Abstract
Description
Technical Field
[0001] This application relates to the field of plastic bucket technology, and more particularly to a plastic bucket structure. Background Technology
[0002] In the packaging industry, plastic drums are widely used for the storage and transportation of various goods, including food, chemicals, and pharmaceuticals, due to their advantages such as low cost, light weight, and strong corrosion resistance. Currently, many plastic drums use a simple snap-fit connection between the drum and its lid. This method is indeed convenient for opening and closing, and can improve work efficiency to some extent.
[0003] However, in actual use, when it is necessary to open the lid, it is often necessary to use a tear strip to disconnect the clamping structure from the lid, thereby separating the lid from the bucket body. Once the tear strip is torn, the lid loses its original clamping structure, which means that the lid can no longer be stably connected to the bucket body.
[0004] If materials need to be taken out multiple times during use, the lid may fall off or become unstable after the first opening because it cannot be effectively reattached to the bucket. This reduces the number of times the plastic bucket can be reused.
[0005] Therefore, there is an urgent need for a plastic bucket structure that can be repeatedly opened and stably connected to solve the above-mentioned technical problems. Utility Model Content
[0006] To address the aforementioned technical problems, this application provides a plastic bucket structure that enables repeated opening and stable connection between the bucket lid and the bucket body, thereby improving the reusability of the plastic bucket.
[0007] This application provides a plastic bucket structure, including:
[0008] The barrel body and the barrel lid are provided with a first fastening structure on the outer wall of the barrel body and a second fastening structure on the inner wall of the barrel lid. The first fastening structure and the second fastening structure cooperate to connect the barrel lid to the barrel body.
[0009] The bucket lid is provided with a repeating fastening part and a single fastening part. A part of the second fastening structure is located on the repeating fastening part and another part is located on the single fastening part. A zigzag tear strip is provided between the repeating fastening part and the single fastening part. The zigzag tear strip is controlled to break in order to peel the single fastening part off the bucket lid.
[0010] Optionally, the number of repeating clamping parts is multiple, and the distance between any two adjacent repeating clamping parts is equal.
[0011] Optionally, the shape of the repeating pressing part is one of trapezoidal, square, elliptical, or semi-circular.
[0012] Optionally, the bucket lid is provided with an opening element, which is connected to the tortuous tear strip.
[0013] Optionally, the shape of the bucket lid can be one of a circle, an oval, or a square.
[0014] Optionally, the lid is provided with a first positioning element, and the body of the bucket is provided with a second positioning element. When the first positioning element abuts against the second positioning element, the oil nozzle on the lid is located on the vertical line of the handle on the body of the bucket. There are two connection points between the handle and the body of the bucket, and the vertical line is the center vertical line of the line connecting the two connection points.
[0015] Optionally, the first positioning element is an extension extending downward from the bucket lid, and the second positioning element is a recessed groove that matches the extension and is located on the skirt of the bucket body.
[0016] Optionally, the first positioning element is a positioning block located inside the lid, and the second positioning element is a blocking block located between the body and the skirt, the blocking block being used to abut against the positioning block.
[0017] Optionally, the positioning block is located below the first clamping structure.
[0018] Optionally, the shape of the blocking block is one of triangle, sector, or ellipse.
[0019] As can be seen from the above technical solutions, this application has the following effects:
[0020] This application utilizes a first clamping structure on the outer wall of the bucket body and a second clamping structure on the inner wall of the bucket lid to cooperate with each other. The bucket lid is provided with a repeat clamping part and a single clamping part. After the tortuous tear strip is broken, the bucket lid can achieve a repeat clamping connection with the bucket body by means of part of the second clamping structure in the repeat clamping part. This effectively solves the problem that the bucket lid cannot be stably reconnected after being opened in the prior art, meets the usage needs of frequently opening the bucket lid, and improves the reusability of plastic buckets.

[0035] This application provides a plastic bucket structure for enabling repeated opening and stable connection between the lid and the bucket body, thereby improving the reusability of the plastic bucket. The specific implementation process of this application is described below.
