Description

Technical Field

[0001] This utility model relates to the field of easy-open lid technology, specifically to an SOT easy-open lid pull ring structure. Background Technology

[0002] SOT easy-open caps, also known as flip-top easy-open caps, are can caps with serrations on the opening area and a pull tab for easy opening. A key feature is that the pull tab remains attached to the cap after opening and does not detach. This design ensures the pull tab does not separate from the cap, improving the environmental friendliness of the easy-open cap. SOT easy-open caps are typically made of aluminum alloy and are commonly used in beer or carbonated beverage cans.

[0003] However, existing SOT easy-open covers have the following problems during use: Opening the SOT easy-open cover requires the user to lift the pull ring and press down on the opening at the end of the ring to fold open the sealing piece. However, in actual operation, there is a certain probability that the pull ring will separate and break off from the cover during the lifting and pressing process, making the cover impossible to open. This may be due to prolonged storage or corrosion of the easy-open cover, and there is a lack of corresponding solutions. Therefore, a corresponding technical solution needs to be designed to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a pull ring structure for SOT easy-open lids, which solves the problem that in the past, opening the SOT easy-open lid required the user to lift the pull ring and press down on the opening at the end of the pull ring to fold open the sealing piece. However, in actual operation, there is a certain probability that the pull ring will separate and break off from the lid during the lifting and pressing process, making the lid unable to be opened. This may be due to the easy-open lid being stored for too long or being corroded. There is a lack of corresponding treatment methods to address this technical problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an SOT easy-open cover pull ring structure, comprising an easy-open cover body and an opening on the easy-open cover body, a sealing piece provided at the opening, and an opening pull ring provided on one side of the opening, the opening pull ring comprising a ring body and a finger hole provided at the tail of the ring body, a pressure plate formed at the front end of the ring body and a groove formed in the middle, a connecting piece machined in the groove, a connecting rod inserted through the connecting piece, the connecting rod being fixed to the easy-open cover body, a hanging rod also being fixed at the front end of the pressure plate, a fixing piece fixed on the sealing piece, the fixing piece having a hanging hole and being used in conjunction with the hanging rod, the sealing piece comprising an outer ring and a sealing plate provided inside the outer ring, a plurality of sets of mating grooves machined on the outer ring and integrally formed with the inner wall of the opening, and mating protrusions machined on the edge of the sealing plate, the mating protrusions being located in the mating grooves and connected to each other.

[0006] In a preferred embodiment of this invention, the diameter of the tail end of the opening pull ring is larger than the diameter of the front end, and the front end of the opening pull ring is located directly above the sealing plate.

[0007] In a preferred embodiment of this utility model, the sealing plate located directly below the tablet is formed with several sets of stacked grooves, which are distributed in a stacked manner.

[0008] In a preferred embodiment of this invention, the thickness of the mating protrusion is less than the thickness of the outer ring, and the thickness of the mating protrusion is less than the thickness of the sealing plate.

[0009] In a preferred embodiment of this utility model, the hanging rod has a hook-shaped structure and a spherical end, and the diameter of the hanging rod is smaller than the diameter of the hanging hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model improves the existing SOT easy-open cover pull ring structure by designing a structure on the pull ring of the cover to facilitate the opening of the sealing piece, which can effectively improve the effort-saving and convenience of the pull ring for opening the cover. In addition, a traction opening mechanism is provided at the connection between the pull ring and the sealing piece. When the pull ring breaks and detaches from the cover, the sealing piece can be opened with the assistance of the traction opening mechanism.

[0012] 2. The pull ring structure of the easy-open lid designed in this utility model can improve the convenience and effort of opening the pull ring, and can open the lid even if the pull ring breaks. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an SOT easy-open cover pull ring structure, including an easy-open cover body 1 and an opening 2 on the easy-open cover body 1. A sealing piece 3 is provided at the opening 2, and an opening pull ring is provided on one side of the opening 2. The opening pull ring includes a ring body 4 and a finger hole 5 at the tail of the ring body 4. A pressure piece 6 is formed at the front end of the ring body 4, and a groove 7 is formed in the middle. A connecting piece 8 is machined in the groove 7, and a connecting rod 9 is inserted through the connecting piece 8 and fixed. On the easy-open cover body 1, a hanging rod 10 is fixed to the front end of the pressure plate 6, and a fixing plate 11 is fixed on the sealing plate 3. The fixing plate 11 has a hanging hole 12 and is used in conjunction with the hanging rod 10. The sealing plate 3 includes an outer ring 13 and a sealing plate 14 disposed inside the outer ring 13. Several sets of docking grooves 15 are machined on the outer ring 13 and are integrally formed with the inner wall of the opening 2. The edge of the sealing plate 14 is machined with docking protrusions 16. The docking protrusions 16 are located in the docking grooves 15 and the two are connected.

[0019] Further improvements, such as Figure 1 As shown, the diameter of the tail of the opening pull ring is larger than the diameter of the front end, and the front end of the opening pull ring is located directly above the sealing plate 3, which makes it easy to press down the sealing plate 3 to open.

[0020] Further improvements, such as Figure 2 As shown, the sealing disc 14 located directly below the tablet press 6 has several sets of stacked grooves 17. These stacked grooves 17 are distributed in a stacked manner, which facilitates the pressing of the tablet press 6 to press down on the sealing disc 14, causing the sealing disc 14 to bend inward and open.

[0021] Further improvements, such as Figure 2 As shown, the thickness of the mating protrusion 16 is less than the thickness of the outer ring 13, and the thickness of the mating protrusion 16 is less than the thickness of the sealing plate 14. This design makes it easier to open the sealing plate 14.

[0022] Specifically, the hanging rod 10 has a hook-shaped structure and a spherical structure at the end. The diameter of the hanging rod 10 is smaller than the diameter of the hanging hole 12. This design makes it easy for the hanging rod 10 to be hung in the hanging hole 12. At this time, the user can open it by pulling the broken opening ring and the sealing piece 3.

[0023] When in use: When it is necessary to open the opening 2, the user inserts his hand into the finger hole 5 and lifts the end of the opening pull ring to open it. During the lifting process, the pressure plate 6 moves downward and presses down on the sealing plate 14, causing the sealing plate 14 to press inward and open. If the opening pull ring breaks during the opening process, the user can insert the hanging rod 10 into the hanging hole 12. At this time, the sealing plate 14 can be opened by pulling the opening pull ring, thus achieving the purpose of opening the cover of the broken pull ring.
