1. Precise quantitative output
Controllable dosage: The design of the pump head (such as piston structure) can achieve a fixed output volume (such as 0.2mL, 0.5mL, etc.) per single press to avoid waste.
Strong consistency: The amount of product output per press is stable, suitable for high-value or precise dosage products (such as essence, sunscreen).
2. Sealing and preservation
Anti-reflux design: The built-in one-way valve prevents liquid reflux and avoids contamination of the remaining product in the bottle.
Isolate air: The pump head and the bottle body fit tightly to reduce the contact between the contents and the air and extend the shelf life (especially for easily oxidized ingredients such as vitamin C).
3. Easy to use
One-handed operation: Press to take, no need to pour or dip, suitable for lotions and creams with poor fluidity.
Lock design: Some pump heads are equipped with a rotating lock (such as a 90° rotation lock) to prevent accidental pressure leakage during transportation or carrying.
4. Adaptability and diversity
Various materials: The pump body is mostly PP (polypropylene) or PE (polyethylene), which is corrosion-resistant; the spring and steel ball may be stainless steel.
Flexible specifications: The spring force or pump port diameter can be adjusted according to the viscosity (for example, thick lotions require a larger pump port or increased spring elasticity).
Appearance customization: The nozzle can be matched with electroplating, matte and other processes to match the brand design.
5. Safety and hygiene
Anti-disassembly design: Some products use a non-detachable structure to prevent secondary filling or adulteration.
Low residue: The internal structure of the pump body is optimized to reduce residue and improve product utilization.
6. Special function expansion
Foam pump: Convert liquid into foam through a mesh filter element (such as cleansing mousse).
Vacuum pump: Use the principle of air pressure to completely squeeze out the product in the bottle (such as high-end essence packaging).
Strawless design: Directly squeeze through the pump body for use, suitable for high-viscosity products.
7. Environmental trend
Replaceable: Supports replacement core design to reduce packaging waste.
Recyclable materials: Some brands use bio-based plastics or PCR (post-consumer recycled) materials.
Application scenarios
Skin care products: lotions, essences, sunscreens, etc.
Personal care: shower gel, hand soap, shampoo (low viscosity).
Medical field: topical drug lotion.