[0036] Please see Figures 1 to 7 The present application provides a plastic bucket structure, comprising:
[0037] The barrel body 01 and the barrel lid 02 are provided. The outer wall of the barrel body 01 has a first clamping structure 03, and the inner wall of the barrel lid 02 has a second clamping structure 04. The first clamping structure 03 and the second clamping structure 04 cooperate to connect the barrel lid 02 to the barrel body 01. The barrel lid 02 is provided with a repeating clamping part 05 and a single clamping part 06. A part of the second clamping structure 04 is located on the repeating clamping part 05, and another part is located on the single clamping part 06. A zigzag tear strip 07 is provided between the repeating clamping part 05 and the single clamping part 06. The zigzag tear strip 07 is controlled to break to peel the single clamping part 06 from the barrel lid 02.
[0038] The barrel body 01 is used to hold and store items. The barrel lid 02 covers the opening of the barrel body 01 to seal and protect the items inside the barrel. The outer wall of the barrel body 01 is designed with a first snap-fit structure 03, and the inner wall of the barrel lid 02 is provided with a second snap-fit structure 04. The second snap-fit structure 04 matches the first snap-fit structure 03 on the barrel body 01. When the barrel lid 02 is placed on the barrel body 01, the second snap-fit structure 04 on the inner wall of the barrel lid 02 will contact and snap with the first snap-fit structure 03 on the outer wall of the barrel body 01, thus firmly fixing the barrel lid 02 to the barrel body 01.
[0039] A portion of the bucket lid 02 (the side of the bucket lid 02) is a reusable snap-fit part 05, and another portion is a single-use snap-fit part 06. The single-use snap-fit part 06 is adjacent to the reusable snap-fit part 05 and they are in an upper and lower relationship. On the bucket lid 02, the reusable snap-fit part 05 is on top and the single-use snap-fit part 06 is on the bottom. The two are connected by a tortuous tear strip 07.
[0040] When it is necessary to open the lid 02, the user can apply external force to the zigzag tear strip 07, causing it to break along a predetermined path. After the zigzag tear strip 07 is completely broken, the single-clamping part 06 and the repeated-clamping part 05 separate. At this time, a portion of the second clamping structure 04 still exists inside the repeated-clamping part 05. This portion of the second clamping structure 04 is still connected to the first clamping structure 03. When it is necessary to open the lid, the repeated-clamping part 05 is pried open outward by external force, thereby separating the first clamping structure 03 from the second clamping structure 04 (the portion located on the repeated-clamping part 05), thus opening the lid.
[0041] When the lid needs to be closed again, since there is still a part of the second clamping structure 04 on the repeated clamping part 05, this part of the second clamping structure 04 cooperates with the first clamping structure 03, so that the lid 02 can be connected to the body 01 again.
[0042] In this embodiment, the first clamping structure 03 on the outer wall of the bucket body 01 and the second clamping structure 04 on the inner wall of the bucket lid 02 cooperate with each other. The bucket lid 02 is provided with a repeating clamping part 05 and a single clamping part 06. After the tortuous tear strip 07 is broken, the bucket lid 02 can achieve a repeating clamping connection with the bucket body 01 by means of part of the second clamping structure 04 in the repeating clamping part 05. This effectively solves the problem that the bucket lid 02 cannot be stably reconnected after being opened in the prior art, meets the usage requirements of frequently opening the bucket lid 02, and improves the reusability of the plastic bucket.
[0043] In an optional embodiment, there are multiple repeating fastening portions 05, and the distance between any two adjacent repeating fastening portions 05 is equal. The number of repeating fastening portions 05 can be multiple, such as 2, 3, 4, etc., and the specific number is not limited here, but is determined by what is actually feasible. For example, when there are 4 repeating fastening portions 05, the angle between adjacent repeating fastening portions 05 is 90 degrees.
