Claim:
A rice-ball making implement comprising two containers having opened tops and being connected to each other to be openable/closeable, each of said containers being interconnected by a bend part interconnecting upper edges of opposite base-end standing walls comprising; a base element, standing walls with necessary heights projecting from outer peripheral edges of one side of the base element, a containing part formed between the base element and the standing walls to contain foodstuff, wherein: a height of each of upper edges of two side-part standing walls extending from both ends of a base-end standing wall toward a front-side is set to be substantially the same as that of an upper edge of the base-end standing wall near the base end but the height gradually increases toward the front end, the heights of the upper edges of the two side-part standing walls are set to be substantially the same, front ends of the two side-part standing walls are connected by a front-end standing wall, a height of the upper edge of the front-end standing wall is set to be substantially the same as that of the front ends of the upper edges of the side-part standing walls, and the container is made to be slightly larger than the other container so that the side-part standing walls and the front-end standing wall of the latter container may overlap with insides of the side-part standing walls and the front-end standing wall of the former container when the two containers are bent at the bend part in a manner of closing them.
