FIGs. 1 to 3 illustrate that the temperature control spaces S2, S3 are formed in front and back, but not limited thereto. As necessary, the temperature control spaces S2, S3 may be formed at only one side. - The
temperature controller 220 includes a secondfront film 221 coupled in the front of the contents-accommodatingsection 210 and forming the temperature control space 52 in a front side; and asecond back film 224 coupled in the back of the contents-accommodatingsection 210 and forming the temperature control space 53 in a back side. - The second
front film 221 and thesecond back film 224 made of a plastic film such as polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET). Besides, the secondfront film 221 and thesecond back film 224 may be made of well-known synthetic resin films of various materials. - Here, the temperature control spaces S2, S3 are isolated from the contents-accommodating space
- The front and back temperature control spaces S2, S3 can communicate with each other through a communication space S4. The communication space S4 may be formed by arranging the contents-accommodating
section 210 so that thelower end portion 211c of the contents-accommodatingsection 210 can be spaced apart from the lower end portion C1 of thetemperature controller 220. In this case, the lower end portion C1 of thetemperature controller 220 is a part where the respective lower end portions of the secondfront film 221 and thesecond back film 224 are coupled by ultrasonic waves or thermal welding. Of course, coupling between the plastic films may be achieved various well-known methods besides the foregoing ultrasonic waves or thermal welding. - Meanwhile, the contents-accommodating
section 210 and thetemperature controller 220 may be coupled with each other at left and right end portions C1, C2 by ultrasonic waves or thermal welding. - The
temperature controller 220 includes a plurality oftemperature control agents - As described above, if the temperature control spaces S2, S3 are formed at only one side between front and back sides, the
temperature control agents - Here, the
temperature control agents heating elements absorption fabrics heating elements - As necessary, the
absorption fabrics - Also, a heat absorption agent endothermically reacting with the liquid reactant may be used instead of the
heating elements - The heating element may include at least one among calcium oxide, calcium hydroxide, magnesium chloride, iron, and aluminum. Of course, the foregoing substances may be replaced or changed by other substances as long as it can react with the liquid reactant.
- The heat absorption agent may include at least one of ammonium nitrate (NH4NO3), sodium acetate and urea.
- Here, the plurality of
temperature control agents - As necessary, in the plurality of
temperature control agents temperature control agent 223 may include only the heating element, and the backtemperature control agent 225 may include only the heat absorption agent. In this case, the front and back temperature control spaces S2, S3 may not communicate with each other but isolated from each other with the contents-accommodating space S1 therebetween. - The
temperature controller 220 may further include aliquid reactant entrance 222 through which the liquid reactant is put into the temperature control spaces S2, S3. - The
liquid reactant entrance 222 is to put the liquid reactant capable of reacting with thetemperature control agents - The
liquid reactant entrance 222 is sealed up but openable in the sealingportion 230 to be described later. - Also, the
liquid reactant entrance 222 is arranged at a lower side of the contents-accommodatingsection 210 rather than an upper end thereof. That is, an upper edge of theliquid reactant entrance 222 is lower than the upper end of the contents-accommodatingsection 210 so that a user can easily check the position of theliquid reactant entrance 222 with his/here naked eyes. - The
liquid reactant entrance 222 may be formed as a partial upper end section G of the secondfront film 221 of thetemperature controller 220 is not coupled with the firstfront film 211. At this time, the secondfront film 221 of the remaining upper end section C3 may be permanently sealted up with the firstfront film 211. - Here, the drawings illustrate the
liquid reactant entrance 222 is formed in the partial upper end section G of the secondfront film 221. As necessary, theliquid reactant entrance 222 may be formed in the entire upper end section of the secondfront film 221. - Also, the height of the
liquid reactant entrance 222 from the lower end of the pouch may be relatively greater than that of the remaining section C3 of the secondfront film 221 from the lower end of the pouch. Of course, theliquid reactant entrance 222 may have the same height as the remaining section C3 of the secondfront film 221. - The
liquid reactant entrance 222 may include a grip portion extended frontward to be griped by a user's hand. Thus, a user can easily open theliquid reactant entrance 222. - Here, the grip portion 222a may be as shown in
FIG. 3 formed to be folded down from the firstfront film 211. - As necessary, instead of the grip portion 222a of
FIG. 3 , the upper end of the secondfront film 221 may be as shown inFIG. 4 provided as it is spaced from the contents-accommodatingsection 210, specifically from the firstfront film 211 by a predetermined space K. Thus, a user puts his/her fingers in the space K and broadens theliquid reactant entrance 222, thereby opening theliquid reactant entrance 222. - Meanwhile, the sealing
portion 230 seals up theliquid reactant entrance 222. Thus, it is possible to prevent foreign materials from entering theliquid reactant entrance 222 while the contents is put into and sterilized in the contents-accommodating section S1 of thepouch 200. Such sterilization is essential when a retort pouch is produced by putting stew, soup, boiled rice and the like instant foods into thepouch 200. - Accordingly, the
pouch 200 according to an exemplary embodiment facilitates the manufacture of the retort pouch. - As shown in
FIG. 3 , the sealingportion 230 may be provided between the secondfront film 221 and the firstfront film 211 at a side lower than the grip portion 222a of theliquid reactant entrance 222. - The sealing
portion 230 may be provided to allow opening between the firstfront film 211 and the secondfront film 221 when force of not less than a predetermined magnitude is applied thereto. In other words, if external force of not less than a predetermined magnitude is applied, the sealingportion 230 may open theliquid reactant entrance 222. Thus, if a user grips and then pulls the grip portion 222a by force of not less than a predetermined magnitude, theliquid reactant entrance 222 is opened. - A user puts the liquid reactant (for example, water) into the opened
liquid reactant entrance 222, thereby heating or cooling the contents accommodated in the contents-accommodating space S1. - In particular, it is convenient for a user because the
liquid reactant entrance 222 is easily opened to put the liquid reactant therein. - The sealing
portion 230 may include an adhesive or a double-sided tape. As necessary, the sealingportion 230 may be formed by fusing the firstfront film 211 and the secondfront film 221 through thermal welding or ultrasonic waves. At this time, the firstfront film 211 and the secondfront film 221 may be fused to such an extent as to be separated from each other when the sealingportion 230 receives external force of a predetermined magnitude. - Of course, the sealing
portion 230 may be varied as long as it can seal up the liquid reactant entrance and prevent foreign materials, such as liquid (e.g., water), from being introduced therein if there is no external force of not less than a predetermined magnitude. - Meanwhile, the
pouch 200 may further include a ziplock 260 to selectively seal up the upper portion of the contents-accommodatingsection 210. - The ziplock 260 includes a
female zipper 261 formed inside the firstfront film 211 and amale zipper 263 formed inside of thefirst back film 213. Of course, the positions of thefemale zipper 261 and themale zipper 263 may be exchanged. - Also, various well-known sealing means may be employed instead of the ziplock 260 as long as it can selectively seal up the contents-accommodating
section 210. - Meanwhile, the
pouch 200 may further include atransparent window section 210 can be determined by naked eyes through thetransparent windows - As shown in
FIG. 1 , thetransparent window 215 may be arranged between theliquid reactant entrance 222 and the upper end of the firstfront film 211. Through thetransparent window 215, contact between the firstfront film 211 and the contents accommodated therein is checked by naked eyes, and it is thus possible to determine whether a product is defective or not. For example, if solid food is put into the contents-accommodatingsection 210 and then the contents-accommodating space S1 is vacuumized, it is possible to determine by naked eyes through thetransparent window 215 whether there is a trouble in the vaccumization. - Meanwhile, the
transparent window 216 may be as shown inFIGs. 1 and2 formed in a lower portion of thepouch 200. If the contents accommodated in the contents-accommodatingsection 210 is liquid and the liquid leaks out because the contents-accommodatingsection 210 is defective, it is possible to determine by naked eyes through thetransparent window 216 of the lower portion whether the product is defective or not. To make it easier to determine through thetransparent window 216 of the lower portion whether the contents-accommodatingsection 210 is sealed up or not, a corresponding region of the secondfront film 221 formed with thetransparent window 216 may be transparently formed, but a corresponding region of the firstfront film 221 may be opaque. For example, the secondfront film 221 may be entirely made of a transparent film, while the firstfront film 221 may be entirely made of an opaque film. - Also, the
