This bag is usually made of high temperature resistant materials, such as polyester, polypropylene, nylon and other polymer materials, to ensure that it is not easy to melt or deform during microwave heating. High temperature bag has excellent sealing performance, which can effectively prevent food contamination and external bacteria invasion during heating, and ensure food hygiene and safety.

[0003] Existing high-temperature bags are usually sealed using heat sealing technology, that is, using high temperature and pressure to melt the bag materials and tightly combine them together to form a sealed seal. However, after opening the high-temperature bag, it is difficult to close the seal, which is inconvenient to carry outside. At the same time, it may take more time and effort to open the seal, thereby reducing the practicality of the packaging bag. 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 heat-resistant high-temperature bag for microwave heating, which can solve the problem that it is difficult to close the seal of the high-temperature bag after opening it, which is inconvenient to carry outside and may require more time and effort to open the seal, thereby reducing the practicality of the packaging bag.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat-resistant high-temperature bag for microwave heating, comprising a protective layer, on which a limiting device is arranged;

[0030] Compared with the prior art, the beneficial effects of the utility model are:

[0031] (1) The heat-resistant high-temperature bag for microwave heating is characterized in that the limit block in the limit device is pushed downward to drive the return spring to contract while the protective cover is twisted to rotate. Then, the protective cover can be rotated without the limit block to drive the fixed block to rotate so that the fixed block is aligned with the opening of the fixed block groove. Then, the protective cover can be pulled to separate the protective cover from the feeding tube. This makes it easy to remove the protective cover to open the seal of the packaging bag, avoiding the inability to close the seal after opening, and effectively improving the practicality of the equipment.

[0032] (2) The heat-resistant high-temperature bag for microwave heating is formed by converting the moisture in the raw material of the packaging bag into steam, which causes the internal pressure of the packaging bag to gradually increase, and the force generated causes the diaphragm to open, so that the steam is filtered through the filter plate and discharged. Once the pressure is reduced, the diaphragm will close again to maintain the sealing of the packaging bag, thereby preventing the packaging bag from cracking due to excessive pressure, effectively protecting the packaging bag, and at the same time increasing the service life of the packaging bag.

[0042] See also Figure 1-3 , the utility model provides a technical solution: a heat-resistant high-temperature bag for microwave heating, comprising a protective layer 1;

[0043] A limiting device is provided on the protective layer 1;

[0044] The limiting device includes a feed pipe 8, a protective cover 7 and a fixed block 6. A fixed block groove 3 is provided on the outer wall of the feed pipe 8. The protective cover 7 is slidably connected inside the feed pipe 8. The fixed block 6 is fixedly connected to the outer wall of the lower end of the protective cover 7. The fixed block groove 3 is "L"-shaped. The outer wall of the fixed block 6 is slidably connected to the inside of the fixed block groove 3. A limiting block groove 2 is provided inside the fixed block groove 3. The limiting block 9 is slidably connected inside the limiting block groove 2. The outer wall of the limiting block 9 contacts the outer wall of the fixed block 6. Two return springs 10 are provided inside the limiting block groove 2. The two ends of the two return springs 10 are respectively fixedly connected to the inner wall of the corresponding limiting block groove 2 and the outer wall of one end of the limiting block 9.

[0045] Among them, the interior of the protective layer 1 is bonded and connected to the middle layer 11, the interior of the middle layer 11 is bonded and connected to the inner layer 12, the feed pipe 8 is fixedly connected to the upper surface of the protective layer 1, the upper surface of the protective layer 1 is fixedly connected to the air outlet pipe 14, the outer wall of the air outlet pipe 14 is rotatably connected to the protective sleeve 4, the interior of the feed pipe 8 is communicated with the interior of the inner layer 12, the interior of the air outlet pipe 14 is communicated with the interior of the inner layer 12, the end of the protective sleeve 4 away from the protective layer 1 is fixedly connected to the filter plate 5, the interior of the air outlet pipe 14 is installed with a diaphragm 13, the interior of the protective sleeve 4 is communicated with the interior of the air outlet pipe 14, the protective layer 1 is composed of polyester film material, the middle layer 11 is composed of aluminum foil material, and the inner layer 12 is composed of polypropylene film material.

[0046] Furthermore, when using the device, first push the limit block 9 downward to drive the return spring 10 to contract while twisting the protective cover 7 to rotate. Then, the protective cover 7 can be rotated without the limit of the limit block 9 to drive the fixed block 6 to rotate so that the fixed block 6 is aligned with the opening of the fixed block groove 3. Then, the protective cover 7 can be pulled to separate the protective cover 7 from the feed pipe 8, and then the raw material can be put into the inner layer 12 through the feed pipe 8.

[0047] Furthermore, when the packaging bag is placed in a microwave oven for heating, the packaging bag is placed inside the microwave oven for heating, and then the inner layer 12 is protected from the external environment by the protective layer 1 while the packaging bag is heated. Then, the moisture in the raw material of the packaging bag is converted into steam, causing the internal pressure of the packaging bag to gradually increase and the force generated causes the diaphragm 13 to open, allowing the steam to be filtered through the filter plate 5 and then discharged. Once the pressure is reduced, the diaphragm 13 will close again to maintain the sealing of the packaging bag. The materials used in this solution are all polypropylene resins, which are materials that can be used for microwave heating.

[0048] The limit block 9 is pushed downward in the limit device to drive the return spring 10 to contract while the protective cover 7 is twisted to rotate. Then, the protective cover 7 can be rotated without the limit of the limit block 9 to drive the fixed block 6 to rotate so that the fixed block 6 is aligned with the opening of the fixed block groove 3, and then the protective cover 7 can be pulled to separate the protective cover 7 from the feeding pipe 8. This makes it easy to disassemble the protective cover 7 to open the seal of the packaging bag, avoiding the inability to close the seal after opening, and effectively improving the practicality of the equipment. The moisture in the raw material of the packaging bag is converted into steam, resulting in the gradual increase in the internal pressure of the packaging bag. The force generated causes the diaphragm 13 to open, so that the steam is filtered through the filter plate 5 and discharged. Once the pressure is reduced, the diaphragm 13 will be closed again to maintain the sealing of the packaging bag, thus avoiding the packaging bag from cracking due to excessive pressure, effectively protecting the packaging bag, and at the same time increasing the service life of the packaging bag.

[0049] Working principle: first, push the limit block 9 downward to drive the return spring 10 to contract while twisting the protective cover 7 to rotate, then the protective cover 7 can be rotated without the limit of the limit block 9 to drive the fixed block 6 to rotate so that the fixed block 6 is aligned with the opening of the fixed block groove 3, and then pull the protective cover 7 to separate the protective cover 7 from the feeding pipe 8, and then put the raw materials into the inner layer 12 through the feeding pipe 8, and then put the packaging bag into the microwave oven for heating. When heating, the packaging bag is placed in the interior of the microwave oven for heating, and then while the packaging bag is heated, the protective layer 1 is used to protect the inner layer 12 from the influence of the external environment, and then the moisture in the raw materials of the packaging bag will be converted into steam, resulting in the gradual increase in the internal pressure of the packaging bag. The force generated causes the diaphragm 13 to open, so that the steam is filtered through the filter plate 5 and discharged, and once the pressure is reduced, the diaphragm 13 will close again to maintain the sealing of the packaging bag. The materials used in this scheme are all polypropylene resins, which are materials that can be used for microwave heating.
