The basic classification and packaging form of cosmetic glass bottles

Cosmetic glass bottles should have the characteristics of smooth and transparent, easy to disinfect, corrosion resistance, high temperature resistance, and good airtightness. There are many varieties of cosmetic glass bottles, from small bottles with a capacity of ml to large bottles of more than ten liters, from round shapes. There are many types of bottles, square, special-shaped to the handle, colorless transparent amber, green, blue, and black light-shielding bottles and opaque glass bottles, there are countless varieties. Regarding the basic classification of cosmetic glass bottles, the specific content is as follows: In terms of manufacturing process, cosmetic glass bottles are generally divided into two categories: molded bottles and controlled bottles. Molded bottles are divided into two types: large-mouth bottles (bottle mouth diameter of more than millimeters) and small-mouth bottles. The former is used to hold powder, block and paste-like objects, and the latter is used to hold liquids. , According to the form of the bottle mouth, it is divided into cork bottle mouth, screw bottle mouth, crown cap bottle mouth, rolling bottle mouth frosted bottle mouth, etc. According to the usage, it is divided into 'one-time bottles' that are discarded after use once and 'recycled bottles' that are used in multiple cycles. , According to the classification of the contents, it can be divided into acid bottles, medicine bottles, reagent bottles, infusion bottles, preparation bottles and so on. , Cosmetic glass bottles can be roughly divided into the following categories according to the different uses of medicines: packaging for infusion, packaging for oral liquid, packaging for tablets and capsules, and packaging for powder injections. Infusion packaging: The major domestic infusion packaging is mainly glass infusion bottles. There are generally two packaging forms for cosmetic glass bottles, one is ordinary packaging in corrugated boxes, the other is heat shrink packaging using PVC or PE film, and there are a small amount of pallet packaging, from the degree of protection of the product From the perspective of cleanliness requirements, the quality of heat-shrink packaging and pallet packaging is much better than ordinary carton packaging. Now it has developed into PE film heat-shrinked and put into the carton. It is clean and hygienic, and can be used for aseptic packaging. This is also the future The development direction of cosmetic glass bottles. Before packaging cosmetic glass bottles, there is generally a full inspection process called acceptance process. This process is divided into manual inspection and automatic inspection. At present, most domestic cosmetic glass bottles use manual inspection methods. Under the irradiation of the table, each bottle is visually inspected to eliminate unqualified products with appearance defects. Manual inspection is restricted by various conditions such as visual inspection and experience. The missed inspection rate is relatively high, and the labor intensity is also high. Automatic inspection , The size, appearance, defects, etc. of the bottle can be inspected, and the missed inspection rate is relatively low. It is also the development direction and effective way to improve the quality of cosmetic glass bottles.
