Why is the point design of amber pill bottles concave?

Have you noticed a difficult point, we often use amber pill bottles, health care glass bottles or other glass bottles at the bottom is not flat, just concave, what is the reason? Here's the secret behind it all!

First of all, the precipitation in the amber pill bottles after long-term storage, or fire will appear more precipitation, including melanin, tannins and tartar crystallization, etc., in order to convenient extracted precipitation, the shape of the bottle is designed to be concave type, and then promote the rising precipitation gathered in the bottom of the pit, pour the precipitation is concave type slowly slide into the bottle at the bottom of the shoulder, Avoid sediment at the bottom of the bottle. So be careful not to shake it, and leave a little bit on the shoulder of the bottle.

Second, the concave design also prevents the bottle from exploding, because it makes the bottom as strong as the curved wall. Moreover, the glass bottle is upside down during fermentation, so the precipitation caused by fermentation accumulates on the cap. The concave shape promotes the glass bottle to stand upright on the short board, providing balance.

In the past, amber pill bottles were blown out and therefore looped. Today's glass bottles are made by machines. The stronger, straight glass bottles are made by standing on an iron rod, so there is a hollow at the bottom. It is the reason why amber medicine bottles are concave at the bottom. 

The aluminum-plastic bottle stopper is a kind of medical bottle stopper, which is suitable for injection bottle and injection needle bottle. Current application in amber pill glass bottles: a low borosilicate glass production with aluminum cap composition. Aluminum-plastic bottle stopper is an important part of food and beverage packaging, which is the area where consumers first touch goods.

Lu: su stopper has kept content without product enclosed characteristics, but also has electronic security doors open and the effect of safety performance, so the application of common on bottled goods, thus aluminum bottle stopper for the food industry, beverage, industrial production, biological medicine on middle and lower reaches of the whole industry chain, is particularly important is the bottle container to pack the goods, The early development of aluminum-plastic bottle stopper is the use of cork raw materials, tinplate yellow cap and open cover, so far continued to develop the aluminum long-neck cap, carbonated beverage aluminum cap, hot add aluminum cap, injection aluminum cap, drug cap, open ring cap, safety factor claw cap and plastic aluminum bottle stopper and other commodities.
