Complete Automation for Premium Dropper Bottle Assembly and Filling

The LR-200 Automatic Monoblock addresses the complex technical challenges of packaging low-volume, high-precision liquid products that require a dual-component closure system. This advanced machine is purpose-built for the complete assembly of dropper bottles, a format ubiquitous in pharmaceuticals, aromatherapy, and high-end cosmetics for its controlled, precise application. The process begins with empty vials being gently queued and singulated on the infeed accumulation table, ensuring a steady, organized feed into the rotary carousel. Each container then receives a meticulously accurate fill of your precious product—whether a sensitive ophthalmic solution, a volatile essential oil, or a viscous cosmetic serum—from the machine’s core twin-piston dosing system. The filled vial then proceeds through two critical sealing stages: first, a plugging head accurately seats a sterile elastomeric dropper plug into the bottle neck, and second, a screw capping head applies and torques the outer threaded plastic overcap. This integrated approach is indispensable for manufacturers of prescription eye drops, over-the-counter nasal sprays, therapeutic essential oil blends, anti-aging facial serums, and perfume roll-ons, eliminating the inefficiency, contamination risk, and inconsistency of manual assembly while delivering a professionally finished product that inspires consumer confidence and ensures precise dosage delivery.

Detailed Technical Specifications & Advanced Configuration

• Machine Type & Layout: Fully Automated Rotary (Carousel) Monoblock with Integrated Infeed Rotary Accumulation Table and Outfeed Discharge Chute. This design provides crucial buffering and singulation for small, sometimes irregular containers, maximizing line uptime and smooth operation.

• Core Filling Technology: Precision volumetric dosing system employing two (2) AISI 316L stainless steel piston cylinders with sanitary check valves. This setup is optimized for the small fill volumes (e.g., 1ml to 30ml) typical of dropper bottles, providing exceptional accuracy (±0.25% or better) to minimize costly giveaway of expensive ingredients.

• Dual-Closure Sealing System: A two-stage sealing station featuring:

  1. A plugging head (stopper insertion head) designed to accurately pick and place dropper plugs (dropper inserts/elastomeric stoppers) into the vial neck.

  2. A screw capping head that subsequently applies and tightens the outer plastic screw cap over the inserted plug.

• Component Feeding & Handling: Includes two (2) vibratory bowl feeders for the automated, oriented supply of both the dropper plugs and the plastic screw caps to their respective application heads. The system is engineered for the gentle, secure handling of delicate small glass vials and bottles throughout the process.

• Construction & Hygiene Standards: All wetted parts and product-contact surfaces are AISI 316L / 1.4404 stainless steel, ensuring compatibility with a vast range of pharmaceutical, aromatic, and cosmetic formulations without risk of corrosion or contamination. The GMP-ready design supports rigorous cleaning and validation protocols.

• Control & Process Management: Centralized PLC with multi-language HMI touchscreen allows for complete control over fill volume, plug insertion depth, cap torque, and machine speed. The system supports recipe storage for different product-container combinations, facilitating fast, error-free changeovers.

Ideal Product Applications & Packaging Formats

• Target Products: Perfectly suited for low-volume, high-value liquid products: ophthalmic solutions (eye/ear drops), nasal sprays, essential oils and blends, cosmetic facial serums and oils, perfume concentrates, tinctures, and pharmaceutical oral drops.

• Target Containers & Closures: Specifically designed for small glass or plastic vials and bottles (typically 5ml to 50ml) that utilize a dual-closure system: an inner elastic dropper plug (dropper insert) and an outer plastic continuous-thread (CT) screw cap, often with a built-in pipette or orifice.

Strategic Business Advantages for Specialized Markets

• End-to-End Process Integration & Labor Savings: By combining filling, plugging, and capping into one synchronized machine, you eliminate multiple manual stations, reduce labor costs, minimize handling-related contamination risks, and significantly accelerate your overall packaging throughput for dropper bottle products.

• Ultra-Precise Filling Maximizes Product Yield: The precision piston-dosing system delivers exceptional accuracy for small volumes, drastically reducing product overfill. This leads to direct and substantial cost savings when filling with expensive active pharmaceutical ingredients (APIs), rare essential oils, or premium cosmetic concentrates.

• Guaranteed Closure Integrity & Dosage Accuracy: The automated, sequential application of the dropper plug and screw cap ensures a consistent, reliable seal every time. This protects product sterility and potency, prevents leakage and evaporation, and guarantees the dosage accuracy critical for pharmaceutical efficacy and consumer satisfaction.

• Enhanced Flexibility for Diverse Product Portfolios: The quick-change tooling and recipe-driven controls allow manufacturers to efficiently switch between different bottle sizes, dropper plug types, and cap styles. This agility is ideal for contract packagers and brands with diverse SKUs, enabling small-batch production runs without major downtime.

• Globally Validated for Regulated Industries: Constructed with GMP and FDA guidelines in mind, the machine supports the documentation needs for IQ/OQ/PQ validation. Coupled with international certifications (CE, ISO) and our worldwide technical support network, it provides a compliant, reliable foundation for production aimed at both local and export markets across Southeast Asia, the Middle East, Africa, and beyond.
