Description

Technical Field

[0001] This utility model relates to the field of paint packaging technology, specifically an improved paint packaging barrel. Background Technology

[0002] Coatings are liquid or solid materials that are applied to the surface of an object to form a protective film under certain conditions, providing protection, decoration, or other special functions. Coatings can be classified according to their product form as: liquid coatings, powder coatings, and high-solids coatings. During the production and processing process, packaging drums are mainly used for the storage and transportation of coatings. Currently, plastic packaging drums are mainly used for packaging and transporting coatings during the production and processing process. Plastic packaging drums mainly consist of two parts: the drum body and the drum lid. The drum lid and the drum body are connected by threads to seal and protect the coating.

[0003] Existing paint packaging barrels are often single-layered shells, which are easily damaged by collisions during daily production and transportation. This can lead to paint leakage, material waste, and pollution of the transportation environment. If the paint is corrosive, it can cause serious damage to transportation equipment and surrounding items. Furthermore, existing paint packaging barrels are often contaminated by paint after use and are usually intended for single use, resulting in the barrels being discarded as a whole after use. This not only pollutes the environment but also wastes resources. Therefore, we propose an improved paint packaging barrel. Utility Model Content

[0004] The main objective of this invention is to provide an improved paint packaging bucket that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved paint packaging bucket, comprising a bucket body and a bucket lid, wherein a rim is fixedly connected to the top edge of the bucket body, and a first external thread is provided on the upper end of the surface of the rim; a first internal thread adapted to the first external thread is provided on the inner wall of the bucket lid, and the bucket lid is threadedly connected to the top of the bucket body through the mutual engagement of the first internal thread and the first external thread; the bucket body comprises an outer shell, an inner liner, and a side ring, wherein a second internal thread is provided on the bottom surface of the inner cavity of the outer shell, and a second external thread matching the second internal thread is provided on the bottom surface of the inner liner, and the inner liner is threadedly connected to the inner cavity of the outer shell through the second internal thread and the second external thread; a side ring is fixedly connected to the top edge of the inner liner, and the diameter of the side ring is the same as the inner diameter of the outer shell.

[0006] Preferably, the inner wall of the inner cavity of the bucket lid is provided with a storage hole, and a spring is detachably connected to the inner cavity of the storage hole, and a pressure plate is fixedly connected to the bottom end of the spring.

[0007] Preferably, the inner cavity of the bucket lid is detachably connected to a sealing plate, and the diameter of the sealing plate is the same as the diameter of the side ring.

[0008] Preferably, the top of the edging has locking holes on both sides, and a carrying rod can be detachably locked into the inner cavity of the locking hole.

[0009] Preferably, the surface of the barrel is provided with a label groove, and the label groove is made of transparent plastic.

[0010] Preferably, the top of the bucket lid has a groove.

[0011] Preferably, disassembly holes are provided at corresponding positions on both sides of the top of the inner liner.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes an outer shell, an inner liner, a second external thread, a second internal thread, and a side ring that work together. The inner liner is threaded to the second internal thread at the bottom of the outer shell via the second external thread on its bottom surface. The side ring at the top of the inner liner fits snugly against the inner wall of the outer shell, limiting the inner liner's position and creating a gap between them. When the container is accidentally impacted, the impact force is first applied to the outer shell. The gap between the outer shell and the inner liner acts as a buffer, preventing direct rigid contact and direct transmission of the impact force. Before reaching the inner liner, the impact force is partially absorbed and dispersed within this gap, significantly reducing the risk of damage to the inner liner. This effectively prevents material waste, environmental pollution, and damage to transportation equipment caused by paint leakage. Furthermore, during packaging, the sealing plate and inner liner effectively isolate the paint inside, preventing contamination of other parts of the container. After use, the inner liner can be quickly disassembled by rotating it counterclockwise. The outer shell and inner liner can then be sorted and recycled, reusing parts such as the outer shell, reducing material waste and lowering packaging costs. Attached Figure Description

[0019] 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.

