[0002] A cooking bag is a special packaging material that has the ability to maintain the nutrition, flavor, and safety of food at high temperatures. Such bags are usually used in the food packaging field, especially for foods that need to undergo cooking or heating processes, such as cooked foods, meats, seafood, soy products, etc.

[0003] Existing cooking bags generally seal the opening of the cooking bag through a hot-pressing fixation method and open the cooking bag by opening a tear notch on the side of the cooking bag. The cooking bag cannot be reused for sealing, and when using the cooking bag, if there is moisture inside the cooking bag, during the heating process of the cooking bag, there is often still relatively hot water vapor inside. At this time, if the operator directly tears the cooking bag, it will cause the operator's hand to come into contact with the high-temperature water vapor inside the cooking bag, resulting in damage to the operator's hand. Content of the Utility Model

[0004] The purpose of the utility model is to provide a straight-line easy-to-tear cooking bag to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A straight-line easy-to-tear cooking bag, including a cooking bag body, a sealing mechanism is provided at the top of the cooking bag body. The sealing mechanism includes a buckle. The top of the cooking bag body is inserted into the buckle and is in interference fit with the inner wall of the buckle. Two rubber rods are oppositely arranged inside the opening of the cooking bag body, and the two opening walls on the front and back sides of the cooking bag body are both curved and are respectively fixedly connected to the outer peripheral walls of the two rubber rods.

[0006] An exhaust hole with a cross-sectional shape of a T-shape is opened at the middle position on the top side of the buckle, and a plugging mechanism is provided in the exhaust hole.

[0007] Preferably, a plugging film is provided on the left side of the buckle, and the plugging film is fixedly connected to the buckle through an adhesive, and the plugging film is in contact with the cooking bag body.

[0008] Preferably, the opening edges at the left end of the buckle and the opening edges at the bottom side of the buckle are both arc-shaped, and the right side of the buckle is a solid shape.

[0009] Preferably, the plugging mechanism includes a limiting strip which is slidably installed in the exhaust hole. An elastic plate is fixedly installed on the top side of the limiting strip, and the bottom side of the elastic plate is in contact with the top side of the limiting strip. The top view area of the elastic plate is larger than that of the exhaust hole. A plurality of elastic blocks are relatively fixedly installed on the bottom side of the limiting strip, and the bottom end of each elastic block is fixedly connected to the inner wall of the exhaust hole through an adhesive.

[0010] Preferably, a plurality of air guide grooves are formed on the front and rear inner walls of the exhaust hole, and the distance between adjacent two air guide grooves is equal. The air guide grooves are located below the elastic plate.

[0011] Preferably, a sealing ring is fixedly installed in the elastic plate, and the bottom side of the sealing ring extends to the bottom side of the elastic plate and is in interference fit with the top side of the buckle.

[0024] In order to make the technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] The present utility model provides a technical solution: Refer to Figure 1 - Figure 7 , a linear easily tearable cooking bag disclosed by the present utility model includes a cooking bag body 1, and a sealing mechanism is provided at the top of the cooking bag body 1. The sealing mechanism includes a buckle 21. The top of the cooking bag body 1 is inserted into the buckle 21 and is in interference fit with the inner wall of the buckle 21. Two rubber rods 22 are oppositely arranged in the opening of the cooking bag body 1, and the two opening walls on the front and back sides of the cooking bag body 1 are both curved and are respectively fixedly connected to the outer peripheral walls of the two rubber rods 22, and the outer peripheral walls of the two rubber rods 22 are in interference fit;

[0026] An exhaust hole 23 with a T-shaped cross-section is provided at the middle position on the top side of the buckle 21, and a sealing mechanism 32 is provided in the exhaust hole 23.

[0027] In this embodiment, when the improved linear tearable cooking bag is in use, the operator puts the product into the cooking bag body through the top opening of the cooking bag body. Then the operator combines the two rubber rods, and then inserts the top of the cooking bag body into the buckle through the left-end opening of the buckle. At this time, due to the mutual contact between the inner wall of the buckle and the outer wall of the cooking bag body and the telescopic deformation of the rubber rods, the two rubber rods are closely attached together, thereby closing the opening end of the cooking bag body;

