cut | disconnected by the perforation line | wire.

When the tearing member 511 is pulled out, the inclined cut line 517b of the cut line 516b starts to extend the cut first. Here, since the extension incision of one incision line 517b proceeds first, the resistance to the pulling of the tearing member 511 is small. In particular, since the incision of the inclined cut line 517b proceeds in the inclined direction, the cutting width of the tearing strap 515 torn is gradually narrowed, so that the resistance to the pulling of the tearing member 511 is further reduced. Further, when the incision of the inclined incision 517b is extended and reaches the same line as the other incision incision 517a, when the pair of

inclination incisions

517a and 517b starts the incision at the same time, the cutting width of the tearing strap 515 is narrower. Lose. Therefore, the pulling acceleration of the tearing member 511 is increased, so that the remaining portion that is not cut can be easily cut. That is, even if the incision of the incision 516b extends to the end of the other incision 516a and simultaneously incise both of the pair of

incisions

4 and 5 are a perspective view and an exploded perspective view of a thermal reaction pack unit according to a fourth embodiment of the present invention, respectively.

As shown in FIG. 4, the thermal reaction pack unit 100 according to the preferred embodiment of the present invention may be connected to the first pack 200 and the second pack 300, and the first pack 200 and the second pack 200. It is provided between the pack 300, the food containing portion 400 is accommodated.

The first pack 200 accommodates a reaction liquid bag 210 in which a reaction liquid is stored, and a reactant 220 that generates heat by reacting with the reaction liquid.

The reaction liquid bag 210 is fixed to the inside of the first pack 200, the fixed edge portion 214 of which will be described later. The fixed edge portion 214 of the reaction liquid bag 210 has a tearing strap 215 formed by a pair of

incision lines

216a and 216b which are cut by a predetermined cutting length toward the reaction liquid encapsulated at a mutually incision interval. Have The tearing strap 215 is disposed to be shifted to one side from the center of the fixed edge 214. This mitigates pulling the

edges

207 and 208 of the first pack 200 to which the fixed edge 214 of the reaction liquid bag 210 is fixed together when pulling the tearing member 211.

As shown in FIG. 5, the fixed edge portion 214 of the reaction liquid bag 210 is provided with coupling through holes 213-1 and 213-2 to facilitate coupling with the first pack 200. Coupling through-hole 213-1 is formed long through the extension direction of the fixed edge. Here, the reaction liquid bag 210 is composed of a packaging material composed of a plurality of layers is provided so as not to be easily damaged by an external impact. Among these packaging materials, it is preferable to include linear-low density polyethylene (LLDPE), which has a shock-absorbing property and is thermally bonded, to facilitate adhesion and increase adhesive strength when combined with the first pack bag 201. .

Coupling through holes 213-1 and 213-2 are provided at the fixed edge 214 to bond the inner cover 203 and the outer cover 201 of the first pack 200 to accommodate the reaction liquid bag 210. To facilitate. That is, as shown in Figure 4, when the inner cover 203 and the outer cover 201 of the first pack 200, the inner cover 203 through the coupling through holes (213-1, 213-2) Since the outer cover 201 is bonded while being in direct contact with each other, the adhesion efficiency increases, and after adhesion, the inner cover 203 and the outer cover 201 may be prevented from being separated from each other by external force. In addition, the coupling through holes 213-1 and 213-2 are interposed between the inner cover 203 and the outer cover 201, and are bonded together with the inner cover 203 and the outer cover 201, so that the first pack 200 is closed. The position is fixed in the Accordingly, even if the tearing strap 215 of the reaction liquid bag 210 is torn by pulling the tearing member 211, the position of the reaction liquid bag 210 is kept constant. The size and number of coupling through holes 213-1 and 213-2 may be variously provided according to the size, thickness, material, etc. of the first pack 200, and a plurality of coupling holes 213-1 and 213-2 may be provided for adhesion efficiency.

On the other hand, the reaction liquid bag 210 and the reaction material 220 are coupled to each other by a predetermined bonding method. This is because the position of the reactant 220 is fixed when the reaction liquid is ejected from the reaction liquid bag 210 by the tearing member 211 to widen the reaction area and extend the reaction time. Here, as for the method of bonding the reaction liquid bag 210 and the reactant 220, various conventional bonding methods may be used according to the material of the reaction liquid bag 210 and the material of the nonwoven fabric accommodating the reactant 220. Preferred embodiments of the invention are bound by hot melt.

