Description

Technical Field

[0001] This utility model relates to the field of aluminum can lid technology, and in particular to an aluminum can lid and an aluminum can container having the same. Background Technology

[0002] Aluminum can lids are key components used to seal aluminum can containers or similar containers, and they are widely used in the food, beverage, and daily chemical industries.

[0003] Depending on the application scenario, the design and specifications of aluminum can lids also vary. For example, easy-open aluminum can lids achieve convenient opening through pre-etched scoring lines and riveted pull rings. For instance, a lightweight aluminum packaging can lid and packaging container with application number 202420889690.X discloses an easy-open aluminum can lid, but it cannot be resealed after opening and does not have a resealable function.

[0004] For example, a resealable metal bottle cap with application number 202411935459.0 discloses filling the can through the filling port on the conical cap. Compared with the aluminum can, the metal cap can be screwed back on after being unscrewed, so that the beverage can be consumed in multiple servings. It has a resealable function. However, the metal cap is screwed onto the conical cap to form the filling port, which protrudes upward from the aluminum can container body. Its shape and structure no longer match the conventional aluminum can container with an easy-open lid. Utility Model Content

[0005] The purpose of this utility model is to provide an aluminum can lid and an aluminum can container having the same. A lower cover is provided on the lid body of the aluminum can lid. The lower cover is sealed by screwing the upper cover and the lower cover together. The bendable insert makes it easy to pinch and rotate with your fingers to screw the lid body and the lower cover together. Compared with the existing easy-open aluminum can lid, it can be repeatedly opened and closed, improving the convenience of use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an aluminum can lid, including a lid body, a through hole on the lid body, and further comprising:

[0007] The lower cover is disposed within the through hole and has a cavity penetrating its body. The inner wall of the cavity is provided with internal threads.

[0008] A soft rubber component is disposed on the lower cover and / or the cover body, with at least its upper portion embedded between the lower cover and the cover body, and at least its lower portion interference-fitting against the side wall of the lower part of the lower cover.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] like Figures 1 to 4As shown, an aluminum can lid includes a lid body 10 with a through hole 100. The aluminum can lid also includes a lower lid 20, a soft rubber part 30, and an upper lid 40. The lower lid 20 is disposed in the through hole 100 and has a cavity 200 penetrating its body. The inner wall of the cavity 200 has an internal thread 21. The soft rubber part 30 is disposed on the lower lid 20 and / or the lid body 10. Preferably, the soft rubber part 30 is disposed on the lower lid 20. At least the upper part of the soft rubber part 30 is embedded between the lower lid 20 and the lid body 10, and at least the lower part is press-fitted against the lower side wall of the lower lid 20. The upper lid 40 includes a lid body 41 and an insert 42 disposed at the upper end of the lid body 41. The insert 42 can be bent to form an angle with the lid body 41 and remain connected to the lid body 41. The lid body 41 has an external thread 411 and is screwed into the cavity 200.

[0031] In this invention, the aluminum can lid is applied to the aluminum can container, that is, the aluminum can container is sealed by the aluminum can lid. Combined with... Figure 6 As shown, when it is necessary to open the aluminum can lid, the insert 42 is bent to form an angle with the upper end face of the lid body 41. If the insert 42 is bent perpendicular to the upper end face of the lid body 41, the insert 42 can be pinched with fingers and rotated to drive the lid body 41 to rotate synchronously. The rotation of the lid body 41 relative to the lower lid 20 can cause the upper lid 40 to separate from the lower lid 20 after being separated from the cavity 200, and the aluminum can container is connected through the cavity 200. When the aluminum can lid needs to be closed, the lower part of the lid body 41 is inserted into the cavity 200, keeping the insert 42 bent and perpendicular to the upper end face of the lid body 41. By pinching the insert 42 with your fingers and rotating the insert 42 in the opposite direction, the lid body 41 can be rotated synchronously. The rotation of the lid body 41 relative to the lower lid 20 allows the upper lid to be inserted into the cavity 200. The lid body 41 can be screwed into the cavity 200 by the screwing of the external thread 411 and the internal thread 21. Then, the insert 42 is flipped to reset it, preventing the insert 42 from tilting up. This protects the insert 42 and keeps the upper end face of the upper lid 40 flush.

[0032] By setting a lower cover 20 on the lid body 10 of the aluminum can lid as described above, and sealing the lower cover 20 by screwing the upper cover 40 and the lower cover 20 together, the aluminum can lid and the aluminum can container are sealed. Compared with the existing easy-open aluminum can lid, it can be repeatedly opened and closed, improving the convenience of use.

[0033] Furthermore, since the cap body 41 is screwed into the cavity 200, the insert 42, which can be bent relative to the cap body 41, allows for easy rotation by pinching the insert 42 with fingers, thereby connecting the cap body 41 to the lower cap 20, improving ease of use. In addition, since the insert 42 is bent relative to the cap body 41, a crease will appear on the upper surface of the upper cap 40 after bending, indicating obvious signs of use, thus providing an anti-theft function and preventing its reuse on other aluminum can caps. Furthermore, the upper end of the upper cap 40 and the upper end of the lower cap 20 can be connected by welding, such as by a welding point. When used for the first time, the welding point will be damaged, causing the upper cap 40 and the lower cap 20 to separate. The damage to the welding point will also leave a mark, similarly providing an anti-theft function.

[0034] By using the soft rubber part 30, and taking advantage of its elastic material and deformation characteristics, the soft rubber part 30 can fill the gap between the lower cover 20 and the cover body 10, and make an interference fit with the lower cover 20 and the cover body 10, which can effectively seal the gap, block the outside air, and play the role of keeping food fresh and preventing leakage.

