Description

Technical Field

[0001] This utility model relates to the field of plastic bucket technology, specifically to an easy-open square plastic bucket. Background Technology

[0002] Plastic drums, as a widely used container, play an important role in many fields due to their lightweight, durability, low cost, and ease of molding. Mainly made of polymer materials such as polyethylene and polypropylene, plastic drums possess good chemical stability, resisting the corrosive effects of various chemicals, and also have good sealing performance, making them suitable for storing liquids or solids. Compared to traditional round plastic drums, square plastic drums offer a greater advantage in space utilization due to their unique shape. The four corners of the square drum reduce gaps during packaging and transportation, thereby increasing loading capacity and reducing logistics costs. Furthermore, square plastic drums are more stable during storage and handling, less prone to rolling, and particularly suitable for warehousing environments.

[0003] Current square barrels typically have a sealing cap fitted over the top opening to ensure airtight packaging. A handle is then attached to the side of the barrel for easy transport. This simple structure causes instability when the barrel is carried by hand, as the handle can deform the barrel. Additionally, the sealing cap can easily detach from the barrel, resulting in inconsistent sealing.

[0004] In summary, there is a need for a square plastic bucket with a stable structure and seal that is easy to open. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an easy-open square plastic bucket, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An easy-open square plastic bucket includes a bucket body, which is a square bucket structure that is wider at the top and narrower at the bottom. A reinforcing frame and a sealing frame are fixedly fitted onto the outer wall of the bucket. The sealing frames are spaced apart at the top of the reinforcing frame. A fixing block is provided inside the reinforcing frame. One side of the fixing block is fixed to the outer wall of the bucket. Four fixing blocks are arranged in a cross shape along the outer wall of the square bucket. A bucket handle is connected across the outer wall of two opposite fixing blocks. A cap sealing assembly is fitted onto the top opening of the bucket body. The bottom of the cap sealing assembly is gapped at the top surface of the sealing frame.

[0008] The sealing assembly includes a bucket lid, an outer sealing frame, and an inner sealing frame. The bucket lid is fitted onto the top surface of the bucket body. The bottom surface of the bucket lid is fixed with the outer sealing frame and the inner sealing frame. The inner sealing frame is sleeved on the outer wall of the top surface of the bucket body and is located inside the outer sealing frame. A pull ring is integrally formed on one side of the outer sealing frame.

[0009] Furthermore, a tear strip is connected to one side of the pull ring. The tear strip is located inside the outer sealing frame. The side of the tear strip away from the pull ring is fixed to the inner wall of the outer sealing frame. A tear groove is provided on the inner wall of the outer sealing frame.

[0010] Furthermore, the break bar has an inverted U-shaped structure, with the bottom two ends of the inverted U-shaped structure of the break bar connected to the side wall of the pull ring and the inner wall of the outer sealing frame, respectively.

[0011] Furthermore, a second reinforcing rib is fixed to the outer wall of the bucket handle, a handle is fixed to the inner wall of the bucket handle, and adapter posts are fixed to the inner walls on both sides of the bucket handle, with the adapter posts rotatably connected to the inside of the fixing block.

[0012] Furthermore, an inner connecting block is inserted inside the fixing block, and a slot is opened on the top surface of the inner connecting block. The end of the adapter post away from the bucket handle is engaged inside the slot.

[0013] Furthermore, a first locking rib is fixed on one side of the inner connecting block, and a second locking rib is fixed on the other side of the inner connecting block. Both the first and second locking ribs are locked inside the fixed connecting block, and a pull groove is opened on the other side of the inner connecting block.

[0014] Furthermore, the top surface of the bucket lid is provided with a lid groove, and the bottom surface of the bucket lid is provided with a lid protrusion, which is inserted into the inside of the bucket body.

[0015] Furthermore, the cover groove is a square groove structure that fits into the bottom surface of the barrel.

[0016] Furthermore, the bottom surface of the barrel is a groove structure, and multiple first reinforcing ribs are fixed to the inner wall of the groove structure of the barrel.

[0017] Furthermore, the sides of the bottom surface inside the barrel have rounded corners.

[0018] This utility model provides an easy-open square plastic bucket. Compared with the prior art, it has the following advantages:

[0019] 1. By setting sealing frames and reinforcing frames on the outer wall of the barrel and connecting the barrel handle to the fixing blocks on the reinforcing frames, the structural strength of the barrel is improved;

[0020] 2. When sealing the lid on the top surface of the barrel, the inner sealing frame seals the top opening of the barrel, while the outer sealing frame blocks the top of the reinforcing frame, providing protection for the inner sealing frame. This prevents the lid from being accidentally opened during sealing, ensuring the safety of the barrel during sealing.

[0021] To open the bucket, simply pull the ring on the outer edge of the lid and lift it upwards to easily open the lid, ensuring ease of opening; it requires no effort or tools and can be opened by hand.

[0022] 3. By connecting the pull ring and the outer sealing frame with a break strip, the position of the pull ring inside the outer sealing frame can be guaranteed during sealing, which improves the stability of the pull ring. When pulling out the pull ring to open the lid, it is easy to put your hand inside the pull ring, and then simply pull the pull ring to break the break strip, thereby disconnecting the connection with the outer sealing frame. The opening operation is simple.

