The contents heating kit 1 according to the present embodiment includes a pack 10 and a heat pack 100 accommodated in the pack 10.

The pack 10 according to the present exemplary embodiment includes a first pouch 20 and a first opening and closing part 30 as shown in FIGS. 1 and 2.

The first pouch 20 is formed by bonding the first film 20a and the second film 20b to each other. Of course, the first pouch 20 may be composed of only one film in one piece. In the present embodiment, the first film 20a and the second film 20b are bonded to each other except for one side of the edge to form a first accommodating space S1 therein. The opening 21 provides a passage through which the heat pack 100 enters and exits from the first accommodation space S1.

As shown in FIGS. 5 and 6, the first pouch 20 may accommodate at least one other content A and B arranged around the heat pack 100. The first pouch 20 is preferably provided to have a first accommodation space (S1) corresponding to the volume of the other contents (A, B) and the heat pack 100 to be accommodated therein. Here, the other contents A and B are for distinguishing the contents (see C of FIG. 5) contained in the heat pack 100 to be described later. Examples of other contents A and B include side dishes, condiments or sauces. And, as will be described later as an example of the contents (C) accommodated in the heat pack 100 may be cooked food such as rice.

The first pouch 20 may be made of synthetic resin such as PE (polyethylene), PP (polypropylene), and PET. It is preferable that the first pouch 20 does not tear well even to an external impact. The first opening / closing portion 30 is attached to the opening of the first pouch 20.

The first opening / closing part 30 opens and closes the opening 21 of the first pouch 20 while leaving a predetermined opening section O allowing the first receiving space S1 of the first pouch 20 to communicate with the outside. do.

In the present embodiment, the first opening and closing part 30 is provided with zippers 30a and 30b. The first opening and closing part 30 is an arm zipper 30a adhered to the inside of the first film 20a constituting the first pouch 20 along the opening 21 of the first pouch 20, and the second film. It is attached to the inner surface of the (20b) and includes a resin zipper (30b) coupled to the arm zipper (30a). The first opening / closing portion 30 is provided in the entire area of the opening 21 of the first pouch 20. The first opening and closing part 30 opens and closes a section excluding the opening section O among the openings 21 of the first pouch 20.

As shown in FIG. 2, the open section O is formed by not bonding at least one predetermined region of the arm zipper 30a and the resin zipper 30b to the inside of the first pouch 20. Thus, even if the arm zipper 30a and the resin zipper 30b are fastened to each other, the inside and the outside of the first pouch 20 may communicate with each other through the open section O. FIG.

The open section O may be formed between the arm zipper 30a and the first pouch 20, or may be formed between the resin zipper 30b and the first pouch 20. In addition, the open section O may be formed both between the first pouch 20 and the arm zipper 30a, and between the first pouch 20 and the resin pouch 30b. In addition, the opening section O may be formed only in one region along the longitudinal direction of the zippers 30a and 30b, or may be formed in a plurality of regions. The reactor body of the heat pack 100 may be discharged to the outside even when the arm zipper 30a and the resin zipper 30b are fastened through the open section O, which will be described later.

In the pack 10 according to the present exemplary embodiment, a sealing part 25 in which one surface and the other surface of the first pouch 20 are adhered to the outside of the zippers 30a and 30b along the opening 21 to close the opening 21. ) May be further included. Sealing portion 25 is formed on the outer side to the upper portion of the zipper portion (30a, 30b) on the basis of Figure 1 to close the opening (21). The sealing portion 25 has a 'c' shape opening toward the zipper portions 30a and 30b. In other words, the sealing part 25 extends downward from the uppermost region and both edges of the edge portion of the first pouch 20 along the opening O, and has a 'c' shape.

A cutting groove 27 may be formed at at least one side of the sealing portion 25 to facilitate the cutting of the sealing portion 25 from the first pouch 20. Thus, even when the opening section O is formed in the opening 21 of the first pouch 20, it is possible to prevent foreign substances such as dust and water from entering the first pouch 20 from the outside. Here, after the user cuts and removes the sealing portion 25 from the first pouch 20 along the cutting groove 27, the user can operate the first opening / closing portion 30 to open and close the opening.

Meanwhile, as shown in FIG. 8, the open section O may be formed by continuously installing the female zipper 30a and the resin zipper 30b, but shorter than the opening 21.

