[0029] The embodiments of the utility model will be described below by specific specific embodiments, and those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0030] As shown in Figures 1 to 5 , a sealed chewing gum box in the first aspect embodiment of the utility model, comprising upper cover 1 and lower cover 2, upper cover 1 and lower cover 2 are all made of metal material or plastic material and are integrally formed structure, upper cover 1 and lower cover 2 are buckled together to form disc-shaped container.

[0031] The bottom edge of the upper cover 1 is provided with a circular chamfer 11 extending inwardly, and the arc curvature radius R of the circular chamfer 11 satisfies 0.5mm≤R≤3mm. Preferably, the arc curvature radius R of the circular chamfer is 1.5mm. The cross-sectional shape of the circular chamfer 11 is an elliptical arc.

[0032] The top of the lower cover 2 is provided with a cylindrical boss 21 protruding outwardly, and the side wall of the cylindrical boss 21 is vertically arranged with the lower cover 2. The top end of the cylindrical boss 21 is provided with a circular arc transition section 211.

[0033] The upper edge of the cylindrical boss 21 forms a linear contact sealing fit with the lower edge of the circular chamfer 11. When the upper cover 1 and the lower cover 2 are buckled, the arc surface of the circular chamfer 11 elastically deforms to form an interference fit sealing structure with the side wall of the cylindrical boss 21, and the circular arc transition section 211 abuts against the inner wall of the upper cover 1 to form a secondary sealing structure.

[0034] The top of the upper cover 1 is provided with a downwardly recessed accommodating groove 3, and the accommodating groove 3 is provided with a taking-out port 311 and a mounting port 312, both of which are in communication with the above-mentioned sealing structure. The accommodating groove 3 is provided with a matching buckle arm 4, the bottom of the buckle arm 4 is provided with a sealing column 411 and a mounting column 412, the sealing column 411 is installed in the taking-out port 311, the mounting column 412 is installed in the mounting port 312, and the end of the buckle arm 4 close to the sealing column 411 can be bent along the thickness direction of the buckle arm 4 to the end of the buckle arm 4 close to the mounting column 412. The thickness of the buckle arm 4 is the same as the depth of the accommodating groove 3.

[0035] The linear contact sealing fit and interference fit of the circular chamfer 11 of the upper cover 1 with the cylindrical boss 21 of the lower cover 2 do not require additional sealing rings or glue, which fundamentally avoids the risk of harmful substance release that may be caused by traditional sealing methods, ensuring food safety. This sealing method can effectively prevent air and moisture from entering the box, creating a dry and stable storage environment for chewing gum, thereby better maintaining the dryness and freshness of the chewing gum and significantly prolonging the shelf life of the chewing gum. In addition, the product structure is simple, the production capacity has increased from the original 200,000 per day to 300,000 per day, and the cost has been reduced.

[0036] The arc curvature radius R of the circular chamfer 11 is preferably 1.5mm, which makes the force of buckling and opening the upper and lower covers moderate, ensuring the stability and reliability of the sealing structure, and facilitating user operation and improving the user experience. At the same time, the cross-sectional shape of the circular chamfer 11 is an elliptical arc, which has a larger contact area and better elastic deformation effect than ordinary circular arcs when cooperating with the cylindrical boss 21, further enhancing the sealing performance and more effectively blocking external substances from entering the box.

[0037] The circular arc transition section 211 at the top end of the cylindrical boss 21 plays a guiding role when the upper cover and the lower cover are buckled, reducing friction and resistance, making the buckling process smoother. And the circular arc transition section 211 abuts with the inner wall of the upper cover 1 to form a secondary sealing structure, further improving the sealing performance, preventing impurities from entering from the gap between the top end of the cylindrical boss and the inner wall of the upper cover, providing double sealing protection for chewing gum.

[0038] The structure design of the accommodating groove 3, the taking-out port 311, the mounting port 312 and the buckle arm 4 at the top of the upper cover 1 fully considers the use requirements of users. The buckle arm 4 is usually an elastic plate, and users only need to bend the end of the buckle arm 4 close to the sealing column 411 to open the taking-out port 311, and conveniently take out the chewing gum. After use, the buckle arm 4 can automatically restore the sealing state, ensuring the sealing environment in the box. The whole process is simple, convenient and sanitary, greatly improving the user's experience.

[0039] The upper cover 1 and the lower cover 2 are integrally formed by metal or plastic, reducing the connection parts and avoiding sealing problems caused by connection gaps, improving the overall sealing performance. At the same time, the integrated molding process enhances the structural strength, making the chewing gum box more durable, able to withstand certain external pressure and collision, not easy to damage, prolonging the service life of the product.

[0040] The upper cover 1 and the lower cover 2 are buckled together to form a disc-shaped container, which is beautiful and elegant in appearance, meeting the aesthetic needs of modern consumers for product appearance. Moreover, the disc-shaped design is more convenient to carry, and compared with other shapes, it is not easy to appear edge wear and other situations, making it convenient for consumers to carry and enjoy the pleasure experience of chewing gum anytime and anywhere.

[0041] The thickness of the buckle arm 4 is the same as the depth of the accommodating groove 3, which makes the buckle arm 4 flat in the accommodating groove 3, not only does not affect the overall appearance of the upper cover 1, but also ensures the stability and reliability of the buckle arm 4 in the bending and sealing process, so that it can better play the sealing role, and the structure design of the whole chewing gum box is complementary.

[0042] The upper cover 1 and the lower cover 2 of the sealing chewing gum box can be made of metal materials such as aluminum alloy, stainless steel, or plastic materials such as polypropylene and polyethylene according to actual needs and cost considerations. In this embodiment, polypropylene plastic is selected as the manufacturing material, which has good chemical corrosion resistance, toughness and processing performance.

[0043] The upper cover 1 and the lower cover 2 are made by injection molding process. When the upper cover 1 is made, the mold parameters are strictly controlled to ensure that the arc surface curvature radius R of the circular chamfer 11 meets the design requirements, and the cross-sectional shape is an elliptical arc. At the same time, the containing groove 3, the taking-out port 311 and the mounting port 312 are accurately processed. When the lower cover 2 is made, the side wall of the cylindrical boss 21 is perpendicular to the lower cover 2, and the size accuracy of the circular arc transition section 211 at the top end of the cylindrical boss 21 is ensured.

[0044] The buckle arm 4 is also made by injection molding process to ensure that the size of the sealing column 411 and the mounting column 412 is adapted to the taking-out port 311 and the mounting port 312.

[0045] The sealing column 411 of the buckle arm 4 is installed in the taking-out port 311, and the mounting column 412 is installed in the mounting port 312, so that the buckle arm 4 can be flexibly bent and has good sealing effect. Then the upper cover 1 and the lower cover 2 are buckled, the sealing effect of the line contact type sealing fit, interference fit and secondary sealing structure is checked, and if necessary, appropriate adjustment is made.

[0046] When the user needs to take the chewing gum, the end of the buckle arm 4 close to the sealing column 411 is pressed by the finger, so that it is bent along the thickness direction of the buckle arm 4 to the end close to the mounting column 412, so as to open the taking-out port 311 and take the chewing gum. After use, the buckle arm 4 is released, and the buckle arm 4 restores to the original state under the action of its own elasticity, and the sealing column 411 reseals the taking-out port 311. When it is necessary to open the whole chewing gum box for replenishing chewing gum or cleaning, the upper cover 1 is pulled up with appropriate force; when buckling, the upper cover 1 is aligned with the lower cover 2, and is pressed slightly, so that the circular chamfer 11 of the upper cover 1 forms a sealing fit with the cylindrical boss 21 of the lower cover 2.
