Description

Pouches {POUCH}

The present invention relates to a pouch, and more particularly, to a pouch that can block foreign matter from penetrating into the temperature control housing for controlling the temperature of the temperature control target such as heating or cooling retort food.

In general, the temperature control pouch includes a receptacle for receiving a temperature-controlled substance such as a retort food, and a thermostat for heating or cooling a temperature-controlled substance contained in a container separate from the receptacle. And a reaction liquid for causing an exothermic or endothermic reaction with the regulator.

In order to control the temperature of the temperature-controlled material contained in the pouch, the user breaks a separate container containing the reaction liquid to react the reaction liquid with the temperature control body. The temperature of the temperature controlled product is controlled by the reaction of the reaction liquid and the temperature controller.

By the way, the conventional pouch can be unexpectedly generated by forming a reaction liquid bag containing a reaction liquid reacting with the temperature control to be easily broken.

On the other hand, if the temperature control space containing the temperature control body is opened, after the temperature control material is put into the pouch, the reaction liquid such as water may be introduced into the temperature control space in the sterilization process, it is necessary to prepare for this.

It is an object of the present invention to provide a pouch which can minimize the occurrence of unintended exothermic or endothermic reactions.

Another object of the present invention is to provide a pouch with an improved structure to block the introduction of foreign matter into the temperature control space during the sterilization process after the temperature control material.

Another object of the present invention is to provide a pouch which can prevent the reaction liquid remaining after the reaction from flowing out of the pouch when the pouch is turned upside down.

Means for Solving the Problems According to the present invention, a content accommodating part in which a content is accommodated; Is disposed on at least one of the front side and the rear side of the contents receiving portion is provided with a temperature regulator for heating or cooling the contents, the lower side than the upper end of the contents receiving portion may generate heat or endothermic reaction with the temperature regulator And a temperature control part including a temperature control space forming member which has a reaction liquid input part into which a reaction liquid can be input, and is disposed on at least one of the front side and the rear side of the contents accommodation part to form a temperature control space for accommodating the temperature control body. The reaction liquid input part includes: a first folding part in which the temperature control space forming member is folded inward or outward; It can be achieved by a pouch comprising a first break for breaking the first folded portion.

Here, the temperature control space forming member may further include a second folded portion folded to be expandable by water vapor generated by the exothermic reaction in the temperature control space.

In addition, the upper sealing portion for sealing the upper end of the contents receiving portion; A reaction liquid outflow prevention unit disposed between the upper sealing part and the first folding part to prevent the reaction liquid introduced into the temperature control space from flowing down; The second sealing part may be further disposed between the upper sealing part and the reaction liquid leakage preventing part to break the upper sealing part from the contents receiving part to open the contents receiving part.

The reaction liquid leakage preventing part may include a reaction liquid leakage preventing sealing part sealing the content receiving part and the temperature control space forming member along a transverse direction at a position spaced in the longitudinal direction from the first folded part. Can be.

Here, the reaction liquid of the amount corresponding to the amount of the temperature regulator is built-in and may further include a reaction liquid portion disposed in the temperature control space.

According to the pouch according to the present invention has the following effects.

First, when the reaction liquid is not embedded, the weight and volume of the pouch can be relatively reduced, so that it is easy to transport and store.

Second, when the reaction liquid is not embedded, it is possible to prevent the undesired exothermic or endothermic reaction from occurring during transportation and storage. Even if the reaction liquid is built in, even if the user does not artificially tear the reaction liquid envelope, it is possible to prevent the unexpected exothermic reaction from occurring because the reaction liquid is unlikely to leak out.

Third, in the process of sterilizing the pouch before and after the packaging of the temperature controlled material, such as retort food, it is possible to block foreign matter from penetrating into the temperature control space.

Fourth, the sealing operation can be easily performed when manufacturing the pouch.

Fifth, the reaction liquid can be easily introduced into the temperature control space in which the temperature control body is built by breaking the folded reaction liquid input part.

Sixth, when the temperature controlled by the exothermic or endothermic reaction resembles the temperature-controlled material contained in the contents receiving unit to the outer container, it is possible to prevent the reaction liquid remaining in the temperature control space to flow out of the pouch together. .

Seventh, the folded portion can accommodate the expansion pressure due to water vapor generated during the exothermic reaction.

