Definitions
- Conventional sodium acetate solution hot packing bag essentially contains sodium acetate and an iron plate. In application, the iron plate is pressed to produce a vibration causing the sodium acetate to become crystallization with an appropriate temperature for hot packing function. However, after the packing bag has been used, the product has to be heated with hot water or microwaved to an appropriate temperature to restore to its solution state for next application. If no heating device is available, the hot packing bag cannot provide normal function. This is a major drawback of the conventional art. However, there are products with heat emission elements. The wire of the heat emission element passes through the sealed opening and connects to an external power source. The wire of the power source passed through the sealing of the bag body causes an uneven structure and the mounting by thermal melting operation is difficult.

- This is a division of the co-pending patent application Ser. No. 09/776,841, filed Feb. 6, 2001.
- (a) Field of the Invention
- The present invention relates to an improved structure of a hot packing bag, and in particular, a packing bag which has not packing effect and with temperature control, timing and sealing function and evenly heat conduction function.
- (b) Description of the Prior Art
- Conventional sodium acetate solution hot packing bag essentially contains sodium acetate and an iron plate. In application, the iron plate is pressed to produce a vibration causing the sodium acetate to become crystallization with an appropriate temperature for hot packing function. However, after the packing bag has been used, the product has to be heated with hot water or microwaved to an appropriate temperature to restore to its solution state for next application. If no heating device is available, the hot packing bag cannot provide normal function. This is a major drawback of the conventional art. However, there are products with heat emission elements. The wire of the heat emission element passes through the sealed opening and connects to an external power source. The wire of the power source passed through the sealing of the bag body causes an uneven structure and the mounting by thermal melting operation is difficult. This is because only complete sealing can avoid leakage of the contents from the bag body. In addition, the pulling of the wire may cause the sealing to break and the contents within the bag body may leak. Additionally, there is not temperature control element timer, temperature regulator, etc provided on the heat emission element to effectively control the heat emission element to emit heat at a specific temperature, which the excessive temperature may break the bag body. Accordingly, it is the aim of the present invention to mitigate the above drawbacks.
- Accordingly, It is an object of the present invention to provide an improved structure of a hot packing bag, wherein the hot packing bag contains sodium acetate or non-conductive solution, solid, and the electric heating plate is provided with temperature control element and an externally connected temperature regulator, timer, so as to effectively control heat emission of electric heating plate at a specific temperature so as to avoid excessive temperature to break the bag body.
- Yet another object of the present invention is to provide an improved structure of a hot packing bag, wherein an improved structure of a hot packing including a plurality of the packing bag bodies and an electric heating structure, and the contents of the bag bodies being sodium acetate solution and iron plate, characterized in that the surrounding edges of the hot packing bag bodies are connectedly sealed and a separate lamination layer is formed between a bag body with a second bag body for the mounting of an electric heating plate, a fastening ring for fastening is provided at the wire passage area for the hot packing bag and the electric heating plate so as to completely seal the bag body to avoid leakage and the electric heating plate is provided with a temperature control element, and an external connected temperature regulator and timer so as to effectively control the heat emission of the electric heating plate at a specific temperature so as to avoid excessive temperature to break the bag body.
- A further object of the present invention is to provide an improved structure of a hot packing bag, wherein the electric heating plate has the same shape as the bag body and the heat emission object on the electric heating plate is a loop structure, allowing evenly heat emission at each corners of the bag body.
- Another object of the present invention is to provide an improved structure of a hot packing bag, wherein the surface of the hot packing bag is provided with heat melting points such that the contents in the hot packing bag will not accumulate at a specific area.
- A further object of the present invention is to provide an improved structure of a hot packing bag, wherein the electric heating plate is a cold/hot chip which has one face providing cold surface and one face providing hot surface, such that the hot packing bag can be rapidly restored and has a cold packing effect.
- The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the Claims should be read in conjunction with the accompanying drawings.
