Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically relating to a temperature-resistant and flame-retardant food packaging bag. Background Technology

[0002] Product packaging bags often need to maintain material stability during heat processing (such as high-temperature baking and steaming). High-temperature resistance is a fundamental requirement to ensure that packaging bags do not soften, deform, or melt at certain temperatures. To improve high-temperature resistance, heat-resistant plastics are usually selected, or the heat resistance of materials is enhanced through high-temperature treatment techniques.

[0003] While existing technologies use packaging bags to store beverages that need to be prepared, they cannot effectively expel air from the device during storage, which reduces the shelf life of the raw materials and makes them prone to spoilage. Therefore, those skilled in the art provide a heat-resistant and flame-retardant food packaging bag to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a food packaging bag with a simple structure and reasonable design that is heat-resistant and flame-retardant in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A heat-resistant and flame-retardant food packaging bag includes an outer packaging, an inner packaging fixedly connected to the inner wall of the outer packaging, a drinking mechanism fixedly connected to one side of the top of the inner packaging, an exhaust mechanism fixedly connected to the side wall of the outer packaging, and a handle fixedly connected to the top of the outer packaging.

[0007] As a further optimization of this utility model, the drinking mechanism includes a straw that is fixedly connected to the inside of the inner packaging, a drinking tube that is fixedly connected to the top of the straw, and a first sealing cap that is threaded onto the top of the drinking tube.

[0008] As a further optimization of this utility model, a limiting ring that cooperates with the first sealing cap is fixedly sleeved on the side wall of the drinking tube.

[0009] As a further optimization of this utility model, the exhaust mechanism includes an exhaust pipe that is fixedly inserted through the side wall of the outer packaging, and one end of the exhaust pipe is fixedly connected to the inside of the inner packaging.

[0010] As a further optimization of this utility model, a second sealing cap is threaded onto the side wall of the exhaust pipe.

[0011] As a further optimization of this utility model, a one-way valve is fixedly connected to the inner wall of the exhaust pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, after production is completed, the raw materials to be soaked are first added to the inner packaging. After the addition is completed, the air in the inner packaging is extracted through the exhaust pipe, so that the inside of the inner packaging is in a vacuum state. After the air is extracted, the exhaust pipe is sealed with a second sealing cap to further prevent air backflow and effectively prevent the raw materials from deteriorating during storage.

[0014] 2. In this utility model, when in use, the first sealing cover is opened, and water is injected into the drinking tube to soak the raw materials in the inner packaging. At the same time, the device can be carried by pulling the handle, and it also effectively avoids scalding when using hot water. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1: As Figure 1 - Figure 5As shown, a heat-resistant and flame-retardant food packaging bag includes an outer packaging 1, an inner packaging 2 fixedly connected to the inner wall of the outer packaging 1, and a handle 5 fixedly connected to the top of the outer packaging 1. The handle 5 and the outer packaging 1 are integrally formed, which can effectively prevent frostbite and burns during use and improve safety. A straw 7 is fixedly connected inside the inner packaging 2. The straw 7 is located at the eccentric position at the top of the inner packaging 2, which can effectively prevent contamination of the drinking tube 3 when using the handle 5. The top of the straw 7 is fixedly connected to the drinking tube 3. A first sealing cap 4 is threadedly fitted at the top of the drinking tube 3. A limiting ring 8 that cooperates with the first sealing cap 4 is fixedly fitted on the side wall of the drinking tube 3. When in use, the first sealing cap 4 is opened, and water is injected into the drinking tube 3 to soak the raw materials in the inner packaging 2. At the same time, the device can be carried by pulling the handle 5, which also effectively prevents burns when using hot water.

[0023] like Figure 1 - Figure 5 As shown, an exhaust pipe 9 is fixedly inserted through the side wall of the outer packaging 1. After production, the raw materials to be soaked are first added to the inner packaging 2. After the addition is completed, the air in the inner packaging 2 is extracted through the exhaust pipe 9, making the inside of the inner packaging 2 a vacuum state. After the air is extracted, the exhaust pipe 9 is sealed with the second sealing cap 6 to further prevent air backflow and effectively prevent the raw materials from deteriorating during storage. One end of the exhaust pipe 9 is fixedly connected to the inside of the inner packaging 2. The second sealing cap 6 is threaded onto the side wall of the exhaust pipe 9. A one-way valve 10 is fixedly connected to the inner wall of the exhaust pipe 9. The one-way valve 10 in the exhaust pipe 9 is made of conical rubber, which allows air to be discharged from the inner packaging 2. When a large amount of air enters the inner packaging from the outside, the exhaust pipe 9 is sealed with the second sealing cap 6. When in step 2, pressure is applied to the surface of the one-way valve 10 under air pressure, causing the one-way valve 10 to deform. During the deformation process, the small hole in the middle of the one-way valve 10 will be closed to prevent air backflow. Together with the second sealing cap 6, the sealing effect is further improved. When in use, the one-way valve 10 is used to expel air from the device, making its volume smaller and thus achieving portability. The inner packaging 2 is made of food-grade PP, which is in direct contact with food to ensure safety and provides good heat sealing performance. The outer packaging 1 is made of plastic material, which provides good mechanical strength and moderate temperature resistance. Aluminum foil is used between the outer packaging 1 and the inner packaging 2 to provide absolute barrier and further enhance the temperature resistance and flame retardant effect, effectively improving the temperature resistance and flame retardant effect of the food bag during use.

[0024] It should be noted that, in the case of this heat-resistant and flame-retardant food packaging bag, after production is completed, the raw materials to be soaked are first added to the inner packaging 2. After the filling is completed, the air in the inner packaging 2 is extracted through the exhaust pipe 9, making the inside of the inner packaging 2 a vacuum state. After the air is extracted, the exhaust pipe 9 is sealed with the second sealing cap 6 to further prevent air backflow and effectively prevent the raw materials from deteriorating during storage. When in use, the first sealing cap 4 is opened, and water is injected into the drinking tube 3 to soak the raw materials in the inner packaging 2. At the same time, the device can be carried by pulling the handle 5, which also effectively avoids scalding when using hot water.

[0025] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