The reactant 220 is made of a mixture of magnesium (Mg), iron (Fe), etc., and generates or absorbs heat by a chemical reaction upon contact with the reaction liquid. The reactant 220 is accommodated in a nonwoven fabric divided into a predetermined area so that the same heat is generated or absorbed within a predetermined area when reacting with the reaction liquid. The nonwoven fabric 221 absorbs the reaction liquid during the reaction of the reactant 220 and the reaction liquid, maintains the reaction rate constant, and extends the reaction time to generate or absorb heat for a long time. As shown in FIG. 4, the first pack 200 includes an outer cover 201 and an inner cover 203. The outer cover 201 and the inner cover 203 are made of a material that can be bonded to each other and are bonded by a predetermined bonding method to form a space for receiving the reaction liquid bag 210 and the reaction material 220.

The outer cover 201 and the inner cover 203 may be made of a single layer of material or may be provided of a material made of a plurality of layers, and the plurality of layers of the outer cover 201 and the inner cover 203 may be used to protect the contents from external shocks. And the material forming the outer cover 201 and the inner cover 203 is preferably provided with a property of being bonded by heat can increase the coupling efficiency when the mutual coupling.

Here, the outer cover 201 and the inner cover 203 may be mutually bonded by a method such as thermal fusion, ultrasonic fusion, high frequency fusion, and an adhesive. At this time, the outer cover 201 and the inner cover 203 is the first coupling portion (209-1, 209-2) corresponding to the coupling through holes (213-1, 213-2) of the reaction liquid bag 210 And second coupling portions 205-1 and 205-2, respectively. At this time, when the heat is applied to the first coupling portion (209-1, 209-2) and the second coupling portion (205-1, 205-2) with the coupling through holes (213-1, 213-2) between the outer cover The 201 and the inner cover 203 and the reaction liquid bag 210 interposed therebetween are fused and easily coupled.

As shown in FIG. 5, the second pack 300 has the same configuration as that of the first pack 200 except for the reaction liquid bag. The second pack 300 cannot react by itself because only the reactant 320 is present. Accordingly, as shown in FIG. 8, communication holes 413-1 and 413-2 communicating with the first pack 200 and the third pack 300 to use the reaction liquid of the first pack 200. Is formed. Except for this difference, since the first pack 200 has the same configuration, duplicate description is omitted.

Hereinafter, a method of manufacturing the thermal reaction pack unit 100 according to the present invention will be described with reference to FIGS. 4 to 6.

First, coupling holes 213-1 and 213-2 and openings 213-3 are formed by using a punching machine in the fixed edge portion 214 of the reaction liquid bag 210 in which the reaction liquid is stored. A pair of

incision lines

216a and 216b are formed in the fixed edge portion 214 with different incision lengths around the opening 213-3. The T-shaped end portion 212 of the tearing member 211 is inserted into the opening 213-3 from the lower side to the upper side. Thereafter, the tearing strap 215 formed by the pair of

incisions

216a and 216b is folded to extend the tearing member 211 toward the edge opposite to the fixed edge 214. Then, hot melt is applied to one side of the reaction liquid bag 210 and fixedly coupled to the nonwoven fabric 221 surrounding the reaction material 220. Then, the positions of the outer cover 201 and the inner cover 203 of the first pack 200 correspond to each other, and a predetermined sealer is provided between the reaction liquid bag 210 and the reactant material 220 therebetween. To combine the

edges

At this time, the coupling through-holes 213-1 and 213-2 of the reaction liquid bag 210 are interposed between the outer cover 201 and the inner cover 203, and coupling through-holes 213-1 and 213-. The outer cover 201 and the inner cover 203 are directly bonded to each other through 2). As a result, the outer cover 201 and the inner cover 203 are directly coupled to each other so that the coupling efficiency is enhanced, so that they are not easily separated by an external force.

The first pack 200 and the second pack 300 are sealed by sealing the

edges

208 and 308 of the

inner covers

203 and 303 of the first pack 200 and the second pack 300 thus prepared by a sealer. Combine them. At this time, the predetermined lengths of the lower ends of the

edge portions

208 and 308 are maintained in the free end state without being bonded to each other. This is to ensure a free space at the exit of the food accommodation portion 400 to facilitate the user when entering and exiting food.

The method of using the thermal reaction pack unit 100 according to the present invention manufactured as described above will be described with reference to FIGS. 4 to 6.

And pulling the tearing member 211 exposed to the opening. At this time, the reaction liquid bag 210 is torn by the tearing member 211 and the reaction liquid is ejected into the first pack 200 and reacts with the reactant 220 to generate heat. The ejected reaction liquid flows into the third pack 300 through the communication holes 413-1 and 413-2 and reacts with the second reactant 320. The food contained in the food container 400 is heated by the heat generated by the

packs

200 and 300. As described above, the tearing strap 215 is further made by varying the incision lengths of the

incision lines
