Non-Spill Lotion Dispenser Pump 28/410 One-Way Valve Body Lotion Bottle Pump

Every filling factory knows the moment a pallet of finished body lotion bottles reaches a distribution centre and the cartons come back wet. The Non-Spill Lotion Dispenser Pump 28/410 was engineered around that single failure point. A spring loaded one-way ball valve inside the pump chamber closes the discharge path the instant the actuator is released, so residual product is drawn back toward the dip tube instead of weeping past the piston and pooling in the shipper.

The housing is moulded from a high-crystallinity polypropylene grade that keeps the cylinder bore dimensionally stable through a 40 C summer container and a minus 10 C winter warehouse. For lines running three shifts, that stability is what keeps shot weight inside tolerance from the first bottle of the shift to the last, and it is the difference between a brand blaming the pump and a brand blaming the formula.

• Product weeping past the actuator during air freight, leaving oil stained labels and rejected retail cartons at the customer dock.
• Dosage drift after the first five thousand shots as the piston seal takes a compression set on lower cost resin.
• Actuators unlocking inside the shipper so the head deploys and presses against the bottle shoulder under pallet load.
• Dip tube length mismatch on 100ml and 250ml rounds, locking four to six millilitres of product in the bottle and drawing complaints about short fills.

• One-Way Ball Valve: A 316 stainless ball seat closes on release and blocks the discharge path. Leak rate held below 0.05 g per unit in a 72 hour inverted vibration test.
• Virgin PP Cylinder: High crystallinity homopolymer holds bore roundness within 0.05 mm, keeping shot weight at 1.2ml plus or minus 0.15ml over a full production run.
• Locked In Transit: Left-right twist lock engages with a positive click at 30 degrees. Heads stay down through 1.2 m drop tests on 24 bottle cases.
• Three Closure Finishes: 28/410 tooling is available in smooth wall, fine rib and deep rib so the pump matches the cap aesthetic the brand has already approved.
• Food Contact Ready: Resin and masterbatch both ship with REACH and RoHS documentation, and migration test reports are issued per batch on request.
• Pantone Matched Colour: Masterbatch dosing inside the moulding cell keeps shade drift under dE 1.0 between lots, so a refill never looks like it came from another supplier.

Designed for body lotion, hand cream, body milk and after sun products filled on eight to twenty four head rotary lines. The 28/410 neck is the default finish on 250ml and 400ml PET and HDPE bottles used by private label skin care houses in Europe and North America, and it also fits 500ml salon back bar sizes. Filling factories running a multi SKU schedule can keep a single pump stock keeping unit in the warehouse and service several bottle programs at once, which simplifies both minimum order planning and spare parts handling.

Pumps are packed 500 pieces per export carton measuring 49 x 38 x 39 cm, with corrugated dividers keeping actuators upright and separated. Cartons are sealed with reinforced tape and palletised at 32 cartons per layer. Standard production lead time is 15 working days after deposit for uncoloured stock and 25 days for custom colour. Every lot is inspected at three points: incoming resin certificate review, in process shot weight sampling every 30 minutes, and a final AQL 1.0 random pull before packing. Any defect claim supported by carton photographs is settled with replacement or credit within one working week.
