foldover

Having one component that folds over the top of another.

Or the Timeless Bracelet, designed by Ina Seifart: a link-style watchband with a traditional foldover clasp, it has no face at all, just an open spot where you would expect to see one.

Any food prepared by folding, such as a calzone or apple turnover.

Assemble the foldovers and arrange them on a foil-lined cookie sheet; freeze until firm.
