Description

Technical Field

[0001] This utility model relates to the field of tin can design technology, and in particular to a moisture-proof and airtight tin can. Background Technology

[0002] In the packaging of food, pharmaceuticals, and other goods, tin cans are widely used due to their excellent sealing and corrosion resistance. Especially for items with high moisture requirements, sealing performance directly affects their shelf life and quality. However, as market demands for packaging reliability and durability continue to rise, traditional tin cans often experience sealing failures and deformation during long-term use, failing to meet the needs of high-end moisture-proof packaging. Therefore, structural innovation is urgently needed to improve sealing reliability and can strength.

[0003] Existing moisture-proof and airtight tin cans have significant technical defects: First, their sealing structure is rudimentary. Traditional tin cans often use simple threads or snap-fit ​​seals, which are prone to wear and tear after long-term use, leading to aging of the sealing ring and allowing moisture to seep in, causing the contents to become damp and deteriorate. Second, the can body lacks sufficient strength. Ordinary tin cans lack internal reinforcement structures, making them prone to deformation under external pressure, resulting in seal failure and making them unusable. Furthermore, the non-modular sealing design cannot adapt to the moisture-proof needs of different items, and improper force during disassembly can easily damage the can body, affecting its sealing performance and service life. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a moisture-proof and airtight tin can, which aims to solve the problems of easy seal failure and easy deformation of traditional tin cans.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A moisture-proof and airtight tin can includes a can body with an internal cavity containing a reinforcing component. Grooves are formed at the top of both sides, and through holes are formed on adjacent sides of the grooves at both ends. A limiting component is provided inside the grooves. A can lid is provided on the top side of the can body, and an annular groove is formed on the top side of the can body. A sealing ring is provided inside the annular groove, and the top side of the sealing ring is fixedly connected to the bottom side of the can lid. A handle is rotatably connected to the top side of the can lid.

[0007] Furthermore, the limiting component includes a spring, one end of which is connected to the adjacent side of the grooves at both ends, and the other end is connected to an inclined slider. A limiting rod is fixedly connected to the adjacent side of the inclined sliders at both ends, and the outer wall of the limiting rod is slidably connected to the inside of the through hole.

[0008] Furthermore, a rotating ring is rotatably connected to the top of the outer wall of the tank. Both the left and right ends of the top side of the rotating ring are provided with inclined grooves, and the opposite ends of the inclined sliders at both ends are located inside the inclined grooves at both ends.

[0009] Furthermore, a limiting sealing block is fixedly connected to the middle of the bottom side of the can lid, and limiting grooves are provided at both the left and right ends of the limiting sealing block.

[0010] Furthermore, the reinforcing component includes a spiral rib, and multiple reinforcing ribs are fixedly connected inside the spiral rib. A fixing ring is fixedly connected to the top side of the multiple reinforcing ribs and the spiral rib.

[0011] Furthermore, a base plate is fixedly connected to the bottom side of the multiple reinforcing ribs and the spiral ribs, and the bottom side of the base plate is provided with multiple through grooves.

[0012] Furthermore, the bottom side of the tank body is provided with multiple threaded grooves, and a second spring is provided inside the threaded groove. One end of the second spring is connected to the top side of the threaded groove, and the other end is connected to an abutment block.

[0013] Furthermore, a plurality of screws are provided on the bottom side of the base plate, and the top of the outer wall of the screws penetrates the through groove and is threadedly connected to the inner wall of the threaded groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the can lid is placed so that the limiting sealing block and sealing ring are in place. The rotating ring is rotated so that it contacts the inclined surface of the inclined slider and pushes the slider to move. This drives the limiting rod into the limiting groove to fix the limiting sealing block. The spring is compressed. When the rotating ring rotates back, the spring drives the reset, thus achieving a tight seal between the can body and the can lid, effectively preventing moisture from entering and ensuring the moisture-proof preservation of the goods.

[0016] 2. In this utility model, the spiral ribs and multiple reinforcing ribs inside the cavity enhance the overall sturdiness of the can, improve the tin can's resistance to compression and impact, and extend its service life. At the same time, the spiral ribs can be replaced by removing the screws, which facilitates can maintenance and maintains the strength of the can. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Reference Figure 1-3 This utility model provides an embodiment of a moisture-proof and airtight tin can, comprising a can body 1, an interior cavity 13 with spiral ribs 16 inside the cavity 13, grooves on the top of both sides, and through holes on adjacent sides of the grooves. A spring 7 is installed inside the grooves. A can lid 4 is provided on the top side of the can body 1, and an annular groove 9 is provided on the top side of the can body 1. A sealing ring 11 is installed inside the annular groove 9, and the top side of the sealing ring 11 is fixedly connected to the bottom side of the can lid 4. The top side of the can lid 4 is rotatably connected to... Handle 5, one end of spring 7 is connected to the side of the grooves at both ends, and the other end is connected to a sloping slider 6. A limit rod 8 is fixedly connected to the side of the sloping slider 6 at both ends. The outer wall of the limit rod 8 is slidably connected to the inside of the through hole. A rotating ring 3 is rotatably connected to the top of the outer wall of the tank body 1. Sloping grooves are opened at both ends of the top side of the rotating ring 3. The opposite ends of the sloping sliders 6 at both ends are located inside the sloping grooves at both ends. A limit sealing block 12 is fixedly connected to the middle of the bottom side of the tank cover 4. Limiting grooves 10 are opened at both ends of the limit sealing block 12.

