Description

Heat pack with improved heating efficiency and contents heating kit including same {FLAMELESS HEATING PACK WITH HIGH HEAT EFFICIENCY AND PACKAGE FOR HEATING CONTENT INCLUDING THE SAME}

The present invention relates to a heating pack and a contents heating kit including the same, and more particularly, to a heating pack and a contents heating kit including the same to improve heating efficiency.

The heating pack is a pack capable of heating the contents without a separate heating device by the exothermic reaction of the liquid reaction liquid and the solid state heating element, and is widely used for heating foods and the like because it is easily portable.

In this exothermic process, the reaction liquid is vaporized to generate a reactive gas (steam or steam), and the generated reactive gas is simply discharged through a steam outlet formed at an outer edge of the heat generating pack.

Since the reactor body also has considerable thermal energy, it is not desirable to discharge it simply in terms of energy efficiency.

Accordingly, it is an object of the present invention to provide a heating pack and a contents heating kit including the same, which improves heating efficiency by recycling a reactive gas.

In addition, another object of the present invention, in addition to the contents accommodated in the heat pack itself is to provide a heat pack that can also heat the contents arranged around the heat pack and the content heating kit comprising the same.

According to the present invention, in the heat pack, a pouch having an accommodation space and an opening in communication with the accommodation space; A partition part disposed in the pouch and partitioning the accommodation space into an exothermic space in which an exothermic reaction occurs in a contents accommodating space, and allowing a reactive gas generated by the exothermic reaction to enter the contents accommodating space; It can be achieved by a heat generating pack characterized in that it comprises a heat generating portion accommodated in the heat generating space causing the exothermic reaction.

Here, the partition unit, the reactor body inlet opening is provided so that the reactor body is introduced into the contents receiving space; The reactor body may include a through-flow member disposed in the inlet opening to allow the reactor to be introduced into the contents receiving space and to suppress the reaction liquid from the exothermic reaction into the contents receiving space.

The partition unit may further include a first compartment member and a second compartment member for partitioning the heat generating space into a first heat generating space and a second heat generating space, respectively, with the content receiving space therebetween.

The heating unit may include at least any one of a reaction liquid and a heating element that cause an exothermic reaction when contacted with each other.

The heating unit may include only one of the heating element and the reaction liquid, and the pouch may further include an input unit for introducing the other of the reaction liquid and the heating element into the heating space.

Here, the opening may be formed at the lower end of the pouch, and the reactor body passage member may be disposed between the opening and the inlet. Accordingly, the reactor body may pass through the reactor body passage member and then be discharged to the outside of the heat generating pack through the opening.

In addition, the pouch may further include an opening and closing portion that can open and close the input portion.

The object is, according to the present invention, in the contents heating kit, the above-mentioned heat pack; The reactor pack accommodates the heat generating pack, and also accommodates other contents arranged around the heat generating pack with respect to the heat generating pack, wherein the reactor body discharged from the heat generating pack is discharged after passing the other contents. It can also be achieved by a contents heating kit comprising an outer pack having an outlet.

According to the heating pack and the contents heating kit including the same configured as described above has the following effects.

First, heating efficiency can be improved because the reactor generated during the exothermic reaction is used for heating the contents again without being discharged to the outside. Accordingly, the time required for heating the contents can be advanced.

Second, the other contents disposed around the heat generating pack may be heated together using the reactor gas discharged from the heat generating pack, and the plurality of contents may be heated at once. This further improves the convenience of use.

Hereinafter, the heating pack and the contents heating kit including the same according to a preferred embodiment of the present invention with reference to the accompanying drawings will be described in detail.

The contents heating kit 1 according to the first embodiment of the present invention, as shown in Figure 1 and 2, the outer pack 10 to form an appearance; It includes a heat pack 100 accommodated inside the outer pack (10).

As illustrated in FIG. 2, at least one other content A and B disposed around the heat pack 100 may be accommodated in the outer pack 10.

