Description

Technical Field

[0001] The utility model relates to an easy-open cover, in particular to a lightweight and easy-open can easy-open cover. Background Art

[0002] At present, the easy-open lid for canned food generally includes a lid body and a pull ring. The lid body is provided with an annular score line, which is arranged along the edge of the lid surface on the lid body and forms a pull lid. The riveted end of the pull ring is riveted to the edge of the pull lid by rivets, and the open end of the pull ring is directly opposite to the annular score line. The material of this lid body is iron. However, the iron easy-open lid has the disadvantages of large breaking force and large full opening force. Users need to spend a lot of effort to open the can. Since the iron cut is relatively sharp, the user's skin is often scratched. At the same time, the cut of the iron easy-open lid is exposed to the air, which is easy to rust in combination with water and air, shortening the storage period of the can. Utility Model Content

[0003] The problem to be solved by the utility model is to provide a light and easy-to-open can cover, which is light and easy to open, and improves the safety of use.

[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0005] A lightweight, easy-to-open canned easy-open cover comprises a cover body and a pull ring, wherein the cover body is provided with an annular score line, the annular score line is arranged on the cover body along the edge of the cover surface and forms a pull cover, the riveted end of the pull ring is riveted to the edge of the pull cover by a rivet, and the open end of the pull ring is directly opposite to the annular score line, and is characterized in that: the cover body is made of aluminum alloy; the upper surface of the cover body is coated with a wear-resistant coating, and the lower surface of the cover body is coated with a corrosion-resistant coating; the cover body is provided with a first reinforcing rib, a second reinforcing rib, and a third reinforcing rib in sequence from the outside to the inside, the first reinforcing rib protrudes upward and is located on the inner side of the annular score line, the riveted end of the pull ring is located between the two ends of the first reinforcing rib, the second reinforcing rib protrudes downward, the pulling end of the pull ring is located between the two ends of the second reinforcing rib, and the third reinforcing rib protrudes downward and is located below the pulling end of the pull ring.

[0006] Due to the low strength and light weight of aluminum alloy materials, aluminum alloy materials are easier to process and shape, making the aluminum alloy cut smoother than iron cuts. When users operate, the aluminum alloy cuts are not easy to pierce the skin or cause scratches, thereby improving the safety of use, making the opening force (i.e. the force required to start opening the lid) and the full opening force (the force required to completely open the lid) required for the aluminum alloy easy-open lid lower, reducing the difficulty of users when opening. In addition, a dense oxide film will form on the surface of the aluminum alloy to prevent the lid from oxidizing, and a corrosion-resistant coating is applied on the lower surface of the lid, thereby further improving the corrosion resistance of the aluminum alloy easy-open lid, helping to maintain the appearance and function of the easy-open lid stable, extending the service life of the product, and avoiding the influence of oxidation on the easy-open function. In addition, the first reinforcing rib, the second reinforcing rib, and the third reinforcing rib are sequentially arranged from the outside to the inside at the easily deformed position of the cover body, forming a bending stress structure arranged on the cover surface, which can play a role in strengthening the force at the center of the cover body, so as to strengthen the weak position of the easy-open cover and effectively solve the abnormalities such as deformation of the cover body during the sterilization process. Therefore, with the cooperation of the wear-resistant coating, the corrosion-resistant coating and the bending stress structure, the aluminum easy-open cover can completely replace the performance of the iron easy-open cover, and thus bring the advantage of being easier to open. Since the third reinforcing rib is convex downward and the third reinforcing rib is below the lifting end of the pull ring, some space is left below the lifting end of the pull ring, which is convenient for fingers to pull up the pull ring.

[0007] In a preferred embodiment, the cover body is provided with two oppositely arranged secondary score lines, the two secondary score lines are located inside the annular score line, and the inner ends of the two secondary score lines are close to the rivet, and the outer ends of the two secondary score lines extend from the inside to the outside along the bending direction of the annular score line. The secondary score lines are respectively provided on both sides close to the rivet, which can provide more bending points when the user opens the cover body, thereby reducing the opening force to a certain extent.

