To provide a tableware with a lid of a special mode article which is easily toppled and broken, and reliably and rapidly bound by anybody.

A disposable binding assist tool is formed of a plate having a substantially square shape of the size circumscribing a circular bottom surface (12) of a conical, truncated conical or cylindrical table ware (11), or having a substantially square shape of the size larger than the bottom surface (12) and not extending from the largest outside diameter part of the tableware (11), and sustaining the bottom surface (12) of the tableware (11). By cutting first to fourth string locking grooves (18a), (18b), (18c) and (18d) in a substantially intermediate part of each ridge by the predetermined depth, a binding string (19) for binding and integrating the tableware (11) with its lid (14) is inserted in and locked to the first to fourth string locking grooves (18a), (18b), (18c) and (18d) in a cruciform in bottom view.