[0028] After the cooking bag is heated, if there is a large amount of water vapor in the cooking bag body 1, at this time the operator uses a towel as an isolation layer and presses the cooking bag body 1. As the cooking bag body 1 deforms and returns to its original position, a large pressure difference is generated on the upper and lower sides of the two rubber rods 22. Then, most of the water vapor in the cooking bag body 1 can be squeezed out of the cooking bag through the deformation and reset of the rubber rods 22. At the same time, the blocking mechanism 32 automatically releases the blocking state of the exhaust hole 23, and the water vapor is discharged to the outside through the exhaust hole 23. At this time, the operator pulls the buckle 21 away from the cooking bag body 1, and the top of the cooking bag body 1 slides out from the left-end opening of the buckle 21, and the sealing state of the opening end of the cooking bag body 1 is released. The opening operation of the cooking bag is relatively convenient. And when the opening operation of the cooking bag is carried out, the operator's hand will be near the opening of the cooking bag, and only a very small amount of high-temperature water vapor will flow out of the cooking bag. Therefore, it can prevent the operator's hand from being damaged by contacting the high-temperature water vapor;

[0029] When the remaining items in the cooking bag body 1 need to be reheated, the operator can put the buckle 21 on the opening end of the cooking bag again according to the above method, and then the sealing operation of the cooking bag body 1 can be completed again. The cooking bag can be reused for heating the remaining items inside, which is convenient for the purchaser to use.

[0030] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 2 shown, a blocking film 24 is provided on the left side of the buckle 21, and the blocking film 24 is fixedly connected to the buckle 21 through an adhesive, and the blocking film 24 is in contact with the cooking bag body 1;

[0031] In this embodiment, after the opening end of the cooking bag body 1 is inserted into the buckle 21, the operator uses adhesion to attach the blocking film 24 to the left end of the buckle 21 to close the left-end opening of the buckle 21. At this time, due to the mutual contact between the blocking film 24 and the cooking bag body 1, the top of the cooking bag body 1 will not slide out of the buckle 21, and the sealing operation of the cooking bag body 1 is completed. The purchaser can determine whether the cooking bag body 1 has been opened according to whether the blocking film 24 is damaged, so as to enhance the safety of the improved cooking bag when used for packaging food. The anti-counterfeiting code can also be printed on the blocking film 24 to further enhance the safety of the device.

[0032] In a further preferred embodiment of the present invention, Figure 1 , Figure 3 and Figure 6 As shown, the opening edge at the left end of the buckle 21 and the opening edge at the bottom side of the buckle 21 are both arranged in an arc shape, and the right side of the buckle 21 is arranged in a solid shape;

[0033] In this embodiment, the arc-shaped setting of the opening end of the buckle 21 enlarges the opening of the buckle 21, making it easier to insert the top of the cooking bag body 1 into the buckle 21, while avoiding the sharp corners of the opening end of the buckle 21 and the cooking bag body 1 from interfering with each other, thereby avoiding scratches on the surface of the cooking bag body 1 when installing the buckle 21.

[0034] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the blocking mechanism 32 includes a limit strip 31, which is slidably mounted in the exhaust hole 23, an elastic plate 32 is fixedly mounted on the top side of the limit strip 31, and the bottom side of the elastic plate 32 is in contact with the top side of the limit strip 31, the top view area of ​​the elastic plate 32 is larger than the top view area of ​​the exhaust hole 23, a plurality of elastic blocks 33 are relatively fixedly mounted on the bottom side of the limit strip 31, and the bottom end of each elastic block 33 is fixedly connected to the inner wall of the exhaust hole 23 by an adhesive;

[0035] In this embodiment, the water vapor discharged from the cooking bag body 1 will first flow into the exhaust hole 23. At this time, a pressure difference is generated between the upper and lower sides of the elastic plate 32. At this time, the elastic plate 32 is pushed upward. As the elastic block 33 is stretched and deformed, the elastic plate 32 is separated from the buckle 21. The water vapor in the buckle 21 passes through the air guide groove 34 and the gap between the elastic plate 32 and the buckle 21 and is discharged from the buckle 21 through the exhaust hole 23. The setting of the blocking mechanism 32 will not affect the discharge of water vapor.

[0036] After the sealing operation of the above-mentioned cooking bag is completed, the tightly fitting rubber rod 22 forms a first sealing barrier line. At the same time, due to the pulling of the elastic block 33 on the elastic plate 32, the elastic plate 32 and the buckle 21 are tightly fitted, thereby blocking the opening of the exhaust hole 23 to form a second sealing barrier line, thereby enhancing the sealing strength of the cooking bag.

