Portable Heating Package and a Manufacture Method Using the Same}

The present invention relates to a portable heating package, and more particularly, to form a plurality of receiving space by overlapping a thin plate having heat resistance several times and to include a heating material in a portion thereof by using heat generated in the exothermic reaction of the heating material in use It's about a package that can warm objects easily.

A common heating package contains a FRH (Flameless Ration Heater), a combat food heater that can heat and eat food in US military combat food. The FRH is prepared by mixing metal corrosion-resistant alloy powder, electrolyte material and filler with polyethylene powder and sintering at 150-180 ° C. to form a pad, and then covering it with a porous packaging cover and sealing it with aluminum or polyethylene bags. It is. If you use it, open a sealed bag and pour a small amount of water into the opening. Then, the water passes through the porous wrapper, causing an exothermic reaction with the internal heating material. will be.

However, since the porous packaging cover of the heating package discharges fine particles which are reaction by-products, it is not possible to put food directly inside the package and is used in contact with a separate packaged food or lunch box, and for this reason, the loss of heat generated in the exothermic reaction is reduced. Occurs, there is a problem that you need to further charge the heating material by the heat lost.

As a method for minimizing the heat loss, there is a method of molding a pack containing exothermic alloy powder on one surface by using plastic or board, but the method is difficult to apply in various forms due to lack of flexibility of the product. There is a disadvantage that the portability and portability is reduced.

Is shown.

As shown in Figures 2 and 4, the manufacturing method of the present invention is the first coating step (11) in which the thin plate 2 long in one direction is interviewed by the guide roll 6, and the two-layer thin plate interviewed A heat fusion step 12 of forming a “c” shaped junction portion 5a having an opening at a lower portion thereof by using a first rolling roll 61 having protrusions to form a heat generating space 32 in the heat generating chamber, and the heat A second coating step 14 for further interviewing the thin plates 2 on the upper and lower surfaces of the fused thin plates; Bonding step (15) for attaching the edge in the longitudinal direction (5b) using the second rolling roll (62) to form the accommodating space (31) in the four-ply thin plate; A snowmaking step 16 of inserting a heating material 4 into the heating space 32 formed in the thermal fusion step; The lower portion of the four-ply thin plate including the heat generating material is heat-sealed using a third rolling roll 63 to seal 5c.

In addition, a pyramid shape or a comb-tooth pattern is further formed on the surface of the first rolling roll 61 used in the thermal fusion step 12 to form the joint portion 5a on the thin plate and simultaneously form the guide line 23. The line generation step 13 is performed at the same time.

The heating package 1 manufactured by the above method has a rectangular outer shell 21a and 21b, a pair of inner shells 22a and 22b for dividing the inner portion of the outer shell, and pyramidal or comb-shaped patterns on the two inner surfaces. The guide line 23 formed by fusion of a constant inclination of the space, and the space portion (3) formed with two receiving spaces 31 and one heating space 32 by the endothelial is inserted into the space portion 3 It is composed of a heating material (4).

It is preferable to use a material having a good thermal insulation effect and flexibility and durability of the outer shell (21a, 21b), the inner shell (22a, 22b) is preferred to use a material having high flexibility and high thermal conductivity preferentially, The most representative one is the processing of aluminum foil, in addition to the general packaging material or film is used, the thermal conductivity and heat resistance is strong, does not release environmental hormones, any packaging material approved by the US FDA can be used.

In addition, the two endothelial surfaces (22a, 22b) is formed with a guide line 23 is fused to a certain slope of the surface is characterized in that the inclined line of the guideline is formed convexly upwards. When the heating package is upside down serves to prevent the heating material (4) contained in the lower portion of the heat generating space 32 to move to the top and to prevent the fine particles after the chemical reaction to flow out to the top, The heat generated during the reaction is contained in the groove of the guide line to delay the heat release time. Since the gap between the guide line and the other guide line is narrow, the water (H) injected into the cutting surface reacts with the exothermic material at a constant speed. By controlling the reaction rate, the heat emitted from the reaction is kept constant so that the food can be evenly heated.

On the other hand, in order to use the heating package 1 of the present invention, the upper portion of the heating package should be cut, and cutting the end portion of the upper two receiving spaces 31 divided into endothelial sections 22a and 22b therein. And a heating space 32 containing the heating material 4 is formed between the two receiving spaces, so that the food to be heated is directly inserted into the two receiving spaces 31 or a food packed pack is inserted and the heating space is provided. A small amount of water (H) may be added to (32).

When a small amount of water (H) is injected into the upper surface opened as shown in Figure 5a flows into the lower portion by the weight of water, flows along the inclined surface of the guide line 23 formed in the heat generating space (32), Since the gap 24 between the guide lines is narrowly formed, the injected water (H) is constantly input to the heating material 4 positioned below, so that heat can be obtained for a long time with a small amount of heating material.

In addition, another manufacturing method of the above-mentioned heating package is that the space portion is formed in the order of heat generation + accommodation + heat generation, Figure 9a, 9b, 9c, 9d. As shown in 9e, two thin plates having shorter lengths are formed on a thin plate having one long direction, and the edges are fused to fold left and right about a tangent line.

The folded three-ply thin plate is completed by inserting a heat generating material into the opening where the lower part of the two thin plates overlap and sealing the lower part and the side part.

One example of the formation of the above-mentioned space portion 3 is in the order of acceptance + heat generation + acceptance, but in the manufacturing method of the present invention by further performing a contacting step, the order or acceptance of accommodation + heat generation + accommodation + accommodation + heat generation + accommodation, etc. It can be carried out in various ways such as forming a space arrangement such as + heating + accommodation + heating + accommodation.

In addition, the shape of the above-mentioned guideline may also be implemented in various modifications as shown in Figure 7a, 7b, 7c, the embodiment according to the present invention is not limited to the above-described, it is common knowledge with respect to the present invention Various alternatives, modifications, and changes may be made to the extent apparent to those having the right to do so.

The heating package of the present invention is formed in the inner space that divides the compartment, the inner space of the three spaces formed by the inner space in the middle space or both spaces using the heat generating space and the remaining space as the receiving space It is to insert the object to be heated, such as food in the receiving space.

The guidelines formed by thermally fusion of two thin plates forming a heat generating space prevent the movement of the heat generating material at the bottom of the heat generating space to the upper portion and prevent the fine particles from flowing out to the upper portion, and the heat generated during the chemical reaction. In the groove of the guideline to delay the heat release time, and because the gap between the guideline and the other guideline is narrow, the amount of water injected into the cutting surface reacts with the heating material at a constant rate so that the temperature of the heat dissipated is constant. It keeps food warm evenly.

In addition, it is easy to carry because the material of the outer skin and the inner skin is flexible, and it is possible to install additional coating step in the manufacturing method to form an additional storage space, thereby providing an environmentally friendly heating package that reduces production costs and improves practicality. This will be possible.
