Description

Technical Field

[0001] The utility model belongs to the technical field of easy-tear covers, and particularly relates to an easy-tear cover with a corrosion-resistant structure. Background Art

[0002] Easy-tear lids, also known as easy-open lids, are metal packaging products with a pull tab for sealing packaging. Typically made of tinplate or aluminum, they are formed through processes such as punching, stretching, and rolling. They are coated with ultra-high-temperature sterilization-resistant metal or plastic composite films to ensure stability and safety during packaging. The scoreline design of the easy-tear lid is key to its ease of opening. The depth and shape of the scoreline are precisely calculated to ensure that the lid tears cleanly along the scoreline.

[0003] The existing easy-tear cover has the following problems during use:

[0004] Current easy-tear lids, when used to store metal parts like screws, offer great convenience during opening. However, once the sealing film is removed, the interior of the storage tube is completely exposed. Low humidity in these environments exacerbates metal corrosion, especially when corrosive gases or particles are present in the air. These corrosive agents can directly contact the metal surface, leading to oxidation, rust, and other corrosion phenomena. Utility Model Content

[0005] (1) Technical problems to be solved

[0006] In response to the shortcomings of the prior art, the present invention aims to provide an easy-tear lid with a corrosion-resistant structure. This easy-tear lid is designed to address the technical problem that, when used to store metal parts such as screws, the easy-tear lid provides great convenience when opened. However, once the sealing film is removed, the interior of the storage tube is completely exposed. In this case, low humidity exacerbates the corrosion process of the metal, especially when corrosive gases or particles are present in the air. These corrosive factors can directly contact the surface of the metal parts, leading to corrosion phenomena such as oxidation and rust.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the utility model provides an easy-tear cover with a corrosion-resistant structure, which includes an easy-tear cover body, a sealing film and a pull ring. The surface of the easy-tear cover body is connected to the sealing film, the surface of the sealing film is connected to the pull ring, the surface of the easy-tear cover body is connected to a plastic hinge, the surface of the plastic hinge is connected to a flip cover, the side surface of the flip cover is connected to a first handle, and the other side of the flip cover is connected to a second handle. The opening of the easy-tear cover body is connected to a first rubber ring, and the inner wall of the first rubber ring is provided with a groove.

[0009] When the easy-tear cover of the present technical solution is used, the first handle is subjected to a pulling force to drive the flip cover to rotate. When the flip cover rotates to the surface of the first rubber ring, it can be squeezed. The first rubber ring can be deformed by the squeezing. When the flip cover rotates to the inside of the groove, the first rubber ring can restore the deformation. In this way, a seal is formed between the flip cover and the easy-tear cover body through the first rubber ring.

[0010] Preferably, the flip cover forms a rotating structure with the easy-tear cover body through a plastic hinge. When the first handle is subjected to tension, the flip cover can drive the flip cover to generate tension. The first handle and the flip cover are an integrated structure, and the second handle and the flip cover are an integrated structure. When the flip cover is subjected to tension, it can rotate around the central axis of the plastic hinge as the center of the circle.

[0011] Furthermore, the inner wall of the easy-tear cover body is connected to an inner ring, the bottom side of the inner ring is connected to a second rubber ring, the interior of the easy-tear cover body is plugged with an extrusion ring, the outer side of the extrusion ring is connected to an internal threaded tube, and the surface of the easy-tear cover body close to the internal threaded tube is connected to an external thread.

[0012] Furthermore, the inner ring and the easy-tear cover body are an integrated structure, the external thread and the internal threaded tube are threadedly connected, and the internal threaded tube can move upward when the external threaded surface rotates, so that the height of the internal threaded tube can be adjusted.

[0013] Furthermore, the extrusion ring and the internal threaded tube are an integrated structure, and the upward movement of the internal threaded tube can drive the extrusion ring to move upward, and the upward movement of the extrusion ring can drive the extrusion of the second rubber ring.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] According to the utility model, after the sealing film is torn off, the first handle can be pulled. The first handle is pulled to drive the flip cover to rotate. When the flip cover rotates to the surface of the first rubber ring, it can be squeezed thereon. The first rubber ring can be deformed by the squeezing. When the flip cover rotates to the inside of the groove, the first rubber ring can recover its deformation. In this way, a seal is formed between the flip cover and the main body of the easy-tear cover by the first rubber ring, thereby preventing corrosion of metal parts caused by water vapor or corrosive gases in the air.

[0017] The utility model is that when installing the easy-tear cover, the main body of the easy-tear cover is first sleeved on the opening of the cylinder body, and then the internal threaded tube can be rotated. When the external threaded surface rotates, the internal threaded tube can move upward, and the upward movement of the internal threaded tube can drive the extrusion ring to move upward. The upward movement of the extrusion ring can drive the second rubber ring to be squeezed. The second rubber ring can be squeezed inwardly under the squeeze, so that the main body of the easy-tear cover can be fixed on the surface of the cylinder body by the deformation of the second rubber ring, thereby realizing the installation of the main body of the easy-tear cover.

The opening of the easy-tear cover body 1 is connected to a first rubber ring 8, and the inner wall of the first rubber ring 8 is provided with a groove 9.

[0027] The flip cover 5 forms a rotating structure with the easy-tear cover body 1 through the plastic hinge 4 , the first handle 6 and the flip cover 5 are an integral structure, and the second handle 7 and the flip cover 5 are an integral structure.

[0028] In addition, the inner wall of the easy-tear cover body 1 is connected to an inner ring 10, the bottom side of the inner ring 10 is connected to a second rubber ring 11, the interior of the easy-tear cover body 1 is inserted with an extrusion ring 12, the outer side of the extrusion ring 12 is connected to an internal threaded tube 13, and the surface of the easy-tear cover body 1 near the internal threaded tube 13 is connected with an external thread 14. The inner ring 10 and the easy-tear cover body 1 are an integrated structure, the external thread 14 and the internal threaded tube 13 are threadedly connected, and the extrusion ring 12 and the internal threaded tube 13 are an integrated structure.

[0029] Working principle: When using the device of the present technical solution, when it is necessary to take out the metal parts inside the storage cylinder, the pull ring 3 can be pulled at this time, and the sealing film 2 can be torn off through the pull ring 3. After the sealing film 2 is torn off and the metal parts are taken out, the first handle 6 can be pulled. The first handle 6 is subjected to tension, which can drive the flip cover 5 to generate tension. The flip cover 5 is subjected to tension and can rotate around the central axis of the plastic hinge 4 as the center of a circle. When the flip cover 5 rotates to the surface of the first rubber ring 8, it can be squeezed. The first rubber ring 8 can be deformed by being squeezed.
