[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a solid-liquid separation food packaging bag, including an outer packaging body 1, a first bag body 4 and a second bag body 13 are fixedly connected inside the outer packaging body 1, a first sealing strip 5 is fixedly connected to one side of the connection between the first bag body 4 and the second bag body 13, a concave strip 6 is fixedly connected to one side of the first sealing strip 5, a second sealing strip 9 is fixedly connected to the other side of the connection between the first bag body 4 and the second bag body 13, a convex strip 10 is fixedly connected to one side of the second sealing strip 9, and an intercepting net bag 14 is fixedly connected to the inside of the second bag body 13.
[0032] Specifically, the outer packaging body 1 serves as the external structure of the entire packaging bag, ensuring the stability and sealing of the two inner bags, the first bag body 4 and the second bag body 13. The first sealing strip 5 and the second sealing strip 9 are respectively fixed on the corresponding sides of the first bag body 4 and the second bag body 13, providing the structure required for sealing. The shape and size of the concave strip 6 match the convex strip 10, which is used to accommodate the convex strip 10 during compression, thereby achieving sealing. The convex strip 10 and the concave strip 6 are interlocked with each other during compression to provide a sealing effect for the liquid. The intercepting net bag 14 is fixedly connected to the inside of the second bag body 13, and its function is to prevent solid materials from entering the second bag body 13 while allowing liquid to pass through. When solid and liquid need to be mixed, the user can easily separate the first sealing strip 5 and the second sealing strip 9 by pulling the stretch belt 7 to separate the convex strip 10 from the concave strip 6.
[0033] Refer to the figure, Figure 4 and Figure 5 An aluminum foil 11 is fixedly connected to the inner side of the first bag body 4, a polypropylene 16 is fixedly connected to one side of the aluminum foil 11, and a paper 15 is fixedly connected to one side of the polypropylene 16. An aluminum foil 11 is fixedly connected to the inner side of the second bag body 13, a polypropylene 16 is fixedly connected to one side of the aluminum foil 11, and a polyethylene 17 is fixedly connected to one side of the polypropylene 16.
[0034] Specifically, the aluminum foil 11 serves as a barrier layer and is fixedly connected to the inner side of the first bag body 4 and the second bag body 13 to ensure that there is no gap between the aluminum foil 11 and the bag body. The polypropylene 16 layer serves as a layer adjacent to the aluminum foil 11, and the polyethylene 17 layer provides good sealing and chemical resistance to ensure the safety of liquid materials. When the convex strip 10 is inserted into the concave strip 6, a tight sealing structure is formed to prevent liquid leakage. The interception net bag 14 is fixedly connected to the inside of the second bag body 13, which can effectively prevent solid materials from entering the second bag body 13. When the user needs to mix solid and liquid, the convex strip 10 and the concave strip 6 can be easily separated by pulling the stretch belt 7 to break the seal.
[0035] Reference Figure 3 The other sides of the first sealing strip 5 and the second sealing strip 9 are fixedly connected with a stretching belt 7, one side of the two stretching belts 7 is provided with a pull ring 8, the outside of the convex strips 10 are provided with protrusions, the inside of the concave strips 6 are provided with grooves, the corresponding positions of the outside of the convex strips 10 are fitted with the inside of the concave strips 6, a cavity 12 is provided inside the outer packaging body 1, stretching belts 7 are provided on both sides of the outer packaging body 1, a sealing edge 2 is provided on the top of the outer packaging body 1, and an easy-tear strip 3 is fixedly connected to the outside of the sealing edge 2.
[0036] Specifically, the user holds the pull ring 8 to pull the stretch band 7, so that the user can easily separate the sealing strip by pulling. When the convex strip 10 is squeezed into the concave strip 6, the protrusion fits tightly with the concave strip to form a sealing structure, which effectively prevents liquid leakage. The cavity 12 opened inside the outer packaging body 1 is used to accommodate the first bag body 4 and the second bag body 13. When the user needs to open the packaging bag, the sealing edge 2 can be easily torn along the tear strip 3, which improves the user's convenience and ensures the sealing and safety of the packaging bag before it is opened.
[0037] Reference Figure 4 One side of the paper 15 is fixedly connected to the inner side of the first bag body 4, the thickness of the aluminum foil 11, the polypropylene 16 and the paper 15 are all 0.5 mm, one side of the polyethylene 17 is fixedly connected to the inner side of the second bag body 13, and the thickness of the polyethylene 17 is 0.5 mm.
[0038] Specifically, the design of the paper 15 ensures that the first bag body 4 has sufficient durability while maintaining the lightness of the package. The aluminum foil 11 and polypropylene 16 serve as important barrier layers to ensure the barrier properties and durability of the packaging bag. The polyethylene 17 has sufficient strength and durability while maintaining the lightness and flexibility of the package.
[0039] Working principle: when the liquid material needs to pass through the first bag body 4 into the second bag body 13, the first sealing strip 5 and the second sealing strip 9 are pressed relative to each other so that the convex strip 10 is inserted into the concave strip 6, thereby sealing the liquid in the second bag body 13, and then the solid is put into the first bag body 4, and then the sealing edge 2 is closed to seal the whole, so that the solid and liquid are completely placed in the outer packaging body 1;
[0040] Secondly, when it is necessary to mix the solid and the liquid, the outer packaging body 1 is turned over, and by pulling the stretch belt 7, the second sealing strip 9 drives the convex strip 10 to separate from the inside of the concave strip 6. At the same time, the liquid inside the second bag body 13 is squeezed by external force to enter the inside of the first bag body 4 through the interception net bag 14. At the same time, under the connection of the interception net bag 14, the solid cannot enter the inside of the second bag body 13, thereby achieving mixing between the solid and the liquid.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
