Refillable Pump Bottle with PLA Bottle and Cap

Develop a distinctive skincare refill concept with this pump bottle, featuring a PLA outer shell, matching PLA cap, and replaceable inner cartridge. The design separates the visible exterior from the inner product reservoir, creating a modular packaging structure rather than a single container. The cartridge fits inside the cylindrical shell, while the pump assembly completes the dispensing configuration. This structure provides a clear starting point for brands planning replacement cartridge offerings alongside their initial packaged products.

Consider this format for lotions, emulsions, and other pump compatible skincare formulas, with compatibility and dispensing performance confirmed before production. Packaging development should also establish the cartridge replacement procedure, pump reuse requirements, sealing performance, and filling process.