[0044] Multiple repeating clamping parts 05 are evenly distributed on the inner wall of the lid 02, ensuring a larger contact area between the lid 02 and the barrel body 01, resulting in a tighter fit. The evenly distributed repeating clamping parts 05 make the lid 02 more stable after it is closed, and it is not easy for it to loosen or fall off due to external force or vibration during transportation.
[0045] In an optional embodiment, the shape of the repeating clamping part 05 is one of trapezoidal, square, elliptical, or semi-circular.
[0046] In an optional embodiment, the lid 02 is provided with an opening element 08, which is connected to the zigzag tear strip 07. In actual use, the user can use the opening element 08 to tear open the zigzag tear strip 07, thereby separating the repeating clamping part 05 from the single clamping part 06.
[0047] In one optional embodiment, the shape of the lid 02 is one of a circle, an oval, or a square. When the lid 02 is quadrilateral, a repeating fastening part 05 is provided on each side of the lid 02.
[0048] In an optional embodiment, a first positioning element is provided on the lid 02 and a second positioning element is provided on the body 01. When the first positioning element abuts against the second positioning element, the oil nozzle 10 on the lid 02 is located on the vertical line of the handle 09 on the body 01. There are two connection points between the handle 09 and the body 01, and the vertical line is the center vertical line of the line connecting the two connection points.
[0049] The first positioning component is located on the inner edge of the lid 02, and the second positioning component is located on the outer edge of the body 01. The second positioning component matches the first positioning component, and the line connecting the two connection points passes through the center (center) of the lid 02. A perpendicular line is drawn from the center of this line. When the first positioning component abuts against the second positioning component, the oil nozzle 10 is positioned on this perpendicular line. When the plastic bucket is lifted to pour out the material, the oil nozzle 10 is positioned at the lowest point of the pour, thus facilitating the pouring out of the material.
[0050] The handle 09 on the container body 01 is typically designed for easy handling. The handle 09 is attached to the skirt of the container body 01, and its two connection points (i.e., the points where the handle 09 is fixed to the container body 01) determine its balance position. The perpendicular bisector is the straight line passing through the midpoint of the line connecting these two connection points and perpendicular to this line. The nozzle 10 is precisely aligned with the perpendicular bisector of the handle 09, making pouring liquids easier and reducing operational difficulty and time.
[0051] In this optional embodiment, the first positioning element is an extension 11 extending downward from the lid 02, and the second positioning element is a recessed groove 12. The recessed groove 12 matches the extension 11 and is located on the skirt of the barrel body 01. The extension 11 is integrally formed with the lid 02, and the size of the extension 11 is smaller than that of the recessed groove 12, so that the extension 11 can be inserted into the recessed groove 12. To ensure that the nozzle 10 is on the vertical line, the extension 11 is kept inserted into the recessed groove 12 each time the lid 02 is connected to the barrel body 01. This ensures that the nozzle 10 is in a relatively low position when pouring materials, making it easier to pour, and also reduces the possibility of the lid 02 rotating, thus reducing the possibility of the nozzle 10 shifting position.
[0052] In this optional embodiment, the first positioning element is a positioning block 13, located inside the lid 02. The second positioning element is a blocking block 14, located between the body 01 and the skirt, which abuts against the positioning block 13. When the lid 02 and body 01 are fastened together, the lid 02 is rotatable. The blocking block 14 extends upward to a certain height but does not restrict the rotation of the lid 02. The positioning block 13 extends inward from the inner wall of the lid 02. When the lid 02 rotates, the blocking block 14 is located on the movement trajectory of the positioning block 13, restricting the movement of the positioning block 13 and thus restricting the rotation of the lid 02. When the positioning block 13 moves to contact the blocking block 14, the nozzle 10 is on the vertical axis.
[0053] In an optional embodiment, the positioning block 13 is located below the first clamping structure 03. The positioning block 13 is located on the repeating clamping portion 05 and below the first clamping portion. In this embodiment, the blocking block 14 does not restrict the connection between the first clamping structure 03 and the second clamping structure 04.
[0054] In an optional embodiment, the shape of the blocking block 14 is one of a triangle, a fan shape, or an ellipse.
[0055] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
