Types and Measurement of Cosmetic Bottles and Packaging

I. Types of Cosmetic Bottles and Packaging

 

Vacuum Bottles: Composed of a cap, shoulder sleeve, vacuum pump, and piston. They rely on air pressure for use. The dispensers come with different types of nozzles, including a pointed nozzle (some are all plastic, while others have an outer layer of electroplated aluminum) and a flat duckbill nozzle (with an outer plastic layer).

 

Lotion Bottles: Consist of a cap, shoulder sleeve, lotion pump, and piston. Many have an internal tube. The external material is often acrylic, while the internal is made of PP. The caps are made from external acrylic and internal ABS.

 

Perfume Bottles: a. Internal components can be glass with an aluminum exterior (depending on whether the cap is twist or non-twist). b. PP bottles (small dropper bottles are all PP). c. Glass dropper bottles. d. Perfume bottles can have a glass or PP interior. Large capacities typically use glass due to longer storage times, while PP is suitable for small capacity and short-term storage. PCTA and PETG are mostly not used for perfume.

 

Cream Jars: These include an outer cap, inner cap, outer bottle, and inner container. They are made from four material combinations:

 

a. Outer acrylic, inner PP material. The caps consist of outer acrylic and an inner layer of ABS with a PP gasket.

b. Ceramic interior, with an outer layer of electroplated aluminum, and caps with an outer layer of electroplated aluminum and an inner layer of PP with a PP gasket.

c. Full PP jars with an inner PP gasket.

d. Outer ABS and inner PP with a PP gasket.

 

Blow-Molded Bottles: The main material is often PET, and the caps come in three varieties: snap cap, flip cap, and screw cap. Blow-molded bottles are directly molded, and they feature a raised point on the bottom, which appears shiny under light.

 

Injection Blow Bottles: Mainly made from PP or PE, with caps available in snap cap, flip cap, and screw cap versions. Injection blow bottles combine the processes of injection molding and blow molding into one, requiring only one mold. They have a bonded line on the bottom.

 

Aluminum-Plastic Tubes: These tubes consist of a PE interior and an exterior layer of aluminum with printing. They are categorized into round tubes, flat tubes, and oval tubes. Price ranking: round tubes < oval tubes < flat tubes.

 

All-Plastic Tubes: These tubes are entirely made from PE and are printed, silk-screened, and hot-stamped after being extruded. They are also available in round, flat, and oval shapes. Price ranking: round tubes < oval tubes < flat tubes.

 

II. Nozzles, Lotion Pumps, Soap Dispensers, and Length Measurements

 

Nozzles: They can be snap-on (half aluminum or full aluminum), with plastic threads, and some have an aluminum cover or electroplated aluminum on top.

 

Lotion Pumps: Available in vacuum and dip tube types, both with threaded closures. The large cover and head cap can also have an aluminum cover or electroplated aluminum. The dispensers come in pointed and duckbill nozzles.

 

Soap Dispensers: These have a larger diameter and use threaded closures. The large cover and head cap can also have an aluminum cover. Some have thread steps, while others have a left-right screw mechanism.

 

Length Measurement: Includes dip tube length (from the gasket to the end of the tube or FBOG length), exposed length, and the length measured from the bottom of the large cover to the opening (equal to the length from the bottle shoulder to the bottom).

 

Standard categorization: Primarily based on the product's inner diameter (inner diameter is the diameter of the end inside the pump) or the height of the large collar.

 

Nozzles: 15/18/20 MM, all-plastic also available in 18/20/24.
Lotion Pumps: 18/20/24 MM.
Soap Dispensers: 24/28/32(33) MM.
Large Collar Height: 400/410/415 (purely standard designations, not actual heights).

 

Note: Standard categorization is represented as follows:
Lotion Pumps: 24/415.

 

Measurement methods include skinless measurement and volumetric measurement, with errors within 0.02g. Pump size can also be used to differentiate measurements.
