A few days ago, a can-making enterprise in Huairou successfully developed a 5-liter iron beer barrel, which has obtained national patents and achieved mass production. This R&D result has changed the status quo of imports of such packaging, filling Asia’s gap in this technology area.
The 5 litre beer barrel is a large-capacity beer packaging container made of tinplate. The middle part of the top cover is equipped with a vent valve, which can balance the pressure difference between the inside and outside of the barrel when taking the wine. The bottom of the can body is equipped with an opening valve, and the wine liquid is extracted through two actions of pulling out and rotating, and the sealed state of the container can be restored through the rotation of the opening valve.
This iron beer barrel can keep the beer fresh for a long time in an oxygen-free state, preserves the flavor and quality of the beer, and has a large barrel capacity, strong sealing, safety and health, convenient carrying, novel packaging forms, and breaks the tradition. Cans and glass bottles dominate the stalemate in the Chinese beer market. It is understood that, at present, large-capacity beer barrel shape, vent valve, opening valve have obtained national patents, and a large number of production, thus changing the status quo of our country's packaging rely on imports.
