strainer

also called colander

A perforated or mesh draining VESSEL with a nominal holding volume that separates solids from liquid — a colander (punched-hole bowl), a basket strainer, a flour sieve/sifter. A child of Container (the holding-volume vessel parent under Product). It INHERITS capacity from Container (a 3L/5L colander's bowl volume, a sifter's cup rating) and earns its own place by `mesh_grade`: the perforation/mesh fineness (perforated holes / wire-mesh / fine-mesh / micro-mesh) that grades what passes through — a slot no other vessel carries, and the whole point of a strainer. The role-named pieces (colander, sieve, flour sifter) resolve here directly, distinguished by the `strainer_type` identity token plus mesh_grade, capacity and shape; Colander / Sieve add no exclusive slot, so they fold as strainer_type values rather than minting classes (the utility_vessel_type fold discipline). It also reuses `shape` (round/oval/square — a colander's geometry). NOTE: small rim/hand strainers spec'd by diameter not litre volume (a tea strainer, a flat skimmer, an oil strainer) are deliberately NOT members — Strainer requires a capacity (inherited from Container) that they do not have; they await a capacity-optional small-strainer home (the b107 bread-box / b111 collapsible-fabric defer discipline). Distinct from a Basket (b111): a basket is an open-walled CARRYING receptacle that cannot hold liquid (keyed by wall_construction for ventilation), whereas a strainer holds liquid transiently and grades what drains through (keyed by mesh_grade). Inherits material and color from Product. Sold across a mesh_grade x capacity x shape x material space; which combinations a seller offers is a downstream Seedbed statement.
