[0034] The inner side top end of the screwing can cover 4 is provided with a can opening sealing block 12, and the can opening sealing block is sealed in the inner side of the can opening after the screwing can cover 4 is tightened on the metal can body 1, the can opening sealing block 12 is arranged at the inner side top end of the screwing can cover 4, and the can opening sealing block 12 is tightly sealed in the inner side of the can opening after the screwing can cover 4 is tightened on the metal can body 1, which further strengthens the overall sealing performance of the packaging can. The sealing rubber ring 7 at the end of the limiting ring-shaped part 2 cooperates to provide double sealing protection for the product in the can, effectively prevents product leakage and external material intrusion. The surface of the metal can body 1 is integrally formed with a concave reinforcing embedded groove 13, and the metal reinforcing can sleeve 3 is embedded in the reinforcing embedded groove 13, and the reinforcing embedded groove 13 is integrally formed on the surface of the metal can body 1 to provide a precise embedded position for the metal reinforcing can sleeve 3. Through the close cooperation with the metal reinforcing can sleeve 3, the overall structural strength of the metal can body 1 is enhanced, the stability of the packaging can when bearing external force is improved, the deformation of the can body is prevented, and the service life of the packaging can is prolonged.

[0035] The outer surface of the metal reinforced can sleeve 3 is uniformly provided with convex points 14 for preventing slipping when holding the can body, which increases the friction between the hand and the can body and makes holding more stable. Especially when the hand is wet or a larger holding force is needed to twist off the can lid, the hand can be effectively prevented from slipping, improving the convenience and safety of the user's operation.

[0036] The inner and outer surfaces of the metal can body 1 are provided with an environmentally friendly coating 15, which includes an inner anti-corrosion coating 16 and an outer anti-permeation coating 17. The inner anti-corrosion coating 16 can effectively prevent the metal can body 1 from being eroded by corrosive substances in the can and the external environment, protect the material of the metal can body 1 from being damaged, and prolong its service life. The outer anti-permeation coating 17 prevents external moisture, gas and other substances from penetrating into the metal can body 1, while preventing the smell and ingredients of the can contents from spreading outward, maintaining product quality and environmental cleanliness, and embodying the environmental protection concept.

[0037] Specifically, when the threaded can lid 4 is screwed onto the threaded can opening of the metal can body 1, the sealing rubber ring 7 at the end of the limiting ring-shaped part 2 is first squeezed, forming a sealed line between the threaded can lid 4 and the end of the limiting ring-shaped part 2, effectively preventing external air from entering the can through the gap between the can lid and the can opening. At the same time, the can opening sealing block 12 at the inner top end of the threaded can lid 4 closely fits the inner side of the can opening during the tightening process, further enhancing the sealing effect. The double-sealing design ensures that the can contents are fully isolated from the external air, preventing oxidation and moisture.

[0038] When the threaded can lid 4 needs to be twisted, the user can push the auxiliary twisting plate 6, and the directional sliding block 10 at the lower end of the auxiliary twisting plate 6 slides along the guide sliding groove 8 in the concave groove 5, ensuring its stable sliding direction. At the same time, the limiting block 11 at the lower end of the directional sliding block 10 slides in the limiting sliding groove 9, preventing the auxiliary twisting plate 6 from accidentally falling off during sliding. The user holds the auxiliary twisting plate 6 to twist, increasing the contact area and friction between the hand and the threaded can lid 4. In addition, the convex points 14 uniformly distributed on the outer surface of the metal reinforced can sleeve 3 further increase the friction between the hand and the can body when the user holds the can body, effectively solving the problem of difficult holding when the hand is sweaty, making the opening process easier.

[0039] The reinforcing groove 13 integrally formed on the surface of the can body 1 provides a precise embedding position for the metal reinforcing can sleeve 3. After the metal reinforcing can sleeve 3 is closely embedded in the reinforcing groove 13, the overall structural strength of the metal can body 1 is enhanced. When the metal reinforcing can sleeve 3 can disperse and bear part of the force when the metal can body 1 is frequently used or a user exerts a larger cap twisting force, effectively preventing the metal can body 1 from deforming. In addition, the environmental protection coating on the inner and outer surfaces of the metal can body 1 plays a role. The anticorrosive coating on the inner layer resists the corrosion of corrosive substances in the can and the external environment to the metal can body 1, and the impermeable coating on the outer layer prevents external water, gas and other substances from penetrating. From the aspects of structural reinforcement and surface protection, the service life of the metal can body 1 is prolonged, and the risk of packaging failure caused by can body damage is reduced.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
