lid mechanism
also called opening type
How a refuse bin opens for dropping waste in, hands-free where applicable — open (no lid), a swing lid (a push flap that swings shut behind the waste), a flip-flop lid (a self-closing tilt flap), a sliding lid (a top that slides aside), a lift-off top lid (a loose or fixed cover lifted off) or pedal-operated (a foot pedal raises the lid, hands-free). This waste-access opening is the real differentia of a bin versus a plain open vessel, and the pedal fold lives here (pedal-operated is a VALUE, not a separate property). Distinct from `lid_type` (A11): lid_type is the drinking-spout dispensing interface of a bottle (sipper/straw/sports-spout/bite-valve — how liquid exits). Distinct from `sealing` (A11): sealing is the food-preservation closure of a storage vessel (airtight snap-lock/screw-top/clip-lock/vacuum — how well a lid seals contents in). lid_mechanism is the hands-free waste-access opening of a bin — a bin is deliberately non-airtight and dispenses nothing; the three concepts live on different families, answer different questions and never co-occur. Concern measurement, axis-eligible (a hands-free pedal vs an open bin is a genuine buy choice).
Lid mechanism is answered with one word chosen from the lid mechanisms list — the same word shared across every product that uses it.
It belongs to measurement — its measurable, physical facts.
