[Industrial applications]

 The present invention relates to a heat pack having a kind of recycle structure, and the present invention is that the supercooled sodium acetate solution in the heat pack is crystallized by the activation reaction and radiates heat, and then the power is supplied to generate heat in the recycle structure. The present invention relates to a heat pack having a reusable structure, which reacts with sodium acetate crystals to reduce the temperature to a room temperature and serves the purpose of repeated recycling.

[Prior art]

 Heat packs are used for physical treatment, such as stiffness in the lower back and shoulders, recovery of health and movement disorders of sportsmen, and also for heat retention of the body. Since the early heat packs used water as the heating material, it was difficult and troublesome to control the water temperature, and it was not suitable for outdoor use.

Next, a heat pack in which an aqueous solution of a kind of salt was placed in a closed container and precooled appeared. This uses an activator at the time of use and causes crystallization by the activation reaction of an aqueous solution of a supercooled salt, and at the same time releases heat, and this container has the effect of a heat pack. It was However, when it is desired to use the heat pack again, a certain amount of heat must be given to the salt water crystals to reduce the salt water crystals to form a supercooled salt aqueous solution at room temperature.In use, the heat pack is wrapped with a cloth. The so-called boiled reduction method was used in which a salt water crystal was placed in a pan and water was added to form a completely transparent and amorphous aqueous solution. This reduction method takes about 6 to 20 minutes, and if you inadvertently leave the heat pack boiled, there is a risk of explosion, and the boiled reduction method has water and a heat source. It was the first time that it could be done, and the reduction process was troublesome, and when it was used outdoors, it could not be reduced and reused.

Another type of heat pack reduction method is a method of heating using an electromagnetic pot. This can save the troublesome heating process of the boiling reduction method, but the heating by the electromagnetic cup was dangerous because it caused the heat pack to burst when the temperature control was not appropriate.

[0007]

[Action]

 According to the present invention, a dish-shaped activation starter and a reusable structure are provided in a flexible bag that contains a supercooled sodium acetate solution and has flexibility. By bending and activating the supercooled sodium acetate solution to form sodium acetate crystals, and releasing heat at the same time as the reaction, the bag has the effect of a heat pack, and the heat pack returns to room temperature. After that, power is supplied to apply reductive heat energy to the reusable structure, which causes the sodium acetate crystals to react and reduce, resulting in a supercooled sodium acetate solution under normal temperature conditions. Make a cyclical use.

【Example】

 Shown in FIGS. 1 and 2 is the heat pack of the present invention. As shown in these figures, the present invention has one flexible bag (1), a sodium acetate solution (2) mixed at a required temperature, and an activity of a supercooled sodium acetate solution. It consists of a dish-shaped activation starter (3) that causes chemical reaction, and one recycle structure (4) that reduces sodium acetate crystals.

The closed bag (1) is not affected by the sodium acetate solution (2) and the sodium acetate solution (2) does not permeate, and the closed bag (1) has a high temperature (60 ° C.). It shall withstand high temperatures (~ 65 ° C) and be transparent so that the user can easily see the position of the activation starter (3).

When manufacturing the closed bag body (1), a sodium acetate solution (2), an activation starter (3) and a dish type activation starter (3) are put in advance leaving one opening. To serve. And change the size and shape according to the application.

Sodium acetate is soluble in a suitable amount of water. For example, a sodium acetate solution prepared by dissolving 100 g of sodium acetate in 100 g of water has a temperature of 38 ° C. generated by the activation reaction, and the generation temperature is 54 ° C. when the proportion of water is 75 g. If the proportion of water is 50 g, the generation temperature will be 57 ° C. If necessary, adjust the proportion of sodium acetate and water to obtain a temperature within the operating range of the heat pack.

As shown in FIG. 2, the dish-shaped activation starter (3) in the closed bag body (1) is made of a flexible metal, and the activation starter (3) is bent. Along with this, an elongated activator cut (31) is provided on the activation starter (3) by pressing, and when the activation starter (3) is bent, the sodium acetate solution causes an activation reaction.

A feature of the present invention resides in the reusable structure (4) in the closed bag body (1), which has at least one heating wire (41) and plug (42). Among them, the heating wire (41) is made of one flexible conductive material, and the temperature within the control is obtained by the material and the length thereof. In addition, the plug (42) can be connected by being connected to a general vehicle power source, and can also be used as a household power source by adding a transformer.

In the production of the heat pack of the present invention, first, the sodium acetate solution (2), the activation starter (3), and the reusable structure (4) are placed in a container and sealed, and the sealed bag is heated. Then, the sodium acetate solution (2) therein is completely dissolved, and then the sodium acetate solution (2) is supercooled to complete.

When using the heat pack of the present invention, simply fold the activation starter (3) and the sodium acetate solution (2) crystallizes due to the activation reaction and at the same time releases heat. After the crystallization of the sodium acetate solution (2) is completed, the power source is passed through the recycling structure (4), and the heat radiation reduces the sodium acetate crystals to form the sodium acetate solution (2) at room temperature. So heat packs can be used repeatedly.
