The use characteristic and types of glass bottle
Glass bottle is the main container of food, medicine and chemical industry. They have good chemical stability, easy to seal, good air tightness, transparency, and can be observed from the outside; good storage performance; smooth surface, easy to disinfect and sterilize; beautiful appearance, rich decoration; a certain mechanical strength, can withstand the pressure in the bottle and the external force in the transport process; Wide distribution of materials, low price and other advantages. Its shortcomings are high quality (mass-capacity ratio), brittleness and fragility. However, with the new technology of thin-walled lightweight and physicochemical toughening, these shortcomings have been significantly improved, so the production of glass bottles can increase year by year under the fierce competition with plastics, iron hearing and iron cans.
There are many kinds of glass bottles, ranging from small bottles with 1ML capacity to large bottles with dozens of liters, from round, square, shaped and handle bottles, from colorless and transparent amber, green, blue, black shading bottles and opaque opaque glass bottles, etc. As far as manufacturing technology is concerned, glass bottles are generally divided into two categories: moulding bottles (using model bottles) and control bottles (using glass bottles). Molded bottles can be divided into two categories: large-mouth bottles (with a diameter of more than 30MM) and small-mouth bottles. The former is used to hold powdery, massive and pasty articles, while the latter is used to hold liquids. According to the form of bottle mouth, it can be divided into cork bottle mouth, thread bottle mouth, crown cap bottle mouth, rolled bottle mouth grinding bottle mouth, etc. According to the usage situation, it can be divided into "one-time bottle" which is discarded once and "recycling bottle" which is used many times. According to the classification of containers, it can be divided into wine bottles, beverage bottles, oil bottles, canned bottles, acid bottles, medicine bottles, reagent bottles, infusion bottles, cosmetic bottles and so on.
