[0031] This application provides a lightweight, constrained stackable plastic bucket.

[0032] like Figure 1 and Figure 2 As shown, a lightweight, constrained stackable plastic bucket includes: a bucket body 1, which has a tetrahedral structure; a handle 2, located at the top of the bucket body 1; a bucket opening 3, located at the top of the bucket body 1, with the bucket opening 3 and the handle 2 spaced apart; a bucket lid 4, used to close the bucket opening 3; and a hollow connecting post 5, located in the middle of the bucket body 1, with one end of the hollow connecting post 5 connected to a first side of the bucket body 1 and the other end of the hollow connecting post 5 connected to a second side of the bucket body 1, the first side and the second side being arranged opposite to each other; the hollow connecting post 5 is used to support a single plastic bucket or connect multiple plastic buckets through a connector.

[0033] In this application, hollow connecting columns 5 are used to connect two opposite sides of the barrel body 1, thereby improving the deformation resistance of the barrel body 1. Furthermore, the design of the hollow connecting columns 5 allows for the use of columnar rods to pass through multiple parallel plastic barrels to constrain them. It also allows for the use of binding ropes to pass through two rows of plastic barrels to constrain them together. Each row has at least two plastic barrels, and the two rows can be arranged horizontally or vertically. A specific example is as follows: Two rows of plastic barrels, two barrels per row, are placed at the bottom layer. Binding ropes are used to sequentially pass through the hollow connecting columns 5 of the four plastic barrels to bind and constrain them together. Then, another four plastic barrels are bound together in the same way. These four plastic barrels are placed as a second layer above the four plastic barrels at the bottom layer. Binding ropes are used to bind the four plastic barrels on the same side of both layers together, and the four plastic barrels on the other side of both layers are bound together. In practical use, there is no limit to two plastic buckets per column, no limit to two columns per layer, and no limit to two layers. This application does not limit the specific constraint method, but only provides a convenient way to use binding ropes to constrain multiple plastic buckets.

[0034] In other embodiments, a support rod can be used to pass through the hollow connecting column 5 and then the support rod can be erected. This can be combined with the structure of the plastic bucket with the hollow connecting column 5 to quickly erect the plastic bucket.

[0035] The barrel body 1, handle 2, and barrel opening 3 are integrally blow-molded. A first plane is defined by a plane passing through the center of the hollow connecting column 5 along its length and perpendicular to the length direction of the hollow connecting column 5. The through-hole on the handle 2 for hand passage is perpendicular to the first plane, and the handle 2 is symmetrically arranged about the first plane. This structural design facilitates the blow molding of the barrel body 1, handle 2, and barrel opening 3. In this embodiment, except for the barrel lid 4, all components are integrally blow-molded; the barrel lid 4 can be injection-molded.

[0036] The hollow connecting column 5 and the side wall of the barrel 1 are rounded at the connecting edges. This improves the connection strength between the hollow connecting column 5 and the barrel 1 in the blow-molded plastic barrel and also facilitates the blow-molding process for the plastic barrel.

[0037] The hollow connecting column 5 has a circular cross-section parallel to the first plane. The circular hollow connecting column 5 is convenient for blow molding.

[0038] The hollow connecting post 5 has four axially evenly distributed limiting grooves 6 at its end edge, with the line connecting two opposing limiting grooves 6 parallel to the height of the bucket. The hollow connecting post 5 is used for the binding rope to pass through, and the limiting grooves 6 are used to accommodate the binding rope at the end of the hollow connecting post 5. After the binding rope is used to secure multiple plastic buckets, the binding rope is tightened in the limiting grooves 6, stabilizing the position of the binding rope and the plastic buckets and improving the constraint stability.

[0039] Regarding the specific design of the limiting groove 6: the bottom of the limiting groove 6 is arc-shaped. The arc-shaped bottoms of the four limiting grooves 6 on the same end of the hollow connecting column 5 gradually move away from each other from the inner wall to the outer side of the hollow connecting column 5, and the concave surfaces of the arc-shaped bottoms of the four limiting grooves 6 on the same end of the hollow connecting column 5 are arranged back-to-back. This improves the fit between the binding rope and the limiting groove 6, enhancing the restraint effect.

[0040] The bottom of the bucket body 1 is provided with a first receiving groove 7 for accommodating the handle 2 and a second receiving groove 8 for accommodating the bucket lid 4. This facilitates the stacking of plastic buckets and improves the stability of stacking plastic buckets.

[0041] The first receiving groove 7 and the handle 2 are shaped to match, and the second receiving groove 8 and the lid 4 are shaped to match. When the area on the bottom of the bucket body 1 outside the receiving groove range of the first receiving groove 7 and the receiving groove range of the lid 4 abuts against the area outside the receiving groove range of the top handle 2 and the lid 4 of the bucket body 1, the bottom of the handle 2 abuts against the bottom of the first receiving groove 7 and the top of the lid 4 abuts against the bottom of the second receiving groove 8. This increases the contact area between the upper and lower plastic buckets, further improving the stability of stacking plastic buckets.

[0042] In one embodiment, the top of the barrel body 12 is also provided with a cylindrical boss, and the handle 8 is located between the cylindrical boss and the barrel opening 3. An annular groove is provided on the outer periphery of the cylindrical boss, and an annular groove is also provided on the outer wall of the barrel opening 3. The annular groove on the barrel opening 3 is located outside the range after the barrel lid 4 is tightened. In this application, the design of the annular groove can utilize elastic rings or binding ropes to wrap around the cylindrical boss of one plastic barrel and the outer periphery of the barrel opening 3 of another plastic barrel, and arrange the elastic rings or binding ropes in the annular grooves. The tops of two adjacent plastic barrels can be connected and constrained by the elastic rings or binding ropes, which can improve the constraint effect on multiple plastic barrels.

[0043] like Figure 3 As shown, for the first receiving groove 7 and the second receiving groove 8, in one embodiment, the width of the handle 8 connecting the root of the barrel body is smaller than the diameter of the barrel opening 3 and the cylindrical boss. The first receiving groove 7 is elongated. There are two second receiving grooves 8 at the bottom of the barrel body. One second receiving groove 8 corresponds to the barrel opening and the barrel lid, and the other second receiving groove 8 corresponds to the cylindrical boss. Moreover, the two second receiving grooves 8 are connected to the first receiving groove 7. The first receiving groove 7 and the second receiving groove 8 are connected by a curved transition. The part of the second receiving groove 8 away from the first receiving groove 7 can penetrate through both sides of the barrel body 1.

[0044] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