Eighth, when the reaction liquid is embedded, it is relatively easy to transport and store because the optimum amount of the reaction liquid reacts with the temperature regulator.

Ninth, the optimal amount of the reaction liquid is built in, so that the user can arbitrarily generate the exothermic or endothermic reaction as compared to the reaction liquid. Thereby, the content can be heated or cooled effectively.

The contents (C) may include retort foods such as solid rice, bibimbap, liquid soup, soup, powdered milk, or pads containing drug ingredients for cold and hot packs or mask pads containing cosmetic ingredients. Of course, in addition to those listed above, if heating or cooling is required immediately, it may be variously adopted regardless of the type and shape. In addition to the retort food described above, foods that require sterilization to increase shelf life may correspond to the contents (C) regardless of the type or form.

The contents accommodating part 1100 forms a contents accommodating space SP1 in which the contents C are accommodated.

The contents accommodating part 1100 includes a first accommodating part film 1110 and a second accommodating part film 1120.

The first accommodating part film 112 and the second accommodating part film 114 may be provided as plastic films.

In more detail, the first accommodating part film 1110 and the second accommodating part film 1120 may be formed of plastic films such as PE (polyethylene), PP (polypropylene), and PET (polyethylene terephthalate). . Of course, in addition to the above materials may be made of a synthetic resin film of various materials.

As an example, the first accommodating part film 1110 may be a CPP film having a thickness of 60 μm (micrometer), an aluminum film having a thickness of 9 μm (micrometer), a nylon film having a thickness of 15 μm (micrometer), and a thickness of 60 μm ( Micrometer) CPP film may be a film laminated. Of course, this is only an example, it may be a laminated film of another material, and in some cases may be a film of a single material. The second accommodating part film 1120 may have the same material as that of the first accommodating part film 1110. Of course, if necessary, the second accommodating part film 1120 may be formed of a material different from that of the first accommodating part film 1110.

The contents accommodating space SP1 may be formed by sealing left and right ends SA2 and SA3 and a lower end SA4 of the first accommodating part film 1110 and the second accommodating part film 1120.

An upper end of the contents accommodating space SP1 may be opened to allow the contents C to be injected. After the contents C are introduced into the contents accommodating space SP1, an upper end of the contents accommodating space SP1 may be sealed. As a sealing method, a method of fusion bonding two films 1110 and 1120 by heat using a sealing bar or a method of fusion bonding two films 1110 and 1120 by applying ultrasonic waves or microwaves may be adopted. In addition, when the contents are not food or drink, the two films 1110 and 1120 may be sealed by an adhesive or an adhesive film. In addition, a variety of known sealing methods may be employed in addition to the above-described sealing method.

In some cases, when the contents C are solid food, cosmetic or therapeutic pads, the upper end of the contents accommodation space SP1 may not be sealed. In addition, a predetermined amount of food to be heated or cooled is added to the contents accommodating space SP1 of the pouch 1000, and then a reaction liquid is directly added to the temperature regulating space SP2 formed by the temperature adjusting part 1200. Even in the case, the upper end of the content accommodation space SP1 may not be sealed.

As shown in FIG. 2, the temperature adjusting part 1200 is disposed at the front side of the contents accommodating part 1100 to form the temperature adjusting space SP2. Of course, in some cases, the temperature control unit 1200 may be provided on the rear side in addition to the front side to form a temperature control space on both sides with the contents receiving unit 1100 therebetween.

The temperature control unit 1200, the temperature control body 1210 accommodated in the temperature control space (SP2); And a temperature regulating space forming member 1220 forming the temperature regulating space SP2 in which the exothermic or endothermic reaction occurs.

The temperature control body 1210 reacts with the reaction liquid (W in FIG. 3) introduced into the temperature control space SP2 to generate an exothermic or endothermic reaction. Here, the reaction liquid (W in FIG. 3) may include water.

The temperature regulator 1210 includes a reactant 1211 and a reactant accommodating portion 1213 that exothermic or endotherm react with the reaction liquid (W in FIG. 3). The reactant 1211 includes a heating element or an endothermic body that causes the exothermic or endothermic reaction.

The reactant 1211 may include at least one of calcium oxide (CaO), calcium hydroxide (Ca (OH) 2), magnesium chloride (MgCl ₂ ), iron (Fe), and aluminum (Al) as a heating element. . Here, if the reactant 1211 exothermically reacts with the reaction liquid W, the reactant 1211 may be substituted or changed with other materials in addition to those described above.