transparent window 217 formed in a vertical direction may be as shown inFIG. 1 formed at one side between left and right sides of thepouch 200 along a lengthwise direction. Thus, a user leans thepouch 200 and checks by his/her naked eyes through thetransparent window 217 whether the contents accommodated in the contents-accommodatingsection 210 leak out or not, thereby determining whether a product is defective or not. - The plurality of
transparent windows section 210 is surely isolated from the temperature control spaces S2, S3. If it is chedcked through the plurality oftransparent windows - The drawings show the plurality of
transparent windows transparent windows - Meanwhile, the foregoing description illustrates that the
liquid reactant entrance 222 is formed at only one side between the front and back sides, but not limited thereto. Alternatively, theliquid reactant entrance 222 may be formed at both the front and back sides. - Meanwhile, a
pouch 200a according to the second exemplary embodiment may as shown inFIG. 5 include a contents-accommodatingsection 210a, atemperature controller 220 and a sealingportion 230. - The contents-accommodating
section 210a of thepouch 200 according to the first exemplary embodiment has thelower end 211c spaced apart from the lower end of thetemperature controller 220 as shown inFIG. 3 . On the other hand, in thepouch 200a according to the second exemplary embodiment, as shown inFIG. 5 , the lower end of the contents-accommodatingsection 210a is extended to the lower end of thetemperature controller 220 so that the contents-accommodatingsection 210a and thetemperature controller 220 can be coupled with each other in a lower region by ultrasonic waves or thermal welding. - A
communication hole section 210a so that the front and back temperature control spaces S2, S3 can communicate with each other. Here, the edge of thecommunication hole communication hole - A
pouch 200b according to the third exemplary embodiment may as shown inFIGs. 6 and7 include a contents-accommodatingsection 210, atemperature controller 220 and a sealingportion 240. - According to the third exemplary embodiment, the contents-accommodating
section 210 and thetemperature controller 220 except the sealingportion 240 are the same as those of the first exemplary embodiment. - According to the third exemplary embodiment, the sealing
portion 240 may include anadhesive tape 240 to seal up the upper end of theliquid reactant entrance 222. Thus, it is possible to prevent foreign materials (in particular, liquid) from being introduced into the temperature control spaces S2, S3 while the contents are put into the contents-accommodating section S1 and sterilized after the upper end of the contents-accommodating section S1 is sealed up. - Meanwhile, the
adhesive tape 240 includes anextended portion 241 extended so that one side there of can be gripped. Thus, a user can easily put the liquid reactant into thepouch 200b by pulling theextended portion 241 and removing theadhesive tape 240. - A
pouch 200c according to a fourth exemplary embodiment includes a contents-accommodatingsection 210; atemperature controller 220; a sealingportion 230 and apouch stand 250 as shown inFIG. 8 . - The
pouch 200c according to the fourth exemplary embodiment allows the contents-accommodatingsection 210 to stand by itself without any separate standing device as compared with thepouches - The pouch stand 250 is coupled to a lower side of the
pouch 200c so that thepouch 200c can stand. - In more detail, one end of the
pouch stand 250 is coupled to the lower end portion of thesecond front film 221a, thereby forming a front lower edge. Also, the other end of thepouch stand 250 is coupled to the lower end of thesecond back film 224a, thereby forming a back lower edge spaced apart from the front lower edge. Thus, the lower edges of thepouch 200c are broadened so that thepouch 200c can stand by itself without any separate device. - Here, if it is desired to change the
pouch 200a as shown inFIG. 4 in a standable form, the pouch stand 250 may be interposed between the lower end of thefirst front film 211a and the lower end of thefirst back film 213a. - Meanwhile, the pouch stand 250 may include a
transparent window 253 through which the inside of thepouch 200c can be seen. In the case of thestandable pouch 200c according to the fourth exemplary embodiment, a bottom formed by the pouch stand 250 may have atransparent window 253 besides the plurality oftransparent windows transparent window 253 may be formed by making at least one region of the pouch stand 250 with a transparent substance. As necessary, the pouch stand 250 may be entirely made of a transparent substance. Thus, a user can determine whether a product is defective or not with his/her naked eyes through thetransparent window 253 formed on the bottom of thepouch 200c. - When the contents-accommodating
section 210 is filled with the contents, the lower portion of the contents-accommodatingsection 210 may be expanded toward the pouch stand 25. In more detail, the lower portion of the contents-accommodatingsection 210 is creased so that the contents-accommodatingsection 210 can expand toward the pouch stand 25 when the contents-accommodatingsection 210 is filled with the contents. - Also, the lower portion of the contents-accommodating
section 210 is arranged near to the inside of the pouch stand 25 so that both the pouch stand 25 and the contents-accommodatingsection 210 can expand toward the bottom supporting thepouch 200 by the weight of the contents accommodated in the contents-accommodatingsection 210. - A
pouch 200d according to a fifh exemplary embodiment as shown inFIG. 9 includes a contents-accommodatingsection 210b; atemperature controller 220; a sealingportion 230 and apouch stand 250. - According to the fifth exemplary embodiment, the contents-accommodating
section 210b may be formed by sealing up a firstfront film 211b, aninner bottom film 218 and afirst back film 213b. In more detail, one end and the other end of theinner bottom film 218 are respectively sealed and coupled to the lower end of the firstfront film 211b and the lower end of thefirst back film 213b, thereby forming the contents-accommodatingsection 210b. Theinner bottom film 218 surely secures a lower space of the contents-accommodatingsection 210b so that the contents-accommodating space S1 can be filled with more contents. -
FIG. 10 is a perspective view of a pouch according to the sixth exemplary embodiment,FIG. 11 is a section view, taken along line A2-A2 ofFIG. 10 ,FIG. 12 is a section view showing that the pouch shown inFIG. 11 is filled with the temperature controllable object, andFIG. 13 is a section view showing that a sealing portion is opened to put a liquid reactant into the temperature control space of the pouch shown inFIG. 11 . - As shown in
FIGs. 10 to 13 , apouch 100 according to the sixth exemplary embodiment includes anaccommodating section 110, atemperature controller 130 provided with atemperature control agent 131, a sealingportion 140, agrip portion 150, asupporter 160, a sealing-bar attachment-preventingportion 170 and a cuttingportion 180. Thepouch 100 according to the sixth exemplary embodiment does not include thetemperature control agent 131 and the liquid reactant W for the exothermic or endothermic reaction. That is, the liquid reactant W is put into the poutch 100 from the outside in order to control the temperature of the temperaturecontrollable object 10. - Here, the temperature
controllable object 10 includes various instant food such as the retort pouch. For example, the contents may include food such as boiled rice, Bibimbap, soup, stew or dry milk; a pad containing medicine for taking a hot massage or a cold massage, or a mask pad containing beauty ingredients. Besides, the contents may be varied as long as it has to be instantly heated or cooled. - The
accommodating section 110 includes a firstaccommodating section film 112 and a secondaccommodating section film 114. Anaccommodating space 116 for accommodating the temperaturecontrollable object 10 is formed between the firstaccommodating section film 112 and the secondaccommodating section film 114. Here, the firstaccommodating section film 112 and the secondaccommodating section film 114 may be made of a heat-resistant plastic film. - In more detail, the
accommodating section 110 may be made of the plastic film such as polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET). Of course, the firstaccommodating section film 112 and the secondaccommodating section film 114 constituting theaccommodating section 110 may be made of well-know synthetic resin films of various materials. - For example, the first
accommodating section film 112 may include a CPP film having a thickness of 60µm, an aluminum film having a thickness of 9µm, or a combination film between a nylon film having a thickness of 15µm and a CPP film having a thickness of 60µm. Of course, this is nothing but illustrative. The firstaccommodating section film 112 may include a combination film of various materials, or as necessary include a film of a single material. The secondaccommodating section film 114 may be made of the same material as that of the firstaccommodating section film 112. - The first
accommodating section film 112 and the secondaccommodating section film 114 form an envelope shape as the other side and both sides connecting one side and the other side are adhered and sealed so as to open one side. As the firstaccommodating section film 112 and the secondaccommodating section film 114 are adhered, theaccommodating space 116 accommodating the temperaturecontrollable object 10 is formed. Trough an opening side of theaccommodating section 110, the temperaturecontrollable object 10 is filled in theaccommodating space 116, and the opening side is sealed up by the sealing-bar attachment-preventingportion 170 to be described later after the temperaturecontrollable object 10 is completely filled. - The
