Horizontal Dropper Plug 2.2 A(B) for Ø20 mm Bottles

Horizontal Dropper Plug 2.2 A(B) for Controlled Drop Dispensing

Horizontal Dropper Plug 2.2 A(B) by Farmmash is an internal dispensing component for controlled drop-by-drop delivery of liquid products from compatible bottles.

The dropper plug is fitted into the bottle neck and works as part of a complete packaging system together with a compatible bottle and screw closure.

According to the Farmmash catalogue, 2.2 A(B) can be used together with Closure 1.1 A(B) for Ø20 mm bottle configurations.

Horizontal Drop Formation

The 2.2 A(B) uses a horizontal, edge-type dispensing principle.

For dispensing, the bottle is tilted to approximately 120°. The liquid reaches the dispensing edge, where individual drops are formed.

This principle distinguishes the 2.2 A(B) from vertical dropper designs in which the bottle is normally inverted to a different dispensing position.

Controlled Drop-by-Drop Dispensing

Internal liquid and air-return channels support liquid flow and controlled drop formation during use.

Actual drop size and dispensing rate depend on the properties of the formulation, including viscosity, surface tension and density.

For this reason, drop performance should always be evaluated with the customer’s actual formulation.

Material and Manufacturing

Dropper Plug 2.2 A(B) is manufactured from LDPE (low-density polyethylene).

Injection moulding is carried out in ISO Class 7 cleanroom conditions.

The materials used for the current product specification comply with applicable food-contact and pharmacopoeia requirements.

Compatible Packaging Components

The Farmmash catalogue identifies Closure 1.1 A(B) as a compatible outer screw closure for the 2.2 A(B) dropper plug.

The bottle, dropper plug and closure should be evaluated as one complete packaging system.

Nominal neck diameter alone is not sufficient to confirm compatibility.

Applications

The 2.2 A(B) can be considered for compatible:

• pharmaceutical liquids;
• veterinary products;
• healthcare products;
• nutraceutical liquids;
• cosmetic formulations;
• other liquid products requiring drop-by-drop dispensing.

Final suitability depends on the formulation and complete packaging configuration.

Compatibility and Dispensing Tests

Before serial production, Farmmash recommends evaluating:

• fit of the dropper plug in the bottle neck;
• compatibility with the outer closure;
• sealing performance;
• drop formation;
• dispensing rate;
• performance with the actual formulation;
• compatibility with filling and assembly equipment.
