A31 Bottom-Refill Airless Pump Bottle 30ml, 50ml & 100ml

Bottom-Refill Airless Pump Bottle

The A31 bottom-refill airless pump bottle combines a replaceable PP inner body with an acrylic outer bottle. The inner container can be unscrewed and removed from the base for replacement, giving skincare brands a refill format with a familiar capped bottle profile. Three capacities—30ml, 50ml and 100ml—support a coordinated serum, lotion or moisturizer range.

Material

• Cap: Acrylic
• Shoulder: ABS
• Inner Body: PP
• Outer Bottle: Acrylic
• Bottom: ABS

Key Features

• Bottom-access replacement: The inner container is designed to unscrew from the base, allowing it to be replaced while retaining the outer bottle.
• Inner and outer body construction: A PP inner body sits inside an acrylic outer bottle, separating the inner container from the decorative exterior.
• Three coordinated sizes: The 30ml and 50ml versions share a 38mm diameter. The 100ml version has a 43.5mm diameter for a larger format.
• Airless dispensing: A rising piston helps reduce repeated air exposure to the remaining formula during use.

How the Airless System Works

The A31 bottom-refill airless pump bottle uses a piston inside the inner container instead of a conventional dip tube. As formula is dispensed, the piston rises to occupy the space left behind. This helps limit repeated contact between the remaining product and outside air. Prime the pump with several initial presses as needed. Test the selected formula and capacity together to confirm dispensing performance before production.

Customization Options

• Color: Coordinate the cap, shoulder, outer bottle and base with custom colors suited to your brand design.
• Surface Finish: Discuss glossy, matte, frosted, soft-touch, metallized or gradient effects according to the selected surface and sample results.
• Logo Decoration: Evaluate silk screen printing, hot stamping, heat transfer or labeling against the available decoration area.
• Refill Presentation: Develop clear replacement instructions and identify the matching inner container for each size. Confirm the refill supply arrangement and packing requirements with the project specification.

Suitable For

A31 can be evaluated for serums, facial lotions, moisturizers and other skincare formulas suited to airless pump dispensing. The 30ml and 50ml sizes provide compact options, while 100ml offers a larger format. Formula viscosity, ingredient compatibility and required dose should guide sample testing rather than capacity alone.

Why This Packaging Works

The removable inner container gives brands a defined starting point for a replacement-based packaging program. The acrylic exterior can carry the main visual identity while the inner container is changed through the base. The three sizes allow related products to share a consistent appearance. Validate repeated assembly, replacement instructions and the completed decorated pack during development so the refill experience is practical for the intended customer.

Filling & Usage Notes

• Filling Recommendation: Confirm the filling route, piston position, fill level and assembly sequence on approved samples. Avoid trapped air and overfilling.
• Inner Container Replacement: Unscrew the inner container from the bottom using the approved sample procedure. Install the matching replacement for that capacity and confirm that all components are seated correctly.
• Compatibility Testing: Test the actual formula, viscosity, filling temperature and storage conditions before mass production. Include repeated replacement and dispensing checks in the evaluation.
• Daily Use: Prime after assembly when necessary, keep the nozzle clean and replace the cap after use. Validate the filled pack and outer carton for transport.