temperature controller 130 may be formed at one side between both sides of theaccommodating section 110. Thetemperature control agent 131 is accommodated in between thetemperature controller 130 and the outer side of theaccommodating section 110, and exothermally or endothermally reacts with the liquid reactant w to be inserted, thereby heating or cooling the temperaturecontrollable object 10. - The
temperature controller 130 according to the sixth exemplary embodiment includes thetemperature control agent 131 arranged at least one side between front and back sides of theaccommodating section 110 and heating or cooling the temperature controllable object (i.e., the contents); and a temperature controlspace forming member 132 provided in a lower side of theaccommodating section 110 rather than an upper side thereof, having theliquid reactant entrance 136 through which the liquid reactant w is inserted, and forming atemperature control space 134 where the exothermic or endothermic reaction occurs. - The
temperature control agent 131 includes areactant 131b and areactant accommodating section 131a. According to the sixth exemplary embodiment, thetemperature control agent 131 is arranged at one side between both sides of theaccommodating section 110. Thetemperature control agent 131 may be arranged at a side facing the firstaccommodating section film 112. Thetemperature control agent 131 reacts with the liquid reactant w such as water inserted from the outside. - The
reactant 131b includes the heating element or the heat absorption agent in accordance with whether to heat or cool the temperaturecontrollable object 10 accommodated in theaccommodating section 110. Thereactant 131b may include at least one as the heating element among calcium oxide (CaO), calcium hydroxide (Ca(OH)2), magnesium chloride (MgCl2), iron (Fe) and aluminum (Al). Here, thereactant 131b may be replaced or changed by other substances as long as it can exothermally react with the liquid reactant w. - On the other hand, the
reactant 131b may include at least one as the heat absorption agent among ammonium nitrate (NH4NO3), sodium acetate (CH3COONa) and (urea). Of course, thereactant 131b may be replaced or changed by other substances as long as it can endothermally react with the liquid reactant w. - The
reactant accommodating section 131a accommodates thereactant 131b. Thereactant accommodating section 131a includes a body 131a1 and a partition 131a2. Thereactant accommodating section 131a is provided as an absorption fabric to quickly absorb the liquid reactant w. As necessary, thereactant accommodating section 131a may be made of not the absorption fabric but other substances. - The body 131a1 is provided to accommodate the
reactant 131b. Here, the body 131a1 according to an exemplary embodiment is partitioned into four accommodating regions by the partition 131a2. Thus, thereactant 131b is accommodated in each of the plurality of accommodating regions partitioned by the partition 131a2, thereby preventing thereactant 131b from being leaning by its own weight. Also, thereactant 131b is accommodated in each of the plurality of accommodating regions, and thus the dividedreactant 131b individually contacts the liquid reactant w, thereby making a temperature control reaction quickly. - The temperature control
space forming member 132 together with the firstaccommodating section film 112 forms thetemperature control space 134 to accommodate thetemperature control agent 131. Thetemperature control space 134 is a space where the exothermic or endothermic reaction occurs when the liquid reactant w is inserted, and has a margin space to accommodate the liquid reactant w in addition to thetemperature control agent 131. - Here, the temperature control
space forming member 132 may be made of a transparent synthetic resin film so that the liquid reactant w and thetemperature control agent 131 to be inserted can be checked by naked eyes. Of course, the temperature controlspace forming member 132 may be partially made of the transparent synthetic resin film checkable by naked eyes. Of course, checkability by naked eyes is optional, and thus an opaque film may be used as necessary. Thetemperature controller 130 may be provided smaller than theaccommodating section 110 so that an upper opening of theaccommodating section 110 for inserting the temperaturecontrollable object 10 can be exposed. According to an exemplary embodiment, the height of the temperature controlspace forming member 132 may be eight tenth with respect to the height of theaccommodating section 110. - The temperature control
space forming member 132 may have an upper end lower than that of the contents-accommodatingsection 110. - The temperature control
space forming member 132 may be made of the plastic film. For example, the temperature controlspace forming member 132 may be the plastic film where a PET film having a thickness of 12µm and a CPP film having a thickness of 60µm are combined. Of course, this is nothing but illustrative. Alternatively, the plastic film may be a combination film where films of various well-known substances are combined or a single material film. - Meanwhile, the
temperature controller 130 adjacent to the opening of theaccommodating section 110 includes a liquidreactant insertion portion 136 for opening and closing thetemperature control space 134 to insert the liquid reactant therethrough. The liquidreactant insertion portion 136 is coupled to the contents-accommodatingsection 110 by the sealingportion 140 to be described later, and seals up thetemperature control space 134. - The liquid
reactant insertion portion 136 may be spaced part from the sealingportion 140 or the firstaccommodating section film 112 when force of not less than a predetermined magnitude is applied for inserting the liquid reactant w in thetemperature control space 134. Thus, the upside of thetemperature control space 134 is opened so that the liquid reactant w can be inserted in thetemperature control space 134. - The sealing
portion 140 seals up theaccommodating section 110 and thetemperature controller 130, specifically, the liquidreactant insertion portion 136, thereby sealing up thetemperature control space 134. Here, the sealingportion 140 seals up theaccommodating section 110 and the liquidreactant insertion portion 136 with predetermined intensity of adhesion so that thetemperature control space 134 can be opened when force of not less than a predetermined magnitude is applied for spacing the liquidreactant insertion portion 136 apart from theaccommodating section 110. That is, when the liquidreactant insertion portion 136 is pulled by force of not less than a predetermined magnitude strong enough to overcome the adhesion, thetemperature control space 134 is opened. On the other hand, if force of not less than a predetermined magnitude is not applied, the sealing is maintained so that foreign materials including the liquid reactant cannot be introduced into thetemperature control space 134. - Here, the sealing
portion 140 may have an adhesive strength of not less than 200gf/cm2 and not more than 5kgf/ cm2. In experimental results, if the adhesive strength is less than 200gf/cm2, the sealing may not be maintained when the temperaturecontrollable object 10 is filled and then heated to expand thetemperature control space 134. On the other hand, the adhesive strength is more than 5kgf/cm2, it is difficult for a regular adult to open thetemperature control space 134. - Preferably, the sealing
portion 140 may have a adhesive strength of 500gf/cm2 ∼ 3kgf/cm2. - According to an exemplary embodiment, the sealing
portion 140 is placed on the planar surface of the firstaccommodating section film 112, and seals up between the liquidreactant insertion portion 136 of the temperature controlled 130and the firstaccommodating section film 112. Thus, the sealingportion 140 seals up between the firstaccommodating section film 112 and the liquidreactant insertion portion 136, and prevents foreign materials from being introduced into thetemperature control space 134 while the temperaturecontrollable object 10 is filled in theaccommodating space 116 of theaccommodating section 110 and then sterilized. Such sterilization is essential when a retort pouch is produced by putting stew, soup, boiled rice and the like instant foods into thepouch 100. - Meanwhile, the sealing
portion 140 may be released from the sealing with the liquidreactant insertion portion 136 when force of not less than a certain magnitude is applied for inserting the liquid reactant w into thetemperature control space 134 as temperature control is required for the temperaturecontrollable object 10. Then, the liquidreactant insertion portion 136 is opened to open thetemperature control space 134, so that the liquid reactant w can be inserted in thetemperature control space 134. Accordingly, the exothermic or endothermic reaction occurs between thetemperature control agent 131 and the liquid reactant w. - Here, the sealing
portion 140 may include at least one among liquid adhesive for adhereing the firstaccommodating section film 112 and the liquidreactant insertion portion 136, a solid adhesive tape, and an easy peel film provided between the firstaccommodating section film 112 and the liquidreactant insertion portion 136. - Here, the solid adhesive tape may be a film type tape, one or both sides of which the adhesive is applied to.
- The easy peel film couples both films thereof with predetermine thermal adhesion when heat of a predetermined temperature range is applied. Here, the coupling force or adhesion may be controlled by adjusting the temperature range of heat applied to the easy peel film.
