Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic packaging barrels, and in particular to a crack-resistant plastic packaging barrel. Background Technology
[0002] Packaging drums are a general term in the packaging industry referring to various types of barrel-shaped packaging containers. Currently, packaging drums can be used to hold all sorts of different items. Plastic packaging drums have an even wider range of applications and can be used for various liquids and powdery or granular items.
[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: In the existing technology, most packaging barrels are designed as one piece. Due to their large size, they take up a lot of space when not in use. In addition, most packaging barrels are designed as a single plastic barrel. During use, prolonged exposure to sunlight will accelerate the aging of the barrel wall, making the barrel easy to break after impact.
[0004] Therefore, those skilled in the art have provided a crack-resistant plastic packaging drum to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crack-resistant plastic packaging bucket that can reduce the space occupied when not in use and improve the bucket's UV resistance and impact resistance of vulnerable parts during use.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A crack-resistant plastic packaging bucket includes an outer bucket, the outer wall of which is provided with a protective mechanism, the protective mechanism including a support layer, the outer wall of which is fixedly provided with a protective layer, and an inner bucket movably sleeved on the inner wall of the outer bucket; Both the upper end of the inner wall of the outer barrel and the upper end of the inner wall of the inner barrel are movably provided with hoop plates, and multiple rivets are threaded through the inner walls of both hoop plates. A waterproof cloth cover is fixedly provided at the lower end of the inner wall of the outer barrel.
[0007] Furthermore, the support layer is fixedly disposed at the lower end of the outer wall of the outer barrel, and the support layer is configured as an iron wire mesh structure.
[0008] Furthermore, the protective layer is made of PVC material, and an anti-ultraviolet coating is provided on the outer side of the protective layer.
[0009] Furthermore, the waterproof cover is fixedly connected to the inner wall of the outer tub and the inner tub by two hoops at its upper and lower ends, respectively. The waterproof cover is made of food-grade TPU fabric, and the two ends of the waterproof cover are connected to the inner tub and the outer tub by waterproof sealant.
[0010] Furthermore, both the outer and inner drums are made of HDPE material, and both the outer and inner drums contain a UV stabilizer mixed inside the raw materials.
[0011] Furthermore, a groove is provided at the lower end of the inner wall of the outer barrel, and the upper end of the outer wall of the inner barrel is slidably disposed in the groove, with an interference fit between the outer wall of the inner barrel and the groove.
[0012] Furthermore, a raised ring is provided on the upper end of the outer wall of the outer barrel, and a barrel lid is threadedly fitted onto the outer wall of the raised ring.
[0013] This utility model has the following beneficial effects: 1. The present invention proposes a crack-resistant plastic packaging barrel, which uses two hoops to press and fix the two ends of the waterproof cloth cover to the upper end of the inner wall of the outer barrel and the upper end of the inner wall of the inner barrel, respectively. Then, multiple rivets are inserted through the waterproof cloth cover and the two hoops and embedded in the inner wall of the inner barrel and the inner wall of the outer barrel. At this time, pulling the outer barrel up and down can adjust the overall height of the packaging barrel, and the waterproof cloth cover can prevent liquid from leaking out along the connection between the inner barrel and the outer barrel.
[0014] 2. The crack-resistant plastic packaging barrel proposed in this utility model has the following characteristics: the outer barrel diameter is larger than the inner barrel, so the outer barrel is more susceptible to impact. The protective layer can play a basic protective role, and the support layer can improve the overall strength of the protective layer. The combination of the two can achieve better impact resistance and slow down the aging rate of the outer barrel wall, avoiding the problem of easy cracking due to the decrease in overall strength after aging.

[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] Reference Figures 1 to 4 One embodiment provided by this utility model: A crack-resistant plastic packaging barrel includes an outer barrel 1, a protective mechanism 2 provided on the outer wall of the outer barrel 1, the protective mechanism 2 includes a support layer 201, a protective layer 202 fixedly provided on the outer wall of the support layer 201, and an inner barrel 3 movably sleeved on the inner wall of the outer barrel 1. Both the upper end of the inner wall of the outer tub 1 and the upper end of the inner wall of the inner tub 3 are movably provided with hoop plates 6, and multiple rivets 5 are threaded through the inner walls of both hoop plates 6. A waterproof cloth cover 4 is fixedly provided at the lower end of the inner wall of the outer tub 1.
