Specifications

Select a Size and Set the Working Fill

Use 15 mL for a trial or targeted treatment, 30 mL for a daily treatment and 50 mL for a larger lotion or cream SKU. Calculate the required fill volume from formula density and target net weight, then confirm the working fill and headspace with the pump fitted. Request a drawing for each size showing the assembled height, footprint and printable panel before finalizing retail cartons.

Approve the Refill System

Define which parts the customer keeps

Confirm whether the shell, pump or both remain in use when the reservoir is replaced. Specify how a new reservoir ships sealed, how it connects to the dispenser and how users identify a fully seated refill. Test installation with the intended instructions. Agree on the required number of swaps and check the connection, seals, pump fit and finish after repeated use.

Check the first dose after a refill

Run priming and dispensing trials on a new assembly and after a replacement. Record the number of presses needed to prime, the amount delivered per full stroke, and whether the pump drips or sputters. Inspect the shell and joints for product transfer and leakage. Validate the final refill instructions with the product and quality teams before printing.

Test Formula Compatibility and Dispensing

Supply production formula for filled trials. Compare dose and actuation force at the start, after storage and near the end of use. Check for discoloration, swelling, cracking and changes in output over the intended stability program. Define acceptable residual product and document the measurement method. See the airless pump evacuation guide.

Frosted Finish, Logo and Artwork

Provide vector artwork, a color standard and the intended front panel. Review logo contrast on a filled bottle, especially if the formula or reservoir color changes. Approve the position of the logo relative to the pump outlet, ink adhesion and rub resistance. Check the frosted finish across the flat faces and edges and sign off on an assembled decoration sample for each finish.

Filling Trial and Pre-Shipment Inspection

Confirm how the reservoir and pump arrive, how the filler locates the reservoir, and how the pump seats after filling. Share formula temperature, target weight and filling equipment. During a pilot, check fill repeatability, trapped air, joint fit and priming. Agree on cosmetic defect limits for panel scratches, uneven frosting, corner damage and print alignment. Trial the packed bottles and refills for scuffing, loosening and leaks under representative handling conditions.

OEM Quotation and Export Packing

Send your size split, working fill, formula type, target dose, finish, artwork and refill requirements. Request separate pricing for the complete bottle and any spare reservoirs, plus samples, decoration and tooling where applicable. Confirm production timing after approval, carton quantity and dimensions, gross weight and freight terms. Retain signed samples and batch details for quality follow-up. Request a Boyu Packaging quotation.
