Glass bottles are commonly used in packaging products nowadays. When making glass bottles, a depression is usually designed in the bottom of the glass bottle. Do you know the reason?
1. The sediment in the glass bottle will precipitate after being stored for a long time. The bottom of the glass bottle should be concave, so that when it stands upright, the sediment can be focused on the bottom of the groove, which can effectively prevent the sediment at the bottom of the bottle from stirring up the liquid in the bottle.
2. A depression designed at the bottom of the glass bottle can effectively prevent the explosion of the glass bottle, because the depression can make the bottom as strong as the curved structure of the bottle wall.At the same time, the hollow in the bottom of the glass bottle will make it more stable.
3. In the past, most glass bottles were pushed out, so they were mostly round, while nowadays, glass bottles are made by machines.A depression in the bottom of the glass bottle is convenient for the machine to process the glass bottle.
