Problems solved by technology

[0002] At present, closed barrels are usually used as packaging containers for liquid products, and these packaging containers usually need to be treated as solid waste after one use. With the environmental protection requirements increasing year by year, the cost of solid waste treatment is getting higher and higher, resulting in higher usage costs. The higher the rate, the greater the pressure on environmental protection

Abstract

The invention discloses a lining bag for a mouth-closed barrel, and the lining bag for the mouth-closed barrel comprises a bag body, a nut piece and a screw plug. The replaceable lining bag used for the mouth-closed barrel is formed through combination of the bag body, the nut piece and the screw plug. The bag body is used for storing liquids; the nut piece is connected to the bag body, installed on the mouth-closed barrel and is firmly combined with the mouth-closed barrel; and the screw plug and the nut piece are used in a combined manner and play a bag mouth sealing function. The lining bag for the mouth-closed barrel is simple in structure and convenient to use, the use functions required by liquid products in transportation and storage are guaranteed, the original mouth-closed barrel can be used many times by replacing the lining bag of the mouth-closed barrel, and meanwhile the treatment cost of solid waste is lowered, and the environmental protection pressure is lowered.

Description

technical field [0001] The invention relates to a liner bag, in particular to a liner bag for a closed barrel. Background technique [0002] At present, closed barrels are usually used as packaging containers for liquid products, and these packaging containers usually need to be treated as solid waste after one use. With the environmental protection requirements increasing year by year, the cost of solid waste treatment is getting higher and higher, resulting in higher usage costs. The higher the rate, the greater the pressure on environmental protection. Contents of the invention [0003] The purpose of the present invention is to provide a liner bag for a closed barrel, which can realize seamless docking with the existing liquid packaging barrel. Specifically, it is an innovative use mode, which converts a disposable closed packaging barrel into a reusable packaging bracket, thereby increasing the value of the original closed packaging barrel and solving the problems ra...
