A21 Short-Cap Airless Pump Bottle 30ml & 50ml

Short-Cap Airless Pump Bottle

The A21 short-cap airless pump bottle combines a low-profile cap with a 41mm round body for a wider, compact-looking skincare pack. Its SAN outer bottle surrounds a PP inner reservoir, creating a double-layer construction in two coordinated capacities: 30ml and 50ml.

Material

• Cap: SAN
• Pump: PP
• Shoulder: ABS
• Inner body: PP
• Outer bottle: SAN

Key Features

• Short-cap proportions: The low-profile cap gives A21 a distinct silhouette and keeps the overall design visually compact.
• Wider round body: A shared 41mm diameter gives the 30ml and 50ml versions a consistent footprint. Overall heights are 93mm and 118mm respectively.
• Double-layer construction: The PP inner reservoir holds the formula inside a SAN outer bottle, separating the main container from the exterior presentation.
• Airless dispensing: The rising-piston system dispenses through a pump and helps reduce repeated air exposure during use.

How the Airless System Works

The A21 short-cap airless pump bottle uses an internal piston rather than a conventional dip tube. As formula is dispensed, the piston rises within the reservoir to occupy the space left behind. This limits repeated contact between the remaining formula and outside air. Several initial presses may be required to prime the pump. Actual dispensing performance depends on formula viscosity and compatibility with the complete pack.

Customization Options

• Color: Injection-molded colors or spray-coated finishes can be discussed for the selected components.
• Surface Finish: Evaluate matte, glossy, frosted, soft-touch, metallized or gradient effects against your preferred appearance and the selected surfaces.
• Logo Decoration: Discuss silk screen printing, hot stamping, heat transfer or labeling with your artwork and decoration requirements.
• Packaging Development: Coordinate cap, shoulder and bottle decoration across both capacities. Confirm the final combination with approved samples before production.

Suitable For

A21 can be evaluated for facial serums, lotions, moisturizers and other skincare formulas requiring pump dispensing. The 30ml version provides a shorter pack, while the 50ml version increases capacity without changing the diameter. Choose the capacity around the intended product amount and validate the formula with the selected pump before ordering.

Why This Packaging Works

The short cap and wider body offer brands a different set of proportions within a coordinated airless range. Both sizes share the same diameter, making it easier to maintain a consistent presentation across related skincare products. The separate SAN outer bottle also provides an exterior surface for decoration while the PP inner reservoir forms the main formula container. This allows the packaging team to evaluate appearance, capacity and dispensing as parts of one project.

Filling & Usage Notes

• Filling Recommendation: Confirm the filling route, piston position, fill volume and assembly procedure with approved samples before filling-line setup. Avoid overfilling and trapped air.
• Initial Pumping: Prime with several presses until dispensing begins, then check dose consistency during the filling trial.
• Compatibility Testing: Test ingredients, viscosity, filling temperature and storage conditions using the actual formula and complete packaging.
• Handling: Keep the nozzle clean and replace the cap after use. Evaluate the final filled pack for storage and transport performance before production.

FAQ

What capacities and dimensions are available?

The 30ml version is 93mm high and the 50ml version is 118mm high. Both have a 41mm diameter.

What distinguishes the A21 design?

Its short cap and comparatively wide body give it different proportions from a tall, slim airless bottle. Both capacities use a SAN outer bottle and PP inner body.

What is the minimum order quantity?

The standard MOQ is 5,000 pieces. Confirm the final requirements for your chosen components, colors and decoration.

Can I customize the color and logo?

Yes. Component colors and printing or other decoration can be developed around your artwork, subject to surface suitability and sample approval.

Can I request samples?

Existing samples can be requested for evaluation. Customized samples usually take 7–10 days depending on decoration. Freight is at the customer’s expense.

What is the production lead time?

Standard production normally takes 30–40 days after artwork, color and sample approval.
