The above-mentioned technical problems of the utility model are solved in such a way that a reusable heating bag is constructed, and the sealed bag is pre-installed with a concentration of 80-90% sodium acetate aqueous solution and stainless steel metal flakes so that the stainless steel metal flakes are twisted through the sealed bag When the solution is crystallized and generates heat, the surface of the stainless steel sheet is provided with a concave-convex die.

In the reusable heating bag provided according to the utility model, a small amount of food coloring is also included in the solution.

In the reusable heating bag provided according to the utility model, the sealed bag is made of PVC material or other flexible materials.

In the reusable heating bag provided by the utility model, the surface of the sealed bag is also covered with a fiber layer which has the function of keeping warm and improves the hand feeling.

In the reusable heat generating bag provided by the utility model, the sealed bag is processed into a plurality of parts separated from each other, and each part includes a thin stainless steel sheet.

In the reusable heat generating bag provided by the present invention, the parts separated from each other of the sealed bag have different colors.

In the reusable heating bag provided according to the utility model, the sealed bag is provided with a lifting and hanging device which is convenient for taking out when boiled.

In the reusable heating bag provided according to the utility model, the sealed bag is one of heart shape, rectangle shape, circle shape, ellipse shape, ring shape, cartoon character shape, animal outline shape and foot shape.

In the reusable heat-generating bag provided by the utility model, the sealed bag is a long strip, and two ends of the long strip are provided with movable connection devices.

In the reusable heating bag according to the present invention, the sealed bag is a three-dimensional structure, including a bottom and an annular enclosure arranged upwards along the bottom.

The implementation of the reusable heating bag provided by the utility model has the following positive effects. Due to the adoption of different colors and shapes, the decorative effect is better. Since the hanging device is provided, the cured heating bag can be conveniently put into The boiling water is completely liquefied in a few minutes and it can be taken out conveniently, which is convenient for the heat recovery operation of the heating bag. Due to the partition structure, a heating bag can be used for many times. The fiber layer on the surface makes the heating bag feel better.

Detailed ways

As shown in Figure 1, in an embodiment of the reusable heating bag of the present utility model, in the plastic sealing bag 1, concentration is pre-installed and is 80-90% sodium acetate aqueous solution 2 and stainless steel sheet 3 so that through the sealing bag The solution crystallizes and heats up when twisting the stainless steel foil, wherein the sealed bag can have different shapes, for example, rectangular, circular, oval, etc. In order to increase the visual effect of the heating bag, a little food coloring can be added to the solution, so that the heating bag has a more pleasing visual effect. The above-mentioned sealed bag can be made of PVC material or other flexible heat-resistant transparent plastics. Wherein, the surface 3 of the stainless steel metal sheet itself may be a concave thin sheet and a plurality of horizontal and vertical concave-convex dies 4 are arranged on the sheet surface.

In the second embodiment shown in Fig. 2, the sealed bag is processed into the shape of a foot, which can be used as an insole that generates heat, and is used in cold regions in winter. A layer 5 of fibers such as cotton yarn or other is applied.

In the third embodiment shown in Fig. 3, the plastic sealed bag is processed into five small bags 6 separated from each other, and each small bag 6 contains a stainless steel thin metal sheet 3, so that it can be used in batches, in order to increase the visual effect of use , can be sealed in individual sachets with solutions of different colors. In order to solve the problem that the pouch is not easy to take out from entering the hot water, a lifting device 7 that is convenient to take out when boiled is also provided on one side or around the sealed bag.

Figure 4 shows that the sealed bag is processed into a form with flexible connection devices at both ends, so that when the heat is generated, it can be wrapped around the position that needs to be heated and kept warm, for example, the abdomen. The strip-shaped sealed bag can have multiple independent segments, Thus using one by one, greatly prolonging the heating time. The movable connection device can be a hasp, a snap button, a nylon sticker, etc., and can have different lengths and widths according to the position of use.

In Fig. 5 embodiment, the structure of the sealed bag of three-dimensional structure is provided, and this sealed bag has a circular bottom 9, and annular guard 10 is arranged along the circular bottom 9, and the sealed bag of this structure can be used as beverage can heating or bottle warmed. If there are separate cells inside, they can also be used one by one to extend the heating and heat preservation time.
