Description

Technical Field

[0001] This utility model provides an environmentally friendly sealing cap structure for a paint baking bucket, belonging to the field of packaging container technology. Background Technology

[0002] As an industrial coating widely used in automobiles, furniture, machinery, and other fields, the packaging, storage, and transportation of paint are crucial. Paint cans are the most commonly used packaging containers. Currently, the sealing cap structures for paint cans on the market are mainly divided into two types: one is a press-fit sealing cap, usually made of metal or plastic, which is forcibly pressed into the can opening by external force, relying on the interference fit between the cap and the can opening to achieve a seal; the other is a structure that uses bolts or clips for locking.

[0003] Existing lids for paint cans can generally meet normal usage needs. However, these lids rely primarily on a single sealing structure. During transportation or handling, if the can is tilted or impacted, a momentary gap may form between the lid and the can opening, causing a small amount of paint to leak out, contaminating the can and the environment. Furthermore, they lack auxiliary protection and have poor sealing performance. Therefore, this invention provides an environmentally friendly sealing lid structure for paint cans. Utility Model Content

[0004] The technical problem solved by this utility model is that the bucket lid mainly relies on a single sealing structure, lacks auxiliary protection, and has poor sealing performance. During transportation or handling, if the bucket is tilted or impacted, a small amount of paint may seep out.

[0005] To solve the technical problem, the technical solution provided by this utility model is: a sealing cap structure for an environmentally friendly paint baking bucket, comprising:

[0006] A bucket lid, wherein the top of the bucket lid is recessed and a sealing groove is provided along the periphery of the inner top wall of the bucket lid;

[0007] A sealing gasket, embedded in a sealing groove, is used to form an elastic seal with the opening of the paint can;

[0008] The bottom of the bucket lid is provided with a surrounding curtain along the periphery, which is placed outside the sealing groove, and the outer side of the curtain is covered with a silicone rubber band;

[0009] Locking assembly for removably and securely sealing the lid to the opening of the paint can.

[0010] Furthermore, the locking assembly includes an annular locking ring and a lever-type handle hinged to the locking ring.

[0011] Furthermore, the outer surface of the bucket lid is coated with a low-VOC water-based paint coating.

[0012] Furthermore, the outer wall of the curtain is provided with limiting protrusions placed on both sides of the silicone rubber band.

[0013] Furthermore, the curtain is shaped like a trumpet and is made of silicone material.

[0014] Furthermore, the sealing gasket includes an inner layer that comes into contact with the chemicals inside the paint can, and an outer layer that forms a primary compression seal with the can lid and the can opening. The inner layer is made of chemically resistant EPDM material, and the outer layer is made of thermoplastic TPE material.

[0015] The beneficial effects of this utility model are:

[0016] This invention forms a first primary seal through sealing gaskets and locking components, which can effectively isolate the internal and external environments. At the same time, the curtain located on the outside of the lid, under the tension of the silicone rubber band, tightly adheres to the outer wall of the paint can, forming a second auxiliary seal. This can effectively prevent the intrusion of external pollutants such as dust and rainwater, and provide additional leak-proof protection in the event of accidental tipping of the paint can. The double seal provides excellent performance. Attached Figure Description

[0022] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly mentioned in this specification are defined relative to their structure and are relative concepts. Therefore, they may vary depending on their location and usage; thus, these or other directional terms should not be interpreted as restrictive terms.

[0023] The singular forms “a,” “the,” and “the” used in this specification are intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0024] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] According to the appendix Figure 1 , 2 As shown in Figure 3: This utility model provides an environmentally friendly sealing cap structure for a paint can, including: a can lid 1, the top of which is recessed, the outer surface of which is coated with a low-VOC water-based paint coating, and a sealing groove 2 along the periphery of the inner top wall of the can lid 1; and a sealing gasket 3, which is embedded in the sealing groove 2 and used to form an elastic seal with the mouth of the paint can. The sealing gasket 3 includes an inner layer that comes into contact with the chemicals inside the paint can and an outer layer that forms a main compression seal with the can lid 1 and the mouth of the paint can. The inner layer is made of chemically resistant EPDM material, and the outer layer is made of thermoplastic TPE material. Specifically, the can lid 1 body can be made of a material with a thickness of 0. The 5-1.0mm galvanized steel sheet is stamped to ensure sufficient mechanical strength. Its top is designed with a concave shape. This structure not only increases the overall rigidity of the lid and prevents it from deforming under pressure, but also facilitates the stacking of paint buckets, saving storage space. The low-VOC water-based paint coating uses water as the dispersion medium, which greatly reduces the use of organic solvents and reduces environmental pollution at the source. When the lid 1 is pressed, the TPE outer layer of the double-layer sealing ring 3 can produce a large elastic deformation, which fits tightly with the inner wall of the sealing groove 2 of the lid and the rolled edge of the paint bucket, forming a reliable airtight and liquid-tight barrier.

[0026] As per the instruction manual Figure 1 , 2 As shown in Figure 4: The bottom of the bucket lid 1 has a surrounding curtain 4 along the periphery, placed outside the sealing groove 2. The outer side of the curtain 4 is fitted with a silicone rubber band 5. The outer wall of the curtain 4 is provided with limiting protrusions 9 on both sides of the silicone rubber band 5. The curtain 4 is shaped like a trumpet. The curtain 4 is made of silicone material. Specifically, the silicone material has excellent weather resistance, elasticity and chemical stability. The limiting protrusions 9 form a groove to stably fix the silicone rubber band 5 in it, so that the curtain 4 bound by the silicone rubber band 5 can better cover and fit the outer wall of the upper part of the bucket opening after being covered by the paint bucket.

[0027] As per the instruction manual Figure 2 , 4As shown: Locking assembly 6 is used to detachably and securely seal the lid 1 to the mouth of the paint bucket. Locking assembly 6 includes a ring-shaped locking ring 7 and a lever handle 8 hinged to the locking ring 7. Specifically, through the lever principle, a large locking force can be generated with a small force. When the lever handle 8 is pulled down, the circumference of the locking ring 7 can be tightened, thereby applying a uniform axial pressure to the lid 1, compressing the sealing gasket 3 to achieve an airtight seal.

[0028] The principle of this utility model

[0029] When sealing the paint can, first place the can lid 1 with the sealing gasket 3 on the mouth of the paint can. Then, put the silicone rubber band 5 between the limiting protrusions 9 on the curtain 4. Under the action of the silicone rubber band 5, the curtain 4 is tightly attached to the body of the can, forming an auxiliary seal. Then, put the locking component 6, which is in the open state, on the edge of the can lid and the rolled edge of the can mouth, ensuring that the inner side of the locking ring 7 is properly engaged with the two. Finally, press down the lever handle 8 until it is completely closed and locked. During this process, the locking ring 7 tightens, firmly fixing the can lid 1, and the sealing gasket 3 is compressed to form the main seal.

[0030] In summary, this utility model forms a first primary seal through the sealing gasket 3 and locking assembly 6, which can effectively isolate the internal and external environments. At the same time, the curtain 4 located on the outside of the lid is tightly attached to the outer wall of the paint can under the tension of the silicone rubber band 5, forming a second auxiliary seal, which can effectively prevent the intrusion of external pollutants such as dust and rainwater, and provide additional leak protection in the event of accidental tipping of the paint can. The double seal has excellent performance, the entire sealing process is fast and reliable, requires no auxiliary tools, and is easy to operate.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
