The present invention relates to a pouch.

There's a pouch in a disposable package to warm food easily, without tools, outdoors or for military training. The pouch of the prior art is generally composed of a content accommodating space accommodating the contents, a heat generating unit accommodating space accommodating the heat generating unit for heating the contents, and an inner accommodating portion or insulating sheet separating the compartments.

The exothermic unit has one or more accommodating parts in which exothermic reactants are accommodated. When water is injected from the outside, water penetrates into the receiving unit of the exothermic unit, and the exothermic reactant generates heat by a hygroscopic exothermic reaction. To this end, the heating unit is manufactured using a water-permeable sheet to allow water absorption.

In the prior art, a water inlet for injecting water to be supplied to the exothermic reactant and a content inlet for injecting the contents are provided separately. If the contents should not come in contact with water, the water receptacle and the contents receiving space should be separated, but the contents do not need to be isolated from the water, i.e. the contents are packaged by a sealing material or the contents themselves are In the case of not penetrating, a plurality of injection or inlet ports can complicate the structure and increase the manufacturing cost.

It is therefore an object of the present invention to provide a pouch with a simple structure and which can reduce manufacturing costs.

According to an embodiment of the present invention, the above object is a pouch, comprising: a pouch body having an opening; An inner accommodating part which forms a contents accommodating space accommodating and supported in the pouch body and accommodates the packaged contents and allows the liquid introduced from the input opening to pass therethrough; It is achieved by a pouch provided between the pouch body and the inner accommodating portion and having at least one exothermic unit including an exothermic reactant reacting with the liquid passing through the inner accommodating portion.

Here, the inner accommodating part is to include at least one reaction liquid through hole.

In addition, the inner accommodating part is made of a water-permeable material, and the water-permeable material is preferably made of any one of a water-permeable paper, a nonwoven fabric, and a mesh.

In addition, the packaged content is to include a withdrawal member to be able to withdraw to the outside in the contents receiving portion.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

Pouch 100 according to the first embodiment of the present invention, as shown in Figs. 1 and 2, the pouch body 120, the inner accommodating portion 150 existing inside the pouch body 120, and the inside It consists of a heating unit 200 existing between the receiving unit 150 and the pouch body 120.

The pouch body 120 is sealed using an adhesive, heat fusion or ultrasonic welding except for one side edge. The pouch body 120 is accommodated and supported by the inner accommodating part 150 at the one side edge. When the uppermost part of the pouch body 120 and the uppermost part of the inner accommodating part 150 are adhered to each other, the opening opening 180 when sealing the pouch 100 has four layers. However, when the top of the pouch body 120 is higher than the top of the inner accommodating part 150 or protrudes out of the pouch body 120, the input opening 180 is formed in two layers. do. The input opening 180 is convenient for the user to open the pouch body 120 by cutting the pouch 100 when the two ply than four ply.

The pouch body 120 may be made of a material that is impervious to PE (polyethylene), PP (polypropylene), or PET (polyethylene terephthalate), and is not easily torn from external impact. Of course, in addition, it may be made of a synthetic resin film of a variety of known materials.

The inner accommodating part 150 has the contents input part 170 thereon, and forms the contents accommodating space 130 in a sealed shape. As shown in FIG. 2, the inner accommodating part 150 injects water into the contents accommodating space 130 from the input opening 180 to allow the water to enter the heat generating unit accommodating space 140. 160). When water is injected into the content accommodation space 130, the water passing through the reaction liquid through hole 160 is absorbed into the heat generating unit accommodation space 140 when it is injected into the heat generating unit accommodation space 140, and the absorbed water exothermic reaction. It meets the sieve 210 and generates heat to heat the contents 900. The contents 900 accommodated in the contents accommodating space 130 directly injects water into the contents accommodating space 130 through the input opening 180, so that the rice or herb pack is sealed without problems in contact with water. Etc. are appropriate. In addition, the pouch 100 may be manufactured and sold so that the contents 900 are accommodated in the contents accommodation space 130 in advance. In some cases, the reaction liquid passage hole 160 may have one or more, and the position, size and shape of the reaction liquid passage hole 160 may be changed.

When using the inner accommodating part 150 having the reaction liquid passage hole 160 as described above, the pouch body 120 does not have to separately make a water inlet connected to the heating unit accommodating space 140. When the water inlet is not formed, there is a case in which the water pouch is separately provided in the prior art. Since the pouch 100 including the inner accommodating part 150 is not provided with the water pouch, the manufacturing cost is increased. Savings.

The exothermic unit 200 accommodated in the exothermic unit accommodating space 140 includes the exothermic reactant 210. The heat generating unit 200 is made of a nonwoven fabric, water-permeable paper or mesh so that water can be permeated. In some cases, the heat generating unit 200 may have the same material as the inner accommodating part 150. In addition, the number of heat generating units 200 accommodated in the heat generating unit accommodation space 140 may be one or more. As the number of heat generating units 200 increases, the contents 900 may be heated in a short time.

