[0019] Referring to Figures 1-2 A microwave oven exhaust sealing bag according to an embodiment of the present application is described.
[0020] In one embodiment, as Figure 1 shown, a microwave oven exhaust sealing bag includes a bag body 1, the bag body 1 is provided with a containing cavity, the side edge of the bag body 1 is provided with a side sealing edge 2, the two inner sides of the bag body 1 are of the same material, and at least one pressure relief belt 3 is arranged on one of the inner sides; the pressure relief belt 3 and the inner side are of different materials, and at least one end of the pressure relief belt 3 is sealed with the edge of the other inner side to form an exhaust part 4 located on the side sealing edge 2; the sealing strength of the exhaust part 4 is lower than that of the rest of the side sealing edge 2, and when the pressure in the containing cavity reaches a threshold value, the exhaust part 4 is broken to form an exhaust passage.
[0021] The containing cavity is used to place food, and the side edge of the bag body 1 can include the side edges of the top, both sides and the bottom; the two inner sides of the bag body 1 are made of a commonly used material of the microwave oven sealing bag meeting the food safety requirement standard, the pressure relief belt 3 is made of a different material, but also needs to meet the food safety requirement standard, and due to the difference in the material used, the pressure relief belt 3 forms the exhaust part 4 with a lower sealing strength with the inner side of the bag body 1; the threshold value refers to the pressure threshold value that the containing cavity can withstand, and in specific implementation, when the pressure value in the containing cavity exceeds the threshold value, high-pressure steam will break the exhaust part 4 to form an exhaust passage.
[0022] The microwave exhaust sealing bag provided by the above embodiment can form an exhaust portion 4 on the side sealing edge 2 by arranging a pressure relief belt 3 of different materials on the inner side of the bag body 1. Since the sealing strength of the exhaust portion 4 is lower than the sealing strength of the other parts of the side sealing edge 2, when the pressure in the accommodating cavity reaches a threshold value, the exhaust portion 4 is flushed open to form an exhaust channel, and the high-pressure steam is discharged out of the bag from the exhaust channel, thereby achieving safe exhaust and pressure relief; at the same time, when the food is not heated by a microwave, the pressure in the bag is small, and the exhaust portion 4 is in a sealed state, so that the inside of the bag is in a sealed state and does not contact the outside world, taking into account both sealing and safety.
[0023] In this embodiment, a pressure relief strip 3 is transversely disposed on one inner side surface of the bag body 1 near the bag opening. The two ends of the pressure relief strip 3 are sealed to the two sides of the other inner side surface to form two vents 4. The vents 4 are located on the side seal 2, but their sealing strength is lower than that of other parts of the side seal 2.
[0024] During specific implementation, the pressure relief belt 3 is horizontally arranged below the bag opening. After the bag body 1 is heated and expanded until the internal steam breaks through the exhaust part 4, exhaust can be carried out from the exhaust parts 4 on both sides to ensure that the forces on both sides of the bag body 1 are balanced during exhaust. While preventing the bag body from bursting, it can also avoid the situation where the bag body hits the inner wall of the microwave oven due to the recoil force of unilateral exhaust, which is safer.
[0025] In this embodiment, easy-tear openings 6 are provided on both sides of the bag body 1 below the pressure relief belt 3, so as to facilitate tearing open the bag body 1 from below the pressure relief belt 3 and retrieving the food in the bag.
[0026] In another embodiment, Figure 2 As shown, a microwave exhaust sealing bag includes a bag body 1, a accommodating cavity is provided in the bag body 1, and side seals 2 are provided on the sides of the bag body 1. The two inner sides of the bag body 1 are made of the same material. A folded horizontal strip 5 is provided on one side of the bag surface of the bag body 1. The bag surface includes an upper bag surface and a lower bag surface. The bottom end of one side of the horizontal strip 5 is integrally connected to the bottom end of the upper bag surface, and the bottom end of the other side is integrally connected to the top end of the lower bag surface. The side edges and top ends of both sides of the horizontal strip 5 are sealed and connected to form the side seal 2. At least one pressure relief strip 3 is provided on one inner side of the horizontal strip 5. The top end of the pressure relief strip 3 is sealed to the top edge of the other inner side of the horizontal strip 5 to form a vent 4.
[0027] Among them, the number of pressure relief belts 3 can be one or more, and the required number of pressure relief belts 3 can be set according to factors such as the actual size of the bag body 1, the characteristics of the food stored therein, and user needs; in specific implementation, the pressure relief belt 3 can be arranged horizontally, vertically or even obliquely on the horizontal strip portion 5. In order to facilitate production and exhaust, a vertically arranged pressure relief belt 3 can be selected.
[0028] The microwave oven exhaust sealing bag provided by the above embodiment adds the folded horizontal strip part 5 on one side of the bag body 1, and sets the pressure relief belt 3 on the horizontal strip part 5, so that the exhaust can be reduced to interfere with the overall structure of the bag body 1 on the premise of realizing safe pressure relief, even if the exhaust part 4 on the horizontal strip belt 5 is broken, the overall shape of the bag body 1 will not change, and the risk of food leakage can be more effectively avoided; in addition, the horizontal strip part 5 is in a folded relationship with the bag surface, and when the microwave oven exhaust sealing bag is transported and stored, the horizontal strip part 5 can be pressed and attached to the bag surface, so that the occupied space can be effectively saved, and transportation and storage are facilitated.
[0029] In the embodiment, at least one pressure relief belt 3 is vertically arranged on the horizontal strip part 5. The pressure relief belt 3 is arranged vertically, and the exhaust part 4 formed by the pressure relief belt 3 is located on the side sealing edge 2 at the top of the horizontal strip part 5. The pressure relief belt 3 can be arranged on any inner side of the horizontal strip part 5. In specific implementation, the lower side of the horizontal strip part 5 is in communication with the accommodating cavity, and the high-pressure steam generated by the food during microwave heating can break the exhaust part 4 at the top of the horizontal strip part 5 and be discharged to the outside through the exhaust channel.
[0030] In the embodiment, 2-5 pressure relief belts 3 are arranged on the horizontal strip part 5, and the plurality of pressure relief belts 3 are uniformly distributed on the horizontal strip part 5, so as to ensure that the bag body 1 is balanced when exhausted.
[0031] In the embodiment, the two sides of the bag body 1 are provided with the easy-to-tear opening 6 below the horizontal strip part 5, so as to facilitate tearing the bag body 1 from below the pressure relief belt 3 and taking out the food in the bag.
[0032] Other configurations and operations of the microwave oven exhaust sealing bag according to the embodiments of the present application are known to those skilled in the art, and will not be described in detail here.
