Description

Technical Field

[0001] This utility model relates to the field of carbonate packaging technology, and specifically to a carbonate packaging leak-proof device. Background Technology

[0002] Carbonate packaging typically refers to packaging made of polycarbonate materials. Polycarbonate is a high molecular polymer containing carbonate groups in its molecular chain, and mainly includes products such as water cups, buckets, tableware, and food containers.

[0003] In the prior art, packaging made of carbonate includes storage barrels. The storage barrels are transparent and rigid. The storage barrels store liquid materials. The top of the storage barrel is equipped with a barrel lid. A sealing gasket is adhered and connected inside the barrel lid. When the barrel lid and the top of the storage barrel are threaded together, the sealing gasket and the top of the storage barrel abut against each other, thereby achieving the effect of preventing leakage of the storage barrel.

[0004] However, when the storage container is used for a long time, the sealing gasket will age. Since the sealing gasket is stuck to the lid, it is time-consuming and laborious to replace the sealing gasket, resulting in poor performance of the storage container. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof device for carbonate packaging to solve the technical problem in the prior art where the sealing gasket ages when the storage container is used for a long time. Because the sealing gasket is stuck to the lid, it is time-consuming and laborious to replace the sealing gasket, resulting in poor performance of the storage container.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-7 As shown, a leak-proof device for carbonate packaging includes: a storage tank 1, a mounting plate 15, and a sealing gasket 16.

[0034] The storage tank 1 is threadedly connected to the top of a connecting pipe 4. The top of the connecting pipe 4 is fixedly connected to a tank cover 5. The bottom of the tank cover 5 has an installation groove 14. The mounting plate 15 is abutted against the inner wall of the installation groove 14. The top of the mounting plate 15 passes through the tank cover 5 and has several threaded holes 13 along the axis. The inner wall of the threaded holes 13 is threadedly connected to bolts 6. The top of the sealing gasket 16 is fixedly connected to the mounting plate 15 and abutted against the storage tank 1. When the storage tank 1 stores liquid materials, the user controls the tank cover 5 to rotate the connecting pipe 4, and the connecting pipe 4 is threadedly connected to the top of the storage tank 1. The sealing gasket 16 fixed to the tank cover 5 abuts against the storage tank 1, thereby achieving the effect of preventing leakage at the connection between the storage tank 1 and the tank cover 5.

[0035] When the storage tank 1 is used for a long time, the sealing gasket 16 will age. The user controls the bolt 6 to rotate, thereby releasing the threaded connection between the bolt 6 and the inner wall of the threaded hole 13. Then, the mounting plate 15 is removed from the mounting groove 14, and the mounting plate 15 with the sealing gasket 16 is removed from the tank cover 5. Then, the new mounting plate 15 is inserted into the mounting groove 14, and the new sealing gasket 16 is fixed to the tank cover 5 by the mounting plate 15. The bolt 6 is threaded into the threaded hole 13 to fix the mounting plate 15, thereby achieving the effect of easy replacement of the sealing gasket 16 and avoiding the inconvenience of replacing the sealing gasket 16 which is fixed to the tank cover 5 by adhesive.

[0036] In some specific embodiments, a protective component is fixedly connected to the outer edge of the top of the storage tank 1. A sealing groove 17 is provided on the top of the storage tank 1. The sealing gasket 16 is abutted against the inner wall of the sealing groove 17. When the lid 5 is installed on the top of the storage tank 1, the sealing gasket 16 is inserted into the sealing groove 17. The sealing gasket 16 and the inner wall of the sealing groove 17 abut against each other, thereby achieving the effect of sealing the connection between the lid 5 and the storage tank 1. The abutment between the sealing gasket 16 and the inner wall of the sealing groove 17 increases the effective path for sealing the connection. When the storage tank 1 is tilted, the protective component protects the storage tank 1 and prevents the storage tank 1 from breaking when it is hit, thereby preventing leakage.

