Description

Technical Field

[0001] This application relates to the field of paint bucket technology, and in particular to a recyclable paint bucket. Background Technology

[0002] As the primary packaging for paint, the design of paint cans directly affects the paint's preservation efficiency and ease of use. Currently, small-capacity paint cans are commonly used in the market for small-scale applications (such as home repairs, model painting, and partial renovations), but these products still have some issues in use.

[0003] Traditional bucket lids often use simple threaded caps or snap-on plastic caps, lacking a secondary sealing structure. During long-term storage, micro-gaps can easily form at the joint between the lid and the bucket body due to thermal expansion and contraction or mechanical deformation, causing volatile organic compounds to continuously escape, polluting the air and accelerating paint curing, resulting in poor performance or even unusability for subsequent uses.

[0004] Patent application CN202022652028.7 discloses a paint bucket, including a bucket body, a lid, and a locking device. The locking device includes a ring-shaped clamp, a first transmission block, and a second transmission block. One part of the clamp is broken, and one end of the first and second transmission blocks are respectively hinged to the two ends of the broken clamp. The other end of the second transmission block is hinged to the middle of the first transmission block. The clamp simultaneously secures the outer edges of both the bucket body and the lid. While this paint bucket design strengthens the fit between the bucket body and lid, micro-gaps may still appear when the bucket body and lid deform, leading to seal failure.

[0005] Therefore, there is an urgent need to develop a paint storage container with an efficient sealing design. Utility Model Content

[0006] To improve the sealing effect of paint buckets, this application provides a reusable paint bucket.

[0007] The reusable paint bucket provided in this application adopts the following technical solution: A reusable paint bucket includes a bucket body, a bucket lid, a rubber ring, and a clamping device. The bucket body has a flange at its opening, the bucket lid is located on the flange, and the edge of the bucket lid has a groove that matches the flange, the groove engaging with the flange. The rubber ring surrounds the circumference of the bucket lid and is positioned at the joint between the bucket lid and the bucket body. The clamping device is located around the rubber ring and includes a first clamp and a second clamp, the first and second clamps being used to tighten the rubber ring. The first and second clamps are located on the upper and lower sides of the joint between the bucket lid and the bucket body, respectively.

[0008] By adopting the above technical solution, the groove and flange on the edge of the lid interlock to form the first physical seal, the rubber ring seals the joint between the lid and the body to form the second flexible seal, and the clamping device tightens the rubber ring to ensure that the rubber ring is tightly attached to the joint. This can prevent the seal from failing due to deformation of the body or lid, reduce the continuous escape of volatile organic compounds from the barrel and the oxidation and agglomeration of the contents, and extend the cycle life.

[0009] Optionally, the bucket lid includes a bucket lid body, the bucket lid body includes a center plate and a fixing ring around the center plate, the fixing ring includes an inner ring and an outer ring, the inner wall of the bucket body has a concave surface, the inner ring abuts against the concave surface; the outer ring is convex and has a groove at the bottom, which engages with the flange.

[0010] By adopting the above technical solution, the inner and outer rings of the fixing ring work together. The inner ring fits tightly against the inner wall of the flange to prevent paint from leaking out from the joint between the lid and the body. The outer ring is locked externally through a fastening mechanism to ensure that the lid can remain stably fitted after multiple openings and closings, thus maintaining a stable sealing effect.

[0011] Optionally, the barrel body is provided with a fixing groove on its outer periphery, and the barrel cover includes a barrel cover body and an extension plate provided at the edge of the barrel cover body. The extension plate is provided in the fixing groove, and the inner wall of the extension plate is provided with a protruding ring that corresponds to and cooperates with the fixing groove.

[0012] By adopting the above technical solution, the fixing groove and the convex ring cooperate to restrict the longitudinal loosening of the lid through mechanical locking, ensuring that the lid and the barrel body are always tightly fitted, and avoiding sealing failure caused by mechanical vibration.

[0013] Optionally, the first hoop is located on the periphery of the convex ring.

[0014] By adopting the above technical solution, the first hoop surrounds the circumference of the convex ring and applies radial pressure to the convex ring, forcing the convex ring to fit tightly against the inner wall of the fixing groove, which can prevent the convex ring from loosening or falling out of the fixing groove under external impact.

[0015] Optionally, the edge of the extension plate is concave, forming a convex ring on the inner side of the bucket lid and a limiting groove on the outer side, with the first hoop disposed in the limiting groove.

[0016] By adopting the above technical solution, the limiting groove provides a clear installation position for the first hoop, and the physical restriction of the groove wall prevents the first hoop from lateral displacement, ensuring that the first hoop is always in the preset unknown, thereby stably applying radial pressure.

[0017] Optionally, a stepped portion is provided on the inner side of the rubber ring, and the stepped portion is located at the joint between the bucket lid and the bucket body and abuts against the edge of the bucket lid.

[0018] By adopting the above technical solution, the stepped part on the inner side of the rubber ring is embedded in the joint between the bucket lid and the bucket body and abuts against the edge of the bucket lid. This can effectively fill the tiny gaps at the joint caused by external impact and avoid sealing failure caused by local gaps.

[0019] Optionally, the rubber ring has two grooves on its outer side, with the first and second rings respectively located in two different grooves.

[0020] By adopting the above technical solution, the two grooves on the outer side of the rubber ring provide a clear embedding position for the first and second hoops, ensuring that the hoops act precisely on the rubber ring and transmit a uniform clamping force to the circumference of the rubber ring.

[0021] Optionally, a reinforcing ring is provided around the circumference of the barrel.

[0022] By adopting the above technical solution, the reinforcement rings are evenly distributed along the circumference of the barrel, forming a "skeleton-like" support structure, which can distribute the load and reduce the micro-displacement caused by the deformation of the barrel at the joints.

[0023] Optionally, the bucket lid is provided with a paint inlet and a paint outlet; both the paint inlet and the paint outlet are provided with external threads and are equipped with a sealing cap, the inner wall of the sealing cap is provided with an internal thread that matches the external threads, and the bottom of the sealing cap is provided with a rubber plug, which is used to seal the paint inlet / paint outlet tightly.

[0024] By adopting the above technical solution, paint inlet and outlet are set up for precise pouring and touch-up of paint. The threads and rubber stoppers form an efficient seal, avoiding the introduction of impurities by frequently opening and closing the lid, while reducing paint exposure and extending the paint's service life.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. Through the synergistic action of the rubber ring and clamp device, the precise engagement of the groove and flange of the barrel lid forms a multi-level sealing barrier. The rubber ring can compensate for gaps through elasticity, reduce sealing failure caused by deformation of the barrel body or barrel lid, and extend the cycle life. 2. The tight fit between the fixing ring and the flange of the lid, as well as the engagement between the fixing groove and the convex ring on the extension plate, disperses mechanical stress and enhances the overall structural strength through the reinforcing ring around the barrel body, thus preventing sealing failure caused by deformation. 3. Through the stepped part and groove design on the outer side of the rubber ring, combined with the first and second hoop rings placed in the upper and lower hoop rings respectively, it can be ensured that the hoop rings act accurately on the rubber ring and transmit uniform clamping force to the circumference of the rubber ring.

[0026] 4. The threads and rubber plugs at the paint inlet and outlet form a highly efficient seal, ensuring airtightness at the opening and extending the cycle life. Attached Figure Description
