Description

pouch

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 pouches of the prior art are 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 isolation portion or an insulating sheet separating them.

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

The conventional exothermic unit has a plurality of accommodating portions formed in a lattice shape in which a pair of permeable sheets are faced to each other and the exothermic reactants are accommodated therebetween. The injected water penetrates into the exothermic reactant accommodating part through both sides of the exothermic unit.

However, heat is transferred to the contents through only one side by the heating unit, and heat on the other side is dissipated to the outside and is lost. This reduces the thermal efficiency, in some cases may be delivered to the user's hand and may be inconvenient for the user.

Accordingly, an object of the present invention is to provide a pouch having improved thermal efficiency and usable by a user.

Here, the heating unit is preferably separated into a plurality between the water-permeable sheet and the water-permeable sheet.

The pouch body may further include a reaction liquid injecting unit for injecting a reaction liquid into the exothermic unit accommodation space and a content input unit for injecting contents into the contents accommodation space.

In addition, the exothermic reactant is composed of one or more of calcium oxide (CaO), calcium hydroxide (Ca (OH) ₂ ), magnesium chloride (MgCl ₂ ), iron (Fe), and aluminum (Al), and is impermeable to water. The sheet is made of at least one material of PE (polyethylene), PP (polypropylene) and PET (polyethylene terephthalate).

In addition, the impermeable sheet of the heat generating unit is attached to form a gap with the pouch body, or the impermeable sheet is to include embossing in the direction to be attached to the pouch body.

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 isolation unit 150 existing in the pouch body 120, and the isolation unit It consists of a heating unit 200 existing between the 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 isolation unit 150 is adhered to the pouch body 120 to be received and supported.

As shown in FIG. 2, the pouch body 120 is divided into a content accommodation space 130 and a heating unit accommodation space 140 by the isolation unit 150. The isolation part 150 forming the encapsulated content accommodating space 130 is adhered to the inner wall surface of the pouch body 120 near the top opening 180 of the pouch body 120. In addition, the isolation unit 150 is partitioned so that the bottom region is bonded to the inner wall surface of the pouch body 120 in the bottom region of the pouch body 120 so that the contents accommodation space 130 and the heating unit accommodation space 140 are arranged side by side. It is possible.

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

The pouch body 120 forms a reaction liquid injection unit 160 to enable water injection into the heat generating unit accommodation space 140. When water enters the exothermic unit accommodation space 140 by the reaction liquid injecting unit 160, the water comes 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 may be provided with a water pouch which can be opened by an external force together with the heat generating unit 200 in the heat generating unit accommodation space 140 without being separately present.

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.

Water introduced into the heat generating unit accommodation space 140 through the reaction liquid injecting unit 160 is absorbed in the direction of the water permeable sheet 220 when it is in contact with the heat generating unit 200, and is blocked in the direction of the water impermeable sheet 210. . Water absorbed into the water-permeable sheet 220 generates heat when it comes into contact with the heat-generating reactant 240 present in the heat-generating reactant accommodating part 230, and the temperature of the heat felt toward the water-permeable sheet 220 is High but impermeable to the heat impermeable sheet 210 direction is lower than the water permeable sheet 220 is felt. Since the heat is concentrated in the direction of the permeable sheet 220, the permeable sheet 220 may feel a higher temperature than when the heat is not concentrated. When the water-permeable sheet 220 is directed toward the isolation unit 150, the isolation unit 150 transmits a higher temperature than when the water-impermeable sheet 210 is directed. The water-impermeable sheet 210 on the opposite side of the water-permeable sheet 220 transmits a lower temperature than the water-permeable sheet 220 and exists in the direction of the pouch body 120 so that it is easy for a user to hold by hand. 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 to facilitate heat transfer to the contents.

When the exothermic reactant accommodating part 230 is composed of a single dog, the space of the exothermic reactant accommodating part 230 is large, so that the flow of the exothermic reactant 240 increases. In this case, the isolation unit 150 does not generate heat as a whole, and heats only the portion where the exothermic reactant 240 is collected, which is difficult to heat the contents. In order to compensate for this, the heating unit 200 has a plurality of lattice adhesive parts in which the exothermic reactant accommodating portion 230 is divided into a lattice shape, and the exothermic unit 200 is entirely heated by the plurality of exothermic reactant accommodating portions 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, the water-permeable sheet 210 and the water-permeable sheet 220 may be bonded not only by thermal fusion but also by ultrasonic fusion or an adhesive. In addition, the water-impermeable sheet 210 may be made of a material that is impermeable, 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 made of a liquid or a solid. However, in order to prevent the exothermic reactant 240 from being released to the outside of the water-permeable permeable sheet 220, a solid material 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.

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

The heating unit 200 adhered to the pouch body 320 attaches the water-permeable sheet 210 to the pouch body 320 only at both ends, thereby creating a gap between the pouch body 320 and the heating unit 200. As described above, the heating unit 200 does not fix the entire water-impermeable sheet 210 to the pouch body 320 so that the gap is generated between the heating unit 200 and the pouch body 320 and the user of the pouch body 420 is used. When holding by the hand, the heat generating unit 200 is not in direct contact with the user's hand, the heat transfer from the heat generating unit 200 is minimized.

The reaction liquid injection unit 360 and the contents injection unit 370 are basically the same, but there is a difference in that the impermeable sheet 250 of the exothermic unit 200 is embossed.

The embossing of the water-impermeable sheet 250 is a plurality of protruding toward the pouch body 320, the gap is formed by the embossed protruding when the heating unit 200 is bonded to the pouch body 320. In the embossing, as in the gap in the third embodiment, the heat generating unit 200 does not directly contact the user's hand, and thus heat transfer is reduced to the user's hand.
