[0031] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0032] Please see Figures 1 to 6 The present invention provides a metal and plastic composite cover, comprising an outer shell 1, a support body 2, a connector 3, and a sealing body 4, wherein the outer shell 1 is fitted over the support body 2;

[0033] The outer shell 1 includes an outer top plate 11, an outer side wall 12 and a limiting ring 13 connected in sequence, and the limiting ring 13 extends toward the central axis of the outer shell 1;

[0034] The support body 2 includes an inner top plate 21, an inner side wall 22, and a plurality of outward protrusions 23. The inner top plate 21 and the inner side wall 22 are connected to form a cavity 24. The plurality of outward protrusions 23 are provided on the inner side wall 22 and extend in a direction away from the central axis of the support body 2. The outward protrusions 23 abut against the outer shell 1, and the inner side wall 22 abuts against the limiting ring 13.

[0035] The connector 3 is disposed in the cavity 24 and is snapped into the inner top plate 21;

[0036] The connector 3 includes a first tube 31 and an annular groove 311 disposed on the first tube 31. The sealing body 4 includes a second tube 41, an inner ring 42 and an outer ring 43. The inner ring 42 is disposed on the inner surface of the second tube 41 and extends toward the central axis of the second tube 41. The first tube 31 is disposed inside the second tube 41. The inner ring 42 is disposed in the annular groove 311. The outer ring 43 is disposed on the outer surface of the second tube 41.

[0037] Specifically, in this embodiment, the structure of the metal and plastic composite cover is as follows: the support body 2 is connected to the connector 3, the sealing element 4 is sleeved on the connector 3, the support body 1 is connected to the outer shell 1, and the outer shell 1 is made of aluminum. Different patterns can be printed on the surface of the outer shell 1 according to different design requirements to meet different consumer needs. First, the support body 2 and the connector 3 are connected. Both the support body 2 and the connector 3 are injection molded from plastic material. The support body 2 includes an inner top plate 21 and an inner side wall 22. The inner side wall 22 is annular. After the inner top plate 21 and the inner side wall 22 are connected, they form a cavity 24. Component 3 includes a first tube 31, which is a hollow cylinder. One end of the first tube 31 is connected to the inner top plate 21 to connect the support 2 and the connector 3. Two annular grooves 311 are machined on the outer surface of the first tube 31. The two annular grooves 311 are arranged sequentially along the axial direction of the first tube 31 and are spaced apart. The sealing body 4 includes a second tube 41 and an inner ring 42. The second tube 41 is a hollow cylinder with one open end. The inner ring 42 protrudes from the inner surface of the second tube 41. There are two inner rings 42. The semi-finished product, consisting of a support body 2, connector 3, and seal body 4, is assembled within an annular groove 311. The outer wall 12 of the outer shell 1 has an annular structure, and the outer top plate 11 has a circular structure connected to the outer wall 12. The limiting ring 13 originates from the end of the outer wall 12 and extends away from it. After the support body 2, connector 3, and seal body 4 are connected, the semi-finished product is then connected to the outer shell 1. The inner top plate 21 fits against the outer top plate 11, and the inner side wall 22 fits against the outer wall 12. The inner side wall 22 is engaged within the limiting ring 1, achieving the desired effect. The connection between the shell 1 and the support 2 completes the combination of the shell 1, the support 2, the connector 3 and the sealing body 4 to form a metal and plastic composite cap. Preferably, several protruding strips 23 are processed on the inner sidewall 22. The protruding strips 23 are set close to the outer sidewall 12 to support the shell 1 and prevent the shell 1 from deforming. An outer ring 43 is processed on the outer surface of the second tube 41. The outer ring 43 extends in a direction away from the central axis of the second tube 41, so that the sealing body 4 can better seal the external bottle. Preferably, the sealing body 4 is made of waterproof silicone.

[0038] By setting up a metal and plastic composite cover consisting of a shell 1, a support 2, a connector 3, and a seal 4, the support 2, connector 3, and seal 4 serve as internal supports, providing the cover with resistance to deformation. The surface of the shell 1 can be processed with different patterns to meet different consumer needs. This composite cover structure achieves aesthetics while increasing resistance to deformation, extending the service life of the cover, and reducing production costs.

[0039] The inner top plate 21 is provided with a through hole 211, which penetrates the inner top plate 21 along its thickness direction. The connector 3 includes a buckle 32, which is located at the top of the first tube 31 and extends away from the central axis of the first tube 31. The buckle 32 passes through the through hole 211 and engages with the inner top plate 21. There are two through holes 211, which are symmetrically arranged. There are also two buckles 32, which are symmetrically arranged to facilitate the connection between the support body 2 and the connector 3.

[0040] The support body 2 also includes an inner column 25, which is connected to the inner top plate 21 and disposed in the cavity 24. The inner column 25 is disposed inside the first tube 31, and the first tube 31 is sleeved on the outer surface of the inner column 25 to support the first tube 31. That is, the setting of the inner column 25 increases the strength of the sealing body 4 and prevents the sealing element 4 from tilting during the sealing process of the external bottle, resulting in uneven sealing.

[0041] The support body 2 also includes several inner protruding strips 26. The inner protruding strips 26 are provided on the inner surface of the inner sidewall 22 and extend toward the cavity 24. The inner protruding strips 26 are connected to the inner column 25. Several inner protruding strips 26 are arranged in a ring array around the central axis of the support body 2. The arrangement of the inner protruding strips 26 enhances the structural strength of the inner sidewall 22.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
