Vacuum press bottle is a common cosmetic packaging, and its design principle mainly utilizes the principle of vacuum negative pressure to maintain the freshness and effectiveness of the product.
1. Structure of vacuum press bottle
A vacuum press bottle typically consists of a cylindrical or elliptical container and a piston placed at the bottom. These containers are usually made of plastic or glass to ensure the safety of the product.
2. Working principle of vacuum press bottle
The working principle of vacuum press bottles involves the following key components:
Pistons: The function of pistons is to prevent air from entering the bottle, creating a vacuum state. It is usually made of elastic materials so that it can move up and down when needed.
Spring: The function of a spring is to provide the necessary contraction force to maintain the position of the piston inside the bottle.
Atmospheric pressure: Atmospheric pressure is used to push the piston forward, allowing the product to be squeezed out of the bottle.
3. Advantages of Vacuum Pressing Bottles
The main advantage of a vacuum press bottle is that it can effectively isolate the product from contact with the outside world, thereby avoiding oxidation, deterioration, or bacterial growth of the product due to contact with air. This packaging technology can greatly extend the shelf life of products and ensure their freshness and effectiveness.
The vacuum press bottle also has precise dosage control function, which can adjust the dosage as needed. This not only helps to reduce waste, but also meets the needs of different consumers.
