1. Classification of glass bottles
(1) According to the shape, there are bottles, cans, such as round, oval, square, rectangular, flat, and special-shaped bottles (other shapes). Among them, most are round.
(2) According to the size of the bottle mouth, there are wide mouth, small mouth, spray mouth and other bottles and cans. The inside diameter of the bottle is less than 30mm, which is called a small-mouth bottle, which is often used to hold various fluids. Bottle mouth larger than 30mm inside diameter, no shoulder or less shoulder is called a wide mouth bottle, often used to hold semi-fluid, powder or block solid objects.
(3) Molded bottles and control bottles are classified according to the molding method. Molded bottles are made by molding liquid glass directly in the mold; control bottles are made by first drawing glass liquid into glass tubes and then processing and forming (small capacity penicillin bottles, tablet bottles, etc.).
(4) According to the color of bottles and cans, there are colorless, colored and opacifying bottles and cans. Most glass jars are clear and colorless, keeping the contents in a normal image. Green usually contains drinks; brown is used for medicines or beer. They can absorb ultraviolet rays and are good for the quality of the contents. The United States stipulates that the average wall thickness of colored glass bottles and cans should make the transmittance of light waves with a wavelength of 290 ~ 450nm lower than 10%. A few bottles of cosmetics, creams and ointments are filled with opalescent glass bottles. In addition, there are colored glass bottles such as amber, light cyan, blue, red, and black.
(5) Beer bottles, liquor bottles, beverage bottles, cosmetic bottles, condiment bottles, tablet bottles, canned bottles, infusion bottles, and cultural and educational bottles are classified according to use.
(6) According to the requirements for the use of bottles and cans, there are single-use bottles and recycled bottles and cans. Bottles and cans are used once and then discarded. Recycled bottles and cans can be recycled multiple times and used in turn.
The above classification is not very strict, sometimes the same bottle can often be classified into several types, and according to the development of the function and use of glass bottles, the variety will increase. In order to facilitate the production arrangement, our company classifies general materials bottles, high white materials, crystal white materials bottles, brown materials bottles, green materials bottles, milky materials bottles, etc. according to the material color.
