Abstract

PURPOSE:To provide an instantaneous cooling pack capable of cooling uniformly and efficiently, by a construction wherein a pack body is divided into two holding sections, in each of which each of materials to be mixed causing an endothermic reaction when mixed is contained separately, and the pack body is also provided with an absorber in a sheet form in it. CONSTITUTION:Pack body 1 is divided into two holding sections 3, 3' by a separating section 2 formed by bonding both surfaces of body 1. Each of materials A, B to be mixed causing an endothermic reaction when mixed is held in each of holding sections 3, 3' separately, and inside base of pack body 1 is provided with absorber in a sheet form 4 to yield the intended instantaneous cooling pack. In application, the bond at separating section 2 is released by pulling both faces of pack body 1 appart, and materials A, B are allowed to mix together to cause the mixture to be absorbed by an absorber in a sheet form 4 in such a way that the pack is cooled uniformly. NH4NO3 as a material A to be mixed, and Na2SO4.10H2O, etc. as a material B to be mixed are used pref.

Description

[Detailed description of the invention] The present invention relates to flash cooling bags.

Unless the conventional oak cooling bag is placed horizontally, the contents will move in one direction, especially to a low place, making it impossible to uniformly cool the surface in contact with the bag.

The present invention has been made for the purpose of eliminating the above-mentioned drawbacks of the prior art. Namely, the present invention has been made in order to accommodate separately the mixture materials exhibiting endotherm according to the IM group, so that they are separated from each other and formed. This is a pack-in-pack coolant having a housing part t- and a releasing part 8tl- for releasing the separation of the space NN and performing mixing, and the coolant body has an absorbent material inside the body wall. Instant cooling pack #C is characterized in that it is provided in contact with at least a portion of the cooling pack #C.

Since the present invention has the above-mentioned configuration, the sheet absorbing material is contained within the bag body, so that the dissolved substance is absorbed by the sheet absorbing material and is applied to the surface that requires cooling. If the bag is in contact with the bag, regardless of the movement of the contents, the bag with sheet absorbent material attached will always have a uniform temperature distribution, and its adhesion to surfaces that require cooling such as the body. It has special feature IIk in that it holds well.

In the present invention, substances that absorb heat when mixed are mixtures or liquids (including substances that partially contain solids).
If so, you can use it.

As the material for the bag body, any material that is normally used for packs can be used as long as it is water-impermeable. For example, synthetic 6iil resin film, (preferably polyethylene, polypropylene, polystyrene, cellulose acetate,)
gold, MW, finim, these alone or in combination (
Vine using fuminate film etc.). In addition, fabrics, non-woven fabrics, sponges, -woven fabrics, natural aAl fibers such as Payapugi, synthetic paper, synthetic paper, metal fibers such as copper, etc. are laminated onto the water-impermeable film, either alone or in combination, and then cooled. Depending on the agent, it may be used with an appropriate thickness and the degree of cooling or heating may be adjusted appropriately. Note that it is advantageous to use an aluminum film or a steel film, which has as good thermal conductivity as possible, as the gold II film, since it is possible to achieve more uniform heat distribution.

If the shape of the bag body is sheet-like, the shape is circle, oval,
It can be any shape such as rhombus, triangle, square, polygon, rectangle, etc., and if it is too large or too thick, it will be disadvantageous in terms of cost and use. It should be about the size of a towel and thick enough to be used as a pillow.

In the present invention, the liquid-absorbing material may be any material as long as it absorbs the liquid T'', and examples thereof include paper, natural fibers such as Vap, non-woven fabrics, M-woven fabrics, fabrics, sponges, polymeric absorbents, etc. .

The shadow line of the absorbent material may be sheet-like or bag-like, and the size, thickness, and shape may be determined as appropriate depending on the bag body. By laminating a thermally conductive metal film with the same or thicker thickness as this non-absorbing surface as this non-absorbing surface, the back surface to which the absorbent material is laminated will be more uniform. It is advantageous to be able to transfer heat to. In this case, by increasing the surface area of the metal film V, it is advantageous that the absorbent material only needs to be provided on a portion 1c of the inner wall surface of the bag.

In the present invention, the formation of the interval #lI portion is arbitrary, and may be in the form of a twill. The isolation means is arbitrary as long as it separates the substances to be mixed into 8 pieces of each substance.For example, the parts in the pack body are pasted together using normal means, and the joined parts are reattached to a suitable place. Here is a case in which a tension force causes a shape to be unraveled 1111. Of course, it is advantageous if the isolation part is bag-shaped, since such means are not required.

Next, an example for carrying out the present invention will be explained in detail based on FIG. II8. The mi diagram is a vertical cross-sectional view showing one example of the implementation of the present invention, and FIG. 2 is a vertical cross-sectional view showing another example of the implementation of the present invention.

In FIGS. 1 and 2, (1) is a bag body, and two housing parts (8, 8') are formed by a separating part (22) in which the inside of the bag body (1) is joined, and each housing part ( a,
8') L is a separate 1111#c/11 combined substance (A
,B) are accommodated. A sheet-like absorbent material (4) is shown bonded to the storage area (1 m) on the inner surface of the bag main body. The queen isolation part (2) is the pasted part in Figure 1, or the back main body in Figure 2.
It consists of a back-down thing of a size that can be used internally.
It is possible to take the form of the words as shown in the figure. In this case,
It is advisable to back up whichever of the mixing substances (A, H) requires a smaller amount.

In addition, the one shown in Figure 1 is provided with an isolation part (2) in the width direction of the back body (IJ in the width direction Ic1lI!i).
It may be provided in the longitudinal direction of the bank body (1) instead of in the width direction. In this case, the sheet absorbent material (4) is not cut in the middle as shown in Fig. 1, but can be formed in one piece. ,
This is advantageous because more heat can be transferred to the ladle.

When using, hold the bag body (υ) in your hand and hold the bag body (
Pinch both sides of 11 with your fingers and pull them in both left and right directions to unstick them (in the case of Fig. 181), then apply pressure from the outside of the bag body (1) to the inner pack interlayer + 2J IC with your hands (such as in the case of Figure 181). Then, if the isolation state is itchy (in the case of Figure 2), from Kotoriko, one mixed product award or the other mixed product 'm 'j
j (d), this mixture is absorbed by the sheet absorbent material (4) Ic, and the temperature change distribution on the back surface of the material to which this is laminated is made uniform to obtain extremely effective cooling properties. By laminating the sheet with absorbent material (4), it is possible to improve the tightness to the body.

Next, a test example of the instant cooling bag of the present invention will be shown.

Test Example 4: NH4N01 was used as a mixture for mixing which showed endotherm.
t' 45 f , also haz as mixing substance B
sO4・10)igo w 65 t are each separately isolated and stored in a bag (rectangular size of 3 m 18.2, thickness 611). Material (4) For comparison, there is a sheet without absorbent material ζ4). (Figure 8 (a) to φ) [Reference 11@] The results are shown in Table 1 below. (
A constant method of temperature change distribution: After opening the isolation part 11 and mixing the mixing substances A and B, the pack t is brought into contact with a vertical surface and the temperature is measured at spots (a,...f). Go ahead. (Degree of opening: 0°C [in Sumire]) Table 1 The present invention uses a sheet-absorbing material as shown in Table 1 above to produce very effective cold young fruit (persistent). It turned out that it was possible to get a scoop.
