28-410 No Flip Cap with Valve for Inverted Dispensing | Liquid Dishwashing Bottle Cap

The 28-410 no flip cap with valve is a next-generation inverted dispensing cap designed specifically for concentrated liquid detergents and dishwashing formulations. With an outer diameter of 56mm and a standard 28-410 neck finish, this cap is engineered for stable, controlled dispensing in upside-down bottle applications.

Unlike traditional caps, this design eliminates the need for a flip-top or pump system. It integrates a food-grade liquid silicone valve that enables one-press, one-dose dispensing—ensuring liquid only flows when the bottle is squeezed.

This liquid dishwashing dispensing cap is widely used in:

• - Dishwashing liquid bottles

• - Kitchen cleaning concentrates

• - Surface cleaners

• - Laundry detergent concentrates

• - Household chemical cleaning products

• - Industrial cleaning liquids (mild formulations)

Key Features of 28-410 Liquid Dishwashing Dispensing Cap:

• No flip-top design (fully sealed structure)

• Inverted dispensing functionality

• Leak-proof silicone valve system

• Controlled, metered output (one squeeze = one dose)

• Anti-drip and anti-stringing performance

• Suitable for concentrated dishwashing and cleaning liquids

Using the inverted dispensing cap is simple and intuitive: install it onto a 28-410 neck bottle (compatible with PET, PP, and PE bottles), invert the bottle with the cap facing downward, and gently squeeze. The silicone valve opens automatically to release a controlled amount of liquid, and once pressure is released, it closes instantly to prevent dripping. Each squeeze delivers a consistent, metered dose, ensuring efficient and clean dispensing.

Our 28-410 no flip cap with valve is produced under a fully controlled system to ensure precision, hygiene, and stable performance. It uses high-precision injection molding for food-grade PP components, while the silicone valve is made from liquid silicone (LSR) with precision slit cutting to ensure controlled dispensing and leak-proof performance. The product is assembled on fully automated lines with integrated valve insertion to eliminate human error, and each unit is 100% CCD inspected for defects such as missing valves or deformation. Production is carried out in an ISO22000-certified clean workshop, ensuring consistent quality and reliable performance in every batch.

The 28-410 no flip liquid dispensing caps are packed in clean polybags and export cartons to ensure hygiene and safety during transit. Custom packaging and palletization are available for bulk orders.
