[0028] The upper film 2 and the bottom film 1 can be torn off the food box by lifting the opening A11 (it should be noted that the upper film 2 and the bottom film 1 do not need to be completely torn off from the instant food noodle box during use) to add water, and the opening B12 is convenient for tearing the separation layer B21 off the separation layer A13, thereby opening the water filter port to perform the water filtering operation, and the bottom film 1 and the upper film 2 adopt a multi-layer structure, and the multi-layer structure specifically adopts film (including PET, BOPP, PA, PE, etc.), paper (including all papers such as coated paper, offset paper, kraft paper, glassine paper, etc.), film (including PET, BOPP, PA, PE, etc.) from the inside to the outside, separation layer coating liquid (food grade), PE film (polyethylene, polypropylene), film (including PET, BOPP, PA, PE, etc.), aluminum foil, PE film (polyethylene, polypropylene).

[0029] It should be noted that the manufacturer can choose to use the above-mentioned multi-layer structure as needed. If it is just a simple change in order or removal of a layer, it is still within the protection scope of the present utility model.

[0030] The above-mentioned various films make the cover film have good mechanical strength, barrier properties and temperature resistance, which can effectively protect food, prevent the influence of external factors, and maintain food quality and taste. The paper set in front of the film can print product information, and at the same time can increase a certain stiffness and strength. The separation layer coating liquid can easily separate the cover film from the container when in use, which is convenient for consumers to open. The PE film has good sealing performance and flexibility, and can fit tightly to the container to prevent leakage of soup, etc. (improve protection). Aluminum foil has excellent barrier properties, including light barrier, air barrier, moisture barrier, etc., which can better maintain the freshness and flavor of food and extend the shelf life.

The water filter hole 14 is provided with a color-changing ink to enable it to have a color-changing function. After the water temperature is heated to a suitable temperature (specifically, the water temperature is heated for 3 to 5 minutes), the water filter hole 14 changes color, which plays an auxiliary reminder role, making it more convenient for consumers to use. B12 is opened from the inside to the outside (that is, opposite to the normal tearing direction), so as to adapt to machine production more flexibly. The separation layer B21 adopts a water-based separation layer with good adhesion, which can achieve separation, barrier or protection functions. Patterns and fonts can be printed on the surfaces where the separation layer A13 and the separation layer B21 are bonded to each other (of course, printing can also be chosen according to the needs of packaging).
