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 a method such as using an adhesive, heat welding or ultrasonic welding except for one side edge. The pouch body 120 may be formed of a material that is impermeable to the material such as PE (polyethylene), PP (polypropylene) or PET (polyethylene terephthalate) and is not easily torn from external impact. Inside the pouch body 120, the inner accommodating part 150 is adhered to the pouch body 120 to be received and supported.

As shown in FIG. 2, the pouch body 120 is separated and partitioned into the contents accommodation space 130 and the heating unit accommodation space 140 by the internal accommodation portion 150. The inner accommodating part 150 forming the encapsulating contents accommodating space 130 has an upper region bonded to the inner wall surface of the pouch body 120 near the input opening 180 of the pouch body 120, and a lower region is provided. The bottom wall of the pouch body 120 is bonded to the inner wall surface of the pouch body 120 can be partitioned so that the contents accommodating space 130 and the heating unit accommodating space 140 are arranged side by side.

The inner accommodating part 150 may be formed of a sheet having water permeability or forming a through-hole to inject water into the contents accommodating space 130 to enter the water into the heat generating unit accommodating space 140. In this case, since the contents accommodated in the contents accommodating space 130 should not have any problem in contact with the water, the contents can be applied to a case such as a sealing pack containing rice or Chinese medicine. In addition, the contents accommodating space 130 is accommodated in advance, the contents can be produced, sold.

In the pouch body 120, a reaction liquid injection unit 160 is formed to enable the water injection into the heat generating unit accommodation space 140. When the water enters the exothermic unit accommodation space 140 by the reaction liquid injecting unit 160, the water is brought into contact with the exothermic unit 200 accommodated in the exothermic unit accommodation space 140. As a result, the heating unit 200 generates heat to heat the contents. Although the reaction liquid injection unit 160 is formed on the upper portion of the pouch body 120, the number and position of the reaction liquid injection unit 160 may be changed in some cases. In addition, the reaction liquid injection unit 160 does not exist separately, it is also possible to include a water pouch with the heat generating unit 200 in the heat generating unit accommodation space 140.

The heat generating unit 200 accommodated in the heat generating unit accommodation space 140 includes a water-permeable sheet 220, an impermeable sheet 210 bonded to the water-permeable sheet 220, a water-permeable sheet 220, and an impermeable sheet. The exothermic reactant accommodating part 230 formed between the sheets 210 and the absorption exothermic exothermic reactant 240 accommodated in the exothermic reactant accommodating part 230 are included. In some cases, one or more heat generating units 200 may exist.

When the water introduced into the heat generating unit accommodation space 140 through the reaction liquid injecting unit 160 comes into contact with the heat generating unit 200, the water is absorbed in the direction of the water permeable sheet 220, and the water impermeable sheet 210. The water is blocked in the direction. When the water absorbed into the water-permeable sheet 220 contacts the exothermic reactant 240 present in the exothermic reactant accommodating portion 230, the water generates heat. Although high, the heat generation in the direction of the impermeable sheet 210 is blocked to feel a lower temperature than the water-permeable sheet 220. The heat generation is concentrated in the direction of the water-permeable sheet 220, when the water-permeable sheet 220 that can feel a higher temperature than when not concentrated toward the inner receiving portion 150, the inner receiving portion 150 is impermeable sheet When the 210 can feel a higher temperature, and the water impermeable sheet 210 present in the opposite side of the water-permeable sheet 220 is present in the pouch body 120 direction when the user grasps the water-permeable sheet You feel a relatively lower temperature than 220, even if you hold it by hand does not feel uncomfortable. In some cases, the water impermeable sheet 210 may be bonded to the pouch body 120 to fix the heat generating unit 200 so as not to move in the heat generating unit accommodation space 140 so that heat may be easily transferred to the contents.

