28/410 28/400 trigger sprayer plastic bottle foam trigger sprayer wholesale OEM sprayer

Common Materials

• Polypropylene (PP): Used for the rigid housing, trigger lever, and closure. Chosen for its chemical resistance and durability.

• Low-Density Polyethylene (LDPE): Used for the dip tube and gaskets. It's flexible and chemically resistant.

• Acetal (POM): Sometimes used for high-performance internal components like the piston and spring housing due to its low friction and high strength.

Compatibility: The Most Important Consideration

When sourcing a 28mm trigger sprayer, you must ensure it matches your bottle's neck finish.

• How to Check: Measure the outer diameter of the threaded neck of your bottle. It should be approximately 28 millimeters.

• Thread Pattern: The pitch and depth of the threads must also match. The standard designation "28/410" is the most reliable way to ensure compatibility.

• Gasket Seal: The sprayer must form a tight seal against the landing ring of the bottle's neck to prevent leaking.

  

  

  Advantages and Disadvantages

  Advantages:

  • Controlled Dispensing: Delivers a precise, measurable amount with each pull, reducing waste.

  • User-Friendly: The trigger mechanism is intuitive and requires less force than a finger pump.

  • Versatility: The ability to switch between mist and stream makes it suitable for various tasks.

  • Good Seal: Prevents leaks and evaporation when not in use.

  Disadvantages:

  • Not for Viscous Liquids: Struggles with very thick products like lotions or oils, which can clog the mechanism.

  • Mechanical Complexity: Has more moving parts than a simple cap, which can wear out or break.

  • Cost: More expensive than basic closures like screw caps or flip-tops.

  Summary

  The plastic trigger sprayer is an indispensable dispensing solution for watery to medium-viscosity liquids where controlled, targeted application is key. Its design is a perfect balance of functionality, cost-effectiveness, and user convenience, making it a staple in industries from household cleaning to personal care. When selecting one, the most critical factors are neck finish compatibility and chemical compatibility with the product being dispensed.
