Bottle Cap Inspection AI: Detect Sealing Issues
Learn how to build a bottle cap inspection model that catches missing, high, and cocked caps with computer vision.
Add a real-time inspection layer to every capped unit on the line with vision AI for cap and closure inspection. Built for the operations where one high cap that leaks in transit, cocked closure that fails at the customer's DC, or missing tamper band on a regulated product can mean a rejected pallet, a chargeback that follows the SKU for quarters, or a compliance finding. Whether you're running ROPP caps on a rotary capper, flat caps at 1,200 bottles per minute, pumps and triggers on personal care lines, or child-resistant closures on OTC product, Roboflow extends your inspection coverage to every unit at line speed, validatable under FDA 21 CFR Part 11 and cGMP.

What is cap and closure inspection with Vision AI?
Cap and closure inspection with vision AI uses computer vision models to inspect every capped unit as it leaves the capper: cap presence, application height and angle, tamper band integrity, seal and liner presence, and cap type and color against the active SKU. Models trained on your actual closures and line conditions make the check on every unit at full line rate rather than sampled pulls, with per-unit records that support FDA 21 CFR Part 11, cGMP, and FSMA requirements.
Can Vision AI catch high and cocked caps at full line speed?
High and cocked caps are millimeter-scale defects moving at hundreds to over a thousand bottles per minute, often on glossy caps that throw glare under line lighting. Deep-learning models trained on your closures, your bottles, and your lighting recognize the geometry of a properly seated cap and flag the units that sit proud or tilted, running on edge hardware at capper rates so every bottle gets inspected without slowing the line. Because every flagged unit carries imagery and a timestamp, recurring defects trace back to the specific capping head that produced them.
Does cap and closure inspection support FDA tamper-evident packaging requirements?
Yes. Roboflow models can run as documented inspection controls that support FDA tamper-evident packaging requirements for OTC drug products (21 CFR 211.132), cGMP batch documentation, FSMA traceability, and FDA 21 CFR Part 11 electronic records, with per-unit inspection history, model version control, and training data lineage for audits. Roboflow is the inspection engine; your quality and regulatory teams own the acceptance criteria.
Can it integrate with our cappers, reject systems, and MES?
Yes. Roboflow Inference exposes a standard API and supports common industrial protocols, so closure inspection events flow into your existing systems: filling and capping lines from Krones, KHS, and Zalkin, line PLCs from Allen-Bradley and Siemens, SCADA and HMI platforms like Ignition and AVEVA, MES and ERP systems like SAP and Oracle, through REST, MQTT, OPC UA, and direct database writes. PLC-level integration drives rejects, diverts, and capper stops the moment a bad closure appears, with a full audit trail behind every decision.