- Here, the adhesive strength due to the sealing
portion 140 between theliquid reactant entrance 136 and theaccommodating section 110 is weaker than contact strength between the temperature controlspace forming member 132 and theaccommodating section 110 besides theliquid reactant entrance 136. - In more detail, the
liquid reactant entrance 136 is expected to be opened so as to insert the liquid reactant in thetemperature control space 134, and therefore the adhesive strength of the partial sealing portion C6 between theliquid reactant entrance 136 and theaccommodating section 110 may be weaker than the adhesive strength of the partial sealing portion C7 in a lateral edge between the temperature controlspace forming member 132 and theaccommodating section 110. This may be achieved by changing the temperature range of the sealing bar used when sealing the partial sealing portions C7, C6. Such temperature range will be described later. - Meanwhile, the
grip portion 150 is provided to grip the liquidreactant insertion portion 136 of thetemperature controller 130. Thegrip portion 150 is extended from the liquidreactant insertion portion 136 and formed integrally with the liquidreactant insertion portion 136. - The
grip portion 150 may protrude from the liquidreactant insertion portion 136. Thegrip portion 150 may be provided in a center region of the liquidreactant insertion portion 136. Thegrip portion 150 protrudes from the center region of the liquidreactant insertion portion 136 and is gripped by a user. In particular, thegrip portion 150 is gripped by a user and transfers a user's force to the liquidreactant insertion portion 136 so that the liquidreactant insertion portion 136 can be released from theaccommodating section 110. To make a user easily grip thegrip portion 150 and efficiently transfer his/her force, thegrip portion 150 may protrude from the center portion of the liquidreactant insertion portion 136. - Of course, the
grip portion 150 may be provided at both sides of the liquidreactant insertion portion 136. - The

Thesupporter 160 supports thetemperature control agent 131 in thetemperature control space 134 and prevents thetemperature control agent 131 from moving. That is, thesupporter 160 prevents thetemperature control agent 131 from moving during a distribution process of thepouch 100. Thesupporter 160 is not essential for thepouch 100, and may be omitted as necessary. - According to an exemplary embodiment, the
supporter 160 is placed on an inner side of the temperature controlspace forming member 132 and supports thetemperature control agent 131. Of course, thesupporter 160 may be placed on an outer side of the firstaccommodating section film 112 and support thetemperature control agent 131. Thesupporter 160 may be made of various adhesive materials such as the adhesive tape in order to support thetemperature control agent 131 against the temperature controlspace forming member 132. - Meanwhile, when the sealing-bar attachment-preventing
portion 170 seals up the upper ends of the firstaccommodating pack film 112 and the secondaccommodating pack film 114 by the sealing bar 131a2 having a predetermined sealing temperature in order to seal up the upper side of theaccommodating section 110, the firstaccommodating pack film 112 is attached to and not separated from the sealing bar. - In more detail, the first
accommodating pack film 112 is as described above made of a single CPP film or a combination film where the CPP film is exposed. The CPP film may be attached to and not well separated from the sealing bar, and to prevent this, the sealing-bar attachment-preventingportion 170 may be provided in theaccommodating section 110 contacting the sealing bar. - The PET substance may be used as a material not well attached to the sealing bar. The sealing-bar attachment-preventing
portion 170 may include a film of which a part exposed frontward is combined with the PET film, or a single PET film. - For example, the sealing-bar attachment-preventing
portion 170 may be the same plastic film as the temperature controlspace forming member 132, where the PET film having a thickness of 12µm and the CPP film having a thickness of 60µm are combined. Here, the PET film has to be arranged to be exposed frontward so that the PET film can contact the sealing bar. - Here, it is just illustrative that the PET is used as a material for the sealing-bar attachment-preventing
portion 170. The PET may be replaced by the plastic films of various well known materials as long as it cannot well attached to the sealing bar. - The cutting

- As shown in
FIG. 11 , since the firstaccommodating section film 112 and the secondaccommodating section film 114 exist in the cutting portion AA1 formed with the notch, it is thinner than three layered films of the sealing-bar attachment-preventingmember 170, and the first and secondaccommodating section films accommodating section 110. - Also, total four layered films of the temperature control
space forming member 132, the sealingportion 140, the firstaccommodating section film 112 and the secondaccommodating section film 114 exist below the cutting portion AA1, and therefore the cutting portion AA1 having total two layered films is relatively thin. Thus, the cutting portion AA1 can be more easily torn. - Meanwhile, the
supporter 160, the sealing-bar attachment-preventingportion 170 and the cuttingportion 180 described above are not essential, and all or a part of them 160, 170, 180 may be omitted as necessary. - Meanwhile, the foregoing illustrates that the lateral edges C7 of the first
accommodating section film 112 and the secondaccommodating section film 114 of theaccommodating section 110 are directly sealed up. As necessary, the cross section of the lateral edges may be creased like so that a user can more easily grip the lateral side of thepouch 100. This may be achieved by interposing a separate fim between the lateral edges of the firstaccommodating section film 112 and the secondaccommodating section film 114 and thus broadening both edges. -

space forming member 331, the edge region D1 is not being sealed but opened so that the temperature controllable object can be inserted through such an opend opening. - Next, after the temperature controllable object is completely inserted, the opened edge region D1 is thermally adhered by the sealing bar heated within the second temperature range.
- At this time, the predetermined second temperature range may be 230°C or higher and 300°C or lower.
- Meanwhile, the method of thermllay adhering the second temperature control
space forming member 332 to the secondaccommodating section film 114 and thesecond sealing portion 243 is the same as that for the first temperature controlspace forming member 332, and the repetitive descriptions thereof will be avoided. - Meanwhile, in the foregoing, the
temperature control agent 131 is inserted between the first temperature controlspace forming member 331 and thefirst sealing portion 241 and the edges D2, D3, D4 are sealed up, and then the temperature controllable object is filled in the accommodating space between the first and secondaccommodating section films - However, in the case where the edges D2, D3, D4 of the first and second
accommodating section films second sealing portions space forming members temperature control agent 131. Accordingly, the sealing work for the edges D2, D3, D4 may be performed once again. That is, the contents filling and sealing process and the temperature control agent filling and sealing process may be exchanged in order. - Here, if the temperature controllable object (i.e., the contents) is coffee, soup or the like liquid food needed to be sterilized, the contents filling and sealing processes may be previously performed to the temperature control agent filling the sealing process so as to make the contents filling process more safety.
- The sealing of the upper end edge D1 of the pouch may be performed after the temperature controllable object (i.e., the contents) is filled. As necessary, the upper end edge D1 may not be sealed if the temperature controllable object (i.e., the contents) is hardly affected by an external environment or if there is no need of sealing the contents-accommodating space because its expiration date is short.
- Meanwhile, a method of manufacturing the pouch will be described below with reference to
FIG. 18 to FIG. 21 and -
FIG. 29 . - First, the contents-accommodating
section 110 capable of accommodating the contents therein, the temperature controlspace forming member 132 arranged in at least one side between the front and back sides of the contents-accommodatingsection 110 and having the upper end lower than that of the contents-accommodating section, and at least one sealingportion 140 inserted between the temperature control space forming member and the contents-accommodating section are combined (S10). - Then, the upper end region of the temperature control
space forming member 132 with the sealingportion 140 is thermally adhered to the contents-accommodatingsection 110 by the sealing bar heated at the first temperature (S20). Here, the upper end region, which corresponds to theliquid reactant entrance 136 of the temperature controlspace forming member 132, seals up theliquid reactant entrance 136. - Here, the first temperature may be 150°C or higher and 220°C or lower. If the first temperature for heating the sealing bar to thermally adhere the upper end region is lower than 150°C, the thermal adhesive strength of the
liquid reactant entrance 136 is so weak that the sealing of thetemperature control space 134 is deteriorated between the temperature controlspace forming member 131 and the contents-accommodatingsection 110, thereby allowing foreign materials (e.g., moisture or the like) to be introduced. - On the other hand, if the first temperature is higher than 220°C, the thermal adhesive strength of the
liquid reactant entrance 136 is so strong that it is difficult for a user to open thetemperature control space 134. - Next, the
temperature control agent 131 is inserted in the temperature controlspace forming member 131 and the contents-accommodating section 140 (S30). - Next, the left and right sides and the lower sides of the temperature control
space forming member 132 filled with thetemperature control agent 131 are thermally adhered to the contents-accommodatingsection 110 by the sealing bar heated up to the second temperature (S40). - Here, the second temperature may be 230°C or higher and 300°C or lower.
