[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0028] Example 1

[0029] This embodiment relates to a cover mounting structure, referring to... Figures 1-3 The system includes a lid body 100, a mounting part 200, and a decorative element 300. The lid body 100 can be used in products such as lunch boxes, plates, bowls, storage jars, or organizers to close the open ends of these products, providing sealing and protection for the contents. The mounting part 200 is recessed into the surface of the lid body 100 to position, fix, and remove the decorative element 300, preventing it from falling off or shifting during use. The decorative element 300 is detachably assembled within the mounting part 200, eliminating the need for adhesive or in-mold bonding. It allows for easy and quick installation and removal of the decorative element 300 without replacing the entire lid body 100. Furthermore, it has low manufacturing costs, high versatility, and meets the information transmission requirements of various occasions. It should be noted that the decorative element 300 can be a label, paper piece, film patch, or plastic nameplate, etc., without specific limitations.

[0030] Reference Figure 1 and Figure 4 Specifically, in this embodiment, both the cover body 100 and the mounting portion 200 can be circular or rectangular. In some embodiments, both the cover body 100 and the mounting portion 200 can also be elliptical or other polygonal shapes. Alternatively, the cover body 100 can be circular, and the mounting portion 200 can be rectangular.

[0031] In this embodiment, refer to Figures 2-3 The mounting section 200 is a mounting groove for accommodating and constraining the decorative element 300, preventing lateral displacement of the decorative element 300 and ensuring its stable position within the groove. It includes a groove body 210, a groove opening 220, and a groove bottom 230. The groove opening 220 surrounds the top of the groove body 210, serving as the loading and unloading entrance for the decorative element 300 and limiting its top position. The groove bottom 230 surrounds the bottom of the groove body 210, serving as a support surface for the decorative element 300, providing positioning and support. Since the area of ​​the groove bottom 230 is larger than the area of ​​the groove opening 220, and the area of ​​the groove bottom 230 is equal to the area of ​​the decorative element 300, the area of ​​the groove opening 220 is smaller than the area of ​​the decorative element 300, and the edge of the groove opening 220 will create a lateral obstruction to the decorative element 300. Then, under the action of external force, the decorative part 300 is deformed and inserted into the groove 220 and fixed on the bottom of the groove 230, so as to realize the quick installation of the decorative part 300.

[0032] In this embodiment, refer to Figure 3 The mounting part 200 also includes a first groove wall 240, which is inclinedly connected between the groove opening 220 and the groove bottom 230. The cross-section of the first groove wall 240 is V-shaped, and the inclined groove wall fits tightly against the side of the decorative part 300, preventing the decorative part 300 from shifting through the contact area and slight lateral pressure.

[0033] Specifically, in this embodiment, the inclination angle of the first groove wall 240 is 10°, which facilitates the slight deformation of the decorative part 300 before it is embedded and fixed in the groove bottom 230. This avoids excessive deformation of the decorative part 300 due to an excessively steep slope, while also preventing the decorative part 300 from being fixed if the slope is too small. In other embodiments, the inclination angle of the first groove wall 240 can also be 12°, 15°, 17°, 20°, 22°, 25°, 28°, 30°, etc., as long as the inclination angle of the first groove wall 240 is within the range of 10°-30°, and there is no need to specifically limit it here.

[0034] Specifically, in this embodiment, the height of the mounting part 200 is 2.5mm to accommodate decorative parts 300 of different thicknesses. In other embodiments, the height of the mounting part 200 may also be 2mm, 2.2mm, 2.6mm, 2.8mm, 3mm, 3.5mm, 3.7mm, 4mm, etc., as long as the height of the mounting part 200 is within the range of 2mm-4mm, and there is no need to specifically limit it here.

[0035] In this embodiment, the cover body 100 and the mounting part 200 are integrally formed. Specifically, the cover body 100 and the mounting part 200 are formed in one step by injection molding, which simplifies the production process and facilitates mass production. In other embodiments, the cover body 100 and the mounting part 200 may also be formed by splicing, etc.

[0036] Example 2

[0037] Reference Figure 5 This embodiment is basically the same as Embodiment 1, except that the mounting part 200 further includes a slot 250 and a second groove wall 260. The slot 250 is arranged along the depth direction perpendicular to the groove body 210, that is, the slot 250 is arranged laterally. The edge surface of the decorative piece 300 is tightly fitted with the inner wall of the slot 250 to secure the decorative piece 300 and prevent it from loosening within the mounting part 200. This embodiment provides a better constraint effect on the decorative piece 300 compared to Embodiment 1. The second groove wall 260 is inclinedly connected between the top of the slot 250 and the groove opening 220, making it easier for the decorative piece 300 to be embedded into the groove bottom 230 from the groove opening 220 along the second groove wall 260. Moreover, the second groove wall 260 can cooperate with the slot 250 to further constrain the decorative piece 300.

[0038] In this embodiment, the height of the slot 250 is greater than the thickness of the decorative part 300, which provides an assembly allowance for the decorative part 300 and facilitates easy loading and unloading.

[0039] Specifically, in this embodiment, the inclination angle of the second groove wall 260 is 8° to facilitate easy insertion of the decorative piece 300 into the slot 250. If the slope is too steep, the decorative piece 300 may deform due to excessive force when inserted into the mounting part 200. In other embodiments, the inclination angle of the second groove wall 260 may also be 5°, 6°, 7°, 9°, 10°, 11°, 12°, 13°, 14°, 15°, etc., as long as the inclination angle of the second groove wall 260 is within the range of 5°-15°, and there is no need to specifically limit it here.

[0040] Example 3

[0041] Reference Figure 6 This embodiment is basically the same as Embodiment 1, except that the mounting part 200 further includes a third groove wall 270, which is arc-shaped and connected between the groove opening 220 and the groove bottom 230. The third groove wall 270 has a certain curvature, and when the decorative part 300 is installed, the curved surface of the curved surface has better wrapping effect on the edge surface of the decorative part 300, preventing it from detaching from the groove opening 220. This embodiment has a better constraint effect on the decorative part 300 compared to Embodiment 1.