Here, the other contents A and B are for distinguishing from the contents (see C of FIG. 5) accommodated in the heat pack 100. Examples of the other contents A and B include side dishes, condiments or sauces. And, as an example of the contents contained in the heat pack 100 may be cooked food, such as rice.

The outer pack 10 is composed of a first outer shell 11 and a second outer shell 12. Of course, the outer pack 10 may be integrally composed of only one outer shell.

It is sufficient that the outer pack 10 can accommodate the heat pack 100 therein.

An opening 13 may be formed at an upper side of the outer pack 10 to allow the heat pack 100 to be inserted therein. The reactor body of the heat generating pack 100 may be discharged through the opening 13, which will be described later.

Here, the outer pack 10 may be made of a synthetic resin such as PE (polyethylene), PP (polypropylene) and PET. The outer pack 10 is preferably not torn even in the external impact. In addition, the outer pack 10 is preferably provided to have an inner space corresponding to the volume of the other contents (A, B) and the heat generating pack 100 to be accommodated therein. This is to increase the portability by minimizing the volume of the outer pack (10).

3 to 5, the heat pack 100, a pouch 110 having an accommodation space (S) and the opening 115 in communication with the receiving space therein; A partition part 120 disposed in the pouch 110 and partitioning the accommodation space S into heat generating spaces S2 and S3 in which exothermic reactions occur with the contents accommodating space S1; And a heat generating unit 130 accommodated in the heat generating spaces S2 and S3 to cause the heat generating reaction.

Here, in the first embodiment, it will be described as an example that the heat generating space is divided into two plurality of heat generating spaces (S2, S3).

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

The contents C, which are input or taken out through the opening 115, are accommodated in the contents accommodation space S1.

On the other hand, the partition unit 120 is the first compartment member 121 and the second compartment member 123 for partitioning the heat generating space (S2, S3) into a first heat generating space (S2) and a second heat generating space (S3). ).

The compartment 120 is a reactor (steam or steam) generated by the exothermic reaction in the heat generating space (S2, S3) is introduced into the contents receiving space (S1) in the heat generating space (S2, S3). To allow.

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

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

Here, experiments were carried out on the permeability of the reactor gas and the impermeability of the reaction liquid by the exothermic reaction using the nonwoven fabric made of polypropylene. According to the test result, it is preferable that the basis weight (g / m 2) of the polypropylene nonwoven fabric 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 the reaction liquid water permeated 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 S1.

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 body 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 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 at the reactor inlet opening 122.

In some cases, the reactor passage member 125 may be omitted. For example, when exothermic reactions occur in the exothermic spaces S2 and S3, the reaction liquid is located below the exothermic spaces S2 and S3 because of its own weight. Therefore, if the heat generating pack 100 can be maintained in an upright state as shown in FIG. 5, the reaction liquid is unlikely 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 maintain the heat pack 100 in the standing state. In some cases, when the outer pack 10 is provided with a heat insulating material, the user may hold the outer pack 10 by hand without the holder and maintain the heat pack 100 therein in a standing state. .

On the other hand, the reactor body passage member 125 allows the reactor body by the exothermic reaction in the exothermic space (S2, S3) to be introduced into the contents receiving space, but the reaction liquid by the exothermic reaction is to accommodate the contents Ingress into space acts as a deterrent. Here, the term 'inhibit' does not mean 100% of the reaction liquid is introduced, but rather means that the reaction liquid may be introduced into the contents receiving space.

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 that transmits 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 unit 113, which will be described later, the reactor fluid passage member 125 easily guides the introduced reaction liquid or the heating element to the exothermic space (S2, S3). It can be arranged in an inclined "??" shape.

In more detail, as illustrated in FIG. 5, both sides of the reactive gas passage member 125 are inclined to the first heat generating space S2 and the second heat generating space S3, respectively. It may be provided to have a "??" 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 S2 and the second heat generating space S3.

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 above examples as long as it can exothermicly react with the reaction liquid.

1 to 5 illustrate that the heating unit 130 has only a heating element as an example. In some cases, the heating unit 130 may include only a reaction liquid (for example, 'water') instead of the heating element.