- Here, the first temperature is lower than the second temperature. As described above, this is to make a user easily open the
temperature control space 134 while keeping its sealing as the thermal adhesive strength of theliquid reactant entrance 136 expected to be open is weaker than the other portions (i.e., the left, right and lower edges). - Meanwhile, the combination of S10 includes primarily sealing the left, right and lower edges of the contents-accommodating
section 110 and the sealingportion 140 so that the upper end of the contents-accommodatingsection 110 can be open, by combining the contents-accommodatingsection 110 and the sealing portion 140 (S11); and combining the temperature controlspace forming member 132 to the front side of the primarily sealed sealing portion 140 (S12). Thus, theaccommodating space 116 is formed to accommodate the temperaturecontrollable object 10 in the state that the upper end of the contents-accommodatingsection 110 is opend. - Here, in the primarily sealing (S11), only the contents-accommodating
section 110 may be combined and sealed without the sealingportion 140. In this case, the sealingportion 140 together with the temperature controlspace forming member 132 may be sequentially combined to the contents-accommodatingsection 110 in the combination (S12). - Meanwhile, the operation of putting the temperature
controllable object 10 in theaccommodating space 116 formed by the primarily sealing may be performed between the primarily sealing (S11) and the combination of the temperature control space forming member 132 (S12). - As necessary, the operation of putting the temperature
controllable object 10 may be peformed after the operation S40 of thermally adhering the left, right and lower end regions of the temperature controlspace forming member 132. - As shown in
FIG. 30 to FIG. 32 , a pouch 2100 according to the seventeenth exemplary embodiment includes atemperature controller 2130 provided with a contents-accommodatingsection 2110, atemperature control agent 2131 and aliquid reactant container 2190; a sealingportion 2140, agrip portion 2150 and apouch cutting portion 2180. - The contents-accommodating
section 2110 is provided to accommdate the contents, that is, the temperaturecontrollable object 10. - Here, Here, the temperature
controllable object 10 includes various instant food such as the retort pouch. For example, the contents may include food such as boiled rice, Bibimbap, soup, stew or dry milk; a pad containing medicine for taking a hot massage or a cold massage, or a mask pad containing beauty ingredients. Besides, the contents may be varied as long as it has to be instantly heated or cooled. - The contents-accommodating
section 2110 includes a firstaccommodating section film 2112 and a secondaccommodating section film 2114. Between the firstaccommodating section film 2112 and the secondaccommodating section film 2114 is formed anaccommodating space 2116 for accommodating the temperaturecontrollable object 10. Here, the firstaccommodating section film 2112 and the secondaccommodating section film 2114 may be made of a heat resistant plastic film. - In more detail, the contents-accommodating
section 2110 may include the plastic film such as polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET). - Of course, the first
accommodating section film 2112 and the secondaccommodating section film 2114 constituting the contents-accommodatingsection 2110 may be made of well-known synthetic resin films of various materials. - For example, the first
accommodating section film 2112 may include a CPP film having a thickness of 60µm, an aluminum film having a thickness of 9µm, or a combination film between a nylon film having a thickness of 15µm and a CPP film having a thickness of 60µm. Of course, this is nothing but illustrative. The firstaccommodating section film 112 may include a combination film of various materials, or as necessary include a film of a single material. The secondaccommodating section film 2114 may be made of the same material as that of the firstaccommodating section film 2112. - The first
accommodating section film 2112 and the secondaccommodating section film 2114 form an envelope shape as the other side and both sides connecting one side and the other side are adhered and sealed so as to open one side. As the firstaccommodating section film 2112 and the secondaccommodating section film 2114 are adhred, theaccommodating space 2116 accommodating the temperaturecontrollable object 10 is formed. Trough an opening side of theaccommodating section 2110, the temperaturecontrollable object 10 is filled in theaccommodating space 2116, and the opening side is sealed up by the sealing-bar attachment-preventingportion 2170 to be described later after the temperaturecontrollable object 10 is completely filled. - The
temperature controller 2130 may be formed at one side between both sides of theaccommodating section 2110. - The
temperature controller 2130 according to the seventeenth exemplary embodiment as shown inFIG. 30 to FIG. 32 andFIG. 34 includes thetemperature control agent 2131 arranged in atemperature control space 2134 provided in at least one side between front and back sides of the contents-accommodatingsection 2110 and heating or cooling the temperature controllable object (i.e., the contents); aliquid reactant container 2190 arranged in thetemperature control space 2134 and containing the liquid reactant for exothermically or endothermically reacting with thetemperature control agent 2131; and a temperature controlspace forming member 2132 forming thetemperature control space 2134 in which the exothermic or endothermic reaction occurs. - The
temperature control agent 2131includesthe reactant 2131b and thereactant accommodating section 2131a. Thetemperature control agent 2131 according to the seventeenth exemplary embodiment is arranged at one side between both sides of the contents-accommodatingsection 2110. Thetemperature control agent 2131 accordingto according to an exemplary embodiment is arranged at a side facing the firstaccommodating section film 2112. Thetemperature control agent 2131 reacts with the liquid reactant w such as water inserted from the outside. - The
reactant 2131b includes the heating element or the heat absorption agent in accordance with whether to heat or cool the temperaturecontrollable object 10 accommodated in theaccommodating section 2110. Thereactant 2131b may include at least one as the heating element among calcium oxide (CaO), calcium hydroxide (Ca(OH)2), magnesium chloride (MgCl2), iron (Fe) and aluminum (Al). Here, thereactant 131b may be replaced or changed by other substances as long as it can exothermally react with the liquid reactant w. - On the other hand, the
reactant 2131b may include at least one as the heat absorption agent among ammonium nitrate (NH4NO3), sodium acetate (CH3COONa) and (urea). Of course, thereactant 131b may be replaced or changed by other substances as long as it can endothermally react with the liquid reactant w. - The
reactant accommodating section 2131a accommodates thereactant 2131b. Thereactant accommodating section 131a includes a body 2131a1 and a partition 2131a2. Thereactant accommodating section 2131a is provided as an absorption fabric to quickly absorb the liquid reactant w. As necessary, thereactant accommodating section 2131a may be made of not the absorption fabric but other substances. - The body 2131a1 is provided to accommodate the
reactant 2131b. Here, the body 2131a1 according to an exemplary embodiment is partitioned into four accommodating regions by the partition 2131a2. Thus, thereactant 2131b is accommodated in each of the plurality of accommodating regions partitioned by the partition 2131a2, thereby preventing thereactant 2131b from being leaning by its own weight. Also, thereactant 2131b is accommodated in each of the plurality of accommodating regions, and thus the dividedreactant 2131b individually contacts the liquid reactant W1, thereby making a temperature control reaction quickly. - The temperature control
space forming member 2132, as shown inFIG. 30 , is arranged in a lower side rather than an upper end of the contents-accommodatingsection 2110. In more detail, the upper end of the temperature controlspace forming member 2132 is lower than the upper end of the contents-accommodatingsection 2110. - The temperature control
space forming member 2132 includes aliquid reactant entrance 2136 through which theliquid reactant container 2190 is taken out from thetemperature control space 2134 and the liquid reactant W1 contained in theliquid reactant container 2190 is put in. - The temperature control
space forming member 2132 together with the firstaccommodating section film 2112 forms thetemperature control space 2134 to accommodate thetemperature control agent 2131 and theliquid reactant container 2190. Thetemperature control space 2134 is a space where the exothermic or endothermic reaction occurs when the liquid reactant W1 contained in theliquid reactant container 2190 is inserted, and has a margin space to accommodate the liquid reactant W1 in addition to thetemperature control agent 2131. - Here, the temperature control
space forming member 2132 may be made of a transparent synthetic resin film so that the liquid reactant W1, theliquid reactant container 2190 and thetemperature control agent 131 to be inserted can be checked by naked eyes. Of course, the temperature controlspace forming member 2132 may be made of the transparent synthetic resin film with regard to only a part that can be checked by naked eyes. Of course, the temperature controlspace forming member 132 may be partially made of the transparent synthetic resin film checkable by naked eyes. Of course, checkability by naked eyes is optional, and thus an opaque film may be used as necessary. Thetemperature controller 2130 may be lower than theaccommodating section 2110 so that an upper opening of theaccommodating section 2110 for inserting the temperaturecontrollable object 10 can be exposed. According to an exemplary embodiment, the height of the temperature controlspace forming member 132 may be eight tenth with respect to the height of theaccommodating section 110. - The temperature control