[0023] By pre-reserving a tear groove on the inner wall of the outer sealing frame, the outer sealing frame can be torn open together when the pull ring is pulled out, further improving the convenience of opening the lid;

[0024] 4. By setting an inverted U-shaped break strip, the break strip has a reserved bending length before the pull ring is broken from the outer sealing frame. This allows the pull ring to be pulled out from inside the outer sealing frame first, and then the pull ring can be pulled to break from the outer sealing frame without reserving a scissor cut. This improves the convenience of breaking the pull ring and tearing open the bucket lid.

[0025] 5. The inner connecting block can be pulled out by placing your hand inside the groove. Depending on the weight requirements, the inner connecting block and the bucket handle can be replaced with a higher strength material to ensure the strength of lifting the plastic bucket and improve the convenience of replacing the bucket handle.

[0026] 6. By adopting a square groove structure that allows the bucket to be inserted into the lid, the bucket can be inserted into the groove perfectly after the lid is opened, serving as the base of the bucket. This increases the support area at the bottom of the bucket and improves the stability of the bucket when it is placed after being opened.

[0027] 7. The sides of the bottom inside the bucket are rounded, which makes the transition between the inner side wall and the bottom of the bucket smoother and makes cleaning easier. Attached Figure Description

[0042] Example 1

[0043] To address the technical problems in the background section, the following easy-open square plastic bucket is provided:

[0044] Combination Figures 1-11As shown, the easy-open square plastic bucket provided by this utility model includes a bucket body 1. The bucket body 1 is a square bucket structure that is wider at the top and narrower at the bottom. A reinforcing frame 2 and a sealing frame 4 are fixedly fitted onto the outer wall of the bucket body 1. The sealing frame 4 is spaced apart on the top of the reinforcing frame 2. A fixing block 3 is provided inside the reinforcing frame 2. One side of the fixing block 3 is fixed to the outer wall of the bucket body 1. Four fixing blocks 3 are arranged in a cross shape along the outer wall of the square bucket body 1. A bucket handle 6 is connected across the outer walls of two opposite fixing blocks 3. A cap sealing component 5 is fitted onto the top opening of the bucket body 1. The bottom gap of the cap sealing component 5 is located on the top surface of the sealing frame 4.

[0045] The sealing assembly 5 includes a bucket lid 51, an outer sealing frame 52, and an inner sealing frame 53. The bucket lid 51 is fitted onto the top surface of the bucket body 1. The bottom surface of the bucket lid 51 is fixed with the outer sealing frame 52 and the inner sealing frame 53. The inner sealing frame 53 is sleeved on the outer wall of the top surface of the bucket body 1. The inner sealing frame 53 is located inside the outer sealing frame 52. A pull ring 521 is integrally formed inside one side of the outer sealing frame 52.

[0046] The following effects can be achieved based on the above structure:

[0047] 1. By setting a sealing frame 4 and a reinforcing frame 2 on the outer wall of the barrel body 1, and connecting the barrel handle 6 and the fixing block 3 on the reinforcing frame 2, the structural strength of the barrel body 1 is improved.

[0048] 2. When sealing the lid 51 on the top surface of the barrel body 1, the inner sealing frame 53 is used to seal the top opening of the barrel body 1, while the outer sealing frame 52 is sealed on the top of the reinforcing frame 2, which provides protection for the inner sealing frame 53. During sealing, the lid 51 will not be accidentally opened, ensuring the safety of the barrel body 1 during sealing. When opening the barrel body 1, simply pull the pull ring 521 on the outer sealing frame 52 and lift it upward to easily open the lid 51, ensuring the convenience of opening the barrel body 1.

[0049] In this embodiment, a tear strip 522 is connected to one side of the pull ring 521. The tear strip 522 is disposed inside the outer sealing frame 52. The side of the tear strip 522 away from the pull ring 521 is fixed to the inner wall of the outer sealing frame 52. A tear groove 523 is provided on the inner wall of the outer sealing frame 52.

[0050] By connecting the pull ring 521 and the outer sealing frame 52 with the break strip 522, the position of the pull ring 521 inside the outer sealing frame 52 can be guaranteed during sealing, which improves the stability of the pull ring 521. When pulling out the pull ring 521 to open the lid 51, simply pull the pull ring 521 to break the break strip 522, thereby disconnecting the connection with the outer sealing frame 52, making the opening operation simple.

[0051] By pre-reserving a tear groove 523 on the inner wall of the outer sealing frame 52, the outer sealing frame 52 can be torn open together when the pull ring 521 is pulled out, which further improves the convenience of opening the bucket lid 51.

[0052] In this embodiment, the breakable bar 522 has an inverted U-shaped structure. The two ends of the bottom of the inverted U-shaped structure of the breakable bar 522 are respectively connected to the side wall of the pull ring 521 and the inner wall of the outer sealing frame 52. By setting the breakable bar 522 with an inverted U-shaped structure, the bending length reserved by the breakable bar 522 before the pull ring 521 is disconnected from the outer sealing frame 52 allows the pull ring 521 to be pulled out from the inside of the outer sealing frame 52 first, and then the pull ring 521 can be pulled to disconnect from the outer sealing frame 52, thereby improving the convenience of the pull ring 521 breaking operation.

