Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and more specifically, to a packaging can for corrosive liquids. Background Technology

[0002] The safety of packaging containers for corrosive liquids is of paramount importance. Packaging cans for corrosive liquids not only need to have excellent corrosion resistance to prevent the can body from being corroded and leaking, but also need to ensure the reliability of the seal and the safety of operation in terms of structural design, so as to protect the safety of personnel and the environment. At present, most of the packaging cans commonly seen on the market adopt a screw-on lid connection structure.

[0003] However, the traditional screw-on packaging cans are too simple and direct to open, usually just by turning them. This makes it easy for non-professionals, especially children, to open the packaging. Because children are curious and lack awareness of danger, this easy-to-open feature may lead to accidents such as accidental opening and contact with corrosive liquids inside the can, posing a certain safety hazard.

[0004] In view of this, we propose a packaging container for corrosive liquids. Utility Model Content

[0005] Technical problems to be solved The purpose of this invention is to provide a packaging container for corrosive liquids, in order to solve the problem mentioned in the background art that traditional threaded packaging containers for corrosive liquids are too easy to open and pose safety hazards.

[0006] Technical solution

[0007] A packaging container for a corrosive liquid includes a container body and a cover plate detachably connected to the top of the container body. The container body has a layered structure. A limiting post with a size adapted to the container body is fixedly connected to the bottom of the cover plate. A limiting component and a connecting component are provided between the container body and the cover plate. The limiting component is used to limit the container body and the cover plate in the vertical direction, and the connecting component is used to fix the container body and the cover plate in the horizontal direction.

[0008] Preferably, the limiting component includes two symmetrically arranged limiting rods fixedly connected to the bottom of the limiting post, each of the two limiting rods being fixedly connected to a limiting block, and a limiting ring being fixedly connected inside the tank. The limiting ring has two vertically arranged through slots and two horizontally arranged limiting grooves.

[0009] Preferably, the two through slots and the two limiting slots are symmetrically arranged, and the through slots and limiting slots on the same side are connected. The width of the through slot is the same as the width of the limiting block, the limiting slot is arc-shaped, and the thickness of the limiting slot is the same as the thickness of the limiting block.

[0010] Preferably, the connecting assembly includes a first connecting block fixedly connected to the tank body and a second connecting block fixedly connected to the cover plate. The second connecting block is fixedly connected to an insert block, and the first connecting block has two slots that are adapted to the size of the insert block. The insert block is elastically connected to a locking block by a spring.

[0011] Preferably, the tank body is provided with a pointer for indicating the unlocking direction of the limiting component.

[0012] Preferably, the cover plate has an alignment groove that matches the size of the tank, and a rubber gasket is fixedly connected in the alignment groove.

[0013] Preferably, the tank body has an inner liner, a buffer layer and an outer shell from the inside to the outside. The inner liner is made of polytetrafluoroethylene, the buffer layer is made of silicone, and the outer shell is made of aluminum alloy. Beneficial effects

[0014] Compared with existing technologies, the advantages of this utility model are: This invention increases the difficulty of opening the cover and can by setting up limiting components and connecting components, which can effectively prevent children and other non-professionals from opening the packaging can too easily, avoid the risk of accidental contact with and ingestion of corrosive liquids inside the can, and improve the safety of the packaging can.

[0015] This invention achieves an axial seal when the cover plate contacts the can body by setting the alignment groove of the rubber gasket. It also achieves rigid fixation of the cover plate and the can body in the horizontal direction by connecting components, ensuring the stability of the connection between the cover plate and the can body and the reliability of the seal when the packaging can is transported, stored or accidentally dropped.

[0016] The can of this utility model adopts a composite structure consisting of an inner liner, a buffer layer and an outer shell, which extends the service life of the packaging can. In addition, the directional indicator on the can provides users with clear guidance on the opening direction, reducing the complexity of operation and improving the practicality of the packaging can.

[0020] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-7 This utility model provides a technical solution: A packaging container for a corrosive liquid includes a container body 1 and a cover plate 11 detachably connected to the top of the container body 1. The container body 1 is used to hold the liquid, and the cover plate 11 is used to seal the container body 1. The container body 1 has a layered structure. A limiting post 13 of a size adapted to the container body 1 is fixedly connected to the bottom of the cover plate 11. A limiting component 2 and a connecting component 3 are provided between the container body 1 and the cover plate 11. The limiting component 2 is used to limit the container body 1 and the cover plate 11 in the vertical direction, and the connecting component 3 is used to fix the container body 1 and the cover plate 11 in the horizontal direction. That is, the main function of the limiting component 2 is to prevent the cover plate 11 from accidentally coming loose in the vertical direction, while the connecting component 3 is used to firmly lock the cover plate 1 to the container body 1 in the horizontal direction, that is, in the circumferential direction, after the cover plate 11 is fastened, forming a complete sealed packaging unit.

