Choosing the right dispenser for your project is a critical step in creating beautiful and effective packaging. You’ll need to consider the viscosity of your formula, the amount to be dispensed, and the surface you’re applying it to.
Chemical compatibility between your formula and metal or plastic components should also be considered when selecting a dispenser.
Anatomy of a Pump
Pumps work by creating a high-pressure zone above the product and low-pressure zone inside the dispensing chamber. This draws the product up the dip tube and through the nozzle.
A small steel or plastic ball prevents the product from draining back out of the pump.
A locking collar can prevent your pump from being actuated accidentally.
Airless Pump Bottles
Airless pump bottles work by creating a low-pressure zone or vacuum above your product. This low pressure causes the piston to ascend pushing your product through the dispenser where it can be applied.
Key Benefit: Airless pumps prevent your formula from being exposed to air and potentially oxidizing, as well as providing excellent protection from bacteria and outside contamination.