[0037] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 and Figure 6 As shown, a plurality of air guide grooves 34 are provided on the front and rear inner walls of the exhaust hole 23, and the spacing between two adjacent air guide grooves 34 is equal. The air guide grooves 34 are located below the elastic plate 32;

[0038] In this embodiment, the arrangement of the air guide groove 34 can increase the amount of gas passing through the exhaust hole 23, thereby avoiding a significant reduction in the amount of gas passing through the exhaust hole 23 due to the slider arrangement in the exhaust hole 23, and preventing the water vapor from having too low a passing rate in the exhaust hole 23.

[0039] In a further preferred embodiment of the present utility model, as Figure 5 and Figure 7 shown, a sealing ring 35 is fixedly installed in the elastic plate 32, and the bottom side of the sealing ring 35 extends to the bottom side of the elastic plate 32 and is in interference fit with the top side of the buckle 21. The sealing ring 35 is sleeved on the outer peripheral side of a plurality of air guide grooves 34;

[0040] In this embodiment, during the process of the elastic plate 32 being attached to the buckle 21, due to the pressing of the elastic plate 32 on the sealing ring 35 and the mutual resistance between the sealing ring 35 and the buckle 21, the sealing ring 35 undergoes adaptive shrinkage deformation according to the contact position of the buckle 21, so that the sealing ring 35 is closely attached to the outer wall of the buckle 21, thereby enhancing the sealing effect of the elastic plate 32 on the exhaust hole 23.

[0041] Working principle: When the improved straight-line easy-to-tear cooking bag is in use, the operator first puts the product into the cooking bag body 1 through the top opening of the cooking bag body 1. Then the operator combines the two rubber rods 22, and then inserts the top of the cooking bag body 1 into the buckle 21 from the left opening of the buckle 21. At this time, due to the mutual resistance between the inner wall of the buckle 21 and the outer side wall of the cooking bag body 1 and the telescopic deformation of the rubber rods 22, the two rubber rods 22 are closely attached together. Then the operator uses adhesion to attach the sealing film 24 to the left end of the buckle 21 to close the left opening of the buckle 21. At this time, due to the mutual resistance between the sealing film 24 and the cooking bag body 1, the top of the cooking bag body 1 will not slide out of the buckle 21, and the sealing operation of the cooking bag body 1 is completed;

[0042] After the cooking bag is heated, if there is a lot of water vapor in the cooking bag body 1, at this time the operator uses a towel as an isolation layer to press the cooking bag body 1. As the cooking bag body 1 deforms and returns to its original shape, a large pressure difference is generated on the upper and lower sides of the two rubber rods 22. Thus, most of the water vapor in the cooking bag body 1 can be squeezed out of the cooking bag through the deformation and reset of the rubber rods 22. As the gas flows into the buckle 21, a pressure difference can be generated on the upper and lower sides of the elastic plate 32. At this time, the elastic plate 32 receives an upward thrust. As the elastic block 33 stretches and deforms, the elastic plate 32 separates from the buckle 21, and the water vapor in the buckle 21 passes through the air guide groove 34 and the gap between the elastic plate 32 and the buckle 21 and is discharged from the exhaust hole 23 of the buckle 21;

[0043] After most of the water vapor in the cooking bag body 1 is squeezed out, the elastic block 33 is deformed and reset, and the elastic plate 32 automatically moves toward the buckle 21 until the elastic plate 32 and the buckle 21 conflict with each other. At this time, due to the pressing of the elastic plate 32, the sealing ring 35 and the buckle 21 are tightly fitted, thereby re-blocking the exhaust port of the exhaust hole 23. Then, the operator tears off the blocking film 24 from the buckle 21, and then pulls the buckle 21 away from the cooking bag body 1. The top of the cooking bag body 1 slides out from the left end opening of the buckle 21, and the sealing state of the open end of the cooking bag body 1 is released;

[0044] When the articles in the retort bag body 1 need to be reheated, the operator reinstalls the buckle 21 according to the above, and the two rubber rods 22 are closely fitted to form a first sealing barrier line, and because the rubber rods 22 push the opening wall of the retort bag body 1, the outer wall of the opening end of the retort bag body 1 is closely fitted with the inner wall of the buckle 21, and the elastic plate 32 blocks the exhaust hole 23 to form a second sealing barrier line, so that the sealing operation of the retort bag can be completed again;

[0045] It should be noted that after the buckle 21 is put on the top of the cooking bag, due to the mutual interference between the outer wall of the cooking bag body 1 and the inner wall of the buckle 21, the friction force generated between the buckle 21 and the cooking bag body 1 can constrain and limit the cooking bag body 1 to the buckle 21, so that the buckle 21 is more stably put on the top of the cooking bag body 1.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