[0023] Specifically, the limiting assembly 2 includes two symmetrically arranged limiting rods 21 fixedly connected to the bottom of the limiting post 13. Each limiting rod 21 is fixedly connected to a limiting block 22. A limiting ring 23 is fixedly connected inside the tank body 1. The limiting ring 23 has two vertically arranged through grooves 24 and two horizontally arranged limiting grooves 25. In specific implementation, two limiting rods 21 are radially symmetrically fixedly connected to the bottom end of the limiting post 13 that extends into the tank body 1. A limiting block 22 is fixedly fixed at the bottom of each limiting rod 21. Correspondingly, a limiting ring 23 is fixedly installed on the inner wall of the tank body 1 near the opening. The limiting ring 23 has two continuous grooves that are first vertical and then horizontally curved. The vertical part is the through groove 24, which allows the limiting block 22 to be inserted or lifted, while the horizontal part is the limiting groove 25, which is used to accommodate and restrict the horizontal movement of the limiting block 22.

[0024] Secondly, the two through slots 24 and the two limiting slots 25 are symmetrically arranged. The through slots 24 and the limiting slots 25 on the same side are connected. The width of the through slot 24 is the same as the width of the limiting block 22. The limiting slot 25 is arc-shaped and the thickness of the limiting slot 25 is the same as the thickness of the limiting block 22. The through slots 24 and the limiting slots 25 are connected end to end to form an L-shaped guide path. The limiting slot 25 is an arc-shaped sliding groove. The thickness of the groove is adapted to the thickness of the limiting block 22, so that the limiting block 22 can rotate smoothly along this arc-shaped groove and be locked into the groove end after rotating into place to achieve axial limiting. In specific implementation, when the connecting component 3 is connected, the limiting block 22 should be located at the end of the limiting slot 25 away from the through slot 24.

[0025] In addition, the connecting component 3 includes a first connecting block 31 fixedly connected to the tank body 1 and a second connecting block 32 fixedly connected to the cover plate 11. An insert block 33 is fixedly connected to the second connecting block 32. Two slots 34 adapted to the size of the insert block 33 are opened on the first connecting block 31. A locking block 35 is elastically connected to the insert block 33 by a spring 36. That is, there is a cavity inside the insert block 33, and the spring 36 is placed inside the cavity. The spring 36 presses against a locking block 35. The locking block 35 can partially protrude from the surface of the insert block 33 under the action of the spring 36. When the insert block 33 is inserted into the slot 34, the locking block 35 is pressed to retract it. After it is fully inserted, the locking block 35 will pop out under the action of the spring 36. In specific implementation, the distance between the locking block 35 and the second connecting block 32 should be the same as the thickness of the first connecting block 31, so that the locking block 35 can lock the cover plate 11 and the tank body 1 in the horizontal direction.

[0026] In practice, a directional sign 104 is provided in a prominent position on the outer wall of the tank 1. The directional sign 104 can be a graphic with an arrow mark, and its direction is consistent with the direction in which the cover plate 11 needs to be rotated to unlock the limiting component 2. This provides users with intuitive operation guidance and improves the convenience of operation when unlocking the tank 1.

[0027] Furthermore, the cover plate 11 is provided with an alignment groove 12 that matches the size of the tank body 1. A rubber gasket 14 is fixedly connected in the alignment groove 12. When the cover plate 11 is pressed down and rotated to lock by the limiting component 2, the opening of the tank body 1 will be tightly pressed into the alignment groove 12, and the rubber gasket 14 will undergo elastic deformation, thereby forming a reliable static seal between the cover plate 11 and the tank body 1.

[0028] In addition, the can 1 is provided with an inner liner 101, a buffer layer 102 and an outer shell 103 from the inside out. The inner liner 101 is made of polytetrafluoroethylene, the buffer layer 102 is made of silicone, and the outer shell 103 is made of aluminum alloy. That is to say, the innermost layer of the can 1 is the inner liner 101, which is in direct contact with corrosive liquids and is made of polytetrafluoroethylene, which has excellent corrosion resistance. The middle layer is the buffer layer 102, which is made of elastic silicone. Its main function is to absorb external impact energy and prevent the inner liner 101 from breaking. The outermost layer is the outer shell 103, which is made of high-strength and lightweight aluminum alloy, providing the main structural support and protection for the entire packaging can.

[0029] Working principle: When sealing the tank 1 is required, first align the limiting post 13 below the cover plate 11 with the opening of the tank 1. Then align the two limiting blocks 22 with the two through slots 24 on the limiting ring 23. Next, press down on the cover plate 11, and the limiting blocks 22 will descend vertically along the through slots 24 to the bottom. Then rotate the cover plate 11, causing the limiting blocks 22 to slide from the through slots 24 into the connected arc-shaped limiting grooves 25 until they reach the end of the limiting grooves 25. This process achieves vertical positioning of the cover plate 11 by constraining the limiting blocks 22 with the limiting ring 23. At the same time, the cover plate 11... The alignment groove 12 at the bottom and the rubber gasket 14 inside it are tightly pressed against the edge of the tank body 1 to form a preliminary seal. During rotation, pressing the locking block 35 causes the insert block 33 on the second connecting block 32 to be inserted into the corresponding slot 34 of the first connecting block 31. After the locking block 35 passes the slot 34, it automatically pops out, thereby completely locking the cover plate 11 to the tank body 1 in the horizontal direction, forming a double guarantee. When opening, the locking block 35 must be pressed first to release the horizontal locking of the connecting component 3, and then the cover plate 11 is rotated in the opposite direction to make the limiting block 22 return to the through groove 24, and then the cover plate 11 can be lifted upward.