[0053] Example 2

[0054] like Figures 3-10 As shown, based on the above embodiments, this embodiment further provides the following:

[0055] The outer wall of the bucket handle 6 is fixed with a second reinforcing rib 62, the inner wall of the bucket handle 6 is fixed with a grip 61, and both sides of the inner wall of the bucket handle 6 are fixed with adapter posts 63, which are rotatably connected to the inside of the fixing block 3.

[0056] In this embodiment, an inner connecting block 31 is inserted inside the fixing block 3. A slot 311 is opened on the top surface of the inner connecting block 31, and the end of the adapter post 63 away from the bucket handle 6 is engaged inside the slot 311. By connecting the adapter post 63 of the bucket handle 6 inside the fixing block 3, the connection strength between the bucket handle 6 and the bucket body 1 is ensured. At the same time, the adapter post 63 is further engaged inside the fixing block 3 by the inner connecting block 31, thereby further improving the connection strength of the bucket handle 6.

[0057] In this embodiment, a first locking rib 312 is fixed on one side of the inner connecting block 31, and a second locking rib 313 is fixed on the other side of the inner connecting block 31. Both the first locking rib 312 and the second locking rib 313 are locked inside the fixed connecting block 3. A pull groove 314 is provided on the other side of the inner connecting block 31. When the inner connecting block 31 is inserted into the fixed connecting block 3, the first locking rib 312 and the second locking rib 313 are used to lock it into the fixed connecting block 3, ensuring the stability of the inner connecting block 31. Then, the inner connecting block 31 can be pulled out by placing a hand inside the pull groove 314, which improves the convenience of replacing the bucket handle 6.

[0058] In this embodiment, the top surface of the bucket lid 51 is provided with a lid groove 511, and the bottom surface of the bucket lid 51 is provided with a lid protrusion 512, which is inserted into the inside of the bucket body 1. By providing the lid groove 511 and lid protrusion 512 structure, when the bucket lid 51 is sealed on the top surface of the bucket body 1, the lid protrusion 512 is inserted into the inside of the bucket body 1, ensuring the airtightness of the plastic bucket.

[0059] In this embodiment, the cover groove 511 is a square groove structure that fits into the bottom surface of the barrel 1. By adopting a square groove structure that the barrel 1 can be inserted into the cover groove 511, the barrel 1 can be inserted into the cover groove 511 after the cover 51 is opened, serving as the base of the barrel 1. This increases the support area at the bottom of the barrel 1 and improves the stability of the barrel 1 when it is opened.

[0060] In this embodiment, the bottom surface of the barrel 1 is a groove structure, and a plurality of first reinforcing ribs 11 are fixed on the inner wall of the groove structure of the barrel 1.

[0061] In this embodiment, the side of the inner bottom surface of the bucket body 1 is rounded; the rounded corner structure of the side of the inner bottom surface of the bucket body 1 makes the transition between the inner side wall and the bottom surface of the bucket body 1 smoother, making the cleaning operation more convenient.

[0062] Working principle and usage process of this utility model:

[0063] First press Figures 1-11 After placing the items to be sealed into the barrel 1, fasten the lid 51 to the opening at the top of the barrel 1. Insert the lid protrusion 512 into the inside of the barrel 1 to seal it. The inner sealing frame 53 is fitted onto the outer wall of the barrel 1. At this time, there is a gap between the bottom surface of the outer sealing frame 52 and the top surface of the sealing frame 4 that is not large enough for a finger to be inserted, thus completing the sealing of the barrel 1. In the sealed state, the sealing point between the lid 51 and the barrel 1 is protected by the outer sealing frame 52 and the sealing frame 4, ensuring the stability of the sealing of the barrel 1. Then, you can hold the barrel handle 6 to transfer the sealed plastic barrel. If the weight of the barrel 1 after being filled is large, you can first pull out the inner connecting block 31 to release the lock on the barrel handle 6, and then replace it with a barrel handle 6 made of metal with higher structural strength.

[0064] When it is necessary to open the barrel 1, simply pull the pull ring 521 from the inside of the outer sealing frame 52. The tear strip 522 will be stretched first, causing the pull ring 521 to be pulled out from the inside of the outer sealing frame 52. Then, continue to pull the pull ring 521 to break the tear strip 522, causing one side of the pull ring 521 to separate from the outer sealing frame 52. Continue to pull the pull ring 521 to tear the outer sealing frame 52 along the tear groove 523, tearing the outer sealing frame 52 into an upper and lower part, and completely separating the pull ring 521 and the lower part of the outer sealing frame 52 from the upper part of the outer sealing frame 52, thereby increasing the gap between the outer sealing frame 52 and the sealing frame 4, and then making it convenient to open the barrel lid 51 by hand.

[0065] Finally, after opening the lid 51, place the lid 51 on the ground as a base, and insert the bucket body 1 into the lid slot 511 to improve the stability of the bucket body 1 after it is opened.
