  • the vertical pouch 100 includes a first pack 101 , a second pack 102 , and a content container 160 formed between the first pack 101 and the second pack 102 .
  • a first sheet 110 and a second sheet 120 are adhered to each other only at its ending part so as to form a space in the middle of the first sheet 100 and the second sheet 120 .
  • a heating element 10 is accommodated in the middle space formed by adhering the first sheet 110 and the second sheet 120 .
  • the heating element 10 may include a liquid or solid material that reacts with a reaction liquid and causes an exothermic reaction.
  • the sold material may be used to prevent the heating element 10 from leaking out.
  • the solid heating element 10 may include one or more among calcium oxide (CaO), calcium hydroxide (Ca(OH) 2 ), magnesium chloride (MgCl 2 ), iron (Fe) and aluminum (Al).
  • the adhering process may be achieved by a method of piling up the first sheet 110 , the heating element 10 and the second sheet 120 in sequence and adhering four edges thereof, or a method of first adhering the edges of the first sheet 110 and the second sheet 120 in the form of ‘U’ except the upper edge and then sealing up the upper edge after inserting the heating element 10 through the upper edge.
  • the second pack 102 may be formed by adhering edges of a third sheet 130 and a fourth sheet 140 , and accommodates the heating element 10 in a space formed by adhering the third sheet 130 and the fourth sheet 140 like the first pack 101 .
  • Such adhesion between the sheets 110 , 120 , 130 and 140 may be achieved by heat sealing, high frequency sealing or the like.
  • the first sheet 110 forming an outer surface of the pouch 100 includes a plurality of sheet members 112 , 114 and 116 .
  • the fourth sheet 140 also includes a plurality of sheet members 142 , 144 and 146 .
  • the first sheet 110 and the fourth sheet 140 When heat is generated inside the pouch 100 , heat is transferred to a user's body being in contact with the pouch 100 or to the outside.
  • the first sheet 110 and the fourth sheet 140 include a plurality of layers. As the first sheet 110 and the fourth sheet 140 are formed by the plurality of layers, it is also possible to protect the heating element 10 or the content from external shock. If a reaction liquid bag is enveloped together with the heating element 10 , the plurality of layers may prevent the reaction liquid bag from being damaged by external shock and wastefully react with the heating element 10 .
  • Sheet members 112 and 142 provided in the outmost surface of the first sheet 110 and the fourth sheet 140 are comprised of by insulating sheet members so as to further minimize heat transfer to a user.
  • the insulating sheet member may be applied to not only the outmost sheet members 112 and 142 but also the other sheet members 114 , 116 , 144 and 146 , and a plurality of insulating sheet members may be used for the first sheet 110 and the fourth sheet 140 .
  • the insulating sheet member may include polyurethane, polystyrene, calcium silicate or the like.
  • the second sheet 120 of the first pack 101 and the third sheet 130 of the second pack 102 may include a plurality of sheet members.
  • the second sheet 120 may include two sheet members 122 and 124 and an air-gap 126 formed between the plurality of sheet members 122 and 124 .
  • the third sheet 130 may include two sheet members 132 and 134 and an air-gap 136 between the sheet members 132 and 134 .
  • the heating element 10 reaction gas generated by reaction between the reaction liquid and the heating element 10 , or the like may flow in the content container 160 when a minute pinhole is generated in the second sheet 120 and the third sheet 130 .
  • the second sheet 120 and the third sheet 130 are configured to the plurality of sheet members 122 , 124 , 132 and 134 , respectively.
  • the air-gaps 126 and 136 serve to protect the content accommodated in the content container 160 from being damaged or deformed by external shock.
  • the air-gap 126 is formed by adhering edges of the sheet members 122 and 124 to form a space in the middle. This manner is also applied to the air-gap 136 of the third sheet 130 .
  • the second sheet 120 and the third sheet 130 are adhered to each other at opposite longitudinal end portions.
  • the bottom 150 is adhered to the lower portions of the second sheet 120 and the third sheet 130 .
  • the bottom 150 includes a fold 152 to be folded upward or downward in the pouch 100 .
  • the bottom 150 is folded usually, and is pulled and stretched out in directions of the first sheet 110 and the fourth sheet 140 and laid down so that the pouch 100 can be stood.
  • the pouch 100 is decreased in volume to be easily kept.
  • the bottom 150 is stretched out, the pouch 100 can be stood to be convenient for a user to eat the content in the pouch 100 . Further, if the pouch 100 is stood during the exothermic reaction of the heating element 10 , a user is free from getting burned since the user does not have to hold the pouch 100 with the user's hand.
  • the content container 160 formed by the second sheet 120 , the third sheet 130 and the bottom 150 is provided inside the pouch 100 .
  • the content container 160 may be filled with the content such as food, and the content such as food is heated by the heating element 10 . If food is directly filled in the content container 160 , the second sheet 120 , the third sheet 130 and the bottom 150 may be made of materials harmless to humans.
  • the first pack 101 and the second pack 102 include a reaction liquid passage 170 through which they communicate with each other.
  • the reaction liquid passage 170 is formed to make the first pack 101 and the second pack 102 communicate with each other so that the reaction liquid introduced into the first pack 101 can flow to the second pack 102 .
  • the reaction liquid introduced into the second pack 102 may flow to the first pack 101 .
  • the reaction liquid passage 170 is formed by penetrating an adhered portion where the second sheet 120 and the third sheet 130 are partially adhered. The adhered portion has to be penetrated so that the reaction liquid can flow only to the second pack 102 without leaking to the content container 160 .
  • the reaction liquid passage 160 may be formed higher than the fold when the bottom 150 is folded upward. If the reaction liquid passage 160 is placed below the fold 152 , the bottom 150 is not completely stretched out. The pouch 100 can be stood only when the bottom 150 has to be stretched out as much as a predetermined distance. However, if the reaction liquid passage 170 is placed below the fold 152 , i.e. if the second sheet 120 and the third sheet 130 are adhered close by the bottom 150 , this interferes with stretching out the bottom 150 . Thus, the reaction liquid passage 160 is preferably formed above the fold 152 so as not to interfere with the bottom 150 that is largely changed in position.
  • At least one of the first sheet 110 and the fourth sheet 140 may include a reaction liquid inlet 180 through which the reaction liquid can be injected. If the reaction liquid inlet 180 is formed in the first sheet 110 , the reaction liquid is injected into the first pack 101 . If the reaction liquid inlet 180 is formed in the fourth sheet 140 , the reaction liquid is injected into the second pack 102 . Then, the injected reaction liquid moves to the other pack via the reaction liquid passage 170 . Since the reaction liquid is injected through the reaction liquid inlet 180 , the reaction liquid passage 170 is preferably placed below the reaction liquid inlet 180 so that the reaction liquid can flow to the other pack. Alternatively, the reaction liquid inlet 180 may be formed in both the first sheet 110 and the fourth sheet 140 so that the reaction liquid can be injected at both sides.
