Standing pouch

摘要

A standing pouch includes an external pack, and an internal pack which is disposed in the external pack to form a first temperature control space and a second temperature control space which are spaced from each other, to form a contents accommodating space between the first temperature control space and the second temperature control space to accommodate contents. The first temperature control space can communicate with the second temperature control space. A first temperature control member and a second temperature control member are respectively disposed in the first temperature control space and the second temperature control space, and at least one of the first temperature control space and the second temperature control space have an open upper side to put a reactant liquid reacting with the first and second temperature control members to generate an exothermic or endothermic reaction.

1. A standing pouch comprising:
a first pack which comprises a first internal part and a second internal part; an accommodating space formed between the first internal part and the second internal part and configured to received and contain contents therein; a first external part which is disposed to face the first internal part to form a first temperature control space between the first external part and the first internal part; and a first temperature control member which is disposed in the first temperature control space, a first upper sealed part configured to seal an upper end of the first internal part and an upper end of the first external part to each other to close the first temperature control space; and a bottom external part sealing and coupled with a lower part of the first internal part and a lower part of the second internal part so that the lower part of the first internal part is spaced from the lower part of the second internal part, wherein the first upper sealed part is configured to be opened to allow an external reactant liquid to enter into the first temperature control space and react exothermically or endothermic ally with the first temperature control member disposes in the first temperature control space, the exothermic or endothermic reaction within the first temperature space configured to increase or decrease a temperature of contents within the accommodating space, wherein a first surface of the bottom external part is coupled with a lower internal surface of the first internal part and a lower internal surface of the second internal part respectively, so that a plane connecting between a lower end of the first internal part and a lower end of the second internal part is at least partially spaced apart from a second surface of the bottom external part, wherein the bottom external part is a discrete component separate from the first internal part and the second internal part, and coupled with a lower part of the first internal part and a lower part of the second internal part so as to be convex from a bottom surface on which the standing pouch is placed, wherein the bottom external part in combination with the first internal part and the second internal part define the accommodating space configured to receive and contain the contents to be heated or cooled.