space forming member 2132 may have an upper end lower than that of the contents-accommodatingsection 2110. - The temperature control
space forming member 2132 according to an exemplary embodiment may be arranged to have a height from the lower end of the contents-accommodatingsection 2110 to the upper end of the temperature controlspace forming member 2132, which is lower by 20% than the hight from the same position to the upper end of the contents-accommodatingsection 2110. - The temperature control
space forming member 2132 may be made of the plastic film. For example, the temperature controlspace forming member 132 may be the plastic film where a PET film having a thickness of 12µm and a CPP film having a thickness of 60µm are combined. Of course, this is nothing but illustrative. Alternatively, the plastic film may be a combination film where films of various well-known substances are combined or a single material film. - The
liquid reactant container 2190 as shown inFIG. 34 includes a liquidreactantthe accommodating section 2191 forming the accommodating space to accommodate the liquid reactant W1; aliquid reactant outlet 2193 through which the accommodated liquid reactant flows out; and a liquid reactantcontainer cutting portion 2195 for cutting theliquid reactant outlet 2193. - The
liquid reactant container 2190 may be made of soft or hard plastic film. According to an exemplary embodiment, theliquid reactant container 2190 may be an envelope made of a soft plastic film. As necessary, theliquid reactant container 2190 may be achieved by sealing a hard plastic film (or plate) and a soft plastic film with each other. - The
liquid reactant outlet 2193 may have a width narrower than the liquidreactantthe accommodating section 2191. Thus, through theliquid reactant outlet 2193 having a relatively narrow width, the liquid reactant W1 can easily flow out in a predetermined direction. - The liquid reactant
container cutting portion 2195 may include a notch formed at one side of theliquid reactant outlet 2193. The notch may be replaced by a cutting groove formed along the cutting direction. Besides, the notch may have various shapes as long as it can be cut with a hand gripping theliquid reactant outlet 2193. - The liquid reactant
container cutting portion 2195 may be cut when a user artificially applies shear force in a width direction with his/her two hands. Thus, it is possible to prevent the liquid reactantcontainer cutting portion 2195 from being cut by mistake while carrying the pouch 22100a. - The liquid
reactant insertion portion 2136 is coupled to the contents-accommodatingsection 2110 by the sealingportion 2140 to be described later, and closes thetemperature control space 2134. - Also, the liquid
reactant insertion portion 2136 is provided to open thetemperature control space 2134 closed by the sealingportion 2140 so that theliquid reactant container 2190 can be taken out and the liquid reactant W1 contained in theliquid reactant container 2190 can be put in. - In more detail, the liquid
reactant insertion portion 2136 can be spaced apart from the sealingportion 2140 or the firstaccommodating section film 2112 when force of not less than a predetermined magnitude is applied, in order to take out theliquid reactant container 2190 from thetemperature control space 2134 and put the liquid reactant W1 of theliquid reactant container 2190. Thus, the upper side of thetemperature control space 2134 is opened so that the liquid reactant W1 can be put in thetemperature control space 2134. - The sealing
portion 2140 seals up theaccommodating section 2110 and thetemperature controller 2130, specifically, the liquidreactant insertion portion 2136, thereby sealing up thetemperature control space 2134. Here, the sealingportion 2140 seals up theaccommodating section 2110 and the liquidreactant insertion portion 2136 with predetermined intensity of adhesion so that thetemperature control space 2134 can be opened when force of not less than a predetermined magnitude is applied for spacing the liquidreactant insertion portion 2136 apart from theaccommodating section 2110. That is, when the liquidreactant insertion portion 2136 is pulled by force stronger than the adhesive strength of the sealingportion 2140, thetemperature control space 2134 is opened. On the other hand, if force of not less than a predetermined magnitude is not applied, the sealing due to the sealingportion 2140 is maintained, thereby maintaining the sealed state of thetemperature control space 2134 - Here, the sealing
portion 2140 may have an adhesive strength of not less than 2200gf/cm2 and not more than 5kgf/ cm2. In experimental results, if the adhesive strength is less than 2200gf/cm2, the sealing may not be maintained when the temperaturecontrollable object 10 is filled and then heated to expand thetemperature control space 2134. On the other hand, the adhesive strength is more than 5kgf/cm2, it is difficult for a regular adult to open thetemperature control space 2134. - Preferably, the sealing
portion 2140 may have a adhesive strength of 500gf/cm2 ∼ 3kgf/cm2. - According to an exemplary embodiment, the sealing
portion 2140 is placed on the planar surface of the firstaccommodating section film 2112, and seals up between the liquidreactant insertion portion 136 of the temperature controller 130and the firstaccommodating section film 2112. Thus, the sealingportion 2140 seals up between the firstaccommodating section film 2112 and the liquidreactant insertion portion 2136, and prevents foreign materials from being introduced into thetemperature control space 134 while the temperaturecontrollable object 10 is filled in theaccommodating space 2116 of theaccommodating section 2110 and then sterilized. Such sterilization is essential when a retort pouch is produced by putting stew, soup, boiled rice and the like instant foods into the pouch 2100. - Meanwhile, the sealing
portion 2140 may be released from the sealing with the liquidreactant insertion portion 2136 when force of not less than a certain magnitude is applied for inserting the liquid reactant W1 into the temperature control space 1134 as temperature control is required for the temperaturecontrollable object 10. Then, the liquidreactant insertion portion 2136 is opened to open thetemperature control space 2134, so that the liquid reactant w can be inserted in thetemperature control space 2134. Accordingly, the exothermic or endothermic reaction occurs between thetemperature control agent 2131 and the liquid reactant W1. - Here, the sealing
portion 2140 may include at least one among liquid adhesive for adhereing the firstaccommodating section film 2112 and the liquidreactant insertion portion 2136, a solid adhesive tape, and an easy peel film provided between the firstaccommodating section film 2112 and the liquidreactant insertion portion 2136. - Here, the solid adhesive tape may be a film type tape, one or both sides of which the adhesive is applied to.
- The easy peel film couples both films thereof with predetermine thermal adhesion when heat of a predetermined temperature range is applied. Here, the coupling force or adhesion may be controlled by adjusting the temperature range of heat applied to the easy peel film.
- Here, the adhesive strength due to the sealing
portion 2140 between theliquid reactant entrance 2136 and theaccommodating section 2110 is weaker than contact strength between the temperature controlspace forming member 132 and theaccommodating section 2110 besides theliquid reactant entrance 2136. - In more detail, the
liquid reactant entrance 2136 is expected to be opened so as to insert the liquid reactant in thetemperature control space 2134, and therefore the adhesive strength of the partial sealing portion C10 between theliquid reactant entrance 2136 and theaccommodating section 2110 may be weaker than the adhesive strength of the partial sealing portion C9 in a lateral edge between the temperature controlspace forming member 2132 and theaccommodating section 2110. This may be achieved by changing the temperature range of the sealing bar used when sealing the partial sealing portions C9, C10. Such temperature range will be described later. - The upper end region of the temperature control
space forming member 2132 and the contents-accommodatingsection 2110 between which thesealing portion 2140 is interposed are may be thermally adhered by the sealing bar heated at the first temperature. Here, the upper end region, which corresponds to theliquid reactant entrance 2136 of the temperature controlspace forming member 2132, seals up theliquid reactant entrance 2136. - Here, the first temperature may be 150°C or higher and 220°C or lower. If the first temperature of the sealing bar thermally adhering the upper end regions is lwer than 150°C, the thermal adhesive strength of the
liquid reactant entrance 2136 is so weak that the sealability of thetemperature control space 2134 between the temperature controlspace forming member 2131 and the contents-accommodatingsection 2110 is deteriorated to thereby allowing external foreign materials (e.g., moisture or the like) to be introduced therein. - On the other hand, if the first temperature is higher than 220°C, the thermal adhesive strength of the
liquid reactant entrance 2136 is so strong that it is difficult for a user to open thetemperature control space 2134. - Meanwhile, the partial sealing portion C9 of the left, right and lower edge regions between the temperature control
space forming member 2132 and the contents-accommodatingsection 2110 may be thermally adhered by the sealing bar heated at the second temperature. - Here, the second temperature may be 230°C or higher and 2300°C or lower.