The exothermic reactant 210 accommodated in the exothermic unit 200 may be formed of a liquid or a solid. However, in order to prevent the exothermic reactant 210 from being released to the outside of the heat generating unit 200 having water permeability, a solid material is used as a more preferable material. Exothermic reactant 210 made of a solid may be composed of one or more of calcium oxide (CaO), calcium hydroxide (Ca (OH) ₂ ), magnesium chloride (MgCl ₂ ), iron (Fe) and aluminum (Al). have.

The second embodiment according to FIG. 3 is basically the same as the first embodiment of FIG. 2, the pouch 300, the pouch body 320, the contents accommodating space 330, the heat generating unit accommodating space 340, Although the contents input part 370, the input opening 380, the heat generating unit 200, and the heat generating reactant 210 are included, there are differences in the shape of the internal accommodating part 350.

The inner accommodating part 350 may use the inner accommodating part 350 itself having a water permeability so as to be permeable without the reaction liquid passing hole 160. The preferred material of the inner accommodating portion 350 having water permeability may be water permeable paper or nonwoven fabric. The water-permeable paper is a material such as a tea bag that is generally used, a material that is permeable but not easily torn is used. In addition, the inner accommodating part 350 may be used as the inner accommodating part 350 as well as the water-permeable species, the nonwoven fabric capable of water permeation.

In this case, when water is injected into the contents accommodating space 330, water is absorbed into the inner accommodating part 350 and water is injected into the heat generating unit accommodating space 340, thereby exothermic reaction present in the heat generating unit 200. Sieve 210 is in contact with water to generate heat.

The third embodiment according to FIG. 4 is basically the same as the first embodiment of FIG. 2, the pouch 400, the pouch body 420, the contents accommodation space 430, the heating unit accommodation space 440, Although the contents input part 470, the input opening 480, the heat generating unit 200, and the heat generating reactant 210 are provided, there are differences in the shape of the internal accommodating part 450.

The inner accommodating part 450 is formed of a mesh so that water introduced into the inner accommodating part 450 can pass directly into the heat generating unit accommodating space 440. The mesh-shaped inner accommodating part 450 is recently used in triangle tea bags, and is made of PE (polyethylene) or PET (polyethylene terephthalate) which is harmless to human body and does not deform even at high temperature. Such an inner accommodating part 450 is not easily damaged even when the sharp content 900 is injected, and thus is preferable as the inner accommodating part 450.

If the pouch 400 of the third embodiment does not have a condition for discarding water after the heating is completed, the water must be stored in the pouch body 420 as it is. The injected water does not escape well into the contents accommodating space 330 again, but the inner accommodating part 450 having a mesh shape should be completely sealed because water is easily taken out. Therefore, the zipper 490 may be further included in the input opening 480 to seal the water present in the pouch body 420 without being discarded.

The input opening 480 may exist in the pouch body 420, but when the inner receiving portion 450 protrudes outward from the pouch body 420, the input opening 480 is present in the inner receiving portion 450. The zipper 490 is formed in the input opening 480. The zipper 490 is a male zipper 492 which is grooved, and a male zipper 494 corresponding to the groove of the female zipper 492 and engaged with the female zipper 492 to seal the pouch 400. consist of. This zipper 490 is generally the same as the zipper present in a zipper bag for storing food and the like at home. However, in some cases, the shape of the zipper 490 may be changed.

The fourth embodiment according to FIG. 5 is basically the same as the first embodiment of FIG. 2, the pouch 500, the pouch body 520, the contents accommodation space 530, the heating unit accommodation space 540, Although it has an internal accommodating part 550, a content input part 570, an input opening 580, a heat generating unit 200, and a heat generating reactant 210, the difference is that it further includes a drawing member 590. have.

The contents 900 heated in the contents accommodating space 530 may be inconvenient to take out the contents 900 due to the high temperature of the heated water. In order to solve this problem, the contents 900 further include a withdrawal member 590 to use a string or string to which the forceps are connected, or to easily extract the contents 900 by tying the string or string to the contents 900. The contents 900 are present in the contents accommodating space 530 by using the form of hanging the withdrawal member 590 to the contents 900 or tying the withdrawal member 590 to the contents 900. The heated content 900 can be withdrawn from the input opening 580 using the withdrawal member 590. The drawing member 590 may be, for example, a wire, a tape, a strip, a string, or the like, but is not limited thereto.

Since the

pouches

100, 300, 400, and 500 do not have to have a separate water inlet for injecting water, the

pouches

100, 300, 400, and 500 have a simple structure, thereby reducing manufacturing costs. In addition, since the user injects water toward the

openings

180, 380, 480, and 580 of the

pouches

100, 300, 400, and 500, it is easier to inject water than when there is a separate water injection hole.