In addition, the open section O may be formed by discontinuously providing at least one of the arm zipper 30a and the resin zipper 30b along the opening 21. In other words, the open section O may be formed by discontinuously providing the arm zipper 30a along the opening 21, or by forming the resin zipper 30b discontinuously along the opening 21. As shown in FIG. 9, both the female zipper 30a and the resin zipper 30b may be formed discontinuously along the opening 21.

In addition, the open section O may be formed by providing different lengths of the arm zipper 30a and the resin zipper 30b along the opening 21 of the first pouch 20.

3 and 6, the heat pack 100 includes a second pouch 110 having an opening 115 communicating with the second receiving space S2 and the second receiving space S2 therein. And a partition 120 disposed in the pouch 110 to partition the second accommodation space S2 into the contents accommodation space S3 and the heating spaces S4 and S5 in which exothermic reactions occur, and the heating spaces S4 and S5. And a heat generating part 130 accommodated in the heat generating reaction.

Here, in this embodiment, it will be described as an example that the heating space is divided into two plurality of heating space (S4, S5).

The second pouch 110 includes a first film 111 and a second film 112 forming the second accommodation space S2 and the opening 115.

The contents C, which are input or taken out through the opening 115, are accommodated in the contents accommodation space S3.

On the other hand, the partition unit 120 divides the heat generating spaces S4 and S5 into the first heat generating space S4 and the second heat generating space S5 and the first partition member 121 and the second compartment member 123. Include.

The partition unit 120 allows the reactive gas (steam or steam) generated by the exothermic reaction in the exothermic spaces S4 and S5 to flow into the contents receiving space S3 from the exothermic spaces S4 and S5.

The partition unit 120 may include a reactor body inlet opening 122 provided to introduce the reactor body into the contents accommodation space S3.

In some cases, the reactor inlet opening 122 may be omitted. For example, when the compartment 120 is made of a material that transmits only gas and not liquid, it may not be necessary to form a separate inlet opening 122. In this case, a non-woven fabric made of polypropylene may be used as an example of the partition 120 that transmits only gas and not liquid.

Here, experiments were carried out on the permeability of the reaction liquid by the nonwoven fabric made of polypropylene and the reaction liquid by the exothermic reaction. According to the test results, it is preferable that the basis weight (g / m 2) of the nonwoven fabric made of polypropylene has a range of about 70 or more and 110 or less. As a result of four repeated tests, non-woven fabric having a basis weight (g / m 2) of less than 70 was detected that water, which is a reaction liquid, passed through the nonwoven fabric at least once. Therefore, it is preferable to use a nonwoven fabric having a basis weight of 70 or more in that the liquid impermeability can be ensured with high reliability. When the reaction liquid is delivered to the contents (C), the user may be burned in the process of taking out the contents (C) from the accommodation space (S3).

In addition, in the case of a nonwoven fabric having a basis weight (g / ㎡) of more than 110, it was confirmed that the degree of permeation of the reactor body is drastically reduced, which hinders the smooth discharge of the reactor body. Therefore, it is preferable to use a nonwoven fabric having a basis weight (g / m 2) of 110 or less from the viewpoint of smoothly discharging the reactor body.

Here, the reactor inlet opening 122 may be formed by leaving one end of the first compartment member 121 and the second compartment member 122 at the free end without sealing the second pouch 100. Of course, in some cases, the reactor body inlet opening 122 may be provided by forming an opening in one partition member instead of a plurality of partition members.

In addition, the partition unit 120 may further include a reactor body passage member 125 disposed in the reactor body inlet opening 122.

In some cases, the reactor passage member 125 may be omitted. For example, when exothermic reactions occur in the exothermic spaces S4 and S5, the reaction liquid is located below the exothermic spaces S4 and S5 because of its own weight. Therefore, since the heat generating pack 100 can be maintained in an upright state as shown in FIGS. 5 and 6, it is almost impossible for the reaction liquid to pass through the reactor inlet opening 122. However, as will be described later, when the heating unit 130 has only one of the heating element and the reaction liquid exothermic reaction with the heating element, it is preferable that the reactor body passage member 125 is formed.

Here, a separate holder (not shown) may be provided to keep the heat pack 100 in an upright state. In some cases, when the first pouch 20 is provided with a heat insulating material, the user may hold the first pouch 20 by hand without a holder and maintain the heating pack 100 therein in a standing state.

