The present invention relates to a thermal reaction pack unit for cooling or heating contents by means of a reaction of a reaction liquid and a reactant, the thermal reaction pack unit comprising: an accommodation pack; a reactant to be accommodated in the accommodation pack; a reaction liquid bag, which accommodates, in a sealing manner, a reaction liquid to be isolated from the reactant, the reaction liquid coming into contact with the reactant so as to cause a thermal reaction, is accommodated inside the accommodation pack, has a fixing edge part, of one side thereof, coupled to a support edge part of the accommodation part, and has a tearing strap formed by a pair of cutting lines, which are cut into different cutting lengths along the transverse direction at the fixing edge part while spaced, at cutting intervals, from the fixing edge part; and a tearing member connected to the tearing strap so as to be capable of pulling the tearing strap in the tearing direction, the tearing strap becoming farther from the fixing edge part. The thermal reaction pack unit of the present invention allows a water bag to be readily torn by the tearing member.

Abrégé

The present invention relates to a pouch comprising: a pouch main body having an accommodating space; a separating part for separating and partitioning the accommodating space into a content accommodating space and a heating unit accommodating space; one or more heating units comprising a water-permeable sheet and a non-water-permeable sheet so as to accommodate a thermal reactant for reacting with a reaction liquid, wherein the water-permeable sheet of the heating unit is arranged facing the separating part. Accordingly, the effectiveness of the heat generated by the heating unit of the pouch is improved, and the pouch provides the benefit of easing the use thereof by a user by minimizing the heat transferred to the user.

The present invention relates to a vertical pouch. According to an embodiment of the present invention, the vertical pouch comprises: heating elements which react with a reaction liquid to cause an exothermic reaction; a first pack in which a space capable of accommodating the heating elements is formed between a first sheet and a second sheet; a second pack in which a space capable of accommodating the heating elements is formed between a third sheet and a fourth sheet; a contents accommodation portion comprising the second sheet of the first pack, the third sheet of the second pack, and a bottom portion which connects the lower portions of the second sheet and the third sheet and is upwardly or downwardly folded; and a reaction liquid passage portion which communicates between the first pack and the second pack. Accordingly, the volume of a pouch is minimized when the pouch is stored, the pouch is stably erected so as to allow contents to be conveniently eaten when the pouch is used, heat transfer to the body of a user or the outside is minimized when an exothermic reaction occurs, and a reaction liquid is readily injected into the heating elements which exist at both sides of the pouch.