[0037] In some specific embodiments, a threaded extrusion strip 18 is fixedly connected to the inner wall of the sealing groove 17. The extrusion strip 18 abuts against the sealing gasket 16. The extrusion strip 18 has a semi-circular cross-section. When the sealing gasket 16 is inserted into the sealing groove 17, the extrusion strip 18 fixed to the inner wall of the sealing groove 17 abuts against the sealing gasket 16. Since the bucket lid 5, carrying the sealing gasket 16, is inserted into the sealing groove 17 in a rotating direction, the extrusion strip 18 can squeeze the sealing gasket 16. The sealing gasket 16 deforms under the pressure, further ensuring that the gap between the sealing groove 17 and the sealing gasket 16 is sealed. The shape of the extrusion strip 18 avoids damage to the sealing gasket 16.

[0038] In some specific embodiments, the protective component includes a protective ring 2 and a protective pad 3. The protective ring 2 is fixedly connected to the outer edge of the top of the storage tank 1, and the protective pad 3 is fixedly connected to the side of the protective ring 2 away from the storage tank 1. The protective pad 3 has a semi-circular cross-section. When the storage tank 1 is tilted, the protective pad 3 comes into contact with the object that the storage tank 1 will contact when it is tilted. The protective pad 3 provides initial cushioning, and then the protective ring 2 provides secondary cushioning, thereby avoiding the phenomenon of collision between the storage tank 1 and the object. The shape of the protective pad 3 can ensure that the protective pad 3 can resist the object when the storage tank 1 is tilted at different angles.

[0039] In some specific embodiments, a buffer assembly is fixedly connected to the bottom of the bucket lid 5. The buffer assembly is disposed inside the storage bucket 1 and includes: a buffer tube 7, a spring 8, a buffer column 11, and a buffer plate 12. The top end of the buffer tube 7 is fixedly connected to the bucket lid 5, the buffer column 11 is slidably connected to the inner wall of the buffer tube 7, the bottom end of the buffer column 11 is fixedly connected to the buffer plate 12, and the buffer plate 12 is slidably connected to the inner wall of the storage bucket 1. The upper and lower ends of the spring 8 are fixedly connected to the bucket lid 5 and the buffer column 11, respectively. When the storage bucket 1 is tilted, the liquid material inside the storage bucket 1 rises upward due to its own inertia. The buffer assembly can block and buffer the liquid material, preventing it from directly impacting the sealing gasket 16 and thus affecting its service life. At the same time, it prevents the sealing gasket 16 from leaking due to excessive impact force from the liquid material. When the liquid material moves upward, the buffer plate 12 blocks it. The impact force of the liquid material drives the buffer plate 12 to move upward. The buffer plate 12, along with the buffer column 11, slides along the inner wall of the buffer tube 7. The buffer column 11 converts the impact force of the liquid material into elastic force through the compression spring 8, thereby achieving the effect of buffering the liquid material.

[0040] In some specific implementations, limiting grooves 9 are respectively opened on both sides of the inner wall of the buffer tube 7, and limiting plates 10 are respectively fixedly connected to the top two ends of the buffer column 11. The limiting plates 10 are slidably connected to the inner wall of the limiting grooves 9, and the limiting plates 10 are abutting against the inner wall of the limiting grooves 9. When the buffer column 11 slides along the inner wall of the buffer tube 7, the buffer column 11 carries the limiting plates 10 to slide along the inner wall of the limiting grooves 9. The abutting between the limiting plates 10 and the inner wall of the limiting grooves 9 provides a limiting effect for the buffer column 11, preventing the buffer column 11 from rotating. When the buffer plate 12 is no longer impacted by liquid material, the spring 8 abuts against the buffer column 11 and moves downward along the inner wall of the buffer tube 7. At this time, the bottom end of the limiting plate 10 abuts against the inner wall of the limiting grooves 9, thereby preventing the buffer column 11 from detaching from the buffer tube 7.

[0041] In some specific embodiments, the buffer plate 12 is disc-shaped, and the inner diameter of the buffer plate 12 gradually increases from top to bottom along the axis of the buffer column 11. When the liquid material impacts the buffer plate 12 upward, the shape of the buffer plate 12 can collect the liquid material in the center of the buffer plate 12. The impact force of the liquid material can be directly transmitted to the buffer column 11 through the buffer plate 12. At the same time, the shape of the buffer plate 12 achieves the effect of buffering the liquid material, avoiding the phenomenon of the liquid material directly impacting the side of the buffer plate 12 and causing impact damage to the buffer plate 12.

[0042] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