[0019] Specifically, the sliding fit between the outer barrel 1 and the inner barrel 3 allows for easy adjustment of the overall height of the packaging barrel, thereby reducing the floor space occupied when the packaging barrel is not in use. Since the diameter of the outer barrel 1 is larger than that of the inner barrel 3, the outer barrel 1 is more susceptible to impact. The protective mechanism 2 can improve the impact resistance of the outer barrel 1. The clamp plate 6 and the rivets 5 can press and fix the two ends of the waterproof cloth cover 4 to the inner wall of the inner barrel 3 and the inner wall of the outer barrel 1, respectively.
[0020] Reference Figure 3 , Figure 4 The support layer 201 is fixedly installed at the lower end of the outer wall of the outer barrel 1, and the support layer 201 is made of iron wire mesh structure.
[0021] Specifically, the support layer 201 of the wire mesh structure can support the protective layer 202. When subjected to impact, the elastic deformation of the support layer 201 itself can reduce the impact of the impact force on the outer barrel 1.
[0022] Reference Figure 3 , Figure 4 The protective layer 202 is made of PVC material, and the outer side of the protective layer 202 is provided with an anti-ultraviolet coating.
[0023] Specifically, due to the strong corrosion resistance and rigidity of PVC material itself, it can resist erosion during storage and provide a certain degree of impact resistance when bumped during daily use.
[0024] Reference Figure 3The waterproof cover 4 is fixedly connected to the inner wall of the outer barrel 1 and the inner wall of the inner barrel 3 respectively by two hoop plates 6 at the top and bottom ends. The waterproof cover 4 is made of food-grade TPU cloth, and the two ends of the waterproof cover 4 are connected to the inner barrel 3 and the outer barrel 1 respectively by waterproof sealant.
[0025] Specifically, the waterproof cover 4 is connected to the inner tub 3 and the outer tub 1 at both ends by two clamps 6, so that the waterproof cover 4 can prevent liquid from leaking out from the connection between the inner tub 3 and the outer tub 1.
[0026] Reference Figure 1 , Figure 3 Both the outer barrel 1 and the inner barrel 3 are made of HDPE material, and both the outer barrel 1 and the inner barrel 3 contain UV stabilizers mixed in their raw materials.
[0027] Specifically, HDPE does not contain plasticizers and is not easily reacted with its contents. It also has good toughness and is not easily broken. However, due to its poor UV resistance, UV stabilizers need to be added during the manufacturing process.
[0028] Reference Figure 1 , Figure 3 The lower end of the inner wall of the outer barrel 1 is provided with a sliding groove, and the upper end of the outer wall of the inner barrel 3 is slidably disposed in the sliding groove, with an interference fit between the outer wall of the inner barrel 3 and the sliding groove.
[0029] Specifically, the outer wall of the inner barrel 3 is slidably disposed within the slide groove and is interference-fitted with the slide groove, so it will not fall down after the outer barrel 1 is stretched upward, thus ensuring the normal use of the packaging barrel.
[0030] Reference Figure 1 The outer barrel 1 has a raised ring at the upper end of its outer wall, and a barrel cover is threaded onto the outer wall of the raised ring.
[0031] Specifically, the outer barrel 1 is sealed by the barrel lid. Since the barrel lid and barrel body are mature existing technologies, they will not be described or elaborated on in detail.
[0032] Working principle: Pulling the outer barrel 1 upwards stretches both the outer barrel 1 and the inner barrel 3. Due to the interference fit between the outer wall of the inner barrel 3 and the inner wall of the outer barrel 1, the outer barrel 1 will not fall after being stretched to its maximum distance. At the same time, the waterproof cover 4 gradually unfolds during the stretching process, covering the connection between the inner barrel 3 and the outer barrel 1, thus preventing liquid from leaking out along the connection between the inner barrel 3 and the outer barrel 1. This reduces the footprint of the packaging barrel when not in use. During use, since the diameter of the outer barrel 1 is larger than that of the inner barrel 3, the outer barrel 1 is more susceptible to impact. When the outer barrel 1 is hit, the protective layer 202 prevents sharp points from scratching the barrel body. Then, the support layer 201 undergoes elastic deformation upon impact, which buffers the impact force to a certain extent, thereby reducing the impact force on the outer barrel 1 itself and reducing the risk of the outer barrel 1 breaking upon impact.
[0033] 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.