[0008] In a further preferred embodiment, the cover body is provided with two relatively arranged positioning reinforcement ribs, both of which are downwardly protruding and respectively located on the inner side of the corresponding secondary score lines, and the outer edges of the positioning reinforcement ribs extend from the inside to the outside along the bending direction of the corresponding secondary score lines; the riveted end of the pull ring is located between the two positioning reinforcement ribs, and the inner edge of the positioning reinforcement rib is in contact with the riveted end of the pull ring. The position where the two secondary score lines are located is a position where the easy-open cover is weak and easily deformed by stress. The positioning reinforcement ribs protruding downward are arranged near the secondary score lines, which can play a role in strengthening the stress at the position near the secondary score lines. The two positioning reinforcement ribs can strengthen the stress-bearing parts of the cover surface to the maximum extent, making it easier to open, and limiting the riveted end of the pull ring between the two positioning reinforcement ribs can further position the pull ring, making its riveting more stable and difficult to rotate around the rivet.

[0009] In a further preferred embodiment, the two positioning reinforcement ribs are respectively close to two ends of the second reinforcement rib.

[0010] In a preferred embodiment, the first reinforcing rib is C-shaped, and the riveted end of the pull ring is located in the opening of the first reinforcing rib.

[0011] In a further preferred embodiment, a first inclined surface gradually sloping downward from the inside to the outside is provided on the outer side edge of the first reinforcing rib, and a second inclined surface gradually sloping downward from the outside to the inside is provided on the inner side edge of the first reinforcing rib.

[0012] In a preferred embodiment, the second reinforcing rib is C-shaped, and the lifting end of the pull ring is located in the opening of the second reinforcing rib.

[0013] In a further preferred embodiment, a third inclined surface gradually sloping downward from the outside to the inside is provided on the outer side edge of the second reinforcing rib, and a fourth inclined surface gradually sloping downward from the inside to the outside is provided on the inner side edge of the second reinforcing rib.

[0014] In a preferred embodiment, the third reinforcing rib is provided with an annular inclined surface which gradually slopes downward from the outside to the inside.

[0015] In a preferred embodiment, the wear-resistant coating is a modified epoxy amino coating. The modified epoxy amino coating has high wear resistance and high temperature resistance, can effectively protect the upper surface of the cover body, prevent the cover body from being worn, and can effectively isolate the cover body from the external environment when the cover body is subjected to high temperature sterilization, preventing substances such as high temperature steam from entering the cover body.

[0016] In a preferred embodiment, the corrosion-resistant coating is an epoxy phenolic coating. The epoxy phenolic coating has high density and high temperature cooking resistance, can effectively block the cover and the contents, maintain the flavor of the product in the easy-open can, and prevent corrosion of the cover due to corrosion of the contents.

[0017] In a preferred embodiment, the aluminum alloy is 5182 aluminum alloy. The 5182 aluminum alloy has the properties of high strength, good corrosion resistance and good weldability.

[0018] Compared with the prior art, the utility model has the following advantages:

[0019] The utility model, with the cooperation of the wear-resistant coating, the corrosion-resistant coating and the bending stress structure, enables the aluminum easy-open cover to completely replace the performance of the iron easy-open cover, is light and easy to open, and improves the safety of use.

