Model ML-201B1
Stable Foam Output Trigger Sprayer for 28/400 & 28/410 Bottles
Plastic PP foam trigger sprayer with a comfortable hand-press trigger, chemical resistance for cleaning agents, and one body that fits both 28/400 and 28/410 bottle necks.
Product Summary
The ML-201B1 is a plastic PP foam trigger sprayer built for household and commercial cleaning liquids. Each pull of the hand-press trigger releases a rich, uniform foam rather than a coarse mist, which helps detergent stay on vertical surfaces such as tiles, glass and worktops. The closure fits 28/400 and 28/410 bottle necks, so a single sprayer part can serve several bottle formats. PP construction and good chemical resistance are intended for kitchen degreasers, bathroom and toilet cleaners, glass and window cleaners, and car care products.
Key Features
Stable Foam Output
The foam nozzle delivers rich and uniform foam, giving end users a predictable dose on every press instead of an uneven sputter.
Fits 28/400 & 28/410 Necks
One sprayer body suits both standard bottle necks, which simplifies purchasing and lowers the number of sprayer parts you keep in stock.
Chemical Resistance
PP material with good chemical resistance supports various cleaning agents used in household, janitorial and automotive formulas.
Comfortable Hand Press
The trigger geometry is designed for repeated hand-press operation, which matters for janitorial teams working through long cleaning cycles.
OEM Colors & Bulk Supply
Bulk orders and OEM customized colors are supported, with a stated annual factory output of 600 million pieces behind the supply.

Models and Options

Materials and Structure
The sprayer body and trigger assembly are moulded in PP. The head uses an inclined pump layout with a single protective cover over the foam nozzle, and the trigger sprayer closure threads onto the bottle neck. Cleaning projects using this unit typically specify chemical resistance and leak-proof performance, with use at normal temperature indoors or outdoors. The manufacturer, Zhejiang Mila Plastic Industry Co., Ltd., holds utility model patents granted by the China National Intellectual Property Administration covering trigger sprayer structures such as lockable triggers, adjustable angle sprayers, locking functions and nozzle protection designs.