[0026] Specifically, when using this type of moisture-proof and airtight tin can, the operating procedure revolves around the sealing and preservation of the items and the maintenance of the can body 1. First, place the items to be sealed into the can body 1, place the can lid 4 on the top side of the can body 1, and let the limiting sealing block 12 and the sealing ring 11 enter the can body 1 and the annular groove 9 respectively, so that the limiting groove 10 is aligned with the through hole. Rotate the rotating ring 3. Because the inclined slider 6 is in the inclined groove and the contact surface between the rotating ring 3 and the inclined slider 6 is inclined, the rotation pushes the inclined slider 6 to move, driving the limiting rod 8 into the limiting groove 10 to fix the limiting sealing block 12. At the same time, the spring 7 is compressed so that when the rotating ring 3 returns to its original position, it drives the inclined slider 6 and the limiting rod 8 to reset.

[0027] Reference Figure 1 , Figure 4 and Figure 5 The spiral rib 16 is internally fixedly connected with multiple reinforcing ribs 17. The top side of the multiple reinforcing ribs 17 and the spiral rib 16 is fixedly connected with a fixing ring 15. The bottom side of the multiple reinforcing ribs 17 and the spiral rib 16 is fixedly connected with a base plate 2. The bottom side of the base plate 2 is provided with multiple through grooves 18. The bottom side of the tank body 1 is provided with multiple threaded grooves 14. The inside of the threaded groove 14 is provided with a second spring 20. One end of the second spring 20 is connected to the top side of the threaded groove 14, and the other end is connected to an abutment block 21. The bottom side of the base plate 2 is provided with multiple screws 19. The top of the outer wall of the screw 19 passes through the through groove 18 and is threadedly connected to the inner wall of the threaded groove 14.

[0028] Specifically, the cavity 13 of the can body 1 is equipped with spiral ribs 16 and multiple reinforcing ribs 17, which can enhance the overall robustness of the can body 1 and extend the service life of the tin can. The bottom plate 2 and spiral ribs 16 can be removed by disassembling screws 19 to replace the spiral ribs 16. The spring 20 and the abutment block 21 inside the threaded groove 14 compress the spring 20 when the screw 19 is installed, causing it to continuously apply force to the screw 19 through the abutment block 21. This makes the outer thread of the screw 19 fit more tightly with the inner thread of the threaded groove 14, improving the installation stability of the spiral ribs 16.

[0029] Working principle: In use, first, place the items to be sealed and preserved into the inside of the container 1, then place the lid 4 on the top side of the container 1. Simultaneously, the limiting sealing block 12 and the sealing ring 11 should enter the container 1 and the annular groove 9 respectively, with the limiting groove 10 aligned with the through hole. Then, rotate the rotating ring 3. Since the inclined slider 6 is located inside the inclined groove, and the contact surfaces of the rotating ring 3 and the inclined slider 6 are both inclined surfaces, rotating the rotating ring 3 will push the inclined slider 6 to move, thereby driving the limiting rod 8 into the limiting groove 10, thus fixing the limiting sealing block 12. Simultaneously, as the inclined slider 6 moves, the spring 7 is compressed, allowing the rotating ring 3 to rotate back to its original position. When the inclined slider 6 and the limiting rod 8 are reset, the cavity 13 is equipped with a spiral rib 16 and multiple reinforcing ribs 17, which can improve the overall sturdiness of the can body 1, thereby increasing the overall service life of the tin can. The bottom plate 2 and the spiral rib 16 can be disassembled by removing the screw 19, and the spiral rib 16 can be replaced. A second spring 20 and an abutment block 21 are set inside the threaded groove 14. Therefore, when the screw 19 is installed, the second spring 20 will be compressed, so that the second spring 20 will continuously apply force to the screw 19 through the abutment block 21. At the same time, the threads on the outer wall of the screw 19 and the threads on the inner wall of the threaded groove 14 will fit more tightly, thereby improving the sturdiness of the spiral rib 16.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