Meanwhile, the reactant 1211 may include at least one of ammonium nitrate (NH ₄ NO ₃ ), sodium acetate (CH ₃ COONa), and urea as a heat absorber. Of course, if the reactant 1211 is capable of endothermic reaction with the reaction liquid W, the reactant 1211 may be substituted or changed with other materials in addition to those described above.

The additive reactant receiver 1213 accommodates the reactant 1211. The reactant accommodating part 1213 may be provided as a nonwoven fabric capable of absorbing or permeating the reaction liquid (W). The reactant accommodating part 1213 may be changed to various materials as long as the reactant W may be absorbed or permeated.

The temperature regulating space forming member 1220 is disposed opposite to the first accommodating part film 1110 of the contents accommodating part 1100 to accommodate the temperature regulating body 1210 therebetween ( 134).

The temperature control space forming member 1220 may be provided as a transparent film so that the reaction liquid (W) and the temperature control body 1210 can be visually checked. Of course, the temperature control space forming member 1220 may be made of a transparent transparent resin film only a part that can be seen with the naked eye. Of course, whether visually identifiable is optional and may be provided as an opaque film in some cases.

The upper sealing area SA1 of the temperature control space forming member 1220 and the first accommodating part film 1110 may be sealed so that their upper ends coincide with each other. In some cases, unlike shown, the upper end of the temperature control space forming member 1220 is located lower than the upper end of the first accommodating part film 1110 and the upper end of the temperature control space forming member 1220 is It may be bonded to the first accommodating film 1110.

The temperature control space forming member 1220 may be provided with a plastic film such as PP, PE, or PET. For example, the temperature control space forming member 1220 may be a plastic film in which a PET film having a thickness of 12 μm (micrometer) and a CPP film having a thickness of 60 μm (micrometer) are laminated. Of course, this is only one example, it may be a laminated film or a single material film of a film of a variety of known materials.

Meanwhile, the temperature control space forming member 1220 is disposed below the upper end of the contents accommodating part 1110 and includes reaction liquid input parts 1230 and 1240 into which the reaction liquid (W in FIG. 3) can be injected. .

The reaction liquid input parts 1230 and 1240 may include a first folding part 1230 in which the temperature control space forming member 1220 is folded outwardly; And a first breaking portion 1240 for breaking the first folded portion 1230.

Here, the first folded portion 1230 may be folded inward, unlike shown in FIG. In this case, a portion of the first folded portion 1230 is exposed outward so that a user can take out the first folded portion 1230 which is folded inward before breaking the first folded portion 1230. You can also

As illustrated in FIG. 2, the first foldable part 1230 may protrude so that the end portion thereof gradually slopes downward. As a result, it is possible to prevent the remaining reaction liquid, which will be described later, from escaping to the outside through the broken first folded portion 1230.

The first breaking portion 1240 may include notches disposed at both edges of the first folded portion 1230. In some cases, the notch may be formed on only one side.

The first breaking portion 1240 may include a breaking groove (not shown) extending along the cutting direction instead of the notch shown in the drawing. The break groove (not shown) is not a through slit that completely passes through the temperature control space forming member 1220 so that foreign matter does not flow into the temperature control space SP2 through the break groove (not shown). It is preferable that the thickness of the temperature control space forming member 1220 is provided in a relatively thin groove shape.

On the other hand, the temperature control space forming member 1220 may further include a second folded portion 1250 to the outside to be expandable by water vapor generated by the exothermic reaction in the temperature control space (SP2). Here, the second folded portion 1250 may be omitted as necessary.

Hereinafter, a process of using the pouch 1000 according to the first embodiment will be described with reference to FIGS. 3 to 5.

First, as described above, the contents C may be input by the manufacturer, or may be directly input by the user to the open contents receiving unit 1100 of the pouch 1000. In the state in which the temperature controlled object C is accommodated in the content accommodating part 1100, the user breaks the first folded part 1230 using the first break part 1240.

As a result, as illustrated in FIG. 3, the first folded portion 1230 is separated into a first upper folded piece 1231 and a first lower folded piece 1233. As a result, the temperature control space SP1 is opened. The reaction liquid W is introduced between the separated first upper and first lower folded pieces 1231 and 1233.

