Description

Technical Field

[0001] The utility model relates to the technical field of soft packaging, and more particularly to a microwave sealing bag. Background Art

[0002] Microwave heating, as a convenient and fast way to heat food, has been widely used in households and the catering industry in recent years. In daily life, for convenience, people often use plastic sealed bags as food packaging to heat food directly in a microwave oven.

[0003] However, the sealing structure of traditional microwave-sealed bags generally includes sealing strips symmetrically arranged on both sides of the bag opening. During microwave heating, the heat and steam released by the food after absorbing the microwaves will increase the pressure inside the bag, causing the bag to expand. The sealing strip at the bag opening becomes the force center and is subjected to forces in opposite directions, causing the bag to easily burst at the position of the sealing strip. In addition, traditional microwave-sealed bags do not have exhaust vents. During microwave heating, the high-pressure steam in the bag may cause the bag to burst, resulting in poor safety. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides a microwave sealing bag, which can prevent the bag body from bursting and has good safety.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a microwave oven sealing bag, comprising a bag body, a accommodating cavity is provided in the bag body, side sealing edges are provided at the bottom and both sides of the bag body, and a sealing structure is provided at the bag opening at the top of the bag body; the sealing structure comprises a first sealing part and a second sealing part that cooperate with each other; the first sealing part is provided at the middle part of a first mounting piece, and the top and bottom of the first mounting piece are both sealed to the inner side of one side of the bag body; the second sealing part is provided at the bottom of the second mounting piece, and only the top of the second mounting piece is sealed to the inner side of the other side of the bag body; exhaust parts are respectively provided on the side sealing edges on both sides.

[0006] In a preferred technical solution, the exhaust portion includes a patch attached between the inner surfaces of the two sides of the side seal; the patch is made of a different material from the bag body, so that the edge sealing strength of the exhaust portion is lower than the edge sealing strength of the rest of the side seal. When the pressure in the accommodating cavity reaches a threshold, the exhaust portion is flushed open to form an exhaust channel.

[0007] In a preferred technical solution, one side of the patch is completely attached to the inner surface of one side seal, and the other side of the patch is partially attached to the inner surface of the other side seal; the minimum width of the partial attachment area between the patch and the side seal is less than the width of the side seal.

[0008] In a preferred technical solution, the partial bonding area between the patch and the side seal is located at the outer edge of the side seal.

[0009] In a preferred technical solution, the exhaust part is arranged on the side sealing edge below the sealing structure.

[0010] In a preferred technical solution, the top of the second mounting sheet is aligned with the top of the first mounting sheet, and the width of the second mounting sheet is equal to half of the width of the first mounting sheet.

[0011] In a preferred technical solution, the first sealing part and the second sealing part comprise at least two pairs of sealing strips.

[0012] In a preferred technical solution, the first sealing part comprises a first convex rib and a second concave part, and the second sealing part comprises a first concave part and a second convex rib; the first convex rib is sealed with the first concave part, and the second convex rib is sealed with the second concave part.

[0013] Via the above technical solution, compared with the prior art, the microwave oven sealing bag has the beneficial effects that: the first sealing part is mounted on one side of the bag body through the first mounting sheet, and the second sealing part is connected with the other side of the bag body through the second mounting sheet, so that the sealing structure is located on one side of the bag body in the sealing state, and thus the stress point is at the top of the second mounting sheet and the bag body sealing joint when the bag body expands, instead of at the sealing structure, thereby effectively preventing the sealing structure from exploding when heated by the microwave; meanwhile, the exhaust part is arranged on the side sealing edge on both sides, and the exhaust can be performed from both sides at the same time, which can not only prevent the bag body from exploding, but also avoid the situation that the bag body hits the inner wall of the microwave oven due to the back pressure of one-side exhaust, and the safety is better.

[0022] Reference Figs. 1-3 A microwave oven sealing bag according to an embodiment of the present application is described.

[0023] In one embodiment, as shown in Figs. 1-3 A microwave oven sealing bag, comprising a bag body 1, the bag body 1 is provided with a receiving cavity, the bottom and both sides of the bag body 1 are provided with side sealing edges 2, and the bag opening at the top of the bag body 1 is provided with a sealing structure 3;

[0024] The sealing structure 3 comprises a first sealing part 31 and a second sealing part 32 which cooperate with each other; the first sealing part 31 is arranged at the middle part of a first mounting piece 41, and the top and bottom of the first mounting piece 41 are sealed on the inner side of one face of the bag body 1; the second sealing part 32 is arranged at the bottom of a second mounting piece 42, and only the top of the second mounting piece 42 is sealed on the inner side of the other face of the bag body 1;

[0025] The side sealing edges 2 on both sides are respectively provided with exhaust parts 5.