- Here, the first temperature is lower than the second temperature. As described above, this is to make a user easily open the
temperature control space 134 while keeping its sealing as the thermal adhesive strength of theliquid reactant entrance 136 expected to be open is weaker than the other portions (i.e., the left, right and lower edges). - Meanwhile, the
grip portion 2150 is provided to allow a user to easily grip the liquidreactant insertion portion 2136 of thetemperature controller 2130. Thegrip portion 2150 may be extended from the liquidreactant insertion portion 2136 and may be formed integrally with the liquidreactant insertion portion 2136. - The
grip portion 2150 may protrude from the liquidreactant insertion portion 2136. Thegrip portion 2150 may be provided in the center region of the liquidreactant insertion portion 2136. Thegrip portion 2150 protrudes from the center region of the liquidreactant insertion portion 2136 and is gripped by a user. In particular, thegrip portion 2150 is gripped by a user and transfers a user's force to the liquidreactant insertion portion 2136 so that the liquidreactant insertion portion 2136 can be released from theaccommodating section 2110. To make a user easily grip thegrip portion 2150 and efficiently transfer his/her force, thegrip portion 2150 may protrude from the center portion of the liquidreactant insertion portion 2136. - Of course, the
grip portion 2150 be plurally provided at both sides of the liquidreactant insertion portion 136. - As shown in
FIG. 31 , the upper end portions of the first and secondaccommodating section films controllable object 10 can be put into the contents-accommodatingsection 2110 along the inserting direction B1 in the state that the upper portion of the contents-accommodatingsection 2110 is opened. - To heat or cool the temperature
controllable object 10 accommodated in the contents-accommodatingsection 2110, as shown inFIG. 33 , a user first grips thegrip portion 2150 and pulls theliquid reactant entrance 2136 in a direction of Fl, thereby spacing it apart from theaccommodating section 2110. At this time, if force of not less than a predetermined magnitude is applied for spacing theliquid reactant entrance 2136 apart from theaccommodating section 2110, that is, stronger than the adhesive strength due to the sealingportion 2140, theliquid reactant entrance 2136 is opened. As described above, the thermal adhesive strength in the sealing region C10 due to the sealingportion 150 is weaker than the thermal adhesive strength of the edge portion C9 of theaccommodating section 2110, and therefore theliquid reactant entrance 2136 can be more easily opened than other portions. - In the state that the
temperature control space 2134 is being opened, theliquid reactant container 2190 is taken out from thetemperature control space 2134 and theliquid reactant container 2190 is cut using the liquid reactantcontainer cutting portion 2195 of theliquid reactant container 2190. From the cutliquid reactant container 2190, the liquid reactant is put into thetemperature control space 2134. Accordingly, the exothermic or endothermic reaction occurs between the liquid reactant and thetemperature control agent 2131 within thetemperature control space 2134, so that the temperaturecontrollable object 10 accommodated in theaccommodating space 2116 can be heated or cooled. As a proper amount of the liquid reactant contained in theliquid reactant container 2190 reacts with thetemperature control agent 2131, the optimal exothermic or endothermic reaction may occur. - After a lapse of predetermined time, a user uses the
grip portion 2180 to cut open the upper end of theaccommodating section 2110. Thus, a user takes in, takes out or uses the heated or coold temperaturecontrollable object 10 through theaccommodating section 2110 having the opened upper portion. - Meanwhile, the foregoing illustrates that the lateral edges D6 of the first
accommodating section film 2112 and the secondaccommodating section film 2114 of the contents-accommodatingsection 2110 are directly sealed up. As necessary, the cross section of the lateral edges may be creased like so that a user can more easily grip the lateral side of the pouch 2100. This may be achieved by interposing a separate fim between the lateral edges of the firstaccommodating section film 2112 and the secondaccommodating section film 2114 and thus broadening both edges. - A
pouch 2200 according to the eighteenth exemplary embodiment, as shown inFIG. 35 to FIG. 37 includes a contents-accommodatingsection 2210 having a contents-accommodating space S6 to accommodate the contents; atemperature controller 2220 provided in at least one side between the front and back sides of the contents-accommodatingsection 2210 to heat or cool the contents-accommodatingsection 2210; and a sealingportion 2230 sealing up aliquid reactant entrance 2222 communicating the temperature control spaces S7, S8 in thetemperature controller 2220. - The contents-accommodating
section 2210 includes a firstaccommodating section film 2211 and a secondaccommodating section film 2213 to form the contents-accommodating space S6. - The first
accommodating section film 2211 and the secondaccommodating section film 2213 may be made of a plastic film. In more detail, the plastic film may include polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET). Besides, the firstaccommodating section film 2211 and the secondaccommodating section film 2213 may be made of well-known synthetic resin films of various materials. - The
temperature controller 2220 couples with the contents-accommodatingsection 2210, in more detail, couples with the contents-accommodatingsection 2210 so as to form the temperature control spaces S7, S8 provided in at least one side between the front and rear sides with respect to the contents-accommodating space S6. -
FIG. 35 to FIG. 37 illustrate that the temperature control spaces S7, S8 are formed in front and back, but not limited thereto. As necessary, the temperature control spaces S7, S8 may be formed at only one side. - The
temperature controller 2220 includes asecond front film 2221 coupled in the front of the contents-accommodatingsection 2210 and forming the temperature control space S7 in a front side; and asecond back film 2224 coupled in the back of the contents-accommodatingsection 2210 and forming the temperature control space S8 in a back side. - The first temperature control
space forming member 2221 and the second temperature controlspace forming member 2224 may be made of a plastic film such as polyethylene (PE), polypropylene (PP), or a polyethyelene terephthalate (PET). Besides, the first temperature controlspace forming member 2221 and the second temperature controlspace forming member 2224 may be made of well-known synthetic resin films of various materials. - Here, the temperature control spaces S7, S8 are isolated from the contents-accommodating space S6.
- The front and back temperature control spaces S7, S8 can communicate with each other through a communication space S9. The communication space S9 may be formed by arranging the contents-accommodating
section 2210 so that thelower end portion 2211c of the contents-accommodatingsection 2210 can be spaced apart from the lower end portion D6 of thetemperature controller 2220. In this case, the lower end portion D6 of thetemperature controller 2220 is a part where the respective lower end portions of the first temperature controlspace forming member 2221 and the second temperature controlspace forming member 2224 are coupled by ultrasonic waves or thermal welding. Of course, coupling between the plastic films may be achieved various well-known methods besides the foregoing ultrasonic waves or thermal welding. - Meanwhile, the contents-accommodating
section 2210 and thetemperature controller 2220 may be coupled with each other at left and right end portions D6, D7 by ultrasonic waves or thermal welding. - The
temperature controller 2220 includes a plurality oftemperature control agents - As described above, if the temperature control spaces , S8 are formed at only one side between front and back sides, the
temperature control agents - Here, the
temperature control agents heating elements absorption fabrics heating elements - As necessary, the

heating elements - The heating element may include at least one among calcium oxide, calcium hydroxide, magnesium chloride, iron, and aluminum. Of course, the foregoing substances may be replaced or changed by other substances as long as it can react with the liquid reactant.
- The heat absorption agent may include at least one of ammonium nitrate (NH4NO3), sodium acetate and urea.
- Here, the plurality of
temperature control agents - As necessary, in the plurality of
temperature control agents temperature control agent 2223 may include only the heating element, and the backtemperature control agent 2225 may include only the heat absorption agent. In this case, the front and back temperature control spaces S7, S8 may not communicate with each other but isolated from each other with the contentsaccommodating space S6 therebetween. - The
temperature controller 2220 may further include theliquid reactant container 2190 arranged in the temperature control spaces S7, S8. - If the temperature control spaces S7, S8 communicate with each other, the
liquid reactant container 2190 may be provided in only the temperature control space S7 formed with theliquid reactant entrance 2222 to be described later. If theliquid reactant entrances 2222 are respectively formed at both sides of the plurality of temperature control space S7, S8, theliquid reactant container 2190 may be provided in each of the temperature control spaces S7, S8. - The
temperature controller 2220 may further include theliquid reactant entrance 2222 through which theliquid reactant container 2190 is taken out from the temperature control spaces S7, S8 and the liquid reactant (refer to W1 ofFIG. 34 ) of theliquid reactant container 2190 is put in. - The
liquid reactant entrance 2222 is sealed up by the sealingportion 2230 so as to be openable. - Also, the
liquid reactant entrance 2222 is arranged at a lower side of the contents-accommodatingsection 2210 rather than an upper end thereof. That is, an upper edge of theliquid reactant entrance 2222 is lower than the upper end of the contents-accommodatingsection 2210 so that a user can easily check the position of theliquid reactant entrance 2222 with his/here naked eyes. - The
liquid reactant entrance 222 may be formed as a partial upper end section G1 of the first temperature controlspace forming member 2221 of thetemperature controller 2220 is not coupled with the firstaccommodating section film 2211. At this time, the first temperature controlspace forming member 2221 of the remaining upper end section D8 may be permanently sealted up with the firstaccommodating section film 2211. - Here, the
liquid reactant entrance 222 the partial upper end section G of the secondfront film 221. As necessary, theliquid reactant entrance 222 may be formed in the entire upper end section of the secondfront film 221. - Here, the drawings illustrate the
liquid reactant entrance 2222 is formed in the partial upper end section G1 of the first temperature controlspace forming member 2221. As necessary, theliquid reactant entrance 222 may be formed in the entire upper end section of the first temperature controlspace forming member 2221. - Also, the height of the