As shown in Figure 4, the injected reaction liquid is exothermic or endothermic reaction with the temperature regulator 1210. Here, when an exothermic reaction occurs, water vapor is generated and the generated water vapor expands the first upper and upper first lower folded pieces 1231 and 1233 while expanding the second folded part 1250. It is discharged through the outside.

In this case, even when an abnormal situation in which the steam suddenly explodes in the exothermic process occurs, the second folded portion 1250 may be inflated to be buffered. As a result, the temperature regulating space forming member 1220 is not tolerated by water vapor pressure and is torn, or the temperature regulating space SP2 is opened at other sealing portions except for the reaction liquid input parts 1230 and 1240, thereby allowing the reaction liquid W to be opened. Can be prevented from flowing out.

In some cases, the user may want to take the contents (C) heated or cooled by an exothermic or endothermic reaction according to a separate external container (A). In this case, as shown in Figure 5, the reaction liquid (W1) remaining after the reaction in the temperature control space (SP2) is the top of the temperature control space forming member 1220 and the first receiving portion film 1110. It is blocked by the sealing area SA1 and does not flow out. As described above, the broken first folded portions 1231 and 1233 protrude inclined downward, so that when the pouch 1000 is inverted as shown in FIG. 5, the first folded portions 1231 and 1233 may be inverted. Since 1233 is inclined upward, it is possible to further prevent the reaction liquid W1 from flowing out.

Here, the temperature adjusting space forming member 1220 and the upper sealing area SA1 of the first accommodating part film 1110 serve as a reaction liquid leakage preventing part.

On the other hand, the reaction liquid was described as not being accommodated in the pouch 1000, in some cases it may be accommodated in a sealed form in the temperature control space (SP2) of the pouch (1000).

In more detail, as shown in Figure 6, the reaction liquid (W); A reaction liquid part 1300 including a reaction liquid bag 1310 for sealing the reaction liquid W may be disposed in the temperature control space SP2.

The reaction liquid bag 1310 includes an accommodating space part 1313 forming an accommodating space for accommodating the reaction liquid W; A reaction liquid discharge part 1311 capable of discharging the received reaction liquid W; And a cutout 1314 for cutting the upper end of the reaction liquid discharge part 1311. The reaction liquid discharge part 1311 may be formed to have a smaller width than the accommodating space part 1313. Thereby, the reaction liquid can be easily discharged toward a predetermined target.

The amount of the reaction liquid that optimally reacts with the temperature control body 1210 is determined. When a general user causes the reaction liquid to enter the reaction liquid into the temperature control space SP2, an arbitrary amount is added. It is possible that no exothermic or endothermic reactions will occur as originally designed.

Therefore, in some cases, it may be necessary to incorporate a reaction liquid portion 1300 containing an optimum amount of reaction liquid capable of causing a reaction with the temperature control body 1210 disposed in the temperature control space SP2. have.

The reaction liquid part 1300 may be disposed together with the temperature control body 1210 in the temperature control space SP2. In this case, the temperature control space SP2 may be sealed while the reaction liquid part 1300 and the temperature regulator 1210 are disposed together.

Since the reaction liquid part 1300 is not opened unless the user cuts the cutout 1314 artificially, the reaction liquid does not flow out of the reaction liquid bag 1310.

When the user briefly describes how to use the pouch in which the reaction liquid unit 1300 and the temperature controller 1210 are built together, the first breaker 1240 illustrated in FIG. The folding unit 1230 is broken to open the temperature control space SP2.

After removing the reaction liquid bag 1310 from the opened temperature control space SP2 and cutting the cutout portion 1314, the reaction liquid W embedded in the reaction liquid bag 1310 is heated at the temperature. Feed into the control space SP2.

As a result, an exothermic or endothermic reaction occurs in the temperature control space SP2, and the content C embedded in the content accommodating part 1110 is heated or cooled.

Since the reaction liquid is the same as the above-described pouch using process except taking out the reaction liquid unit 1300 having a built-in reaction, redundant description will be omitted.

On the other hand, the reaction liquid portion 1300 has been described as being accommodated in the temperature control space (SP2), but in some cases it may be attached to the outer surface of the pouch 1000 in a detachable state by an adhesive or the like. In addition to this, the reaction liquid part 1300 may be coupled to the pouch 1000 in various forms as long as it can be carried together with the pouch 1000.
