[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] A dust cover according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0028] like Figures 1-4 As shown, a dust cover according to an embodiment of the present invention includes a base 1, a fixing plate 2, a sealing cover 3, a cutting plate 4, and a measuring cup 5.

[0029] The installation process, which is understandable, is as follows:

[0030] First, install the base plate 1. Align the outward-protruding circular structure at the bottom of the base plate 1 precisely with the pre-set hole in the bag, and then snap it in to initially connect the dust cover to the bag.

[0031] Then, the fixing disc 2 is screwed on the bottom disc 1, and during the screwing, the fixing disc 2 is rotated to tightly fit with the bottom disc 1 until the screwing is completed, thereby fixing the bottom disc 1 and ensuring that the bottom disc 1 is stably installed on the bag.

[0032] Subsequently, the cutting plate 4 is clamped in the cover 3, specifically, the cutting plate 4 is clamped in the position pre-set on the inner wall of the cover 3, so that the cutting plate 4 is stable. At the same time, the measuring cup 5 is clamped on the inner wall of the cover 3, so that the measuring cup 5 is stably installed.

[0033] Finally, the cover 3 with the cutting plate 4 and the measuring cup 5 installed is screwed on the inner wall of the fixing disc 2, and the cover 3 is rotated to tightly fit with the fixing disc 2, thereby completing the installation of the dustproof cover.

[0034] Use process:

[0035] When the food needs to be taken, the cover 3 is held by hand, and the cover 3 is opened by rotating the outer wall of the cover 3.

[0036] If the bag has not been opened, the cutting plate 4 is rotated around the fixing structure of the cutting plate 4 itself at this time, and the cutting plate 4 is used to cut the surface of the bag to open the bag.

[0037] After the bag is opened, the measuring cup 5 clamped on the inner wall of the cover 3 can be used to take the appropriate amount of food from the bag.

[0038] After use, the cover 3 is screwed on the fixing disc 2 again, thereby realizing the dustproof storage of the food package.

[0039] In an embodiment of the utility model, as shown in Figures 1-4 The inner wall of the cover 3 is provided with a clamping groove 31, and the cutting plate 4 is clamped in the clamping groove 31.

[0040] It can be understood that when the dustproof cover for food packaging is assembled, the cutting plate 4 needs to be installed on the cover 3. The clamping groove 31 on the inner wall of the cover 3 is specially made for the cutting plate 4, and the shape and size of the clamping groove 31 perfectly match the edge profile of the cutting plate 4. During installation, the edge of the cutting plate 4 is accurately aligned with the clamping groove 31, and then pressure is slowly and uniformly applied to push the cutting plate 4 into the clamping groove 31. During the embedding process, the close fit between the cutting plate 4 and the clamping groove 31 can be obviously felt, until the cutting plate 4 is completely embedded in the clamping groove 31, the installation is completed, and the cutting plate 4 can be stably fixed on the inner wall of the cover 3 and will not shake or displace.

[0041] In an embodiment of the utility model, as shown in Figures 1-4 One side of the cutting plate 4 is provided with a fixing column 41, and the other end is provided with a blade 42. The cutting plate 4 rotates around the fixing column 41 as the center, and the blade 42 is used to cut the surface of the bag.

[0042] Wherein, it can be understood that since the cutting plate 4 is provided with a fixed column 41 at one side and a blade 42 at the other end, the fixed column 41 serves as the axis of rotation of the cutting plate 4, and before use, it needs to be ensured that it is stably in the corresponding fixed structure of the cover 3 to provide stable support for the subsequent rotation of the cutting plate 4.

[0043] Cutting circle operation: when the bag needs to be opened, the fixed column 41 is taken as the center, and the operator pinches the cutting plate 4 with fingers to slowly and smoothly rotate the cutting plate 4. During the rotation, the cutting plate 4 makes a circular motion with the fixed column 41 as the center, and the blade 42 at the other end gradually contacts the surface of the bag. With the continuous rotation of the cutting plate 4, the blade 42 performs a cutting circle operation on the surface of the bag.

[0044] In an embodiment of the present application, as shown in Figures 1-4 The inner wall of the cover 3 is also provided with a clamping column 32, which is matched with one side of the measuring cup 5 to realize the clamping of the two.

[0045] Wherein, it can be understood that when assembling the dustproof cover for food packaging, the measuring cup 5 is installed on the cover 3. The inner wall of the cover 3 is provided with a clamping column 32 in advance, and one side of the measuring cup 5 is designed to have a structure matched with the clamping column 32, which can be a groove or a bayonet. During installation, align the side of the measuring cup 5 with the matching structure with the clamping column 32 on the inner wall of the cover 3, and then gently push the measuring cup 5 so that the clamping column 32 is embedded in the corresponding structure of the measuring cup 5. With the gradual fit of the two, there will be a clear clamping feeling, ensuring that the measuring cup 5 is stably clamped on the inner wall of the cover 3 and will not easily fall off.