[0026] The first mounting piece 41 and the second mounting piece 42 can be of the same material as the bag body 1, and have greater sealing strength. The first sealing part 31 and the second sealing part 32 are opposite to each other and are matched with each other. Further, the two exhaust parts 5 are also opposite to each other. In a specific implementation, the sealing structure 3 formed by the first sealing part 31 and the second sealing part 32 is located on one side of the bag body 1 in a sealing state, and is not located in the middle. Therefore, when the bag body 1 is inflated by high-pressure steam generated by heating food, the stress position is not on the sealing structure 3, but on the top of the second mounting piece 42 and the sealing position of the bag body 1, so that the sealing structure 3 is not easily pulled open. In addition, the bag body 1 is provided with the exhaust part 5 on both sides, so that the two sides can be exhausted at the same time, and the bag body 1 is uniformly stressed during the exhaust process, so that the bag body 1 will not collide with the microwave oven in the microwave oven, and the safety during heating is ensured.

[0027] The microwave oven sealing bag provided by the above embodiment is characterized in that the first sealing part 31 is mounted on one side of the bag body 1 through the first mounting piece 41, and the second sealing part 32 is connected to the other side of the bag body 1 through the second mounting piece 42, so that the sealing structure 3 is located on one side of the bag body 1 in a sealing state. In this way, when the bag body 1 is inflated, the stress point is on the top of the second mounting piece 42 and the sealing position of the bag body 1, rather than on the sealing structure 3, so that the sealing structure 3 can be effectively prevented from being blown open during microwave heating. At the same time, the side sealing edges 2 on both sides are provided with the exhaust part 5, so that the two sides can be exhausted at the same time, which can not only prevent the bag body 2 from being blown open, but also avoid the situation that the bag body 2 collides with the inner wall of the microwave oven due to the back pressure of one-side exhaust, and the safety is better.

[0028] In the embodiment, the exhaust part 5 includes a patch 6 attached between the inner surfaces of the two side sealing edges 2. The patch 6 is different in material from the bag body 1, so that the sealing strength of the exhaust part 5 is lower than that of the other parts of the side sealing edge 2. When the pressure in the accommodating cavity reaches a threshold value, the exhaust part 5 is blown open to form an exhaust passage. The exhaust part 5 is realized by the patch 6 which is different in material from the bag body 1. Because the materials are different, the sealing strength of the exhaust part 5 is lower, and the exhaust part 5 is more easily blown open to form an exhaust passage. When the exhaust part 5 is not blown open, the accommodating cavity is in a sealed state, so that the food inside can be kept in a sealed state.

[0029] In the embodiment, one side of the patch 6 is completely attached to one inner surface of the side sealing edge 2, and the other side of the patch 6 is partially attached to the other inner surface of the side sealing edge 2. The minimum width of the partially attached area of the patch 6 and the side sealing edge 2 is smaller than the width of the side sealing edge 2. The partially attached area of the patch 6 and the side sealing edge 2 constitutes a sealing edge area of the exhaust part 5. On the basis that the sealing strength of the exhaust part 5 is lower than that of the side sealing edge 2, the attached area is also smaller, so that the sealing edge of the exhaust part 5 is more easily blown open by high-pressure steam to form an exhaust passage, so that the exhaust part 5 can automatically exhaust during high-temperature inflation, and has the effect of high-temperature explosion prevention.

[0030] In the embodiment, the part of the patch 6 and the side sealing edge 2 are located at the outer edge of the side sealing edge 2, that is, the part of the patch 6 not adhered to the side sealing edge 2 is located in the accommodating cavity, which ensures the sealing property and facilitates production.

[0031] In the embodiment, the exhaust part 5 is arranged on the side sealing edge 2 below the sealing structure 3, when the microwave oven sealing bag is placed in the microwave oven for heating in the sealed state, the high-temperature steam generated by the internal food makes the bag body 1 swell, since the stress point is not on the sealing structure 3 but at the sealing position of the second mounting piece 42 and the bag body 1, the sealing structure 3 will not be broken and opened, when the internal pressure of the bag body 1 reaches a certain threshold value, the exhaust part 5 on the side sealing edge 2 below the sealing structure 3 can be broken to form an exhaust passage to exhaust, thereby avoiding the bag body 1 from being burst.

[0032] In the embodiment, the top of the second mounting piece 42 is aligned with the top of the first mounting piece 41, and the width of the second mounting piece 42 is equal to half of the width of the first mounting piece 41, which facilitates the alignment and adhesion of the first sealing part 31 and the second sealing part 32 and ensures the sealing property.

[0033] In the embodiment, the first sealing part 31 and the second sealing part 32 comprise at least two pairs of sealing strips to ensure the sealing property of the bag body 1.

[0034] Further, the first sealing part 31 comprises a first convex rib 311 and a second concave part 312, the second sealing part 32 comprises a first concave part 321 and a second convex rib 322, the first convex rib 311 is matched and sealed with the first concave part 321, and the second convex rib 322 is matched and sealed with the second concave part 312, in the above embodiment, the first convex rib 311 and the first concave part 321 and the second convex rib 322 and the second concave part 312 are matched and sealed to form double sealing, which has better sealing effect.

[0035] The other constitution and operation of the microwave oven sealing bag according to the embodiment of the utility model are known to those skilled in the art, which will not be described in detail here.