[0020] Example

[0021] Please see Figure 1 - Figure 4 The diagram shows an improved paint packaging bucket, comprising a bucket body 1 and a bucket lid 3. A rim 2 is fixedly connected to the top edge of the bucket body 1. A first external thread 8 is formed on the upper surface of the rim 2. A first internal thread 15, matching the first external thread 8, is formed on the inner wall of the bucket lid 3. The bucket lid 3 is threadedly connected to the top of the bucket body 1 via the mutual engagement of the first internal thread 15 and the first external thread 8. The bucket body 1 includes an outer shell 101, an inner liner 102, and a side ring 103. A second internal thread 11 is formed on the bottom surface of the inner cavity of the outer shell 101. A second external thread 10, matching the second internal thread 11, is formed on the bottom surface of the inner liner 102. The inner liner 102 is threadedly connected to the outer shell 101 via the second internal thread 11 and the second external thread 10. 1. The inner cavity has a side ring 103 fixedly connected to the top edge of the inner liner 102, and the diameter of the side ring 103 is the same as the inner diameter of the outer shell 101. By setting a rim 2 at the top edge of the barrel body 1 and opening a first external thread 8, which cooperates with the first internal thread 15 on the inner wall of the barrel lid 3, a stable connection between the barrel lid 3 and the barrel body 1 is achieved. At the same time, the inner liner 102 is connected to the second internal thread 11 of the inner cavity of the outer shell 101 through a second external thread 10, and the diameter of the side ring 103 at the top of the inner liner 102 is the same as the inner diameter of the outer shell 101. This achieves a tight combination of the double-layer structure of the barrel body 1, which not only enhances the overall sturdiness of the packaging barrel, but also forms a buffer space between the outer shell 101 and the inner liner 102, effectively improving the impact resistance of the packaging barrel during transportation and storage, and better protecting the internal coating.

[0022] The inner wall of the inner cavity of the lid 3 has a storage hole 12. A spring 13 is detachably connected to the inner cavity of the storage hole 12. A pressure plate 14 is fixedly connected to the bottom end of the spring 13. A sealing plate 9 is detachably connected to the inner cavity of the lid 3, and the diameter of the sealing plate 9 is the same as the diameter of the side ring 103. When the lid 3 is closed, the elastic force generated by the spring 13 is transmitted to the sealing plate 9 through the pressure plate 14, so that the sealing plate 9 is pressed tightly against the side ring 103 of the inner liner 102, which greatly enhances the sealing performance between the lid 3 and the inner liner 102, effectively preventing paint leakage, drying and contamination by external impurities, and ensuring the quality stability of the paint during storage and transportation.

[0023] The top two sides of the edge 2 are provided with locking holes 4, and the inner cavity of the locking holes 4 can be detachably locked with a carrying rod 5. By opening locking holes 4 on both sides of the top of the edge 2 and making the inner cavity of the locking holes 4 detachably locked with a carrying rod 5, the carrying rod 5 can be flexibly installed according to actual needs when handling the packaging barrel, providing users with a convenient way to carry it, reducing the burden of handling, and improving the convenience and stability of the handling process.

[0024] The container body 1 has a label slot 6 made of transparent plastic, and the lid 3 has a groove 7 at its top. The label slot 6 made of transparent plastic on the surface of the container body 1 allows for convenient placement of product information labels for the paint, such as ingredients, instructions for use, and shelf life. The transparent material effectively protects the labels from wear and moisture, ensuring they remain clear and legible. The groove 7 at the top of the lid 3 allows for convenient placement of small tools, such as stirring rods or brushes, for easy access by the user when using the paint, improving operational convenience.

[0025] The inner liner 102 has disassembly holes at corresponding positions on both sides of its top end. By opening disassembly holes at corresponding positions on both sides of the top end of the inner liner 102, users can more easily hold tools or insert their hands directly during the recycling process, providing a point of leverage for rotating the inner liner 102 counterclockwise. This makes disassembling the inner liner 102 easier and more efficient, further improving the convenience of packaging barrel recycling.

[0026] It should be noted that this utility model is an improved paint packaging bucket. The second external thread 10 at the bottom of the inner liner 102 is aligned with the second internal thread 11 at the bottom of the inner cavity of the outer shell 101. The inner liner 102 is rotated clockwise to ensure a tight connection. At this time, the top edge ring 103 of the inner liner 102 is fitted and limited against the inner wall of the outer shell 101, forming a gap between the outer shell 101 and the inner liner 102. Paint is then slowly poured into the inner liner 102, and the sealing plate 9 is placed on the upper surface of the inner liner 102. Finally, the bucket lid 3 is threaded to the top of the bucket body 1 through the first external thread 8 and the first internal thread 15. After connection, the pressure plate 14 at the bottom is engaged by the spring 13. The inner liner 102 is tightly fitted to the sealing plate 9 to ensure a sealing effect. During transportation, when the barrel 1 is impacted, the impact force is first applied to the outer shell 101. Because the gap between the outer shell 101 and the inner liner 102 can buffer and disperse the impact force, it is prevented from being directly transmitted to the inner liner 102, reducing the risk of damage to the inner liner 102, preventing paint leakage, ensuring transportation safety, and avoiding damage to equipment and the environment. After the paint is used, the inner liner 102 is rotated counterclockwise to separate its threaded connection with the outer shell 101, and the inner liner 102 is quickly disassembled. Then, the outer shell 101 and the inner liner 102 are sorted and recycled, and the outer shell 101 and other parts are reused, reducing material waste and packaging costs.