On the other hand, the reactor passage member 125 is allowed to enter the reactor body by the exothermic reaction in the exothermic space (S4, S5) into the contents receiving space (S3), but the reaction liquid by the exothermic reaction is the contents receiving space (S3) Inflow into) acts as a deterrent. Here, the term 'inhibit' does not mean that the reaction liquid is prevented from entering 100%, but rather means that the reaction liquid may be introduced into the contents accommodating space S3.

Here, the reactor body passing member 125 may include a breathable nonwoven fabric. In some cases, a nonwoven fabric made of polypropylene having a basis weight in a predetermined range of permeating only the above-described reactive gas may be used.

In addition, when the reaction liquid or the heating element for the exothermic reaction is introduced through the input part 113 to be described later, the reactor passage member 125 easily guides the introduced reaction liquid or the heating element to the exothermic space (S4, S5). It may be provided in an inclined "reverse U" or "reverse V" shape.

In more detail, as illustrated in FIGS. 5 and 6, the reactor passage member 125 is inclined to the first heat generating space S4 and the second heat generating space S5, respectively, based on the center portion. It may be provided to have a "reverse U" or "reverse V" shape. Accordingly, the heating element or the reaction liquid introduced through the input part 113 may be easily guided to the first heat generating space S4 and the second heat generating space S5.

On the other hand, the heat generating unit 130 may include at least one of a heating element and a reaction liquid that causes an exothermic reaction when in contact with each other.

Here, the heating element may include at least one of calcium oxide, calcium hydroxide, magnesium chloride and iron. The heating element may be variously changed in addition to the examples as long as it can exothermicly react with the reaction liquid.

5 and 6 illustrate that the heat generating unit 130 has only a heating element as an example. In some cases, the heating unit 130 may include only a reaction liquid (eg, 'water') instead of the heating element.

As described above, when the heating unit 130 includes only one of the heating element or the reaction liquid, the user may inject the other one through the input unit 113 formed in the second pouch 110 to cause the exothermic reaction to occur. can do.

According to the example shown in Figures 5 and 6, the user may cause an exothermic reaction by injecting water, which is the reaction liquid through the input unit 113.

On the contrary, when the heat generating unit 130 includes only the reaction liquid, the exothermic reaction may be caused by injecting the heating element through the input unit 113.

On the other hand, in another embodiment, the heat generating unit 130 may include both a heating element and a reaction liquid container containing a reaction liquid for exothermic reaction with the heating element. In this case, an exothermic reaction may be caused by the user exerting the reaction liquid out of the reaction liquid container by applying an external force such as breaking the cracker or crushing or tearing the reaction liquid container. In this case, since the heating element or the reaction liquid does not need to be introduced through the input unit 113 to cause the exothermic reaction, the input unit 113 may be omitted.

On the other hand, the second pouch 110 may further include a second opening and closing portion 114 capable of opening and closing the input portion 113.

As shown in FIGS. 5 and 6, the second opening / closing unit 114 may be provided in a zipper form. 5 and 6 is only an example, and the Velcro type or adhesive type, and other known various opening and closing methods may be employed.

Unlike the first opening and closing portion 30, the second opening and closing portion 114 is provided to open and close an entire region of the input portion 113 of the second pouch 110 without an opening section. Here, when the closing part 113 is closed, the second opening and closing part 114 preferably has a high sealing property so that the reactor body does not leak through the input part 113.

In addition, as shown in FIG. 4, when the reaction liquid is introduced into the exothermic spaces S4 and S5 through the input unit 113, the injected reaction liquid is disposed between the first and second heat generating spaces S4 and S5. Communication holes 121a and 123a may be provided at lower side edges of the partition members 121 and 123 so as to be movable.

In some cases, the reaction liquid introduced through the input unit 113 may be concentrated in only one of the plurality of exothermic spaces S4 and S5, but the reaction liquid may communicate with the communication port 121a. , 123a may be flowed into another heating space.

On the other hand, Figure 4 is an exploded perspective view of the contents heating kit 1 according to a preferred embodiment of the present invention described above.

The first film 20a and the second film 20b of the first pouch 20 are sealed along the edge except for a portion to be the opening 21 while receiving the heat generating pack 100 therein. The first opening / closing portion 30 is attached to the opening 21 with the open section O remaining.

The first film 111 and the first compartment member 121 of the second pouch 110 have a first compartment except for a portion to be the reactor inlet opening 122 while accommodating the heat generating unit 130 therein. Sealed along the edge of the member 121.

