Everyone has noticed such a problem. The bottoms of the medicinal glass bottles, health care product glass bottles or other glass bottles that people often use are not flat, but recessed inward. How can this be done? What’s the matter, for the manufacturer of medical equipment glass bottles-Jiangsu Linlang Glass Products Co., Ltd., let’s look at this little-known secret!
First, the precipitate in the medicinal glass bottle has been stored for a long time, and some precipitates will appear, including melanin, tannic acid and its tartar crystals. In order to facilitate the separation of the sedimentation, the shape of the bottle bottom is designed as a concave shape, which promotes the precipitation to gather at the bottom of the concave shape when standing, and the sediment is slowly slipped from the bottom of the concave shape to the shoulder of the bottle to prevent sedimentation of the bottom of the bottle. Blowing makes muddy. Therefore, be careful when pouring, not shaking, and leave a little on the shoulder of the bottle after pouring.
Secondly, that design can also prevent the bottle from exploding, because the dent makes the bottom of the bottle as strong as the curved wall of the bottle. Also, the glass bottle was placed upside down when the alcohol was mellowed, so the precipitation caused by the mellow was accumulated on the stopper of the bottle. The dent makes the glass bottle stand firmly on the neck of the bottle and has a balanced effect.
In the past, medicinal glass bottles were blown out, so they were all circular. Today, all glass bottles are made by equipment. This kind of stronger straight glass bottle is made by standing on an iron stick, so there is a recess at the bottom, the iron stick is called the top and bottom rod. It is the reason why the bottom end is concave.
