Drinking Bottle

During the Tang and Song dynasties in China, a blowpipe was introduced to produce hollow glass containers. This technique paved the way for the development of the modern drinking bottle industry, which emerged between 1904 and 1908. Following this, in the 1950s, China established several large-scale modern bottle factories. Notably, the 1980s witnessed a significant advancement in glass bottle production: the introduction of lightweight glass bottles. This breakthrough not only conserved raw materials and fuel but also enhanced production efficiency, reduced transportation costs.

Drinking bottles come in many different shapes and sizes, so there are several ways to classify them. One method is to look at their overall shape, such as whether they are round, have handles, or are square. They can hold anywhere from 1 milliliter to 25 liters of liquid. Another way to classify bottles is by the shape of their bottom, which can be round, oval, square, rectangular, or flat. Round bottles are the most common. You can also look at the size of the bottle mouth, which can be wide, small, or a spray nozzle. Wide-mouth bottles are used for semi-fluid or solid items, while small-mouth bottles are for liquids.
The way the bottle mouth and cap fit together is also important. There are many different types of matching forms, such as continuous thread, cork, pour, crown cap, rolling cap, plastic cap, spraying, pressure-twist open, side-sealing pry open, glass stopper frosted, and tube bottle mouths. The dimensions and tolerances of bottle caps are standardized so that they fit securely on the bottle. Depending on their use, some bottles are used only once while others can be recycled many times.
Finally, bottles are classified by their forming method. They can be molded or controlled, which means they are manufactured in different ways. Knowing how to classify drinking bottles can help you choose the right one for your needs, whether you are storing liquids or solids, or recycling them.

The type of glass used for drinking bottles can affect the production process and the appearance of the final product. Mold bottles are formed directly in the mold using liquid glass, while control bottles are created by molding processed glass tubes. The color of glass bottles can vary from colorless to opaque, with most recycled glass bottles being clear for optimal content visibility. However, green and brown bottles are often used for beverages and medicine respectively due to their ability to absorb ultraviolet light and protect their contents. In some cases, such as with cosmetics and ointments, opacified glass bottles may be used. It is important to consider the wall thickness when using colored glass, with a suggested maximum thickness of 10% for certain wavelengths of light.
