[0002] With the popularity of microwave ovens, microwave foods that can be eaten after being heated in the microwave have also emerged. Microwave foods are usually placed in sealed packaging bags for easy transportation. When the food packaging bag is sealed, a low-strength opening needs to be reserved. When the internal gas is heated and pressurized, the low-strength opening will become the first explosion opening, so as to open the microwave bag and release the internal pressure to avoid bursting.

[0003] At present, the existing food packaging bags usually include a packaging bag body composed of two main bag surfaces that are sealed and connected to each other on all sides, a sealed space is formed inside the packaging bag body, and sealing strips are formed on all sides of the packaging bag body. A pressure relief hole is provided on the food packaging bag. When the food contains a lot of juice, the juice is easy to spray out from the pressure relief hole after heating. Since the exhaust pressure of the pressure relief hole is relatively large, the juice is easy to spray on the inner wall of the microwave oven after spraying out from the pressure relief hole, which not only affects people's experience of heating food, but also requires people to clean the juice attached to the inner wall of the microwave oven. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a high-temperature bag that can be heated in a microwave, which can solve the problem that due to the high exhaust pressure of the pressure relief hole, juice is easily sprayed on the inner wall of the microwave oven after being sprayed out of the pressure relief hole, which not only affects people's experience of heating food, but also requires people to clean the juice attached to the inner wall of the microwave oven.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature bag that can be heated in a microwave, comprising a food packaging bag, a surface of the food packaging bag is provided with an easy-tear strip, the surface of the easy-tear strip is fixedly connected to a pull ring, a top of the food packaging bag is provided with a liquid storage groove, the inside of the liquid storage groove is adhered with a sealing strip, the top of the food packaging bag is fixedly connected to a pressure relief pipe, the top of the food packaging bag is fixedly connected to a spiral exhaust pipe, the spiral exhaust pipe is connected to the pressure relief pipe, a conical sealing plug is fixedly connected to the surface of the sealing strip, and the conical sealing plug is slidably clamped in the exhaust port of the spiral exhaust pipe.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] See also Figure 1-4 The utility model provides a technical solution: a high-temperature bag that can be heated in a microwave, comprising a food packaging bag 1, a surface of the food packaging bag 1 is provided with an easy-tear strip 2, the surface of the easy-tear strip 2 is fixedly connected with a pull ring 11, people can tear off the easy-tear strip 2 more conveniently through the pull ring 11, and it is convenient for people to take food inside the food packaging bag 1, a pressure relief pipe 4 is fixedly connected to the top of the food packaging bag 1, a block 6 is fixedly connected to the inside of the pressure relief pipe 4, a pressure relief port 7 is opened on the surface of the block 6, a cross-shaped block 8 is fixedly connected to the inside of the pressure relief pipe 4, a spring 9 is fixedly connected to the surface of the cross-shaped block 8, and a truncated cone sealing block 10 is fixedly connected to the end of the spring 9 away from the cross-shaped block 8, and the truncated cone sealing block 10 is slidably clamped inside the pressure relief port 7.

[0025] When the pressure inside the food packaging bag 1 increases, the gas inside the food packaging bag 1 squeezes the conical sealing block 10 and causes the conical sealing block 10 to slide and squeeze the spring 9. At this time, the spring 9 gives the conical sealing block 10 a reverse force. After the conical sealing block 10 slides out of the pressure relief port 7, the gas inside the food packaging bag 1 is discharged from the pressure relief port 7 to complete the pressure relief. When the gas inside the food packaging bag 1 is discharged and the pressure inside is reduced, the spring 9 can release the elastic force and push the conical sealing block 10 to slide into the pressure relief port 7, and then the pressure relief port 7 is automatically sealed by the conical sealing block 10. The spring 9 pushes the conical sealing block 10 to slide inside the pressure relief port 7, which can automatically exhaust and relieve the pressure of the food packaging bag 1, so that the food packaging bag 1 can achieve the purpose of automatic pressure relief, avoid the food packaging bag 1 from bursting, and ensure the safety of people heating the food packaging bag 1.

[0026] A spiral exhaust pipe 5 is fixedly connected to the top of the food packaging bag 1, and the spiral exhaust pipe 5 is connected to the pressure relief pipe 4. A liquid storage groove 3 is provided on the top of the food packaging bag 1, and a sealing strip 12 is adhered to the inside of the liquid storage groove 3. The inside of the liquid storage groove 3 is sealed by the sealing strip 12 to prevent dust and other impurities from entering the inside of the liquid storage groove 3, thereby ensuring the cleanliness of the inside of the liquid storage groove 3. When the food needs to be heated, it is only necessary to tear off the sealing strip 12. A conical sealing plug 13 is fixedly connected to the surface of the sealing strip 12, and the conical sealing plug 13 is slidably engaged with the exhaust port of the spiral exhaust pipe 5.

[0027] The gas discharged from the food packaging bag 1 first passes through the pressure relief pipe 4, and then enters the interior of the spiral exhaust pipe 5 through the pressure relief pipe 4. The gas moves in a circular shape for multiple circles inside the spiral exhaust pipe 5 and then is discharged to the outside. The gas is discharged after moving a long path to reduce its power, preventing the gas from splashing with the juice of the food. In the process of the gas driving the juice to move inside the spiral exhaust pipe 5, the juice contained in the gas gradually flows to the bottom of the spiral exhaust pipe 5 due to its own gravity and flows out to the inside of the liquid storage groove 3. The discharged juice is collected by the liquid storage groove 3 to prevent the juice from flowing to the inner wall of the microwave oven, which not only improves people's experience of heating food, but also eliminates the need for people to clean the juice attached to the inner wall of the microwave oven.

[0028] Working principle: In the high-temperature bag that can be heated in a microwave, the gas inside the food packaging bag 1 squeezes the conical sealing block 10, and causes the conical sealing block 10 to slide and squeeze the spring 9. After the conical sealing block 10 slides out of the pressure relief port 7, the gas inside the food packaging bag 1 is discharged from the pressure relief port 7 to complete the pressure relief. The spring 9 can release the elastic force and push the conical sealing block 10 to slide into the pressure relief port 7, and then the pressure relief port 7 is automatically sealed by the conical sealing block 10. The gas moves in a circular shape for multiple circles inside the spiral exhaust pipe 5 and then is discharged to the outside. The gas is discharged after moving a long path to reduce its power, preventing the gas from splashing with the juice of the food. The juice contained in the gas gradually flows to the bottom of the spiral exhaust pipe 5 through its own gravity and flows out to the inside of the liquid storage groove 3. The discharged juice is collected by the liquid storage groove 3 to prevent the juice from flowing to the inner wall of the microwave oven.

[0029] The materials of the structures involved in this plan are all PP-polypropylene. PP-polypropylene is a plastic that can be put into a microwave oven. It is a very common material for microwave lunch boxes. It is very resistant to high temperatures and can withstand up to 110 degrees.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
