THE RIM SUPPLY INDEX
Cup + lid records
Why should a lid order start with the cup code?
A cup model identifies more than its ounce capacity or a nominal rim number.
Is a lid’s outside edge the same measurement as the cup’s rim?
A nominal matching-rim category is not a measured lid outside diameter or a tolerance test.
Can two sixteen-ounce cups use the same lid?
Capacity is not an attachment specification, even within one supplier’s catalog.
What does a source-matched cup-and-lid result actually prove?
A published matching entry is useful evidence, but it is not a measured seal or transport result.