When the exothermic reactant accommodating part 230 is a single dog, the space of the exothermic reactant accommodating part 230 is large and the flow of the exothermic reactant 240 is increased. In this case, there is a difficulty in heating the contents by strongly heating only the portion where the exothermic reactant 240 is collected without heat generation as a whole. In order to compensate for this, the exothermic reactant accommodating part 230 has a plurality of lattice adhesive parts partitioned into a lattice shape in the exothermic unit 200, and the exothermic unit 200 generates heat by the plurality of exothermic reactant accommodating parts 230. Be sure to The lattice adhesive part refers to a portion where the water-permeable sheet 210 and the water-permeable sheet 220 are bonded to each other, and the water-impermeable sheet 210 and the water-permeable sheet 220 are fused using mutual heat fusion. For heat fusion, the impervious sheet 210 and the permeable sheet 220 are preferably of the same material, and at least the main components of the same are not necessarily the same material. In some cases, not only thermal fusion but also ultrasonic fusion or adhesive using an adhesive is possible. In some cases, the water-impermeable sheet 210 may be made of a material that is impermeable to the material such as PE (polyethylene), PP (polypropylene) or PET (polyethylene terephthalate) and is not sensitive to temperature.

The water-permeable sheet 220 may be made of various materials and shapes. The water-permeable sheet 220 should be made of a material and a form capable of absorbing water, and preferred materials and forms include a nonwoven fabric, a water-permeable paper, and a mesh. First, the nonwoven fabric is not only capable of absorbing water but also is not easily torn or damaged, and thus is preferable as the water-permeable sheet 220. In addition, the water-permeable paper may be a paper generally used in tea bags, which is also excellent because of its excellent water permeability. In addition, the mesh made of PE (polyethylene) or PET (polyethylene terephthalate) is used in a tea bag like the water-permeable paper, which is also excellent in water permeability, and less permeable to impact than the water-permeable paper, and thus permeable. It is preferred for the sheet 220.

The exothermic reactant 240 that generates heat when contacted with water is accommodated in the exothermic reactant accommodating portion 230. The exothermic reactant 240 may be formed of a liquid or a solid. However, in order to prevent the exothermic reactant 240 from being released to the outside of the permeable sheet 220 having a permeability, a solid is used as a more preferable material. The exothermic reactant 240 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.

3, the pouch 300, the pouch body 320, the contents accommodating space 330, the exothermic unit accommodating space 340, and the reaction liquid injecting part 360 as in the first embodiment of FIG. 2. ), The contents input part 370, the input opening 380 and the heating unit 200 are basically the same, but there is a difference in the shape of the inner receiving portion 350 bonded to the pouch body 320. .

The inner accommodating part 350 has a contents input part 370 thereon, and the upper part of the inner accommodating part 350 is bonded to the pouch body 320 to form a contents accommodating space 330 in an encapsulated shape. The inner accommodating part 350 is adhered or fused to the inner wall surface of the pouch body 320 along the region of the contents input part 370 by using an adhesive, thermal fusion, or ultrasonic fusion.

The reaction liquid injection unit 460, the content injection unit 470, and the heat generation unit 200 are basically the same, but there is a difference in the shape in which the heat generation unit 200 is bonded to the pouch body 320.

The water-permeable sheet 210 of the heat generating unit 200 is attached to the pouch body 320 only at both ends to make a gap between the pouch body 320 and the heat generating unit 200. As such, if the entire water-impermeable sheet 210 is not fixed to the pouch body 320, the gap is generated, and when the user holds the pouch body 420 by hand, the gap exists in the pouch body 420 by the gap. The heating unit 200 is separated from the user's hand. As a result, the user may feel the heat generated in the heat generating unit 200 to a minimum, thereby reducing the inconvenience of the user.

In the fourth embodiment according to FIG. 5, the pouch 300, the pouch body 320, the contents accommodation space 330, the heating unit accommodation space 340, and the interior accommodation part 350 are similar to the second embodiment of FIG. 3. The reaction liquid injection unit 360 and the content injection unit 370 are basically the same, but there is a difference in that the impermeable sheet 250 of the heat generating unit 200 is embossed.

The embossing of the water impermeable sheet 250 is a plurality of protrusions in the direction of the pouch body 320, when the heat generating unit 200 is bonded to the pouch body 320, the gap is present by the embossed protrusion. As for the embossing, the user's hand and the heating unit 200 are spaced apart from each other in the same manner as the gap in the third embodiment, so that the user can feel the heat generated in the heating unit 200 to a minimum. It is included to reduce.