[0035] Preferably, the insert 42 includes a main body 421 and an end piece 422 disposed at the end of the main body 421. A groove 4101 is provided on one side of the upper end of the cover body 41, and a first slot 4102 is provided to connect the groove 4101 and the outside of the cover body 41. The end of the main body 421 away from the end piece 422 can be bent and connected to the cover body 41. After the insert 42 is bent, the main body 421 is embedded in the groove 4101, and the end piece 422 is embedded in the first slot 4102, and at least part of it protrudes laterally from the first slot 4102. In the above configuration, the groove 4101 can accommodate the main piece 421. When the main piece 421 is at least partially embedded in the groove 4101, at least part of its sidewall away from the end piece 422 can be connected to the sidewall of the groove 4101 away from the end piece 422, i.e., a lateral connection. This facilitates the connection between the main piece 421 and the cover body 41, and avoids the lifting phenomenon caused by the insert 42 being directly connected to the upper surface of the cover body 41. Preferably, the main piece 421 and the groove 4101 can be connected by a snap-fit. The end piece 422 is also embedded in the first slot 4102, and the two can also be connected by a snap-fit. Since the end of the end piece 422 protrudes from the first slot 4102, it is easy to pinch the end of the end piece 422 with your fingers and pull the end piece 422 upwards so that the end piece 422 and the main piece 421 are respectively disengaged from the first slot 4102 and the groove 4101.

[0036] Furthermore, the cross-sections of both the groove 4101 and the main body 421 are semi-circular, and the upper end face of the main body 421 is flush with the upper end face of the groove 4101, which can ensure the flatness of the upper end face of the cover 40.

[0037] Based on the above configuration, since the end of the main piece 421 is embedded in the groove 4101 and the end of the rear piece 422 protrudes from the first slot 4102, a second slot 2001 is provided on one side of the upper end of the lower cover 20, extending laterally through one side of the lower cover 20. When the upper cover 40 is closed on the lower cover 20, the end of the end piece 422 is embedded in the second slot 2001 and at least partially protrudes laterally from the second slot 2001. Similarly, it is convenient to pinch the end of the end piece 422 with fingers and pull the end piece 422 upward to disengage the end piece 422 from the second slot 2001 and the first slot 4102, and to disengage the main piece 421 from the groove 4101. Moreover, the cooperation between the end piece 422 and the second slot 2001 ensures the positional stability of the insert 42 and the upper cover 40 relative to the lower cover 20.

[0038] Preferably, the upper surface of the upper cover 40 is flush with the upper surface of the lower cover 20 to ensure the aesthetics of the connection between the two.

[0039] The upper end of the lower cover 20 is provided with at least one limiting groove 201 that communicates with the cavity 200. One side of the limiting groove 201 and the upper end face of the lower cover 20 are provided with an inclined connecting surface 2011. The upper side wall of the upper cover 40 (cover body 41) is provided with at least one limiting fin 412. When the upper cover 40 is closed on the lower cover 20, the limiting fin 412 is embedded in the limiting groove 201 and is located on the side of the inclined connecting surface 2011. When the upper cover 40 needs to be opened, the cover body 41 is rotated (by pinching the vertically positioned insert 42 with fingers). The limiting fin 412 can smoothly disengage from the limiting groove 201 through the guiding action of the inclined connecting surface 2011. When the upper cover 40 needs to be opened, the cover body 41 is rotated in the opposite direction. The limiting fin 412 can smoothly embed into the limiting groove 201 through the guiding action of the inclined connecting surface 2011. The limiting groove 201 limits the position of the limiting fin 412, thus preventing the upper cover 40 from rotating excessively within the lower cover 20. Furthermore, a stop groove 23 can be provided on the lower cover 20, and a stop block 413 can be provided on the cover body 41. The limiting cooperation between the stop block 413 and the stop groove 23 can also prevent the upper cover 40 from rotating excessively when it is closed on the lower cover 20.

[0040] Preferably, the cover body 41 and / or the insert 42 are provided with indicator marks, such as an indicator on the insert 42 for indicating the lifting position, and an indicator on the cover body 41 for indicating the rotation direction when opening.

[0041] For the connection between the lower cover 20 and the cover body 10, a slot 202 is provided on the side wall of the lower cover 20. The edge of the through hole 100 on the cover body 10 is engaged in the slot 202, which can position the lower cover 20 on the cover body 10.

[0042] Combination Figure 5 As shown, further, an extension ring 22 is provided on the side wall of the lower cover 20 below the slot 202. Two positioning wings 221 are provided on the outer side wall of the extension ring 22. The soft rubber part 30 includes an annular body 31 and an annular flange 32 disposed at the upper end of the annular body 31. An annular positioning groove 320 is formed between the upper part of the annular flange 32 and the annular body 31. Two positioning slots 3201 are provided on the annular flange 32. The annular body 31 is fitted onto the lower cover 20, and the extension ring 22 is embedded in the annular positioning groove 320 of the annular flange 32. Each positioning wing 331 is embedded in one of the two positioning slots 3201. The upper part of the annular flange 32 is in interference fit with the cover body 10, and the annular body 31 is in interference fit with the side wall of the lower cover 20. By wrapping the extension ring 22 with the annular flange 32 and embedding the positioning wing 221 into the positioning slot 3201, the soft rubber part 30 can be fixed to the lower cover 20. Thus, the upper part of the annular flange 32 abuts between the cover body 10 and the lower cover 20, which can fill the gap between the cover body 10 and the lower cover 20 and effectively ensure the sealing effect between the two.

[0043] In another embodiment of the present invention, an aluminum can container is also provided, including the aluminum can lid described above.