As described above, when the heat generating unit 130 includes only one of the heating element or the reaction liquid, the user generates heat by injecting the other one through the input unit 113 formed in the pouch 110. It can cause a reaction.

According to the example shown in FIGS. 1 to 5, the user may cause an exothermic reaction by adding water, which is a reaction liquid, through the input unit 113.

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

In addition, as another example, the heat generating unit 130 may include both the heating element and the reaction liquid receiver containing the reaction liquid 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 or tearing or tearing the reaction liquid container. In this case, the input unit 113 may be omitted since the heating element or the reaction liquid does not need to be introduced through the input unit 113 to cause an exothermic reaction.

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

The opening and closing part 114 may be provided in the form of a zipper lock, as shown in FIG. The opening and closing method shown in FIG. 5 is merely an example, and a so-called squeezer type or adhesive type, and various other known opening and closing methods may be employed.

Here, when the opening and closing part 114 closes the input part 113, it is preferable that the sealing member is highly sealed so that the reactor body does not leak through the input part 113.

6 and 7, when the reaction liquid is introduced into the exothermic spaces S2 and S3 through the input unit 113, the injected reaction liquid is the first and second heat generation. Communication holes 121a and 123a may be provided at lower side edges of the partition members 121 and 123 so as to be able to flow between the spaces S2 and S3.

In some cases, the reaction liquid introduced through the input unit 113 may be concentrated in only one of the plurality of heat generating spaces (S2, S3), even if the reaction liquid is the communication port. It may flow to the other heat generating space through (121a, 123a).

On the other hand, Figure 6 is an exploded perspective view of the heat pack 100 according to the first embodiment described above.

The first outer shell 111 and the first partition member 121 of the pouch 110, except for the portion to be the reactor inlet opening 122 while receiving the heat generating portion 130 therein. It is sealed along the edge of the first partition member 121.

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

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

The space between the first compartment member 121 and the second compartment member 122 becomes the content accommodation space S1. The first compartment member 121 and the second compartment member 122 may include the opening 115 for introducing the contents C into the contents accommodation space S1, and the heat generating space of the reactor body. Sealing each other to form the reactor inlet opening (122) for the inlet to the contents receiving space (S1) in (S2, S3). As shown in FIG. 6, the width of the opening 115 is an unsealed lower section w of the first compartment member 121 and the second compartment member 122.

FIG. 8 shows the flow of the reactor body as an arrow when heating the contents C and the other contents A and B of the contents heating kit 1 of the first embodiment described above.

When the exothermic reaction occurs, the reactive gas is generated in the first and second heat generating spaces S2 and S3.

The generated reactant is the opening and closing part 114 is sealed to the input part 113, it is not discharged through the input part 113, and passes through the reactor body passage member 125 to the contents receiving space (S1) Inflow).

The introduced reactor body heats the contents (C). Of course, the contents C are heated by conducting heat generated in the first and second heat generating spaces S2 and S3 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 (S1) is wide in the contents (C) is shown that the contents (C1) and each of the first compartment member 121 and the second compartment 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 S1 and S2 to easily heat the contents C by heat conduction, the contact area between the contents C, the first compartment member 121 and the second compartment member 123 is maintained. It is preferable to make this wide.

The reactor body passing through the contents (C) heats the other contents (A, B) while passing through the other contents (A, B) disposed around the heat generating pack (100).

Thereafter, the reactor body is discharged to the outside through the opening 13 formed in the outer pack (1).

Here, it is preferable that the outer shell 1 has a heat insulating material so that the first outer shell 11 and the second outer shell 12 of the outer pack 1 are heat insulating materials. In some cases, a coating layer having heat insulation may be formed on the inner surface or the outer surface of the first outer shell 11 and the second outer shell 12.

In the first embodiment described above, the heat generating pack in which the plurality of heat generating spaces S2 and S3 are formed with the content receiving space S1 therebetween has been described. It can also be changed to a heat pack having a structure forming a receiving space.
