Treatment Pump Bottle

Define the intended application amount and number of actuations, then request pump configurations suited to the formula. Trial the filled assembly and measure delivered output using an agreed method. A small actuator or treatment-pump name does not establish a dose for this bottle.

Include the expected range in pump development trials, checking priming, actuation effort, output, and restart after rest. Use samples representative of the final formulation. Select the pump after those results so a satisfactory fresh-product trial does not become the only performance evidence.

Match the full neck finish, gasket, collar clearance, and dip-tube specification to the selected bottle. Ask the filler to trial application and check filled units for leakage. A matching nominal neck diameter is only one part of establishing a workable dispensing assembly.

Evaluate the selected lock or overcap in the final retail and parcel pack. Test for unintended actuator contact, closure movement, and leakage with filled units. Recheck dispensing afterward so the review includes both containment during handling and acceptable operation when the customer receives it.
