Anti-leakage coating plastic barrel

Abstract

The invention discloses an anti-leakage coating plastic barrel, and belongs to the technical field of plastic barrels. Through combined arrangement of an anti-leakage inner cover, a sealing top cover and the plastic barrel, internal threads are adopted for the inner wall of the top of the plastic barrel, external threads are adopted for the anti-leakage inner cover, and the anti-leakage inner cover and the plastic barrel are firstly subjected to threaded rotation; the situation that the outer wall of the top of a traditional plastic barrel is screwed to the cover in a threaded mode is abandoned, so that the situation that when coating is poured, the coating is left on the threaded part, and screwing of the cover is affected can be avoided, the inner wall face of the tightly-rotated leakage-proof inner cover and the inner wall face of the plastic barrel are located on the same face, coating pouring is facilitated, secondary capping is conducted through the sealing top cover, and the sealing effect is good. The sealing performance of the plastic barrel can be guaranteed, air is prevented from entering the plastic barrel to cause paint caking, the paint can be prevented from flowing out when the barrel is poured on the ground by pouring materials through the arc-shaped material opening, meanwhile, the situation that too much paint is poured out at a time can be avoided, and when the barrel falls on the ground, due to the fact that the gravity center of the barrel deviates to the side away from the material opening after the barrel falls on the ground, the paint can be prevented from flowing out.

Description

technical field [0001] The invention belongs to the technical field of plastic barrels, in particular to an anti-leakage paint plastic barrel. Background technique [0002] Plastic packaging barrels have good characteristics. It is not fragile, rust-free, light in weight, etc., and has excellent oil resistance and strong corrosion resistance. It is mostly used in the packaging of dangerous goods that require heat preservation, moisture resistance, pressure resistance and corrosion resistance. Plastic packaging barrels are often used to hold paint packaging, but the existing plastic packaging barrels have the following shortcomings to be improved: [0003] (1) The existing plastic bucket is composed of a barrel body and a top cover, and the barrel body and the top cover are threaded. When pouring paint, the paint is poured from the edge of the barrel along the barrel wall. Because the paint has fluidity , the paint will not stop flowing immediately, it will cause the paint ...

AI Technical Summary

Problems solved by technology

[0003] (1) The existing plastic bucket is composed of a barrel body and a top cover, and the barrel body and the top cover are threaded. When pouring paint, the paint is poured from the edge of the barrel along the barrel wall. Because the paint has fluidity , the paint will not stop flowing immediately, it will cause the paint to hang on the edge of the barrel until it drips on the outer edge of the barrel, because the top of the barrel is threaded, this will cause the paint to fall on the thread, which will affect the top cover and the barrel cover combine;

[0004] (2) The traditional plastic barrel has a large opening. When the plastic barrel is dumped on the ground, and the opening is large, it is easy to cause most of the paint to leak on the ground