[0046] Preparation before use: when preparing to take food, when the cover 3 is opened by rotating the rotating groove 33 on the outer wall of the cover 3, the measuring cup 5 clamped on the inner wall of the cover 3 will move with the cover 3, and the measuring cup 5 will be in a position convenient for taking at this time, preparing for the subsequent taking of food.

[0047] Taking food: when taking food, since the measuring cup 5 has been stably clamped on the inner wall of the cover 3, directly holding the cover 3 will move the measuring cup 5 above the food packaging. Using the scale of the measuring cup 5, the appropriate amount of food can be directly taken from the food packaging. During the taking process, the clamping structure of the clamping column 32 and the measuring cup 5 can ensure that the measuring cup 5 is stably connected to the cover 3 and will not fall off due to shaking or improper operation, making it convenient for users to accurately measure and take.

[0048] In an embodiment of the present application, as shown in Figures 1-4 The outer wall of the cover 3 is provided with a rotating groove 33, and the cover 3 can be opened by rotating the rotating groove 33.

[0049] Wherein, it can be understood that the operator places fingers in the rotating groove 33, and slowly and uniformly applies a rotating force according to the reverse direction of the threaded connection of the cover 3 and the fixed disc 2, taking the rotating groove 33 as the force point. The rotating groove 33 drives the cover 3 to rotate together. Since the cover 3 and the fixed disc 2 are connected by threads, during the rotation process, the cover 3 gradually separates from the inner wall of the fixed disc 2 along the threads.

[0050] In an embodiment of the utility model, as shown in the figure, Figures 1-4 The dustproof function of food packaging is realized through the cooperation of the bottom disc 1, the fixed disc 2, the cover 3, the cutting plate 4 and the measuring cup 5, and the food is convenient to take.

[0051] Wherein, it can be understood that 1, the installation stage:

[0052] First, the circular structure of the bottom disc 1 protruding outward at the bottom is accurately aligned with the pre-set hole of the food packaging bag, and then it is clamped in with force, so that the bottom disc 1 is initially connected with the food packaging bag, providing a basis for subsequent fixation.

[0053] The fixed disc 2 is threadedly connected to the bottom disc 1, and the fixed disc 2 is tightly attached to the bottom disc 1 by rotating the fixed disc 2 until it is tightened, so that the bottom disc 1 is firmly fixed on the food packaging bag, preventing the bottom disc 1 from falling off and ensuring the stability of the entire dust cover system.

[0054] The cutting plate 4 is clamped into the clamping groove 31 pre-set in the inner wall of the cover 3, ensuring that the cutting plate 4 is stable and does not shake; at the same time, the measuring cup 5 is installed on the cover 3 by clamping with the clamping column 32 in the inner wall of the cover 3.

[0055] Finally, the cover 3 with the installed cutting plate 4 and measuring cup 5 is threadedly connected to the inner wall of the fixed disc 2, and the cover 3 is tightly matched with the fixed disc 2 by rotating the cover 3, completing the installation of the entire dust cover and forming a complete food packaging dustproof structure.

[0056] 2, daily storage stage:

[0057] After installation, since the bottom disc 1 is tightly clamped with the bag, the fixed disc 2 is further reinforced, and the cover 3 is threadedly connected with the fixed disc 2, forming a relatively sealed space, effectively preventing dust or small insects from entering the inside of the food packaging, and ensuring the hygiene and quality of the food.

[0058] 3, food taking stage:

[0059] When taking food, the operator holds the cover 3 with his hand, rotates the rotating groove 33 on the outer wall of the cover 3, and rotates in the opposite direction of the threaded connection of the cover 3 and the fixed disc 2, so that the cover 3 gradually separates from the inner wall of the fixed disc 2 and the cover 3 is opened.

[0060] After the food packaging bag is opened, the measuring cup 5 clamped on the inner wall of the cover 3 is directly used to take the appropriate amount of food from the food packaging bag, without the need for additional measuring tools, thereby improving the convenience of taking.

[0061] After the food is taken, the cover 3 is rotated in the opposite direction to the opening, and the cover 3 is rotated through the rotating groove 33 to be rethreadedly connected to the inner wall of the fixed disc 2, thereby forming a sealing structure again, achieving dustproof storage of the food packaging, and facilitating next time taking.

[0062] In summary, the dustproof cover of the embodiment of the present application has the advantages that the dustproof cover of the present application is clamped with the bag through the bottom disc, fixed through the fixed disc, and threadedly connected with the cover, thereby forming a good sealing structure, effectively preventing dust and insects, and cutting the plate to cut a suitable opening on the bag, thereby facilitating taking, and the clamping and rotating design is simple to operate, the measuring cup is provided to enable the user to measure without additional tools, and the use is more convenient.