[0023] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-3 As shown, the lightweight and easy-to-open canned easy-open cover in this embodiment includes a cover body 1 and a pull ring 2. The cover body 1 is provided with an annular score line 11, which is arranged on the cover body 1 along the edge of the cover surface and forms a pull cover. The riveted end 21 of the pull ring 2 is riveted to the edge of the pull cover through a rivet 5, and the open end 22 of the pull ring 2 is opposite to the annular score line 11. The cover body 1 is made of aluminum alloy; the upper surface of the cover body 1 is coated with a wear-resistant coating 3, and the lower surface of the cover body 1 is coated with a corrosion-resistant coating. Coating 4; the cover body 1 is provided with a first reinforcing rib 12, a second reinforcing rib 13, and a third reinforcing rib 14 from the outside to the inside, the first reinforcing rib 12 protrudes upward and is located on the inner side of the annular score line 11, the riveted end 21 of the pull ring 2 is located between the two ends of the first reinforcing rib 12, the second reinforcing rib 13 protrudes downward, the pulling end 23 of the pull ring 2 is located between the two ends of the second reinforcing rib 13, and the third reinforcing rib 14 protrudes downward and is located below the pulling end 23 of the pull ring 2.

[0025] Since aluminum alloy materials have the characteristics of low strength and light weight, aluminum alloy materials are easier to process and shape, making the aluminum alloy cut smoother than iron cuts. When users operate, the aluminum alloy cuts are not easy to pierce the skin or cause scratches, thereby improving the safety of use, making the opening force (i.e. the force required to start opening the lid) and the full opening force (the force required to completely open the lid) required when opening the aluminum alloy easy-open lid lower, reducing the difficulty of users when opening. In addition, a dense oxide film will form on the surface of the aluminum alloy to prevent the lid body 1 from oxidizing, and a corrosion-resistant coating 4 is coated on the lower surface of the lid body 1, thereby further improving the corrosion resistance of the aluminum alloy easy-open lid, helping to maintain the appearance and function of the easy-open lid stable, extending the service life of the product, and avoiding the influence of oxidation on the easy-open function.

[0026] In addition, the first reinforcing rib 12, the second reinforcing rib 13, and the third reinforcing rib 14 are sequentially arranged from the outside to the inside at the easily deformed position of the cover body 1, forming a bending stress structure arranged on the cover surface, which can play a role in strengthening the force at the center of the cover body 1, so as to strengthen the weak position of the easy-open cover and effectively solve the abnormalities such as deformation of the cover body 1 during the sterilization process. Therefore, with the cooperation of the wear-resistant coating 3, the corrosion-resistant coating 4 and the bending stress structure, the aluminum easy-open cover can completely replace the performance of the iron easy-open cover, and thus bring the advantage of being easier to open. Since the third reinforcing rib 14 is convex downward and the third reinforcing rib 14 is below the lifting end 23 of the pull ring 2, some space is left below the lifting end 23 of the pull ring 2, so that it is convenient for fingers to pull up the pull ring 2.

The secondary score lines 15 are respectively provided on both sides close to the rivet 5, which can provide more bending points when the user opens the cover body 1, thereby reducing the opening force to a certain extent.

[0028] The cover body 1 is provided with two oppositely arranged positioning reinforcement ribs 16, both of which are downwardly protruding and respectively located on the inner side of the corresponding secondary score line 15, and the outer edge of the positioning reinforcement rib 16 extends from the inside to the outside along the bending direction of the corresponding secondary score line 15; the riveted end 21 of the pull ring 2 is located between the two positioning reinforcement ribs 16, and the inner edge of the positioning reinforcement rib 16 is in contact with the riveted end 21 of the pull ring 2. The position where the two secondary score lines 15 are located is a position where the easy-open cover is weak and easily deformed by force. The positioning reinforcement rib 16 protruding downward is arranged near the secondary score line 15, which can play a role in strengthening the force at the position near the secondary score line 15. The two positioning reinforcement ribs 16 can strengthen the stress-bearing part of the cover surface to the maximum extent, making it easier to open, and the riveted end 21 of the pull ring 2 is limited between the two positioning reinforcement ribs 16, which can further position the pull ring 2, making its riveting more stable and difficult to rotate around the rivet 5.

[0029] The two positioning reinforcement ribs 16 are respectively close to two ends of the second reinforcement rib 13 .

[0030] The first reinforcing rib 12 is C-shaped, and the riveted end 21 of the pull ring 2 is located in the opening of the first reinforcing rib 12 .
