28mm 4CC Output Custom Colored PP Plastic Crown Emulsion Pump Lotion Pump Hand Wash Screw-in

Excellent choice! A 4cc lotion pump is a specific and very common size in the world of packaging. "4cc" refers to the dosage volume—it dispenses approximately 4 milliliters (ml) of product per full pump stroke.

Key Characteristics of a 4cc Lotion Pump

• Dose Volume: ~4.0 ml per pump. This is considered a medium-to-large dose, ideal for products where a substantial amount is needed per application.

• Typical Viscosity: Designed for medium-viscosity products like lotions, creams, shower gels, thicker serums, and some liquid soaps. It has wider flow paths than a 1cc or 2cc pump to handle thicker formulas.

• Neck Finish: The most common bottle neck finish for a 4cc pump is 28-410. This means:

  • 28mm is the outer diameter of the bottle's neck thread.

  • 410 refers to the specific thread profile and cap/pump skirt design.

• Construction: Standard components: PP/PE plastic body, stainless steel spring, and a rubber or PE gasket for sealing.

  

  

  Common Applications (Why Choose 4cc?)

  This pump is chosen when the desired single-use amount is larger:

  Body Lotions & Creams: To cover an arm or leg

  Shower Gels & Bath Gels: For a full body wash.

  Shampoos & Conditioners: Especially for thick, moisturizing formulas

  Sunscreens (Body): To ensure adequate coverage for sun protection

  Hand Soaps: For institutional or family-sized containers where a larger dose is standard.

  Household Cleaners: Like dish soaps or all-purpose cleaners.

  In summary, a 4cc lotion pump is the workhorse for body care and thicker liquid products, offering a practical, hygienic, and user-friendly dispensing solution with a substantial, single-dose volume. Always ensure it's compatible with your specific product and bottle.