liquid reactant entrance 2222 from the lower end of the pouch may be relatively greater than that of the remaining section D8 of the first temperature controlspace forming member 2221 from the lower end of thepouch 2200. Of course, theliquid reactant entrance 2222 may have the same height as the remaining section D8 of the first temperature controlspace forming member 2221. - The
pouch 2200 may include agrip portion 2222a extended frontward so that a user cen easily grip theliquid reactant entrance 2222 with his/her hand. Thus, a user can easily grip and open theliquid reactant entrance 2222. - Here, the
grip portion 2222a may be as shown inFIG. 37 formed to be folded down from the firstaccommodating section film 2211. - As necessary, instead of the
grip portion 2222a ofFIG. 37 , the upper end of the first temperature controlspace forming member 2221 may be provided as it is spaced apart from the contents-accommodatingsection 2210, specifically from the firstaccommodating section film 2211 by a predetermined space K. Thus, a user puts his/her fingers in the space and broadens theliquid reactant entrance 2222, thereby opening theliquid reactant entrance 2222. - Meanwhile, the sealing
portion 2230 seals up theliquid reactant entrance 2222 as long as theliquid reactant entrance 2222 is not spaced from the contents-accommodatingsection 2210 by force of not less than a predetermined magnitude. Thus, it is possible to prevent foreign materials from entering theliquid reactant entrance 2222 while the contents is put into and sterilized in the contents-accommodating section S6 of thepouch 2200. Such sterilization is essential when a retort pouch is produced by putting stew, soup, boiled rice and the like instant foods into thepouch 2200. - Accordingly, the
pouch 2200 according to an exemplary embodiment facilitates the manufacture of the retort pouch. - As shown in
FIG. 37 , the sealingportion 2230 may be provided between the first temperature controlspace forming member 2221 and the firstaccommodating section film 2211 at a side lower than thegrip portion 2222a of theliquid reactant entrance 2222. - The sealing
portion 2230 may be provided to allow opening between the firstaccommodating section film 2211 and the first temperature controlspace forming member 2221 when force of not less than a predetermined magnitude is applied thereto. In other words, if external force of not less than a predetermined magnitude is applied, the sealingportion 2230 may open theliquid reactant entrance 2222. Thus, if a user grips and then pulls thegrip portion 2222a by force of not less than a predetermined magnitude, theliquid reactant entrance 2222 is opened. - A user takes out and cuts the
liquid reactant container 2190 from the openliquid reactant entrance 2222, and puts the liquid reactant (refer to W1 ofFIG. 34 , for example, water) into the temperature control space S7, thereby heating or cooling the contents accommodated in the contents-accommodating space S6. - Here, the liquid reactant (refer to W1 of
FIG. 34 ) put into the temperature control space S7 causes the exothermic or endothermic reaction while moving to another temperature control space S8 through the communication space S9. - Also, since the
liquid reactant entrance 2222 is easily opened to put the liquid reactant, it is convenient for a user. - The sealing
portion 2230 may be made of the same material as the sealingportion 2140 of the foregoing seventeenth exemplary embodiment. In more detail, the sealingportion 2230 may include at least one among liquid adhesive, a solid adhesive tape, and an easy peel film arranged between the firstaccommodating section film 2112 and the liquidreactant insertion portion 2136. - As necessary, the sealing
portion 2230 may be formed by fusing the firstaccommodating section film 2211 and the first temperature control space forming member through thermal welding or ultrasonic waves. At this time, the firstaccommodating section film 2211 and the first temperature controlspace forming member 2221 may be fused to such an extent as to be separated from each other when the sealingportion 2230 receives external force of a predetermined magnitude. - Of course, the sealing
portion 2230 may be varied as long as it can seal up the liquid reactant entrance and prevent foreign materials, such as liquid (e.g., water), from being introduced therein if there is no external force of not less than a predetermined magnitude. - Meanwhile, the
pouch 2200 may further include a ziplock 2260 to selectively seal up the upper portion of the the contents-accommodatingsection 2210. As necessary, the ziplock 2260 may be omitted. - The
ziplock 2260 includes afemale zipper 2261 formed inside the firstaccommodating section film 2211 and amale zipper 2263 formed inside of the secondaccommodating section film 2213. of course, the positions of thefemale zipper 2261 and themale zipper 2263 may be exchanged. - Also, various well-known sealing means may be employed instead of the ziplock 2260 as long as it can selectively seal up the contents-accommodating
section 2210. - Meanwhile, the
pouch 2200 may further include atransparent window section 210 can be determined by naked eyes through thetransparent windows - As shown in
FIG. 35 , thetransparent window 2215 may be arranged between theliquid reactant entrance 2222 and the upper end of the firstaccommodating section film 2211. Through thetransparent window 2215, contact between the firstaccommodating section film 2211 and the contents accommodated therein is checked by naked eyes, and it is thus possible to determine whether a product is defective or not. For example, if solid food is put into the contents-accommodatingsection 2210 and then the contents-accommodating space S6 is vacuumized, it is possible to determine by naked eyes through thetransparent window 2215 whether there is a trouble in the vaccumization. - Meanwhile, the
transparent window 216 may be as shown inFIG. 35 andFIG. 36 formed in a lower portion of thepouch 2200. If the contents accommodated in the contents-accommodatingsection 2210 is liquid and the liquid leaks out because the contents-accommodatingsection 2210 is defective, it is possible to determine by naked eyes through thetransparent window 2216 of the lower portion whether the product is defective or not. To make it easier to determine through thetransparent window 2216 of the lower portion whether the contents-accommodating section 2310 is sealed up or not, a corresponding region of the the first temperaturespace forming member 2221 formed with thetransparent window 2216 may be transparently formed, but a corresponding region of the first temperaturespace forming member 2221 may be opaque. For example, the first temperaturespace forming member 2221 may be entirely made of a transparent film, while the firstaccommodating section film 2211 may be entirely made of an opaque film. - Also, the
transparent window 2217 formed in a vertical direction may be as shown inFIG. 35 formed at one side between left and right sides of thepouch 2200 along a lengthwise direction. Thus, a user leans thepouch 2200 and checks by his/her naked eyes through thetransparent window 2217 whether the contents accommodated in the contents-accommodatingsection 2210 leak out or not, thereby determining whether a product is defective or not. - The plurality of
transparent windows section 2210 is surely isolated from the temperature control spaces S7, S8. If it is chedcked through the plurality oftransparent windows - The drawings show the plurality of
transparent windows transparent windows - Meanwhile, the foregoing description illustrates that the
liquid reactant entrance 2222 is formed at only one side between the front and back sides, but not limited thereto. Alternatively, theliquid reactant entrance 222 may be formed at both the front and back sides. - The
pouch 2200a according to the nineteenth exemplary embodiment as shown inFIG. 38 andFIG. 39 includes the contents-accommodatingsection 2210; thetemperature controller 2220 and a sealingportion 2240. - The nineteenth exemplary embodiment is the same as the eighteenth exemplary embodiment except that the
ziplock 2260 is omitted and the sealingportion 2240 is arranged in a different position. - The sealing
portion 2240 of the nineteenth exemplary embodiment may includes anadhesive tape 2240 attached to the upper end outside of theliquid reactant entrance 2222 and sealing up the temperature control space S7. Thus, it is possible to prevent foreign materials (in particular, liquid) from being introduced into the temperature control spaces S7, S8 while contents are put into the contents-accommodating section S6 and sterilized after the upper end of the contents-accommodating section S6 is sealed up. - Meanwhile, the
adhesive tape 2240 includes atape grip portion 2241 extended so that its one side can be gripped. Thus, if a user pulls thetape grip portion 2241 and removes theadhesive tape 2240, the liquid reactant of theliquid reactant container 2190 accommodated in the temperature control space S7 can be easily put into the pouch 2200b. - A
pouch 2300 according to a twentieth exemplary embodiment as shown inFIG. 40 includes a contents-accommodating sectionaccommodating section 2110; atemperature controller 2330 provided with a plurality oftemperature control agents 2131 respectively arranged in a firstaccommodating section film 2112 and a secondaccommodating section film 2114; a sealingportion 2140 sealing up the plurality oftemperature control spaces temperature control agents 2131 and the plurality ofliquid reactant container 2190; and apouch stand 2790 arranged in lower portions of the firstaccommodating section film 2112 and the secondaccommodating section film 2114 and allowing thepouch 2300 to stand. - The

FIG. 41 , the sealing-bar attachment-preventingmember 2170 and the liquidreactant insertion portion 2237 may be spaced apart from each other so that a cutting region A7 where the pouch cutting portion (refer to 2180 inFIG. 30 ) with the notch is provided can be relatively thin. - That is, the cutting region A7 includes only the first
accommodating section film 2112 and the secondaccommodating section film 2114, and it is therefore thinner than three layered films of the sealing-bar attachment-preventingmember 170, the first and secondaccommodating section films section 2110. - Also, total four films of the temperature control
space forming member 2231, the sealingportion 2140, the firstaccommodating section film 2112 and the secondaccommodating section film 2114 are provided under the cutting region A7, and therefore the cutting region A7 having two layered films is relatively thin. Thus, the contents-accommodatingsection 2110a can be more easily cut by the pouch cutting portion (see 2180 inFIG. 30 ) formed in the cutting region A7. - To heat or cool the temperature controllable object, a user grips the
grip portion 2150 and applies force to theliquid reactant entrance 2237, thereby opening the firsttemperature control space 2234. Further, theliquid reactant container 2190 is taken out and cut from the open firsttemperature control space 2234, and the liquid reactant is inserted in the opened firsttemperature control space 2234. The liquid reactant put into the firsttemperature control space 2234 is introduced into a secondtemperature control space 235 through a communication space H1 between the liquid reactant theaccommodating section 2110 and thepouch stand 2790. Thus, the exothermic or endothermic reaction can occur between the liquid reactant and thetemperature control agent 2131 within even the secondtemperature control space 2235. - In the case of the
pouch 300b according to the twenty-first exemplary embodiment, even though a user opens not both thetemperature control spaces - Meanwhile, the sealing-bar attachment-preventing
