Embodiment 1

[0020] Example 1, as shown in Figures 1 and 2, a self-heating warm bag includes an outer bag 1 and an inner bag 3, the inner bag 3 is sealed inside the outer bag 1, the outer bag 1 is made of PE material, and the inner bag 3 is made of It is made of cast film with air-permeable micropores 2 on the surface, and three layers of sheet-shaped self-heating agent 4 are packaged in the inner bag 3 through heat-sealing and sealing. The sheet-shaped self-heating agent 4 is made of the following raw materials: 75g of iron powder, activated carbon 15g, salt 4g, cotton fiber 15g, gelatin 5g, water 20g.

Embodiment 2

[0021] Embodiment 2, as shown in Figures 3 and 4, a self-heating warm bag, including an outer bag 1 and an inner bag 3, the outer bag 1 is made of PP material, and the inner bag 3 is made of a composite material with air-permeable micropores 2 on the surface. The inner bag 3 is sealed inside the outer bag 1, and the inner bag 3 is sealed with six layers of sheet-shaped self-heating agent 4 through heat-sealing. The inner bag 3 has a drug layer 6 attached to the outer surface, and the drug layer 6 is for external use. Plaster, medicament layer 6 is provided with viscose layer 5 attached to inner bag 3 sides around, and plaster 6, viscose layer 5 are provided with protective film 7 outside, and protective film 7 is pulled off during use, and plaster 6 is aimed at body For the treatment part, the adhesive layer 5 can be stuck on the skin, and the curative effect of the medicine can be improved by heating with a warm bag. The sheet-shaped self-heating agent 4 is made of the follow...

Embodiment 3

[0022] Example 3, as shown in Figure 5, a self-heating warm bag, including an outer bag 1 and an inner bag 3, the outer bag 1 is made of aluminum-plastic composite film, the inner bag 3 is sealed inside the outer bag 1, and the inner bag 3 is used Made of non-woven fabric with micropores 2, a self-adhesive layer 5 is attached and fixed on one side, and a layer of sheet-shaped self-heating agent 4 is packaged in the inner bag 3, wherein the sheet-shaped self-heating agent 4 is made of the following raw materials Ingredients: Iron powder 60g, activated carbon 5g, salt 5g, hemp fiber 20g, gelatin 3g, water 25g. According to the needs of actual calorific value and the size of the warm bag, 4-6 layers or even more layers of self-heating agent 4 in sheet form can be placed, and the self-adhesive layer 5 is uncovered and pasted on the corresponding parts of the body during use.

Abstract

The invention discloses a thermal bag self-heating, which comprises an airtight external bag, an internal bag. The internal bag is sealed in the external bag, which is provided with micro breather holes on surface and is internally sealed with at least one layer of slice-shaped self-heating agent; the self-heating agent is made of the following ingredients: ferrous powder, active carbon, salt, plant fibre, glutin and water. The invention resolves the problems as ash leakage, dropping and unevenness existed in the prior art, which has the advantages of flatness, good handle, long time for heating, reliable and gentle temperature, low requirements on package and simple fabrication.

Description

technical field [0001] The invention relates to a warm bag. Background technique [0002] In recent years, many kinds of convenient self-heating warm bags have emerged, generally in the form of acetic acid reusable self-heating warm bags that trigger crystallization and heat release through chips, and disposable self-heating warm bags with iron powder as the main agent. . The raw material of the warm bag with iron powder as the main agent is mainly iron powder, which generates heat by using the exothermic heat generated by the oxidation reaction of iron. According to the Chinese patent of the above-mentioned disposable self-heating warm bag, the raw materials of the above-mentioned disposable self-heating warm bag are all powder or granular, but because the oxidation reaction needs oxygen in the air, there must be vent holes on the inner bag to allow oxygen to react with iron powder, and there are generally many vent holes Acupuncture holes are adopted, and the self-heatin...
