Description

Plastic bucket that sealing performance is strong Technical Field The utility model relates to the technical field of plastic barrels, in particular to a plastic barrel with strong sealing performance. Background The plastic barrel is mainly used for storing and transporting various liquids, has good characteristics for special dangerous goods packaging, has the characteristics of uneasiness, rust resistance, light weight and the like, is good in oil resistance and strong corrosion resistance, is mainly used for dangerous goods packaging needing heat preservation, moisture resistance, pressure resistance and corrosion resistance, is mainly formed by blow molding, injection molding, plastic suction molding and rotational molding of polyethylene, polypropylene, polyester and other plastics, and is mainly used for containing liquid and solid objects in the industries of chemical industry, pesticide industry, food industry, hardware electronics industry, electromechanical industry and the like. The existing plastic bucket is poor in sealing performance, particularly when liquid is contained, leakage is easy to occur, waste of materials is caused, and the plastic bucket is inconvenient to use. For example, chinese patent publication No. CN214494066U discloses a sealed plastic barrel, which comprises a barrel body, the outside face of the open end of the barrel body is provided with a sealing ring and a first convex ring from top to bottom along the height of the outside face, the middle upper part of one side of the sealing ring away from the open end of the barrel body is provided with a cambered surface to the open end of the barrel body, the cambered surface is provided with a convex arc, the bottom end face of the sealing ring is provided with a positioning ring, the inside face of the open end of the barrel cover is provided with a clamping ring groove matched with the first convex ring, the inside bottom of the barrel cover is provided with a sealing ring groove clamped with the sealing ring, when the barrel cover is covered with the barrel body, the inside surface of the sealing ring groove is attached to the outside surface of the sealing ring, and the sealed plastic barrel has higher sealing performance, and liquid filled into the barrel body can not leak and burglary-proof effects.
