Spray bottles are mainly used in the pharmaceutical bottle, cosmetic container and chemical bottle packaging markets. Through spray nozzle control technology, the dosage can be well grasped. Environmental protection and practical spray bottle complete equipment: It consists of durable bottle body and replaceable bottle bottom. The new bottle-in-bottle technology replaces the traditional airless spray structure with airless extrusion technology, which includes independent but must be filled into the bottle manually.
Cosmetic containers are used as a form of water, and sprays are mainly used for emergency hydration. For example, in very dry environments (deserts or air-conditioned rooms), or when applying makeup on a regular basis, makeup artists can use sprays or spray on sponges for dyeing and loosening purposes.
The principle of the spray bottle is to form a high pressure system in the bottle, and the liquid in the high pressure drop bottle is ejected in the form of very fine water particles. Because these sprayed water particles are very similar in effect and shape to natural mist, this bottle is called a spray bottle.
There are usually two types of cosmetic plastic container production processes: one is an extrusion blow molding process, in which plastic raw materials are added to an extruder, melt-plasticized to extrude a molten blank, and then placed in a bottle mold for blow molding cool down. It is then removed from the mold to remove the edges of the scrap to obtain the finished product. This process is mainly used to produce polyethylene and polyvinyl chloride plastic bottles.
The other is: injection stretch blowing process, that is, the plastic raw material passes through the tube blank of the injection molding machine, and then is stretched into a bottle mold for injection molding and cooled to obtain the finished product. This process is mainly used to produce PET plastic bottles.