The second compartment 111 of the second pouch 110 and the second compartment member 123 also receive the heat generating portion 130 therein, except for the portion to be the reactor inlet opening 122, the second compartment member. It is sealed along the edge of 123.

The first film 111 and the second film 112 of the second pouch 110 are sealed only with side edges. As a result, the input part 113 is formed.

The space between the first partition member 121 and the second partition member 122 becomes a content accommodation space S3. The first partition member 121 and the second partition member 122 have an opening 115 for introducing the contents C into the contents accommodating space S3 and the contents in the heat generating spaces S4 and S5 of the reactor body. Sealed with each other so that the reactor body inlet opening 122 for the inlet into the receiving space (S3) is formed. Here, the width of the opening 115 is an unsealed lower section w of the first partition member 121 and the second partition member 122, as shown in FIG. 4.

5 and 6 show the flow of the reactor body with arrows when heating the contents C and the other contents A and B of the contents heating kit 1 of the above-described embodiment.

When an exothermic reaction occurs, a reactive gas is generated in the first and second heat generating spaces S4 and S5.

The generated reactive gas is introduced into the contents receiving space S3 by passing through the reactive gas passage member 125 without being discharged through the input portion 113, since the second opening and closing portion 114 seals the input portion 113. do.

The introduced reactant heats the contents (C). Of course, the contents C are heated by conducting heat generated in the first and second heat generating spaces S4 and S5 adjacent to the left and right. The content (C) can be heated twice by the heat conduction and the reactor body, it is possible to shorten the heating time.

In the figure, the contents receiving space (S3) is wide in the contents (C) it is shown that the contents (C1) and each of the first partition member 121 and the second partition member 123 is in a non-contact state, which is described It is merely exaggerated for convenience. In order for the heat of the heat generating spaces S3 and S4 to easily heat the contents C by the heat conduction, the contact area between the contents C and the first partition member 121 and the second partition member 123 is wide. It is preferable.

The reactor body having passed the contents (C) heats the other contents (A, B) while passing through the other contents (A, B) disposed in the first receiving space (S1) around the heat generating pack (100).

Thereafter, the reactor body is discharged to the outside through the open section (O) formed in the first pouch (20).

Here, it is preferable that the 1st film 20a and the 2nd film 20b of the 1st pouch 20 are heat insulating materials so that the 1st pouch 20 may have heat insulation. In some cases, a coating layer having thermal insulation may be formed on the inner surface or the outer surface of the first film 20a and the second film 20b.

In the above embodiment, a heat pack having a plurality of heat generating spaces S4 and S5 formed therebetween with a content containing space S3 interposed therebetween, but in some cases, a plurality of content containing spaces having a central heat generating space therebetween. It can also be changed to a heat pack having a structure formed.

Next, the contents heating kit 1 'according to another embodiment of the present invention will be described in detail with reference to FIG.

The contents heating kit 1 ′ according to the present embodiment is coupled to the pack 10 and the first pouch 20 according to the above-described embodiment, and the second accommodation space S2 partitioned from the first accommodation space S1. And a second pouch 40 forming '). In the present embodiment, the content to be heated is accommodated in the first accommodating space S1, and the heat generating part 50 is accommodated in the second accommodating space S2 ′. The heating unit 50 is the same as the heating unit 130 according to the above-described embodiment.

The second pouch 40 is formed of one film, and the edge region is adhered to the first film 20a of the first pouch 20 so that the second accommodating space S2 ′ is disposed between the second pouch 40 and the first pouch 20. To form. However, like the first pouch 20, the second pouch 40 may be provided as a pair of films and adhered to the first pouch 20.

As described above, according to the present invention, the opening of the first pouch 20 is left while the predetermined opening section O is allowed to communicate with the outside of the first receiving space S1 of the first pouch 20. By providing the first opening and closing portion 30 to open and close 21, it is possible to easily provide a steam discharge structure that can discharge the steam to the outside when the steam generated by the exothermic reaction in the internal space of the pack 10.

In addition, when the first opening / closing portion 30 closes the opening 21 of the first pouch 20 while leaving only the open section O, the exothermic reaction occurs, and the steam generated by the exothermic reaction opens the opening 21. Since it is discharged through the narrow opening section (O) instead of being immediately discharged to the outside through the steam in the interior of the first pouch (20) for a long time. Thus, the heating efficiency of the contents is improved.
